Description

Technical Field

[0001] This application relates to the technical field of integrated punching and tapping processing, and particularly to an integrated punching and tapping processing equipment for automotive parts. Background Art

[0002] Punching is to use a punching press or a punching machine. By placing the workpiece in a mold and then applying an impact force to the plate through a punch, holes are formed in the workpiece under the action of the punch and the mold. Tapping is to perform internal thread processing on the hole of the workpiece using a tapping tool (such as a tap) based on the holes formed by punching or drilling.

[0003] When performing punching and tapping processing on a support seat workpiece at the bottom of an automotive seat frame as shown in Figure 5 , generally, a punching device is used to first punch the workpiece, and then a tapping device is used to thread the inner wall of the hole. Since the punching device and the tapping device are separated from each other and do not interfere with each other, the overall processing speed is relatively fast. Another method is to use an integrated punching and tapping device for processing. The integrated device has a high degree of integration, requires fewer operators, and occupies less floor space. The specific operation process is as follows: The conveyor belt transports the workpiece to be processed to the punching die. A feeding structure such as an electric push rod or a mechanical gripper transports the workpiece into the punching die for punching. After punching, the workpiece is moved to the tap for tapping. After the tapping operation is completed, the punching die is fed again to start the next processing cycle.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: Since the punching process is carried out by the rapid stamping of the punch, the punching process speed is relatively fast. However, tapping requires the tap to move to the workpiece and then rotate for tapping. The tapping process is slower than the punching process. After each punching is completed, it is necessary to wait for the tapping to end before proceeding to the next step, which leads to a relatively slow overall processing speed of the integrated punching and tapping device. Summary of the Invention

[0005] In order to improve the problem that a long waiting time is required after each cycle of the punching operation, this application provides an integrated punching and tapping processing equipment for automotive parts.

[0006] An integrated punching and tapping processing equipment for automotive parts provided by this application adopts the following technical solutions:

[0007] A punching-tapping integrated processing equipment for automobile parts, comprising a machine body, a conveyor belt, a punching arm and a tapping arm, the output end of the punching arm is fixedly connected to a punch, and the output end of the tapping arm is provided with a tap, characterized in that: a chassis ring connected to a power source is rotatably connected to the machine body, an inner material distribution plate is fixedly connected to the inner side of the chassis ring, and an outer material distribution plate is fixedly connected to the outer side of the chassis ring, two punching dies are fixedly connected to the chassis ring and are evenly distributed, and the top of the inner material distribution plate away from the punch and the top of the outer material distribution plate away from the punch are both fixedly connected to the tapping dies, there are two tapping arms, and they are respectively located above the two tapping dies, the punching dies and the tapping dies are both open at both ends along the radial direction of the chassis ring, and when the chassis ring is in a stationary state, the two tapping dies and the two punching dies are in a collinear line, and the chassis ring is provided with a waste opening below the punching dies;

[0008] The machine body is provided with a transfer component for transferring the workpiece in the punching die between the two tapping dies to one of the tapping dies, and a loading component for transferring the workpiece on the conveyor belt to the punching die under the punch. The machine body is also provided with a driving component for driving the transfer component and the loading component.

[0009] By adopting the above technical solution, the transmission belt conveys the workpiece to the punching die, the driving component drives the loading component to make the workpiece enter the punching die, and then the punching arm presses down to make the punch punch a hole in the workpiece, and the waste falls from the waste outlet, and then the punching arm moves up to make the punch separate from the workpiece, and then the chassis ring rotates to the opposite position of the punching die and the tapping die, the driving component drives the transfer component to move the workpiece to the tapping die on the external material distribution plate, and then the tapping arm drives the tap to perform tapping operation. During the tapping operation, the chassis ring rotates to drive another punching die to move to the loading component for loading and punching operations. After the punching is completed, the chassis ring Rotate to move the punching die to the position opposite to the tapping die, and then the transfer component moves the workpiece to the tapping die on the inner dividing plate. At this time, the first punching die moves to the loading component for loading and punching, and then moves to the tapping die on the outer dividing plate. The transfer component moves the workpiece in the punching die toward the tapping die on the outer dividing plate, and the moved workpiece pushes out the workpiece in the tapping die, completing the unloading while also updating the workpiece to be processed in the tapping die. Since the punching operation is shared by two tapping stations, the whole process greatly shortens the waiting time required after each punching operation is completed.

