Technical Field

[0001] The invention relates to the technical field of motor spindle machining, and more specifically to a positioning device for motor spindle machining. Background Art

[0002] The motor spindle is the rotating part that outputs power when the motor is running, and it is also a key part connected to the transmission system. The positioning device of the motor spindle processing is an important part to ensure that the spindle can be accurately and stably positioned at a specific position during the processing. Usually a mechanical positioning device is used: this positioning device usually uses a mechanical structure to achieve the positioning of the spindle. For example, mechanical parts such as positioning pins and positioning blocks are used to lock the spindle in a specific position.

[0003] There are some problems in the use of the existing positioning device for motor spindle processing, as follows:

[0015] Technical effects and advantages of the present invention:

[0016] The present invention connects the bottom of the machine tool output shaft positioning plate with the output end of the machine tool during the processing of the motor spindle. During the positioning of the motor spindle, the spindle is first inserted into the clamping assembly, and then the position of the spindle is adjusted so that the middle part of the spindle is located on the inner side of the positioning disc. Then, the second servo motor drives the first gear to rotate, and then drives the second gear to rotate, and then drives the third transmission rod to rotate, and then drives the third gear located at both ends of the third transmission rod to rotate. The arc toothed belt is driven to rotate along the center of the pushing disc through the cooperation of the third gear and the arc toothed belt, and then drives the pushing disc to rotate relative to the positioning disc, and then drives the arc push groove to rotate. Through the rotation of the arc push groove and under the positioning of the waist groove and the guide rod, the clamping guide rod is pushed to move closer to the inside, and then drives the clamping block to move closer to the inside, so as to fix the motor spindle, thereby achieving the purpose of fixing the motor spindle. Moreover, since the number of the clamping blocks is two groups, the motor spindle is fixed more stably.

[0017] The present invention adopts the shape of the first slider assembly and the second slider assembly to consist of two convex sliders in vertical directions, and the pushing disc can rotate relative to the first slider assembly and the second slider assembly under the limitation of the convex groove on the inner side of the positioning sleeve, thereby ensuring the rotation of the pushing disc relative to the positioning disc, so that the clamping assembly can clamp the motor spindle, and the clamping assembly can be positioned in the positioning sleeve.

[0018] The present invention drives the hydraulic rod to extend through the operation of the hydraulic cylinder, thereby causing the arc-shaped clamping block to move away from the arc-shaped positioning groove, and the distance away from the arc-shaped positioning sleeve is sufficient for the positioning sleeve to rotate, and then the first servo motor drives the positioning sleeve to rotate, and under the positioning of the positioning rotating shaft by the U-shaped positioning frame, the positioning rotating shaft does not rotate relative to the positioning sleeve, and because the connection position between the positioning rotating shaft and the positioning sleeve is located in the middle of the positioning sleeve, the first bevel gear will rotate along the center of the first mountain-shaped gear during the rotation of the positioning sleeve, which is beneficial to achieve the adjustment of the position of the clamping assembly during the process of driving the positioning sleeve to rotate by the first servo motor, thereby achieving the purpose of adjusting the processing end of the motor spindle.

[0019] The present invention drives the first bevel gear to rotate through the cooperation between the first bevel gear and the first mountain-shaped gear teeth, and then drives the second transmission rod to rotate, and then drives the third transmission gear assembly to rotate. Since the shape of the third transmission gear assembly is the same as that of the second transmission gear assembly, the two second transmission toothed belts outside the third transmission gear assembly are driven to drive the two second transmission gear assemblies to rotate, and then the first transmission wheel assembly is driven to rotate under the transmission of the second transmission toothed belt, and then the second mountain-shaped gear is driven to rotate, and then the second bevel gear is driven to rotate under the transmission of the teeth of the second mountain-shaped gear and the second bevel gear, and then the first transmission shaft is driven to rotate, so that the first transmission shaft rotates and then drives the second positioning circular plate and The first gear shaft rotates, which in turn drives the first transmission toothed belt to rotate, and then drives the first slider assembly to move toward the other end of the positioning sleeve through the teeth on the outer side of the first transmission toothed belt, and then drives the clamping assembly to move to the other end, so that the motor spindle gradually approaches the other end of the positioning sleeve during the process of the first servo motor driving the positioning sleeve to rotate, so that the other end of the motor spindle is exposed, and then the hydraulic cylinder drives the hydraulic rod to contract, so that the arc-shaped clamping block and the arc-shaped positioning groove are close to each other, and the motor spindle can be processed by the processing equipment, avoiding the need to first process one end of the spindle during the processing of the motor spindle, then remove the spindle and perform a secondary fixation, so that the processing efficiency of the motor spindle is effectively increased.

