Technical Field
[0001] The present application relates to the field of alloy blade clamping equipment, and in particular to a blade fixing device for producing hard alloy blades. Background Art
[0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc., especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500°C, and still have a high hardness at 1000°C. Cemented carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drill bits, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel. It can also be used to cut difficult-to-process materials such as heat-resistant steel, stainless steel, high manganese steel, tool steel, etc.
[0003] There are many types of alloy cutting tools. Most of the existing alloy cutting tool fixing devices are used to clamp cutting tools with sheet structures. Compared with cutting tools with columnar structures, the clamping method is single and the angle of the clamp cannot be adjusted, which is not conducive to actual production. Utility Model Content

[0016] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.
[0017] The present application embodiment discloses a tool fixing device for producing hard alloy tools. Figure 1 and Figure 2 The device includes a base plate 1, a fixed block 11 fixed on the base plate 1, an adjusting block 12 for adjusting an angle hinged on the fixed block 11, an adjusting mechanism 2 for controlling the angle of the adjusting block 12 arranged on the base plate 1, and a clamp 3 rotatably connected to the adjusting block 12, wherein the adjusting block 12 is provided with a plurality of screw holes, the clamp 3 includes a positioning ring 31 and a clamping petal 32 fixedly connected to the positioning ring 31, the positioning ring 31 is provided with fixing holes having the same number as the screw holes, and the clamp 3 and the adjusting block 12 are fixed by bolts.
[0018] Please refer to Figure 1 The outer surface of the clamping petal 32 is provided with a thread, and the outer thread of the clamping petal 32 is connected with a clamping ring 33; the thickness of the clamping petal 32 gradually increases from the inside to the outside.
[0019] There are at least two clamping petals 32 for clamping a cylindrical tool. Before installing the clamp 3 on the adjustment block 12, the clamping ring 33 can be sleeved on the adjustment block 12, and then the clamp 3 can be bolted to the adjustment block 12. When the tool is clamped between the clamping petals 32, the clamping ring 33 can be rotated to clamp the tool by using the gradually increasing thickness of the clamping petals 32. When the clamp 3 needs to be adjusted circumferentially, the clamp 3 can be removed and readjusted to the required angle, and then re-fixed to the adjustment block 12, so as to adjust the axial angle of the tool.
[0020] Please refer to Figure 2 The adjustment mechanism 2 includes a motor 21 fixedly arranged on the bottom plate 1, a screw rod 22 rotatably connected to the bottom plate 1 and coaxially fixed to the output shaft of the motor 21, a moving block 23 threadedly connected to the screw rod 22, and a support rod 24 arranged on the moving block 23, one end of the support rod 24 is hinged to the lower part of the adjustment block 12, and the other end of the support rod 24 is hinged to the moving block 23. Further, a rectangular groove 13 is opened on the bottom plate 1, and the screw rod 22 and the moving block 23 are both arranged in the rectangular groove 13.
[0021] The rotation of the motor 21 drives the screw rod 22 to rotate, and the moving block 23 can be controlled to move along the screw rod 22. The inner wall of the rectangular groove 13 can form a sliding abutment with the moving block 23 to prevent the moving block 23 from rotating along the screw rod 22. When the support rod 24 and the screw rod 22 are in a vertical state, the free end of the adjusting block 12 is tilted upward. When the moving block 23 is away from the vertical foot of the support rod 24 and the screw rod 22, the adjusting block 12 can be controlled to be horizontal or the free end of the adjusting block 12 can be controlled to deflect downward, thereby realizing the angle adjustment of the adjusting block 12. The clamp 3 is set on the adjusting block, so that the clamp 3 and the clamped tool can realize radial angle adjustment.
