Description

Technical Field

[0001] This utility model relates to the field of linear module technology, and more specifically, to a wear-resistant linear module. Background Technology

[0002] Linear modules are widely used in automated equipment, and their core function is to achieve precise linear motion. Traditional linear modules mainly rely on mechanical rolling or sliding guide structures (such as ball bearing guides and slider guides), which face serious wear problems during long-term, high-frequency operation.

[0003] Mechanical contact wear: Continuous friction between the balls and the guide rail leads to material fatigue, increased clearance, and reduced positioning accuracy and service life;

[0004] Highly dependent on lubrication: requires regular manual application of lubricant, resulting in high maintenance costs and localized wear due to uneven lubrication;

[0005] Vibration and noise: Mechanical contact can easily cause vibration, affecting the stability of high-precision equipment.

[0006] To reduce wear, existing technologies propose two directions for improvement:

[0007] Magnetic levitation technology: This technology uses electromagnetic force to levitate the sliding seat, completely eliminating mechanical contact. However, this method has significant drawbacks:

[0008] The control circuit is complex and expensive;

[0009] There is a risk of falling during power outages or electromagnetic interference.

[0010] The load capacity is limited by the magnetic field strength.

[0011] Hybrid structure: Combining magnetic guidance and rolling support, but the existing design fails to effectively integrate the lubrication system, and the ball bearings still suffer from wear accumulation.

[0012] Therefore, there is an urgent need for a new type of linear module that combines low wear, high reliability and low maintenance cost, while retaining the advantages of magnetic levitation and achieving wear control throughout the entire life cycle through innovative mechanical structure and automatic lubrication mechanism. Utility Model Content

[0013] The problem this invention addresses is: how to reduce the wear of linear modules.

[0014] To solve the above problems, this utility model provides a wear-resistant linear module, comprising:

[0015] Linear module main body;

[0016] Permanent magnets arranged along the length of the main body of the linear module;

[0017] A slide block is provided with a magnetic component that magnetically engages with the permanent magnet, allowing the slide block to move along the length of the linear module body;

[0018] Guide rail coils are located on both sides of the main body of the linear module;

[0019] A levitation coil is installed at the bottom of the slide block, and the levitation coil is magnetically engaged with the guide rail coil to put the slide block in a magnetic levitation state;

[0020] L-shaped guide rail fixed to the main body of the linear module;

[0021] An L-shaped bracket fixed to the slide has a linear ball array on its inner side, and the linear ball array makes rolling contact with the L-shaped guide rail;

[0022] An automatic lubrication device mounted on an L-shaped bracket delivers lubricant to the linear ball array via a piping system.

[0023] Optionally, the permanent magnets are embedded inside the main body of the linear module and are arranged at equal intervals along the length direction.

[0024] Optionally, the guide rail coils are symmetrically distributed on the left and right sides of the linear module body and aligned with the suspension coils in the vertical direction.

[0025] Optionally, the angle between the L-shaped bracket and the L-shaped guide rail is 90°, forming a right-angle guide structure that fits into each other.

[0026] Optionally, the linear ball array includes multiple sets of balls arranged continuously along the sliding direction, with each set of balls contacting the top, bottom, and sides of the L-shaped guide rail.

[0027] Optionally, the magnetic levitation gap between the levitation coil and the guide rail coil is 0.1 to 0.5 mm.

[0028] Optionally, the automatic lubrication device includes an oil reservoir, a pressure pump, and a micro-orifice nozzle, and the piping system delivers lubricant in a directional manner to the contact interface of the linear ball array.

[0029] Optionally, a position sensor is provided at the bottom of the slide to monitor the magnetic levitation gap in real time and provide feedback to control the current of the levitation coil.

[0030] Compared with the prior art, the wear-resistant linear module of this utility model has the following beneficial effects:

[0031] This invention utilizes the mutual repulsion of electromagnetic forces between the guide rail coil and the suspension coil to levitate the slide block, eliminating mechanical contact and thus eliminating sliding friction through magnetic levitation. Magnetic drive: The magnetic components of the slide block interact with the permanent magnet to generate axial driving force; Mechanical friction reduction: In the suspended state, the weight of the slide block is borne by magnetic force, and the residual force is offset by the rolling friction of the ball array; Automatic lubrication: Lubricant is continuously injected through pipelines to form an oil film at the ball-guide rail interface. The automatic lubrication system eliminates the need for manual intervention. Attached Figure Description

[0039] like Figures 1 to 2 As shown, this utility model embodiment provides a wear-resistant linear module, comprising:

[0040] Linear module main body 100;

[0041] Permanent magnets 130 are arranged along the length of the linear module body 100;

[0042] The slide 120 is provided with a magnetic component 160 that magnetically engages with the permanent magnet 130, so that the slide 120 can move along the length of the linear module body.

