Sealed electric cylinder

Abstract

The invention discloses a sealed electric cylinder which comprises a cylinder, a motor positioned in the cylinder, a lead screw driven through the motor and a slide block matched with the lead screw, and further comprises an elastic seal belt used for sealing the upper side of the cylinder body, wherein the cylinder comprises a cylinder body matched with the slide block; the slide block comprises a slide block body with a slide groove; the side wall of the slide groove extends out of the cylinder body to form a supporting arm; the slide groove is higher than the cylinder body; part of the seal belt is arranged in the slide groove, and the rest of the seal belt is closely clung to the cylinder body. According to the sealed electric cylinder, the technical problem of damage to parts in the electric cylinder due to splashing of a lubricating agent and entry of outside foreign matters into the electric cylinder caused by exposed interior of an existing electric cylinder is solved; the sealed electric cylinder is particularly suitable for working environments with sanitary requirements, and the interior structure of the electric cylinder can be effectively prevented from being exposed.

Description

technical field [0001] The invention belongs to the field of electric cylinders, in particular to a sealed electric cylinder. Background technique [0002] The electric cylinder is a modular product that integrates the servo motor and the lead screw. It converts the rotary motion of the servo motor into linear motion. The sliding structure makes reciprocating linear motion along the guide rail. As the requirements of factory automation are getting higher and higher, the application of electric cylinders is getting wider and wider. Most of the existing electric cylinders are open, and the threaded structure, guide rail and motor of the electric cylinder are all exposed outside, and the lubricant of the electric cylinder will scatter to the outside to cause pollution, and the foreign matter outside is also easy to mix into the electric cylinder inside, thereby damaging the parts inside the electric cylinder. [0003] In addition, the guide rails of existing electric cylinde...

AI Technical Summary

Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that the internal structure of the existing electric cylinder is exposed outside, causing the lubricant of the electric cylinder to scatter to the outside to cause pollution and foreign matter outside is also easily mixed into the interior of the electric cylinder, thus affecting the performance of the electric cylinder. It can work normally or even damage the components in the electric cylinder, so as to provide a sealed electric cylinder that can effectively prevent the internal structure of the electric cylinder from being exposed to the outside
