If it malfunctions, it will directly affect the normal operation of the engine. Therefore, a comprehensive testing mechanism that can adapt to various thermostats is needed.

[0003] In the traditional process of testing thermostats, the post-test marking of products relies heavily on manual operation. Manual marking is not only inefficient, but may also lead to confusion between qualified and unqualified products due to operational negligence. In addition, the large number of manual steps will prolong the testing cycle of a single product, making it difficult to meet the high-efficiency testing requirements of large-scale mass production. To solve the above problems, this application proposes a comprehensive testing mechanism that is adaptable to various thermostats. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-2 A comprehensive testing mechanism adaptable to various thermostats includes a base 1, which provides the mounting foundation for the entire testing mechanism, supports all components, and ensures their relative position stability. A limiting mechanism is provided on the top of the base 1, including a fixture plate 4 fixedly connected to the top of the base 1. The base 1 and the fixture plate 4 are fixedly installed by bolts. Multiple mounting holes are provided on the base 1, allowing for the replacement of fixture plates 4 with different shapes by installing bolts into these holes. This adapts to thermostat products of different shapes and specifications, enabling the testing of thermostat products of various shapes and specifications. The fixture plate 4 provides a placement platform for the thermostat products. A contouring seat 5 is fixedly connected to the top of the fixture plate 4. The contouring seat 5 conforms to the shape of the thermostat product for initial positioning, preventing displacement during placement. Two support positioning columns 6 are fixedly connected to the top of the fixture plate 4. The support positioning columns 6 assist the contouring seat 5 in limiting the product's position, ensuring the product's position is fixed during testing.

[0022] Two pairs of uprights 2 are fixedly connected to the top of the base 1. The four uprights 2 are fixedly connected to the top plate 3. The top plate 3 is equipped with a first cylinder 7 that is fixedly connected to it. The first cylinder 7 acts as a drive source and drives the connecting plate 8, lifting plate 9 and other components to press the product by extending and retracting the output end. The top output end of the first cylinder 7 is fixedly connected to the connecting plate 8. The bottom of the connecting plate 8 is fixedly connected to the lifting plate 9. The lifting plate 9 carries the pressure plate 12 and the elastic mechanism. Driven by the first cylinder 7, it drives these components to lift and lower as a whole. The bottom of the lifting plate 9 is fixedly connected to the pressure plate 12. The pressure plate 12 is equipped with four pressure heads 13 that are fixedly connected to it. The pressure heads 13 are in direct contact with the product. The pressure transmitted by the pressure plate 12 firmly presses the product onto the tooling plate 4 to prevent shaking during testing.

[0023] The top plate 3 has two first guide rails 10 fixedly connected to its side wall. Each first guide rail 10 has a first slider 11 slidably connected to its outer wall. The first guide rail 10 restricts the movement trajectory of the first slider 11 to ensure that it moves only in the vertical direction. Both first sliders 11 are fixedly connected to the lifting plate 9.

[0024] A displacement sensor 16 is provided on one side of the lifting plate 9 to detect the insertion depth of the probe. A spring mechanism is provided above the pressure plate 12. The spring mechanism includes a second guide rail 14 fixedly connected to the side wall of the lifting plate 9. A second slider 15 is slidably connected to the outer wall of the second guide rail 14. Two symmetrically arranged fixing blocks 18 are fixedly connected to the outer wall of the second slider 15. The fixing blocks 18 connect a guide rod 19 and the second slider 15, allowing the guide rod 19 to move synchronously with the second slider 15. A guide rod 19 is fixedly connected to the top of each fixing block 18, restricting the movement direction of the fixing block 18 and the second slider 15 to prevent deviation. The outer wall of the lifting plate 9 is fixed... The fixed connection has two L-shaped blocks 20, and two guide rods 19 pass through the corresponding L-shaped blocks 20 and are slidably connected to them. Each guide rod 19 has a spring 21 sleeved on its outer wall. When the guide rod 19 slides, the spring 21 deforms and uses elastic force to keep the first probe 17 tightly inserted with the product. The two ends of each spring 21 are fixedly connected to the fixed block 18 and the L-shaped block 20, respectively. The displacement sensor 16 is fixedly connected to the side wall of the second slider 15. The side wall of the second slider 15 is fixedly connected to a reference pressure head 22. When the reference pressure head 22 contacts the product, it provides a reference position to assist the first probe 17 in accurately aligning the interface. The bottom of the reference pressure head 22 is fixedly connected to the first probe 17.

[0025] The top of the base 1 is equipped with a detection mechanism, which includes a first mounting plate 23 fixedly connected to the top of the base 1. A second cylinder 24 is fixedly connected to the top of the first mounting plate 23. The second cylinder 24 drives the probe seat 25 and the second probe 26 to move, so as to achieve contact or separation with the product PIN pin. The output end of the second cylinder 24 is fixedly connected to the probe seat 25. The end of the probe seat 25 away from the second cylinder 24 is fixedly connected to the second probe 26. The second probe 26 is inserted into the product PIN pin, and conducts the test circuit to detect electrical performance. The two columns 2 are jointly equipped with a marking mechanism, which includes a support plate 27 fixedly connected to the two columns 2. A third cylinder 28 is fixedly connected to the top of the support plate 27. The third cylinder 28 drives the pen clamping block 29 and the marker pen 30 to move to achieve the marking action. The output end of the third cylinder 28 is fixedly connected to the pen clamping block 29. The marker pen 30 is installed on the pen clamping block 29. The marker pen 30 marks the surface of qualified products to facilitate the distinction between qualified and unqualified products.

[0026] In this invention, during operation, the thermostat is manually placed on the fixture plate 4, and the first cylinder 7 is activated. The retraction of the output end of the first cylinder 7 drives the connecting plate 8, lifting plate 9, pressure plate 12, and multiple pressure heads 13 to press the product down (the cooperation of the first guide rail 10 and the first slider 11 ensures stable lifting). During this process, the first probe 17 engages with the product. When the first probe 17 contacts the product, the second slider 15, two fixing blocks 18, and guide rod 19 slide on the L-shaped block 20. During this process, the spring 21 is compressed, and... The elastic force of spring 21 ensures that the first probe 17 is firmly inserted into the product (the first probe 17 is inserted into the product first, and then the product is pressed down by multiple pressure heads 13); the second cylinder 24 is started, and the output end of the second cylinder 24 drives the probe seat 25 and the second probe 26 to be inserted into the PIN pin of the product. Then the power is turned on to start testing the temperature controller; after the test is completed, if the test is qualified, the third cylinder 28 drives the marker pen 30 to mark the qualified product and the product is manually removed. If the product is unqualified, it is manually removed and placed in the unqualified product box (NG box).
