[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a conversion device for the reference positioning member of an automotive sheet metal part inspection fixture, including an inspection fixture housing 1. The inspection fixture housing 1 is the main structure of the inspection fixture for inspecting automotive sheet metal parts. An installation plate 6 is abutted against the front side of the inspection fixture housing 1. The installation plate 6 is used to fixedly install a sleeve 3. The installation sleeve 3 is fixedly connected to the front side of the installation plate 6. The installation sleeve 3 functions to install a positioning pin 2. A positioning pin 2 is slidably connected inside the installation sleeve 3. The positioning pin 2 is used to position the automotive sheet metal part. Two clamping blocks 5 are slidably connected inside the upper and lower sides of the installation plate 6 respectively. The front part of the clamping block 5 is slidably connected to the front side of the clamping block 5, and the rear part of the clamping block 5 is slidably connected inside the inspection fixture housing 1. The clamping block 5 can connect the installation plate 6 and the inspection fixture housing 1 to each other. One side of the clamping block 5 is fixedly connected to a first spring 7. One end of the first spring 7 is fixedly connected inside the installation plate 6. The first spring 7 is used to push the clamping block 5 to move. One side of the clamping block 5 is fixedly connected to a baffle 10. The baffle 10 is slidably connected inside the installation plate 6. The baffle 10 can block impurities from entering the inside of the installation plate 6 and prevent the normal movement of the clamping block 5. One side of the baffle 10 is fixedly connected to a first limiting plate 8. A plurality of first limiting grooves 9 are formed inside the installation plate 6. The first limiting plate 8 is slidably connected inside the first limiting groove 9. The sliding of the first limiting plate 8 inside the first limiting groove 9 can limit the movement of the baffle 10.

[0034] Referring to Figure 1 , Figure 4 and Figure 5 , an adjusting component is arranged inside the installation sleeve 3. The adjusting component is used to adjust the length of the positioning pin 2. The adjusting component includes a fixed block 12. The fixed block 12 is fixedly connected inside the installation sleeve 3. A sliding groove 11 is formed inside the positioning pin 2. The fixed block 12 is slidably connected inside the sliding groove 11. The sliding of the fixed block 12 inside the sliding groove 11 can drive the positioning pin 2 to move. A turntable 4 is fixedly connected to the right end of the positioning pin 2. Rotating the turntable 4 can drive the positioning pin 2 to rotate. A plurality of convex blocks 14 are slidably connected inside the positioning pin 2. Two grooves 15 are formed inside the top end of the fixed block 12. The convex blocks 14 are arranged inside the grooves 15. After the convex blocks 14 are inserted into the grooves 15, the position of the positioning pin 2 can be fixed. One side of the convex block 14 is fixedly connected to a second limiting plate 16. A second limiting groove 17 is formed inside the positioning pin 2. The second limiting plate 16 is slidably connected inside the second limiting groove 17. Installing the second limiting plate 16 and making the second limiting plate 16 slide inside the second limiting groove 17 can prevent the convex blocks 14 from falling off the inside of the positioning pin 2. One side of the second limiting plate 16 is fixedly connected to a second spring 13. One end of the second spring 13 is fixedly connected inside the positioning pin 2. The second spring 13 functions to push the convex blocks 14 to move.

[0035] Working principle: Before detecting the automobile sheet metal parts, rotate the positioning pin 2 of appropriate size according to the usage requirements. Then, press two adjacent blocks 5 to move towards each other and make the mounting plate 6 contact with the fixture housing 1, so that the rear parts of multiple blocks 5 are inserted into the interior of the fixture housing 1. After that, release the blocks 5, and multiple blocks 5 can be respectively pushed by multiple first springs 7 to connect the mounting plate 6 and the fixture housing 1 with each other, thus completing the rapid installation of the positioning pin 2.

[0036] After the installation of the positioning pin 2 is completed, the turntable 4 can be rotated to drive the positioning pin 2 to rotate. During the rotation of the positioning pin 2, the fixed block 12 slides inside the chute 11, thereby driving the positioning pin 2 to move towards the left end of the mounting sleeve 3. When the fixed block 12 moves to the end of the chute 11, two bumps 14 inside the positioning pin 2 can be respectively pushed by two second springs 13 to be inserted into two grooves 15, so as to fix the position of the positioning pin 2. After the positioning pin 2 is removed from the interior of the mounting sleeve 3, it can play a role in positioning the automobile sheet metal parts. Then, the positioning pin 2 can be used to position the automobile sheet metal parts for detection.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
