Description

Technical Field

[0001] The utility model relates to the technical field of circular saws, in particular to a detachable diamond cutter head for a circular saw. Background Art

[0002] Circular saws equipped with diamond blades have a longer service life, but although diamonds have extremely high hardness, they will still wear out after long-term use, so they need to be replaced regularly. According to the prior art, such as the detachable circular saw diamond blade described in Chinese patent document CN202223429945.4, the disclosed technical solution is to set a limit device, so that the rotation of the control block drives the rotation of the rotating block. When the rotating block rotates, it drives the extrusion block to move in the inner cavity of the extrusion groove. The movement of the extrusion block drives the limit blocks to move closer to each other. The limit device has a limiting effect on the position of the diamond blade.

[0003] According to the disclosed technical solution, in the prior art, the diamond cutter head is fixed to the side of the circular saw by using screws. Therefore, even if a disassembly structure is adopted, multiple bolts still need to be disassembled and installed on the diamond cutter head, resulting in cumbersome replacement steps. Frequent replacement will also cause damage to the bolts and threaded holes used in the diamond cutter head, reducing the stability after subsequent installation. Therefore, the diamond cutter head is not only affected by the wear of the saw teeth, but also by the life of the connecting structure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a detachable circular saw diamond bit to solve the problems raised in the above-mentioned background technology. The present invention adopts a clamping block for docking and linkage connection of the diamond bit body part, which simplifies the disassembly and assembly steps and extends the service life of the connection structure part.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a detachable circular saw diamond segment, comprising a diamond segment body and a cover plate, the diamond segment body comprising a diamond blade and diamond teeth, a docking turntable installed in the middle of the diamond segment body, a transmission frame installed in the middle of the docking turntable, a drive shaft connected to the middle of the transmission frame, a cover plate installed on the outside of the transmission frame, a dynamic balance indicator assembly installed on the surface of the cover plate, and the dynamic balance indicator assembly rests against one side of the diamond segment body.

[0006] Furthermore, one end of the driving shaft is connected to an external motor device, and a receiving groove is provided at the edge of the docking turntable, and a card block is filled in the interior of the receiving groove.

[0007] Furthermore, a magnetic ring is provided inside the docking turntable, the bottom of the receiving groove is aligned with the surface of the magnetic ring, and the clamping block is adsorbed onto the surface of the magnetic ring in an initial state.

[0008] Furthermore, the diamond teeth are arranged at the edge of the diamond blade, and a convex ring is provided on one side of the diamond blade, and the dynamic balance indicating assembly is aligned with the convex ring.

[0009] Furthermore, a plug-in hole is opened on the inner side of the diamond blade, the inner ring diameter of the diamond blade is the same as the edge diameter of the docking turntable, the number of the plug-in holes and the storage slots is the same, and the plug-in holes and the storage slots are evenly distributed on the diamond blade or the docking turntable.

[0010] Furthermore, a handle is installed on the surface of the cover plate, a locking bolt is inserted in the middle of the cover plate, a threaded hole is opened at the end of the drive shaft, and the locking bolt passes through the cover plate and is embedded in the inside of the threaded hole.

[0011] Furthermore, the dynamic balance indicating assembly includes an indicating rod and a spring. A telescopic hole is opened on the surface of the cover plate. The indicating rod is embedded in the telescopic hole. The spring is sleeved on the surface of the indicating rod.

[0012] Furthermore, one end of the indicator rod rests on the surface of the convex ring through the embedded ball, the other end of the indicator rod protrudes outward from the inside of the telescopic hole, and one end of the spring is fixedly connected to the cover plate part.

[0013] Beneficial effects of the utility model:

[0014] 1. The diamond cutter head of the detachable circular saw is directly mounted on the outside of the docking turntable at the end of the drive shaft. During subsequent use, the card block can be directly pushed into the socket hole inside the diamond cutter head body through the high-speed rotation of the side of the docking turntable to realize the docking transmission process. Therefore, the entire disassembly and assembly process does not require the use of screws to fix the diamond cutter head body, avoiding the occurrence of loose connection caused by wear of the connection structure.

[0015] 2. The detachable circular saw diamond segment is provided with a convex ring on the side, and a dynamic balance indicator assembly is installed on the surface of the cover plate. When not started, the diamond segment body can be manually pushed to rotate slowly. Since the block will not be thrown out and plugged in during low-speed rotation, the diamond segment body will be relatively displaced with the dynamic balance indicator assembly, thereby changing the position of the dynamic balance indicator assembly against the side of the diamond segment body. The indicator rod can be used to determine whether the diamond segment body is skewed.

[0016] 3. When removing the diamond cutter head of the detachable circular saw, it is only necessary to control the drive shaft to slowly decelerate to gradually reduce the influence of the centrifugal force. Then, with the help of the magnetic ring inside the docking turntable, the card blocks falling from the top can be adsorbed when it is about to stop rotating. Therefore, when the rotation stops completely, all the card blocks can be automatically disconnected, thereby further improving the efficiency of disassembly and removal.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4The utility model provides a technical solution: a detachable circular saw diamond segment, comprising a diamond segment body 2 and a cover plate 3, wherein the diamond segment body 2 comprises a diamond blade 13 and diamond saw teeth 14, a docking turntable 12 is installed in the middle of the diamond segment body 2, a transmission frame 11 is installed in the middle of the docking turntable 12, a drive shaft 1 is connected to the middle of the transmission frame 11, a cover plate 3 is installed on the outside of the transmission frame 11, a dynamic balance indicator assembly 4 is installed on the surface of the cover plate 3, and the dynamic balance indicator assembly 4 is installed on the surface of the cover plate 3. The scale indicator assembly 4 is against one side of the diamond segment body 2. The detachable circular saw diamond segment is installed on the side of the docking turntable 12. When installing, the cover plate 3 is removed first, and then the diamond segment body 2 can be directly sleeved on the outside of the docking turntable 12. The cover plate 3 is then installed with bolts. At this time, the drive shaft 1 can be directly started, and the docking turntable 12 is driven to rotate by the drive shaft 1. During the slow acceleration process, the docking linkage process of the docking turntable 12 and the diamond segment body 2 is automatically realized.

