Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shaft parts processing in the machinery manufacturing industry, and specifically relates to an elastic vibration damper for shaft grooving. Background Art
[0002] Shaft grooving is a common machining process, but the current machining equipment produces vibrations, so the shaft grooving is not only inaccurate but also time-consuming. In particular, slender shafts are more prone to cutting vibrations during grooving. Therefore, in order to ensure machining quality, the cutting speed can only be reduced, which seriously affects machining quality and efficiency, and also increases manufacturing costs and reduces the competitiveness of enterprises. Utility Model Content
[0003] The utility model aims to overcome the defects of existing slender shafts in the grooving process and to provide an elastic vibration damper for shaft grooving which has simple structure, convenient use, good vibration reduction effect and low manufacturing cost.
[0004] To achieve the above purpose, the main technical solution provided by the utility model is an elastic shock absorber for shaft grooving, including a shock absorber base, a shock absorber main shaft, a shock absorber pin shaft, a shock absorber roller, a shock absorber spring, an adjusting nut, a cotter pin, and a clamping boss.
[0005] Furthermore, a main shaft of the shock absorber is installed in the hole of the shock absorber base, and two parallel and symmetrical pin holes are provided at one end of the shock absorber main shaft, and the pin holes are respectively installed with shock absorber pins.
[0006] Furthermore, the two shock absorber pin shafts are respectively provided with shock absorber rollers, and one end of the shock absorber pin shaft is provided with a cotter pin.
[0007] Furthermore, a damping spring is mounted on the screw at the other end of the shock absorber main shaft, and a pressure regulating nut is mounted on the screw of the shock absorber main shaft.
[0008] The utility model has the advantages of simple structure, convenient use and stable performance, and can not only effectively improve the production efficiency of shaft grooving processing, but also ensure the processing accuracy of the grooving processing of slender shafts because it is not affected by vibration.
