[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-4 This utility model provides an elasticity testing device for rubber production, including a workbench 2; a testing body 6 is installed on the top of the workbench 2; a connecting frame 7 is fixedly connected to the input end of the testing body 6; a fixing body 8 is fixedly connected to the top of the connecting frame 7; an internally threaded rod 11 is rotatably connected to the side of the fixing body 8; a rotating rod 13 is fixedly connected to the outer wall of the internally threaded rod 11; a clamping screw 12 is threadedly connected to the inner wall of the internally threaded rod 11; a sliding rod 9 is fixedly connected to one end of the clamping screw 12; the sliding rod 9 is slidably connected to the inner wall of the fixing body 8; and a fixing plate 10 is fixedly connected to one end of the sliding rod 9. During operation, when it is necessary to clamp the sample rubber, the internally threaded rod 11 and the rotating rod 13 can be rotated, so that the clamping screw 12 threadedly connected to the internally threaded rod 11 can drive the sliding rod 9 to slide inside the fixing body 8, so that the fixing plates 10 can move closer to each other, and the fixing plates 10 can stably clamp and fix the sample rubber, which facilitates subsequent rubber elasticity testing.

[0027] Furthermore, such as Figure 2 and Figure 4As shown, an auxiliary frame 3 is fixedly connected to the top of the workbench 2; a sliding block 5 is slidably connected to the outer wall of the auxiliary frame 3; a connecting frame 7 is fixedly connected to the bottom of the sliding block 5; a device base 1 is slidably connected to the outer wall of the workbench 2; a foot 21 is fixedly connected to the bottom of the device base 1; a limit block 14 is fixedly connected to the inner bottom wall of the device base 1; a limit rod 15 is slidably connected to the inner surface of the limit block 14; the limit rod 15 is fixedly connected to the bottom of the workbench 2; a sliding base 17 is fixedly connected to the inner bottom wall of the device base 1; a spring rod 18 is fixedly connected to the inner surface of the sliding base 17; a sliding auxiliary block 19 is slidably connected to the outer wall of the spring rod 18; a shock-absorbing spring 20 is fixedly connected between the sliding auxiliary blocks 19; a rotating support rod 16 is rotatably connected to the top of the sliding auxiliary block 19; the rotating support rod 16 is rotatably connected to the bottom of the workbench 2; a servo motor 22 is installed on the top of the auxiliary frame 3; an adjusting screw 4 is fixedly connected to the output end of the servo motor 22; the adjusting screw 4 is threadedly connected to the inner surface of the sliding block 5.

The rotating support rod 16 and the sliding auxiliary block 19 are rotatably connected, and the sliding auxiliary block 19 is limited by the spring rod 18. At the same time, the shock-absorbing spring 20 is set to buffer the sliding, thereby buffering the sliding of the device base 1 and the worktable 2 and reducing the impact of vibration on the detection device. After the sample rubber is clamped and fixed, the servo motor 22 can be started to rotate the adjusting screw 4, so that the sliding block 5 can be driven to move upward under the limit of the auxiliary frame 3, thereby stretching the rubber. The detection body 6 can detect the tensile force, thereby detecting the elastic force.

[0028] Working principle: When it is necessary to clamp the sample rubber, the internal thread rod 11 and the rotating rod 13 can be rotated, so that the clamping screw 12, which is threaded to the internal thread rod 11, can drive the sliding rod 9 to slide inside the fixed body 8. This allows the fixed plates 10 to move closer together, so that the fixed plates 10 can stably clamp and fix the sample rubber, which facilitates the subsequent rubber elasticity test. The device base 1 and the worktable 2 can slide relative to each other. At the same time, the rotating support rod 16 and the sliding auxiliary block 19 are rotatably connected, and the sliding auxiliary block 19 is limited by the spring rod 18. At the same time, the shock-absorbing spring 20 is set to buffer the sliding, thereby buffering the sliding of the device base 1 and the worktable 2 and reducing the impact of vibration on the detection device. After the sample rubber is clamped and fixed, the servo motor 22 can be started to rotate the adjusting screw 4, so that the sliding block 5 can be moved upward under the limit of the auxiliary frame 3, thereby stretching the rubber. At the same time, the detection body 6 can detect the tensile force, thereby detecting the elasticity.