[0024] In this embodiment, one end of the drive shaft 1 is connected to an external motor device, and a receiving groove 16 is provided at the edge of the docking turntable 12. The interior of the receiving groove 16 is filled with a clamping block 17. A magnetic ring 18 is provided inside the docking turntable 12. The bottom of the receiving groove 16 is aligned with the surface of the magnetic ring 18, and the clamping block 17 is initially adsorbed to the surface of the magnetic ring 18. The diamond cutter head is directly sleeved on the outside of the docking turntable 12 at the end of the drive shaft 1. When it is subsequently used, the clamping block 17 can be directly pushed into the plug-in hole 15 on the inside of the diamond cutter head body 2 by the high-speed rotation of the side of the docking turntable 12, realizing the docking transmission process. Therefore, the entire disassembly and assembly process does not require the use of screws to fix the diamond cutter head body 2, avoiding the occurrence of loose connections due to wear of the connection structure.

[0025] Specifically, there is no completely locked fixed docking structure between the diamond head body 2 and the docking turntable 12. The linkage effect between the two is achieved by rotating the docking turntable 12, which throws the card block 17 inside the storage groove 16 outward under the centrifugal action, so that it can be pressed against the inner side of the diamond blade 13. At this time, since the diamond head body 2 and the docking turntable 12 are not completely connected, there is still relative displacement between the two. Therefore, the card block 17 that has been pressed against the inner side of the diamond blade 13 by centrifugal action will eventually align with one of the plug-in holes 15 on the inner side of the diamond blade 13 as the rotation process progresses, and then pushes the card block 17 into the inside of the plug-in hole 15, thereby achieving the effect of completing the docking linkage between the diamond head body 2 and the docking turntable 12.

[0026] In this embodiment, the diamond serrations 14 are arranged at the edge of the diamond blade 13, and a convex ring 19 is provided on one side of the diamond blade 13. The dynamic balance indicator assembly 4 is aligned with the convex ring 19. A plug-in hole 15 is provided on the inner side of the diamond blade 13. The inner ring diameter of the diamond blade 13 is the same as the edge diameter of the docking turntable 12. The plug-in holes 15 and the receiving slots 16 are the same in number, and the plug-in holes 15 and the receiving slots 16 are evenly distributed on the diamond blade 13 or the docking turntable 12. During disassembly, it is only necessary to control the drive shaft 1 to slowly decelerate to gradually reduce the influence of the centrifugal force. Then, with the help of the magnetic ring 18 inside the docking turntable 12, the block 17 falling from the top can be attracted when it is about to stop rotating. Therefore, when the rotation stops completely, all the blocks 17 can be automatically disconnected, thereby further improving the efficiency of disassembly and removal.

[0027] Specifically, when the diamond segment body 2 needs to be removed, the drive shaft 1 is controlled to rotate slowly. Since the rotation speed affects the centrifugal effect of the block 17 itself, the centrifugal effect decreases after the rotation speed decreases, and the centrifugal force is ultimately unable to throw the block 17 upward. The block 17 can naturally fall after rotating to the top, fall into the interior of the storage groove 16 and be adsorbed by the inner magnetic ring 18. With the slow rotation process, each block 17 can fall into the interior of the storage groove 16 and be adsorbed, which can completely release the linkage effect between the diamond segment body 2 and the docking turntable 12. During the subsequent re-docking, the increase in rotation speed will eventually cause the centrifugal force to be greater than the force generated by the magnetic attraction.

[0028] In this embodiment, a handle 6 is installed on the surface of the cover plate 3, a locking bolt 5 is inserted in the middle of the cover plate 3, a threaded hole 10 is provided at the end of the drive shaft 1, and the locking bolt 5 is embedded in the inside of the threaded hole 10 after passing through the cover plate 3. The dynamic balance indicating assembly 4 includes an indicator rod 8 and a spring 9. A telescopic hole 7 is provided on the surface of the cover plate 3, and the indicator rod 8 is embedded in the inside of the telescopic hole 7. The spring 9 is sleeved on the surface of the indicator rod 8, and one end of the indicator rod 8 is pressed against the surface of the convex ring 19 through the embedded ball, and the other end of the indicator rod 8 protrudes outward from the inside of the telescopic hole 7. One end of the spring 9 is fixedly connected to the cover plate 3. The diamond cutter head is provided with a convex ring 19 on the side, and a dynamic balance indicator assembly 4 is installed on the surface of the cover plate 3. When the diamond cutter head body 2 is not started, the diamond cutter head body 2 can be manually pushed to rotate slowly. Since the block 17 will not be thrown out and plugged in during low-speed rotation, the diamond cutter head body 2 will be relatively displaced with the dynamic balance indicator assembly 4, thereby changing the position of the dynamic balance indicator assembly 4 against the side of the diamond cutter head body 2. The indicator rod 8 can be used to determine whether the diamond cutter head body 2 is skewed. Specifically, by manually pushing the diamond cutter head body 2 to rotate, when the diamond cutter head body 2 is tilted, the indicator rod 8 will produce a telescopic movement inside the telescopic hole 7, thereby determining that the diamond cutter head body 2 is skewed.
