[0020] Example 1
[0021] In order to solve the problem of inconvenient installation of airtight test pieces in the prior art, the utility model provides an efficient airtight test device, which improves the installation convenience and test efficiency of the airtight test piece by arranging a movable clamping device in the airtight test device.
[0022] like Figures 1 to 3 As shown, the efficient airtight test device of this embodiment includes: a test bench 1, a water tank 2, a slide rail 3 and a clamping assembly 4; wherein, the water tank 2 is arranged at the bottom of the test bench 1, the slide rail 3 is arranged above the water tank 2, the test bench 1 is provided with an opening, and the slide rail 3 is arranged close to the opening; the clamping assembly 4 is arranged on the slide rail 3, and the clamping assembly 4 includes: a sliding base 41, a fixed jaw 42, a movable jaw 43 and a screw rod 44; the sliding base 41 is slidably connected to the slide rail 3, the fixed jaw 42 and the movable jaw 43 are arranged opposite to each other, the fixed jaw 42 is fixedly connected to the sliding base 41, and the movable jaw 43 is slidably connected to the sliding base 41; the screw rod 44 rotates to connect the fixed jaw 42 and the movable jaw 43 respectively, so as to drive the movable jaw 43 to approach or move away from the fixed jaw 42 along the axial direction of the screw rod 44; the airtight test piece joint 10 is clamped between the fixed jaw 42 and the movable jaw 43.
[0023] In an optional embodiment, the test bench 1 includes: a crossbeam, a longitudinal beam and a curved beam, and a plurality of crossbeams, a plurality of longitudinal beams and a plurality of curved beams are connected to each other, wherein the plurality of curved beams are spaced apart and arranged on one side of the test bench 1.
[0024] Exemplarily, the test bench 1 is composed of several overlapping horizontal beams, longitudinal beams, and curved beams. The outer surface of the test bench 1 is covered with a skin, and an opening is provided on one side of the skin to facilitate operator access to the clamping assembly 4. A water tank 2 is located at the bottom of the test bench 1 and is filled with a liquid, such as water or oil. During the airtightness test, one end of the airtightness test piece is placed in the liquid within the water tank 2. As will be appreciated, both the interior and exterior of the water tank 2 are sealed and waterproof to prevent leakage of the internal liquid.
[0025] In an optional embodiment, a handle 45 is provided at one end of the screw rod 44 of the clamping assembly 4 , and the screw rod 44 is rotated by rotating the handle 45 , thereby pushing the movable jaw 43 to move, thereby clamping or releasing the airtight test piece joint 10 .
[0026] Illustratively, the inner surfaces of the fixed jaw 42 and the movable jaw 43 are provided with anti-slip grooves and bonded with rubber gaskets 46 to increase the stability of the clamping and protect the clamped surface of the airtight test piece joint 10 .
[0027] In an optional embodiment, the axial direction of the screw rod 44 is perpendicular to the extension direction of the slide rail 3; in other words, the movement direction of the movable jaw 43 is perpendicular to the movement direction of the sliding base 41, thereby improving the clamping reliability of the clamping assembly 4 and avoiding the loosening of the movable jaw 43 due to the sliding of the sliding base 41.
[0028] In an optional embodiment, the efficient airtightness test device further includes: a slide rail clamp 5; the slide rail clamp 5 is arranged on one side of the sliding base 41; the slide rail clamp 5 is respectively connected to the sliding base 41 and the slide rail 3, and is used to lock the sliding base 41.
[0029] Preferably, the slide rail clamp 5 is driven by air pressure and remains normally open.
[0030] The working principle of the efficient airtight test device in this embodiment is that the clamping assembly 4 is installed on the slide rail 3 through the sliding base 41. Through the cooperation between the sliding base 41 and the slide rail 3, the clamping assembly 4 as a whole can move along the laying direction of the slide rail 3 in the test bench 1. The laying direction of the slide rail 3 makes it convenient for the operator to move the airtight test piece to the edge position of the test device, and transfer it to the outside of the test device through the opening, or transfer it from the outside of the test device to the test operation position. The fixed jaw 42 and the movable jaw 43 are both provided on the sliding base 41 and move together with the sliding base 41. The screw 44 is rotated by rotating the handle 45, thereby pushing the movable jaw 43 to move, thereby clamping the airtight test piece joint 10; the clamping distance between the fixed jaw 42 and the movable jaw 43 can be adjusted according to the size of the airtight test piece joint 10, thereby improving the applicability of the clamping.
[0031] When installing the airtight test piece, the clamping assembly 4 is moved out of the test operation position in the test bench 1 so that the operator can easily access and fix the airtight test piece. After the airtight test piece is fixed, the clamping assembly 4 can also be easily pushed back to the test operation position to perform an airtight test. In order to prevent the clamping assembly 4 from moving during the test, a slide rail clamp 5 is provided at the bottom of the sliding base 41. The slide rail clamp 5 is pneumatically driven and remains in a normally open state. The clamping assembly 4 can be moved inside the test bench 1 through the slide rail 3. Only when locking is required, by pressing the button switch, the air is extracted and the slide rail 3 is clamped, thereby locking the sliding base 41 to the slide rail 3, ensuring that the position of the sliding base 41 remains unchanged and improving stability.
[0032] Specifically, before the test, the rail clamp 5 remains open. The operator moves the clamp assembly 4 along the rail 3 to the open position of the test device to facilitate installation. The operator then rotates the handle 45 to push the movable jaw 43 to clamp the airtight test piece joint 10. After the clamp is firmly secured, the operator moves the clamp assembly 4 along the rail 3 back to the test operating position. The rail clamp 5 locks the sliding base 41 to maintain stability during the test. Finally, the airtight test piece can be placed in the water tank 2 for airtightness testing.
[0033] In an optional embodiment, both the clamping assembly 4 and the slide rail 3 can be electrically driven, that is, clamping and movement are achieved electrically to further reduce manual intervention and improve test efficiency.
[0034] It is worth noting that since the clamping assembly 4 can be moved to the installation position before the airtightness test and returned to the test operation position during the test, it can avoid interference with the operator during the test. The operating space of the entire test device has been optimized, simplifying the installation process of the airtightness test piece, improving the flexibility and convenience of the test, and ultimately improving the test efficiency.
[0035] It should be noted that the efficient airtight test device of this embodiment can set different lengths of the slide rail 3 according to the test requirements of the airtight test piece, and set the shape of the clamping position of the fixed jaw 42 and the movable jaw 43 according to the structure of the airtight test piece joint 10; in addition, it can also be adjusted and optimized according to the space of the laboratory and the needs of the operator.
[0036] The utility model is a highly efficient airtight test device that uses a screw to push the movable jaws to move closer to or away from the fixed jaws, thereby clamping and loosening the joints of the airtight test piece, making the installation of the airtight test piece more convenient and quick. The clamping assembly can slide along the slide rail, and the operator can move the airtight test piece along the slide rail to the opening position of the test device and transfer it to the outside of the test device, or move the airtight test piece to the test operation position. The sliding of the slide rail provides the operator with sufficient operating and installation space, and prevents the clamping assembly from obstructing the operation during the test, thereby optimizing the operating space of the entire test device, allowing the airtight test to be carried out more accurately, thereby improving the test efficiency and reducing manpower and time costs.
