Background technology
The bent axle follow grinding is to be the advanced person's of pivot machining crankshafts connecting rod neck method for grinding with the main bearing journal center; But owing to require high to the circularity of connecting rod neck; So after corase grind, essential through on-position measure circularity, through proofreading and correct the grinding program; Finish grind again, to satisfy the circularity requirement.Because existing method need withdraw from grinding earlier and carry out on-position measure after corase grind, to finish grind again, whole process working (machining) efficiency is low.For overcoming above-mentioned defective; The application number of my application is 20100244618.4 to have proposed " a kind of roundness measurement method of bent axle follow grinding "; Adopted a moving guide rail and pivoted arm that the V-arrangement fork can be moved easily, accurately controlled the length gauge measuring position, emery wheel need not to withdraw from and feeding again; Simple and convenient, production efficiency improves greatly.Yet this patent application has two actions in process; The one, make pivoted arm swing to the action of measuring position mechanism, another is that guide rail moves makes the V-arrangement fork withstand on the action on the measured workpiece, and these two actions are accomplished by two mechanisms respectively; Drive mechanism is complicated; Volume is big, is easy to generate interference, and fault rate is high.
Summary of the invention
The objective of the invention is deficiency, the roundness measurement method of the crank-shaft link neck follow grinding that a kind of structure is simpler, transmission is more reliable, efficient is higher is provided to above-mentioned technology.
Technical scheme of the present invention is following:
A kind of roundness measurement method of crank-shaft link neck follow grinding is adorned a grinding wheel drive mitor seat on the numerical control guide rail, pivoted arm swing seat is arranged on the grinding wheel drive mitor seat; On the pivoted arm swing seat pivoted arm is arranged; Pivoted arm one end is equipped with V-arrangement fork track base, and the V-arrangement fork on the V-arrangement fork track base is contained on the moving guide rail, and V-arrangement is stuck length gauge is housed; It is characterized in that: counterweight at the pivoted arm two ends; Move through moving guide rail pivoted arm two ends weight is changed, and the pivoted arm arm center that rotates is rotated, drive the V-arrangement fork simultaneously and move to and be close to connecting rod neck measuring position.
The present invention also can and move and establish a lever between the guide rail at the V-arrangement fork, is moved by lever drives V-arrangement fork when moving guide rail moves.
The present invention adds man-hour at the bent axle follow grinding, and pivoted arm swings to the action of measuring position and accomplishes with moving guide rail shift action, and is simple in structure, reliable transmission, and fault rate is low.
