[0029] The present invention will be further described below in conjunction with the embodiments.

[0030] pass Figures 1-9 It can be seen that the detachable CNC planer tool assembly for processing the Roots blower impeller includes a tool rod 1 and a tool head 2. The tool rod 1 and the tool head 2 are detachably fixed. When the blade has been used for a long time or is bumped, it is only necessary to replace the new tool head 2. More importantly, since the tool rod 1 has not been disassembled, there is no need to recalibrate the tool after replacing the new tool head 2. The entire operation process saves time and effort, increases work efficiency, and ensures the normal processing progress of the workpiece. Moreover, different types of tool heads can be quickly replaced according to the processing requirements of the workpiece material. The operation is convenient and fast, and the application range is wide. For example, when it is necessary to process a stainless steel workpiece, a stainless steel blade 2 is used instead. When it is necessary to process a cast iron workpiece, a cast iron blade 2 is used instead.

[0031] The tool rod 1 includes a tool rod connecting section 101 and a tool rod fixing section 102. The tool rod connecting section 101 is located at the upper section of the tool rod 1, and the tool rod fixing section 102 is located at the lower section of the tool rod 1. The cutter head 2 includes a cutter head cutting section 201 and a cutter head connecting section 202. The cutter head cutting section 201 is located at the upper section of the cutter head 2, and the cutter head connecting section 202 is located at the lower section of the cutter head 2.

[0032] The tool rod connecting section 101 is a step structure, and the tool rod connecting section 101 includes a front end positioning section 10101 of the tool rod connecting section and a rear end fixed support section 10102 of the tool rod connecting section. The upper end of the front end positioning section 10101 of the tool rod connecting section is provided with a cutter head positioning groove 3, which is used to position and install the cutter head 2. The adjacent longitudinal end of the cutter head positioning groove 3 on the rear end fixed support section 10102 of the tool rod connecting section is provided with a slot hole 4, which is used to realize quick disassembly and assembly between the cutter head 2 and the tool rod 1, as well as locking and fixing.

[0033] The cutter head 2 includes a cutter head cutting section 201 and a cutter head connecting section 202. The cutter head cutting section 201 is located at the upper section of the cutter head 2, and the cutter head connecting section 202 is located at the lower section of the cutter head 2. The shape of the cutter head connecting section 202 is symmetrical to the shape of the cutter head positioning groove 3. The cutter head connecting section 202 can fit tightly with the inside of the cutter head positioning groove 3 to realize the positioning and installation of the cutter head 2.

[0034] A blade 7 is provided at the connecting position between the upper end portion and the front end portion of the cutting segment 201 of the cutter head, and the planing operation on the workpiece is realized by the blade 7. A chip breaker groove 8 is provided on the front end portion of the cutting segment 201 of the cutter head, adjacent to the blade 7. During the planing process, chips will continuously detach from the processing surface and be generated. If they are not cleaned in time, the chips will be stuck in the processing part, affecting the processing quality and even damaging the workpiece and the tool. The function of the chip breaker groove 8 is to allow the generated chips to be discharged along the groove in time to ensure the smooth progress of the planing process.

[0035] A through hole 9 is provided in the middle position of the cutter head 2, and the through hole 9 runs through the middle position of the cutter head 2 from front to back. During the installation process of the cutter head 2, first, the cutter head connecting section 202 on the cutter head 2 is completely fitted into the inside of the cutter head positioning groove 3, and then, the screw 10 is passed through the through hole 9 and threadedly locked with the slot hole 4 on the rear end fixed support section 10102 of the tool rod connecting section. At this time, the cutter head 2 is respectively in a fitted and locked state with the cutter head positioning groove 3 and the rear end fixed support section 10102 of the tool rod connecting section, thereby realizing all-round locking and fixation between the cutter head 2 and the tool rod 1, thereby ensuring the consistency of the position of the cutter head 2 after each replacement of the cutter head 2, avoiding repeated tool calibration, and saving operation time.

[0036] The cutter head positioning groove 3 is in a V-shaped groove shape, and the bottom end of the V-shaped cutter head positioning groove 3 is smoothly inclined downward from the inside to the outside to form a drainage groove 6.

[0037] First, by setting the shape of the cutter head positioning groove 3 to a V shape, since the inverted triangle structure of the V shape has the characteristics of contraction and extrusion, the support strength and positioning stability of the cutter head positioning groove 3 to the cutter head 2 can be increased, thereby avoiding the cutter head 2 from shaking when being installed. In addition, by setting a drain groove 6 that smoothly tilts downward from the inside to the outside at the bottom end of the cutter head positioning groove 3, when dust and foreign matter fall into the bottom end of the cutter head positioning groove 3, the dust and foreign matter can be smoothly discharged through the action of gravity under the tilt of the drain groove 6, or with the help of a cleaning tool, the dust and foreign matter in the cutter head positioning groove 3 can be easily cleaned under the action of gravity, further ensuring the consistency of the position of the cutter head 2 after each replacement of the cutter head 2, thereby achieving the accuracy of processing the workpiece.

[0038] The drain groove 6 at the bottom of the cutter head positioning groove 3 is a smooth arc transition, which can increase the contact radius of the drain groove 6, effectively prevent dust and foreign matter from accumulating in the drain groove 6, and make it more convenient to clean the cutter head positioning groove 3.

[0039] The front end port of the through hole 9 is a countersunk hole, and the screw 10 is a countersunk screw, which can ensure that after the screw 10 is locked, the top position of the screw 10 will not exceed the front end face of the cutter head 2, thereby avoiding the top position of the screw 10 exceeding the front end face of the cutter head 2, causing the screw 10 to form processing interference when processing the workpiece.

[0040] The thickness of the tool rod connecting section 101 is smaller than that of the tool rod fixing section 102. The tool rod connecting section 101 is located in the middle position of the upper end of the tool rod fixing section 102. The two sides of the bottom end of the tool rod connecting section 101 and the connection position of the tool rod fixing section 102 are respectively provided with chamfers 5. The chamfers 5 are inner chamfers, and their main function is to increase the connection strength between the tool rod connecting section 101 and the tool rod fixing section 102, forming a high-strength support, and avoiding the tool rod connecting section 101 from being damaged or broken when used for a long time.

[0041] However, the above description is merely a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
