Description

Technical Field

[0001] This utility model belongs to the technical field of pin shaft processing equipment and relates to pin shaft processing tooling. Background Technology

[0002] During the machining of pins, depending on the installation position and usage method, holes or slots need to be drilled at both ends of the pin. To ensure machining at the designated position, multiple processes such as alignment, scribing, and center punching are required for each pin before clamping it onto a drilling machine for drilling and slotting. However, when it is necessary to create mutually perpendicular slots or holes at both ends of the pin, a secondary clamping is required. The secondary clamping has a different reference point than the first clamping, making it difficult to guarantee the perpendicularity between the two holes, thus affecting the machining quality. Utility Model Content

[0003] The purpose of this invention is to provide a tooling for machining pins, which solves the problem in the prior art that when drilling pins, re-clamping is required to adjust the rotation angle, making it difficult to guarantee machining accuracy.

[0004] The technical solution adopted by this utility model includes a square work platform. Parallel positioning plates are fixedly connected to the top surface of the work platform. V-shaped grooves with upward openings are opened on the positioning plates. Limiting posts are fixedly connected to the four corners of the top surface of the work platform. A fixing plate parallel to the positioning plates is set between the two limiting posts. An adjustment groove is opened between the two positioning plates on the top surface of the work platform. An adjustment roller is rotatably connected in the adjustment groove, and the axis of the adjustment roller is perpendicular to the positioning plates. An adjustment component is fixedly connected to the adjustment roller through a rotating shaft. A drive component is set on one side of the adjustment component. An adjustment knob is fixedly connected to the drive component, and the adjustment knob is located on the surface of the work platform. Both the adjustment component and the drive component are located inside the work platform.

[0005] The features of this utility model also include:

[0006] The outer wall of the top of the limiting post is threaded, the fixing plate is sleeved on the two limiting posts, and the limiting post is equipped with a locking nut above the fixing plate.

[0007] The outer wall of the adjusting roller extends out from the adjusting groove, and the highest point of the outer wall of the adjusting roller is higher than the lowest point of the V-shaped groove on the positioning plate.

[0008] The adjustment assembly includes a transmission cone block located inside the working platform and fixedly connected to the shaft of the adjustment roller. A coaxial adjustment cone block is provided on the side of the transmission cone block away from the adjustment roller. A threaded rod is fixedly connected to the side of the adjustment cone block away from the transmission cone block. An adjustment sleeve is provided on the side wall of the working platform. The adjustment sleeve extends into the working platform and is threadedly connected to the threaded rod. The diameter of the side of the adjustment cone block and the transmission cone block opposite each other is smaller than the side of the adjustment cone block and the transmission cone block opposite to each other. A transmission belt is sleeved between the adjustment cone block and the transmission cone block.

[0009] The drive assembly includes a pulley fitted inside a transmission belt, a first bevel gear fixedly connected to the pulley, the first bevel gear meshing with a second bevel gear, and the second bevel gear fixedly connected to an adjustment knob via a shaft.

[0010] The surface of the adjusting roller is covered with a rubber layer.

[0011] The inclined surface of the transmission cone is covered with rubber, while the inclined surface of the adjusting cone is made of metal.

[0012] The width of the drive belt is greater than the furthest distance between the adjusting cone and the drive cone.

[0013] The diameter of the wheel gradually decreases from both ends to the middle.

