Description

Technical Field

[0001] The present application relates to the technical field of mechanical processing, and in particular to a tool for mechanical processing. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. Machining mainly includes two categories: manual machining and CNC machining. Manual machining refers to the method of processing various materials by mechanical workers manually operating mechanical equipment such as milling machines, lathes, drilling machines and sawing machines. Manual machining is suitable for small-batch and simple parts production. CNC machining refers to machining by mechanical workers using CNC equipment. These CNC equipment include machining centers, turning and milling centers, wire EDM equipment, thread cutting machines, etc. The vast majority of machine shops use CNC machining technology. By controlling the axes of CNC machine tools, materials are automatically removed as required to obtain finely machined workpieces. CNC machining processes workpieces in a continuous manner and is suitable for large-volume, complex-shaped parts. The parts machined by machining have higher overall precision and higher machining efficiency.

[0003] In machining, the cutting tools in the machine tool are an extremely important part. They are tools used for cutting in machining, also known as cutting tools, including drills, blades, grinders, etc., which are used to process the shape and size of the workpiece. Through a variety of cutting tools, different requirements of different workpieces can be processed, thereby improving the efficiency of the entire processing.

[0004] During use, existing machining tools usually come into direct contact with metal workpieces. During long-term use, the tool head will often wear out. If they continue to be used, the machining accuracy of the workpiece will be affected. Therefore, a new tool needs to be replaced. When replacing the tool, the entire tool is usually disassembled and replaced with a new one. However, only the tool head of the entire tool is worn. The cost of replacing the entire tool is high, and the replaced tool cannot be used again, which is a waste. Summary of the invention

[0005] The purpose of the present application is to solve the problem that when replacing existing cutting tools, the entire cutting tool is usually disassembled and replaced with a new one, but only the cutter head of the entire cutting tool is worn, the cost of replacing the entire cutting tool is high, and the replaced cutting tool cannot be used again, which is quite wasteful. The present application provides a cutting tool for machining.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions: A tool for machining includes a tool handle, a support seat is fixed to one end of the tool handle, a mounting seat is fixed to the end of the support seat away from the tool handle, a mounting slot is provided on the mounting seat, a tool head is installed at the end of the tool handle away from the support seat, and a mounting structure is provided between the tool handle and the tool head.

[0007] By adopting the above technical solution, when using the tool, the mounting base is installed on the machine tool, and the machine tool drives the tool to work to achieve processing of the workpiece. The installation structure can facilitate the replacement of the tool head without replacing the entire tool, thereby improving convenience.

[0008] Furthermore, the mounting structure includes a connecting column fixed on the end of the cutter head, a connecting cavity is provided on the inner wall of the knife handle, the connecting column extends into the connecting cavity, a fixing bolt is threadedly connected to the knife handle, a fixing column is installed on one end of the fixing bolt extending into the interior of the knife handle, a fixing groove is provided on the connecting column and is compatible with the fixing column, a movable groove and a movable groove are provided inside the fixed column, the movable groove and the movable groove are connected to each other, and a reinforcement component is arranged inside the movable groove.

[0009] By adopting the above technical solution, when installing the cutter head, the connecting column is inserted into the connecting cavity, and then the fixing bolt is turned in the forward direction to move it toward the position of the connecting cavity. When the fixing bolt moves, it drives the fixing column to move toward the fixing groove. When the end of the fixing column collides with the bottom of the fixing groove, the fixing of the connecting column is completed, and the replacement of the cutter head is realized. The replacement of the cutter head is relatively convenient, and there is no need to replace the entire tool. When the cutter head needs to be disassembled, the fixing bolt is turned in the reverse direction to drive the fixing column to move, so that the fixing column is separated from the fixing groove, and the restriction on the connecting column is released. Then, the connecting column can be pulled out to complete the removal of the cutter head.

[0010] Furthermore, the reinforcement assembly includes a rotating shaft fixed to the inner wall of the movable groove, the rotating shaft is two and symmetrically arranged, the rotating shaft is rotatably connected with a reinforcement rod, the reinforcement rod is in the shape of a "7", and the connecting column is provided with two symmetrically arranged reinforcement grooves, one end of the reinforcement rod extends into the reinforcement groove, the fixing bolt extends into the movable groove and is rotatably connected with a resistance block, the cross-section of the resistance block is trapezoidal, and the end of the reinforcement rod is rotatably connected with a rolling wheel, and the surface of the rolling wheel is in contact with the surface of the resistance block.

