[0002] With the development of society and the advancement of science and technology, milling cutters are rotating tools with one or more teeth used for milling processing. When working, each tooth cuts off the excess of the workpiece intermittently in turn. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. Therefore, milling cutters are tools with a relatively high loss rate on milling machines. Therefore, in order to reduce waste, double-head milling cutters are often used on milling machines.

[0003] The currently published patent: CN214023699U discloses an integral double-headed forming groove milling cutter for stainless steel processing. The cutting edge profile of the forming milling cutter is designed according to the workpiece profile, ensuring the integrity and consistency of the specific forming shape of the workpiece of difficult-to-process materials cut by the tool, as well as the dimensional accuracy and positional accuracy; the tool structure design with a rough and fine head integrated also improves the efficiency of forming cutting processing, increases the surface accuracy of workpiece processing, and extends the service life of the tool, while also effectively reducing the tool replacement cost and storage space.

[0004] Based on the above search, it was found that the above patent has the following problems when used: the integral double-headed forming slot milling cutter used for stainless steel processing ensures the integrity and consistency of the specific forming shape of the workpiece of difficult-to-process materials cut by the tool, as well as the dimensional accuracy and positional accuracy. However, the double-headed forming slot milling cutter is an integrated structure. When the tool rod is damaged, it needs to be replaced as a whole, and the blade cannot be used if it is still intact. The tool rod at one end cannot be replaced separately, and replacing the tool rod as a whole increases the economic loss of tool replacement. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a replaceable double-ended alloy tool, which can solve the problem that when the tool rod is damaged, it needs to be replaced as a whole, while the blade is still intact and cannot be used further, and the tool rod at one end cannot be replaced separately.

[0006] To achieve the above object, the utility model provides the following technical solution: a replaceable double-headed alloy tool, comprising a cylindrical tool handle, a positioning ball is fixedly connected to the top of the cylindrical tool handle, a first tool rod is slidably connected to the inside of the cylindrical tool handle, a second tool rod is slidably connected to the bottom of the first tool rod, and the second tool rod is slidably connected to the inside of the cylindrical tool handle;

[0007] Wherein, a clamping and fixing device is arranged inside the cylindrical tool handle.

[0008] Preferably, the clamping and fixing device comprises two arc-shaped clamping plates, both of which are slidably connected to the inside of the cylindrical tool handle, and both of which are in contact with the surfaces of the first tool rod and the second tool rod;

[0009] The inner thread of the cylindrical tool handle is connected with two hexagonal bolts, and the two hexagonal bolts are rotatably connected to the surface of the arc-shaped clamping plate on the same side.

[0029] See also Figure 1-5 The utility model provides a technical solution: a replaceable double-headed alloy tool, comprising a cylindrical tool handle 1, a positioning ball 2 is fixedly connected to the top of the cylindrical tool handle 1, a first tool rod 3 is slidably connected inside the cylindrical tool handle 1, a second tool rod 4 is slidably connected to the bottom of the first tool rod 3, and the second tool rod 4 is slidably connected inside the cylindrical tool handle 1;

[0030] The cylindrical tool handle 1 is internally slidably connected with two arc-shaped clamping plates 5, and the two arc-shaped clamping plates 5 are in contact with the surfaces of the first tool rod 3 and the second tool rod 4;

[0031] The inner thread of the cylindrical tool handle 1 is connected with two hexagonal bolts 6, and the two hexagonal bolts 6 are both rotatably connected to the surface of the arc-shaped clamping plate 5 on the same side;

[0032] There are two circular holes 12 on the surface of the cylindrical tool handle 1, and two hexagonal bolts 6 are slidably connected inside the circular holes 12 on the same side;

[0033] When the replaceable double-headed alloy tool is in use, when one of the first tool rod 3 and the second tool rod 4 is damaged, the staff first rotates the hexagonal bolt 6 with a hexagonal wrench. The hexagonal bolt 6 rotates and drives the two arc clamps 5 to move away from the surfaces of the first tool rod 3 and the second tool rod 4 through the threaded action between the hexagonal bolt 6 and the cylindrical tool handle 1, thereby releasing the fixing effect of the two arc clamps 5 on the first tool rod 3 and the second tool rod 4. The staff slides the first tool rod 3 and the second tool rod 4 downward to separate from the inside of the cylindrical tool handle 1 to complete the disassembly. At this time, the staff can make the first tool rod 3 and the second tool rod 4 separate from each other's surfaces, and the staff can replace the first tool rod 3 and the second tool rod 4 separately. When the tool rod is damaged, it is no longer necessary to replace it as a whole. The staff can replace the damaged tool rod at one end separately, thereby reducing the economic loss of tool replacement.

[0034] The first blade rod 3 has a fixed slot 7 on its surface, and the second blade rod 4 has a fixed block 8 on its surface, which is slidably connected to the fixed slot 7.

[0035] When the staff is installing the first knife bar 3 and the second knife bar 4, the staff slides the second knife bar 4 and drives the fixed block 8 to slide into the fixed slot 7, thereby ensuring the stability of the connection between the first knife bar 3 and the second knife bar 4 and avoiding the first knife bar 3 and the second knife bar 4 from sliding up and down relative to each other.

[0036] The surfaces of the first blade rod 3 and the second blade rod 4 are each provided with two blade grooves 9, the interiors of the four blade grooves 9 are all slidably connected with alloy blades 10, and the interiors of the four alloy blades 10 are all rotatably sleeved with screws 11;

[0037] A screw hole 13 is formed on the inner wall of the blade groove 9 , and the screw 11 is threadedly connected inside the screw hole 13 .

[0038] When the alloy blade 10 is damaged, the staff can release the fixing effect of the alloy blade 10 by rotating the screw 11 and disengaging it from the inside of the screw hole 13. At this time, the staff can complete the disassembly by sliding the alloy blade 10 and disengaging it from the surface of the screw 11. The staff can take out a new alloy blade 10 and put it on the surface of the screw 11. The alloy blade 10 is fixedly installed in the inside of the blade groove 9 by the screw 11 to complete the installation. The alloy blade 10 is fixed by the screw 11, which improves the convenience of disassembly and installation of the alloy blade 10.

[0039] Working principle: for the replaceable double-headed alloy tool, when one of the first tool rod 3 and the second tool rod 4 is damaged, the staff first rotates the hexagonal bolt 6 with the hexagonal wrench. The hexagonal bolt 6 rotates and drives the two arc clamps 5 to move away from the surfaces of the first tool rod 3 and the second tool rod 4 through the threaded action between the hexagonal bolt 6 and the cylindrical tool handle 1, thereby releasing the fixing effect of the two arc clamps 5 on the first tool rod 3 and the second tool rod 4. The staff slides the first tool rod 3 and the second tool rod 4 downward to separate from the interior of the cylindrical tool handle 1 to complete the disassembly. At this time, the staff can make the first tool rod 3 and the second tool rod 4 separate from each other's surfaces, and the staff can replace the first tool rod 3 and the second tool rod 4 separately. The staff slides the second tool rod 4 and drives the fixed card block 8 to slide into the interior of the fixed card slot 7 to ensure the stability of the connection between the first tool rod 3 and the second tool rod 4. The staff rotates the screw 11 and separates it from the interior of the screw hole 13 to release the fixing effect on the alloy blade 10. At this time, the staff slides the alloy blade 10 and separates it from the surface of the screw 11 to complete the disassembly.

[0040] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
