Special abrasive band polishing machine for crankshaft journals

Abstract

The invention relates to a special abrasive band polishing machine for crankshaft journals. The number of clamping mechanisms corresponds to the number of the crankshaft journals; a plurality of grooves used for assembling the clamping mechanisms are formed in a fixed rack; the number of the grooves is equal to the number of the clamping mechanisms; the fixed rack is fixed on a guide sleeve of a guiding mechanism; the guiding mechanism is connected with a machine tool; a hydraulic driving mechanism is connected with the machine tool; the hydraulic driving mechanism is connected with the guiding mechanism and is used for pushing the guiding mechanism to slide front and back; the clamping mechanism are rotatably arranged in the grooves of the fixed rack; an abrasive band in an abrasive band component passes by a reversing mechanism, passes by parts for clamping crankshafts on the clamping mechanisms and then is clamped by reels; a cooling mechanism is fixed above the clamping mechanisms; and after the crankshafts are arranged on the machine tool and are fixed through a rotary clamping part of the machine tool and an ejection connection part of the machine tool, the clamping mechanisms clamp the journals of the crankshafts through control of an automatic control part. The special abrasive band polishing machine is reasonable in structure, simple for manufacture and convenient for operation, and is applicable to crankshaft journal polishing devices of similar crankshafts.

Description

technical field [0001] The invention belongs to the field of crankshaft machining equipment, and in particular relates to a special abrasive belt polishing machine for crankshaft journal polishing. Background technique [0002] At present, in the processing and production of crankshafts, the processed crankshaft body needs to be ground and polished, and the grinding process is mainly to polish the neck of the crankshaft body. The grinding of the traditional technology is generally done directly by the master worker using the grinding machine. When the crankshaft embryo body is grinding, the crankshaft cannot be moved after it is fixed. In this way, the local area of ​​grinding is small. This operation method is simple, but the work efficiency is relatively high. Low, poor grinding efficiency, and wasted a lot of manpower and material resources. There are still some companies using the most expensive polishing machine. Although the polishing machine can automatically complet...

Problems solved by technology

The grinding of the traditional technology is generally done directly by the master worker using the grinding machine. When the crankshaft embryo body is grinding, the crankshaft cannot be moved after it is fixed. In this way, the local area of ​​grinding is small. This operation method is simple, but the work efficiency is relatively high. Low, poor grinding efficiency, and waste a lot of manpower and material resources

There are still some companies using the most expensive polishing machine. Although the polishing machine can automatically complete the polishing of all journals at one time, the effect is better. Using this equipment for repaired or trial-manufactured crankshafts will cause a lot of waste or high production costs.
