Vertical type bearing pressing machine

Abstract

The invention discloses a vertical type bearing pressing machine which comprises a base; a rack is arranged on the base; an operation panel is arranged on the rack; a pushing rod drive device is arranged on the top of the rack; the pushing rod drive device comprises a servo motor and a spiral pair; in use, the servo motor drives a lead screw of the spiral pair to rotate and move; a pushing rod is arranged on a nut support of the spiral pair; a guide sleeve is arranged on the outer part of the pushing rod; a central deviation correcting device is arranged on the pushing rod drive device; a quick-to-change pressure head is arranged on the central deviation correcting device; a clamp is arranged on the bottom of the rack; the central deviation correcting device comprises an upper connecting part and a lower connecting part; a thrust ball bearing is arranged between the two connecting parts; a rubber spring is arranged in an inner cavity of the lower connecting part; a bearing clamping mechanism is arranged on the quick-to-change pressure head; the central deviation correcting device is fixed onto a pressure sensor at the lower end of the pushing rod drive device; and the quick-to-change pressure head is connected onto the central deviation correcting device. The vertical type bearing pressing machine is simple in structure, is convenient to operate, is high in assembly precision, is high in efficiency and is high in practicability.

Description

technical field [0001] The invention relates to a bearing or shaft sleeve press-fitting device of a shaft transmission part, in particular to a bearing press-fitting machine used for online automatic press-fitting of automobile gearbox bearings. Background technique [0002] During the assembly process of the automobile transmission system, multiple bearings need to be installed; when assembling the gearbox, the bearings need to be assembled to the housing or the shaft first. [0003] The traditional gearbox bearing assembly mainly adopts manual installation, that is, the gearbox is first fixed on the tooling table, and then the workers use the bushing and hammer to knock the bearing into the bearing hole or on the shaft. Due to artificial uncertain factors such as the size and uniformity of the knocking force, the positioning accuracy is poor, the assembly quality is difficult to control, and it is easy to cause early damage to the bearing, resulting in early failure of the...

AI Technical Summary

Problems solved by technology

Due to artificial uncertain factors such as the size and uniformity of the knocking force, the positioning accuracy is poor, the assembly quality is difficult to control, and it is easy to cause early damage to the bearing, resulting in early failure of the bearing after the gearbox is assembled; at the same time, there is noise pollution. Large, poor working environment, high labor intensity of workers, low assembly efficiency and other defects, it can no longer meet the needs of mass production of automobiles
