This structure enables the auxiliary detection tooling body 1 to be connected with the lower fixed plate 709 of the detection device 7 through the base 4, so as to realize the positioning processing of the auxiliary detection tooling body 1 on the detection device 7, and a guide column 708 which is movably penetrated by the movable plate 706 is fastened between the upper fixed plate 704 and the lower fixed plate 709, and the upper end of the movable plate 706 is evenly spaced and connected with The upper fixed plate 704 movably penetrates the limiting rod 705. This structure enables the movable plate 706 to move relative to the upper fixed plate 704 under the limitation of the limiting rod 705. At the same time, the movable plate 706 can move under the limitation of the guide column 708. A wax bag positioning groove 401 for the wax bag 6 to be engaged and positioned is provided in the base 4, and support rods 3 are symmetrically connected to the two sides of the upper end of the base 4. The support rods 3 are an inverted L-shaped structure, and support plates 2 are provided between the support rods 3. The support plates 2 are clamped with springs 5 ​​through clamping holes 202, and the upper movable part of the wax bag 6 is located in the spring 5, and the upper movable part of the wax bag 6 is movably penetrated and matched with the through hole 201. This structure enables the support plate 2 to position the upper end of the spring 5 through the clamping groove 202, and the spring 5 can support The wax bag 6 is supported on the base 4 to perform a stable positioning process on the initial position. After the wax bag 6 is opened, the movable part of the wax bag 6 lifts up the displacement rod 702. A displacement rod 702 corresponding to the position is provided above the base 4. A displacement block 707 is welded and fixed on the upper end of the movable plate 706, and the displacement rod 702 is penetrated and fastened in the displacement block 707 and the movable plate 706. The lower end of the displacement rod 702 is engaged with the movable part of the upper end of the wax bag 6, and the displacement rod 702 is engaged with the upper fixed plate 704. This structure enables the displacement rod 702 and the displacement block 707 to move synchronously. By detecting the height position of the displacement rod 702, the opening stroke of the wax bag 6 at different temperatures is detected. The two ends of the support plate 2 are clamped between the support rods 3 by the short sides of the L-shaped structure of the support rods 3. A through hole 201 is provided on the support plate 2, and a clamping hole 202 communicating with the through hole 201 is provided at the lower end of the support plate 2. A temperature sensor 701 is installed through the upper fixed plate 704, and the temperature sensor 701 and the movable plate 706 are movably arranged through the through hole.

The specific changes of the wax package 6 under various temperature conditions can be seen intuitively.It is helpful for technicians to accurately analyze and evaluate whether the part meets the requirements.

[0019] Working principle: When using the new thermostat wax pack auxiliary detection tooling, first place the wax pack 6 in the wax pack positioning groove 401, and the lower fixing plate 709 makes the auxiliary detection tooling body 1 stable relative to the detection device 7 through the base 4, and then put the spring 5 on the outside of the active part of the wax pack 6, and then make the support plate 2 clamp the upper end of the spring 5 through the clamping hole 202, and the active part of the wax pack 6 penetrates into the through hole 201 to achieve relative stability between the spring 5 and the support plate 2, and then press the support plate 2 downward to compress the spring 5, and after the support plate 2 is pressed down to the bottom of the short side of the L-shaped structure of the support rod 3, the support plate 2 is rotated so that the support plate 2 can be clamped between the support rods 3 to complete the positioning of the wax pack 6. According to the DVP test requirements of the thermostat, the detection device 7 is placed in the water tank as a whole. According to the rise and fall of the temperature, the temperature sensor 701 transmits the temperature change to the computer. At the same time, due to the change of the water temperature, the wax bag 6 will gradually open, so that the active part of the wax bag 6 pushes up the displacement rod 702, and drives the displacement block 707 to move through the displacement rod 702. At this time, the displacement sensor 703 detects the opening stroke of the wax bag 6 according to the different heights of the displacement block 707. The limit rod 705 and the guide column 708 are guided and limited by the moving plate 706, so that the displacement block 707 moves in a straight line. The upper fixed plate 704 is used to stabilize the limit rod 705 and the guide column 708, thereby completing a series of tasks.
