Description

Technical Field

[0001] The present application relates to the field of laser cutting technology, and in particular to a laser cutting platform fixing device and clamping device. Background Art

[0002] Laser cutting is an efficient and precise material cutting technology that uses a high-energy laser beam as a cutting tool. The focused laser beam is irradiated onto the material, causing the material to melt and evaporate quickly, ultimately achieving the cutting purpose. During the laser cutting process, the workpiece to be processed needs to be fixed on the cutting platform to ensure the cutting accuracy and stability.

[0003] In the related technology, a laser cutting fixture is designed, which includes a base, on which a group of movable rods that can approach each other are slidably provided, each movable rod is slidably provided with a group of clamping blocks, and the movable rods are rotatably provided with bidirectional threaded rods that drive the clamping blocks to approach each other; when the workpiece is fixed and clamped, the workpiece is placed between the movable rods, and the movable rods are driven to approach each other, and then the bidirectional threaded rods on the two movable rods are rotated respectively, so that each group of clamping blocks are approached to each other, and the two ends of the workpiece are clamped and fixed by the clamping blocks.

[0004] In the process of implementing this application, it was found that there are at least the following problems in this technology: in the process of clamping the workpiece, it is necessary to drive the moving rod closer and then rotate the two bidirectional threaded rods separately. The whole clamping process is relatively cumbersome, which affects the clamping efficiency. Utility Model Content

[0005] In order to facilitate the rapid clamping and fixing of the workpiece, simplify the clamping operation steps, and improve the clamping efficiency, the present application provides a laser cutting platform fixing clamping device.

[0006] The present application provides a laser cutting platform fixing device that adopts the following technical solution:

[0007] A laser cutting platform fixed clamping device includes a base, a group of moving rods are slidably arranged on the base, a clamping block is fixedly arranged on the moving rod, two rotating shafts are rotatably arranged in the clamping block, clamping claws and gears are fixedly arranged on the rotating shaft, a sliding groove is opened in the clamping block, the sliding groove is arranged between a group of gears, a sliding rod is slidably arranged in the sliding groove, one end of the sliding rod is exposed from the moving rod and an abutment plate is fixedly arranged, racks are arranged on both sides of the sliding rod, one of the gears is meshed with one of the racks, and the other gear is meshed with the other rack.

[0008] By adopting the above technical scheme, when the workpiece is fixed and clamped, the workpiece is placed between the moving rods, and then the moving rods are driven to approach each other until the abutment plate begins to abut the side wall of the workpiece. As the two moving rods continue to slide closer, the workpiece drives the sliding rod to slide to the bottom of the sliding groove by abutting the abutment plate. During the sliding process of the sliding rod, the rack and the gear are engaged with each other to drive the gear to rotate. The clamping jaw is connected to the gear through the rotating shaft and rotates with the gear, so as to clamp the workpiece between the clamping jaws. Throughout the entire clamping process, it is only necessary to drive the moving rod to slide, which is convenient for quickly clamping and fixing the workpiece, simplifying the clamping operation steps, and improving the clamping efficiency.

[0009] Preferably, two clamps are fixedly provided on each rotating shaft, wherein one clamp is fixedly provided at one end of the rotating shaft, and the other clamp is fixedly provided at the other end of the rotating shaft, and the gear is fixedly provided at the center of the rotating shaft.

[0010] By adopting the above technical solution, on the one hand, the clamping jaws, the abutment plate and the sliding rod are staggered, thereby minimizing the interference of the clamping jaws on the sliding of the abutment plate and the sliding rod. On the other hand, the clamping area of ​​the clamping jaws on the workpiece is increased, and the points of action of the clamping jaws on the workpiece are dispersed, thereby improving the stability of the workpiece clamping.

[0011] Preferably, a rubber pad is fixedly provided on the end of the clamping jaw.

[0012] By adopting the above technical solution, the clamping jaws are driven to approach the workpiece and clamp the workpiece, so that the workpiece needs to slide between the clamping jaws. At the moment when the clamping jaws contact the workpiece, the rubber pad plays a buffering role, thereby minimizing the friction between the clamping jaws and the workpiece surface and damaging the workpiece.

[0013] Preferably, a return spring is provided between the bottom wall of the sliding groove and the sliding rod, and the return spring drives the sliding rod away from the bottom wall of the sliding groove.

[0014] By adopting the above technical solution, when the two moving rods are driven away from each other, the reset spring has a tendency to recover and drives the sliding rod away from the bottom wall of the sliding groove. During this process, the rack meshes with the gear to drive the clamping claw to open.

[0015] Preferably, one end of the return spring is fixedly connected to the bottom wall of the sliding groove, and the other end of the return spring is fixedly connected to the sliding rod.

