A calibration base is mounted on top of the vibration table, and a dial fixing block is bolted to one side of the calibration base. The dial fixing block contains a dial via a snap-fit ​​mechanism. This invention is highly practical.

[0004] However, the above technical solution still has the following problems due to the lack of control during transmitter calibration:

[0005] 1. The transmitter has poor stability during calibration;

[0006] 2. Transmitters often require manual vibration calibration and testing by staff. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies, such as poor stability during transmitter calibration and the need for manual vibration calibration by operators. This invention proposes an integrated vibration transmitter calibration bench.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An integrated vibration transmitter calibration stand includes a base and a hollow movable seat.

[0010] An arc-shaped plate, which is fixedly connected to the top of the movable base;

[0011] A positioning ring is slidably connected to the left side of the arc-shaped plate, and the positioning ring cooperates with the movable seat;

[0012] An eccentric wheel is rotatably connected to the top of the base, and the eccentric wheel is in active contact with the left side of the movable seat;

[0013] The control mechanism includes two push plates, an auxiliary plate, and a positioning plate. The sides of the two push plates that are close to each other are rotatably connected to the front and rear sides of the positioning ring. The auxiliary plate is slidably connected to the top of the movable seat, and the front and rear sides of the auxiliary plate are rotatably connected to the sides of the two push plates that are close to each other. The positioning plate is slidably connected to the right side of the auxiliary plate, and the bottom of the positioning plate is in active contact with the top of the movable seat.

[0014] In a preferred embodiment of this utility model, an auxiliary groove is provided on the top of the base, a sliding plate is slidably connected in the auxiliary groove, and a rack is fixedly connected to the top of the sliding plate.

[0015] As a preferred embodiment of this utility model, a first spring is fixedly connected to the bottom of the positioning plate, and one end of the first spring is fixedly connected to the top of the auxiliary plate. Two second springs are fixedly connected to the left side of the movable seat, and one end of each of the two second springs is fixedly connected to the right side of the base.

[0016] As a preferred embodiment of this utility model, an electric push rod is fixedly connected to the left side of the base, and the output end of the electric push rod is fixedly connected to the front side of the sliding plate.

[0017] In a preferred embodiment of this utility model, a gear is fixedly connected to the top of the eccentric wheel, and the gear meshes with the rack.

[0018] As a preferred embodiment of this utility model, a verification device is fixedly connected to the bottom of the base, and the detection probe of the verification device penetrates through the base.

[0019] Beneficial effects:

[0020] 1. By inserting the transmitter into the moving base, and at the same time extending the detection probe of the calibration device into the transmitter, the operator presses the positioning ring to lower it. At this time, the positioning ring can contact the top of the transmitter when it descends, and at the same time, the descent of the positioning ring can push the two push plates to move.

[0021] 2. The push plate can push the auxiliary plate to move to the right. At this time, the movement of the auxiliary plate can drive the positioning plate to move synchronously. When the positioning plate disengages from the top of the moving seat, the No. 1 spring is initially in a stretched state, which can control the positioning plate to descend and contact the right side of the moving seat, thereby limiting the movement of the positioning ring and ensuring the stability of the positioning ring in fixing the transmitter.

[0022] 3. The output end of the electric actuator can control the sliding plate to move. At this time, the movement of the sliding plate can synchronously drive the rack to move. The rack can control the gear to rotate through the tooth pattern. At the same time, the rotation of the gear can control the rotation of the eccentric wheel. The rotation of the eccentric wheel can cooperate with the second spring to achieve the effect of cyclically controlling the moving seat to drive the transmitter to vibrate. There is no need for the staff to manually control the vibration, which facilitates the calibration device to perform rapid testing.

[0023] In this invention: the transmitter is inserted into the movable seat, at which point the positioning ring can fix the transmitter. At the same time, the detection probe of the calibration device extends into the transmitter. At this time, the electric push rod can assist the eccentric wheel and the second spring in cooperating to cyclically control the movable seat to drive the transmitter to vibrate. There is no need for the operator to manually control the vibration, which facilitates the calibration device to perform rapid testing. Attached Figure Description
