Description

Technical Field

[0001] The utility model mainly relates to the technical field of thermostat wax package experiments, and particularly provides a verification experiment tooling for a thermostat wax package that is convenient for disassembly and assembly. Background Technique

[0002] The core function of the thermostat wax package is to control the flow direction of the coolant according to temperature changes. Different paraffin wax ratios will cause the wax package to expand at different temperatures, affecting the opening temperature of the thermostat. Through verification experiments, the optimal paraffin wax ratio can be found to ensure that the thermostat opens and closes accurately within a predetermined temperature range, thereby optimizing the temperature management of the engine; through verification experiments, it helps to determine which ratio can provide the most accurate response at the required temperature.

[0003] Currently, the wax package verification experiment tooling includes a wax package sample similar to the physical wax package component and a tooling component for assisting the telescopic movement of the wax package sample. Among them, the wax package sample is the same as the physical wax package component and cannot be reworked after riveting is completed, resulting in that one wax package sample can only verify one paraffin wax selection, and multiple experiments are required to verify the paraffin wax ratio. This requires manufacturing multiple wax package samples, causing unnecessary resource waste. In addition, the existing tooling components for wax package verification experiments usually need to be disassembled and assembled through connecting parts such as screws and bolts, and multiple experiments are required to verify the paraffin wax ratio, resulting in frequent disassembly and assembly operations of the tooling components, that is, frequent disassembly and assembly of screws, bolts, etc., and the operation is relatively inconvenient. Summary of the Utility Model

Several embodiments of the present utility model are given in the drawings, but the present utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive.

[0025] It should be noted that unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] Embodiment I: Please refer with emphasis to the attached Figure 1 - attached Figure 3 , a thermostat wax package verification experiment tooling that is convenient for disassembly and assembly, including a wax package sample and tooling components.

[0027] The wax package sample includes:

[0028] The barrel sleeve 1 is a cylinder with one end open, and its open end is provided with external threads. The overall material is copper. A sealing body and a guiding ring (not shown in the figure) are provided at the open end of the barrel sleeve 1 for sleeving on the push rod 3 to prevent liquid leakage.

[0029] The barrel cap 2 is provided with internal threads and is sleeved on the open end of the barrel sleeve 1 through the threads. The overall material is copper.

[0030] The push rod 3 is longitudinally and penetratingly arranged at the center of the barrel cap 2 and extends into the barrel sleeve 1.

[0031] The tooling assembly includes:

[0032] The base 4 has a groove 41 at its center that communicates with its upper end face for inserting the wax package sample (mainly for the push rod 3 to insert). Two opposite sides of the base 4 are fixedly connected with limiting columns 42 extending upward. At the top of the opposite sides of the two limiting columns 42, bumps 421 are formed. At both ends of the top surface of the frame plate 6, clamping grooves 61 for the bumps 421 to be inserted are provided, and the width of the frame plate 6 is greater than the width of the bumps 421. On both sides of the clamping grooves 61 on the frame plate 6, limiting parts 611 for abutting against the bumps 421 are formed.

[0033] The main spring 5 is located above the base 4 and is used for sleeving on the barrel sleeve 1.

[0034] The frame plate 6 is located above the main spring 5. A through hole for sleeving on the barrel sleeve 1 is provided at the center of the frame plate 6 and can rotate around the barrel sleeve 1.

[0035] During application, in the assembly stage: First, pour paraffin into the barrel sleeve 1, then pass the push rod 3 through the barrel cap 2, and install the sealing body and the guiding ring. Then, thread the barrel cap 2 onto the barrel sleeve 1. Finally, adjust the length of the push rod 3 inserted into the barrel sleeve 1 to form the wax package sample. After that, insert the wax package sample on the base 4, insert the push rod 3 downward into the groove 41, and the barrel cap 2 just rests on the upper end face of the base 4. Then, sleeve the main spring 5 on the barrel sleeve 1, and finally sleeve the frame plate 6 on the barrel sleeve 1. Press down and rotate the frame plate 6 until its two ends are located on the side where the limiting columns 42 are located. After releasing, the main spring 5 pushes the frame plate 6 upward, and the bumps 421 just snap into the clamping grooves 61 to limit the upward movement of the frame plate 6; and the two limiting parts 611 at the ends of the frame plate 6 clamp the bumps 421, hindering the rotation of the frame plate 6.

