Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining equipment technology, and in particular to a cutting tool with an anti-vibration tool holder. Background Technology
[0002] Machining equipment refers to a general term for machines and devices that use mechanical methods to process various raw materials, blanks or semi-finished products so that their shape, size, relative position and properties meet specific technical requirements. Among them, the cutting tool of the anti-vibration tool holder is a combination of tools used for cutting processing, which combines the characteristics of the anti-vibration tool holder.
[0003] In traditional tool design, a single-head structure is usually adopted. When the tool head is damaged such as wear or chipping during processing, the operation of the equipment must be stopped immediately for tool head maintenance, which affects the continuity of processing. After the machine is stopped to replace the tool head, when the equipment is restarted, its operating status may not immediately reach the optimal level, and it takes a certain amount of time to adjust and stabilize, which affects processing efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that traditional cutting tool designs often use a single cutting head, which requires machine stoppage for maintenance when worn or damaged, affecting the continuity of processing. To this end, we propose a cutting tool with an anti-vibration tool holder.
[0005] To achieve the above objectives, this application adopts the following technical solution: a cutting tool for an anti-vibration cutter bar, comprising a device platform, a first sliding frame fixedly connected to the top of the device platform, a second sliding frame slidably connected inside the first sliding frame, a clamping device installed at the top of the device platform, a tool holder fixedly connected to one end of the second sliding frame, two mounting slots opened at the bottom of the tool holder, an anti-vibration cutter bar body installed inside the mounting slots, a cutter head installed at the bottom of the anti-vibration cutter bar body, circular slots opened on both sides of the anti-vibration cutter bar body, a first spring fixedly connected inside the circular slots, a connecting block fixedly connected to the other end of the first spring, and circular through slots opened on both sides of the mounting slots, a push rod slidably connected inside the circular through slots.
[0006] Preferably, dovetail grooves are provided at both ends of the mounting groove, and dovetail blocks are fixedly connected to both ends of the anti-vibration knife rod body, with the surface of the dovetail blocks engaging with the interior of the dovetail grooves.
[0007] Preferably, a limiting piece is fixedly connected to the surface of the connecting block, and the surface of the limiting piece is slidably connected to the inside of the circular groove.
[0008] Preferably, a second spring is slidably connected to the surface of the push rod, one end of the second spring is fixedly connected to one side of the push rod, and the other end of the second spring is fixedly connected to one side of the circular groove.
[0009] Preferably, the top and bottom of the push rod surface are provided with sliding grooves, and the top and bottom of the circular through groove side are fixedly connected with sliding blocks, the surface of the sliding blocks being slidably connected to the inside of the sliding groove.
[0010] Preferably, a rubber pad is installed on the surface of the anti-vibration knife bar body.
[0011] Preferably, a baffle is fixedly connected to the bottom of the tool holder, and both sides of the baffle are semi-circular.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, by pressing the push rods on both sides of the mounting slot, the push rods push the connecting block out of the circular through slot. At this time, the anti-vibration tool holder body moves out of the mounting slot, and the connection between the anti-vibration tool holder body and the tool holder is released. At this time, the tool head connected to the anti-vibration tool holder body can be maintained. When reinstalling the anti-vibration tool holder body, press the connecting block to move it into the circular slot, and place the anti-vibration tool holder body into the mounting slot. The elasticity of the first spring automatically pushes the connecting block into the circular through slot, connecting the anti-vibration tool holder body to the tool holder. By installing two tool heads at the bottom of the tool holder, when one tool head is damaged, it can be quickly switched to the other intact tool head to continue processing without stopping the machine. This seamless switching method greatly reduces the production downtime caused by tool head damage, allowing the processing process to continue continuously and stably, thereby significantly improving the overall production efficiency and ensuring that production tasks can be completed on time and efficiently.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: a cutting tool for an anti-vibration cutter bar, including a platform 1, a first sliding frame 2 fixedly connected to the top of the platform 1, a second sliding frame 3 slidably connected inside the first sliding frame 2, a clamping device 4 installed at the top of the platform 1, a tool holder 5 fixedly connected to one end of the second sliding frame 3, two mounting slots 6 opened at the bottom of the tool holder 5, an anti-vibration cutter bar body 7 installed inside the mounting slots 6, a cutter head 8 installed at the bottom of the anti-vibration cutter bar body 7, circular slots 9 opened on both sides of the anti-vibration cutter bar body 7, a first spring 10 fixedly connected inside the circular slots 9, a connecting block 11 fixedly connected to the other end of the first spring 10, circular through slots 12 opened on both sides of the mounting slots 6, a push rod 13 slidably connected inside the circular through slots 12, by pressing the push rods 13 on both sides of the mounting slots 6, the push rods 13 push the connecting block 11 out from inside the circular through slots 12, at this time the anti-vibration cutter... The tool holder body 7 is removed from the inside of the mounting slot 6, and the connection between the anti-vibration tool holder body 7 and the tool holder 5 is released. At this time, the tool head 8 connected to the anti-vibration tool holder body 7 can be maintained. When reinstalling the anti-vibration tool holder body 7, press the connecting block 11 and press the connecting block 11 into the inside of the circular slot 9. Place the anti-vibration tool holder body 7 into the inside of the mounting slot 6. The elasticity of the first spring 10 automatically pushes the connecting block 11 into the inside of the circular through slot 12, so that the anti-vibration tool holder body 7 is connected to the tool holder 5. By installing two tool heads 8 at the bottom of the tool holder 5, when one of the tool heads 8 is damaged, it is possible to quickly switch to the other intact tool head 8 to continue the processing operation without stopping the machine. This seamless switching method greatly reduces the production downtime caused by the damage of the tool head 8, so that the processing process can be carried out continuously and stably, thereby significantly improving the overall production efficiency and ensuring that the production task can be completed on time and efficiently.
