For example, a gear testing fixture proposed in application number "CN202020459028.2" includes a base, a dial indicator mounting seat is installed on one upper surface of the base, and a dial indicator is installed on the dial indicator mounting seat. A gear positioning fixture is installed on the other upper surface of the base. The gear positioning fixture includes a gear mounting shaft for mounting the gear and a support column fixed to the upper surface of the base. A horizontally arranged bushing is installed on the top of the support column. An insertion shaft is coaxially arranged at one end of the gear mounting shaft.

The first friction blocks 506 are respectively engaged inside the grooves 507 and fit against the second friction blocks 508. A transmission block 509 is movably installed through the middle of the inner side of the base plate 1. The front and rear ends of the transmission block 509 are respectively located inside the slide groove 2. The front and rear ends of the transmission block 509 are respectively connected to the push plate 504. The front end of the transmission block 509 is provided with a movable groove 510. The guide rod 9 located in the front slide groove 2 is movably installed inside the movable groove 510. The front end of the front slide groove 2 is provided with a first threaded hole 501.

[0031] The first slider 3 and the second slider 4 can respectively drive the support mechanism 6 and the detection mechanism 7 to move along the slide 2. The spacing between the mechanisms can be flexibly adjusted according to the width of the raw material 8 to achieve stable support for raw materials 8 of different sizes and improve the versatility of the tooling.

[0032] By rotating the handle 503, the first threaded rod 502 is rotated, which pushes the push plate 504 and the first friction block 506 forward, so that they are tightly fitted with the second friction block 508 in the groove 507. Thus, by using friction, the first slider 3 and the second slider 4 are quickly locked together, avoiding displacement during the detection process and ensuring detection stability.

[0033] By selecting different positioning holes 603 to install the second threaded rod 604 and locking it with nut 605, the support frame 602 can be adjusted in multiple stages in height and front-back direction to adapt to the installation requirements of gears of different specifications and enhance the adaptability of tooling.

[0034] When it is necessary to adjust the height of the dial indicator or micrometer, loosen the first bolt 704, move the movable block 702 to the position of the second fixed block 701, and then tighten the first bolt 704 to achieve precise adjustment of the indicator chuck 712 in the horizontal direction, which facilitates alignment with the gear detection point and improves detection accuracy.

[0035] When it is necessary to adjust the dial indicator or micrometer indicator to the front or back end, loosen the second bolt 710, and then the user can slide the support block 707. After moving it to the designated position, tighten the second bolt 710 to achieve flexible adjustment of the gauge clamp 712 and ensure accurate contact between the measuring head and the gear measuring surface.

[0036] The working principle of this gear inspection fixture:

[0037] In use, firstly, based on the width of the raw material 8, push the first slider 3 and the second slider 4 along the slide groove 2, thereby adjusting the support mechanism 6 and the detection mechanism 7 to a suitable distance. Then, by turning the handle 503, the first threaded rod 502 is rotated, pushing the push plate 504 and the first friction block 506 forward, so that they are tightly fitted with the second friction block 508 in the groove 507. The friction force is used to quickly lock the first slider 3 and the second slider 4, ensuring that no displacement occurs during the detection process. Then, the support mechanism 6 and the detection mechanism 7 are finely adjusted according to the height of the raw material 8 and the position of the detection point. By selecting different positioning holes 603 to install the second threaded rod 604 and locking it with the nut 605, the height of the support frame 602 can be adjusted. Then, by loosening the first bolt 7... 04. The user controls the movable block 702 to move the first guide block 706 up and down to adjust the height between the dial indicator 712 and the raw material 8. After adjustment, the user tightens the first bolt 704. Then, the user loosens the second bolt 710 and pushes the support block 707 to move the second guide block 708 back and forth to control the vertical overlap between the dial indicator 712 and the raw material 8 at the required detection position. Then, the user tightens the second bolt 710 and places the raw material 8 between the two support frames 602. At the same time, the dial indicator or micrometer is installed on the dial indicator 712. Then, the user fine-tunes the position of the movable block 702 and the support block 707 until they are in contact with the detection surface of the raw material 8. Then, the angle consistency of the raw material 8 can be detected.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
