Drilling system of belt pulley

Abstract

The invention relates to a belt pulley drilling system. The drilling system is used for drilling a belt pulley. It includes a drilling bracket, a drilling platform is installed on the upper end of the drilling bracket; a positioning unit, the positioning unit includes A positioning seat installed on the upper end of the drilling platform, on the upper end of the positioning seat, there is also a positioning post vertically set to accommodate the middle position of the pulley, and several weight-reducing holes on the pulley are arranged around the positioning post in one-to-one correspondence The positioning pillar; a drilling unit, the drilling unit includes two drill bits that are distributed at a certain angle on the drilling platform, and the front end of the drill bit extends to the upper end of the positioning seat, and the drill bit is driven by the drill bit driver to rotate and Move away from or near the alignment posts. The invention has the advantages that two drill bits distributed at a certain angle are used to drill the pulley at the same time, and only one drilling process can be completed without dividing the process into two, thereby reducing labor force and improving work efficiency.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a belt pulley drilling system. Background technique [0002] The belt pulley belongs to the hub type parts, generally relatively large in size, and the manufacturing process is generally based on casting and forging. Generally, the larger size is designed by casting method, and the material is generally cast iron (good casting performance), and cast steel is rarely used (steel has poor casting performance); generally smaller size can be designed as forging, and the material for steel. Pulleys are mainly used for long-distance transmission of power, such as the output of small diesel engine power, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, some small horsepower motorcycle power Transmission, power transmission of agricultural machinery, air compressor, reducer, reducer...

AI Technical Summary

Problems solved by technology

With this processing method, it is necessary to drill the pulley twice, which is cumbersome to operate and low in efficiency. Moreover, if this step-by-step drilling method is used, it is necessary to mark two positions to be drilled on the pulley in advance. Or before drilling the second hole, manually measure the angle that the pulley needs to rotate, and no matter which one is used, it is necessary to perform the same operation on each pulley during processing, which consumes a lot of manual labor and greatly reduces the work rate. efficiency
