Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rubber O-ring performance testing, and particularly relates to a rubber O-ring performance testing device. Background Art
[0002] As a common sealing element, rubber O-rings are widely used in various mechanical equipment. However, due to the characteristics of rubber materials and the complexity of the use environment, problems such as leakage, wear, and aging may occur during the use of O-rings, thereby affecting the performance and reliability of the equipment.
[0003] In order to ensure the quality and performance of rubber O-rings, various performance tests need to be carried out on them. Among them, the tensile performance test is an important test method, which can evaluate key performance indicators such as the strength, elasticity, and durability of O-rings. However, when some existing experimental devices conduct tensile performance tests on O-rings, there are some limitations and they cannot achieve relatively precise tensile movements to ensure that the tensile rate and degree are uniform. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a rubber O-ring performance testing device. By setting a stretching component, the problem of not being able to achieve relatively precise tensile movements and ensuring that the tensile rate and degree are uniform is solved.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model is a rubber O-ring performance testing device, including a workbench, and a detection mechanism and an auxiliary mechanism are arranged on the workbench.
[0007] Further, the detection mechanism includes a stretching component and an extrusion component. The stretching component includes an L-shaped plate fixedly connected to the top of the workbench. The inner top wall of the L-shaped plate is fixedly connected with a frame. A motor is fixedly connected to the bottom of the workbench. The output end of the motor is fixedly connected with a bidirectional threaded rod. The top end of the bidirectional threaded rod extends into the interior of the frame and is rotationally connected with the frame. An internally threaded block one is threadedly connected to the frame. The front end of the internally threaded block one is fixedly connected with a placement plate one. An internally threaded block two is threadedly connected to the bidirectional threaded rod. The front end of the internally threaded block two is fixedly connected with a placement plate two.
[0008] Further, the extrusion mechanism includes a chute opened on the front side of the placement plate two. A clamping plate is slidably connected to the front side of the placement plate two. The rear side of the clamping plate is slidably connected to the inner wall of the chute.
[0009] Furthermore, a nut is fixedly connected to the top of the second placement plate. The inner wall of the nut is threadedly connected to a threaded rod. The bottom end of the threaded rod extends into the second placement plate and is rotationally connected to the second placement plate. The bottom end of the threaded rod contacts the top of the clamping plate. An O-ring is provided on the front sides of the first placement plate and the second internal threaded block.
[0010] Furthermore, the auxiliary mechanism includes a limiting component and a heating component. The limiting component includes a first sliding rod fixedly connected to the top of the workbench. A second sliding rod is fixedly connected to the top of the workbench. Two outer shells are slidably connected to the first sliding rod. Both of the two outer shells are slidably connected to the second sliding rod.
[0011] Furthermore, connecting blocks are fixedly connected to the inner walls of both of the two outer shells. Connecting rods are hinged to the sides of both of the two connecting blocks that are close to each other. The sides of the first internal threaded block and the second internal threaded block that are close to the outer shells are respectively hinged to the corresponding connecting rods.
[0012] Furthermore, the heating component includes a blower fixedly connected to the top of the workbench. An air suction pipe is fixedly connected to the input end of the blower. An air supply pipe is fixedly connected to the output end of the blower.
[0013] Furthermore, the left end of the air supply pipe is fixedly connected to a heating box. A plurality of heating wires are fixedly connected to the inside of the heating box. A corrugated pipe is fixedly connected to the left end of the heating box. The end of the corrugated pipe away from the heating box extends into the inner wall of the corresponding outer shell.
[0014] The utility model has the following beneficial effects:
[0015] 1. By providing a detection mechanism, when the motor is started, the motor drives the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, it drives the first internal threaded block and the second internal threaded block to move, thereby stretching the O-rings on the first internal threaded block and the second internal threaded block for a performance test. At the same time, the threaded rod is rotated. The threaded rod drives the clamping plate to slide in the chute by rotating on the inner wall of the nut, thereby fixing the O-ring by clamping with the clamping plate. Through the detection structure, a more accurate stretching action can be realized, ensuring that the stretching rate and degree are uniform. The bidirectional threaded rod can provide a stable and continuous stretching force, avoiding sudden force fluctuations. By pushing the clamping plate with the threaded rod to clamp and fix the O-ring, the anti-extrusion performance of the O-ring can also be tested.
[0016] 2. By providing a heating component, when the blower is started, air is conveyed into the heating box through the air suction pipe and the air supply pipe, and then the air in the heating box is heated by the heating wires. Finally, it is discharged through the corrugated pipe to conduct a high-temperature resistance test on the O-ring. Through the heating component, it is convenient to accurately set and maintain the required high-temperature conditions, ensuring the repeatability and reliability of the test. At the same time, using the heating box is relatively simple, and the equipment cost is relatively moderate.
[0017] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the clamping plate 29 is pushed by the threaded rod to clamp and fix the O-ring 212, and the anti-squeezing performance of the O-ring 212 can also be tested.
[0028] The auxiliary mechanism 3 includes a limiting component and a heating component. The limiting component includes a first slide bar 31 fixedly connected to the top of the workbench 1. A second slide bar 32 is fixedly connected to the top of the workbench 1. Two outer shells 33 are slidably connected to the first slide bar 31.

[0029] A specific application of this embodiment is as follows: Place the O-ring 212 in front of the first placement plate 26 and the second placement plate 28. Rotate the threaded rod 211, and the threaded rod 211 pushes the clamping plate 29 to slide on the inner wall of the chute 213, thereby clamping and fixing the O-ring 212. At the same time, the compression performance of the O-ring 212 can be tested according to the clamping condition of the clamping plate 29 on the O-ring 212. After the O-ring 212 is fixed, start the motor. The motor drives the bidirectional threaded rod 24 to rotate. When the bidirectional threaded rod 24 rotates, it drives the first internal thread block 25 and the second internal thread block 27 to move. When the first internal thread block 25 and the second internal thread block 27 move, they drive the first placement plate 26 and the second placement plate 28 to move, thereby conducting a tensile performance test on the O-ring 212. When the first internal thread block 25 and the second internal thread block 27 move, they drive the corresponding connecting rod 35 to move. When the connecting rod 35 moves, it drives the outer shell 33 to slide on the first slide rod 31 and the second slide rod 32 through the connecting block 34. The two outer shells 33 approach each other until they are completely fitted. Start the blower 36. The blower 36 inputs air into the heating box through the suction pipe 37 and the air supply pipe 38. The heating wire 310 inside the heating box 39 heats the air inside the heating box 39, and finally discharges it through the bellows 311. Since the two outer shells 33 approach each other and fit together, the hot air discharged from the bellows 311 can locally heat the inside of the two outer shells 33, creating a good high-temperature environment, and then conducting a high-temperature resistance test on the O-ring 212.
