[0029] The specific settings and functions of the adjustment structure 4 and the torsion structure 5 are described in detail below.
[0030] Reference Figure 1-Figure 3 As shown, in this embodiment: the adjustment structure 4 includes a plurality of slide grooves 410 provided on the surface of the limit plate 2, the inner wall of the slide groove 410 is slidably connected with a slider 401, the interior of the slider 401 is rotatably connected with a turn pin 411, and the end side of the turn pin 411 is fixedly connected with the grinding head 3. By setting the adjustment structure 4, it is convenient to expand or contract a plurality of grinding heads 3 at the same time, and it is convenient to use a single working head to polish and grind the outer surface or inner side of motor coils of different sizes, which improves the use efficiency of the working head to a certain extent. The outer side of the mounting cylinder 1 is provided with an external thread 403, and the surface of the external thread 403 is threadedly connected with a drive head 402, and the drive head 402 is a truncated cone structure. By rotating the drive head 402 on the outer surface of the external thread 403, the drive head 402 can push a plurality of sliders 401 to slide on the inner side of the slide groove 410 at the same time.
[0031] The side wall of the mounting tube 1 is fixedly connected with a second connecting strip 409, and a sliding rod 408 is slidably connected inside the second connecting strip 409. The end surface of the sliding rod 408 is fixedly connected with a pressing ring 405, and the side wall of the slider 401 is fixedly connected with an inclined plate 404. The sliding of the sliding rod 408 inside the second connecting strip 409 plays a role in limiting the moving direction of the pressing ring 405, and the pressing ring 405 can realize the simultaneous extrusion of multiple inclined plates 404. The side wall of the mounting tube 1 is fixedly connected with a first connecting strip 406, and the internal thread of the first connecting strip 406 is connected with a screw 407, and the screw 407 is rotatably connected to the inside of the pressing ring 405. When the screw 407 inside the first connecting strip 406 is rotated, the screw 407 will push the pressing ring 405 to move.
[0032] Reference Figure 1 and Figure 3-Figure 4 As shown, specifically, the torsion structure 5 includes a fixing bar 53 fixedly connected to the outer surface of the slider 401, the fixing bar 53 is slidably connected to the insert frame 51, and the side wall of the rotating pin 411 is evenly provided with a plurality of slots 52, and the size of the slots 52 is adapted to the size of the insert frame 51. By rotating the rotating pin 411 and the grinding head 3 inside the slider 401, the use surface of the grinding head 3 can be adjusted.
[0033] The insert frame 51 is a rectangular ring structure, and an elastic rope 54 is fixedly connected to the side where the insert frame 51 and the fixing bar 53 are close to each other. The insert frame 51 is pulled by the elastic rope 54 to be inserted into the inner side of the slot 52. Two protrusions 55 are fixedly connected to the side wall of the insert frame 51, and the protrusions 55 are made of rubber. The setting of the rubber protrusions 55 increases the friction when the hand pulls the insert frame 51, which facilitates the pulling of the insert frame 51.
[0034] Working principle: when it is necessary to grind motor coils of different sizes, when it is necessary to grind the inner side of the motor coil, first put the motor coil on the inner side of several grinding heads 3, then the driving head 402 on the outer surface of the external thread 403 can be rotated, and the driving head 402 can push multiple sliders 401 to slide on the inner side of the slide groove 410 at the same time. When the grinding head 3 moves to a position close to the inner side of the motor coil, the polishing and grinding work on the inner side of the motor coil can be achieved. When it is necessary to polish the outer surface of the motor coil, the screw 407 inside the first connecting strip 406 can be rotated, and the screw 407 will push the pressure ring 405 to move, and the slide rod 408 slides inside the second connecting strip 409. The movement plays a role in limiting the moving direction of the pressure ring 405. The pressure ring 405 can realize the simultaneous extrusion of multiple inclined plates 404, thereby realizing the simultaneous approaching driving of multiple sliders 401. The motor coil is placed on the inner side of the circular array driving head 402, so as to realize the polishing and grinding of the outer surface of the motor coil. By setting the end side of the grinding head 3 as a truncated cone structure, the grinding work of the chamfer position of the motor coil is facilitated. By setting the adjustment structure 4, the simultaneous expansion or contraction of several grinding heads 3 is facilitated, and the use of a single working head is convenient for polishing and grinding the outer surface or inner side of motor coils of different sizes, thereby improving the use efficiency of the working head to a certain extent.
[0035] The insertion frame 51 inside the pulling fixing bar 53 and the setting of the rubber material protrusion 55 increase the friction when the hand pulls the insertion frame 51, which facilitates the pulling of the insertion frame 51. After the insertion frame 51 is pulled out from the inner side of the slot 52, the rotation pin 411 inside the slider 401 and the grinding head 3 can be rotated. At this time, the use surface of the grinding head 3 can be adjusted, avoiding the situation that the grinding head 3 is easily increased due to long-term use of one side. After the grinding head 3 is rotated to a suitable position, the insertion frame 51 can be loosened. At this time, the insertion frame 51 will be inserted into the inner side of the slot 52 under the pulling force of the elastic rope 54, so that the fixing work of the twisted grinding head 3 can be achieved. By setting the torsion structure 5, the use of different surfaces of the grinding head 3 is facilitated, and the utilization rate of the outer surface of the grinding head 3 is improved.
