Description

Technical Field

[0001] This application relates to the field of ball pin processing technology, and more specifically, to a ball pin processing device. Background Technology

[0002] Ball pins are components used in automotive steering systems.

[0003] For example, Chinese invention patent CN110883283B discloses a manufacturing process for ball pins, relating to the field of metal parts manufacturing technology, including the following steps: Step S1: Forging a ball head from a cylindrical blank; Step S2: Forging an annular groove using tooling and a hydraulic cylinder, the tooling including mold one and mold two rotatably connected to the machine frame, forming a cavity between mold one and mold two, which are interlocked left and right; Step S21: Inserting the ball head of the ball pin into the cavity; Step S22: Forging mold one and mold two using two forming cylinders respectively; the forming cylinders repeatedly extend and retract multiple times; Step S3: Turning the surface of the ball pin; Step S4: Heat treatment. This process uses forging to complete the processing of the annular groove, greatly enhancing the strength of the ball pin located in the annular groove.

[0004] In the actual processing, because the end of the ball pin rod away from the ball head is clamped, and the forming cylinder pushes mold one and mold two respectively to forge the part to be processed of the ball pin head, there is a situation where the ball pin head vibrates and shifts. This situation affects normal processing and needs to be improved. Summary of the Invention

[0005] To improve the problem of vibration and displacement of ball pins during forging, this application provides a ball pin processing device.

[0006] This application provides a ball pin processing equipment, which adopts the following technical solution:

[0007] A ball pin processing device includes a machine body, which is provided with a driving component and a driving plate. The driving component drives the driving plate to move horizontally. A clamping component is provided at the end of the driving plate opposite to the driving component, and the clamping component is used to clamp the ball pin rod portion. The machine body is provided with a control component and a linkage assembly. The control component is connected to the linkage assembly. The machine body is also provided with a first mold and a second mold, which are used for forming a ball pin annular groove. The control component drives the linkage assembly to move and cause the first mold and the second mold to press against the annular groove. The linkage assembly is connected to a clamping rod, which is used to clamp the ball pin rod portion. When the control component drives the linkage assembly to move towards the ball pin, the linkage assembly pushes the first mold and the second mold to forge the workpiece and pushes the clamping rod to clamp the ball pin rod portion.

[0008] Through the above technical solution, in the actual processing, when pushing mold one and mold two to forge the part to be processed of the ball pin head, there is a situation where the ball pin head vibrates and shifts, and there is a situation where cracks occur at the annular groove. Therefore, a linkage component is set up. The clamping rod is controlled by the linkage component so that when the linkage component pushes mold one and mold two to form the annular groove of the ball pin, it also pushes the clamping rod to assist in clamping the ball pin rod. By cooperating with the clamping component to clamp the ball pin rod, the clamping effect of the ball pin rod is improved, the vibration and shift of the ball pin head during processing is reduced, and the processing of the ball pin is facilitated.

[0009] Furthermore, the machine body includes a mounting section, the control component is disposed in the mounting section, and the linkage assembly includes a sliding plate one, a sliding plate two, and a fixed plate. The sliding plate one is located at the end of the sliding plate two away from the mold one, and the fixed plate is located on the side of the sliding plate two away from the sliding plate one. The sliding plate one and the sliding plate two slide in the mounting section, and the sliding direction of the sliding plate one and the sliding plate two is towards the mold one. The clamping rod is located at the end of the sliding plate two away from the sliding plate one. The sliding plate one is provided with a clearance hole one, the sliding plate two is provided with a sliding groove, and the bottom of the sliding groove is provided with a clearance hole two. The clearance hole one communicates with the clearance hole two. The fixed plate is provided with a guide rod, which passes through the clearance hole one and the clearance hole two. The guide rod extends in the direction close to the control component and in the direction away from the clamping component. The sliding groove extends horizontally and is perpendicular to the moving direction of the first sliding plate. A sliding block slides in the sliding groove and slides on the guide rod. The sliding direction of the sliding block is the extending direction of the guide rod. The fixed plate is provided with a processing rod, which slides on the fixed plate. The sliding direction of the processing rod is the sliding direction of the first sliding plate. The sliding block is provided with an inclined surface, which is used to abut the processing rod. When the control component pushes the first sliding plate to move, the first sliding plate drives the second sliding plate to move towards the mold. The movement of the second sliding plate causes the sliding block to move along the inclined direction of the guide rod and causes the inclined surface to abut the processing rod and push the processing rod. The moving distance of the processing rod is greater than the moving distance of the clamping rod.

