Description

Multipurpose flat shovel for repairing broken wire of motor coil

Technical Field

The utility model relates to a repair electric machine instrument, in particular to repair multi-purpose flat shovel of motor coil broken string.

Background

The coils of the stator of the electrical machine are wound in stator slots, a plurality of which are distributed along the circumference of the stator. Therefore, the stator coil is wound on the stator slot, and the coil ends of the closed enameled wire are exposed out of two ends of the stator for a certain length. When a motor stator coil is repaired, a flat shovel is used for shoveling a winding coil at one end of a stator, a punch is used for punching off an enameled coil in a stator slot, and then the enameled coil is pulled out. Because the ordinary flat shovel is that the shovel head and the handle are on the same straight line, but the motor stator slot is the recess of taking the arc, therefore when the shovel coil is disconnected, not only hard, but also easily produce stator slot shell silicon steel sheet and go bad, influence the motor magnetic flux, the motor is consequently burnt out frequently. Nowadays, the flat shovel that electric tool used is hexagonal or four-edged, and the electric pick uses hexagonal flat shovel, and the electric hammer uses four-edged flat shovel, all has a definite to used flat shovel model, and the two is difficult for manual work to use, consequently, operating personnel often need purchase the flat shovel of multiple model and just can the operation.

To some small-size motors, need not to use electric tool, use the manual coil of shoveling of flat shovel labour saving and time saving more, and current flat shovel does not consider the use comfort level under the manual condition for manual shovel line is extraordinarily hard.

SUMMERY OF THE UTILITY MODEL

In view of this, provide one kind and repair the motor coil broken string multi-purpose flat shovel. The flat shovel can avoid damaging the stator slot shell when in use, and saves time and labor.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

1. the utility model is used for the motor is disassembled in the maintenance, can be when tearing open the coil the whole concave yield stator inslot all of shovel head, and its handle help user of service changes when using in having an effect, and the parallel atress of shovel head can the non-resistance broken string, and it is laborsaving to save labour.

2. The utility model discloses but the quadrangular external electric hammer that the tip was established, but the hexagonal prism of establishing external electric pick to the purpose of high-efficient work more.

3. The utility model discloses the single-blade arc recess that shovel head established, when shovel head cut off the coil, the arc sword had both regarded as the sword body, regarded as the bayonet socket again, had excellent positioning action, avoided running about the coil.

4. The utility model discloses when the operation in-process and drop carelessly, the arc sword indent can make the sword body obtain the protection, prevents that the sword body from leading to the fact blunting, sword that rolls up because of the collision with the impact that drops.

5. Through having add manual lag, in manual shovel line in-process labour saving and time saving, the staff degree of adaptability is better, the operation of being convenient for.
