[0001] The utility model relates to the field of grinding devices, in particular to a grinding device for the shell of a servo motor. Background Technique

[0002] A servo motor refers to an engine that controls the operation of mechanical components in a servo system and is an auxiliary motor indirect speed change device; servo motors are mainly divided into two categories: DC servo motors and AC servo motors. AC servo motors are mostly brushless motors, with complex control but easy to achieve intelligence, while DC servo motors are divided into brushed and brushless types.

[0003] The processing process of a servo motor usually includes the following steps: designing the system, preparing materials, rough machining, shell grinding, coating treatment, assembly and debugging, and packaging and leaving the factory; among them, shell grinding is one of the important steps in the processing of servo motors. Shell grinding treatment can remove the scratch marks and burrs on the surface of the casing, making its surface flatter, enhancing the aesthetics and durability of the casing.

[0004] The existing grinding of the servo motor shell usually fixes the servo motor shell with a fixing device and then grinds it. It is found in production and observation that after grinding one side of the servo motor shell, a series of operation steps such as disassembling the servo motor, adjusting the angle, and re-fixing are required, which will make the operation of grinding the servo motor shell more cumbersome and increase the working time required for grinding the servo motor shell.

[0005] Therefore, a grinding device for the shell of a servo motor is proposed for the above problems. Content of the Utility Model

[0026] The following gives specific embodiments.

[0027] Please refer to Figures 1 to 6As shown in the figure, a grinding device for the housing of a servo motor according to an embodiment of the present invention includes a support base 1; a first connecting plate 102 is fixedly connected to the top of the support base 1; a sliding plate 103 is slidably connected to the middle of the first connecting plate 102; a grinding assembly 104 is installed at the bottom of the sliding plate 103; a linear motor 105 is fixedly connected to the top of the support base 1; an output end of the linear motor 105 is fixedly connected to a cross plate 106; a cylinder 107 is fixedly connected to the top of the cross plate 106; an output end of the cylinder 107 is fixedly connected to a first pressing plate 108; a vertical plate 109 is fixedly connected to the top of the cross plate 106; a driving motor 110 is fixedly connected to the middle of the vertical plate 109; an output end of the driving motor 110 is fixedly connected to a rotating shaft 111; the rotating shaft 111 and the vertical plate 109 are arranged in a penetrating manner and are rotatably connected; a second pressing plate 112 is fixedly connected to the end of the rotating shaft 111; during operation, the motor housing is placed on the top of the cross plate 106 and one side of it is abutted against the second pressing plate 112, and then the cylinder 107 is started to make the first pressing plate 108 approach the motor housing. When the first pressing plate 108 contacts the motor housing, it will extrude the motor housing, and at this time the motor housing will be fixed. Then the linear motor 105 can be started to make the cross plate 106 drive the motor housing to move towards the grinding assembly 104. When the motor housing contacts the grinding assembly 104, its surface will be ground. When one side of the motor housing is ground, the driving motor 110 can be started to make the rotating shaft 111 drive the second pressing plate 112 to rotate, and the second pressing plate 112 will drive the motor housing to rotate together, so that the grinding assembly 104 grinds the other side of the motor housing. The above steps are repeated multiple times, and finally the grinding assembly 104 can complete the grinding work on the surface of the motor housing; starting the driving motor 110 can make the second pressing plate 112 drive the motor housing to rotate, so that the grinding assembly 104 can easily grind multiple surfaces of the motor housing, improving the convenience of the device when grinding the motor housing and shortening the working time required for the device to grind the motor housing.

