Abstract
Description
Technical Field
[0001] The utility model relates to a device for polishing defective welding points based on the stator winding of a servo motor. Background Art
[0002] Servo motors are core components in precision control, and their performance directly impacts the stability and reliability of the entire system. Stators typically come in either monolithic or spliced configurations. In monolithic stators, coil winding is performed manually through slots, requiring reshaping. This results in high coil ends, which is labor-intensive and time-consuming. Spliced stators, on the other hand, first require winding a single rack, then attaching end caps, rounding all the racks, and securing them with metal tie wraps. Finally, the tie wraps are removed, and the connections between each rack and the adjacent rack are welded.
[0003] After welding is completed, the welding points need to be polished. However, in the existing polishing process, an angle grinder is generally used for polishing. The angle grinder generates a large amount of dust during polishing. This dust not only pollutes the environment, but also may threaten the health of the operator. In view of this, the utility model proposes a bad welding point polishing device based on the stator winding of a servo motor to solve the above problem. Utility Model Content

[0008] As an improvement of the above technical solution, a mounting sleeve is rotatably provided on the outer wall of the exhaust pipe, and multiple groups of connecting pipes are arranged on the mounting sleeve. The mounting sleeve rotates about the axis of the exhaust pipe, so that the protective cover rotates outside the grinding disc.
[0009] As an improvement of the above technical solution, a limiting ring is fixedly provided on the outer wall of the exhaust pipe, a limiting groove is provided on the inner wall of the mounting sleeve, and the limiting ring is arranged in the limiting groove.

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Example:
[0028] like Figure 1-7 As shown, this embodiment proposes a device for grinding defective welds based on the stator winding of a servo motor, comprising an angle grinder 10, wherein the angle grinder 10 is provided with a grinding disc 13, and a mounting housing 11 is provided on the angle grinder 10;
[0029] The mounting shell 11 has a mounting portion 12, and an exhaust pipe 20 is provided on the mounting portion 12. The exhaust pipe 20 is coaxially arranged with the grinding disc 13. A protective cover 60 is provided on the mounting shell 11, and the grinding disc 13 is arranged in the protective cover 60. Multiple groups of connecting pipes 50 are provided between the exhaust pipe 20 and the protective cover 60. The connecting pipes 50 are connected to the inner cavity of the exhaust pipe 20, and the protective cover 60 is connected to the connecting pipes 50, so that dust is discharged through the connecting pipes 50 and the exhaust pipe 20 in sequence.
[0030] In this embodiment, when the angle grinder 10 is grinding a defective weld on the stator of a servo motor, the exhaust pipe 20 is connected to an external negative pressure device (such as a vacuum cleaner). The angle grinder 10 then performs the grinding process, and the generated dust enters the negative pressure device through the connecting pipe 50 and the exhaust pipe 20, completing the dust discharge process.
[0031] By providing a protective cover 60 and multiple groups of connecting pipes 50, not only is dust diffusion prevented, but the operator is also protected from being harmed by flying welding slag and metal particles, thereby improving the safety of operation, and effectively controlling and collecting the dust generated during the grinding process, thereby preventing the diffusion of dust and improving the working environment. At the same time, since the dust is promptly extracted from the grinding area, the impact of the dust on the grinding surface is reduced, thereby improving the quality of the weld after grinding.
[0032] Specifically, a mounting sleeve 40 is rotatably provided on the outer wall of the exhaust pipe 20 , and multiple groups of connecting pipes 50 are provided on the mounting sleeve 40 . The mounting sleeve 40 rotates about the axis of the exhaust pipe 20 , so that the protective cover 60 rotates outside the grinding disc 13 .
[0033] Specifically, a limiting ring 23 is fixedly provided on the outer wall of the exhaust pipe 20 , a limiting groove 42 is provided on the inner wall of the mounting sleeve 40 , and the limiting ring 23 is disposed in the limiting groove 42 .
[0034] In this embodiment, when the position of the protective cover 60 needs to be adjusted, it is only necessary to manually move the protective cover 60 so that the protective cover 60 and the mounting sleeve 40 rotate around the axis of the exhaust pipe 20, thereby completing the position adjustment of the protective cover 60, making it easier to polish the welding points at different positions of the servo motor stator.
[0035] Specifically, the outer wall of the exhaust pipe 20 is provided with multiple groups of connection holes 22, and the multiple groups of connection holes 22 are arranged in a ring array, and the multiple groups of connection holes 22 are arranged between the limiting ring 23 and the mounting portion 12;
[0036] The mounting sleeves 40 are disposed at a plurality of connection holes 22 , and the connection pipes 50 are communicated with the inner cavity of the air extraction pipe 20 through the connection holes 22 .
[0037] In this embodiment, when the dust is adsorbed, the negative pressure equipment tooling adsorbs the dust through the exhaust pipe 20, the connecting hole 22 and the connecting pipe 50;
[0038] Of course, since the connecting holes 22 are provided in a plurality of groups in a circular array, after the mounting sleeve 40 rotates, the connecting pipe 50 can always be connected to the connecting hole 22 to perform a normal adsorption process.
[0039] Specifically, the outer wall of the exhaust pipe 20 is provided with a threaded outer wall 21 , and a limit handle 30 is provided on the threaded outer wall 21 ;
[0040] The position limiting handle 30 defines a threaded hole 31 , and the threaded hole 31 is threadably engaged with the threaded outer wall 21 .
[0041] In this embodiment, the threaded hole 31 cooperates with the threaded outer wall 21 to facilitate the installation of the limiting handle 30 and facilitate the normal grinding process of the angle grinder 10.
[0042] Specifically, the limiting handle 30 is provided with a rubber part 32, and the surface of the mounting sleeve 40 is provided with multiple groups of anti-slip grooves 41. The limiting handle 30 rotates on the exhaust pipe 20, so that the rubber part 32 moves toward the mounting sleeve 40 and contacts the mounting sleeve 40 for limiting.
[0043] In this embodiment, when the limit handle 30 is connected to the exhaust pipe 20, the limit handle 30 is continuously rotated so that the limit handle 30 is displaced toward the mounting sleeve 40 until the rubber part 32 contacts the mounting sleeve 40, thereby rotating the mounting sleeve 40, so that after the position of the protective cover 60 is adjusted, the position of the protective cover 60 can be positioned.
[0044] Specifically, the protective cover 60 is fan-shaped, and the protective cover 60, the mounting sleeve 40, the grinding disc 13 and the exhaust pipe 20 are coaxially arranged.
[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
