According to the invention, the versatility is high, the force source is constant, the variation is small, the measurement precision is high, the influence of human factors is decreased, and the labor intensity is reduced.
Description
Technical field
The invention belongs to measurement mechanism technical field, particularly relate to a kind of splined driveshaft gap self-operated measuring unit.
Background technology
Prior art measures spline gaps by counterweight suspension type, and three grab chuck clamps spline housing cylindrical, and yoke earhole penetrates the plug of length 1200mm, and two ends hang up the counterweight of twice relation to carry out the measurement of spline gaps.Its shortcoming is as follows:
1, holding force is unstable, with scroll chuck by artificial clamping;
2, the strong point has interference to spline gaps measurement, and owing to being vertical measurement, slip shaft yoke pull-out limited length system, so must have the individual strong point;
3, human factor impact is comparatively large, and all processes are all by manually completing;
4, Measuring Time changqiang degree is large, and step is many, workpiece weight;
5, measurement data is unstable, and mechanism is outmoded, and method is relatively ancient.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and the splined driveshaft gap self-operated measuring unit that a kind of stability is high, lower staff labor intensity, increase the benefit is provided.
The object of the invention is to have come by following technical solution, comprise slip shaft yoke, spline housing, loading is pulled out poor, digital display centimeter, described spline housing is placed on one end of slip shaft yoke, and the other end of this slip shaft yoke is slip shaft yoke fork end; Described spline housing cylindrical is located by V-block, and fixes with cylinder-pressing; The both sides that difference is positioned at described slip shaft yoke fork end are pulled out in described loading, and this loading is pulled out difference and is connected with force snesor, and this force snesor is connected with driving tooth bar, and this driving rack and pinion is meshed, and gear is fixed on the driving shaft of stepper motor; The surveyingpin of described digital display centimeter contacts with slip shaft yoke fork end.
As preferably, described force snesor, digital display centimeter are connected with computer by signal data acquisition line.
As preferably, described V-block is positioned at immediately below spline housing cylindrical, and cylinder is positioned at directly over spline housing cylindrical, and V-block and cylinder are corresponding distribution.
As preferably, that described loading is pulled out is poor, drive the plane at the plane at tooth bar place and the slip shaft yoke fork end place of slip shaft yoke in the same plane.
Beneficial effect of the present invention is:
1, V-type location, cylinder-pressing, product highly versatile;
2, measuring process all adopts automatic measurement, reduces human factor impact, reduces labour intensity, avoids erroneous judgement, misjudgement;
3, servomotor driven gear, tooth bar, is provided with force snesor source of exerting all one's strength constant, is deteriorated little in device;
4, data acquisition and automatic production record precision high, use computer for analysis and process data powerful platform, quality tool can be utilized to draw various control chart, and treatment and analysis problem becomes more quick.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Label in accompanying drawing is respectively: 1, digital display centimeter; 2, stepper motor; 3, gear; 4, tooth bar is driven; 5, force snesor; 6, difference is pulled out in loading; 7, computer; 8, cylinder; 9, slip shaft yoke; 10, spline housing; 11, V-block; 91, slip shaft yoke fork end.
Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the present invention: as shown in Figure 1, the present invention includes slip shaft yoke 9, spline housing 10, load pull out differ from 6, digital display centimeter 1, described spline housing 10 is placed on one end of slip shaft yoke 9, and the other end of this slip shaft yoke 9 is slip shaft yoke fork end 91; Described spline housing 10 cylindrical is located by V-block 11, and is fixed with cylinder 8; Eliminate the not of uniform size and spline housing 10 clamped position uncertain factor of artificial clamping force.Described loading is pulled out and is differed from the both sides that 6 are positioned at described slip shaft yoke fork end 91, and this loading is pulled out and differed from 6 and be connected with force snesor 5, and this force snesor 5 is connected with driving tooth bar 4, and this driving tooth bar 4 is meshed with gear 3, and gear 3 is fixed on the driving shaft of stepper motor 2; The surveyingpin of described digital display centimeter 1 contacts with slip shaft yoke fork end 91; Described force snesor 5, digital display centimeter 1 are connected with computer 7 by signal data acquisition line.
Described V-block 11 is positioned at immediately below spline housing 10 cylindrical, and cylinder 8 is positioned at directly over spline housing 10 cylindrical, and V-block 11 is corresponding distribution with cylinder 8; Due to employing is horizontal positioned, and can remove the limited support that slip shaft yoke 9 extracts length direction, spline housing 10 in the raw, does not relate to strong point interference problem.
Described loading is pulled out and is differed from 6, drives the plane at the plane at tooth bar 4 place and slip shaft yoke fork end 91 place of slip shaft yoke 9 in the same plane.
Measuring method of the present invention is: after slip shaft yoke 9 and spline housing 10 coordinate, spline housing 10 cylindrical V-block 11 is located, compress with cylinder 8 again, stepper motor 2 driven gear 3, gear 3 drives tooth bar 4 to make a linear reciprocating motion, drive push-pull effort sensor 5, loading is pulled out and is differed from 6 and complete loading action in slip shaft yoke fork end 91 both sides, after every side has loaded, digital display centimeter 1 will load the fork position numerical value input computer 7 after putting in place by signal trigger-type automatic data collection line, fork position data computer after both sides load carries out calculating and judging automatically, complete measuring process.
This measuring method has:
1, stepper motor and force snesor is utilized to make actual output loads be less than 10% of rated load;
2, line slideway duplicate measurements error is utilized to be less than 10% of franchise;
3, rationally delimit spline and pay tolerance on fit, transmission shaft dynamic balance stability more than 98%;
4, avoid the duplication of labour, lower staff labor intensity, increase the benefit.
Be understandable that, for a person skilled in the art, technical scheme of the present invention and inventive concept be equal to and replace or change the protection domain that all should belong to the claim appended by the present invention.
