Description

Technical Field

[0001] The utility model relates to the field of gears, in particular to a stepping motor assembled gear box. Background Art

[0002] A stepper motor is an electric motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. Based on the principle of electromagnetics, the stepper motor converts electrical energy into mechanical energy. Due to its good data control characteristics, the stepper motor is widely used in packaging machinery, printing machinery and other fields.

[0003] Gearboxes are a vital component widely used in mechanical transmissions. Their core functions include precise control, accurate speed, and torque control. The combination of a stepper motor and a gearbox can form a stepper reduction motor, further leveraging the advantages of both.

[0004] Existing gearboxes generally consist of two parts: a housing and a gear portion. The gear portion is connected to the inside of the housing via mounting plate bolts. During use and observation, it was found that multiple bolts need to be removed when repairing the gearbox, which is a rather cumbersome operation.

[0005] Therefore, in order to solve the above problems, a stepping motor assembled gear box is proposed. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the utility model describes a stepper motor assembled gear box, including a shell, a force shaft installed on the top of the shell; a mounting plate is provided inside the shell; a gear assembly is provided on the top of the mounting plate; a mounting hole is opened at the bottom of the mounting plate; the gear assembly, mounting hole, and force shaft are in a matching relationship; a second tooth plate is symmetrically fixed to the top of the mounting plate; a sliding rod is symmetrically set through the middle of the shell and slidably connected; the end of the sliding rod is fixedly connected to a spring; the spring and the shell are also in a fixed relationship; the other end of the sliding rod is fixedly connected to the first tooth plate; the first tooth plate and the second tooth plate are correspondingly set; the first tooth plate and the shell are slidably connected; the bite state of the first tooth plate and the second tooth plate can be controlled by pulling the sliding rod, so that the device can quickly install and disassemble the mounting plate, improve the convenience of the device for inspecting the gear assembly on the surface of the mounting plate, and simplify the operations required for disassembly of the mounting plate.

[0008] Preferably, the bottom of the sliding rod is fixed with a vertical rod; the bottom of the vertical rod is fixed with a rack; the rack and the shell are set through and are slidably connected; the inner wall of the shell is symmetrically connected to a gear; the adjacent racks and gears are in a meshing relationship; the bottom of the gear is fixed with an elastic plate; the elastic plate and the mounting plate are set correspondingly; through the meshing action of the rack and the gear, the gear can drive the elastic plate to support the mounting plate, thereby reducing the situation where the mounting plate slides out of the shell prematurely due to insufficient support when being disassembled, and improving the safety and stability of the mounting plate when being disassembled.

[0009] Preferably, a top plate is fixedly connected to the end of the elastic plate; the top plate is located at the bottom of the mounting plate; when the elastic plate supports the mounting plate, the top plate will also come into contact with the mounting plate, so that when the elastic force of the elastic plate weakens due to a long working time, the top plate can also support the mounting plate, ensuring that the mounting plate will not fall out of the shell and cause injury due to operational errors during disassembly.

[0010] Preferably, a protective pad is fixed to the middle of the top plate; the protective pad is located at the bottom of the mounting plate; when the top plate and the mounting plate are in contact, the protective pad will also come into contact with the mounting plate. Because the protective pad is a flexible structure, the protective pad will reduce the pressure caused by the mutual squeezing of the mounting plate and the top plate, thereby protecting both the top plate and the mounting plate.

[0011] Preferably, a plurality of balls are symmetrically connected to the middle part of the first tooth plate for rotation; the balls are located inside the shell; when the staff pulls the sliding rod to pull the first tooth plate, the first tooth plate will slide along the inner wall of the shell, and the balls will also come into contact with the inner wall of the shell. The balls will rotate under the action of friction, reducing the friction between the first tooth plate and the shell, and improving the smoothness of the first tooth plate when sliding along the shell.

[0012] Preferably, a plurality of positioning holes are provided in the middle of the slide rod; the positioning holes are arranged at equal intervals; because a plurality of positioning holes are provided on the surface of the slide rod, after the staff pulls the slide rod to disassemble the mounting plate, the positioning holes can be fixed by the latch, and the slide rod will be in a stable state under the fixing action of the latch. At this time, the staff can perform subsequent operations on the mounting plate, reducing the workload required for the staff to operate the slide rod and improving the convenience of the device when disassembling the mounting plate.

[0013] Preferably, a fluorescent ring is fixed to the middle of the sliding rod; the fluorescent ring is elastically set; when the staff pulls the sliding rod to disassemble the mounting plate, the fluorescent ring will move with the sliding rod. Because the fluorescent ring is elastically set, the fluorescent ring will slide out from the inside of the shell. When the fluorescent ring is outside the shell, the first tooth plate will be completely separated from the second tooth plate, and the mounting plate will also be in an active state. The staff can judge whether the mounting plate is in an active state by observing whether the fluorescent ring appears or not, thereby improving the convenience of the device in judging the status of the mounting plate.

[0014] Preferably, the end of the slide rod near the spring is fixed with a handle; the middle part of the handle is covered with a sponge; when the staff works, the palms of their hands will sweat due to long-term work. When the staff holds the handle with their palms, the sponge will absorb the sweat in the palms, thereby improving the stability of the staff when operating the handle and reducing the slipping when pulling the slide rod.

[0015] Preferably, the top plate surface is an arc-shaped transition; because the top plate surface is an arc-shaped transition, when the mounting plate and the top plate come into contact, they will slide along the surface of the top plate, reducing the resistance caused by friction between the mounting plate and the top plate.

[0016] Preferably, the surface of the protective pad is an arc-shaped structure; because the surface of the protective pad is an arc-shaped structure, the protective pad will deform under pressure when in contact with the mounting plate, and the protective pad will adapt to the surface contour of the mounting plate, thereby expanding the contact area between the protective pad and the mounting plate, and improving the protective effect of the protective pad on both the top plate and the mounting plate.

[0017] The utility model is beneficial in that:

The utility model describes a stepper motor assembled gear box, which can control the engagement state of the first tooth plate and the second tooth plate by pulling the slide rod, thereby realizing rapid installation and removal of the device to the mounting plate, improving the convenience of the device for inspecting the gear assembly on the surface of the mounting plate, and simplifying the operations required for disassembly of the mounting plate.

[0019] 2. The stepper motor assembled gearbox described in the present invention, through the meshing action of the rack and the gear, enables the gear to drive the elastic plate to support the mounting plate, thereby reducing the situation where the mounting plate slides out of the housing prematurely due to insufficient support when being disassembled, and improving the safety and stability when the mounting plate is disassembled.
