Detailed Implementation

[0016] Example 1

[0017] like Figures 1 to 3As shown, a machine tool base anti-detachment structure includes a base 1 and an anchor bolt 2. The anchor bolt 2 movably passes through the base 1. Multiple anti-detachment holes 3 are formed along the axial direction of the side wall of the anchor bolt 2. A horizontal hole 4 is formed in the side wall of the base 1. An anti-detachment shaft 5 is slidably disposed within the horizontal hole 4. One end of the anti-detachment shaft 5 is inserted into the anti-detachment hole 3. A locking nut 15 is threaded onto the anchor bolt 2. The locking nut 15 is located above the bearing platform 13. The anchor bolt 2 is passed through the machine tool's base hole and the base 1, and then the anti-detachment shaft 5 is inserted, so that both ends of the anti-detachment shaft 5 are located at the anti-detachment hole 3 and the horizontal hole 4, respectively. The anchor bolt 2 is connected to the pad 1 by inserting it into the hole 4. Then, the locking bolt 15 is tightened until it contacts the machine tool, that is, the locking nut 15 is located above the anchor hole, thus connecting the anchor bolt 2 and the pad 1 to the machine tool, ensuring that they will not fall off during hoisting. Secondly, multiple anti-loosening holes 3 are provided in the axial direction of the anchor bolt 2, which can adjust the pouring depth of the anchor bolt 2. The anti-loosening shaft 5 is inserted into different anti-loosening holes 3, which can adjust the length of the anchor bolt 2 passing through the pad 1, thereby adjusting the pouring depth and making it convenient to adjust the pouring length of the anchor bolt 2 according to the actual pouring situation.

[0018] Example 2

[0019] Based on Example 1, such as Figure 1 and Figure 2 As shown, a spring groove 6 is provided on the side wall of the pad 1. The spring groove 6 is coaxial with the horizontal hole 4. A spring 7 is installed in the spring groove 6. A pull plate 8 is fixed to the end of the anti-detachment shaft 5 away from the anchor bolt 2. The two ends of the spring 7 are respectively connected to the pad 1 and the pull plate 8. When the spring 7 is in its normal state, the anti-detachment shaft 5 is inserted into the anti-detachment hole 3. When it is necessary to adjust the casting length of the anchor bolt 2, the pull plate 8 drives the anti-detachment shaft 5 to move away from the anchor bolt 2, so that the anti-detachment shaft 5 disengages from the anti-detachment hole 3. Then the anchor bolt 2 is moved, and when the casting length of the anchor bolt 2 is adjusted... After the degree adjustment is completed, the position of the anchor bolt 2 is finely adjusted so that the anti-detachment hole 3 corresponds to the anti-detachment shaft 5. Under the reaction force of the spring 7, when the anti-detachment hole 3 corresponds to the anti-detachment shaft 5, the anti-detachment shaft 5 automatically inserts into the anti-detachment hole 3 to complete the limiting of the anchor bolt 2. In specific implementation, a sliding groove is opened on the side wall of the anchor bolt 2 along its own axis, and a limiting block is fixed in the through hole at the bottom of the pad 1. The anchor bolt 2 passes through the through hole, and the limiting block is adapted to the sliding groove, so that the anchor bolt 2 can only move up and down, ensuring that the anti-detachment hole 3 can move smoothly to correspond with the anti-detachment shaft 5.

[0020] Furthermore, the end of the anti-loosening shaft 5 near the anchor bolt 2 is tapered, and its diameter gradually decreases along the direction near the anchor bolt 2, making it easier for the anti-loosening shaft 5 to be inserted into the anti-loosening hole 3. In specific implementation, after the anchor bolt is moved to the designated height, the anti-loosening shaft is inserted. If the anti-loosening shaft cannot be inserted into the correct position, the position of the anchor bolt can be slightly adjusted. During the slight movement of the anchor bolt, force is applied to insert the anti-loosening shaft. When the anti-loosening hole corresponds to the anti-loosening shaft, the anti-loosening shaft can naturally be inserted into the anti-loosening hole. The tapered design of the anti-loosening shaft makes it easier to insert into the anti-loosening hole. Under the guidance of the tapered shape, the anti-loosening shaft is inserted into the correct position, which will naturally move the anchor bolt into place.

[0021] Example 3

[0022] Based on Example 2, such as Figure 1 and Figure 3 As shown, a screw 9 is rotatably installed inside the pad base 1. The screw 9 is located on one side of the anchor bolt 2. A lower wedge block 10 is threaded onto the screw 9. An upper wedge block 11 fits onto the top inclined surface of the lower wedge block 10. A lifting column 12 is connected to the top of the upper wedge block 11. The lifting column 12 moves through the pad base 1 and is connected to a bearing platform 13. The top of the anchor bolt 2 passes through the bearing platform 13, avoiding the anchor bolt 2, and the screw 9 is installed. The lower wedge block 10 is slidably installed inside the pad base 1. By rotating the screw 9... The lower wedge block 10 is moved, and through the cooperation of the inclined surfaces of the lower wedge block 10 and the upper wedge block 11, the upper wedge block 11 drives the bearing platform 13 to move up and down through the lifting column 12, thereby adjusting the support height. A strip-shaped clearance groove 14 is provided through the top of the lower wedge block 10. The strip-shaped clearance groove 14 extends axially toward the screw 9, and the anchor bolt 2 passes through the strip-shaped clearance groove 14. The setting of the strip-shaped clearance groove 14 ensures that the lower wedge block 10 will not interfere with the anchor bolt 2 during the movement.
