Abstract
The invention relates to a thin-wall cambered-surface positioning tool for inclined hole punching. The thin-wall cambered-surface positioning tool comprises a positioning base provided with a cambered surface, wherein radian of the cambered surface is identical to radian of a cambered surface on a workpiece. A positioning pin is installed at the bottom of the cambered surface. The base is provided with inclined planes, the bottoms of the inclined planes are provided with bosses, the inclined planes are symmetrical relative to the bosses, and positioning holes are arranged on the inclined planes. The thin-wall cambered-surface positioning tool for inclined hole punching is simple in structure, simple and convenient to operate and high in positioning and processing accuracy.
Description
Technical field
The present invention relates to technical field of tooling clamps, particularly relate to a kind of for the positioning fixture to precise thin Workpiece boring.
Background technology
Finished parts 2 as shown in Figure 2, shown in Fig. 1 is the blank 1 of finished parts 2, blank 1 there is cambered surface 11, cambered surface 11 has through hole 12, need to get out at through hole 12 place the counterbore 22 of a finished parts 2 as shown in Figure 2 as requested, accurately must locate cambered surface 11, in order to avoid blank 1 is located inaccurate, affect the machining accuracy of counterbore 22.
Summary of the invention
The present invention is directed to the problems referred to above of the prior art, provide a kind of thin-walled cambered surface to beat inclined hole positioning tool, its structure is simple, easy and simple to handle, and location machining accuracy is high.
The technical solution adopted in the present invention is as follows:
Thin-walled cambered surface beats inclined hole positioning tool, comprises positioning pedestal, and with arc surface on pedestal, the radian of arc surface is identical with the radian of arc surface on workpiece; In the bottom of arc surface, alignment pin is installed; With inclined-plane on pedestal, the bottom on inclined-plane is with boss, and inclined-plane is symmetrical about boss, with locating hole on inclined-plane;
Further technical scheme is as follows:
The two side of described pedestal is all with square groove;
In described locating hole, construction bolt positions workpiece.
The invention has the advantages that: the cambered surface needing the cambered surface of punching place consistent with workpiece is set on pedestal, alignment pin is set in the bottom of cambered surface simultaneously, workpiece is positioned; Pedestal also arranges inclined-plane, with locating hole on inclined-plane, by bolt, workpiece is positioned, the position of workpiece is fixed; Cambered surface on pedestal and inclined-plane are symmetrical arranged, by twice clamping, can process the inclined hole of two in workpiece cambered surface; Structure of the present invention is simple, easy and simple to handle, and location machining accuracy is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figures 1 to 5, the present invention includes positioning pedestal 3, with arc surface 31 on pedestal 3, the radian of arc surface 31 is identical with the radian of arc surface 11 on blank 1, is conducive to positioning the cambered surface 11 of blank 1, prevents the distortion of cambered surface 11; Be provided with alignment pin 32 in the bottom of arc surface 31, the through hole 12 on blank 1 located by alignment pin 32; With inclined-plane 33 on pedestal 3, the bottom on inclined-plane 33 is with boss 35, inclined-plane 33 is symmetrical about boss 35, with locating hole 34 on inclined-plane 33, be provided with bolt 4 in locating hole 34, the end of bolt 4 is pressed in the cambered surface 11 of blank 1, and blank 1 is accurately located, any movement can not be there is, ensure the precision of counterbore 21 on finished parts 2; The both sides of pedestal 3, with square groove 36, can be used for pedestal 3 to be positioned on operating desk;
Use method of operating of the present invention is as follows:
The first step, contacts the back side of the arc surface 11 on blank 1 with the arc surface 31 on pedestal 3, is through on alignment pin 32 by through hole 12 on blank 1 simultaneously;
Second step, inserts bolt 4 in locating hole 34, and on the arc surface 11 that the head of bolt 4 is pressed on blank 1, screwing bolts 4;
3rd step, holes to through hole 12 place on blank 1, processes counterbore 21;
4th step, because the arc surface 31 on pedestal is symmetrical about boss 35 with inclined-plane 33, after processing first counterbore 21, by blank 1 clamping at opposite side, can carry out the processing of second counterbore 21 to it.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
