Description
Technical field
The invention belongs to detection device field, more particularly to a kind of crank spindle roundness and the detection of bent axle coaxiality error
Device.
Background technology
Engine crankshaft is one of very important parts in engine, for the gas force for transmitting piston and connecting rod
It is changed into torque output, to drive coupled power tool, such as flywheel and front-end belt pulley, additionally drives engine
The valve actuating mechanism of itself and its various motion annexes.It can be said that the rotation of bent axle is the power source of engine, and entirely
The driving source of mechanical system.
When engine works, bent axle is acted on by very big gas pressure and inertia force, transmits very high pulling torque, while bent
Axle is acted on by tensile, compressive, bending, torsion quasi-periodic alternate load, therefore this machining accuracy and assembly precision to bent axle proposes
Very high requirement.Wherein the coaxial accuracy of crank spindle roundness and bent axle is one of very important machining accuracy, together
When bent axle be assemblied in again in the bearing hole on engine cylinder-body, crank spindle roundness influences the gap with the assembling of bearing hole,
The coaxial accuracy of bent axle then influences whole engine traveling comfort.
The coaxiality error of usual main bearing journal should be not more than 0.05mm, and error is larger to be referred to as deflection of crankshaft.Work as song
Axle axiality exceedes error amount, will aggravate the abrasion of piston connecting rod unit and cylinder, while influence the gap of lubricating oil film, Jin Erjia
The abrasion of acute main bearing journal and cylinder body upper bearing aperture, can make crankshaft fatigue fracture, cause engine to scrap when serious.Therefore exist
Research and development advanced development or mass-production stage are necessary to each engine crankshaft main shaft roundness (i.e. before bent axle assembling)
Error and bent axle coaxiality error are detected, and could carry out subsequently assembling with the bearing hole on cylinder body after guarantee is qualified.
By taking four-in-line engine as an example, five bearing holes on the trunnion and cylinder body of five shelves of bent axle cooperate,
This fit clearance needs very small, makes engine during high-speed cruising, main bearing journal and the bearing hole on cylinder body it
Preceding formation lubricating oil film, this layer of oil film reduces the coefficient of friction and mechanical loss of bent axle, to improve the operating efficiency of engine,
Make whole engine operation more steady, it is lower to shake noise.
Publication No. CN106017276A, publication date disclose one for the Chinese patent application file on October 12nd, 2016
For kind crankshaft center away from detection instrument, wherein engine crankshaft trunnion deviation from circular from detection means is by the trunnion of crankshaft two end
It is individually positioned in two pieces of V-arrangements supporting on test flat plate, dial gauge gauge stand is fixed on flat board, by adjusting dial framework, made
On table contact alignment crankshaft center trunnion.Dial gauge is proofreaded, then with the slow turning crankshaft of hand one week, reads dial gauge maximum

Thus, after completing school zero, traverse measurement head makes measurement head be in contact with main bearing journal, observes showing for measurement table
Value, complete the detection of bent axle coaxiality error；Rotated by rotatable handle portion band dynamic crankshaft 50, you can complete the main shaft to adjacent shelves
The deviation from circular from of neck 501 is detected, and measurement efficiency is also greatly improved while improving measurement accuracy.
The crank spindle roundness of the present invention and the use of bent axle coaxiality error detection means comprise the following steps (with bag
Include and illustrate exemplified by the bent axle of five shelves)：
First, before using crank spindle roundness and bent axle coaxiality error detection means, measurement module 2 is carried out
Calibration, including calibration plug 40 is fixed between the tailstock component 30 on the top of support bar 10, top component 31, it is ensured that rotate hand
Shank 32 can drive calibration plug 40 easily freely to turn round；The second location nut 231 is unclamped by crossbeam 25 along the first guide rail 23
Rise to measurement position, adjust the extension elongation of the first measurement bar 210 and the second measurement bar 211, make the first measurement head 220 and the
Two measurement heads 221 are in contact with the calibration periphery of plug 40 respectively, and rotatable handle portion 32 drives calibration plug 40 to rotate a circle, and sees
The pointer change of the first measurement table 200 and the second measurement table 201 is examined, adjusts the finger of the first measurement table 200 and the second measurement table 201
Pin, them are made to be directed at the zero graduation of dial plate.
Then, after carrying out school zero to measurement module 2, bent axle 50 to be measured is arranged on to the tailstock component of the bottom of support bar 10
30th, between top component 31, the adjusting bracket of the first location nut 101 is unclamped, then fixes the first location nut 101, unclamp the
Two location nuts 231 make crossbeam 25 be moved down along the first guide rail 23, until 50 first grades of the first measurement head 220 and bent axle
Trunnion 501 is in contact, and the second measurement head 221 is in contact with the trunnion 501 of the second gear of main shaft 50, locks the second location nut
231 fixed cross beams 25, crank handle portion 32 make bent axle 50 rotate a circle, and observe the first measurement table 200 and the second measurement table 201
Change, for roundness error measurement result using the centre of gyration as axis, the difference of maximum indicating value and minimum indicating value is the coaxial of this bent axle
Spend error amount.
Finally, unclamping the 3rd location nut 241 makes the first guide rail 23 be slided on the second guide rail 24 until the first measurement head
It is in contact with the trunnion 501 of the third gear of main shaft 50, the second measurement head 221 is in contact with the trunnion 501 of the fourth speed of bent axle 50,
Locking the 3rd location nut 241 fixes the first guide rail 23, and manipulator's shank 32 rotates bent axle 50 and measured, other adjacent shelves
The measurement of position is carried out with reference to above-mentioned operation successively, so as to complete that whole bent axle is measured.
Because the diameter for calibrating plug 40 is identical with the overall diameter of the trunnion 501 of bent axle 50 to be measured, when the first measurement table
200 and second measurement table 201 complete school zero after, directly crossbeam 25 can be dropped under support bar 10 along the first guide rail 23
Portion, measure the first measurement head 220 and the trunnion 501 of the second measurement head 221 alignment different stalls of bent axle 50, so as to
It can repeat to survey with the trunnion deviation from circular from of the trunnion deviation from circular from of adjacent two gear of one-shot measurement, while adjacent two gear
Amount, so repeatedly measurement is averaged and reduces measurement error, after being measured, it is not necessary to is adjusted survey tool, will need to only be measured
Bar is withdrawn, and is unclamped fixing nut and is moved to next main bearing journal measurement position further along measurement guide rail horizontal direction,
Bent axle is rotated again and completes measurement, so as to improve measurement efficiency and measurement accuracy.
Construction, feature and the action effect of the present invention, above institute is described in detail according to the embodiment shown in schema above
Only presently preferred embodiments of the present invention is stated, but the present invention is not to limit practical range shown in drawing, it is every according to structure of the invention
