Description

Technical Field

[0001] The utility model relates to the technical field of stepper motor installation, in particular to an adjustable stepper motor installation frame. Background Art

[0002] A stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. Under non-overload conditions, the speed and stop position of a stepper motor depend on the frequency and number of pulses of the pulse signal and are not affected by load changes. For each input pulse signal, the rotor will rotate an angle or move forward one step. The speed of a stepper motor is proportional to the pulse frequency, and the output angular displacement or linear displacement is proportional to the number of input pulses. When a stepper motor is in use, it needs to be fixed in place.

[0003] Existing stepper motors are directly welded to the machine during installation to prevent the stepper motor body from sliding during use, causing unnecessary safety hazards;

[0004] However, this installation method also completely fixes the position of the stepper motor body, which is not convenient for maintenance and replacement, and the output direction of the stepper motor body cannot be changed, which causes many inconveniences in daily use. Utility Model Content

[0005] The utility model aims to provide an adjustable stepper motor mounting bracket, which has the characteristics of being convenient for mounting and fixing stepper motors of different sizes and being able to change the direction of the output end of the stepper motor.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: comprising a stepper motor body, a base is provided at the bottom end of the stepper motor body, slide grooves are provided at the front and rear sides of the upper end of the base, positioning plates are provided at the front and rear sides of the upper end of the base, and the bottom ends of the two positioning plates are respectively slidably connected to the inside of the two slide grooves;

[0007] The front and rear ends of the upper end of the base are fixedly connected with fixed plates, one end of the two fixed plates is penetrated by two sliding holes, the inside of the four sliding holes is slidably connected with sliding rods, and the opposite ends of the four sliding rods are fixedly connected with limiting plates.

[0008] In order to facilitate the adjustment of the distance between the two positioning plates, an adjustable stepper motor mounting bracket is preferably used in the present invention. The middle parts of the bottom ends of the two positioning plates pass through the base and are fixedly connected with adjustment blocks. The left and right sides of the bottom end of the base are fixedly connected with adjustment plates. The interiors of the two adjustment blocks and the two adjustment plates are threaded with adjustment rods.

[0009] In order to facilitate clamping the stepper motor body, as a preferred embodiment of the adjustable stepper motor mounting bracket of the utility model, the outer walls of the four sliding rods are sleeved with springs.

[0010] In order to facilitate fixing the position of the horizontal plate, as a preferred adjustable stepper motor mounting bracket of the utility model, the front and rear sides of the bottom end of the base are fixedly connected with vertical plates, and the bottom ends of the two vertical plates are fixedly connected with horizontal plates.

[0011] In order to facilitate the rotation of the stepper motor body, as a preferred adjustable stepper motor mounting bracket of the utility model, the bottom end of the horizontal plate is fixedly connected with a movable rod, and the bottom end of the outer wall of the movable rod is movably connected with a rotating seat.

[0012] In order to prevent the slide bars from slipping off, as a preferred embodiment of the adjustable stepper motor mounting bracket of the utility model, the opposite ends of the four slide bars are fixedly connected to limit blocks.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model adjusts the distance between the two adjustment blocks and the two adjustment plates by rotating the two adjustment rods, thereby adjusting the distance between the two positioning plates, so that the two positioning plates slide relative to or away from each other, so as to fix the left and right sides of the stepping motor bodies of different sizes, and then the two limit plates move relative to or away from each other, driving the four springs to extend or contract, so as to clamp the stepping motor body at all times; then the rotating seat is fixed in an appropriate position, and since the outer wall of the movable rod is movably connected to the rotating seat, the direction of the output end of the stepping motor body can be adjusted according to the use requirements.
