Description

Technical Field

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

[0002] Saw blades are a general term for thin circular tools used to cut solid materials. Saw blades can be divided into: diamond saw blades for cutting stone; high-speed steel saw blades for cutting metal materials (without inlaid carbide blade heads); carbide saw blades for cutting solid wood, furniture, artificial boards, aluminum alloys, aluminum profiles, radiators, plastics, plastic steel, etc. Diamond saw blade products in the prior art are all used for a single purpose, i.e. cutting, and do not have a grinding function. In actual processing operations, if grinding is required, it must be replaced with a grinding diamond grinding disc product for operation, resulting in low operating efficiency and high manufacturing costs.

[0003] Patent CN217020012U proposes a dual-purpose cutting and grinding diamond saw blade, wherein a diamond saw blade cutting surface and a diamond saw blade grinding surface are arranged on two opposite surfaces of the saw blade body, the diamond saw blade cutting surface is provided with a strip groove, and the diamond saw blade grinding surface is provided with an arc groove, by dividing the upper and lower surfaces of the cutting diamond-like saw blade into a cutting surface and a grinding surface, the grinding surface is made into a structural form with the same function as the grinding diamond-like saw blade through a special process, and the cutting surface continues to maintain the form of the cutting diamond-like saw blade, and the grinding surface and the cutting surface can act simultaneously to cut during cutting, and the grinding is completed by a separate grinding surface during grinding, wherein the grinding surface divides the diamond cutter head agglomeration into regular diamond grinding cutter heads by setting symmetrical and regular arc grooves to reduce the grinding resistance, and the arc grooves are interconnected to form a debris discharge channel, thereby realizing the grinding function on the diamond cutting functional saw blade, and cutting and grinding operations can be performed separately without changing tools, thereby improving the working efficiency.

[0004] The above scheme sets the two sides of the saw blade as the diamond saw blade cutting surface and the diamond saw blade grinding surface respectively. The disadvantage of this scheme is that it is inconvenient to separate and install the diamond saw blade cutting surface and the diamond saw blade grinding surface. In addition, the diamond saw blade grinding surface is close to the diamond saw blade cutting surface, which easily causes the blade end of the diamond saw blade cutting surface to wear during grinding. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a dual-purpose cutting and grinding diamond saw blade to solve the problems raised in the above-mentioned background technology. The utility model has a novel structure. The grinding disc is installed in the mounting groove of the saw blade body through a locking assembly, which facilitates the disassembly, replacement and installation of the grinding disc. The grinding disc is driven to move outward by the flat head screw of the locking assembly, and then the grinding disc can be protruded out of the mounting groove, thereby preventing the blade end of the saw blade body from being worn.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a dual-purpose cutting and grinding diamond saw blade, including a saw blade body, a mounting groove is provided on one side of the saw blade body, and a locking assembly is provided inside the mounting groove, a grinding disc is installed on the surface of the locking assembly, and mounting holes are provided at the center of the saw blade body and the grinding disc, the locking assembly includes a bottom ring, and two cross plates are fixed on the periphery of the bottom ring, two slots are provided on the back side of the grinding disc, and the cross plates can be inserted along the slots, an outer ring is rotatably sleeved on the outer end surface of the mounting hole, and the outer ring and the bottom ring are fixedly installed and can rotate along the outer wall of the mounting hole.

[0007] Furthermore, two groups of slots are provided inside the grinding disc, and the slots are connected to the innermost side of the slot, and the transverse plate can be rotatably inserted into the slots.

[0008] Furthermore, the locking assembly also includes a fixing plate, and the fixing plates are fixed on both sides of the outer ring, and the bottom of the fixing plate is fixed to the bottom ring.

[0009] Furthermore, the mounting hole is provided with sliding grooves on both sides perpendicular to the fixing plate, and a sliding frame is slidably connected inside the sliding groove, and the bottom ring slides along the inside of the sliding frame.

[0010] Furthermore, a certain interval is provided between the inner ring and the outer ring of the grinding disc.

[0011] Furthermore, flat head screws are rotatably mounted on both sides of the inner ring of the outer ring through bearings, and screw holes are opened at positions corresponding to the flat head screws on the outside of the mounting hole.

[0012] Furthermore, the saw blade body and the grinding disc are both made of diamond material.

[0013] Beneficial effects of the utility model: The utility model is a dual-purpose cutting and grinding diamond saw blade, comprising a saw blade body; a mounting groove; a mounting hole; a locking assembly; a bottom ring; a horizontal plate; a slide groove; a slide frame; an outer ring; a fixing plate; a screw hole; a flat head screw; a grinding disc; a slot; a card slot;

[0014] 1. The utility model guides and limits the grinding disc by inserting the slot into the horizontal plate, thereby completing the connection with the locking assembly. The horizontal plate rotates into the slot, thereby preventing the grinding disc from falling out of the installation slot when in use.

[0015] 2. The utility model fixes the grinding disc by inserting a flat head screw into a screw hole. The screw hole has a certain depth. Therefore, the thickness of the protruding mounting groove of the grinding disc can be determined according to the insertion depth of the flat head screw, thereby facilitating switching between grinding and cutting states.

[0016] 3. Compared with the prior art, the utility model has a grinding disc installed inside the mounting groove of the saw blade body through a locking assembly, which facilitates the removal, replacement and installation of the grinding disc. The grinding disc is driven to move outward by the flat head screw of the locking assembly, and then the grinding disc can be protruded out of the mounting groove, thereby preventing the blade end of the saw blade body from being worn.
