[0029] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0030] See also Figure 1-Figure 4 , Figure 1 It is a schematic diagram of the three-dimensional structure of the motor shaft grinding device provided by the embodiment of the utility model; Figure 2 It is a three-dimensional structural schematic diagram of a clamping assembly in a motor shaft grinding device provided by an embodiment of the utility model; Figure 3 It is a three-dimensional structural schematic diagram of a grinding component in a motor shaft grinding device provided by an embodiment of the utility model; Figure 4 The motor shaft grinding device 1 includes a base 11, a clamping assembly 12 and a grinding assembly 13. The clamping assembly 12 includes a fixed plate 121 and at least two clamping plates 122 slidably connected to the fixed plate 121 to clamp the motor 2. The fixed plate 121 is fixed to the base 11. The grinding assembly 13 includes a grinding support rod 123 and a grinding head 133. The grinding support rod 123 is installed on the base 11. The grinding head 133 is rotatably connected to the grinding support rod 123 to grind the motor shaft 21.

[0031] By fixing the fixing plate 121 on the base 11, the clamping plate 122 is slidably connected to the fixing plate 121 to clamp the motor 2 under the sliding action of the clamping plate 122, the grinding support rod 123 is installed on the base 11, and the grinding head 133 is installed on the grinding support rod 123, so that the motor shaft 21 can be polished under the grinding action of the grinding head 133, thereby improving the smoothness of the motor shaft 21.

[0032] In one embodiment of the utility model, the motor 2 to be polished is clamped between the clamping plates 122 to fix the motor 2, and then the position of the polishing support rod 123 and the position of the polishing head 133 are adjusted so that the polishing head 133 fits the motor shaft 21, and then the clamped motor 2 is energized to rotate the motor shaft 21, and the rotating motor shaft 21 generates friction with the polishing head 133, thereby achieving the polishing effect on the motor shaft 21 and improving the smoothness of the motor shaft 21.

[0033] Compared with the prior art, the motor shaft grinding device 1 of the utility model does not need to disassemble the motor 2 when grinding and polishing the motor shaft 21, thereby reducing the time cost and labor cost of reworking and polishing the motor shaft 21. The motor 2 with grinding is fixed between the clamping plates 122 and the motor 2 is powered on, so that the grinding head 133 can polish and grind the rotating motor shaft 21, saving time and labor and improving the grinding efficiency of the motor shaft 21.

[0034] See also Figure 3 In an embodiment of the utility model, the grinding support rod 123 includes a first support rod 131 and a second support rod 132, the first support rod 131 is installed on the base 11, the grinding head 133 is connected to the second support rod 132, and the second support rod 132 is plugged into the first support rod 131 to adjust the grinding height of the grinding head 133.

[0035] By installing the first support rod 131 on the base 11 and plugging the second support rod 132 with the first support rod 131, the grinding head 133 is rotatably connected to the second support rod 132, so that the height of the grinding head 133 can be adjusted by adjusting the plugging depth of the second support rod 132 and the first support rod 131, thereby realizing the adjustment of the friction force between the grinding head 133 and the motor shaft 21. That is, when the height of the grinding head 133 is higher or lower than the central axis of the motor shaft 21, the friction force between the grinding head 133 and the motor shaft 21 is reduced; when the height of the grinding head 133 is equal to the height of the central axis of the motor shaft 21, the friction force between the grinding head 133 and the motor shaft 21 is increased, thereby realizing the adjustment of the grinding force of the motor shaft 21, avoiding excessive or insufficient grinding force resulting in the quality of the motor shaft 21 after grinding not meeting the standards.

[0036] See also Figure 4 In an embodiment of the utility model, the grinding assembly 13 also includes a first driving member 134 and a screw rod 135. A protruding slider 1311 is fixed to the bottom of the first support rod 131. A slide groove 111 for the slider 1311 to slide is provided on the base 11. The first driving member 134 is fixed on the base 11 and connected to the slider 1311 through the screw rod 135 to drive the slider 1311 to slide in the slide groove 111.

