Problems solved by technology

[0007] However, limited by the processing accuracy of the fixture itself, the concentricity that can be achieved through the fixture is 0.04mm, and the design requirements are usually 0.02-0.09mm. For phase regulators that require concentricity less than 0.04mm, mechanical The fixture adjustment method cannot meet the requirements

Abstract

The invention discloses a phase adjuster concentricity air inflation adjusting clamp and device, and relates to the technical field of phase adjuster assembly. The clamp and the device aim to solve the problem that a traditional clamp is limited by machining precision so that the concentricity cannot completely meet design requirements. According to the technical scheme, the clamp is characterizedby comprising an adjusting plate, a first supporting column and a second supporting column are arranged on the two sides of the adjusting plate correspondingly, the end, far away from the adjusting plate, of the second supporting column is provided with a positioning column, and an air inflation channel extending to the end face of the second supporting column is formed in the end face of the first supporting column. According to the clamp and the device, the effect of improving the concentricity adjusting precision is achieved so that the concentricity of a stator and a rotor can completelymeet the design requirements.

Description

technical field [0001] The invention relates to the technical field of phase adjuster assembly, and more particularly, to a phase adjuster concentricity inflatable adjusting fixture and device. Background technique [0002] Engine variable camshaft phase adjuster (also known as phase shifter or VCP) is a necessary actuator for automobile engines to realize the variable valve timing VVT function. A certain phase change occurs in the crankshaft. [0003] The existing Chinese patent with the publication number of CN207634122U discloses a special-shaped sealed phase adjuster, which includes a circular stator, a rotor set inside the stator, a cover plate set on the front end surface of the stator, and a rear end surface of the stator. There are several bolt holes on the cover plate, stator, bottom plate and sprocket, which are connected and fixed as a whole by bolts passing through the bolt holes. [0004] Among them, refer to figure 1 and figure 2 , the stator 1 is provided...