[0010] Optionally, the driving assembly includes a driving gear ring fixedly connected to the peripheral wall of the bottom end of the chassis ring, an energy storage gear rotatably connected to the body and meshed with the driving gear ring, a spring provided on the energy storage gear, a one-way gear rotatably connected to the body, and a transmission shaft coaxially provided at the end of the one-way gear. The one-way gear is meshed with the energy storage gear. When the driving gear ring drives the energy storage gear to rotate, the energy storage gear drives the one-way gear to rotate idly. When the spring drives the energy storage gear to rotate, the one-way gear drives the transmission shaft to rotate synchronously. A disengaging member for disengaging the driving gear ring from meshing with the energy storage gear is further provided on the driving gear ring; the disengaging member is a toothless portion formed on the driving gear ring, and there are two toothless portions. When the punching die moves to face the tapping die, the toothless portion on the driving gear ring faces the energy storage gear.

[0011] By adopting the above technical solution, when the chassis ring rotates, the driving gear ring drives the energy storage gear to rotate, so that the spring on the energy storage gear is tightened. During this process, the energy storage gear drives the one-way gear to rotate, but the one-way gear rotates idly and does not drive the transmission shaft to rotate. When the punching die on the chassis ring moves to the corresponding position, the chassis ring is briefly stationary. At this time, the toothless portion on the driving gear ring faces the energy storage gear, so that the driving gear ring is disengaged from meshing with the energy storage gear. At this time, the energy storage gear is released from the restraint of the driving gear ring and is driven by the spring, so that the transmission shaft rotates to drive the one-way gear to rotate. At this time, the one-way gear drives the transmission shaft to rotate again. The rotating transmission shaft provides a power source with stable rhythm for the transfer assembly and the driving assembly. In this process, there is no need to add other hardware devices such as electronic control and corresponding software algorithms, which greatly saves the production cost; after the chassis ring continues to rotate, the toothless portion is not facing the energy storage gear, and the driving gear ring meshes with the energy storage gear again. The structure of the energy storage gear for energy storage and energy release is simple and has high stability.

[0012] Optionally, a one-way block is elastically hinged to the end of the transmission shaft located inside the one-way gear. The one-way gear includes an outer tooth portion meshed with the energy storage gear and a ratchet tooth portion meshed with the one-way block. When the one-way block is in a free state, the one-way block is in a meshed state with the ratchet tooth portion.

[0013] By adopting the above technical solution, when the one-way gear is indirectly driven by the driving gear ring, the ratchet tooth portion presses the one-way block, and the one-way block reciprocates and shakes due to elastic action. At this time, the ratchet tooth portion cannot push the one-way block. When the one-way gear is indirectly driven to rotate by the spring, due to the change of the rotation direction, at this time, the ratchet tooth portion pushes the one-way block to rotate, so that the transmission shaft rotates.

[0014] Optionally, the transfer component includes a driven disk connected to the transmission shaft, a first connecting rod eccentrically hinged to the end face of the driven disk, a lead screw slidably connected to the machine body, a threaded gear rotatably connected to the machine body, a rack slidably connected to the machine body and meshed with the threaded gear, and a push rod fixed to the side of the rack close to the chassis ring. One end of the first connecting rod away from the driven disk is hinged to the end of the lead screw, the threaded gear is threadedly sleeved on the end of the lead screw away from the first connecting rod, and a chute slidably adapted to the push rod is formed in the punching die.

