Description
Technical Field
[0001] This utility model relates to the field of disassembly technology, specifically a tool for disassembling machine tool push rod hole covers. Background Technology
[0002] In the field of machine tool maintenance and repair, disassembling the ejector pin hole cover is a common but challenging task. Traditional disassembly tools have shown obvious limitations when dealing with hexagonal ejector pin hole covers of different sizes.
[0003] In existing technologies, traditional disassembly tools are often only compatible with one fixed hexagonal size. In some specific machine tool models, the internal hexagonal size of the ejector pin hole cover is not uniform. However, this leads to maintenance personnel having to frequently change tools or try to forcibly disassemble the machine when encountering different sizes of internal hexagonal bolts. This not only reduces work efficiency but may also damage the ejector pin hole cover and the machine tool. In addition, since the internal hexagonal size of traditional disassembly tools is fixed, uniform hexagonal bolts may become slipped after repeated use. This makes it difficult for the originally compatible disassembly tools to disassemble the slipped hexagonal bolts. Therefore, there is an urgent need for a machine tool ejector pin hole cover disassembly tool to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a tool for disassembling the top rod hole cover of a machine tool, so as to solve the problem that the internal hexagonal size of the disassembly tool mentioned in the background art is difficult to adjust.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tool for disassembling a machine tool push rod hole cover, comprising a main tube, a telescopic tube slidably connected to the inner wall of the main tube, a fixed tube rotatably connected to the inner wall of the telescopic tube, a moving rod slidably connected to the inner wall of the fixed tube, and an adjustment component provided at the lower end of the main tube;
[0006] The adjustment assembly includes a mounting box, which is fixedly connected to the lower end of the main tube. A limiting groove is formed on the inner wall of the mounting box, and multiple moving blocks are slidably connected to the inner wall of the limiting groove. A limiting post is fixedly connected to the side wall of each moving block. A rotating plate is provided on the inner wall of the mounting box, and multiple limiting holes are formed at one end of the rotating plate. The inner wall of the limiting hole is movably sleeved with the surface of the limiting post. A limiting box is fixedly connected to the upper end of the telescopic tube, and a limiting component is provided on the inner wall of the limiting box.
[0007] Preferably, the limiting assembly includes two ratchet wheels, both of which are fixedly connected to the surface of the moving rod. Two rotating posts are fixedly connected to the inner wall of the limiting box. The length of the left rotating post is greater than the length of the right rotating post. A pawl is rotatably connected to the surface of each rotating post, and the bottom surface of the pawl abuts against the tooth groove of the ratchet wheel. A spring is fixedly connected to the side wall of the pawl, and the other end of the spring is fixedly connected to the inner wall of the limiting box. Two pushing posts are inserted into the inner wall of the limiting box, and a pressing plate is fixedly connected to the top surface of the two pushing posts. A T-shaped block is inserted into the inner wall of the limiting box, and the top surface of the T-shaped block is fixedly connected to the bottom surface of the pressing plate.
[0008] Preferably, the limiting groove is hexagonal in design, and the inner wall size of the limiting groove matches the protruding end size of the moving block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model discloses a machine tool top rod hole cover disassembly tool. Through the coordinated use of a main body tube, moving blocks, limiting posts, rotating plates, limiting holes, fixing tubes, limiting grooves, and mounting boxes, when encountering hexagonal bolts of different sizes or hexagonal bolts with sliding edges, pressing the pressing plate and turning the rotating block can change the hexagonal size composed of multiple moving blocks. This makes the side walls of the multiple moving blocks fit more closely with the surface of the hexagonal bolt to be disassembled, thereby improving disassembly efficiency and reducing work difficulty.
[0014] 2. The present invention relates to a tool for disassembling a machine tool top rod hole cover. Through the coordinated use of ratchet, pawl, T-block, press plate, push column, spring and limit box, the tool allows the pawl to limit the moving rod when the press plate is pressed to adjust the hexagonal size composed of multiple moving blocks and then the press plate is released. This prevents the moving rod from rotating on the inner wall of the telescopic tube when disassembling the hexagonal bolt, thus avoiding affecting the disassembly efficiency.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] Please see Figure 1-6 The present invention provides a tool for disassembling a machine tool top rod hole cover, including a main tube 1, a telescopic tube 2 slidably connected to the inner wall of the main tube 1, a fixed tube 3 rotatably connected to the inner wall of the telescopic tube 2, a moving rod 4 slidably connected to the inner wall of the fixed tube 3, and an adjustment component provided at the lower end of the main tube 1.
