Description

Technical Field

[0001] The utility model relates to the field of processing equipment, in particular to a bushing press-fitting device. Background Art

[0002] Gearboxes usually need to install shaft sleeves or bushings in the fixing holes to reduce the wear of the shaft and bearing seat. At present, the bushings are mostly assembled by hammering them into the fixing holes of the gearbox. This manual assembly method will result in poor bushing assembly quality, high labor intensity for workers, and low bushing assembly efficiency. To this end, improvements have been made to the bushing press-fitting device in the prior art, as shown in the Chinese utility model "Gearbox Housing Bushing Press-fitting Device" with patent number ZL202221116218.X (authorization announcement number CN217371260U). The bushing press-fitting equipment includes a press-fitting portion that can press-fit the bushing from bottom to top, the press-fitting portion is a fixed end located on the lower side and a press-fitting end located on the upper side and movable relative to the fixed end, a pressing head for placing the bushing is provided at the top of the press-fitting end, and a positioning portion for positioning the bushing is provided on the pressing head, and a limiting device for limiting the movement of the pressing end is also provided at the tail of the fixed end, the limiting device can move the pressing end to a set position and be limited, so that the bushing can accurately control the pressing depth through the cooperation of the pressing head, the positioning portion and the limiting device, thereby avoiding excessive pressing and improving the quality rate of the product.

[0003] Although the above-mentioned bushing press-fitting device can accurately control the pressing depth of the bushing, there are other problems in the actual operation of the bushing press-fitting device. For example, the pressing end in the bushing press-fitting device is prone to displacement during the upward movement for pressing. Although the positioning part can accurately position the bushing in the pressure head, the fixed end drives the pressing end to move upward for a long distance, and the pressing end is prone to displacement during the upward movement, which causes a certain error between the bushing and the fixing hole of the gearbox after being pressed, and thus makes the bushing unstable when pressed in the fixing hole of the gearbox, and is prone to falling off, or the bushing cannot be pressed into the fixing hole of the gearbox, and even the pressing end applies force to press the bushing, which may cause damage to the bushing and the gearbox, affecting the assembly quality of the bushing. For this reason, further improvements need to be made to the bushing press-fitting device. Summary of the invention
