Description

Technical Field

[0001] This application relates to the field of guide rail technology, and more specifically, to a guide rail lubrication device. Background Technology

[0002] During the operation of mechanical equipment, the guide rail, as the core transmission structure for realizing the linear motion of components, directly determines the operating accuracy, transmission efficiency, and service life of the equipment through its lubrication condition. The guide rail and slider achieve rolling contact through balls or rollers. Over long-term operation, the metal contact surfaces are prone to wear due to friction. If lubrication is not timely or effective, it will lead to increased motion resistance, decreased positioning accuracy, and in severe cases, even guide rail scratches, ball jamming, and other malfunctions, causing equipment downtime for repair and increasing production and operating costs. Therefore, periodic lubrication of the guide rail is a crucial aspect of equipment maintenance.

[0003] Currently, the industry's conventional lubrication methods for guide rails mainly fall into two categories: one is to inject new lubricating oil through pre-set oil injection holes in the guide rail, where the lubricating oil, relying on its own fluidity and the reciprocating motion of the guide rail slider, is gradually distributed to the entire rail contact area by the rolling balls; the other is to use auxiliary tools such as brushes and cotton swabs to manually apply lubricating oil directly to the V-groove, ball rolling channels, and other metal contact surfaces of the guide rail. However, both of these lubrication methods have significant risks of uneven lubrication, are difficult to operate, and result in grease waste, making it difficult to meet the stringent lubrication requirements of high-precision equipment. Utility Model Content

[0005] The embodiments of this application are implemented as follows:

[0006] This application provides a guide rail lubrication device, including a mounting base and lubrication blocks disposed on both sides of the mounting base. The lubrication blocks are used to slide with the guide rail. The mounting base is provided with a communicating chamber for holding lubricating oil. The lubrication blocks are provided with an oil outlet pipe communicating with the communicating chamber and an oil outlet communicating with the oil outlet pipe. Lubricating oil is sprayed onto the grooves on both sides of the guide rail through the oil outlet.

[0007] Alternatively, as an implementable method, the lubricating block has an arc surface that matches the grooves on both sides of the guide rail, and the oil outlet is disposed on the arc surface.

[0008] Optionally, as an implementable method, the oil outlet includes multiple outlets, which are evenly distributed on the arc surface.

[0009] Alternatively, as an implementable method, the lubricating block is slidably connected to the mounting base, and the lubricating block slides toward or away from the mounting base to clamp or disengage from the guide rail.

[0010] Optionally, as an implementable method, the mounting base is provided with a groove, and the lubrication block is provided with a sliding plate that is slidably connected to the groove, and the lubrication block is slidably connected to the mounting base through the sliding plate.

[0011] Optionally, as an implementable approach, a resilient reset structure is also included, with its two ends connected to the slide plate and the mounting base, respectively.

[0012] Optionally, as an implementable method, the accommodating chamber is provided with a accommodating box that communicates with the oil outlet pipeline, and the accommodating box has outlets on both sides that are connected to the oil outlet pipeline.

[0016] The beneficial effects of the embodiments of this application include:

[0017] The guide rail lubrication device provided in this application includes a mounting base and lubrication blocks disposed on both sides of the mounting base. The lubrication blocks are used for sliding engagement with the guide rail. The mounting base has a reservoir for holding lubricating oil. The lubrication blocks are provided with an oil outlet pipe communicating with the reservoir and an oil outlet communicating with the oil outlet pipe. Lubricating oil is sprayed onto the grooves on both sides of the guide rail through the oil outlet. By setting lubrication blocks on both sides of the mounting base and accurately aligning the oil outlet with the grooves of the guide rail, the lubricating oil can directly act on the core contact area where the ball rolls. At the same time, the lubrication blocks are used for sliding engagement with the guide rail, which completely solves the problems of "local accumulation" when injecting oil into existing oil injection holes and "missed coating" or "over-coating" when manually applying oil. This effectively reduces local wear on the guide rail, ensures the operating accuracy and positioning accuracy of the equipment, and is especially suitable for the lubrication needs of high-precision equipment.

[0026] Please refer to Figure 1 and Figure 2 This embodiment provides a guide rail lubrication device 100, including a mounting base 110 and lubrication blocks 120 disposed on both sides of the mounting base 110. The lubrication blocks 120 are used to slide with the guide rail. The mounting base 110 is provided with a receiving chamber 111 for holding lubricating oil. The lubrication blocks 120 are provided with an oil outlet pipe 121 communicating with the receiving chamber 111 and an oil outlet 122 communicating with the oil outlet pipe 121. Lubricating oil is sprayed onto the grooves on both sides of the guide rail through the oil outlet 122.

