At present, most of the technological equipment that requires two arc-shaped surfaces to be processed on the same workpiece is based on the center holes at both ends of the lathe, and the workpiece is processed through turning, milling, grinding, boring and other processes. Complexity, low processing pass rate and high management cost.

Contents of the invention

The invention provides a process equipment for processing a double-arc workpiece by using a vertical lathe, which solves the problems of complex processing technology, low processing pass rate and high management cost in the prior art.

The present invention solves the above problems through the following solutions:

A kind of technological equipment for processing a double-arc surface workpiece by using a vertical lathe, including a square base, four workpiece clamping seats are symmetrically arranged on the same circle with the center of the square base as the center, and a workpiece positioning device is arranged on the workpiece clamping base A cylindrical positioning pin is arranged in the workpiece positioning hole, a workpiece fixture lateral support is provided on the inner surface of the workpiece fixture seat, and a workpiece lateral clamping bolt and a lateral positioning bolt are respectively arranged on the workpiece fixture lateral support. Rod, the positioning through hole of the cylindrical positioning pin is provided between the front and the back of the workpiece to be processed, the positioning hole of the lateral positioning rod is provided on the side of the workpiece to be processed, and the positioning hole of the lateral positioning rod is provided between the top surface and the bottom surface of the workpiece to be processed. The upper and lower vertical direction piercing rod passing holes are provided, the up and down vertical direction piercing rods are provided in the up and down vertical direction piercing rod passing holes, and the upper ends of the up and down vertical direction piercing rods are provided with piercing rod head bolt holes. The lower end of the piercing rod in the vertical direction is provided with a piercing rod tail bolt hole. The threading rod head pull-up bolt passing through the workpiece fixture seat is screwed with the piercing rod head bolt hole, and the threading rod tail pull-down bolt passing through the workpiece fixture seat is connected to the threading rod tail. Bolt holes threaded.

Diamond-shaped positioning pins are arranged between the workpiece fixture seat and the workpiece to be processed, and fixing grooves are arranged on the four corners of the square base.

When the turning tool of the vertical lathe processes the second arc surface of the workpiece along the cutting track, an arc support block is movable between the first arc surface of the workpiece and the inner side of the workpiece holder seat.

The invention has the beneficial effects of reducing the influence of accumulative errors of a series of process systems such as clamping times, repeated positioning of multiple equipment, and tool errors on the machining accuracy of parts.
