Embodiment

[0031] like Figure 1-Figure 5 As shown, through the cooperation of the gland 1 and the pressure-bearing base 4, a certain clamping force is provided to the vibration-damping bearing raceway ring 5 during the entire tempering process, and the deformation space of the vibration-damping bearing raceway ring 5 is limited. , On the premise of reliably completing the tempering process, the deformation can be controlled, thereby improving the qualified rate of the product. The vibration-damping bearing race rings 5 ​​can be clamped on the clamping main body 7 in a stacked form, so that the single processing quantity is large and the processing efficiency is improved.

[0032] like Figure 1-Figure 5 As shown, at least one viewing port 11 is provided on the side of the gland 1 , and the viewing port 11 extends radially to communicate with the insertion groove 13 . It is used to observe the depth of the clamping body 7 inserted into the insertion groove 13, to ensure that the clampi...

Abstract

The invention relates to the field of bearing processing, and specifically discloses a tempering processing technology for a channel ring of a damping bearing. A tempering clamping tool is adopted, wherein the tempering clamping tool includes a cylindrical clamping body, the outer cylindrical surface of the clamping body is provided with a pressure-bearing base, and the pressure-bearing base is distributed in a ring around the axis; It also includes a gland, the gland and the limit seat are set separately, and the gland is provided with an insertion groove; in the clamping state, one end of the clamping body is inserted into the insertion groove, and is connected with the pressure The cover is connected, and there is a clamping space between the press cover and the pressure-bearing base. Adopting the above-mentioned tempering process of the raceway ring of the damping bearing can reduce the amount of deformation of the product during the tempering process and improve the qualified rate of the product.

Description

technical field [0001] The invention relates to the field of bearing processing, in particular to a tempering process for a race ring of a damping bearing. Background technique [0002] The shock absorber bearing is an important part of the shock absorber, usually including an upper cover, a lower cover and a thrust ball. In order to achieve lightweight design and be more suitable for suspension working conditions, most of the shock absorber bearings adopt a composite structure, in which the upper and lower covers are made of plastic for tough buffering, and the race ring is made of metal as a rotating part and bears the load. [0003] Since the channel rings are all thin and large (the general size is more than 80mm, and the plate thickness is less than 2mm), the heat treatment deformation is large and the failure rate is high. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a tempering process for the channel ...