[0010] Through the above technical solution, the linkage component includes a sliding plate 1, a sliding plate 2, and a fixed plate. When the control component pushes the sliding plate 1 to move, the sliding plate 1 pushes the sliding plate 2 to move closer to the mold 1, causing the sliding block to move along the inclined direction of the guide rod. The movement of the sliding block causes the inclined surface to abut against the processing rod and push the processing rod. The movement of the sliding plate 2 drives the clamping rod to move closer to the ball pin rod. Due to the existence of the inclined surface, the movement distance of the processing rod is greater than the movement distance of the clamping rod. When the processing rod abuts against the mold 1, causing the mold 1 to abut against the ball pin to be processed, the clamping rod does not clamp the ball pin rod. Subsequently, the processing rod continues to push the mold 1 to process the ball pin to be processed. At this time, because the movement distance of the processing rod is greater than the movement distance of the clamping rod, the clamping rod clamps the ball pin rod, reducing the vibration and offset of the ball pin, making the overall processing more stable.

[0011] Furthermore, the inclined surface one is located on the side of the sliding block away from the sliding plate one, and on the side of the sliding block away from the guide rod. The inclined surface one extends in the direction away from the sliding plate one towards the guide rod. When the control component pushes the linkage assembly to move towards the mold one, the inclined surface one of the sliding block abuts against the processing rod, and then the sliding block slides until the processing rod abuts against the end of the sliding block away from the sliding plate one.

[0012] With the above technical solution, the inclined surface is located on the side of the sliding block away from the sliding plate and on the side of the sliding block away from the guide rod. In actual use, as the control component pushes the sliding plate to move closer to the mold, the processing rod first contacts the inclined surface. As the sliding block moves, the contact end between the processing rod and the sliding block moves from the inclined surface to the sliding block away from the sliding plate. This makes the moving distance of the processing rod greater than the moving distance of the clamping rod during this period. The ball pin processing and clamping operations can be performed through the control component, making the overall processing more convenient.

[0013] Furthermore, the clamping rod is provided with a clamping piece, which is located at the end of the clamping rod away from the sliding plate 2. The clamping piece is provided with an elastic element, which is used to abut against the ball pin rod part. When the elastic element abuts against the ball pin rod part, mold 1 and mold 2 abut against the ball pin to be processed part.

[0014] By using the above technical solution, a clamping plate is provided, and the clamping plate is provided with an elastic element that abuts against the ball pin rod. Therefore, when the processing rod abuts against the ball pin to be processed, the elastic element abuts against the ball pin rod to clamp and fix the ball pin. As the processing rod continues to move, the clamping rod moves together, and the moving distance of the clamping rod is less than the moving distance of the processing rod. During this process, the elastic element is squeezed to further clamp the ball pin rod, thereby improving the clamping effect on the ball pin rod.

[0015] Furthermore, the processing rod includes a rod body and an abutting block. The abutting block is located at the end of the rod body away from the mold. The abutting block is provided with an inclined surface two, which is used to abut against the inclined surface one.

[0016] Through the above technical solution, in actual use, since it is necessary to push the processing rod against the mold to forge the ball pin to be processed, the inclined surface of the processing rod and the sliding block needs to bear a large pressure. Therefore, in order to reduce the wear and tear of the parts, the inclined surface is set to abut against the inclined surface, increasing the contact area between the abutting block and the sliding block, and improving the overall service life.

[0017] Furthermore, the processing rod is provided with a return element. When the sliding plate 2 moves away from the mold 1, the return element causes the processing rod to return to its original position.

[0018] In practical applications, the ball pin often needs to be forged multiple times to form an annular groove. Therefore, a recovery component is required to move the processing rod back to its original position so that subsequent forging can be carried out.

[0019] Furthermore, the first inclined surface is provided with a limiting groove, the groove wall of the limiting groove is provided with a fixing groove, the second inclined surface is provided with a limiting protrusion, the limiting protrusion is embedded in the limiting groove, the side wall of the limiting protrusion is provided with a fixing protrusion, and the fixing protrusion is embedded in the fixing groove to restrict the limiting protrusion from disengaging from the limiting groove in a direction perpendicular to the first inclined surface.