[0024] The adjustment assembly includes a mounting box 5, which is fixedly connected to the lower end of the main tube 1. A limiting groove 6 is provided on the inner wall of the mounting box 5. Multiple moving blocks 7 are slidably connected to the inner wall of the limiting groove 6. A limiting post 8 is fixedly connected to the side wall of the moving block 7. A rotating plate 9 is provided on the inner wall of the mounting box 5. Multiple limiting holes 10 are provided at one end of the rotating plate 9. The inner wall of the limiting hole 10 is movably sleeved with the surface of the limiting post 8. A limiting box 11 is fixedly connected to the upper end of the telescopic tube 2. A limiting component is provided on the inner wall of the limiting box 11.
[0025] Furthermore, the limiting assembly includes two ratchet wheels 12, both of which are fixedly connected to the surface of the moving rod 4. Two rotating posts 13 are fixedly connected to the inner wall of the limiting box 11. The length of the left rotating post 13 is greater than the length of the right rotating post 13. A pawl 14 is rotatably connected to the surface of each rotating post 13. The bottom surface of the pawl 14 abuts against the tooth groove of the ratchet wheel 12. A spring 15 is fixedly connected to the side wall of the pawl 14, and the other end of the spring 15 is fixedly connected to the inner wall of the limiting box 11. Two [unclear - possibly referring to a specific type of device] are inserted into the inner wall of the limiting box 11. The push column 18 has a pressing plate 17 fixedly connected to its top surface. The inner wall of the limiting box 11 is fitted with a T-shaped block 16, the top surface of which is fixedly connected to the bottom surface of the pressing plate 17. The push column 18, spring 15 and ratchet 12 work together to allow the ratchet 14 to limit the moving rod 4 after the pressing plate 17 is pressed down to adjust the hexagonal size composed of multiple moving blocks 7 and the pressing plate 17 is released. This prevents the moving rod 4 from rotating on the inner wall of the telescopic tube 2 when the hexagonal bolt is disassembled.
[0026] Furthermore, the limiting groove 6 is hexagonal in design, and the inner wall size of the limiting groove 6 matches the protruding end size of the moving block 7. The limiting groove 6 restricts the movement range of the moving block 7.
[0027] Furthermore, a rotating block 19 is fixedly connected to one end of the moving rod 4. The rotating block 19 has a polygonal design, which facilitates the rotation of the moving rod 4.
[0028] Furthermore, two screwing blocks 20 are fixedly connected to the surface of the telescopic tube 2. The two screwing blocks 20 are set in a mirror image. The screwing blocks 20 facilitate the rotation of the telescopic tube 2.
[0029] Furthermore, the multiple movable blocks 7 are matched in size and are arranged in a hexagonal shape. The arrangement of the movable blocks 7 facilitates the clamping of the hexagonal sides of the hexagonal bolts that need to be disassembled.
[0030] Working principle: Through the mounting box 5, the lower end of the rotating plate 9 is placed against the top surface of the hexagonal bolt to be disassembled. Then, the pressing plate 17 is pressed down, which pushes the pushing column 18. The pushing column 18 pushes the pawl 14, causing the pawl 14 to rotate around the rotating column 13 and release the limit on the ratchet 12. Then, the rotating block 19 is turned, which drives the moving rod 4 to rotate. The moving rod 4 drives the fixed tube 3 to rotate, which drives the rotating plate 9 to rotate. The rotation of the rotating plate 9, through the limiting columns 8, causes multiple moving blocks 7 to move simultaneously on the inner wall of the limiting groove 6, thereby changing the size of the hexagon formed by the multiple moving blocks 7. This makes the side walls of the multiple moving blocks 7 fit more closely with the surface of the hexagonal bolt to be disassembled, improving disassembly efficiency and reducing work difficulty.