[0022] Reference Figure 3 and Figure 4As shown in this embodiment: dovetail grooves 14 are provided at both ends of the mounting groove 6, and dovetail blocks 15 are fixedly connected to both ends of the anti-vibration tool bar body 7. The surface of the dovetail block 15 is engaged with the inside of the dovetail groove 14. By engaging the dovetail block 15 with the dovetail groove 14, the anti-vibration tool bar body 7 can be more stable inside the mounting groove 6, and the anti-vibration tool bar body 7 can be prevented from shaking inside the mounting groove 6.
[0023] Reference Figure 4 As shown in this embodiment: the surface of the connecting block 11 is fixedly connected to the limiting piece 16, and the surface of the limiting piece 16 is slidably connected to the inside of the circular groove 9. By setting the limiting piece 16, the movement position of the connecting block 11 can be restricted, so as to prevent one end of the connecting block 11 from coming out of the inside of the circular groove 9 due to the elasticity of the first spring 10, thus ensuring the stability of the connection between the anti-vibration tool holder body 7 and the tool holder 5.
[0024] Reference Figure 5 As shown in this embodiment: a second spring 17 is slidably connected to the surface of the push rod 13. One end of the second spring 17 is fixedly connected to one side of the push rod 13, and the other end of the second spring 17 is fixedly connected to one side of the inside of the circular through groove 12. By setting the second spring 17, the elasticity of the second spring 17 can drive the push rod 13 to automatically reset without the user having to manually pull it to reset. At the same time, it restricts the movement of the push rod 13 and avoids displacement of the push rod 13 due to vibration caused by the start-up of the equipment.
[0025] Reference Figure 5 As shown in this embodiment: sliding grooves 18 are provided at the top and bottom of the surface of the push rod 13, and sliding blocks 19 are fixedly connected to the top and bottom of one side of the circular through groove 12. The surface of the sliding block 19 is slidably connected to the inside of the sliding groove 18. By making the sliding block 19 slide inside the sliding groove 18, the movement of the push rod 13 can be made more stable, and unnecessary displacement of the push rod 13 during movement can be avoided.
[0026] Reference Figure 4 As shown in this embodiment, a rubber pad 20 is installed on the surface of the anti-vibration tool bar body 7. By setting the rubber pad 20, the rubber pad 20 covers the gap between the anti-vibration tool bar body 7 and the mounting groove 6, which can effectively prevent metal debris from entering the interior of the mounting groove 6.
[0027] Reference Figure 2 and Figure 5As shown in this embodiment: a baffle 21 is fixedly connected to the bottom of the tool holder 5. Both sides of the baffle 21 are semi-circular. By setting the baffle 21, when the equipment is processing, when the operator removes the anti-vibration tool holder body 7 for maintenance, the baffle 21 can effectively block the debris and prevent the debris from touching the operator's hands. The semi-circular design of the baffle 21 ensures that the debris is effectively guided to a safe area and reduces the possibility of splashing.
[0028] Working principle: By pressing the push rods 13 on both sides of the mounting slot 6, the push rods 13 push the connecting block 11 out of the circular through slot 12. At this time, the anti-vibration tool holder body 7 moves out of the mounting slot 6, and the connection between the anti-vibration tool holder body 7 and the tool holder 5 is released. At this time, the tool head 8 connected to the anti-vibration tool holder body 7 can be maintained. When reinstalling the anti-vibration tool holder body 7, press the connecting block 11 to push it into the circular slot 9, and place the anti-vibration tool holder body 7 into the mounting slot 6. The elasticity of the first spring 10 automatically pushes the connecting block 11 into the circular through slot 12. The anti-vibration tool holder body 7 is connected to the tool holder 5. Two tool heads 8 are installed at the bottom of the tool holder 5. When one tool head 8 is damaged, the machine can be quickly switched to the other intact tool head 8 to continue machining without stopping. This seamless switching method greatly reduces production downtime caused by tool head 8 damage, allowing the machining process to continue continuously and stably, thus significantly improving overall production efficiency and ensuring that production tasks are completed on time and efficiently. The dovetail block 15 and dovetail groove 14 are engaged to make the anti-vibration tool holder body 7 more stable inside the mounting groove 6, preventing... The anti-vibration tool holder body 7 vibrates inside the mounting groove 6. The limiting piece 16 restricts the movement of the connecting block 11, preventing one end of the connecting block 11 from detaching from the circular groove 9 due to the elasticity of the first spring 10. This ensures the stability of the connection between the anti-vibration tool holder body 7 and the tool holder 5. The second spring 17 automatically resets the push rod 13 without requiring manual resetting by the user. It also restricts the movement of the push rod 13, preventing displacement due to vibrations during equipment startup. The sliding block 19 is positioned within the sliding groove 18. The internal sliding mechanism makes the movement of the push rod 13 more stable, avoiding unnecessary displacement of the push rod 13 during movement. By setting the rubber pad 20, the rubber pad 20 covers the gap between the anti-vibration cutter body 7 and the mounting groove 6, which can effectively prevent metal chips from entering the interior of the mounting groove 6. By setting the baffle 21, when the anti-vibration cutter body 7 is removed for maintenance during equipment processing, the baffle 21 can effectively block the chips and prevent the chips from touching the workers' hands. The semi-circular design of the baffle 21 ensures that the chips are effectively guided to a safe area, reducing the possibility of splashing.
