Description

Technical Field

[0001] This utility model relates to the field of linear guide rail manufacturing technology, and in particular to a linear guide rail with good wear resistance. Background Technology

[0002] A linear guide is a mechanical device used to support and guide moving parts in linear reciprocating motion. It consists of two parts: a guide rail and a slider. The guide rail is fixed to the base of the equipment, while the slider is connected to the moving parts. When the moving parts are subjected to external forces, the slider will move smoothly in a straight line along the guide rail, thereby achieving precise position control and motion transmission.

[0003] With the booming development of modern industry, the performance requirements of manufacturing equipment continue to rise. Especially in the fields of automated production, CNC machine tools and precision instruments, the accuracy and stability of linear motion are crucial. When traditional linear guides undergo high-frequency reciprocating motion, the wear problem becomes increasingly prominent, which requires a linear guide with better wear resistance.

[0004] Currently, a type of linear guide with good wear resistance on the market mainly consists of a guide rail, a slider, and a scraper. During use, by mounting the device on the slider, the slider can move dynamically on the guide rail. However, during use, because the slider needs to move frequently, friction can easily reduce the slider's motion accuracy. To solve this problem, existing technologies often reduce friction between the guide rail and the slider by applying lubricating oil to the guide rail. However, in actual use, due to the frequent movement of the slider, the lubricating oil is prone to dripping, and operators need to frequently apply lubricating oil to the guide rail, increasing the workload of operators and failing to meet the needs of users. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a linear guide with better wear resistance, aiming to improve the problem that existing linear guides with good wear resistance require frequent addition of lubricating oil during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a linear guide rail with good wear resistance, comprising a slide rail, grooves on the left and right rear ends of the slide rail, oil outlet holes on the front ends of adjacent sides of the two grooves, baffles slidably connected to the inner sides of the two grooves, fixing plates fixedly connected to the middle of the opposite sides of the two baffles, a limiting block fixedly connected to the rear end of the slide rail, an inner cavity formed in the lower middle part of the inner side of the limiting block, the rear ends of the two baffles passing through the limiting block and fixedly connected to the same connecting plate, springs fixedly connected to the left and right sides of the inner rear end of the inner cavity, the front ends of the two springs respectively fixedly connected to the left and right sides of the rear wall of the connecting plate, an oil storage cavity formed in the upper middle part of the inner side of the limiting block, a conveying pipe connected to the bottom of the oil storage cavity, the lower end of the conveying pipe passing through the limiting block and the slide rail in sequence and connected to the top of the oil outlet hole, a sliding seat slidably connected to the middle of the outer side of the slide rail, and lifting mechanisms provided on the front and rear sides of the bottom of the slide rail, the lifting mechanisms being used to facilitate keeping the device in a horizontal state.

[0007] As a further description of the above technical solution:

[0008] The lifting mechanism includes a bidirectional threaded rod and a support plate. The two bidirectional threaded rods are rotatably connected to the front and rear sides of the bottom left wall of the slide rail, respectively. The bottom front and rear sides of the slide rail are provided with bottom grooves. The right ends of the two bidirectional threaded rods penetrate the slide rail. The left and right sides of the outer walls of the two bidirectional threaded rods are threaded with first movable clips. The inner sides of the multiple first movable clips are rotatably connected with connecting rods. One end of the multiple connecting rods is rotatably connected with a second movable clip. The bottom ends of the multiple second movable clips are respectively fixedly connected to the top left and right sides of the corresponding support plate.

[0009] As a further description of the above technical solution:

[0010] The sliding seat is fixedly connected to pulley seats on the left, right, front and rear sides of its interior, and movable wheels are rotatably connected to the inner sides of multiple pulley seats.

[0011] As a further description of the above technical solution:

[0012] A knob is fixedly connected to the left end of each of the two bidirectional threaded rods, and the inner dimensions of the bottom groove match the dimensions of the first movable clip.

[0013] As a further description of the above technical solution:

[0014] Mounting holes are provided at the four corners of the top of the sliding seat, and mounting grooves are provided on the left and right sides of the top of the sliding seat.

[0015] As a further description of the above technical solution:

[0016] The top right side of the limiting block is connected to an oil filling port, and an oil filling cap is provided on the top of the oil filling port.

[0017] As a further description of the above technical solution:

[0018] Dustproof plates are provided on both the front and rear sides of the sliding seat. Screws are threaded to the left and right ends of the two dustproof plates on the opposite sides. One end of each screw passes through the corresponding dustproof plate and is threaded to the slide rail.

