Description

Technical Field

[0001] The present invention belongs to the technical field of motor shaft processing, and specifically relates to a motor shaft processing device for a new energy vehicle. Background Art

[0002] The motor shaft is one of the indispensable core components of the motor. It is mainly responsible for supporting the rotating parts, transmitting torque and ensuring the accurate relative position of the rotating parts to the stator. The motor shaft is one of the indispensable core components of the motor. The motor shaft is mainly responsible for supporting the rotating parts, transmitting torque and ensuring the accurate relative position of the rotating parts to the stator. According to whether there are steps on the shaft, it can be divided into a smooth shaft and a stepped shaft. The smooth shaft is often made of cold-drawn round steel and is suitable for situations where processing time needs to be reduced, such as in micro motors. The stepped shaft can easily and reliably install a variety of components, so it is adopted by most motors.

[0003] However, the existing new energy vehicle motor shaft processing devices often have some problems during actual use: first, in the existing motor shaft processing process, the motor shaft needs to be clamped by a clamping mechanism, and then polished and processed by a processing knife. At the beginning and end of the processing, since the clamping position is fixed and will not move, it will block the processing knife from processing the clamping position. After grinding one side of the motor shaft, it is often necessary to turn the motor shaft over, and after re-clamping the motor shaft, the unprocessed part is processed. There are many steps in this process, which will lead to a decrease in work efficiency and affect the processing speed; secondly, in the process of clamping the motor shaft, the clamping force may be too large to cause indentations on the surface of the shaft, thereby affecting the surface accuracy of the motor shaft and thus affecting the normal use of the motor shaft.

[0008] Preferably, a first motor shaft is arranged in the middle of the clamping plate, the radius of the first motor shaft is smaller than the radius of the clamping plate, and the clamping plate is arranged corresponding to the first motor shaft.

[0009] Preferably, a plurality of arc protrusions are arranged on the outer side of the first rotating shaft, and the internal through holes of the first pulley and the clutch wheel are arranged corresponding to the arc protrusions on the outer side of the first rotating shaft.

[0010] Preferably, the radius of the first pulley on the side close to the driving motor is larger than the radius of the first pulley on the side away from the driving motor, and the radius of the clutch wheel is larger than the radius of the first pulley on the side close to the driving motor.

[0014] 2. The present invention starts the first pulley, and the first pulley starts to drive the cam to rotate. The rotation of the cam pushes the limit column, and the limit column drives the clamping plate to rotate along the first limit rod. The clamping plate rotates around the fixed first limit rod, and the upper end of the clamping plate will be clamped toward the middle. When the cam rotates horizontally, the clamping plate is in a closed clamping state, thereby clamping the first motor shaft, and the tension spring is stretched by force. Due to the elastic characteristics of the tension spring, when clamping the first motor shaft, it can effectively avoid that the clamping force of the first motor shaft is too large, thereby causing indentations on the surface of the shaft body, thereby affecting the surface accuracy of the motor shaft, thereby affecting the normal use of the motor shaft.

The clamping plate 14 rotates around the fixed first limit rod 13 and the upper end of the clamping plate 14 will be clamped toward the middle. When the cam 12 rotates horizontally, the clamping plate 14 is in a closed clamping state, thereby clamping the first motor shaft 27. The tension spring 18 is stretched under force. Due to the elastic characteristics of the tension spring 18, when clamping the first motor shaft 27, it is possible to effectively avoid excessive clamping force on the first motor shaft 27, thereby causing indentations on the surface of the shaft body, thereby affecting the surface accuracy of the motor shaft, thereby affecting the normal use of the motor shaft. Otherwise, the clamping of the first motor shaft 27 is released and the first motor shaft 27 can be taken out.

[0026] Wherein, the pushing assembly includes a clutch wheel 19, the clutch wheel 19 is fixedly connected to the first rotating shaft 5, a third pulley 20 is provided on one side corresponding to the clutch wheel 19, a second belt 21 is provided between the clutch wheel 19 and the third pulley 20, the clutch wheel 19 and the third pulley 20 are connected through the second belt 21, a third rotating shaft 22 is fixedly connected to the middle of the third pulley 20, two threaded rods 23 are fixedly connected on both sides of the third rotating shaft 22, threaded sleeves 24 are threadedly sleeved on the outer sides of the two threaded rods 23, and the threaded sleeves 24 are fixedly connected to the mounting block 10, and the pushing assembly also includes a limit block 25, the limit block 25 is fixedly connected to one side of the mounting block 10, the inner sides of the limit block 25 are respectively in contact with the outer sides of the first pulley 6, the limit block 25 is slidably connected to the first rotating shaft 5, and the limit The internal through hole of the positioning block 25 is circular, and the through hole corresponds to the raised edge of the first rotating shaft 5. It is connected to the first rotating shaft 5 through the clutch wheel 19, and the pushing component is driven by the first rotating shaft 5, so that the first rotating shaft 5 drives the clutch wheel 19 to rotate, and the rotation of the clutch wheel 19 drives the third pulley 20 to rotate. The rotation of the third pulley 20 pushes the threaded sleeve 24 and the mounting block 10 away to change the clamping position, so that the clamping position will not block the processing, avoids the need to stop the processing during processing, and avoids the need to manually move the position and re-process the unprocessed area, thereby improving work efficiency and processing speed. At the same time, due to the different clamping forces, it can effectively avoid the sudden loss of clamping force when the clamping position is changed, and the clamping of the first motor shaft 27 is lost, causing the first motor shaft 27 to shift, which affects the processing of the first motor shaft 27.

