Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a clamping positioning device for producing motor shafts. Background Art

[0002] In the current production process of motor shaft polishing, the clamping and positioning of the motor shaft is a crucial link. Traditional motor shaft clamping and positioning devices mostly use a motor installed on the base, which drives the screw to rotate through the motor, so that the two clamps threaded on the screw move toward the middle at the same time, thereby clamping the motor shaft. This clamping method can fix the motor shaft to a certain extent, but with the continuous improvement of production requirements, the clamping and positioning devices in the prior art still have certain defects that need to be improved;

[0003] China's authorized utility model patent (publication number: CN220408098U) discloses a clamping and positioning device for the production of motor shafts. However, when the device is in use, the motor shafts may have slight differences in size during the production process. The traditional double-chuck clamping method is difficult to adapt to such changes. When the motor shaft size is too large or too small, the gap between the chuck and the shaft will cause the clamping stability to decrease, thereby affecting the subsequent production process and reducing its adaptability. Therefore, a clamping and positioning device for the production of motor shafts is proposed to overcome the above-mentioned defects. Utility Model Content

After the motor shaft body 11 is limited and fixed at the limiting part at the bottom, the hydraulic telescopic rod 8 is started to move according to the height of the motor shaft body 11 so that the positioning clamping mechanism is located at the top of the motor shaft body 11, and the positioning clamping mechanism is located at the top of the motor shaft body 11. The structure limits the top, and the starting motor drives the threaded rod to rotate. The rotation of the threaded rod drives the left slider and the right slider to move in opposite directions, so that the left chuck and the right chuck clamp and position the top of the motor shaft. A motor shaft body 11 is arranged between the positioning and clamping mechanism and the limiting part. Four first discharge grooves 103 are opened inside the base 1. The four first discharge grooves 103 are respectively located at the bottom of the corresponding limiting grooves 101 and are connected with the limiting grooves 101. The positioning rod 3 moves in the positioning groove 102, driving the limiting plate 2 to push the debris to the corners inside the limiting groove 101, and the debris is discharged from the first discharge groove 103. Limiting grooves 101 are opened all around the base 1, and a second motor 12 is installed at the bottom of the base 1.

[0026] The limiting part has a limiting plate 2 and a positioning rod 3, the limiting plate 2 is slidably fitted in the limiting groove 101, and positioning grooves 102 are provided around the base 1. The positioning groove 102 is located at the top of the limiting groove 101 and is connected to the limiting groove 101. A positioning rod 3 is installed on the top of the limiting plate 2, and the positioning rod 3 is slidably fitted in the positioning groove 102. A connecting rod 4 is installed on the top of the positioning rod 3, and a guide rod 5 is installed at the bottom of the connecting rod 4. A clamping block 6 is installed at one end of the connecting rod 4. When the motor shaft body 11 is fixed, the motor shaft body 11 is placed between the limiting part and the positioning clamping mechanism. At this time, the second motor 12 is started to drive the chassis 7 The rotation causes the guide rod 5 to slide along the guide groove 701 and drives the connecting rod 4 to move. At this time, the connecting rod 4 drives the positioning rod 3 to slide along the positioning groove 102. The positioning rod 3 is limited by the sliding of the limiting plate 2 in the limiting groove 101 to prevent it from moving out of the positioning groove 102.
