Steering and shifting device of moving trolley

Abstract

The invention discloses a steering and shifting device of a moving trolley. The steering and shifting device is characterized by comprising the moving trolley moving left and right along a base, wherein two workbenches are arranged on the moving trolley side by side; rollers are arranged on the lower end faces of the workbenches; two groups of first rails matched with the rollers side by side are fixedly arranged on the upper end face of the moving trolley; the first guide rails extend in the front and back direction and are perpendicular to the moving direction of the moving trolley; a positioning mechanism is arranged between the workbenches and the moving trolley; a trolley movement driving mechanism is arranged inside the moving trolley; a workbench movement driving mechanism for driving the workbenches to move front and back is arranged on a punch pedestal. The steering and shifting device can directly drive the workbenches to move front and back to the punch pedestal instead of moving the trolley front and back; compared with the conventional steering and shifting device, the steering and shifting device can eliminate a hoisting oil cylinder, so as to lower the cost and avoid maintenance to the oil cylinder; furthermore, the workbench movement driving mechanism adopts the motor and chains, so that the steering and shifting device is high in transmission stability, simple in structure, convenient to mount and maintain, and low in cost.

Description

technical field [0001] The invention relates to a mobile trolley used for mold replacement in punch processing, in particular to a steering and moving device for the mobile trolley. Background technique [0002] The mobile trolley is a commonly used equipment for changing molds in punch processing. It consists of a worktable and a mobile trolley. When the punching machine needs to change the mold, first remove the mobile trolley and the mold in the punching machine, and then move the mobile trolley with another pair of molds into the punching machine, and the mobile trolley needs to move at 90 degrees during this movement process. Turn to move. At present, the steering movement of the mobile trolley is basically provided with front and rear rails and left and right rails with a height difference in the foundation. The oil cylinder lifts the mobile trolley to ensure that the wheel height of the mobile trolley matches the height of the left and right rails, and then the mob...

AI Technical Summary

Problems solved by technology

The steering and moving device of the above-mentioned mobile trolley needs to install four lifting oil cylinders at the turning point of the track, but the configuration cost of the oil cylinders is high, the quality stability is not high, and because the oil cylinders are installed in the foundation, it is inconvenient to install and maintain; in addition, Since the mobile trolley uses bevel gears to transmit power, eight sets of gears are required during the entire moving process, which requires relatively high processing and installation requirements for the gears, and the processing cost is high and maintenance is inconvenient.
