DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 As shown, a device for measuring the clearance between a main and a rotated bevel gear comprises: a tool body sleeve 1 having a cylindrical structure. A quick-fix tool is provided within the tool body sleeve 1. The quick-fix tool comprises a fixed sleeve 2 and a rubber sleeve 3. The rubber sleeve 3 is sleeved within the fixed sleeve 2 and has a cylindrical structure with an open first end. The first end of the rubber sleeve 3 extends to the outside of the tool body sleeve 1 to mate with the main shaft in the drive axle to be measured. Due to its elasticity, the rubber sleeve 3 can achieve a tight interference fit with the main shaft. The friction and retractable properties of the rubber sleeve 3 can prevent slipping, maintain the stability of the connection, and achieve a tight connection between the main shaft and the angle encoder as a whole, thereby ensuring that clearance data can be quickly and effectively acquired.

[0025] like Figure 2 As shown, a fixed clamping fixture is provided at the end of the fixed sleeve 2. The fixed clamping fixture includes a fixture body 4 connected to the end of the fixed sleeve 2. Several toggle levers 10 are connected to the outer circumference of the fixture body 4. A clamping portion 5 is provided on the side away from the fixed sleeve 2. The center of the clamping portion 5 has an insertion groove extending downward to penetrate the fixture body 4. Preferably, the fixture body 4 has a circular disc structure and is removably fixed to the fixed sleeve 2 via second bolts 13. There are multiple second bolts 13, evenly distributed along the circumference of the disc-shaped fixture body 4, and the second bolts 13 are located outside the clamping portion 5.

[0026] The first end of the tooling sleeve 1 is equipped with a first tapered expansion sleeve 6, and the second end is equipped with an angle encoder 7. The first tapered expansion sleeve 6 is a frustum with a central opening. The top diameter of the frustum is the same as the outer diameter of the tooling sleeve 1, which ensures a smooth transition between the first tapered expansion sleeve 6 and the end of the tooling sleeve 1.

[0027] The tool body sleeve 1 is provided with a second tapered expansion sleeve 8 and a rotating handle 9. The second tapered expansion sleeve 8 can slide relative to the tool body sleeve 1, and includes an integral bottom plate 81 and an expansion portion 82. Figure 3 and Figure 4 As shown, the base plate 81 is a circular ring that slides over the exterior of the tooling sleeve 1. The expansion portion 82 is integrally connected to one side of the base plate 81 and is circumferentially slotted, dividing the expansion portion 82 into segments. The second tapered expansion sleeve 8 is made of nylon and expands in response to the slots. As the base plate 81 moves toward the first tapered expansion sleeve 6, the first tapered expansion sleeve 6 forces the expansion portion 82 to expand outward.

[0028] The rotary handle 9 is threadedly connected to the tool body sleeve 1, and one end abuts against the side of the bottom plate 81, which can push the second tapered expansion sleeve 8 to move toward the first tapered expansion sleeve 6. A gasket 15 is provided between the bottom plate 81 and the rotary handle 9.

[0029] The angle encoder 7 includes a connecting rod 71, which is inserted into a groove and fixedly connected to the fixed clamping fixture. This securely connects the angle encoder 7 to the spindle, allowing the two to rotate synchronously to measure the spindle's deflection clearance. The angle encoder 7 is removably fixed to the fixture sleeve 1 via a first bolt 12. Furthermore, a threaded hole is defined in the sidewall of the clamping portion 5, which receives a third bolt 14. This third bolt 14 engages the connecting rod 71 downwardly, securing the connecting rod 71 to the fixed clamping fixture.

[0030] A plurality of operating holes 11 are provided on the tool body sleeve 1 at locations corresponding to the toggle rod 10 , so that a worker can reach into the tool body sleeve 1 to toggle the toggle rod 10 .

[0031] Working process: Insert the fixture into the hole of the drive axle center housing, aligning the rubber sleeve 3 with the spindle head and fitting it onto the spindle. Then, rotate the rotary handle 9, causing the second taper expansion sleeve 8 to move toward the first taper expansion sleeve 6 and expand, securing it to the center housing and completing the fixture installation. Next, manually move the toggle lever 10 that secures the fixture left and right, rotating the spindle and angle encoder 7. The corresponding angle value will be displayed on the display connected to the angle encoder 7. The value can be directly obtained and analyzed through PLC analysis and calculation.

[0032] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
