Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] In the figure, the bearing sleeve (5) is installed together with the screw nut pair (3) by interference fit, and the rotor (10) and the screw nut pair (3) are connected through the A-shaped flat key (17). The sleeve (6) and the B-type shaft are axially positioned with a circlip (11), and the stator (9) is pressed into the bearing seat (8) by a press, and is fixed through the protruding stop of the encoder box (12). Compress to meet the axial positioning, the bearing (7) and the bearing (13) are installed on the screw nut pair (3), and the lock nut (14) is used for positioning and tensioning, and the rotor of the encoder (15) is installed on the screw On the end shaft of the nut pair (3), the encoder (15) stator is fixed on the encoder box (12) by screws. The above steps have realized the transformation of the traditional motor, so tha...

Abstract

The invention belongs to the field of novel electric cylinder mechanical structure design, and especially relates to a structure which changes the transformation and connection mode of traditional motors and simplifies the connection mode between electric cylinder parts. Under the premise that the size of the electric cylinder is reduced, the coupling inside a traditional electric cylinder is removed. Through transformation of the motor part, the cost for motor purchase is saved. In addition, the mode of connection between most of the parts is simplified, screw connection between parts is canceled, the demand for position precision is met through the part structure, and a simpler and more compact electric cylinder internal structure and lower manufacture cost are achieved.

Description

technical field [0001] The invention belongs to the field of mechanical structure design of new electric cylinders, and in particular relates to a modification and connection method for changing traditional motors, and simplifies the connection method between parts of the electric cylinder. Background technique [0002] With the increase of application fields of electric cylinders, customers have higher and higher requirements for electric cylinders. Some industries hope to shorten the overall length of electric cylinders as much as possible when the performance of electric cylinders remains unchanged. In the case that the stroke of the electric cylinder remains unchanged, the overall length of the electric cylinder needs to be shortened. In this case, it is necessary to change the structure of the electric cylinder and its connection method. [0003] At present, there are two common ways to shorten the inherent length of the electric cylinder in the market: one is to use a...