[0027] Among them, a first motor shaft 27 is arranged in the middle of the clamping plate 14, and the radius of the first motor shaft 27 is smaller than the radius of the clamping plate 14. The clamping plate 14 is arranged corresponding to the first motor shaft 27. The radius of the clamping plate 14 is slightly larger than the width of the first motor shaft 275mm. A certain margin is left during clamping to enable better cooperation and better clamping of the first motor shaft 27.

[0028] Among them, a plurality of arc protrusions are arranged on the outside of the first rotating shaft 5, and the internal through holes of the first pulley 6 and the clutch wheel 19 are arranged corresponding to the arc protrusions on the outside of the first rotating shaft 5. The arc protrusions are arranged corresponding to the first pulley 6 and the clutch wheel 19 so that the first pulley 6 can be driven by the first rotating shaft 5. At the same time, because the protrusions cooperate with them, the first pulley 6 can move and slide on the outside of the first rotating shaft 5, so that its clamping position is not affected when it changes.

[0029] Among them, the radius of the first pulley 6 close to the driving motor 4 is greater than the radius of the first pulley 6 far away from the driving motor 4, the radius of the clutch wheel 19 is greater than the radius of the first pulley 6 close to the driving motor 4, when the cam 12 rotates horizontally, the clamping plate 14 is in a closed clamping state, and the stroke of the tension spring 18 becomes longer, and when the cam 12 rotates longitudinally, the clamping plate 14 is in an open state, and the stroke of the tension spring 18 becomes shorter. Since the radius of the first pulley 6 close to the driving motor 4 is greater than the radius of the first pulley 6 far away from the driving motor 4, the radius of the clutch wheel 19 is greater than the radius of the first pulley 6 close to the driving motor 4, the transmission ratio is controlled by setting the size of the radius, so that the clamping of the two first pulleys 6 will not be synchronously carried out to the clamping limit state, and the first pulley 6 close to the driving motor 4 will slightly loosen the clamping state. Due to the different clamping forces, it can effectively avoid the sudden loss of clamping force when the clamping position is changed, the clamping of the first motor shaft 27 is lost, the first motor shaft 27 is offset, and the processing of the first motor shaft 27 is affected.

[0030] Working principle:

[0031] By starting the first pulley 6, the first pulley 6 starts to drive the first rotating shaft 5 to rotate, the rotation of the first rotating shaft 5 drives the first pulley 6 to rotate, the rotation of the first pulley 6 drives the first belt 8 to rotate, the rotation of the first belt 8 drives the cam 12 to rotate, the rotation of the cam 12 drives the limiting column 15, the limiting column 15 drives the clamping plate 14 to rotate along the first limiting rod 13, the clamping plate 14 rotates around the fixed point first limiting rod 13, and the upper end of the clamping plate 14 will be clamped toward the middle, when the cam 12 rotates to the horizontal direction, the clamping plate 14 is in a closed clamping state, thereby clamping the first motor shaft 27, and the tension spring 18 is stretched by force. Due to the elastic characteristics of the tension spring 18, when the first motor shaft 27 is clamped, it can effectively avoid the clamping force of the first motor shaft 27 being too large, thereby causing indentations on the surface of the shaft body, thereby affecting the surface accuracy of the motor shaft, thereby affecting the normal use of the motor shaft, otherwise the clamping of the first motor shaft 27 is released, and the first motor shaft 27 can be taken out;

[0032] Since the radius of the first pulley 6 on the side close to the driving motor 4 is larger than the radius of the first pulley 6 on the side away from the driving motor 4, the radius of the clutch wheel 19 is larger than the radius of the first pulley 6 on the side close to the driving motor 4. By setting the size of the radius, the transmission ratio is controlled so that the clamping of the two first pulleys 6 will not be synchronously performed to the clamping limit state, and the first pulley 6 on the side close to the driving motor 4 will slightly loosen the clamping state. At this time, the clutch wheel 19 is connected to the first rotating shaft 5, and the pushing component is driven by the first rotating shaft 5, so that the first rotating shaft 5 drives the clutch wheel 19 to rotate, and the clutch wheel 19 rotates The third pulley 20 is driven to rotate, and the rotation of the third pulley 20 pushes the threaded sleeve 24 and the mounting block 10 away to change the clamping position, so that the clamping position will not block the processing, avoiding the need to stop the processing during processing, and manually move the position to re-process the unprocessed part, thereby improving work efficiency and processing speed. At the same time, due to the different clamping forces, it can effectively avoid the sudden loss of clamping force when the clamping position is changed, the loss of clamping of the first motor shaft 27, the displacement of the first motor shaft 27, and the impact on the processing of the first motor shaft 27.
