[0017] A test method of a battery tank performance tester, comprising the following steps:

[0018] Step one: by inserting the tank into the top groove formed in the top of the double circular plate, then rotating the thrust handle downward, so that the first extension shaft connected with the center part will be counterclockwise deflected, at the same time, the first double-head plate fixedly connected to the outer side of the first extension shaft will be counterclockwise deflected and extruded to the pressure plug rod. The inner end of the first extension shaft is connected with the center shaft, the other end of the center shaft is connected with the second extension shaft, the outer side of the second extension shaft is connected with the second double-head plate, so the second double-head plate will be counterclockwise deflected and extruded to the pressure plug rod on the other side of the double circular plate. The bottom of the head of the first double-head plate is extruded to the pressure plug rod on the same side, and the top of the head of the second double-head plate is extruded to the pressure plug rod on the same side;

The inner side of the spline groove is slidably matched with the extrusion rod, the inner end of the extrusion rod is connected with the second magnetic block, and the inner side of the spline groove is connected with the first magnetic block through the inner frame body. The two magnetic blocks maintain an attractive relationship, so that when the gas is compressed, the extrusion rod will take the second magnetic block away from the first magnetic block and extend outward until the clamping piece is extruded. Finally, the clamping piece will move towards the center of the top groove and achieve clamping of the tank.

[0020] Step three: the downward deflection of the thrust handle in the counterclockwise direction causes the triangular plate originally pressed by the top to move towards the double circular plate under the compression of the return spring, wherein the triangular plate is connected with the return spring through the compensation block, and the surface of the compensation block is fixedly connected with the penetrating rod, so that the penetrating rod penetrates through the surface of the clamping piece and the groove piece under the compression of the return spring, so as to achieve the reinforcing and limiting treatment of the groove piece. When the bottom of the groove piece is clamped, the motor is started, so that the lead screw connected with the output end through the shaft coupling rotates, and the sliding block connected with the lead screw threadedly moves upwards with the center table, until the top of the groove piece contacts with another tension-compression mechanism installed on the bottom of the middle support plate, and the same method is used to clamp the top of the groove piece. Then the reverse rotation of the motor causes the center table to move downwards to detect the tensile test of the groove piece, and the forward rotation of the motor causes the center table to move upwards to detect the compressive test of the groove piece;

[0021] Step four: the electric push rod is also started, so that the toothed plate moves forward with the rack connected with the telescopic end, and the other side of the rack is in meshing transmission with the gear, and the gear is fixedly connected to the outer side of the circular seat, so that the circular seat rotates, wherein the top of the circular seat is fitted with the adapter, that is, the fitting and adaptation between the teeth, so that the adapter moves with the double circular plate, and the bottom of the groove piece rotates to detect the torsional test of the groove piece itself;

[0022] Step five: the plug-in strip is manually pushed rightwards, so that the plug-in strip moves rightwards along the inside of the hollow plate, and the other end of the plug-in strip is sleeved on the adapter stem, wherein the plug-in strip is in meshing connection with the adapter stem, so that the plug-in strip drives the adapter stem to deflect counterclockwise, and the fixed strip fixedly connected to the outer side of the adapter stem deflects counterclockwise with the adapter stem as the center, to detect the tangential force test of the surface of the groove piece.

[0023] Compared with the prior art, the beneficial effects of the present application are:

[0024] 1. The two magnetic blocks are moved away from the first magnetic block by the extrusion rod, and extend outward until the clamping piece is extruded, and finally the clamping piece moves towards the center of the top groove, thereby achieving the complete clamping of the two sides of the groove piece.

[0025] 2. The penetrating rod penetrates through the surface of the clamping piece and the groove piece, thereby preventing the groove piece from falling off during the torsional test due to the fact that the torsional force is greater than the clamping force, and achieving the effect of preventing the test from failing.

[0026] 3. By reversing the motor, the center platform moves downward, thereby playing a role in tension test detection of the groove piece. Similarly, by rotating the motor, the center platform moves upward, thereby playing a role in pressure test detection of the groove piece.

[0027] 4. By rotating the bottom of the groove piece, the top of the groove piece remains stationary, thereby playing a role in torsion test detection of the groove piece itself. In addition, it also plays a role in multiple test processing of the groove piece itself by applying torsion force while performing pressure test or tension test on the groove piece.

[0028] 5. By fixing the fixed bar connected to the outside of the adapter stem, the fixed bar will be deflected counterclockwise with the adapter stem as the center, thereby playing a role in transverse shear test detection of the center part of the groove piece. BRIEF DESCRIPTION OF DRAWINGS
