Automatic straightening system for miniature assembled crankshaft

Abstract

The invention discloses a miniature assembly crankshaft automatic straightening system which comprises a straightening machine, a straightening tool used for clamping a miniature assembly crankshaft, a feeding and discharging mechanism used for moving and conveying the miniature assembly crankshaft and a control device, and the straightening machine comprises a frame, a loading mechanism arranged in the frame and a pressing head used for straightening the miniature assembly crankshaft. The pressing head can press or be far away from the periphery of the miniature assembly crankshaft, and the loading mechanism is connected with the pressing head to drive the pressing head to ascend and descend. The straightening tool comprises supporting pieces used for symmetrically supporting the two ends of the miniature assembly crankshaft, a rotating piece used for driving the miniature assembly crankshaft to rotate and a measuring device used for measuring the run-out size of the miniature assembly crankshaft, the rotating piece is detachably connected with the periphery of the miniature assembly crankshaft, and the straightening tool is arranged in the frame. The straightening machine, the straightening tool and the feeding and discharging mechanism are all connected with the control device. By using the system, the straightening effect of the shaft rod type workpieces can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of straightening shafts, in particular to an automatic straightening system for miniature assembled crankshafts. Background technique [0002] In the prior art, when performing straightening operations on shaft-like workpieces, cylinders are usually used to tighten the two ends of the shaft, and the micro-assembled crankshaft is driven to rotate through the top friction force. The rotation stability of the shaft-like workpiece is poor, and it will directly This will lead to the deformation of the shaft and rod workpieces. After the deformation, there will be deviations in the measurement runout results of the shaft and rod workpieces, which will lead to wrong alignment results. [0003] To sum up, how to improve the straightening effect of shaft-like workpieces is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the object of the present inven...

[0002] In the prior art, when performing straightening operations on shaft-like workpieces, cylinders are usually used to tighten both ends of the shaft, and the micro-assembled crankshaft is driven to rotate through the top friction force. The rotation stability of the shaft-like workpiece is poor, and it will directly Causes the deformation of the shaft and rod workpieces. After the deformation, there is a deviation in the measurement runout results of the shaft and rod workpieces, which will lead to wrong alignment results
