Embodiment Construction

[0034] In the following, the present invention will be further described by using the following embodiments in conjunction with the accompanying drawings.

[0035] refer to figure 1 and figure 2 , a sealed electric cylinder of the present invention, comprising a cylinder body A, a motor 2 located inside the cylinder body A, a lead screw 3 driven by the motor 2 and a slider 4 cooperating with the lead screw 3,

[0036] The cylinder A includes a cylinder body 1 matched with the slider 4, and the slider 4 has a slider body 41 with a slide groove 411, and the side wall 412 of the slide groove 411 extends outward to the A support arm 413 is formed outside the cylinder body 1, and the groove bottom 414 of the chute 411 is higher than the cylinder body 1;

[0037] It also includes an elastic sealing band 5 for closing the upper side of the cylinder body 1 , the sealing band 5 is partly accommodated in the chute 411 , and the rest is closely attached to the cylinder body 1 .

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...