[0015] By adopting the above technical solution, when the transmission shaft rotates, the driven disk rotates accordingly. At this time, the first connecting rod drives the lead screw to move forward or backward, and the threaded gear rotates forward or backward accordingly, and then pushes the rack to move toward the side close to the outer material distribution plate or the side close to the inner material distribution plate, so that the push rod also moves synchronously. That is, the push rod pushes the workpiece in the punching die into the tapping die through the chute, and the workpiece to be tapped moves the tapped workpiece in its advancing direction out of the company die to complete the unloading and loading of the tapping die; by setting a suitable lead screw thread, the rotation stroke and torque of the threaded gear can be changed. That is, after punching, the workpiece is easily adhered to the punching die due to burrs or water vapor on the workpiece, and a suitable lead screw nut can amplify the torque, so that the workpiece in the punching die is smoothly pushed out.

[0016] Optionally, the feeding component includes a feeding rod slidably connected to the machine body, a second connecting rod hinged to the end of the feeding rod away from the punching die, and a feeding disk connected to the transmission shaft. One end of the second connecting rod away from the feeding rod is eccentrically hinged to the end face of the feeding disk.

[0017] By adopting the above technical solution, the rotation of the transmission shaft drives the feeding disk to rotate, so that the second connecting rod moves, and then the feeding rod makes a reciprocating motion. Since the workpiece needs to be quickly pushed into the feeding process and then retracted to prepare for the next feeding, the movement frequency is relatively high. The simple structure of the feeding component is more suitable for the rapid reciprocating motion of the push rod, and the daily maintenance such as lubrication and maintenance is also relatively simple.

[0018] Optionally, water permeable holes are formed in the side wall of the tapping die, and two rows of cooling spray pipes are arranged on the machine body. The cooling spray pipe in the lower row points to the bottom end of the workpiece through the water permeable holes, and the cooling spray pipe in the upper row is located above the tapping die and points to the top of the workpiece.

[0019] By adopting the above technical solution, during the tapping operation, the cooling spray pipe in the upper row sprays and cools the upper working part of the workpiece, and the cooling spray pipe in the lower row sprays and cools the lower working part of the workpiece through the water permeable holes, thereby reducing the occurrence of sintering, jamming, chipping and other situations.

[0020] Optionally, an elastic retaining piece is fixedly connected to one end of the tapping die away from the push rod. When the elastic retaining piece is in a natural state, the elastic retaining piece is in contact with the workpiece in the tapping die. An elastic retaining piece is also fixedly connected to one end of the punching die at the punch away from the feeding rod.

[0021] By adopting the above technical solution, when the push rod pushes the workpiece into the tapping die, the elastic retaining piece resists the workpiece to prevent the workpiece from sliding due to inertia to a position where tapping is to be performed on the workpiece without being aligned with the tap. That is, the elastic retaining piece on the tapping die effectively reduces the error during tapping. Similarly, the elastic retaining piece on the punching die also reduces the error during punching operation.

[0022] Optionally, a slideway is communicated with one end of the tapping die away from the punching die between the two tapping dies, and a collection box with a water filter opening is placed at the bottom of the slideway.

[0023] By adopting the above technical solution, after tapping is completed, the push rod pushes the workpiece out of the tapping die. The pushed workpiece enters the slideway and slides uniformly into the collection box. Moreover, the coolant on the die in the collection box is filtered by the water filter opening on the collection box to reduce the weight of the workpiece during subsequent transportation.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The conveyor belt conveys the workpiece to the punching die. The driving assembly drives the feeding assembly to make the workpiece enter the punching die. Then the punching arm presses down to punch a hole in the workpiece with the punch, and the waste material falls from the waste outlet. Then the punching arm moves up to separate the punch from the workpiece. Then the chassis ring rotates to a position where the punching die is opposite to the tapping die. The driving assembly drives the transfer assembly to move the workpiece to the tapping die on the outer material distribution plate. Then the tapping arm drives the tap to perform tapping operation. During the tapping operation, the chassis ring rotates to drive another punching die to move to the feeding assembly for feeding and punching operations. After punching is completed, the chassis ring rotates to move the punching die to a position opposite to the tapping die. Then the transfer assembly moves the workpiece to the tapping die on the inner material distribution plate. At this time, the first punching die moves to the feeding assembly for feeding and punching again, and then moves to the tapping die on the outer material distribution plate. The transfer assembly moves the workpiece in the punching die towards the direction of the tapping die on the outer material distribution plate. The moving workpiece ejects the workpiece in the tapping die, that is, while unloading, the workpiece to be processed in the tapping die is updated; since the punching operation is shared by two tapping stations, the waiting time required after each punching operation is greatly shortened during the whole process;

