Description

Technical Field

[0001] The utility model relates to the technical field of gear processing devices, in particular to a punching device used for high-strength gear processing. Background Art

[0002] High-strength gears refer to mechanical components with teeth on the rim that can continuously engage with high strength to transmit motion and power. High-strength gears need to be punched on the outside during processing. The outside of high-strength gears needs to be punched at multiple points. When the existing punching machine is used, after punching a hole in one part of the gear, it is necessary to drive the punching machine to punch in other directions after displacement, which leads to a decrease in the punching speed. At the same time, after the position of the punching machine is changed, the position of the punching machine needs to be corrected, which increases the processing steps and reduces the processing speed. Utility Model Content

At the same time, after the position of the punch is changed, the position of the punch needs to be corrected, which increases the processing steps and reduces the processing speed.

[0005] (2) Technical solution

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a punching device for high-strength gear processing, comprising: a frame, a hydraulic rod, a puncher, and a load-bearing plate, wherein the hydraulic rod is assembled on the top of the frame, the puncher is assembled on the front of the hydraulic rod, the load-bearing plate is assembled on the top of the frame, the top of the load-bearing plate is equipped with a workbench, the top of the workbench is connected to a three-jaw chuck group, and the outside of the three-jaw chuck group is equipped with a rotating mechanism.

[0007] The rotating mechanism includes a worm wheel and a hollow gear. The worm wheel is assembled at the bottom of the three-jaw chuck group. The back of the worm wheel is meshed with a worm. Both ends of the worm are sleeved with ratchets. The inner top of the hollow gear is connected to a pawl through a spring hinge, and the back of the hollow gear is meshed with a toothed plate.

[0008] Preferably, the outside of the tooth plate is connected to a slider, and the outside of the slider is slidably connected to a slotted block, and the slotted block is assembled on the top of the workbench.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 , a punching device for high-strength gear processing, comprising: a frame 1, a hydraulic rod 2, a puncher 3, and a load-bearing plate 4. This scheme is a structural improvement of the non-electronic component part on the basis of the punching device for high-strength gear processing in the prior art, wherein the frame 1, hydraulic rod 2, puncher 3, and load-bearing plate 4 are the common high-strength gear processing punching products that have been promoted in the prior art. The frame 1 can support the hydraulic rod 2, and the hydraulic rod 2 can drive the puncher 3 to rise and fall, and the puncher 3 can punch holes in the gear, and the load-bearing plate 4 can assemble the workbench 5. The hydraulic rod 2 is assembled on the top of the frame 1, the puncher 3 is assembled on the front of the hydraulic rod 2, and the load-bearing plate 4 is assembled on the top of the frame 1. The top of the load-bearing plate 4 is equipped with a workbench 5, and the top of the workbench 5 is connected with a three-jaw chuck group 6. The three-jaw chuck group 6 is a common three-jaw chuck in the prior art, which can fix the gear.

[0023] See also Figure 3 and Figure 4 The outside of the three-jaw chuck group 6 is equipped with a rotating mechanism 7, which includes a worm gear 71 and a hollow gear 75. The worm gear 71 can drive the worm 73 to rotate, and the hollow gear 75 can be driven to rotate by the tooth plate 77. The worm gear 71 is assembled at the bottom of the three-jaw chuck group 6, and the back of the worm gear 71 is meshed with the worm 73. Both ends of the worm 73 are socketed with ratchets 74. The ratchet 74 can drive the worm 73 to rotate. The inner top of the hollow gear 75 is connected to a pawl 76 through a spring hinge, and the pawl 76 can drive the ratchet 74 to rotate.

[0024] The back of the hollow gear 75 is meshed with a tooth plate 77, which can drive the hollow gear 75 to rotate. The cooperation of the hollow gear 75, the ratchet 74 and the pawl 76 ensures that the tooth plate 77 can drive the worm 73 to rotate 60° only when it descends. The worm 73 will not rotate when the tooth plate 77 returns to its original position. A slider 772 is connected to the outside of the tooth plate 77.

[0025] The external sliding connection of the slider 772 is connected to a slotted block 771, and the slotted block 771 is assembled on the top of the workbench 5. A return spring 773 is connected between the slider 772 and the slotted block 771. The slotted block 771 cooperates with the slider 772 to guide the tooth plate 77 to move linearly, and the return spring 773 can drive the tooth plate 77 to return after movement.

[0026] The inside of the worm wheel 71 is equipped with a short shaft 72, and the bottom of the short shaft 72 is connected to the top of the workbench 5 through a seat bearing. The short shaft 72 can support the worm wheel 71. The outside of the worm 73 is connected to an assembly plate 731 through a seat bearing. The assembly plate 731 is connected to the workbench 5, and the assembly plate 731 can support the worm 73.

[0027] The tooth plate 77 includes a vertical plate, and teeth are evenly distributed on the front of the vertical plate. The teeth on the outside of the tooth plate 77 can drive the hollow gear 75 to rotate when it descends. At the same time, after the teeth finish engaging with the hollow gear 75, the tooth plate 77 cannot drive the hollow gear 75 to rotate when it descends again, thereby preventing the gear from continuing to rotate during drilling. A spherical bearing 78 is sleeved on the outside of the hollow gear 75, and the spherical bearing 78 is connected to the workbench 5. The spherical bearing 78 can support the hollow gear 75.

[0028] In this solution, the gear is first placed on the top of the three-jaw chuck group 6, the three-jaw chuck group 6 is started to fix the gear, the hydraulic rod 2 is started to drive the punch 3 to descend, the punch 3 is started to punch the gear, and the punch 3 returns to its original position after the punching is completed, and then descends again to prepare for punching in other directions. At the same time, the punch 3 drives the toothed plate 77 to descend when it descends, and then drives the meshing hollow gear 75 to rotate, and then drives the pawl 76 to drive the ratchet 74 to rotate, and then drives the worm 73 to rotate, and finally drives the worm wheel 71 to rotate. The rotating worm wheel 71 drives the three-jaw chuck group 6 to rotate 60 degrees;

[0029] When the top of the gear is being punched, the additional rotating mechanism 7 automatically moves when the punch 3 returns to its position and descends again, and then drives the three-jaw chuck group 6 to rotate. There is no need to adjust the position of the punch 3 and then perform correction to punch the gear, thereby increasing the speed of the gear punching process. At the same time, the self-locking characteristics of the worm 73 and the worm wheel 71 are utilized, and after the position of the three-jaw chuck group 6 is adjusted, the position of the three-jaw chuck group 6 is automatically self-locked, thereby avoiding drilling failure caused by rotational deviation of the gear during drilling.
