Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motor maintenance equipment, and in particular to a motor insulation plate polishing device with adjustable polishing depth. BACKGROUND

[0002] The motor insulation plate is a key functional component inside the motor, used to isolate the stator and the rotor, the winding and the frame, and has the functions of structural support and stress transmission. It needs to have excellent electrical insulation, mechanical strength, heat resistance and aging resistance. The common material is epoxy glass cloth plate, etc. According to the installation position and function, it can be divided into stator insulation plate, rotor insulation plate and thrust insulation plate. The thrust insulation plate is usually a half-ring. After long-term operation of the motor, the surface of the thrust insulation plate is prone to mechanical wear, dirt carbonization, local aging and other damages. Polishing can repair the damage and restore the insulation performance. The polishing can ensure the surface flatness, avoid the motor runout exceeding the standard due to uneven stress, and accurately control the thickness deviation to adapt to the assembly accuracy, while prolonging the service life of the insulation plate and the motor, reducing the maintenance cost. The traditional manual polishing has insufficient precision, and the precise polishing of the special polishing device can better meet the needs of modern motors.

[0020] To sum up, compared with the prior art, the application has the following advantages after adopting the above structure:

[0021] 1、In the application, the positioning assembly of the device solves the defects of traditional single clamping mode through multiple innovative structures. First, the inner tooth ring of the inner wall of the annular frame is meshed and transmitted with the first transmission gear, and is driven by the first reciprocating push rod, so that multiple L-shaped movable plates can be synchronously moved radially, and different sizes of half-ring thrust insulating plates can be accurately fitted without frequent replacement of clamps. Second, a double-buffering structure is formed between the movable frame on one side of the L-shaped movable plate and the movable frame through the first and second buffer springs, so that the special position of the top corner of the insulating plate can be tightly clamped by the concave clamping wheel with an arc surface, and the over-pressing force can be offset during clamping to avoid damage to the edge of the insulating plate due to rigid clamping.

[0022] 2、In the application, the polishing assembly is finely designed to realize accurate adjustment and efficient polishing of the grinding depth. On the one hand, the reciprocating lifting mechanism in the center frame adopts a transmission mode of meshing the second transmission gear with the toothed rack seats on both sides, and is driven by the second reciprocating push rod, so that the polishing frame and the scraping frame can be stably lifted along the slide rail, and the grinding depth of the polishing seat can be accurately controlled according to the wear degree of the insulating plate. On the other hand, the cutting edge on one side of the scraping frame can quickly remove stubborn dirt and aging layers, and the beveled polishing seat at the bottom of the polishing frame can uniformly polish the surface of the insulating plate. The two work together, compared with the traditional single polishing method, not only shortens the polishing time, but also ensures the flatness of the surface of the insulating plate, avoids the hidden danger of excessive motor runout caused by uneven stress, and meets various polishing needs from light repair to deep renovation.

[0023] 3、The combination of the scrap cleaning assembly and the waste collecting hopper in the application solves the problem of traditional scrap accumulation. Firstly, the exhaust hole on the scraping frame is in communication with the exhaust pipe and the first corrugated pipe, the airflow discharged by the air extractor can be blown to the area scraped by the scraping frame through the exhaust hole, so as to clean the scraped scrap in time. Meanwhile, the exhaust pipe is in communication with the exhaust hole and the suction hole on the polishing frame, so that the generated scrap can be sucked in real time when the polishing seat is working, thereby avoiding the attachment of the scrap on the surface of the insulating plate to cause secondary scratches, preventing the scrap from scattering into the device to affect the operation of the parts, forming a double cleaning mode of simultaneous scraping and blowing and simultaneous polishing and suction, and ensuring that the polishing area is always clean. In addition, the inclined waste collecting hopper at the bottom of the exhaust hole can collect the scrap discharged by the U-shaped pipe through the exhaust pipe and the scrap scraped by the scraping frame, and finally uniformly discharge the scrap through the exhaust pipe, which not only facilitates subsequent scrap treatment, but also reduces the erosion of the scrap on the device, prolongs the service life of the device, and at the same time guarantees the surface quality of the polished insulating plate, avoiding the influence of the scrap on the insulation performance.

