Detailed Implementation

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a positioning disk 1 and a fixing seat 2; the fixing seat 2 is located on the left side of the positioning disk 1, and two tool rods 3 are mounted on the fixing seat 2;

[0020] It also includes: two adjusting blocks 4, each slidably mounted in a groove 5 on the fixed base 2, with an adjusting hole 6 at the right end of each adjusting block 4. The left end of the tool rod 3 is inserted into the adjusting hole 6, and the position of the two tool rods 3 is controlled by the adjusting blocks 4. Several protrusions 18 are provided on the inner wall of the adjusting hole 6, which are engaged with the ends of the tool rods 3 to restrict the insertion position of the tool rods 3. Positioning frames 19 are fixedly fitted onto the ends of the two tool rods 3, and the positioning frames 19 are engaged with the adjusting blocks 4 to restrict the insertion position of the tool rods 3 into the adjusting hole 6; and a bidirectional lead screw 7, which is screwed into the fixed base 2 using bearings. The threads on the bidirectional lead screw 7 are formed by... The two adjustment blocks 4 are arranged in opposite directions from front to back. The adjustment blocks 4 are screwed onto the double-acting screw 7. The position of the two adjustment blocks 4 is controlled by the double-acting screw 7, which is convenient for processing core shanks of different thicknesses. There are several limiting blocks 8, which are respectively movably inserted into the grooves on the inner wall of the adjustment hole 6 and movably inserted into the side wall of the tool rod 3. By inserting the limiting blocks 8 into the side wall of the tool rod 3, the tool rod 3 is restricted within the adjustment hole 6. There are several springs 9, which are respectively sleeved on the limiting blocks 8. The two ends of the springs 9 are respectively connected to the limiting blocks 8 and the inner wall of the adjustment hole 6. The elastic force of the springs 9 is used to temporarily fix the tool rod 3 within the adjustment hole 6. A fixing component 10 is disposed on the adjusting block 4 and is engaged with the limiting block 8. The fixing component 10 includes: a limiting frame 11, which is fixedly sleeved on the adjusting block 4 and has a through groove 12 inside; an adjusting cylinder 20 is disposed through the top surface of the limiting frame 11; hydraulic oil is filled into the limiting frame 11 and the adjusting cylinder 20; protective frames 17 are symmetrically fixedly sleeved on the two adjusting blocks 4, and the limiting frame 11 is located inside the protective frame 17, protecting the limiting frame 11; an adjusting screw 13, which is threadedly connected to the adjusting cylinder 20; and a pressing block 14 is movably disposed inside the adjusting cylinder 20. The annular wall of the adjusting cylinder 4 is engaged with the inner wall of the adjusting cylinder 20. The bottom end of the adjusting screw 13 is screwed onto the extrusion block 14 using a bearing. The position of the extrusion block 14 is adjusted by adjusting the screw 13, thereby adjusting the hydraulic stress of the hydraulic oil.

The position of the abutting rods 15 is controlled by hydraulic pressure, so that the abutting rods 15 restrict the movement of the limiting block 8.

[0021] When using this utility model, the operator first rotates the bidirectional screw 7 according to the thickness of the core shank, causing the adjusting block 4 to move relative to the slide groove 5 until it moves to a suitable position. Then, with the guidance of the protrusion 18, the end of the tool rod 3 is inserted into the adjusting hole 6 until the limiting frame 11 abuts against the adjusting block 4. Then, with the elastic force of the spring 9, the end of the limiting block 8 is inserted into the side wall of the tool rod 3, and the tool rod 3 is temporarily installed on the adjusting block 4. Then, the hand-tightening end of the adjusting screw 13 is rotated, and the adjusting screw 13 causes the pressing block 14 to move in the adjusting cylinder 20. The pressing block 14 presses the hydraulic oil in the adjusting cylinder 20 and the through groove 12. Using the hydraulic force, the contact rod 15 is moved, so that the contact rod 15 contacts the limiting block 8, restricting the position of the limiting block 8, thereby fixing the tool rod 3 on the adjusting block 4.

[0023] The limiting block 8 is inserted into the rod wall of the tool rod 3 by the elastic force of the spring 9, and the position of the limiting block 8 is fixed by the abutment rod 15, thereby fixing the tool rod 3 in the adjustment hole 6, which facilitates the quick replacement of the tool rod 3.

[0024] The fixing component 10 is set up, and the movement of the extrusion block 14 is controlled by adjusting the screw 13. The movement of the abutment rod 15 is controlled by the hydraulic action, so that the abutment rod 15 abuts against the limit block 8, and the position of the limit block 8 is fixed.

[0025] A sealing ring 16 is provided to improve the sealing between the extrusion block 14 and the regulating cylinder 20;

[0026] A protrusion 18 is provided to guide the tool rod 3 and limit its position within the adjustment hole 6.
