DETAILED DESCRIPTION

[0037] 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.

[0038] See also Figure 1-Figure 14 , the present invention provides the following technical solutions:

[0039] Embodiment 1: In order to solve the problem that the linear guide slide cannot adjust the lubrication degree and the lubrication starting point in the past, the following technical solution is provided, specifically, a linear guide slide with a self-lubricating structure, including a base 1, an end support plate 2, an adjustable inertial resistance mechanism and an inertial displacement self-oiling mechanism, both ends of the base 1 are provided with an embedding groove 11, and the end support plate 2 is provided with an embedding block 10, which can be engaged with the embedding groove 11 and is used for positioning when the two ends of the base 1 are respectively connected to the corresponding end support plates 2, the upper surface of the base 1 is provided with a track groove 9, and a support bar 7 is installed in the track groove 9, and the two end support plates 2 are provided with a support bar 7. A motor frame 3 and a lubricating oil tank 4 are respectively provided on the outer side, and a motor 5 is installed on the motor frame 3. The shaft end of the motor 5 is connected to one end of a screw rod 12, and the other end of the screw rod 12 is connected to the side of the end support plate 2 provided with the lubricating oil tank 4 by a bearing. The screw rod 12 threadedly penetrates the moving block 8, and the lower surfaces of both ends of the moving block 8 are slidably connected to the track groove 9 through the track block 15 with which it is integrally structured. The upper surfaces of both ends of the moving block 8 are provided with strip holes 17, and the lower end of the support block 16 is slidably connected in the strip hole 17. An adjustable inertia resistance mechanism is penetrated on the lower end of the support block 16, and the bearing of the adjustable inertia resistance mechanism penetrates the moving block 8.

[0040] The adjustable inertial resistance mechanism includes an adjusting rod 18, a limit block 19 and a spring 20. One end of the adjusting rod 18 is connected to one end of the strip hole 17 by a bearing, and the other end of the adjusting rod 18 is passed through the outer side of the moving block 8. The part of the adjusting rod 18 arranged in the strip hole 17 is movable and passes through the lower end of the support block 16, and the adjusting rods 18 on both sides of the support block 16 are threadedly connected to the limit blocks 19. A spring 20 nested in the outer side of the adjusting rod 18 is arranged between each limit block 19 and the side of the support block 16. The parts of the adjusting rod 18 close to the two ends of the strip hole 17 are provided with threads, and the rotation directions of the two sections of the threads are opposite. The opposite threads are used for the movement of the two limit blocks 19 towards or away from each other when the adjusting rod 18 rotates unidirectionally. In the process of rotating the adjusting rod 18, the two limit blocks 19 can be made to move towards or away from each other, thereby squeezing or stretching. The spring 20 can change the pressure-bearing range of the spring 20, so that when the mass of the component connected to the support block 16 is large, by squeezing the spring 20, the component connected to the support block 16 needs a sufficiently large inertia to make the support block 16 and the moving block 8 slide relative to each other, thereby ensuring that the component moves smoothly, stably and accurately, and can only shift the inertial displacement from the oiling mechanism to lubricate the corresponding position after a setback. When the mass of the component connected to the support block 16 is small, by stretching the spring 20, it is ensured that after a setback, its inertia can shift the inertial displacement from the oiling mechanism (inertia is reflected by F=ma, where m is mass and a is acceleration). The limit block 19 is a rectangular block structure, and its width is consistent with the inner width of the strip hole 17, which is used to limit the limit block 19 so that when the adjusting rod 18 rotates, it can only move along the axis of the adjusting rod 18 but cannot rotate.

[0041] Embodiment 2: In order to solve the problem that the linear guide slide is not provided with a self-lubricating structure in the past, so that it cannot be lubricated in time when a setback that cannot be detected by the naked eye occurs, the following technical solution is provided. Specifically, an inertial displacement self-oiling mechanism is also provided in the strip hole 17, and the upper surfaces of the two end support plates 2 are connected by a cover plate 6.

