Embodiments of the present invention

After the research and analysis of the applicant, in order to improve the grinding efficiency, the cylinder to be polished is effectively transported by using the conveying plate, and the cylinder is directly transferred to the grinding knife for grinding. In the actual grinding process, the speed of the grinding knife is very fast, so the grinding knife has a certain force on the cylinder being polished, and the force is transmitted to the conveying plate through the cylinder, so the conveying plate is under the action of external force Unnecessary rotation can occur, and this rotation causes the cylinder being polished to move, which not only affects the precision of the grinding, but also affects the progress of feeding the opposite side.

Example 1

In order to solve this technical problem, the present embodiment provides a grinding device as shown in Figure 1, comprising a stand 1, a turning mechanism 2 is arranged on the stand 1, a grinding knife 3 is connected to the turning mechanism 2, and the grinding knife 3 Send out and be provided with polishing table 4, and polishing table 4 is fixed on the stand 1. In this embodiment, the rotating mechanism 2 is a prior art, so it will not be repeated here.

Wherein, the interior of the grinding table 4 is provided with a conveying tray 5. In order to realize the two processes of simultaneous feeding and grinding, several downwardly recessed grooves 6 are provided at the edge of the conveying tray 5, and the cylinder 7 to be polished is placed Transport in groove 6. In order to facilitate later control in time, the distances between adjacent grooves 6 are the same. In order to drive the conveying disc 5 to rotate to realize the transportation and grinding of the cylinder 7 to be polished, unified management is carried out in terms of time. If the distances between adjacent grooves 6 are different, it is difficult to control the pairing between the feeding mechanism 18 and the grooves 6 . In this embodiment, the transmission mechanism is connected to the axis of the conveying disc 5, and the conveying disc 5 rotates intermittently under the drive of the conveying mechanism, and when the conveying disc 5 stops rotating, the conveying mechanism is in a locked state. The knife 3 grinds the cylinder 7 to be polished below.

In order to realize the above functions, as shown in FIG. 2 , the conveying mechanism includes: a fixing member 8 , a cam 9 , a connecting member 10 and a chuck, and the chuck and the conveying disc 5 are coaxially connected. Wherein, one side of the fixing member 8 is fixed inside the stand 1, which can be fixed by welding or fixedly connected by bolts. The cam 9, the connecting piece 10 and the chuck are all rotatably mounted on the fixing piece 8 respectively, wherein the connecting piece 10 is triangular in shape and includes a first vertex 11, a second vertex 12 and a third vertex 13. A vertex 11 is hinged to the fixing part 8 to realize the connection relationship between the connecting part 10 and the fixing part 8 . A roller is installed at the second apex 12 , and the rolling surface of the roller is in contact with the rolling surface of the cam 9 . A stickle 14 is hinged at the third corner 13 . In order to fit the stickle 14 , the chuck includes: a body 15 and a plurality of slots 16 equidistantly provided on the outer wall of the body 15 . And in order to realize the pushing effect of the handlebar 14 on the chuck, the cam 9 includes a wave section 901 and an arc surface 902 connecting the two ends of the wave section 901 and protruding outward.

In a further embodiment, the wavy surface includes: a first convex surface and a second convex surface connected to the two ends of the arc surface 902, and a first concave surface connected to the first convex surface A surface, a second concave surface connected to the second convex surface, and a third convex surface connected to the first concave surface and the second concave surface.

During use, the shaft center of the cam 9 is connected to the output shaft of the drive motor. When the roller at the second vertex 12 is positioned at the arc surface 902 of the cam 9, the second vertex 12 is at the top, and the circle of the cam 9 The arc surface 902 has an upward push-out effect on the second corner 12, so that the third corner 13 and the handle 14 installed at the third corner 13 are pushed out to move toward the chuck and make the handle 14 located in one of the slots 16 Inside, the chuck pauses at this time; the cam 9 continues to rotate, and when the roller is on the first convex surface, the second corner 12 is slightly raised, and the third corner 13 and the third corner 13 The sticky handle 14 is slightly lifted up, and the sticky handle 14 is slightly separated from the slot 16. When the roller is located on the first concave surface, the sticky handle 14 continues to move down, and is separated from the current slot 16 and moves to the next slot 16. The roller is positioned at During the second concave surface, the sticky handle 14 is clamped with the draw-in groove 16, and when the roller is positioned at the second convex surface, the second corner 12 is jacked up, then the third corner 13 and the sticky handle 14 at the third corner 13 Slightly jacked up, then thorny 14 moves upward against the draw-in groove 16 where now, and the chuck is pushed so repeatedly.