[0036] Verification stage: Place the entire tooling in the water boiling tank. A displacement sensor is set above the barrel sleeve 1, and a temperature sensor is set in the water boiling tank. Both the displacement sensor and the temperature sensor are electrically connected to the controller. Then, conduct an experimental verification of the initial opening temperature / full opening temperature / full opening lift of the wax package: During the heating process, the paraffin expands, pushing the push rod 3 downward. However, due to the restriction of the base 4, the push rod 3 cannot move downward, and the reaction force causes the barrel sleeve 1 and the barrel cap 2 to move upward, compressing the main spring 5. When the displacement sensor detects an upward displacement of the barrel sleeve 1, record the temperature value detected by the temperature sensor at this time, which is the initial opening temperature; when the displacement sensor detects that the position of the barrel sleeve 1 stops moving upward, record the temperature value detected by the temperature sensor at this time, which is the full opening temperature. At the same time, record the displacement value detected by the displacement sensor at this time, which is the full opening lift.

[0037] Disassembly stage: After recording the experimental data, take the tooling out of the water boiling tank. Press down and rotate the frame plate 6 until its two ends are far away from the limit posts 42, then the frame plate 6 and the main spring 5 can be easily removed. Then, pull out the wax package sample, unscrew the barrel cap 2 to replace the newly configured paraffin.

[0038] Repeat the above steps to complete multiple experimental verifications of different paraffin ratios.

[0039] As can be seen from the above, the utility model adopts a detachable wax package sample, and multiple experiments with different paraffin ratios can be realized by using one wax package sample, thus saving the labor cost and material cost in the sample manufacturing process. Moreover, the disassembly and assembly operations of the tooling components are relatively convenient and easy to apply.

[0040] Embodiment 2: The difference between this embodiment and Embodiment 1 is as follows:

[0041] Please refer to Attachment Figure 1 and Attachment Figure 2 In this embodiment, the opposite sides of the two limit posts 42 are both arc-shaped surfaces, and the arc-shaped surfaces are coaxially arranged with the groove 41. The two ends of the frame plate 6 are arc-shaped surfaces that respectively fit the arc-shaped surfaces of the two limit posts 42. This setting makes the contact gap between the limit posts 42 and the frame plate 6 smaller, which is conducive to improving the compactness of the tooling structure. At the same time, it can optimize the deflection performance of the frame plate 6.

[0042] In this embodiment, please refer to Attachment Figure 3 The groove 41 is a multi-stage annular groove, and the diameter of the annular groove increases sequentially from bottom to top. The annular groove at the bottom is adapted to the push rod 3, and the barrel cap 2 is formed with an annular edge 21 that is placed on the upper end surface of the base 4. It is used to improve the insertion stability of the wax package sample.

[0043] In this embodiment, please refer to Attachment Figure 1 and Attachment Figure 3The end surface of the tube cap 2 facing the tube sleeve 1 is formed with a concave annular groove 22, and one end of the main spring 5 is placed in the annular groove 22. The side surface of the frame plate 6 contacting the main spring 5 is provided with a limiting groove 62 for accommodating the other end of the main spring 5. In this way, a certain limiting effect can be achieved on the main spring 5, which is conducive to ensuring the stability of the position of the main spring 5.

[0044] The rest is the same as the first embodiment.

[0045] Embodiment 3: This embodiment differs from Embodiment 2 in that:

[0046] In this embodiment, please refer to the attached Figure 3 The push rod 3 is fixedly connected to the portion located outside the barrel cap 2 with a stopper 31 for contacting the end of the barrel cap 2 facing away from the barrel sleeve 1. By using the stopper 31 contacting the barrel cap 2 as a standard, the length of the push rod 3 inserted into the barrel sleeve 1 can be adjusted, thereby adjusting the distance between the outer end of the push rod 3 and the annular edge 21, so that when the push rod 3 contacts the bottom of the groove 41, the annular edge 21 just rests on the upper end surface of the base 4.

[0047] The rest is the same as the second embodiment.

[0048] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
