Abstract

PURPOSE:To make a loader compact, to make the occupancy space of the loader small when being moved, and to reduce a waiting time by providing a rotating arm constituted with two fork-like arms with loader chucks opened at an angle overlapping the position of two main shaft chucks. CONSTITUTION:A loader 25 is comprised of a shaft 23 provided rotatably and movably back and forth on two main shafts 21, 22 and a rotating arm 24 constituted with two fork-like arms with two pairs of loader chucks provided at the tip and opened at an angle overlapping chucks 21, 22 so that two works can be conveyed to the main shaft chucks 21, 22 at the same time. Eventually, the rotating arm 24 is formed in a hand-like shape made of four arms opened at an angle of 45 deg. apart, and the occupancy space S2 is small when the arm 24 is moved back and forth while facing upward, and the below space is made a large free space because the angle formed between the chuck 31 and chuck 34 is 225 deg., which is much larger than 180 deg..

Description

[Detailed description of the invention]

This invention provides a workpiece weighting method using the rotary +lH, >, s @ and the rotary ■ having two spindle chucks and a loader that receives and delivers the workpiece between the two upper spindle chucks. Regarding. Two main shafts? It is the first lathe that can perform IJ [] machining on the front and back sides of a workpiece in one cycle using the two main spindles.
There is a pivot shown in the figure. In other words, this rotary kiln has two main shaft chucks (1) (2).
And, there is a rotatable shaft (3) installed above the spindle chucks (1) (2) and an X-shaped swing arm (4). A loader (5) that supports the rotor and a fixed chuck (6) provided above the rotor (5).

(S line in Figure 41).
2+ and turret tool rest (91(10)) The existing turret tool rest (91(10)) has a large debt ownership interest, and the layout of the device H below it has been greatly restricted. That is, in general, the turret tool rest (9) (10) &:
As shown in Fig. E'1, when the machine is installed in an inclined position, compared to when it is installed horizontally, the chips that accumulate on it naturally gather on one lower side and fall, and are not removed. However, in the lathe shown in Fig. 1, the space occupied by the loader (5) during movement (Sl) is extremely large downward, so the turret tool rests (9) and (10) are required. If the turret tool rest (91 (10) The space occupied during movement of the loader (5) or the space occupied during movement of the loader (5)
), there is an inconvenience that the movement of the loader (5) and the movement of the turret (9) and (10) must always be interlocked.
Even with such control, the above-mentioned turning egg weight start (

Similar to the lathe shown in Fig. 1, the swing arm (24) of this lathe is open at its tip so that two workpieces can be transferred to the spindle chucks (21) and (22) at the same time. It is composed of two sets of forked arms, but these two sets of forked arms are not located in symmetrical positions around the shaft (23), that is, they are not in an X-shape, but the two sets of forked arms are The included angle (α) between the arms is arranged at an acute angle as shown below, and is fixed to the shaft (23).In other words, the included angle (α) is (24) or directly above the loader chuck (3) of one set of arms.

Since the loader (25) is now empty, the loader (25) is then rotated approximately 90 degrees in the direction of the arrow to bring it into the state shown in the off-line diagram (c). In this state, the loader (25)'kf & retreats to remove the unQoed workpiece (Wp) and semi-IJIIIed workpiece αq) on the loader (31) (32) and the empty spindle chuck (22) (21) Pass it to (・Off diagram H→). Next, the loader (25)' is rotated approximately 185 degrees in the direction of the arrow, and if the loader (25)k is again placed directly above, one of the

The turret tool rest (91 (10)) is connected to the spindle chuck (11 (
21 and could not start turning, but since the loader (25) is not X-shaped in this turning, if the loader (25) was in the state of Immediately, the space below the loader (25) opens wide,
The turret tool rest (29) (30) can be brought close to the main Nakayama chucks (21) (22) completely regardless of the position where the loader (25) protrudes toward the 111 direction. In other words, the υ]l work can be started without the above-mentioned waiting time. In addition, in the lathe shown in Fig. 1, the spindle chuck (1) (21 and the rotor' (5)