[0014] Beneficial effects:

[0015] This invention uses an adjusting component and a driving component to drive an adjusting roller to rotate, which in turn drives a pin to rotate, adjusting the angle between the pin and the processing equipment to allow for drilling at different angles on the pin without reclamping it. Simultaneously, within the adjusting component, an adjusting sleeve changes the distance between the adjusting cone and the transmission cone, altering the rotation radius of the transmission belt within one end of the adjusting component and changing the transmission ratio. When dealing with pins of different diameters, adjusting the transmission ratio ensures that the rotation angle of the adjusting knob matches the rotation angle of the pin, reducing adjustment errors.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Example 1:

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the work platform includes a square work platform 1. Parallel positioning plates 2 are fixedly connected to the top surface of the work platform 1. V-shaped grooves 3 with upward openings are opened on the positioning plates 2. Limiting posts 4 are fixedly connected to the four corners of the top surface of the work platform 1. A fixing plate 5 parallel to the positioning plate 2 is set between the two limiting posts 4. An adjustment groove 6 is opened between the two positioning plates 2 on the top surface of the work platform 1. An adjustment roller 7 is rotatably connected in the adjustment groove 6. The axis of the adjustment roller 7 is perpendicular to the positioning plate 2. An adjustment component 8 is fixedly connected to the adjustment roller 7 through a rotating shaft. A drive component 9 is set on one side of the adjustment component 8. An adjustment knob 19 is fixedly connected to the drive component 9. The adjustment knob 19 is located on the surface of the work platform 1. The adjustment component 8 and the drive component 9 are both located inside the work platform 1.

[0025] During the pin machining process, the pin to be machined is first placed into the V-groove 3 of the two positioning plates 2. Then, the positioning plates 2 press the pin downward to fix it on the tooling and make the side wall of the pin abut against the adjusting roller 7. At this time, the pin can be drilled.

[0026] When it is necessary to change the drilling angle, the adjusting roller 7 can be rotated by the drive assembly 9 and the adjusting assembly 8. The friction between the side wall of the adjusting roller 7 and the pin shaft drives the pin shaft to rotate in the V-groove 3, thereby adjusting the relative position between the pin shaft and the drilling equipment without having to remove the pin shaft from the tooling and re-fix it.

[0027] Example 2:

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the work platform includes a square work platform 1. Parallel positioning plates 2 are fixedly connected to the top surface of the work platform 1. V-shaped grooves 3 with upward openings are opened on the positioning plates 2. Limiting posts 4 are fixedly connected to the four corners of the top surface of the work platform 1. A fixing plate 5 parallel to the positioning plate 2 is set between the two limiting posts 4. An adjustment groove 6 is opened between the two positioning plates 2 on the top surface of the work platform 1. An adjustment roller 7 is rotatably connected in the adjustment groove 6. The axis of the adjustment roller 7 is perpendicular to the positioning plate 2. An adjustment component 8 is fixedly connected to the adjustment roller 7 through a rotating shaft. A drive component 9 is set on one side of the adjustment component 8. An adjustment knob 19 is fixedly connected to the drive component 9. The adjustment knob 19 is located on the surface of the work platform 1. The adjustment component 8 and the drive component 9 are both located inside the work platform 1.

[0029] The top outer wall of the limiting post 4 is threaded, the fixing plate 5 is sleeved on the two limiting posts 4, and the limiting post 4 is provided with a locking nut 10 above the fixing plate 5.

[0030] The outer wall of the adjusting roller 7 extends out from the adjusting groove 6, and the highest point of the outer wall of the adjusting roller 7 is higher than the lowest point of the V-shaped groove 3 on the positioning plate 2.

[0031] By applying a clamping force to the fixing plate 5 with the locking nut 10, the pin to be processed can be stably fixed in the V-groove, avoiding the influence of external forces applied by the processing equipment during the processing of the pin, thus preventing slight displacement that could affect the processing accuracy.

[0032] The fact that the highest point of the outer wall of the adjusting roller 7 is higher than the lowest point of the V-groove 3 on the positioning plate 2 ensures that the adjusting roller 7 is in contact with the pin to be processed, thereby driving the pin to rotate through the adjusting roller 7 and realizing the adjustment of the relative position between the pin and the processing equipment.

