Problems solved by technology

In order to increase the working stroke, the length of the push rod and the cylinder needs to be lengthened, resulting in bulky equipment and high manufacturing costs
In some occasions that require small installation size and long working stroke, single-stage electric cylinders often cannot meet the requirements of use.

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 , figure 2 , image 3 As shown, a two-stage electric cylinder with integral movement of the motor includes the cylinder bottom 2, the outer cylinder 13 is installed on the cylinder bottom 2, the first screw rod 29 is fixed in the middle of the cylinder bottom 2, and the cover plate 1 connects the cylinder bottom 2 and the second cylinder bottom. A screw rod 29 is connected together, and the first rotating drum 5 is installed on the first screw rod 29. The rear section of the first rotating drum 5 has an internal thread inside, and is threadedly matched with the first screw rod 29. The front section of the first rotating drum 5 There are external threads on the outside, and are threadedly matched with the first nut 9. The motor rear end cover 4 and the motor front end cover 8 are installed on the first drum 5 through the first thrust bearing...

Abstract

The invention discloses a motor wholly-moving type two-level electric cylinder. A motor and a transmission system are integrally design, so that the motor wholly moves. The electric cylinder can achieve two-level transmission, a first-level threaded rod is fixed, a motor rotor can drive a first rotating barrel to rotate, and a first sleeve is pushed out through a motor front end cover; meanwhile, due to the fact that a first nut can move forwards in the axial direction along with rotation of the first rotating barrel, a second sleeve is pushed out, and then two-level pushing is finished. The electric cylinder has the advantages of being capable of being integrally designed, simple in structure, convenient to maintain, good in servo control performance, long in working stroke and the like.

Description

technical field [0001] The invention belongs to the technical field of electric cylinders, and in particular relates to a two-stage electric cylinder with integral movement of a motor. Background technique [0002] The electric cylinder is a device that converts the rotary motion of the servo motor into the linear motion of the working mechanism. The electric cylinder has simple structure, good servo control performance and wide application. [0003] Ordinary electric cylinders generally design the transmission system first, and then select the motor according to the work requirements. The transmission system and the motor of this electric cylinder are separated, with low integration, large space occupation and high cost. In order to facilitate centralized lubrication and maintenance and reduce the size of the electric cylinder, it is imperative to realize the integrated design of the motor and transmission cylinder. [0004] The single-stage electric cylinder is limited b...