[0027] Specifically, the guide rail lubrication device 100 includes a mounting base 110 and lubrication blocks 120 symmetrically arranged on both sides of the mounting base 110. The inner contour of the lubrication block 120 is adapted to the outer contour of the guide rail for sliding cooperation with the guide rail (i.e., the lubrication block 120 can move synchronously with the mounting base 110 along the length of the guide rail). The mounting base 110 is a hollow cavity structure, forming a storage chamber 111 for accommodating lubricating oil inside. An oil outlet pipe 121 is provided through the lubrication block 120. One end of the oil outlet pipe 121 is connected to the inside of the storage chamber 111, and the other end extends to the contact surface between the lubrication block 120 and the guide rail, forming an oil outlet 122 for supplying oil to the guide rail. Lubricating oil can be precisely sprayed onto the grooves on both sides of the guide rail (i.e., the ball rolling channel) through the oil outlet 122. An oil filling port is provided on the top of the mounting base 110, and a sealing plug is provided at the oil filling port for replenishing lubricating oil to the storage chamber 111 and preventing grease leakage. The lubricating block 120 is made of wear-resistant elastic material (such as nitrile rubber or polyurethane). The inner side of the block that fits with the guide rail is provided with an arc-shaped groove. The oil outlet 122 is located at the bottom of the arc-shaped groove to ensure that the oil outlet 122 is precisely aligned with the groove of the guide rail. A one-way valve is provided in the oil outlet pipeline 121.

[0028] In use, inject sufficient lubricating oil into the accommodating chamber 111, slide the guide rail lubrication device 100 onto the guide rail, so that the lubricating blocks 120 on both sides are in contact with the two side walls of the guide rail, and the oil outlet 122 is aligned with the groove of the guide rail; when the guide rail is slid relative to the sliding guide rail lubrication device 100, the mounting base 110 drives the lubricating blocks 120 to slide synchronously. Under the action of gravity and the slight vibration generated by the movement of the slider, the lubricating oil in the accommodating chamber 111 flows through the oil outlet pipe 121 to the oil outlet 122 and is evenly sprayed into the groove of the guide rail, so as to achieve real-time and uniform lubrication of the contact area between the guide rail and the ball bearing.

[0029] The guide rail lubrication device 100 provided in this application includes a mounting base 110 and lubrication blocks 120 disposed on both sides of the mounting base 110. The lubrication blocks 120 are used for sliding engagement with the guide rail. The mounting base 110 is provided with a receiving chamber 111 for holding lubricating oil. The lubrication blocks 120 are provided with an oil outlet pipe 121 communicating with the receiving chamber 111 and an oil outlet 122 communicating with the oil outlet pipe 121. Lubricating oil is sprayed onto the grooves on both sides of the guide rail through the oil outlet 122. By setting the lubrication blocks 120 on both sides of the mounting base 110 and accurately aligning the oil outlet 122 with the grooves of the guide rail, the lubricating oil can directly act on the core contact area of ​​the rolling ball. At the same time, the lubrication blocks 120 are used for sliding engagement with the guide rail, which completely solves the problems of "local accumulation" of oil in existing oil injection holes and "missed coating" and "over-coating" of manual application, effectively reducing local wear of the guide rail, ensuring the operating accuracy and positioning accuracy of the equipment, and is especially suitable for the lubrication needs of high-precision equipment.

[0030] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the lubricating block 120 has an arc surface 123 that fits into the grooves on both sides of the guide rail, and the oil outlet 122 is provided on the arc surface 123.

[0031] Specifically, the grooves on both sides of the guide rail for accommodating the balls are typically arc-shaped (matching the arc contour of the balls). To achieve precise fit between the lubricating block 120 and the guide rail, the side of the lubricating block 120 facing the guide rail is machined into an arc surface 123 that perfectly matches the arc-shaped groove—the radius of curvature and arc of the arc surface 123 are consistent with the guide rail groove, ensuring a gap-free fit between the lubricating block 120 and the guide rail groove. Simultaneously, the oil outlet 122 is directly opened on this arc surface 123, with the opening direction of the oil outlet 122 facing the inner wall of the guide rail groove (i.e., the contact area between the balls and the guide rail). When the lubrication device moves with the slider, the lubricating oil in the receiving chamber 111 is transported through the oil outlet pipe 121 to the oil outlet 122 on the arc surface 123, allowing the lubricating oil to be directly sprayed or penetrated into the inner wall of the guide rail groove, preventing lubricating oil loss in non-contact areas.

[0032] In one possible embodiment of this application, such as Figure 1 and Figure 2As shown, there are multiple oil outlets 122, which are evenly distributed on the arc surface 123.

[0033] Specifically, multiple oil outlets 122 are evenly distributed along the length of the arc surface 123 (e.g., one oil outlet 122 is set every 5-10 mm), and each oil outlet 122 is connected to the oil outlet pipeline 121 inside the lubrication block 120. The oil outlet pipeline 121 has a branching structure inside the lubrication block 120. The main pipeline connects to the receiving chamber 111, and the branch pipelines lead to each oil outlet 122 respectively, ensuring that the oil pressure and oil volume of each oil outlet 122 are consistent. For example, for the arc surface 123 of the lubrication block 120 with a length of 100 mm, 10 oil outlets 122 can be evenly arranged. The diameter of each oil outlet 122 is 0.5-1 mm, which avoids excessive grease flow due to excessively large diameter and also prevents blockage due to excessively small diameter.

