The internal CV joint includes thousands of different parts, from large floorboards to small screws. The actual automobile production process is completed by the cooperation of several different specialized manufacturers. In order to manufacture automobiles economically and efficiently, these specialized manufacturers organize production and cooperate according to the principle of product collaboration. Generally speaking, major assemblies such as engines, transmissions, axles, and bodies are manufactured by the company itself, while tires, glass, electrical components, interior body parts, and other small parts are mostly produced by external specialized factories through cooperation.

[0003] In the automotive industry, in order to ensure the accuracy of the produced inner CV joints, it is often necessary to measure the distance of the produced inner CV joints. Existing distance measuring components have problems such as complicated operation methods for some parts and high cost for others. On the other hand, some parts distance measuring devices with reasonable cost and relatively simple operation methods have problems with large errors. Therefore, it is necessary to have a parts distance measuring device that is simple to operate, has small errors, and is relatively affordable. Summary of the Invention

[0004] This invention proposes an internal ball cage diameter measuring device for automobile production, which solves the problems of cumbersome operation, high cost and large error of existing distance measuring devices.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-6 In this first embodiment, an inner ball cage diameter measuring device for automobile production includes a base, a support rod, and an inner ball cage.

[0027] The support rod 2 is welded with a ranging sleeve 4. The ranging sleeve 4 is annular with a hollowed-out circular hole in the middle. During the inner ball cage test, the smaller end of the part to be tested is placed downwards from the middle of the ranging sleeve 4, so that the bottom of the larger end of the part to be tested fits the inner circle of the top of the ranging sleeve 4, thus making the center of the part to be tested coincide with the center of the ranging sleeve 4, which facilitates subsequent testing. A bottom placement sleeve 5 is welded to the upper surface of the base 1 and corresponding to the ranging sleeve 4. The bottom placement sleeve 5 is aligned with the ranging sleeve 4 and parallel to the center of the ranging sleeve 4. When the part to be tested is placed in the middle of the ranging sleeve 4, the lower part of the part to be tested is located in the inner cavity of the ranging sleeve 4, thus cooperating with the ranging sleeve 4 to ensure the verticality of the part to be tested. The right side wall of the ranging sleeve 4 is horizontal. A right-side fixing screw 6 is movably connected to the sleeve. The right-side fixing screw 6 has threads on its body. The inner cavity of the ranging sleeve 4 has corresponding serrations at the contact point with the body of the right-side fixing screw 6. The threads of the right-side fixing screw 6 mesh with the serrations on the cylinder wall of the ranging sleeve 4. A right-side handle 7 is welded to the right end of the right-side fixing screw 6. By turning the right-side handle 7, the user can move the right-side fixing screw 6 along the serrations on the cylinder wall of the ranging sleeve 4. It laterally penetrates the support rod 2 and the rear wall of the ranging sleeve 4. A rear fixing screw 8 is movably connected to the support rod 2 and the rear wall of the ranging sleeve 4. The rear fixing screw 8 has threads on its body. The inner cavity of the ranging sleeve 4 has corresponding serrations at the contact point with the body of the rear fixing screw 8. The threaded joint engages with the serrated wall of the ranging sleeve 4. A rear handle 9 is welded to the rear end of the rear fixing screw 8, allowing the user to rotate the rear fixing screw 8. A ranging main rod 10 is movably fitted into the inner cavity of the left side of the ranging sleeve 4. A left-side handle 11 is fixedly installed on the left end of the ranging main rod 10. A main rod limiting block 12 is welded to the right end of the ranging main rod 10 and movably fitted into the inner cavity of the left side of the ranging sleeve 4. The main rod limiting block 12 is movably placed in the inner cavity of the ranging sleeve 4, fixing the ranging main rod 10 in its current position. When the user rotates the left-side handle 11, the ranging main rod 10 rotates in place. A ranging component 13 is movably fitted into the inner cavity of the left end of the ranging main rod 10. The left end of the ranging component 13 is located in the inner cavity of the ranging main rod 10, and the right end is positioned to the right. The distance measuring component 13 extends through the inner cavity of the main measuring rod 10 and the measuring sleeve 4, and is movably sleeved within the inner cavity of the main measuring rod 10 and the measuring sleeve 4. When the user rotates the main measuring rod 10, the distance measuring component 13 rotates accordingly. A rotating gear 14 is engaged at the bottom of the distance measuring component 13. When the distance measuring component 13 starts to move, it will drive the rotating gear 14 to rotate. A rotating rod 15 is welded to the front end of the rotating gear 14. A dial 16 is fixedly installed on the front side of the main measuring rod 10. When the rotating gear 14 rotates, it transmits the rotational force to the pointer inside the dial 16 through the rotating rod 15, causing the pointer to deflect. Thus, the user can know the distance that the distance measuring component 13 has moved by reading the degree of the pointer, thereby connecting the diameter of the part to be measured to complete the testing of the part.

