Description

Technical Field

[0001] This utility model relates to the field of instrument technology, and in particular to a sealing test fixture for instrument processing. Background Technology

[0002] As is well known, an instrument is a device used to measure, display, control, and record various physical or chemical quantities. It is widely used in many fields such as industrial production, scientific research, transportation, medical and health care, and daily life. Usually, after the instrument is manufactured, it needs to be tested for sealing performance using sealing testing fixtures. By simulating the actual working environment pressure and other conditions, the sealing performance of the instrument can be accurately tested, sealing defects can be detected in time, and the instrument can be ensured to have good sealing performance in actual use and meet quality standards and usage requirements.

[0003] However, traditional instrument sealing testing fixtures typically require operators to spend time supporting and adjusting each instrument before testing it, placing it in the right position and maintaining its stability. This can alter the contact between the testing head and the instrument's sealing parts, affecting pressure transmission or gas flow, thus generating testing errors and causing fluctuations in the test results. Consequently, the results cannot accurately reflect the sealing performance of the instrument, necessitating urgent technical improvements. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a sealing test fixture for instrument processing. When in use, the sealing test fixture uses a synchronous motor to drive the screw rod to rotate, which in turn drives the threaded sleeve rod and the connecting rods on both sides to move in opposite directions. As a result, the screw rod moves closer to the outer wall of the instrument and clamps it, ensuring that the instrument remains fixed during the test, which facilitates subsequent airtightness testing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A sealing test fixture for instrument processing includes a mounting frame. Storage slots are formed on the outer walls of adjacent sides of the mounting frame. A screw is rotatably connected to the middle of the bottom and top surfaces of one storage slot, and a guide rod is fixedly connected to the middle of the top and bottom surfaces of the other storage slot. Sliding plates are fitted onto the shafts of both the screw and the guide rod. Installation slots are formed at the upper and lower ends of adjacent sides of the sliding plates. Synchronous motors are fixedly connected to the inner walls of opposite sides of the installation slots. Screws are fixedly connected to the output ends of the synchronous motors. Threaded sleeves are fitted onto the shafts of the screws. Connecting rods are fixedly connected to the upper and lower ends of the threaded sleeves. Clamping semi-rings are fixedly connected to the outer walls of adjacent sides of the connecting rods.

[0007] Compared with existing instrument processing sealing test fixtures, this instrument processing sealing test fixture, when used, drives the screw to rotate by starting the servo motor, which in turn drives the sliding plate on one side to adjust its height. In conjunction with its guide rod, it drives the threaded sleeves on both sides to move up and down, which can adjust the detection component under the instrument to a suitable position, ensuring that the detection head can accurately align with the sealing part of the instrument, improving the accuracy and reliability of the detection, and has high practical performance.

[0008] Furthermore, a PLC control panel is provided on the upper part of one side of the front outer wall of the mounting bracket;

[0009] The above technical solution allows for electrical connection between the PLC control panel and the servo motor and synchronous motor, respectively, facilitating their switching.

[0010] Furthermore, the instrument is tightly fitted to the inner wall of the adjacent side of the clamping semi-ring;

[0011] The above technical solutions facilitate improved coordination through the use of instruments.

[0012] Furthermore, a protective shell is fixedly connected to one side of the upper surface of the mounting bracket, and a servo motor is fixedly connected to the top of the protective shell. The output end of the servo motor passes through a storage slot on one side and is fixedly connected to the upper end of the screw.

[0013] The above technical solution allows for the protection of the servo motor through a protective shell, while the servo motor facilitates the rotation of one of the screws on one side.

[0014] Furthermore, the middle portions of the screw and guide rod are respectively threaded and slidably connected to the sliding plate;

[0015] The above technical solution allows the sliding plate to easily move up and down in coordination with the rotation of the screw.

[0016] Furthermore, each of the threaded sleeves is slidably connected to the inner wall of the mounting groove;

[0017] The above technical solution facilitates the opposing movement of the two clamping semi-rings via the threaded sleeve rod.

[0018] This utility model has the following beneficial effects:

[0019] 1. The present invention proposes a sealing test fixture for instrument processing. Compared with existing sealing test fixtures for instrument processing, when this sealing test fixture is used, the synchronous motor drives the screw to rotate, which in turn drives the threaded sleeve and the connecting rods on both sides to move in opposite directions. As a result, the screw continuously approaches the outer wall of the instrument and clamps it, ensuring that the instrument can remain fixed during the test, which facilitates subsequent airtightness testing.

[0020] 2. The sealing test fixture for instrument processing proposed in this utility model, compared with the existing sealing test fixtures for instrument processing, when in use, drives the screw to rotate by starting the servo motor, and at the same time drives the sliding plate on one side to adjust its height. With the help of its guide rod, it drives the threaded sleeve blocks on both sides to move up and down, which can adjust the detection component under the instrument to a suitable position, ensuring that the detection head can accurately align with the sealing part of the instrument, improving the accuracy and reliability of the detection, and has high practical performance.

[0030] Compared with existing instrument processing sealing test fixtures, this instrument processing sealing test fixture, when in use, drives the screw 21 to rotate by starting the servo motor 25, while simultaneously adjusting the height of the sliding plate 23 on one side. In conjunction with the guide rod 22, it drives the threaded sleeves on both sides to move up and down, which can adjust the detection component below the instrument 12 to a suitable position, ensuring that the detection head can accurately align with the sealing part of the instrument 12, improving the accuracy and reliability of the detection, and has higher practical performance.

[0031] A PLC control panel 11 is provided on the upper part of one side of the front outer wall of the mounting bracket 1;

[0032] The PLC control panel 11 is electrically connected to the servo motor 25 and the synchronous motor 27 respectively, which facilitates the control of their switching.

[0033] The instrument 12 is tightly fitted to the inner wall of the adjacent side of the clamping half ring 211;

[0034] Instrument 12 facilitates improved coordination.

[0035] A protective shell 24 is fixedly connected to one side of the upper surface of the mounting bracket 1. A servo motor 25 is fixedly connected to the top of the protective shell 24.
