The embodiment of the application discloses a floating mechanism for thread detection.

As shown in fig. 1 to 5, the floating mechanism for thread sensing may include a mounting head 100 and a floating connection member 200.

Wherein a mounting cavity 110 is provided on the mounting head 100. Illustratively, the mounting cavity 110 is disposed on the mounting head 100 in a manner axially recessed from the bottom of the mounting head 100, such that the mounting head 100 is open at the bottom and sealed at the top.

Further, a quick-change joint 130 is provided to the mounting head 100. The quick-change coupler 130 is adapted to be coupled to a drive mechanism of a thread sensing device. Illustratively, the quick-change coupler 130 may be provided in an integrally molded manner on top of the mounting head 100. In the connected state, the quick-change coupler 130 can be connected to the driving mechanism of the thread detecting apparatus by the rotating power pin 710, so that the driving mechanism of the thread detecting apparatus can drive the mounting head 100 to rotate. Through the arrangement of the quick-change connector 130, the floating mechanism and the through-stop detection tool 800 connected to the floating mechanism can be conveniently replaced, so that the floating mechanism for thread detection can specifically select different through-stop detection tools 800 to perform matching detection according to the size of threads. For example, the go-no go detection tool 800 may employ either a go gauge or a no-go gauge.

Wherein, the floating connection member 200 is connected to the mounting head 100 through a transmission connection structure, so that the mounting head 100 can drive the floating connection member 200 to rotate.

Illustratively, the driving connection structure may include a snap 410 disposed on an inner wall of the mounting cavity 110 and a bayonet 420 disposed on the floating connector 200. In the connected state, the clip 410 is inserted into the bayonet 420. And, the size of the bayonet 420 is larger than that of the snap-in piece 410, that is, the length and width of the bayonet 420 are both larger than that of the snap-in piece 410, so that the snap-in piece 410 can move in the bayonet 420 within a certain range, so that the floating connection piece 200 can float along the radial direction and/or the axial direction of the mounting head 100. Wherein, the clip 410 can be a spring bead. In the connected state, the clip 410 is inserted into the bayonet 420, so that the mounting head 100 can drive the floating connector 200 to rotate.

Also, the floating connector 200 can float in the radial direction and/or the axial direction of the mounting head 100.

Wherein the floating connector 200 can be connected with the mounting head 100 by the first floating structure so that the floating connector 200 can float in the radial direction of the mounting head 100.

For example, the first floating structure may include a plurality of second elastic members 510 uniformly arranged on the inner wall of the mounting cavity 110 in the circumferential direction and an annular groove 520 provided on the floating connection member 200. In the coupled state, the plurality of second elastic members 510 are caught in the annular groove 520. In the connected state, the plurality of second elastic members 510 are caught in the annular groove 520, and when the floating connection member 200 is deflected in the radial direction, the second elastic members 510 on the corresponding side are compressed, so that the floating connection member 200 can float in the radial direction of the mounting head 100. Thereafter, the floating connector 200 can be restored by the elastic force of the second elastic member 510. In this embodiment, the second elastic member 510 may employ a spring bead (spring plunger). The number of the second elastic members 510 may be 2, 3, 4, 5, 6, or more.

Wherein the floating connector 200 can be connected to the mounting head 100 by a second floating structure so that the floating connector 200 can float in the axial direction of the mounting head 100.

Illustratively, an annular boss 210 is provided at the top of the floating connector 200. An end cap 120 is provided at the bottom of the mounting cavity 110. The end cap 120 may be fixed to the bottom end of the mounting head 100 by bolts, and a through hole is provided in the middle of the end cap 120. The diameter of the through hole is larger than the diameter of floating connector 200 to facilitate floating of floating connector 200 in the radial and/or axial direction of mounting head 100.

In the installed state, the top of floating connector 200 is disposed in mounting cavity 110 such that annular boss 210 is located in mounting cavity 110 and the bottom extends out of mounting cavity 110 through end cap 120.

A plurality of third elastic members 610 are axially provided on the end cap 120. The third elastic members 610 abut against the annular boss 210 to form a second floating structure. So that the floating connector 200 can float in the axial direction of the mounting head 100 within the elastic range of the third elastic member 610. In this embodiment, the third elastic member 610 may employ a spring bead (spring plunger). The number of the third elastic members 610 may be 2, 3, 4, 5, 6 or more.

In some embodiments, as shown in fig. 3-5, bayonet 420 and annular groove 520 are both disposed on annular boss 210.

Further, a first elastic member 300 is disposed between the top of the floating connector 200 and the top wall of the mounting cavity 110. For example, the first elastic member 300 may employ an elastic washer or an elastic gasket. For example, in the present embodiment, the first elastic member 300 is an elastic O-ring. The top end of the floating connector 200 is flush with the first elastic member 300 and then flush with the top wall of the mounting cavity 110, so that the flatness of the floating connector 200 can be ensured. Therefore, the first elastic element 300, the second elastic element 510 and the third elastic element 610 form comprehensive floating, so that the reliability of screwing of the threads can be ensured, and the success rate of screwing of the first teeth is greatly improved.

Therefore, the floating mechanism for thread detection of this application embodiment sets up to be able to follow through the unsteady connecting piece that will be used for the installation to lead to and ends the detection instrument radial and/or axial of installation head are floated for lead to and end the detection instrument and can guarantee the reliability that the screw thread closed soon, if improve first tooth success rate etc. of closing soon greatly, thereby solve current screw thread detection equipment screw thread and close unsuccessfully, the screw thread leads to and ends rule card and die scheduling problem.