[0011] By adopting the above technical solution, when the fixing bolt is tightened, the resistance block is restricted by the movable groove and moves inside the movable groove. At this time, the rolling wheel is resisted by the resistance block, so that the rolling wheel rotates with it. When the rolling wheel rotates, the reinforcement rod is subjected to force. After being subjected to the force, the reinforcement rod will rotate around the rotating shaft, so that the end of the reinforcement rod enters the reinforcement groove, thereby further fixing the connecting column and improving the firmness of the cutter head. When the cutter head is removed, the resistance block moves to drive the reinforcement rod to rotate, so that the reinforcement rod is separated from the reinforcement groove, thereby releasing the restriction of the reinforcement rod on the connecting column.

[0012] Furthermore, a return spring is fixed to the side of the reinforcement rod, and one end of the return spring away from the reinforcement rod is fixedly connected to the knife handle.

[0013] By adopting the above technical solution, when the reinforcement rod is rotated under force during the process of fixing the cutter head, the reset spring will be pulled. When the cutter head is removed, the return spring will pull the reinforcement rod during the movement of the resistance block, and cooperate with the force applied by the resistance block to reset the reinforcement rod.

[0014] Furthermore, a limiting column is fixed to the bottom of the connecting cavity, and a limiting groove matched with the limiting column is formed on the connecting column.

[0015] By adopting the above technical solution, when the connecting column is inserted into the connecting cavity, the limiting column will enter the limiting groove, thereby limiting the connecting column, making the entire tool handle and the connecting column more integrated, improving the fixing effect of the connecting column, and further improving the fixing effect of the tool head.

[0016] Furthermore, two symmetrically arranged limiting springs are fixed inside the limiting column, and limiting blocks are provided at the ends of the limiting springs. The limiting blocks are slidably arranged with the limiting column, and a limiting hole is opened on the inner wall of the connecting cavity, and the limiting hole is adapted to the limiting block.

[0017] By adopting the above technical solution, when the limiting column enters the limiting groove, the connecting column will resist the limiting block, causing the limiting block to shrink, and the limiting block will squeeze the limiting spring when it shrinks. As the connecting column moves, when the limiting hole corresponds to the limiting block, the limiting block and the limiting spring are no longer in conflict. Under the action of the limiting spring, the limiting block is reset and enters the limiting hole. The connecting column can be fixed in advance by structures such as the limiting block, which is more convenient for subsequent fixation, reduces the loosening of the connecting column when the connecting column is fixed later, and improves the fixing effect.

[0018] Furthermore, a connecting groove is provided at the bottom of the movable groove, a connecting rod is fixed to the lower end of the reinforcement rod, a connecting block is fixed to the end of the connecting rod away from the reinforcement rod, and connecting holes adapted to the connecting block are provided on the connecting column and the limiting column.

[0019] By adopting the above technical solution, when the resistance block moves, it will drive the connecting rod to move, and the movement of the connecting rod will drive the connecting block to move, so that the connecting block enters the connecting hole, thereby further fixing the connecting column and improving the fixing effect of the cutter head.

[0020] Furthermore, two symmetrically arranged positioning posts are fixed on the cutter head, a positioning groove matched with the positioning posts is formed on the knife handle, a clamping groove is formed on the positioning post, and the reinforcement rod is located inside the clamping groove.

[0021] By adopting the above technical solution, when installing the cutter head, the positioning column on the cutter head is aligned with the positioning groove on the tool handle, and then installation is performed. During installation, the positioning column enters the positioning groove, and the positioning column cooperates with the positioning groove to achieve positioning installation, thereby improving installation accuracy. At the same time, when fixing the connecting column, the reinforcement rod will enter the slot, and the slot cooperates with the reinforcement rod to restrict the positioning column, thereby further improving the fixing effect of the cutter head.

[0022] In summary, the present application includes at least one of the following beneficial effects: 1. When installing the cutter head, connect the connecting column to the connecting cavity, and by screwing the fixing bolt, drive the fixing column to enter the fixing groove to fix the connecting column, thereby fixing the cutter head. At the same time, in the process of the fixing bolt driving the fixing column to fix the connecting column, the abutment block is restricted by the moving groove and moves inside the moving groove. At this time, the rolling wheel is resisted by the abutment block, so that the rolling wheel rotates with it. When the rolling wheel rotates, the reinforcement rod is stressed. After being stressed, the reinforcement rod will rotate around the rotating shaft, so that the end of the reinforcement rod enters the reinforcement groove. The cutter head can be replaced by the above structure. When the cutter head is damaged, there is no need to replace the entire tool, which reduces the replacement cost and is more convenient. At the same time, the reinforcement rod cooperates with the fixed column and other structures to achieve multi-angle fixation of the connecting column, improve the fixing effect of the connecting column, and thus improve the stability of the cutter head.

