Description

Technical Field

[0001] The present invention relates to quartz processing technology, and more particularly to a universal positioning device for quartz processing. Background Art

[0002] During the processing of quartz products, clamping and positioning are required. Currently, the commonly used clamping and positioning methods are mainly vacuum adsorption positioning and wax sticking positioning. Since the vacuum adsorption method cannot achieve universality, a fixture needs to be designed and made separately for each product. The wax sticking positioning method wastes a long time of auxiliary work, and requires heating, wax sticking, cooling and other processes. In addition, the operation needs to be repeated after the quartz product is processed, which is relatively inefficient. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention provides a universal positioning device for quartz processing, which can realize the clamping and positioning of quartz products of different shapes, has good versatility, and high efficiency in clamping and positioning quartz products.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a universal positioning device for quartz processing, comprising a positioning plate installed on a workbench, a plurality of adjustable positioning blocks that can slide and rotate are connected at intervals on the positioning plate, a quartz product is loaded on the positioning plate, and the adjustable positioning blocks are close to the periphery of the quartz product to realize the clamping and positioning of the quartz product.

[0005] When clamping the quartz product, load the quartz product onto the positioning plate, and then adjust the position of the positioning block according to the shape of the quartz product. The positioning block is adjusted by sliding and rotating to make it close to the periphery of the quartz product, thereby achieving the clamping and positioning of the quartz product. Since the positioning block can slide and rotate, the position can be adjusted to accommodate quartz products of different shapes and specifications. By adjusting the position of the positioning block to close to the periphery of the quartz product for clamping and positioning, the time for designing and making a separate fixture for vacuum adsorption positioning is saved, and the time for heating, waxing, cooling and other processes of wax sticking positioning is saved.

[0006] The universal positioning device for quartz processing of the present application can realize the clamping and positioning of quartz products of different shapes, has good versatility, and has high efficiency in clamping and positioning quartz products.

[0007] Preferably, the adjusting positioning block is connected to a locking screw, and the locking screw is fastened to the workbench.

[0008] Before tightening the locking screw, adjust the adjusting positioning block into place. After tightening the locking screw, the adjusting positioning block is locked and positioned, so that the adjusting positioning block, the positioning plate and the workbench are firmly connected together.

[0009] Preferably, a plurality of T-slots are arranged on the workbench, and fastening blocks are arranged on the workbench corresponding to the adjustment and positioning blocks. The fastening blocks are slidably inserted in the T-slots, and the locking screws are fastened to the fastening blocks.

[0010] The T-slot limits the fastening block so that it can only slide horizontally in the T-slot but cannot vertically leave the T-slot. The locking screw is connected to the fastening block installed on the workbench, which is convenient to connect. The fastening block can be moved, which is convenient for adjusting the connection position, thereby realizing the adjustment of the positioning plate and the positioning block position.

[0011] Preferably, the adjusting positioning block is provided with an adjusting long slot, and the locking screw passes through the adjusting long slot.

[0012] The setting of the adjusting long slot is convenient for adjusting the position of the positioning block.

[0013] Preferably, connecting long grooves are provided on the positioning plate and on the adjusting positioning block correspondingly, and the locking screw passes through the connecting long grooves.

[0014] The long connecting groove facilitates the adjustment of the position when the positioning plate is connected to the workbench.

[0015] Preferably, a supporting boss is provided on the adjusting positioning block.

[0016] The support boss can improve the structural strength of the adjustment block and avoid deformation of the adjustment block after the locking screw is connected to the adjustment block. In addition, the support boss protrudes upward. After the adjustment block is turned over, the support boss is supported on the positioning plate. At this time, the height of the two ends of the adjustment block is increased, and the two ends of the adjustment block are positioned against the periphery of the quartz product, which can adapt to the clamping and positioning of thicker quartz products.

[0017] In the second solution, a clamping head is provided on the adjusting and positioning block, the clamping head is detachably connected to the adjusting and positioning block, and the clamping head is clamped to the periphery of the quartz product.

[0018] The clamping head can be detachably connected to the adjustment and positioning block. The clamping head suitable for quartz products of different shapes and sizes can be replaced and connected to the adjustment and positioning block, making the clamping and positioning more accurate and reliable.

[0019] In a third solution, a rotatable universal clamping head is arranged on the adjusting and positioning block, and a plurality of clamping surfaces of different shapes are arranged at intervals along the circumference of the edge of the universal clamping head.

[0020] The edge of the universal clamping head is provided with multiple clamping surfaces of different shapes to adapt to the clamping of quartz products of various shapes. It is only necessary to rotate the universal clamping head to align the clamping surface matching the quartz product with the quartz product. The setting of the universal clamping head greatly improves the versatility of the entire clamping device.

[0021] The fourth solution is to set a number of adaptive pin headers arranged at intervals at the end of the adjusting positioning block, install a buffer spring between the adaptive pin header and the adjusting positioning block, install a pressure strip on the adjusting positioning block, and connect positioning screws on the pressure strip and corresponding to the adaptive pin header. The end of the positioning screw can abut against the adaptive pin header to position the adaptive pin header.

