[0019] S4: After the lubricating liquid is discharged to the outer wall of the guide rail, wipe the entire outer surface of the guide rail with a sponge to spread it evenly.

[0020] The beneficial effects of the present invention are as follows:

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, in an embodiment of the present invention, a linear guide rail with a refueling mechanism comprises a guide rail 1, a slider 2 is slidably mounted on the outer wall of the guide rail 1, and refueling assemblies are mounted on both sides of the slider 2;

[0034] Among them, the refueling assembly includes a refueling plate 3 installed on the side wall of the slider 2, a cleaning assembly is arranged inside the refueling plate 3, a liquid storage cavity 4 is opened inside the refueling plate 3, and a ball 5 is rotatably installed inside the liquid storage cavity 4, and the ball 5 is arranged in multiple groups.

[0035] By setting the oiling assembly, when working, the slider 2 slides on the outer wall of the guide rail 1, the outer wall of the ball 5 contacts and rubs against the outer wall of the guide rail 1 and rotates, and the lubricating oil inside the liquid storage chamber 4 is applied to the outer wall of the guide rail 1, which helps to reduce wear and extend the service life of the guide rail 1.

[0036] like Figure 4 and Figure 5 As shown, an air bag 8 is installed inside the liquid storage chamber 4 , and the air bag 8 is arranged on one side of the ball 5 .

[0037] The airbag 8 can undergo a certain deformation inside the liquid storage chamber 4 .

[0038] like Figure 4 and Figure 5 As shown, a spring pad 9 is fixedly installed on one side of the airbag 8, a spring 10 is installed on the side wall of the spring pad 9, and one end of the spring 10 away from the spring pad 9 is connected to the liquid storage chamber 4.

[0039] The lubricating oil is arranged in the chamber between the airbag 8 and the ball 5;

[0040] The elastic potential energy of the spring 10 makes the airbag 8 always have a tendency to move toward one side of the ball 5, so that the airbag 8 squeezes the lubricating oil toward one side of the ball 5 to assist in the discharge of the lubricating oil.

[0041] like Figures 1 to 7 As shown, sponges 7 are provided on both sides of the ball 5 , and the sponges 7 are fixedly mounted on the inner wall of the refueling plate 3 .

[0042] After lubrication, wiping the entire outer surface of the guide rail 1 with the sponge 7 can not only remove excess lubricating oil and prevent oil accumulation or leakage caused by excessive lubrication, but also help the lubricating oil to be more evenly distributed on the surface of the guide rail 1, thereby improving the lubrication effect.

[0043] like Figures 1 to 7 As shown, the cleaning assembly includes a rotating wheel 11 arranged inside the refueling plate 3, and the interior of the rotating wheel 11 is evenly arranged with tooth blocks 12 in a ring array, one side of the tooth block 12 is meshingly connected with a rack plate 13, and the rack plate 13 is fixedly installed on the side wall of the guide rail 1, and a reciprocating screw 14 is fixedly installed on the top of the rotating wheel 11. The outer wall of the reciprocating screw 14 is threadedly connected with a piston rod 15, and the top of the piston rod 15 is fixedly installed with a piston 16. The piston 16 is slidably arranged inside a connecting pipe 17, one side of the connecting pipe 17 is fixedly connected with an air inlet pipe 18, and the outer wall of the top of the connecting pipe 17 is evenly installed with an air outlet pipe 20.

[0044] By setting the cleaning component, when the slider 2 slides on the outer wall of the guide rail 1, the movement of the slider 2 drives the movement of the refueling plate 3, the movement of the refueling plate 3 drives the movement of the liquid storage chamber 4, the movement of the liquid storage chamber 4 drives the movement of the rotating wheel 11, the movement of the rotating wheel 11 drives the movement of the tooth block 12, the tooth block 12 engages with the rack plate 13 to rotate, so that the rotating wheel 11 rotates, the rotation of the rotating wheel 11 drives the reciprocating screw 14 to rotate, the rotation of the reciprocating screw 14 drives the piston rod 15 to move up and down reciprocatingly, the movement of the piston rod 15 drives the movement of the piston 16, and the external air is drawn into the connecting pipe 17 through the air inlet pipe 18, and finally discharged from the air outlet pipe 20 and sprayed to the outer wall of the guide rail 1, so as to avoid the accumulation of dust, chips or other tiny impurities on the surface of the guide rail 1 during operation. If these impurities remain on the guide rail 1, it will not only affect the application effect of the lubricating oil, but also may aggravate the wear of the guide rail 1. Blowing air to the surface of the guide rail 1 can effectively remove these impurities and dust, and provide a cleaner surface for subsequent lubrication work.