In order to lock the chuck when the chuck stops rotating in the above structure, a protrusion 17 extending to the chuck at a predetermined height is provided between the first vertex 11 and the third vertex 13; When located at the arc surface 902 (when the sticky handle 14 is fastened to the locking groove 16), the protrusion 17 is stuck in the corresponding locking groove 16, which plays a very good locking effect.

In other words, based on the above structure, the intermittent rotation of the conveying disc 5 can be realized, and at the same time, when the conveying disc 5 stops rotating, the protrusion 17 locks the chuck, and when the grinding knife 3 applies an external force to the cylinder 7 to be polished, no It will cause the rotation of the conveying disc 5, which increases the stability and precision of grinding.

However, in the above embodiments, although the transport disc 5 is fixed to ensure that the transport disc 5 will not rotate under the action of the grinding knife 3, the cylinder 7 to be polished is placed inside the groove 6 , that is, without other fixing effects, it cannot be ensured that the cylinder 7 to be polished located in the groove 6 will not rotate itself. And the space in the groove 6 is also quite compact, how to fix the cylinder 7 to be polished in a limited space has become a difficult point.

In a further embodiment, in order to solve the above technical problems, this embodiment discloses a clamping mechanism, which is arranged in the groove 6 . The clamping mechanism clamps and fixes the cylinder 7 to be polished. As shown in Figure 3, the clamping mechanism includes: a bracket 601 fixed on the inner wall of the groove 6, at least two groups of clamping pieces 602 are arranged on the edge of the bracket 601, and in this embodiment, the number of clamping pieces 602 is Three groups are evenly distributed. In order to control the working state of the clamping member 602 , an electric cylinder is arranged under the bracket 601 , and the electric cylinder is a small cylinder. The piston rod of the electric cylinder is connected with a pusher 603, and the pusher 603 is connected with a connecting rod assembly, and the connecting rod assembly is connected with the clamping member 602 at the same time. Moving toward the bracket 601, the connecting rod assembly pushes the clamping member 602 to clamp.

In order to better illustrate the above structure, for example, the clamping member 602 includes: a rotating shaft 6021 rotatably installed on the bracket 601, connecting blocks 6022 are fixed at both ends of the rotating shaft 6021, and a connecting block 6022 is arranged between the two connecting blocks 6022 A connecting shaft 6023, the connecting shaft 6023 is in transmission connection with the connecting rod assembly. The top ends of the two connecting blocks 6022 are provided with a clamping block 6024 extending upward to a predetermined height. In other words, when the connecting rod assembly pushes the connecting shaft 6023 to move outward, the clamping block 6024 rotates inward with the rotating shaft 6021 as the center of a circle, and plays the role of clamping and fixing the cylinder 7 to be polished.

In a further embodiment, the connecting rod assembly includes: a first connecting rod 6025 hinged to the pusher 603 , a second connecting rod 6026 hinged to the first connecting rod 6025 , and the second connecting rod 6026 is hinged to the connecting shaft 6023 at the same time.

The working principle of the clamping mechanism is as follows: when the electric cylinder is in the compressed state, the pusher 603 is at the lowest end, at this time the angle between the first connecting rod 6025 and the second connecting rod 6026 is the largest, and the connecting shaft 6023 and the bracket The distance of the axis of 601 is the shortest, and the clamping block 6024 at this time has no fixing effect on the grinding cylinder. When the cylinder 7 to be polished is placed in the groove 6, it is placed on the support 601. When the grinding cylinder needs to be fixed before grinding, the piston rod of the electric cylinder pushes out the pusher 603, and the pusher 603 gradually moves upwards. During this process, the clamp between the first connecting rod 6025 and the second connecting rod 6026 The angle decreases, and the connecting shaft 6023 is ejected outwards. At this time, the clamping block 6024 rotates inward with the rotating shaft 6021 as the center of circle, and plays the role of clamping and fixing the cylinder 7 to be polished.

Based on the above description, the cylinder 7 to be polished is fixed by a compact clamping mechanism, which avoids the rotation of the cylinder during grinding, increases the stability during the grinding process and improves the grinding accuracy.

