Description

Technical Field

[0001] The utility model relates to the technical field of T-shaped knives, in particular to a retractable beveled T-shaped knife. Background Art

[0002] With the development of machining technology, CNC machine tools have emerged. CNC machine tools are automated machines equipped with a program control system that can operate and process parts according to a pre-programmed program. Traditionally, CNC machine tools require T-type cutters when machining internal circular grooves. However, current T-type cutters are integrated, requiring different cutter heads to machine internal circular grooves of different diameters.

[0003] An existing patent (publication number CN204183004U) discloses a retractable beveled T-cut tool. The cylindrical section can slide in the cylindrical cavity, the screw can move in the axial through-hole, and the cutter head moves axially in the tool handle via the screw. The screw is braked by a braking mechanism, thereby achieving axial retraction of the T-cut tool. This allows for convenient processing of T-slots of different depths without having to replace the tool, greatly improving processing efficiency.

[0004] However, there are some problems in the use of existing T-shaped knives: 1. When the knife rod of the current T-shaped knife is extended or retracted, the extended length is adjusted by pulling the rod body in the telescopic slot, and then the fastening bolts arranged on the side of the telescopic slot are squeezed on the surface of the telescopic rod to clamp and position the telescopic rod to achieve telescopic fixation. However, the fastening bolts do not directly penetrate the telescopic rod, so the positioning of the telescopic rod is limited, affecting the stability of use; 2. The existing T-shaped knife can only adjust the length and telescopic size of the knife rod, but the rotation radius of the knife head cannot be directly adjusted, so it is necessary to replace the knife body of different models, and the repeated disassembly and assembly process brings inconvenience to the processing process. Utility Model Content

[0005] The purpose of the present invention is to provide a retractable beveled T-shaped knife to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: comprising a knife bar, a telescopic assembly arranged inside the knife bar, a top plate fixedly mounted on the upper end surface of the telescopic assembly, and a distance adjustment assembly arranged inside both sides of the top plate;
