[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The role of the accompanying drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0023] Referring to Figures 1-3 , an automotive motor shaft grinding device according to an embodiment of the present utility model includes a bottom plate 1. A rotating assembly and a grinding assembly disposed on one side of the clamping assembly are provided on the top of the bottom plate 1. The rotating assembly includes a clamping assembly and a top holding assembly disposed opposite to the clamping assembly; the clamping assembly includes a rotatable fixture 3, a slot 13 opened inside the fixture 3, and a plurality of positioning assemblies symmetrically arranged at equal intervals inside the fixture 3. The positioning assembly includes a linkage plate 6 slidably connected inside the fixture 3 and arranged parallel to the slot 13, a positioning plate 9 slidably connected inside the fixture 3 and arranged perpendicular to the linkage plate 6, a driving plate 10 slidably connected inside the fixture 3 and arranged parallel to the positioning plate 9, two limiting plates 11 slidably connected inside the fixture 3 and located between the linkage plate 6 and the slot 13, a reset plate 7 fixedly connected to the top of the linkage plate 6 and slidably connected inside the fixture 3, and a spring 8 fixedly connected to one side of the reset plate 7 and fixedly connected to the inside of the fixture 3. The driving plate 10 and the positioning plate 9 extend into the slot 13, and one end of the driving plate 10 located inside the slot 13 and both ends of the linkage plate 6 are provided with inclined surface structures. The bottom of the positioning plate 9 is provided with an arc structure. Both limiting plates 11 are fixedly connected to the corresponding driving plate 10 and positioning plate 9. One end of the driving plate 10 away from the slot 13 contacts the adjacent inclined surface structure of the linkage plate 6, and there is a certain gap between one end of the positioning plate 9 away from the slot 13 and the adjacent inclined surface structure of the linkage plate 6.

[0024] After the motor shaft is inserted into the slot 13, the end portion contacts the inclined surface of the driving plate 10. With the deepening of the motor shaft, the driving plate 10 can be pushed to move towards the linkage plate 6 under the action of the inclined surface. The moving linkage plate 6 and the action of its inclined surface can realize the horizontal movement operation towards the positioning plate 9. By the moving linkage plate 6 contacting the top of the positioning plate 9, the positioning plate 9 can be pushed to move towards the motor shaft side and the arc structure contacts the surface of the motor shaft, so that the positioning operation of the motor shaft can be realized under the action of the positioning plate 9, ensuring the stable connection work between the motor shaft and the fixture 3. After grinding, the motor shaft is taken out from the slot 13, and the reset operation of the linkage plate 6 and the driving plate 10 can be realized under the action of the spring 8 for the next grinding operation. The overall automation degree is high, the operation is simple, which is beneficial to improving the processing efficiency and product quality.

[0025] The rotating assembly further includes a first fixing plate 2 fixedly connected to the top of the bottom plate 1, a rotating shaft 4 rotatably connected inside the first fixing plate 2, and a first motor 5 fixedly connected to one side of the first fixing plate 2. The fixture 3 is fixedly connected to the end of the rotating shaft 4 away from the first motor 5, and the end of the rotating shaft 4 close to the first motor 5 is fixedly connected to the output shaft of the first motor 5.

[0026] Start the first motor 5, drive the fixture 3 to rotate through the rotating shaft 4, so as to drive the motor shaft to rotate for better grinding work.

[0027] The holding component includes a cylinder 15, an end plate 16 rotatably connected to the end of the piston rod of the cylinder 15, and a second fixing plate 14 fixedly connected to the top of the bottom plate 1 and arranged opposite to the first fixing plate 2. The cylinder 15 is fixedly connected to the side of the second fixing plate 14 close to the fixture 3.

[0028] Start the cylinder 15, and its piston rod pushes the end plate 16 to move towards the fixture 3 until the end plate 16 is in close contact with the other end of the motor shaft, forming a stable clamping and holding state. This combined clamping and holding method effectively ensures the stability and accuracy of the motor shaft during the grinding process.

