Description

Technical Field

[0001] The utility model mainly relates to the technical field of automotive friction plates, and particularly relates to a general-purpose friction plate riveting device. Background Art

[0002] Automotive brake friction plates are crucial safety components in the automotive braking system, and their structural composition involves multiple key parts to ensure effective braking performance and safety.

[0003] The structural composition of automotive brake friction plates mainly includes friction materials, heat insulation layers, adhesive layers, and back plates. When manufacturing automotive brake friction plates, in order to improve the structural strength after connecting all materials, it is necessary to stack all materials together for riveting operations.

[0004] Currently, the existing friction plate riveting devices are generally divided into two types. One is fully automatic riveting. When riveting, rivets are placed in all the connecting holes of the friction plate, and it is formed by a single press of a mold. This is suitable for a large number of general friction plate riveting operations and has high work efficiency.

[0005] There is also another type suitable for a small number of friction plate riveting operations, that is, the common manual riveting machine, which requires manual riveting of each connecting hole one by one.

[0006] The inventor found the following defects during the operation of specific embodiments:

[0007] For fully automatic riveting, corresponding molds need to be made during production to perform a one-time pressing operation. The price of the molds is relatively high, and the corresponding molds can only be made for friction plates of corresponding specifications. If new specifications of friction plates in small batches are produced, new molds need to be customized, and the waiting time is relatively long. Although the manual riveting machine can adapt to friction plates of different sizes, the manual work intensity is high and the efficiency is low.

[0008] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0009] 1. Technical problems to be solved by the utility model:

[0010] The utility model provides a general-purpose friction plate riveting device to solve the technical problems existing in the above background art.

[0011] 2. Technical solutions:

[0012] To achieve the above object, the technical solution provided by the present utility model is: a general-purpose friction plate riveting device, including a workbench. On one side of the top of the workbench, there is a riveting machine. In the middle of the workbench, there is a lifting cylinder. The top of the lifting cylinder is connected to a position adjusting plate. The top of the position adjusting plate is provided with a sliding groove, which is connected to a moving block in a matching manner. The top of the moving block is connected to a rotating base, and the top of the rotating base is connected to a clamping device. The clamping device is connected to the friction plate. At the bottom of the riveting machine, there is a fixed block, and the top of the fixed block is detachably connected to a riveting tooling. When the device works, the friction plate components to be processed are first stacked together and preliminarily connected through an adhesive layer. Then, the friction plate components are placed into the clamping device, and the clamping device positions the friction plate components. Subsequently, the position of the moving block is adjusted to align the connection holes of the friction plate components with the clamping device. The riveting machine adopts existing technologies, and can be a manual riveting machine or an automatic feeding riveting machine, which will not be elaborated here. During operation, a rivet is connected to the pressing needle of the riveting machine, and the lifting cylinder at the bottom moves the connection hole downward to connect the connection hole with the riveting tooling. Subsequently, the riveting machine presses the rivet downward into the connection hole, thereby connecting the rivet to the friction plate. Then, the lifting cylinder raises the friction plate to separate the connection hole from the riveting tooling. By rotating a preset angle through the rotating base (the rotating base adopts existing technologies and will not be elaborated here), the next connection hole is aligned with the riveting tooling, waiting for the next round of riveting operation. The moving block of this device can adjust the distance between the friction plate and the riveting customization, and can adapt to the riveting operation of friction plates within a certain diameter range. There is no need to manufacture a riveting die separately, with high adaptability, and the riveting and nail driving operations are carried out in a semi-automatic manner, reducing the labor intensity.

[0013] Further, on both sides of the position adjusting plate, there are symmetrically arranged first sliding grooves, which are connected to sliding limit blocks in a matching manner. The sliding limit blocks are symmetrically arranged on the top of the workbench. Inside the sliding groove, there is a rotating lead screw, and the outside of the rotating lead screw is connected to a rotating disk. The rotating lead screw is connected to the moving block in a matching manner.

[0014] Further, the clamping device includes a lower base plate. The top of the lower base plate is provided with a threaded groove, and the threaded groove is detachably connected to an upper clamping block through a screw.

[0015] Further, on both sides at the bottom of the upper clamping block, there are sliding connections with lower pressing plates. At both ends of the upper clamping block, there are locking grooves, and locking screws are arranged inside the locking grooves.

[0016] Further, the riveting tooling includes a riveting punch sleeve. The bottom of the riveting punch sleeve is detachably connected to a riveting nut. The top of the riveting nut is connected to a thimble spring, and the top of the thimble spring is connected to a riveting thimble.

