Description

Technical Field

[0001] This utility model relates to the field of diamond crystal processing technology, and in particular to an adjustable diamond laser cutting fixture. Background Technology

[0002] When laser cutting diamonds, a special fixture is used to fix the diamond workpiece during the laser cutting process to prevent workpiece displacement and vibration, and to ensure that the laser cutting head can accurately act on the target position. Adjustable fixtures, through adjustable clamping components, can adapt to clamping workpieces of different sizes and shapes, making up for the lack of adaptability of traditional fixtures. Operators can quickly complete the adjustment of fixture parameters, shorten the workpiece clamping time, and are especially suitable for small-batch, multi-category diamond processing scenarios.

[0003] In some existing adjustable diamond laser cutting fixtures, the fixture is adjusted according to the specifications of the diamond workpiece to be processed. The clamping area is adapted to the shape of the workpiece, the diamond workpiece is placed stably in the positioning area of ​​the fixture, the clamping assembly is activated, and the clamping force and positioning position are finely adjusted to ensure that the workpiece is firmly fixed and without deformation. At the same time, the cutting part of the workpiece is aligned with the path reference of the laser cutting head. After clamping, the laser cutting equipment is activated to perform cutting.

[0004] In the field of diamond processing, some adjustable diamond laser cutting fixtures generally lack adjustment settings that balance rapid adjustment and force balance. For fixed fixtures of a single specification, when faced with diamonds of different shapes, the clamping surface cannot fully fit the contour of the workpiece, which easily leads to uneven force during clamping. This causes the fixture to tilt during movement, resulting in jamming and damage to the fixture, requiring frequent fixture replacement. Therefore, an adjustable diamond laser cutting fixture is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable diamond laser cutting fixture, which aims to improve the problem that some existing diamond laser cutting fixtures are not convenient for quickly adapting and adjusting the clamping to accommodate uneven forces on diamonds of different shapes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable diamond laser cutting fixture includes a fixture base, a plurality of protective shells fixedly connected to the top of the fixture base, a plurality of adjustable clamping mechanisms being provided inside the protective shells, a clamping plate being rotatably connected to the outside of the adjustable clamping mechanism, a quick-release mechanism being provided outside the clamping plate, and a clamping pad being fixedly connected to the outside of the clamping plate. The adjustable clamping mechanism includes a clamping bolt, the external thread of which is connected to the inside of the protective shell, a knob fixedly connected to one external end of the clamping bolt, a sliding plate slidably connected inside the protective shell, a force plate fixedly connected to the outside of the sliding plate, and a leveling component provided on the outside of the force plate. As a further description of the above technical solution: The quick-release mechanism includes a quick-release interface, which is rotatably connected to the outside of the leveling component. A quick-release connector is slidably connected to the outside of the quick-release interface, and a groove is provided on the outside of the quick-release connector.

As a further description of the above technical solution: An adjustment assembly is externally fixedly connected to the quick-release connector, and the quick-release connector is externally fixedly connected to the outside of the clamping plate. As a further description of the above technical solution: The adjustment assembly includes a telescopic spring, which is externally fixedly connected to the outside of the quick-release connector.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Example: Adjustable diamond laser cutting fixture, see reference Figures 1 to 3 The clamping mechanism includes a clamp base 1, which serves as the main support frame and provides a stable mounting foundation for the entire clamping mechanism. Multiple protective shells 2 are fixedly connected to the top of the clamp base 1. These protective shells 2 serve both protective and guiding functions, preventing cutting debris and laser reflection from damaging the clamping mechanism components. They also provide sliding guidance for the sliding plate 33 and the leveling rod 351, limiting their movement trajectory. Multiple adjustable clamping mechanisms 3 are housed inside the protective shells 2, and each adjustable clamping mechanism 3 is rotatably connected to a clamping device. The holding plate 4 is a clamping actuator that directly contacts the diamond. It can rotate to adapt to different angles of fixation requirements according to the shape of the diamond, while transmitting the clamping force of the adjustable clamping mechanism 3 to ensure stable fixation of the workpiece. The clamping plate 4 is externally equipped with a quick-release mechanism 5, and is externally fixedly connected with a clamping pad 6. The clamping pad 6 prevents excessive clamping force from scratching the diamond surface, while increasing the friction with the diamond to prevent the workpiece from shifting due to vibration during the cutting process. The adjustable clamping mechanism 3 includes clamping bolts. 31. The clamping bolt 31 converts the rotational motion of the knob 32 into axial thrust through threaded transmission, pushing the sliding plate 33 closer to the diamond workpiece to achieve clamping. The external thread of the clamping bolt 31 is connected to the inside of the protective shell 2. A knob 32 is fixedly connected to one end of the clamping bolt 31, providing the operator with a convenient point of force application. The clamping bolt 31 can be manually rotated to adjust its advance and retreat, facilitating quick and fine-tuning of the clamping force. The sliding plate 33 is slidably connected inside the protective shell 2, and the sliding plate 33 holds the clamping bolt 31 closer to the diamond workpiece. The axial thrust of 1 is transmitted to the force plate 34, which drives the clamping plate 4 to move synchronously to clamp the diamond. The force plate 34 is fixedly connected to the outside of the sliding plate 33. The force plate 34 evenly distributes the clamping force transmitted by the sliding plate 33 to avoid excessive local force on the diamond. On the other hand, it cooperates with the leveling component 35 to automatically compensate for the slight tilt of the clamping plate 4 through the elastic support of the leveling rod 351, ensuring that the clamping surface is flat and in contact with the diamond, and preventing the workpiece from chipping. The leveling component 35 is provided on the outside of the force plate 34. Specifically, when the staff is holding the diamond, they can adjust the length of the clamping bolt 31 by rotating the knob 32. The clamping bolt 31 pushes the force plate 34 to apply a thrust to the sliding plate 33. During the pushing process, the leveling component 35 can compensate for the force on the force plate 34.

