Description

Technical Field

[0001] The present invention belongs to the technical field of automobile parts manufacturing, and more specifically, relates to a processing device for automobile parts. Background Art

[0002] Cars are a common means of transportation, assembled from multiple parts. Among them, the clutch friction plate is a crucial component in transmitting power. The overall shape of the clutch friction plate is disc-shaped. During machining, the clutch friction plate needs to be placed on equipment for drilling. With technological advancements, suitable tooling has been developed to secure the plate during construction, allowing for simultaneous drilling of multiple clutches.

[0003] For example, the prior art with publication number CN118617159A discloses a tool for processing automobile clutch friction plates, which belongs to the technical field of clutch friction plate processing. The technical points are: it includes a workbench, and the friction plate clamping mechanism is set up, which can not only realize the limit clamping of the inner ring of the friction plate to be processed, but also realize the clamping limit of the outer ring of the friction plate to be processed accordingly, thereby realizing good clamping and fixing of the friction plate to be processed, facilitating batch processing operations, reducing production costs, and improving work efficiency. In addition, the set work station rotation switching mechanism can drive the clamped and fixed friction plate to be processed to perform rotation drilling and reaming processing without manual rotation.

[0004] Clutch friction plates have specific flatness requirements. After casting, they are typically inspected for flatness using a surface inspection instrument, and then punched. However, after transport, the plates may become non-flat again due to issues like squeezing or falling during transportation. This can be difficult to detect, hindering assembly of the clutch disc after drilling. The aforementioned existing machining device cannot determine the flatness of the plates when drilling, resulting in drilling into uneven workpieces. This results in wasted parts, unnecessary processing costs, and reduced efficiency. Summary of the Invention

[0012] Preferably, a fixed column is fixed to the upper end of the base, and the fixed column and the base are coaxially arranged. A plurality of inner ring tightening blocks are slidably connected to the fixed column along the radial direction of the base, and a gap is left between the lower side of the inner ring tightening block and the base.

[0013] Preferably, the surface of the base plate is connected with a plurality of vertical rods for sliding movement along the vertical direction, the vertical rods are located below the inner ring clamping block, a mounting rod is fixed below the outer ring clamping ring, a connecting rod is provided below the mounting rod, a fourth inclined surface is provided on the connecting rod, and the lower end of the vertical rod can act on the fourth inclined surface to push the connecting rod inward.

At this time, the staff can know that the clutch friction plate is a waste part, avoiding processing of workpieces whose flatness does not meet the standard and preventing invalid processing.

[0035] The embodiments of the present invention are intended to introduce and illustrate the structural composition of a processing device for automobile parts and the coordination relationship between the various components. Unless otherwise specified, the dimensions, materials, and manufacturing processes of the various components in the processing device suitable for automobile parts in the embodiments of the present invention can be selected according to specific circumstances and are not specifically limited or explained here.

[0036] Furthermore, in order to provide the public with a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.

[0037] Example 1 Reference Figure 1 and 2The present invention provides an automobile parts processing device, including a support table 1, a processing component 2, a first drive component 3, a second drive component 4, a friction plate clamping component 5, a trigger component 6 and a drive connection component 7. The support table 1 is fixed to a workbench or the ground, and is the positioning basis of the entire processing device. The friction plate clamping component 5 is used to position the clutch friction plate 8, and the processing component 2 performs drilling processing on the clutch friction plate 8. The first drive component 3 can drive the friction plate clamping component 5 to rotate itself, and the second drive component 4 can drive the friction plate clamping component 5 to rotate in a circular direction on the support table 1. The friction plate clamping component 5, the trigger component 6 and the drive connection component 7 will cooperate with each other to realize the transmission or disconnection of the driving force of the first drive component 3. The processing component 2 is a prior art, and the specific model selection and structure are not limited. Its structure will not be repeated in this application.

