DETAILED DESCRIPTION

[0019] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of the utility model protection.

[0020] Please refer to Figs. 1-3 The utility model provides a technical scheme:

[0021] In the technical scheme, a tungsten steel blade convenient to disassemble comprises a rod body 1 and a cutting block 2, a placing groove 3 is formed in the upper wall of the rod body 1, the cutting block 2 is inserted into the placing groove 3, a locking bolt 4 is inserted and installed above the cutting block 2, and the cutting block 2 is fixedly installed on the rod body 1 through the locking bolt 4.

[0022] A through groove 5 is formed in the inner wall of the placing groove 3, a sliding rod 6 is slidingly installed in the through groove 5, a top plate 7 is installed on the upper wall of the sliding rod 6, the top plate 7 can be attached to the lower wall of the cutting block 2, and a connecting plate 8 is installed through the through groove 5 and the lower wall of the rod body 1.

[0023] In the technical scheme, when the device is used for cutting workpieces, the cutting block will be in contact with the workpieces, so that the workpieces are cut, and therefore the cutting block 2 will inevitably be worn and damaged, so the cutting block 2 needs to be replaced.

[0024] However, since the cutting block 2 is installed in the placing groove 3, the placing groove 3 can improve the stability of the installation of the cutting block 2, so that the cutting block 2 is relatively cumbersome to remove.

[0025] Therefore, the device is provided with the through groove 5 and the sliding rod 6 in the placing groove 3, so that the sliding rod 6 can be slid upward, and the top plate 7 can push the cutting block 2 out of the placing groove 3.

[0026] In some technical schemes, a through hole 9 is formed in the middle of the upper wall of the cutting block 2, the locking bolt 4 is inserted and installed in the through hole 9, a threaded hole 10 is formed in the middle of the placing groove 3, the locking bolt 4 is screwed and installed in the threaded hole 10, and an internal hexagonal hole 11 is formed in the upper wall of the locking bolt 4.

[0027] In the technical scheme, the cutting block 2 is fixedly installed in the placing groove 3 through the cooperation of the locking bolt 4 and the threaded hole 10.

[0028] In some technical solutions, the lower wall of the rod 1 is provided with a first positioning groove 12, and the positioning block on the external tool holder can be inserted into the first positioning groove 12. The upper wall of the rod 1 is provided with a second positioning groove 13, and the screw on the external tool holder can be screwed into the second positioning groove 13.

[0029] In this technical solution, the connection between the rod body 1 and the tool mounting bracket can be made more stable through the first positioning groove 12 and the second positioning groove 13, so as to avoid the rod body 1 from shaking during processing and affecting the processing accuracy.

[0030] In some technical solutions, a groove 14 is provided at the upper end of the through hole 9, and an annular sealing gasket 15 is installed on the inner wall of the groove 14. The annular sealing gasket 15 can fit against the lower wall of the locking bolt 4.

[0031] In this technical solution, the annular sealing gasket 15 can seal the gap between the through hole 9 and the locking bolt 4, preventing the cutting fluid from entering the through hole 9 and the threaded hole 10 during use, and preventing the locking bolt 4 from rusting, which would affect the subsequent disassembly of the cutting block 2.

[0032] In some technical solutions, there are two through slots 5, which are respectively set on the left and right sides of the through hole 9. A sliding rod 6 is inserted into each of the two through slots 5. A connecting plate 8 is installed on the lower wall of the two sliding rods 6. One end of a spring 16 is installed on the upper wall of the connecting plate 8, and the other end of the spring 16 is attached to the lower wall of the rod body 1.

[0033] In this technical solution, the spring 16 ensures that the top block 7 remains within the groove 14 during normal use, thus preventing any impact on the cutting block 2.

[0034] In some technical solutions, a positioning block 17 is installed on the upper wall of the connecting plate 8, and a spring 16 is sleeved on the outside of the positioning block 17.

[0035] In this technical solution, the positioning block 17 can prevent the spring 16 from bending or deflecting.

[0036] Working principle: The rod 1 is mounted on the tool holder of an external machine tool, and then the workpiece is cut by the cutting block 2;

[0037] When the cutting block 2 is excessively worn and needs to be replaced, the locking bolt 4 can be unscrewed from the threaded hole 10, and then the connecting plate 8 located below the rod 1 can be pushed upward, causing the slide rod 6 and the top plate 7 to move upward, pushing the cutting block 2 out of the placement groove 3, and replacing the cutting block 2.