[0043] Guide rail coils 110 are disposed on both sides of the linear module body 100;

[0044] The levitation coil 150 is located at the bottom of the slide 120. The levitation coil 150 and the guide rail coil 110 are magnetically engaged, so that the slide 120 is in a magnetic levitation state.

[0045] L-shaped guide rail 200 fixed to linear module body 100;

[0046] The L-shaped bracket 210 fixed to the slide 120 has a linear ball array 240 on its inner side, and the linear ball array 240 makes rolling contact with the L-shaped guide rail 200.

[0047] An automatic lubrication device 220, mounted on an L-shaped bracket 210, delivers lubricant to the linear ball array 240 via a piping system 230.

[0048] The permanent magnet 130 is embedded inside the linear module body 100 and arranged along the length direction;

[0049] A suspension coil 150 is installed at the bottom of the slide block 120, and guide rail coils 110 are installed on the linear module bodies 100 on both sides.

[0050] The L-shaped guide rail 200 is fixed on the module body 100, and the L-shaped bracket 210 is fixed inside the slide block 120;

[0051] The linear ball array 240 is embedded in the groove of the bracket 210 and forms a rolling contact with the guide rail 200;

[0052] The automatic lubrication device 220 is connected to the ball contact point via a pipe 230.

[0053] This solution has the following technical advantages:

[0054] Magnetic levitation: The guide rail coil 110 and the suspension coil 150 repel each other through electromagnetic force, causing the slide 120 to levitate and break away from mechanical contact. Magnetic levitation eliminates sliding friction.

[0055] Magnetic drive: The magnetic component 160 of the slide 120 interacts with the permanent magnet 130 to generate axial driving force;

[0056] Mechanical friction reduction: In the suspended state, the gravity of the sliding seat is supported by magnetic force, and the residual force is offset by the rolling friction of the ball array 240;

[0057] Automatic lubrication: Lubricant is continuously injected into the ball-rail interface via pipeline 230 to form an oil film. The automatic lubrication system eliminates the need for manual intervention.

[0058] Permanent magnets 130 are embedded inside the linear module body 100 and arranged at equal intervals along the length direction. The permanent magnets 130 are embedded in the T-slots of the module body 100 at fixed intervals, such as 20mm. The equidistant arrangement forms a uniform magnetic field gradient, avoiding thrust fluctuations when driving the slide.

[0059] The guide coils 110 are symmetrically distributed on the left and right sides of the linear module body 100, and are vertically aligned with the suspension coil 150. The guide coils 110 are symmetrically mounted on both sides of the module body 100, and the suspension coil 150 is center-aligned. The symmetrical magnetic field cancels out the lateral load force, and the magnetic force is uniformly distributed in the vertical direction.

[0060] The L-shaped bracket 210 and the L-shaped guide rail 200 form a 90° angle, creating a right-angle guide structure that fits together. The vertical angle between the L-shaped bracket 210 and the guide rail 200 is strictly 90°, which is ensured through precision machining.

[0061] The linear ball array 240 includes multiple sets of balls arranged continuously along the sliding direction, with each set of balls contacting the top, bottom, and sides of the L-shaped guide rail 200. The ball sets are closely arranged along the sliding direction with a spacing ≤ the ball diameter, and each set of balls simultaneously contacts the upper surface and sides of the guide rail 200.

[0062] In this embodiment, the magnetic levitation gap between the levitation coil 150 and the guide rail coil 110 is 0.1 to 0.5 mm.

[0063] The automatic lubrication device 220 includes an oil reservoir, a pressure pump, and a micro-orifice nozzle, and the piping system 230 delivers lubricant in a directional manner to the contact interface of the linear ball array 240.

[0064] The oil reservoir is filled with semi-solid grease; the pressure pump starts according to the stroke cycle; the micro-orifice nozzle with a diameter of 0.1mm is aligned with the ball-rail contact line for spraying. This achieves quantitative lubrication.

[0065] A position sensor is installed at the bottom of the slide 120 to monitor the magnetic levitation gap in real time and provide feedback to control the current of the levitation coil 150. An eddy current sensor monitors the levitation gap; the PLC adjusts the current of the levitation coil 150 in real time.

[0066] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