[0038] Reference Figure 3 The friction plate clamping assembly 5 includes a rotating shaft 51, a base plate 52, an inner ring abutment block 53, and an outer ring abutment ring 54. The rotating shaft 51 is fixed below the base plate 52. The upper surface of the base plate 52 is flat. Multiple inner ring abutment blocks 53 and outer ring abutment rings 54 are provided. Both the inner ring abutment blocks 53 and the outer ring abutment ring 54 can slide radially along the base plate 52. A retaining groove 541 is defined on the inner side of the outer ring abutment ring 54. The height of the retaining groove 541 is the same as the thickness of the clutch friction plate 8. The lower surface of the retaining groove 541 and the upper surface of the base plate 52 are coplanar. It should be noted that the height of the retaining groove 541 does not have to be exactly the same as the thickness of the clutch friction plate 8. The thickness of the retaining groove 541 can be appropriately increased within the tolerance range of the flatness of the clutch friction plate 8. For example, the tolerance of the clutch friction plate 8 is generally required to be no greater than 0.5 mm. Therefore, the height of the retaining groove 541 can differ from the thickness of the clutch friction plate 8 by within a range of 0.5 mm.

[0039] When the clutch friction plate 8 is fixed above the base plate 52 and is ready for machining, the lower surface of the clutch friction plate 8 and the upper surface of the base plate 52 are aligned with the outer circumference of the inner ring abutment block 53, while the outer ring abutment ring 54 moves inward. If the clutch friction plate 8 meets the required flatness, the clutch friction plate 8 can be inserted into the retaining groove 541 with the lower side of the clutch friction plate 8 in contact with the base plate 52. If the clutch friction plate 8 is not flat enough, the clutch friction plate 8 cannot smoothly enter the retaining groove 541, and one or more outer ring abutment rings 54 will not be able to move smoothly inward.

[0040] The rotating shaft 51 and the output shaft of the first drive assembly 3 are rotatably connected to each other, so that the first drive assembly 3 cannot directly drive the rotating shaft 51 to rotate to complete the processing. The drive connection assembly 7 is connected to the output shaft of the first drive assembly 3, and the drive connection assembly 7 can be connected or disconnected with the rotating shaft 51. This allows power input between the rotating shaft 51 and the first drive assembly 3 through the drive connection assembly 7. When the outer ring abutting ring 54 moves inward until the clutch friction plate 8 is engaged in the card slot 541, the trigger assembly 6 can trigger the drive connection assembly 7 as the outer ring abutting ring 54 moves inward, so that the drive connection assembly 7 is connected to the rotating shaft 51, completing the power input.

[0041] When the clutch friction plate 8 is processed and the clutch friction plate 8 is moved onto the base plate 52, the inner ring abutting block 53 can, on the one hand, abut the inner side of the clutch friction plate 8, and on the other hand, determine the basic position of the clutch friction plate 8. At this time, the lower side of the clutch friction plate 8 abuts against the horizontal surface on the base plate 52. If the levelness of the clutch friction plate 8 is intact, the outer ring abutting ring 54 moves inward to clamp the clutch friction plate 8 into the clamping groove 541. In this state, the trigger assembly 6 can be driven to move the drive connecting assembly 7 and connect to the rotating shaft 51, so that the first drive assembly 3 can The clutch friction plate 8 can be punched by applying power to the rotating shaft 51 normally, so that the base plate 52 can rotate. However, if the flatness of the clutch friction plate 8 is not good, the inward movement of one or more outer rings 54 will be blocked, and the drive connection component 7 will be difficult to be activated by the trigger component 6. The power of the first drive component 3 will be difficult to input to the rotating shaft 51, resulting in the inability to complete the punching process. At this time, the staff can know that the clutch friction plate 8 is scrapped, avoiding the problem of meaningless processing of scrapped parts and the increase of meaningless processing costs. It should be noted that the inward movement is moving toward the center of the base plate 52, while the outward movement is moving away from the center of the base plate 52.

[0042] Reference Figure 4 and Figure 5 As an embodiment, the drive connection assembly 7 includes a fixed cylinder 71, a sliding sleeve 72, and a first telescopic rod 73. The fixed cylinder 71 is fixedly connected to the output shaft of the first drive assembly 3. Multiple first telescopic rods 73 are provided, one end of each of the multiple first telescopic rods 73 is fixed to the fixed cylinder 71, and the end of the first telescopic rod 73 away from the fixed cylinder 71 is fixed to the sliding sleeve 72. The sliding sleeve 72 is a square cylinder with a rotating ring 721 rotatably provided on the outer periphery of the sliding sleeve 72. The rotating ring 721 is coaxially arranged with the base plate 52. A square annular groove 511 is provided on the lower side of the rotating shaft 51, and the sliding sleeve 72 can be inserted into the square annular groove 511.

