Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, and in particular to an automatic lubrication guide rail module. Background Technology

[0002] A guide rail is a fundamental mechanical component that guides mechanical parts to achieve directional linear or reciprocating motion. The guide rail body is mostly made of metal with a track on its surface. Sliding parts fit into the track and can move along a preset path. Its structural design must meet the requirements of high precision, high rigidity, and low friction, ensuring the accuracy of component displacement by constraining the direction of motion. Guide rails are widely used in machine tools, automation equipment, and robotics, and are core components for achieving precise transmission and positioning in mechanical systems. Their performance directly affects the operating accuracy and stability of the entire equipment.

[0003] During operation, friction occurs between the sliding components and the guide rail body at their contact surfaces. Prolonged friction not only increases energy consumption but also leads to wear on the contact surfaces, affecting motion accuracy and service life. Lubrication forms an oil film between the contact surfaces, converting solid friction into liquid friction and significantly reducing the coefficient of friction. Simultaneously, grease isolates the contact surfaces from air and moisture, preventing corrosion and reducing the abrasive effect of impurities on the moving parts. For guide rails operating at high speeds or under heavy loads, lubrication also removes heat generated by friction, preventing component deformation or lubrication failure due to excessive temperature. Therefore, lubrication is essential for maintaining the efficient, stable, and long-term operation of guide rails, directly impacting equipment performance and maintenance costs.

[0004] Existing guide rails are lubricated manually by periodically applying grease. The grease forms an oil film on the contact surface, preventing severe wear caused by dry friction and ensuring the basic operational requirements of the guide rails to a certain extent. However, the existing device requires operators to manually disassemble the protective components, evenly apply grease to the guide rail surface and inside the grooves, and then reassemble. This method relies on the rhythm of manual operation, making it difficult to adjust the amount of lubrication according to the actual operating frequency and load changes of the guide rails, which can easily lead to insufficient or excessive lubrication. Furthermore, manual lubrication requires interrupting equipment operation, which, especially in automated production lines, reduces production efficiency due to frequent shutdowns for lubrication. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic lubrication guide rail module, which aims to improve the existing technology where manual application of grease is prone to insufficient or excessive lubrication, and manual lubrication requires interruption of equipment operation, which can reduce production efficiency, especially in automated production lines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic lubrication guide rail module, comprising a guide rail body, a slider, and two sliding pieces. The guide rail body has sliding grooves on both sides. The inner flanges of the two sliding pieces are respectively attached to the inner sides of the two sliding grooves. The two sliding pieces are slidably connected on the top of the guide rail body through the two sliding grooves. Lubrication mechanisms are provided on both the left and right sides inside the guide rail body. The lubrication mechanisms are used to automatically inject a small amount of grease into the exterior of the guide rail body. A replacement mechanism is provided between the slider and the two sliding pieces. The replacement mechanism is used to replace sliders of different specifications.

[0007] The lubrication mechanism includes two pump bodies, which are fixedly connected to the left and right sides of the guide rail body. Each of the two pump bodies has a pusher fixedly installed on its exterior. The pushers are installed on the inner sides of two slide grooves. Each of the two pump bodies has a piston installed inside its interior. The input ends of the two pistons are connected to elastic suction tubes. The output ends of the two pushers are connected to double-headed nozzles.

[0008] As a further description of the above technical solution:

[0009] The replacement mechanism includes two rubber pads, which are respectively attached to the front and rear sides of two sliders. A positioning rod is fixedly connected to the middle of the front and rear sides of each slider. Positioning holes are opened in the middle of the outer sides of the two sliders and the rubber pads. Fastening screws pass through the left and right sides of the outer sides of the two sliders. The ends of the multiple fastening screws are respectively threaded to the left and right ends of the front and rear sides of the sliders.

[0010] As a further description of the above technical solution:

[0011] A storage tank is provided at the bottom of the guide rail body, and a connecting bolt passes through the top of the guide rail body. The end of the connecting bolt is threaded to the top of the storage tank.

[0012] As a further description of the above technical solution:

[0013] The bottom of the storage tank is threaded with a pressure screw, and the top of the pressure screw is fixedly connected with a pressure plate, which is slidably connected inside the storage tank.

