Description

Technical Field

[0001] This utility model relates to the field of stepper driver technology, and in particular to a driving auxiliary device for a stepper driver. Background Technology

[0002] A stepper motor driver is an actuator that converts electrical pulses into angular displacement. When a stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in a set direction. Its rotation is done step by step at fixed angles. The amount of angular displacement can be controlled by controlling the number of pulses, thereby achieving accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, thereby achieving speed regulation and positioning.

[0003] The existing stepper drive unit is fixed to the equipment with screws. When it is necessary to replace the stepper die with a different size, the screws fastening the drive motor behind the stepper die must be loosened and manually adjusted. After each adjustment, the machine must be tested to check whether the adjustment position is correct, which wastes a lot of time, affects production efficiency, reduces replenishment efficiency, and increases equipment labor costs and packaging material consumption.

[0004] Therefore, we propose a driving auxiliary device for a stepper driver. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a driving auxiliary device for a stepper driver. When it is necessary to change the stepper mold, the position of the drive motor can be quickly adjusted, saving the time of mold change, avoiding material waste caused by frequent trial runs, and reducing workshop labor costs.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a driving auxiliary device for a stepper driver, comprising a slide rail, a slider, a connecting plate, a base plate, a frame, a drive motor, a support seat, a screw, a handwheel, and a locking bolt. There are two slide rails arranged in parallel. The slider is slidably mounted on the slide rail. The connecting plate is fixedly mounted between two adjacent sliders. The base plate is fixedly mounted on one side of the two connecting plates. The frame is fixedly mounted on the base plate. The drive motor is fixedly mounted on the frame. The support seat is disposed on one side of the slide rail. The screw is threadedly connected to the support seat. The handwheel is fixedly mounted on one end of the screw, and the other end of the screw is rotatably connected to one of the connecting plates. One of the connecting plates has a T-shaped groove on one side, one end of the screw extends into the T-shaped groove, and the locking bolt is threaded onto one side of the connecting plate, with one end of the locking bolt extending into the T-shaped groove.

[0007] As a preferred embodiment of this utility model, the slide rail has first mounting holes at both ends.

[0008] In a preferred embodiment of this invention, the connecting plate and the slider are fixedly installed by a first bolt.

[0009] In a preferred embodiment of this utility model, the connecting plate and the base plate are fixedly installed by a second bolt.

[0010] In a preferred embodiment of this utility model, the base plate and the frame are fixedly installed by a third bolt.

[0011] In a preferred embodiment of this invention, the frame and the drive motor are fixedly installed by a fourth bolt.

[0012] As a preferred embodiment of this utility model, the support base has second mounting holes at both ends.

[0013] Compared with the prior art, the beneficial effects that this utility model can achieve are: With the arrangement of slide rails, sliders, connecting plates, base plates, frames, drive motors, support seats, screws, and handwheels, when it is necessary to change the stepper mold, simply remove the screws that fix the drive motor, turn the handwheel to drive the screw to rotate, and the screw will drive the connecting plate to slide along the slide rail. This allows for quick adjustment of the drive motor's position, saving time when changing molds, avoiding material waste caused by frequent trial runs, and reducing workshop labor costs.

[0014] By setting the locking bolt, once the position of the drive motor is properly adjusted, the locking bolt can be manually tightened to make it press against the screw rod for fixation, thereby preventing the screw rod from rotating and locking the screw rod to ensure stability after adjustment.

[0018] Please refer to Figure 1-3 As shown, this utility model provides a driving auxiliary device for a stepper driver, including a slide rail 1, a slider 2, a connecting plate 3, a base plate 4, a frame 5, a drive motor 6, a support base 7, a screw 8, a handwheel 9, and a locking bolt 10. There are two slide rails 1 arranged in parallel. Each end of one slide rail 1 has a first mounting hole 11, through which the slide rail 1 is installed and fixed. The slider 2 is slidably mounted on the slide rail 1. The connecting plate 3 is fixedly mounted between two adjacent sliders 2. The base plate 4 is fixedly mounted on one side of the two connecting plates 3. The frame 5 is fixedly mounted on the base plate 4. The drive motor 6 is fixedly mounted on the frame 5. The support base 7 is located on one side of the slide rail 1. Each end of the support base 7 has a second mounting hole 71, through which the support base 7 is installed and fixed. The screw 8 is threaded onto the support base 7 and is arranged parallel to the slide rail 1. The handwheel 9 is fixedly installed at one end of the screw 8, and the other end of the screw 8 is rotatably connected to one of the connecting plates 3. Through the arrangement of the slide rail 1, slider 2, connecting plate 3, base plate 4, frame 5, drive motor 6, support base 7, screw 8, and handwheel 9, when it is necessary to change the stepper mold, it is only necessary to remove the screws fixing the drive motor 6 and turn the handwheel 9 to make the handwheel 9 drive the screw 8 to rotate, so that the screw 8 drives the connecting plate 3 to slide along the slide rail 1. The position of the drive motor 6 can be quickly adjusted, saving the time of changing the mold, avoiding the waste of materials caused by frequent trial runs, and reducing the workshop's labor costs.

[0019] Furthermore, one of the connecting plates 3 has a T-shaped groove 31 on one side. One end of the screw 8 extends into the T-shaped groove 31. The locking bolt 10 is threaded onto one side of the connecting plate 3, and one end of the locking bolt 10 extends into the T-shaped groove 31. With the locking bolt 10, when the position of the drive motor 6 is properly adjusted, the locking bolt 10 can be manually tightened to make the locking bolt 10 press against the screw 8 for fixation, thereby preventing the screw 8 from rotating and locking the screw 8 to ensure the stability after adjustment.

[0020] Specifically, the connecting plate 3 and the slider 2 are fixedly installed by the first bolt 32, the connecting plate 3 and the base plate 4 are fixedly installed by the second bolt 33, the base plate 4 and the frame 5 are fixedly installed by the third bolt 41, and the frame 5 and the drive motor 6 are fixedly installed by the fourth bolt 51. The arrangement of the first bolt 32, the second bolt 33 and the third bolt 41 allows the slider 2, the connecting plate 3, the base plate 4, the frame 5 and the drive motor 6 to be freely disassembled.

[0021] The implementation principle of this utility model is as follows: When it is necessary to replace the stepper mold, simply remove the screws that fix the drive motor 6, turn the handwheel 9 to make the screw 8 rotate, and make the screw 8 drive the connecting plate 3 to slide along the slide rail 1. The position of the drive motor 6 can be quickly adjusted. After the position of the drive motor 6 is adjusted properly, the locking bolt 10 can be manually tightened to make the locking bolt 10 press against the screw 8 for fixation, thereby preventing the screw 8 from rotating and locking the screw 8. This saves time for changing molds, avoids material waste caused by frequent trial runs, and reduces workshop labor costs.
