Description
Technical field
The present invention relates to mechanical clamp, be specifically related to a kind of spherical fixture.
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).
An existing special workpiece, as shown in workpiece in Fig. 1 in accompanying drawing, this workpiece main body is that spherical, spherical low side has a base.Conventional clamp fixture cannot clamping it its fast and stable.Add man-hour to workpiece stressed comparatively large, common holder all easily relaxes, and the workpiece accuracy processed is not high.
Summary of the invention
The object of the present invention is to provide clamping process simple, the fixture that clamping is not easily lax.
The present invention is achieved by the following technical solutions: spherical fixture, comprise bottom base, upper cover and clamp shaft, wherein, bottom base is provided with the standing groove placing spherical work-piece, upper cover is fixedly connected with bottom base, upper cover is provided with workpiece slot, the workpiece slot of upper cover and the standing groove of bottom base form the cavity that can hold workpiece, upper cover is provided with an inclined hole, clamp shaft is provided with in inclined hole, clamp shaft is divided into clamping part and drive part, the inwall of clamping part and inclined hole is slidably connected, clamping part is provided with the horizontal seal face coordinated with workpiece base end face, the end cap that drive part runs through inclined hole is placed in outside inclined hole, drive part is fixedly connected with drive unit.
The invention has the beneficial effects as follows: the reaction force of common clamp workpiece all passes drive part back, the power that one larger is needed during locking, the comparatively special oblique clamping work pieces by clamp shaft of structure clamping structure of the present invention, after clamping, the reaction force of workpiece has major part to directly act on clamp shaft to be delivered on pedestal, fraction passes drive part back, the reaction force that drive part is subject to is less, and workpiece is convenient to clamping, not easily relaxes after piece-holder simultaneously.
Further, drive part is provided with screw thread, and drive unit is swivel head, and swivel head offers screwed hole, and drive part is threaded with swivel head, and upper cover is provided with a stop pin, and clamp shaft is provided with to prolong and axially arranges chute, and stop pin coordinates with chute; Use screw-driven as drive unit, easy realization has self-locking effect simultaneously.
Further, be provided with sleeve in the inclined hole at clamp shaft place, the head end of sleeve is provided with an annular boss, and sleeve tail end end inserts in inclined hole, and annular boss and upper cover are bolted.Inclined hole two ends are all fixed with a sleeve; Direct processing pedestal is not easily processed, and cannot reach requirement on machining accuracy simultaneously, and processing sleeve is easier, and precision is higher.
Further, the screwed hole of swivel head runs through swivel head, and swivel head comprises and revolves head and swing arm, and swing arm and end cap offset, and revolve the regular hexagon that head is nut shape; Regular hexagon more easily screws.

Detailed description of the invention
Spherical fixture by reference to the accompanying drawings shown in 1, comprise bottom base 2, bottom base 2 is provided with standing groove 3, standing groove 3 for place work piece 5 spherical part.
Workpiece 5, main body 51 is that spherical, spherical low side has a base 52.As shown in Figure 1, upper cover 1, upper cover 1 and bottom base 2 are bolted to connection, upper cover 1 is provided with workpiece 5 groove, workpiece 5 groove of upper cover 1 and the standing groove 3 of bottom base 2 form the cavity that can hold workpiece 5, upper cover 1 runs through the clamp shaft 6 having to be obliquely installed, and clamp shaft 6 is divided into clamping part 61 and threaded portion 62, and clamping part 61 is provided with the horizontal seal face 611 coordinated with workpiece 5 base 52 end face.
Clamp shaft 6 and sleeve 4 as shown in Figure 3 and Figure 4, sleeve 4 is provided with in the inclined hole at clamp shaft 6 place, if the object of sleeve 4 is that the difficulty of processing of reduction through hole is high, itself and clamp shaft 6 are closely cooperated and needs very high machining accuracy, processing a sleeve 4 by contrast makes it coordinate can be more prone to clamp shaft 6, in order at inclined hole internal fixtion sleeve 4, is provided with an annular boss 41 in one end of sleeve 4, annular boss 41 is provided with screwed hole 411, and annular boss 41 and upper cover 1 are bolted.Inclined hole two ends are all fixed with a sleeve 4, and the one end not arranging annular boss 41 is inserted in inclined hole by sleeve 4, is fixed by sleeve 4 by annular boss 41.It should be noted that and can leave space between two sleeves 4, space is mated with the horizontal seal face 611 on clamp shaft 6.
Folder lid 1 is provided with the stop pin 7 of a cylindricality, and stop pin 7 runs through sleeve 4 and clamp shaft 6, and coordinate with the chute 612 that clamp shaft 6 is offered, this chute 612 can make clamp shaft 6 slide normally, and the main purpose of stop pin 7 prevents clamp shaft 6 from rotating.
As shown in Figure 2, swivel head 8, end cap 9, swivel head 8 offers screwed hole 82, and the threaded portion 62 of clamp shaft 6 runs through end cap 9 and is threaded with swivel head 8.The head 81 of swivel head 8 is regular hexagon, and be convenient to spanner and the debugging of other instruments, bar portion 83 and the end cap 9 of spiral head 8 are close to, and end cap 9 is close to clamp shaft 6.
During use, it is made to rotate because stop pin 7 locks clamp shaft 6, when there is relative rotation in the clamp shaft 6 that swivel head 8 and its are threaded, clamp shaft 6 can prolong sleeve 4 and be moved, clamp shaft 6 is the upper covers 1 laterally run through, clamp shaft 6 and horizontal plane have 20 ° ~ 35 ° inclinations angle spent, because clamp shaft 6 moving direction and horizontal direction have certain angle of inclination, the effect finally reached is then, be arranged at horizontal seal face 611 on clamp shaft 6 in movement near or away from workpiece 5, time close, clamp shaft 6 is by horizontal seal face 611 clamping work pieces 5, away from time, clamp shaft 6 unclamps workpiece 5.Clamp shaft 6 coordinates standing groove 3 can firm grip workpiece 5.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
