Description

Technical Field

[0001] The utility model relates to the field of transmission shaft detection, and more specifically, to a transmission shaft roughness detection device. Background Art

[0002] The drive shaft is a high-speed, less-supported rotating body, so its dynamic balance is very important. Generally, the drive shaft must be tested for dynamic balance before leaving the factory and adjusted on a balancing machine. For front-engine, rear-wheel-drive vehicles, it is the shaft that transmits the rotation of the transmission to the main reducer. It can have several sections, and the sections can be connected by universal joints. However, the drive shaft also needs to be tested for roughness after production to screen the complete drive shaft;

[0003] After searching, the existing patent (Announcement No.: CN218097702U) discloses a surface smoothness detection device for transmission shaft processing, including a detection table, a slide groove is provided on the detection table, an adapter block is slidably connected in the slide groove, a driving component for adjusting the lateral position of the adapter block is arranged on the outer side of the detection table, a special-shaped frame is arranged on the adapter block, a first telescopic push rod is arranged on the special-shaped frame, a receiving part is arranged at the output end of the first telescopic push rod, a second telescopic push rod is arranged on the outer side of the receiving part, and a surface roughness detector is arranged at the output end of the second telescopic push rod. The surface smoothness detection device for transmission shaft processing can make the chuck clamp the transmission shaft body by turning the adjustment wheel to avoid manual pressing, and the drive motor can be operated to adjust the position of the surface roughness detector to detect different positions of the transmission shaft body. Since the adjustment is completed mechanized, the worker's hands are freed, making the detection work easier to complete. The inventor found that the prior art has the following problems in the process of realizing the utility model:

[0004] When the existing transmission shaft roughness detection device is used in the later stage, since the current transmission shaft is mostly picked up manually and then rotated manually during detection, this will increase the labor intensity of the workers and the work efficiency is not high. In addition, there is often no limit rotation mechanism to limit the rotation of the transmission. At the same time, the above-mentioned patent comparative document only proposes to limit the transmission shaft by machinery, but does not propose a technical solution that can also be rotated when limiting.

[0005] Therefore, in order to solve the above problems, a transmission shaft roughness detection device is proposed. Utility Model Content
