Abstract
The invention relates to a use method for a perforation locating clamp. The use method comprises the following steps that first, an arc face on a workpiece makes contact with an arc face on a locating plate, and it is guaranteed that the side wall and the bottom of the workpiece both make contact with locating pins; second, a bolt is sleeved with a pressing block which is made to be aligned with a round hole in the workpiece, and the workpiece is fixedly pressed on the side wall of the locating plate; third, drilling is carried out on the arc face of the workpiece to form inclined holes; fourth, the locating plate is made to rotate by a certain angle, and then two inclined holes are drilled. The perforation locating clamp is simple in structure, convenient to operate, and high in locating and machining precision.
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 cambered surface workpiece rat holing.
Background technology
Workpiece 1 as depicted in figs. 1 and 2, it has on two arc surfaces 11 and arc surface 13 and sidewall thereof and has a circular hole 14, need to get through hole 12 on arc surface 13, because arc surface 11 and arc surface 13 all have certain radian, when carrying out clamping to it and fixing, can not be there is mutual movement in arc surface 11 and frock, ensure the machining accuracy of through hole 12.
Summary of the invention
The present invention is directed to the problems referred to above of the prior art, provide a kind of using method of the positioning fixture that punches, 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:
The using method of punching positioning fixture, comprises the steps:
The first step, contacts the arc surface on workpiece with the arc surface on location-plate, ensures that the sidewall of workpiece and bottom all contact with alignment pin;
Second step, is enclosed within briquetting on bolt, and makes briquetting align circular hole on workpiece, is fixed and clamped by workpiece on the sidewall of location-plate;
3rd step, the arc surface on workpiece carries out Drilling operation, gets inclined hole;
4th step, makes the rotation of location-plate generation certain angle, gets out two inclined holes respectively.
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.
Accompanying drawing explanation
Fig. 1 and Fig. 2 is the stereogram of workpiece.
Fig. 3 is using state figure of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 to Figure 3, the present invention includes location-plate 2 and briquetting 4, the top of the sidewall 23 of location-plate 2 is provided with locating dowel 3, and locating dowel 3 is three, and one of them is positioned at the side-walls of workpiece 1, and two bottoms being positioned at workpiece 1, for supporting and location workpiece 1; The radian of the cambered surface 22 on location-plate 2 is identical with the radian of the arc surface 11 on workpiece 1, the accurate location of cambered surface 22 pairs of workpiece 1; The excircle dimension of briquetting 4 is greater than the size of circular hole 14 on workpiece 1; Workpiece 1 is fixed on location-plate 2 by bolt 5 by briquetting 4; With locating hole 21 on the sidewall 23 of location-plate 2, location-plate 2 and the positioner on equipment can be fixed;
Use method of operating of the present invention is as follows:
The first step, contacts the arc surface 11 on workpiece 1 with the arc surface 22 on location-plate 2, ensures that the sidewall of workpiece 1 and bottom all contact with alignment pin 3;
Second step, is enclosed within briquetting 4 on bolt 5, and makes briquetting 4 align circular hole 14 on workpiece 1, is fixed and clamped by workpiece 1 on the sidewall 23 of location-plate 2;
3rd step, the arc surface 13 on workpiece 1 carries out Drilling operation, gets inclined hole 12;
4th step, makes the rotation of location-plate generation certain angle, gets out two inclined holes 12 respectively.
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.
