Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a polycrystalline cutting blade with a positioning structure. Background Art

[0002] Polycrystalline cutting tools have the characteristics of high hardness, high compressive strength, good thermal conductivity and wear resistance, and can achieve high processing accuracy and processing efficiency in high-speed cutting. The above characteristics of polycrystalline cutting tools are determined by the state of diamond crystals. In diamond crystals, the four valence electrons of carbon atoms form bonds in a tetrahedral structure, and each carbon atom forms a covalent bond with four adjacent atoms to form a diamond structure. The binding force and directionality of this structure are very strong, which makes diamond extremely hard. Since the structure of polycrystalline diamond (PCD) is a fine-grained diamond sintered body with different orientations, although a binder is added, its hardness and wear resistance are still lower than those of single crystal diamond. However, since the PCD sintered body is isotropic, it is not easy to crack along a single cleavage plane.

[0003] However, when the existing polycrystalline blade is used, the tool rod is usually passed through the through hole opened on the surface of the polycrystalline blade to fix the tool rod on the polycrystalline blade. When the polycrystalline blade processes the workpiece, the polycrystalline blade will wear and needs to be replaced. However, the operation steps are cumbersome when the tool rod is separated from the polycrystalline blade, and the tool rod is difficult to remove from the polycrystalline blade, which is inconvenient to remove and replace the polycrystalline blade, which has a certain impact on the processing efficiency of the workpiece. Therefore, a polycrystalline blade with a positioning structure is provided. Utility Model Content

[0004] The main purpose of the utility model is to provide a polycrystal blade with a positioning structure. The utility model solves the problem of poor stability of the connection between the tool rod and the polycrystal blade body when the existing polycrystal blade is in use by arranging a fixing block A, a fixing block B, a spring A, a spring B, a threaded sleeve, a limit block A, a limit block B, a clamping block A, a clamping block B, a connecting block A, a connecting block B, a spring D and a spring C.

[0005] The technical solution adopted by the utility model to solve its technical problems is a polycrystal blade with a positioning structure, comprising a polycrystal blade body, a positioning component for fixing a tool rod is arranged on the outside of the polycrystal blade body, the positioning component comprises a fixing block A and a fixing block B installed on the outside of the polycrystal blade body, a spring A for resetting the clamping block A is welded on one side of the fixing block A, a limit block A for fixing the tool rod is integrally formed on the outside of the clamping block A, a spring B for resetting the clamping block B is welded on the inside of the fixing block B, a limit block B for fixing the tool rod is integrally formed on the outside of the clamping block B, a threaded sleeve is externally threadedly connected to the limit block A and the limit block B, a threaded groove for moving the threaded sleeve is provided on the surface of the limit block A and the limit block B, a spring C for resetting the connecting block A is welded on one side of the polycrystal blade body, a spring D for resetting the connecting block B is welded on the outside of the polycrystal blade body, and a through hole for moving the tool rod is provided on the surface of the polycrystal blade body.

[0006] By adopting the above technical solution, when the tool rod is connected to the polycrystalline blade body, first rotate the threaded sleeve outside the limit block A and the limit block B to remove the threaded sleeve from the limit block A and the limit block B, then the spring A in the fixed block A drives the limit block A to move, and the spring B in the fixed block B drives the limit block B to move, so that the clamping block A and the clamping block B are separated, and then pull the connecting block A and the connecting block B on the polycrystalline blade body, and compress the spring C on one side of the connecting block A, and compress the spring D outside the connecting block B, and then put the tool rod into the through hole opened on the surface of the polycrystalline blade body, and the spring C drives the connecting block A and the surface of the tool rod. Contact, spring D drives connecting block B to contact with the tool rod, and then pulls clamp block A and clamp block B on the polycrystalline blade body to move, and then clamp block A moves and the inner side of clamp block B contacts the surface of the tool rod, and then the threaded sleeve passes through the outside of the tool rod, and then presses the limit block A outside clamp block A, presses the limit block B outside clamp block B, and then places the threaded sleeve outside clamp block A and clamp block B, and the threaded sleeve moves through the threaded grooves opened on the surfaces of clamp block A and clamp block B, so that clamp block A and clamp block B are in close contact with the surface of the tool rod, thereby facilitating the close connection between the tool rod and the polycrystalline blade body and improving the stability of the connection between the tool rod and the polycrystalline blade body.

[0007] Specifically, support blocks are welded on the outer sides of the clamping block A and the clamping block B, and support rods for enabling the support blocks to slide are welded on the inner sides of the fixed block A and the fixed block B.

[0008] By adopting the above technical solution, when clamp block A and clamp block B move outside the polycrystalline blade body, the support blocks outside clamp block A and clamp block B slide outside the support rod between fixed block A and fixed block B respectively, thereby improving the stability of the movement of clamp block A and clamp block B.

[0009] Specifically, rubber pads are bonded to the inner sides of the limit blocks A and B to ensure stable clamping of the knife bar.

[0010] By adopting the above technical solution, when the limit blocks A and B come into contact with the tool rod, the rubber pads in the limit blocks A and B increase the friction force on the surface of the tool rod, thereby improving the stability of clamping the tool rod.

[0011] Specifically, the inner sides of the connecting block A and the connecting block B are bonded with convex pads for increasing the friction force on the knife rod.

[0012] By adopting the above technical solution, when the connecting block A and the connecting block B clamp the tool rod, the convex pads on the inner sides of the connecting block A and the connecting block B increase the friction force on the surface of the tool rod.

When the tool rod is connected to the polycrystalline blade body, the threaded sleeve outside the limit block A and the limit block B is first rotated to remove the threaded sleeve from the limit block A and the limit block B. Then the spring A inside the fixed block A drives the limit block A to move, and the spring B inside the fixed block B drives the limit block B to move, so that the clamping block A and the clamping block B are separated. Then the connecting block A and the connecting block B on the polycrystalline blade body are pulled, and the spring C on one side of the connecting block A is compressed, and the spring D outside the connecting block B is compressed. Then the tool rod is placed in the through hole opened on the surface of the polycrystalline blade body, and the spring C drives the connecting block A to move.