[0043] The drive connection assembly 7 has a connected state and a disconnected state. In the connected state, the sliding sleeve 72 is inserted into the square annular groove 511, while in the disconnected state, the sliding sleeve 72 is disengaged from the square annular groove 511. In the connected state, the output shaft of the first drive assembly 3 rotates, thereby driving the fixed cylinder 71 to rotate, and further driving the rotating shaft 51. In the disconnected state, the output shaft of the first drive assembly 3 rotates only the sliding sleeve 72 and the fixed cylinder 71, and cannot transmit drive to the rotating shaft 51.

[0044] The trigger assembly 6 includes a vertical moving rod 61 and a horizontal push rod 62. The vertical moving rod 61 can move up and down, and the horizontal push rod 62 and the outer ring tightening ring 54 can be indirectly connected. During the movement of the horizontal push rod 62 toward the inside, it can push the vertical moving rod 61 to move upward. A shift rod 63 is fixed to one side of the vertical moving rod 61. When the vertical moving rod 61 moves upward, it can drive the shift rod 63 to move upward, and can drive the drive connection assembly 7 to switch to the connected state, so that the base plate 52 can rotate; on the contrary, when the drive connection assembly 7 is in the disconnected state, the base plate 52 will not be able to rotate, and the clutch friction plate 8 cannot be punched.

[0045] As an example, refer to Figure 1 and Figure 2 The support platform 1 has a circular groove 11 on its surface. A transposition ring 12 is rotatably connected to the groove 11. The first drive assembly 3 is fixed to the transposition ring 12. The output shaft of the first drive assembly 3 extends to the upper side of the transposition ring 12 and is connected to the friction plate clamping assembly 5. An internal gear ring 13 is fixed to the inner side of the transposition ring 12. The first drive assembly 3 and the second drive assembly 4 are both motors. The second drive assembly 4 is fixed to the bottom of the support platform 1. A gear 14 is fixed to the output shaft of the second drive assembly 4. The gear 14 meshes with the internal gear ring 13, driving the transposition ring 12 to rotate, thereby driving the multiple friction plate clamping assemblies to change positions.

[0046] A travel switch (not shown) is disposed within the rotating shaft 51. The travel switch contacts are disposed within the square annular groove 511. When the sliding sleeve 72 slides and contacts the travel switch, it can transmit a power-on signal to the second drive assembly 4. Only when multiple travel switches transmit power-on signals can the second drive assembly 4 be energized. Specifically, the second drive assembly 4 can only operate and be energized when the drive connection assembly 7 is in the connected state. When the drive connection assembly 7 is in the disconnected state, the second drive assembly 4 cannot provide power to rotate the shift ring 12. If the clutch friction plate 8 is not sufficiently flat, the friction plate clamping assembly 5 will not rotate independently, making it difficult to transfer the workstation. It is understood that the travel switch can be a wireless travel switch. The structure and method for transmitting power-on signals by a travel switch or wireless travel switch are well known to those skilled in the art and will not be further described in this application.

[0047] Reference Figure 5 As an embodiment, a first spring 731 is sleeved on the outside of the first telescopic rod 73, and both ends of the first spring 731 are respectively fixed between the sliding sleeve 72 and the fixed cylinder 71. Under normal circumstances, the first spring 731 can push the sliding sleeve 72 to be inserted into the square ring groove 511.