[0029] The grinding assembly includes a moving plate 22 connected movably, a mounting plate 24 hinged to the top of the moving plate 22, a third motor 25 fixedly connected to the top of the mounting plate 24, a grinding wheel 26 fixedly connected to the output shaft of the third motor 25, a fourth fixing plate 27 fixedly connected to the top of the moving plate 22, and an electric push rod 23 rotatably connected to the side of the fourth fixing plate 27 close to the mounting plate 24. The piston rod of the electric push rod 23 is rotatably connected to the top of the mounting plate 24. The grinding assembly further includes a third fixing plate 19 fixedly connected to the top of the bottom plate 1, a lead screw 20 rotatably connected inside the third fixing plate 19, and a second motor 21 fixedly connected to one side of the third fixing plate 19. The moving plate 22 is slidably connected inside the third fixing plate 19 and is threadedly connected to the lead screw 20. The end of the lead screw 20 close to the second motor 21 penetrates through the third fixing plate 19 and is fixedly connected to the output shaft of the second motor 21.

[0030] After the motor shaft is stably clamped, start the second motor 21, and its output shaft drives the lead screw 20 to rotate. The rotating lead screw 20 can drive the moving plate 22 to move left and right. At the same time, the piston rod of the electric push rod 23 adjusts the angle of the mounting plate 24 to ensure that the grinding wheel 26 maintains an appropriate contact pressure with the surface of the motor shaft. Start the third motor 25, and its output shaft drives the grinding wheel 26 to rotate at a high speed, and start to grind the surface of the motor shaft.

[0031] On one side of the bottom plate 1 close to the first fixing plate 2, a collecting groove 18 is fixedly connected. Between the first fixing plate 2 and the second fixing plate 14 and below the fixture 3, a material guiding plate 17 inclined towards the collecting groove 18 is fixedly connected. The waste and debris generated by grinding fall into the collecting groove 18 under the guidance of the material guiding plate 17, facilitating subsequent cleaning and processing.

[0032] At one end of the positioning plate 9 located inside the slot 13, a guiding plate 12 is fixedly connected. On one side of the guiding plate 12 close to the opening of the slot 13, it is set as an inclined surface structure. When the motor shaft is inserted into the slot 13 and contacts the guiding plate 12, the positioning plate 9 can be pushed to move outward under the action of the inclined surface as the motor shaft moves.

[0033] Working principle: After the motor shaft is inserted into the slot 13, the end part contacts the inclined surface of the driving plate 10. As the motor shaft penetrates deeper, the driving plate 10 can be pushed to move towards the linkage plate 6 under the action of the inclined surface. The moving linkage plate 6 and the action of its inclined surface can realize the horizontal movement operation towards the positioning plate 9. By the moving linkage plate 6 contacting the top of the positioning plate 9, the positioning plate 9 can be pushed to move towards the motor shaft side and make the arc structure contact the surface of the motor shaft. Thus, the positioning operation of the motor shaft can be realized under the action of the positioning plate 9, ensuring the stable connection work between the motor shaft and the fixture 3. Then start the cylinder 15, and its piston rod pushes the end plate 16 to move towards the fixture 3 until the end plate 16 is in close contact with the other end of the motor shaft, forming a stable clamping and holding state. This combined clamping and holding method effectively ensures the stability and precision of the motor shaft during the grinding process.

[0034] Start the first motor 5, drive the fixture 3 to rotate through the rotating shaft 4, thereby driving the motor shaft to rotate. At the same time, start the second motor 21, and its output shaft drives the lead screw 20 to rotate. The rotating lead screw 20 can drive the moving plate 22 to move left and right. At the same time, the piston rod of the electric push rod 23 adjusts the angle of the mounting plate 24 to ensure that the grinding wheel 26 maintains an appropriate contact pressure with the surface of the motor shaft. Start the third motor 25, and its output shaft drives the grinding wheel 26 to rotate at a high speed, and start to grind the surface of the motor shaft. The overall automation degree is high, the operation is simple, which is beneficial to improving the processing efficiency and product quality.

[0035] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the gist of the present invention.
