The top of the retraction box extends downward to form a cavity-like structure, and a grinding block that can be telescopically displaced is movably connected to the top opening of the retraction box.

[0009] Preferably, a spring 1 is fixedly connected between the two sides of the bottom of the grinding block and the inside of the retraction box, and the spring 1 can be used to enable the grinding block to contact the surface of the material tube after the retraction box moves upward.

[0010] The automobile parts punching device of the present invention has the following advantages:

[0011] 1. This is a punching device for automobile parts. During the punching operation of the material tube, the material tube is placed above the feed box. After the double-headed motor is started, it drives the threaded rods at both ends to rotate. The threaded rods cooperate with the threaded holes in the clamping tubes to move the two clamping tubes toward each other, thereby fixing the material tube on the positioning slot to ensure accurate positioning during the punching process. The punching mechanism is then used to pass through the positioning cylinder to complete the punching action. Next, the motor drives the rotating shaft to rotate counterclockwise to transfer the punched material tube to the unloading box. Then, the material tube can be unloaded from the unloading box smoothly, and the new material tube is sent from the feed box to the positioning slot to prepare for the next punching cycle.

[0012] 2. This automobile parts punching device, after completing the punching of the material tube, feeds the material counterclockwise through the rotating disk. At this time, the motor 2 is started, and the gear 1 at its output end drives the gear 3 and the gear 2 to rotate. As the gear 2 rotates, the material tube clamped in the middle also rotates. At the same time, the rotation of the rotating shaft 2 causes the two moving rings to move toward the center through the reciprocating thread groove. When the moving ring moves toward the center, the push rod pushes the grinding block to contact the surface of the material tube, and grinds it while the material tube rotates, thereby removing burrs and warping at the punching location.

[0013] 3. This is a punching device for automobile parts. When the rotating disk rotates to unload materials, the crown gear on the rotating shaft 1 drives the gear 4, which then drives the belt and the pulley 2 to rotate through the rotating shaft 3 and the pulley 1. The rotation of the pulley 2 rotates the connected reciprocating screw, and the moving plate and the positioning cylinder thereon are displaced through the insert block. At the same time, the rotating shaft 4 above the reciprocating screw is accelerated by the gear 6, and the eccentric block on its outer periphery vibrates, causing the waste generated by the punching in the positioning cylinder to fall off.

[0014] 4. This is a punching device for automobile parts. When the rotating shaft 4 rotates through the gear 6, the rectangular rod drives the half gear to rotate. The rotation of the half gear pushes the rack to move, causing the rack to drive the two positioning cylinders away from each other. The vibration generated by the eccentric block causes the waste in the positioning cylinder to fall. When the half gear is no longer engaged with the rack, the spring 2 rebounds quickly, causing the two positioning cylinders to close, and the waste is further removed through the impact when closing. As the rotating disk completes one rotation, the positioning cylinder returns to the initial position and is ready for the next punching. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The disclosure below provides many different embodiments or examples to implement different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present invention.

[0034] like Figure 1-Figure 5 As shown, a punching device for automobile parts of the present invention includes a punching mechanism 12 for punching holes in the parts, and the rotation of the punching mechanism 12 is driven by the punching device 11 arranged above, and the punching device 11 is supported and fixed by its base 1 below. A lifting base 13 is arranged between the area above the base 1 and the area below the punching mechanism 12, and the lifting base 13 can be lifted and displaced along the height of the punching device 11. When the automobile parts need to be punched, the punching mechanism 12 can be used to punch the automobile parts.