[0014] As a further description of the above technical solution:

[0015] A pressure wristband is fixedly connected to the bottom end of the pressure screw. The outer surface of the pressure wristband adopts a ring design and has an anti-slip design.

[0016] As a further description of the above technical solution:

[0017] Multiple sealing rings are fixedly connected at equal intervals on the outer side of the pressure plate, and the outer surfaces of the multiple sealing rings are in contact with the inner wall of the storage tank.

[0018] As a further description of the above technical solution:

[0019] A grease inlet is provided on the upper rear side of the storage tank, and the output end of the grease inlet is connected to the inside of the storage tank.

[0020] As a further description of the above technical solution:

[0021] Both of the inner flanges of the two sliders are rounded, and the outer part of the push head is hemispherical.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the piston in the pump body is squeezed to compress the grease by pressing the pusher head, and a lubricating layer is formed through the double-headed nozzle. When the piston returns to its original position, the elastic suction tube replenishes the grease, realizing automatic lubrication of the contact area between the slide groove and the slide plate. The injection volume is adjusted with the sliding frequency, avoiding insufficient or excessive manual application, and solving the problem of production interruption caused by machine stoppage.

[0024] 2. In this utility model, a rubber pad is used for buffering, a positioning rod is inserted into the positioning hole for positioning, and a screw is tightened to fix the slider and the slide plate. When replacing, the screw is loosened, the positioning rod is pulled out, and the slider is replaced and then reset and fixed. This achieves a stable connection between the slider and the slide plate, ensuring accurate positioning, uniform force distribution, and absorption of vibration to prevent loosening. Different specifications of sliders can be quickly replaced to adapt to different load requirements, simplifying maintenance and ensuring sliding accuracy and module versatility.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides an automatic lubrication guide rail module, including a guide rail body 1, a slider 2, and two sliders 3. The guide rail body 1 has sliding grooves 4 on both sides. The inner flanges of the two sliders 3 are respectively attached to the inner sides of the two sliding grooves 4. The two sliders 3 are slidably connected on the top of the guide rail body 1 through the two sliding grooves 4. Lubrication mechanisms 5 are provided on both the left and right sides inside the guide rail body 1. The lubrication mechanisms 5 are used to automatically inject a small amount of grease into the outside of the guide rail body 1. A replacement mechanism 6 is provided between the slider 2 and the two sliders 3. The replacement mechanism 6 is used to replace sliders 2 of different specifications.

[0034] The lubrication mechanism 5 includes two pump bodies 51, which are fixedly connected to the left and right sides of the inside of the guide rail body 1 respectively. Each of the two pump bodies 51 has a push head 52 fixedly installed on its exterior. The two push heads 52 are installed on the inside of the two slide grooves 4 respectively. Each of the two pump bodies 51 has a piston 53 installed inside its exterior. The input end of each of the two pistons 53 is connected to an elastic suction tube 54. The output end of each of the two push heads 52 is connected to a double-headed nozzle 55. The inner flanges of the two slide plates 3 are rounded, and the exterior of the push head 52 is hemispherical.

[0035] Specifically, the grooves 4 on both sides of the guide rail body 1 provide a sliding path for the slide pieces 3. The inner flanges of the two slide pieces 3 fit against the inner side of the grooves 4, so that the slide pieces 3 can slide stably along the top of the guide rail body 1. The slider 2 is connected to the two slide pieces 3 through the replacement mechanism 6 and moves synchronously with the slide pieces 3.

[0036] In the lubrication mechanism 5 on the left and right sides inside the guide rail body 1, the pump body 51 is fixedly installed, and the external pusher 52 is located inside the slide groove 4. The hemispherical design of the pusher 52 is adapted to the smooth design of the inner flange of the slide plate 3. When the slide plate 3 slides along the slide groove 4 and passes the pusher 52, the flange of the slide plate 3 contacts and presses the pusher 52, causing the pusher 52 to retract into the pump body 51. The pressing of the pusher 52 drives the piston 53 inside the pump body 51 to move, squeezing the grease inside the pump body 51, so that the grease is sprayed out through the double-headed nozzle 55 at the output end of the pusher 52. The double-headed nozzle 55 guides the grease to the contact surface between the inner side of the slide groove 4 and the slide plate 3 to form a lubrication layer.

