Abstract

The utility model relates to a multifunction milling locating tool, comprising an upper die and a lower die, wherein a through hole is formed in the upper die; screw holes and positioning holes are respectively formed in two sides of the through hole; a blanking hole is formed in the lower die; locating pins, limiting posts and fixing holes are arranged on two sides of the blanking hole; a step is also arranged on the lower die; an arc-shaped corner is arranged on the side wall of the step; U-shaped grooves are formed in two sides of the lower die. The multifunction milling locating tool has the advantages that the structure is simple, the use is flexible and convenient, the clamping is simple, and the processing precision is high.

Description

Multi-functional milling positioning tool

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to the positioner that can simultaneously carry out multistation processing to same workpiece.

Background technology

Workpiece 1 as described in Figure 1, it is tabular, now need processing arcuate socket 11 and arc chord angle 12 on it, conventional milling processing technology is carried out multistation processing for needs simultaneously, often needs how secondary frock clamp, respectively workpiece is processed, so have a strong impact on working (machining) efficiency, simultaneously also because of the change of positioning datum, cause the machining accuracy of workpiece not meet the demands.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of multi-functional milling positioning tool, and it is simple in structure, flexible and convenient to use, and machining accuracy is high.

The technical scheme that the utility model adopts is as follows:

Multi-functional milling positioning tool, comprises upper die and lower die, on patrix, with through hole, is positioned at the both sides of through hole respectively with screw hole and locating hole; On counterdie, with material-dropping hole, be positioned at material-dropping hole both sides with alignment pin, limited post and fixing hole; On counterdie, also with step, the side-walls of step is with arc corners, and the both sides of counterdie are with U-lag.

The utility model has the advantage of: be divided into upper die and lower die, and the patrix setting through hole identical with arcuate socket shape on institute processing work, the correspondence position of counterdie arranges material-dropping hole, between upper and lower mould, pass through alignment pin, position fixing with screw, workpiece is undertaken spacing by limited post on counterdie, on counterdie, arrange and be exclusively used in the step that workpiece is carried out to milling arc chord angle simultaneously, so can realize after hole milling, directly carry out the processing of milling arc chord angle, need not carry out again clamping location to workpiece, simple in structure, flexible and convenient to use, machining accuracy and efficiency easily guarantee.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figures 1 to 4, the utility model comprises patrix 2, counterdie 3, on patrix 2 with through hole 22, the geomery of through hole 22 is identical with the circular hole 11 on workpiece 1, add man-hour, milling cutter, along the inner circle walking of through hole 22, is positioned at the both sides of through hole 22 respectively with screw hole 23 and locating hole 21 on patrix 2, screw hole 23 is fixed on counterdie 3 for mounting screw by patrix 2, and locating hole 21 is for locating the relative position of patrix 2 and counterdie 3; On counterdie 3 with material-dropping hole 32, add man-hour, the waste material of workpiece 1 can drop in material-dropping hole 32, also can prevent that milling cutter from contacting with counterdie 3, be positioned at material-dropping hole 32 both sides with alignment pin 31, limited post 33 and fixing hole 34, alignment pin 31 coordinates with the locating hole 21 on patrix 2, spacing for to workpiece 1 of limited post 33, can there is not deviation in the position that guarantees workpiece 1, the screw of fixing counterdie 2 and counterdie 3 is finally contained in fixing hole 34; On counterdie 3 also with step 35, the side-walls of step 35 is with arc corners 36, the Angular Dimension of arc corners 36 is identical with the arc chord angle 12 on workpiece 1, add man-hour, milling cutter is along arc corners 36 feeds, can process the arc chord angle 12 on workpiece 1, because workpiece 1 does not need to reorientate, the position degree of the arcuate socket 11 of the arc chord angle 12 on workpiece 1, and the machining accuracy of itself easily guarantees, and working (machining) efficiency is also higher, the both sides of counterdie 3, with U-lag 37, are conveniently fixed on counterdie 3 on operating desk;

Using method of the present utility model is as follows:

The first step, is first fixed to counterdie 3 on operating desk;

Second step, is placed in workpiece 1 between limited post 33, and makes the parallel sidewalls of end face and the step 35 of workpiece 1;

The 3rd step is placed patrix 2 on workpiece 1, and the alignment pin 31 on counterdie 3 is inserted in the locating hole 21 of patrix 2;

The 4th step, is used screw by fixing hole 23, patrix 2 and counterdie 3 to be fixed on firmly;

The 5th step, carries out milling process operation to workpiece 1.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
