Description

Technical Field

[0001] This application relates to the field of support platform technology, and in particular to a stepper motor driven lifting support platform device. Background Technology

[0002] A stepper motor is an actuator that converts electrical pulse signals into angular or linear displacement. Its working principle is based on electromagnetism; inside the motor are a set of coils and magnetic poles arranged in a specific pattern. When an electrical pulse signal is applied to the motor, the current in the coils generates a magnetic field, which interacts with the magnetic poles, causing the motor to rotate by a fixed angle, called the step angle. By continuously applying electrical pulse signals, a stepper motor can precisely control its rotation angle and displacement, achieving complex mechanical movements.

[0003] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks:

[0004] When installing a stepper motor onto a support platform, positioning is often achieved by locking the four corners of the stepper motor base with bolts. This can lead to incompatibility when fixing stepper motor bases of different lengths and widths. Furthermore, positioning with bolts requires tightening the bolts sequentially, which prevents rapid positioning.

[0005] Therefore, in response to the above problems, the applicant provides a stepper motor driven lifting support platform device. Utility Model Content

[0006] In order to solve the problems mentioned in the background art, this application provides a stepper motor driven lifting support platform device.

[0007] This application provides a stepper motor driven lifting support platform device, which adopts the following technical solution:

[0008] A stepper motor driven lifting support platform device includes a support platform with a locking mechanism on it. The locking mechanism includes an "I"-shaped slider, a first forward and reverse threaded rod, a locking block, and a sliding plate. The "I"-shaped slider is threadedly connected to two first forward and reverse threaded rods. The top of each of the two first forward and reverse threaded rods is fixedly connected to a locking block. The locking block is slidably connected to a sliding plate. Both ends of the sliding plate are fixedly connected to a connecting frame. The connecting frame is threadedly connected to a second forward and reverse threaded rod.

[0009] Optionally, it also includes a support platform, on which an "I"-shaped groove is provided, and two "I"-shaped sliders are slidably connected to the "I"-shaped groove. A through hole is provided through the support platform, and a forward and reverse threaded rod is threadedly connected to the through hole. A crank handle is fixedly connected to one end of the forward and reverse threaded rod.

[0010] Optionally, a stepper motor base is placed on the top of the support platform, a sliding groove is provided on the card block, a slider is fixedly connected to one side of the sliding plate, and two sliding grooves are slidably connected in the slider.

[0011] Optionally, a fixing ring is fixedly connected to one side of the support platform, and a stud is threaded onto the fixing ring and abuts against the outer circumferential wall of the forward and reverse threaded rod.

[0012] Optionally, four brackets are fixedly connected to the top surface of the support platform. Two brackets form a group, and each group of brackets is rotatably connected to a forward and reverse threaded rod. One end of the forward and reverse threaded rod is fixedly connected to a crank handle.

[0013] Optionally, each of the two brackets is fixedly connected to a second fixing ring, and the second fixing ring is threadedly connected to a second stud and abuts against a second reversible threaded rod.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. This utility model, through the setting of a card and mechanism, limits the lateral and longitudinal positions of the stepper motor base, thereby clamping and fixing the stepper motor base to the support platform. By locking the first forward and reverse threaded rod one with stud one and locking the second forward and reverse threaded rod two with stud two, the card block after lateral positioning and the sliding plate after longitudinal positioning can be locked, giving the stepper motor base the advantage of quick positioning.

[0016] 2. This utility model, through the setting of a card and mechanism, limits the lateral and longitudinal positions of the stepper motor base. By rotating the first forward and reverse threaded rod, the "I"-shaped slider can be centered and slid at any position, and by rotating the second forward and reverse threaded rod, the sliding plate can be stopped at any position. This achieves the advantage of being applicable to stepper motor bases of different lengths and widths, making it more flexible. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a stepper motor driven lifting support platform device.

[0026] like Figure 1-6 As shown, a stepper motor driven lifting support platform device includes a support platform 1. The support platform 1 is provided with a locking mechanism. The locking mechanism includes an "I"-shaped slider 2, a first forward and reverse threaded rod 3, a locking block 5, and a sliding plate 12. The "I"-shaped slider 2 is threadedly connected to two first forward and reverse threaded rods 3. The top of each of the two first forward and reverse threaded rods 3 is fixedly connected to a locking block 5. The locking block 5 is slidably connected to the sliding plate 12. Both ends of the sliding plate 12 are fixedly connected to a connecting frame 11. The connecting frame 11 is threadedly connected to a second forward and reverse threaded rod 10.

