Description

Technical Field

[0001] This utility model relates to the field of linear motion module technology, specifically to a fully sealed high-precision linear motion module. Background Technology

[0002] Linear motion modules are mechanical transmission devices used to achieve high-precision linear reciprocating motion. They are widely used in automation equipment, CNC machine tools, 3D printing, robotics, battery and new energy industries, automotive manufacturing, electronics, biomedicine, jewelry, aviation, medical, hardware and building materials and other fields.

[0003] Existing linear motion modules convert the rotational motion of the motor into linear motion using a lead screw structure, which then drives a sliding structure to reciprocate linearly along a guide rail. Using a lead screw is prone to cumulative errors, resulting in low transmission efficiency, limited speed, and finite stroke and length, making it unsuitable for high-speed motion. Furthermore, the heat from the mover is directly conducted to the slide plate via thermal conduction, and then dissipated naturally through the outer surface of the slide plate, leading to poor heat dissipation for the mover. Given these shortcomings, it is necessary to design a fully sealed linear motion module for high-load grinding machines. Therefore, it is essential to design a fully sealed, high-precision linear motion module. Utility Model Content

[0011] Compared with the prior art, the technical solution provided by this utility model has at least the following technical effects or advantages: This invention features a reading head and a grating ruler. The reading head moves along the slide table on the grating ruler and reads the data, converting displacement into digital pulse signals for high-precision displacement measurement and feedback. It also includes a heat dissipation component. A powered cooling fan dissipates heat from the drive component, blowing it out of the sealed cover through ventilation holes, effectively improving heat dissipation for the drive component.

Because the magnetic stator and mover operate without contact, there is no friction or wear, and long-term operation does not affect the system's accuracy. Attached Figure Description

[0015] Please see Figure 1-4 As shown, this utility model provides a technical solution: a fully sealed high-precision linear motion module, including a base 1, a drive assembly 2, a slide 3, a sealing cover 4, a heat dissipation assembly 5, and a positioning assembly 6. The drive assembly 2 is installed on the base 1, the slide 3 is installed on the drive assembly 2, and the positioning assembly 6 is installed on the drive assembly 2. The drive assembly 2 is used to drive the slide 3 to perform reciprocating linear motion. Both ends of the slide 3 are equipped with sealing covers 4, and the heat dissipation assembly 5 is installed inside the sealing cover 4.

[0016] The drive assembly 2 in this embodiment includes a magnetic stator 208 and a mover 209. The magnetic stator 208 is mounted on the base 1, and the mover 209 is positioned above the magnetic stator 208. There is no contact between the magnetic stator 208 and the mover 209. A connecting plate 210 is mounted on the mover 209, and a slide 3 is mounted on the connecting plate 210. The magnetic stator 208 converts electricity into magnetic force. Under the action of the magnetic force, the mover 209 drives the slide 3 to perform reciprocating linear motion. A stop block 201 is mounted on the connecting plate 210, and limit blocks 202 are mounted at both ends of the base 1. The maximum stroke of the mover can be limited by the stop block 201 and the limit block 202 to prevent the mover from overshooting and being damaged due to excessive stroke. A slider 203 is mounted at the bottom of the slide 3. The slider 203 is slidably mounted on a slide rail 204, which is mounted on the base 1.

[0017] In this embodiment, a reading head mounting base is also installed at the bottom of the slide table 3. A reading head 205 is installed on the reading head mounting base. A grating ruler 206 is provided on one side of the reading head 205. The reading head 205 moves with the slide table 3 on the grating ruler 206 and reads data. It can convert displacement into digital pulse signals, thereby realizing high-precision displacement measurement and feedback. The grating ruler 205 is installed on the grating ruler fixing block, which is installed on the base 1. Protective plates 207 are installed on both sides of the base 1, and the two protective plates 207 are located below the slide table 3.

[0018] The heat dissipation component 5 in this embodiment includes a heat dissipation fan 501, which is mounted on a fan bracket 505. The two ends of the fan bracket 505 are mounted on the two side walls of the sealing cover 4. The sealing cover 4 is provided with a plurality of heat dissipation holes 502. A dust filter plate 503 is provided inside the sealing cover 4, and a dust filter layer 504 is provided on the outer side of each dust filter plate 503.

[0019] The positioning component 6 in this embodiment includes a positioning pin 601 and a cylinder 602 that drives the positioning pin 601 to move up and down. The positioning pin 601 is connected to the piston rod of the cylinder 602. The cylinder 602 is installed at the bottom of the slide table 3. A positioning plate 603 is provided below the positioning pin 601. The positioning plate 603 has multiple positioning holes and is installed on the base 1.

[0020] The working principle of this utility model is as follows: During use, the magnet stator 208 converts electricity into magnetic force. Under the action of magnetic force, the mover 209 drives the slide table 3 to perform reciprocating linear motion. The sealing cover 4 also moves with it, so that the sealing cover 4 covers the two protective plates 207 of the drive assembly 2, thereby playing a sealing and protective role. Since the magnet stator 208 and the mover 209 operate without contact with each other, there will be no friction or wear. Long-term operation will not affect the accuracy of the system. When the slide table 3 slides to the maximum stroke, the limit block 202 blocks the collision block 201, which can limit the maximum stroke of the mover 209 and prevent the mover 209 from running away and being damaged due to excessive stroke.

[0021] This utility model is equipped with a heat dissipation component 5. When the heat dissipation fan 501 is powered on, the drive component 2 is cooled. The heat dissipation fan 501 blows the heat out of the sealing cover 4 through the heat dissipation hole 502, thereby achieving the heat dissipation effect and effectively improving the heat dissipation effect of the drive component 2.

[0022] This utility model is equipped with a positioning component 6, which pushes the positioning pin 601 downward by the cylinder 602, so that the positioning pin 601 is inserted into the positioning hole of the positioning plate 603, thereby positioning the slide table 3 and improving the positioning accuracy of the slide table 3.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
