Roller shaft sleeve pre-assembly production equipment

Abstract

The invention discloses a roller shaft sleeve pre-assembly production equipment and belongs to the field of roller pre-assembly. According to an existing shaft sleeve butt joint process, inaccurate butt joint is likely to be brought about; when a shaft sleeve is pressed in a later period, the shaft sleeve deviates easily; and as a result, the percent of pass of roller assembly is low. According tothe technical schemes of the invention, the roller shaft sleeve pre-assembly production equipment comprises a lower rotary disc, an upper rotary disc, a shaft sleeve butt joint mechanism located on the edge of the lower side face of the upper rotary disc, and a discharging mechanism located on the upper side face of a fixing table; the shaft sleeve butt joint mechanism comprises a limiting plate,a magnet block, a pushing plate and a guide rail groove; the limiting plate is welded and fixedly connected to the edge of the lower end face of the upper rotary disc through a supporting rod; the magnet block is embedded in the surface of one side of the limiting plate; the pushing plate is welded and fixed to the bottom end face of a guiding rod; the guide rail groove is formed in the inner wall of an outer frame; and a guiding wheel is connected into the guide rail groove in a sliding manner. With the roller shaft sleeve pre-assembly production equipment of the invention adopted, a rollerand a shaft sleeve can be pre-assembled; assembling precision is high; the rapid press fit of the roller and the shaft sleeve in a later period is facilitated; and the percent of pass of roller assembling is increased.

Description

technical field [0001] The invention relates to the field of pre-assembly of rollers, in particular to pre-assembly production equipment for roller bushings. Background technique [0002] Rollers are often used in the machinery industry to convey profiles. Its structure is usually composed of a hub and a rubber wheel fixed outside the hub. In order to be used alone, a wheel frame is added outside the roller to form a roller assembly. Install the shaft sleeve to facilitate the installation of the roller and the shaft. At present, the shaft sleeve is usually docked manually. Due to the small diameter tolerance of the shaft sleeve and the inner hole of the roller, it is easy to cause inaccurate docking during the docking process. , it is very easy to cause the shaft sleeve to deviate, so that the qualified rate of the roller assembly is low. Therefore, a pre-assembled production equipment for the roller shaft sleeve is proposed. Contents of the invention [0003] The purpose...
