Description

Technical Field

[0001] The utility model relates to the field of linear guide pairs, and specifically to a high-life linear guide pair with a lubrication function. Background Technique

[0002] A linear guide pair is composed of a guide rail and a sliding block, and is used in occasions of high-precision or high-speed linear reciprocating motion, and can bear a certain torque. There are circulating rolling balls inside the sliding block, and the sliding block is slidably clamped on the guide rail through the balls. When the linear guide pair operates, noise will be generated by friction between components such as the guide rail, the slider and the balls, and heat will be generated by the mutual friction, resulting in wear, and further greatly reducing the transmission accuracy and processing quality of the equipment, leading to the need for continuous maintenance. Therefore, the Chinese authorized utility model patent (Publication No.: CN218817612U) discloses a linear guide pair with a self-lubrication function. Through the liquid storage tank arranged on the protective shell, the staff can manually pull the pull rod to drive the movable rod to move, so as to release the current limiting of the connecting pipe, so that the lubricating oil in the liquid storage tank flows into the connecting pipe, and the lubricating oil enters the lubricating mechanism to lubricate the connection between the slide rail body and the guide rail body, so as to facilitate the timely addition of lubricating oil and avoid excessive friction from damaging the guide pair.

[0003] However, the above device still has some deficiencies in use: specifically, since the oil injection process requires manual operation, it usually needs to be carried out when the equipment is in a stopped state, which not only affects the continuous operation of the equipment, but also reduces the production efficiency and increases the production cost. Therefore, in view of the above situation, a high-life linear guide pair with a lubrication function is proposed. Content of the Utility Model

[0004] In order to make up for the problem that the oil injection process in the prior art requires manual operation and needs to be carried out when the equipment is in a stopped state, which affects the continuous operation of the equipment, the utility model proposes a high-life linear guide pair with a lubrication function.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a high-life linear guide pair with a lubrication function, including a base, a guide rail is arranged on the base, a sliding block is slidably matched on the guide rail, a flow cavity is arranged on the sliding block, and an oil storage box is arranged on the top of the sliding block.

[0006] An oil injection mechanism is further arranged on the sliding block. The oil injection mechanism includes an oil delivery pipe. The oil delivery pipe has an inner cavity. One end of the oil delivery pipe is communicated with the inside of the oil storage box. The end of the oil delivery pipe away from the oil storage box is communicated with the flow cavity for injecting lubricating oil into the flow cavity. An activity groove is opened at the top of the oil delivery pipe, and the activity groove is communicated with the inner cavity.

A sealing plate is slidably fitted on the outer wall of the block away from the oil storage box. A connecting rod is provided on the top of the sealing plate. The connecting rod is detachably connected to the driving rod after passing through the oil pipeline. A mounting block is provided on the top of the oil pipeline, and a first elastic member is provided in the mounting block. The connecting rod is fixedly connected to the first elastic member.

[0008] The base is provided with a resistance plate, the resistance plate is provided with a through slot, a second elastic member is provided in the through slot, and when the guide rail slides to the maximum stroke of the base, the blocking plate is misaligned with the notch to allow the lubricating oil to flow out.

[0009] Preferably, the oil delivery pipe is in an "L" shape and has two openings, which are connected to the inner cavity for delivering lubricating oil.

[0010] Preferably, an outer wall of the oil storage box is provided with an oil outlet, one of the openings is communicated with the oil outlet, and the other opening is communicated with the port of the flow chamber.

[0011] Preferably, the top of the oil storage box is provided with an infusion hole, and the infusion hole is equipped with a rubber plug.

[0016] The utility model is beneficial in that:

[0017] 1. The utility model adopts the structural design of the block, the blocking plate, the connecting rod, the first elastic member and the contact plate. When the sliding block slides to the maximum stroke, the contact between the driving rod and the contact plate pushes the driving rod to move in the opposite direction, so that the blocking plate slides and is misaligned with the notch, so that the lubricating oil can flow out through the notch into the flow cavity on the guide rail to realize automatic oil filling, which solves the cumbersome steps of the traditional manual oil filling method that requires shutdown operation, thereby improving the continuous operation capability and production efficiency of the equipment;

[0030] A stop block 6 is fixedly connected to the inner wall of the inner cavity 5010. The stop block 6 has a notch 601. A sealing plate 7 is slidably engaged with the outer wall of the stop block 6 on the side far from the oil storage box 4. A connecting rod 8 is arranged on the top of the sealing plate 7. After the connecting rod 8 passes through the oil delivery pipe 501, it is detachably connected to a driving rod 9. An installation block 10 is arranged on the top of the oil delivery pipe 501. A first elastic member 11 is arranged in the installation block 10, and the connecting rod 8 is fixedly connected to the first elastic member 11.

[0031] Wherein, a hollowed - out groove is opened on one side of the installation block 10. The hollowed - out groove is communicated with the activity groove 5011. One side of the inner wall of the hollowed - out groove is fixedly connected to the first elastic member 11. The end of the connecting rod 8 far from the driving rod 9 is slidably engaged in the hollowed - out groove, and the bottom of the connecting rod 8 is slidably engaged with the oil delivery pipe 501.

[0032] A contact plate 12 is arranged on the base 1. A through - groove 1201 is opened on the contact plate 12. A second elastic member 13 is arranged in the through - groove 1201. When the guide rail 2 slides to the maximum stroke of the base 1, the sealing plate 7 is misaligned with the notch 601 to make the lubricating oil flow out.

[0033] In this embodiment, both the first elastic member 11 and the second elastic member 13 can adopt springs.

[0034] Refer to Figure 3 and Figure 4 , the oil delivery pipe 501 is in an "L" shape. The oil delivery pipe 501 has two openings. The openings are communicated with the inner cavity 5010 for transporting lubricating oil. An oil outlet is opened on the outer wall of the oil storage box 4.
