Description

Technical Field

[0001] This utility model relates to the field of circular saw blade technology, specifically a multifunctional combined anti-vibration and anti-shake circular saw blade. Background Technology

[0002] Circular saw blades are the most common cutting tools in cutting equipment. They are a general term for various types of circular tools. With market demand, circular saw blades are now widely used and can be used in many cutting devices. Among them, combination circular saw blades are also widely used.

[0003] In the prior art, such as Chinese Patent Publication No. CN216462194U, a circular saw blade for metal cutting is disclosed, including a circular saw blade body, a circular array of saw teeth arranged in a ring, a central hole penetrating through the upper middle part of the circular saw blade body, four mounting holes arranged in a ring array at the upper end of the circular saw blade body, a number of shock-absorbing holes at the upper end of the circular saw blade body, and a heat dissipation device arranged on the upper side of the circular saw blade body.

[0004] The aforementioned patented technology can effectively reduce the radiation intensity of noise by setting several shock-absorbing holes on the circular saw blade body. However, since the saw teeth and the circular cutter head are directly fixed together, when the saw teeth wear out after a long period of use, the entire circular saw blade needs to be replaced, which increases the cost of using the circular saw blade. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multifunctional combined anti-vibration and anti-shake circular saw blade, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a multifunctional combined anti-vibration and anti-shake circular saw blade, comprising a circular cutter disc and saw teeth. The surface of the circular cutter disc has an opening. Two positioning blocks are fixedly installed on the surface of the circular cutter disc. Two protrusions are fixedly installed at the rear end of the circular cutter disc. Four slots are formed on the inner wall of the saw teeth. Through holes are formed on the surface of the saw teeth. A turntable is rotatably mounted on the surface of the circular cutter disc. A limit ring is fixedly connected to the side of the turntable. A push plate is fixedly installed on the surface of the turntable. A push rod is fixedly installed at the rear end of the turntable. Four cavities are formed inside the circular cutter disc. Limit grooves are formed on both sides of the inner wall of each cavity. Movable locking plates are slidably installed inside each of the four cavities. Fixed sliders are fixedly installed at both ends of the movable locking plates. A spring is fixedly connected to the bottom of the movable locking plates. A stabilizing block is fixedly installed on the side of the circular cutter disc.

[0007] Preferably, the movable plate is disposed inside the cavity and its top extends outward to the outer end of the circular cutter head; the fixed slider is slidably installed inside the limiting groove; and the bottom of the first spring is fixedly installed inside the cavity.

[0008] Preferably, the two positioning blocks are symmetrically arranged on both sides of the limiting ring, the limiting ring is rotatably installed inside the positioning blocks, and the push rod is slidably installed inside the opening.

[0009] Preferably, the surface of the movable plate is provided with a guide groove, and one end of the push rod extends into the guide groove.

[0010] Preferably, the number of through holes is the same as the number of stabilizing blocks and they are arranged accordingly. Fitting grooves are provided on both sides of the inner wall of each through hole, and the shape of the stabilizing block matches the shape of the through hole.

[0011] Preferably, the stabilizer block has two storage slots inside, and each of the two storage slots has a sliding plate slidably installed inside, and a spring is fixedly installed inside the sliding plate.

[0012] Preferably, the sliding plate extends slidably to the outside of the stabilizing block, the side of the sliding plate is fixedly connected to the side of the second spring, and the shape of the outer end of the sliding plate matches the shape of the fitting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the movable plate and spring cooperate to lift the movable plate upward and embed it into the slot, thereby connecting and fixing the saw blade to the circular cutter head. Through the cooperation of the push rod and the guide groove, rotating the turntable can push the movable plate downward and move it. The top of the movable plate can fall out of the slot to separate the saw blade from the circular cutter head, thus allowing the saw blade to be disassembled and replaced separately, reducing production costs.

[0015] 2. In this utility model, the stabilizing block, by being installed inside the through hole, can improve the stability of the connection between the saw blade and the circular cutter head, and can disperse the shearing force of the saw blade on the movable plate. The sliding plate abuts against the inside of the fitting groove, and through the action of the second spring, can absorb and buffer the vibration generated by the circular saw blade during cutting, thereby reducing the noise generated by the circular saw blade during the cutting process.

[0023] 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.