[0013] The leveling component 35 compensates for clamping surface errors through elastic deformation, ensuring clamping flatness. The leveling component 35 includes a leveling rod 351. When the force plate 34 is tilted, the higher side of the leveling rod 351 compresses the return spring 353, while the lower side of the leveling rod 351, under the action of the spring, lifts the force plate 34, automatically correcting the flatness of the clamping surface. Simultaneously, it buffers the impact force during clamping, preventing rigid contact damage to the diamond surface. The exterior of the leveling rod 351 is in contact with the exterior of the force plate 34. A limiting plate 352 is fixedly connected to the exterior of the leveling rod 351. The limiting plate 352 restricts the compression range of the return spring 353, preventing excessive deformation and failure of the spring. Simultaneously, it slides along the limiting groove 354, ensuring that the leveling rod 351 moves only in the vertical direction, preventing deviation during leveling. A return spring 353 is externally connected to the leveling rod 351, providing upward support and ensuring that the leveling rod 351 is always in close contact with the force plate 34 for real-time leveling. Simultaneously, the return spring 353 pushes the leveling rod 351 back to its original position after the clamping force is removed. A limiting groove 354 is formed inside the protective shell 2, restricting the sliding direction of the limiting plate 352 through its groove wall. This ensures that the leveling rod 351 only moves vertically, preventing leveling failure due to tilting. The limiting plate 352 is slidably connected to the outside of the limiting groove 354. One end of the return spring 353 is fixedly connected to the outside of the limiting plate 352 and the inside of the protective shell 2. The leveling rod 351 is slidably connected to the inside of the protective shell 2. Specifically, when the force plate 34 moves forward, the force plate 34 separates from the leveling rod 351. At this time, the limiting plate 352 connected to the leveling rod 351 loses the pressure of the force plate 34. Under the elastic action of the return spring 353, the limiting plate 352 contracts, causing the limiting plate 352 and the leveling rod 351 to extend, compensating for the force on the force plate 34, so that the force plate 34 moves smoothly.

[0014] Reference Figure 1 , Figure 2 and Figure 4The quick-release mechanism 5 includes a quick-release interface 51, which receives power and performs leveling functions from the adjustable clamping mechanism 3. Furthermore, through insertion and removal of the quick-release connector 52, it enables quick docking of the clamping plate 4 and the sliding plate 33. The quick-release interface 51 is externally rotatably connected to the outside of the leveling assembly 35, and the quick-release connector 52 is externally slidably connected to the quick-release interface 51. The quick-release connector 52 serves as a transition connector between the clamping plate 4 and the quick-release interface 51, and through its cooperation with the quick-release interface 51, it stably fixes the clamping plate 4. The quick-release connector 52 is provided with a sliding groove 53 on its outside to ensure that there is no loosening during cutting. The sliding groove 53 provides a sliding track for the fixed telescopic rod 542, which restricts its movement to only in a direction perpendicular to the axis of the quick-release connector 52. This ensures that the fixed telescopic rod 542 can be locked into the locking position of the quick-release interface 51, and avoids displacement that may cause engagement failure. The quick-release connector 52 is fixedly connected to an adjustment component 54. The adjustment component 54 achieves automatic engagement and locking and convenient unlocking by pressing through elastic drive, which is a concrete manifestation of the quick-release function. Specifically, when the clamping plate 4 is damaged, the operator can use the adjustment component 54 to fix and unlock the quick-release connector 52. After unlocking, the operator will pull the clamping plate 4 connected to the quick-release connector 52 out of the quick-release interface 51.

