DETAILED DESCRIPTION

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the preferred embodiments of the present invention, rather than all the embodiments. It should be understood by those skilled in the art that these implementation methods are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1-4 ;

[0024] The utility model provides the following technical solutions: a stator dust removal device, used for cleaning dust, iron filings and other pollutants from the iron core of a stator 12, comprising a pair of support rollers 11 fixedly arranged on a base 1 for supporting the circumferential side of the stator 12; one of the support rollers 11 is connected to a motor, the motor is fixedly connected to the base 1, and is used for the stator 12 to rotate; it also includes a hollow tube 2 coaxially arranged with the stator 12; at least one pair of connecting rods hinged in the middle, namely a first connecting rod 21 and a second connecting rod 22; one end of the first connecting rod 21 is hinged to the end of the hollow tube 2, and the other end thereof is hinged to one end of the blowing pipe 3; one end of the second connecting rod 22 is hinged to a slider 4 slidably connected to ... A sliding sleeve 5, one end of which is hinged on a sliding sleeve on the blowing pipe 3, is used to drive the blowing pipe 3 away from or close to the hollow pipe 2 when the slider 4 translates along the hollow pipe 2; the slider 4 is connected to a driving mechanism for driving the slider 4 to translate; one end of the blowing pipe 3 is connected to a hose 31 for inputting high-pressure gas into the blowing pipe 3; the other end of the blowing pipe 3 can be inserted into the winding groove 15 of the stator 12, and a plurality of air outlet holes 32 are provided on its side wall; the base 1 is slidably connected to the bottom plate 7, and an electric push rod 13 is fixed on the bottom plate 7. The end of the electric push rod 13 is connected to the base 1, and is used to drive the stator 12 to translate, so that the blowing pipe 3 is inserted into the winding groove 15.

[0025] The working principle includes that the servo motor 16 is used to control the rotation angle of the stator 12, so that after the stator 12 is rotated, the air blowing pipe 3 can still be inserted into the winding groove 15. The hollow tube 2 is the installation base of the air blowing pipe 3. The radial position of the air blowing pipe 3 can be adjusted through the connecting rod hinged in the middle, so that it can adapt to stators 12 of different diameters and improve adaptability. Connected by a hose 31, the movable air blowing pipe 3 can always be connected to the air source for uninterrupted blowing. Through the electric push rod 13, the air blowing pipe 3 only moves radially, and the air blowing pipe 3 is inserted into the winding groove 15 by translating the stator 12. It can be seen that the air outlet pipe is directly inserted into the winding groove 15, which can better clean the dust in the winding groove 15. Through the rotation of the stator 12, the winding grooves 15 can be cleaned one by one. After the stator 12 rotates, it moves axially back and forth, and finally achieves the effect of blowing dust from the stator 12.

[0026] Regarding the driving mechanism, at least a cylinder can be connected to the slider 4, and the other end of the cylinder can be fixedly connected to the hollow tube 2, so that the slider 4 can be driven to translate by the extension and contraction of the cylinder. In this embodiment, the driving mechanism includes a screw 6 located in the hollow tube 2; one end of the screw 6 can be rotatably connected to the inner wall of one end of the hollow tube 2, and the other end thereof passes through a preset through hole on the side wall of the other end of the hollow tube 2, and is provided with a crank 61 for driving the screw 6 to rotate in the hollow tube 2; a first slide groove 23 is provided on the tube wall of the hollow tube 2; an inner convex portion 41 is provided in the middle of the slider 4, and the inner convex portion 41 extends from the first slide groove 23 into the interior of the hollow tube 2, and is provided with a screw hole 42, and the screw 6 is inserted into the screw hole 42, and is used to drive the slider 4 to translate when the screw 6 rotates. It can be seen that the screw 6 drives the slider 4 manually, which saves equipment resources and has low cost. The screw rod 6 is located inside the hollow tube 2, and the structure is compact, space-saving, and convenient for arranging the connecting rod and the air blowing pipe 3. Importantly, the connection between the screw rod 6 and the slider 4 has a thread self-locking function, which can fix the position of the air blowing pipe 3.

[0027] An exemplary sliding connection between the base 1 and the bottom plate 7 is that a slide rail 71 is provided on the upper surface of the bottom plate 7, and a second slide groove 14 corresponding to the slide rail 71 is provided on the base 1, and the base 1 is slidably connected to the bottom plate 7. If the slide rail 71 is provided on the base 1 and the second slide groove 14 is provided on the floor, the same effect is achieved.

