[0039] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0040] like Figures 1-2 The accompanying drawing shows a schematic diagram of the structure of a clamping device for processing shift forks according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0041] In this embodiment, a clamping device for processing shift forks is provided, including a base 1, a first pressure plate 2, a second pressure plate 3, a third pressure plate 4, a fourth pressure plate 5, a locking block 6, a first positioning post 7, a second positioning post 8, a positioning block 9, a driving component 10, and a shift fork product 11.

[0042] In this embodiment, the top of the base 1 is provided with a clamping area for clamping the shift fork product 11. The bottom of the base 1 is provided with multiple mounting holes (not shown in the figure) for fixing the device to the processing equipment or workbench; a shock-absorbing pad (not shown in the figure) is added under the base 1 to reduce vibration interference during processing.

[0043] In this embodiment, the first pressure plate 2 and the second pressure plate 3 are symmetrically distributed on the same side of the clamping area. The drive member 10 controls their movement in the vertical direction to clamp the workpiece from the thickness direction (i.e., the vertical direction) of the shift fork product 11.

[0044] In this embodiment, the third pressure plate 4 is disposed on the other side of the clamping area, staggered from the first pressure plate 2 and the second pressure plate 3, to ensure uniform distribution of clamping force. The third pressure plate 4 is also driven by the drive member 10, applying clamping force to the shift fork product 11 in the vertical direction.

[0045] In this embodiment, the fourth pressure plate 5 includes a fourth pressure plate drive component 501, a drive output end 502, and a pressure head 503. The fourth pressure plate drive component 501 (in this embodiment, a cylinder) is fixed on the base 1. The drive output end 502 moves linearly along a direction perpendicular to the opening of the engagement groove 602, driving the pressure head 503 to move towards the engagement groove 602. The contact surface of the pressure head 503 is covered with an elastic buffer layer (such as rubber or polyurethane) to prevent damage to the surface of the shift fork product 11 during pressing.

[0046] In this embodiment, the first positioning post 7 and the second positioning post 8 are vertically fixed at the bottom of the clamping area of ​​the base 1, and cooperate with the hole or groove at the bottom of the shift fork product 11 to achieve initial positioning.

[0047] In this embodiment, the positioning block 9 is fixed on the base 1, and its top positioning surface is a high-precision plane, which serves as the reference surface of the shift fork product 11 to ensure the levelness of the workpiece during processing.

[0048] In this embodiment, the locking block 6 is fixed to the base 1 by bolts, and its locking body 601 is a high-strength steel structure. A locking groove 602 with a "V" shaped cross section is opened on one side of the locking body 601, which matches the shape of the corresponding part of the shift fork product 11 to ensure that the workpiece does not wobble after being locked in; the inclined sidewall of the locking groove 602 can adapt to shift fork products 11 of different sizes, enhancing versatility.

[0049] In this embodiment, the drive unit 10 adopts a pneumatic drive device (which can also be replaced by a hydraulic or electric drive device). The linkage mechanism synchronously controls the movements of the first pressure plate 2, the second pressure plate 3, the third pressure plate 4, and the fourth pressure plate 5 to ensure that the clamping actions are coordinated and consistent. The output end of the drive unit 10 is connected to each pressure plate, and the clamping and releasing are quickly switched through program or manual control.

[0050] In practical application, the working method of this utility model is as follows:

[0051] Workpiece placement: Place the bottom of the shift fork product 11 against the flat positioning surface of the positioning block 9, and insert the first positioning post 7 and the second positioning post 8 into the corresponding holes on the bottom of the workpiece to complete the initial positioning;

[0052] Engaging and fixing: The fork arm of the shift fork product 11 is embedded into the "V" shaped engagement groove 602 of the engagement block 6, and the workpiece is self-clamped by the inclined surface of the engagement groove 602.

[0053] Clamping of pressure plates: The drive unit 10 is activated, driving the first pressure plate 2, the second pressure plate 3 and the third pressure plate 4 to simultaneously press the thickness sides of the shift fork product 11 in the vertical direction; the fourth pressure plate drive unit 501 pushes the drive output end 502, causing the pressure head 503 to move in a straight line, pressing the shift fork product 11 from the side away from the locking groove 602, forming opposing clamping;

[0054] After processing, the drive unit 10 reverses its movement, and all pressure plates and the fourth pressure plate 5 are reset, allowing the shift fork product 11 to be easily removed.

[0055] This utility model has a reasonable structure and is easy to operate. By cooperating with the multi-directional pressure plate and the "V"-shaped locking groove 602, it solves the problem of workpiece deformation caused by uneven or excessive clamping force in traditional fixtures. In addition, the combination of the first positioning post 7, the second positioning post 8 and the positioning block 9 achieves high-precision positioning, further ensuring the quality of the machined surface.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
