Description

Technical Field

[0001] The utility model relates to the technical field of rubber ring tension detection equipment, in particular to a rubber ring tension detection machine. Background Art

[0002] The rubber ring is an annular cover composed of one or more parts, which is fixed on a ring or washer of the bearing and contacts with the other ring or washer or forms a narrow labyrinth gap to prevent lubricating oil leakage and foreign objects from intruding.

[0003] Before rubber rings are put on the market, it is generally necessary to sample a batch of rubber rings and test the tension of the rubber rings using a tensile testing machine. This can be a threshold test of the tension or an ultimate tensile value test. When testing rubber rings with traditional tensile testing machines, if the rubber ring breaks, the rubber ring will bounce off and leave the tensile testing machine, making it difficult to recover. In addition, the lifting and pulling parts of most tensile testing machines are only lifted and pulled by cylinders, which have poor stability and positioning. Therefore, an improved technology is urgently needed to solve this problem existing in the existing technology. Utility Model Content

[0024] The lifting mechanism includes a cylinder 7, a connecting rod 8 and a guide rod 9. The cylinder 7 is arranged in the middle position of the upper surface of the top plate 3. The piston rod of the cylinder 7 passes through the top plate 3 and is connected to the top of the connecting rod 8 through a coupling 10. A socket is provided at the bottom of the connecting rod 8. The top of the movable pull head 12 is inserted into the socket at the bottom of the connecting rod 8 and is fastened by bolts. Guide rods 9 are provided on both sides of the connecting rod 8. The guide rod 9 is away from one end of the connecting rod 8 and slides with the guide groove 6 of the side baffle 4 on the corresponding side. A limit block 16 is provided at the outer end of the guide rod 9 by a bolt. The limit block 16 slides with the outer surface of the side baffle 4 on the corresponding side. The limit block 16 ensures that the guide rod 9 will not shake left and right, thereby further ensuring the stability of the connecting rod 9;

[0025] The tension sensor 11 is arranged in the middle position of the upper surface of the machine 1 through the mounting base 14. A connecting sleeve 15 is provided on the upper surface of the tension sensor 11. The fixed pull head 13 is plugged into the connecting sleeve 15 and fastened by bolts. The fixed pull head 13 and the movable pull head 12 correspond to each other and cooperate with each other.

[0026] like Figure 4 As shown, the movable slider 12 and the fixed slider 13 have the same structure and are both composed of a rod body 18 and a semicircular slider 19. A semicircular slider 19 is provided on the side of one end of the rod body 18, and a groove 20 is provided on the semicircular slider 19 near one end of the rod body 18. The movable slider 12 and the fixed slider 13 of the structure facilitate the positioning of the rubber ring, and are also convenient for connection and disassembly with the bottom of the connecting rod 8 and the connecting sleeve 15.

[0027] Installation method and operating principle: First, install the support columns 2 at the four corners of the upper surface of the machine 1. Then, bolt the bottom ends of the side panels 4 and rear panel 5 to the upper surface of the machine 1. Then, slide the guide rods 9 on both sides of the connecting rod 8 from the top of the side panels 4 into the guide grooves 6. Then, bolt the top panel 3 to the tops of the support columns 2, side panels 4, and rear panel 5. Install the cylinder 7 on the upper surface of the top panel 3 and pass its piston rod through the top panel 3. Then, connect it to the top of the connecting rod 8 via the coupling 10. Next, connect the tension sensor 11 with the connecting sleeve 15 welded to the top to the upper surface of the machine 1 through the mounting base 14. At this point, the connecting rod 8 and the connecting sleeve 15 are on the same axis, completing the installation. When in use, select the appropriate movable slider 12 and fixed slider 13 according to the rubber ring to be tested, insert the rod body 18 of the movable slider 12 into the jack at the bottom of the connecting rod 8 and tighten it with bolts, insert the rod body 18 of the fixed slider 13 into the connecting sleeve 15 and tighten it with bolts, and push the piston rod of the cylinder 7 outward to drive the movable slider 12 to move down and close to the fixed slider 13 through the connecting rod 8, so that the rubber ring is put on the fixed slider 13 and the movable slider 12, and the piston rod of the cylinder 7 is recovered. The tension of the rubber ring is detected by the tension sensor 11, so as to detect whether the tension of the rubber ring meets the requirements, or detect the limit tension of the rubber ring. When the rubber ring does not meet the requirements or reaches the limit tension and is disconnected, the rubber ring can be blocked by the side baffle 4 or the rear baffle 5 (the rubber ring generally bounces in the radial direction after being disconnected). The utility model has a reasonable structure. Side baffles 4 are provided on the upper surface of the machine 1 and on both sides of the movable slider 12 and the fixed slider 13. A rear baffle 5 is also provided between the two side baffles 4. When the rubber ring tension test is performed, after the rubber ring is broken and bounced off, the broken rubber ring can be prevented from bouncing to the outside through the blocking of the side baffles 4 and the rear baffle 5, which facilitates the collection of the rubber ring. In addition, the side baffles 4 are provided with guide grooves 6, and guide rods 9 are provided on both sides of the connecting rod 8. The cooperation of the guide rods 9 and the guide grooves 6 of the side baffles 4 greatly improves the stability and positioning of the connecting rod 8, ensuring that the movable slider 12 and the fixed slider 13 are located on the same axis, thereby ensuring the detection accuracy.