[0048] Reference Figure 4 The vertical moving rod 61 includes a first rod body 611 and a second rod body 612. The first rod body 611 and the second rod body 612 can slide relative to each other in the vertical direction. The first rod body 611 and the second rod body 612 are connected by a plurality of second springs 64. The elastic coefficient of the second spring 64 is greater than the elastic coefficient of the first spring 731. The first rod body 611 is slidably connected to the base plate 52 in the vertical direction. The shifting rod 63 is fixed to the second rod body 612. The shifting rod 63 abuts against the upper side of the rotating ring 721. The upper side of the first rod body 611 The end extends to the inner side of the inner ring tightening block 53, and the upper end of the first rod body 611 is provided with a first inclined surface 613. When the inner ring tightening block 53 is engaged with the clutch friction plate 8, it can move inward to contact the first inclined surface 613 until the lower side of the inner ring tightening block 53 is against the top of the first rod body 611. In this process, the entire vertical moving rod 61 is pushed downward and the position of the vertical moving rod 61 is limited, thereby pushing the rotating ring 721 to move, compressing the first spring 731 and maintaining this state, thereby keeping the drive connection assembly 7 in the disconnected state.

[0049] A trigger groove 614 is provided on the outer side of the second rod body 612, and the horizontal push rod 62 can be inserted into the trigger groove 614. A second inclined surface 615 is provided on the upper side of the trigger groove 614. The outer side of the second inclined surface 615 is inclined upward relative to the inner side. When the outer ring tightening ring 54 moves inward, it can push the horizontal push rod 62 to move inward. The horizontal push rod 62 can push the second inclined surface 615, and then compress and push the second rod body 612 to compress the second spring 64 to move upward, which can drive the shift rod 63 to move upward away from the rotating ring 721. The rotating ring 721 and the sliding sleeve 72 lose their restrictions, and the first spring 731 can return to normal, pushing the sliding sleeve 72 to move upward, and restoring the drive connection assembly 7 to the connected state.

[0050] The solution provided by this embodiment is that when the clutch friction plate 8 is not placed in the friction plate clamping assembly 5, the first spring 731 can maintain the drive connection assembly 7 in a connected state. When the clutch friction plate 8 is placed, the clutch friction plate 8 can first cooperate with the inner ring clamping block 53, so that the inner ring clamping block 53 moves inward, and the inner ring clamping block 53 is engaged with the inner ring where the clutch friction plate 8 is placed, pushing the entire vertical moving rod 61 to move downward and limiting the position of the vertical moving rod 61, keeping the drive connection assembly 7 in a disconnected state. As the outer ring clamping ring 54 moves inward and cooperates with the clutch friction plate 8, if the clutch friction plate 8 meets the requirements and can be engaged in the clamping groove 541, when the outer ring clamping ring 54 moves inward, it can push the horizontal push rod 62 to move inward, and can drive the dial rod 63 to move upward away from the rotating ring 721, so that the drive connection assembly 7 is restored to a connected state. The functions that can be achieved are: if the clutch friction plate 8 is not installed in the friction plate connecting assembly and the drive connecting assembly 7 is not connected, it will not affect the operation of the second drive assembly 4 and the operation of the entire automobile processing device; and only after the clutch friction plate 8 and the inner ring tightening block 53 are in contact, the drive connecting assembly 7 will be disconnected, and the flatness of the clutch friction plate 8 can be judged.

[0051] Reference Figure 3 and Figure 4 As an embodiment, a fixing post 521 is fixed to the upper end of the base plate 52. The fixing post 521 and the base plate 52 are coaxially arranged. Multiple inner ring abutment blocks 53 are circumferentially arranged around the fixing post 521. The inner ring abutment blocks 53 are slidably connected to one side of the fixing post 521 along the radial direction of the base plate 52, leaving a gap between the lower side of the inner ring abutment blocks 53 and the base plate 52. A third spring 522 is fixed between the fixing post 521 and the inner ring abutment blocks 53. A third inclined surface 531 is defined on the upper side of the inner ring abutment blocks 53. The outer circumference of the inner ring abutment blocks 53 is an arcuate surface. When installing the clutch friction plate 8, it can be pushed in from top to bottom. The clutch friction plate 8 contacts the third inclined surface 531, pushing the inner ring abutment blocks 53 inward, causing the inner ring abutment blocks 53 to abut the inner side of the clutch friction plate 8, thereby achieving initial positioning of the clutch friction plate 8.

[0052] The surface of the base plate 52 is connected with multiple vertical rods 523 for sliding movement along the vertical direction. The position of the vertical rods 523 is located below the position of the inner ring clamping block 53 when the third spring 522 is in the normal state. When the inner ring of the clutch friction plate 8 abuts against the outer periphery of the inner ring clamping block 53, it can continue to move downward to force the vertical rods 523 to move downward.

