Abstract

The utility model relates to a displacement buffering device of a work seat for spectacle cutting machines, which is matched with an L-shaped connection rod on a cutting machine for implementation. A work seat is abutted on an idler wheel of the L-shaped connection rod. A buffering device is arranged on the corner side of the L-shaped connection rod. The utility model comprises an air cylinder, a pushing slide block, a propping head and a fixing seat, wherein the pushing slide block is connected with the air cylinder; the pushing slide block and the propping head are arranged in the fixing seat and are mutually and vertically arranged; the propping head is propped with regulation screws or a micrometer. When the utility model is used, the pushing slide block is propped with the propping head. Processing spectacles on the work seat are conveyed to a cutting head for first coarse cutting and processing. When the pushing slide block is backwards moved under the drive of the air cylinder, the propping head is lowered and the processing spectacles have further fine cutting, grinding and processing. The utility model is accurate and stable to position and can realize annular cutting for cutting forms.

Description

The displacement buffer unit of the work block of eyeglass cutter

Technical field

The utility model relates to a kind of displacement buffer unit of work block of eyeglass cutter.

Background technology

At present on the manufacturing process of eyeglass, process equipment comprises eyeglass anchor clamps and eyeglass topping machanism, being cut into twice of eyeglass, for the first time with the molded lenses of workprint cutting with the suitable size of print, cutting is for the second time then done further retrofit with the edge of molded lenses, comprises the shape that its edge is cut various requirements such as (mill) oblique shape face of one-tenth or triangled tip face.The eyeglass anchor clamps are arranged on the mobilizable work block usually, during cutting, on one side work block tilts to topping machanism, make processed eyeglass be positioned at the processing stations of topping machanism, and after cutting was finished, work block drove the eyeglass anchor clamps again and returns to original position.The cutting of oil pressure control with the buffering eyeglass adopted in the displacement of this work block, its weak point is, oil pressure is controlled to be at the uniform velocity mode, make the spiral carry of being cut into of eyeglass cut, when causing eyeglass rough lumber for the first time to cut, easily local excessive cutting, when making fine finishining for the second time, the cutting at this place (mill) effect is undesirable.

The utility model content

The purpose of this utility model is to provide a kind of displacement buffer unit of work block of eyeglass cutter, overcomes the excessive problem of eyeglass partial cut, and the cutting of eyeglass (mill) processing is more accurate, and effect is even more ideal.

For achieving the above object, the utility model provides following technical scheme:

The displacement buffer unit of the work block of eyeglass cutter, cooperate the L type connecting rod on the cutter to implement, work block is resisted against on the roller of L type connecting rod, buffer unit is arranged on the arm of angle of L type connecting rod, comprise cylinder, promote slide block, top and holder, described promotion slide block is connected with cylinder rod, promotes slide block and top and is built in the holder, and vertically setting, inclined-plane contact mutually, and push up mutually with set screw or micrometer the top.

The above-mentioned promotion slide block and the link of cylinder are provided with clip slot, and the head of connecting screw is embedded in the clip slot, and the other end is fixed on the cylinder.

Said structure provides the buffer unit of a work block displacement for cutter, when the promotion slide block travels forward under cylinder action, the top of inclined-plane contact is by the jack-up that makes progress with it, hold mutually with the set screw of upper end, before machining lens on the work block is sent to cutting head, carries out the rough lumber first time and cut processing; When mobile backward, the top descends under promoting the drive of slide block at cylinder, and the arm of angle pressure of L type connecting rod reduces, because work block is resisted against on the roller of L type side rod, make it to travel forward with work block, machining lens continues near cutting head, further carries out meticulous cutting mill processing.Owing to adopt above-mentioned promotion slide block to be connected with the inclined-plane, top, the active force that gives L type connecting rod is slowly, a buffering is fully arranged when making cut-off lens near cutting head, directly enter second cleavage, cutting accurate positioning, stable, cutting mode can be realized the annular cutting, rather than existing spiral cutting; And above-mentioned promotion slide block adopts the inclined-plane contact with the top, makes in the motion process, and it is big to come directly towards contact-making surface, can stablize uplink and downlink.

The specific embodiment

As Figure 1-3, the utility model provides a kind of buffer unit of eyeglass formula cutter, comprise cylinder (not looking among the figure), promotion slide block 2, holder 3, top 4 and base 5, cylinder rod 6 in the cylinder is connected by a connecting screw 7 with promotion slide block 2, one end of connecting screw 7 is fixed on the cylinder rod 6, and the other end is embedded in the clip slot 21 that promotes slip 2; Promote slide block 2 and be built in the through hole 31 of holder 3, the upper surface that promotes slide block 2 is downward-sloping to the other end from cylinder one end, and the lower surface of top 4 is the inclined-plane, matches with the upper surface that promotes slide block 2; Also be provided with in the holder 3 one with the orthogonal slotted eye 32 of through hole, promoting slide block 2 can move forward and backward horizontal through hole 31 in, comes directly towards 4 and is built in longitudinally in the slotted eye 32, its lower surface contacts with the inclined-plane, upper surface of promotion slide block 2.

As shown in Figure 4, with the buffer unit that above-mentioned assembling is finished, be fixedly mounted on the cutter 8, cutter 8 is provided with the work block 9 and the topping machanism of band eyeglass anchor clamps, work block 9 is provided with an extension spring (not looking among the figure) and links to each other with base, so that work block 9 is realized running fix.Device L type connecting rod 10 is arranged on the supporting seat 11, and the eyeglass fixed axis 91 on its roller 101 and the cutter work block 9 offsets, and this work block 9 serves as the axle swing with alignment pin 102, and buffer unit is placed on the arm of angle 103 of L type connecting rod 10; The base of cutter 8 is provided with a set screw bearing 12, and bearing 12 is provided with micrometer 13, and push up mutually with top 4 lower end of micrometer 13.

During use, anchor clamps 14 1 ends on the work block 9 are fixed with the eyeglass sample, and the other end is placed machining lens by manipulator 15.When promoting slide block 2 and travel forward with cylinder, the top 4 of inclined-plane contact is by the jack-up that makes progress with it, hold mutually with the micrometer 13 of upper end, because set screw 13 is fixed on the set screw bearing 12, holding down, this buffer unit imposes a downward active force to the arm of angle of L type connecting rod 10, make L type connecting rod 10 move backward, promotion is positioned at first working position against the work block 9 on it, be the outer shroud cutting of eyeglass, before the machining lens on the work block 9 was sent to high-speed cutting 81, cutting head 81 was aimed at eyeglass lateral margin central authorities and is done cutting movement, realize roughing, as shown in Figure 5; Under promoting the drive of slide block 2 when mobile backward at cylinder, top 4 descends, the pressure that is applied on L type connecting rod 10 arms of angle reduces, and L type connecting rod 10 moves forward, and work block 9 travels forward thereupon, further near high-speed cutting 81, directly be positioned at second machining position, promptly the interior ring cutting of eyeglass cuts, before machining lens is sent to cutting head 81, realize the meticulous mill processing of cutting, as shown in Figure 6.