[0023] 2. In the present application, when the fixing bolt drives the fixing column and the reinforcement rod to fix the connecting column, when the fixing bolt drives the resistance block to move, the resistance block will drive the connecting rod to move, so that the connecting rod moves inside the connecting groove. When the connecting rod moves, it drives the connecting block to move. The movement of the connecting block will enter the connecting holes on the connecting column and the limiting column to limit the connecting column. The connecting block can further strengthen the integrity between the connecting column and the tool handle, further improve the fixing effect of the tool head, and reduce the loosening phenomenon during use.

[0024] 3. In the present application, when installing the cutter head, the positioning column on the cutter head is aligned with the positioning groove on the tool handle, and then the connecting column is inserted into the connecting cavity. The positioning column cooperates with the positioning groove to achieve positioning installation, so that the limiting hole on the connecting column corresponds to the limiting block on the limiting column, so that the cutter head can be installed more accurately, and when the fixing bolt is tightened, the reinforcement rod will rotate and enter the slot on the positioning column, thereby limiting the positioning column, thereby further limiting the cutter head, and further improving the connection effect between the cutter head and the tool handle.

[0027] The following is combined with Figure 1-7 This application is described in further detail.

[0028] An embodiment of the present application discloses a tool for machining.

[0029] Reference Figure 1 and Figure 2A tool for machining includes a tool handle 1, a support seat 2 is fixed at one end of the tool handle 1, a mounting seat 3 is fixed at the end of the support seat 2 away from the tool handle 1, a mounting groove 4 is opened on the mounting seat 3, a tool head 5 is installed at the end of the tool handle 1 away from the support seat 2, and a mounting structure is arranged between the tool handle 1 and the tool head 5.

[0030] When installing the tool on the machine tool, the mounting seat 3 is inserted into the position where the tool is installed on the machine tool, and the mounting seat 3 is fixed to complete the installation of the tool. When in use, the tool is driven by the machine tool to work, thereby processing the workpiece. When the cutter head 5 is worn and needs to be replaced, the cutter head 5 can be quickly disassembled with the help of the mounting structure. After disassembly, the new cutter head 5 can be quickly replaced without replacing the entire tool, which is more convenient to use.

[0031] Reference Figure 3 and Figure 4 The mounting structure includes a connecting column 6 fixed on the end of the cutter head 5, a connecting cavity 7 is formed on the inner wall of the handle 1, the connecting column 6 extends into the connecting cavity 7, a fixing bolt 8 is threadedly connected to the handle 1, and a fixing column 10 is installed on one end of the fixing bolt 8 extending into the handle 1, a fixing groove 11 adapted to the fixing column 10 is formed on the connecting column 6, a movable groove 17 and a movable groove 18 are formed inside the fixed column 10, the movable groove 17 and the movable groove 18 are connected to each other, and a reinforcement component is arranged inside the movable groove 18.

[0032] Among them, the reinforcement component includes a rotating shaft 14 fixed on the inner wall of the movable groove 18, there are two rotating shafts 14 and they are symmetrically arranged, and a reinforcement rod 12 is rotatably connected to the rotating shaft 14, and the reinforcement rod 12 is in the shape of a "7". Two symmetrically arranged reinforcement grooves 13 are opened on the connecting column 6, one end of the reinforcement rod 12 extends into the reinforcement groove 13, the fixing bolt 8 extends into the movable groove 17 and is rotatably connected to a resistance block 9, and the cross-section of the resistance block 9 is a trapezoidal shape. The end of the reinforcement rod 12 is rotatably connected to a rolling wheel 16, and the surface of the rolling wheel 16 is in contact with the surface of the resistance block 9.

[0033] In addition, a return spring 15 is fixed to the side of the reinforcement rod 12 , and one end of the return spring 15 away from the reinforcement rod 12 is fixedly connected to the knife handle 1 .

