Embodiment Construction
[0012] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0013] Such as Figure 1 to Figure 3 As shown, the adjustable planer according to the present invention mainly includes a cutter head 1, a cutter holder 2, a cutter head 3, a cutter body 4, and a locking screw 5, and its detailed structure is described as follows:
[0014] The cutter head 1 is a common planer. The tool holder 2 is provided with an upper part with a certain oblique taper, a substantially cylindrical lower part, and a stop part 21 at the bottom of the lower part with a slightly larger diameter than the lower part. The middle part of the knife case 2 is provided with a substantially transversely extending square groove 22 , and the upper center of the knife case 2 is screwed with a fastening screw 23 substantially extending longitudinally. The cross-section of the cutter head 3 is L-shaped, and the first part of the L-shape bas...

The invention relates to an adjustable plane cutter, which comprises a tool bit, a cutter case, a cutter, a cutter body, lock bolts and the like. An upper part of the cutter case is of an oblique cone shape, a lower part is of a cylinder shape, and a middle part is provided with a square slot for the tool bit to insert; and the upper part is provided with a fastening screw for fixing the tool bit on the cutter, and the bottom of the lower part is provided with a stop part. The section of the cutter is of an L shape and comprises a first part and a second part which are basically vertical with each other; a front end near the first part is provided with a through hole which is basically extended vertically for the cutter case to insert; and the second part is a cylinder connecting end, and a matching surface of a rear end corresponds to a matching surface of one end of the cutter body. The adjustable plane cutter is characterized in that: a plurality of circular arc kidney slots are uniformly arranged on a cutter body connecting end, and a cutter connecting end is provided with a plurality of corresponding threaded holes; and a plurality of lock bolts pass through each kidney slot of the cutter body connecting end and are in threaded connection with the corresponding threaded holes of the cutter connecting end, so that the cutter can be rotated relative to the cutter body in an angle range which is defined by the kidney slots to adjust a tool cutting edge inclination angle and a deflection angle of the plane cutter.
Description
technical field [0001] The invention relates to the field of metal cutting, in particular to a planer for metal cutting. Background technique [0002] The planer is a common tool in metal cutting. For the planer used in various types of planers, it may be desirable to properly adjust the blade inclination and deflection angle of the planer to meet the needs of different workpiece materials and different machining accuracy. In the prior art, there are already some clamp-type planers with adjustable blade inclination angles. For example, Chinese Utility Model Patent No. 02233810.1 discloses a clamp-type planer with adjustable angle. Its main structural features are: the cutter head is long, The rake face is platform-shaped, and the main cutting edge is at both ends of the face in the length direction. The clamped slopes on both sides are dovetail-shaped, and the bottom surface has stop teeth. Clamping the inclined block and the stop block can firmly clamp the cutter head; the...
