Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figure 1-4 As shown, the crankshaft machining tool holder shown in the figure includes a base 1 and a mounting mechanism arranged inside the base 1, and the mounting mechanism includes a working component and a mounting component;

[0025] The working assembly includes a connecting block 2 and a knife seat 3. The top of the base 1 is fixedly connected to the connecting block 2, and the top of the connecting block 2 is fixedly connected to the knife seat 3.

[0026] The mounting assembly includes a fixed block 4, a spring 5, an extrusion block 6, a first clamping block 7, a first fixed groove block 8, a groove opening 9 and a first clamping slot 10. The inner wall of the tool holder 3 is fixedly connected with the fixed block 4, one end of the fixed block 4 is provided with a spring 5, the end of the spring 5 away from the fixed block 4 is provided with an extrusion block 6, the bottom end of the extrusion block 6 is fixedly connected with the first clamping block 7, the outside of the tool holder 3 is provided with a first fixed groove block 8, the interior of the first fixed groove block 8 is provided with a groove opening 9, and the interior of the first fixed groove block 8 is provided with a first clamping slot 10.

[0027] Among them, such as Figure 3 As shown, there are two groups of first clamping blocks 7, and the positional relationship of the two groups of first clamping blocks 7 is symmetrical about the midpoint of the fixed block 4. This is beneficial for more stably clamping the first fixed groove block 8 inside the knife seat 3 through the arrangement of the two groups of first clamping blocks 7, making the clamping and fixing operation of the first fixed groove block 8 more stable.

[0028] Among them, such as Figure 3As shown, the spring 5 forms a compression structure through the extrusion block 6 and the fixed block 4, which is conducive to pressing the extrusion blocks 6 at both ends. At the same time, the spring 5 is compressed under the action of the fixed block 4, which makes it easy to move the first clamping block 7 into the first fixed slot block 8.

[0029] Among them, such as Figure 3 As shown, the first clamping block 7 is tightly fitted with the surface of the first clamping slot 10 , which is beneficial for more stability when the first clamping block 7 is clamped with the first clamping slot 10 , thereby achieving stable fixing operation of the first fixing slot block 8 .

[0030] Example 2

[0031] like Figure 1 、 Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, one end of the first fixed slot block 8 is fixedly connected to the second fixed slot block 11, the outer wall of the second fixed slot block 11 is rotatably connected to the clamping plate 12, the interior of the second fixed slot block 11 is provided with a second clamping slot 13, the outside of the second fixed slot block 11 is provided with a second clamping block 14, the outer wall of the second clamping block 14 is fixedly connected to a limiting block 15, the interior of the limiting block 15 is provided with a bolt 16, and one end of the second clamping block 14 is fixedly connected to a tool 17.

[0032] Among them, such as Figure 4 As shown, the tool 17 forms a positioning structure with the second clamping block 14 and the second clamping groove 13 and the second fixed groove block 11, which is conducive to positioning the tool 17 on the second fixed groove block 11 through the engagement of the second clamping block 14 and the second clamping groove 13, thereby facilitating the installation of the tool 17.

[0033] Among them, such as Figure 4 As shown, the second clamping block 14 forms a fixed structure with the second fixed slot block 11 through the clamping plate 12, the limit block 15 and the bolt 16, which is conducive to rotating the clamping plate 12 so that it is clamped in the limit block 15, and then by tightening the bolt 16, the clamping plate 12 is fixed on the limit block 15 and the second clamping block 14, so that the head of the tool 17 is fixed on the second fixed slot block 11, which is convenient for selecting a suitable tool head for replacement according to the crankshaft processing conditions, without having to replace the entire blade body, reducing the replacement of accessories.

[0034] When in use: First, press the extrusion blocks 6 at both ends, thereby driving the spring 5 to compress. At this time, the two groups of first clamping blocks 7 move with the extrusion blocks 6, and push the first fixed slot block 8 into the groove inside the tool holder 3. At this time, the first clamping blocks 7 at both ends pass through the groove opening 9 to reach the first clamping groove 10, and then release the extrusion block 6. The spring 5 pops out, and the first clamping block 7 moves with the extrusion block 6. At this time, the first clamping block 7 is clamped into the first clamping groove 10 for clamping operation, thereby fixing the first fixed slot block 8 on the tool holder 3, thereby facilitating the installation and disassembly of the first fixed slot block 8 and facilitating the installation of the integral components of the tool 17 on the tool holder 3.

[0035] Finally, by engaging the second clamping block 14 with the second clamping slot 13, the tool 17 is positioned on the second fixed slot block 11, and then the clamping plate 12 is rotated to make it clamped in the limit block 15, and then the bolt 16 is tightened to fix the clamping plate 12 on the limit block 15 and the second clamping block 14, so that the head of the tool 17 is fixed on the second fixed slot block 11, which is convenient for selecting a suitable tool head for replacement according to the crankshaft processing conditions, and there is no need to replace the entire blade body. Only the required tool head needs to be disassembled and replaced. Even when the tool head is worn, the replacement parts are relatively reduced, thereby reducing the replacement cost.