[0020] With the above technical solution, a fixed groove and a fixed protrusion are set. The fixed protrusion is used to restrict the limiting protrusion from disengaging from the limiting groove. Therefore, the movement of the sliding block will drive the movement of the processing rod. The sliding block slides on the second sliding plate. Therefore, the return of the second sliding plate will drive the processing rod to return to its original position, which is convenient for subsequent processing.

[0021] Furthermore, the machine body is equipped with a heating component, which is used to heat the ball pin to be processed part.

[0022] By using the above technical solution, a heating component is set up to process the ball pin part, which facilitates the processing of the ball pin and makes the overall processing more convenient.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] (1) By setting up a linkage component, the clamping rod is controlled by the linkage component, so that when the linkage component pushes mold one and mold two to form the ball pin ring groove, it also pushes the clamping rod to assist in clamping the ball pin rod. By cooperating with the clamping component to clamp the ball pin rod, the clamping effect of the ball pin rod is improved, the vibration and displacement of the ball pin head during the processing is reduced, and the processing of the ball pin is facilitated.

[0025] (2) By setting a clamping plate, and the clamping plate is provided with an elastic element that abuts against the ball pin rod, when the processing rod abuts against the ball pin to be processed, the elastic element abuts against the ball pin rod to clamp and fix the ball pin. As the processing rod continues to move, the clamping rod moves together and the moving distance of the clamping rod is less than the moving distance of the processing rod. During this process, the elastic element is squeezed to further clamp the ball pin rod, thereby improving the clamping effect on the ball pin rod.

[0026] (3) By setting a return component, the processing rod is moved back to its original position after forging so that subsequent forging can be carried out. Attached Figure Description

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a ball pin processing device.

[0034] Example:

[0035] See Figure 1 and Figure 2A ball pin processing device includes a machine body 1. The machine body 1 is provided with a driving component 5 and a driving plate 2. The driving component 5 drives the driving plate 2 to move horizontally. A clamping component 4 is provided at the end of the driving plate 2 opposite to the driving component 5. The clamping component 4 is used to clamp the rod part of the ball pin 27. In actual use, the driving component 5 can be a cylinder, or alternatively, a motor, which is threadedly connected to the driving plate 2. The clamping component 4 is a three-jaw chuck. The machine body 1 is provided with a fixed frame 3, a control component 9, and a linkage assembly 10. The fixed frame 3 is located on the side of the clamping component 4 away from the driving plate 2. The fixed frame 3 is provided with a first mold 6 and a second mold 7. The first mold 6 and the second mold 7 are used to form the annular groove of the rod part of the ball pin 27. The first mold 6 and the second mold 7 are both hinged to the fixed frame 3. The hinge axis of the first mold 6 and the fixed frame 3 is parallel to the hinge axis of the second mold 7 and the fixed frame 3. The hinge axis of the first mold 6 and the fixed frame 3 is the sliding direction of the driving plate 2.

[0036] See Figure 2 and Figure 3 The machine body 1 includes a mounting part 8, located on the side of the clamping member 4 away from the drive plate 2. A control member 9 and a linkage assembly 10 are both located on the mounting part 8. There are two mounting parts 8: one located on the side of mold one 6 away from mold two 7, and the other located on the side of mold two 7 away from mold one 6. The control member 9 is connected to the linkage assembly 10, which is connected to a clamping rod 11. The clamping rod 11 is used to clamp the ball pin 27. When the control member 9 drives the linkage assembly 10 to move closer to the ball pin 27, the linkage assembly 10 pushes mold one 6 and mold two 7 to forge the workpiece and pushes the clamping rod 11 to clamp the ball pin 27. In actual use, the control member 9 is a hydraulic cylinder, but it can also be a pneumatic cylinder.

[0037] The linkage assembly 10 includes a first sliding plate 101, a second sliding plate 102, and a fixed plate 103. The first sliding plate 101 is located at the end of the second sliding plate 102 away from the mold 6, and the first sliding plate 101 is connected to the second sliding plate 102. The fixed plate 103 is located on the side of the second sliding plate 102 away from the first sliding plate 101, and a gap is left between the fixed plate 103 and the second sliding plate 102. Both the first sliding plate 101 and the second sliding plate 102 slide on the mounting part 8, and the sliding directions of the first sliding plate 101 and the second sliding plate 102 are the same. The sliding direction of the first sliding plate 101 is either towards or away from the mold 6.

