The processing of automotive parts is demanding, and because most parts have irregular structures, clamping difficulties are common during manufacturing. In CNC machining, issues such as difficulty in ensuring dimensions, positioning, and low processing efficiency are prevalent. Therefore, there is an urgent need for a new type of inspection fixture to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a fixture for processing automotive parts, so as to solve the existing technical problems of difficult processing and positioning of irregular products.

[0004] This utility model discloses a fixture for processing automotive parts, comprising a base, wherein the base includes a side plate and a bottom plate, the bottom plate is provided with a groove for placing a workpiece, a limiting post is fixedly installed on the side plate, a screw hole is provided at the center of the limiting post, a screw is screwed into the screw hole, and the front end of the limiting post is provided with multiple slots arranged in a ring array.

[0005] Preferably, the base has an overall L-shaped structure, the side plate is provided with a mounting groove, one end of the limiting post is installed in the mounting groove and fixed by screws.

[0006] Preferably, a circular turntable is provided on the outer side of the side plate, and the circular turntable is provided with multiple mounting holes. The circular turntable is fixed on a four-axis machine and drives the workpiece on the base to rotate.

[0007] Preferably, one end of the workpiece is clamped in the groove, and the other end is fixed to the base by a limiting post.

[0008] Preferably, the base plate is arranged parallel to the workpiece.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This type of fixture for processing automotive parts mainly includes a base on which the workpiece is fixed. The base includes a side plate and a bottom plate. The side plate is vertically mounted on one side of the bottom plate. The bottom plate has a groove, and the side plate has a limiting post. One end of the workpiece is placed in the groove, and the other end is installed in the limiting post by a screw. Because the front end of the limiting post has multiple gaps, when the screw passes through the screw hole at the front end and is tightened inward, the front end of the limiting post will be pushed outward under the pressure of the screw, that is, pushed towards the inner wall of the workpiece, so that the limiting post abuts against the inner wall of the workpiece. Thus, one end of the workpiece will be fixed to the limiting post, achieving the effect of fixing the workpiece, ensuring the positioning effect of the fixture, and improving processing efficiency.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] like Figure 1-2 As shown, the present invention discloses a fixture for processing automotive parts, including a base 1, the base including a side plate 11 and a bottom plate 12, the bottom plate 12 having a groove 121 for placing a workpiece 2, a limiting post 111 fixedly installed on the side plate 11, a screw hole 112 at the center of the limiting post 111, a screw 113 screwed into the screw hole 112, and a plurality of slots 114 arranged in a ring array at the front end of the limiting post 111.

[0017] This utility model discloses a fixture for processing automotive parts, comprising a base 1, on which a workpiece 2 is fixed. The base 1 includes a side plate 11 and a bottom plate 12. The side plate 11 is vertically mounted on one side of the bottom plate 12. The bottom plate 12 has a groove 121, and the side plate 11 has a limiting post 111. One end of the workpiece is placed in the groove 121, and the other end is installed in the limiting post 111 by a screw 113. Since the front end of the limiting post 111 has multiple slits 114, when the screw 113 passes through the screw hole 112 at the front end and is tightened inward, the front end of the limiting post 111 will be pushed outward under the pressure of the screw 113, that is, pushed towards the inner wall of the workpiece, so that the limiting post 111 abuts against the inner wall of the workpiece 2, and one end of the workpiece 2 will be fixed to the limiting post, thus achieving the effect of fixing the workpiece.

[0018] In a preferred embodiment, refer to Figure 1 and 2 The base 1 of the fixture for processing automotive parts has an overall L-shaped structure. A mounting groove 115 is provided on the side plate 11. One end of a limiting post 111 is installed in the mounting groove 115 and fixed with screws. A circular turntable 3 is provided on the outer side of the side plate 11. The circular turntable 3 has multiple mounting holes 31. The circular turntable 3 is fixed to a four-axis machine and drives the workpiece 2 on the base 1 to rotate. One end of the workpiece 2 is clamped in a groove 121, and the other end is fixed to the base 1 by the limiting post 111. The base plate 12 is arranged parallel to the workpiece 2.

[0019] Specifically, the mounting slot 115 is provided with a first screw hole at its center, and the circular turntable 3 is also provided with a second screw hole concentric with the first screw hole at its center. When fixing the limiting post 111, the screw passes through the outside of the second screw hole through the circular turntable 3 to the inside of the limiting post 111, so that the limiting post 111 is fixedly installed on the side plate 11, ensuring the stability of the limiting post 111. The four-axis machine adds a rotary axis to the three-axis (X, Y, Z axis) machining. The base 1 is installed on the four-axis machine through the circular turntable 31, so that the circular turntable 31 can also drive the workpiece 2 to move in four axes, ensuring the convenience and efficiency of machining the workpiece. By setting the workpiece 2 parallel to the base plate 12, the stability of the workpiece 2 installation is ensured, and it is ensured that it will not loosen during the machining process, thus affecting the forming of the finished product.

[0020] In the specific installation of this fixture for processing automotive parts, the limiting post 111 is first inserted into the mounting groove 115. Then, screws are passed through the circular turntable 3 to the inside of the limiting post 111 inside the mounting groove 115, fixing the circular turntable 3, side plate 11, and limiting post 111. Next, the bottom of the workpiece 2 is pushed from the groove 121 of the base plate 12 to the position of the limiting post 111, so that one end of the workpiece 2 is fitted onto the outside of the limiting post 111. Finally, screws 113 are passed through the screw hole 112 at the front end of the limiting post 111, causing the front end of the limiting post 111 to open outward, while fixing the workpiece. Finally, the entire structure is fixed on the four-axis machine.

[0021] This fixture for machining automotive parts also has the following characteristics:

[0022] The clamping mechanism of this application achieves rapid product clamping, further improving clamping efficiency; the limiting post and groove 121 prevent clamping deviation, further improving clamping accuracy; and the screw and screw positioning fixture achieve rapid clamping, further ensuring clamping reliability and stability.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
