[0022] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0023] like Figure 1-Figure 4 As shown, a tool assembly for a CNC slotting machine provided in this embodiment includes a tool handle 1, a tool head 2 is installed at the bottom end of the tool handle 1, a clamping assembly 3 is arranged between the tool handle 1 and the tool head 2, the clamping assembly 3 is composed of a connecting cavity 302, a connecting column 303, a locking hole 304, a locking rod 305, a transmission box 301, a knob 306, a main gear 307, a transmission gear 308 and a sub-gear 309, and a limit assembly 4 is arranged on the upper end of the clamping assembly 3, and the limit assembly 4 is composed of a limit cavity 404, a limit rod 403, a connecting rod 402 and a telescopic column 401.

[0024] The connecting cavity 302 is formed inside the bottom end of the handle 1, and the connecting column 303 is formed at the top end of the cutter head 2. The specifications of the connecting cavity 302 and the connecting column 303 match. The connecting cavity 302 and the connecting column 303 can be combined to achieve the initial connection of the handle 1 of the cutter head 2.

[0025] The locking hole 304 is formed on the connecting column 303, the locking hole 304 is a threaded hole, the locking rod 305 is a threaded rod, and a through cavity matching the specifications of the locking rod 305 is opened at a position corresponding to the locking hole 304 on one side wall of the handle 1. The locking rod 305 is combined with the locking hole 304 to achieve a stable connection between the cutter head 2 and the handle 1.

[0026] The main gear 307, the transmission gear 308 and the sub-gear 309 are all rotatably installed in the transmission box 301, and one end of the locking rod 305 is fixedly connected to the main gear 307 and the sub-gear 309. A knob 306 is led out from the main gear 307, and the knob 306 is set at the top of the transmission box 301. When disassembling and assembling the cutter head 2, it is only necessary to drive the main gear 307 to rotate through the knob 306, and the main gear 307 then drives the sub-gear 309 to rotate through the transmission gear 308, so that the main gear 307 and the sub-gear 309 can synchronously drive the three groups of locking rods 305 to rotate, and there is no need to disassemble and assemble the three groups of locking rods 305 in turn, which effectively improves the replacement efficiency of the cutter head 2.

[0027] The limiting cavity 404 is formed at the top of the knob 306 , the limiting rod 403 is plugged into the limiting cavity 404 , both the limiting rod 403 and the limiting cavity 404 are regular hexagonal structures, and the limiting rod 403 and the limiting cavity 404 can limit the knob 306 in combination.

[0028] A connecting rod 402 is fixed to the top of the limiting rod 403, and a telescopic column 401 is provided at the bottom of the other end of the connecting rod 402. The telescopic column 401 is rotatably installed on the top wall of the transmission box 301. On the one hand, the telescopic column 401 can drive the limiting rod 403 to separate from the limiting cavity 404 and fix the knob 306. On the other hand, the limiting rod 403 can be rotated to adjust to other directions, so that the staff can operate the knob 306 conveniently.

[0029] Two groups of positioning holes are provided on the fixed arm of the telescopic column 401 , and a group of positioning buttons are installed on the movable arm of the telescopic column 401 through a spring. The positioning buttons match the specifications of the positioning holes, and the positioning buttons and the positioning holes can be combined to fix the position of the limit rod 403 after the adjustment.

[0030] The working principle of the present device is as follows: when disassembling and assembling the cutter head 2, the limit rod 403 is separated from the limit cavity 404 by increasing the height of the telescopic column 401, and the fixation of the knob 306 is released. On the other hand, the limit rod 403 can be rotated to adjust to other directions, which is convenient for the staff to operate the knob 306. At this time, it is only necessary to drive the main gear 307 to rotate through the knob 306, and the main gear 307 then drives the sub-gear 309 to rotate through the transmission gear 308, so that the main gear 307 and the sub-gear 309 can synchronously drive the three sets of locking rods 305 to rotate, and there is no need to disassemble and assemble the three sets of locking rods 305 in turn, which effectively improves the replacement efficiency of the cutter head 2. After replacement, the limit rod 403 is adjusted to the top of the limit cavity 404, and the limit rod 403 is placed in the limit cavity 404 on the knob 306 by adjusting the telescopic column 401, so that the knob 306 can be limited to prevent it from rotating, thereby ensuring the stability of the cutter head 2 when in use. The combination of the two can effectively improve the use effect of the tool.
