Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0024] In the figure: upper mold 1; return spring 2; lower mold 3; guide pin 4; spring 5; positioning pin 6; guide column 7

[0025] Such as figure 1 , image 3 Among them, the upper mold 1 and the return spring 2 are connected together, and the lower mold 3, the base, the guide pin 4, the spring 5, and the positioning pin 6 are combined together so that the guide pin can be moved in the guide pin hole of the lower mold 3. Moving up and down in series, the upper mold 1 and the return spring 2 can be aligned with the guide pin holes of the lower mold 3 through the guide pins, and quickly connected together.

[0026] The upper die is a plate-shaped part, the bottom surface of the upper die is fixed to the first end of the guide pin, and the second end of the guide pin passes through the base of the lower die. The bottom surface is opposite, a...

Abstract

The invention provides a bushing press-fitting mold and a bushing press-fitting method, which are easy to manufacture and fast in the press-fitting process, and can further complete the press-fitting process of two or more workpieces at a time. The mold includes a lower mold, a base, an upper mold, a return spring, a guide pin, a guide column, a spring and a positioning pin. The base of the lower mold is welded by steel plates. The column hole and the guide pin move up and down along the hole as the workpiece is pressed; the upper die is welded to the guide pin; the return spring can be fixed on the upper die for easy removal together with the upper die. Place the base of the lower mold on the worktable of the press machine, take the workpieces to be pressed, one piece, two or more pieces at a time, place them on the lower mold through the guide pins, take the upper mold, and put the guide pins and guide pins together. The holes are aligned, the guide pin and the coaxial positioning pin are resisted, and the press is started until the mold stopper is fully in contact, the main shaft of the press goes up, and the upper mold and two finished workpieces are taken out in sequence.

Description

technical field [0001] The invention relates to bushing fittings, especially bushing fittings in the field of vehicles. Background technique [0002] At present, when the company's on-site assembly of the shaft sleeve, the press-fitting process was once changed from the original punching into a single-piece press-fitting, but neither the protection of the parts nor the consistency of the product after assembly can get the most ideal state. Type shaft sleeves need to adjust the distance between the two ends of the shaft sleeve exposed to the mounting hole as required, so as to achieve the best use of the part. Under the current conditions: firstly, the distance between the two ends of the shaft sleeve exposed to the mounting hole cannot be guaranteed 100%; secondly, the efficiency of single-piece press-fitting is not high. Contents of the invention [0003] In order to improve the efficiency of shaft sleeve installation under the existing conditions, adapt to the consisten...
