Abstract
The invention relates to the technical field of mechanical part detection devices, in particular to a special measurement device for the degree of symmetry of two key grooves in a shaft. The special measurement device comprises a main frame, supporting devices are arranged on the two sides of the main frame, a measurement device body is arranged in the center of the main frame, each supporting device comprises a pin shaft installed in a corresponding main frame installation hole, and the measurement device body comprises a dial indicator installed in a through hole in the top end of the main frame. The measurement process of the special measurement device for the degree of symmetry of the two key grooves in the shaft is easy and convenient to implement, and measurement precision is high.
Description
Technical field
The present invention relates to mechanical component pick-up unit technical field, particularly relate to two keyway symmetry special measurement device on axle.
Background technology
Axial workpiece is one of typical part often run in Hardware fitting, and it is mainly used to supporting transmission parts, and transmitting torque and bearing load are different by axial workpiece version, generally can be divided into optical axis, multidiameter and special-shaped axis three class; Or be divided into solid shaft, tubular shaft etc.; Axial workpiece often arranges double bond groove, and it is higher to this key grooves accuracy requirement, wherein symmetry error, need to measure cross-section error and length direction error two parts, wherein length direction error is by choose reasonable positioning datum or meticulous centering, and length direction error amount very I is ignored, and therefore mainly measures cross-section error, but cross-section error is due to axle construction restriction measurement comparatively difficulty, and after measuring, precision is not high.
Summary of the invention
The object of this invention is to provide a kind of measuring process easy, two keyway symmetry special measurement device on the axle that measuring accuracy is high.
Technical scheme of the present invention is as follows:
Two keyway symmetry special measurement device on axle, comprise body frame, body frame both sides are provided with bracing or strutting arrangement, and body frame central authorities are provided with measurement mechanism; Described bracing or strutting arrangement comprises the bearing pin be arranged in body frame mounting hole; Described measurement mechanism comprises the dial gauge be arranged in the through hole of body frame top.
Gauge stand is provided with in described through hole.Avoid dial gauge to cause wearing and tearing with by directly contacting by arranging gauge stand, thus extend the serviceable life of dial gauge.
Described bearing pin surface of contact coating one deck titanium nitride layer.Improve the wearing quality of bearing pin.
The invention has the beneficial effects as follows: be supported on by bearing pin on the keyway of both sides on axle, so that the measurement of body frame central authorities measurement mechanism; Realized the measurement of pair cross-section error by dial gauge, improve measuring accuracy.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is body frame, and 2 is mounting hole, and 3 is bearing pin, and 4 is through hole, and 5 is dial gauge, and 6 is gauge stand, and 7 is measured axis.
Embodiment
Shown in Figure 1, two keyway symmetry special measurement device on axle, comprise body frame 1, body frame both sides are provided with bracing or strutting arrangement, and body frame central authorities are provided with measurement mechanism; Described bracing or strutting arrangement comprises the bearing pin 3 be arranged in body frame mounting hole 2; Described measurement mechanism comprises the dial gauge 5 be arranged in body frame top through hole 4; Be supported on by bearing pin on the keyway of both sides on axle, so that the measurement of body frame central authorities measurement mechanism; The measurement of pair cross-section error is realized by dial gauge.
During measurement, body frame is erected on axle, and makes two bearing pins be adjacent to the same side of measured axis 7 double bond groove, move left and right after dial gauge finds the peak of axle, readout value; And then measure with the opposite side of above-mentioned identical mode at measured axis, obtain the numerical value of opposite side peak; The absolute value of last two quantity difference be both on axle double bond groove at the symmetry error in this cross section.
Preferably, gauge stand 6 is provided with in described through hole.Avoid dial gauge to cause wearing and tearing with by directly contacting by arranging gauge stand, thus extend the serviceable life of dial gauge.
Preferably, described bearing pin and measured axis surface of contact coating one deck titanium nitride layer, improves the wearing quality of bearing pin, makes improve more than three times its serviceable life.
Preferably, the thickness of described titanium nitride layer is 5mm, to ensure that nitration case is not easy to wear.
