Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 3, a vacuum box life tester may include a case 1, a table 2, a clamping mechanism, a cover opening and closing mechanism, a key mechanism, and the like. The case 1 can be formed by welding metal plates and profiles. The bottom of the cabinet 1 is provided with casters 11 to facilitate movement. An electric cabinet and an industrial control computer are arranged in the case 1 to control the clamping mechanism, the cover opening and closing mechanism and the key mechanism to act according to a preset program, so that the service life test of the vacuum box 100 is completed. The top of the chassis 1 includes a front angled portion 12 and a rear flat portion 13. The rear flat portion 13 is much larger than the front inclined portion 12. The front inclined portion 12 is provided with an operation panel of the testing machine for convenience of operation. The operation panel is provided with an instrument, an indicator light, a key, a touch screen and the like.

The table 2 is flush-mounted on the rear flat portion 13 of the cabinet 1. The worktable 2 is provided with a plurality of locking grooves 21 extending left and right to facilitate the fixed installation of the clamping mechanism, the cover opening and closing mechanism and the key mechanism on the worktable 2 and adjust the position of each mechanism according to the specification of the vacuum box 100 to be tested.

The clamping mechanism is used for clamping the vacuum box 100 to be tested placed on the worktable 2 from the periphery. Specifically, the clamping mechanism comprises 2 front clamping cylinders 31, a rear block 32, 1 left clamping cylinder 33 and a right block 34, wherein the front clamping cylinders 31 and the rear block 32 are respectively positioned at the front side and the rear side of the vacuum box 100 to be tested so as to clamp the vacuum box 100 to be tested from the front-rear direction, and the left clamping cylinders 33 and the right block 34 are positioned at the left side and the right side of the vacuum box 100 to be tested. The rear stopper 32 and the right stopper 33 have substantially the same length and width as those of the vacuum box 100 to be tested, respectively. It should be understood that the positions of the clamping cylinder and the stop can be interchanged. Accordingly, the number and mounting positions of the front and

left clamp cylinders

31 and 33 may also be set as desired. In order to avoid the damage to the surface of the vacuum box 100 to be tested caused by the hard contact between the telescopic rods of the

clamping cylinders

31 and 33 and the vacuum box 100 to be tested, the tail ends of the telescopic rods are sleeved with rubber pads. During working, firstly, the vacuum box 100 to be tested is placed on the workbench 2, so that the vacuum box 100 to be tested is respectively close to the rear stop block 32 and the right stop block 34, then the front clamping cylinder 31 and the left clamping cylinder 33 act, and the telescopic rods of the front clamping cylinder and the left clamping cylinder extend out, so that the vacuum box 100 to be tested is clamped and positioned.

The opening and closing cover mechanism is used to open and close the vacuum cartridge 100 to be tested. Specifically, the lid opening and closing mechanism includes a lid opening key depression cylinder 41, a lid opening and closing assembly 42, and a lid closing cylinder 43. The uncovering key pressing cylinder 41 is fixedly installed on the workbench 2, is located on the right side of the vacuum box 100 to be tested, and is used for pressing a right uncovering key of the vacuum box 100 to be tested. The cover opening and closing assembly 42 is arranged on the left side and the right side of the vacuum box 100 to be tested, each side of the cover opening and closing assembly comprises a rotating arm 421 and a clamping cylinder 422, the rotating arm 421 is in driving connection with an output shaft of a motor (not shown) and can rotate back and forth, the clamping cylinder 422 is fixed on the rotating arm 421 and is used for clamping the box cover 101 of the vacuum box 100 to be tested, the cover closing cylinder 43 is arranged above the vacuum box 100 to be tested, and a telescopic rod of the cover closing cylinder moves downwards to close the box cover 101. When the vacuum box 100 is to be opened, the cover opening key pressing cylinder 41 presses the cover opening key of the vacuum box 100 to be tested to enable the box cover 101 to be separated from the buckling position, then the clamping cylinder 422 acts to clamp the box cover 101 from the left side and the right side, and then the rotating arm 421 rotates backwards to open the box cover 101; when the cover is closed, the rotating arm 421 rotates forward to return the cover 101 to the cover closing position, and finally the cover closing cylinder 43 acts to press the cover 101 downward to enter the buckling position for clamping.

In the present embodiment, the number of the closing cylinder 43 is 2, which is fixed to the cross beam of the portal frame. This is advantageous to make both ends of the box cover 101 smoothly enter the fastening positions to be fastened. Similarly, the end of the expansion rod of each cylinder of the cover opening and closing mechanism is also sleeved with a rubber pad to avoid damaging the outer surface of the vacuum box 100 to be tested.

The key mechanism is used to press each function key on the test vacuum cartridge 100. Specifically, the key mechanism includes a mounting bracket 51 and a plurality of pressing cylinders 52 mounted on the mounting bracket 51. The mounting bracket 51 is in a door shape, and spans the left side and the right side of the vacuum box 100 to be tested, and the plurality of pressing cylinders 52 are arranged in a line on a cross beam of the mounting bracket 51 and positioned above the vacuum box 100 to be tested. The plurality of pressing cylinders 52 correspond to the function keys on the vacuum box 100 one by one. When that function is to be tested, the corresponding push cylinder 52 is actuated. Similarly, the end of the expansion link of each cylinder of the key mechanism is also sleeved with a rubber pad to avoid damaging the function keys of the vacuum box 100 to be tested.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