[0034] When installing the cutter head 5, insert the connecting column 6 into the connecting cavity 7, and then turn the fixing bolt 8 in the forward direction to move it toward the position of the connecting cavity 7. When the fixing bolt 8 moves, the abutment block 9 is restricted by the movable groove 17 and moves inside the movable groove 17. At this time, the rolling wheel 16 is abutted by the abutment block 9, so that the rolling wheel 16 rotates with it. When the rolling wheel 16 rotates, the reinforcing rod 12 is subjected to force. After being subjected to the force, the reinforcing rod 12 will rotate around the rotating shaft 14. At the same time, when the abutment block 9 moves, it drives the fixing column 10 to move toward the fixing groove 11. When the end of the fixing column 10 abuts against the bottom of the fixing groove 11, the end of the reinforcing rod 12 enters the reinforcing groove 11. 3, and conflicts with the bottom of the reinforcement groove 13 to achieve the installation of the cutter head 5. When the cutter head 5 needs to be replaced, the cutter head 5 is first disassembled. During disassembly, the fixing bolt 8 is screwed in the opposite direction to drive the conflict block 9 to move. When the conflict block 9 moves, the rolling wheel 16 is forced to rotate and drives the reinforcement rod 12 to move so that it is separated from the reinforcement groove 13. At this time, the fixing column 10 is separated from the fixing groove 11, and then the connecting column 6 can be pulled out to complete the disassembly of the cutter head 5. Then, the new cutter head 5 can be installed, thereby completing the replacement of the cutter head 5. When the cutter head 5 is damaged, there is no need to replace the entire tool, and the replacement process of the cutter head 5 is relatively convenient.

[0035] Reference Figure 4 and Figure 5 A limiting column 20 is fixed at the bottom of the connecting cavity 7, and a limiting groove 19 adapted to the limiting column 20 is opened on the connecting column 6.

[0036] Among them, two symmetrically arranged limiting springs 21 are fixed inside the limiting column 20, and a limiting block 22 is provided at the end of the limiting spring 21. The limiting block 22 is slidably arranged with the limiting column 20. A limiting hole 23 is opened on the inner wall of the connecting cavity 7, and the limiting hole 23 is adapted to the limiting block 22.

[0037] When the connecting column 6 is inserted into the connecting cavity 7, the limiting column 20 will enter the limiting groove 19. The limiting column 20 cooperates with the limiting groove 19 to further improve the connection effect between the cutter head 5 and the handle 1. At the same time, when the limiting column 20 enters the limiting groove 19, the limiting block 22 is resisted by the connecting column 6 and will be retracted into the limiting column 20, and the limiting spring 21 will be squeezed. As the connecting column 6 moves, when the limiting hole 23 corresponds to the limiting block 22, the limiting block 22 is no longer resisted. Under the action of the limiting spring 21, the limiting block 22 is reset and enters the limiting hole 23 to limit the connecting column 6. When it is needed When removing the cutter head 5, pull the cutter head 5 so that the connecting column 6 contacts the limiting block 22, so that the contact block 9 is retracted into the limiting column 20, and the connecting column 6 is pulled out and separated from the shank 1. Through the cooperation of the limiting block 22, the limiting spring 21 and other structures, the connecting column 6 can be pre-fixed when inserted into the connecting cavity 7. When the connecting column 6 is fixed with the fixing bolt 8, the loosening of the connecting column 6 can be prevented, which makes it easier to replace the cutter head 5. By further restricting the connecting column 6, the fixing effect of the cutter head 5 can be improved, making the installation of the cutter head 5 more stable.

[0038] Reference Figure 7 A connecting groove 27 is provided at the bottom of the movable groove 17, a connecting rod 28 is fixed to the lower end of the reinforcement rod 12, a connecting block 29 is fixed to the end of the connecting rod 28 away from the reinforcement rod 12, and a connecting hole 30 adapted to the connecting block 29 is provided on the connecting column 6 and the limiting column 20.

[0039] When the fixing bolt 8 drives the resistance block 9 to move, the resistance block 9 will drive the connecting rod 28 to move, and the movement of the connecting rod 28 will drive the connecting block 29 to move. The movement of the connecting block 29 will enter the connecting hole 30 on the connecting column 6 and the limiting column 20, thereby further fixing the connecting column 6, improving the fixing effect of the connecting column 6, and improving the fixing effect of the cutter head 5; when disassembling the cutter head 5, the moving block drives the connecting rod 28 to move, and drives the connecting block 29 to move together, so that it is separated from the limiting column 20 and the connecting column 6, and the restriction of the connecting block 29 on the connecting column 6 is released.

[0040] Reference Figure 2 and Figure 6 Two symmetrically arranged positioning posts 24 are fixed on the cutter head 5 , a positioning groove 25 matching with the positioning posts 24 is provided on the cutter handle 1 , a clamping groove 26 is provided on the positioning post 24 , and the reinforcing rod 12 is located inside the clamping groove 26 .

