[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0025] Example

[0026] Please refer to Figure 1-4 As shown, the utility model provides a technical solution: a tool holder for a CNC machine tool;

[0027] A circular ring 5 is fixedly installed on the inner end of the tool holder 1, a clamping member 6 is fixedly installed on the lower end of the circular ring 5, a fastening slope 7 is integrally installed on the lower end of the clamping member 6, a clamping block 8 is fixedly installed on the inner surface of the fastening slope 7, and four groups of the clamping blocks 8 are provided, with two blocks provided vertically in each group. A mounting seat 4 is fixedly installed on the upper end of the tool holder 1. A boss 9 is integrally installed on the inner end of the tool holder 1, and the boss 9 is provided on the lower side of the protrusion 10. The fastener 3 is threadedly connected to the inner end of the tool holder 1, and a protrusion 10 is integrally installed on the outer surface of the fastener 3. The inner surface of the fastener 3 is tightly fitted on the outer surface of the fastening slope 7, which is convenient for quick installation, disassembly and replacement of the tool, shortening the working time and improving the working efficiency.

[0028] The outer end of the tool body 2 is provided with a snap-fit ​​groove 11, and the inner end of the snap-fit ​​groove 11 is snap-fitted with a snap-fit ​​block 8, so that the tool body 2 is closely attached to the inner surface of the clamping member 6, and the tool body 2 passes through the inside of the fastener 3 and the ring 5. The snap-fit ​​block 8 is fixedly installed on the inner surface of the clamping member 6, the structure is stable and coherent, and the operation is simple and convenient.

[0029] Specific working principle:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the CNC machine tool tool holder is used, the mounting seat 4 is installed with the CNC machine tool to fix the mounting tool holder 1. When there is no external force pushing inward, the clamping piece 6 and the fastening slope 7 are slightly opened outward. The metal product is sturdy and durable and has a certain elastic deformation. The fastener 3 is threaded downward and rotated at the inner end of the mounting tool holder 1. The clamping piece 6 and the fastening slope 7 are opened outward, and the tool body 2 can be inserted into the inside of the fastener 3, and then pushed upward to the inside of the mounting tool holder 1. The tool body 2 passes through the inside of the ring 5 until the top of the tool body 2 contacts the top of the slot inside the mounting tool holder 1. At this time, the position of the engaging groove 11 corresponds to the engaging block 8. The fastener 3 is rotated upward to lock it. When the fastener 3 is rotated upward, the inner surface squeezes the fastening slope 7 inward to make the fastening slope 7 and the clamping member 6 are tightly fitted on the outer surface of the tool body 2. When the clamping member 6 and the fastening slope 7 lock and fix the tool body 2, the locking block 8 is locked into the inside of the locking groove 11 to prevent the tool body 2 from loosening and falling off, thereby improving the stability of the installation of the tool body 2. When the tool body 2 needs to be replaced, when the fastener 3 is rotated downward, the activity space of the fastening slope 7 becomes larger, the fastening slope 7 and the clamping member 6 are opened outward, the locking block 8 is moved out from the inner end of the locking groove 11, the protrusion 10 contacts the boss 9, and the fastener 3 plays a limiting role to prevent the fastener 3 from falling off, which is convenient for the next installation. Then the tool body 2 can be pulled out vertically downward for replacement. The above completes a series of operations of the CNC machine tool tool holder. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