[0027] Please see Figure 2 It also includes a support platform 1, on which an "I"-shaped groove 100 is provided. Two "I"-shaped sliders 2 are slidably connected to the "I"-shaped groove 100. A through hole 101 is provided through the support platform 1. A forward and reverse threaded rod 3 is threadedly connected to the through hole 101. A crank handle 4 is fixedly connected to one end of the forward and reverse threaded rod 3. Both ends of the forward and reverse threaded rod 3 are provided with forward and reverse threads. The crank handle 4 drives the forward and reverse threaded rod 3 to rotate, causing the two "I"-shaped sliders 2 to slide towards the middle.

[0028] Please see Figure 1A stepper motor base 6 is placed on the top of the support platform 1. A sliding groove 50 is provided on the locking block 5. A slider 120 is fixedly connected to one side of the sliding plate 12. Two sliding grooves 50 are slidably connected in the slider 120. A stepper motor is installed on the stepper motor base 6. The stepper motor is not shown here. The sliding groove 50 limits the sliding plate 12 to slide horizontally. A lifting mechanism is installed at the bottom of the support platform 1 to achieve the effect of lifting the stepper motor on the support platform 1. The lifting mechanism is not shown here.

[0029] Please see Figure 5 A fixing ring 7 is fixedly connected to one side of the support platform 1. A stud 8 is threaded onto the fixing ring 7 and abuts against the outer circumference of the forward and reverse threaded rod 3. By screwing one end of the stud 8 downwards into the fixing ring 7 and abutting against the forward and reverse threaded rod 3, the continued rotation of the forward and reverse threaded rod 3 can be restricted.

[0030] Please see Figure 1 The top surface of the support platform 1 is fixedly connected to four brackets 9. Two brackets 9 form a group. Each group of brackets 9 is rotatably connected to a forward and reverse threaded rod 10. One end of the forward and reverse threaded rod 10 is fixedly connected to a crank handle 15. The forward and reverse threaded rod 10 is provided with forward and reverse threads. When the crank handle 15 is turned, the two connecting brackets 11 on the crank handle 15 drive the sliding plate 12 to slide towards the center.

[0031] Please see Figure 1 Each of the two brackets 9 is fixedly connected to a second fixing ring 13. The second fixing ring 13 is threadedly connected to a second stud 14 and abuts against the second reversible threaded rod 10. By screwing one end of the second stud 14 downward into the second fixing ring 13 and abutting against the second reversible threaded rod 10, the continued rotation of the second reversible threaded rod 10 can be restricted.

[0032] The implementation principle of a stepper motor driven lifting support platform device in this application embodiment is as follows:

[0033] When it is necessary to fix the stepper motor base 6 on the support platform 1, simply place the support platform 1 in the center first, and then limit and fix the lateral position of the support platform 1. Just turn the crank handle 4, which drives the forward and reverse threaded rod 3 to rotate. The forward and reverse threaded rod 3 is threadedly connected to the "I"-shaped slider 2, causing the "I"-shaped slider 2 to move towards the center. The locking block 5 moves synchronously as the "I"-shaped slider 2 slides in the center. Finally, the locking block 5 contacts the two lateral sides of the stepper motor base 6. After locking, stop turning the crank handle 4 and tighten the stud 8 downwards so that one end abuts against one end of the forward and reverse threaded rod 3 to achieve the effect of locking both ends of the stepper motor base 6.

[0034] Adjusting the longitudinal distance simply requires turning the crank handle 15. The crank handle 15 drives the forward and reverse threaded rod 10 to rotate. The rotation of the forward and reverse threaded rod 10 causes the connecting frame 11 to move in the center. The centering movement of the connecting frame 11 causes the sliding plate 12 to be limited on the locking block 5 and move in the center synchronously. Finally, the sliding plate 12 is locked onto the two longitudinal sides of the stepper motor base 6. The stud 14 is screwed down to make the stud 14 abut against the forward and reverse threaded rod 10 to prevent it from continuing to rotate, thereby achieving the advantage of positioning the longitudinal position of the stepper motor base 6.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