[0035] On one side of the upper side of the lifting base 13, a support frame 2 is fixedly connected to its surface, and a top plate 21 is fastened to the top of the support frame 2, and a rotating shaft 3 that can rotate is arranged below the top plate 21. The rotating shaft 3 and the top plate 21 are arranged opposite to each other, and the two ends of the rotating shaft 3 are supported and rotated by a rotating frame 24 fixedly connected to the surface of the support frame 2. The outer circumference of the rotating shaft 3 is also connected to a rotating disk 31 by welding on both sides, and the outer circumference of the rotating disk 31 is provided with a positioning groove 32 downward, and the positioning groove 32 is arranged in a triangular structure. A mounting frame 241 is also integrated on the rotating frame 24, and the motor 242 can be fixedly installed through the mounting frame 241, and the power output end of the motor 242 is connected to the rotating shaft 3, so that after the motor 242 is running, the rotating shaft 3 can be rotated together. At the same time, a mechanical brake is integrated in the motor 242, and the mechanical brake is used to prevent the motor shaft from rotating when the motor 242 is not working. The mechanical brake is preferably an electromagnetic type, and when the power of the motor 242 is turned off, the mechanical brake can lock the motor shaft.

[0036] At the same time, a support frame 131 is fixed on the other side above the lifting base 13 and opposite to the support frame 22. The height of the support frame 131 is higher than that of the support frame 22. A feed box 132 is arranged between the two support frames 22 and near the top. The two sides of the surface of the feed box 132 are fixedly connected to the surface of the support frame 131. At the same time, the feed box 132 is arranged in an inclined structure. A material pipe 134 is also filled above the feed box 132, and the end of the feed box 132 is close to one side of the positioning groove 32, through which the feed box 132 can make the material pipe 134 roll down. A material box 133 for punching and unloading is also arranged relatively below the feed box 132. The two sides of the surface of the material box 133 are fixedly connected to the surface of the support frame 131. At the same time, a positioning cylinder 233 for punching and positioning is also movably arranged on one side above the top plate 21. The positioning cylinder 233 is relatively located above the positioning groove 32.

[0037] like Figure 5-Figure 8As shown, rotating tubes 41 are provided on both sides of the positioning groove 32 to clamp and fix the material tube 134. The rotating tubes 41 are arranged opposite to each other, so that when the rotating tubes 41 move toward each other, they can clamp the material tube 134. The relative displacement of the rotating tubes 41 is driven by a double-headed motor 34 fixedly connected to the upper part of the rotating shaft 13, and the double-headed motor 34 can rotate together with the rotating shaft 13. Therefore, when the material tube 134 needs to be punched, the material tube 134 to be punched can be placed above the feed box 132, and then the punching mechanism 12 can pass through the positioning cylinder 233 downward to punch the material tube 134. After the punching is completed and moved upward, the motor 242 is operated, and then the rotating shaft 3 starts to rotate counterclockwise. At this time, the punched material tube 134 can be rotated to the discharge box 133, and then the material can be discharged from the discharge box 133. After moving from the discharge box 133 to the feed box 132, the material tube 134 above the feed box 132 can fall into the positioning slot 32, and then the material can be discharged and punched automatically.

[0038] The power output end of the double-headed motor 34 is integrally connected with a threaded rod 341, and the threads at both ends of the threaded rod 341 are arranged in a positive and negative shape. A moving groove 1 311 is provided through one side of the surface of the rotating disk 31, wherein the moving groove 1 311 and the threaded rod 341 are arranged coaxially and oppositely, and a clamping tube 4 extends from the moving groove 1 311 to the axis of the material tube 134, and limiting blocks 43 are relatively fixed on both sides of the surface of the clamping tube 4, and the clamping tube 4 can be displaced laterally through the limiting blocks 43. In addition, the end of the clamping tube 4 is coaxially movably connected with the rotating tube 41, so that the rotating tube 41 can rotate, and the threaded hole 45 provided at the other end of the clamping tube 4 is threadedly connected with the threaded rod 341. Therefore, after the material tube 134 passes through the feed box 132 and rolls to the top of the positioning groove 32, the double-headed motor 34 is running, and the threaded rods 341 arranged at both ends of the double-headed motor 34 can rotate together. Since the threaded rods 341 are threadedly connected with the threaded holes 45 arranged inside the clamping tube 4, the two opposite clamping tubes 4 can be displaced toward each other at the same time, and the material tube 134 above the positioning groove 32 is clamped and centered. This prevents deviation during punching, and prevents the punched material tube 134 from falling when unloading.

