Tool used for machining large non-metal composite material conical cabin

Abstract

The invention discloses a tool used for machining a large non-metal composite material conical cabin and relates to the technical field of machining tool equipment. The tool used for machining the large non-metal composite material conical cabin comprises a base; two columns of aluminum profile stand rods are installed on the base; parallel longitudinal wire rails are installed at the top ends of each column of aluminum profile stand rods; a blank containing area exists between the two columns of aluminum profile stand rods; a positioning supporting plate is arranged in the blank containing area; a cross beam is arranged above the longitudinal wire rails, and is connected with the longitudinal wire rails through longitudinal sliders; each longitudinal slider is provided with a first guide rail lock; a transverse wire rail is installed on the cross beam; a sliding table is installed on the transverse wire rail and is provided with a vertical guide rail pair; the vertical guide rail pair comprise a vertical slider and a vertical wire rail; the vertical slider is fixedly connected with the sliding table; the bottom end of the vertical wire rail is connected with a marking pin installing base; the vertical slider is provided with a second guide rail lock; the marking pin installing base is provided with a vertical marking pin and a horizontal marking pin; a magnetic grating ruler is installed on each of the longitudinal wire rails and the vertical wire rail; the longitudinal sliders and the vertical slider are each provided with a magnetic head; and a digital display assembly is further installed on the sliding table.

Description

technical field [0001] The invention relates to the technical field of machining tooling equipment, in particular to a tooling used for processing large-scale non-metallic composite conical cabins. Background technique [0002] The traditional cabin processing tooling is a combination of high-precision fixture base and special positioning support to realize product positioning, and then complete the corresponding size processing through a large gantry milling machine. [0003] figure 1 and figure 2 It shows a large non-metal composite conical cabin (made of glass fiber + thermosetting resin). The conical cabin has a small front end, a large rear end, and uniform bulkhead thickness. The two semi-conical cabins (for the convenience of subsequent expression, in the present invention, the plane that divides the conical cabin into two parts is defined as the axial reference plane), during production, the above-mentioned two semi-conical cabins The body is processed separately...

AI Technical Summary

Problems solved by technology

The total length of the conical cabin reaches 6030mm, and the length tolerance is required to be controlled at 10mm. Due to the conical shape of the cabin, it cannot be fixed on the workbench of the gantry milling machine by simple clamping parts such as pressing blocks. The semi-conical cabin blank of metal composite material is a hollow thin-walled part, and it is easy to deform if the clamping force is slightly large. The factory must customize a large fixture with a complex structure to clamp and fix it.

[0004] The price of a large-scale gantry milling machine over 8 meters (the length of the workbench) is generally more than RMB 700,000. figure 1 and figure 2 It is obviously not cost-effective to purchase a large-scale gantry milling machine and customize a complex large fixture for the tapered cabin shown in the figure. In addition, because the fixture for the tapered cabin is bulky and heavy, it must be hoisted to the machine tool It is also difficult to calibrate on the workbench
