Description

Technical Field

It is elastic at room temperature, can undergo large deformations under small external forces, and can return to its original shape after the external force is removed. Rubber products are widely used in various aspects of industry and daily life.

[0003] After the rubber product is manufactured, it needs to undergo an elasticity test. The rubber elasticity test can detect the number of times the rubber is repeatedly stretched, thereby determining whether the rubber is qualified. Existing technology, such as the patent publication number CN223295610U, discloses a rubber elasticity testing device, including a base. Positioning rods are fixedly connected to both sides of the top of the base. A top plate is fixedly connected to the top of the positioning rods. A reciprocating motion mechanism is provided at the bottom of the top plate. A test plate is provided at the bottom of the reciprocating motion mechanism. The test plate has positioning holes for the positioning rods to pass through. The positioning rods pass through the positioning holes. A plurality of first clamps are provided at the bottom of the test plate. A second clamp corresponding to the plurality of first clamps is provided at the top of the base.

[0004] The drawback of existing patented technologies is that the rubber elasticity test involves a fixed stretching range, which makes it impossible to perform repeated stretching tests according to the required stretching range of different rubber materials. Utility Model Content

[0024] Example 1

[0025] Reference Figures 1-4 This utility model discloses a rubber elasticity testing device with adjustable tensile amplitude, including a fixed clamp 1 and a movable clamp 2 arranged opposite each other, and a frame 3. An adjustable stroke reciprocating motion mechanism is installed in the frame 3. The adjustable stroke reciprocating motion mechanism includes a rotating disk 4, a swing column 5 and a reciprocating rod 6. The swing column 5 is detachably connected along the diameter direction of the rotating disk 4. One end of the reciprocating rod 6 is fixedly installed with the movable clamp 2. A fixed clamp 1 corresponding to the movable clamp 2 is fixed on the side wall of the frame 3.

[0026] With the above structure, since one end of the rubber is fixed on the fixed clamp 1 and the other end is fixed on the movable clamp 2, the rotating disk 4 is controlled to rotate, and then the reciprocating rod 6 is driven to reciprocate through the swing column 5 structure, thereby driving the rubber to perform repeated tensile tests. By adjusting one end of the swing column 5 to different positions along the diameter direction of the rotating disk 4, the stroke of the reciprocating clamp 2 on the reciprocating rod 6 can be adjusted to adjust the repeated tensile amplitude of the rubber, which can adapt to the tensile test requirements of different rubber materials.

[0027] In detail, in this embodiment, the adjustable stroke reciprocating motion mechanism includes a support plate 7 and a reciprocating plate 10. A guide plate 8 is fixed to the side wall of the support plate 7, and a bearing seat 9 is fixedly installed on the guide plate 8. A reciprocating rod 6 is inserted into the bearing seat 9. A movable through groove 11 is opened inside the reciprocating plate 10. A swing column 5 is eccentrically arranged on the side wall of the rotating disk 4. The swing column 5 is slidably connected to the inside of the movable through groove 11. The end of the reciprocating rod 6 away from the movable clamp 2 is fixed to the side wall of the reciprocating plate 10. When the rotating disk 4 rotates, it will drive the swing column 5 to rotate. The reciprocating rod 6 is restricted by the bearing seats 9 on both sides, and the swing column 5 will slide inside the movable through groove 11 of the reciprocating plate 10 to drive the movable clamp 2 installed on the reciprocating rods 6 on both sides to reciprocate.

[0028] In order to adjust the position of the swing column 5 so as to adjust the repeated stretching amplitude of the rubber, in this embodiment, a fixed slide rail is fixed along the diameter of the rotating disk 4 to the side wall of the rotating disk 4. A movable slider 12 is slidably connected in the fixed slide rail. The swing column 5 is fixed to the top of the movable slider 12. The bottom of the movable slider 12 is provided with a locking member connected to the rotating disk 4.

[0029] Specifically, the fixed slide rail includes two rail bodies 18, with mounting plates 19 welded to the ends of the rail bodies 18. The mounting plates 19 are fixed to the rotating disk 4 by screws. The rail bodies 18 have stepped slide grooves 20 inside, and the movable slider 12 is slidably connected between the stepped slide grooves 20 of the two rail bodies 18.

[0030] By unlocking the locking mechanism, the swing column 5 moves within the stepped slide groove 20 via the sliding slider 12 to adjust the center distance between the swing column 5 and the rotating disk 4. After adjustment, the locking mechanism is locked to fix the position of the swing column 5. This causes the amplitude of the swing column 5's reciprocating motion to change as the rotating disk 4 rotates, thereby changing the distance between the movable clamp 2 and the fixed clamp 1, thus meeting the tensile test requirements for different tensile amplitudes.

[0031] In detail, in this embodiment, a drive shaft 16 is rotatably connected inside the support plate 7, and a working motor 17 is fixed to the side wall of the support plate 7. The output end of the working motor 17 is connected to one end of the drive shaft 16, and a rotating disk 4 is fixed to the other end of the drive shaft 16. Driven by the working motor 17, the rotating disk 4 can be rotated by the drive shaft 16. The swing column 5 and the reciprocating plate 10 drive the reciprocating rod 6, which is equipped with the movable clamp 2, to reciprocate, so as to perform a tensile test on the rubber connected between the fixed clamp 1 and the movable clamp 2.

[0032] The fixed clamp 1 and the movable clamp 2 can be clamps, chucks or other clamping components.

[0033] Example 2

[0034] Reference Figures 1-4Based on the same concept as in Embodiment 1, the locking component of this adjustable tensile strength rubber elasticity testing device includes a locking stud 13 and a nut 14. A mounting slot 15 located on the diameter of the rotating disk 4 is formed on its surface. The top end of the locking stud 13 is fixed to the bottom of the movable slider 12, and the locking stud 13 passes through the bottom end of the mounting slot 15 and is locked by the nut 14. By controlling the movement of the locking stud 13 within the mounting slot 15, the center distance between the swing column 5 and the rotating disk 4 can be adjusted. After adjustment, the position of the locking stud 13 can be fixed by the nut 14. It should be noted that when adjusting the locking stud 13 using the nut 14, the rotating disk 4 can be rotated so that the position of the nut 14 is not obstructed by the support plate 7 or the guide plate 8.

[0035] Working principle:

[0036] The swing column 5 is adjusted according to the repeated stretching amplitude of the rubber to be tested. By unlocking the nut 14, the locking stud 13 is controlled to move in the mounting slot 15 so as to adjust the center distance between the swing column 5 and the rotating disk 4. After the adjustment is completed, the position of the locking stud 13 can be fixed by the nut 14.

[0037] After fixing, start the working motor 17. The working motor 17 drives the rotating disk 4 to rotate through the drive shaft 16. The rotating disk 4 is driven to move back and forth through the swing column 5 and the reciprocating plate 10. This is to perform a tensile test on the rubber connected between the fixed clamp 1 and the movable clamp 2, thereby meeting the requirements for repeated tensile tests with different tensile amplitudes.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
