Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig.1,2, a kind of quick test fixture of eccentric shaft concentricity, this test fixture is suitable for processing factory for criticizing
The eccentric shaft test for measuring factory uses, although specific concentricity numerical value can not be provided in the utility model test process,
According to whether within the limits prescribed the concentricity of eccentric shaft can be quickly detected.
The specific structure of this tooling includes pedestal 1, and pedestal 1 is a horizontal positioned plate.The setting of 1 one end of pedestal is fixed
Riser 2, fixed vertical plate 2 and the L-shaped setting of pedestal 1,2 side setting activity riser 6 of fixed vertical plate, movable riser 6 are erected with fixed
Plate 2 is parallel, and movable riser 6 can move in a straight line on pedestal 1 to close to or far from 2 direction of fixed vertical plate, in fixed vertical plate 2
Chuck for installing 3, the one end of chuck 3 for clamping band measurement eccentric shaft.Measuring cylinder 5,5 inner end of measuring cylinder are installed on movable riser 6
With the standard aperture 11 being adapted with the eccentric shaft diameter of axle to be tested, the axis and 3 axis of chuck where the standard aperture 11 are flat.
As shown in Figure 3,4, the application method to carry out the test of 14 concentricity of eccentric shaft using this tooling.Due to practical at this
In novel structure, chuck 3 and 5 axle center of measuring cylinder are in parastate, the standard aperture 11 of measuring cylinder 5 be set as slightly larger than to
The diameter of axle of eccentric shaft 14 is tested, specific size is subject to specific the required accuracy.The axis height of chuck 3 and measuring cylinder 5 differs
The eccentricity of eccentric shaft 14, when 14 one end of eccentric shaft is inserted into chuck 3, the other end theoretically should be coaxial with measuring cylinder 5
The heart.In test process, one end of eccentric shaft 14 is inserted into chuck 3 first, chuck 3 is clamped into eccentric shaft 14, will be surveyed at this time
Graduated cylinder 5 is pushed to close to 3 direction of chuck, if measuring cylinder 5 can smoothly be inserted in eccentric shaft 14, illustrates the coaxial of eccentric shaft 14
Degree, if measuring cylinder 5, which can not be successfully, is inserted in eccentric shaft 14, illustrates that the concentricity of eccentric shaft 14 is not inconsistent in the range of setting
Close prescribed limit.For example, being 10mm when the shaft end processing of eccentric shaft 14,11mm is set by the standard aperture 11 of measuring cylinder 5, is managed
It can be easily plugged into measuring cylinder 5 by upper eccentric shaft 14, but if eccentric shaft 14 is processed unqualified, concentricity is greater than
The error of 1mm judges the coaxial of eccentric shaft 14 then eccentric shaft 14 just can not be normally inserted into measuring cylinder 5 on this basis
Within the limits prescribed whether degree.The measurement tooling of the utility model, suitable for not being extra high batch for required precision
Detection uses when part processing factory, high-efficient, can directly screen the biggish part of error, conducive to the quality of producer
Monitoring.
In order to enhance the applicability of the utility model, facilitate the measurement of part, measuring cylinder 5 is arranged in card the utility model
Immediately below disk 3, the axis of the two is in same vertical plane, and the utility model installs chuck 3 by a ring flange 4
In in fixed vertical plate 2,4 one end of ring flange has connecting shaft 9, is connected between the connecting shaft 9 and fixed vertical plate 2 by bearing 10.
Successively the chuck 3 after method installation is able to carry out rotation, in this way after eccentric shaft 14 is clamped to chuck 3, in its Gravitative Loads
Lower so that chuck 3 rotates, eccentric shaft 14 is naturally drooped, conducive to the position for determining its shaft end.Simultaneously setting measuring cylinder 5 to can be
Adjusting position in short transverse can make 14 automatic centering of measuring cylinder 5 and eccentric shaft in this way in actual test, avoid due to
The problem of the inaccuracy of measurement result caused by mechanical position limitation.
It is provided with horizontal rail 7 on the pedestal 1 of the utility model, there is horizontal slider 8, movable riser 6 in horizontal rail 7
It is fixedly installed on horizontal slider 8, vertical rail 12 is set on the inside of movable riser 6, there is upright slide block 13 on vertical rail 12,
Measuring cylinder 5 is mounted on upright slide block 13, so as to be adjusted in short transverse.To measure by the structure of rail slider
Cylinder 5 is convenient and efficient when being adjusted, and movement is flexible.
The standard aperture 11 of required measuring cylinder 5 is different when due to being directed to the different diameters of axle, different accuracy measurement, in order to increase
Add the versatility of this tooling, then in specific structure, measuring cylinder 5 be designed as to replaceable structure, specifically: in upright slide block 13
One datum plate 15 of upper setting, a positioning pin 16 is arranged on datum plate 15, and 5 outer end of measuring cylinder is equipped with mounting hole 17.Pass through mounting hole
17 and positioning pin 16 cooperation so that between measuring cylinder 5 and datum plate 15 for plug-in connect, replace it is simple and fast.
