[0019] Please refer to Figure 1 , Figure 3 , Figure 4 As shown, the utility model provides a gear testing mechanism, a slide groove 8 is provided on the inner side of the groove of the disc 3, and the groove is provided larger to facilitate position adjustment of a slider 9 on the slide plate 5, one end of the slide plate 5 is placed on the slide groove 8, and the surfaces of the slide groove 8 and the slide plate 5 are smooth enough, a slider 9 is sleeved on the outer side of the slide plate 5, and the slider 9 can move along the slide plate 5, a plurality of limiting holes 10 are provided on the slide plate 5, and the distances between the limiting holes 10 are equal, and a threaded hole 11 is provided on one side of the slider 9, a bolt 12 is threadedly connected to the threaded hole 11, one end of the bolt 12 is fixedly connected to a limiting block 13, and the limiting block 13 can be inserted into the limiting hole 10, a second electric telescopic rod 14 is provided at the lower end of the slider 9, and a second distance measuring sensor 15 is provided at the output end of the second electric telescopic rod 14, a gear 16 is placed on the upper end of the workbench 1, and support legs 17 are fixedly connected at the top corners of the lower end of the workbench 1.

[0020] When in use, the second electric telescopic rod 14 and the second distance measuring sensor 15 can be driven to move by moving the slider 9, and then the distance between the second distance measuring sensor 15 and the first distance measuring sensor 7 can be adjusted, so that the inner and outer diameter tests of gears 16 of different sizes can be conveniently performed. When the slider 9 moves to a suitable distance, the bolt 12 is inserted into the threaded hole 11 and rotated, so that the limit block 13 at one end of the bolt 12 is inserted into the limit hole 10, thereby fixing the slider 9.

[0021] As a further implementation of this embodiment, Figure 1-Figure 4 As shown, a bracket 2 is fixedly connected to the upper end of the workbench 1, a disc 3 is fixedly connected to the center position of the lower end of the bracket 2, a groove is opened at one end of the disc 3, and a motor 4 is arranged at the upper end of the bracket 2, the output end of the motor 4 passes through the bracket 2 and the disc 3 and is fixedly connected to the slide 5, a first electric telescopic rod 6 is arranged at the lower end of the slide 5, and the output end of the motor 4 and the first electric telescopic rod 6 are located in the same vertical direction, and a first distance measuring sensor 7 is arranged at the output end of the first electric telescopic rod 6.

[0022] When in use, by starting the first electric telescopic rod 6, the first electric telescopic rod 6 drives the first distance measuring sensor 7 to move downward and move to the inner diameter of the gear 16, and then starting the motor 4, the motor 4 drives the slide plate 5, the first electric telescopic rod 6 and the first distance measuring sensor 7 to rotate, so that the first distance measuring sensor 7 can rotate one circle to test the inner diameter of the gear 16.

[0023] Specific working principle: when in use, first place the gear 16 at the center of the workbench 1, and then move the slider 9 to drive the second electric telescopic rod 14 and the second distance measuring sensor 15 to move, and then adjust the distance between the second distance measuring sensor 15 and the first distance measuring sensor 7, so that it is convenient to test the inner and outer diameters of gears 16 of different sizes. When the slider 9 moves to a suitable distance, insert the bolt 12 into the threaded hole 11 and rotate it, so that the limit block 13 at one end of the bolt 12 is inserted into the limit hole 10, so as to fix the slider 9, and then start the first electric telescopic rod 6 and the second electric telescopic rod 14, so that the first electric telescopic rod 6 and the second electric telescopic rod 14 respectively drive the first distance measuring sensor 7 and the second distance measuring sensor 15 to move downward, and finally make the first distance measuring sensor 7 and the second distance measuring sensor 15 move downward. The sensor 7 and the second distance measuring sensor 15 are aligned with the gear 16, and then the motor 4 is started. The motor 4 drives the slide plate 5 to rotate. During the rotation, one end of the slide plate 5 slides in the slide groove 8, and the slide groove 8 can provide a certain supporting force for the slide plate 5, so that the slide plate 5 is more stable during the rotation. The rotation of the slide plate 5 indirectly drives the first distance measuring sensor 7 and the second distance measuring sensor 15 to rotate. The first distance measuring sensor 7 and the second distance measuring sensor 15 rotate one circle to complete the accuracy test of the inner and outer diameters of the gear 16. Through this device, not only the outer diameter of the gear 16 can be accurately tested, but also the inner diameter of the gear 16 can be accurately tested. In addition, the distance between the second distance measuring sensor 15 and the first distance measuring sensor 7 on the device can be adjusted, so as to facilitate the testing of gears 16 of different sizes.