In the above embodiments, the cylinder in the groove 6 is transferred to the grinding knife 3 through the conveying disc 5, and in order to facilitate transportation, there is a certain distance between the grinding knife 3 and the cylinder itself, so it is necessary to Only when the cylinder or the grinding knife 3 is moved up or down can the effective grinding process be carried out, and if the grinding knife 3 is moved down, it is very likely that several grinding knives 3 will be polished at the same time or come into contact with other cylinders 7 to be polished , As a result, effective control and transportation cannot be carried out later, and there will be inconsistencies in the degree of grinding between each cylinder, which directly reduces the qualified rate.

In order to solve the above problems, the applicant has made further improvements to the clamping mechanism: an ejector rod 604 is provided at the axial position of the bracket 601, and the bottom of the ejector rod 604 is drive-connected to the piston rod of the electric cylinder.

In other words, when the piston rod pushes the pusher 603, the ejector rod 604 is pushed out at the same time, and the ejector rod 604 pushes out the cylinder 7 to be polished, thereby increasing the height of the cylinder 7 to be polished that is about to be polished. When the cylinder 7 to be polished that needs to be polished is in contact with the grinding knife 3 to facilitate grinding, the height of the cylinder 7 to be polished and other cylinders to be polished is lower than the height of the cylinder being polished, which realizes targeted and one-stop One-to-one grinding improves the pass rate of products.

In a further embodiment, in order to match the feeding time with the turning and grinding time. The grinding device of this embodiment also includes a feeding mechanism 18 arranged on the opposite side of the rotating mechanism 2 . The feeding mechanism 18 includes: a placing frame 1801 arranged on the stand 1 , a through hole 1802 is opened at the center of the placing frame 1801 , and the placing frame 1801 is configured to place a storage bucket 1803 . In this embodiment, the cylinders 7 to be polished are stacked on the inside of the material storage barrel 1803 in sequence, and the inside of the material storage barrel 1803 is an open structure. When the material storage barrel 1803 is placed on the placement frame 1801, the open structure When aligned with the conduction hole 1802 , the cylinder 7 to be polished is discharged from the open structure and the conduction hole 1802 into the groove 6 on the conveying tray 5 in sequence. In order to control the feeding speed, a sliding cover 1805 is provided under the conduction hole 1802 , and one end of the sliding cover 1805 is connected to the driving cylinder 1804 , and the driving cylinder 1804 is fixed on the placement frame 1801 .

And in order to realize accurate feeding and provide enough grinding time from the time, so in this embodiment, the time t=t1+t2 when the sliding cover 1805 is closed; where t1 represents the grinding time for the conveying disc 5 to stop rotating; t2 represents the conveying time for the conveying tray 5 to transfer the next groove 6 to the feeding mechanism 18 . By setting the sliding cover 1805 and the closing time of the sliding cover 1805, the feeding rhythm of the feeding mechanism 18 is controlled. This rhythm conforms to the sum of the grinding time and the turning time, so as to ensure that the cylinder can just fall on the groove 6 every time feeding. Inside.

In a further embodiment, in order to allow the sliding cover 1805 to support several cylinders 7 to be polished, slots 16 are symmetrically provided at the bottom of the placing frame 1801 , and the two sides of the sliding cover 1805 are located in the slots 16 . The slot 16 not only serves as a guide for the sliding cover 1805, but also as a support. When the sliding cover 1805 is in a closed state, it can support more cylinders 7 to be polished.

However, in the above embodiment, when the slide cover 1805 is directly used to control the feeding rhythm of the feeding mechanism 18, when the slide cover 1805 blocks the current slide cover 1805 and the next slide cover 1805, the following phenomena will occur. If it is closed, the current slide cover 1805 is blocked. If the next slide cover 1805 is blocked or falls ahead of time, the rhythm of feeding will not be controlled, and the cylinder 7 to be polished will fall into the groove 6. It is placed obliquely, so there are serious processing accidents during grinding.

