Abstract
The utility model relates to a crankshaft measuring tool, which comprises a base, a locating slip rod, a slip rod, a slip ring, a guide locating pin, a supporting rod, a percent-meter gauging bracket, a percent-meter gauge, a nut of locating slip rod, a nut of slip rod and a supporting roller. The supporting roller which plays the function of locating is arranged on the base, and the slid rod and locating slid rod are fixed on the base by the nut of slid rod and the nut of locating slid rod respectively. The slid ring is arranged on the locating slid rod by the guide locating pin and the supporting rod is arranged on the slid ring. The percent-meter gauge and the percent-meter gauging bracket are arranged on the supporting rod. During the measurement, the measuring tool which is assembled and checked is arranged on the main axle neck of the crack shaft, the slip ring is pushed to slide along the locating slip rod slightly, so the parallelism error between the baseline of the main axle neck of the crack shaft and the centerline of the crack pin can be measured accurately in the field by the data change in the percent-meter gauge. The device is quick in measurement, high accuracy in detection and easy in operation and can guarantee the process, repair and installment quality of the crack shaft.
Description
The utility model relates to a kind of crank shaft measurement instrument.
Bent axle all requires accurately to detect the parallelism error between king journal center line and the crank pin center line in processing, repairing or installation process.Owing to be subjected to the restriction of survey instrument, bent axle general parallelism error of all failing effectively to carry out between king journal center line and the crank pin center line in processing, repairing or installation process is measured at present.Though quality assurance system manufacturing plant has preferably been carried out this detection after bent axle machines, but employed method mainly is bent axle to be supported on the test flat plate with the V-type frame in the king journal position of bent axle, constantly measure minor increment between crank pin (or a certain crank pin) and the test flat plate along axis direction with micrometer inside caliper then, thereby extrapolate the parallelism error between king journal center line and the crank pin center line, low and the very difficult assurance measuring accuracy of its detection efficiency, in addition along with the continuous development of modern industry, bent axle maximizes day by day, makes this kind detection method be difficult to satisfy the requirement of crank shaft measurement more.
The utility model is intended to avoid the disadvantages of background technology part, provide a kind of and can process at bent axle, the parallelism error in repairing or the installation process between on-the-spot multi-faceted measurement king journal center line and the crank pin center line, and the crank shaft measurement instrument that measuring speed is fast, accuracy of detection is high.
Realize that main technical schemes of the present utility model is: this device is made up of bearing, locating slide rod, slide bar, slip ring, guide positioning pin, support bar, indicator bracket, dial gauge, locating slide rod nut, slide bar nut and supporting roller.The supporting roller that plays the role of positioning is arranged on the bearing, bearing relies on this supporting roller to be placed on the king journal of tested bent axle, slide bar and locating slide rod are fixed on the bearing by slide bar nut and locating slide rod nut respectively, and slip ring is installed on the locating slide rod by guide positioning pin.Support bar is installed on the slip ring, and dial gauge and indicator bracket are installed on this support bar.
During measurement, the good survey instrument of assembling verification is placed on the king journal of tested bent axle (or a certain shaft part), and suitably adjusts indicator bracket and dial gauge, guarantee that the measuring staff of dial gauge is in the crank pin xsect normal direction that gauge head contacts.Pushing away slip ring gently and slowly sliding on locating slide rod, the reading by dial gauge changes the parallelism error that just can on-the-spot accurately measure between this bent axle (or a certain shaft part) king journal center line and crank pin (or a certain crank pin) center line multi-facetedly.
The utility model is compared with background technology has following advantage: adopt method accurate accurate, easy and simple to handle, the parallelism error between king journal center line and the crank pin center line is accurately measured on on-the-spot multi-faceted ground in bent axle processing, repairing or installation process, provide precise information fast for accurately detecting bent axle, guarantee processing, repairing or the installation quality of bent axle, for safe, stable, the long-term operation of compressor creates good conditions.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the assembling synoptic diagram when adopting the utility model to measure the king journal center line of a certain shaft part of bent axle and the parallelism error between the crank pin center line.(Figure of abstract)
Fig. 2 is the scheme of installation of bearing and supporting roller and tested bent axle among Fig. 1.
As depicted in figs. 1 and 2, the crank shaft measurement instrument is made up of bearing (1), locating slide rod (2), slide bar (3), slip ring (4), guide positioning pin (5), support bar (6), dial gauge (7), indicator bracket (8), locating slide rod nut (9), slide bar nut (10) and supporting roller (11).Bearing (1) relies on the supporting roller (11) that plays the role of positioning to be placed on the king journal of tested bent axle.Locating slide rod (2) and slide bar (3) are installed in horizontal and vertical position by bearing (1) center of circle by locating slide rod nut (9) and slide bar nut (10) respectively.Slip ring (4) is installed on the locating slide rod (2) by guide positioning pin (5).Support bar (6) is installed on the slip ring (4), and dial gauge (7) and indicator bracket (8) are installed on this support bar (6).During measurement, the good survey instrument of assembling verification is placed on the king journal of tested bent axle (or a certain shaft part), and suitably adjust indicator bracket (8) and dial gauge (7), guarantee that the measuring staff of dial gauge (7) is in the crank pin xsect normal direction that gauge head contacts.Pushing away slip ring (4) gently and slowly sliding on locating slide rod (2), the reading by dial gauge changes the parallelism error that just can on-the-spot accurately measure between this bent axle (or a certain shaft part) king journal center line and crank pin (or a certain crank pin) center line multi-facetedly.This measurement device speed is fast, accuracy of detection is high, and is easy and simple to handle, can guarantee processing, repairing or the installation quality of bent axle.
Claims (2)
