Detailed description of the invention:
Below in conjunction with accompanying drawing, set forth the specific embodiment of the invention further.
As shown in Figure 2, a kind of clamping plate fast of the present invention, comprise locating piece 1, fixed head 2, pressure strip 3, location wedge 5.
Refer to the main body that Fig. 2 to Fig. 5 locating piece 1 is quick clamping plate, fixed head 2 is sold 24 directly to households by elasticity and is positioned at locating piece 1 top, more fastening after overlapping Upper gasket 22 by bolt 25, and fixed head 2 is for being installed to lathe by quick clamping plate of the present invention.Location wedge 5 is carved with the scale for positioning mark and inclination biassed fabric, locating piece 1 is close on its inclined-plane, again by bolt 23, pad 22 is fastening is installed to fixed head 2, fixed head 2 offers waist-shaped hole, bolt 23 is screwed to location wedge 5 through this waist-shaped hole, tight a bolt and 23 location wedge 5 to be fixed, when needs regulate this wedge 5 position, location, this bolt 23 can be unclamped, moving bolt 23 along this waist-shaped hole makes location wedge 5 move along locating piece 1, after moving to correct position, then fastening bolt 23 realizes reorientating of location wedge 5.
Locating piece 1 and the pressure strip 3 be positioned on front side of locating piece 1 are oppositely arranged can holding cutter 4, mould or workpiece, and this pressure strip 3 is divided into bare terminal end 31 and promote-side 32 along middle part, bare terminal end 31 is formed with the bottom of locating piece 1 and clamps matching relationship.Side relative with locating piece 1 on bare terminal end 31 offers the locating slot 30 that can hold positioning strip 8, this locating slot 30 extends along the clamping face width of bare terminal end 31, the groove bottom of locating slot 30 is offered the counterbore for retainer spring 16, bolt 15 is screwed to positioning strip (8) from the side that bare terminal end 31 and locating piece 1 are opposing through bare terminal end 31 slidably, spring 16 is set on bolt 15, two ends support bare terminal end 31 and positioning strip 8 respectively, the degree of depth that adjusting bolt 15 is screwed into positioning strip 8 makes a part for positioning strip 8 by locating slot 30 inlay card, another part stretches out locating slot 30 for aligned cutting tool, mould or workpiece, work as cutter like this, mould or workpiece stressed time can ensure that positioning strip 8 can bear larger impulsive force, and work as cutter, when the clamping part of mould or workpiece has certain scale error, positioning strip 8 can be made and being stretched out accordingly or retraction locating slot 30 under spring 16 acts on, thus ensure cutter, the adaptability of mould or workpiece error.In order to reduce to slide smooth and easy to the damage of pressure strip 3 and guarantee bolt 15 when bolt 15 slides, can arrange fairlead 6 on pressure strip 3, for guiding bolt 15 to slide, this fairlead 6 in use can make the position of positioning strip 8 more stable.
The middle part of pressure strip 3 is hinged on described locating piece 1, specifically, after bolt 21 wears convex pad 12, matrix pad 13, through hole again through the middle part of pressure strip 3 is screwed on locating piece 1, the radial dimension of this through hole is more bigger than bolt 21, pressure strip 3 can be swung by this bolt 21 relatively, thus the bare terminal end 31 of pressure strip 3 is coordinated with locating piece 1 clamp or decontrol cutter, mould or workpiece.Bolt 21 is arranged with spring 18, these spring 18 two ends support middle part and the locating piece 1 of pressure strip 3 respectively, make pressure strip 3 can have certain elasticity when this bolt 21 swings relatively like this, swing softer, and when the clamping part change in size of cutter, mould or workpiece is larger, the degree of depth that can be screwed into locating piece 1 by adjusting bolt 21 regulates locating piece 1 and the distance of pressure strip 3, improves the present invention's quick clamping plate tool setting tool, mould or the workpiece scope of application.
As shown in Figure 6,7, push rod 7 is divided into positioning section 71, promotes section 72, extension 73, positioning section 71 slidably and be connected to the middle and upper part of locating piece 1 rotationally by bearing 10, the radial direction ratio promoting section 72 is greater than positioning section 71 and extension 73, end face near positioning section 71 is provided with by shallow and dark groove 70, the inclined degree of groove 70 needs the distance moved axially to determine according to push rod 7, that is pressure strip 3 needs the amplitude of swing and determines, and pressure strip 3 amplitude of fluctuation is according to being clamped to relieving cutter, distance between two extreme positions of mould or workpiece is determined, correspondingly, locating piece 1 is provided with protuberance 11, in the present embodiment, protuberance 11 is the spin of rotatable inlay card on locating piece 1, rotating push-rod 7 makes protuberance 11 can move along this groove 70, thus promote push rod 7 axially-movable, and then promote promote-side 32 and bare terminal end 31 is coordinated clamp mould or cutter or workpiece with locating piece 1 away from locating piece 1.Certainly, groove 70 can exchange with the position of protuberance 11, namely groove 70 is arranged on locating piece 1, protuberance 11 is arranged on and promotes in section 72, the function that same realization makes push rod 7 move axially, also can adopt the pushing mechanisms such as spring, eccentric wheel, eccentric shaft, linkage to promote the promote-side 32 of pressure strip 3.
Extension 73 extends to the promote-side 32 of pressure strip 3 and runs through this promote-side 32, on extension 73, cover has thrust bearing 14, conflict the end face and promote-side 32 that promote section 72 respectively in the two ends of this thrust bearing 14, the part that promote-side 32 is stretched out in extension 73 is fixed with spanner 9 by jackscrew 17; The adjacency being positioned at spanner 9 of promote-side 32 is provided with back-moving spring 19 and reset bolt 20, be screwed on locating piece 1 through promote-side 32 after the sheathed back-moving spring 19 of this reset bolt, the nut portion of promote-side 32 and reset bolt 20 is supported at the two ends of back-moving spring 19 respectively.Rotating this spanner 9 can make push rod 7 rotate, move axially under protuberance 11 acts on, when protuberance 11 along groove 70 by dark and shallow slip time, push rod moves to away from locating piece 1 direction, thrust bearing 14 on extension 73 promotes promote-side 32 away from locating piece 1, back-moving spring 19 is stressed contraction distortion, and bare terminal end 31 coordinates with locating piece 1 and clamps mould, cutter or workpiece; When protuberance 11 along groove 70 by shallow and when deeply sliding, the screen resilience of back-moving spring 19 makes promote-side 31 promote push rod 7 to move to close to locating piece 1 direction, bare terminal end 31 away from and release by the mould, cutter or the workpiece that clamp.
