Bending device and method for long stator cable winding end of linear motor

Abstract

The invention discloses a device for bending the end of a long stator cable winding of a linear motor and a method thereof. The device comprises: a straight side fixing part, an end bending part and a driving mechanism; The straight side limit structure of the straight side of the part; the curved part of the end includes: a static receiving part and a curved part that can move relative to the static receiving part; the static receiving part and the fixed part of the straight side are relatively fixed; The static receiving part is provided with a receiving surface for matching the shape of the end of the bending part; the moving bending part is provided with a bending surface for matching the shape of the end of the bending part; the driving mechanism can drive the moving bending part Move towards the static receiving part until the limit stop structure of the curved part is triggered to stop the movement of the curved part, thereby realizing the bending of the end of the long stator cable winding of the linear motor. This scheme is easy to operate, small in size and low in cost, so as to meet the requirement of bending the end of the cable winding.

Description

technical field [0001] The invention relates to the technical field of linear motors, in particular to a device and a method for bending end portions of long stator cable windings of linear motors. Background technique [0002] The three-phase windings of the long stator of a certain linear motor are all 300mm 2 A single cable is repeatedly bent and shaped, and its main structural shape is shown in Figure 4 shown. This kind of cable winding needs to be bent and formed through two steps of primary bending and secondary end bending. First, a single cable is repeatedly bent into a continuous two-dimensional plane U shape through a specific device, such as image 3 shown; then, the end of the cable winding that has been bent to a two-dimensional plane U-shape is bent separately by using a specific device, as shown in Figure 4 The shape of the structure shown. [0003] At present, Germany uses wiring equipment (electric and pneumatic devices) to realize the bending of cable ...

AI Technical Summary

Problems solved by technology

[0004] At present, the structure of the wiring equipment imported from Germany is relatively complicated; the price of the equipment is more than 10 million, and the price is relatively expensive; the cable bending operation site is in the wild, and the equipment is large in size, which is inconvenient for equipment transportation and movement, and is not convenient for operation
