Technical Field

The invention relates to the technical field of motor assembling devices, in particular to combined slot cover paper for a rotor.

Background

The stator and the rotor are important components of the motor, because of different types of motors, rotors with different structures exist, some rotors are formed by silicon steel sheets in a laminated mode and are formed in an aluminum casting mode, some rotors are formed by laminating and are wound with enameled wires, and then the outer ring of the rotor needs to be provided with a wire groove, the enameled wires can be arranged in the wire groove, and insulating slot cover paper needs to be inserted into the groove opening on the outer side of the enameled wires; meanwhile, the slot cover paper is generally pushed into the rotor by using a push pin, because the slot cover paper is thin, the push pin acts on the side edge of the slot cover paper, a slot opening is easily punched on the side wall of the slot cover paper, the slot opening can affect insulation isolation, and further the electrical performance of the motor can be affected; therefore, in the final detection process, the cover paper of the groove needs to be replaced, and the workload of rework is increased.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides combined slot cover paper for a rotor.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

the utility model provides a combination formula slot lid paper for rotor, includes upper cover plate and lower cover plate, and the both sides shaping of upper cover plate upwards inclines last fender piece, and lower cover plate is fixed on the lower terminal surface of upper cover plate, and the both sides shaping of lower cover plate has the lower fender piece of downward sloping, and the front end shaping of lower cover plate has the U type guide vane of forward extension, and the other end of U type guide vane is pasted and is fixed on the up end of upper cover plate.

Preferably, the thickness of the upper cover sheet is equal to the thickness of the lower cover sheet, and the length and width of the upper cover sheet are respectively equal to the length and width of the lower cover sheet.

Preferably, the width of the upper blocking piece on the upper cover plate is larger than that of the lower blocking piece on the lower cover plate, and the side wall of the upper cover plate is flush with that of the lower cover plate.

Preferably, the width of the upper baffle plate on the upper cover plate is 4-5 times that of the lower baffle plate on the lower cover plate.

Preferably, the corner of the upper blocking piece on the upper cover piece or the corner of the lower blocking piece on the lower cover piece is respectively formed with a first round angle and a second round angle.

Preferably, the included angle between the upper blocking piece and the upper cover piece is equal to the included angle between the lower blocking piece and the lower cover piece.

Preferably, a catching groove is formed on the upper cover plate at the rear side of the U-shaped guide sheet.

The invention has the beneficial effects that:

(1) the slot cover paper of its adoption comprises two-layer scraps of paper, and the slot cover paper can the elasticity centre gripping in the wire casing of rotor, has strengthened the intensity of slot cover paper simultaneously, appears the cracked situation of slot cover paper side when can reducing mounting groove cover paper to can alleviate the work load of doing over again.

(2) The arc-shaped guide piece is arranged on the slot cover paper, so that the outer paint layer of the enameled wire can be prevented from being stripped in the installation process of the slot cover paper.
