To achieve the goals above, the utility model provides the following technical solution:
A kind of multiple degrees of freedom formula Thread check device, including pedestal, lower connecting rod, upper connecting rod and screw thread drift；Institute
It is coaxially connected with Chuck top to state lower connecting rod, the upper connecting rod is flexibly connected by universal joint with lower connecting rod, described
Upper connecting rod is provided with fixing hoop far from one end of universal joint, and the upper connecting rod passes through the outside of bearing and fixing hoop
It is flexibly connected, the opening of the fixing hoop is provided with bolt, and the screw thread drift is locked in fixing hoop.
Further, the upper connecting rod is to be threadedly coupled with the connection type of universal joint；The medial surface of the bearing
It is connect with upper connecting rod far from the pin of universal joint side, the blind hole inner wall on the lateral surface and fixing hoop of the bearing connects
It connects.
Further, the blind hole side of the fixing hoop is provided with through-hole, and the through-hole is connected with blind hole, described logical
Compression pin is provided in hole.
Further, the extended line of the upper connecting rod passes through the center of circle of screw thread drift, straight line where the upper connecting rod
It is perpendicular with the central axis of screw thread drift.
The utility model has the following beneficial effects: a kind of multiple degrees of freedom formula Thread check device, by pedestal, lower connecting rod,
What universal joint, upper connecting rod, fixing hoop, bearing and compression were sold is used cooperatively, and the freedom degree of verifying attachment entirety is higher,
The angle and orientation that screw thread drift can arbitrarily be adjusted in the case where pedestal is fixed in actual use, can greatly facilitate
Detection operation is conducive to improve detection efficiency.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of multiple degrees of freedom formula Thread check device, including pedestal 1, lower connecting rod 2, on
Connecting rod 4 and screw thread drift 6；The lower connecting rod 2 and 1 top of pedestal are coaxially connected, and the upper connecting rod 4 passes through Universal connector
First 3 are flexibly connected with lower connecting rod 2, and the upper connecting rod 4 is provided with fixing hoop 5 far from one end of universal joint 3, it is described on
Connecting rod 4 is flexibly connected by bearing 7 with the outside of fixing hoop 5, and the opening of the fixing hoop 5 is provided with bolt, institute
It states screw thread drift 6 to be locked in fixing hoop 5, the fixing hoop 5 is used for locking screw drift 6, and the screw thread drift 6 is used
It is detected in the external screw thread to workpiece to be detected.
The upper connecting rod 4 is to be threadedly coupled with the connection type of universal joint 3；The medial surface of the bearing 7 and upper company
Extension bar 4 is connected far from the pin of 3 side of universal joint, and the lateral surface of the bearing 7 and 8 inner wall of blind hole on fixing hoop 5 connect
It connects.
8 side of blind hole of the fixing hoop 5 is provided with through-hole, and the through-hole is connected with blind hole 8, sets in the through-hole
It is equipped with and compresses pin 9, the lateral surface for compressing pin 9 and holding out against bearing 7, the compression pin 9 is for keeping bearing 7 and fixing hoop 5
Be fastenedly connected.
The extended line of the upper connecting rod 4 passes through the center of circle of screw thread drift 6, the 4 place straight line of upper connecting rod and screw thread
The central axis of drift 6 is perpendicular.
The universal joint 3 and bearing 7 all have itself damping and amortization, i.e., in the case where not by external force, upper connecting rod 4 with
Angle and corner between lower connecting rod 2 will not change, and the corner between upper connecting rod 4 and fixing hoop 5 will not occur
Variation.
The working principle of the utility model are as follows: fixed pedestal first, when needing the external screw thread using screw thread drift 6 to workpiece