[0039] like Figure 5-Figure 9As shown, a gear 2 42 is fixedly connected to one side of the surface of the rotating tube 41, and a gear 3 51 is provided at one end of the rotating shaft 2 5 arranged below the gear 2 42. At the same time, both ends of the rotating shaft 2 5 penetrate the surface of the rotating disk 31 respectively, so that the rotating shaft 2 5 can rotate, and the gear 3 51 is meshed and connected with the gear 2 42. A connecting frame 44 is fixedly connected to one side of the outer peripheral surface of the clamping tube 4, and a motor 2 441 for driving the gear 3 51 to rotate is fixedly connected through the connecting frame 44. Therefore, when the motor 2 441 is running, the gear 1 442 provided at the output end of the motor 2 441 can drive the gear 3 51 meshed on one side. As the gear 3 51 rotates, the gear 2 42 meshed on the upper side can rotate together. Since the two gears 2 42 clamp the material tube 134, the material tube 134 can rotate together.

[0040] Reciprocating thread grooves 52 are respectively recessed inwardly on both sides of the outer circumference of the rotating shaft 2 5, and a moving ring 6 is sleeved on the outer circumference of the reciprocating thread groove 52. The moving ring 6 is sleeved on the outer circumference of the reciprocating thread groove 52 through a reciprocating hole 1 62 that penetrates through one side of the surface. A limiting column 312 extends toward the moving ring 6 on one side of the surface of the rotating disk 31, and a limiting hole 61 opened below one side of the surface of the moving ring 6 is penetrated by the limiting column 312. In addition, an insert is provided on the inner ring wall of the reciprocating hole 1 62, and one end of the insert extends into the path of the reciprocating thread groove 52, so that the moving ring 6 can reciprocate after the reciprocating thread groove 52 rotates.

[0041] A rotatable push rod 63 is hinged above the movable ring 6, and a retraction box 64 is hinged between the two push rods 63, and the top of the retraction box 64 extends downward to form a cavity-like structure, and a grinding block 65 that can be telescopically displaced is movably connected to the top opening of the retraction box 64, and a spring 641 is fixedly connected between the bottom sides of the grinding block 65 and the inside of the retraction box 64, so that after the retraction box 64 moves up, the grinding block 65 can contact the surface of the material tube 134 through the spring 641, and after the grinding block 65 contacts the surface of the material tube 134, the elastic force of the spring 641 will prevent the grinding block 65 from having a hard contact with the surface of the material tube 134, thereby affecting the displacement of the movable ring 6. Therefore, after the material tube 134 is punched, when the material tube 134 is fed counterclockwise through the rotating disk 31, the motor 2 441 is running. As the motor 2 441 is running, the gear 1 442 set at its output end can drive the gear 3 51 and the gear 2 42 to rotate. During the rotation of the gear 2 42, the material tube 134 clamped in the middle can rotate together. At the same time, after the rotating shaft 2 5 is rotated, the two moving rings 6 can be displaced toward each other at the same time through the reciprocating thread groove 52. As the moving rings 6 move toward the middle, the grinding block 65 can be in contact with the surface of the material tube 134 through the push rod 63. Then, the punched part of the material tube 134 can be polished under the rotation of the material tube 134 to prevent the punched holes from warping and burrs.

[0042] like Figure 4 and Figure 10-12 As shown, crown gears 33 are fixed at both ends of the rotating shaft 1 3, and a rotatable rotating shaft 3 243 is also provided on both sides of the supporting frame 2, and a gear 4 244 fixed at one end of the rotating shaft 3 243 is meshed and connected with the crown gear 33, and a pulley 1 245 is also fixed at the other end of the rotating shaft 3 243.

[0043] A reciprocating groove 23 is provided downwardly through the top of the top plate 21, and rotating holes 238 are provided on both sides of the top plate 21, through which a rotatable reciprocating screw 9 is arranged, and the end of the reciprocating screw 9 near one end of the pulley 1 245 is fixedly connected to the pulley 2 91, and the power is transmitted between the pulley 2 91 and the pulley 1 245 through the belt 93. Therefore, when the rotating shaft 3 243 rotates, the pulley 1 245 set at one end of the rotating shaft 3 243 can rotate the reciprocating screw 9 through the belt 93.