[0037] When the slide plate 3 slides past the push head 52, the push head 52 loses external pressure, and the piston 53 returns to its original position under its own elasticity. New grease is drawn in from the outside through the elastic suction tube 54 and replenished into the pump body 51 to prepare for the next press. The continuous sliding of the slide plate 3 causes the push head 52 to be pressed repeatedly, realizing the automatic small-volume injection of grease and ensuring that the contact area between the slide groove 4 and the slide plate 3 is always lubricated.

[0038] The design of the lubrication mechanism 5 links the amount of grease injected to the sliding frequency of the slide 3. The more frequently the slide 3 moves, the more times the grease is injected, adapting to the lubrication needs under different usage intensities. The hemispherical design of the push head 52 and the smooth design of the flange of the slide 3 work together to reduce frictional resistance and mechanical wear during the pressing process, extending the service life of the parts. The dual-head nozzle 55 ensures that the grease can evenly cover the contact surface, improving the lubrication effect.

[0039] The replacement mechanism 6 connects the slider 2 and two slide plates 3. Through its structural characteristics, the slider 2 can be quickly separated or combined with the slide plates 3 to meet the needs of replacing sliders 2 of different specifications and adapt to working scenarios with different load or motion accuracy requirements.

[0040] The synchronous movement of slider 2 and slide plate 3 drives the load movement. The lubrication mechanism 5 provides lubrication in real time, reducing friction loss during the sliding process and ensuring smooth movement. The replacement mechanism 6 improves the versatility and ease of maintenance of the module, enabling the entire guide rail module to maintain efficient and stable operation under different working conditions.

[0041] Reference Figure 1 and Figure 4 The replacement mechanism 6 includes two rubber pads 61, which are respectively attached to the front and rear sides of the two sliders 2. Positioning rods 62 are fixedly connected to the middle of the front and rear sides of the sliders 2. Positioning holes 63 are opened in the middle of the outer sides of the two sliders 3 and the rubber pads 61. Fastening screws 64 pass through the left and right sides of the outer side of the two sliders 3. The ends of the multiple fastening screws 64 are respectively threaded to the left and right ends of the front and rear sides of the sliders 2.

[0042] Specifically, the two rubber pads 61 of the replacement mechanism 6 are respectively attached to the front and rear sides of the slider 2. When the slider 2 is connected to the two slide plates 3, the rubber pads 61 are located between the slider 2 and the slide plates 3, forming a buffer layer. The positioning rod 62 in the middle of the front and rear sides of the slider 2 corresponds to the positioning hole 63 in the middle of the outer side of the slide plate 3 and the rubber pad 61. When connected, the positioning rod 62 is inserted into the positioning hole 63 to position the slider 2 and the slide plate 3 from the center position to ensure that the relative positions of the two are accurate.

[0043] The fastening screws 64 on the left and right sides of the two sliders 3 pass through the sliders 3 and the rubber pad 61, and the ends are threaded to the front and rear left and right ends of the slider 2. The screws tighten the sliders 3, the rubber pad 61 and the slider 2 into one unit. The symmetrical distribution of the fastening screws 64 on the left and right sides makes the connection between the slider 2 and the sliders 3 evenly stressed, avoiding loosening of the connection or deformation of the parts caused by unilateral stress.

[0044] The rubber pad 61 undergoes slight deformation under the pressure of the fastening screw 64, filling the gap between the slider 2 and the slide 3 and enhancing the tightness of the connection; at the same time, the elastic properties of the rubber material can absorb the vibration generated during the movement of the slider 2, reduce the loosening of the fastening screw 64 due to vibration, and maintain the stability of the connection.

[0045] When it is necessary to replace the slider 2 with a different specification, loosen and remove the fastening screw 64 to separate the slider 3 from the slider 2; pull out the positioning rod 62 from the positioning hole 63, and remove the rubber pad 61 along with the slider 2; when replacing the new slider 2, align the positioning rod 62 on the front and rear sides of the new slider 2 with the positioning holes 63 of the slider 3 and the new rubber pad 61 and insert it, then pass the fastening screw 64 through the slider 3 and the rubber pad 61 and thread it to the new slider 2 to complete the replacement;

[0046] The cooperation between the positioning rod 62 and the positioning hole 63 ensures that the relative position of the slider 2 and the slide plate 3 remains consistent after each replacement of the slider 2, avoiding the impact of connection deviation on the sliding accuracy of the slider 2 along the guide rail body 1; the replaceability of the rubber pad 61 allows it to adapt to the mounting surface size of sliders 2 of different specifications, enhancing the versatility of the replacement mechanism 6.