[0028] The ranging main rod 10 has a ranging screw 131 movably fitted inside the right end cavity. The left end of the ranging screw 131 is located inside the right end cavity of the ranging main rod 10. The right end of the ranging screw 131 extends to the right out of the wall of the ranging sleeve 4, and the rod body of the ranging screw 131 is threaded. The corresponding contact position between the inner cavity of the wall of the ranging sleeve 4 and the rod body of the ranging screw 131 is serrated. The thread of the rod body of the ranging screw 131 and the serration of the wall of the ranging sleeve 4 mesh with each other. A limiting support rod 132 is welded to the left end of the ranging screw 131 inside the cavity of the ranging main rod 10. A ranging limiting block 133 is welded to the outer wall of the limiting support rod 132. The inner cavity of the ranging main rod 10 is adapted to the ranging limiting block 133, so that when the ranging main rod 10 rotates, the limiting support rod 132 rotates synchronously.

[0029] When using the part diameter measuring device, the user first places the inner ball cage to be measured from top to bottom inside the measuring sleeve 4, so that the bottom of the part is placed in the inner cavity of the bottom placing sleeve 5. Since the measuring sleeve 4 is annular with a circular middle part, after the inner ball cage is placed, the larger end of the inner ball cage falls onto the upper surface of the measuring sleeve 4, so that the lower part of the inner ball cage is located in the middle part of the measuring sleeve 4. Then the user turns the right handle 7, the rear handle 9, and the left handle 11. When the right handle 7 and the rear handle 9 are turned, the right fixing screw 6 and the rear fixing screw 8 move along the inner wall thread of the measuring sleeve 4 towards the inner ball cage and finally fit against the outer wall of the inner ball cage. When the left handle 11 is turned, the measuring main rod 10 rotates accordingly. Due to the limitation of the main rod limiting block 12, the measuring main rod 10 rotates in place. As the measuring main rod 10 rotates, the measuring sleeve in the inner cavity of the measuring main rod 10 moves. Due to the limitation of the ranging limit block 133, the ranging screw 131 rotates with the ranging main rod 10. The section of the ranging screw 131 that contacts the inner wall of the ranging sleeve 4 meshes with each other. When the ranging screw 131 rotates, it moves along the serrations of the inner wall of the ranging sleeve 4, and finally the right end of the ranging screw 131 abuts against the outer wall of the inner ball cage. Since the three screws abut against the outer wall of the inner ball cage, the inner ball cage is fixed in the middle position. Due to the movement of the ranging screw 131, the rotating gear 14 that meshes with the bottom of the ranging screw 131 at the top is driven to rotate. The rotation of the rotating gear 14 drives the rotating rod 15 to rotate. Finally, the rotational force of the rotating rod 15 is transmitted to the pointer inside the dial 16, causing the pointer to start rotating. Thus, after the ranging screw 131 finishes moving, it rotates synchronously by the angle of movement. By observing the degree indicated by the pointer on the dial 16 after the movement is completed, the user can easily understand the diameter of the part.
