Description

A kind of flexible fixture
Technical field
The present invention relates to field of machining, especially a kind of fixture.
Background technology
With the fast development of mechanical industry, part processing precision requirement is also greatly improved.Fixture is can to make product The process unit for being accurately positioned by certain technical requirements and firmly clamping.To ensure the machining accuracy of different workpieces, fixture Design and use also function to vital effect.Lathe uses plane jaw type fixture more at present, and plane jaw type fixture is mainly fitted For the square and higher blank of hardness fixation., will necessarily when using the tight arc of plane clamp and hardness relatively low blank Blank is produced elastic deformation, but machining, when shedding clamping force, blank recovers elastic deformation, so that machining accuracy Reduce.
The content of the invention
Present invention aims at provide it is a kind of it is rational in infrastructure, cost is cheap, is adapted to curved surfaces and the relatively low blank of hardness Flexible fixture.
To achieve the above object, following technical scheme is employed:The invention mainly comprises two identical dops and two Root regulating bolt, the dop are made up of lower cover, two pieces of side panels, riser and cell cube;In the left and right two of lower cover plate surface The symmetrical affixed side panel in side, in the affixed one piece of riser of the outer side-stand type of lower cover;The multiple rows of screwed hole A of riser Surface Machining; Cell cube is threadedly coupled in the screwed hole A of riser, the cell cube is made up of the rectangular body of rod and threaded rod, before the rectangular body of rod Spherical structure is processed at end, and body of rod tail end processing thread groove is simultaneously connected with the nose threads of threaded rod, the tail end insertion of threaded rod The screwed hole A of riser is threadedly coupled with riser;Screwed hole B is laterally opened up in the end face of side panel;Two dops are symmetrical structure, It is attached between the side panel screwed hole B of dop homonymy by regulating bolt.
Further, screwed hole C is longitudinally opened up downwards in the top surface of side panel, be provided with the top of lower cover and side panel Upper cover plate, the upper cover plate are pressed in the top surface of two pieces of side panels, and fixing bolt is inserted through upper cover plate in the screwed hole C of side panel Upper cover plate and side panel are linked together.
Further, in the another processing mounting holes A in the surface of riser, outside plate is provided with the outside of riser, the outside plate is provided with Screwed hole D and mounting hole D, and screwed hole D, mounting hole D are corresponding with the screwed hole A on riser, mounting hole location A, outside plate is with standing Plate is threadedly coupled fastening bolt in the mounting hole of two boards body after being close to and both is connected.
Further, the side panel is L-shaped right angle side panel, and vertical section plate body is fixed in side panel surfaces side, is erected The side of straight section plate body is flushed with side panel side, and horizontal segment plate body is outwards leant out from the side of side panel, in horizontal segment plate body Upper transverse direction opens up screwed hole B.
The course of work approximately as:
After blank is positioned over into the center of fixture, then two dops are adjusted to by correct position by regulating bolt, rotated Cell cube threaded rod in each screwed hole of riser, the front end sphere of each unit body is set to contact and compress with blank, each unit body Blank is fixed, can now carry out next procedure.After processing, operating personnel need to only loosen regulating bolt, Bian Kecong Blank is taken out in clamp central region, and the position of each unit body can keep inconvenience, it is not necessary to which processing is all to the position of cell cube every time It is adjusted, if the precision of each blank is slightly different, it is fixed just that operating personnel need to only carry out positioning to certain several cell cube Can, the working time is effectively saved, improves operating efficiency.
Compared with prior art, the invention has the advantages that:
1st, each unit body position of fixture can be separately adjustable, after cell cube position adjustments, by these discrete units The sphere of body front end forms discrete enveloping surface, is particularly suitable for the clamping of curved surface blank.
It need to only change the position of two dops when the 2nd, changing blank, and be not required to operate cell cube.