[0047] The threaded connection of the fastening screw 64 allows the replacement of slider 2 to be completed without special tools, simplifying the maintenance process; the replacement mechanism 6, through multiple functions of positioning, fastening and buffering, not only ensures the stability and accuracy of the connection between slider 2 and slide plate 3, but also realizes the quick replacement of slider 2 of different specifications, so that the guide rail module can adapt to working scenarios with different loads and motion requirements.

[0048] Reference Figures 2-5The bottom of the guide rail body 1 is provided with a storage tank 7, and the top of the guide rail body 1 is provided with a connecting bolt 8, the end of which is threaded to the top of the storage tank 7. The bottom of the storage tank 7 is threaded with a pressure screw 9, and the top of the pressure screw 9 is fixedly connected with a pressure plate 10, which slides inside the storage tank 7. The bottom of the pressure screw 9 is fixedly connected with a pressure hand ring 11, which has an annular design and an anti-slip design on its outer surface. Multiple sealing rings 12 are fixedly connected at equal intervals on the outer side of the pressure plate 10, and the outer surfaces of the multiple sealing rings 12 are in contact with the inner wall of the storage tank 7. A grease inlet 13 is provided in the upper middle part of the rear side of the storage tank 7, and the output end of the grease inlet 13 is connected to the inside of the storage tank 7.

[0049] Specifically, the storage tank 7 at the bottom of the guide rail body 1 is fixed by a connecting bolt 8. The connecting bolt 8 passes through the top of the guide rail body 1 and is threaded at the end to the top of the storage tank 7, forming a stable connection. The storage tank 7 is used to store grease. The grease inlet 13 at the upper rear side is connected to the inside of the tank, and grease can be added to the storage tank 7 through the grease inlet 13.

[0050] The pressure screw 9, which is threaded to the bottom of the storage tank 7, is fixedly connected to the top of the pressure plate 10, which slides inside the storage tank 7. When the pressure hand ring 11 at the bottom of the pressure screw 9 is rotated, the pressure screw 9 moves up and down along the threaded hole at the bottom of the storage tank 7, causing the pressure plate 10 to rise and fall synchronously inside the tank. The pressure hand ring 11 adopts a ring design, and the anti-slip design on the outer surface facilitates the application of rotational force and prevents the hand from slipping during operation.

[0051] The outer surfaces of multiple sealing rings 12, which are fixed at equal intervals on the outer side of the pressure plate 10, are in contact with the inner wall of the storage tank 7. When the pressure plate 10 rises, the sealing rings 12 move synchronously with it, which can prevent the grease in the storage tank 7 from leaking from the gap between the pressure plate 10 and the tank wall, thus ensuring the pressurization effect.

[0052] When the elastic suction tube 54 of the lubrication mechanism 5 draws grease from the storage tank 7, the pressure hand ring 11 is rotated to move the pressure plate 10 upward, applying pressure to the grease in the storage tank 7, which promotes the grease to enter the elastic suction tube 54 more smoothly, providing power to replenish the pump body 51 with grease.

[0053] Grease inlet 13 is used when the grease level in storage tank 7 is insufficient. Grease can be added to the tank by opening grease inlet 13. After adding grease, grease inlet 13 is closed to prevent impurities from entering or grease from overflowing.

[0054] The detachable design of the connecting bolt 8 facilitates the overall disassembly and maintenance of the storage tank 7; the threaded engagement between the pressure screw 9 and the storage tank 7 allows for precise control of the lifting distance of the pressure plate 10, adapting to different grease replenishment needs;

[0055] The storage tank 7 continuously supplies grease, which, together with the pressure screw 9 and the pressure plate 10, ensures that the lubrication mechanism 5 always has sufficient grease for injection. Together with the lubrication mechanism 5, it maintains the lubrication state of the contact area between the guide rail body 1 and the slide plate 3, ensuring the long-term stable operation of the entire guide rail module.

