Description

Technical Field:

[0002] The present invention relates to the field of motor production, and in particular to an auxiliary pasting device for insulating paper at the motor terminal. Background Art:

[0004] A generator (English name: Generators) is a mechanical device that converts other forms of energy into electrical energy. A generator mainly consists of components such as a stator, a rotor, an end cover, brushes, a machine base, and bearings. The stator is composed of a machine base, a stator core, a wire winding, and other structural components that fix these parts. The rotor is composed of a rotor core, rotor magnetic poles (with a magnetic yoke and pole windings), slip rings (also known as copper rings and collector rings), a fan, and a rotating shaft, etc.; through bearings, a machine base, and an end cover, the stator and rotor of the generator are connected and assembled, enabling the rotor to rotate in the stator. By passing a certain exciting current through the slip rings, the rotor becomes a rotating magnetic field, and the stator coils make a movement of cutting the magnetic force lines, thereby generating an induced electromotive force, which is led out through the terminal and connected in a circuit to generate current.

[0005] In actual work, different phase wires inside the motor and the motor housing are in an insulated state from each other. Their insulation is carried out through insulating paint. However, at the end lead wire part, since it needs to be connected to the wire, this part is often exposed outside. During use, this part is extremely likely to come into contact with the motor housing, causing the motor housing to be electrified and affecting production safety. The existing method is to paste insulating paper on the motor housing at the corresponding part to block the contact between the connection part and the motor housing, thereby ensuring the safe operation of the motor.

[0006] In the prior art, a movable mold is used to assist in installing the insulating paper. When in use, first place the movable mold on the motor housing, and then place the cut insulating paper in the groove on the movable mold for auxiliary pasting. Since the groove is a straight-through groove, when placing the insulating paper in it, personnel need to hold the insulating paper by hand and maintain a certain height, and the other hand reaches into the movable mold and the motor housing to paste the insulating paper. This operation method often causes the position and size of the insulating paper pasted on the motor housing to be inconsistent, which is not convenient for subsequent processing and production. Summary of the Invention:

[0008] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art. Through the connection between a base, a fixing device, a cylinder, and a limiting device, relying on the cylinder to drive the limiting device to move on the fixing device, the fixing of the motor housing placed on the fixing device is realized. At the same time, the fixing device is provided with a groove, which is convenient for placing the insulating paper, improves work efficiency, and solves the problem that the position and size of the insulating paper pasted in the prior art are inconsistent. An auxiliary pasting device for insulating paper at the motor terminal.

The cylinder is arranged in the storage cavity, and its piston rod passes through the baffle at the top and is connected to the limiting device;

[0011] The fixing device includes an upper fixing block, a lower fixing block and a connecting rod. The upper fixing block and the lower fixing block are connected by the connecting rod. The lower fixing block is fixed on the baffle at the top of the frame through a clamping block. A first through hole for the piston rod to pass through is arranged on the lower fixing block, and a second through hole coaxial with the first through hole and for the limiting device to pass through is arranged on the upper fixing block;

[0012] The limiting device is a limiting block in the shape of an uncovered cylindrical barrel. One end of the limiting block passes through the second through hole and is connected to the piston rod, and two grooves are symmetrically arranged at the other end of the limiting block.

[0013] Further, two symmetrical planes are arranged on the limiting block, and the two planes and the two grooves are alternately and evenly distributed on the limiting block.

[0014] Further, positioning beads with the same height are arranged on the plane.

[0015] Further, the clamping block is in an L-shaped structure and is fixed on the baffle through bolts. The upper fixing block is provided with a limiting groove for the motor housing to be placed, and the limiting groove is coaxial with the second through hole.

[0017] Further, pulleys are arranged at the bottom of the frame.

[0018] The beneficial effects of the present invention are:

[0019] 1.

[0020] 2. On the other end of the limit block of the present invention, there are two symmetrically arranged grooves. The insulating paper can be directly placed in the grooves. Due to the support of the limit block, the insulating paper will not fall off, solving the problem of always having to hold the insulating paper by hand. One only needs to reach into the grooves to paste the insulating paper.

[0021] 3. The baffle of the present invention surrounds the four sides and the top of the frame, supporting the fixing device and the limiting device while making its interior a storage cavity.