[0016] By adopting the above technical solution, the return spring connects the sliding rod and the bottom wall of the sliding groove, limiting the sliding rod to slide only in the sliding groove.

[0017] Preferably, the sliding rod is provided with a plurality of locking grooves, and a side wall of the locking groove close to the abutment plate is inclined to be a first inclined surface, and the clamping block is provided with a locking rod groove connected to the sliding groove, and a locking rod is slidably arranged in the locking rod groove, and the bottom end of the locking rod can be inserted into the locking groove, and the bottom end of the locking rod is provided with a second inclined surface that can contact the first inclined surface.

[0018] By adopting the above technical solution, in the process of the sliding rod sliding toward the bottom of the sliding groove, the first inclined surface contacts the second inclined surface, the locking rod is pushed open, and the sliding rod can slide toward the bottom of the sliding groove. When the sliding rod slides away from the bottom of the sliding groove, the bottom of the locking rod and the locking groove parking space ratio are offset, preventing the sliding rod from sliding away from the bottom of the sliding groove, so that the clamp cannot naturally release the workpiece, thereby ensuring the stability and reliability of the clamp in clamping the workpiece.

[0019] Preferably, a support frame is fixedly provided on the clamping block, a rotating rod is rotatably provided on the support frame, a movable connecting block is rotatably provided on one end of the rotating rod, the movable connecting block is rotatably connected to the end of the locking rod, a shift block is provided at the other end of the rotating rod, and a torsion spring is provided at the rotation connection between the rotating rod and the support frame, and the torsion spring drives the locking rod to approach the locking groove.

[0020] By adopting the above technical solution, when it is necessary to drive the locking rod out of the locking groove, press the shift block, the rotating rod rotates around the support frame, and the locking rod is lifted. When the shift rod is released, the torsion spring drives the locking rod to insert into the locking groove, thereby ensuring the abutment state between the locking rod and the locking groove.

[0021] Preferably, a restraining block is fixedly provided on the clamping block, a restraining groove is provided on a side wall of the restraining block, the shifting block is slidably provided on the rotating rod, and the shifting block can be inserted into the restraining groove and abut against the top wall of the restraining groove.

[0022] By adopting the above technical solution, when it is necessary to keep the locking rod lifted, press the shift block and make the shift block face the binding groove, then shift the shift block so that the shift block slides at the end of the rotating rod and inserts into the binding groove, thereby preventing the torsion spring from driving the rotating rod to rotate, so that the locking rod remains lifted.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the moving rod, clamping block, rotating shaft, clamping claw, gear, sliding groove, sliding rod, abutment plate, rack, rubber pad and reset spring, it is only necessary to drive the moving rod to slide during the clamping process, so as to quickly clamp and fix the workpiece, simplify the clamping operation steps and improve the clamping efficiency;

[0025] 2. By setting the locking groove, the first inclined surface, the locking rod groove, the locking rod and the second inclined surface, the sliding rod is restricted from sliding freely in the sliding groove, so that the clamping jaw cannot naturally release the workpiece, thereby ensuring the stability and reliability of the clamping jaw clamping the workpiece;

[0026] 3. By arranging the support frame, the rotating rod, the shifting block, the torsion spring, the restraining block and the restraining groove, it is convenient to control the locking rod to maintain the lifting and lowering state for a long time, and it is further convenient to control the clamping and releasing of the clamping claw.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a laser cutting platform fixing device. Figures 1 to 3, which comprises a base 1, on which a group of moving rods 11 that can move closer to or away from each other are slidably arranged, and a clamping block 2 is fixedly arranged on the top. Two rotating shafts 21 are rotatably arranged in the clamping block 2, and clamping claws 211 are fixedly arranged at both ends of the rotating shaft 21. Rubber pads 2111 are fixedly arranged at the ends of the clamping claws 211. The clamping claws 211 arranged on the two rotating shafts 21 can move closer to each other correspondingly, and a gear 212 for driving the rotating shaft 21 to rotate is fixedly arranged at the center of the rotating shaft 21. A sliding groove 22 arranged between the gears 212 is opened in the clamping block 2, and a sliding rod 23 is slidably arranged in the sliding groove 22. One end of the sliding rod 23 is exposed from the moving rod 11 and is fixedly provided with an abutment plate 231, and the other end of the sliding rod 23 is fixedly provided with a return spring 221 fixedly connected to the bottom wall of the sliding groove 22, and the return spring 221 drives the sliding rod 23 away from the bottom wall of the sliding groove 22. Racks 232 meshing with the gear 212 are provided on the upper and lower sides of the sliding rod 23 .

