Gear and rack cylinder with spring buffering function

Abstract

The invention discloses a gear and rack cylinder with the spring buffering function and belongs to the cylinder buffering technical field. A piston and a guide piston are fixedly connected with two ends of a rack respectively; a bolt penetrates a cushion block and the guide piston to enable the guide piston to be fixedly connected with the rack through a baffle plate; a large spring and a small spring sleeve the bolt which is arranged between the inner bottom surface of the guide piston and the cushion block; the inner bottom surface of the guide piston and the cushion block abut against two ends of the large spring respectively and the inner bottom surface of the guide piston and the cushion block abut against two ends of the small spring respectively; the rack is arranged inside a cylinder barrel along with the piston and the guide piston which are arranged at the two ends of the rack respectively; an end cover and a cylinder bottom are connected with two ends of the cylinder barrel respectively. According to the gear and rack cylinder with the spring buffering function, a structure that the cushion block is separated from the guide piston is adopted, the guide piston is not in direct contact with the bottom surface of the cylinder, and accordingly the problems such as the abrasion and the poor sealing effect of the traditional buffer devices are solved.

Description

technical field [0001] The invention relates to a rack and pinion cylinder, in particular to a rack and pinion cylinder with a buffer device, which belongs to the technical field of cylinder buffering. Background technique [0002] In the field of mechanical transmission, the rack and pinion cylinder is a common mechanism that converts linear motion into circular rotation. Ordinary rack and pinion cylinders generally rarely involve adding buffer devices, and even if there is, the buffer effect is not very ideal. For example, if the rubber pad is used, the rubber pad may not be resistant to impact and is easy to age. If the gap seal is used, the sealing effect is not obvious, and the buffer time is easy to lag. Contents of the invention [0003] In view of this, the present invention provides a rack-and-pinion cylinder with spring cushioning. By utilizing the structure that the spacer is separated from the guide piston, the guide piston does not directly contact the bottom...

Problems solved by technology

[0003] In view of this, the present invention provides a rack-and-pinion cylinder with spring cushioning. By utilizing the structure that the spacer is separated from the guide piston, the guide piston does not directly contact the bottom surface of the cylinder, which overcomes the wear and tear of the traditional buffer device and the poor sealing effect.
