[0022] Beneficial effects

[0023] According to various embodiments of the present invention, the gear stamping processing apparatus, compared with the conventional gear stamping, can limit the gear chuck to the bottom of the stamping head by a limiting block after the gear chuck moves to the bottom of the stamping head, so as to make the shaft hole stamping more precise. After stamping, the bottom end of the gear shaft hole can be polished. Moreover, when the gear chuck moves to the receiving groove, it can be flipped to unload the gear.

[0024] Furthermore, by setting up a positioning mechanism and a gear chuck limiting mechanism, the gear to be processed is placed into the gear chuck for positioning. When the drive motor drives the turntable to rotate clockwise, the square shaft on the connecting shaft touches the second micro-touch switch, causing the limiting lifting cylinder to drive two sets of limiting blocks to rise from the limiting block insertion holes. When the gear chuck touches the third micro-touch switch on the limiting block, the drive motor stops moving. At the same time, the stamping cylinder drives the stamping head to move downward to punch the shaft hole in the middle of the gear. Simultaneously, the keyway stamping structure on the stamping head can be used to stamp out the keyway structure synchronously. During the downward stamping process, the lower pressure ring first contacts the gear and presses down on the gear to prevent the gear from shifting during stamping. When the stamping cylinder drives the stamping head to move upward, the other end of the control frame touches the first micro-touch switch, causing the grinding part to activate and grind the bottom of the gear shaft hole. After grinding for 5 seconds, the grinding lifting cylinder drives the motor mounting frame and the grinding motor to return to their original positions. At the same time, the limiting lifting cylinder drives the two sets of limiting blocks to return to their original positions, and the drive motor continues to drive the turntable to rotate.

[0025] Furthermore, by setting a flip gear on the connecting shaft, when the connecting shaft moves with the turntable to the notch on the inner limit ring, the square shaft on the connecting shaft disengages from the inner limit ring, and the flip gear meshes with the sector teeth, thereby causing the connecting shaft to flip at the notch, causing the gear chuck to flip at the sector notch, so that the gear in the gear chuck falls into the receiving groove, and when the flip gear just disengages from the sector teeth, the gear chuck just returns to its front side and sticks to the upper pad, and the square shaft on the connecting shaft sticks to the inner limit ring again.

[0026] In addition, by setting an unloading ramp inside the receiving slot, the gear that falls into the receiving slot can slide out along the outlet hole. Moreover, by connecting an inclined arc-shaped guide plate to the top of the stamping head, when the shaft hole slices punched into the stamping head reach the oblique cut end in sequence, the shaft hole slices can be pushed out from the oblique cut by the arc structure at the bottom of the arc-shaped guide plate and fall onto the gear of the gear chuck, and fall into the receiving slot together with the gear.

Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0044] Example: Please refer to Figures 1 to 11:

[0045] The present invention proposes a stamping processing device for metal gears, comprising: a support cylinder 1, a support ring plate 2, a travel mechanism 3, a gear chuck limiting mechanism 4, and a stamping mechanism 5;

[0046] The upper end of the support cylinder 1 is provided with a fan-shaped notch A, and the bottom of the fan-shaped notch A is provided with a receiving groove 101. The top outer side of the support cylinder 1 is provided with an upper pad plate 103, and the upper pad plate 103 is provided with a fan-shaped notch B. The two ends of the fan-shaped notch B are arc-shaped chamfered structures, and are vertically opposite to the fan-shaped notch A. The inner support plate 102 is also connected in the middle of the inside of the support cylinder 1. The rear support 105 is fixedly connected in the middle of the rear end of the support cylinder 1.

[0047] Furthermore, according to an embodiment of the present invention, as shown in Figures 1 and 10, the support ring plate 2 is installed at the top center of the support cylinder 1 and is located at the inner center of the upper pad plate 103. The top side of the support ring 2 is provided with an outer pad ring 201 and an inner limiting ring 202 in sequence. The inner limiting ring 202 is provided with a notch, and the two ends of the notch are respectively arc-shaped chamfered structures, which are aligned with the two fan-shaped edges of the fan-shaped notch A. The top of the support cylinder 1 is also fixedly installed with a fan-shaped tooth 106, which is located on the inner side of the support ring plate 2 and is also aligned with the two fan-shaped edges of the fan-shaped notch A at both ends. The inner limiting ring 202 is also inlaid with a second micro-touch switch 203, which is electrically connected to the external control box.

