Description

Technical Field

[0001] The utility model relates to the technical field of motor manufacturing, in particular to an auxiliary assembly tool for a claw-pole motor end cover. Background Art

[0002] Claw-pole motors generally include a rotor, a stator, and a housing. Figure 1 Two claw poles 10 are installed on the rotating shaft 9 (as shown in the figure), and the two claw poles 10 each have six bird's beak-shaped magnetic poles and are installed alternately up and down. A claw pole groove 11 is formed between the upper and lower bird's beak-shaped magnetic poles, and a bearing 12 is installed above the two claw poles 10.

[0003] In current motor assembly, when installing the housing end cover, the mounting hole on the end cover is used to clamp the rotor bearing, and then the nut is fixed to the threaded section on the shaft. When the nut is tightened, the shaft is subjected to force and rotates, making the nut installation more difficult. The operator needs to manually hold the claw pole to prevent the shaft from rotating, which is physically demanding and has poor stability, affecting assembly efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a claw-pole motor end cover auxiliary assembly tool, which can position the rotor as a whole when the rotor end cover nut is installed, avoid the shaft being rotated by force when the nut is tightened, facilitate the installation of the nut, do not require human support, and improve assembly efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an auxiliary assembly tool for the claw-pole motor end cover, comprising a table, on which a rotor placement tube is fixedly provided through a limit piece, the inner diameter of the rotor placement tube is adapted to the outer diameter of the rotor, and a screw hole is provided on the tube wall of the rotor placement tube, and an anti-rotation clamping rod is threadedly connected to the inner thread of the screw hole, and the diameter of the anti-rotation clamping rod is adapted to the slot width of the claw pole slot of the rotor.

[0006] A further improvement of the utility model is that the limit member includes a movable clamping block and a fixed clamping block relatively arranged on the table plate, a power source for driving the movable clamping block to move is provided on the side of the movable clamping block away from the fixed clamping block, and the rotor placement tube is clamped between the movable clamping block and the fixed clamping block.

[0007] A further improvement of the utility model is that an auxiliary clamping rod is threadedly connected to the fixed clamping block, a plug hole is provided on the tube wall of the rotor placement tube, and one end of the auxiliary clamping rod passes through the fixed clamping block and is inserted into the plug hole.

[0008] A further improvement of the utility model is that V-shaped openings are provided on the opposite sides of the fixed clamping block and the movable clamping block, and the rotor placement tube is clamped between the two V-shaped openings.

[0009] A further improvement of the utility model is that the height of the rotor placement tube is lower than the height of the rotor.

[0010] A further improvement of the utility model is that the power source is a cylinder, the cylinder is arranged on the table and the telescopic end thereof is fixedly connected to the movable clamp block.

[0011] A further improved solution of the present invention is that the anti-rotation clamping rod is located above the auxiliary clamping rod.

[0012] The beneficial effects of the utility model are:

[0013] The utility model provides a rotor placement tube that cooperates with the anti-rotation clamping rod, utilizes the rotor structure of the claw-pole motor, and limits the claw pole slots of the rotor through the anti-rotation clamping rod, so that the rotor as a whole can be positioned when the end cover nut of the rotor is installed, avoiding the shaft from being forced to rotate when the nut is tightened, facilitating the installation of the nut, eliminating the need for human support, and improving assembly efficiency.

[0014] The utility model can select rotor placement tubes with different diameters according to different rotor diameters by arranging the dynamic clamping block and the fixed clamping block, can effectively clamp and fix the rotor placement tube through the V-shaped opening, has good positioning effect and wide application range.

[0015] The utility model can avoid the situation that the rotor placement tube rotates as a whole when the nut is tightened due to loose clamping by arranging the auxiliary clamping rod, and the rotation thereof is restricted by the auxiliary clamping rod, thereby further improving the stability during assembly.

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Example 1: Combination Figure 1~2It can be seen that an auxiliary assembly tool for the claw-pole motor end cover includes a table plate 1, on which a rotor placement tube 2 is fixedly provided through a limit piece, the inner diameter of the rotor placement tube 2 is adapted to the outer diameter of the rotor, a screw hole is provided on the tube wall of the rotor placement tube 2, an anti-rotation clamping rod 3 is threadedly connected to the inner thread of the screw hole, and the diameter of the anti-rotation clamping rod 3 is adapted to the slot width of the claw pole slot of the rotor.

[0021] The limiting member includes a movable clamping block 4 and a fixed clamping block 5 which are relatively arranged on the table 1. A power source 6 for driving the movable clamping block 4 to move is provided on the side away from the fixed clamping block 5. The rotor placement tube 2 is clamped between the movable clamping block 4 and the fixed clamping block 5.

[0022] The fixed clamp block 5 is threadedly connected with an auxiliary clamp rod 7, and a plug hole is provided on the wall of the rotor placement tube 2. One end of the auxiliary clamp rod 7 passes through the fixed clamp block 5 and is inserted into the plug hole. One end of the auxiliary clamp rod 7 is located in the plug hole and does not contact the rotor, and the other end is provided with a handle for easy adjustment.

[0023] V-shaped openings 8 are provided on the opposite sides of the fixed clamping block 5 and the movable clamping block 4 , and the rotor placement tube 2 is clamped between the two V-shaped openings 8 .

[0024] The height of the rotor placement tube 2 is lower than the height of the rotor. When the rotor is placed in the rotor placement tube 2, its upper end is exposed so that the end cover can be installed.

[0025] The power source 6 is a cylinder, which is arranged on the table 1 and whose telescopic end is fixedly connected to the movable clamp block 4. The power source 6 can also be an electric telescopic rod or a hydraulic rod.

[0026] The anti-rotation clamp rod 3 is located above the auxiliary clamp rod 7. The anti-rotation clamp rod 3 is arranged at a relatively upper position on the rotor placement tube 2, so that the rotor can be better positioned when the nut is driven.

[0027] The working principle of the claw-pole motor end cover auxiliary assembly tool provided by the utility model is as follows: when in use, the rotor placement tube 2 is placed between the dynamic clamping block 4 and the fixed clamping block 5, and the cylinder is started to make the dynamic clamping block 4 move and cooperate with the fixed clamping block 5 to clamp and fix the rotor placement tube 2, and the rotor is placed in the rotor placement tube 2. The rotor is restricted by the rotor placement tube 2 to keep the rotating shaft vertical, and the rotor is rotated in the rotor placement tube 2 to adjust its angle so that the claw pole groove of the rotor is aligned with the screw hole, and the anti-rotation clamping rod 3 is deeply inserted into the claw pole groove to realize the positioning of the rotor. When the nut is installed later, the rotating shaft can be effectively prevented from being rotated under force, and the positioning can be effectively maintained to improve the installation efficiency of the nut.