[0026] 2. When the chassis ring rotates, the driving gear ring drives the energy storage gear to rotate, tightening the spring on the energy storage gear. During this process, the energy storage gear drives the one-way gear to rotate, but the one-way gear idles and does not drive the transmission shaft to rotate. When the punching die on the chassis ring moves to the corresponding position, the chassis ring stops briefly. At this time, the disengaging part disengages the driving gear from the meshing connection with the energy storage gear, causing the energy storage gear to reverse driven by the spring to drive the one-way gear to rotate. At this time, the one-way gear drives the transmission shaft to rotate again. The rotating transmission shaft provides a power source with stable rhythm for the transfer component and the driving component. In this process, there is no need to add other hardware devices such as electronic control and corresponding software algorithms additionally, greatly saving the production cost;

[0027] 3. When the transmission shaft rotates, the driven disk rotates accordingly. At this time, the first connecting rod drives the lead screw to advance or retreat, and the threaded gear rotates forward or backward accordingly, and then pushes the rack to move towards the side close to the outer material distribution plate or the side close to the inner material distribution plate, causing the push rod to move synchronously. That is, the push rod pushes the workpiece in the punching die into the tapping die through the chute, and the workpiece to be tapped in motion pushes the workpiece that has been tapped in its advancing direction out of the company die to complete the unloading and loading of the tapping die; By setting the appropriate lead screw thread, the rotation stroke and torque of the threaded gear can be changed. That is, after punching, the workpiece is easily adhered to the punching die due to burrs or water vapor on the workpiece, and the appropriate lead screw nut can amplify the torque, so that the workpiece in the punching die is smoothly pushed out.

Detailed implementation manners

[0034] The following further elaborates on this application Figures 1-4 in conjunction with the attached drawings.

[0035] The embodiment of this application discloses an integrated punching-tapping processing equipment for automotive parts. Referring to Figure 1 、 Figure 2 and Figure 3 , the integrated punching-tapping processing equipment for automotive parts includes a machine body 1, a conveyor belt 11, a stamping arm 12 and a tapping arm 13. The output end of the stamping arm 12 is detachably connected with a punch head 121, and the output end of the tapping arm 13 is detachably connected with a tap 131. A chassis ring 21 connected to a power source is rotatably connected to the machine body 1. An inner material distributing plate 22 is fixedly connected to the machine body 1 inside the chassis ring 21, and an outer material distributing plate 23 is fixedly connected to the machine body 1 outside the chassis ring 21. Two punching dies 31 are fixedly connected to the chassis ring 21 and are evenly distributed. The tops of the inner material distributing plate 22 and the outer material distributing plate 23 on the side far from the punch head 121 are both fixedly connected with tapping dies 32. There are two tapping arms 13, which are respectively located above the two tapping dies 32. Each tapping arm 13 has two taps 131, and one stamping arm 12 has two punch heads 121. Both ends of the punching die 31 and the tapping die 32 in the radial direction of the chassis ring 21 are open. When the chassis ring 21 is in a static state, the two tapping dies 32 and the two punching dies 31 are collinear. A waste opening is formed in the chassis ring 21 below the punching die 31. A transfer assembly 4 for transferring the workpiece 9 in the punching die 31 located between the two tapping dies 32 to one of the tapping dies 32 is arranged on the machine body 1, and a loading assembly 5 for transferring the workpiece 9 on the conveyor belt 11 to the punching die 31 located under the punch head 121 is also arranged on the machine body 1. A driving assembly 6 for driving the transfer assembly 4 and the loading assembly 5 is further arranged on the machine body 1. In the embodiment of this application, there are two groups of driving assemblies 6, that is, the two groups of driving assemblies 6 respectively drive the loading assembly 5 and the transfer assembly 4.

