Description

For detecting the gauge of engine cylinder head system valve seating valve line jerk value
Technical field
The utility model relates to a kind of gauge of valve line jerk value, especially a kind of gauge for detecting engine valve seat valve line jerk value.
Background technology
Valve seating valve line (refers to seal band, being commonly used to state the seal band on engine valve and valve seating) requirement of beating is technical requirement important in IC engine gas distribution structure, be directly connected to the performance of engine valve actuating mechanism, along with the development of internal-combustion engine technology, more and more higher to the requirement of valve seating valve line precision, this just requires that we accurately can detect the precision of beating of valve seating valve line.Current, the jerk value of valve seating valve line detects generally three kinds of methods: 1) detect in three-dimensional detection platform, 2) utilize roundness measuring equipment to detect, 3) detect with electronics measurer.Existing detection method, although can realize testing requirement, has following shortcoming: (1) is detected in detection platform, because cylinder cap volume, quality are comparatively large, and carrying inconvenience; (2) above-mentioned three kinds of methods are higher to environmental requirement; (3) equipment addition relative cost is high, particularly three-dimensional and electronics measurer.To beat gauge so seek a kind of economical, simple, easy, efficient detection valve line, be a kind of certainty in actual production life.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, providing a kind of gauge for detecting the pulsation measurement of engine cylinder head system valve seating valve line, can detect valve line jerk value rapidly, improves detection efficiency, reduces testing cost.
According to the technical scheme that the utility model provides, a kind of gauge for detecting engine cylinder head system valve seating valve line jerk value, comprises sounding rod, it is characterized in that: described sounding rod sheathed survey mass and silk dial framework successively from the bottom up; Described survey mass can rotate centered by sounding rod, and the bottom of survey mass is provided with chamfering, and chamfer angle is identical with the chamfer angle of valve seating upper end, and fillet surface is provided with hole, is provided with steel ball in hole, and steel ball is given prominence to survey mass and contacted with valve seating; Described silk dial framework is fixed on sounding rod by the fastening bolt of one end, and the silk dial framework other end is provided with dial gauge and is fixed by milled screw, and the measuring head of described dial gauge contacts with the fillet surface of survey mass upper end.
Described sounding rod lower end is circular cone post, with cylinder cap air valve catheter blind-mate.
The top of described sounding rod is provided with straight pin.
The utility model tool has the following advantages: gauge manufacture is simple, easy to maintenance, to environment no requirement (NR), reduces
Testing cost; Easy-to-use, easy and simple to handle, improve detection efficiency.

Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in figs 1 to 6: the described gauge for detecting head valve seat valve line jerk value comprises sounding rod 1, steel ball 2, survey mass 3, fastening bolt 4, silk dial framework 5, straight pin 6, dial gauge 7, milled screw 8, valve seating 9, cylinder cap air valve catheter 10 etc.
As shown in Figure 1, the utility model comprises sounding rod 1, and sounding rod 1 lower end is circular cone post, with cylinder cap air valve catheter 10 blind-mate, realizes simulating valve seating center; Described sounding rod 1 sheathed survey mass 3 and silk dial framework 5 successively from the bottom up; Described survey mass 3 can rotate centered by sounding rod 1, and the bottom of survey mass 3 is provided with chamfering, and chamfer angle is identical with the chamfer angle of valve seating 9 upper end, and fillet surface is provided with hole, is provided with steel ball 2 in hole, and steel ball 2 is given prominence to survey mass 3 and contacted with valve seating 9; Described silk dial framework 5 is fixed on sounding rod 1 by the fastening bolt 4 of one end, and the other end is provided with dial gauge 7 and is fixed by milled screw 8, and the measuring head of described dial gauge 7 contacts with the fillet surface of survey mass 3 upper end; The top of described sounding rod 1 is provided with straight pin 6, is convenient to take when measuring gauge.
Principle of work of the present utility model and the course of work: as shown in Figure 1, sounding rod 1 and cylinder cap air valve catheter 10 mating die bothridia seat 9 center, in survey mass 3, steel ball 2 contacts with valve seating 9, and the measuring head of dial gauge 7 contacts with the fillet surface of survey mass 3 upper end; Survey mass 3 rotating 360 degrees during use, dial gauge 7 receives the change that steel ball 2 passes over, and departs from the valve line jerk value that the maximum reading in dial gauge 7 center is exactly valve seating 9.
