Description

Technical Field

[0001] The utility model relates to the technical field of rubber ring detection, in particular to a tensile strength detection device for the production of rubber and plastic seals. Background Art

[0002] The rubber ring belongs to a kind of seal, which is fixed on a race or washer of a bearing and contacts or forms a narrow labyrinth gap with another race or washer to prevent the leakage of lubricating oil and the intrusion of foreign objects. Quality inspection is required during the production process of rubber rings.

[0003] During detection, generally, the sealing ring is first sleeved on the corresponding fixed column of the detection device, and then the sealing ring is pulled directionally to cause a certain deformation, and it is observed whether it breaks under a certain tensile force. After the detection is completed, the rubber ring is removed and the next one is detected. However, most of the existing fixed column structures are fixed. Therefore, when a sealing ring that does not fit the specification of the fixed column is sleeved on its surface, the sealing ring is likely to become loose during the stretching process, thus affecting the normal detection work. For this reason, we propose a tensile strength detection device for the production of rubber and plastic seals. Summary of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1:

[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution: a tensile strength detection device for the production of rubber and plastic seals, including a base 1, and further including a detection box 2 rotatably arranged on the base 1. A multi - segment detection head 3 is arranged on the detection box 2, and a drive assembly 4 is arranged in the detection box 2 to drive the multi - segment detection head 3 to move directionally to stretch the sealing ring.

[0027] A track 6 is fixedly arranged in the detection box 2, a connecting belt 7 is slidably arranged in the track 6, sliding grooves 8 are opened on both the upper and lower surfaces of the detection box 2, sliders 9 are arranged in the sliding grooves 8, and the sliders 9 are fixedly connected to the connecting belt 7. Through the connection of the connecting belt 7, one slider 9 can drive the other slider 9 to move, and the two sliders 9 are respectively located above and below the track 6, so that the moving directions of the two sliders 9 are opposite. Multi - segment detection heads 3 are fixedly arranged on one side of the top and bottom of the detection box 2, and multi - segment detection heads 3 are fixedly arranged on both sliders 9.

[0028] The driving component 4 includes a moving lead screw 41 rotatably arranged in the detection box 2. The moving lead screw 41 threadedly penetrates through the slider 9, and the end of the moving lead screw 41 rotatably penetrates through the detection box 2 and is fixedly connected to a driving motor 42 at the end. When the driving motor 42 starts, it drives the moving lead screw 41 to rotate. When the moving lead screw 41 rotates, it drives the slider 9 threadedly connected thereto to move.

[0029] The multi-section detection head 3 includes a fixed column 31. The fixed column 31 is arranged above the detection box 2. One fixed column 31 is fixedly arranged on the detection box 2, and the other fixed column 31 is fixedly arranged on the slider 9. A placement plate 32 is fixedly arranged on the outside of the fixed column 31. A plurality of collar rings 33 are arranged on the placement plate 32. The plurality of collar rings 33 are all slidably arranged on the outside of the fixed column 31, and adjacent collar rings 33 are slidably connected. A through groove is formed on the placement plate 32. A lifting member 5 capable of jacking up the collar ring 33 is arranged at the bottom of the collar ring 33. When the collar ring 33 is jacked up, the sealing ring to be tested can be installed on the outside of the collar ring 33. Therefore, the arrangement of the plurality of collar rings 33 can be applicable to sealing rings of different specifications.

[0030] The lifting member 5 includes an adjusting screw rod 51 rotatably penetrating through the fixed column 31. Moving blocks 52 are arranged on the outer sides of both ends of the adjusting screw rod 51. The moving blocks 52 are movably arranged in the through groove of the placement plate 32. The adjusting screw rod 51 threadedly penetrates through the moving blocks 52, and the thread directions at both ends of the adjusting screw rod 51 are opposite. A knob 53 is fixedly arranged at the end of the adjusting screw rod 51. A moving groove 54 is formed in the moving block 52. A top block 55 is slidably arranged in the moving groove 54. A connecting screw rod 56 is slidably arranged on the side wall of the moving block 52. A nut 57 is threadedly sleeved on the outside of the connecting screw rod 56. The end of the nut 57 abuts against the side wall of the moving block 52. When the knob 53 is rotated to drive the adjusting screw rod 51 to rotate, the adjusting screw rod 51 drives the moving blocks 52 to move towards each other. When it moves to a suitable position, that is, when the moving blocks 52 move below the collar ring 33 to be jacked up, at this time, the nut 57 is loosened so that the connecting screw rod 56 can drive the top block 55 to move upward, and the top block 55 jacks up the collar ring 33 above it. Then the nut 57 is rotated so that its end abuts against the moving block 52, thereby positioning the top block 55.

[0031] A transmission motor 10 is fixedly arranged on one side of the base 1. Rotating shafts 11 are arranged on both sides of the detection box 2. Any one of the rotating shafts 11 rotatably penetrates through one side of the base 1 and is fixedly connected to the transmission motor 10. By driving the detection box 2 to rotate through the transmission motor 10, the up-and-down alternating detection can be realized, improving the detection efficiency.

[0032] In summary, during the detection, first select a suitable collar 33 according to the specifications of the sealing ring, then install the sealing ring on the outer side of the collar 33, start the driving motor 42 to drive the slider 9 to move, so that the sealing ring is stretched. When the slider 9 moves, another slider 9 also moves under the action of the connecting belt 7, but the passive slider 9 moves in the direction of the fixed column 31, that is, closer to the fixed column 31. When it is stretched to a certain extent, if the sealing ring is not damaged, it is qualified. At this time, the transmission motor 10 is started to drive the detection box 2 to rotate 180 degrees, then the collar 33 originally at the bottom rotates to the upper side, and then install the next sealing ring to be detected on the collar 33. The driving motor 42 rotates in the reverse direction. At this time, the upper collars 33 move away from each other, and the lower collars 33 move closer to each other to drop the previously detected sealing ring. By analogy, the detection of the sealing ring can be carried out.

[0033] Embodiment 2:

[0034] Please refer to Figure 7 , the main structure of Embodiment 2 is the same as that of Embodiment 1. The difference is that an indicating rod 12 is fixedly arranged on one side of the moving block 52, and indicating grooves 13 are formed on the surfaces of the detection box 2 and the slider 9. Since the collar 33 is located at the top of the moving block 52, it is not easy to observe the position where the moving block 52 moves. Therefore, through the arrangement of the indicating rod 12 and the indicating grooves 13, the position where the moving block 52 needs to move can be conveniently observed, which is convenient for use.
