Detailed description of the invention
embodiment 1
See Fig. 2, Fig. 3: the utility model is used for the clamping of sheet workpiece plane machining (as plane milling), it comprises pedestal 1, cushion 2 and liquid/gas cylinder pressure 5(and hydraulic cylinder or pneumatic cylinder, according to coupling mechanism force size, usually selects hydraulic cylinder).
Wherein, pedestal 1, in the L shape lain low, has horizontal surface and the vertical plane perpendicular to horizontal surface.The horizontal surface of pedestal 1 is for assembling cushion 2, and the part at corresponding cushion 2 top of vertical plane is used for arranging location jaws 3.The effect of this location jaws 3 has two, one, for the vertical plane of cushion base 1, guarantees that the vertical plane of pedestal 1 can keep smooth for a long time, and then extends the service life of pedestal 1; They are two years old, on the face of cushion 2, the miniature vertical groove of at least one (according to jam-packed cushion block 6 quantity) (thickness profile of the corresponding jam-packed cushion block 6 of width) is provided with in location jaws 3, for locating following jam-packed cushion block 6, avoid following jam-packed cushion block 6 under the effect of high strength jam-packed power that deviation phenomenon occurs.
Liquid/gas cylinder pressure 5 is horizontally disposed, the top of its piston rod and the vertical plane of pedestal 1 are in opposite directions, the top of piston rod is connected to the back side central authorities of location jaws 3 for arranging location jaws 3(piston rod, basic goal is that the jam-packed power of liquid/gas cylinder pressure 5 is disperseed uniformly to the front of location jaws 3).The same, the effect of this location jaws 3 has two, one, for the piston rod top of liner liquid/gas cylinder pressure 5, guarantees that the piston rod end face of liquid/gas cylinder pressure 5 can keep smooth for a long time, and then extends the service life of liquid/gas cylinder pressure 5; They are two years old, on the face of cushion 2, the miniature vertical groove of at least one (according to jam-packed cushion block 6 quantity) (thickness profile of the corresponding jam-packed cushion block 6 of width) is provided with in location jaws 3, for locating following jam-packed cushion block 6, avoid following jam-packed cushion block 6 under the effect of high strength jam-packed power that deviation phenomenon occurs.
On the horizontal surface of cushion 2 by securing member mounted base 1 such as bolts, its rigging position neither contacts with the vertical plane of pedestal 1, also not with the plunger rod contacts of liquid/gas cylinder pressure 5, namely require that the cushion 2 assembled keeps certain distance (occurrence according to processing live choose reasonable, but must not be less than jam-packed force-stroke) respectively with the vertical plane of pedestal 1 and the piston rod of liquid/gas cylinder pressure 5.The end face size of aforementioned cushion 2 is greater than the planar dimension of sheet workpiece 4, and the end face of cushion 2 is for placing sheet workpiece 4.
The thickness of sheet workpiece 4 is generally 3 ~ 5mm, and concrete thickness is determined according to processed sheet workpiece 4.Sheet workpiece 4 pass on left at least one piece in obtuse angle leg-of-mutton jam-packed cushion block 6(be generally one piece, if during polylith, their specification must be identical and position must be corresponding consistent) be connected in the vertical plane location jaws 3 of pedestal 1, jam-packed cushion block 6 is installed in the groove of location jaws 3; The right side of sheet workpiece 4 by least one piece in obtuse angle leg-of-mutton jam-packed cushion block 6(be generally one piece, if during polylith, their specification must be identical and position must be corresponding consistent) be connected in the piston rod location jaws 3 of liquid/gas cylinder pressure 5, jam-packed cushion block 6 is installed in the groove of location jaws 3, under the effect of liquid/gas cylinder pressure 5, sheet workpiece 4 squeezed gripping between the vertical plane and the piston rod of liquid/gas cylinder pressure 5 of pedestal 1 is held, and then forms firm, reliable smooth clamping.
Firm, the reliable smooth clamping of above-mentioned sheet workpiece 4 depends on can realize level to the jam-packed cushion block 6 with oblique vertical lower component.This jam-packed cushion block 6 is obtuse triangle structure, has an obtuse angle a, a large acute angle b and little acute angle c; Wherein, the value of obtuse angle a is 91 ~ 95 °, the words (such as 90 °) that this value is too small, level can only be formed when jam-packed to jam-packed power, cannot component be realized, the words (such as 120 °) that this value is excessive, though active component can be realized reliably, but clamping difficulty will be caused to increase, and especially easily there is beat, even jump and the phenomenon such as to fly in jam-packed cushion block under larger jam-packed power, thus preferably 92 °, 93 ° or 94 ° etc. in aforementioned zones; The common value of large acute angle b is about 70 ° (such as 65 ~ 75 °); Little acute angle c is used for contact sheet workpiece 4 when clamping, its value is about 15 ° (such as 24 ~ 10 °), sheet workpiece 4 is held out against firmly, reliably in order to enable the little acute angle c of jam-packed cushion block 6, and realize prolonged and repeated use, little acute angle c can not adopt horn structure, and rounding structure should be adopted, rounding radii is generally 0.5 ~ 1.5mm, this value is too small can not guarantee the reliability of jam-packed cushion block 6 clamping and service life short, this value crosses conference affects component situation, preferred 0.7mm, 1mm or 1.3mm etc. in aforementioned range.
embodiment 2
Other structure of the present embodiment is identical with embodiment 1, and difference is: the location jaws on pedestal vertical plane is burnishing surface towards the face of cushion; When clamping, the left side of sheet workpiece is directly connected in the location jaws of pedestal vertical plane, pass through one piece of jam-packed cushion block jam-packed by the piston rod of liquid/gas cylinder pressure on the right side of sheet workpiece, and then make sheet workpiece realize clamping clamping between the vertical plane and the piston rod of liquid/gas cylinder pressure of pedestal.Though the present embodiment can utilize point force characteristic of jam-packed cushion block to realize comparatively firm, reliable smooth clamping to sheet workpiece, clamping effect is not as good as embodiment 1.
The various embodiments described above only in order to the utility model to be described, are not intended to limit.Although be described in detail the utility model with reference to the various embodiments described above, those of ordinary skill in the art is to be understood that: it still can be modified to the concrete technical scheme of the various embodiments described above, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of technical solutions of the utility model.