[0044] A reciprocating movable plate 231 is connected in a sliding manner inside the reciprocating groove 23, and a reciprocating hole 239 is penetrated by the reciprocating screw 9 through the surface of the reciprocating plate 231, and one end of the insert provided on the inner wall of the reciprocating hole 239 extends into the thread groove path of the outer peripheral surface of the reciprocating screw 9, that is, after the reciprocating screw 9 rotates, the movable plate 231 can reciprocate. At the same time, the positioning cylinder 233 is arranged above the movable plate 231, so that when the movable plate 231 is displaced, the positioning cylinder 233 can move together.

[0045] A gear 5 72 is meshed above the gear 6 92, and a rotating shaft 29 7 extends from one side of the surface of the gear 5 72 toward the positioning cylinder 233, and an eccentric block 73 is fixedly connected to the outer circumference of the rotating shaft 29 7. The rotating shaft 29 7 is supported and rotated by the rotating frame 22 fixedly arranged on both sides above the top plate 21. Therefore, when the rotating disk 31 rotates to unload materials, the crown gears 33 arranged at both ends of the rotating shaft 1 3 can drive the gear 4 244 meshingly connected on one side. After the gear 4 244 rotates, when the rotating shaft 3 243 and the pulley 1 245 rotate together, the pulley 2 91 can be driven to rotate through the belt 93. As the pulley 2 91 rotates, the reciprocating screw 9 connected to one side of the surface rotates. After the reciprocating screw 9 rotates, the movable plate 231 can be displaced to one side through the insert block. After the movable plate 231 moves, the positioning cylinder 233 arranged thereon can move together. When the reciprocating screw 9 rotates, the rotating shaft 4 7 above the reciprocating screw 9 accelerated by the gear 6 92 can rotate, and the eccentric block 73 arranged on the outer peripheral surface of the rotating shaft 4 7 can generate vibration during rotation, and the punched waste inside the positioning cylinder 233 can be dropped by its vibration.

[0046] like Figure 10-12 As shown, when the positioning cylinder 233 performs positioning punching, the punching mechanism 12 passes through the positioning cylinder 233 to punch holes, and the punching waste will remain inside the positioning cylinder 233, so in the subsequent punching operation, the waste will have a certain impact. A second moving groove 232 is opened downward above the moving plate 231, and the second moving groove 232 is opened below the positioning cylinder 233. At the same time, a slider 25 is connected to the inside of the second moving groove 232 in a sliding manner, and the bottom of the positioning cylinder 233 is connected to the top of the slider 25, and the positioning cylinder 233 is arranged in two semicircular structures.

[0047] Push-back plates 235 are fixedly connected to both sides above the moving plate 231, and a rack 234 is extended toward the push-back plate 235 on one side of the outer surface of the positioning cylinder 233, and a spring 236 is fixed between the end of the rack 234 and the push-back plate 235, and the two semicircular positioning cylinders 233 can be closed by the spring 236. A rotating frame 3 237 is fixed to one side above the push-back plate 235, and a rotatable half gear 8 is arranged between the two rotating frames 3 237, and the two ends of the half gear 8 are hinged with the rotating frame 3 237, and a rectangular rod 71 is extended toward the axis of the half gear 8 at the end of the rotating shaft 4 7, and a rectangular hole 81 is penetrated through one side of the surface of the half gear 8 for the rectangular rod 71 to pass through. When the rotating shaft 297 rotates through the gear 6 92, the rectangular rod 71 can drive the half gear 8 to rotate, and after the half gear 8 rotates, the rack 234 can move toward the push-back plate 235, and the two positioning cylinders 233 move away from each other, and the vibration generated by the eccentric block 73 can make the waste inside the positioning cylinder 233 fall. And after the half gear 8 is no longer engaged with the rack 234, the two positioning cylinders 233 that are away from each other can be closed by the rapid rebound of the spring 236, and the impact generated during the closing can further make the waste on the positioning cylinder 233 fall. After the rotating disk 31 rotates one circle, the positioning cylinder 233 can return to its original position to punch holes again.

