Abstract
The utility model relates to a measuring device of a straight ball way inner star wheel forged piece at a high temperature. The measuring device comprises a work table surface which is fixedly provided with a reference heighten block of an inner star wheel. One side of the work table surface is provided with a movable positioning point, and the other side of the work table surface is provided with a fixed positioning point. A spacing distance between the movable positioning point and the fixed positioning point is corresponding to a distance of any two symmetrical grooves of inner star wheel grooves. The measuring device also comprises a meter rod which can be vertically adjusted. An upper end of the meter rod is installed with a dial indicator. A head of the dial indicator is aligned with a highest point of an inner ball way at a 60-degree outer side direction of any boss. The measuring device has the advantages that: measurement is convenient, measurement time is short, a cooling process and auxiliary processing are not needed, a hot forged piece is directly measured, a forging machine does not stop, and continuous production is achieved.
Description
Technical field
The utility model relates to a kind of measurement measurer, relates in particular to a kind of for the measurement measurer (DO series) of liner ball road star-wheel forging under hot conditions.
Background technology
The measuring method of prior art is: when the star-wheel of warm forging depanning, 650 ℃ of its surface temperatures, internal temperature is higher, it is to wait it naturally to cool off that initial workpiece detects, through using behind the bore hole in the plug patchhole, be put on the deflection instrument and survey six alleys 6 times with dial gauge, transfer on the other hand the percentage gauge outfit, another hand turning of work piece rotation 60 degree, to show again to loosen gently, and the searching peak, subtract minimum value by the maximal value that records at last, draw beat whether qualified, the whole time needs more than one hour, and the error of bore hole time folder outside surface location also can produce error to physical size, and the forging press of this moment is in holding state for waiting measurement result, and also there is above-mentioned trouble in patrolling and examining midway.
Summary of the invention
The utility model technical issues that need to address provide a kind of for the measurement measurer of liner ball road star-wheel forging under hot conditions, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: work top; The benchmark keel of fixed in position star-wheel on described work top; Settle activity orientation point in described work top one side, settle a stationary anchor points at described work top opposite side; 2 spacing distance of described activity orientation point and stationary anchor points is corresponding with the distance of any two symmetrical channels of star-wheel groove; Also comprise: the table bar that can vertically adjust up and down; In the table bar upper end that can vertically adjust up and down dial gauge is installed; The peak of the gauge outfit of described dial gauge alley in 60 ° of lateral direction of any one boss are aimed at.
Compared with prior art, the beneficial effects of the utility model are, measuring convenient, time soon, does not need cooling procedure and secondary process, and the forging of heat is directly measured, and forge press is not shut down continuous production.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 1, Fig. 2 as seen: the utility model comprises: work top 4; The benchmark keel 3 of fixed in position star-wheel on described work top 4; Settle an activity orientation point 1 in described work top 4 one sides, settle a stationary anchor points 2 at described work top 4 opposite sides; 2 spacing distance of described activity orientation point 1 and stationary anchor points 2 is corresponding with the distance of any two symmetrical channels of star-wheel groove 5; Also comprise: the table bar 6 that can vertically adjust up and down; In table bar 6 upper ends that can vertically adjust up and down dial gauge 7 is installed; The peak of the gauge outfit of described dial gauge 7 alley in 60 ° of lateral direction of any one boss are aimed at.
The utility model is comprised of position point and measuring point, on a benchmark job face, press the alley shape of alley in the star-wheel, uniform two symmetrical location, certain position of alley peak in 60 of any one boss is outside one's consideration the side direction aligning, the dress upper meter rod, the table bar can vertically be adjusted up and down, and dial gauge is installed in the upper end of table bar.
The star-wheel forging is to be formed by the upper/lower die closure, and upper/lower die directly affects the coaxial examination of lower lane, and because the groove of DO series star-wheel is linear pattern, high-temperature forging is difficult to locking; During measuring workpieces, two anchor points are on the same level line of star-wheel lower lane, and the dial gauge of side also touches the peak of alley groove on the star-wheel simultaneously, and reflect numerical value; Then mention gently, rotate an angle and put down, second numerical value also draws, and is moving while seeing, finishes soon six alleys and measure; The forge press of this moment is in the normal production, and is with machine testing, quality controllable.
Claims (1)
1. one kind is used for the measurement measurer of liner ball road star-wheel forging under hot conditions, comprising: work top; It is characterized in that: the benchmark keel of fixed in position star-wheel on described work top; Settle activity orientation point in described work top one side, settle a stationary anchor points at described work top opposite side; 2 spacing distance of described activity orientation point and stationary anchor points is corresponding with the distance of any two symmetrical channels of star-wheel groove; Also comprise: the table bar that can vertically adjust up and down; In the table bar upper end that can vertically adjust up and down dial gauge is installed; The peak of the gauge outfit of described dial gauge alley in 60 ° of lateral direction of any one boss are aimed at.