As is clear from H →, the process of loading the work to the loader chucks (31) (32) of one set of arms and the process of loading the work to the ±11i111 Nayasoku (21) (22) are separate processes. Therefore, it is not necessary to use the front/back flipping device (28) and the spindle chuck (21) (
22) do not need to be on the same plane (Figure 8 (b)),

8) The work chucked above (loader C25 to avoid interference with W3) requires less protrusion during movement. That is, it is sufficient that the rear surface of the work chucked on the loader chuck (31) protrudes enough to freely pass in front of the spindle chuck (21). This reduces the cycle time and reduces the buckling of the loader (C25) shaft (C25) because the loader (25) has a large number of front and back shafts (C25).

If the character q (7) o-event page 5) is used, the opening angle of the two prongs of the bifurcated arm will be too large, and the rib 11 will become a loader or a cross-shaped arm, making it bulkier. The space it occupies when turning and moving back and forth is extremely large,
Even in the case of an extremely irregular platform, the two sets of bifurcated arms overlap each other and intersect, allowing the entire loader (25) to be suspended in a compact V. In other words, the opening angle 1' of the spindle chuck (21) (22) with the entire center of the shaft (23)

If you turn it upward (as shown in Figure 79), the l cycle is completed. As described above, the above-mentioned method of machining both the front and back sides of the workpiece in one cycle using the front-back reversing device (28) has the advantages of IL! ! Since the rotating direction of the swing arm (24) of the loader (25) is one direction, the motor (■) that rotates synchronously with the loader shaft 1 shaft (2B)' described in J.

Next, the loader (25) is further rotated to transfer the finished workpiece (Wr) on the loader chuck (33) onto the unloading chute (56). 25) 'e, Now turn it in the opposite direction and put it in the state shown in Fig. 10 (to).

The soil work (Wp) (Wp) is loaded rL, and since there is no loading on the other arm of the cap, the rotor (25)' is rotated clockwise in the figure again. '10 Return to the initial state shown in Figure (A) to complete one cycle. The workpieces on the main spindle chucks (21) and (22) have been subjected to turning processing, and the turned workpieces have cwr>cNr>. As is clear from the above explanation of the Qll upper process, the lathe of the present invention has a workpiece loading and unloading chute (55) (
56), the swing arm is not X-shaped, so the arm and turret tool rest (9) (10) or the spindle chuck (1) (
2) and 2) will not interfere with each other. Therefore, the workpiece loading and unloading chute (55) (
56) Only one iJ is required, which lowers the cost r, and also makes it possible to process both the front and back of the workpiece in one cycle. (25) Turning angle 1is Turning order? By simply changing the part of the work piece [[[I+ only, it can be used for υ11 machining. As is clear from the explanation below, the lathe and loader chuck of the present invention have a swing arm consisting of two sets of bifurcated arms that are open at an angle of two spindles at the position of the two main spindle chucks. The two sets of bifurcated arms are not in symmetrical positions with respect to the center of the shaft TF, and are not in an X-shape, making the loader compact and occupying a small space when moving the loader. In addition to freeing up the layout of wells, the cycle time is shortened by eliminating the waiting time mentioned at the beginning. In addition, in the workpiece processing method using this lathe, the delivery and reception of the workpiece to the loader is always performed in a separate process for each set of bifurcated arms.
Like the lathe shown in Figure 1, workpieces are delivered and received in the same process using two sets of bifurcated arms (Figure 2 (c)).
Since the spindle chuck position IR and the position of the front/back reversing device A do not need to be aligned on the same plane, this increases the portability of the loader and shortens the cycle time of the soil. I can do something. Also, according to the I) Roe method for workpieces using this lathe, the workpieces were individually loaded from one chute onto one set of bifurcated arms and chucked into the spindle chuck. Simultaneously loading the two processed workpieces into the other set of forked arms to simultaneously empty the spindle chuck and emptying the unprocessed workpieces loaded onto the one set of forked arms. Simultaneously transfer to the main spindle chuck and transfer it to the forked arm of the other set? Since the two finished workpieces are transported to the 1st unloading chute, the kumite unloading chute is 1st each.
It can handle two workpieces at the same time, even books, making it extremely efficient.
