[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] See also Figure 1-4The utility model discloses a turning tool structure with a wiping blade function, comprising: a tool bar body 1, a pressure plate 2, a blade 3 and a fixing screw 4 arranged between the tool bar body and the pressure plate. A mounting seat 5 is extended from the front end of the tool bar body. A step portion 6 for placing the blade is arranged on the mounting seat. The size of the step portion is adapted to the blade. A tool bar body slope 7 is arranged behind the step portion. A first mounting hole 8 is arranged on the pressure plate. A second mounting hole 9 for the fixing screw to pass through is opened at a corresponding position on the mounting seat. A protruding hook 10 for pressing and holding the blade is arranged at the front end of the pressure plate. A screw thread 10 is provided at the rear end of the pressure plate to be in close contact with the slope of the tool bar body. When operating, the fixing screw is passed through the first mounting hole and the second mounting hole and then tightened to fix the blade. The blade is pressed by the fixing screw above. At the same time, the protruding inclined surface behind the pressure plate contacts the slope of the tool rod body. When the pressure plate moves downward, the pressure plate can apply a tensioning force to the rear due to the contact movement of the inclined surface. A through hole 12 is provided on the blade. The protruding hook can hook the through hole in the middle of the blade when the pressure plate moves downward, so that the blade generates a force to fit the tool rod body to the right. Therefore, the blade not only has the surface pressing force applied by the pressure plate, but is also fixed by the tensioning force at the oblique rear. The overall blade is fixed quite stably.
[0022] Specifically, a positioning column 13 is provided on the protruding inclined surface, and a positioning hole 14 matching the positioning column is provided on the slope of the knife rod body. The positioning column and the protruding inclined surface on the pressure plate are integrally formed, and the protruding hook and the pressure plate are integrally formed. When the pressure plate moves downward, the protruding hook is used to fix the through hole of the blade, and the positioning column is inserted into the positioning hole and applies a tensioning force toward the rear under the contact movement of the inclined surface, so as to better fix the blade.
[0023] Specifically, an elastic member 15 is sleeved on the fixing screw, and the elastic member is restricted between the top cover of the fixing screw and the second mounting hole. The elastic member is a reset spring, and a spring is provided under the pressure plate. When the blade is removed, the pressure plate can always remain in an upward state under the action of the spring force, and the blade can be easily loaded and unloaded.
[0024] Specifically, the mounting seat and the tool rod body are an integrally formed structure, the bottom surface of the mounting seat is an arc-shaped surface, and the tool head portion where the blade contacts the turned product is an arc-shaped surface structure. The surface finish of the blade can not only meet the same original standards, but also improve the finish of the processed surface.
[0025] The beneficial effects of the utility model are as follows: the blade not only has the surface pressing force applied by the pressure plate, but also increases the tensioning force obliquely rearward of the force point, thereby ensuring the accuracy of installation and positioning, the blade fixing method is more stable, and the disassembly and assembly are relatively convenient, thereby improving the processing efficiency, reducing the cost and not affecting the life of the blade.
[0026] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
