[0002] Currently, the temperature controller production process requires calibrating the temperature control points in the software, that is, adjusting the temperature control points accurately to meet factory requirements. Currently, adjusting the temperature control points is done by connecting a computer to a LIN programmer, which calibrates the temperature control points.

In the process of temperature controller production, this utility model only requires connecting the temperature controller to the tooling according to a fixed connection method, setting the temperature controller model to be calibrated in the tooling, and the temperature control point of the temperature controller can be calibrated. Compared with the current method of calibrating the temperature control point of temperature controllers, it has the advantages of simple and convenient operation, easy installation and maintenance, no need for computer or LIN downloader support, and can calibrate various models of temperature controllers. Therefore, the tooling has strong applicability.

[0004] However, existing calibration fixtures are prone to poor wire contact during the connection process with the temperature controller. To address this, a fully automatic calibration fixture for the temperature control point of the temperature controller is proposed. Utility Model Content

[0005] To address the issue of poor wire contact that often occurs when existing calibration fixtures are connected to temperature controllers, this application provides a fully automatic calibration fixture for temperature controller control points.

The box body has two sliding grooves, which are slidably connected to the two clamping blocks respectively. The two push rod motors are fixedly connected to the box body, and the output shafts of the two push rod motors are fixedly connected to the two clamping blocks respectively.

[0020] Furthermore, the turntable device includes a turntable and two connecting rods. The turntable is fixedly connected to the inner wall of the box, and both connecting rods are rotatably connected to the turntable. Each of the two connecting rods is rotatably connected to a sliding block.

[0021] Furthermore, the connecting device includes two voltage plates, two screws, two fixing blocks, a motor, and a connecting shaft. Both fixing blocks are fixedly connected to the housing.

[0024] 2. When the PLC module receives the start calibration button command from the touch screen, the PLC module first outputs 24V voltage from the two voltage boards. Then, the LIN calibration module receives the 24V voltage and sends a command to the temperature controller via the LIN port to calibrate the lower limit temperature control point of the temperature controller. If the temperature controller is calibrated successfully, the temperature controller sends a success command to the LIN calibration module via the LIN port, and the LIN calibration module receives the success command.