[0028] Please refer to Figure 3 and Figure 4As shown, a second connecting plate 2 is rotatably connected to the middle of the rotating shaft 111; the second connecting plate 2 and the second pressing plate 112 are in a communicating relationship; a first air pipe 22 communicates with the middle of the second connecting plate 2; a plurality of first round holes 24 are formed in the middle of the second pressing plate 112; a plurality of suction cups 23 are fixedly connected to the middle of the second pressing plate 112; the suction cups 23 and the first round holes 24 are arranged in correspondence; the staff can externally connect the first air pipe 22 to an air pump so that the air pump evacuates the inside of the second connecting plate 2 through the first air pipe 22. At this time, the air around the second pressing plate 112 will enter the inside of the second pressing plate 112 through the first round holes 24 and flow into the inside of the second connecting plate 2, causing a negative pressure state at the first round holes 24. When the motor housing comes into contact with the second pressing plate 112, the motor housing will also come into contact with the suction cups 23. At this time, the motor housing will be adsorbed and fixed by the suction cups 23. Subsequently, the cylinder 107 can be started to drive the first pressing plate 108 to squeeze the motor housing; the motor housing will be adsorbed by the suction cups 23 due to the negative pressure state at the first round holes 24, enhancing the stability of the device for fixing the motor housing, reducing the shaking of the motor housing during the grinding process by the grinding assembly 104, and at the same time improving the convenience of supporting the motor housing by the first pressing plate 108 before squeezing it.

[0029] Please refer to Figure 3 and Figure 4 As shown, a plurality of water sacs 3 are fixedly connected to the middle of the second pressing plate 112; the water sacs 3 and the suction cups 23 are arranged in correspondence; a plurality of springs 34 are fixedly connected to the inner side wall of the second pressing plate 112; the ends of adjacent springs 34 are fixedly connected to a first fixing plate 33; a sliding rod 32 is fixedly connected to the middle of the first fixing plate 33; a plurality of blades 35 are fixedly connected to the middle of the sliding rod 32; the sliding rod 32 and the first round holes 24 are in clearance fit; water is injected into the water sacs 3. When the motor housing comes into contact with the suction cups 23, the motor housing will also come into contact with the sliding rod 32 and cause the sliding rod 32 to slide along the first round holes 24. When the sliding rod 32 moves, it will drive the blades 35 to move together, so that the blades 35 will cut the water sacs 3 when moving. At this time, the water in the water sacs 3 will flow out and moisten the surfaces of the suction cups 23 and the motor housing, making the fit between the suction cups 23 and the motor housing closer, enhancing the adsorption effect of the suction cups 23 on the motor housing, and further improving the stability of the device for fixing the motor housing.

[0030] Please refer to Figure 4As shown, a sphere 4 is fixedly connected to the middle of the sliding rod 32; the sphere 4 and the first round hole 24 are in sliding fit; under normal conditions, the sphere 4 seals the first round hole 24. When the sliding rod 32 moves, it will drive the sphere 4 to move together. When the sphere 4 moves, it will disengage from the first round hole 24, making the first round hole 24 in an open state. At this time, because the total air pressure in the second pressing plate 112 remains unchanged, the air flow at the first round hole 24 in contact with the motor housing will be greater, enhancing the negative pressure effect at the first round hole 24 and further enhancing the adsorption capacity of the suction cup 23 to the motor housing.

[0031] Please refer to Figure 5 and Figure 6 As shown, a second fixed plate 5 is fixedly connected to the bottom of the sliding plate 103; a second air pipe 52 communicates with the top of the second fixed plate 5; a plurality of second round holes 53 are formed in the middle of the second fixed plate 5; the second fixed plate 5 is of an arc-shaped structure; when the grinding assembly 104 grinds the motor housing, the second air pipe 52 can be externally connected to an air pump, and the air pump will send air into the second fixed plate 5 through the second air pipe 52. The air flow will spray out from the second round holes 53 and reach the surface of the grinding assembly 104, accelerating the air flow around the grinding assembly 104, reducing the heat generated on the surface of the grinding assembly 104 during grinding, realizing the cooling of the grinding assembly 104 by the device, and prolonging the service life of the grinding assembly 104.

