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.
[0031] Reference Figures 1 to 9 This utility model provides a hydrostatic slider assembly for CNC machine tools, comprising a guide rail 1, a first slider 2 slidably connected to the guide rail 1, a mounting plate 3 fixedly connected to the upper surface of the first slider 2, a grease cavity 4 inside the first slider 2, and multiple ball bearings 5 rotatably connected to the inner top of the first slider 2, all of which are movably connected to the upper surface of the guide rail 1. A rotating groove 6 is formed on opposite sides inside the first slider 2, and three rolling wheels 7 are rotatably connected in each rotating groove 6. A rubber ring is fixedly connected to each rolling wheel 7, and one side of each rubber ring is rotatably connected to the guide rail 1. The rubber ring increases friction, making it easier to rotate the rolling wheel 7. The first slider 2 has a rotating cavity 9 inside, and a rotating structure 11 is provided inside the rotating cavity 9. The side of the first slider 2 away from each other has a moving groove 10, and each moving groove 10 is connected to the rotating cavity 9. The side of the first slider 2 away from each other has a quick-release component 12. The side of the first slider 2 has an oil supply groove 8. A grease nipple seat check valve is fixedly connected to the side of the first slider 2. Grease is injected into the grease nipple seat check valve by a grease gun, and then delivered into the grease cavity 4 through the oil supply groove 8, which facilitates the lubrication of multiple balls 5.
[0032] To achieve the cleaning purpose, the rotating structure 11 includes a rotating column 111 rotatably connected to the upper surface of the rotating cavity 9. One end of the rotating column 111 is fixedly connected to the upper surface of one of the rolling wheels 7. A first sprocket 112 is fixedly connected to the upper surface of the rotating column 111. A second sprocket 113 is rotatably connected to the bottom of the rotating cavity 9. A chain 114 is movably mounted on both the second sprocket 113 and the first sprocket 112. A rotating disk 115 is fixedly connected to the upper surface of the second sprocket 113. A rotating column 116 is fixedly connected to the upper surface of the rotating disk 115. Moving blocks 118 are slidably connected in both moving slots 10. Moving rods 117 are fixedly connected to opposite sides of the two moving blocks 118. A sliding groove is provided at the bottom of the moving rod 117. The rotating column 116 is movably connected in the sliding groove. A locking groove is provided on one side of each moving block 118. Each L-shaped fixing rod 119 is movably connected to the guide rail 1. Each L-shaped fixing rod 119 has a snap-fit hole on one side. Each L-shaped fixing rod 119 has a fine brush 1110 fixedly connected to its bottom. When the first slider 2 moves, multiple rolling wheels 7 roll on the guide rail 1. One of the rolling wheels 7 drives the rotating column 111 to rotate. The rotating column 111 drives the first sprocket 112 to rotate. The first sprocket 112 drives the second sprocket 113 to rotate through the chain 114. The second sprocket 113 drives the rotating column 116 to rotate through the rotating disk 115. The rotating column 116 drives two moving blocks 118 to move through the moving rod 117. The moving blocks 118 drive the corresponding L-shaped fixing rod 119 to move. The L-shaped fixing rod 119 drives the fine brush 1110 to move. The fine brush 1110 sweeps away the debris that falls on the guide rail 1, which helps to reduce the probability of the first slider 2 getting stuck due to debris.
[0033] To facilitate the quick replacement of the fine brush 1110, the quick-release assembly 12 includes a fixed frame 121 fixedly connected to one side of the moving block 118. A sliding rod 122 is slidably connected through one side of the fixed frame 121. A locking post 123 is fixedly connected to one end of the sliding rod 122. One end of the locking post 123 is slidably connected through one side of the moving block 118. The locking post 123 is adapted to a corresponding locking hole. A spring 124 is movably mounted on the sliding rod 122. One end of the spring 124 is fixedly connected to one side of the interior of the fixed frame 121, and the other end is fixedly connected to one side of the locking post 123. Pulling the sliding rod 122 causes the locking post 123 to move, disengaging the locking post 123 from the locking hole. Then, the L-shaped fixed rod 119 can be removed, making it convenient for staff to replace the fine brush 1110.
[0034] Working principle: When the first slider 2 moves, multiple rolling wheels 7 roll on the guide rail 1. One of the rolling wheels 7 drives the rotating column 111 to rotate. The rotating column 111 drives the first sprocket 112 to rotate. The first sprocket 112 drives the second sprocket 113 to rotate via the chain 114. The second sprocket 113 drives the rotating column 116 to rotate via the rotating disk 115. The rotating column 116 drives two moving blocks 118 to move via the moving rod 117. The moving blocks 118 drive the corresponding L-shaped fixed rod 119 to move. The L-shaped fixed rod 119 drives the fine brush 1110 to move. The fine brush 1110 sweeps away the debris that falls on the guide rail 1, which helps to reduce the probability of the first slider 2 getting stuck due to debris. Pulling the sliding rod 122 causes the locking post 123 to move, so that the locking post 123 disengages from the locking hole. Then the L-shaped fixed rod 119 is removed, making it convenient for the staff to replace the fine brush 1110.