[0022] The quartz product is loaded onto the positioning plate. During the adjustment of the positioning block, the end of the adaptive pin header is close to the outer wall of the quartz product, so that the contour shape formed by the ends of all adaptive pin headers is adapted to the outer wall of the quartz product. Then the positioning screws on the pressure strip are tightened to achieve the locking and positioning of the adaptive pin header. At this time, the adaptive pin header on the positioning block is fully adapted to the quartz product, and the clamping and positioning are reliable. By setting the adaptive pin header to adapt to quartz products of different shapes and specifications, it has good versatility.

[0023] The fifth solution is to set a movable clamping block at the end of the adjusting positioning block, connect a tension spring between the clamping block and the adjusting positioning block, install a cam on the adjusting positioning block, the outer wall of the cam is close to the clamping block, and the rotation of the cam drives the clamping block to move.

[0024] The clamping block can buffer movement and achieve clamping and positioning after it is close to the outer wall of the quartz product. Before the quartz product is clamped to the positioning plate, the cam is rotated to make the clamping block retract under the action of the tension spring. At this time, the space surrounded by all the clamping blocks is larger than the outline size of the quartz product, and the quartz product can be easily installed on the positioning plate. After the quartz product is transferred to the right place, the cam rotates to push the clamping block outward and close to the outer wall of the quartz product to achieve the clamping and positioning of the quartz product. The cam is locked after it is rotated into place. When the quartz product is processed and unloaded, the cam is rotated to make the clamping block retract under the action of the tension spring, and the quartz product is released, so that the quartz product can be easily removed. In the actual operation process, in many cases, it is only necessary to rotate the cam on one of the adjustment and positioning blocks to achieve the movement of the clamping block, so that the quartz product can be easily clamped, positioned, released and removed.

[0025] Compared with the prior art, the present invention has the following beneficial effects: (1) the universal positioning device for quartz processing can realize the clamping and positioning of quartz products of different shapes, has good versatility, and has high efficiency in clamping and positioning quartz products; (2) the adjustment of the positioning block for clamping and positioning the quartz product has a good matching degree, and the clamping is accurate and reliable.

A tensioning spring 22 is connected between the clamping block 21 and the adjusting and positioning block 3. A cam 23 is installed on the adjusting and positioning block 3. The outer wall of the cam 23 is against the clamping block 21. The cam 23 rotates to push the clamping block 21 to move. Two plug posts 24 are provided on the clamping block 21. Sockets 25 are provided on the adjusting and positioning block 3 corresponding to the plug posts 24. The plug posts 24 and the sockets 25 are adapted for insertion. The tensioning spring 22 is installed in the sockets 25. The tensioning spring 22 is connected between the plug posts 24 and the sockets 25. A limit screw is provided on the adjusting and positioning block 3 corresponding to the cam 23. After the cam 23 rotates into place, the limit screw is tightened. The limit screw abuts against the cam 23 to achieve positioning and locking of the cam 23.

[0059] The clamping block 21 can buffer the movement and realize the clamping and positioning after it is close to the outer wall of the quartz product 4. Before the quartz product 4 is clamped to the positioning plate 2, the cam 23 is rotated to make the clamping block 21 retract under the action of the tension spring 22. At this time, the space surrounded by all the clamping blocks 21 is larger than the outline size of the quartz product 4, and the quartz product 4 can be easily mounted on the positioning plate 2. After the quartz product 4 is transferred to the position, the cam 23 rotates to push the clamping block 21 to extend outward and close to the outer wall of the quartz product 4 to realize the clamping and positioning of the quartz product 4. After the cam 23 is rotated to the position, the cam 23 is locked. When the quartz product 4 is processed and unloaded, the cam 23 is rotated to make the clamping block 21 retract under the action of the tension spring 22, and the quartz product 4 is released, so that the quartz product 4 can be easily removed. In the actual operation process, in many cases, it is only necessary to rotate the cam 23 on one of the adjustment and positioning blocks 3 to realize the movement of the clamping block 21, so that the clamping and positioning of the quartz product 4 can be easily realized and released.

[0060] When the quartz product 4 is clamped, the quartz product 4 is loaded onto the positioning plate 2, and then the position of the positioning block 3 is adjusted according to the shape of the quartz product 4. The positioning block 3 is adjusted by sliding and rotating to adjust the position so that the clamping block 21 on the positioning block 3 is close to the periphery of the quartz product 4, thereby achieving the clamping and positioning of the quartz product 4. Since the positioning block 3 can slide and rotate, the position adjustment can be achieved to adapt to quartz products 4 of different shapes and specifications. By adjusting the position of the positioning block 3 so that the clamping block 21 is close to the periphery of the quartz product 4 for clamping and positioning, the time for designing and making a separate fixture for vacuum adsorption positioning is saved, and the time for heating, waxing, cooling and other processes of the wax sticking positioning method is saved.
