[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] The utility model, when the chamber and the spring are used in conjunction with the T-block and the locating pin, the locating pin is rotated, and because the first thread and the second thread are in a biting state, the locating pin can be rotated and moved downward, and when the T-block is squeezed by the locating pin during movement, the T-block will move to both sides for squeezing, and the arc block will come into contact with the inner wall of the mounting hole during the movement and the mounting seat can be fixed on the assembly base through the above operation, and vice versa, the mounting seat can be taken out from the assembly base, thereby realizing the process of rapid installation and disassembly of the positioning fixture, greatly improving the convenience of operation.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] Example:

[0018] As attached Figure 1 To Attachment Figure 3 As shown:

[0019] The utility model provides an automobile spare parts positioning fixture, comprising a mounting seat 2, a positioning fixture 3 is installed on the top of the mounting seat 2, a plurality of mounting holes are penetrated through the surface of the mounting seat 2, and the mounting seat 2 is assembled on an assembly base 1 through a positioning pin assembly and the mounting holes.

[0020] Wherein, the positioning pin assembly includes a sleeve seat 4, a through hole groove is penetrated through the top of the sleeve seat 4, and a thread 6 is provided on the inner wall of the through hole groove.

[0021] The sleeve seat 4 is provided with a positioning pin 5 through a through hole groove, and the outer wall of the positioning pin 5 is provided with a second thread 7, and the second thread 7 and the first thread 6 are engaged with each other.

[0022] Among them, the outer wall of the sleeve seat 4 is symmetrically penetrated by a chamber 12, the inner wall of the chamber 12 is provided with a limit groove, a T-block 8 is slidably provided between the limit grooves, and a spring 11 is installed on the T-block 8 in the chamber 12. When the chamber 12 and the spring 11 are used in conjunction with the T-block 8 and the positioning pin 5, the positioning pin 5 is rotated. Since the thread 1 6 and the thread 2 7 are in a bite state, the positioning pin 5 can be rotated and moved downward. When the T-block 8 is squeezed by the positioning pin 5 during movement, the T-block 8 will move and squeeze to both sides, and when moving and squeezing, the arc block 10 will contact the inner wall of the mounting hole. Through the above operation, the mounting seat 2 can be fixed on the assembly base 1, and vice versa, the mounting seat 2 can be taken out from the assembly base 1.

[0023] Among them, an arc block 10 is installed on one side of the T-block 8, and an arc block 2 9 is installed on the other side of the T-block 8, and the distance between an adjacent pair of arc blocks 2 9 is smaller than the diameter of the positioning pin 5.

[0024] The specific usage and function of this embodiment are as follows:

[0025] First, install the assembly base 1 on the processing equipment, and then install the positioning fixture on the surface of the mounting base 2. Hold the mounting base 2 and align the mounting hole on its surface with the positioning pin assembly for insertion. After insertion, rotate the positioning pin 5 by means of a handle or other tool. Since the thread 2 7 on the surface of the positioning pin 5 is in a bite state with the thread 1 6 in the through hole groove, the positioning pin 5 can be rotated and moved downward. When the T-block 8 receives the positioning pin 5 for extrusion during movement, the T-block 8 will move and extrude to both sides, and the arc block 10 will contact the inner wall of the mounting hole during movement and extrusion. The mounting base 2 can be fixed on the assembly base 1 through the above operation, and vice versa, the mounting base 2 can be removed from the assembly base 1. The above operation can realize the rapid installation and disassembly of the positioning fixture, which can be distinguished from the traditional bolt fixing method and greatly improves the convenience of the overall operation. Therefore, it is worthy of wide promotion and use.

[0026] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
