Description

Technical Field

[0001] The present application relates to the technical field of diamond cutter heads, and more specifically, to a stable diamond cutter head saw blade. Background Art

[0002] Diamond saw blades are cutting tools widely used in machining hard and brittle materials such as concrete, refractory materials, stone, and ceramics.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 2 As shown, the stable diamond head saw blade provided by the embodiment of the present application includes a base 100, a diamond blade 200, a cover plate 300, a fastening bolt 400 and an arc-shaped joint 500, wherein the base 100 is the basic structure of the saw blade, and the diamond head is fixed on the base 100 to form a diamond head saw blade. A socket 110 is provided inside the base 100, and the socket 110 extends in the radial direction of the base 100. A groove 800 is also provided on the upper surface of the base 100, and the groove 800 and the socket 110 are interconnected. In addition, an axial hole 900 extending in the thickness direction of the base 100 is also provided in the middle of the groove 800. The axial hole 900 is also located at the center of the base 100, and the base 100 can be fixed on the driving shaft of the driving device through the axial hole 900.

[0026] A diamond blade 200 is inserted into the insertion hole 110 of the base 100. The first end of the diamond blade 200 extends through the insertion hole 110 and is located outside the base 100. The second end of the diamond blade 200 is located within the groove 800 of the base 100. A cover plate 300 is provided at the groove 800 of the base 100 to seal the opening of the groove 800. Furthermore, the lower surface of the cover plate 300 does not directly contact the upper surface of the diamond blade 200; a predetermined distance exists between them.

[0027] In this embodiment, the cover plate 300 is provided with fastening bolts 400 extending in the thickness direction. The fastening bolts 400 penetrate the cover plate 300 and are connected to the base 100. The cover plate 300 is fixed to the base 100 via the fastening bolts 400. A plurality of arcuate joints 500 are also provided on the wall of the axial hole 900 of the base 100. The arcuate joints 500 are evenly spaced along the circumferential direction on the wall of the axial hole 900. The curvature of the arcuate joints 500 matches the curvature of the wall of the axial hole 900, allowing the arcuate joints 500 to completely conform to the wall of the axial hole 900.

[0028] A connecting rod 600 is also provided at the end of the arc-shaped joint 500. The connecting rod 600 extends radially along the base 100, penetrates the wall of the axial hole 900, and extends to the position of the diamond blade 200. The screw portion of the fastening bolt 400 is provided with a positioning hole 410 that matches the connecting rod 600. The outer diameter of the connecting rod 600 of the arc-shaped joint 500 is adapted to the distance between the cover plate 300 and the diamond blade. Therefore, the connecting rod 600 of the arc-shaped joint 500 can penetrate the wall of the axial hole 900 and be fixed within the positioning hole 410 of the screw portion of the fastening bolt 400. Furthermore, the base 100 can be fixedly connected to the drive shaft of the drive motor through the multiple arc-shaped joints 500 provided in the axial hole 900.

[0029] In the stabilized diamond segment saw blade provided in the embodiment of the present application, by using a fastening bolt 400 to sequentially penetrate the cover plate 300 and the diamond blade 200, and screwing the end of the fastening bolt 400 into the base 100, the diamond blade 200 can be fixed in the insertion hole 110 of the base 100 through the cover plate 300. At the same time, the arc-shaped joint 500 with the connecting rod 600 is inserted into the fastening bolt 400 along the radial direction of the base 100, and the driving shaft of the driving device is inserted into the shaft hole 900 of the base 100, so that the driving shaft can abut against the multiple arc-shaped joints 500 in the shaft hole 900. By adopting the above-mentioned structural design, the arc joint 500 can be fixed in the shaft hole 900 through the driving shaft to ensure that the connecting rod 600 fixedly connected to the arc joint 500 can be inserted into the fastening bolt 400, thereby effectively preventing the fastening bolt 400 from loosening due to vibration during long-term cutting, thereby causing the diamond blade 200 to fall off.

[0030] In some embodiments, the end of the diamond blade 200 is provided with an L-shaped portion 700, which can be connected to the lower surface of the cover plate 300 via the L-shaped portion 700, thereby providing support. In addition, the connecting rod 600 connected to the arc-shaped joint 500 passes through the vertical portion of the L-shaped portion 700 and extends into the position of the fastening bolt 400.
