Description

Technical Field

[0001] The utility model relates to the technical field of motor installation, in particular to a base of a stepping motor. Background Art

[0002] At present, a stepper motor is an electric motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. Every time a pulse signal is input, the rotor rotates an angle or moves forward one step. The output angular displacement or linear displacement is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. Therefore, a stepper motor is also called a pulse motor.

[0003] When installing a stepper motor, most of the time, the stepper motor is fixed by bolts installed on the base at the four corners of one side of the motor shaft.

[0004] Although the stepper motor can be installed on the base with four sets of bolts, as the motor is used for a long time, it will continue to vibrate, which will cause problems such as loose bolts, and it is very easy for the motor to fall out of the base. Therefore, a new technical solution needs to be designed to solve the problem, which can lock the motor firmly in the base. Utility Model Content

[0005] The purpose of the utility model is to provide a base of a stepping motor, which solves the problems raised in the background technology.

[0007] The motor support mechanism includes a support plate fixedly installed on the other side of the limiting slide, slide grooves opened at one end of both sides of the support plate, sliders slidably installed in two groups of the slide grooves, a concave frame fixedly installed on the outer walls of the two groups of sliders, and a support plate fixedly installed on the other side of the concave frame, and multiple groups of equidistantly distributed rubber pads are bonded to the top of the support plate.

[0008] As an optional solution of the technical solution of the present application, a motor is placed inside the base, the inner side of the abutment plate corresponds to the opposite end of the motor shaft, and the top of the support plate corresponds to the bottom side of the motor.

[0009] As an optional solution of the technical solution of the present application, first mounting holes are opened at four corners of one side of the base, and four groups of the first mounting holes correspond to the motor positioning holes, so that the motor can be installed in the first mounting holes.

[0010] As an optional solution of the technical solution of the present application, an axial hole is opened in the middle of one side of the base, and the axial hole corresponds to the motor shaft. Second mounting holes are opened at the four corners of the bottom of the base, and the base can be fixed on the mounting base.

[0011] As an optional solution of the technical solution of the present application, the two corresponding groups of sliders and one side of the concave frame are both threadedly connected with a first bolt, and the first bolt corresponds to the corresponding sliding grooves, which can fix the slider.

[0012] As an optional solution of the technical solution of the present application, second bolts are threadedly connected on both sides of the limiting slide groove, and two groups of the second bolts correspond to the two sides of the limiting slide plate respectively, so as to fix the limiting slide plate.

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

[0014] 1. The technical solution of the present application pushes the limiting slide plate in the limiting slide groove, pulls out the upper support plate of the motor support mechanism, adjusts the support plate, fits the inner side of the support plate with the side wall of the motor, cooperates with the slider in the sliding groove, and supports the bottom of the motor with the support plate on the outside of the concave frame, to ensure that when the left side wall of the motor is fixed by the base, the right side wall and the bottom side of the motor can be firmly locked by the support plate and the support plate, so that the motor is firmly limited inside the base, avoiding long-term vibration of the motor and falling off from the first mounting hole.

[0015] 2. In the technical solution of the present application, two groups of sliders and one side of the concave frame are threadedly connected with a first bolt, and both sides of the limiting slide groove are threadedly connected with a second bolt. When the right side wall and the bottom side of the motor can be firmly locked by the push plate and the support plate, the two groups of first bolts and the second bolts can be screwed together respectively, and the two groups of sliders and both sides of the limiting slide can be fixed respectively, thereby ensuring that the push plate and the support plate are firmly fixed to the right side wall and the bottom side of the motor.
