Multistation automatic perforating machine for bicycle crank

Abstract

The invention relates to a multistation automatic perforating machine for a bicycle crank. The multistation automatic perforating machine for the bicycle crank comprises a base and a machine body; the machine body is arranged on the base; a group of vertical rotating shafts are arranged on the machine body; the rotating shafts are driven by a motor arranged on the back of the machine body; the lower end of each of the rotating shafts is connected with a drilling head; each drilling head is driven by a drilling head hydraulic cylinder arranged at the upper end of the machine body to do vertical motion; and a workpiece location table is arranged on the machine body below each drilling head. The invention is a multistation automatic perforating machine which has rational design and high automation degree, and is easy to operate and suitable for popularization and use in large-scale industrial production; and the bicycle crank can be machined by a simultaneous multistation automatic perforating method, so the production efficiency is improved, the product quality is guaranteed and the labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the field of bicycles, and relates to a bicycle crank, in particular to a multi-station bicycle crank automatic punching machine. Background technique [0002] A bicycle crank is a part that connects the pedals and the car body. It is usually a strip-shaped plate. A mounting hole is formed at both ends of the crank to install the pedals and the center shaft. At present, the manual drilling machine is widely used in the processing of the mounting holes at both ends of the crank. The disadvantages are: 1. The processing efficiency is low, and only one workpiece can be processed at a time. The processing speed is slow and it is not suitable for large-scale production; 2. The labor load is large. , the positioning of the manual drilling machine is laborious, and the workpiece needs to be positioned before the crank mounting hole is processed. The labor load of the workers is large, and they are prone to fatigue and work-related acc...

The labor load is large. , the positioning of the manual drilling machine is laborious, and the workpiece needs to be positioned before the crank mounting hole is processed. The labor load of the workers is large, and they are prone to fatigue and work-related accidents; 3. The scrap rate is high, and the manual operation is limited by the technical level and proficiency. Many, the scrap rate is high, and the waste of raw materials is more, which will increase the production cost of the enterprise