[0024] Example 1

[0025] like Figures 1-6As shown, this utility model provides a technical solution: a multifunctional combined anti-vibration and anti-shake circular saw blade, including a circular cutter head 1 and saw blades 2. The surface of the circular cutter head 1 has an opening 101. Two positioning blocks 11 are fixedly installed on the surface of the circular cutter head 1. Two protrusions 12 are fixedly installed at the rear end of the circular cutter head 1. The inner wall of the saw blades 2 has four slots 201. The surface of the saw blades 2 has through holes 202. A turntable 3 is rotatably installed on the surface of the circular cutter head 1. A limit ring 31 is fixedly connected to the side of the turntable 3. A push plate 32 is fixedly installed on the surface of the turntable 3. A push rod 33 is fixedly installed at the rear end of the turntable 3. The interior of the circular cutter head 1 has four cavities 102. Limit grooves 103 are formed on both sides of the inner wall of each cavity 102. Movable clamping plates 4 are slidably installed inside each cavity 102. Fixed sliders 41 are fixedly installed at both ends of the movable clamping plates 4. A spring 42 is fixedly connected to the bottom of the movable clamping plates 4. A stabilizing block 5 is fixedly installed on the side of the circular cutter disc 1. The movable clamping plates 4 are set inside the cavity 102, and their top extends outward to the outer end of the circular cutter disc 1. The fixed sliders 41 are slidably installed inside the limiting groove 103. The bottom of the spring 42 is fixedly installed inside the cavity 102. Two positioning blocks 11 are symmetrically arranged on both sides of the limiting ring 31. The limiting ring 31 is rotatably installed inside the positioning blocks 11. The push rod 33 is slidably installed inside the opening 101. A guide groove 401 is opened on the surface of the movable clamping plates 4. One end of the push rod 33 extends into the guide groove 401.

[0026] In this embodiment, the push plate 32 on the surface of the turntable 3 facilitates the rotation of the turntable 3, while the protrusion 12 at the rear end of the circular cutter disc 1 facilitates the gripping and support of the circular cutter disc 1. The positioning block 11 installed on the side of the limiting ring 31 can fix the position of the limiting ring 31. Furthermore, since the push rod 33 is installed inside the opening 101, it can prevent the turntable 3 from falling off the surface of the circular cutter disc 1. The top of the movable clamping plate 4 is embedded in the slot 201 of the saw blade 2, which can fix the saw blade 2 on the surface of the circular cutter disc 1. The guide groove 401 is angled upwards, so that when the push rod 33 slides inside the guide groove 401, it can pull down and retract the movable plate 4 into the cavity 102. The fixed slider 41 on the surface of the movable plate 4 slides inside the limiting groove 103, which can ensure the stability of the movable plate 4 during the up and down movement. The spring 42 can make the movable plate 4 reset itself when the press is released, so that the saw blade 2 can be easily disassembled and assembled from the surface of the circular cutter head 1, so that the saw blade 2 and the circular cutter head 1 can be used together.

[0027] Example 2

[0028] like Figures 1-6As shown, the number of through holes 202 is the same as the number of stabilizing blocks 5 and they are set accordingly. The inner walls of the through holes 202 are provided with fitting grooves 203 on both sides. The shape of the stabilizing block 5 matches the shape of the through holes 202. The stabilizing block 5 has two storage grooves 501 inside. The two storage grooves 501 are slidably installed with sliding plates 51 inside. The sliding plates 51 are fixedly installed with springs 52 inside. The sliding plates 51 slide to the outside of the stabilizing block 5. The side of the sliding plates 51 is fixedly connected to the side of the springs 52. The shape of the outer end of the sliding plates 51 matches the shape of the fitting grooves 203.

[0029] In this embodiment, when the saw blade 2 is rotating to cut an object, there is a large shearing force between the saw blade 2 and the movable clamping plate 4, which makes the movable clamping plate 4 easy to break and cannot be reused. The stabilizing block 5 installed inside the through hole 202 can disperse the shearing force generated by the saw blade 2, thereby improving the stability of the connection between the saw blade 2 and the circular cutter head 1. The sliding plate 51 is embedded in the fitting groove 203, and the second spring 52 connects and supports the sliding plate 51, so that some of the vibration generated by the saw blade 2 during the cutting process is transmitted to the second spring 52 through the sliding plate 51 for absorption and buffering, thereby reducing the vibration noise generated when the circular saw blade is cutting.

[0030] Working principle: The saw blade 2 is connected and fixed to the circular cutter head 1 through a sleeve. When the circular saw blade is used to rotate and cut an object, there is a large shearing force between the saw blade 2 and the movable clamping plate 4. The stabilizing block 5 is installed inside the through hole 202 to disperse the shearing force generated by the saw blade 2. Some of the vibration generated by the saw blade 2 during the cutting process is transmitted to the spring 2 52 through the sliding plate 51 for absorption and buffering, thereby reducing the vibration noise generated by the circular saw blade during cutting. When the saw blade 2 is damaged and needs to be replaced, hold the protruding block 12 with one hand and rotate the push plate 32 with the other hand to make the turntable 3 rotate. The disc 3 drives the push rod 33 to rotate. The push rod 33 slides inside the guide groove 401, pushing and pulling the movable plate 4 downward. This causes the movable plate 4 to move down and compress the spring 42. The top of the movable plate 4 moves down and retracts into the cavity 102. Its top detaches from the slot 201. At this time, the saw blade 2 can be removed from the surface of the circular cutter disc 1 by pushing it horizontally. A new saw blade 2 is then replaced and reattached to the surface of the circular cutter disc 1. The stabilizing block 5 is then embedded in the through hole 202. Then, the disc 3 is released, causing the spring 42 to rebound. The movable plate 4 resets and moves to fix the saw blade 2 again. This allows for convenient and quick disassembly and replacement of damaged saw blades.
