[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Reference Figures 1-6 As shown, this utility model discloses a testing fixture for pressing an automotive air conditioning vent to solve the above-mentioned technical problems, comprising: A base plate 1, the surface of which is provided with a plurality of positioning rods 2, and the plurality of positioning rods 2 are used to place the product 4; The clamping assembly 3 includes a base 31, a clamping cylinder 32, a pressure rod 33, a first connecting rod 36, and a second connecting rod 37. The base 31 is mounted on the base plate 1, and a first support 34 is mounted on the top of the base 31. A second support 35 is mounted between the first supports 34. Safety valves 38 are mounted on both the inlet and outlet ends of the clamping cylinder 32. The fixed end of the clamping cylinder 32 is hinged to the first support 34. The two ends of the first connecting rod 36 are respectively hinged to the telescopic end of the clamping cylinder 32 and the second support 35. One end of the pressure rod 33 is hinged to the second support 35. One end of the second connecting rod 37 is hinged to the telescopic end of the clamping cylinder 32, and the other end of the second connecting rod 37 is hinged to the end of the pressure rod 33 near the second support 35. A locking platform 371 is mounted on the surface of the second connecting rod 37.

[0019] In the above structure, multiple positioning rods 2 are mounted on the base plate 1 to limit the product 4 in multiple directions. During actual operation, the multiple positioning rods 2 are engaged on the outer side (at least three sides) of the product 4 to laterally position the irregularly shaped product 4, maintaining it in the posture required for testing. The base 31 in the clamping assembly 3 supports the clamping cylinder 32 and the pressure rod 33. The base 31 and multiple positioning rods 2 are arranged around the product 4 to clamp it and fix it vertically. Specifically, the first bracket 34 supports the clamping cylinder 32, and the second bracket 35 fixes one end of the pressure rod 33. The telescopic end of the clamping cylinder 32 is hinged to the first connecting rod 36 and the second connecting rod 37. The telescopic movement of the clamping cylinder 32 drives the first connecting rod 36 and the second connecting rod 37 to rotate. The rotation of the second connecting rod 37 causes the pressure rod 33 to flip. The second connecting rod 37 is hinged to the end of the pressure rod 33 near the second bracket 35, shortening the telescopic length of the clamping cylinder 32. The surface of the second connecting rod 37 is also provided with a clamping platform 371. When pressing the product 4, the pressing cylinder 32 extends, causing the second connecting rod 37 to flip. The second connecting rod 37 then causes the pressure rod 33 to flip. After the clamping platform 371 abuts against the pressure rod 33, the second connecting rod 37 continues to move, and the clamping platform 371 squeezes the pressure rod 33, pressing the other end of the pressure rod 33 onto the product 4. During the opening action, the design of the clamping platform 371 can also avoid the flipping of the pressure rod 33, increasing the rotation angle of the pressure rod 33. The entire rotation angle (greater than 90°) provides a large operating space for loading and unloading the product 4, avoiding interference from the pressure rod 33 during the loading and unloading of the product 4. In addition, safety valves 38 are installed at the air inlet and outlet of the pressing cylinder 32 to regulate the pressure of the pressing cylinder 32 and prevent excessive pressure from damaging the product 4.

[0020] This invention achieves rapid and accurate positioning of product 4 using multiple positioning rods 2, eliminating the need for repeated positioning. Secondly, the clamping cylinder 32 controls the multi-link mechanism, enabling rapid and precise clamping of product 4, thus improving testing efficiency. The multi-link mechanism allows for large-angle rotation of the pressure rod 33, facilitating the loading and unloading of product 4. Furthermore, the clamping cylinder 32 is equipped with a safety valve 38, ensuring precise pressure control and preventing excessive pressure from damaging product 4.

[0021] Furthermore, the positioning rod 2 is installed with its axis perpendicular to the surface of the base plate 1, and the positioning rod 2 is detachably connected to the base plate 1; the surface of the base plate 1 is provided with a positioning hole 11 that cooperates with the positioning rod 2, and the positioning hole 11 is a strip-shaped hole.

[0022] Specifically, in this invention, the multiple positioning rods 2 are detachably connected to the base plate 1. The number of positioning rods 2 is selected according to the size of the product 4 to laterally position the product 4. During actual installation, the positioning rods 2 are connected to the positioning holes 11 on the base plate 1. To avoid interfering with the installation position of the product 4, the positioning rods 2 are installed perpendicular to the base plate 1, and the product 4 is directly inserted from the top of the multiple positioning rods 2. As a preferred embodiment of this invention, the positioning holes 11 are elongated holes, allowing for fine-tuning of the radial position of the positioning rods 2, so that the multiple positioning rods 2 clamp the product 4.

[0023] Furthermore, a pressure block 39 is provided at the end of the pressure rod 33 away from the second bracket 35, and a rubber pad is provided on the surface of the pressure block 39.

[0024] Specifically, the pressure block 39 is positioned between the product 4 and the pressure rod 33. The pressure block 39 is in direct contact with the product 4. The surface of the pressure block 39 is provided with a rubber pad to avoid damage to the surface of the product 4 and to ensure the quality of the product 4.

[0025] Furthermore, the surface of the pressure rod 33 is provided with an adjustment groove 331, the adjustment groove 331 is arranged along the axial direction of the pressure rod 33, and the pressure block 39 is disposed in the adjustment groove 331.

[0026] Specifically, the pressure block 39 is adjustable within the adjustment groove 331 to accommodate products 4 of different specifications and meet diverse clamping needs. In actual operation, the position of the pressure block 39 is adjusted according to the position of the product 4, and the pressure block 39 is fixed by the locking nut on the pressure block 39. As a preferred embodiment of this utility model, scale lines 332 are provided on both sides of the adjustment groove 331 to record the position of the pressure block 39. Each product 4 corresponds to one scale (type change parameter), quantifying the stroke of the pressure block 39 and ensuring the accuracy and reproducibility of the clamping position.

[0027] Furthermore, handles 5 are provided on both sides of the surface of the base plate 1, which facilitates the handling of the entire clamping fixture.

[0028] Furthermore, the surface of the base plate 1 is also provided with an identification plate 12, which can quickly identify the clamping fixtures corresponding to different products 4, thereby improving the inspection efficiency of products 4.

[0029] Furthermore, a plurality of flexible contact pads 6 are provided on the side of the base plate 1 away from the positioning rod 2. The flexible contact pads 6 support the base plate 1, which can increase the height of the base plate 1 on the one hand, and ensure the stability of the entire pressing operation on the other hand.