[0053] A mounting rod 542 is fixed below the outer ring tightening ring 54 , and the mounting rod 542 is slidably connected to the side of the base plate 52 along the radial direction of the base plate 52 . A connecting rod 543 is fixed to the lower side of the mounting rod 542 , so that the connecting rod 543 is also slidably connected to the bottom of the base plate 52 . A fourth inclined surface 544 is provided above the connecting rod 543. The fourth inclined surface 544 can contact the lower end of the vertical rod 523. When the vertical rod 523 moves downward, it presses the fourth inclined surface 544, causing the connecting rod 543 to move inward, thereby driving the outer ring clamping ring 54 to move inward. When installing the clutch friction plate 8, the clutch friction plate 8 can first push the inner ring clamping block 53 inward to press against the inner side of the clutch friction plate 8, turning the drive connection assembly 7 from the connected state to the disconnected state. Then, further downward movement triggers the vertical rod 523 to push the outer ring clamping ring 54 inward. Whether the clutch friction plate 8 can be engaged with the slot 541 of the outer ring clamping ring 54 determines whether the drive connection assembly 7 is turned into the connected state again. Furthermore, the push rod 62 is fixed below the connecting rod 543 so that the push rod 62 can move synchronously with the outer ring clamping ring 54.

[0054] Reference Figure 6 and Figure 7 As an embodiment, the positional relationship between the outer ring abutting ring 54 and the clutch friction plate 8 has a first state and a second state, wherein the first state is the inner circumference abutting state of the clutch friction plate 8 and the outer ring abutting ring 54; the second state is the state in which the clutch friction plate 8 is engaged in the card groove 541.

[0055] The connecting rod 543 comprises an active rod 545 and a passive rod 546, which are capable of relative movement along the radial direction of the base plate 52. Specifically, a rod body can be fixed to the active rod 545, which can be inserted into the guide 546. This is a conventional structure and will not be described in detail here. The passive rod 546 is fixed to the vertical rod 523, and the horizontal push rod 62 is also fixed to the passive rod 546. The active rod 545 and the passive rod 546 are connected by a fourth spring 547, wherein the elastic coefficient of the fourth spring 547 is greater than the elastic coefficient of the second spring 64. A fourth inclined surface 544 is formed at one end of the active rod 545. When the clutch friction plate 8 gradually presses down the driven rod 546, the driven rod 546 pushes the fourth inclined surface 544, and the connecting rod 543 as a whole carries the outer ring clamping ring 54 inward. The positional relationship between the outer ring clamping ring 54 and the clutch friction plate 8 will first be in the first state. At this time, the clutch friction plate 8 continues to move downward to push the vertical rod 523, and the outer ring clamping ring 54 cannot continue to move inward. The vertical rod 523 pushes the fourth inclined surface 544 to make the active rod 545 continue to move inward and stretch the fourth spring 547. Until the clutch friction plate 8 moves to the same plane as the slot 541 and the flatness meets the standard, the fourth spring 547 loses its restriction and returns to normal, which will push the driven rod 546 to carry the vertical rod 523 and the outer ring clamping ring 54 inward, pushing the positional relationship between the clutch friction plate 8 and the outer ring clamping ring 54 to the second state.

[0056] Reference Figure 3 As an embodiment, an avoidance groove 616 is provided on one side of the vertical moving rod 61, and the active rod 545 can be pushed into the avoidance groove 616, and the upper end of the vertical rod 523 moves to be flush with the upper surface of the base plate 52, and the end of the active rod 545 can abut against the side wall of the avoidance groove 616. A guide piece 617 is fixed in the avoidance groove 616, and a sheet-shaped groove 5451 is provided at the end of the active rod 545, and the sheet-shaped groove 5451 can be inserted into the guide piece 617. The avoidance groove 616 can make way for the movement of the active rod 545, and the cooperation between the guide piece 617 and the sheet-shaped groove 5451 can make the movement of the active rod 545 stable.

