Detailed Description
The invention will be described in further detail with reference to the following description of the drawings, it being understood that the described embodiments are merely individual embodiments of the invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the scope of the invention.
As shown in the figure, the clamping type cutter for woodworkers comprises a cutter frame 1, a blade 2 and a pressing block 3, wherein a shaft hole 4 is formed in the center of the cutter frame 1, a plurality of clamping parts 5 are arranged on the cutter frame 1, and positioning ejector pins 6 are arranged on the side surfaces of the clamping parts 5; the blade 2 is arranged on the clamping part 5, and the pressing block 3 is arranged on the blade. The clamping type cutter accurately fixes the blade 2 in multiple directions, the axial positioning precision of the blade 2 is controlled by the positioning ejector pin 6, the radial positioning precision of the cutter is controlled by the pressing block 3, the position of the blade 2 is more accurate and stable, and the overall working efficiency of the cutter is improved.
In some embodiments, the blade 2 is provided with a positioning groove 7, and the pressing block 3 is provided with a positioning reference line 8 which is matched with the positioning groove 7. By means of the positioning groove 7 and the positioning reference line 8, the pressing acting force of the pressing block 3 is not limited on the contact surface of the pressing block and the blade 2, the situation that the blade 2 slides up and down is avoided, and the position stability of the pressing block is further improved.
In some embodiments, the clamping portion 5 is provided with a plurality of positioning screw holes 9, and the pressing block 3 is provided with screw holes 10, which have the same number as the positioning screw holes 9 and are used in cooperation therewith. The pressing block 3 is fixed on the clamping part 5 by screws, and the pressing block 3, the blade 2 and the tool rest 1 are fixed into a whole by screwing the screws.