[0037] By opening a slide groove 111 on the base 11 and setting a slider 1311 at the bottom of the first support rod 131, the first support rod 131 can slide on the base 11 under the sliding connection between the slider 1311 and the slide groove 111, and then adjust the grinding head 133 to grind different positions of the motor shaft 21, that is, adjust the grinding head 133 to move in the length direction of the motor shaft 21, and then cooperate with the rotation of the motor shaft 21 to realize the grinding of the entire cylindrical surface of the motor shaft 21, so that the motor shaft 21 can be polished more evenly, thereby improving the grinding quality of the motor shaft 21.

[0038] By fixing the first driving member 134 on the base 11, one end of the screw rod 135 is connected to the first driving member 134, and the other end is threadedly connected to the slider 1311, so that the screw rod 135 can be driven to rotate under the drive of the first driving member 134, and the rotating screw rod 135 drives the slider 1311 to slide in the slide groove 111, thereby driving the first support rod 131 to move on the base 11, so as to adjust the position of the grinding head 133, so that the grinding head 133 can grind the entire cylindrical surface of the motor shaft 21, so that the motor shaft 21 can be polished more evenly, and the grinding quality of the motor shaft 21 can be improved.

[0039] It can be understood that the first driving member 134 includes any one of a servo motor 2 , a stepping motor 2 , and a synchronous motor 2 to drive the lead screw to rotate and drive the first support rod 131 to move on the base 11 .

[0040] See also Figure 3 In an embodiment of the utility model, the grinding assembly 13 also includes a second driving member 136, and the grinding head 133 is connected to the second support rod 132 through the second driving member 136 to adjust the distance between the grinding head 133 and the central axis of the motor shaft 21 under the drive of the second driving member 136.

[0041] By fixing the second driving member 136 on the second support rod 132 and connecting the grinding head 133 with the second driving member 136, the grinding head 133 can be driven to move under the drive of the second driving member 136, so that the distance between the grinding head 133 and the central axis of the motor shaft 21 changes, and then the friction force between the grinding head 133 and the motor shaft 21 is adjusted. That is, when the second driving member 136 drives the grinding head 133 to move in the direction of the motor shaft 21, the friction force between the grinding head 133 and the motor shaft 21 increases; when the second driving member 136 drives the grinding head 133 to move in the direction away from the motor shaft 21, the friction force between the grinding head 133 and the motor shaft 21 decreases, thereby realizing the adjustment of the grinding force of the motor shaft 21, avoiding excessive or insufficient grinding force resulting in poor quality of the motor shaft 21 after grinding.

[0042] It can be understood that the second driving member 136 includes any one of a pneumatic cylinder, an electric cylinder, and a hydraulic cylinder to drive the grinding head 133 to move toward or away from the motor shaft 21 .

[0043] In the embodiment of the present invention, the grinding assembly 13 further includes a third driving member 137 , which is installed between the grinding head 133 and the second driving member 136 , so as to drive the grinding head 133 to rotate under the driving of the third driving member 137 .

[0044] By installing the third driving member 137 between the second driving member 136 and the grinding head 133, the third driving member 137 and the grinding head 133 can be driven to move synchronously toward or away from the direction of the motor shaft 21 when the second driving member 136 is working, so as to adjust the friction between the grinding head 133 and the motor shaft 21. At the same time, the grinding head 133 is driven to rotate under the drive of the third driving member 137, so that the rotating grinding head 133 can grind the motor shaft 21. In this embodiment, the grinding head 133 is driven to rotate under the drive of the third driving member 137. Therefore, when grinding the motor shaft 21, the grinding and polishing effect of the motor shaft 21 can be achieved without energizing the motor 2, thereby reducing the difficulty of the operation when grinding the motor shaft 21.

[0045] It can be understood that the third driving member 137 includes any one of a servo motor 2 , a stepper motor 2 , and a synchronous motor 2 to drive the grinding head 133 to rotate, thereby achieving a grinding and polishing effect on the motor shaft 21 .