[0045] like Figure 2 and Figure 3 As shown, the outer walls of the connecting pipe 17 and the air inlet pipe 18 are both installed with a one-way valve 19 .

[0046] like Figure 2 and Figure 3 As shown, the air outlet pipe 20 is arranged at an angle.

[0047] The air outlet pipe 20 is inclined toward the side away from the liquid storage chamber 4 and toward the moving direction of the slider 2, which helps to blow away impurities and dust attached to the surface of the guide rail 1 when the slider 2 moves.

[0048] like Figure 3 and Figure 6 As shown, the tooth block 12 is rotatably mounted inside the rotating wheel 11 via the second rotating shaft 21 , and a torsion spring 22 is mounted on the outer wall of the second rotating shaft 21 .

[0049] A sliding groove is provided inside the rotating wheel 11 for the gear block 12 to rotate, and one side of the gear block 12 is inclined;

[0050] The gear blocks 12 in the refueling assembly on both sides of the slider 2 are engaged with the rack plate 13 and rotated during the movement of the slider 2, and the other gear block 12 is rotated under force to the inside of the rotating wheel 11 and does not rotate, so that the air outlet pipe 20 always sprays and cleans toward the side where the slider 2 moves;

[0051] When the tooth block 12 rotates to the inside of the rotating wheel 11, the rotation of the tooth block 12 drives the rotation of the second rotating shaft 21. The rotation of the second rotating shaft 21 causes the torsion spring 22 to deform and store elastic potential energy, and then release the elastic potential energy to reset.

[0052] like Figure 4 and Figure 5 As shown, each group of balls 5 are fixedly connected via a first rotating shaft 6, and each first rotating shaft 6 is transmission-connected via a third pulley group 26, wherein a second pulley group 25 is mounted at the bottom end of one of the first rotating shafts 6, a third rotating shaft 24 is mounted at one end of the second pulley group 25 away from the first rotating shaft 6, a first pulley group 23 is mounted at the bottom end of the third rotating shaft 24, and an end of the first pulley group 23 away from the third rotating shaft 24 is mounted on the outer wall of the reciprocating screw 14.

[0053] When the reciprocating screw 14 rotates, the rotation of the reciprocating screw 14 drives the third rotating shaft 24 to rotate through the transmission of the first pulley set 23, and the rotation of the third rotating shaft 24 drives the first rotating shaft 6 to rotate through the transmission of the second pulley set 25, thereby driving the ball 5 to rotate, so that the ball 5 continues to rotate and lubricate, preventing the ball 5 from not rotating or rotating insufficiently when contacting the guide rail 1, thereby affecting the lubrication effect and the overall performance of the system.

[0054] A refueling method for a linear guide rail having a refueling mechanism comprises the following steps:

[0055] S1: During operation, the slider 2 slides on the outer wall of the guide rail 1, and the movement of the slider 2 drives the movement of the refueling plate 3, and the movement of the refueling plate 3 drives the movement of the liquid storage chamber 4, and the movement of the liquid storage chamber 4 drives the movement of the rotating wheel 11, and the movement of the rotating wheel 11 drives the movement of the tooth block 12, and the tooth block 12 meshes with the rack plate 13 to rotate so as to rotate the rotating wheel 11, and the rotation of the rotating wheel 11 drives the reciprocating screw rod 14 to rotate, and the rotation of the reciprocating screw rod 14 drives the piston rod 15 to move up and down reciprocatingly, and the movement of the piston rod 15 drives the movement of the piston 16, and the external gas is drawn into the connecting pipe 17 through the air inlet pipe 18, and finally discharged from the air outlet pipe 20 and sprayed to the outer wall of the guide rail 1;

[0056] S2: When the reciprocating screw 14 rotates, the rotation of the reciprocating screw 14 drives the third rotating shaft 24 to rotate through the transmission of the first pulley set 23, and the rotation of the third rotating shaft 24 drives the first rotating shaft 6 to rotate through the transmission of the second pulley set 25, thereby driving the ball 5 to rotate and driving the lubricating liquid in the liquid storage chamber 4 to be discharged;

[0057] S3: At the same time, the elastic potential energy of the spring 10 makes the airbag 8 always have a tendency to move toward one side of the ball 5, so that the airbag 8 squeezes the lubricating oil toward one side of the ball 5 to assist in the discharge of the lubricating oil;

[0058] S4: After the lubricating liquid is discharged to the outer wall of the guide rail 1, the entire outer surface of the guide rail 1 is wiped with the sponge 7 to spread it evenly.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
