[0002] In machining, it often happens that the size and shape of the groove do not match those of the standard grooving blade, such as the size of the groove width not matching, the transition fillet at the bottom of the groove not being standard, etc. Using a non-standard grooving tool can accurately match these special requirements and ensure machining accuracy and efficiency;

[0003] When machining a workpiece, because the grooving tool is relatively straight, it is difficult to machine some special workpieces, which not only results in low machining efficiency but also affects the machining accuracy;

[0004] To solve the above defects, a non-standard turning tool for inclined holes and grooves, with the publication number CN218926274U, through the mutual cooperation between the tool body, chip flutes, cooling holes, blade and the arc-shaped supporting tool body, enables the turning tool to perform inclined hole cutting with a fixed inclination angle for parts, thus solving the problems of high difficulty and low accuracy when using existing ordinary turning tools for inclined hole cutting;

[0005] In the actual use of the above device, although the blade is used to machine special workpieces, however, the blade is inclined, so only the workpiece can be inclined for cutting. When it is necessary to groove the workpiece, the blade needs to be replaced, which will lead to inconvenient machining.

[0006] Therefore, we propose that the non-standard grooving tool can well solve the above problems. Content of the Utility Model

The blade 3 can groove the workpiece, and the blade 3 will be clamped with the tool groove 2, thereby improving the stability of the blade 3 and thus improving the convenience of machining;

[0035] Embodiment Two: The present utility model solves the problem that the disassembly and assembly of the existing blade 3 are not convenient enough. By means of a pin 4, the disassembly and assembly of the blade 3 can be facilitated, and it is disclosed that:

[0036] A pin 4 penetrates through the middle of the blade 3, and the top of the pin 4 extends into the inside of the tool shank 1, and the top of the pin 4 extends into the positioning groove 5 to form a clamping engagement, and the positioning groove 5 is opened inside the tool shank 1;

[0037] Reference Figures 1 to 4 , when pulling the pin 4, the movement of the pin 4 will disengage from the inside of the tool shank 1, and the movement of the pin 4 will disengage from the clamping engagement with the positioning groove 5, and then the pin 4 is pulled out from the blade 3, so that the blade 3 can be disassembled and replaced. By reversing the above operations, the blade 3 can be fixed inside the tool groove 2 to achieve the purpose of installation, thereby improving the convenience of installation;

[0038] Embodiment Three: The present utility model solves the problem that the stability of the pin 4 in Embodiment Two is relatively poor. By the movement of a fixing block 13, the clamping stability of the pin 4 can be improved, and it is disclosed that:

[0039] A plug pin 6 is slidably connected inside the pin 4, and a slider 7 is fixed to the bottom of the plug pin 6, and the outer end of the slider 7 extends into the inside of a chute 8 to form a clamping mechanism. Moreover, the chute 8 is opened inside the pin 4. A convex block 9 is slidably connected inside the slider 7, and the outer end of the convex block 9 extends into the inside of a groove 10 to form a clamping mechanism. And the outer end of the convex block 9 is semicircular in shape. The groove 10 is opened inside the pin 4. The inner end of the convex block 9 is connected to a first spring 11, and the inner end of the first spring 11 is connected inside the slider 7. A pull rope 12 is attached to the top of the plug pin 6, and the pull rope 12 is slidably connected inside the pin 4, and the outer end of the pull rope 12 is connected to the inner end of a fixing block 13.

[0040] Reference Figures 1 to 7, by rotating the bolt 6, the rotation of the bolt 6 drives the slider 7 to slide inside the chute 8, and then the rotation of the slider 7 drives the convex block 9 to rotate. As a result, the rotation of the convex block 9 squeezes against the groove 10, and then the convex block 9 is squeezed and slides into the slider 7. Then, the movement of the convex block 9 causes it to disengage from the engagement with the groove 10, and the movement of the convex block 9 squeezes the first spring 11, causing the first spring 11 to be compressed under force. Then, press the bolt 6 so that the bolt 6 can slide inside the chute 8 through the slider 7, so that the movement of the bolt 6 squeezes the pull rope 12. Then, the movement of the pull rope 12 drives the fixed block 13 to move, and then the movement of the fixed block 13 causes it to disengage from the engagement with the tool bar 1, and the movement of the fixed block 13 squeezes the second spring 14, causing the second spring 14 to be compressed under force. Thus, the retaining pin 4 can be pulled out of the retaining pin 4, and by reversing the above operations, the slider 7 is engaged inside the chute 8. Then, the first spring 11 pushes the convex block 9 to extend into the groove 10 to form an engagement, and the bolt 6 disengages from the extrusion of the pull rope 12. Then, the second spring 14 pushes the fixed block 13 to extend into the tool bar 1 to form an engagement, thereby fixing the retaining pin 4.

[0041] Working principle: When using this non-standard grooving tool, first, refer to Figures 1 to 3 , fix the tool bar 1 on the numerically controlled machine tool, and then the rotation of the workpiece cuts with the blade 3. The blade 3 can groove the workpiece, and the blade 3 is engaged with the tool groove 2, thereby improving the stability of the blade 3;

[0042] Refer to Figures 1 to 4 , when pulling the retaining pin 4, the movement of the retaining pin 4 causes it to disengage from the inside of the tool bar 1, and the movement of the retaining pin 4 causes it to disengage from the engagement with the positioning groove 5. Then, pull out the retaining pin 4 from the blade 3, and then the blade 3 can be disassembled and replaced, thereby improving the installation convenience;

[0043] Refer to Figures 1 to 7, by rotating the bolt 6, the rotation of the bolt 6 drives the slider 7 to slide inside the chute 8, and then the rotation of the slider 7 drives the convex block 9 to rotate. Then, the convex block 9 is squeezed and slides into the slider 7. Then, the movement of the convex block 9 causes it to disengage from the engagement with the groove 10. Then, the bolt 6 is pressed, so that the bolt 6 can slide inside the chute 8 through the slider 7. Then, the movement of the pull rope 12 drives the fixed block 13 to move. Then, the movement of the fixed block 13 causes it to disengage from the engagement with the tool bar 1. And by reversing the above operations, the slider 7 is engaged inside the chute 8. Then, the convex block 9 is pushed by the first spring 11 to extend into the groove 10 to form an engagement, and the bolt 6 disengages from the extrusion of the pull rope 12. Then, the fixed block 13 is pushed by the second spring 14 to extend into the tool bar 1 to form an engagement, so as to fix the latch 4.
