Can, automotive hub is essential part in automobile component part, and the mounting hole on automotive hub is directly related to its installation
Precision, the position degree detection of automotive hub mounting hole is usually to be detected using common position metric in the prior art,
In use, will test head probes into measured hole, position metric lower surface is needed to be bonded completely with measured workpiece upper surface, laminating degree
It is to carry out resolution observation by testing staff's naked eyes, wastes detection time, detection efficiency is low, while there are still certain subtle mistakes
Difference, detection accuracy is low, influences being normally carried out for installation process, causes security risk to the traveling of automobile.
Summary of the invention
In order to overcome existing position degree detection rule existing insufficient, the present invention provides a kind of high precision position degree detection systems
System, easy to use, detection is quick, time saving and energy saving, improves detection efficiency and detection accuracy, guarantees that workpiece accuracy meets the requirements,
Reduce the quality risk of workpiece.
The technical solution adopted by the present invention to solve the technical problems is a kind of high precision position degree detection system, including
Column, screw, fixing head, fixed plate, detector and labelling apparatus, the fixing head are that T-shaped, the fixing head pass through
Fixed plate, the fixing head are fixedly mounted by screw and column, and the detector, which is connected through a screw thread, to be mounted in fixed plate,
The end of the fixing head is matched with the datum hole of measured workpiece, and the labelling apparatus includes label head, spring, nut, branch
Support set cylinder and bolt, the label head is T-shaped to fall, and the rank matched with label head shapes is provided in the stop sleeve
Terraced slot, the label head are inserted into the dovetail groove in stop sleeve, mark the narrow end of head to be bolted, in the fixed plate
Equipped with slide slot, spring is provided in the slide slot, the wide portion installation of the stop sleeve is contacted with spring, the support sleeve
The narrow portion of cylinder is fixed by nut.
The position of the stop sleeve installation nut is provided with limiting slot, is provided with fastening screw on the nut.
The label head is set as being threadedly coupled with the connection type of stop sleeve.
The invention has the advantages that a kind of high precision position degree detection system, by setting flag device, convenient for differentiating
Easy to use whether detection is accurate, detection is quick, time saving and energy saving, improves detection efficiency and detection accuracy, guarantees workpiece accuracy
It meets the requirements, reduces the quality risk of workpiece.

Specific embodiment
Referring to attached drawing, a kind of high precision position degree detection system, including column 1, screw 2, fixing head 3, fixed plate 4, inspection
Gauge head 5 and labelling apparatus, the fixing head 3 are that T-shaped, the fixing head 3 pass through fixed plate 4, and the fixing head 3 passes through
Screw 2 and column 1 are fixedly mounted, and the detector 5, which is connected through a screw thread, to be mounted in fixed plate 4, the end of the fixing head 3
It is matched with the datum hole 7 of measured workpiece 6, the labelling apparatus includes label head 8, spring 9, nut 11,12 and of stop sleeve
Bolt 13, the label head 8 is T-shaped to fall, and the ladder matched with label 8 shape of head is provided in the stop sleeve 12
Slot 121, the label head 8 are inserted into the dovetail groove 121 in stop sleeve 12, mark the narrow end 81 of head 8 fixed by bolt 13,
It is equipped with slide slot 10 in the fixed plate 4, spring 9 is provided in the slide slot 10, the wide portion 122 of the stop sleeve 12 is pacified
Dress is contacted with spring 9, and the narrow portion 123 of the stop sleeve 12 is fixed by nut 11.
The position that the stop sleeve 12 installs nut 11 is provided with limiting slot 15, is provided with fastening spiral shell on the nut 11
Nail 14 can prevent sleeve 12 from gliding, influence detection accuracy.
The label head 8 is set as being threadedly coupled with the connection type of stop sleeve 12, realizes label head 8 along stop sleeve
12 move up and down, and avoid label head for a long time using abrasion, influence detection accuracy.
When carrying out detection work, fixing head 3 is inserted into datum hole 7, first 5 is will test and is placed at tested gaging hole 61, at this time
Spring 9 in the raw, adjusting nut 11, range difference, that is, quilt of the lower surface of the lower surface and detector 5 of stop sleeve 12
The detected depth of detection hole 61, fixed plate 4 is pushed, and detector 5 is made to enter tested gaging hole 61, and spring 9 is compressed at this time, mark
Note head 8 is contacted with measured workpiece upper surface 62, and label is left on measured workpiece upper surface 62, then illustrates that the measured workpiece 6 is
Qualified product, such as Fig. 2;, whereas if measured workpiece upper surface 62 is not printed on label, then illustrate that the measured workpiece 6 is unqualified,
Such as Fig. 1.