[0020] In the process of rotating the positioning sleeve 180 degrees, the gear ratio of the first mountain-shaped gear to the first bevel gear and the gear ratio of the second bevel gear to the second mountain-shaped gear are used to enable the conveying component to rotate and drive the clamping component to move from one end of the inner side of the positioning sleeve to the other end.

Through the rotation of the arc-shaped push groove 3014 and under the positioning of the waist-shaped groove 302 and the guide rod 303, the clamping guide rod 309 is pushed to move closer to the inside and then drives the clamping block 3010 to move closer to the inside to fix the motor spindle, thereby achieving the purpose of fixing the motor spindle, and because the number of the clamping blocks 3010 is two groups, the motor spindle is fixed more stably; and the shape of the first slider assembly 3012 and the second slider assembly 3016 is composed of two convex sliders in vertical directions, and under the limitation of the convex groove on the inner side of the positioning sleeve 201, the pushing disk 3011 can rotate relative to the first slider assembly 3012 and the second slider assembly 3016, ensuring the rotation of the pushing disk 3011 relative to the positioning disk 301, so that the clamping assembly 3 can clamp the motor spindle, and the clamping assembly 3 can be positioned in the positioning sleeve 201;

[0043] After the processing is completed at one end of the motor spindle, the hydraulic cylinder 106 is first used to drive the hydraulic rod 107 to extend, thereby moving the arc block 202 away from the arc positioning groove 105, and the distance away is sufficient for the positioning sleeve 201 to rotate, and then the first servo motor 205 is used to drive the positioning sleeve 201 to rotate 180 degrees, and under the positioning of the positioning rotating shaft 20310 by the U-shaped positioning frame 204, the positioning rotating shaft 20310 does not rotate relative to the positioning sleeve 201, and because the connection position between the positioning rotating shaft 20310 and the positioning sleeve 201 is located in the middle of the positioning sleeve 201, the positioning sleeve 201 rotates. During the process, the first bevel gear 2038 will rotate along the center of the first mountain-shaped gear 2039. The cooperation between the teeth of the first bevel gear 2038 and the first mountain-shaped gear 2039 drives the first bevel gear 2038 to rotate, and then drives the second transmission rod 2037 to rotate, and then drives the third transmission gear assembly 2036 to rotate. Since the shape of the third transmission gear assembly 2036 is the same as that of the second transmission gear assembly 2035, the two second transmission toothed belts 2034 outside the third transmission gear assembly 2036 are driven to drive the two second transmission gear assemblies 2035 to rotate, and then the second transmission gear assembly 2036 is driven to rotate. The first transmission wheel assembly 2033 is driven to rotate under the transmission of the belt 2034, and then the second mountain-shaped gear 20312 is driven to rotate, and then the second bevel gear 20311 is driven to rotate under the transmission of the teeth of the second mountain-shaped gear 20312 and the second bevel gear 20311, and then the first transmission shaft 2032 is driven to rotate, so that the first transmission shaft 2032 rotates and then drives the second positioning circular plate 203101 and the first gear shaft 203102 to rotate, and then drives the first transmission toothed belt 203103 to rotate, and then drives the first slider assembly 3012 to the positioning sleeve 20 through the teeth on the outer side of the first transmission toothed belt 203103. 1 moves, and then drives the clamping assembly 3 to move to the other end, so that the motor spindle gradually approaches the other end of the positioning sleeve 201 during the process of the first servo motor 205 driving the positioning sleeve 201 to rotate, so that the other end of the motor spindle is exposed, and then the hydraulic cylinder 106 drives the hydraulic rod 107 to contract, so that the arc-shaped clamping block 202 and the arc-shaped positioning groove 105 are close to each other, and the motor spindle can be processed by the processing equipment, avoiding the process of first processing one end of the spindle during the processing of the motor spindle, and then removing the spindle for secondary fixation, so that the processing efficiency of the motor spindle is effectively increased.
