Summary of the invention

At the prior art above shortcomings, the purpose of this utility model provide a kind of cost low, can be efficiently and carry out the medium accuracy axial workpiece automatic detection device that multi-parameter comprehensive detects to axial workpiece exactly; Simultaneously, also can be used for the detection of the middle operation of high precision axial workpiece, find waste product early.

The purpose of this utility model is achieved in that the axial workpiece automatic detection device, comprise the workpiece detent mechanism and the testing agency that are located on the pedestal, detent mechanism is made up of chuck, precision bearing, main shaft and angular transducer, the bottom of chuck cooperates with precision bearing by main shaft, one end chuck for installing of main shaft, other end setting angle sensor;

Testing agency comprises gauge head, the support that inside is equipped with linear bearing, the read head of linear displacement transducer is installed on it, cooperates with axle, linear displacement transducer and planker; Gauge head, support, axle and linear displacement transducer are located on the planker, and planker is located on the pedestal by screw mandrel, rotation nut; The support that supports probe part, the gauge head that contacts with the measured workpiece holding point are installed on the planker, cooperate as radially-directed and move the axle that supports with linear bearing;

One end of the output terminal of angular transducer and linear displacement transducer and data-switching transmitter links, and its other end is the USB serial communication interface, with computing machine or multi-functional display instrument communication.

Compared to existing technology, the utlity model has following advantage:

1, adopts precision bearing (oneself pairing), to guarantee precision simultaneously, do not select air bearing for use, reduce difficulty of processing and cost, and do not need pressurized air and relevant device thereof, improve its scope of application as slew gear;

2, with after the leading screw and nut mechanism improvement, as move axially, detent mechanism, cooperate the error compensation of software, improve its precision; Do not adopt guide rail, reduce difficulty of processing and cost;

3, adopt the micron order linear bearing as radially-directed, travel mechanism, cooperate the error compensation of software, improve its precision; Do not adopt guide rail, reduce difficulty of processing and cost;

4, can carry out the automatic measurement of multiparameter (diameter, circularity and circle are beated) medium accuracy simultaneously to axial workpieces such as multidiameters---after doing suitably to revise, software can be used for measuring the part of other type, as cam, bent axle and disk cover parts etc.;

5, adopt general USB serial communication interface, plug and play is user-friendly to.

The utility model is specially adapted to axial workpiece needs the factories all detected, and it is low to have a cost, efficient height, advantage such as reliable, easy to operate.
