Description

Technical Field

[0001] The utility model relates to the field of stepping motors, and particularly relates to an adjustable base for a stepping motor. Background Art

[0002] The stepping motor and the base are important components in precision mechanical control. Their relationship is close and interdependent. The stepping motor is an actuator that can convert electrical pulses into angular displacements, while the base is the basic platform that supports the stepping motor and ensures its stable operation. In practical applications, the stepping motor is usually installed on the base. Through the fixation and support of the base, the stepping motor can accurately rotate by an angle to achieve precise position control.

[0003] However, in the prior art, since most of the bases of stepping motors can only fixedly install stepping motors of the same size, their practicability is relatively low. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an adjustable base for a stepping motor.

[0005] To solve the above technical problem, the technical solution of the utility model is: an adjustable base for a stepping motor, including a base body. An adjustment groove is opened inside the base body. Guide grooves are opened on both sides of the adjustment groove. Guide blocks are slidably connected inside the guide grooves. A moving block is fixedly connected to the front side of the guide block. A retaining ring is fixedly connected to the left side of the moving block. A retaining ring is movably connected inside the retaining ring. A lead screw is fixedly connected to the left side of the retaining ring. A threaded hole is opened on the left side of the base body.

[0006] Preferably, a connecting block is fixedly connected to the middle of the upper end of the moving block. A clamping hole is penetrated through the inside of the connecting block. Support blocks are fixedly connected to the edge positions of the upper end of the moving block. Bolts are arranged on the inner walls of the support blocks. A mounting block is movably connected inside the support blocks. A positioning seat is fixedly connected to the upper end of the mounting block.

[0007] Preferably, a mounting hole is opened inside the positioning seat. A fixing block is fixedly connected to the middle of the lower end of the positioning seat. Expansion rods are arranged on both sides of the fixing block. Springs are sleeved outside the expansion rods.

[0008] Preferably, the lead screw is movably connected to the moving block through the cooperation of the retaining ring and the retaining circle.

[0009] Preferably, the number of the mounting blocks is multiple groups, and they are symmetrically arranged about the midline of the positioning seat.

[0010] Preferably, the expansion rods are adapted to the clamping holes.

[0011] With the above technical solution, by rotating the lead screw, under the action of the threaded holes inside the base body, the moving block drives the positioning seat to move to the right, and the distance between the two positioning seats is shortened. Similarly, by simply rotating the lead screw in the reverse direction, the distance between the two positioning seats can be increased. During the movement of the moving block, the guiding block slides inside the guiding groove. With the cooperation of the guiding block and the guiding groove, the stability of the moving block during movement can be increased. Through components such as the lead screw, snap ring, retaining ring, and moving block, the distance between the two positioning seats can be adjusted, thereby meeting the installation requirements of stepping motors of different specifications and improving the practicality of the base at the same time.

[0012] With the above technical solution, by rotating the bolt and pushing the telescopic rod, the telescopic rod compresses the spring and slides out of the clamping hole. Pull the positioning seat upward, and the mounting block and the fixing block slide inside the connecting block and the fixing block to achieve the disassembly of the positioning seat. Similarly, slide the mounting block and the fixing block into the connecting block and the supporting block. When the telescopic rod reaches the position of the clamping hole, the spring rebounds to make the telescopic rod enter the clamping hole. Rotate the bolt in the reverse direction, and one end of the threaded bolt abuts against the mounting block to complete the installation of the positioning seat. Through the cooperation of the fixing block, telescopic rod, spring, mounting block, bolt, supporting block, and connecting block, the positioning seat can be quickly loaded and unloaded, thereby being able to replace positioning seats of different specifications and reducing the limitations of the base during use at the same time.

[0019] Embodiment 1

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: an adjustable stepping motor base, including a base main body 1. An adjustment groove 2 is opened inside the base main body 1. Guide grooves 3 are opened on both sides of the adjustment groove 2. A guide block 4 is slidably connected inside the guide groove 3. A moving block 5 is fixedly connected to the front side of the guide block 4. A snap ring 6 is fixedly connected to the left side of the moving block 5. A snap ring 7 is movably connected inside the snap ring 6. A lead screw 8 is fixedly connected to the left side of the snap ring 7. A threaded hole 9 is opened on the left side of the base main body 1. The lead screw 8 is movably connected to the moving block 5 through the snap ring 7 and the snap ring 6.