[0017] 3. Beneficial effects:

[0018] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0019] The design of the present utility model is reasonable. By using the cooperation of the clamping device and the bottom position adjusting plate, the position of friction plates with different specifications and diameters can be adjusted so that the connection holes on their peripheries are aligned with the riveting operation. Then, through the rotating base at the bottom, the friction plates are rotated at intervals to achieve semi-automatic riveting operation, with a wide adaptation range and improved riveting efficiency.

[0020] It should be noted that the structures not introduced in the present utility model, since they do not involve the design key points and improvement directions of the present utility model, are the same as the prior art or can be implemented by using the prior art, and will not be elaborated herein.

[0032] Refer to the attached Figures 1-5, A general-purpose friction plate riveting device, including a workbench 1. On one side of the top of the workbench 1, there is a riveting machine 2. In the middle of the workbench 1, there is a lifting cylinder 3. The top of the lifting cylinder 3 is connected to a position adjustment plate 4. The top of the position adjustment plate 4 is provided with a sliding groove 5. The sliding groove 5 is connected to a moving block 6 in a matching manner. The top of the moving block 6 is connected to a rotating base 7. The top of the rotating base 7 is connected to a clamping device 8. The clamping device 8 is connected to the friction plate. At the bottom of the riveting machine 2, there is a fixed block. The top of the fixed block is detachably connected to a riveting tooling 9. When this device works, the friction plate components to be processed are first stacked together and preliminarily connected through an adhesive layer. Then, the friction plate components are placed into the clamping device 8. The clamping device 8 positions the friction plate components. Then, the position of the moving block 6 is adjusted so that the connection holes of the friction plate components are aligned with the clamping device 8. The riveting machine 2 adopts the existing technology and can be a manual riveting machine 2 or an automatic feeding riveting machine 2, which will not be elaborated here. When working, a rivet is connected to the pressure pin of the riveting machine 2. The lifting cylinder 3 at the bottom moves the connection hole downward so that the connection hole is connected to the riveting tooling 9. Then, the riveting machine 2 presses the rivet downward into the connection hole, thereby connecting the rivet to the friction plate. Then, the lifting cylinder 3 raises the friction plate so that the connection hole is separated from the riveting tooling 9. By rotating the rotating base 7 by a preset angle (the rotating base 7 adopts the existing technology and will not be elaborated here), the next connection hole is aligned with the riveting tooling 9, waiting for the next round of riveting operation. The moving block 6 of this device can adjust the distance between the friction plate and the riveting customization, can adapt to the riveting operation of friction plates within a certain diameter range, does not require additional production of riveting molds, has high adaptability, and adopts a semi-automatic method for riveting and nailing operations, reducing labor intensity.

[0033] On both sides of the position adjustment plate 4, there are symmetrically arranged first sliding grooves 41. The first sliding grooves 41 are connected to sliding limit blocks 42 in a matching manner. The sliding limit blocks 42 are symmetrically arranged on the top of the workbench 1. Inside the sliding groove 5, there is a rotating lead screw 43. The outside of the rotating lead screw 43 is connected to a rotating disk 44. The rotating lead screw 43 is connected to the moving block 6 in a matching manner. When riveting friction plates with different diameters, it is necessary to first fix the friction plate by the clamping device 8. Then, rotate the rotating disk 44, which drives the rotation of the rotating lead screw 43, thereby driving the clamping device 8 at the top to move back and forth, so that the connection holes of friction plates with different specifications are aligned with the riveting tooling 9.

[0034] The clamping device 8 includes a lower bottom plate 81. On the top of the lower bottom plate 81, there is a threaded groove. The threaded groove is detachably connected to an upper clamping block 82 through a screw.

Locking grooves 84 are formed at both ends of the upper clamping block 82, and locking screws 85 are arranged in the locking grooves 84. In order to improve the adaptability of the upper clamping block 82, the slidable lower pressing plate 83 is provided. When the diameter of the friction plate is relatively large, the lower pressing plate 83 can be pulled outwards by a certain distance, and then the lower pressing plate 83 is positioned by the locking screw 85. Subsequently, the upper clamping block 82 is connected to the lower bottom plate 81 through screws.

[0036] The riveting tooling 9 includes a riveting punch sleeve 91. The bottom of the riveting punch sleeve 91 is detachably connected to a riveting nut 92.

When riveting, the bottom of the rivet will be extruded by the riveting punch sleeve 91, so that the bottom of the rivet warps outwards to form a rivet joint. The telescopic riveting thimble 94 plays a guiding role.

[0037] The above embodiments only represent a certain implementation mode of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
