Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a wiring fixture for enameled wire in motors. Background Technology

[0002] Electric motors, as power sources driving various equipment and machinery, are widely used in industries such as industry, transportation, home appliances, and automation control. During the motor manufacturing process, enameled wire (materials include but are not limited to copper wire, copper-clad aluminum wire, aluminum wire, etc.) is wound or embedded into the stator slots using equipment. The integrity of the enameled wire coating and the amount of enameled wire used directly affect the motor's operational stability and performance.

[0003] During the motor manufacturing process, the enameled wire on the spool is quickly pulled out and wound up using a special winding machine. During the pulling process, due to centrifugal force, the enameled wire may sling out, posing a risk of scratching the surrounding tooling. In addition, if the enameled wire spool is not replaced in time after the enameled wire is completely pulled out from the spool, it will result in insufficient enameled wire for the motor, affecting the motor's performance.

[0004] In view of the problems existing in the prior art, it is necessary to study and design a new type of wiring fixture for enameled wires in motors, so as to overcome the problems existing in the prior art. Summary of the Invention

[0005] In response to the technical problems mentioned above in the prior art, such as the wire throwing phenomenon caused by centrifugal force during the wire extraction process, which poses a risk of scratching the surrounding tooling, and the insufficient amount of enameled wire used in the motor if the wire spool is not replaced in time after the enameled wire is completely extracted from the spool, thus affecting the performance of the motor, this paper provides a wire routing tool for motors.

[0006] The technical means adopted in this utility model are as follows: A wiring fixture for enameled wire in an electric motor includes: a nut, a threaded sleeve, a ceramic eye, an L-shaped bracket, a right-angle bracket, a mounting plate, a middle slot ceramic eye, a slot positioning clamp, and a bowl shape; Furthermore, the central groove ceramic eye is fixedly mounted to the center of the upper end of the bowl shape by a groove positioning clamp; Furthermore, the L-shaped bracket is inverted and fixed to the upper end of the bowl shape; Furthermore, the right-angle bracket is fixedly mounted to the middle of the L-shaped bracket via a mounting plate; Furthermore, the threaded sleeve is installed on the top of the L-shaped bracket via a threaded fit; Furthermore, the ceramic eye is placed inside the threaded sleeve; Furthermore, a nut is fitted to the top of the threaded sleeve via a threaded connection.

[0007] Furthermore, a conical hole is provided at the bottom of the bowl shape, and the center of the conical hole coincides with the center of the bowl shape.

[0008] Furthermore, the central groove ceramic eye is wrapped by two groove positioning clamps with identical structures; Furthermore, the two slot positioning clamps are fixed to the top of the bowl shape with bolts; Furthermore, the center of the inner hole of the ceramic eye in the middle groove is installed in alignment with the center of the conical hole.

[0009] Furthermore, the bottom of the L-shaped bracket is provided with bolt holes, and it is fixedly connected to the bowl-shaped bracket by bolts; Furthermore, the L-shaped bracket has a slot in the middle, into which the mounting plate is horizontally inserted and fixed with bolts.

[0010] Furthermore, the mounting plate is provided with through holes for the enameled wire to pass through. The through holes are required to have a high degree of smoothness to avoid scratching the enamel film of the enameled wire when it passes through. Furthermore, ceramic eyelets can be added to the through holes to protect them from damage to the paint film; Furthermore, bolt holes are provided on the mounting plate, and the right-angle bracket is fixedly mounted on it by bolts.

[0011] Furthermore, the right-angle bracket is machined with a reserved connection port for installing a proximity switch. When the enameled wire is missing, the equipment alarms, promptly reminding the operator to perform a wire replacement operation.

[0012] Furthermore, both ends of the threaded sleeve are designed with threads for threaded connection with the L-shaped bracket and the nut, respectively; Furthermore, the threaded sleeve has an axial through hole machined inside for the enameled wire to pass through.

[0013] Furthermore, the ceramic eye is installed in the lower groove of the threaded sleeve, with one end of the ceramic eye contacting the threaded sleeve. A matching resin tube is inserted into the threaded sleeve and contacts the other end of the ceramic eye, located in the middle of the threaded sleeve and the L-shaped bracket. When the threaded sleeve is threadedly tightened with the nut 1, the resin tube and the ceramic eye 3 can be fixed and clamped simultaneously. Furthermore, the ceramic eye and the middle groove ceramic eye are made of ceramic, with a high degree of smoothness in the inner hole. The center lines of the bowl-shaped conical hole, the inner hole of the middle groove ceramic eye, the through hole of the mounting plate, the inner hole of the ceramic eye, the axial through hole of the threaded sleeve, and the nut tend to be on the same line, which helps to reduce the resistance when the enameled wire passes through and reduces the risk of damage to the enameled wire coating.

[0014] The enameled wire routing device is placed at the wire outlet at the top of the spool or drum. The enameled wire passes sequentially through a bowl-shaped tube, a central slot ceramic eye, a mounting plate, a proximity switch, and another ceramic eye before entering a resin tube that contacts the ceramic eye and finally reaching the designated winding equipment. Since the central slot ceramic eye and the enameled wire are in direct contact and friction for a long time, it is necessary to regularly inspect and confirm the central slot ceramic eye and its inner surface. If the inner surface is found to be rough, it needs to be replaced or polished for maintenance.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The wiring fixture for enameled wires for motors provided by this utility model realizes the transition of motor enameled wires from the spool to the winding equipment, which can effectively avoid the wire damage caused by the wire throwing phenomenon due to centrifugal force when the enameled wire is pulled off the spool; 2. The motor enameled wire routing fixture provided by this utility model can be equipped with a proximity switch at the right-angle bracket to detect whether enameled wire is passing through. If there is no wire, the switch will be triggered to alarm and remind the user to replace the wire spool in time, so as to avoid motor performance problems caused by failure to detect insufficient enameled wire in time. 3. The wiring fixture for enameled wire in motors provided by this utility model ensures the quality of motor production.

[0016] In summary, the technical solution of this utility model solves the problems in the prior art where, during the extraction of enameled wire, the wire is thrown off due to centrifugal force, posing a risk of scratching the surrounding tooling; and where, if the wire spool is not replaced in time after the wire is completely extracted from the spool, insufficient enameled wire is used in the motor, affecting the motor's performance.