[0021] Specifically, when the lead screw 8 is rotated, under the action of the threaded hole 9 inside the base main body 1, the moving block 5 drives the positioning seat 15 to move to the right, and the distance between the two positioning seats 15 is shortened. Similarly, only by rotating the lead screw 8 in the reverse direction, the increase in the distance between the two positioning seats 15 can be achieved. During the movement of the moving block 5, the guide block 4 slides inside the guide groove 3. With the cooperation of the guide block 4 and the guide groove 3, the stability of the moving block 5 during movement can be increased. The distance between the two positioning seats 15 can be adjusted through components such as the lead screw 8, the snap ring 7, the snap ring 6, and the moving block 5, so as to meet the installation requirements of stepping motors of different specifications, and at the same time improve the practicability of the base. Finally, the stepping motor is installed through the installation holes 16 on the positioning seat 15.

[0022] Embodiment 2

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: an adjustable stepping motor base. A connecting block 10 is fixedly connected to the middle of the upper end of the moving block 5. A card hole 11 is penetrated inside the connecting block 10. Support blocks 12 are fixedly connected to the edge positions of the upper end of the moving block 5. Bolts 13 are arranged on the inner walls of the support blocks 12. An installation block 14 is movably connected inside the support blocks 12. A positioning seat 15 is fixedly connected to the upper end of the installation block 14. An installation hole 16 is opened inside the positioning seat 15. A fixing block 17 is fixedly connected to the middle of the lower end of the positioning seat 15. Expansion rods 18 are arranged on both sides of the fixing block 17. Springs 19 are sleeved outside the expansion rods 18. The number of installation blocks 14 is multiple, and they are symmetrically arranged about the center line of the positioning seat 15. The expansion rods 18 are adapted to the card holes 11.

[0024] Specifically, rotate the bolt 13 and push the telescopic rod 18. The telescopic rod 18 compresses the spring 19 and slides out of the clamping hole 11. Pull the positioning seat 15 upward. The mounting block 14 and the fixing block 17 slide within the connecting block 10 and the fixing block 17 to achieve the disassembly of the positioning seat 15. Similarly, slide the mounting block 14 and the fixing block 17 into the connecting block 10 and the support block 12. When the telescopic rod 18 reaches the position of the clamping hole 11, the spring 19 rebounds to make the telescopic rod 18 enter the clamping hole 11. Rotate the bolt 13 in the reverse direction, and one end of the threaded bolt abuts against the mounting block 14 to complete the installation of the positioning seat 15. Through the cooperation of the fixing block 17, the telescopic rod 18, the spring 19, the mounting block 14 with the bolt 13, the support block 12, and the connecting block 10, the positioning seat 15 can be quickly loaded and unloaded, and thus different specifications of the positioning seat 15 can be replaced. At the same time, the limitations of the base during use can also be reduced.

[0025] Working principle: When this stepping motor base is in use, first, replace different positioning seats 15 according to the specifications of the stepping motor. The specific operation is as follows: rotate the bolt 13 and push the telescopic rod 18. The telescopic rod 18 compresses the spring 19 and slides out of the clamping hole 11. Pull the positioning seat 15 upward. The mounting block 14 and the fixing block 17 slide within the connecting block 10 and the fixing block 17 to achieve the disassembly of the positioning seat 15. Similarly, slide the mounting block 14 and the fixing block 17 into the connecting block 10 and the support block 12. When the telescopic rod 18 reaches the position of the clamping hole 11, the spring 19 rebounds to make the telescopic rod 18 enter the clamping hole 11. Rotate the bolt 13 in the reverse direction, and one end of the threaded bolt abuts against the mounting block 14 to complete the installation of the positioning seat 15. Through the cooperation of the fixing block 17, the telescopic rod 18, the spring 19, the mounting block 14 with the bolt 13, the support block 12, and the connecting block 10, the positioning seat 15 can be quickly loaded and unloaded, and thus different specifications of the positioning seat 15 can be replaced. At the same time, the limitations of the base during use can also be reduced. Then, adjust the distance between the two groups of positioning seats 15. The specific operation is as follows: rotate the lead screw 8. Under the action of the threaded hole 9 inside the base body 1, the moving block 5 drives the positioning seat 15 to move to the right, and the distance between the two groups of positioning seats 15 is shortened. Similarly, only by rotating the lead screw 8 in the reverse direction can the distance between the two groups of positioning seats 15 be increased. During the movement of the moving block 5, the guiding block 4 slides inside the guiding groove 3. With the cooperation of the guiding block 4 and the guiding groove 3, the stability of the moving block 5 during movement can be increased. Through components such as the lead screw 8, the snap ring 7, the snap ring 6, and the moving block 5, the distance between the two groups of positioning seats 15 can be adjusted, and thus the installation requirements of different specifications of stepping motors can be met. At the same time, the practicability of the base can also be improved. Finally, install the stepping motor through the mounting hole 16 on the positioning seat 15.