[0028] In order to improve the efficiency of blowing and dust removal, there are multiple pairs of connecting rods hinged in the middle, which are evenly distributed around the axis of the hollow tube 2; each pair of connecting rods hinged in the middle is connected to one blowing pipe 3. It can be seen that each reciprocating movement of the stator 12 can clean more winding slots 15, thereby improving the dust removal efficiency.

[0029] In order to prevent disorderly discharge of dust, the shell 8 is buckled on the bottom plate 7; the stator 12, support roller 11, motor, base 1, electric push rod 13, and air blowing pipe 3 are all located inside the shell 8; the hollow tube 2 is fixedly connected to the side wall of one side of the shell 8, and its end for connecting to the air blowing pipe 3 is located inside the shell 8, and its end with the crank 61 is located outside the shell 8; the air collecting pipe 81 is fixedly arranged on the outer wall of the shell 8, and a plurality of branch pipes 82 connected to the air collecting pipe 81 are plugged into the shell 8, and the ends of the branch pipes 82 are connected to the ends of the hose 31; the air collecting pipe 81 is provided with an air inlet 84 for connecting to a high-pressure air source. It can be seen that the shell 8 is provided with a door for the stator 12 to enter and exit, so as to facilitate the storage and access of the stator 12, and is also provided with an air vent to maintain the air pressure balance inside and outside the shell 8. Of course, filters can be preset on the air vent to prevent dust leakage.

[0030] In order to actively collect dust and prevent dust from spilling out, a dust hood 83 is also included; the dust hood 83 is fixedly connected to the side wall of the shell 8 and arranged opposite to the air blowing pipe 3; the dust hood 83 is connected to the pipeline of the air suction purification device 85 arranged outside the shell 8, which is used to extract the air with dust in the shell 8 and purify it before discharging it. It can be seen that while blowing, the air in the shell 8 is actively sucked by the air suction purification device 85, and the dust enters the air suction purification device 85 for filtration and then discharged, and the environment is good.

[0031] When in use, first adjust the position of the slider 4, control the position of the air blowing pipe 3, then ventilate the air blowing pipe 3, and high-pressure gas is ejected from the air outlet 32 ​​at high speed; then, control the electric push rod 13 to drive the stator 12 to gradually approach until the air blowing pipe 3 at the air outlet 32 ​​is inserted into the winding groove 15, and the inner wall of the winding groove 15 is directly blown. Then, when the air outlet 32 ​​is exposed from the other end of the stator 12, the stator 12 is controlled to be stationary by the electric push rod 13, and then the stator 12 is driven to move in the opposite direction until the air blowing pipe 3 is pulled out of the winding groove 15. Then, the stator 12 is driven by the motor to rotate the preset angle so that the next winding groove 15 is aligned with the air blowing pipe 3, and then the above steps are repeated to clean the winding grooves 15 one by one until the dust blowing of all the winding grooves 15 is completed. Since the air blowing pipe 3 is inserted into the winding groove 15 to blow and remove dust, the cleaning effect is good. Under the condition of having the same dust blowing effect, the blowing time can be reduced, thereby improving the dust removal efficiency.

[0032] The advantages of this embodiment are as follows:

[0033] (1) The air blowing pipe 3 is inserted into the winding groove 15 to blow air and remove dust, which has a good cleaning effect and high efficiency.

[0034] (2) The radial position of the air blowing pipe 3 is adjustable, and can adapt to stators 12 of different diameters, with good adaptability.

[0035] (3) Through the arrangement of the screw rod 6 and the slider 4, the position adjustment operation of the air blowing pipe 3 is convenient and has a self-locking function.

[0036] (4) By providing the housing 8, disorderly discharge of dust is avoided, and the dust is collected by the dust hood 83, thereby optimizing the environment and protecting the health of the operators.

[0037] In summary, in this embodiment, the air blowing pipe 3 is inserted into the interior of the winding groove 15 to blow air directly from the interior of the winding groove 15, thereby improving the dust removal effect and efficiency, and is convenient to adjust and simple to operate.

[0038] It should be noted that the above is only to illustrate the working principle of this embodiment. Some assembly details are not unnecessary, but they are all prior art and do not involve the working principle of the utility model, so they are not described in detail. For example, the slider is installed on the hollow tube, the slider is connected to the screw, the screw is rotatably connected to the hollow tube, and so on. The hollow tube can be made in parts, and then welded and fixed into a whole after the slider and the screw are installed. These manufacturing and installation technologies are all prior art.

In order to make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described.
