Description

Technical Field

[0001] The utility model relates to the technical field of alloy tool bits, in particular to a flat alloy tool bit. Background Technique

[0002] Alloy tool bits are necessary components of existing hardware tools. The existing alloy tool bits for drill bits are basically flat-shaped. They are fixed at the end of the drill rod by welding to form a drill bit with left and right cutting edges. In this way, drilling or cutting operations are achieved by driving the rotation of the drill bit with an electric drill.

[0003] Most of the heads of the existing flat alloy tool bits are beveled. Such alloy tool bits can improve their cutting performance. During the cutting process, the alloy tool bits are severely worn, resulting in a reduction in cutting ability. Since most of the existing alloy tool bits are integrally formed, during the long-term cutting process, the alloy tool bits need to be replaced multiple times, thus increasing the usage cost.

A limiting block for limiting the alloy blade is connected through the limiting threaded hole. The bottom surface of the end of the limiting block away from the limiting threaded hole is in contact with the top surface of the alloy blade.

[0006] Preferably, a fixing threaded hole is opened on the surface of the installation position. A fixing hole is opened on the surface of the alloy blade at a position opposite to the fixing threaded hole. The alloy blade is fixedly connected by a fastener passing through the fixing hole and the fixing threaded hole in a threaded manner.

[0007] Preferably, a connection hole is opened on the top surface of the limiting block. A pressing block is fixedly connected to the bottom surface of the end of the limiting block away from the connection hole. And the pressing block is movably connected to the top surface of the alloy blade at the position of the fixing hole.

[0016] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance.

[0018] Such as Figure 1-2It is a structural schematic diagram of a straight alloy cutter head in a preferred embodiment of the utility model. In this embodiment, a straight alloy cutter head comprises a cutter body 1, a mounting position 4 is provided on the front end surface of the cutter body 1, an alloy blade 2 is installed in the mounting position 4, and a limiting threaded hole 7 is provided on the surface of the cutter body 1 directly behind the mounting position 4, a limiting block 3 for limiting the alloy blade 2 is connected through the limiting threaded hole 7, and the bottom surface of the limiting block 3 away from the limiting threaded hole 7 is in contact with the top surface of the alloy blade 2, thereby preventing the alloy blade 2 from falling off during the processing of the workpiece; combined with the design of the above structure, the alloy cutter head has the function of disassembly, assembly and replacement, thereby reducing the cost of use and improving practicality.

[0019] In this embodiment, a fixing threaded hole 5 is provided on the surface of the mounting position 4, a fixing hole 6 is provided on the surface of the alloy blade 2 at a position relative to the fixing threaded hole 5, and the alloy blade 2 is threadedly fixedly connected to the fixing threaded hole 5 by a fastener 9 passing through the fixing hole 6, thereby fixing the alloy blade 2 to the mounting position 4 by the fastener 9.

[0020] In this embodiment, a connecting hole 8 is provided on the top surface of the limit block 3, and a clamping block 10 is fixedly connected to the bottom surface of the limit block 3 away from the connecting hole 8, and the clamping block 10 is movably connected to the top surface of the alloy blade 2 at the fixing hole 6. The clamping block 10 prevents the fastener 9 used to fix the alloy blade 2 from loosening and detaching during the chip cutting process, which may cause the alloy blade 2 to fail to work.

[0021] In this embodiment, the limit block 3 is threadedly fixedly connected to the limit threaded hole 7 by a fastener 9 passing through the connecting hole 8. This structural design realizes the installation and fixation of the limit block 3 and also facilitates the subsequent disassembly and assembly of the alloy blade 2.

[0022] Work away

[0023] During specific use, during installation, align the alloy blade 2 and place it in the installation position 4, fix the alloy blade 2 by the fastener 9, and then tighten the limit block 3 by the fastener 9. At this time, the clamping block 10 of the limit block 3 needs to be adjusted to the fixing hole 6, and tightened by the fastener 9, so that the clamping block 10 contacts the fastener 9 in the fixing hole 6 to achieve a state of interference, thereby completing the installation and fixation; similarly, during disassembly, the fastener 9 used to fix the limit block 3 is removed, so that the limit block 3 is in a loose and rotatable state, and then the fastener 9 used to fix the alloy blade 2 is removed, thereby completing the disassembly of the alloy blade 2.