[0038] Sliding plate 101 has a clearance hole 12, and sliding plate 102 has a sliding groove 13. The extension direction of sliding groove 13 is parallel to the sliding direction of drive plate 2. The bottom of sliding groove 13 has a clearance hole 14, which connects to clearance hole 12. Fixed plate 103 has a guide rod 16 that passes through clearance hole 12 and clearance hole 14, extending from the control member 9 towards the clamping member 4. A sliding block 15 slides in sliding groove 13 and along guide rod 16. The sliding direction of sliding block 15 is the extension direction of guide rod 16. When sliding plate 101 and sliding plate 102 move towards mold 6, sliding block 15 slides along the extension direction of guide rod 16.

[0039] The sliding block 15 is provided with an inclined surface 17, which is located on the side of the sliding block 15 away from the sliding plate 101 and on the side of the sliding block 15 away from the guide rod 16. The inclined surface 17 extends in the direction away from the sliding plate 101 toward the direction closer to the guide rod 16.

[0040] The clamping rod 11 is located at the end of the sliding plate 102 away from the sliding plate 101. The clamping rod 11 is provided with a clamping piece 18, which is located at the end of the clamping rod 11 away from the sliding plate 102. The clamping piece 18 is provided with an elastic element 19, which is used to abut against the rod part of the ball pin 27. In actual use, the elastic element 19 can be made of rubber, or alternatively, it can be made of silicone.

[0041] The fixed plate 103 is provided with a processing rod 20, which slides on the fixed plate 103. The sliding direction of the processing rod 20 is the same as that of the sliding plate 101. The processing rod 20 is used to push the mold 6 to rotate and abut against the ball pin 27 to be processed. The processing rod 20 includes a rod body 201, abutting block 202, and a processing plate. The processing plate is located at the end of the rod body 201 away from the sliding plate 101, and is used to abut against the ball pin 27 to be processed. The abutting block 202 is located at the end of the rod body 201 away from the mold 6. The abutting block 202 is provided with an inclined surface 21, which is located at the end of the abutting block 202 close to the sliding plate 101. The inclined surface 21 is parallel to the inclined surface 17 and is used to abut against the inclined surface 17.

[0042] When the control component 9 pushes the sliding plate 101 to move, the sliding plate 101 drives the sliding plate 2 102 to move towards the mold 6. The movement of the sliding plate 2 102 causes the sliding block 15 to move along the inclined direction of the guide rod 16 and cause the inclined surface to abut against the processing rod 20 and push the processing rod 20. The moving distance of the processing rod 20 is greater than the moving distance of the clamping rod 11. When the processing rod 20 abuts against the ball pin 27 to be processed, the elastic element 19 of the clamping rod 11 abuts against the ball pin 27 rod and clamps the ball pin 27 rod.

[0043] See Figure 3 and Figure 4 The processing rod 20 is equipped with a return element for restoring its position. Inclined surface 17 has a limiting groove 22, and the groove wall of the limiting groove 22 has a fixing groove 23. Inclined surface 21 has a limiting protrusion 24, which is embedded in the limiting groove 22. The return element includes a fixing protrusion 25 located on the side wall of the limiting protrusion 24. The fixing protrusion 25 is embedded in the fixing groove 23 to restrict the limiting protrusion 24 from disengaging from the limiting groove 22 in a direction perpendicular to the inclined surface 17. Alternatively, the return element may also include a limiting spring 26, the elastic force of which restricts the movement of the processing rod 20 toward the mold 6.

[0044] In actual use, the machine body 1 is equipped with a heating component, which is located between the mounting part 8 and the clamping part 4. The heating component is used to heat the part of the ball pin 27 to be processed.

[0045] The working principle of this embodiment is as follows:

[0046] When the control unit 9 pushes the sliding plate 101 to move, the sliding plate 101 drives the sliding plate 102 to move closer to the mold 6. The movement of the sliding plate 102 causes the sliding block 15 to move along the inclined direction of the guide rod 16, so that the inclined surface abuts against the processing rod 20 and pushes the processing rod 20. As the sliding block 15 moves, the abutting block 202 changes from abutting against the inclined surface 17 to abutting against the end of the sliding block 15 away from the sliding plate 101. Therefore, the moving distance of the processing rod 20 is greater than the moving distance of the clamping rod 11.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
