Description

Technical Field

[0001] This utility model relates to a shearing device, and more particularly to a shearing device for stator leads of an automotive motor. Background Technology

[0002] As is well known, automotive motors consist of a stator and a rotor. The stator comprises an iron core and coil windings wound around the iron core. After the coil windings are installed, three or four leads are led out from one end of the iron core for easy connection to electricity. To improve product quality, the ends of the leads need to be cut to ensure that the lengths of the multiple leads are consistent.

[0003] Currently, the stator lead wires are mostly cut manually, which involves measuring and marking each wire end with a steel ruler and then cutting them one by one with pliers. This method not only has low processing precision and low production efficiency, but also produces sharp cuts that can easily scratch fingers during subsequent processing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cutting device for stator leads of automotive motors with high processing accuracy and production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stator lead wire cutting device for an automotive motor includes a base, a slide rail fixed vertically on the base, a cutting plate fixed on one side of the groove of the slide rail, and multiple wire-passing holes on the cutting plate for inserting the lead wire to be cut; a cutting blade is provided in the groove of the slide rail through a sliding gap for cooperating with the cutting plate to cut the lead wire. A linear power source is supported by a seat plate at the upper end of the slide. The output end of the linear power source is connected to the shearing blade through a connector to drive the shearing blade to reciprocate. A pressure plate is provided on the side of the slide groove away from the shearing plate, and an elastic pressure member is provided on the slide. The inner end of the elastic pressure member presses against the pressure plate, so that the shearing blade is tightly attached to the shearing plate.

[0006] As a further preferred embodiment, the shearing blade includes a shearing blade body, the lower end of which is V-shaped, and an alloy blade head is provided on the side of the lower end of the shearing blade body corresponding to the shearing plate.

[0007] As a further preferred embodiment, a stepped groove is provided at the upper end of the shearing blade body, and the connecting member is screw-shaped, with its lower end being the large end and being locked in the groove, and its upper end being connected to the output end of the linear power source by a thread.

[0008] As a further preferred option, the linear power source is a drive cylinder.

[0009] As a further preferred embodiment, a rectangular groove is provided at the bottom of the groove on the slide rail, and the pressure plate is provided in the rectangular groove through a clearance fit.

[0010] As a further preferred embodiment, the elastic pressure member includes an adjusting stud, one end of which is threaded into a threaded hole located on the slide rail, and a blind hole is provided at the inner end of the adjusting stud and a pressure spring is inserted therein, with the outer end of the pressure spring abutting against the pressure plate.

[0011] As a further preferred option, a V-shaped support is fixed on the base on one side of the shearing plate, and two baffles are symmetrically fixed on the V-shaped support near the shearing plate end to position the automotive motor stator to be sheared, thereby improving processing accuracy.

[0012] The beneficial effects of this utility model are as follows: 1. The inner end of the elastic pressure member presses against the pressure plate, so that the shearing blade is tightly attached to the shearing plate. The shearing blade is driven to reciprocate by a linear power source, which can cut multiple automotive motor stator leads that pass through the wire holes and shearing plate in one go. This not only has high processing accuracy and high production efficiency, but also produces a neat cut, which is convenient for subsequent processing.

[0013] 2. Because a V-shaped support is fixed on the base on one side of the shearing plate, and two baffles are symmetrically fixed on the V-shaped support near the shearing plate, the stator of the automobile motor to be sheared can be positioned, so that the length of the lead wires after shearing is consistent, and the processing accuracy is further improved.
