The specific embodiment:
Below in conjunction with accompanying drawing, further set forth the specific embodiment of the invention.
As shown in Figure 2, a kind of quick clamping plate of the present invention comprise locating piece 1, fixed head 2, pressure strip 3, location wedge 5.
See also 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, rear fastening by bolt 25 cover Upper gaskets 22, and fixed head 2 is used for quick clamping plate of the present invention are installed to lathe.Be carved with scale and inclination biassed fabric for positioning mark on the wedge 5 of location, locating piece 1 is close on its inclined-plane, again by bolt 23, the fastening fixed head 2 that is installed to of pad 22, offer waist-shaped hole on fixed head 2, bolt 23 passes this waist-shaped hole and is screwed to location wedge 5, tighting a bolt 23, will to locate wedge 5 fixing, when needs are regulated this wedge 5 position, location, can unclamp this bolt 23, 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 is realized reorientating of location wedge 5.
But locating piece 1 is oppositely arranged holding cutter 4, mould or workpiece with the pressure strip 3 that is positioned at locating piece 1 front side, and this pressure strip 3 is divided into bare terminal end 31 and promote-side 32 along the middle part, and bare terminal end 31 forms the clamping matching relationship with the bottom of locating piece 1.a 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, offer the counterbore for retainer spring 16 on the groove bottom of locating slot 30, bolt 15 passes bare terminal end 31 from the opposing side of bare terminal end 31 and locating piece 1 slidably and is screwed on positioning strip (8), spring 16 is set on bolt 15, bare terminal end 31 and positioning strip 8 are supported respectively in two ends, the degree of depth that adjusting bolt 15 is screwed into positioning strip 8 makes the part of positioning strip 8 groove 30 inlay cards that are positioned, another part stretches out locating slot 30 and is used for aligned cutting tool, mould or workpiece, work as like this cutter, can guarantee when mould or workpiece are stressed 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 under spring 16 effects and being stretched out accordingly or retraction locating slot 30, thereby guarantee cutter, the adaptability of mould or workpiece error.Damage and 15 slips of assurance bolt to pressure strip 3 when sliding in order to reduce bolt 15 are smooth and easy, and fairlead 6 can be set on pressure strip 3, are used for guiding bolt 15 and slide, and 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, particularly, after bolt 21 wears convex pad 12, matrix pad 13, the through hole that passes again 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, make pressure strip 3 these bolt 21 swings relatively, thereby make the bare terminal end 31 of pressure strip 3 coordinate clamping with locating piece 1 or decontrol cutter, mould or workpiece.Be arranged with spring 18 on bolt 21, this bullet 18 two ends are supported respectively the middle part of pressure strip 3 and are screwed to locating piece 1, make like this pressure strip 3 can be relatively this bolt 21 have certain elasticity when swinging, swing softer, and when the clamping part change in size of cutter, mould or workpiece is larger, can regulate the distance of locating piece 1 and pressure strip 3 by the degree of depth that adjusting bolt 21 is screwed into locating piece 1, improve the quick clamping plate tool setting of the present invention tool, mould or the workpiece scope of application.
as shown in Fig. 6,7, push rod 7 is divided into positioning section 71, promotes section 72, extension 73, positioning section 71 slidably and be connected to rotationally the middle and upper part of locating piece 1 by bearing 10, promote section 72 radially than 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 is determined according to the push rod 7 axially movable distances of needs, that is pressure strip 3 needs the amplitude that swings and decides, and pressure strip 3 amplitudes of fluctuation are according to being clamped to the relieving cutter, distance between two extreme positions of mould or workpiece is determined, correspondingly, 1 of locating piece is provided with protuberance 11, the spin that in the present embodiment, protuberance 11 is rotatable inlay card on 1 of locating piece, rotating push-rod 7 can move along this groove 70 protuberance 11, thereby promote push rod 7 axially-movables, and then promote promote-side 32 and make bare terminal end 31 coordinate clamping die or cutter or workpiece with locating piece 1 away from locating piece 1.Certainly, groove 70 can exchange with the position of protuberance 11, be that groove 70 is arranged on locating piece 1, protuberance 11 is arranged on and promotes on section 72, same realization makes the axially movable function of push rod 7, the promote-side 32 that also can adopt the pushing mechanisms such as spring, eccentric wheel, eccentric shaft, linkage to promote pressure strip 3.
Extension 73 is extended to the promote-side 32 of pressure strip 3 and is run through this promote-side 32, on extension 73, cover has thrust bearing 14, conflict respectively and promote end face and the promote-side 32 of section 72 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 that is positioned at spanner 9 of promote-side 32 is provided with back-moving spring 19 and the bolt 20 that resets, pass promote-side 32 after the sheathed back-moving spring 19 of this bolt that resets and be screwed on locating piece 1, the nut section of promote-side 32 and the bolt 20 that resets is supported respectively at the two ends of back-moving spring 19.Rotating this spanner 9 can make push rod 7 rotate, axially move under protuberance 11 effects, when protuberance 11 along groove 70 during by dark and shallow slip, push rod is to moving 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 contraction distortion that is stressed, bare terminal end 31 coordinates clamping die, cutter or workpiece with locating piece 1; Along groove 70 during by shallow and dark the slip, the screen resilience of back-moving spring 19 makes promote-side 31 promote push rods 7 to moving near locating piece 1 direction when protuberance 11, bare terminal end 31 away from and discharge mould, cutter or the workpiece that is held.
