Description

Technical Field

[0001] The utility model relates to a jig, in particular to a flow rate and pressure difference testing jig. Background Art

[0002] Vehicle-mounted housings are widely used in automobiles. To improve heat dissipation, a type of vehicle-mounted housing has a built-in water cooling structure that achieves cooling through water input. Before leaving the factory, it needs to be tested for the flow pressure it can withstand. Traditional testing methods require aligning the external connector with the interface of the vehicle-mounted housing, inserting it, and then passing water to check the flow pressure difference during product testing. The plug-and-pull quick-connect method is not only difficult to operate and requires a lot of time and manpower, but also due to the complexity and uncertainty of the operation, it is difficult to ensure the accuracy and stability of each plug-in and pull-out, thus failing to effectively guarantee product quality. In addition, frequent plug-in and pull-out operations can easily cause wear and tear on the product interface and quick connector, increasing the product defect rate and repair costs. Specific working steps: Pick up the product with your left hand and the test quick connector with your right hand. Align the quick connector slot with the product connector and press the connector firmly onto the product interface until it is connected. Summary of the Invention

[0021] like Figure 1 and 2 As shown, a flow pressure difference test fixture includes a base 1, wherein a positioning area 2 is provided in the base 1, and the positioning area 2 is used to place the product to be tested. A top block 3 and a cylinder 4 are provided on one side of the positioning area 2, and a water cavity is provided in the top block 3. A water inlet connector 5 and a water outlet connector 6 are provided on the top block 3. The pistons of the top block 3 and the cylinder 4 are connected. A manual valve switch 7 is provided on the base 1, and the manual valve switch 7 is connected to the cylinder 4. The manual valve switch 7 is used to start and close the cylinder 4. The cylinder 4 drives the top block 3 to move, so that the water outlet connector 6 can be directly connected to the corresponding interface of the sample to be tested, without the need for manual clamping, thereby improving accuracy and convenience. The water inlet connector is connected to an external water supply device to provide circulating water. In this embodiment, two cylinders and two top blocks are provided. The water outlet connector of one top block serves as the water inlet of the product to be tested, and the water outlet connector of the other top block serves as the water outlet of the product to be tested, thereby forming a circulating flow of water, which is convenient for testing the flow pressure difference.

[0022] The base 1 is provided with a guide groove 8, and the top block 3 is movably arranged in the guide groove 8. The top block 3 moves in the guide groove 8 with directionality, ensuring the accuracy of movement and enabling the water outlet joint to achieve precise docking with the sample to be tested.

[0023] Positioning blocks 9 are located on the sides of the positioning area 2. A stopper 10 is located at the end of the base 1 and is screwed to the base 1. These blocks ensure accurate placement of the product under test, eliminating the need for adjustment. To accommodate products of varying sizes, both the positioning block and the stopper are screwed to the base, making them easy to disassemble and install, and to adjust the size of the positioning area, thereby expanding its applicability.

[0024] The base 1 is mounted with a cylinder fixing plate 11, one side of the cylinder 4 is connected to the cylinder fixing plate 11, and the piston of the cylinder 4 passes through the cylinder fixing plate 11. The base 1 is provided with a mounting groove 12, and the bottom of the cylinder 4 is embedded in the mounting groove 12, which facilitates the installation and fixation of the cylinder 4.

[0025] The bottom surface of the base is provided with supporting feet, which can be long strips.

[0026] The base 1 includes a bottom plate 13, on which the cylinder 4, the top block 3, the guide groove 8 and the cylinder fixing plate 11 are all arranged. The bottom plate 13 is fastened to the base 1 by screws, which facilitates the disassembly of the whole.

[0027] During use, adjust the position of the positioning block and the stopper, that is, adjust the size of the positioning area according to the size of the product to be tested, and then place the product to be tested in the positioning area. The sides are blocked and tightened by the positioning block and the stopper to ensure the tightness of the product to be tested and to ensure that it will not deviate during the test. Start the cylinder to drive the push block toward the sample to be tested, so that the water outlet joint is connected to the corresponding interface of the sample to be tested, and the water inlet joint is connected to the external water supply equipment. After water supply, water enters the sample to be tested through the water outlet joint, and then is discharged from different water outlet joints and returns to the water supply equipment, circulating, facilitating the test of flow and pressure difference, simple operation, and improving test efficiency.

[0028] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
