s5: automatic marking, the lift seat 52 rises and drives the overlap block 94 to rise at the same time, when the overlap block 94 contacts and extrudes with the conduction rod 93, the conduction rod 93 moves horizontally, so that the elastic potential energy stored by the trigger spring 97 is released, the first piston 83 and the second piston 86 are driven to slide, and the seal 88 automatically marks the unqualified rubber ring 34.
The working principle is as follows: during operation, after the clamping groove 37 in the mounting seat 33 is aligned with the clamping block 36 on the surface of the rotating shaft 32, the mounting seat 33 is inserted into the surface of the rotating shaft 32, so that under the action of the clamping block 36 and the clamping groove 37, relative rotation between the mounting seat 33 and the rotating shaft 32 can be prevented, and the conductivity of kinetic energy of the driving motor 31 can be improved; then, the gasket 41 is sleeved outside the rotating shaft 32, the gasket 41 is positioned on one side of the mounting seat 33, then the screw cap 43 is sleeved outside the threaded rod 42, then the screw cap 43 is rotated, so that the mounting seat 33 is firmly fixed outside the rotating shaft 32, and then the rubber ring 34 (the rubber ring 34 is a rubber sealing element) is sleeved in the groove on the surface of the mounting seat 33, because the rubber ring 34 has certain elasticity, and the inner side wall of the groove of the mounting seat 33 is made of a material with a large dynamic friction factor, the rubber ring 34 can be rapidly mounted; if the rubber ring inspection 34 with different sizes needs to be tested, only the mounting seats 33 with different sizes need to be replaced, so that the device has higher flexibility when being used; based on the above further, the air cylinder 53 is started, the thrust output by the air cylinder 53 is set as the critical value of the pressure which can be borne by the qualified rubber ring 34, the air cylinder 53 pushes the lifting seat 52 to vertically rise along the inside of the shell 51, so as to drive the pressing sleeve 54 at the top of the lifting seat 52 to vertically rise, the pressing sleeve 54 can contact and press the rubber ring 34, then the driving motor 31 is started, the thrust output by the air cylinder 53 is unchanged, the driving motor 31 drives the rotating shaft 32 at the output end to rotate, so as to drive the mounting seat 33 and the rubber ring 34 on the surface of the mounting seat 33 to rotate, so that the pressing sleeve 54 and the rubber ring 34 are rotationally pressed, and after the rubber ring 34 rotates for one circle, the pressure test of a single rubber ring 34 is completed, by the method, the pressing sleeve 54 can perform omnibearing pressing on the rubber ring 34, and the phenomenon of local missing detection of the rubber ring 34 is avoided; the rubber ring 34 which is qualified in the test can not be abnormal when rotating, and can be directly taken down after the test is finished, when the local pressure test of the rubber ring 34 is unqualified, the local pressure bearing capacity of the rubber ring 34 is weaker, and the pressure exerted by the air cylinder 53 is unchanged, so that the unqualified position of the rubber ring 34 can be extruded to be seriously deformed, and the lifting seat 52 can also continuously and vertically ascend; based on the above, since the pressing sleeve 54 is rotatably mounted between the two fixing plates 61 through the rotating shaft 62, the rubber ring 34 rotates while the pressing sleeve 54 is rotated, so that the friction force of the pressing sleeve 54 on the rubber ring 34 can be reduced, thereby further preventing the rubber ring 34 from sliding relative to the mounting seat 33; based on the above, the lifting seat 52 is lifted, and simultaneously drives the second conductive sheet 71 to lift, when the second conductive sheet 71 is contacted with the first conductive sheet 7, the internal circuit of the device is conducted, and at this time, the alarm lamp 74 is turned on, so that the worker can be timely reminded that the rubber ring 34 in the test is an unqualified product; the buffer spring 73 can buffer the acting force applied when the first conducting plate 7 contacts with the second conducting plate 71; the extrusion degree of the rubber ring 34 can be visually seen through the graduated scale 75, so that the unqualified condition of the rubber ring 34 can be preliminarily judged; based on the above, the lifting seat 52 ascends to drive the overlap block 94 to ascend, when the overlap block 94 contacts and presses one end of the conducting rod 93, the conducting rod 93 moves horizontally, the rebound spring 95 is stretched, the limiting effect of the other end of the conducting rod 93 on the wedge block 92 is relieved, at this time, the elastic potential energy stored in the trigger spring 97 is released, the first piston 83 slides upwards along the inner wall of the air storage cavity 81, the air in the air storage cavity 81 is compressed, the air in the air storage cavity 81 enters the sliding sleeve 85 through the conduit 84, the second piston 86 and the sliding rod 87 slide downwards along the inner wall of the sliding sleeve 85, the stamp 88 covers the surface of the rubber ring 34, therefore, a 'unqualified' stamp appears on the surface of the rubber ring 34, and the opposite surface of the 'unqualified' stamp is the position for the pressure test of the rubber ring 34; the protection spring 89 can buffer the counterforce of the rubber ring 34 when the stamp 88 moves downwards, so that the stamp 88 can be prevented from being damaged, and the service life of the stamp 88 is prolonged; based on the above, after the test is completed, the driving rod of the cylinder 53 is contracted, the lifting seat 52 moves down, the worker pulls the pressing rod 96, the pressing rod 96 drives the connecting rod 91, the first piston 83 and the wedge block 92 to move down, the first piston 83 moves down, and the second piston 86 and the stamp 88 can be driven to move up, so that the stamp 88 is reset; when the wedge block 92 moves down to a certain position, the wedge block can contact and extrude the conducting rod 93, and after the extrusion is finished, the conducting rod 93 can automatically reset under the action of the rebound spring 95, so that the wedge block 92 is clamped to prepare for next test.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