[0033] Reference Figures 1 to 3 During operation, the workpiece is placed between the moving rods 11. By driving the moving rods 11 closer to each other, the abutment plate 231 makes preliminary contact with the side wall of the workpiece. As the moving rods 11 continue to approach, the workpiece drives the sliding rod 23 to slide toward the bottom of the sliding groove 22 through the abutment plate 231. During the sliding process, the rack 232 and the gear 212 are meshed with each other to drive the gear 212 to rotate, and the rotation shaft 21 rotates to drive the jaws 211 to clamp the workpiece. When the jaws 211 need to be released, the moving rods 11 are driven away from each other, the return spring 221 drives the sliding groove 22 to slide outside, and the rack 232 and the gear 212 are meshed with each other to drive the jaws 211 to open. Two jaws 211 are provided on each rotating shaft 21, and a rubber pad 2111 is fixedly provided at the end of the jaw 211. Such a setting can increase the contact area between the jaw 211 and the workpiece and improve the stability of clamping. At the same time, the rubber pad 2111 can play a buffering role when the clamping jaw 211 clamps the workpiece, and try to avoid damage to the workpiece. During the entire clamping process, it is only necessary to drive the moving rod 11 to slide, which is convenient for quickly clamping and fixing the workpiece, simplifying the clamping operation steps and improving the clamping efficiency.

[0034] In order to ensure the stability and reliability of the clamping jaw 211, refer to Figure 2 and Figure 3The sliding rod 23 is provided with a plurality of locking grooves 233. A side wall of the locking groove 233 close to the abutting plate 231 is inclined to form a first inclined surface 2331. A locking rod groove 24 connected to the sliding groove 22 is vertically provided on the clamping block. A locking rod 241 is slidably provided in the locking rod groove 24. The bottom end of the locking rod 241 can be inserted into the locking groove 233. The bottom end of the locking rod 241 is provided with a second inclined surface 2411 that can contact the first inclined surface 2331. A support frame 25 is fixedly provided on the clamping block. A rotating rod 251 is rotatably provided on the support frame 25. A movable connecting block 2513 is rotatably provided at one end of the rotating rod 251. The movable connecting block 2513 is rotatably connected to the end of the locking rod 241. A shifting block 2511 is provided at the other end of the rotating rod 251. A torsion spring is provided at the rotation connection between the rotating rod 251 and the supporting frame 25. The torsion spring drives the locking rod 241 to approach the locking groove 233.

[0035] Reference Figure 2 and Figure 3 When the sliding rod 23 slides toward the bottom of the sliding groove 22, the first inclined surface 2331 contacts the second inclined surface 2411, driving the locking rod 241 to lift up to overcome the force of the torsion spring. When the sliding rod 23 slides out of the sliding groove 22, the locking rod 241 abuts against the locking groove 233 to limit the sliding of the sliding rod 23, thereby realizing the automatic locking operation of the sliding rod 23. When contact locking is required, the shifting block 2511 is pressed, and the rotating rod 251 drives the locking rod 241 to lift up away from the locking groove 233, thereby realizing the unlocking operation of the sliding rod 23.

[0036] In order to maintain the unlocked state of the sliding rod 23, refer to Figure 2 and Figure 3 The clamping block is fixedly provided with a restraining block 26, and a restraining groove 261 is provided on the side wall of the restraining block 26. The shifting block 2511 is slidably provided on the rotating rod 251, and the shifting block 2511 can be inserted into the restraining groove 261 and abut against the top wall of the restraining groove 261. The arrangement of the restraining block 26 and the restraining groove 261 allows the shifting block 2511 to be slidably inserted into the restraining groove 261 to prevent the locking rod 241 from rotating after the shifting block 2511 is pressed when the locking rod 241 needs to be kept in the lifted state. This facilitates the operator to free both hands and keep the sliding rod 23 unlocked.

[0037] The implementation principle of a laser cutting platform fixing and clamping device in an embodiment of the present application is as follows: during operation, the workpiece is placed between the moving rods 11. By driving the moving rods 11 to approach each other, the abutment plate 231 makes initial contact with the side wall of the workpiece. As the moving rods 11 continue to approach, the workpiece drives the sliding rod 23 to slide toward the bottom of the sliding groove 22 through the abutment plate 231. During the sliding process, the rack 232 and the gear 212 engage with each other to drive the gear 212 to rotate, and the rotation of the rotating shaft 21 drives the clamping jaw 211 to clamp the workpiece. The locking rod 241 is automatically inserted into the corresponding locking groove 233 to prevent the free sliding of the slide, and the clamping jaw 211 remains clamped. During the entire clamping process, it is only necessary to drive the moving rod 11 to slide, which is convenient for quickly achieving the clamping and fixing of the workpiece, simplifying the clamping operation steps, and improving the clamping efficiency.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
