Dual-extruding rod electric cylinder

Abstract

The invention discloses a dual-extruding rod electric cylinder. A front cylinder cover and a rear cylinder cover of the cylinder body are connected onto two ends of the cylinder body via a connection rod; two sides of the cylinder body are provided with trunnion connection plates; one end of a lead screw passes through a nut and a bearing arranged in the center of an end cover to be connected with a motor rotor via a coupler; the above end cover is fixed on a rear cylinder cover via a long screw rod; the other end of the lead screw is sleeved in the bearing fixed on the front cylinder cover; the nut arranged in the center of a sliding block sleeves the lead screw; the inner side of the front cylinder cover is provided with guiding sleeves; one end of each of two extruding rods is fixed on the sliding block respectively, and the other end passes through the guiding sleeve and is extruded out of the front cylinder cover; two extruding end heads are connected via a connection transverse rod; two guiding rods pass through two rear guiding sleeves arranged on the sliding block respectively; and two ends of the two guiding rods are respectively fixed on the front cylinder cover and the rear cylinder cover in the cylinder body. The dual-extruding rod electric cylinder can bear a larger load and can be applied to fields such as industrial processing, aerospace and medical machinery according to different requirements, and the transmission precision is improved.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to an electric cylinder. Background technique [0002] The electric cylinder is a modular product that integrates the servo motor and the lead screw, and it is a new revolutionary product that converts the rotary motion of the servo motor into linear motion. Compared with common hydraulic cylinders and air cylinders, electric cylinders have the advantages of long service life, high transmission precision, quick response, low noise and vibration, strong anti-pollution ability, and convenient maintenance. Therefore, electric cylinders are used in more and more fields, such as industrial processing, aerospace, medical machinery and other fields. But at the same time, ordinary electric cylinders have low load bearing capacity and are difficult to meet the work requirements, and the combination of multiple electric cylinders is often limited by the installation space, which is too complicated a...

AI Technical Summary

Problems solved by technology

But at the same time, ordinary electric cylinders have low load bearing capacity and are difficult to meet the work requirements, and the combination of multiple electric cylinders is often limited by the installation space, which is too complicated and cumbersome. This has become an urgent need in the development process of electric cylinders. one of the problems solved

The invention patent CN104135108A proposes an electric cylinder with a buffer. This invention can reduce the impact of the impact load on the performance of the electric cylinder when subjected to impact, solve the problem of the use limitation of the electric cylinder in the case of impact load, and improve the electric cylinder. The service life of the cylinder, but its transmission accuracy is low
