Technical Field

[0001] The invention relates to the field of RVDT detection, in particular to an RVDT automatic comprehensive detection device. Background Art

[0002] RVDT is an angular displacement sensor that uses the differential transformer principle and can output a voltage / current signal proportional to the rotation angle.

The support mechanism 4 is adjusted to move up and down inside the frame 1 by the provided adjustment mechanism 5. When the adjustment mechanism 5 moves upward, the adjustment mechanism 5 will be pressed on the support mechanism 4, and the support mechanism 4 is connected to the adjustment mechanism 5. The detector can perform multi-faceted detection on the RVDT through the support mechanism 4 and the adjustment mechanism 5; when the adjustment mechanism 5 continues to move upward, the adjustment mechanism 5 is separated from the support mechanism 4 connected to it, and when the adjustment mechanism 5 continues to move upward until it is connected to another support mechanism 4, the function of connecting different detectors is achieved; it can be moved according to the motor 51 to achieve rapid adjustment, saving a lot of connection time; the provided extrusion mechanism 6 is used to open the adjustment mechanism 5, and when the adjustment mechanism 5 moves downward, the extrusion mechanism 6 drives the adjustment mechanism 5 to open, so that the support mechanism 4 can move downward from the adjustment mechanism 5; the provided clamping mechanism 7 can clamp the RVDT, and the clamping mechanism 7 clamps the top and bottom of the RVDT respectively, so that the RVDT connection is stable during the connection process.

[0031] The support mechanism 4 includes a support plate 41 arranged inside the frame 1, a measuring instrument is placed on the support plate 41, a plug 42 is provided on the support plate 41, a socket 43 is provided inside the plug 42, the socket 43 is plugged with the connecting line of the measuring instrument, and a terminal 44 is provided on the plug 42, and the terminal 44 cooperates with the adjustment mechanism 5.

[0035] When the terminal 44 is squeezed into the first slot 59, the terminal 44 and the moving block 58 realize electrical conduction and transmit the electrical signal to the RVDT. At this time, the RVDT can be judged according to the value on the detector; when the terminal 44 continues to be squeezed downward from the first slot 59, the terminal 44 enters the second slot 510 from the first slot 59. Since the curvature of the second slot 510 is smaller than that of the first slot 59, the terminal 44 will open the second slot 510, and the terminal 44 will slide out from between the two unfolded moving blocks 58; when the terminal 44 is connected to the first slot 59, the electrical signal will be connected to the connecting wire on the RVDT through the connecting wire on the threaded sleeve to realize electrical signal transmission.

[0038] When the rotating block 57 needs to be moved from the top of the terminal 44 to the bottom of the rotating block 57, when the telescopic rod 67 contacts the first guide groove 64, the support rod 66 will be squeezed on the side wall of the first guide groove 64. At this time, the first guide groove 64 will move under the action of the support rod 66, and the first guide groove 64 will drive the pull rod 62 to move synchronously. The pull rod 62 moves and slides on the surface of the extrusion plate 61, and the extrusion plate 61 drives the rotating block 57 to rotate. The rotating block 57 rotates to leave a gap for the terminal 44 to pass through; when the rotating block 57 moves from the bottom of the terminal 44 to the top, the telescopic rod 67 moves from one end of the second guide groove 65 To the other end, since the bottom of the second guide groove 65 is inclined, the telescopic rod 67 is squeezed by the second guide groove 65 so that the telescopic rod 67 slides toward the inside of the support rod 66; until the telescopic rod 67 slides through the inside of the second guide groove 65; the telescopic rod 67 moves outward from the inside of the support rod 66; and then when the rotating block 57 moves upward, the rotating block 57 will not drive the pull rod 62 to move, and the pull rod 62 is arranged between the guide blocks 54, and the pull rod 62 can slide relatively on the guide blocks 54; when the rotating block 57 moves downward, under the action of the first guide groove 64, the pull rod 62 pulls the rotating block 57 to flip.

[0041] The air storage chamber 71 is provided so as to be inflatable and expand. The air storage chamber 71 is preferably an airbag. After the air storage chamber 71 expands, it drives the top plate 72 to move upward. After the top plate 72 moves upward, it drives the lifting rod 75 to move. The end of the lifting rod 75 is an inclined surface. The lifting rod 75 drives the first push rod 78 to move. The movement of the first push rod 78 drives the first clamping block to move synchronously. The movement of the first clamping block clamps the lower part of the RVDT. When the abutment block 76 moves upward, the abutment block 76 squeezes the abutment joint 711. The movement of the abutment joint 711 drives the second push rod 713 to move. The second push rod 713 drives the second clamping block 714 to move, and then the second clamping block 714 clamps the upper part of the RVDT. Thus, the RVDT is clamped. The connected RVDT is stably connected, and the stably connected RVDT is more stable during the detection process.

[0042] When the present invention is in use, each detector is first placed on the support plate 41, and the connecting wires on each detector are inserted from the jack 43, so that the terminal 44 is electrically connected to each detector; when it is necessary to adjust to the corresponding detector, the motor 51 is started, and the motor 51 rotates to drive the rotating block 57 to move. When the rotating block 57 contacts the terminal 44, the terminal 44 continues to be squeezed downward from the inside of the first slot 59, and the terminal 44 enters from the first slot 59 to the inside of the second slot 510. Since the curvature of the second slot 510 is smaller than that of the first slot 59, the terminal 44 will open the second slot 510, and the terminal 44 will slide out from between the two unfolded moving blocks 58. At the same time, the telescopic rod 67 will move from one end of the second guide groove 65 to the other end, and the telescopic rod 67 will be squeezed by the second guide groove 65 so that the telescopic rod 67 will slide toward the inside of the support rod 66; until the telescopic rod 67 slides through the inside of the second guide groove 65; the telescopic rod 67 moves outward from the inside of the support rod 66; when the rotating block 57 moves downward, under the action of the first guide groove 64, the pull rod 62 pulls the rotating block 57 to flip to both sides. When the terminal is stuck inside the first slot 59, the terminal 44 is electrically connected to the RVDT to measure the angular momentum; when the RVDT is installed, the air storage chamber 71 can be inflated and the air storage chamber 71 expands. The air storage chamber 71 is preferably an air bag. After the air storage chamber 71 expands, it drives the top plate 72 to move upward. After the top plate 72 moves upward, it pushes the lifting rod 75 to move. The end of the lifting rod 75 is an inclined surface. The lifting rod 75 drives the first push rod 78 to move. The movement of the first push rod 78 drives the first clamping block to move synchronously. The first clamping block moves to clamp the bottom of the RVDT. When the abutment block 76 moves upward, the abutment block 76 squeezes the abutment head 711. The movement of the abutment head 711 drives the second push rod 713 to move. The second push rod 713 drives the second clamping block 714 to move, and then the second clamping block 714 clamps the top of the RVDT.