[0036] The conveyor belt conveys the workpiece 9 to the punching die 31. The driving assembly 6 drives the feeding assembly 5 to make the workpiece 9 enter the punching die 31. Then the punching arm 12 presses down to punch a hole in the workpiece 9 with the punch 121. The waste material falls from the waste outlet. Then the punching arm 12 moves up to disengage the punch 121 from the workpiece 9. Then the chassis ring 21 rotates to the position where the punching die 31 faces the tapping die 32. The driving assembly 6 drives the transfer assembly 4 to move the workpiece 9 into the tapping die 32 on the outer material distribution plate 23. Then the tapping arm 13 drives the tap 131 to perform tapping operation. During the tapping operation, the chassis ring 21 rotates to drive another punching die 31 to move to the feeding assembly 5 for feeding and punching operations. After the punching is completed, the chassis ring 21 rotates to move the punching die 31 to the position facing the tapping die 32. Then the transfer assembly 4 moves the workpiece 9 into the tapping die 32 on the inner material distribution plate 22. At this time, the first punching die 31 moves to the feeding assembly 5 for feeding and punching, and then moves to the tapping die 32 on the outer material distribution plate 23. The transfer assembly 4 moves the workpiece 9 in the punching die 31 towards the tapping die 32 on the outer material distribution plate 23. The moving workpiece 9 ejects the workpiece 9 in the tapping die 32, that is, the unloading is completed and the workpiece 9 to be processed in the tapping die 32 is updated at the same time. Since the punching operation is shared by two tapping stations, the waiting time required after each punching operation is greatly shortened during the whole process.

[0037] Refer to Figure 1 and Figure 2 As shown in , the driving assembly 6 includes a driving gear ring 61 fixedly connected to the circumferential wall at the bottom end of the chassis ring 21, an energy storage gear 62 rotatably connected to the machine body 1 and meshed with the driving gear ring 61, a spring 63 arranged on the energy storage gear 62, a one-way gear 64 rotatably connected to the machine body 1, and a transmission shaft 65 coaxially arranged at the end of the one-way gear 64. The one-way gear 64 is meshed with the energy storage gear 62. When the driving gear ring 61 drives the energy storage gear 62 to rotate, the energy storage gear 62 drives the one-way gear 64 to rotate idly. When the spring 63 drives the energy storage gear 62 to rotate, the one-way gear 64 drives the transmission shaft 65 to rotate synchronously. The driving gear ring 61 is also provided with a disengaging member for disengaging it from the energy storage gear 62. The disengaging member is a toothless portion 611 formed on the driving gear ring 61. There are two toothless portions 611. And when the punching die 31 moves to face the tapping die 32, the toothless portion 611 on the driving gear ring 61 faces the energy storage gear 62. The driving assembly 6 further includes a reduction box 66 connected to the output end of the transmission shaft 65.

[0038] When the chassis ring 21 rotates, the active gear ring 61 drives the energy storage gear 62 to rotate, so that the spring 63 on the energy storage gear 62 is tightened. In this process, the energy storage gear 62 drives the one-way gear 64 to rotate, but the one-way gear 64 idles and does not drive the transmission shaft 65 to rotate. When the punching die 31 on the chassis ring 21 moves to the corresponding position, the toothed portion 611 on the active gear ring 61 is opposite to the energy storage gear 62, so that the active gear ring 61 is disengaged from the energy storage gear 62, and the chassis ring 21 is temporarily stationary. The clutch disengages the driving gear from the meshing connection with the energy storage gear 62, so that the energy storage gear 62 is driven by the mainspring 63 to reverse, thereby driving the one-way gear 64 to rotate. At this time, the one-way gear 64 drives the transmission shaft 65 to rotate, and then the reduction box 66 receives the power transmitted by the transmission shaft 65. After the speed change of the reduction box 66, the reduction box 66 provides a power source with a stable rhythm for the transfer component 4 and the drive component 6. This process does not require the addition of other hardware equipment such as electronic control and corresponding software algorithms, which greatly saves production costs.

