[0002] Against the backdrop of the booming development of modern manufacturing, product quality control has become the key for enterprises to stand firm in the market. As the core tool in the quality inspection process, the performance of inspection tools directly affects the accuracy and efficiency of inspection. In the actual production process, due to the diversification of product types and the continuous improvement of production processes, higher and higher requirements are placed on the adjustability of inspection tools, which need to be able to quickly and accurately adapt to the inspection needs of products of different specifications.
[0003] When inspecting gear mandrels, the commonly used inspection tool fixes the gear mandrel with a fixed shaft and then rotates it to make contact with a micrometer for inspection. However, when inspecting gear mandrels with different inner diameters, the existing inspection tool requires changing different fixing gear mandrel accessories, which makes the inspection tool very inconvenient to use. Therefore, an easily adjustable inspection tool was designed. Summary of the Invention

A worm wheel 504 is fixedly sleeved on the second rotating rod 411 near the worm gear 503. The worm wheel 504 meshes with the worm gear 503. By setting up the driving mechanism 5, the opening and closing of the three L-shaped positioning rods 407 can be controlled when the handwheel 505 is turned, which is convenient for fixing different gear spindles.
[0026] In this utility model, a rectangular frame 3 is fixedly connected to the top of the base 1 near the L-shaped positioning rod 407, and a screw block 303 is slidably connected inside the rectangular frame 3. The same first lead screw 301 is rotatably connected between the two ends of the rectangular frame 3, and the first lead screw 301 is threaded through the screw block 303. A lead screw nut that matches the first lead screw 301 is fixedly sleeved on the screw block 303.

[0028] In this utility model, an adjusting block 6 is screwed onto the circumferential surface of the second lead screw 305, and a lead screw nut that matches the second lead screw 305 is fixedly sleeved on one end of the adjusting block 6. The slide rod 304 slides through the adjusting block 6, and a round hole that matches the slide rod 304 is opened on the adjusting block 6.
[0029] In this invention, a groove is provided on the top of the side of the adjusting block 6 near the adjusting mechanism 4, and an L-shaped plate 602 is slidably connected inside the groove. A third lead screw 603 is rotatably sleeved on the side of the adjusting block 6 away from the adjusting mechanism 4, and the third lead screw 603 is threaded through the L-shaped plate 602. A lead screw nut adapted to the third lead screw 603 is fixedly sleeved on the L-shaped plate 602. A fourth crank 605 is fixedly connected to the other end of the third lead screw 603. A dial indicator 604 is fixedly sleeved on the side of the L-shaped plate 602 near the adjusting mechanism 4. By rotating the fourth crank 605, the dial indicator 604 can approach the gear spindle, which is convenient for contacting different gear spindles for testing.
[0030] Working principle: In use, the gear mandrel to be tested is fitted onto the three L-shaped positioning rods 407. Then, the handwheel 505 of the drive mechanism 5 is rotated, causing the worm gear 503 to rotate with the worm wheel 504. This, in turn, causes the third disc 410, which is fixed to the second rotating rod 411, to rotate with the three protruding rods 412. With the cooperation of the three protruding rods 412 and the slotted hole 409, the three L-shaped positioning rods 407 gradually separate, supporting the inner side of the gear mandrel. This makes the gear mandrel coaxial with the second disc 405. By adjusting the mechanism 4, gear mandrels of different sizes can be quickly fixed, ensuring stable rotation of the gear mandrel without the need for replacement. The components are then adjusted by rotating the second crank 302, bringing the adjusting block 6 closer to the gear spindle. Next, rotating the third crank 307 brings the dial indicator 604 closer to the gear spindle. Then, rotating the fourth crank 605 brings the L-shaped plate 602, along with the dial indicator 604, closer to the gear spindle, so that the measuring end of the dial indicator 604 contacts the outer circumference of the gear spindle. Finally, rotating the first crank 402 of the adjusting mechanism 4 causes the second disc 405 and the three L-shaped positioning rods 407 to rotate together with the gear spindle. Through contact with the dial indicator 604, the verticality of the radial runout can be observed on the dial indicator 604, thus determining whether the gear spindle is qualified.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
