Abstract
The utility model relates to a pressing plate for a machining fixture. The pressing plate comprises an elongated pressing plate body, the middle of the pressing plate body is provided with a through screw groove, the bottom of the pressing plate is provided with a shallow ejector rod groove, the pressing plate body corresponding to a compression end is fittingly provided with a pressure head, and the end face of one end of the pressure head is a compression face which is a cobwebbing face. The pressing plate for the machining fixture is simple in structure and convenient to maintain; by means of spherical cooperation of a pressure head body and a spherical pressure head, automatic angle adjustment of the compression face along with shapes of workpieces can be realized, and accordingly influences of human factors on product quality can be weakened; using the pressing plate can improve integral intrinsic rigidity of dies.
Description
Technical field
The utility model belongs to mechanical processing technique equipment technology field, is specifically related to the pressing plate that machined frock is used.
Background technology
In machining, thin-walled parts processing is a difficult point always, if fastening force is excessive, can cause workpiece deformation, if fastening force is too small, having cannot fully effective fixation workpiece, and in process, workpiece has walks about, and reduces mold integral rigidity.Common fastening workpiece major part all needs to use pressing plate, and by being rotated down nut, pressing plate afterbody push rod maintains static, and the anterior seal face workpiece pressing of pressing plate, completes the needed processing of workpiece.The seal face of existing pressing plate is light face, between the seal face of pressing plate and surface of the work, be that rigidity contacts, for surface of the work out-of-flatness (especially casting workpiece) etc., there is the workpiece to be machined of die cavity, in actual use procedure, easily occur compressing point too concentrated, cause workpiece deformation, affect product quality.
Summary of the invention
The defect existing in order to solve existing pressing plate, the utility model, by architecture advances, provides a kind of pressing plate for machined frock.
Concrete improvement technical scheme is as follows:
The pressing plate body that comprises strip for the pressing plate of machined frock, the middle part of pressing plate body offers the screw slot of perforation, and bottom offers push rod shallow slot along its length; On the pressing plate body corresponding with compressing end, coordinate and be provided with pressure head, the end face of pressure head one end is seal face, and described seal face is reticulate patterned surface; Described pressure head is comprised of pressure head body and spherical indenter; Pressure head body is cylinder, and one end of pressure head body is provided with the spherical blind hole of indent, and the other end is screw rod, and pressure head body is being threaded connection pressing plate body; One end of described spherical indenter is billiard table, and the end face of the other end is seal face; It between the spherical blind hole of pressure head body and the billiard table of spherical indenter, is sphere cooperation; The reticulate patterned surface center of described spherical indenter is provided with the shallow circular trough of indent.
Useful technique effect of the present utility model embodies in the following areas:
1. the utility model is simple in structure, and it is convenient to safeguard; Reduced the requirement to workpiece to be machined type quality;
2. pressure head body and spherical indenter are coordinated and can be realized seal face angle and automatically regulate with workpiece profile by sphere, can reduce the impact of human factor on product quality;
3. use this pressing plate, can improve the integral rigidity of mould own.

Sequence number in upper figure: pressing plate body 1, reticulate patterned surface 2, pressure head body 3, spherical indenter 4, shallow circular trough 5, screw slot 11, push rod 12, double threaded screw 13, push rod shallow slot 14, nut 15, spring 16, workpiece 18, mould 19.
The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
Embodiment
Referring to Fig. 1 and Fig. 2, the pressing plate body 1 that comprises strip for the pressing plate of machined frock, the middle part of pressing plate body 1 offers the screw slot 11 of perforation, and bottom offers push rod shallow slot 14 along its length, on the pressing plate body 1 corresponding with compressing end, coordinates and is provided with pressure head.Referring to Fig. 3 and Fig. 4, pressure head is comprised of pressure head body 3 and spherical indenter 4; Pressure head body 3 is cylinder, and one end of pressure head body 3 is provided with the spherical blind hole of indent, and the other end is screw rod, and pressure head body 3 is being threaded connection pressing plate body 1.One end of spherical indenter 4 is billiard table, and the end face of the other end is seal face, and seal face is reticulate patterned surface 2; In reticulate patterned surface 2 centers, be provided with the shallow circular trough 5 of indent; Between the spherical blind hole of pressure head body 3 and the billiard table of spherical indenter 4, be sphere secure fit, the two forms a concentric spheroid.
Referring to Fig. 5, during use, pressing plate body 1 is fixed on mould 19 by double threaded screw 13 and nut 15, is set with spring 16 on double threaded screw 13; By the cooperation of the push rod shallow slot 14 on push rod 12 and pressing plate body, adjust the position of pressing plate on mould 19; The end face of the reticulate patterned surface of spherical indenter 4 and workpiece 18 is adjacent to.The thin-wall part that workpiece 18 is ring-type.Pressure head body 3 and spherical indenter 4 are coordinated and can be realized seal face angle and automatically regulate with workpiece profile by sphere; The shallow circular trough structure at reticulate patterned surface 2 middle parts of profile of tooth, can avoid workpiece blank in toothed surface center projection, and build-up of pressure is concentrated, and increases stress point spacing, prevents workpiece 18 distortion.
