Description
Technical Field
The utility model relates to a processing frock field, concretely relates to thin wall casing part drilling frock.
Background
The aerospace part is often provided with some special parts, such as thin-wall shell parts, the cross section of each thin-wall shell part is parallelogram, the side wall of each thin-wall shell part is provided with a plurality of holes for heat dissipation or connection, and the inner wall of the shell, which is not provided with the holes, is provided with vertical rib plates. When the holes are machined on the side walls of the parts, the holes are generally machined on semi-finished thin-wall shell parts, and the semi-finished thin-wall shell parts are difficult to effectively clamp and fix by adopting the conventional clamp during drilling, so that the machining efficiency is low and the rejection rate is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a thin wall casing part drilling frock that yield is high, machining efficiency is high.
In order to achieve the above object, the utility model discloses a thin wall casing part drilling frock adopts following technical scheme: the utility model provides a thin wall casing part drilling frock, the on-line screen storage device comprises a base, be provided with the boss that supplies the identical installation of inner wall of semi-manufactured goods thin wall casing part on the base, the cross section of boss is parallelogram, be provided with the mounting groove that supplies the identical installation of vertical gusset of semi-manufactured goods thin wall casing part inner wall on two relative lateral walls of boss respectively, be provided with a plurality of preformed holes that correspond with the position of waiting to process the hole on other two relative lateral walls of boss, still be provided with the compact structure who is used for fixed semi-manufactured goods thin wall casing part on the base.
The pressing structure comprises a pressing plate connected onto the base through a first bolt, and the pressing plate is provided with a pressing surface parallel to the side wall of the boss provided with the mounting groove.
And the pressing plate is provided with a long hole with the length extending along the direction vertical to the pressing surface.
The base is provided with a bolt hole, the boss is provided with a connecting hole corresponding to the bolt hole, and a second bolt penetrates through the connecting hole to realize the detachable connection between the boss and the base.
The base includes the cylinder body, and the one end of cylinder body is provided with the spliced pole, and the other end of cylinder body is provided with the installation reference platform, the boss sets up on the installation reference platform.
The utility model has the advantages that: when the semi-finished product thin-wall shell part fixing device is used, the semi-finished product thin-wall shell part is positioned and installed on the boss by means of the boss and the inner cavity wall of the semi-finished product thin-wall shell part and by means of the installation groove and the vertical rib plates on the inner wall of the semi-finished product thin-wall shell part, and the semi-finished product thin-wall shell part is pressed and fixed by the pressing device. The drilling tool can accurately position a part to be machined, is firm in positioning, ensures high yield in the subsequent machining process, and improves machining efficiency.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of a thin-walled shell part drilling tool according to the present invention;
fig. 2 is a schematic structural diagram ii of an embodiment of the thin-wall casing part drilling tool of the present invention.
Detailed Description
The utility model discloses an embodiment of thin wall casing part drilling frock, as shown in fig. 1-2, including base 1, be provided with the boss 2 that supplies the identical installation of semi-manufactured goods thin wall casing part's inner wall on the base 1, the cross section of boss 2 is parallelogram. Two opposite side walls of the boss 2 are respectively provided with mounting grooves 3 for the vertical rib plates of the inner wall of the semi-finished product thin-wall shell part to be mounted in an inosculation manner, and the number of the mounting grooves 3 is 2. A plurality of preformed holes 7 corresponding to the positions of the holes to be processed are arranged on other two opposite side walls of the boss 2, and a compression structure for fixing semi-finished thin-walled shell parts is further arranged on the base 1. The pressing structure comprises a pressing plate 4 connected to the base through a first bolt 5, and the pressing plate 4 is provided with a pressing surface 12 parallel to the side wall of the boss provided with the mounting groove. And a long hole 6 with the length extending along the direction vertical to the pressing surface is arranged on the pressing plate 4, so that the gap between the pressing plate and the semi-finished thin-walled shell part can be conveniently adjusted. Be provided with the bolt hole on the base 1, correspond with the bolt hole on the boss 2 and be provided with connecting hole 8, wear to be equipped with the second bolt in the connecting hole 8 and realize the releasable connection between boss and the base. The base 1 comprises a cylindrical body 9, a connecting column 10 is arranged at one end of the cylindrical body 9, an installation reference table 11 is arranged at the other end of the cylindrical body 9, and the boss 2 is arranged on the table top of the installation reference table 11.
When the semi-finished product thin-wall shell part fixing device is used, the semi-finished product thin-wall shell part is positioned and installed on the boss, the boss and the inner cavity wall of the semi-finished product thin-wall shell part are positioned and installed through the mounting groove and the vertical rib plates on the inner wall of the semi-finished product thin-wall shell part, and the semi-finished product thin-wall shell part is pressed and fixed through the pressing plates. The drilling tool can accurately position a part to be machined, is firm in positioning, ensures high yield in the subsequent machining process, and improves machining efficiency.
In other embodiments of the present invention, the pressing structure may also be pressed above the thin-walled shell component of the finished plate from top to bottom, rather than being pressed and fixed from the side as in the above embodiments; when the semi-finished thin-wall shell part can be pressed, the pressing plate can be not provided with a long hole; the boss and the base can be integrally formed.
