DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] Example 1

[0023] The present application discloses a galvanic expansion device. Figure 1 and Figure 2 The thermocouple expansion and contraction device includes a base 1, which is used to be installed on a target device, such as a heat treatment furnace. The base 1 partially extends into the target device, and a mounting hole 11 is set through the base 1, and the mounting hole 11 is connected to the inside of the target device. The thermocouple 12 is movably set in the mounting hole 11 and can be expanded and contracted in the target device.

[0024] In order to control the extension and retraction of the thermocouple 12, a control device 2 is also provided on the base 1. The control device 2 can control the extension and retraction of the thermocouple 12 manually or automatically according to actual needs, ensuring that the thermocouple 12 can be extended into the effective working area when needed, and can be retracted when the workpiece enters and exits to avoid collision with the material frame.

[0025] In a specific implementation, a slide seat 21 is slidably disposed in the mounting hole 11, and the thermocouple 12 is mounted on the slide seat 21. When the slide seat 21 slides in the mounting hole 11, it can drive the thermocouple 12 to extend and retract in the target device. The control device 2 indirectly controls the extension and retraction of the thermocouple 12 by controlling the sliding of the slide seat 21.

[0026] The control device 2 includes a mounting frame 22 fixedly connected to the base 1, and a first drive cylinder 23 is fixedly connected to the mounting frame 22. The moving part of the first drive cylinder 23 is connected to the slide 21. When the first drive cylinder 23 is actuated, the moving part pushes the slide 21 to slide in the mounting hole 11, thereby realizing the extension and retraction of the thermocouple 12. The first drive cylinder 23 can be a cylinder or an electric push rod.

[0027] In order to facilitate the connection between the slide 21 and the first drive cylinder 23, a connecting rod 3 is hinged on the slide 21, and a connecting plate 31 is hinged on the connecting rod 3. A plurality of studs 32 are fixedly connected to the moving part of the first drive cylinder 23, and a waist-shaped hole 33 for the studs 32 to pass through is opened on the connecting plate 31. The length direction of the waist-shaped hole 33 is parallel to the moving direction of the moving part, and a locking nut 34 for pressing the connecting plate 31 is threadedly connected to the stud 32. This connection method not only ensures that the slide 21 can move with the movement of the first drive cylinder 23, but also has a certain flexibility and can adapt to different working environments.

[0028] Example 2

[0029] like Figure 3 and Figure 4The embodiment of the present application is different from the embodiment 1 in that a flip seat 4 is rotatably connected in the mounting hole 11, and the thermocouple 12 is mounted on the flip seat 4. A receiving groove 41 for receiving the thermocouple 12 is also provided in the base 1. When the flip seat 4 flips, the thermocouple 12 can be driven to retract into the receiving groove 41, thereby avoiding collision with the material frame. The control device 2 indirectly controls the expansion and contraction of the thermocouple 12 by controlling the flipping of the flip seat 4.

[0030] The control device 2 includes a support rod 43 fixedly connected to the flip seat 4, a second drive cylinder 42 is hinged on the base 1, and the moving part of the second drive cylinder 42 is hinged to the end of the support rod 43 away from the flip seat 4. When the second drive cylinder 42 is in motion, its moving part pushes the support rod 43 to rotate, thereby driving the flip seat 4 to flip, and realizing the extension and retraction of the thermocouple 12. The second drive cylinder 42 can be a cylinder or an electric push rod.

[0031] The expansion and contraction of the thermocouple 12 is realized in the above manner, which makes the operation simple and convenient, and can effectively protect the thermocouple 12, thereby improving the stability and efficiency of the heat treatment process.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