[0039] Reference Figure 2 and Figure 4 The end of the transmission shaft 65 located in the one-way gear 64 is elastically hinged with a one-way block 651. The one-way gear 64 includes an outer tooth portion 641 meshing with the energy storage gear 62 and a ratchet portion 642 meshing with the one-way block 651. When the one-way block 651 is in a free state, the one-way block 651 and the ratchet portion 642 are in a meshing state. When the one-way gear 64 is indirectly driven by the active gear ring 61, the ratchet portion 642 squeezes the one-way block 651, and the one-way block 651 reciprocates due to elasticity. At this time, the ratchet portion 642 cannot push the one-way block 651. When the one-way gear 64 is indirectly driven to rotate by the spring 63, due to the change in the rotation direction, the ratchet portion 642 pushes the one-way block 651 to rotate, thereby rotating the transmission shaft 65.

[0040] Reference Figure 2 and Figure 3 The transfer assembly 4 includes a driven plate 41 connected to the reduction box 66 through a synchronous belt, a first connecting rod 42 eccentrically hinged on the end face of the driven plate 41, a screw rod 43 slidably connected to the body 1, a threaded gear 44 rotatably connected to the body 1, a rack 45 slidably connected to the body 1 and meshing with the threaded gear 44, and a push rod 46 fixed to the rack 45 near the chassis ring 21. The end of the first connecting rod 42 away from the driven plate 41 is hinged to the end of the screw rod 43, and the threaded gear 44 is threadedly sleeved on the end of the screw rod 43 away from the first connecting rod 42. The punching die 31 is provided with a slide groove 311 that is slidably adapted to the push rod 46.

[0041] When the transmission shaft 65 rotates, the driven disk 41 rotates accordingly. At this time, the first connecting rod 42 drives the lead screw 43 to move forward or backward, and the threaded gear 44 rotates forward or backward accordingly, and then pushes the rack 45 to move towards the side close to the outer material distribution plate 23 or the side close to the inner material distribution plate 22, so that the push rod 46 also moves synchronously. That is, the push rod 46 pushes the workpiece 9 in the punching die 31 into the tapping die 32 through the chute 311, and the moving workpiece 9 to be tapped pushes the workpiece 9 that has been tapped in its advancing direction out of the company die, so as to complete the unloading and loading of the tapping die 32. At the same time, by setting a suitable thread for the lead screw 43, the rotation stroke and torque of the threaded gear 44 can be changed. That is, after punching, the workpiece 9 is easily adhered to the punching die 31 due to burrs or water vapor on the workpiece 9, etc., and a suitable lead screw 43 nut can amplify the torque, and then the workpiece 9 in the punching die 31 is smoothly pushed out.

[0042] Refer to Figure 1 and Figure 2 , the feeding assembly 5 includes a feeding rod 51 slidably connected to the machine body 1, a second connecting rod 52 hinged to one end of the feeding rod 51 away from the punching die 31, and a feeding disk 53 connected to the reduction gearbox 66 through a synchronous belt. One end of the second connecting rod 52 away from the feeding rod 51 is eccentrically hinged to the end face of the feeding disk 53. The rotation of the reduction gearbox 66 drives the feeding disk 53 to rotate, so that the second connecting rod 52 moves, and then the feeding rod 51 makes a reciprocating motion. Since the workpiece 9 needs to be quickly pushed into the die during the feeding process and then retracted to prepare for the next feeding, the movement frequency is relatively high. The simple structure of the feeding assembly 5 is more suitable for quickly reciprocating the push rod 46, and the daily maintenance such as lubrication and maintenance is also relatively simple.

