Description

A kind of flexible fixture
Technical field
This utility model relates to field of machining, especially a kind of fixture.
Background technology
Along with the fast development of mechanical industry, require also to be greatly improved to part processing precision.Fixture is can Make the process unit that product is accurately positioned by certain technology requirement and firmly clamps.For guaranteeing different workpieces Machining accuracy, the design and use of fixture also function to vital effect.Lathe many employings plane pincers at present Formula fixture, plane jaw type fixture is primarily adapted for use in the fixing of square and that hardness is higher blank.When using plane When the tight arc of clamp and the relatively low blank of hardness, blank will necessarily be made to produce elastic deformation, but machining, When shedding clamping force, blank recovers elastic deformation, so that machining accuracy reduces.
Summary of the invention
This utility model purpose is to provide a kind of curved surfaces rational in infrastructure, with low cost, applicable and hardness The flexible fixture of relatively low blank.
For achieving the above object, have employed techniques below scheme: this utility model mainly include two identical Dop and two regulation bolts, described dop is made up of lower cover, two pieces of side panels, riser and cell cube; The symmetrical affixed side panel in the left and right sides on lower cover surface, the affixed one piece of riser of outer side-stand type at lower cover; Described riser Surface Machining multiple rows of screwed hole A;In the screwed hole A of riser, threaded cell cube, described Cell cube is made up of the rectangular body of rod and threaded rod, and spherical structure, body of rod tail end are processed in the front end of the rectangular body of rod Processing thread groove is also connected with the nose threads of threaded rod, the tail end of threaded rod insert riser screwed hole A and Riser is threaded;End face at side panel laterally offers screwed hole B;Two dops are symmetrical structure, at card It is attached by regulation bolt between the side panel screwed hole B of head homonymy.
Further, the end face at side panel the most longitudinally offers screwed hole C, upper at lower cover and side panel Side is provided with upper cover plate, and described upper cover plate is pressed in the end face of two pieces of side panels, and fixing bolt inserts through upper cover plate Upper cover plate is linked together by the screwed hole C of side panel with side panel.
Further, at the surface of riser another processing mounting holes A, outside riser, be provided with outside plate, described outside Plate is provided with screwed hole D and installing hole D, and screwed hole D, installing hole D and the screwed hole A on riser, Installing hole location A is corresponding, and outside plate threadeds fastening spiral shell with riser in the installing hole of two boards body after being close to Both are connected fixing by bolt.
Further, described side panel is L-shaped right angle side panel, and vertical section plate body is fixed in side panel surfaces Side, the side of vertical section plate body flushes with side panel side, and horizontal segment plate body is outside from the side of side panel Lean out, horizontal segment plate body is laterally offered screwed hole B.
Work process approximately as:
After blank is positioned over the center of fixture, then by regulation bolt, two dops are adjusted to correct position, Rotate the cell cube threaded rod in each screwed hole of riser, make the front end sphere of each unit body all contact also with blank Compressing, blank is fixed by each unit body, the most just can carry out next processor.After processing, operator Member only need to loosen regulation bolt, just can take out blank from clamp central region, and the position of each unit body can be protected Hold inconvenience, it is not necessary to the position of cell cube is all adjusted, if the precision of each blank is slightly by processing every time Difference, operator only certain several cell cube need to be carried out positioning fixing just can, effectively save the working time, Improve work efficiency.
Compared with prior art, this utility model has the advantage that
1, each cell cube position of fixture all can independent regulation, after cell cube position adjustments, discrete by these Cell cube front end sphere constitute discrete enveloping surface, be particularly suitable for the clamping of curved surface blank.
Only need to change the position of two dops when 2, changing blank, and be not required to cell cube is operated.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
As shown in Figure 1, 2, 3, this utility model mainly includes two identical dops and two regulation spiral shells Bolt 1, described dop is made up of 2, two pieces of side panels 3 of lower cover, riser 4 and cell cube 5;At lower cover The symmetrical affixed side panel in the left and right sides on surface, the affixed one piece of riser of outer side-stand type at lower cover;Described vertical Plate Surface Machining multiple rows of screwed hole A6;Threaded cell cube in the screwed hole A of riser, described cell cube Being made up of the rectangular body of rod and threaded rod, spherical structure, body of rod tail end processing spiral shell are processed in the front end of the rectangular body of rod Groove is also connected with the nose threads of threaded rod, and the tail end of threaded rod inserts screwed hole A and the riser spiral shell of riser Stricture of vagina connects;End face at side panel laterally offers screwed hole B8;Two dops are symmetrical structure, same at dop It is attached by regulation bolt between the side panel screwed hole B of side.
End face at side panel the most longitudinally offers screwed hole C9, being arranged over of lower cover and side panel Cover plate 10, described upper cover plate is pressed in the end face of two pieces of side panels, and fixing bolt 11 inserts side through upper cover plate Upper cover plate is linked together by the screwed hole C of plate with side panel.
At the surface of riser another processing mounting holes A7, being provided with outside plate 12 outside riser, described outside plate is provided with Screwed hole A on screwed hole D13 and installing hole D14, and screwed hole D, installing hole D and riser, installation Hole location A is corresponding, and outside plate threadeds fastening bolt 15 with riser in the installing hole of two boards body after being close to Both are connected fixing.The motion of the threaded rod of cell cube on riser is limited by outside plate.
Described side panel is L-shaped right angle side panel, and vertical section plate body is fixed in side panel surfaces side, vertically The side of section plate body flushes with side panel side, and horizontal segment plate body outwards leans out from the side of side panel, at water Screwed hole B is laterally offered on flat section plate body.
Wherein, cell cube is fettered vertical direction by upper and lower cover plate, by two side panel constraint left and right horizontal sides To, the size of each unit body is identical
Embodiment described above is only to be described preferred implementation of the present utility model, the most right Scope of the present utility model is defined, on the premise of without departing from this utility model design spirit, and this area Various deformation that the technical solution of the utility model is made by those of ordinary skill and improvement, all should fall into this reality In the protection domain determined with novel claims.
