[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] See also Figure 1-3 A dovetail groove adjustment device is provided above a machine tool base 1 and includes a slide 2 and an adjustment mechanism 3 provided on the slide 2. The slide 2 is connected to the mounting surface via bolts 20. A hydraulic cylinder 11 is provided on the outside of the machine tool base 1. The push rod 54 of the hydraulic cylinder 11 is connected to the machine tool base 1 via a connecting seat 12. The hydraulic cylinder 11 is used to push the machine tool base 1 to move back and forth on the bottom of the slide 2. Furthermore, a plurality of processing positions 13 are provided at the bottom of the machine tool base 1. Parts to be processed are provided on the processing positions 13. In this way, the driving action of the hydraulic cylinder 11 on the machine tool base 1 can reliably realize the movement of the processing positions 13, thereby reliably processing the parts on the processing positions 13.

[0030] The adjustment mechanism 3 includes an adjustment block 31, a lateral adjustment screw 32, and a vertical adjustment screw 33. The vertical adjustment screw 33 is used to adjust the vertical height of the adjustment block 31, and the lateral adjustment screw 32 is used to adjust the horizontal position of the adjustment block 31. The side of the adjustment block 31 facing the machine tool base 1 is inclined, and a dovetail angle 4 is formed between the outer wall of the adjustment block 31 and the bottom of the slide 2. One side of the machine tool base 1 is in contact with the outer wall of the adjustment block 31, and the top of the machine tool base 1 is in contact with the bottom of the slide 2. An adjustment mechanism 3 is provided on both sides of the bottom of the slide 2, that is, an adjustment block 31 is provided on both sides of the bottom of the chute. The side of the adjustment block 31 facing the machine tool base 1 is inclined, so that a dovetail angle 4 is formed between the adjustment block 31 and the slide 2. Under the clamping action of the two dovetail angles 4, the position of the machine tool base 1 can be reliably defined, ensuring that the machine tool base 1 can only slide within the dovetail angle 4, thereby improving the movement accuracy of the machine tool base 1.

[0031] One end of the vertical adjustment screw 33 is threaded through the slide 2, and the other end of the vertical adjustment screw 33 is threaded through the adjustment block 31. The vertical adjustment screw 33 is threadedly connected to the slide 2, and to the adjustment block 31. When the vertical position of the adjustment block 31, i.e., the gap between the adjustment block 31 and the slide 2, needs to be adjusted, the vertical adjustment screw 33 can be rotated. Thanks to the threaded connection, the vertical position of the adjustment block 31 can be reliably adjusted. The lateral adjustment screw 32 and the vertical adjustment screw 33 are perpendicular to each other, pass through the vertical adjustment screw 33, and are threadedly connected to each other. When the horizontal position of the adjustment block 31 needs to be adjusted, the lateral adjustment screw 32 is rotated to change the relative position between the lateral adjustment screw 32 and the vertical adjustment screw 33, thereby adjusting the horizontal position of the adjustment block 31.

[0032] The adjustment mechanism 3 is provided with a lubricating oil release unit 5. A receiving groove 311 is provided on the side of the adjustment block 31 facing the machine tool base 1. The lubricating oil release unit 5 is disposed in the receiving groove 311. The lubricating oil release unit 5 includes a movable plate 51, a spring 52, and a sponge block 53. The sponge block 53 is disposed at the notch of the receiving groove 311. The movable plate 51 is disposed at the bottom of the receiving groove 311. One end of the spring 52 is connected to the movable plate 51, and the other end of the spring 52 is connected to the sponge block 53. Lubricating oil is stored between the movable plate 51 and the sponge block 53. The adjustment block 31 is also provided with a threaded hole 312. A push rod 54 is disposed in the threaded hole 312. The push rod 54 is threadedly connected to the threaded hole 312. One end of the push rod 54 contacts the movable plate 51, and the other end of the push rod 54 is located in the threaded hole 312. A hexagonal socket 540 is provided on the end surface of the push rod 54 away from the machine tool base 1. The outer wall of the movable plate 51 is in contact with the inner wall of the receiving groove 311, ensuring that the lubricating oil will not leak from the movable plate 51. An Allen wrench is inserted into the inner hexagonal hole 540, and the push rod 54 is quickly rotated by the Allen wrench. When the push rod 54 continues to rotate toward the receiving groove 311, the movable plate 51 will move toward the sponge block 53. In this way, it can be ensured that the spring 52 is always in a compressed state under the push of the push rod 54, which also ensures that the sponge block 53 can always maintain a state of contact with the machine tool base 1. In this way, the lubricating oil absorbed by the sponge block 53 can be reliably applied to the outer wall of the machine tool base 1, thereby improving the lubrication effect between the adjustment block 31 and the machine tool base 1, and minimizing the wear of the machine tool base 1 during movement.

[0033] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