[0034] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the lubricating block 120 is slidably connected to the mounting base 110, and the lubricating block 120 slides toward or away from the mounting base 110 to clamp or disengage from the guide rail.

[0035] Specifically, the lubricating block 120 is connected to the mounting base 110 via a sliding structure, with the sliding direction being horizontal (perpendicular to the length direction of the guide rail). When the lubricating block 120 slides towards the mounting base 110, the distance between the two lubricating blocks 120 decreases, clamping the guide rail. When the lubricating block 120 slides away from the mounting base 110, the distance between the two sides increases, allowing it to disengage from the guide rail for disassembly or adjustment of the device. For example, the mounting base 110 may have sliding rails on both sides, and the bottom of the lubricating block 120 may have a slider that matches the rails. By manually pushing the lubricating block 120 along the rails, clamping or disengaging actions can be achieved without the need for additional tools.

[0036] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the mounting base 110 is provided with a sliding groove 112, and the lubrication block 120 is provided with a sliding plate 124 that is slidably connected to the sliding groove 112. The lubrication block 120 is slidably connected to the mounting base 110 through the sliding plate 124.

[0037] Specifically, the mounting base 110 has strip-shaped grooves 112 on both side walls perpendicular to the length of the guide rail. The cross-section of the grooves 112 is "T"-shaped or "dovetail-shaped" to prevent the slide plate 124 from disengaging. The back of the lubrication block 120 is integrally formed or bolted with a slide plate 124 that matches the groove 112 (the slide plate 124 is made of wear-resistant metal, such as stainless steel). The slide plate 124 is embedded in the groove 112 and can slide freely along the groove 112. At the same time, limit blocks are provided at both ends of the groove 112 to prevent the slide plate 124 from sliding excessively and causing the lubrication block 120 to disengage from the mounting base 110, ensuring that the sliding stroke is controllable.

[0038] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, it also includes an elastic reset structure 130, with the slide plate 124 and the mounting base 110 connected to its two ends respectively.

[0039] Specifically, the elastic reset structure 130 uses a spring (such as a compression spring). One end of the spring is fixed to the inner side of the slide plate 124 (the side closest to the center of the mounting base 110) by a hook or bolt, and the other end is fixed to the side wall of the mounting base 110. In its natural state, the spring is in a compressed state, and the elastic force pushes the two slide plates 124 to move away from the mounting base 110, so that the two lubricating blocks 120 clamp the guide rail. When it is necessary to disassemble the device, the lubricating blocks 120 are manually pushed towards the center of the mounting base 110 to compress the spring and widen the distance between the two lubricating blocks 120, so that they can be disengaged from the guide rail. After releasing the hand, the elastic force of the spring can automatically push the lubricating blocks 120 to reset and re-clamp the guide rail.

[0040] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the container 111 is provided with a container box 113 that is connected to the oil outlet pipe 121, and the container box 113 has outlets on both sides that are connected to the oil outlet pipe 121.

[0041] Furthermore, the oil outlet line 121 is a corrugated pipe, and the extension direction of the corrugated pipe is consistent with the sliding direction of the mounting base 110. Understandably, the side wall of the receiving box 113 is also corrugated.

[0042] Specifically, the bellows extends in the same direction as the sliding direction, allowing it to stretch or compress as the lubricating block 120 slides without bending or breaking. The bellows' extensibility meets the length requirements of the oil outlet pipe 121 during the sliding process of the lubricating block 120, avoiding breakage or sealing failure of traditional rigid pipes due to the sliding of the lubricating block 120, and ensuring that the oil circuit remains unobstructed.

[0043] In one possible embodiment of this application, such as Figure 1 and Figure 2As shown, the mounting base 110 is also equipped with an oil conveying device that communicates with the container 111. The oil conveying device is equipped with a regulating valve, which is used to regulate the oil conveying volume of the oil conveying device.

[0044] The oil delivery device includes an oil storage tank, an oil delivery pipe, and a miniature oil pump (such as a manual or electric pump): the oil storage tank is fixed to the top of the mounting base 110 and connected to the receiving chamber 111 via the oil delivery pipe; the miniature oil pump is installed on the oil delivery pipe to deliver the lubricating oil from the oil storage tank to the receiving chamber 111; the regulating valve is a knob-type throttle valve installed on the oil delivery pipe, and the flow area of ​​the oil delivery pipe can be changed by rotating the knob—clockwise rotation of the knob decreases the flow area and reduces the oil delivery volume; counterclockwise rotation increases the flow area and increases the oil delivery volume. Simultaneously, the oil delivery device is equipped with an oil level observation window, allowing real-time monitoring of the oil delivery volume for precise adjustment.

[0045] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, a pull rod 140 is hinged to the mounting base 110, and the mounting base 110 slides on the guide rail through the pull rod 140.

[0046] Specifically, when it is necessary to manually move the mounting base 110, rotate the lever 140 around the hinge to a horizontal position, and then hold the other end of the lever 140 to push or pull the mounting base 110 to slide along the guide rail.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
