Description

Technical Field

[0001] This utility model relates to the field of stepper motor drivers, and in particular to a protective device for stepper motor drivers. Background Technology

[0002] A stepper motor driver is an actuator that converts electrical pulses into angular displacement. A stepper motor and a stepper motor driver constitute a stepper motor drive system. The performance of a stepper motor drive system depends not only on the performance of the stepper motor itself, but also on the quality of the stepper motor driver. Research on stepper motor drivers has been carried out almost simultaneously with research on stepper motors.

[0003] As the core component for controlling the precise operation of stepper motors, the performance of the stepper motor driver directly affects the operating accuracy and stability of the equipment.

[0004] Currently, most stepper motor drivers are directly fixed to the equipment mounting plate or chassis with bolts. The installation process requires tightening each bolt one by one, which is time-consuming and labor-intensive. Especially in the case of batch installation or emergency replacement, the efficiency is extremely low. When the equipment is bumped during transportation or vibrates during operation, the driver is prone to damage to the internal precision circuit components due to stress concentration, which affects the service life. Therefore, a protective device for stepper motor drivers is proposed to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4This utility model provides an embodiment of a protective device for a stepper motor driver, comprising a mounting frame 1, four sets of mounting blocks 2 fixedly mounted on the top of the mounting frame 1, placement plates 3 on both sides of the top of the mounting frame 1, the bottom of the placement plates 3 and the outer side of the mounting blocks 2 fixedly mounted, four sets of clamping blocks 4 on the top of the mounting frame 1, and moving components 5 for driving the clamping blocks 4 to move on both sides of the top of the mounting frame 1, and a stepper motor driver body 6 on both sides of the top of the mounting frame 1. First, the stepper motor driver body 6 can be placed on the placement plates 3, and then the clamping blocks 4 can be driven to move inward simultaneously by the moving components 5. The inward movement of the clamping blocks 4 can limit and clamp the stepper motor driver body 6.

[0031] Reference Figure 1-4 The moving component 5 includes two sets of fixing blocks 51. The bottom of the fixing block 51 and the top of the mounting block 2 are fixedly installed. A gear 52 is provided on the top of the fixing block 51. Toothed plates 53 are provided on both sides of the top of the fixing block 51. The toothed plates 53 mesh with the gear 52. A pull block 54 is fixedly installed on the outer side of the toothed plate 53. The top of the pull block 54 and the bottom of the clamping block 4 are fixedly installed. Through the mutual cooperation of the fixing block 51, gear 52, toothed plate 53 and pull block 54, when the stepper motor driver body 6 is placed on the placement plate 3, the gear 52 can be rotated. The rotation of the gear 52 drives the toothed plate 53 to move inward. The inward movement of the toothed plate 53 drives the pull block 54 to move inward. The inward movement of the pull block 54 drives the clamping block 4 to move inward. The inward movement of the clamping block 4 will contact the stepper motor driver body 6, thereby driving the stepper motor. The stepper motor driver body 6 is limited to prevent it from shaking during transportation. A dual-axis motor 55 is fixedly installed at the bottom of the inner wall of the mounting bracket 1. Worms 56 are fixedly installed at both ends of the dual-axis motor 55. A connecting rod 57 is fixedly installed at the bottom of the gear 52. The bottom of the connecting rod 57 extends through to the bottom of the fixing block 51. A worm wheel 58 is fixedly installed on the surface of the connecting rod 57. The worm wheel 58 meshes with the worm 56. Through the mutual cooperation of the dual-axis motor 55, worm 56, connecting rod 57 and worm wheel 58, when the dual-axis motor 55 is started, the two ends of the dual-axis motor 55 drive the worm 56 to rotate. The rotation of the worm 56 drives the worm wheel 58 to rotate. The rotation of the worm wheel 58 drives the connecting rod 57 to rotate. The rotation of the connecting rod 57 drives the gear 52 to rotate, thereby causing the clamping block 4 to move inward to limit the stepper motor driver body 6.

[0032] Reference Figure 1-4A rectangular block 7 is rotatably mounted on the outer end of the worm gear 56. The top of the rectangular block 7 and the bottom of the fixing block 51 are fixedly mounted. The rectangular block 7 limits the movement of the worm gear 56, preventing it from wobbling during rotation and thus preventing it from continuously meshing with the worm wheel 58. A slider 8 is fixedly mounted on the top of the placement plate 3. A sliding sleeve 9 is slidably mounted on the surface of the slider 8. The top of the sliding sleeve 9 and the bottom of the clamping block 4 are fixedly mounted. The slider 8 and the sliding sleeve 9 cooperate to limit the movement of the clamping block 4, preventing it from wobbling during movement and thus preventing it from moving linearly and limiting the movement of the stepper motor driver body 6. Both sides of the top of the mounting bracket 1 are provided with A partition 10 is provided, with its bottom fixedly installed on the bottom of the placement plate 3. The top of the partition 10 contacts the top of the stepper motor driver body 6. The partition 10 allows the stepper motor driver body 6 to be placed on it, increasing the contact area between the stepper motor driver body 6 and the placement plate 3, thereby improving the stability of the stepper motor driver body 6 during placement. A rubber block 11 is fixedly installed on the inner side of the clamping block 4, with its inner side contacting the front and rear sides of the stepper motor driver body 6. The rubber block 11 protects the stepper motor driver body 6 and prevents the clamping block 4 from damaging it.

[0033] Working principle: When the stepper motor driver body 6 needs to be transported, to prevent the stepper motor driver body 6 from shaking during transportation, the mounting bracket 1 and the carriage can be fixed with bolts. Then, the stepper motor driver body 6 is placed on the partition plate 10 of the plate 3. Then, the dual-axis motor 55 can be started. The two ends of the dual-axis motor 55 drive the worm gear 56 to rotate. The rotation of the worm gear 56 drives the worm wheel 58 to rotate. The rotation of the worm wheel 58 drives the connecting rod 57 to rotate. The rotation of the connecting rod 57 drives the gear 52 to rotate. The rotation of the gear 52 drives the... The moving toothed plate 53 moves inward, which in turn drives the pull block 54 to move inward. The pull block 54 moves inward, which in turn drives the clamping block 4 to move inward. The clamping block 4 moves inward, which in turn drives the rubber block 11 to move inward. The rubber block 11 moves inward and comes into contact with the stepper motor driver body 6, thereby limiting the stepper motor driver body 6 and preventing it from shaking during transportation. When the stepper motor driver body 6 is transported to the position, the above reverse steps can be repeated to remove it.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
