Description

Technical Field

[0001] The utility model relates to the technical field of cutting saw blades, in particular to a diamond-shaped blade head saw blade. Background Art

[0002] At present, the commonly used diamond saw blades are divided into flat and corrugated types. The so-called flat saw blade refers to the two opposite sides of the blade head being a flat structure as a whole. During the cutting process, the two opposite sides of the flat saw blade rub against the cut surface of the cutting object, and the extrusion of the chips generates heat, which is transferred to the matrix, causing thermal stress in the matrix, causing deformation and making the cutting work difficult.

[0003] At present, the utility model with the publication number of CN205521985U proposes a diamond-shaped blade head saw blade, which belongs to the field of cutting inorganic non-metallic materials such as ceramics, stone, concrete, etc., and includes a circular saw blade base, a circular ring-shaped blade head arranged at the outer edge of the saw blade base, and the blade head is provided with diamond-shaped patterns arranged continuously in a period, and grooves are provided on the diamond-shaped patterns. The blade head is provided with grooves, and the setting of the grooves reduces the friction between the blade head and the cutting object, reduces the heat, and can accommodate the powder and debris generated during the cutting process, thereby improving the sharpness and heat dissipation of the saw blade.

[0004] However, this type of saw blade still has some shortcomings when in use: 1. This type of saw blade has strong sharpness and high heat dissipation during cutting, but it has high wear resistance, and the saw blade needs to be replaced frequently during continuous cutting. Since the saw blade is an integrated structure and is installed at one end of the transmission shaft through the cooperation of a chuck and bolts, it is inconvenient to replace; 2. The saw blade is an integrated structure. When the cutter head is worn, the entire saw blade can only be scrapped, while most of the saw blade base is still in good condition, which means that there is a defect of material waste.

[0005] To this end, the utility model provides a diamond-shaped cutter head saw blade. Utility Model Content

[0011] Furthermore, the elastic telescopic rod includes a fixed sleeve and a support spring, the fixed sleeve and the hanging groove are fixedly connected, the support spring is sleeved in the fixed sleeve, and one end of the action rod is sleeved in the positioning sleeve and abuts against the support spring.

[0012] Furthermore, the other end of the action rod is fixedly connected to a limiting rod used in conjunction with one side of the hanging plate.

[0013] Furthermore, the outer fixing sleeve of the limiting rod is provided with a shock-absorbing rubber sleeve.

[0014] The beneficial effects of the utility model are as follows:

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a diamond-shaped cutter head saw blade, including a saw blade base 1, an annular cutter head with a diamond pattern is fixedly arranged on the outer edge of the saw blade base 1, and when the saw blade base 1 rotates, the cutter head can be driven to rotate to realize cutting processing.

[0023] In the present technical solution, a transmission disk 2 is also included. A docking hole 11 with the same aperture as the outer diameter of the transmission disk 2 is opened in the middle of the saw blade base 1. The docking hole 11 and the transmission disk 2 are detachably connected. The detachable connection in this embodiment has the advantage of improving the convenience of replacing the blade head.

[0024] Specifically, the inner wall of the docking hole 11 is fixedly provided with a hanging plate 3 which is evenly distributed in the circumference. In the present embodiment, there are four hanging plates 3. The outer wall of the transmission disk 2 is provided with a hanging groove 4 which is evenly distributed in the circumference and matches the hanging plate 3. One side of the transmission disk 2 is provided with an inlet and outlet 21 which is connected with the hanging groove 4. The inlet and outlet 21 is arranged on the side close to the hanging groove 4. That is to say, when the docking tube 11 is sleeved on the outside of the transmission disk 2 and then twisted, the hanging plate 3 will pass through the inlet and outlet 21 and enter the hanging groove 4. Then, when the transmission disk 2 continues to be twisted, the hanging plate 3 will be hidden in the hanging groove 4. At this time, the hanging groove 4 limits the hanging plate 3.

[0025] A connection hole 22 is provided in the middle of the transmission disc 2, and the connection hole 22 is used for positioning and connecting with the transmission shaft. When the transmission shaft rotates, the transmission disc 2 is driven to rotate, and when the transmission disc 2 rotates, the cutter head is driven to rotate through the hanging groove 4. A locking member 5 for fixing the hanging plate 3 and the transmission disc 2 is also provided on one side of the transmission disc 2. The function of the locking member 5 is to prevent the hanging plate 3 from shaking in the hanging groove 4 in the circumferential direction. By operating the locking member 5, the position limit of the hanging plate 3 can be easily contacted.

[0026] Specifically, the locking member 5 includes an elastic telescopic rod 51 and a shift block 52. The bottom of the elastic telescopic rod 51 is fixedly connected to the bottom of the hanging groove 4. The elastic telescopic rod 51 is opposite to the inlet and outlet 21. One end of the shift block 52 is fixedly connected to one side of the action rod 511 of the elastic telescopic rod 51. When the action rod 511 is compressed, the hanging plate 3 can swing circumferentially in the hanging groove 4. Otherwise, the hanging plate 3 will be limited by the action rod 511. The shift block 52 is an operating member for manually controlling the action of the action rod 511. Specifically, the other end of the action rod 511 is fixedly connected to a limiting rod 5111 used in conjunction with one side of the hanging plate 3. The limiting rod 5111 acts as a cushion block. Preferably, the external fixing sleeve of the limiting rod 5111 is provided with a shock-absorbing rubber sleeve 6. The function of the shock-absorbing rubber sleeve 6 is to facilitate the hanging plate 3 to swing and disengage from the hanging groove 4.

[0027] Furthermore, the elastic telescopic rod 51 includes a fixed sleeve 512 and a support spring 513 . The fixed sleeve 512 is fixedly connected to the hanging groove 4 . The support spring 513 is sleeved in the positioning sleeve 512 . One end of the action rod 511 is sleeved in the positioning sleeve 512 and abuts against the support spring 513 .

[0028] In this embodiment, the width of the hanging groove 4 is equal to the thickness of the hanging plate 3. This arrangement can prevent the hanging plate 3 from axially shaking in the hanging groove 4. The thickness of the hanging plate 3 is less than the thickness of the saw blade base 1.

[0029] Furthermore, the inner wall of the docking hole 11 is provided with circumferentially evenly distributed limiting notches 111, and the outer wall of the transmission disk 2 is fixedly connected with a stopper 23 used in conjunction with the limiting notch 111. When the hanging plate 3 completely enters the hanging groove 4 and abuts against the side of the hanging groove 4 away from the inlet and outlet 21, the stopper 23 abuts against one end of the limiting notch 111. At this time, when the transmission disk 2 rotates, the hanging groove 4 and the stopper 23 can both push the saw blade base 1 to rotate. This arrangement can improve the strength of the transmission to the saw blade base 1.

[0030] Working principle: when the transmission disk 2 rotates during cutting, the hanging groove 4 provides driving force to the hanging plate 3, and the stop block 23 provides driving force to the limiting notch 111, which can drive the entire saw blade base 1 to rotate to complete the cutting function. When the cutter head on the saw blade base 1 is worn, the dial block 52 is manually pressed, and the action rod 511 moves into the positioning sleeve 512. At this time, the limiting plate 5111 will leave the gap between the hanging plate 3 and the hanging groove 4. The saw blade base 1 is manually rotated so that the hanging plate 3 and the inlet and outlet 21 are opposite to each other. The saw blade base 1 can be pulled outward to disengage from the transmission disk 2, thereby realizing the rapid disassembly of the current saw blade base 1. When replacing a new saw blade base 1, just operate in the above-mentioned method and direction.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