[0048] Working principle of a punching device for automobile parts:

[0049] When the material tube 134 needs to be punched, the material tube 134 to be punched can be placed above the feed box 132, and then the double-headed motor 34 is operated. After the double-headed motor 34 is operated, the threaded rods 341 arranged at both ends can rotate together. Since the threaded rods 341 and the threaded holes 45 provided inside the clamping tube 4 form a threaded connection, the two relative clamping tubes 4 can be displaced toward each other at the same time, and then the material tube 134 above the positioning groove 32 is clamped and centered to prevent displacement during punching. At the same time, the material tube 134 after punching can be prevented from falling when unloading. Then, the punching mechanism 12 passes downward through the positioning cylinder 233 to punch the material tube 134. After the punching is completed and moved upward, the motor 242 is operated, and then the rotating shaft 3 starts to rotate counterclockwise. At this time, the punched material tube 134 can be rotated to the unloading box 133, and then the material can be unloaded from the unloading box 133. After moving from the unloading box 133 to the feeding box 132, the material tube 134 above the feeding box 132 can fall into the positioning groove 32, and then the unloading and punching can be automatically performed;

[0050] After the material tube 134 is punched, when the material tube 134 is fed counterclockwise through the rotating disk 31, the motor 2 441 is running. As the motor 2 441 is running, the gear 1 442 set at its output end can drive the gear 3 51 and the gear 2 42 to rotate. During the rotation of the gear 2 42, the material tube 134 clamped in the middle can rotate together. At the same time, after the rotating shaft 2 5 rotates, the two moving rings 6 can be displaced toward each other at the same time through the reciprocating thread groove 52. As the moving rings 6 move toward the middle, the grinding block 65 can be made to contact the surface of the material tube 134 through the ejector rod 63. Then, the punched part of the material tube 134 can be polished under the rotation of the material tube 134 to prevent the punched hole from warping and burrs.

[0051] At the same time, when the rotating disk 31 rotates to unload materials, the crown gears 33 arranged at both ends of the rotating shaft 1 3 can drive the gear 4 244 meshingly connected on one side. After the gear 4 244 rotates, when the rotating shaft 3 243 and the pulley 1 245 rotate together, the pulley 2 91 can be driven to rotate through the belt 93. As the pulley 2 91 rotates, the reciprocating screw 9 connected to one side of the surface rotates. After the reciprocating screw 9 rotates, the movable plate 231 can be displaced to one side through the insert block. After the movable plate 231 moves, the positioning cylinder 233 arranged thereon can move together. When the reciprocating screw 9 rotates, the rotating shaft 4 7 above the reciprocating screw 9 accelerated by the gear 6 92 can rotate, and the eccentric block 73 arranged on the outer circumference of the rotating shaft 4 7 can generate vibration during rotation, and the waste punched inside the positioning cylinder 233 can fall out through its vibration.

[0052] Finally, when the rotating shaft 24 7 is rotated by the gear 6 92, the rectangular rod 71 can be used to drive the half gear 8 to rotate, and after the half gear 8 rotates, the rack 234 can be moved toward the push-back plate 235, and the two positioning cylinders 233 are separated from each other, and the vibration generated by the eccentric block 73 can be used to make the waste inside the positioning cylinder 233 fall. After the half gear 8 is no longer engaged with the rack 234, the two positioning cylinders 233 that are separated from each other can be closed by the rapid rebound of the spring 236, and the impact generated during the closing can further make the waste on the positioning cylinder 233 fall. After the rotating disk 31 rotates one circle, the positioning cylinder 233 can return to its original position to punch holes again.

[0053] It should be noted that the specific models and specifications of the punching device 11, motor 1 242, motor 2 441 and double-headed motor 34 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0054] The power supply and principles of the punching device 11, motor 1 242, motor 2 441 and double-head motor 34 are clear to those skilled in the art and will not be described in detail here.