[0056] Working principle: The grooves 4 on both sides of the guide rail body 1 provide a sliding path for the slide pieces 3. The inner flanges of the two slide pieces 3 fit against the inner side of the grooves 4, allowing the slide pieces 3 to slide stably along the top of the guide rail body 1. The slider 2 is connected to the two slide pieces 3 through the replacement mechanism 6 and moves synchronously with the slide pieces 3, driving the external load to complete linear motion. In the replacement mechanism 6, two rubber pads 61 are attached to the front and rear sides of the slider 2. The positioning rod 62 in the middle of the front and rear sides of the slider 2 is inserted into the positioning hole 63 of the slide piece 3 and the rubber pad 61 to achieve precise positioning of the slider 2 and the slide piece 3. The fastening screws 64 on the left and right sides of the outside of the slide piece 3 pass through the slide piece 3 and the rubber pad 61, and the ends are threaded to the front and rear sides of the slider 2. The three are fixed together by the thread fastening force. The rubber pad 61 undergoes slight deformation under pressure, filling the gap and absorbing vibration, enhancing the connection stability.

[0057] When slider 2 and slider 3 slide along slide groove 4, the lubrication mechanism 5 on the left and right sides inside the guide rail body 1 starts to work; the pusher 52 outside the pump body 51 is located inside slide groove 4, and its hemispherical design matches the smooth design of the inner flange of slider 3; when slider 3 slides past pusher 52, the flange contacts and presses pusher 52, causing pusher 52 to retract into pump body 51, driving internal piston 53 to move and squeeze grease inside pump body 51; grease is sprayed out through double-headed nozzle 55 at the output end of pusher 52, evenly covering the contact surface between the inner side of slide groove 4 and slider 3, forming a lubricating layer and reducing sliding friction;

[0058] After the slider 3 slides past the pusher 52, the pusher 52 loses external pressure, and the piston 53 returns to its original position under its own elasticity. New grease is drawn from the storage tank 7 at the bottom of the guide rail body 1 through the elastic suction tube 54 and replenished into the pump body 51, preparing for the next press. The storage tank 7 is fixed to the bottom of the guide rail body 1 by the connecting bolt 8. The grease stored inside is replenished through the grease inlet 13. When the grease inlet 13 is closed, it can prevent impurities from entering or grease from overflowing. When the elastic suction tube 54 draws in grease, the pressure hand ring 11 is rotated to drive the pressure screw 9 to rotate, so that the pressure screw 9 rises along the threaded hole at the bottom of the storage tank 7, pushing the pressure plate 10 to slide inside the tank, applying pressure to the grease and promoting its smooth entry into the elastic suction tube 54. The sealing ring 12 on the outside of the pressure plate 10 fits against the inner wall of the storage tank 7 to prevent grease from leaking from the gap and ensure the pressure effect.

[0059] When it is necessary to replace the slider 2 with a different specification, loosen and remove the fastening screw 64 to separate the slider 3 from the slider 2. The positioning rod 62 is then pulled out from the positioning hole 63, and the rubber pad 61 is removed along with the slider 2. When replacing the new slider 2, align the positioning rod 62 of the new slider 2 with the positioning holes 63 of the slider 3 and the new rubber pad 61, insert it, and then use the fastening screw 64 to fix it through, thus completing the replacement. The cooperation between the positioning rod 62 and the positioning hole 63 ensures that the relative positions of the slider 2 and the slider 3 are consistent after replacement, avoiding affecting the sliding accuracy.

[0060] The amount of grease injected into the lubrication mechanism 5 is related to the sliding frequency of the slider 3. The more frequent the movement, the more injections are required to adapt to different usage intensities. The storage tank 7 continuously replenishes the lubrication mechanism 5 with grease through the pressurization component. The replacement mechanism 6 enables the rapid replacement of the slider 2 to adapt to different load requirements. The coordinated operation of each component enables the guide rail module to automatically complete lubrication and replenishment while achieving stable sliding, improving operating efficiency and maintenance convenience, and ensuring long-term stable operation.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
