Its transmission ratio is accurate, the efficiency is high, the structure is compact, the work is reliable, and the service life is long. During the production of gears, it is necessary to punch holes in the gears.

[0003] After patent retrieval, it is found that a punching device for main transmission gear processing with the publication number of CN 213729461U uses a second electro-hydraulic push rod to push the arc plate and the second rubber pad and the clamping cone fixed on the arc plate, inserts the clamping cone between the teeth of the gear, and makes the second rubber pad contact the tooth tip to fix the gear, preventing the gear from slipping and damaging the teeth. However, the arc plate, the second rubber pad and the clamping cone fixed on the arc plate are not replaceable, and the compatibility is poor when facing gears with different tooth ratios or gears with special-shaped teeth. Therefore, the utility model provides a punching device for transmission gears to improve the above problems. Summary of the Utility Model

[0025] The following further describes the present invention with reference to the embodiments.

[0026] Embodiment

[0027] An opening device for a transmission gear in this embodiment, as Figures 1-4As shown in the figure, it includes a workbench 1. The four corners of the workbench 1 are rounded to prevent harm to the user. At the same time, the top area of the workbench 1 is relatively large, which can prevent the gears to be processed or place the processed gears, improving work efficiency. A slot is provided in the center of the workbench 1. The support feet 3 pass through the workbench 1 and are fixed to the bottom of the top plate 2. The workbench 1 is fixed on the surface of the support feet 3. An electric telescopic rod 4 is fixed on the top of the top plate 2. A part of the electric telescopic rod 4 passes through the top plate 2. A fixed block 5 is fixed to the bottom surface of the electric telescopic rod 4. A motor 6 is fixed to the bottom of the fixed block 5. A cutter head 7 is installed at the bottom of the motor 6. When the electric telescopic rod 4 works, it can control the fixed block 5 and the motor 6 fixed at the bottom to approach or move away from the top of the workbench 1. The first support plate 8 is fixed to the bottom of the slot of the workbench 1 for receiving and placing gears. The second support plate 12 is fixed to the bottom of the workbench 1 through fixing columns. The second support plate 12 is square and its edges are rounded. A reduction motor 11 is fixed to the top of the second support plate 12. A turntable 10 is installed at the top end of the output shaft of the reduction motor 11. When the reduction motor 11 runs, it can drive the turntable 10 to rotate through the output shaft. A spiral slot is provided inside the turntable 10. A chute 13 is provided inside the workbench 1. The chutes 13 are in pairs, and there are several groups of chutes 13 arranged in a circle. The clamping components are slidably installed in the slot in the center of the workbench 1. There are several clamping components arranged in a circle. Multiple groups of clamping components can cooperate to clamp and fix the gears. The clamping component includes a second long slider 19 slidably installed inside the workbench 1 through the chute 13. A slider 20 is fixed to the side of the second long slider 19. The second long slider 19 can slide inside the chute 13 through the slider 20. One end of the second long slider 19 is fixed with a plate slot 18. A slot is provided inside the plate slot 18. An arc plate 14 is slidably installed through the slot and the plate slot 18. A rubber pad 16 is fixed to the side of the arc plate 14. When clamping and fixing the gear, the rubber pad 16 contacts the teeth. Since the rubber pad 16 is an elastic material, it can deform during clamping to protect the teeth. A clamping cone 17 is fixed to the side of the arc plate 14. The clamping cone 17 can be stuck into the gap between the teeth to play a lateral supporting role for the teeth, assisting in fixing the gear and also preventing the gear from rotating during the drilling process. A rotating clamping block 15 is fixed to the top of the arc plate 14. The handle design of the rotating clamping block 15 can facilitate lifting by hand. By lifting the rotating clamping block 15, the arc plate 14 can be taken out from the top of the plate slot 18 for replacement. When facing gears with different tooth ratios or gears with special-shaped teeth, as long as the corresponding arc plate 14 and clamping cone 17 are replaced, the compatibility of the device when facing gears with different tooth ratios or gears with special-shaped teeth can be improved. After the arc plate 14 is installed, the rotating clamping block 15 can be rotated 90 degrees. A buckle that is mutually clamped with the rotating clamping block 15 is provided on the top panel of the plate slot 18. When the rubber pad 16 completely enters the slot of the plate slot 18, the rotating clamping block 15 is rotated to the buckle and combined with the buckle to prevent the arc plate 14 from being displaced due to the vibration generated during the gear hole opening process, improving the stability of the arc plate 14 during the hole opening process.

[0028] A first long slider 9 is slidably mounted on the surface of the turntable 10. The top end of the first long slider 9 is fixed to the bottom of the second long slider 19. When the turntable 10 rotates, the first long slider 9 can slide along the spiral chute on the surface of the turntable 10. When the reduction motor 11 drives the turntable 10 to rotate, the first long slider 9 slides along the spiral groove on the surface of the turntable 10, driving the second long slider 19 fixed to the top of the first long slider 9 to move back and forth. When the turntable 10 rotates, all the first long sliders 9 mounted on the surface of the turntable 10 slide along the spiral groove on the surface of the turntable 10 uniformly. The second long sliders 19 installed inside the workbench 1 can move the same distance, improving the stability during clamping and the uniformity of the clamping force.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
