Abstract
A kind of 2 hold down gags, by pressing plate, briquetting, support bar and clamping screw composition, it is characterized in that one end of described pressing plate is a fork ear structure, there is a slotted hole at the middle part of pressing plate, another proximal head place of pressing plate is provided with a connecting through hole, briquetting is a v-shaped structure with two pressure heads, the root of briquetting by hinge on the fork ear structure of briquetting termination, the front end of briquetting two pressure heads is circular arc, clamping screw is connected on the slotted hole in the middle part of pressing plate by nut, support bar is fixed on the connecting through hole at another proximal head place of pressing plate by nut.
Description
Technical field
The utility model relates to during airplane parts is produced the hold down gag used, in particular for 2 hold down gags that dual stage terrace compresses.
Background technology
In the manufacturing of airplane parts, in order to retaining element, ensure machining accuracy, suitable compression mode must be adopted.Airplane parts is numerous and jumbled, and seal face is that the part machinery of monoplane adds man-hour, the flat clamp combination of dimension can be adopted to compress, reach instructions for use.But, for the part compressing dual stage terrace, adopt flat clamp to compress, do not reach the effect of uniform force application.
Summary of the invention
In order to overcome existing double step surface parts, and the plate rib of band angle can not simultaneously 2 compression, and cause hold down gag to exert a force uneven, the purpose of this utility model is to provide a kind of 2 hold down gags that simultaneously can meet the function of 2 compressions.
A kind of 2 hold down gags, by pressing plate, briquetting, support bar and clamping screw composition, it is characterized in that one end of described pressing plate is a fork ear structure, there is a slotted hole at the middle part of pressing plate, another proximal head place of pressing plate is provided with a connecting through hole, briquetting is a v-shaped structure with two pressure heads, the root of briquetting by hinge on the fork ear structure of briquetting termination, the front end of briquetting two pressure heads is circular arc, clamping screw is connected on the slotted hole in the middle part of pressing plate by nut, support bar is fixed on the connecting through hole at another proximal head place of pressing plate by nut.
The beneficial effects of the utility model are, briquetting is hinged on pressing plate, briquetting opposing platen can rotate, two pressure heads of briquetting can be crimped on level by casting die simultaneously, also can be crimped on respectively differing heights by casting die, overcome the drawback that existing hold down gag evenly can not compress the part of dual stage terrace; It is simple that the utility model also has structure, easy to operate advantage.
Below in conjunction with embodiment accompanying drawing, the application is described in further detail:
Accompanying drawing explanation
Fig. 1 is the structural representation of the application
Fig. 2 is that the application compresses co-altitude and illustrated by casting die
Fig. 3 is that the application compresses step and illustrated by casting die
Fig. 4 is that the application compresses inclined-plane and illustrated by casting die
Number description: 1 pressing plate, 2 briquettings, 3 support bars, 4 hold-down bolts, 5 fork ear structures, 6 slotted holes, 7 bearing pins, 8 workpiece, 9 locating holes, 10 are by casting die
Detailed description of the invention
See accompanying drawing, one 2 hold down gags of the application as shown in Figure 1, by pressing plate 1, briquetting 2, support bar 3 and hold-down bolt 4 form, it is characterized in that one end of described pressing plate 1 is a fork ear structure 5, there is a slotted hole 6 at the middle part of pressing plate 1, another proximal head place of pressing plate is provided with a connecting through hole, briquetting 2 is v-shaped structures with two pressure heads, the root of briquetting 2 is hinged on the fork ear structure 5 of briquetting termination by bearing pin 7, the front end of briquetting two pressure heads is circular arc, hold-down bolt 4 is connected on the slotted hole 6 in the middle part of pressing plate by nut, support bar 3 is fixed on the connecting through hole at another proximal head place of pressing plate by nut.
During use, be fixed on the locating hole 9 of workpiece 8 by the hold-down bolt 4 of hold down gag, support bar 3 is supported on the surface of workpiece 8, by casting die 10 be one dull and stereotyped time, as shown in Figure 2, plane is pressed on workpiece 8 by two pressure heads of briquetting 2 by casting die; When being steps by casting die 10, as shown in Figure 3, two pressure heads of briquetting are crimped on different step surfaces respectively; When there being angle by two faces of casting die 10, as shown in Figure 4, two pressure heads of briquetting 2 are crimped on two faces of angle respectively.