[0019] As a further description of the above technical solution:

[0020] Both of the fixing plates are fixedly connected to the front side with rubber pads, and the inner size of the sliding seat matches the size of the slide rail.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the sliding seat pushes the fixed plate to move backward, and the baffle moves backward accordingly. At this time, the lubricating oil in the oil tank can enter the interior of the sliding seat through the delivery pipe and the oil outlet to lubricate the slide rail and the moving wheel. When the sliding seat moves forward, the spring drives the baffle to move forward through the connecting plate, which can close the oil outlet, thus realizing automatic lubrication of the slide rail and the moving wheel, reducing the workload of the staff and meeting the needs of the user.

[0023] 2. In this utility model, the knob drives the bidirectional threaded rod to rotate. Since the first movable card is limited by the bottom groove, the first movable card will drive the connecting rod to move. The connecting rod drives the support plate to move through the second movable card. By adjusting the height of the front and rear support plates, the horizontal state of the slide rail can be finely adjusted, reducing the error caused by the tilt of the slide rail and improving the accuracy of the device's movement.

A movable wheel 15 is rotatably connected to the inner side of multiple pulley seats 14. The movable wheel 15 can reduce the friction between the sliding seat 13 and the slide rail 1.

[0035] Reference Figure 1 and Figure 5 The lifting mechanism 2 includes two bidirectional threaded rods 201 and a support plate 206. Two bidirectional threaded rods 201 are rotatably connected to the front and rear sides of the bottom left wall of the slide rail 1, respectively. Bottom grooves 202 are provided on both the front and rear sides of the bottom of the slide rail 1. The right ends of both bidirectional threaded rods 201 penetrate the slide rail 1. First movable catches 203 are threadedly connected to the left and right sides of the outer walls of both bidirectional threaded rods 201. When the bidirectional threaded rods 201 rotate, the first movable catches 203 move accordingly due to the limitation imposed by the bottom grooves 202. Connecting rods 204 are rotatably connected to the inner sides of multiple first movable catches 203. The movement of the first movable catches 203 drives the connecting rods. 204 moves, and one end of each of the multiple connecting rods 204 is rotatably connected to a second movable clip 205. The movement of the connecting rods 204 will drive the second movable clips 205 to move.

[0036] Reference Figure 1 Mounting holes 19 are provided at the four corners of the top of the sliding seat 13, and mounting grooves 20 are provided on the left and right sides of the top of the sliding seat 13. Equipment can be installed on the sliding seat 13 through the mounting holes 19 and mounting grooves 20. The top right side of the limiting block 7 is connected to the oil filling port 21. Lubricating oil can be added to the oil storage chamber 11 through the oil filling port 21. The top of the oil filling port 21 is provided with an oil filling cap 22, which can close the oil filling port 21.

[0037] Reference Figure 1 and Figure 3Dustproof plates 17 are provided on both the front and rear sides of the sliding seat 13. Screws 18 are threaded to the left and right ends of the two dustproof plates 17 on the opposite side. One end of each screw 18 passes through the corresponding dustproof plate 17 and is threaded to the slide rail 1. The dustproof plates 17 are used to prevent dust from entering the inside of the sliding seat 13. The screws 18 are used to remove and install the dustproof plates. Rubber pads 23 are fixedly connected to the front of the two fixing plates 6. The rubber pads 23 can reduce the impact of the sliding seat 13 on the fixing plates 6. The inner size of the sliding seat 13 matches the size of the slide rail 1, so that the lubricating oil is not easy to leak.

[0038] Working principle: When the sliding seat 13 moves backward to a position close to the limit block 7, the sliding seat 13 will push the fixed plate 6 to move backward. When the fixed plate 6 moves backward, it will drive the baffle 5 to move backward. When the baffle 5 moves backward, it will open the oil outlet 4. At this time, the lubricating oil in the oil storage chamber 11 is transported into the oil outlet 4 through the delivery pipe 12, and then enters the interior of the sliding seat 13 from the oil outlet 4 to achieve lubrication of the slide rail 1 and the moving wheel 15. When the sliding seat 13 moves forward, the spring 10 pushes the connecting plate 9 to move forward. The connecting plate 9 then drives the baffles 5 on both sides to move forward, which can close the oil outlet 4, realize the automatic lubrication of the slide rail 1 and the moving wheel 15, and avoid damage to the device due to untimely lubrication.

[0039] Furthermore, during the installation of this device, when the slide rail 1 is not in a horizontal state, turning the knob 16 will cause the bidirectional threaded rod 201 to rotate. Since the first movable clips 203 on both sides are limited by the bottom groove 202, when the bidirectional threaded rod 201 rotates, the first movable clips 203 on both sides will move accordingly. When the first movable clips 203 move, they will drive the connecting rod 204 to move. The movement of the connecting rod 204 will then drive the support plate 206 to move through the second movable clip 205. At this time, by adjusting the height of the front and rear support plates 206, the horizontal state of the slide rail 1 can be finely adjusted, reducing the error caused by the tilt of the slide rail 1.

[0040] 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.
