AI Technical Summary
During the process of machining the thrust rod seat on a car, the two adjacent sides are angled, which causes the workpiece to be removed, adjusted and re-clamped after processing one surface and then processed the other surface, which is time-consuming and labor-intensive, and is easy to cause reference errors and reduce processing accuracy.
A rotatable clamping platform is designed, with the rotation angle of the platform equal to the angle between the two sides that the workpiece needs to be processed, so that the second side is quickly positioned and processed without re-clamping. The platform achieves fast and accurate angle positioning through the cooperation of arc-shaped grooves, limiting pins and positioning holes.
Through this design, the step of re-cluttering when processing the second side of the workpiece is eliminated, the processing efficiency and accuracy are improved, and the reference error caused by re-cluttering is reduced.

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.
[0016] like Figures 1-2 As shown, a machining device for an upper thrust rod seat of the present embodiment comprises a base 1 fixed to a workbench, the top of the base 1 is rotatably connected to a bottom plate 4 via a pin shaft 2, the bottom plate 4 is provided with an arc groove 5, the base 1 is provided with a limit pin 6 slidably connected to the arc groove 5, the base 1 and the bottom plate 4 are provided with positioning holes passing through the two, the positioning holes are inserted with positioning pins 7; two adjacent sides of the bottom plate 4 have equal angles with two surfaces of the workpiece to be processed, two positioning blocks 8 for constraining the workpiece are respectively provided on the bottom plate 4 near the two sides, and the bottom plate 4 is also provided with two clamping devices 9 for clamping the workpiece.
[0017] The present embodiment is specially used for the milling and drilling of two adjacent side surfaces of the upper thrust rod seat. In order to save the need for re-clamping when processing the second side surface, the present embodiment clamps the workpiece on a rotatable fixture, wherein when positioning and clamping the workpiece, the positioning block 8 is first used for positioning, and then the clamping device 9 is used for clamping and fixing; the rotatable fixture realizes the rotation of the entire fixture by the rotation of the base plate 4 relative to the base 1, wherein the base plate 4 rotates around the pin shaft 2 fixed to the base 1, and the rotation angle is limited by the cooperation of the arc groove 5 and the limit pin 6, so that each rotation can be completed quickly and accurately. After the rotation is completed, the positioning pin 7 is inserted into the hole passing through the base plate 4 and the base 1, so as to position and fix the base plate 4; then the locking nut 3 is screwed on the top of the pin shaft 2 to clamp the base plate 4 to prevent it from moving.
[0018] In addition, the clamping device 9 includes a support column 91, a screw rod 92 and a pressure plate 93 fixed to the bottom plate 4. The pressure plate 93 is sleeved on the screw rod 92 and locked by a nut. The two ends of the pressure plate 93 are pressed on the support column 91 and the workpiece respectively. A round pin with a smaller diameter can also be provided on the top of the support column 91 to be sleeved with the pressure plate 4, so that when the nut on the screw rod 92 is loosened, the pressure plate 93 will not fall off, which is convenient for quick clamping when used next time.
[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, and for the convenience of describing the technical solution, the front, rear, left, right, top, middle, and bottom directions adopted are based on the settings in the accompanying drawings, rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