Therefore, guide groove 1806 is provided as a buffer section to solve the above-mentioned problem. Feeding mechanism 18 is arranged on one side of conveying tray 5, and guide groove 1806 is provided between feeding mechanism 18 and conveying tray 5. The guide groove 1806 is arranged obliquely between the conveying tray 5 and the through hole 1802 . In order to allow the cylinder 7 to be polished in the guide groove 1806 to accurately fall into the groove 6, a guide column 1807 is fixed at the bottom of the guide groove 1806, and the guide column 1807 is provided on the side close to the guide groove 1806. The notch 1808 with a predetermined thickness is recessed downwards, and the edge of the notch 1808 is at the bottom of the guide groove 1806 to resist, so that the cylinder 7 to be polished in the guide groove 1806 can smoothly transition into the guide column 1807, and through the guide The post 1807 is transferred into the groove 6 .

In order to ensure that the cylinder 7 to be polished falling into the groove 6 is horizontally placed in the groove 6, the bottom of the guide column 1807 extends to the top of the groove 6, and the guide groove 1806 is provided with an inclined guide column 1807, one end of the guide rod 1809 is fixed to the top of the guide column 1807 (in order to ensure that the cylinder body 7 to be polished moves from the guide groove 1806 to the guide column 1807 without partial tilting or turning over, so as to achieve The cylinder 7 is placed horizontally when it falls into the groove 6), and the other end is close to the outer edge of the via hole 1802 (does not affect the cylinder 7 to be polished to fall from the via hole 1802). In this embodiment, the closing time of the sliding cover 1805 is t=t1+t2-t3; where t1 represents the grinding time for the conveying disc 5 to stop rotating; t2 represents the transfer of the next groove 6 to the feeding mechanism 18 by the conveying disc 5 The delivery time; t3 represents the time for the cylinder 7 to be polished to move in the guide groove 1806.

Based on the above-mentioned embodiments, a polishing method of a cylindrical polishing device specifically includes the following steps:

Step 1. Stack the cylinders to be polished in sequence in the storage tank, and connect the bottom of the storage tank to the conduction hole. At this time, the cover plate is in a closed state;

Step 2: start the conveying mechanism, the conveying mechanism rotates the conveying plate, and when the groove on the conveying plate is located under the conduction hole or the guide column, the conveying mechanism stops rotating;

When the conduction hole on the placement rack is located above the conveying tray, the cylinder to be polished in the storage tank directly passes through the conduction hole and enters the groove. At this time, the closing time of the sliding cover is t=t1+t2 .

When there is a guide groove between the placement frame and the conveying plate, the cylinders to be polished in the storage barrel will pass through the conduction hole in turn, transfer to the guide column along the guide groove, and fall into the corresponding groove through the guide column When it is guided into the groove, it is limited by the guide rod. During the movement of the cylinder to be polished, the cylinder to be polished will never tilt or roll over. At this time, the closing time of the sliding cover is t=t1+t2- t3.

Step 3, the conveying mechanism continues to rotate, and execute step 2; place the cylinder to be polished in the groove in turn; when placing, place the cylinder to be polished on the bracket, and the piston rod of the electric cylinder is in a compressed state at this time, and the pusher Located at the lowest end, the angle between the first connecting rod and the second connecting rod is the largest, and the distance between the connecting shaft and the axis of the support is the shortest, and the clamping block at this time has no fixing effect on the grinding cylinder.

Step 4. On the other hand, when performing steps 2 to 3, when the conveying mechanism is in the suspension of transportation, the clamping mechanism located in the groove directly below the grinding knife clamps the cylinder to be polished and pushes it out. The top surface of the grinding cylinder is in contact with the grinding knife, and the grinding knife is always in the grinding state: the piston rod of the electric cylinder pushes out the pusher, and the pusher gradually moves upwards. During this process, the gap between the first connecting rod and the second connecting rod The included angle decreases, and the connecting shaft is ejected outwards. At this time, the clamping block rotates inward with the rotating shaft as the center of the circle, and plays the role of clamping and fixing the cylinder to be polished. At the same time, when the piston rod pushes the pusher, the ejector rod is ejected at the same time, and the ejector rod ejects the cylinder to be polished, which increases the height of the cylinder to be polished that will soon need to be polished. The contact between the body and the grinding knife is convenient for grinding, and the height of the polished cylinder and other cylinders to be polished is lower than the height of the grinding cylinder.

In a further embodiment, a recording medium is also disclosed, which is a non-transitory recording medium that can be read by a computer, and the recording medium is recorded with a program for causing the computer to perform the following steps:
