Description

Linear Bearing Assembly Machine

technical field

The invention relates to the technical field of automobile manufacturing, and more specifically relates to a linear bearing assembly machine.

Background technique

In the gearbox of an automobile, the shift fork is usually first welded to form a shift fork, and then the linear bearing is installed in the slot of the shift fork rod, and finally the shift fork with the linear bearing is loaded into the gearbox.

At present, linear bearings are assembled manually. Specifically, workers use open-ended pliers to stretch the elastic bushing from the opening of the linear bearing and put it on the shift fork rod, and then slowly knock the linear bearing into the slot by tapping. During the entire assembly process, it is necessary to repeatedly adjust the attitude of the linear bearing. The assembly is too complicated and takes a lot of time, resulting in low assembly efficiency.

In addition, the opening size of the bushing cannot be precisely controlled by using open pliers to manually stretch the elastic bushing. Excessive stretching of the opening will cause permanent deformation of the elastic bushing. After installation, the steel balls of the linear bearing cannot slide smoothly, and the installation quality is poor.

To sum up, how to assemble the linear bearing to improve the assembly efficiency of the linear bearing is an urgent problem to be solved by those skilled in the art.

The working process of the linear bearing assembly machine provided by the embodiment of the present invention is as follows: the linear bearing is placed on the pulling assembly, and the parts to be installed are placed on the bracket 7; the first driving part 1 drives the pulling assembly to pull the elastic bushing of the linear bearing, and then the second driving part 5 drives the bracket 7 to move, and the parts to be installed on the bracket 7 move with the bracket 7; On the installation part; the third driving part 17 drives the pull-out assembly to continue to move, and since the pulled-off elastic bush is sleeved on the part to be installed, the separation of the pull-off assembly and the linear bearing is realized, that is, the assembly is completed.

It can be understood that, in order to carry out the next assembly, the pulling assembly needs to be reset. Specifically, the third driving part 17 drives the pulling assembly to reset, and the first driving part 1 drives the pulling assembly to reset, then the third driving part 17 drives the pulling assembly to reciprocate, and the first driving part 1 drives the pulling assembly to reciprocate.

It can be seen from the above working process that the linear bearing assembly machine provided by the embodiment of the present invention is beneficial to the first driving part 1 to drive the pulling assembly to pull the elastic bushing of the linear bearing, and the linear bearing with the elastic bush pulled apart is directly placed on the component to be installed by moving the component to be installed and the pulling component, so that the assembly can be completed at one time. Compared with the prior art, the assembly is simplified and the assembly efficiency is improved.

At the same time, the linear bearing assembly machine provided by the embodiment of the present invention uses the first driving part 1 to drive the pull-out assembly to pull apart the elastic bush of the linear bearing. Compared with the elastic bush of the linear bearing manually stretched in the prior art, it is easier to control the pull-out size of the elastic bush, improves the control accuracy, reduces the probability of permanent deformation of the elastic bush and the probability that the steel ball of the linear bearing cannot slide smoothly, and effectively improves the installation quality.
