Multi-station oil press

Abstract

The invention provides a multi-station oil press. The multi-station oil press comprises an oil press body and station tools, a tip device is mounted on an upper pressure head of the oil press, a lowerpositioning oil cylinder is mounted in a base of the oil press in the mode of being coaxial with the upper pressure head, the tip device is arranged on the positioning oil cylinder, a multi-station rotation worktable is mounted on a worktable of the oil press, the lower part of the multi-station rotation worktable is provided with a circular steel structure chassis, a rotating disc is arranged onthe chassis, a hydraulic motor and a gear are arranged in the middle of the rotating disc, an internal-tooth-type rotary bearing is arranged in the mode of being matched with the hydraulic motor andthe gear, the rotating disc is connected to the station tools through connecting pins, each station tool is connected with the rotating disc through the two corresponding connecting pins, the lower parts of the station tools are provided with idler wheels, polyurethane springs and positioning nylon sleeves, positioning holes are formed in the positions, in front of each station tool, on the rotating disc, and a positioning pin is arranged below one of the positioning holes and above the chassis correspondingly. The multi-station oil press is provided with a plurality of stations, shrinkage fitting, cooling and press fitting can be achieved on one machine, and accurate positioning and press fitting can be achieved; and the structure is reasonable, and the efficiency is improved.

Description

technical field [0001] The invention relates to a forging machine, in particular to a multi-station hydraulic press. It is mainly used for the press-fitting of large gear bearings, oil deflector rings and collector rings of integral gearboxes. Background technique [0002] It is understood that the integral gearbox large gear bearings, oil deflector rings and collector rings on the train axle are now press-fitted with ordinary hydraulic presses. It has only one station and can only press-fit the bearings. Due to the time limit, workers must send it into the hydraulic press very punctually, so that it can be pressed and installed in place later. However, due to the rush to hoist in a hurry, it is easy to cause danger. Contents of the invention [0003] In order to solve the problem of insufficient existing technology, the present invention provides a multi-station hydraulic press, which has a reasonable structure and strong practicability. Positioning and pressing. [00...

Problems solved by technology

[0002] It is understood that the integral gearbox large gear bearings, oil deflector rings and collector rings on the train axle are now press-fitted with ordinary hydraulic presses. It has only one station and can only press-fit the bearings. Due to time constraints, workers are required to send them into the hydraulic press very punctually, so that they can be press-fitted in place later. However, due to the rush to hoist in a hurry, it is easy to cause danger
