[0017] like Figure 1-7 As shown, a high-precision adjustable machine tool slide includes a slide body 1. The slide body 1 has a weight reduction hole 25, which effectively reduces the weight of the slide body 1 itself, saves materials, and thus saves costs.

[0018] The top of the slide body 1 is provided with a first mounting part 2. The first mounting part 2 includes a first mounting surface 3 located on one side of the top of the slide body 1 and a second mounting surface 5 located on the other side. The first mounting part 2 has a stepped structure. The base surface of the first mounting surface 3 and the base surface of the second mounting surface 5 are perpendicular to each other, so that the force on the slide body 1 is more uniform and the stability of operation is enhanced. The first mounting surface 3 and the second mounting surface 5 are slidably connected to the linear rail 28 on the first slide block 26 through the slider 29.

[0019] A first adjustment mechanism is installed on the second mounting surface 5. The first adjustment mechanism includes a boss 6, a limiting plate 7, a first connecting block 8, and a first wedge plate 9. The boss 6 is located on the top of the slide body 1 on one side of the second mounting surface 5. One side of the first connecting block 8 is connected to the first wedge plate 9 by bolts to form an L-shaped structure, and the other side is connected to the side wall of the boss 6 by bolts. The side wall of the boss 6 perpendicular to the second mounting surface 5 is provided with a beveled surface 10. The beveled surface of the first wedge plate 9 is fitted and connected to the beveled surface 10 of the boss 6. The limiting plate 7 is connected to the top of the boss 6 and covers the first wedge plate 9. The limiting plate 7 is set to limit and guide the first wedge plate 9 to ensure the fit between the first wedge plate 9 and the boss 6.

[0020] By adjusting the connection distance between the first connecting block 8 and the boss 6 with bolts, the first wedge plate 9 can be driven to slide on the inclined surface 10 of the boss 6. Based on the principle of inclined plane, when the first wedge plate 9 moves, its inclined surface will generate a corresponding displacement. The slider 29 is installed on the second mounting surface 5 on one side of the first wedge plate 9. By adjusting the position of the first wedge plate 9, the gap between the slider 29 and the upper rail 28 of the first slide block 26 can be changed, thereby achieving precise control of the guiding accuracy.

The multiple force points of the slide body 1 are distributed on different surfaces, the force is more uniform, and the force on the gantry beam linear rail 28 is reduced.

[0022] A second adjustment mechanism is provided on the third mounting surface 12. The second adjustment mechanism includes a second connecting block 15, a second wedge plate 16, and a third wedge plate 17. The third wedge plate 17 is bolted to the third mounting surface 12.

The inclined surface of the second wedge plate 16 is in contact with the inclined surface of the third wedge plate 17. The second wedge plate 16 has several first slots 18, and the third wedge plate 17 has several first screw holes 19. When the second wedge plate 16 and the third wedge plate 17 are in contact, the first screw holes 19 are located in the first slots 18. When connected to the slider 29, the first screw holes 19 and the slide body 1 are connected by bolts passing through the first slots 18 and the first screw holes 19. The first slots 18 are provided to ensure that the first screw holes 19 are always located in the first slots 18 when the second wedge plate 16 moves left and right.

[0023] By adjusting the connection distance between the second connecting block 15 and the slide body 1 with bolts, the second wedge plate 16 can be driven to slide on the third wedge plate 17. Based on the principle of inclined plane, when the second wedge plate 16 moves, its inclined plane will produce a corresponding displacement. The slider 29 is installed on the second wedge plate 16. By adjusting the position of the second wedge plate 16, the gap between the slider 29 and the upper rail 28 of the second slide block 27 can be changed, thereby achieving precise control of the guiding accuracy.

[0024] A third adjustment mechanism is provided on the fourth mounting surface 13. The third adjustment mechanism includes a third connecting block 20, a fourth wedge plate 21, and a fifth wedge plate 22. The fifth wedge plate 22 is bolted to the fourth mounting surface 13. One side of the third connecting block 20 is bolted to the fourth wedge plate 21 to form an L-shaped structure, and the other side is bolted to the slide body 1. The inclined surface of the fourth wedge plate 21 is in contact with the inclined surface of the fifth wedge plate 22. The fourth wedge plate 21 has several second slots 23, and the fifth wedge plate 22 has several second screw holes 24. When the fourth wedge plate 21 and the fifth wedge plate 22 are in contact, the second screw holes 24 are located in the second slots 23. When connected to the slider 29, the second screw holes 24 are connected to the slide body 1 by bolts passing through the second slots 23 and the second screw holes 24. The second slots 23 are provided to ensure that the second screw holes 24 are always located in the second slots 23 when the fourth wedge plate 21 moves up and down.

[0025] By adjusting the connection distance between the third connecting block 20 and the slide body 1 with bolts, the fourth wedge plate 21 can be driven to slide on the fifth wedge plate 22. Based on the principle of inclined plane, when the fourth wedge plate 21 moves, its inclined plane will produce a corresponding displacement. The slider 29 is installed on the fourth wedge plate 21. By adjusting the position of the fourth wedge plate 21, the gap between the slider 29 and the upper rail 28 of the second slide block 27 can be changed, thereby achieving precise control of the guiding accuracy.

[0026] A first fixed baffle 4 is connected to the slide body 1 at the top of the first mounting surface 3. The first fixed baffle 4 is an L-shaped plate, and one side of the first fixed baffle 4 is in contact with the slider 29 on the first mounting surface 3. A second fixed baffle 14 is connected to the bottom of the slide body 1 below the third mounting surface 12 and the fourth mounting surface 13. The second fixed baffle 14 is an L-shaped plate, and one side of the second fixed baffle 14 is in contact with the slider 29 on the third mounting surface 12 and the fourth mounting surface 13. A through groove is provided on the second fixed baffle 14 located below the fourth mounting surface 13 for connecting the third connecting block 20 to the bottom of the slide body 1 through the through groove. The function of setting the first fixed baffle 4 and the second fixed baffle 14 is to make the base surface of the slider 29 fit and fix it with the reference surface of the slide body 1, so as not to produce relative displacement.
