Description
Technical field:
The utility model relates to mechanical field, relates in particular to frock clamp, particularly a kind of film chuck.
Background technology:
Often need the processing disk-like accessory in the machine-building.The processing of disk-like accessory needs just can finish through multiple working procedure.In order to guarantee row position tolerance, to manufacture and design a plurality of frocks between each operation, expended a large amount of manpower and materials, increased manufacturing cost.In the prior art, the frock that the disk-like accessory inter process is adopted is scroll chuck or special tooling.But the scroll chuck positioning accuracy is low, only is used in the roughing operation; Though the special tooling precision is higher, versatility is poor, and the production preparatory period is long, the manufacturing cost height.
Summary of the invention:
The purpose of this utility model provides a kind of film chuck, and the positioning fixture frock precision that described this film chuck will solve processing disk-like accessory in the prior art is low, the technical problem of versatility difference.
This film chuck of the present utility model is made of a plate-like revolving body, wherein, be provided with axis hole in the end face of one end of described plate-like revolving body, the other end of plate-like revolving body is connected with an elastic card claw dish, the central axes of described elastic card claw dish and plate-like revolving body, elastic card claw rim axis direction is provided with one and connects end face and a claw end face, the periphery of described connection end face is fixedlyed connected with the end face of plate-like revolving body by bolt, described claw end face is provided with positioning spigot, described positioning spigot is cylindric or coniform, connect between end face and the plate-like revolving body and be provided with cavity around the axle line therein, the place, axle center that connects end face is provided with screw, be provided with a stretching screw in the described screw, the front end of described stretching screw extends in the cavity between elastic card claw dish and the plate-like revolving body, its excircle of elastic card claw dish upper edge is provided with groove, is provided with 3 gap at least along radial direction in the claw end face.
Further, the central angle between arbitrarily adjacent two described gap equates.
Further, described gap quantity is 4.
Further, the lateral vertical of described axis hole axially is provided with pin in it.
Operation principle of the present utility model is: plate-like workpiece cover to be processed is received on the positioning spigot of elastic card claw dish, rotate the stretching screw with spanner, because stretching screw front end contacts with plate-like revolving body end face and can't move inwards, just force the elastic card claw dish to produce strain, make the positioning spigot external diameter become big, thereby realize the clamping of workpiece.Rotate the stretching screw in the opposite direction, elastic card claw returns to the original form, and just can unload workpiece.The size of clamping force is decided by the rigidity of elastic card claw and the size of deflection, and the size of deflection is decided by the amount of tightening of stretching screw.The thickness that increases elastic card claw can improve its rigidity, can determine the thickness of elastic card claw according to the size of the size of part and cutting force.The axis hole of the end by the plate-like revolving body can be connected to the plate-like revolving body on the main shaft of lathe.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is arranged at elastic card claw and helicitic texture in the chuck, by screw the elastic card claw distortion is realized the fastening of workpiece and location, and is convenient to use, shortened non-cutting time, improved production efficiency; The versatility of film chuck is good, has reduced the design of frock and has made quantity, has reduced production cost of products; Simultaneously, because the contact area of the claw of film chuck and workpiece is big, makes part not yielding, thereby improved the crudy of part.
Description of drawings:
Fig. 1 is the structural representation of film chuck of the present utility model.
Fig. 2 is the course of work schematic diagram of film chuck of the present utility model.
The specific embodiment:
As depicted in figs. 1 and 2, film chuck of the present utility model is made of a plate-like revolving body 1, wherein, be provided with axis hole 10 in the end face of one end of described plate-like revolving body 1, the other end of plate-like revolving body 1 is connected with an elastic card claw dish 2, the central axes of described elastic card claw dish 2 and plate-like revolving body 1, elastic card claw dish 2 is provided with one along axis direction and connects end face 4 and a claw end face, the periphery of described connection end face 4 is fixedlyed connected with the end face of plate-like revolving body 1 by bolt 9, described claw end face is provided with positioning spigot 5, described positioning spigot 5 is cylindric or coniform, connect between end face 4 and the plate-like revolving body 1 and be provided with cavity 6 around the axle line therein, the place, axle center that connects end face 4 is provided with screw, be provided with a stretching screw 7 in the described screw, the front end of described stretching screw 7 extends in the cavity 6 between elastic card claw dish 2 and the plate-like revolving body 1, its excircle of elastic card claw dish 2 upper edges is provided with groove 3, is provided with 3 gap (not drawing among the figure) at least along radial direction in the claw end face.
Further, the central angle between arbitrarily adjacent two described gap equates.
Further, described gap quantity is 4.
Further, the lateral vertical of described axis hole 10 axially is provided with pin (not drawing among the figure) in it.
