[0002] A blade fixture is a device used to secure and hold cutting tools. It is widely used in machining, metalworking, woodworking, and other fields. Choosing the right blade fixture is crucial to machining efficiency and precision. Different machining requirements may require different types of fixtures.

[0003] However, when installing some annular blades in existing cutting machines, side clamping or bolts are still used for installation. The side clamping method may cause the blade to fall off due to wear caused by high-speed rotation and long-term use of the blade, while the bolts passing through the blade for connection and fixing may cause the bolt threads to loosen, and the blade may break and fracture under high friction. Utility Model Content

[0004] The purpose of the present utility model is to provide an automatically adjustable blade clamp to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an automatically adjustable blade clamp, comprising a connecting seat and a cutting blade, wherein an adjusting portion capable of adapting to the inner diameter of cutting blades of different sizes is provided on the inner side of the connecting seat;

[0006] Among them, the adjustment part includes mounting piece 1, groove, mounting piece 2, interlocking block, control panel, bracket, circular plate, screw, sliding column, arc-shaped slide groove, turning plate, toggle rod, toggle groove, slide groove, slider, support rod, inner clamp, spring, and slide rod. The surface of the connecting seat is fixedly connected to mounting piece 1, and the surface of the connecting seat is provided with a groove.

[0007] Preferably, the inner side of the groove is fixedly connected to the mounting piece 2, and the inner side of the groove is embedded with an engaging block. When the blade clamp is used, the cutting blade is first passed through the connecting seat, and then the engaging block is aligned with the groove and the engaging block is connected to the mounting piece 2 by bolts. Subsequently, the connecting seat is connected to the cutting equipment by bolts and the mounting piece 1, and the engaging block is threadedly connected to the mounting piece 2 by bolts.

[0008] Preferably, the surface of the engaging block is fixedly connected to a control disk, the surface of the control disk away from the engaging block is fixedly connected to a bracket, and the end of the bracket away from the control disk is fixedly connected to a circular plate. The screw is turned to rotate and gradually move away from the circular plate. When the screw moves away from the circular plate, it drives the sliding column in the control disk to slide. The inner side of the circular plate is penetrated by and threaded with a screw.

[0009] Preferably, the screw rod passes through and is rotatably connected to a sliding column, the sliding column passes through the control disk and is slidably connected, and an arc-shaped groove is provided on the surface of the sliding column. Since the shift rod is inserted into the arc-shaped groove provided on the surface of the sliding column, when the sliding column slides in the control disk, the arc-shaped groove will move along with it and will resist the shift rod and shift the shift rod to rotate, so that the shift rod drives the rotating plate to rotate together.

[0010] Preferably, the inner side of the control disk is rotatably connected to a rotating plate, the inner side of the rotating plate is fixedly connected to a shift rod, the shift rod passes through the control disk and is inserted into the inner side of the arc-shaped sliding groove, and a shift groove is provided on the surface of the rotating plate.

[0012] Preferably, the surface of the slider is fixedly connected with a support rod, the support rod passes through the control disk and is slidably connected, and the end of the support rod away from the slider is fixedly connected with an inner clamping block. The slider penetrated and fixedly connected by the slide rod is slidably connected to the slide groove, so that when the slide rod is toggled, it will drive the slider to slide in the slide groove, and the slider will open the inner clamping block arranged in a circumferential array through the support rod, so that the inner clamping block will lock the inner diameter part of the cutting blade. A spring is fixedly connected between the slider and the inner side of the slide groove, and the surface of the slider passes through and is rotatably connected with the slide rod. Since the slide rod passes through the slider and is slidably connected, and the slide rod is inserted into the toggle groove opened on the surface of the rotating plate, the slide rod will be toggled when the rotating plate drives the toggle groove to rotate, and the slide rod passes through the toggle groove.

[0013] Compared with the prior art, the present invention provides an automatically adjustable blade clamp with the following beneficial effects:

[0014] 1. The automatically adjustable blade clamp, when the turn plate rotates, because the slide rod passes through the slider and is slidably connected, and the slide rod is inserted into the toggle groove provided on the surface of the turn plate, so that when the turn plate drives the toggle groove to rotate, the slide rod is toggled, but because the slider passed through and fixedly connected by the slide rod is slidably connected to the slide groove, when the slide rod is toggled, it drives the slider to slide in the slide groove, and the slider will support the inner clamping block arranged in a circumferential array through the support rod, so that the inner clamping block locks the inner diameter part of the cutting blade, and fixing the cutting blade by the tightening method of the inner clamping block can reduce the wear between the cutting blade and the bolt after the cutting blade is directly fixed by the bolt, and due to the recessed part in the middle of the inner clamping block, the risk of the cutting blade falling off by clamping on the side can also be reduced.

[0015] 2.

