Abstract

The invention discloses a device and a method of a main shaft flange end connecting hole machining in a water pump. The device comprises a template (1), a plurality of positioning holes are uniformlydistributed in the upper edge of the template (1), boring sleeves (2) are arranged in the positioning holes, and bolts (3) and or screw rods which nuts (7) and gaskets (6) are arranged at the two endsof the screw rods are arranged in the positioning holes; and a plurality of screw holes are uniformly distributed in the parts, located in the inner sides of the positioning holes, of the template (1), and connecting screws (4) are arranged in the screw holes. The device and the method of the main shaft flange end connecting hole machining in the water pump have the advantages of being simple instructure, convenient to operate, low in cost and reliable in use; the quality and exchange performance of main shaft flange products machined by different manufacturers and different machine tools can be guaranteed by adopting the device and the method, so that the consistency of the products is controlled; and meanwhile, the machining time and the machining cost are greatly reduced.

Description

technical field [0001] The invention relates to a device and method for processing a connecting hole at a flange end of a water pump main shaft. Background technique [0002] At present, the role of large-scale water pumps is to pump water from low places to high places for storage, which is used for irrigation or to ensure drinking in water-scarce areas. In the water pump unit, there is an important part as the main shaft, whose weight generally ranges from several tons to tens of tons, and the length is more than 3 meters to more than 5 meters; one end of the main shaft passes through the flange and the flange end of the motor shaft through the concave , convex stop for positioning, because the working state is high-speed rotation and needs to transmit huge torque, therefore, it is necessary to design the connecting bolt holes at the two flange ends as positioning screw holes, so that the connecting bolts have both the function of connecting and the transmission of torque ...
