Abstract

The utility model belongs to frock clamp provides a control PARTS DEFORMED fixture, can improve effective cutting time proportion greatly, guarantees processingquality to reach the final mesh that improves numerical control machining efficiency. Technical scheme includes: the symmetry sets up 1, 2 adjustable 2, 2 locating pin 3 of clamp plate of separating of 2 clamp plates on base, the base, the part blank is placed on the base, and 2 clamp plates 1 compress tightly the part blank from tops, and 2 adjustable separates clamp plate 2 respectively from the tight part blank in both sides top, and the via hole that 2 locating pins 3 passed part blank spiro union is on the base.

Description

Control part deformation fixture

Technical field

The invention belongs to frock clamp, relate to a kind of control part deformation fixture。

Background technology

Certain type part is important parts, and element precision requires higher, carries out timeliness and uses frock to process part after adopting roughing；But owing to part is more complicated, yielding, processing and loading clamp is interfered, therefore need to readjust clamp fixture, it is subjected to displacement under the effect of cutting force in order to the workpiece that makes to have good positioning is unlikely so that it is remain correct position in the course of processing, also need to clip Work-sheet pressing。

Summary of the invention

The purpose of the present invention: propose one and control part deformation fixture, can be greatly improved effective cutting time ratio, it is ensured that crudy, thus reaching to improve the final purpose of efficiency of numerical control (NC) machining。

Technical scheme: a kind of control part deformation fixture, including:

Pedestal, pedestal are symmetrical arranged 2 pressing plates 1,2,2,2 alignment pins 3 of adjustable solution pressing plate；

Part blank is placed on pedestal, and 2 pressing plates 1 are from top compressing component blank, and 2 adjustable solution pressing plates 2 hold out against part blank from both sides respectively, and the via that 2 alignment pins 3 are spirally connected through part blank is on pedestal。

Advantages of the present invention: frock is simple and reliable, easy to operate, fixture positions well, and clamping point is reasonable, meets processing request。

Accompanying drawing illustrates:

Fig. 1 is present configuration schematic diagram。

Fig. 2 is that the present invention is installed schematic diagram。

Detailed description of the invention:

Below in conjunction with accompanying drawing, the present invention is described in further detail。

One of the present invention controls part deformation fixture, as shown in Figure 1, 2, and including:

Pedestal, pedestal are symmetrical arranged 2 pressing plates (1), 2 adjustable solution pressing plates (2), 2 alignment pins (3)；

Part blank is placed on pedestal, and 2 pressing plates (1) are from top compressing component blank, and 2 adjustable solution pressing plates (2) hold out against part blank from both sides respectively, and the via that 2 alignment pins (3) are spirally connected through part blank is on pedestal。

Tool structure adopts pressing plate fastening, the mode of pin location, can also adopt and adjustment packing ring is set between platen element and parts, adjust the strong point etc. and control part deformation size, compensate the error of other element, improve the precision (shown in Fig. 1) of fixture。

Part both sides, by increasing work platen support point after polish, control stud deflection, play support positioning action, make the residual stress in part be in poised state (shown in Fig. 2)。

Claims (1)

1. one kind controls part deformation fixture, it is characterised in that including:

Pedestal, pedestal are symmetrical arranged 2 pressing plates (1), 2 adjustable solution pressing plates (2), 2 alignment pins (3)；

Part blank is placed on pedestal, and 2 pressing plates (1) are from top compressing component blank, and 2 adjustable solution pressing plates (2) hold out against part blank from both sides respectively, and the via that 2 alignment pins (3) are spirally connected through part blank is on pedestal。
