A multi-axis tapping device for compressor crankcase stator surface

Abstract

The invention discloses multiaxis tapping equipment for a stator face of a compressor crankcase. A vertical type sliding table with a sliding rail is arranged on the side face of a rack, a main shaft frame is connected with the sliding rail of the vertical type sliding table and provided with a main shaft power head and a driving motor, the driving motor is connected with the main shaft power head through a transmission device, the main shaft power head is connected with at least one multi-shaft tool, each multi-shaft tool is provided with multiple tapping screw taps, a machining platform is located below the tapping screw taps, guide rods which are connected with the main shaft frame are arranged at the two ends of the machining platform, and the machining platform is provided with at least one set of first locating shafts and second locating shafts, wherein the first locating shafts and the second locating shafts are used for locating the compressor crankcase. The multiaxis tapping equipment for the stator face of the compressor crankcase avoids the situation that the positions of holes are not prone to being centered during secondary clamping when tapping is carried out on parts, and improves machining efficiency. Due to the fact that the at least one multi-shaft tool is arranged on the main shaft power head, more than one compressor crankcase can be machined at the same time, and production efficiency can be improved.

Description

technical field [0001] The invention relates to a tapping device, in particular to a multi-axis tapping device for a compressor crankcase stator surface. Background technique [0002] The crankcase of the compressor is an important part of the compressor. The crankcase of the compressor is a box-like part, and the shape of the compressor is usually irregular. like figure 1 As shown, the compressor crankcase 3 is composed of a stator surface 31 and a cylinder surface 32, the cylinder surface 32 is arranged on the edge of the stator surface 31 and is perpendicular to the stator surface 31, the stator surface 31 is provided with a shaft 33, and the shaft 33 is provided with a and the shaft hole 331 on the stator surface 31 , a boss 34 is provided outside the shaft 33 , and a cylinder hole 35 is provided on the cylinder surface 32 . During the assembly process of the compressor, threaded holes need to be processed on the boss 34 and the cylinder surface 32 to facilitate assemb...

AI Technical Summary

Problems solved by technology

Because the boss 34 on the stator surface 31 is different from the cylinder surface 32, it is inconvenient to drill and tap the boss 34 on the stator surface 31. In the process of processing, the boss 34 on the stator surface is drilled first. The hole is then tapped, but the position of the hole cannot be effectively aligned during tapping, and the problem of tap breakage is very easy to occur during tapping, which affects the processing efficiency

In addition, the existing drilling equipment and tapping equipment can only process one part at a time, and the production efficiency is low
