Description
Technical field
The invention belongs to field of fixtures, be specifically related to a kind of multi-purpose fixture regulating clamping face.
Background technology
Be used for fixing processing object in machine-building process, make it to occupy correct position, to accept the device of constructing or detecting, also known as jig.In a broad sense, any operation in technical process, is used for rapidly, installs easily and safely the device of workpiece, all can be described as fixture.Such as weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often referred to as fixture.On lathe during processing work, the dimensions reaching drawing for making the surface energy of workpiece and specify, geometry and with the technical requirements such as the relative-position error on other surfaces, workpiece must be installed (location) before processing, clip (clamping).Fixture is usually by compositions such as setting element (determining the tram of workpiece in fixture), clamping device, tool setting induction element (determine the relative position of cutter and workpiece or guide tool orientation), indexing means (make workpiece can complete the processing of several station in once mounting, have circular index device and rectilinear movement indexing means two class), Connection Element and clamp bodies (clamp base).
Existing fixture carries out design clamping face according to the type of workpiece usually, therefore, the type of fixture is many, wide in variety, and the fixture of each type also can be inconsistent according to the surface configuration of workpiece, and segment the clamping face of multiple shape again, thus cause that type is many, kind is many, find the fixture difficulty of applicable workpiece large, complicated operation.
Summary of the invention
The technical problem to be solved in the present invention be many for the type of existing fixture, kind is many, the defect of troublesome poeration, provides a kind of multi-purpose fixture that can carry out the adjustment clamping face of the clamping face shape of alignment jig according to the type of workpiece.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: the multi-purpose fixture regulating clamping face, comprise pedestal, train wheel bridge and lower plate, the upper end of pedestal is provided with groove, and lower plate is positioned at groove, is provided with back-moving spring between the lower end of lower plate and the bottom of groove, the both sides of lower plate are all hinged with the cell wall of groove, the upper end of lower plate is provided with lower chuck, and lower chuck comprises pressure ball under lower soft outer and a group, and lower pressure ball is positioned at lower soft outer; The side of pedestal is vertically provided with slide bar, and slide bar is arranged with sliding sleeve, and sliding sleeve connects in slide bar, and the lower end of train wheel bridge is provided with upper grip, and upper grip comprises soft outer and one group of upper pressing ball, and upper pressing ball is positioned at soft outer.
Adopt the multi-purpose fixture of the adjustment clamping face of technical solution of the present invention, train wheel bridge slides by being sheathed on sliding on slide bar on slide bar, thus make train wheel bridge and lower plate close, workpiece is then installed between train wheel bridge and lower plate, and upper pressing ball is positioned at soft outer, lower pressure ball is positioned at lower soft outer, because spheroid is in soft shell, when being under pressure, run to pressure little place extruding, therefore, when workpiece is by top board and lower platen clamping, then upper sphere and lower sphere distribute in upper soft outer and lower soft outer according to the shape of workpiece, thus with the form fit of workpiece, form new clamping face, back-moving spring between lower plate and bottom portion of groove, give the effect of lower plate buffering, when lower plate is under pressure, back-moving spring is in compressive state, give the opposition of lower plate, thus make Workpiece clamping effective.Compared with existing polytype fixture, upper pressing ball of the present invention and lower pressure ball are in upper soft outer and in lower soft outer, shaping according to the surface configuration Tissue distribution of workpiece, thus are formed at the clamping face that workpiece matches, and applicability is strong, and clamping effect is good.
Further, described lower plate and train wheel bridge are hollow plywood.Hollow plywood does not affect the intensity of clamping on the one hand, and save material on the other hand, cost is low.
Further, be provided with one group of lower protruding block and lower spring between described lower soft outer and lower plate, one end of lower spring is connected with the lower end of lower protruding block, and the other end lower plate of lower spring connects.Lower protruding block and lower spring are when being subject to clamping force with workpiece, and back-moving spring compresses reverse elastic force, thus make clamping effect better.
Further, be provided with one group of upper protruding block and upper spring between described upper soft outer and train wheel bridge, one end of upper spring is connected with the upper end of upper protruding block, and the other end train wheel bridge of upper spring connects.Same reason, upper spring and upper protruding block make clamping effect better.
Further, described upper pressing ball and lower pressure ball are hollow ball.While not affecting clamping force, save cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is the schematic diagram that the present invention regulates the multi-purpose fixture embodiment of clamping face.
Detailed description of the invention
In figure: train wheel bridge 1, lower plate 2, back-moving spring 3, lower soft outer 4, lower pressure ball 5, upper soft outer 6, upper pressing ball 7, lower spring 8, upper spring 9, upper protruding block 10, lower protruding block 11.
As shown in Figure 1, the present invention regulates the multi-purpose fixture of clamping face, comprise pedestal, train wheel bridge 1 and lower plate 2, the upper end of pedestal is provided with groove, lower plate 2 and train wheel bridge 1 are hollow plywood, lower plate 2 is positioned at groove, back-moving spring 3 is provided with between the lower end of lower plate 2 and the bottom of groove, the both sides of lower plate 2 are all hinged with the cell wall of groove, the upper end of lower plate 2 is provided with lower chuck, lower chuck comprises pressure ball 5 under lower soft outer 4 and a group, lower pressure ball 5 is positioned at lower soft outer 4, one group of lower protruding block 11 and lower spring 8 is provided with between lower soft outer 4 and lower plate 2, one end of lower spring 8 is connected with the lower end of lower protruding block 11, the other end lower plate 2 of lower spring 8 connects, the side of pedestal is vertically provided with slide bar, slide bar is arranged with sliding sleeve, sliding sleeve connects in slide bar, the lower end of train wheel bridge 1 is provided with upper grip, upper grip comprises soft outer 6 and one group of upper pressing ball 7, upper pressing ball 7 is hollow ball, upper pressing ball 7 is positioned at soft outer 6, lower soft outer 4 adopts soft plastic to make, upper soft outer 6 adopts soft plastic to make, one group of upper protruding block 10 and upper spring 9 is provided with between upper soft outer 6 and train wheel bridge 1, one end of upper spring 9 is connected with the upper end of upper protruding block 10, the other end train wheel bridge 1 of upper spring 9 connects, upper pressing ball 7 is hollow ball.
