A centralized tool fixing structure

Abstract

This utility model discloses a centralized tool fixing structure, including a basic fixture, a slot inside the basic fixture, an adaptive fixture inside the slot, a lathe tool slidably mounted inside the adaptive fixture, a control slot on the adaptive fixture, and a limiting mechanism inside the control slot for quick installation and replacement of the lathe tool. Through the limiting mechanism, when the pressing block is subjected to pressure, it slides along the control slot, thereby driving a connecting rod to rotate. The two ends of the connecting rod are connected to the pressing block and the clamping rod, respectively. Therefore, the rotation of the connecting rod causes the clamping rod to move, gradually moving it away from the lathe tool, thus achieving rapid release of the lathe tool. This mechanism significantly improves the efficiency of tool replacement.

Description

Technical Field

[0001] This utility model relates to the field of tool clamping technology, specifically a centralized tool fixing structure. Background Technology

[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. In the prior art, such as the Chinese utility model patent (publication number: CN216297977U), a cutting tool fixing structure is disclosed, including a basic fixture. A slot is opened in the middle of the front side of the basic fixture, penetrating the front, back and side of the basic fixture. An adjustment mechanism is installed in the slot. A lathe cutting tool is installed in the front side of the adjustment mechanism, penetrating the front and back of the adjustment mechanism. A first threaded hole is opened in the top surface of the basic fixture, penetrating the top surface of the basic fixture and the top surface of the slot wall.

[0003] In the aforementioned prior art, rotating the first bolt on the base fixture causes it to rotate through the first threaded hole in the base fixture until the bottom end of the first bolt is retracted into the base fixture. Moving the adjustment mechanism allows the adaptable fixture to be inserted into the slot. Rotating the first bolt again causes it to rotate through the first threaded hole in the base fixture. The first bolt secures the adjustment mechanism to the base fixture, facilitating the installation and removal of the clamping parts on the tool fixing structure. When the clamping parts on the tool fixing structure are damaged, they can be replaced promptly. However, each time the tool is replaced, multiple bolts must be rotated, which may reduce overall production efficiency. Utility Model Content

[0020] 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.

[0021] This utility model provides a centralized tool fixing structure, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the centralized tool fixing structure includes a base fixture 1, a slot 2 opened inside the base fixture 1, an adaptive fixture 3 set inside the slot 2, a lathe tool 4 slidably installed inside the adaptive fixture 3, a control slot 5 opened on the adaptive fixture 3, and a limiting mechanism set inside the control slot 5 for quick installation and replacement of the lathe tool 4.

[0022] The limiting mechanism includes a pressing block 6 slidably installed inside the control groove 5, a clamping rod 7 slidably installed inside the control groove 5, a connecting rod 8 rotatably installed inside the control groove 5, a first spring 9 disposed inside the control groove 5, and a second spring 10 disposed inside the control groove 5.

[0023] The pressing block 6 passes through the control groove 5, one side of the clamping rod 7 is in contact with one side of the lathe tool 4, one end of the connecting rod 8 is rotatably connected to one side of the pressing block 6, and the other end of the connecting rod 8 is rotatably connected to one side of the clamping rod 7.

[0024] One end of the first spring 9 is fixedly connected to the inner wall of one side of the control groove 5, and the other end of the first spring 9 is fixedly connected to one side of the pressing block 6. One end of the second spring 10 is fixedly connected to one side of the pressing block 6, and the other end of the second spring 10 is fixedly connected to the end of the clamping rod 7 away from the lathe tool 4.

[0025] When using this centralized tool fixing structure, the basic fixture 1 is first installed in a suitable position. Then, the operator applies external force to press the pressing block 6. After being subjected to external force, the pressing block 6 slides along the control groove 5. This sliding action drives the rotation of the connecting rod 8. Since one end of the connecting rod 8 is rotatably connected to the pressing block 6 and the other end is rotatably connected to the clamping rod 7, the rotation of the connecting rod 8 will cause the clamping rod 7 to move accordingly. During the movement, the clamping rod 7 will gradually move away from the side of the lathe tool 4. During this process, the first spring 9 and the second spring 10 are squeezed. Then, the lathe tool 4 is placed in the adaptive fixture 3 to ensure that the position of the lathe tool 4 is correct. Next, the pressing block 6 is released, and the elastic potential energy of the first spring 9 and the second spring 10 restores each part to its initial position until it is tightly attached to the lathe tool 4, thus achieving a stable clamping of the lathe tool 4. When removing the lathe tool 4, it is only necessary to press the two pressing blocks 6 inward, and then the lathe tool 4 can be removed from the inside of the adaptive fixture 3.

[0026] Furthermore, in order to install the adaptive clamp 3 inside the slot 2, such as Figure 1 , Figure 2 and Figure 5 As shown, control blocks 11 are fixedly connected to the top and bottom of the basic fixture 1. A connecting plate 12 is slidably connected inside the control block 11, and the side surface of the connecting plate 12 is in contact with the inner wall of the control block 11.

[0027] A third spring 13 is provided inside the control block 11, and one end of the third spring 13 is fixedly connected to the top inner wall of the control block 11.

[0028] The other end of the third spring 13 is fixedly connected to one side of the control block 11, and the connecting plate 12 is fixedly connected to the side away from the third spring 13 with a plug rod 14, and multiple plug rods 14 are provided.

[0029] The insertion rods 14 are arranged in a linear array on the connecting plate 12. The insertion rods 14 pass through the base clamp 1. The interior of the adaptive clamp 3 has slots 15 for the insertion rods 14 to be inserted.

[0030] When using this centralized tool fixing structure, the adaptable fixture 3 is placed inside the slot 2. At this time, the insertion rod 14 is compressed, which drives the connecting plate 12 to slide inside the control block 11 and compresses the third spring 13 until the insertion rod 14 is fully inserted into the slot 15 of the adaptable fixture 3. At this time, due to the elastic potential energy, the third spring 13 drives the connecting plate 12 to reset. The connecting plate 12 drives the insertion rod 14 to be inserted into the slot 15, realizing the rapid installation of the adaptable fixture 3. The installation process is simple and convenient, and the firmness is good, which improves the work efficiency. At the same time, the insertion rod 14 is distributed in a linear array on the connecting plate 12, which can ensure that the insertion between the insertion rod 14 and the slot 15 is more stable, further improving the firmness of the installation.

[0031] Furthermore, to facilitate the installation of the adaptive fixture 3, such as Figure 1 , Figure 2 and Figure 5 As shown, the adaptive clamp 3 has a guide groove 16 on one side that is adapted to the insertion rod 14.

[0032] When using this centralized tool fixing structure, when installing the adaptive clamp 3, first align the adaptive clamp 3 with the slot 2 and insert it directly. Multiple guide slots 16 first contact the inclined surface of the insertion rod 14. The inclined surface design of the insertion rod 14 allows it to slide smoothly into the guide slot 16 when it contacts the guide slot 16.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
