Description

Technical Field

[0001] The utility model relates to the technical field of linear motors, in particular to a modular linear motor. Background Art

[0002] A linear motor is a transmission device that converts electrical energy directly into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotating motor cut radially and unfolded into a plane. Linear motors are also called linear motors, linear motors, linear motors, and push rod motors. The most commonly used linear motor types are flat plate type, U-shaped slot type, and tube type. The typical composition of the coil is three-phase, and brushless commutation is achieved by Hall elements.

[0003] For example, a modular linear motor with a slide rail, which is published as CN210608886U, achieves the effect of placing a guide rail by setting a bottom plate and a first groove, and achieves the effect of driving the slider to move by the guide rail, and achieves the effect of driving the fixed plate to move by the slider, and achieves the effect of placing a linear motor by the fixed plate, and achieves the effect of driving the first clamping plate to move by the electric telescopic rod, and achieves the effect of fixing linear motors of different sizes by the first clamping plate and the second clamping plate. The modular linear motor with a slide rail is convenient for fixing motors of different sizes, and is convenient for people to use. However, the device still has certain defects;

[0004] Lubricating oil needs to be applied to the guide rails regularly. If the guide rails are not lubricated in time, the linear motor will continue to rub against the slider mechanism as it moves back and forth through the guide rails, which will accelerate the wear between the guide rails and the slider mechanism, thereby reducing their service life and increasing the labor intensity of the staff.

[0005] So we proposed a modular linear motor to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a modular linear motor to solve the problem raised by the above-mentioned background technology that the guide rails of the existing linear motors on the market need to be manually lubricated regularly. If the guide rails are not lubricated in time, the linear motor will continuously rub against the slider mechanism during the process of moving back and forth through the guide rails, which will accelerate the wear between the guide rails and the slider mechanism, thereby reducing the service life of the guide rails and the slider mechanism and increasing the labor intensity of the staff.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a modular linear motor, comprising a linear motor base, a fixed slide rail, a stator plate, a mounting seat, and a sponge block, the linear motor base is symmetrically provided with mounting holes on the front and rear sides, and a fixed slide rail is installed above the linear motor base, and a stator plate is installed on the upper surface of the linear motor base, and magnetic pole blocks are equidistantly installed on the stator plate, a slider mechanism is provided on the fixed slide rail, and a mounting seat is installed on the slider mechanism, and a mover mechanism is installed on the left side of the mounting seat, an oil filter hole is provided on the right bottom of the fixed slide rail, a lubricating oil tank is installed on the linear motor base and the left side of the fixed slide rail, a sponge block is installed on the left side of the fixed slide rail, and an oil pipe is connected to the left side of the sponge block.

[0008] Preferably, a plurality of mounting holes are provided, and the mounting holes are equidistantly distributed on the front and rear sides of the linear motor base.

[0009] With the above structural design, the linear motor is placed at the position where it is needed, and the linear motor is fixed through the mounting holes on the linear motor base. Fixing bolts can be sleeved on the mounting holes to facilitate installation and removal of the linear motor.

[0010] Preferably, a sliding structure is formed between the fixed slide rail and the slider mechanism, and the slider mechanism is fixedly connected to the bottom surface of the mounting seat.

[0011] With the above structural design, the slider mechanism can move linearly along the fixed slide rail when subjected to force, and the slider mechanism is more stable when moving left and right without deviation, and then the slider mechanism drives the upper mounting seat to move linearly.

[0012] Preferably, a coil and an iron core are provided inside the movable mechanism, and a power line is installed outside the movable mechanism, and the power line is electrically connected to the coil inside the movable mechanism.

[0013] With the above structural design, when the linear motor needs to be started, the power cord is connected to the power supply, so that the coil in the mover mechanism is energized, and then a magnetic field is generated. At the same time, the magnetic pole blocks on the stator plate generate a constant magnetic field. According to the principle that like poles repel and opposite poles attract, the mover mechanism can move left and right, thereby driving the slider mechanism and the mounting seat to move left and right.

[0014] Preferably, the oil filter hole is connected to the oil return pipe, and the oil return pipe is located outside the linear motor base and the fixed slide rail, and the left end of the oil return pipe is connected to the lubricating oil tank.

[0015] By adopting the above structural design, the excess lubricating oil in the fixed slide rail can flow out through the oil filter hole and be transported to the lubricating oil tank through the oil return pipe, thereby facilitating the collection of the lubricating oil, avoiding the waste of lubricating oil and saving lubrication costs.

[0017] With the above structural design, when the slider mechanism moves to be close to the sponge block, the slider mechanism pushes the movable rod to move to the left, and then makes the sealing plate at the left end of the movable rod move away from the oil pipe. At this time, the telescopic spring is in a stretched state, and the lubricating oil in the lubricating oil tank can enter the oil pipe through the gap between the sealing plate and the oil pipe, and enter the sponge block through the oil pipe. The sponge block applies the lubricating oil to the surface of the slider mechanism, thereby realizing automatic application of lubricating oil to the slider mechanism. When the slider mechanism is away from the sponge block, the sealing plate is reset under the action of the rebound force of the telescopic spring, and the sealing plate is in close contact with the oil pipe, thereby completing the sealing of the oil pipe.