[0048] Furthermore, according to an embodiment of the present invention, as shown in Figures 2 and 7, the positioning mechanism 3 includes a drive motor 301, a mounting frame 302, a turntable 303, an arc-shaped support plate 304, a rotating head 305, a reversing gear 306, a connecting shaft 307, and a gear chuck 308. The drive motor 301 is fixed inside the mounting frame 302 and electrically connected to an external control box. The mounting frame 302 is connected to the bottom center of the support cylinder 1. The motor axial direction of the drive motor 301 passes through the support cylinder 1 and is fixedly connected to the turntable 303. The bottom side of the turntable 303 is attached to the arc-shaped support plate 304. Two sets of arc-shaped support plates 304 are provided and are connected to the top center of the support cylinder 1 in a relatively opposite structure. The two opposite ends of the turntable 303 are respectively fixedly connected to a rotating head. The rotating head 305 and the connecting shaft 307 are composed of two sets of round shafts and two sets of square shafts connected at intervals. One set of round shafts and one set of square shafts are respectively located at the inner and outer ends of the connecting shaft 307. The bottom side of the square shaft between the two sets of round shafts is attached to the inner limiting ring 202, and the bottom side of the round shafts of the two sets of square shafts is attached to the outer washer ring 201. A reversing gear 306 is fixedly connected to the inner round shaft of the connecting shaft 307 and rotatably clamped into the rotating head 305. The outer end of the square shaft on the outer side of the connecting shaft 307 is fixedly connected to the gear chuck 308. The inner side of the gear chuck 308 has a circular groove for installing gears, and the inner wall of the circular groove has two sets of opposing limiting teeth 3081. A bottom through hole 3082 is provided in the middle of the bottom of the circular groove. Circular holes A1031 and B10... The inner diameters of the four couplings are larger than the inner diameter of the bottom through hole 3082 and smaller than the outer diameter of the gear chuck 308. During clockwise rotation of the coupling 307, its upper shaft first touches the second micro-touch switch 203, after which the gear chuck 308 moves to directly below the stamping head 504. The flipping gear 306 meshes with the sector teeth 106 as it rotates with the turntable 303. The flipping gear 306 completes one full rotation from engagement to disengagement with the sector teeth 106, allowing the gear to be processed to be placed into the gear chuck 308 for positioning. When the drive motor 301 drives the turntable 303, the two sets of couplings 307, and the two sets of gear chucks 308 to rotate clockwise, the gear chuck 308 rests against the upper pad 103, and the square shaft on the coupling 307 rests against... On the inner limit ring 202, the connecting shaft is prevented from flipping. The drive motor 301 continues to drive the turntable 303 to rotate. When the connecting shaft 307 moves with the turntable 303 to the notch on the inner limit ring 202, the square shaft on the connecting shaft 307 disengages from the inner limit ring 202. The flipping gear 306 just meshes with the sector tooth 106, causing the connecting shaft 307 to flip at the notch. This causes the gear chuck 308 to flip at the sector notch, causing the gear in the gear chuck 308 to fall into the receiving groove 101. When the flipping gear 306 just disengages from the sector tooth 106, the gear chuck 308 just returns to its original position and sticks to the upper pad 103. The square shaft on the connecting shaft 307 then sticks to the inner limit ring 202 again.

[0049] Furthermore, according to an embodiment of the present invention, as shown in Figures 7 and 11, the gear chuck limiting mechanism 4 includes a limiting block 401, a U-shaped connecting rod 402, a limiting lifting cylinder 403, and a rubber buffer pad 4031. Two sets of limiting blocks 401 are provided, each placed within a limiting block insertion hole 1032 in the upper pad 103. The support cylinder 1 also has a slot opposite to the limiting block insertion hole 1032. Both ends of the U-shaped connecting rod 402 pass upwards through the slot and are fixedly connected to the limiting block 401. The bottom middle of the U-shaped connecting rod 402 is fixedly connected to the telescopic end of the limiting lifting cylinder 403. The limiting lifting cylinder 403 is mounted on the inner support plate 102 and electrically connected to the external control box. The top of the telescopic end of the limiting lifting cylinder 403... It is also connected to a rubber buffer pad 4031. One side of the limit block 401 has an arc-shaped structure, and a third micro-touch switch 4011 is embedded in the middle of the inner arc structure of a set of limit blocks 401 near the stamping cylinder 501. The third micro-touch switch 4011 is electrically connected to the external control box. When the square shaft on the connecting shaft touches the second micro-touch switch 203, the control box controls the limit lifting cylinder 403 to drive the two sets of limit blocks 401 to rise from the limit block insertion hole 1032, limiting the gear chuck 308. When the gear chuck 308 touches the third micro-touch switch 4011 on the limit block 401, the control box controls the drive motor 301 to stop rotating. Moreover, the limit lifting cylinder 403 can also drive the two sets of limit blocks 401 to return to their original positions.