[0024] 4、In the application, the auxiliary pressing assembly on one side of the polishing frame and the scraping frame is matched with the ball on the bottom of the I-shaped movable seat and the pressing spring, so that the surface of the insulating plate can be flexibly pressed during polishing, which not only ensures that the insulating plate does not move during rotary polishing, but also reduces the friction resistance with the insulating plate through the rolling of the ball, avoiding affecting the rotation accuracy of the insulating plate, further guaranteeing the stability of the polishing process and reducing the working strength of the operator.

The dimensions of the force insulation plate body 6, the movable frame 35 on the top of one side of the L-shaped movable plate 33, under the buffering action of the first buffer spring 315, moves along the guide port 316 in the slot, the movable frame 37 under the buffering action of the second buffer spring 317 moves along the inner wall of the movable frame 35, driving the clamping wheel 38 at the bottom of the movable frame 37 to engage with the top corner of the force insulation plate body 6, the concave structure on the surface of the clamping wheel 38 fits the corner, the arc-shaped outer wall avoids damage to the insulation plate, and achieves flexible and stable positioning of the force insulation plate body 6;

[0055] Next, the motor 71 in the rotating mechanism 7 is started by the controller. The output shaft of the motor 71 drives the drive gear 74 to rotate. The drive gear 74 meshes with the outer gear ring 73 at the top of the outer wall of the annular frame 31, causing the annular frame 31 to rotate along the bearing on the inner wall of the placement groove 2. The annular slide at the bottom of the annular frame 31 slides along the annular slide groove 32. At the same time, the annular frame 31 drives the central shaft 9 to rotate synchronously through the synchronous rotating frame 4, thereby causing the thrust insulating plate body 6 to rotate stably with the annular frame 31. Simultaneously, the second reciprocating push rod 52 at the top of the central frame 51 in the grinding assembly 5 is started by the controller. The second reciprocating push rod 52 pushes the rack seat 54 to slide along the slide rail 59 on the inner wall of the central frame 51. The rack seat 54 drives the second transmission gear 53 to rotate, causing the rack seats 54 on both sides to move synchronously in opposite directions, respectively driving the grinding frame 55 and the scraper frame 57 to rotate along the annular frame 31. The movable groove 58 moves synchronously in opposite directions to adjust the grinding depth. When rotating, the blade edge 510 at the bottom of the arc groove on one side of the scraper 57 first contacts the top of the thrust insulation plate body 6. The blade edge 510 removes stubborn dirt and aging layer from the surface of the insulation plate. Then, the height of the grinding frame 55 is adjusted so that the grinding seat 56 in the groove at the bottom of the grinding frame 55 contacts the top of the thrust insulation plate body 6. The grinding seat 56 grinds the surface of the insulation plate evenly. At the same time, in the auxiliary clamping assembly 8 on one side of the grinding frame 55 and the scraper 57, the I-shaped movable seat 82 moves down along the through hole of the connecting plate 81 under the action of the clamping spring 83. The ball 84 at the bottom of the I-shaped movable seat 82 contacts the surface of the thrust insulation plate body 6 to form a flexible clamping, preventing the insulation plate from moving. The ball 84 also reduces frictional resistance and does not affect the rotation of the insulation plate.

[0056] In the polishing process, the controller is used to start the exhaust machine 124 in the waste cleaning assembly 12, the airflow generated by the exhaust machine 124 passes through the first bellows 125 and the exhaust pipe 126 to enter the exhaust hole 129 on the scraping frame 57, and blows to the scraping area to clean the waste generated by scraping; at the same time, the suction force generated by the exhaust machine 124 passes through the second bellows 128 and the exhaust pipe 127 to enter the exhaust hole 1210 on the polishing frame 55, and then passes through the suction hole 1211 to suck the waste generated by polishing, the waste enters the U-shaped pipe 121 through the exhaust hole 1210, the exhaust pipe 127 and the second bellows 128, the inclined filter screen 1212 on the inner wall of the U-shaped pipe 121 filters the waste, the filtered waste is discharged into the waste collecting hopper 11 through the waste removal pipe 122 and the on-off valve 123, and finally the sealing cover at the bottom end of the waste discharge pipe 10 is opened, so that the waste in the waste collecting hopper 11 is discharged through the waste discharge pipe 10.

[0057] In combination with the actual demand, the above-mentioned embodiments of the present application are not limited to the scope, and various changes made by the technical personnel within the scope of knowledge do not deviate from the concept of the present application, and still fall within the protection scope of the present application.
