Description

Technical Field

[0001] This utility model relates to the technical field of automotive air conditioning assembly testing, and in particular to an experimental device for testing the stiffness of automotive air conditioning assemblies. Background Technology

[0002] The automotive air conditioning assembly is the core component of an automotive air conditioning system, encompassing the refrigeration system, heating system, ventilation and air purification devices, and control system. Different types of air conditioning systems have different layouts. Currently, passenger cars widely use integrated heating and cooling air conditioning systems, which combine the evaporator, heater core, centrifugal blower, and control mechanisms into a single assembly. The function of the automotive air conditioning assembly is to cool, heat, ventilate, and purify the air inside the vehicle, providing a comfortable riding environment, reducing travel fatigue, and ensuring safe driving. It utilizes the limited space inside the car, has a simple structure, and is easy to operate. During the manufacturing process of the automotive air conditioning assembly, rigidity testing is a crucial step.

[0003] In the prior art, patent document CN203414347U discloses a stiffness testing device, including a positioning baffle, a force transmitter I, a force transmitter II, a pressure sensor, and a digital display. The force transmission directions of force transmitter I and force transmitter II are on the same plane and perpendicular to each other. Pressure plates are provided at the ends of force transmitter I and force transmitter II. The pressure sensor is located between the pressure plates and the force transmitters, and the data from the pressure sensor is transmitted to the digital display. Two mutually perpendicular planes are provided on the inner side of the positioning baffle, corresponding to the pressure plates at the ends of force transmitter I and force transmitter II. The part to be tested is placed between the positioning baffle and the pressure plates at the ends of force transmitter I and force transmitter II.

[0004] During use, it was found that when the above-mentioned device is used for testing, a group of workpieces to be tested needs to be installed and the tested workpieces removed before another group of workpieces to be tested is placed and the stiffness test is carried out. This process of loading and unloading workpieces results in a waste of time and resources. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an experimental device for testing the stiffness of automotive air conditioning assemblies to improve testing efficiency.

[0006] This utility model discloses an automotive air conditioning assembly stiffness testing device, comprising a worktable, a first strip opening, a second strip opening, support legs, and a controller. The worktable has a first strip opening and a second strip opening. A set of support legs is located at each of the four corners of the worktable's bottom. The controller is mounted at the front of the worktable. The device also includes a loading assembly, a fixing assembly, and a stiffness testing assembly. The loading assembly is located within the first and second strip openings. Two pairs of fixing assemblies are located at the top of the worktable, with the first strip opening between one pair of fixing assemblies and the second strip opening between the other pair. The stiffness testing assembly is located at the top of the worktable. All components are electrically connected to the controller. The first group of automotive air conditioning assemblies is placed on the loading assembly, which moves it below the stiffness testing assembly. The corresponding fixing assembly is then used to fix the first group of automotive air conditioning assemblies. After that, the stiffness testing assembly is used to perform stiffness testing on the first group of automotive air conditioning assemblies. During the testing process, the second group of automotive air conditioning assemblies is placed on the loading assembly. After the testing is completed, the loading assembly is activated, thereby swapping the positions of the first and second groups of automotive air conditioning assemblies. This reduces the waste of time and resources and improves testing efficiency when loading and unloading automotive air conditioning assemblies using the stiffness testing device.