[0057] Reference Figure 8As an embodiment, a sleeve 5461 is fixed to the upper side of the driven rod 546. A fifth spring 5462 is fixed along the sleeve 5461. A clamping joint 5463 is fixed to the upper end of the fifth spring 5462. The clamping joint 5463 can abut the lower surface of the receiving plate. The lower surface of the base plate 52 is provided with a positioning groove 524, and the clamping joint 5463 can be clamped into the positioning groove 524. As the driven rod 546 moves, the clamping joint 5463 moves inward to the position of the positioning groove 524, and the clamping joint 5463 rebounds upward into the positioning groove 524, thereby positioning the outer ring 54 in the horizontal direction, thereby fixing the outer ring 54 and ensuring that the clutch friction plate 8 is stably mounted on the base plate 52.

[0058] Reference Figure 9 Furthermore, an annular groove 525 is provided in the base plate 52, and an annular piece 526 is connected to the annular groove 525 for sliding in the vertical direction. A plurality of insertion rods 5261 are fixed to the lower end of the annular piece 526, and the insertion rods 5261 can be inserted into the positioning groove 524. A cylindrical groove 5211 is provided in the middle of the fixing column 521, and the cylindrical groove 5211 and the annular groove 525 can be connected. A switch 5212 is inserted in the cylindrical groove 5211, and the switch 5212 can be fixed to the annular piece 526. The lower side of the annular piece 526 can press the card joint 5463. The positional relationship between the outer ring clamping ring 54 and the clutch friction plate 8 is that in the second state, each clamping column passes through the positioning groove 524 and is clamped in the annular groove 525. When the switch 5212 is pressed down, the insertion rod 5261 can push the clamping column out of the positioning groove 524. At this time, multiple outer ring clamping rings 54 are pushed outward synchronously and the fourth spring 547 is stretched. When the clamping groove 541 of the outer ring clamping ring 54 and the clutch friction plate 8 are disengaged, the fourth spring 547 will pull the active rod 545 to push the vertical rod 523 upward to pop out the clutch friction plate 8, completing the removal of the clutch friction plate 8.

[0059] As an embodiment, a plurality of electric push rods 527 are fixed to the side periphery of the base plate 52, and a pressure plate 5271 is fixed to the end of the telescopic rod of the electric push rod 527. The pressure plate 5271 can abut against the mounting rod 542, and then can push the outer ring clamping ring 54 to move, making operation convenient.

[0060] Reference Figure 3A plurality of guide rods 528 are fixed to the side periphery of the base plate 52. The vertical rods 523 are inserted through the guide rods 528, and the guide rods 528 serve as guides for the movement of the vertical rods 523. A positioning piece is fixed to the end of the guide rod 528. A sixth spring 5281 is fixed between the positioning piece and the vertical rod 523. The elastic coefficient of the sixth spring 5281 is smaller than that of the first spring 731. The sixth spring 5281 only serves to reset the vertical rod 523. When the electric push rod 527 moves the vertical rod 523 outward, the sixth spring 5281 pulls the vertical rod 523, the connecting rod 543, and the outer ring retaining ring 54 back to their initial state, ready for the next loading process.

[0061] The implementation principle of the present invention is as follows: when processing the clutch friction plate 8, multiple clutch friction plates 8 are moved onto the base plate 52, and the inner ring tightening block 53 first contacts the clutch friction plate 8 and moves inward. This process triggers the vertical moving rod 61 to move downward, transferring the drive connection assembly 7 to the disconnected state, and disconnecting the power of the second drive assembly 4. As the clutch friction plate 8 gradually moves downward, the clutch friction plate 8 presses the vertical rod 523, pushing the connecting rod 543 as a whole to drive the outer ring tightening ring 54 to move to the first state, and continuing to move the clutch friction plate 8 downward can stretch the fourth spring 547 until the clutch friction plate 8 enters the range of the card groove 541. At this time, if the flatness of the clutch friction plate 8 meets the standard, the fourth spring 547 returns to normal and can move the outer ring tightening ring 54, locking the clutch friction plate 8 into the card groove 541. In this process, it can push the horizontal moving rod to trigger the second rod body 612 to move upward, and transfer the drive connection assembly 7 to the connected state, so that the part processing device can perform punching processing.
