Description

Technical Field

[0001] This utility model relates to the field of mechanical processing and testing technology, specifically to a tooling for testing metal parts. Background Technology

[0002] Metal parts refer to metal components (such as shafts, gears, flanges, etc.) processed through casting, forging, cutting and other processes. Their dimensional accuracy and geometric tolerances directly affect the assembly quality and operating performance of mechanical equipment. Inspection fixtures, through standardized positioning, rapid clamping and integrated measurement functions, can efficiently verify whether the key dimensions of parts are qualified. Compared with traditional manual item-by-item inspection, it can reduce human error, improve inspection efficiency (especially suitable for mass production), and avoid scratches on precision surfaces caused by repeated measurements.

[0003] The "Pin Shaft Inspection Fixture" disclosed in application number "202320464194.5" includes a fixed base plate, a side plate on the upper outer surface of the fixed base plate, a threaded main rod in the middle of the side plate, a pad on the lower outer surface of the fixed base plate, a fixed sleeve on the outer surface of one end of the threaded main rod, a rotating handle on the outer surface of the other end of the threaded main rod, a threaded screw on the outer wall of the fixed sleeve, and a fixing plate on the outer surface of one end of the threaded screw. The pin shaft inspection fixture of this utility model allows the threaded main rod to be rotated and moved via the rotating handle during use, adjusting the distance between the fixed sleeves. This facilitates the fixing of pin shafts of different lengths, and the threaded screw can be used to fix pin shafts of different diameters. Furthermore, the pin shaft can be rotated while adhering to a ball bearing, allowing for rotational inspection of the pin shaft. This design is convenient to use and improves the inspection effect.

[0004] However, the above method still has the following drawbacks: the screw can fix pins of different diameters, but it requires manual operation, which makes it difficult to guarantee positioning accuracy and can easily cause the pin to tilt, affecting the alignment accuracy of the shaft center. When testing axial runout, it will increase the detection error. In addition, the fixing sleeve is fixed at both ends of the pin, which makes it inconvenient to drive the pin. Utility Model Content

By placing a pin between the two support rods 2, the support wheels 3 can support the pin and maintain its centered position. When the pin is long, this prevents it from tilting, ensuring the pin's stability. The shaft alignment accuracy is improved. The anti-slip rubber ring 4 can improve the anti-slip ability of the pin. The synchronous transmission component 7 is driven by the motor 8. The synchronous transmission component 7 can drive the two support rods 2 to rotate synchronously.

The output shaft of the motor 8 can pass through the installation port 14, and rotational friction between the output shaft of the motor 8 and the chassis 6 can be prevented.

[0020] In use, the pin is first placed between the two support rods 2. The support wheel 3 provides support for the pin and keeps it in a centered position. Then, the synchronous transmission assembly 7 is driven by the motor 8 to drive the synchronous wheel 705. The synchronous wheel 705 drives the synchronous wheel 706 to rotate synchronously via the synchronous belt 709. This causes the shaft 701, shaft 702, gear 703, and gear 704 to rotate the two support rods 2 synchronously. The support wheel 3 on the support rod 2 drives the pin to rotate, ensuring the pin's axial alignment accuracy. The anti-slip rubber ring 4 improves the pin's anti-slip ability. The axial runout of the pin can be detected by a runout detector. After the test, the pin can be removed from the support wheel 3. When it is necessary to adjust the distance between the support wheels 3 on the same support rod 2 according to the length of the pin, first push the push plate 507 through the push groove 508 to pull the limit block 503 out of the limit groove 10. The slider 502 can compress the compression spring 505. Then slide the support wheel 3 to adjust the distance between the support wheels 3 on the same support rod 2. The flat opening 9 can prevent the support wheel 3 from rotating on the support rod 2. After that, release the push plate 507, and the compression spring 505 can push the slider 502 to reset. The limit block 503 can be pushed into the corresponding limit groove 10 to quickly fix the support wheel 3. When the support rod 2 drives the support wheel 3 to rotate at low speed, the damping rubber ring 504 can provide sliding damping for the limit block 503, making it less prone to shaking.