[0050] Furthermore, according to an embodiment of the present invention, as shown in Figures 3 and 5, the stamping mechanism 5 includes a stamping cylinder 501, a U-shaped frame 502, an upper connecting plate 503, a stamping head 504, a lower pressing ring 505, a guide rod 506, a spring 507, and a control frame 508; the stamping cylinder 501 is fixedly installed on the top of the rear support 105 and electrically connected to an external control box, and the telescopic end of the stamping cylinder 501 passes downward through the top of the rear support 105 and is connected to the U-shaped frame 502; the stamping head 504 has a hollow internal structure and is provided with a keyway. The stamping structure has a beveled end at one top, which slopes downwards to one side. The other end of the stamping head 504 is connected to an arc-shaped guide plate 5041, the top of which slopes to one side and is fixedly connected to the inner top of the U-shaped frame 502. An upper connecting plate 503 is also fixedly connected to the beveled end of the stamping head 504. A lower pressure ring 505 is located directly below the upper connecting plate 503, and two sets of guide rods 506 are connected to it. The top of each guide rod 506 is threaded and slides upwards through the upper connecting plate 503. A nut is screwed on at the rear, and springs 507 are respectively fitted on the guide rod 506. One end of the control frame 508 is fixedly connected to the U-shaped frame 502 and the upper connecting plate 503, and the other end is attached to the vertical plate inside the rear bracket 105. When the gear chuck 308 touches the third micro-touch switch 4011 on the limit block 401, the control box also controls the stamping cylinder 501 to move, driving the stamping head to move downward to punch the shaft hole in the middle of the gear. At the same time, the keyway stamping structure on the stamping head can be used to stamp out the keyway structure simultaneously, and the punching is completed. Afterwards, the stamping cylinder 501 drives the stamping head 504 to move upwards, and the other end of the control frame 508 touches the first micro-touch switch 1051 again. At this time, the control box controls the grinding lifting cylinder 602 and the grinding motor 604 to operate. After multiple stampings, when the shaft hole slices that have been punched into the stamping head 504 reach the oblique cut end in sequence, they can be pushed out from the oblique cut by the arc structure at the bottom of the arc guide plate 5041 and fall onto the gear of the gear chuck 308. They then fall into the receiving slot 101 together with the gear.

[0051] Furthermore, according to an embodiment of the present invention, as shown in FIG6, the receiving groove 101 has a fan-shaped structure, with an outlet hole 1012 at its outer arc end, and an unloading inclined plate 1011 installed inside. The unloading inclined plate 1011 is inclined downward toward the outlet hole 1012, so that the gear and shaft hole plate that fall into the receiving groove 101 can flow out along the outlet hole 1012.

[0052] Furthermore, according to an embodiment of the present invention, as shown in FIG3, a first micro-touch switch 1051 is also embedded in the vertical plate inside the rear bracket 105. The first micro-touch switch 1051 is electrically connected to the external control box. After the bottom end of the stamping head 504 moves upward and away from the top end of the gear chuck 308 by 5cm, the other end of the control frame 508 touches the first micro-touch switch 1051. During the stamping process, the stamping head 504 moves downward under the drive of the stamping cylinder 501 to stamp the gear shaft hole. At this time, the other end of the control frame 508 touches the first micro-touch switch 1051, and the control box will not control other... When the component moves, as the stamping cylinder 501 drives the stamping head 504 to move upward, the other end of the control frame 508 touches the first micro-touch switch 1051 again. At this time, the control box controls the grinding lifting cylinder 602 and the grinding motor 604 to move. The grinding lifting cylinder 602 pushes the motor mounting bracket 603, the grinding motor 604 and the grinding disc 605 to move upward synchronously until the grinding disc 605 is attached to the bottom side of the gear and then stops. The grinding motor 604 drives the grinding disc 605 to rotate and grind the bottom side of the gear shaft hole. After 5 seconds, the grinding lifting cylinder 602 drives the motor mounting bracket 603 and the grinding motor 604 to return to their original positions.

