Description

Technical Field

[0001] This utility model relates to the field of linear motor technology, and more specifically, to a permanent magnet vernier linear motor. Background Technology

[0002] A permanent magnet vernier linear motor is a special type of linear motor that combines permanent magnet excitation and the vernier effect. It achieves high thrust density and precise linear motion through harmonic magnetic field modulation between the stator and mover. An existing linear brushless DC motor, with publication number CN206023472U, is characterized by: a stator fixedly connected inside the motor, which is formed by a front cover and a rear cover; a hollow rotor assembly passing through the stator; a magnet assembly comprising a rotor core bonded to magnets; and a hollow shaft within the magnet assembly; bearings fitted at both ends of the hollow shaft, respectively mounted on the front and rear covers; a ball screw pair passing through the front cover and extending into the hollow shaft of the hollow rotor assembly, with the screw fixedly connected to the hollow shaft; an encoder disk fixedly connected to the screw; and the encoder fixedly mounted on the rear cover.

[0003] However, in the above structure, since the stator of the linear motor is exposed to the outside world, dust will be adsorbed on the upper surface and surrounding surface of the stator. The accumulation of dust may absorb moisture, which will reduce the insulation resistance of the stator winding and increase the risk of short circuit or leakage. Utility Model Content

[0004] The main purpose of this utility model is to provide a permanent magnet vernier linear motor that can effectively solve the problem in the background art where the stator of the linear motor is exposed to the outside world, causing dust to be adsorbed on the upper and surrounding surfaces of the stator. The accumulation of dust may absorb moisture, leading to a decrease in the insulation resistance of the stator windings and increasing the risk of short circuits or leakage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A permanent magnet vernier linear motor includes a slide block, a plurality of stators are provided at the bottom of the slide block, and sliding grooves are provided on both sides of the slide block. A sliding frame is slidably arranged in two of the sliding grooves, and a mover is provided on the lower surface of the sliding frame.

[0007] The bottom surface of the slide block is provided with several grooves, and the two sides of the inner wall of the slide block are provided with through slots. The two sides of the sliding frame are provided with cleaning components for cleaning dust from the bottom of the slide block.

[0008] Preferably, the cleaning component includes two air holes, both of which are opened through the corresponding side surface of the sliding frame, and threaded sleeves are fixedly installed on both sides of the sliding frame.

[0009] Preferably, each groove has a first connecting groove on both sides of its inner wall, and the slide has a second connecting groove on both sides of its inner wall. One end of each of the two second connecting grooves is connected to the corresponding first connecting groove.

[0010] Preferably, a baffle is fixedly installed at the bottom of each of the grooves.

[0011] Preferably, a sliding plate is slidably disposed in each of the two second connecting slots, and several dust-adhesive plates are fixedly installed on the opposite side of each of the two sliding plates. A connecting plate is fixedly installed on the side of each of the two sliding plates that is far apart from each other, and the two connecting plates are respectively fixedly installed on both sides of the slide block by bolts.

[0012] Preferably, several semi-circular plates are fixedly installed on both sides of the bottom of the slide block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When the sliding frame moves along the sliding groove, the air hole can move along the through groove. At this time, the staff can turn on the air supply equipment to let the gas enter the threaded sleeve through the hose, and then blow the upper surface and surrounding surface of the stator through the air hole, so that the dust enters the groove, thereby preventing the external dust from adsorbing on the upper surface and surrounding surface of the stator.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1-5 As shown, a permanent magnet vernier linear motor includes a slide 1, a plurality of stators 2 are provided at the bottom of the slide 1, and slide grooves 3 are provided on both sides of the slide 1. A sliding frame 4 is slidably arranged in the two slide grooves 3, and a mover 5 is provided on the lower surface of the sliding frame 4.

[0023] The slide block 1 has several grooves 6 on its inner bottom surface, and through grooves 7 are provided on both sides of the inner wall of the slide block 1. The sliding frame 4 is provided with cleaning components 8 on both sides for cleaning dust from the bottom of the slide block 1.

[0024] The cleaning component 8 includes two air holes 801, both of which are opened through the corresponding side surface of the sliding frame 4. Threaded sleeves 802 are fixedly installed on both sides of the sliding frame 4.

[0025] The staff connected the air supply equipment hose to the threaded sleeve 802, and then powered on the motor. With the cooperation of the stator 2 and the mover 5, the sliding frame 4 moved along the direction of the slide groove 3. When the sliding frame 4 moved along the direction of the slide groove 3, the air hole 801 could move along the direction of the through groove 7. At this time, the staff turned on the air supply equipment, so that the gas entered the threaded sleeve 802 through the hose, and then blew the upper surface and surrounding surface of the stator 2 through the air hole 801, so that the dust entered the groove 6, thereby preventing the external dust from adhering to the upper surface and surrounding surface of the stator 2.

[0026] In another embodiment of the present invention, a first connecting groove 9 is provided on both sides of the inner wall of each groove 6, and a second connecting groove 10 is provided on both sides of the slide block 1. One end of each of the two second connecting grooves 10 is connected to the corresponding first connecting groove 9.

[0027] Each groove 6 has a baffle 11 fixedly installed at the bottom.

[0028] Slide plates 1101 are slidably installed in both second connecting slots 10. Several dust-adhesive plates 12 are fixedly installed on the opposite side of the two slide plates 1101. Connecting plates 13 are fixedly installed on the opposite side of the two slide plates 1101. The two connecting plates 13 are fixedly installed on both sides of the slide block 1 by bolts 14.

[0029] After the dust enters the groove 6, it falls onto the surface of the dust-adhesive plate 12. Then, the staff removes the bolt 14 and pulls the connecting plate 13 to move the baffle 11, making it easier for the staff to disassemble the dust-adhesive plate 12 for subsequent cleaning.

[0030] In another embodiment of this utility model, several semi-circular plates 15 are fixedly installed on both sides of the bottom of the slide block 1.

[0031] By setting the semi-circular plate 15, dust can move into the groove 6 through the arc surface of the semi-circular plate 15, preventing dust from sticking to both sides of the stator 2 after being blown by the gas, thus improving the cleaning effect.

[0032] The working principle of this permanent magnet vernier linear motor:

[0033] In use, the operator connects the air supply hose to the threaded sleeve 802, and then powers on the motor. With the cooperation of the stator 2 and the mover 5, the sliding frame 4 moves along the direction of the slide groove 3. When the sliding frame 4 moves along the direction of the slide groove 3, the air hole 801 can move along the direction of the through groove 7. At this time, the operator turns on the air supply equipment, so that the gas enters the threaded sleeve 802 through the hose, and then blows the upper surface and surrounding surface of the stator 2 through the air hole 801, so that the dust enters the groove 6, thereby preventing external dust from adhering to the upper surface and surrounding surface of the stator 2.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
