However, when the telescopic rod 503 rotates clockwise, the two torsion springs 505 at the first end of the telescopic rod 503 are twisted to store force, and when the telescopic rod 503 is not limited, the torsion springs 505 drive the telescopic rod 503 to reset.
Working principle: the flowmeter shell to be tested is firstly conveyed to the conveying support block 106 of the device through external conveying equipment, then the motor 101 is started, power is conveyed to the transmission shaft 103 and the conveying rotating wheel 104 through the belt 102, the conveying conveyor belt 105 is driven to rotate, the conveying support block 106 is controlled to move, the conveying support block 106 drives the shell to move downwards, the shell is close to the transverse moving support block 203, when the conveying conveyor belt 105 rotates, the conveying conveyor belt 105 also drives the transverse moving rotating wheel 201 to rotate, the transverse moving support block 203 is controlled by the transverse moving conveyor belt 202 to move along with the transverse moving support block 202 through the transverse moving rotating wheel 201, the transverse moving support block 203 can push the left push rod 306 to rotate around the axis of the vertical transmission shaft 305 in a certain distance before the transverse moving support block 203 moves to the shell, the vertical transmission shaft 305 is driven to rotate, the vertical transmission shaft 305 is controlled to move through the upper rotary table 301, the push rods 401 are driven to push the push rods 402 to move, the push rods 402 are driven to push the sealing covers 403 to be attached to the pipe openings on two sides of the shell, the pipe openings are sealed through the sealing covers 403, and if the color gas in the inflating bin 406 is inflated into the shell, if the color gas is insufficient, whether leakage exists in the water tank 604 can be judged through observing whether the leakage exists or not.
And when the sealing cover 403 moves towards the shell, the supporting connecting rod 410 is driven to slide on the sliding frame 404, so that after the supporting connecting rod 410 contacts with the inclined plane on the limiting rod 407, the limiting rod 407 is pushed to slide upwards on the sliding frame 404 and compress the limiting spring 408, when the supporting connecting rod 410 leaves the limiting rod 407 and is no longer contacted with the limiting rod 407, the limiting rod 407 is reset under the action of the limiting spring 408, and at the moment, the sealing cover 403 also seals the orifice of the shell, namely the sealing cover 403 stops moving, so that the supporting connecting rod 410 and the sliding connecting rod 409 also stop moving, the limiting rod 407 is positioned between the supporting connecting rod 410 and the sliding connecting rod 409, and the sealing cover 403 is limited to move, so that the orifice of the shell can be firmly plugged by the sealing cover 403, and further, the sealing covers 403 on two sides are prevented from being pushed out due to overlarge pressure inside the shell, and test failure is caused.
The traversing conveyor 202 and the traversing supporting block 203 are controlled to move continuously through the rotation of the traversing rotating wheel 201, so as to push the shell, and the shell drives the sealing cover 403 to move along with the shell, so that the push rod 402 slides on the push frame 401, and the supporting connecting rod 410 and the sliding connecting rod 409 slide on two sides of the sliding frame 404 respectively. In the moving process, the inside of the shell is continuously pressurized through the inflating bin 406 and the inflating tube 405, the sealing performance and the compression resistance of the shell are tested, when the supporting connecting rod 410 moves to the opening at the right end of the sliding frame 404, the test is finished, the pressurization is stopped or the pressurization can be stopped before the supporting connecting rod reaches according to the test requirement, and in the position, the supporting connecting rod 410 is not supported by the sliding frame 404, and under the action of the pressure in the shell, the sealing cover 403 can be pushed out, so that the supporting connecting rod 410 and the pushing rod 402 are driven to move towards the pushing frame 401.
When the shell moves to the right, the sliding cylinder 501 is driven to move to the right through the sliding connecting rod 409 and the push rod 402, so that the swivel 502 is driven to rotate clockwise, the telescopic rod 503 is compressed, the telescopic spring 504 on the telescopic rod 503 and the torsion spring 505 on the torsion telescopic rod 503 are compressed, and the subsequent resetting of the sealing cover 403 is facilitated.
In the process that the sealing cover 403 and the shell move towards the position of the opening on the right side of the sliding frame 404, in the fast approaching place, as a plurality of transverse moving supporting blocks 203 are arranged on the transverse moving conveyor belt 202, the transverse moving supporting blocks 203 moving towards the left side of the sliding frame 404 after the previous test is finished push the push rods 307, so that the push rods 307 drive the vertical transmission shafts 305 to rotate, the vertical transmission shafts 305 drive the upper turntable 301 to rotate, the upper turntable 301 drives the lower turntable 302 to rotate, and the transmission belts 303 drive the upper turntable 301 and the lower turntable 302 on the left side of the sliding frame 404 to rotate, so that push frames 401 on two sides of the shell are controlled to move towards the direction far away from the shell, and when the sealing covers 403 on two sides cannot be completely moved out due to insufficient internal pressure of the shell, the push rods 402 are pulled by the push frames 401, and the push rods 402 are pulled away from the pipe orifices of the shell by the sealing covers 403.
After the sealing cover 403 is separated from the pipe orifice of the casing, under the action of the torsion spring 505, the telescopic rod 503 rotates anticlockwise, the rotating ring 502 and the sliding cylinder 501 drive the sealing cover 403 and other parts to return to the left side of the sliding frame 404, and under the action of the telescopic spring 504, the telescopic rod 503 firstly contracts and extends, so that the sealing cover 403 and other parts return to the initial position.
When the sealing cover 403 leaves the shell, the transverse moving supporting block 203 is tied to the axle center of the conveying supporting block 106 on the right side of the sliding frame 404, so that when the transverse moving rotating wheel 201 continues to rotate, the transverse moving supporting block 203 is driven to move rightwards by the transverse moving conveying belt 202, the conveying supporting block 106 and the shell are driven to move upwards by the conveying belt 105, the shell breaks away from the transverse moving supporting block 203, leaves a test area under the action of the conveying supporting block 106, and ends the test, and then is collected and stored by an external device.
In the test process, the water tank 604 is filled with water, when the tightness of the shell is insufficient or the pressure resistance is insufficient, the colored gas filled into the shell leaks, bubbles and colors can appear in the water, so that whether the leakage occurs at the position can be obviously observed, and further a test conclusion can be obtained. After the test or the test, the water in the water tank 604 can be filtered and replaced by the filter box 602, so that the test is prevented from being influenced by the problem of water quality.