[0053] Furthermore, according to an embodiment of the present invention, as shown in Figures 7 and 9, the upper pad 103 and the support cylinder 1 are respectively provided with a circular hole A1031 and a circular hole B104, and the circular holes A1031 and B104 are vertically opposite each other and located directly below the punch head 504. A grinding part 6 is also provided on the bottom side of the circular hole B104, and the grinding part 6 includes a bracket 601, a grinding lifting cylinder 602, a motor mounting bracket 603, a grinding motor 604, and a grinding disc 605. The bracket 601 is located directly below the circular hole B104, and its top end is fixedly connected to the support cylinder 1. The lower end of the grinding lifting cylinder 602 is clamped on the inner support plate 102, and its telescopic end passes through the bracket 601 and is fixedly connected to the motor mounting bracket 603. The grinding motor 604 is installed in the motor mounting bracket 603, and a support plate 6041 is fixedly installed on its motor shaft. The grinding lifting cylinder 602 and the grinding motor 604 are electrically connected to the external control box. The grinding disc 605 is fixed to the motor shaft and the support plate 6041 by internal hexagon screws, and the top of the grinding disc 605 is flush with the bottom surface of the round hole B104. When the stamping cylinder 501 moves upward, the other end of the control frame 508 touches the first micro-touch switch 1051 again. At this time, the control box controls the grinding lifting cylinder 602 and the grinding motor 604 to move. The grinding lifting cylinder 602 pushes the motor mounting frame 603, the grinding motor 604 and the grinding disc 605 to move upward synchronously until the grinding disc 605 is attached to the bottom side of the gear and then stops. The grinding motor 604 drives the grinding disc 605 to rotate and grind the bottom side of the gear shaft hole. After 5 seconds, the grinding lifting cylinder 602 drives the motor mounting frame 603 and the grinding motor 604 to return to their original positions.

[0054] The specific usage and function of this embodiment: In this invention, the gear to be processed is first placed into the gear chuck 308 for positioning. When the drive motor 301 drives the turntable 303, the two sets of connecting shafts 307, and the two sets of gear chucks 308 to rotate clockwise, the gear chuck 308 is attached to the upper pad 103, and the square shaft on the connecting shaft 307 is attached to the inner limit ring 202, preventing the connecting shaft from flipping. When the square shaft on the connecting shaft touches the second micro-touch switch 203, the control box controls the limit lifting cylinder 403 to drive the two sets of limit blocks 401 to rise from the limit block insertion hole 1032, limiting the gear chuck 308. When the gear chuck 308 touches the third micro-touch switch 4011 on the limit block 401, the control box controls the lifting cylinder 403 to lift the two sets of limit blocks 401 from the limit block insertion hole 1032, limiting the gear chuck 308. When the gear chuck 308 touches the third micro-touch switch 4011 on the limit block 401, the control box... The control box stops the drive motor 301 and simultaneously controls the stamping cylinder 501 to move downwards, punching the shaft hole in the middle of the gear. While the stamping cylinder 501 moves downwards, the other end of the control frame 508 touches the first micro-switch 1051. The control box does not control other components. Utilizing the keyway stamping structure on the stamping head 504, the keyway structure can be stamped synchronously. After punching, the stamping cylinder 501 drives the stamping head 504 upwards, and the other end of the control frame 508 touches the first micro-switch 1051 again. At this time, the control box controls the grinding lifting cylinder 602 and the grinding motor 604 to move. The grinding lifting cylinder 602 pushes the motor mounting bracket 603 and the grinding... The grinding motor 604 and grinding disc 605 move upward synchronously until the grinding disc 605 is against the bottom side of the gear and then stop. The grinding motor 604 drives the grinding disc 605 to rotate, grinding the bottom side of the gear shaft hole. After 5 seconds, the grinding lifting cylinder 602 drives the motor mounting bracket 603 and the grinding motor 604 to return to their original positions. At the same time, the limit lifting cylinder 403 drives the two sets of limit blocks 401 to return to their original positions. The drive motor 301 continues to drive the turntable 303 to rotate. When the connecting shaft 307 moves with the turntable 303 to the notch on the inner limit ring 202, the square shaft on the connecting shaft 307 disengages from the inner limit ring 202. The flipping gear 306 just meshes with the sector gear 106, causing the connecting shaft 307 to flip at the notch, and the gear chuck 308 to rotate at the sector notch. The gear is flipped so that the gear in the gear chuck 308 falls into the receiving groove 101. The gear that falls into the receiving groove 101 flows out through the outlet hole 1012 under the action of the inclined unloading plate 1011. When the flipped gear 306 just disengages from the sector tooth 106, the gear chuck 308 just returns to its original position and sticks to the upper pad 103. The square shaft on the connecting shaft 307 sticks to the inner limit ring 202 again. After multiple stampings, when the shaft hole slices punched into the stamping head 504 push to the oblique cut end in sequence, they can be pushed out from the oblique cut by the arc structure at the bottom of the arc guide plate 5041 and fall onto the gear in the gear chuck 308. They fall into the receiving groove 101 together with the gear.

[0055] Finally, it should be noted that when describing the position of each component and the mating relationship between them, the present invention usually uses one or a pair of components as examples. However, those skilled in the art should understand that such positions, mating relationships, etc., are also applicable to other components or other pairs of components.

[0056] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention, which is determined by the appended claims.