[0043] Refer to Figure 1 and Figure 2 , a water permeable hole 321 is opened on the side wall of the tapping die 32, and two rows of cooling spray pipes 14 are arranged on the machine body 1, four in each row. That is, one company die corresponds to two rows of four cooling spray pipes 14. The cooling spray pipes 14 in the lower row point to the bottom end of the workpiece 9 through the water permeable hole 321, and the cooling spray pipes 14 in the upper row are located above the tapping die 32 and point to the top of the workpiece. One end of the tapping die 32 away from the punching die 31 between the two tapping dies 32 is communicated with a slideway 81, and a collection box 82 with a water filter opening is placed at the bottom of the slideway 81. During the tapping operation, the cooling spray pipes 14 in the upper row spray and cool the upper working area of the workpiece 9, and the cooling spray pipes 14 in the lower row spray and cool the lower working area of the workpiece 9 through the water permeable hole 321, thereby reducing the occurrence of sintering, jamming, chipping and other situations; after tapping, the push rod 46 pushes the workpiece 9 out of the tapping die 32, and the pushed workpiece 9 enters the slideway 81 and slides into the collection box 82 uniformly. Moreover, the coolant on the die in the collection box 82 is filtered by the water filter opening on the collection box 82 to reduce the weight of the subsequent transported workpiece 9.

[0044] Reference Figure 1 and Figure 3 At one end of the tapping die 32 away from the push rod 46, an elastic retaining piece 7 is fixedly connected. The elastic retaining piece 7 can be made of rubber or spring steel. In this application, the elastic retaining piece 7 is made of spring steel with a low coefficient of friction and higher durability. When the elastic retaining piece 7 is in a natural state, the elastic retaining piece 7 fits against the workpiece 9 inside the tapping die 32. At one end of the punching die 31 at the punch 121 away from the feeding rod 51, an elastic retaining piece 7 is also fixedly connected. When the push rod 46 pushes the workpiece 9 into the tapping die 32, the elastic retaining piece 7 resists the workpiece 9 to prevent the workpiece 9 from sliding due to inertia to a position where the workpiece 9 to be tapped is not aligned with the tap 131. That is, the elastic retaining piece 7 on the tapping die 32 effectively reduces the error during tapping. Similarly, the elastic retaining piece 7 on the punching die 31 also reduces the error during punching operation.

[0045] The implementation principle of an automotive part punching-tapping integrated processing device according to an embodiment of the present application is as follows: When the chassis ring 21 rotates, the driving gear ring 61 drives the energy storage gear 62 to rotate, causing the spring 63 on the energy storage gear 62 to wind up and store energy. During this process, the energy storage gear 62 drives the one-way gear 64 to rotate, but the one-way gear 64 idles and does not drive the transmission shaft 65 to rotate;

[0046] When the chassis ring 21 rotates to align the punching die 31 with the tapping die 32, the chassis ring 21 undergoes a brief stop. At this time, the disengaging member disengages the driving gear from the meshing connection with the energy storage gear 62, causing the energy storage gear 62 to reverse under the drive of the spring 63 to drive the one-way gear 64 to rotate. The one-way gear 64 then drives the transmission shaft 65 to rotate. At this time, the reduction gearbox 66 drives the driven disk 41 to rotate, and the first connecting rod 42 drives the lead screw 43 to advance or retreat. The threaded gear 44 then rotates forward or backward accordingly, and further pushes the rack 45 to move towards one side close to the outer material distribution plate 23 or one side close to the inner material distribution plate 22, causing the push rod 46 to move synchronously. That is, the push rod 46 pushes the workpiece 9 in the punching die 31 into the tapping die 32 through the chute 311, and the moving workpiece 9 to be tapped pushes the tapped workpiece 9 in its advancing direction out of the company die to complete the unloading and feeding of the tapping die 32. At the same time, the reduction gearbox 66 drives the feeding disk 53 to rotate, causing the second connecting rod 52 to move, and further causing the feeding rod 51 to perform a reciprocating motion to push the workpiece 9 into the punching die 31 and then retreat.

[0047] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