[0041] When installing the cutter head 5, the positioning column 24 on the cutter head 5 is aligned with the positioning groove 25 on the handle 1, and then the connecting column 6 is inserted into the connecting cavity 7. The positioning column 24 cooperates with the positioning groove 25 to achieve positioning installation, so that the limiting hole 23 on the connecting column 6 corresponds to the limiting block 22 on the limiting column 20, so that the cutter head 5 can be installed more accurately, and when the fixing bolt 8 is turned, the reinforcing rod 12 rotates and enters the slot 26 on the positioning column 24, so as to limit the positioning column 24, thereby further improving the connection effect between the cutter head 5 and the handle 1. When the cutter head 5 needs to be disassembled, the fixing bolt 8 is turned to rotate the reinforcing rod 12, and the reinforcing rod 12 rotates and separates from the slot 26, and then the cutter head 5 is pulled out to separate the connecting column 6 from the handle 1.

[0042] Working principle: When installing the tool on the machine tool, insert the mounting seat 3 into the position where the tool is installed on the machine tool, and fix the mounting seat 3 to complete the installation of the tool. When in use, the tool is driven by the machine tool to work, thereby processing the workpiece; During the long-term use of the tool, when the cutter head 5 is damaged and needs to be replaced, the damaged cutter head 5 needs to be disassembled first. During disassembly, first screw the fixing bolt 8 in the opposite direction to drive the abutment block 9 to move. When the abutment block 9 moves, the rolling wheel 16 is forced to rotate and drive the reinforcement rod 12 to move, so that it is separated from the reinforcement groove 13, and the reinforcement rod 12 will be separated from the slot 26. Then, the cutter head 5 is pulled out so that the connecting column 6 abuts against the limiting block 22, so that the abutment block 9 is received inside the limiting column 20, the connecting column 6 is pulled out and separated from the shank 1, and the disassembly of the cutter head 5 is completed. At this time, the fixing column 10 is separated from the fixing groove 11, and the disassembly of the cutter head 5 is completed. Then, a new cutter head 5 is taken out. , install the new cutter head 5 on the shank 1. During installation, align the positioning column 24 on the cutter head 5 with the positioning groove 25 on the shank 1, and then insert the connecting column 6 into the connecting cavity 7. The positioning column 24 cooperates with the positioning groove 25 to achieve positioning installation. When the connecting column 6 is inserted into the connecting cavity 7, the limiting column 20 will enter the limiting groove 19 at this time. The limiting column 20 cooperates with the limiting groove 19 to further improve the connection effect between the cutter head 5 and the shank 1. At the same time, when the limiting column 20 enters the limiting groove 19, the limiting block 22 is resisted by the connecting column 6 and will be retracted into the limiting column 20, and the limiting spring 21 will be squeezed. As the connecting column 6 moves, when the limiting hole 23 and the limiting spring 21 are in contact with each other, the limiting block 22 will be retracted into the limiting column 20, and the limiting spring 21 will be squeezed. When the control block 22 corresponds, the limiting block 22 is no longer interfered with. Under the action of the limiting spring 21, the limiting block 22 is reset and enters the limiting hole 23 to limit the connecting column 6. When the connecting column 6 is then fixed with the fixing bolt 8, the loosening of the connecting column 6 can be eliminated, which makes it easier to replace the cutter head 5. After the connecting column 6 is inserted into the connecting cavity 7, the fixing bolt 8 is turned forward to move it toward the position of the connecting cavity 7. When the fixing bolt 8 moves, the interference block 9 is restricted by the moving groove 17 and moves inside the moving groove 17. At this time, the rolling wheel 16 is interfered with by the interference block 9, so that the rolling wheel 16 rotates with it. When the rolling wheel 16 rotates, the reinforcing rod 12 is subjected to force to reinforce the reinforcing rod 12. When the rod 12 is subjected to force, it will rotate around the rotating shaft 14. At the same time, when the interference block 9 moves, it will drive the fixed column 10 to move toward the fixed groove 11. When the end of the fixed column 10 conflicts with the bottom of the fixed groove 11, the end of the reinforcement rod 12 enters the reinforcement groove 13 and conflicts with the bottom of the reinforcement groove 13. At the same time, when the fixing bolt 8 drives the interference block 9 to move, the interference block 9 will drive the connecting rod 28 to move. When the connecting rod 28 moves, it will drive the connecting block 29 to move. The connecting block 29 will move and enter the connecting hole 30 on the connecting column 6 and the limiting column 20, thereby further fixing the connecting column 6. By fixing the connecting column 6 at multiple locations and at multiple angles, the installation of the cutter head 5 is achieved, and the fixing effect of the cutter head 5 is better.