[0033] Example 3:

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the work platform includes a square work platform 1. Parallel positioning plates 2 are fixedly connected to the top surface of the work platform 1. V-shaped grooves 3 with upward openings are opened on the positioning plates 2. Limiting posts 4 are fixedly connected to the four corners of the top surface of the work platform 1. A fixing plate 5 parallel to the positioning plate 2 is set between the two limiting posts 4. An adjustment groove 6 is opened between the two positioning plates 2 on the top surface of the work platform 1. An adjustment roller 7 is rotatably connected in the adjustment groove 6. The axis of the adjustment roller 7 is perpendicular to the positioning plate 2. An adjustment component 8 is fixedly connected to the adjustment roller 7 through a rotating shaft. A drive component 9 is set on one side of the adjustment component 8. An adjustment knob 19 is fixedly connected to the drive component 9. The adjustment knob 19 is located on the surface of the work platform 1. The adjustment component 8 and the drive component 9 are both located inside the work platform 1.

[0035] like Figure 4 As shown, the adjustment assembly 8 includes a transmission cone 11 located inside the working platform 1 and fixedly connected to the rotating shaft of the adjustment roller 7. A coaxial adjustment cone 12 is provided on the side of the transmission cone 11 away from the adjustment roller 7. A threaded rod 13 is fixedly connected to the side of the adjustment cone 12 away from the transmission cone 11. An adjustment sleeve 14 is provided on the side wall of the working platform 1. The adjustment sleeve 14 extends into the working platform 1 and is threadedly connected to the threaded rod 13. The diameter of the side opposite to the adjustment cone 12 and the transmission cone 11 is smaller than the side opposite to the adjustment cone 12 and the transmission cone 11. A transmission belt 15 is sleeved between the adjustment cone 12 and the transmission cone 11.

[0036] Since the adjusting sleeve 14 is threadedly connected to the threaded rod 13, and the threaded rod 13 is fixedly connected to the adjusting cone 12, the adjusting cone 12 moves horizontally along the axial direction as the threaded rod 13 rotates in or out of the adjusting sleeve 14. When the adjusting cone 12 moves away from the transmission cone 11, the transmission belt 15 moves between the two cones; when the adjusting cone 12 moves closer to the transmission cone 11, the transmission belt 15 moves towards the edge of the two cones under compression. By adjusting the translation of the adjusting cone 12, the rotation radius of the transmission belt 15 between the two cones can be changed, thereby adjusting the transmission ratio. The transmission ratio can be adjusted according to the different diameters of the pins to be processed, so as to achieve synchronous rotation of the drive assembly 9 and the pin.

[0037] Example 4:

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the work platform includes a square work platform 1. Parallel positioning plates 2 are fixedly connected to the top surface of the work platform 1. V-shaped grooves 3 with upward openings are opened on the positioning plates 2. Limiting posts 4 are fixedly connected to the four corners of the top surface of the work platform 1. A fixing plate 5 parallel to the positioning plate 2 is set between the two limiting posts 4. An adjustment groove 6 is opened between the two positioning plates 2 on the top surface of the work platform 1. An adjustment roller 7 is rotatably connected in the adjustment groove 6. The axis of the adjustment roller 7 is perpendicular to the positioning plate 2. An adjustment component 8 is fixedly connected to the adjustment roller 7 through a rotating shaft. A drive component 9 is set on one side of the adjustment component 8. An adjustment knob 19 is fixedly connected to the drive component 9. The adjustment knob 19 is located on the surface of the work platform 1. The adjustment component 8 and the drive component 9 are both located inside the work platform 1.

[0039] like Figure 4 As shown, the adjustment assembly 8 includes a transmission cone 11 located inside the working platform 1 and fixedly connected to the rotating shaft of the adjustment roller 7. A coaxial adjustment cone 12 is provided on the side of the transmission cone 11 away from the adjustment roller 7. A threaded rod 13 is fixedly connected to the side of the adjustment cone 12 away from the transmission cone 11. An adjustment sleeve 14 is provided on the side wall of the working platform 1. The adjustment sleeve 14 extends into the working platform 1 and is threadedly connected to the threaded rod 13. The diameter of the side opposite to the adjustment cone 12 and the transmission cone 11 is smaller than the side opposite to the adjustment cone 12 and the transmission cone 11. A transmission belt 15 is sleeved between the adjustment cone 12 and the transmission cone 11.

