Abstract
The utility model relates to a fixture used in the processing process of a machine tool. The fixture comprises a positioning piece and a clamping part, wherein the positioning piece comprises a first positioning rod, a second positioning rod and a connecting rod for connecting the first positioning rod and the second positioning rod; the positioning piece is I-shaped; mutually parallel threaded through holes are symmetrically arranged at the two ends of the first positioning rod; the axial direction of each threaded through hole is parallel to the connecting rod; the clamping part comprises screw rods and clamping heads; the screw rods and the clamping heads are symmetrically arranged through the connecting rod as an axial line; the screw rods are connected with the threaded through holes through threads; one end of one screw rod and one end of the other screw rod positioned at the inner side of the positioning piece are connected with the clamping heads; and the clamping heads are plate-shaped and are vertical to axial lines of the screw rods. As the positioning piece is I-shaped, the positioning piece can clamp two workpieces with parallel planes; and the bending moments caused by clamping forces of the clamping heads at the two ends can be mutually neutralized, so that the positioning piece is uniformly stressed. The positioning piece also can simultaneously clamp the two workpieces so as to improve the work efficiency. The fixture has the advantages of simple structure, large clamping force, reliable clamping and wide use scope.
Description
Technical field
Used anchor clamps when the utility model relates to a kind of machine tooling.
Background technology
Need a kind of anchor clamps to clamp during machine tooling and have two plane-parallel workpiece,, also do not have this clamping device on the domestic and international market at present so that accomplish work such as welding, boring, recontour.
The utility model content
The utility model provides a kind of can clamp the anchor clamps with two plane-parallel workpiece.
The utility model solves the technical scheme that its technical problem adopted and provides a kind of anchor clamps; Comprise keeper and clamping part; Said keeper comprises first backstay, second backstay and connects first backstay and the connecting rod of second backstay, the whole one-tenth of said keeper " worker " font; The two ends of said first backstay are symmetrically arranged with the tapped through hole that is parallel to each other, said tapped through hole axially parallel with connecting rod; Said clamping part comprises screw rod and chuck; Said screw rod and chuck are the axial symmetry setting with the connecting rod; Said screw rod and screwed hole are through being threaded, and the inboard end of keeper that is positioned at of said screw rod is connected with chuck, and said chuck is tabular and perpendicular to the axis of screw rod.
Further, an end that is positioned at the keeper outside of said screw rod is provided with cross through hole, is provided with the handle that flexibly connects with cross through hole in the said cross through hole.
Further, position relative with chuck on said second backstay is provided with boss, and said boss is provided with cushion pad.
Because keeper be " worker " font, can clamp and have two plane-parallel workpiece, can cancel out each other by the moment of flexure that the clamping force of two ends chuck causes, make keeper stressed even.This keeper can also clamp two workpiece simultaneously, increases work efficiency; The clamp structure that the utility model proposes is simple, and clamping force is big, reliable clamping, and the scope of application is wide.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Accompanying drawing 1 is the front view of the utility model.
Accompanying drawing 2 is left views of the utility model.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
As depicted in figs. 1 and 2: anchor clamps comprise keeper and clamping part, and keeper comprises first backstay 41, second backstay 42 and the connecting rod 7 that connects first backstay 41 and second backstay 42, and keeper is whole to become " worker " font; The two ends of first backstay 41 are symmetrically arranged with the tapped through hole 51,52 that is parallel to each other, said tapped through hole 51,52 axially parallel with connecting rod 7; Clamping part comprises screw rod 21,22 and chuck 31,32; Screw rod 21,22 and chuck 31,32 are the axial symmetry setting with connecting rod 7; Screw rod 21,22 and screwed hole 51,52 are through being threaded; The inboard end of keeper that is positioned at of screw rod 21,22 is connected with chuck 31,32, and chuck 31,32 is tabular and perpendicular to the axis of screw rod 21,22.
During work, will have the angle that two plane-parallel workpiece are put into keeper, rotating screw bolt clamps two chucks, process workpiece after, rotating screw bolt makes two chucks unclamp workpiece.
In the time of need processing two workpiece simultaneously, two workpiece are put into chuck 31 and 32 belows respectively, rotating screw bolt clamps two chucks, process workpiece after, rotating screw bolt makes two chucks unclamp workpiece.
An end that is positioned at the keeper outside of screw rod 21,22 is provided with cross through hole, is provided with the handle 11,12 that flexibly connects with cross through hole in the cross through hole.During work, hold the handle rotating screw bolt, being provided with of handle can make rotating screw bolt more laborsaving.
The position relative with chuck is provided with boss 61,62 on second backstay 42, and boss 61,62 is provided with cushion pad; Like this when clamping work pieces owing to there is cushioning effect to make workpiece not yielding.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
