Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1 to 15, a general sealing gasket testing device includes a frame 1, a feeding device 2, a testing rotary table 3 and a sliding table material taking mechanism 4 are arranged on the frame 1, a thickness detecting mechanism 5 is arranged at one end of the testing rotary table 3 of the frame 1, the sliding table material taking mechanism 4 can transfer a sealing gasket at the feeding device 2 onto the testing rotary table 3, and the thickness detecting mechanism 5 performs thickness detection;

the test rotating platform 3 comprises a rotating swing arm 6 and a first driving piece 7 for driving the rotating swing arm 6 to rotate, material platforms 8 for bearing sealing gaskets are movably clamped at two ends of the rotating swing arm 6, and the two material platforms 8 are respectively matched with the sliding table material taking mechanism 4 and the thickness detection mechanism 5.

In the actual operation process, the sealed pad of material feeding unit 2 department is transported to the material platform 8 of 6 one ends of rotatory swing arm by slip table feeding mechanism 4 earlier, is controlled rotatory swing arm 6 by first driving piece 7 and rotates 180 degrees after that for the material platform 8 of placing sealed pad cooperatees with thickness detection mechanism 5, carries out sealed pad thickness detection. At this moment, the material table 8 originally matched with the thickness detection mechanism 5 is changed into being matched with the sliding table material taking mechanism 4, and the sealing gasket to be detected is continuously transported to the upper side of the material table by the sliding table material taking mechanism 4.

After the sealing gasket on one of the material tables 8 is detected, the first driving piece 7 controls the rotating arm to rotate 180 degrees, so that the material tables 8 at two ends of the rotating swing arm 6 are replaced, and the sealing gasket which has finished the thickness detection can be taken out. The process is carried out repeatedly to improve the thickness detection efficiency of the sealing gasket.

Further, the thickness detection mechanism 5 comprises a measurement upright post 9, a fixed pressing plate 10 located above the material table 8 is arranged on one side of the measurement upright post 9, and a displacement sensor 11 capable of measuring the thickness of the sealing gasket is arranged on the fixed pressing plate 10. One side of the measuring column 9 is provided with a guide rail 12, the guide rail 12 is connected with a slide block 13 positioned below the material platform 8 in a sliding manner, and the rack 1 is further provided with a constant force driving assembly 14 capable of driving the slide block 13 to move towards the material platform 8.

If a sealing gasket is not arranged on the material table 8 matched with the thickness detection mechanism 5, the sliding block 13 jacks up the material table 8 under the action of the constant force driving component 14, so that the upper end face of the material table 8 is abutted to the lower end face of the fixed pressing plate 10;

if when placing sealed pad on the material platform 8 with thickness detection mechanism 5 matched with, under the effect of constant force drive assembly 14, slider 13 with material platform 8 jack-up upwards for sealed both ends are extruded by material platform 8 and fixed pressing plate 10 respectively, and the interval between the up end of material platform 8 and the lower terminal surface of fixed pressing plate 10 is A this moment, and this A is sealed pad thickness that displacement sensor 11 surveyed promptly.

Specifically, the following are mentioned: the thickness detection mechanism 5 extrudes the two end planes of the sealing gasket firstly, and then measures the thickness of the whole sealing gasket, and the measurement precision is high. In addition, thickness detection mechanism 5 still cooperatees with test revolving stage 3 and uses for every 180 degrees of rotation of test revolving stage 3 all can accomplish simultaneously and transport the sealed pad that awaits measuring to thickness detection mechanism 5, and will outwards take out through the sealed pad that thickness detected, with accomplish the process to thickness detection mechanism 5 pay-off (carry sealed pad) and ejection of compact (output sealed pad) in step. Thereby improving the speed of measuring the thickness of the gasket as a whole.

Further, the constant force driving assembly 14 includes a driving cylinder 15, a lever 16 and a bracket 17, an abdicating groove 18 capable of being matched with the lever 16 is formed on the upper end surface of the bracket 17, and the bracket 17 is rotatably connected with the middle part of the lever 16 in the abdicating groove 18 to form a fulcrum. One end of the lever 16 is rotatably connected to the output end of the driving cylinder 15, and the other end of the lever 16 is rotatably connected to a rolling bearing 19 which can abut against the lower end surface of the slider 13.

The distance between one end of the lever 16 close to the driving cylinder 15 and the fulcrum is larger than the distance between one end of the lever 16 close to the slider 13 and the fulcrum. When the driving cylinder 15 drives one end of the lever 16 to move downward, the end of the lever 16 having the rolling bearing 19 moves the slider 13 upward.

First, it is clear that: the distance between the end of the lever 16 close to the driving cylinder 15 and the fulcrum is a power arm, and the distance between the end of the lever 16 close to the slider 13 and the fulcrum is a resistance arm, so in the present application: the length of the power arm is greater than that of the resistance arm. Furthermore, according to the principle of the lever 16: power x power arm = resistance x resistance arm, and in the case where the resistance arm is smaller than the power arm, the resistance is inevitably greater than the power. Therefore, when the pushing force or pulling force generated by the driving cylinder 15 to one end of the lever 16 is used as power, the resistance applied to the slider 13 by the other end of the lever 16 through the rolling bearing 19 is inevitably greater than the output pushing force or pulling force of the driving cylinder 15, and the force amplification effect is achieved, so that the extrusion force of the material table 8 and the fixed pressing plate 10 to the two ends of the gasket is increased, and the two ends of the gasket are rapidly extruded, so that the efficiency and the accuracy of measuring the thickness of the gasket are improved.

Further, the driving cylinder 15 is a constant torque cylinder. The method and procedure for setting the constant torque of the cylinder are prior art and will not be described in detail herein. The driving cylinder 15 according to the present application can stably output a fixed pushing force or pulling force to act on one end of the lever 16 to provide a fixed power.

The output end of the driving cylinder 15 is parallel to the moving direction of the slide block 13 to form straight-up and straight-down transmission.

The output end of the driving cylinder 15 moves to drive the limiting rod 21 to move vertically and vertically, and acts on one end of the lever 16 through the limiting rod 21. In addition, because the lever 16 is rotatably connected with the bracket 17, when a force is applied to one end of the lever 16, the limiting rod 21 can move along the kidney-shaped groove 20 through the vertical up-and-down movement, so that the transmission process is safe and reliable.

Further, both ends of the rotary swing arm 6 are provided with circular grooves 22, the bottom of each circular groove 22 is provided with a square hole 23 in a penetrating manner, the cross-sectional area of each square hole 23 is smaller than that of each circular groove 22, and the bottom of each circular groove 22 forms a step.