[0040] like Figure 1 and Figure 5 As shown, the drive assembly 9 includes a pulley 16 sleeved in the transmission belt 15, a first bevel gear 17 coaxially connected to the pulley 16, the first bevel gear 17 meshing with a second bevel gear 18, and the second bevel gear 18 being fixedly connected to the adjustment knob 19 via a rotating shaft.

[0041] The rotation direction of the transmission belt is changed by the cooperation of the first bevel gear 17 and the second bevel gear 18, which shortens the transmission distance. At the same time, the adjustment knob 19 connected to the second bevel gear 18 drives the rotating wheel 16 to rotate, thereby driving the adjustment roller 7 to rotate through the transmission belt 15, so as to realize the angle adjustment of the pin shaft.

[0042] Example 5:

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, the work platform includes a square work platform 1. Parallel positioning plates 2 are fixedly connected to the top surface of the work platform 1. V-shaped grooves 3 with upward openings are opened on the positioning plates 2. Limiting posts 4 are fixedly connected to the four corners of the top surface of the work platform 1. A fixing plate 5 parallel to the positioning plate 2 is set between the two limiting posts 4. An adjustment groove 6 is opened between the two positioning plates 2 on the top surface of the work platform 1. An adjustment roller 7 is rotatably connected in the adjustment groove 6. The axis of the adjustment roller 7 is perpendicular to the positioning plate 2. An adjustment component 8 is fixedly connected to the adjustment roller 7 through a rotating shaft. A drive component 9 is set on one side of the adjustment component 8. An adjustment knob 19 is fixedly connected to the drive component 9. The adjustment knob 19 is located on the surface of the work platform 1. The adjustment component 8 and the drive component 9 are both located inside the work platform 1.

[0044] like Figure 4 As shown, the adjustment assembly 8 includes a transmission cone 11 located inside the working platform 1 and fixedly connected to the rotating shaft of the adjustment roller 7. A coaxial adjustment cone 12 is provided on the side of the transmission cone 11 away from the adjustment roller 7. A threaded rod 13 is fixedly connected to the side of the adjustment cone 12 away from the transmission cone 11. An adjustment sleeve 14 is provided on the side wall of the working platform 1. The adjustment sleeve 14 extends into the working platform 1 and is threadedly connected to the threaded rod 13. The diameter of the side opposite to the adjustment cone 12 and the transmission cone 11 is smaller than the side opposite to the adjustment cone 12 and the transmission cone 11. A transmission belt 15 is sleeved between the adjustment cone 12 and the transmission cone 11.

[0045] The surface of the adjusting roller 7 is covered with a rubber layer.

[0046] The inclined surface of the transmission cone 11 is covered with rubber, while the inclined surface of the adjusting cone 12 is made of metal.

[0047] The rubber layer on the surface of the adjusting roller 7 can increase the friction between it and the pin, so that the adjusting roller 7 can rotate stably relative to the pin.

[0048] During the tooling adjustment process, the function of the adjusting cone 12 is to adjust the rotation radius by squeezing the transmission belt 15. The adjusting cone 12 itself does not participate in the transmission, therefore the inclined surface of the adjusting cone 12 is made of metal, which promotes the displacement of the transmission belt 15 by reducing friction. The function of the transmission cone 11 is to transmit the power of the drive assembly 9 to the adjusting roller 7. Therefore, a rubber layer is used on the surface of the transmission cone 11 to increase friction and enable it to transmit power stably.

