[0043] In a specific embodiment, the slotting tool 32 includes a tool holder 321 and a tool body 322 mounted on the tool holder 321 , and the tool holder 321 is clamped to the clamping member 33 .

[0044] Specifically, the tool body 322 is embedded in the tool holder 321. The tool holder 321, as a supporting component of the slotting tool 32, can provide stable fixed support for the tool body 322, maintain the position stability and rigidity of the tool body 322 during the processing, thereby ensuring the precision and quality of the cutting process. In addition, the connection of the tool body 322 to the tool holder 321 can also enhance the stability of the slotting tool 32. Through the fixed connection between the tool body 322 and the tool holder 321, the vibration and deformation of the tool body 322 during the cutting process can be effectively reduced, thereby improving the processing stability and reliability of the cutting.

[0045] In a specific embodiment, a positioning protrusion 331 is provided on the fastener 33, and a positioning groove (not shown in the figure) corresponding to the positioning protrusion 331 is provided on the tool holder 321, so that the groover tool 32 can be accurately positioned on the fastener 33, thereby avoiding deviation caused by inaccurate alignment, improving the assembly accuracy and reliability of the groover tool 32, and reducing the debugging and calibration work when the groover tool 32 is replaced.

[0046] In a specific embodiment, the tool assembly mechanism 2 includes a mounting plate 21 movably connected to the frame 1 and a clamping tool rod 22 mounted on the mounting plate 21 , and the clamping tool rod 22 is used to clamp the planing tool 32 .

[0047] Specifically, the tool assembly mechanism 2 is a cutting mechanism in the slotting machine, the mounting plate 21 slides horizontally on the frame 1, the clamping tool rod 22 is arranged parallel to the mounting plate 21, and the slotting tool 32 is vertically assembled on the clamping tool rod 22, that is, the clamping tool rod 22 and the slotting tool 32 form a vertical distribution, so that in the actual planing process, the slotting tool 32 is subjected to the resistance of the sheet material and is transmitted axially to the clamping tool rod 22, thereby reducing the influence of the radial force on the clamping tool rod 22, so as to reduce the possibility of deformation and radial runout, so that the slotting tool 32 is less damaged and the planing accuracy is higher.

[0048] In a specific embodiment, the slotting tool 32 has a fixed end 3211 extending from one end close to the clamping tool rod 22 . The end of the clamping tool rod 22 has an open cavity 221 . The open cavity 221 has an elastic claw 221 for clamping the fixed end 3211 .

[0049] Specifically, the fixed end 3211 is arranged at one end of the tool seat 321 away from the tool body 322, and the fixed end 3211 is a tapered end. When the groove planing tool 32 is assembled on the clamping tool rod 22, the top of the tapered end extends into the clamping tool rod 22 and is clamped by the elastic claw 221, and the bottom of the tapered end abuts against the clamping tool rod 22, so that during the cutting process, the groove planing tool 32 is subjected to the resistance of the sheet material and is transmitted to the clamping tool rod 22, so that the groove planing tool 32 is less damaged and the planing accuracy is higher.

[0050] In a specific embodiment, the elastic claw 221 is connected to the pneumatic tension sleeve 222 , the knife seat 321 is connected to the pneumatic tension sleeve 222 , and a pneumatic part 223 is provided at one end of the clamping knife rod 22 away from the opening 221 , and the pneumatic part 223 is connected to the pneumatic tension sleeve 222 .

[0051] Specifically, when the pneumatic part 223 is activated, the air pressure inside the pneumatic part 223 will be transmitted to the pneumatic tension sleeve 222 to expand it, and the elastic claw 221 is connected to the pneumatic tension sleeve 222. When the pneumatic tension sleeve 222 expands, the elastic claw 221 will shrink and clamp on the top of the tapered end, thereby firmly fixing the tool holder 321; conversely, the elastic claw 221 opens to release the tapered end to achieve rapid tool change, thereby improving the automation rate of the equipment. This design can achieve rapid clamping and release of the slotting tool 32 through pneumatic control, thereby improving the efficiency of assembling and replacing the slotting tool 32; at the same time, since the clamping force of the pneumatic tension sleeve 222 can be adjusted, the clamping force of the slotting tool 32 can be flexibly controlled according to actual needs to adapt to different processing requirements and material properties.

[0052] The pneumatic part 223 adopts an existing publicly available pneumatic device, which will not be elaborated in detail here.

[0053] In a specific embodiment, a limiting protrusion 224 is provided at one end of the clamping tool rod 22 close to the slotting tool 32 , and a limiting groove 3212 corresponding to the limiting protrusion 224 is provided on the slotting tool 32 .

[0054] Specifically, both sides of the clamping tool bar 22 are provided with limiting protrusions 224, and the limiting grooves 3212 are provided on the tool holder 321 to limit the slotting tool 32. The purpose of this design is to ensure that the clamping tool bar 22 can be accurately positioned and fixed on the tool holder 321, so that the slotting tool 32 can be stably clamped and fixed at the required position, avoiding deviation or looseness caused by inaccurate alignment. The application of this design can improve the accuracy and reliability of tool assembly, reduce the debugging and calibration work when the tool is replaced, and also help improve the processing quality and efficiency.

[0055] In a specific embodiment, a fixing seat 211 is provided on the mounting plate 21 , and the clamping knife bar 22 is mounted on the fixing seat 211 , so that the mounting plate 21 and the clamping knife bar 22 are arranged in parallel.

[0056] Specifically, there are two fixing seats 211, which are respectively used to fix and connect the two ends of the clamping tool bar 22 to increase the support area of ​​the clamping tool bar 22, so as to make the structure of the tool assembly mechanism 2 more stable. At the same time, the clamping tool bar 22 and the mounting plate 21 are arranged in parallel, which ensures the precise position and angle of the planing tool 32 during the working process, thereby ensuring the accuracy and consistency of the cutting operation. This design can improve the processing efficiency and quality of cutting and reduce errors and losses.

[0057] In a specific embodiment, the tool body 322 includes a tool head portion 3221 fixed to the tool holder 321 and a tool grain portion 3222 disposed above the tool head portion 3221 , and the tool grain portion 3222 protrudes from the tool head portion 3221 .

[0058] Specifically, by arranging the blade grain portion 3222 above the blade head portion 3221, and the blade grain portion 3222 protruding from the blade head portion 3221, the friction between the tool body 322 and the workpiece surface is reduced, thereby improving the processing accuracy and the surface finish; in addition, it can also reduce the load on the grooving tool 32, help extend the service life of the tool body 322, reduce the risk of wear and breakage of the tool body 322, and improve safety.

[0059] In a specific embodiment, the tool loading disk 31 is circular, and the tool grain portion 3222 is disposed toward the center of the tool loading disk 31 .

[0060] Specifically, by arranging the tool body 322 toward the center of the tool loading disk 31, and the blade part 3222 pointing to the inside of the tool loading disk 31, when replacing the slotting tool 32, the tool loading disk 31 is rotated so that the handle of the slotting tool 32 to be replaced faces upward and the blade part 3222 faces downward, which is convenient for assembling the slotting tool 32, so that the tool assembly mechanism 2 (i.e., the cutting mechanism) can be directly put into cutting work after completing the tool assembly, so as to improve the cutting efficiency and cutting accuracy, and effectively avoid the collision or friction between the blade part 3222 and other parts or staff, thereby improving the safety of use. Preferably, the housing 34 is circular and is arranged concentrically with the tool loading disk 31, and the rotary motor 432 is connected to the center of the tool loading disk 31 by transmission, so that the tool loading disk 31 can rotate in the housing 34.

[0061] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