[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: an automatically adjustable blade clamp, comprising a connecting seat 1 and a cutting blade 3, wherein an adjusting portion 2 capable of adapting to the inner diameter of the cutting blade 3 of different sizes is provided on the inner side of the connecting seat 1;

[0023] Among them, the adjustment part 2 includes a mounting piece 1 21, a groove 22, a mounting piece 23, a fitting block 24, a control panel 25, a bracket 26, a circular plate 27, a screw 28, a sliding column 29, an arc-shaped slide 210, a rotating plate 211, a toggle rod 212, a toggle groove 213, a slide 214, a slider 215, a support rod 216, an inner clamp 217, a spring 218, and a slide rod 219. The surface of the connecting seat 1 is fixedly connected to the mounting piece 1 21, and the surface of the connecting seat 1 is provided with a groove 22. The inner side of the groove 22 is fixedly connected to the second mounting piece 23, and the inner side of the groove 22 is embedded with the embedding block 24. When the blade clamp is used, the cutting blade 3 is first passed through the connecting seat 1, and then the embedding block 24 is aligned with the groove 22 and the embedding block 24 is connected to the second mounting piece 23 by bolts. Then, the connecting seat 1 is connected to the cutting device by bolts and the first mounting piece 21, and the embedding block 24 is threadedly connected to the second mounting piece 23 by bolts. The surface of the embedding block 24 is fixedly connected to the control disk 25. The side surface of the control disk 25 away from the embedding block 24 is fixedly connected to the bracket 26. The end of the bracket 26 away from the control disk 25 is fixedly connected to the circular plate 27. Turning the screw 28 causes the screw 28 to rotate and gradually move away from the circular plate 27. When the screw 28 moves away from the circular plate 27, it drives the sliding column 29 to slide inside the control disk 25. The inner side of the circular plate 27 is penetrated and threaded with the screw 28. The screw rod 28 extends through and is rotatably connected to a sliding post 29. The sliding post 29 extends through the control disk 25 and is slidably connected thereto. An arcuate slot 210 is defined on the surface of the sliding post 29. Because the lever 212 is inserted into the arcuate slot 210, when the sliding post 29 slides within the control disk 25, the arcuate slot 210 moves with it and contacts the lever 212, causing it to rotate, thereby causing the lever 212 to rotate the rotating plate 211. A rotating plate 211 is rotatably connected to the inside of the control disk 25. The lever 212 is fixedly connected to the inside of the rotating plate 211. The lever 212 extends through the control disk 25 and is inserted into the inside of the arcuate slot 210. A toggle slot 213 is defined on the surface of the rotating plate 211. A slot 214 is defined on the inside of the control disk 25. A slider 215 is slidably connected to the inside of the slot 214.The surface of the slider 215 is fixedly connected to a support rod 216, which penetrates the control plate 25 and is slidably connected. The end of the support rod 216 away from the slider 215 is fixedly connected to the inner clamping block 217. Because the slider 215 penetrated and fixedly connected by the slide rod 219 is slidably connected to the slide groove 214, when the slide rod 219 is toggled, the slider 215 is driven to slide in the slide groove 214, and the slider 215 will open the inner clamping block 217 arranged in a circumferential array through the support rod 216, so that the inner The clamping block 217 locks the inner diameter part of the cutting blade 3, and a spring 218 is fixedly connected between the slider 215 and the inner side of the slide groove 214. The surface of the slider 215 is penetrated and rotatably connected with a slide rod 219. Since the slide rod 219 penetrates the slider 215 and is slidably connected, the slide rod 219 is inserted into the toggle groove 213 opened on the surface of the rotating plate 211, so that when the rotating plate 211 drives the toggle groove 213 to rotate, it will toggle the slide rod 219, and the slide rod 219 penetrates the toggle groove 213.

[0024] Based on the above embodiment, when the blade clamp is used, the cutting blade 3 is first passed through the connecting seat 1, and then the engaging block 24 is aligned with the groove 22 and the engaging block 24 is connected to the mounting piece 23 by means of bolts, and then the connecting seat 1 is connected to the cutting equipment by means of bolts and the mounting piece 1 21. At this time, the cutting blade 3 is in an unfixed state, and then the screw rod 28 can be screwed to make the screw rod 28 rotate and gradually move away from the circular plate 27. When the screw 28 moves away from the circular plate 27, it will drive the sliding column 29 to slide in the control disk 25. Since the lever 212 is inserted into the arc-shaped slide groove 210 provided on the surface of the sliding column 29, when the sliding column 29 slides in the control disk 25, the arc-shaped slide groove 210 will move along with it and will conflict with the lever 212 and drive the lever 212 to rotate, so that the lever 212 drives the rotating plate 211 to rotate together, and when the rotating plate 21 When the cam 215 is rotated, the sliding rod 219 passes through the slider 215 and is slidably connected. At the same time, the sliding rod 219 is inserted into the toggle groove 213 provided on the surface of the rotating plate 211. When the rotating plate 211 drives the toggle groove 213 to rotate, the sliding rod 219 is toggled. However, since the slider 215, which the sliding rod 219 passes through and is fixedly connected to, is slidably connected to the slide groove 214, when the sliding rod 219 is toggled, the slider 215 is driven to slide in the slide groove 214. The slider 215 opens the inner clamping blocks 217 arranged in a circumferential array through the support rods 216, so that the inner clamping blocks 217 lock the inner diameter part of the cutting blade 3. The tightening method of the inner clamping blocks 217 to fix the cutting blade 3 can reduce the wear between the cutting blade 3 and the bolt after the cutting blade 3 is directly fixed by the bolt. The concave part in the middle of the inner clamping block 217 can also reduce the risk of the cutting blade 3 falling off by clamping it from the side.

[0025] When the rotating plate 211 rotates, the six groups of inner clamping blocks 217 in the circular array will lock the inner diameter of the cutting blade 3 simultaneously and in equal proportion. Therefore, when fixing the cutting blades 3 with different inner diameters, the inner clamping blocks 217 can fix them, which has a wider range of adaptability.

[0026] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
