Abstract
The utility model discloses an inner tapered bore measuring device for a crank gear which includes a supporting plate, a touch rod fixing device fixed on the supporting plate and a meter fixing device; a touch rod, the top end of which is provided with a contact, is fixed on the touch rod fixing device; the measuring meter is fixed on the meter fixing device; a location block is arranged above the touch rod fixing device; two location blocks are arranged below the meter fixing device; the three location blocks are on the same plane. The measuring device of the utility model is matched to be used with a standard ring gauge with a taper of 1 to 50 and can carry out precious measuring on the inner tapered bore of the crank gear, thereby processing an inner tapered bore of the crank gear, the inner diameter dimension at the large end of which can be preciously controlled, realizing the replacement between parts and solving the problem of part waste.
Description
Technical field
The utility model relates to the machine parts measurement device, is specifically related to a kind of crankshaft toothed wheel internal taper hole measurement mechanism.
Background technology
The bent axle of 280 serial diesel engines and crankshaft toothed wheel belong to singly joins, and the assembling back does not just have the parts of replacing, in case wherein a kind of damage parts, remaining part is also scrapped simultaneously, and the parts wasting of resources is very serious.
And the tapering of the crankshaft toothed wheel internal taper hole of 280 serial diesel engines is 1: 50, does not also have at present to occur accurately measuring the so high crankshaft toothed wheel internal taper hole device of dimensional accuracy, thereby is difficult to realize the replacement of parts.
The utility model content
The purpose of this utility model is the deficiency at prior art, provides a kind of and can accurately measure the high crankshaft toothed wheel internal taper hole measurement mechanism of dimensional accuracy.
The technical scheme that realizes the utility model purpose is: a kind of crankshaft toothed wheel internal taper hole measurement mechanism, comprise back up pad, be fixed on feeler lever stationary installation and instrument stationary installation on the back up pad, the feeler lever that one top has the contact is fixed on the described feeler lever stationary installation, measurement instrument is fixed on the described instrument stationary installation, feeler lever stationary installation top is provided with a positioning block, instrument stationary installation below is provided with two locating pieces, and these three locating pieces at grade.
The utlity model has positive effect: the measurement mechanism of the present utility model use that matches with the ring standard gauge of 1: 50 tapering, can accurately measure the crankshaft toothed wheel internal taper hole, thereby process the crankshaft toothed wheel internal taper hole that big end internal diameter size can accurately be controlled, realize the replacement between the parts, solved the problem of parts wastes.
Description of drawings
Fig. 1 is a measurement mechanism structural drawing of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the synoptic diagram of determinator of the present utility model with the ring standard gauge calibration.
Embodiment
See Fig. 1 and Fig. 2, determinator of the present utility model comprises back up pad 11, be fixed on feeler lever stationary installation 12 and instrument stationary installation 13 on the back up pad 11, the feeler lever 122 that one top has contact 121 is fixed on the feeler lever stationary installation 12 by nut 123, clock gauge 131 is fixed on the instrument stationary installation 13, feeler lever stationary installation 12 tops are provided with a positioning block 14, and instrument stationary installation below is provided with two locating pieces 14, and these three locating pieces at grade.
See Fig. 3, three locating pieces 14 of determinator of the present utility model are close to the major part reference field 21 that tapering is 1: 50 a ring standard gauge 20, feeler lever 122 and clock gauge 131 are stretched into certain distance in the internal taper hole of ring standard gauge 20, the inner conical surface 22 that makes the gauge outfit of contact 121 and clock gauge 131 contact ring standard gauge 20 is respectively calibrated.
Use the same method then and three locating pieces 14 of determinator are close to the major part reference field of crankshaft toothed wheel to be processed, feeler lever 122 and clock gauge 131 are stretched into distance same in the crankshaft toothed wheel internal taper hole, make the gauge outfit of contact 121 and clock gauge 131 contact the crankshaft toothed wheel inner conical surface respectively, compare according to numerical value that shows on the clock gauge and the numerical value of calibrating with ring standard gauge 20, to be worked into the numerical value that shows on the clock gauge identical with the numerical value of calibrating with ring standard gauge always, at this moment promptly finished the processing of the crankshaft toothed wheel internal taper hole of 1: 50 tapering, thereby find the crankshaft toothed wheel refill-unit, realized the replacement between the parts.
