Abstract
The utility model relates to a cambered surface inclined hole positioning tool. The cambered surface inclined hole positioning tool comprises a positioning plate and a pressing block; a positioning column is mounted at the top of a side wall of the positioning plate; the radian of a cambered surface on the positioning plate is the same as that of a circular-arc-shaped surface on a workpiece; the size of the outer circle of the pressing block is greater than the size of a circular hole in the workpiece; and the pressing block is used for fixing the workpiece on the positioning plate through a bolt. The cambered surface inclined hole positioning tool disclosed by the utility model is simple in structure, is simple and convenient to operate, and has high positioning and machining precision.
Description
Technical field
The utility model relates to technical field of tooling clamps, relates in particular to a kind of positioning fixture for precise thin cambered surface workpiece rat holing is used.
Background technology
Workpiece 1 as depicted in figs. 1 and 2, it has a circular hole 14 is arranged on two arc surfaces 11 and arc surface 13 and sidewall thereof, need to get through hole 12 on arc surface 13, because arc surface 11 and arc surface 13 all have certain radian, it is being carried out clamping fixedly the time, mutual movement can not occur with frock in arc surface 11, guarantees the machining accuracy of through hole 12.
The utility model content
The utility model provides a kind of cambered surface to beat the inclined hole positioning tool for the problems referred to above of the prior art, and it is simple in structure, and is easy and simple to handle, and the location machining accuracy is high.
The technical scheme that the utility model adopts is as follows:
Cambered surface is beaten the inclined hole positioning tool, comprises location-plate and briquetting, and the top of the sidewall of location-plate is equipped with locating dowel, and the radian of the arc surface on the radian of the cambered surface on location-plate and workpiece is identical; The excircle dimension of briquetting is greater than the size of circular hole on workpiece; Briquetting is fixed on workpiece on location-plate by bolt;
Further technical scheme is as follows:
Locating dowel on described location-plate is three, and one of them is positioned at the side-walls of workpiece, two bottoms that are positioned at workpiece;
The sidewall of described location-plate is with locating hole.
The utility model has the advantage of: arrange on pedestal need to punching place with workpiece the consistent cambered surface of cambered surface, the while arranges alignment pin in the bottom of cambered surface, and workpiece is positioned; The inclined-plane also is set on pedestal, with locating hole, by bolt, workpiece is positioned on the inclined-plane, the position of workpiece is fixed; Cambered surface on pedestal and inclined-plane are symmetrical arranged, by twice clamping, can process two inclined holes on the workpiece cambered surface; The utility model is simple in structure, and is easy and simple to handle, and the location machining accuracy is high.
Description of drawings
Fig. 1 and Fig. 2 are the stereogram of workpiece.
Fig. 3 is use state diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1 to Figure 3, the utility model comprises location-plate 2 and briquetting 4, and the top of the sidewall 23 of location-plate 2 is equipped 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 that are positioned at workpiece 1 are used for supporting and location workpiece 1; The radian of the arc surface 11 on the radian of the cambered surface 22 on location-plate 2 and workpiece 1 is identical, the accurate location of 22 pairs of workpiece 1 of cambered surface; The excircle dimension of briquetting 4 is greater than the size of circular hole 14 on workpiece 1; Briquetting 4 is fixed on workpiece 1 on location-plate 2 by bolt 5; With locating hole 21, location-plate 2 and the positioner on equipment can be fixed on the sidewall 23 of location-plate 2;
Use method of operating of the present utility model is as follows:
The first step contacts the arc surface 11 on workpiece 1 with arc surface 22 on location-plate 2, guarantee that sidewall and the bottom of workpiece 1 all contacts 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, and workpiece 1 is fixed and clamped on the sidewall 23 of location-plate 2;
The 3rd step, carry out Drilling operation on the arc surface 13 on workpiece 1, get inclined hole 12;
The 4th step made the rotation of location-plate generation certain angle, got out respectively two inclined holes 12.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