[0042] The inertial displacement self-oiling mechanism includes a chain group 13, an oil delivery pipe 14, an adjusting rod 21, a toggle block 22, a follower piston rod 23, an oil suction channel 24, a piston hole 25, a spring 26, an oil injection channel 27, an oil passage 1 28, an oil passage 29 and an oil passage 3 30. Two piston holes 25 are vertically symmetrically arranged in each strip hole 17, and one end of the follower piston rod 23 is seamlessly slidably connected in the piston hole 25, and the other end of the follower piston rod 23 is arranged opposite to the corresponding toggle block 22, and the toggle block 22 is threadedly connected to the adjusting rod 21. The piston hole 25 is also connected to the follower piston rod 23 extending therein through the spring 26, and each piston hole 25 is connected with the oil suction channel 24 and the oil injection channel 27. The oil suction channel 24 is L-shaped, and the oil suction channel 24 penetrates to the lower surface of the moving block 8. The two oil suction channels 24 on the same side are connected with the Y-shaped oil delivery pipe 14, and the oil delivery pipe 14 movably penetrates the chain group 13 and is connected with the lubricating oil tank 4. The chain group 13 is arranged above the inner bottom of the base 1, and the end of the chain group 13 close to the moving block 8 is J-shaped. When the moving block 8 moves under the action of the rotation of the screw rod 12, the J-shaped chain group 13 gradually deforms into a U-shape, and the other end of the chain group 13 is connected to the side of the base 1 through a vertical axis frame, and the vertical axis frame is perpendicular to the side of the base 1, and two chain groups 13 are symmetrically arranged in the base 1. The two oil injection channels 27 on the same side constitute a U-shaped structure, and one side of the middle thereof is connected with One end of the oil passage 1 28 and the other end of the oil passage 1 28 pass through the threaded hole on the moving block 8 that is threadedly connected to the screw rod 12. The oil passage 1 28 is also connected to the n-shaped oil passage 2 29, and the oil passage 2 29 passes through the lower end of the track block 15. The oil passage 1 28 is also connected to the inner bottom surface of the strip hole 17 through the oil passage 3 30. The oil passage 1 28, the oil passage 2 29 and the oil passage 3 30 are respectively used to inject lubricating oil into the threaded hole on the moving block 8, the inner bottom surface of the track groove 9 and the inner bottom surface of the strip hole 17. The rotating adjustment rod 21 changes the position of the toggle block 22, thereby changing the relative sliding between the support block 16 and the moving block 8 before contacting the follower piston rod 23. The degree of squeezing the follower piston rod 23 can be changed, so that the setback can be adjusted at what point the oil injection lubrication will start, and the degree of lubrication can be adjusted. In the process of the follower piston rod 23 moving into the piston hole 25, the lubricating oil stored in the piston hole 25 will be squeezed, so that the piston hole 25 transmits oil to the oil passage 1 28, the oil passage 29 and the oil passage 3 30 through the oil injection channel 27, so that the threaded hole on the moving block 8, the inner bottom surface of the track groove 9 and the inner bottom surface of the strip hole 17 can be lubricated, so that the setback can be reduced and the smooth and stable movement of the components can be ensured. The other end of the follower piston rod 23 and the cross-section of the toggle block 22 are both right-angled trapezoids, which can be used to smoothly squeeze the follower piston rod 23 when the toggle block 22 moves.The adjusting rod 21 is composed of an a rod, a b rod and a c rod, wherein the b rod bearing is arranged to penetrate the lower end of the support block 16, and the b rod is arranged directly below the adjusting rod 18, and the a rod and the c rod are respectively arranged to be movably extended into the two ends of the b rod, and the ends of the a rod and the c rod extending into the b rod are both prismatic structures, and both ends of the b rod for the a rod and the c rod to extend into are provided with prismatic grooves that match the prismatic structure, wherein the toggle block 22 is only threadedly connected to the b rod, and the parts of the oil suction channel 24 and the oil injection channel 27 that are connected to the piston hole 25 are respectively provided with a one-way liquid inlet valve and a one-way liquid discharge valve, which are used to make the follower piston rod 23 move in the piston hole 25, so that The oil suction channel 24 delivers the lubricating oil to the piston hole 25 in one direction, and the piston hole 25 delivers the lubricating oil to the oil injection channel 27 in one direction. The support block 16 is an inverted convex structure, and the length of its upper end structure is the same as the width of the moving block 8. The long side length of the toggle block 22 matches the inner width of the strip hole 17. The screw threads set on the outer sides of the two ends of the b rod are also opposite. The long side length of the toggle block 22 matches the inner width of the strip hole 17 and is used to limit the toggle block 22. Through the prismatic structure and the prismatic groove, when the a rod, the b rod and the c rod rotate synchronously, the two toggle blocks 22 can only move closer to or away from each other when they are limited.
