Description
Technical Field
The utility model relates to an examine utensil, more precisely is an examine utensil of measuring universal driving shaft thumb pin groove symmetry.
Background
As shown in fig. 6 and 7, in order to ensure that the rotor S1 runs smoothly and without retardation in the stator S2, besides a certain gap is required between the rotor and the stator, the contact stress between the rotor and the surface of the inner cavity of the stator needs to be as consistent as possible during one rotation of the rotor around the inner cavity of the stator, which depends on the symmetry degree of the pin pulling groove on the linkage shaft 4 in spline fit with the rotor, and the pin pulling S3 passes through the pin pulling groove on the linkage shaft 4. If the symmetry is not good, when the rotor drives the linkage shaft to operate, stress which is suddenly large or small occurs between the rotor and the stator due to the deviation of the shifting pin slot of the linkage shaft from one side, so that the uneven abrasion of the rotor and the stator is caused, the service life of the stator and the rotor is influenced, and the phenomenon of clamping stagnation is caused in serious cases. Therefore, the symmetry degree test of the shifting pin hole of the universal driving shaft cannot be ignored.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
As shown in fig. 1 and 2, the checking fixture for measuring symmetry of the universal driving shaft pin slot comprises a V-shaped block 3 and a spline table 2, the spline table 2 is detachably connected with the V-shaped block 3, a V-shaped placing groove 31 is arranged in the middle of the top of the V-shaped block 3, two ends of the top of the V-shaped block 3 are respectively provided with a first connecting hole 32, a spline slot 21 is arranged in the middle of the top of the spline table 2, two ends of the top of the spline table 2 are respectively provided with a second connecting hole 22, and the second connecting holes 22 and the first connecting holes 2 are respectively connected through a connecting screw 1.
The spline groove 21 is a half-circumference internal spline.
When in use, as shown in fig. 3 to 5, a linkage shaft 4 is placed on a V-shaped block 3 and a spline table 2, planes at two sides of a pin pulling groove on the linkage shaft 4 are ensured to be horizontal, then a first pin pulling groove plane I of the pin pulling groove is measured by a lever dial indicator, and a numerical value is read; and the pin is rotated by 180 degrees in the up-down direction, a second pin slot plane II of the pin slot is measured by a lever dial indicator, and a numerical value is read. The difference between the two readings is the symmetry.
The utility model discloses an examine utensil of measuring universal driving shaft thumb pin groove symmetry has following advantage: the utility model discloses fix a position the universal driving shaft with V type piece and spline platform, dial the symmetry in pinhole through the lever percentage table measurement universal driving shaft, because the spline platform is from taking half internal spline in week, with the external spline fit of universal driving shaft, guarantee the accuracy nature of location. The measurement is carried out by turning the universal driving shaft up and down by 180 degrees, and the operation is simple and convenient.
Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention.
