Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 The oil cooler semi-finished product pressure testing device offers two technical solutions:

[0024] The first embodiment includes a workbench 1 and multiple air pumping components 2. A lifting component 5 is provided above the workbench 1. The multiple air pumping components 2 are installed on the lifting component 5 and can move up and down through the lifting component 5. The air pumping components 2 are connected to an external air pump. An electromagnetic switch valve is provided on the air supply pipe 21 and is controlled by a push switch 35. When the push switch 35 is pressed, the electromagnetic valve opens and when the press is released, the electromagnetic valve closes. The bottom of the air pumping components 2 is fixedly connected to the air supply pipe 21 and the air return pipe 22. A switch component 3 is provided outside the air supply pipe 21. An adjustable clamping component 4 is provided above the workbench 1 to clamp the oil cooler and the clamping position can be adjusted.

[0025] The switch assembly 3 includes two sliders 31, one on the left and one on the right. Both sliders 31 are fixedly connected to the surface of the slider 31. A pressure sleeve 32 is slidably connected to the surface of the air supply pipe 21. A pressure plate 33 is fixedly connected to the surface of the pressure sleeve 32. A return spring 34 is fixedly connected to the top of the pressure sleeve 32. A push switch 35 is fixedly connected to the bottom of the air pump assembly 2, and the push switch 35 is located directly above the pressure plate 33. Two lead screws 36 are fixedly connected to the bottom of the air pump assembly 2. The pressure sleeve 32 is sleeved on the surface of the lead screws 36. Adjusting nuts 37 are threadedly connected to the surfaces of the two lead screws 36, and the adjusting nuts 37 are in contact with the bottom of the pressure sleeve 32.

[0026] When the oil cooler is pressure tested, the air pump assembly 2 moves downward and contacts the air inlet pipe of the oil cooler through the pressure sleeve 32. After being pressed down to the position, the pressure plate 33 contacts the press switch 35, thus starting automatic inflation without the need for separate control, which greatly improves the working efficiency of the device.

[0027] The second embodiment differs from the first embodiment in that: the adjustable clamping assembly 4 includes two fixed seats 41 on the left and right, which are fixedly connected to the top of the worktable 1. A fixed rod 42 is fixedly connected between the two fixed seats 41. Multiple pressure blocks 43 are equidistantly mounted on the surface of the fixed rod 42. Guide groove blocks 44 are fixedly connected to the back of each of the multiple pressure blocks 43. Two cylinders 45 on the left and right are fixedly connected to the bottom of the worktable 1. Push rods 46 are fixedly connected to the output ends of the two cylinders 45 located above the worktable 1. The push rods 46 are located in the guide grooves of the multiple guide groove blocks 44.

[0028] When testing the oil cooler, the adjustable clamping assembly 4 is used to press and fix its position, and the position of the pressure block 43 can be adjusted, so as to press the oil cooler in a suitable position and thus be applicable to oil coolers of different shapes.

[0029] In use, place the oil cooler above the workbench 1, move the pressure block 43 to a suitable position above the oil cooler, start the cylinder 45 to move the push rod 46 upward, and with the cooperation of the push rod 46 and the guide block 44, the pressure block 43 rotates, thus pressing against the top of the oil cooler. Start the lifting assembly 5 to move multiple air pumping assemblies 2 downward, so that the air supply pipe 21 enters the air inlet pipe of the oil cooler. At the same time, the pressure sleeve 32 contacts the top of the air inlet pipe and moves upward. The pressure sleeve 32 moves upward and makes the pressure plate 33 contact the press switch 35, thereby turning on the air pumping assembly 2 and pumping air into the oil cooler to start the pressure test. After the test is completed, the air pumping assembly 2 moves upward, the pressure plate 33 disengages from the press switch 35, and the air pumping is turned off.