[0049] Example 6:

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, the work platform includes a square work platform 1. Parallel positioning plates 2 are fixedly connected to the top surface of the work platform 1. V-shaped grooves 3 with upward openings are opened on the positioning plates 2. Limiting posts 4 are fixedly connected to the four corners of the top surface of the work platform 1. A fixing plate 5 parallel to the positioning plate 2 is set between the two limiting posts 4. An adjustment groove 6 is opened between the two positioning plates 2 on the top surface of the work platform 1. An adjustment roller 7 is rotatably connected in the adjustment groove 6. The axis of the adjustment roller 7 is perpendicular to the positioning plate 2. An adjustment component 8 is fixedly connected to the adjustment roller 7 through a rotating shaft. A drive component 9 is set on one side of the adjustment component 8. An adjustment knob 19 is fixedly connected to the drive component 9. The adjustment knob 19 is located on the surface of the work platform 1. The adjustment component 8 and the drive component 9 are both located inside the work platform 1.

[0051] like Figure 4 As shown, the adjustment assembly 8 includes a transmission cone 11 located inside the working platform 1 and fixedly connected to the rotating shaft of the adjustment roller 7. A coaxial adjustment cone 12 is provided on the side of the transmission cone 11 away from the adjustment roller 7. A threaded rod 13 is fixedly connected to the side of the adjustment cone 12 away from the transmission cone 11. An adjustment sleeve 14 is provided on the side wall of the working platform 1. The adjustment sleeve 14 extends into the working platform 1 and is threadedly connected to the threaded rod 13. The diameter of the side opposite to the adjustment cone 12 and the transmission cone 11 is smaller than the side opposite to the adjustment cone 12 and the transmission cone 11. A transmission belt 15 is sleeved between the adjustment cone 12 and the transmission cone 11.

[0052] like Figure 5 As shown, the drive assembly 9 includes a pulley 16 sleeved in the transmission belt 15, a first bevel gear 17 coaxially connected to the pulley 16, the first bevel gear 17 meshing with a second bevel gear 18, and the second bevel gear 18 being fixedly connected to the adjustment knob 19 via a rotating shaft.

[0053] The width of the drive belt 15 is greater than the farthest distance between the adjusting cone 12 and the drive cone 11.

[0054] The diameter of the rotor 16 gradually decreases from both ends to the middle.

[0055] The fact that the pulley 16 is thicker at both ends and thinner in the middle can keep the transmission belt 15 stable in the middle section of the pulley 16, avoiding changes in the transmission ratio caused by the deviation of the transmission belt 15 during transmission, and making the rotation of the pin more stable.

[0056] This invention uses an adjusting component and a driving component to drive an adjusting roller to rotate, which in turn drives a pin to rotate, adjusting the angle between the pin and the processing equipment to perform drilling at different angles on the pin. Simultaneously, the adjusting cone 12 and the transmission cone 11 form a rotating shaft. Due to the inclined plane between the two cones, the actual radius of the rotating shaft increases when the two cones are close together and decreases when they are far apart. By changing the radius, the transmission ratio can be adjusted, ensuring that the rotation angle of the adjusting knob 19 is the same as the rotation angle of the pin, thus improving adjustment accuracy and reducing adjustment errors.

[0057] Working principle:

[0058] When machining the pin, first place the pin to be machined into the V-groove 3 of the positioning plate 2, then attach the fixing plate 5 onto the limiting post 4 and use the locking nut 10 to fix the fixing plate 5 onto the limiting post. At this time, the pin can be machined.

[0059] After the pin is machined, rotate the adjusting sleeve 14 to adjust the distance between the transmission cone 11 and the adjusting cone 12 so that the rotation angle when rotating the adjusting knob 19 is the same as the rotation angle of the pin.

[0060] After adjustment, rotate the adjustment knob 19. The pin will rotate via the transmission belt 15 and the adjustment roller 7. The rotation will stop when the pin reaches the specified angle. At this point, the pin can be further processed.
