Description

Technical Field

[0001] The utility model belongs to the technical field of linear motors, and particularly relates to a linear motor. Background Art

[0002] A linear motor is a new type of linear drive technology developed recently. Due to the outstanding advantages of the linear motor such as zero transmission chain, non-contact, no backlash, high strength, and fast response, the linear motor is gradually replacing indirect servo mechanisms such as servo motors and ball screws and becoming the core functional component of high-speed and precision high-end equipment.

[0003] Chinese Utility Model Patent CN220234415U discloses a linear motor, including: a base, a mover body and a stator body, characterized in that: the mover body is located above the base, the stator body is fixedly installed above the base, a slide rail is fixedly installed on one side of the base close to the mover body, and a sliding sleeve is movably clamped outside the slide rail; by providing structures such as a first heat dissipation fin, a second heat dissipation fin, a circular groove and a heat dissipation fan, the device can be efficiently cooled, avoiding the problem of device failure caused by poor heat dissipation effect, so as to achieve the purpose of efficient heat dissipation.

[0004] In the above technical solution, anti-collision rods are fixedly arranged on both sides of the mover box in a symmetric distribution, and anti-collision plates are installed on both sides of the base. By cooperating the anti-collision rods with the anti-collision plates, the device can be prevented from colliding. However, during long-term use, the anti-collision rods hitting the anti-collision plates multiple times may cause the anti-collision rods to break, thus affecting the overall structural stability of the device and possibly posing a safety hazard to the normal operation of the equipment. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a linear motor for the above-mentioned existing technical problems, achieving buffering of the impacts at both ends of the linear motor, thereby improving the stability of the overall structure.

[0006] In view of this, the utility model provides a linear motor, including: a base, a stator body is fixedly installed above the base, a mover box is arranged above the stator body, a mover body is installed in the mover box, slide rails are fixedly installed at the upper ends of both sides of the base, a sliding sleeve slides on the slide rails, and one side of the sliding sleeve is connected to the mover box. The characteristic is that bottom plates are connected to both ends of the base, one side of the upper end of the bottom plate is connected to an anti-collision plate, a rubber plate is detachably connected to the side of the anti-collision plate close to the base, and further includes: a dust cleaning component, and the dust cleaning component is installed at the left and right ends of the sliding sleeve.

[0007] In this technical solution, when the mover body is energized, a magnetic field will be generated. The magnetic field will act on the magnets on the stator body, causing the mover body to perform a linear motion. The mover body drives the mover box and the sliding sleeve to move synchronously. The sliding sleeve slides on the surface of the slide rail. When the mover box approaches both ends of the base, the rubber plate provides an effective buffering effect for the mover box, reducing the direct impact of the impact force on the anti-collision plate and the mover box. And by the rubber plate detachably connected to the bottom plates at both ends of the base, the worn or aged rubber plate can be replaced regularly. The additional dust cleaning component is installed at the left and right ends of the sliding sleeve, which can automatically or manually remove the dust and impurities on the slide rail and the sliding sleeve, keep the sliding parts clean and smooth, reduce the increase in sliding resistance and the acceleration of wear caused by dust accumulation, and extend the service life of the equipment.

[0008] In the above technical solution, further, on both sides of the side of the anti-collision plate close to the base, there are limiting openings, and on the side of the rubber plate close to the anti-collision plate, there are limiting blocks adapted to the limiting openings, and the limiting blocks are slidably connected in the limiting openings.

[0009] In this technical solution, with the cooperation of the limiting blocks and the limiting openings, the rubber plate is slidably installed into the limiting openings. Moreover, the shape and size of the limiting blocks are closely matched with the limiting openings to prevent the rubber plate from shifting or falling off during use.

[0010] In the above technical solution, on the side of the anti-collision plate close to the base, there is also a guiding opening, and on the side of the rubber plate close to the anti-collision plate, there is a guiding block adapted to the guiding opening. Above the guiding opening at the upper end of the anti-collision plate, there is a limiting plate. Among them, one side of the limiting plate is hinged to the anti-collision plate by a bolt.

[0011] In this technical solution, the limiting plate is used to prevent the rubber plate from moving upward or coming out during use after installation. One side of the limiting plate is hinged to the anti-collision plate by a bolt. This connection method not only ensures the stability of the limiting plate but also facilitates adjustment or disassembly when needed.

[0012] In the above technical solution, the dust cleaning component includes: a U-shaped frame, and a brush is installed on the inner wall of the U-shaped frame, and the brush contacts the slide rail.

[0013] In this technical solution, on the inner wall of the U-shaped frame, there are densely arranged brushes. These brushes are usually made of soft and elastic materials such as nylon and polyester fiber to ensure that when contacting the slide rail, they can effectively remove dust and impurities without scratching the surface of the slide rail, and the brushes have no friction and do not affect the movement of the sliding sleeve on the slide rail.

[0014] In the above technical solution, further, on the side of the U-shaped frame away from the sliding sleeve, there is a sealing plate connected, and a buffer member is installed on the sealing plate.

[0015] In the above technical solution, further, the buffer member includes: a buffer frame, a buffer block is slidably connected in the buffer frame, a buffer spring is provided inside the buffer frame, one end of the buffer spring is connected to the inner wall of the buffer frame, and the other end is connected to the buffer block.

[0016] In this technical solution, when the buffer block is impacted, it will slide along the inside of the buffer frame and compress the buffer spring. The elastic deformation of the spring can absorb and disperse part of the impact force, thereby reducing the impact on the sealing plate, U-shaped frame and the entire dust cleaning assembly.

[0017] In the above technical solution, further, a load plate is provided on the side of the mover box away from the base, and mounting holes are formed in the load plate and distributed in a rectangular array.

[0018] In this technical solution, the load plate and the mounting holes facilitate the installation and connection of the device to be moved.

[0019] The beneficial effects of the present utility model are:

[0020] 1. The rubber plate provides an effective buffering effect for the mover box, reduces the direct impact of the impact force on the anti-collision plate and the mover box, and the rubber plate detachably connected to the bottom plates at both ends of the base can be regularly replaced when it is worn or aged.

[0021] 2. Dense brushes are installed on the inner wall of the U-shaped frame. These brushes are usually made of soft and elastic materials such as nylon and polyester fiber to ensure that when contacting the slide rail, they can effectively remove dust and impurities without scratching the surface of the slide rail, and the brushes have no friction and will not affect the movement of the sliding sleeve on the slide rail.
