[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a special inspection tool for a speed sensor protective cover.

[0027] This utility model provides, for example Figs. 1-6 The speed sensor protective cover fixture shown includes a base plate 1. The surface of the base plate 1 is provided with a first positioning block 2, a second positioning block 3, a third positioning block 4, and a fourth positioning block 5, as well as a support block 6. The support block 6 is located between the first positioning block 2 and the second positioning block 3. The tops of the second positioning block 3 and the third positioning block 4 are respectively provided with a first structural groove 16 and a second structural groove 17. The interiors of the first positioning block 2, the second positioning block 3, the third positioning block 4, and the fourth positioning block 5 are respectively provided with a first positioning pin 7, a second positioning pin 8, a third positioning pin 9, and a fourth positioning pin 10. The side of the third positioning pin 9 is provided with two symmetrically arranged strip-shaped protrusions 18.

[0028] Before testing the speed sensor protective cover, multiple positioning blocks are set on the top of the base plate 1. Then, multiple positioning pins are inserted into the multiple positioning blocks respectively. The protective cover is then placed on top of the multiple positioning blocks. Through the matching support of the support block 6 and the first and second shaped grooves 16 and 17, the protective cover can be precisely supported, ensuring accurate positioning and testing of the protective cover.

[0029] In order to enable the rapid assembly or disassembly of the internal components of the inspection fixture, such as Figs. 1-6 As shown, the bottom of the base plate 1 is threaded with multiple connecting bolts 11. The threaded ends of the multiple connecting bolts 11 all pass through the base plate 1 and are respectively threaded into the first positioning block 2, the second positioning block 3, the third positioning block 4, the fourth positioning block 5, and the support block 6. The bottom of the base plate 1 is provided with multiple countersunk grooves 19. The threaded heads of the connecting bolts 11 are located in the countersunk grooves 19. The connecting bolts 11 are internal hex bolts. The top of the base plate 1 is provided with a first positioning groove 12, a second positioning groove 13, a third positioning groove 14, and a fourth positioning groove 15 that are configured to cooperate with the first positioning block 2, the second positioning block 3, the third positioning block 4, and the fourth positioning block 5.

[0030] The multiple positioning slots allow for the determination of the installation positions of multiple positioning blocks. With the cooperation of the connecting bolts 11 and the countersunk grooves 19, multiple positioning blocks can be stably set on the top of the base plate 1. Furthermore, since the connecting bolts 11 can be disassembled, multiple positioning blocks can be quickly separated from the base plate 1, facilitating the replacement or maintenance of the positioning blocks.