[0046] See also Figure 1 In an embodiment of the utility model, two groups of grinding assemblies 13 are provided, and the two groups of grinding assemblies 13 are symmetrically arranged on both sides of the motor shaft 21, so that the grinding heads 133 in the two groups of grinding assemblies 13 can grind the motor shaft 21 at the same time, thereby improving the grinding efficiency of the motor shaft 21.

[0047] See also Figure 2 In the embodiment of the utility model, a through hole 1211 is opened on the surface of the fixing plate 121, and the size of the through hole 1211 is larger than the diameter of the motor shaft 21 so as to allow the motor shaft 21 to pass through.

[0048] By opening a through hole 1211 on the surface of the fixing plate 121, when the clamping plate 122 clamps the motor 2, the motor shaft 21 can pass through the through hole 1211 to reach the position of the grinding assembly 13, so that the grinding head 133 can grind the motor shaft 21. Under the isolation effect of the fixing plate 121, the grinding iron chips can be prevented from splashing into the housing of the motor 2 and affecting the service life of the motor 2.

[0049] In the embodiment of the present utility model, the number of the clamping plates 122 is four, and the four clamping plates 122 are arranged in an array around the through hole 1211 to clamp the motor 2 .

[0050] By setting four clamping plates 122 and arranging the four clamping plates 122 in an array around the through hole 1211, a clamping space for clamping the motor 2 is formed inside the four clamping plates 122, so that the motor 2 can be placed in the clamping space, and the motor 2 can be clamped with the cooperation of the four clamping plates 122, thereby improving the firmness of the clamping assembly 12 in clamping the motor 2 and avoiding the motor 2 from falling off the clamping plate 122 when the motor shaft 21 is polished.

[0051] In the embodiment of the present invention, the inner surface of the clamping plate 122 is a curved surface to fit the surface of the motor 2 , and the surface of the curved surface is provided with anti-slip grooves 1221 .

[0052] By setting the inner surface of the clamping plate 122 as a curved surface, the contact area between the clamping plate 122 and the motor 2 is larger when the clamping plate 122 clamps the motor 2, thereby improving the clamping firmness of the clamping plate 122 on the motor 2 and preventing the motor 2 from falling off the clamping assembly 12. By setting anti-slip grooves 1221 on the curved surface, the clamping firmness of the clamping plate 122 on the motor 2 is further improved, preventing the position of the motor 2 from changing during the grinding process of the motor shaft 21, thereby affecting the grinding quality of the motor shaft 21.

[0053] In the embodiment of the present invention, the clamping assembly 12 further includes a support rod 123 . The support rod 123 is fixed to two sides of the fixing plate 121 and fixedly connected to the base 11 .

[0054] By arranging support plates on both sides of the fixing plate 121 and fixing the support rod 123 to the base 11, the structural strength of the fixing plate 121 on the base 11 is improved, so that the motor shaft grinding device 1 can grind the motor shaft 21 and improve the grinding efficiency of the motor shaft 21.

[0055] In the embodiment of the present utility model, the clamping assembly 12 further includes an adjusting rod 124 , the adjusting rod 124 passes through the fixing plate 121 and is rotatably connected to the clamping plate 122 , and the adjusting rod 124 is threadedly connected to the fixing plate 121 .

[0056] The adjusting rod 124 passes through the fixing plate 121 and is threadedly connected to the fixing plate 121. The adjusting rod 124 is rotatably connected to the clamping plate 122. Therefore, when the clamping plate 122 is used to clamp the motor 2, the size of the clamping space inside the clamping plate 122 can be adjusted by rotating the adjusting rod 124. That is, when the adjusting rod 124 is rotated clockwise, the clamping plate 122 moves toward the outside of the clamping space, and the clamping space becomes larger, so as to clamp a larger motor 2. When the adjusting rod 124 is rotated counterclockwise, the clamping plate 122 moves toward the inside of the clamping space, and the clamping space becomes smaller, so as to clamp a smaller motor 2. This allows the motor shaft grinding device 1 to grind motor shafts 21 of different sizes, thereby improving the scope of application of the motor shaft grinding device 1.

[0057] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
