Processing tooling and technology of arc plate parts

Abstract

The invention discloses an arc plate part machining tool which is characterized by comprising a bottom plate, a top plate, a supporting column and locking screws. The bottom plate and the top plate are of cake-shaped structures with the same axis line. The top plate is fixed to the position right above the bottom plate through the supporting column. The edge of the upper surface of the bottom plate and the edge of the lower surface of the top plate directly facing the bottom plate above are sunken to form locating clamping grooves together. At least two locating clamping grooves are uniformlyformed in the peripheral direction of the bottom plate and the peripheral direction of the top plate at intervals. The upper end and the lower end of a single workblank part of a rectangular body shape can be clamped and limited into each locating and clamping groove. Thread holes are formed in the positions, located right above all the locating clamping grooves, of the upper surface of the top plate in a vertical penetrating manner. The locking screws are connected into the thread holes in a rotating manner. The lower end faces of the locking screws are used for abutting against the upper endface of the workblank part located in each locating clamping groove. The invention further discloses a machining technology adopting the arc plate part machining tool.

Description

technical field [0001] The invention belongs to the field of arc plate parts, and in particular relates to a processing tool and technology for arc plate parts. Background technique [0002] Rockets, missiles, and other devices that are cylindrical in shape usually use arc-shaped plate parts inside to play the role of circumferential support (between the inner layer and the outer layer) or radial isolation. [0003] Such as Figure 1 to Figure 4 As shown, it is an arc-shaped plate part, which includes a main part 101, the main part 101 is a plate-shaped structure, and the center of the upper end surface of the main part has an upwardly convex convex shape. Block 102, the projection of the projection 102 in the vertical direction falls on the upper end surface of the main body; the upper and lower end surfaces of the main body 101 are respectively provided with positioning holes; the outer surface of the main body 101 is coaxial from top to bottom The upper arc surface 102 o...

Problems solved by technology

[0004] The existing technologies only use CNC machining centers to process and produce the above-mentioned arc plate parts. However, a single CNC machining center can only cut the outer surface of one blank at a time, and the blank is processed on the CNC machining center. On the fixture, the cutting knife on the CNC machining center needs to move up and down along the set arc surface (the cutting knife needs to move on the XYZ three-axis)

As a result, the processing of a single arc plate part takes a long time, and it is difficult to improve the processing efficiency
