Abstract

The invention discloses vacuum press fitting equipment suitable for interference assembly of a shaft part provided with a blind hole. The vacuum press fitting equipment comprises a mounting plate and a housing fixed to the mounting plate; a control system is arranged in the housing; and a display and start buttons are arranged on the outer wall of the housing. The vacuum press fitting equipment further comprises a press fitting chamber, a cover plate driving mechanism, a vacuum mechanism and a press fitting transmission mechanism which are arranged in the housing, as well as a cover plate arranged over the press fitting chamber and arranged at the exterior of the housing. The vacuum press fitting equipment is particularly suitable for the small-size shaft part to be rapidly and stably pressed into the blind hole; a press fitting tool is driven by an air cylinder, and air cylinder push force is converted to press fitting force of the shaft part, so that the interference assembly is completed effectively. In addition, positions of a shaft and a hole are automatically located, action like vacuumizing and press fitting in the press fitting chamber is realized through PLC control, and automatic and semi-automatic press fitting assembly can be realized.

Description

technical field [0001] The utility model belongs to vacuum press-fitting equipment, which is suitable for vacuum press-fitting equipment for interference assembly of shaft parts with blind holes. Background technique [0002] Vacuum press-fitting equipment is used to complete the interference assembly of parts in a vacuum environment. Press-fitting process of shaft parts with blind holes, such as figure 1 As shown, when the slender shaft part 28 is interference-fitted into the blind hole with the blind hole part 27 to obtain the press-fitted part 29, the air in the blind hole with the blind hole part 27 will affect the press-fit depth, thereby affecting Assembly quality. The above-mentioned problems can be avoided by using vacuum press-fitting equipment. [0003] At present, most of the press-fitting equipment on the market are for press-fitting larger parts, most of which are in the field of bearing installation. It is not suitable for interference press-fitting of smal...
