Abstract
The invention belongs to the field of a machining class and particularly relates to a method for measuring the roundness of a connecting rod neck of a bent shaft during following grinding. The method comprises the following steps of: installing a connecting rod 1 on the center line of a grinding wheel, wherein the connecting rod 1 can freely rotate; enabling the other end of the connecting rod 1 to be connected with a connecting rod 2 through a connecting pin; installing a V-shaped fork on the head part of the connecting rod 2; installing a length gauge on the V-shaped fork to measure the roundness of the connecting rod neck; and enabling the center line of the grinding wheel, the connecting pin and the center line of the connecting rod neck to be parallel. In the invention, the V-shaped fork is closely attached to the connecting rod neck and moves up and down with the connecting rod neck along the grinding wheel during measurement, the connecting rod 1 swings with the connecting rod neck, because the connecting rod 1 and the connecting rod neck both swing by taking the grinding wheel as a center, an included angle positioned between the connecting rod 1 and the connecting rod 2 is unchanged, and only the connecting rod 1 swings with the connecting rod neck so that the pressure acting on the connecting rod and enabling the V-shaped fork to be closely attached to the surface of the connecting rod neck is reduced, thus error values measured at every angle relative to the connecting rod are the error values of the angles of grinding points of the connecting rod neck. The invention has the advantages of simple structure, reliable transmission and low failure rate.
Description
Technical field
The invention belongs to field of mechanical manufacture technology, specifically is a kind of roundness measurement method of crank-shaft link neck 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, in crank-shaft link neck follow grinding process, is a crucial link to the roundness measurement of connecting rod neck; Directly have influence on Accuracy of finish and efficient, in the existing measuring process, the V-arrangement fork is close on the connecting rod neck surface; Along with the connecting rod neck swings up and down with respect to wheel face, support each rod member of V-arrangement fork and also will swing thereupon, each swing arm requires in flexible swinging, to have again high lateral rigidity; To guarantee that beat does not take place the V-arrangement fork in measuring process, along with improving constantly of machine tooling speed, each swing arm swing speed also improves thereupon; To when keeping high flexibility, keep high lateral rigidity more and more difficult; Only reduce swing arm bearing at end gap and reduce flexibility, and make the pressure increase that is added on the swing arm just can make the V-arrangement fork be close to connecting rod neck surface, and the joint is many more; Resistance is big more, has so just influenced the stability of system.
Summary of the invention
The objective of the invention is the deficiency to above-mentioned technology, provide a kind of structure simpler, when measuring, have only a swinging joint the roundness measurement method of crank-shaft link neck follow grinding.
Technical scheme of the present invention is following:
A kind of roundness measurement method of crank-shaft link neck follow grinding is characterized in that: swing arm is contained on the emery wheel center line and can rotates freely, and the other end of swing arm links to each other with connecting rod with connecting pin; Link rod head dress V-arrangement fork, V-arrangement is stuck length gauge is housed, and is used to measure connecting rod roundness; Emery wheel center line, connecting pin, connecting rod neck center line are all parallel, and during measurement, the V-arrangement fork is close on the connecting rod neck; Along with the connecting rod neck moves up and down along emery wheel, swing arm is swung thereupon, because swing arm and connecting rod neck all are to swing with the emery wheel center; So the angle between swing arm and the connecting rod remains unchanged, have only swing arm to swing thereupon, promptly have only a joint swing; So just reduce to act on making the V-arrangement fork be close to the pressure on connecting rod neck surface on the swing arm, reduced measure error.The present invention is simple in structure, reliable transmission, and fault rate is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of roundness measurement method of crank-shaft link neck follow grinding is contained in swing arm 2 on emery wheel 1 center line and can rotates freely; The other end of swing arm 2 links to each other with connecting rod 4 with connecting pin 3, and connecting rod 4 heads dress V-arrangement fork 5 is equipped with length gauge on the V-arrangement fork 5; Be used to measure connecting rod roundness, emery wheel center line, connecting pin 3, connecting rod neck center line are all parallel, during measurement; V-arrangement fork 5 is close on the connecting rod neck 6, and along with connecting rod neck 6 moves up and down along emery wheel 1, swing arm 2 is swung thereupon; Because swing arm 2 all is with the swing of emery wheel 1 center with connecting rod neck 6, so the angle between swing arm 2 and the connecting rod 4 remains unchanged, has only swing arm 2 to swing thereupon; Have only a joint swing, so just reduce to act on making V-arrangement fork 5 be close to the pressure on connecting rod neck surface on the swing arm 2, reduced measure error.
Claims (1)
1. the roundness measurement method of a crank-shaft link neck follow grinding is characterized in that: swing arm is contained on the emery wheel center line and can rotates freely, and the other end of swing arm links to each other with connecting rod with connecting pin; Link rod head dress V-arrangement fork, V-arrangement is stuck length gauge is housed, and is used to measure connecting rod roundness; Emery wheel center line, connecting pin, connecting rod neck center line are all parallel, and during measurement, the V-arrangement fork is close on the connecting rod neck; Along with the connecting rod neck moves up and down along emery wheel; Swing arm is swung thereupon, because swing arm and connecting rod neck all are with the swing of emery wheel center, so the angle between swing arm and the connecting rod remains unchanged.
