Abstract
The utility model relates to a coaxiality detecting device which comprises a supporting frame, wherein the supporting frame is provided with an incline which is provided with a positioning disk, the positioning disk is provided with a column groove and a supporting nail used for supporting a workpiece, the distance between the supporting point of the supporting nail and the center of the groove is less than the radius of the groove, the incline above the positioning disk is provided with an auxiliary supporting device, the positioning disk is arranged on the incline and reaches the balance state by using the weight of the workpiece, and a guide rod can automatically adjust the distance under the action of a spring so as to cause a contact between the guide rod and a detected object to be more reliable. The coaxiality detecting device is more convenient for installing the workpiece, improves the detection accuracy because the line contact exists between the detected object and the supporting nail, can achieve the use accuracy requirement because the accuracy can reach the micrometer and is consistent with the accuracy of high precision equipment, and has higher detecting efficiency because the coaxiality of the workpiece can be detected by only rotating one circle by hands.
Description
Technical field
The utility model relates to a kind of axiality detection device, is particularly useful for the detection of oil seal seat right alignment, belongs to mechanical field.
Background technology
At present, right alignment is required in the process of relatively stricter component of machine at oil seal seat etc., detection to its right alignment, usually use three-coordinates measuring machine to measure, this measuring instrument complex structure, the more complicated that in use operates, measuring once needs 15～20 minutes, efficiency ratio is lower, uses inconvenient.
The utility model content
Problem to be solved in the utility model is at above problem, and a kind of easy to use, a kind of axiality detection device that efficient is high is provided.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of axiality detection device, it is characterized in that: this pick-up unit comprises a bracing frame, this bracing frame has a dip plane, on the dip plane, be provided with a positioning disk, positioning disk is provided with cylinder shape groove and is used for nail of supporting workpiece, and the strong point of a nail is to the distance at the groove center radius less than groove, and the dip plane of positioning disk top is provided with auxiliary support apparatus.
Prop up a kind of concrete prioritization scheme of nail, the quantity of a nail is two, and these two nails are along the vertical line symmetric offset spread through the groove center.
A kind of prioritization scheme of auxiliary support apparatus, auxiliary support apparatus comprises a back-up block with cavity, a guide pin bushing is installed in the cavity of back-up block, be provided with guide rod in the guide pin bushing, be provided with spring between guide rod and the guide pin bushing, one end of guide rod stretches out guide pin bushing and passes positioning disk and extend in the groove, and the other end is provided with position-limit mechanism.
A kind of concrete prioritization scheme of position-limit mechanism, position-limit mechanism comprise the external thread that guide rod is provided with and are spun on setting nut on the external thread.
As a kind of concrete prioritization scheme, its end is provided with holds nut.
The utility model adopts above technical scheme, has the following advantages: positioning disk is installed on the dip plane, can utilize the weight of workpiece self to reach equilibrium state, and is easy to use; The setting of auxiliary support apparatus, guide rod are under the effect of spring, and adjustable range makes the contact point between guide rod and the tested article more reliable automatically, and it is more convenient that workpiece is installed; For line contacts, improved accuracy of detection between tested article and the nail, its precision can reach micron, and the precision basically identical with high-precision equipment can reach the service precision requirement; Since only need be with hand with Workpiece Rotating once enclosing the right alignment that can detect workpiece, therefore, detection efficiency is than higher.
