[0033] In this embodiment, preferably, the front end of the third longitudinal rotating shaft 48 passes through and extends to the front side of the machine base 1, and the front end of the third longitudinal rotating shaft 48 is fixedly connected with a knob 410, and the outer ring of the knob 410 is provided with anti-slip grooves; the knob 410 with anti-slip grooves can facilitate the control of the rotation of the third longitudinal rotating shaft 48.

[0034] The working principle and use process of this utility model:

[0035] First, according to the size of the sealing rubber material to be tested, the second motor 32 is turned on to drive the second bidirectional screw 31 to rotate, so that the connecting block 33 drives the mechanical clamping jaws 2 to move away from each other to adapt to the size of the sealing rubber material to be tested;

[0036] Secondly, the sealing rubber material to be tested is placed between the two T-shaped seats 21, and the first motor 28 is turned on to drive the first worm 29 to rotate, so that the first worm wheel 210 drives the second longitudinal rotating shaft 24 to rotate, and the second gear 27 rotates with the second longitudinal rotating shaft 24 and drives the first gear 25 to rotate. When the first gear 25 rotates, it drives the second longitudinal rotating shaft 24 to rotate and causes the clamping arm 26 to deflect for clamping. The clamping block 211 moves with the clamping arm 26 and can deflect to contact the sealing rubber material to be tested, and cooperates with the tooth-shaped anti-slip protrusion 212 to clamp the sealing rubber material to be tested. Compared with the prior art, the clamping effect is better;

[0037] Then, the control knob 410 causes the third longitudinal rotating shaft 48 to drive the first bevel gear 49 to rotate, and the second bevel gear 47 meshing with the first bevel gear 49 rotates accordingly and drives the second worm 46 to rotate, and the second worm 46 cooperates with the second worm wheel 45 to rotate the first bidirectional screw 41, and the first bidirectional screw 41 rotates to cause the moving block 42 to drive the spring 7 to move, so that the spring 7 is in a natural state and one end away from the moving block 42 contacts the annular pressure sensor 6, and the annular pressure sensor 6 can be connected to the PLC control display terminal (not shown) through a wire, and the PLC control display terminal can be a separate device, and can also be installed on the machine base 1 for use;

[0038] Finally, the second motor 32 drives the second bidirectional screw 31 to rotate, so that the connecting block 33 drives the mechanical clamps 2 to move away from each other and apply tension to the sealing rubber material to be tested. At the same time, the connecting plate 5 follows and drives the annular pressure sensor 6 to move. Due to the squeezing of the spring 7, the spring 7 generates pressure on the annular pressure sensor 6. The annular pressure sensor 6 inputs the pressure signal to the PLC control display terminal in time, and can display the pressure value of the annular pressure sensor 6 in real time, thereby facilitating the real-time recording of the tension value of the sealing rubber material.

[0039] In summary, the utility model clamps the sealing rubber material to be tested by mechanical claws, so the clamping effect is improved, and the pressure value of the annular pressure sensor can be displayed in real time during the tension detection process, thereby facilitating real-time recording of the tension value of the sealing rubber material.