[0032] Please refer to Figure 6 As shown, a plurality of guiding plates 6 are fixedly connected to the inner side wall of the second fixed plate 5; the guiding plates 6 and the second round holes 53 are arranged correspondingly; the guiding plates 6 are of an arc-shaped structure; when the air flow sprays out from the second round holes 53, it will reach the surface of the guiding plates 6. Because the surface of the guiding plates 6 is of an arc-shaped structure, the air flow will flow along the surface of the guiding plates 6, expanding the flow range of the air flow and increasing the contact area between the air flow and the grinding assembly 104.

[0033] Please refer to Figure 6 As shown, a plurality of hole plates 7 are fixedly connected to the inner side wall of the second fixed plate 5; the hole plates 7 are arranged staggeredly; when the grinding assembly 104 grinds the motor housing, there will be flying debris. When the debris enters the inside of the second fixed plate 5 through the second round holes 53, the hole plates 7 will intercept the debris, reducing the debris entering the second air pipe 52 and reducing the pollution of the second air pipe 52 by the debris.

[0034] Working principle: Place the motor housing on top of the cross plate 106 and press one side of it against the second pressing plate 112. Then start the cylinder 107 to make the first pressing plate 108 approach the motor housing. When the first pressing plate 108 contacts the motor housing, it will squeeze the motor housing, and at this time, the motor housing will be fixed. Then, start the linear motor 105 to make the cross plate 106 drive the motor housing to move towards the grinding assembly 104. When the motor housing contacts the grinding assembly 104, its surface will be ground. When one side of the motor housing is ground, start the driving motor 110 to make the rotating shaft 111 drive the second pressing plate 112 to rotate. The second pressing plate 112 will drive the motor housing to rotate together, so that the grinding assembly 104 can grind the other side of the motor housing. Repeat the above steps multiple times, and finally the grinding assembly 104 can complete the grinding work on the surface of the motor housing; The staff can connect the first air pipe 22 to an air pump, and the air pump will pump air into the second connecting plate 2 through the first air pipe 22. At this time, the air around the second pressing plate 112 will enter the inside of the second pressing plate 112 through the first round hole 24 and flow into the inside of the second connecting plate 2, making a negative pressure state form at the first round hole 24. When the motor housing contacts the second pressing plate 112, the motor housing will also contact the suction cup 23. At this time, the motor housing will be adsorbed and fixed by the suction cup 23. Then, start the cylinder 107 to drive the first pressing plate 108 to squeeze the motor housing; When the motor housing contacts the suction cup 23, the motor housing will also contact the sliding rod 32 and make the sliding rod 32 slide along the first round hole 24. When the sliding rod 32 moves, it will drive the blade 35 to move together, so that the blade 35 will cut the water bag 3 when it moves. At this time, the water in the water bag 3 will flow out and moisten the surface of the suction cup 23 and the motor housing, making the fit between the suction cup 23 and the motor housing closer; Under normal conditions, the spherical ball 4 will seal the first round hole 24. When the sliding rod 32 moves, it will drive the spherical ball 4 to move together. When the spherical ball 4 moves, it will separate from the first round hole 24, making the first round hole 24 in an open state. At this time, because the total air pressure in the second pressing plate 112 remains unchanged, the air flow at the first round hole 24 in contact with the motor housing will be greater; When the grinding assembly 104 grinds the motor housing, connect the second air pipe 52 to an air pump, and the air pump will send air into the second fixing plate 5 through the second air pipe 52. The air flow will spray out from the second round hole 53 and reach the surface of the grinding assembly 104, accelerating the air flow around the grinding assembly 104; When the air flow sprays out from the second round hole 53, it will reach the surface of the guiding plate 6. Because the surface of the guiding plate 6 is an arc structure, the air flow will flow along the surface of the guiding plate 6, expanding the flow range of the air flow; When the grinding assembly 104 grinds the motor housing, there will be flying debris. When the debris enters the inside of the second fixing plate 5 through the second round hole 53, the orifice plate 7 will intercept the debris, reducing the debris entering the second air pipe 52.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model.
