Abstract

The utility model discloses a measuring device for an outer cone of a bent axle which includes a movement rest, a location block and a V-shaped seat; the location block is fixed at one end of the V-shaped seat through a bolt; the movement rest is fixed at one end of the location block through a bolt; the movement rest is provided with two measuring apparatuses; the V-shaped seat is also connected with a handle. The measuring device of the utility model is matched with a standard stick with conicity of 1 to 50 and can carry out precious measurement on the outer cone of the bent axle, thereby processing the outer cone of the bent axle with the same conicity, realizing the replacement between parts and solving the problem of part waste.

Description

Bent axle male cone (strobilus masculinus) measurement mechanism

Technical field

The utility model relates to the machine parts measurement device, is specifically related to a kind of bent axle male cone (strobilus masculinus) 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 bent axle male cone (strobilus masculinus) of 280 serial diesel engines is 1: 50, does not also have at present to occur accurately measuring the device of the so high bent axle male cone (strobilus masculinus) 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 bent axle male cone (strobilus masculinus) measurement mechanism of dimensional accuracy.

The technical scheme that realizes the utility model purpose is: a kind of bent axle male cone (strobilus masculinus) measurement mechanism, comprise dial framework, locating piece and V-type seat, locating piece is by the end of screw retention at the V-type seat, and dial framework is installed two measurement instruments by the end of screw retention at locating piece on the dial framework.

Also connect one handle on the above-mentioned V-type seat.

The utlity model has positive effect: the measurement mechanism of the present utility model use that matches with the master bar of 1: 50 tapering, can accurately measure the bent axle male cone (strobilus masculinus), thereby process the bent axle male cone (strobilus masculinus) of same tapering, realize the replacement between the parts, solved the problem of parts wastes.

Embodiment

See Fig. 1 and Fig. 2, measurement mechanism of the present utility model comprises dial framework 11, locating piece 12, V-type seat 13 and handle 14, locating piece 12 is fixed on an end of V-type seat 13 by screw 15, dial framework 11 is fixed on an end of locating piece 12 by screw 16, two clock gauges 111,112 are installed on the dial framework 11, handle 14 be located at V-type seat 13 above, this handle be move, the hand-held part in the measuring process.

See Fig. 3 and Fig. 4, it is on 1: 50 the diameter of axle cylindrical 23 of master bar 20 that the V-type seat 13 of determinator of the present utility model is put into tapering, promote entire measuring device by handle 14, with the shaft shoulder 22 of locating piece 12, then

clock gauge

111 and 112 is pressed close to the male cone (strobilus masculinus) 21 of master bar 20 respectively and calibrated near master bar 20.

Using the same method then is put on the diameter of axle cylindrical of bent axle to be processed with measurement mechanism V-type seat 13, promotes entire measuring device by handle 14, with the shaft shoulder of locating piece 12 near bent axle, then

clock gauge

111 and 112 is pressed close to the bent axle male cone (strobilus masculinus) respectively.Compare according to two clock gauges numerical value that shows and the numerical value of calibrating with master bar 20, to be worked into the numerical value that shows on the clock gauge identical with the numerical value of calibrating with master bar 20 always, at this moment promptly finish the processing of the bent axle male cone (strobilus masculinus) of 1: 50 tapering, thereby found the bent axle refill-unit to realize replacement between the parts.
