Description

Technical Field

[0001] The utility model relates to a motor shaft moving mechanism. Background Art

[0002] The rotating shaft is an important part in the motor. As the link for electromechanical energy conversion between the motor and the equipment, the motor shaft supports the rotating parts, transmits torque and determines the relative position of the rotating parts to the stator.

In addition, the existing automatic crimping device can only crimp one bushing onto one motor shaft at a time, so the processing efficiency is also low, which needs further improvement.

[0020] The end of the pressing block 54 is provided with a plurality of pressing grooves 541 which are evenly spaced from front to back. Correspondingly, the telescopic end of the assembly cylinder 55 is also fixed with the same number of pressing rods 56.

[0022] A positioning cylinder 6 is also provided on the left side of the fixed support plate 2, and the positioning cylinder 6 is fixed on the top of the base plate 1. A laterally distributed positioning strip 7 is also provided above the fixed support plate 2. The telescopic end of the positioning cylinder 6 is laterally arranged to the right and parallel to the length direction of the first limiting groove 204 and fixed on the positioning strip 7.

[0023] Working principle:

[0024] As needed, the telescopic end of the alignment cylinder 6 is driven to extend outward to drive the alignment bar 7 to move right to the specified position; then the telescopic end of the lifting cylinder 43 in the material moving assembly 4 is driven to retract inward to drive the movable support plate 44 to move vertically downward to the bottom of the rectangular notch groove 202, and at the same time, the telescopic end of the moving cylinder 42 is driven to retract inward or extend outward to drive the movable support plate 44 to move forward with the help of the moving frame 41 and the lifting cylinder 43, until the frontmost second groove limit groove 441 on the movable support plate 44 is located below the frontmost first limit groove 204.

[0025] Next, take a motor shaft and place it horizontally into a first limiting groove 204 at the front, then take a shaft sleeve and preliminarily sleeve it on the outside of the right end step of the motor shaft, and at the same time make the left end of the motor shaft against the alignment bar 7 to complete the preliminary positioning; then drive the telescopic end of the lifting cylinder 43 to extend outward to drive the movable support plate 44 to move upward in the same way, and then lift the motor shaft upward and leave the first limiting groove 204 at the front. At this time, the movable support plate 44 is located above the rectangular notch groove 202.

[0026] Next, the telescopic end of the moving cylinder 42 is driven to extend outward or retract inward to drive the moving support plate 44 to move backward in the same way until the motor shaft is located above the second first limit groove 204 from the front to the back, and then the telescopic end of the lifting cylinder 43 is driven to retract inward to drive the motor shaft to move downward with the help of the moving support plate 44 until the above-mentioned motor shaft is horizontally inserted into the second first limit groove 204 from the front to the back, thereby moving the above-mentioned motor shaft backward by the distance of a first limit groove 204.

[0027] Next, according to the same method, another motor shaft is placed in the frontmost first limit slot 204 and the sleeve is placed and initially positioned. Then, according to the same steps, the material moving assembly 4 is operated to make both motor shafts move backwards by the distance of the first limit slot 204 at the same time, and so on.

[0028] When several motor shafts counted from the back to the front move to the bottom of the pressing block 54 in the assembly component 5, and each pressing groove 541 located on the pressing block 54 is located directly above a corresponding motor shaft, the telescopic end of the positioning cylinder 53 is driven to extend outward to drive the pressing block 54 to move downward until each pressing groove 541 is pressed against a corresponding motor shaft, and then the telescopic end of the assembly cylinder 55 is driven to extend outward to drive each pressing rod 56 to move to the left, thereby making the end of each pressing rod 56 squeeze the sleeve on the corresponding motor shaft to the left until each sleeve is completely sleeved on the step portion at the right end of the motor shaft, thereby completing the assembly process of several sleeves at the same time.

[0029] After the assembly is completed, the telescopic end of the assembly cylinder 55 is driven to retract inward to drive each pressing rod 56 to move right and reset, and at the same time, the telescopic end of the positioning cylinder 53 is driven to retract inward to drive the pressing block 54 to move up and away from each motor shaft; finally, the material moving component 4 is operated according to the same steps to make each motor shaft continue to move backward at equal intervals; when the rearmost motor shaft is moved from the bottom of the material moving component 4 to the rear side of the rearmost limit bar 203, the above-mentioned motor shaft will roll along the material guide arc surface 205 to the material guide inclined surface 201, and then continue to roll backward along the slope of the material guide inclined surface 201, and a material receiving box is set below the rear side edge of the material guide inclined surface 201, and the motor shaft after rolling away from the material guide inclined surface 201 will automatically fall into the material receiving box to realize automatic discharging and collection.

[0030] The utility model can automatically complete the movement and discharging of the motor shaft without manual operation, thereby reducing labor intensity and reducing labor costs; and can automatically and simultaneously press-connect multiple sleeves to the corresponding number of motor shafts at one time with the help of the assembly component 5, thereby improving processing efficiency.