[0015] The adjusting assembly 54 includes a telescopic spring 541. In its natural state, the telescopic spring 541 pushes the fixed telescopic rod 542 to extend towards the quick-release interface 51, causing it to engage with the locking groove of the quick-release interface 51, thus achieving automatic locking. When unlocking, it is compressed as the fixed telescopic rod 542 retracts, and quickly resets after being released, ensuring locking reliability. The telescopic spring 541 is externally fixedly connected to the outside of the quick-release connector 52, and the fixed telescopic rod 542 is externally fixedly connected to the outside of the telescopic spring 541. The fixed telescopic rod 542 restricts the axial separation of the quick-release interface 51 and the quick-release connector 52 through rigid contact between the rod body and the groove wall, rigidly fixing the clamping plate 4. When compressed, it retracts along the sliding groove 53, disengaging from the locking structure and achieving unlocking. The quick-release interface 51 slides externally. An adjusting rod 543 is connected. The adjusting rod 543 retracts the fixed telescopic rod 542 by pressing it from the bottom, thus unlocking it. Its sliding connection ensures that the pressing action is transmitted vertically, avoiding force deviation that would make unlocking difficult. Limiting blocks 544 are fixedly connected to both sides of the adjusting rod 543. The limiting blocks 544 limit the maximum pressing stroke of the adjusting rod 543, preventing excessive pressing that could damage the fixed telescopic rod 542 and the telescopic spring 541, while also preventing the adjusting rod 543 from falling out of the quick-release interface 51. The quick-release connector 52 is fixedly connected to the outside of the clamping plate 4. The top of the fixed telescopic rod 542 is in contact with the bottom of the adjusting rod 543. The outside of the fixed telescopic rod 542 is slidably connected to the outside of the slide groove 53. Specifically, when adjusting the adjustment component 54 to unlock the quick-release connector 52, the operator can press down the fixed telescopic rod 542, which is in the extended state, by pressing down the adjustment lever 543. During the pressing process, the telescopic spring 541 is compressed. When the fixed telescopic rod 542 moves down to the fixed position, the quick-release interface 51 and the quick-release connector 52 can be separated by pulling out the clamping plate 4.

[0016] The implementation principle of this application embodiment is as follows: When the worker needs to clamp the diamond, the diamond can first be placed in the middle of the clamp. At this time, the worker rotates the knob 32 to drive the clamping bolt 31 to extend. The extension of the clamping bolt 31 pushes the force plate 34 to move forward. During the pushing process, since the return spring 353 is initially in an extended state under the pressure of the force plate 34, after the force plate 34 moves forward, the force plate 34 disengages from the leveling rod 351. The limiting plate 352 connected to the leveling rod 351 loses its pressure effect. Under the elastic action of the return spring 353, the return spring 353 contracts, driving the limiting plate 352 and the leveling rod 351 to extend, compensating for the force on the force plate 34, so that the force plate 34 moves smoothly. The extension of the force plate 34 drives the sliding plate 33 and the clamping plate 4 to slide and extend together. During the extension, the clamping plate 4 can automatically adjust the angle according to the diamond surface to clamp diamonds of different shapes.

[0017] When the clamping plate 4 is damaged and needs to be replaced, the operator can press the adjusting lever 543 to press down the fixed telescopic rod 542, which is in the extended state. When pressed down, the telescopic spring 541 is compressed. When the fixed telescopic rod 542 moves to the fixed position, the clamping plate 4 can be pulled out, and the quick-release interface 51 and quick-release connector 52 are separated. When installing the clamping plate 4, the operator inserts the quick-release connector 52 into the quick-release interface 51. When fully inserted, the fixed telescopic rod 542 extends under the elastic action of the telescopic spring 541, so that the fixed telescopic rod 542 is inserted into the designated position of the quick-release interface 51, thereby realizing the quick installation and removal of the clamping plate 4.

[0018] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
