Abstract
The invention belongs to the machining class, and in particular relates to a roundness measurement method for bent axle follow-up grinding, which is characterized in that a numerical control guide rail is provided with a grinding wheel motor cabinet provided with a tumbler swinging seat; the tumbler swinging seat is provided with a tumbler below which a stop dog is arranged; one end of the tumbler is installed on the tumbler swinging seat, and the other end of the tumbler is provided with a V-shaped fork guide rail seat of which the movable guide rail is provided with a V-shaped fork; the V-shaped fork is provided with a length gauge; the V-shaped fork and the length gauge contact with a workpiece under the movement of the V-shaped fork guide rail; when the roundness of the workpiece needs to be measured, the bottom of the tumbler is contacted with the stop dog; and the V-shaped fork movable guide rail moves, so that the V-shaped fork is tightly adhered to the workpiece while the length gauge is contacted with the workpiece to measure the roundness of the workpiece. When a bent axle is ground and processed, the V-shaped fork movable guide rail is adopted to conveniently move the V-shaped fork and the length gauge, the roundness of the bent axle can be conveniently measured after the bent axle is subjected to rough grinding, and then the bent axle is subjected to accurate grinding. In the working process, the grinding wheel does not need to retreat and feed again, thus the method is convenient and simple, and greatly improves the production efficiency.
Description
Technical field
The invention belongs to field of mechanical manufacture technology, specifically is a kind of roundness measurement method of bent axle follow grinding.
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, can be with same benchmark (being the trunnion center) machining crankshafts trunnion and connecting rod neck, but because the circularity of main bearing journal and connecting rod neck requires high (general error is in 3 microns), so after the bent axle corase grind, essential through on-position measure circularity, by proofreading and correct the grinding program, carry out precision again, to satisfy the circularity requirement.Concrete grammar as shown in Figure 1, adorn a grinding wheel drive mitor seat 2 on numerical control guide rail 1, pivoted arm swing seat 3 is housed on grinding wheel drive mitor seat 2, pivoted arm 4 one ends of swinging seat 3 at pivoted arm are equipped with V-arrangement fork 7, V-arrangement is equipped with a length gauge 8 on pitching 7, and pivoted arm 4 can be swung on grinding wheel drive mitor seat 2.When needs were measured grinding work piece circularity, the pivoted arm bottom was close to workpiece 9 by V-arrangement fork 7, and length gauge 8 contacts with workpiece 9.If measuring workpieces connecting rod neck, pivoted arm swing seat rotates synchronously with workpiece, calculates the workpiece connecting rod roundness according to the numerical value change of length gauge; When the measuring workpieces trunnion, workpiece rotation calculates the work spindle roundness according to the numerical value variation of length gauge.Because the shape of pivoted arm and length are fixed, so when measuring, grinding wheel drive mitor and workpiece centre must be maintained a certain distance, emery wheel must be withdrawed from during measurement, the process of whole like this in-process measurement has just become that corase grind, emery wheel withdraw from, the pivoted arm bottom, measure pendulum on circularity, the pivoted arm, correct grinding, carry out on-position measure because need withdraw from grinding after corase grind, working (machining) efficiency is affected like this, and production efficiency reduces.
Summary of the invention
The objective of the invention is deficiency at above-mentioned technology, a kind of grinding is provided and on-position measure circularity operation is more reasonable, efficient is higher, processing simpler bent axle follow grinding the roundness measurement method.
Technical scheme of the present invention is as follows:
A kind of roundness measurement method of bent axle follow grinding, it is characterized in that: adorn a grinding wheel drive mitor seat on the numerical control guide rail, one pivoted arm swing seat is arranged on the grinding wheel drive mitor seat, on the pivoted arm swing seat pivoted arm is arranged, there is a block pivoted arm below, pivoted arm one end is contained on the pivoted arm swing seat, the other end is equipped with V-arrangement fork track base, on the moving guide rail on the V-arrangement fork track base V-arrangement fork is housed, and V-arrangement is stuck length gauge is housed, the V-arrangement fork moves down at the moving guide rail of V-arrangement fork with length gauge and contacts with workpiece, when needing measuring workpieces circularity, the pivoted arm bottom is run into block, and the moving guide rail of V-arrangement fork moves, make the V-arrangement fork be close to workpiece while length gauge and contact measuring workpieces circularity with workpiece.Make the V-arrangement fork be close to workpiece because V-arrangement fork guide rail can move, get final product measuring workpieces circularity so emery wheel can withdraw from.
The present invention is when the measuring workpieces connecting rod roundness, grinding wheel drive mitor seat and workpiece rotate synchronously, calculate the workpiece connecting rod roundness according to the length gauge numerical value change, when the measuring workpieces trunnion, the workpiece rotation calculates the work spindle roundness according to the length gauge numerical value change.
The present invention adds man-hour at crankshaft grinding, when especially in process, needing on-position measure bent axle circularity to adjust procedure, adopted the moving guide rail of V-arrangement fork that V-arrangement fork and length gauge are moved easily, make bent axle after corase grind, can measure circularity easily, and then finish grind again, emery wheel need not to withdraw from and feeding again, and simple and convenient, production efficiency improves greatly.
