Problems solved by technology

As mentioned above in the above patent, the process boss and the part are connected to the part through a rigid connecting bridge, which requires the fitter to break and polish manually, which is inefficient
When the number of process bosses is large and the connection area is large, the manual processing time of the fitter is long, which restricts the production cycle of parts

Embodiment Construction

[0025] Below in conjunction with accompanying drawing and embodiment the present invention will be further described, but the patent of the present invention is not limited to this example.

[0026] A dislocation connection process boss tooling, such as figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a process boss body 1 and a workbench 5. The process boss body 1 is provided with a compression hole 2, and the bolt 6 passes through the compression hole to fix the process boss body 1 on the workbench 5. The process The boss body 1 and the workpiece 4 are connected by a connecting piece, and the connecting piece includes two high-position connecting blocks 7 and low-position connecting blocks 8 respectively. The high-position connecting block 7 and the low-position connecting block 8 are horizontally and vertically Displacement arrangement (such as Figure 6 shown).

[0027] The structure of the dislocation connection boss changes with the processing pr...

Abstract

The invention discloses a staggered connection process boss tool and a method for machining a workpiece. The boss tool comprises a process boss body and a workbench; a pressing hole is formed in the process boss body; a bolt penetrates through the pressing hole to fix the process boss body onto the workbench; the process boss body is connected with the workpiece through connecting pieces; the connecting pieces includes a high-position connecting block and a low-position connecting block; the high-position connecting block and the low-position connecting block are arranged in a staggered mannerin the transverse and longitudinal directions, and the appearance of the workpiece is pressed in the high position and the low position, so that the clamping stability is improved, and the connectingstrength and rigidity of a process boss can be guaranteed even if the area of connecting parts is reduced. A bench worker can break and polish the workpiece easily, and thus the working efficiency ishigh.

Description

technical field [0001] The invention relates to the technical field of numerical control machining technology, in particular to a process boss used for double-sided machining of parts in dislocation connection and a method for machining workpieces thereof. Background technique [0002] With the continuous improvement of performance indicators such as new aircraft maneuverability, flight performance, long life, light weight and low manufacturing cost, aviation structural parts are developing in the direction of integration, thin-walled and precision, which is specifically reflected in the increase in part size , increased thin-walled structures, complex cross-sections and high precision requirements. Since large aeronautical structural parts have many weak rigid structures such as thin walls and deep cavities, the parts are severely deformed during CNC machining, especially for double-sided machining parts. The large amount of material removal and the small thickness of webs ...
