In figure: double acting flat-nose pliers 10, clamp block 11, double V-shaped jaw 12, work retainer 20, location mandril 21, angular adjustment knob 22, dial 23, set lever 24, workpiece assembly 30, contiguous block 31, positive stop 32, draw-in groove 33, locating dowel 34, workpiece 100, milling cutter 101.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As depicted in figs. 1 and 2, a kind of keyseat clamp, comprise double acting flat-nose pliers 10, described double acting flat-nose pliers 10 comprises clamp block 11 and is arranged on the double V-shaped jaw 12 in clamp block 11, double V-shaped jaw 12 energy clamping work pieces 100, clamp block 11 is also connected with work retainer 20, described work retainer 20 has revolvable location mandril 21, the shape of described location mandril 21, the die cavity of size and workpiece 100 matches, when location mandril 21 is inserted into the die cavity of workpiece 100, the center line of workpiece 100 is located fixing, and described location mandril 21 can rotating in a circumferential direction along the center line of double V-shaped jaw 12, namely the machined surface of workpiece 100 can rotate adjustment, very convenient.
Prior art is when processing the keyway of workpiece 100 of different-diameter, because adopt common flat-nose pliers, need the symmetry readjusting keyway and workpiece 100 diameter, and double V-shaped jaw 12 of the present invention can determine the height of workpiece 100, this height can not change because the diameter of workpiece 100 changes, the center line of workpiece 100 also can be ensured by location mandril 21 in addition, thus centrad that processing work 100 is and symmetry are all remained unchanged, and improves operating efficiency and machining accuracy.
Work retainer 20 is provided with the angular adjustment knob 22 be connected with location mandril 21, and when angular adjustment knob 22 rotates, location mandril 21 also rotates thereupon.Work retainer 20 is also provided with dial 23 and the position of this dial 23 is corresponding with the position of angular adjustment knob 22, the angle that can accurately be rotated by dial 23, improves precision.Work retainer 20 is provided with set lever 24, when set lever 24 rotates forward or backwards, work retainer 20 can be locked or be unclamped location mandril 21, in keyseat process, want the milling face of first positioning workpieces 100, when the position of location mandril 21 is fixed, workpiece 100 also can be fixed, thus the milling face of making is fixed, be convenient to processing.
Clamp block 11 is also connected with a workpiece assembly 30, described workpiece assembly 30 be located at clamp block 11 away from the end face of work retainer 20 and workpiece assembly 30 just to the center line of double V-shaped jaw 12, namely workpiece 100 can not depart from double V-shaped jaw 12.Workpiece assembly 30 comprises the contiguous block 31 removably connected with clamp block 11 bolt pair, described contiguous block 31 is connected with positive stop 32 and the center line of positive stop 32 overlaps with the center line of double V-shaped jaw 12, as longer in workpiece 100, also can pull down contiguous block 31, abandon location.The end of contiguous block 31 has draw-in groove 33, and positive stop 32 has away from one end of workpiece 100 and can block as to the locating dowel 34 in draw-in groove 33.
The course of work of the present invention is:
Be inserted into by the die cavity of workpiece 100 on location mandril 21, rotational angle adjusting knob 22 makes the keyseat of workpiece 100 in the face of accurate milling cutter 101, and locking set lever 24 makes location mandril 21 fix.
Double V-shaped jaw 12 clamping work pieces 100, carries out keyseat operation with milling cutter 101 pairs of workpiece 100.
When in keyseat process, if will adjust the milling face of workpiece 100, can unclamp double V-shaped jaw 12, rotational angle adjusting knob 22 can realize, and the center line of workpiece 100 and highly all can not changing.
If will carry out spacing to the processing length of workpiece, availablely prop up workpiece 100, for limiting when the displacement of workpiece 100 is to contact with positive stop 32.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Although more employ the terms such as double acting flat-nose pliers 10, clamp block 11, double V-shaped jaw 12, work retainer 20, location mandril 21, angular adjustment knob 22, dial 23, set lever 24, workpiece assembly 30, contiguous block 31, positive stop 32, draw-in groove 33, locating dowel 34, workpiece 100, milling cutter 101 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