[0007] Preferably, the feeding assembly includes a first screw, a second screw, a first sprocket, a second sprocket, a chain, sliders, moving plates, rollers, placement slots, and a motor. The first screw is rotatably installed in the first strip-shaped opening, and the second screw is rotatably installed in the second strip-shaped opening. The threads of the first and second screws are opposite. The rear ends of both the first and second screws extend to the rear side of the worktable. The rear end of the first screw is equipped with a first sprocket, and the rear end of the second screw is equipped with a second sprocket. The first and second sprockets are driven by a chain. A set of sliders is slidably installed in the first and second strip-shaped openings, respectively. The first set of sliders is threadedly connected to the first screw, and the second set of sliders is threadedly connected to the second screw. A set of moving plates is installed at the top of each set of sliders, and a placement slot is installed at the top of each set of moving plates. A roller is installed at the bottom of each set of moving plates, and the rollers are in rolling contact with the top of the worktable. A motor is installed at the front end of the worktable, and the motor output is connected to the first screw. The front end of the rod is connected; the motor is started, causing the first screw to drive the first set of sliders to move forward in the first strip opening. At the same time, the first screw, through the cooperation of the first sprocket, the second sprocket, and the chain, drives the second screw to rotate synchronously, causing the second set of sliders to move backward in the second strip opening. The first set of automotive air conditioning assemblies is placed in the placement slot of the first set of moving plates. Then, the motor is operated to rotate, causing the first screw to drive the first set of sliders, the first set of moving plates, and the first set of automotive air conditioning assemblies to move backward to below the stiffness testing component. At the same time, the second set of sliders in the second strip opening drives the second set of moving plates to move forward. During the testing of the first set of automotive air conditioning assemblies, the operator places the second set of automotive air conditioning assemblies in the placement slot of the second set of moving plates. When the first set of automotive air conditioning assemblies is tested, as the first set of automotive air conditioning assemblies moves forward, the second set of automotive air conditioning assemblies moves backward to below the stiffness testing component, improving testing efficiency.

[0008] Preferably, the fixing component includes a vertical plate, a first hydraulic cylinder, and a clamping plate. The vertical plate is provided at the top of the worktable, and the first hydraulic cylinder is provided at the outer end of the vertical plate. The moving end of the first hydraulic cylinder extends to the other side of the vertical plate and is provided with a clamping plate. When it is necessary to fix the automotive air conditioning assembly, the two sets of adjacent first hydraulic cylinders are activated to extend, thereby causing the corresponding two sets of clamping plates to press and fix the automotive air conditioning assembly, preventing the automotive air conditioning assembly from moving during stiffness testing and affecting the test results.

[0009] Preferably, the stiffness detection component includes a guide bar, a top plate, an electric track, a movable seat, a second hydraulic cylinder, a pressure sensor, and a pressure plate. Two sets of guide bars are installed at the top of the worktable, with the top ends of both sets connected to the bottom of the top plate. An electric track is installed at the top of the top plate. The movable seat is fitted onto the top plate and slidably connected to the electric track. A second hydraulic cylinder is installed at the bottom of the movable seat, and a pressure sensor is installed at the bottom moving end of the second hydraulic cylinder. A pressure plate is installed at the bottom end of the pressure sensor. Based on the position of the automotive air conditioning assembly, the movable seat adjusts its position with the assistance of the electric track. When the pressure plate is above the automotive air conditioning assembly, the second hydraulic cylinder extends, causing the pressure sensor and pressure plate to descend. The pressure plate performs stiffness detection on the automotive air conditioning assembly, and the pressure sensor transmits the detected pressure value to the controller for display.

[0010] Preferably, it also includes supports, with supports provided at the bottom of the legs; the four sets of legs and the four sets of supports work together to provide stable support for the worktable.

[0011] Preferably, a reinforcing plate is provided between the worktable and the support leg; the worktable and the support leg are reinforced by the reinforcing plate to improve the connection strength.

[0012] Preferably, it also includes support blocks. Two sets of support blocks are respectively provided on both sides of the first strip opening and the second strip opening. The top of the support block contacts the bottom of the moving plate. When the moving plate supports the automotive air conditioning assembly, the pressure plate performs stiffness testing on the automotive air conditioning assembly, and the support block supports the corresponding moving plate to reduce the pressure on the rollers.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The first group of automotive air conditioning assemblies is placed on the loading component, which moves the first group of automotive air conditioning assemblies below the stiffness detection component. The corresponding fixing component is then operated to fix the first group of automotive air conditioning assemblies. After that, the stiffness detection component is operated to perform stiffness detection on the first group of automotive air conditioning assemblies. During the detection process, the second group of automotive air conditioning assemblies is placed on the loading component. After the detection is completed, the loading component is activated, thereby swapping the positions of the first group of automotive air conditioning assemblies and the second group of automotive air conditioning assemblies. Thus, when using the stiffness detection device for detection, the loading and unloading of automotive air conditioning assemblies reduces the waste of time and resources and improves the detection efficiency.
