Description

Technical Field

[0001] This utility model relates to the field of sealing ring testing technology, and more specifically, to a sealing ring wear resistance testing device. Background Technology

[0002] Sealing rings are widely used components in hardware and plastics, water supply and drainage, HVAC, fire protection, pharmaceuticals, shipbuilding, pipeline systems, automobiles, motorcycles, various machinery, home appliances, electronics, toys, sports equipment, pneumatic components, and sanitary ware. In industrial production processes, it is often necessary to test the wear resistance of sealing rings.

[0003] In the prior art, a rubber sealing ring wear resistance testing device with application number 202022649226.8 discloses a motor threadedly connected to one end of the right side of the desktop surface. The motor is threadedly connected to a fixed plate via a connecting rod. A fixing device is connected through the connecting rod, and a fixed plate is snapped into the connecting rod. A friction block is threadedly installed on the desktop, located directly below the fixing device. A screw is spirally connected to the bottom end of the friction block. The above application sets multiple fixing devices on the connecting rod, and starting the motor can simultaneously perform wear resistance testing on multiple sealing rings, greatly improving efficiency. The fixing devices can be disassembled and replaced with different sizes, allowing multiple sealing rings of different sizes to be tested at once. However, when testing the sealing rings, the motor needs to be turned off, and then the fixing device needs to be installed on the connecting rod before the sealing rings can be tested. This affects the testing efficiency of the sealing rings, and it cannot be guaranteed that the friction coefficient between each friction block and the sealing ring is the same, affecting the testing quality of the sealing rings. Utility Model Content

[0004] In view of the problems in related technologies, this utility model proposes a sealing ring wear resistance testing device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows: A sealing ring wear resistance testing device includes a testing platform, a driving mechanism installed on the testing platform, the driving mechanism including a first motor, a connecting seat and a driving rod, a fixed seat connected to the driving mechanism, a connecting housing provided on the rear side of the testing platform, a second motor installed at one end of the connecting housing, a bidirectional lead screw connected to the output shaft of the second motor, the bidirectional lead screw being disposed inside the connecting housing, a moving block connected to the bidirectional lead screw, one end of the moving block passing through the connecting housing and connected to a connecting frame, a sliding plate fixedly connected to one end of the connecting frame, a friction block provided on one side of the sliding plate, and a limit block provided on the top of the sliding plate.

[0006] As a further optimization, the first motor is installed inside the testing platform, the output shaft of the first motor is connected to the connecting seat, and the drive rod is set on the connecting seat.

[0007] As a further optimization, the drive rod is arranged in a cross shape, and the fixing seat is provided with a socket that matches the drive rod, and the fixing seat is inserted into the drive rod.

[0008] As a further optimization, the fixing base is provided with arc-shaped grooves at equal intervals, and magnetic pieces are provided at both ends of the fixing base. The fixing base is magnetically attracted to the connecting base by the magnetic pieces.

[0009] As a further optimization, the bidirectional lead screw is symmetrically provided with left-hand threads and right-hand threads, and the moving block is symmetrically provided on the two sections of the threads of the bidirectional lead screw.

[0010] As a further optimization, the connecting housing is provided with a guide groove that matches the connecting frame, and the connecting frame passes through the guide groove and is fixedly connected to the moving block.

[0011] As a further optimization, the sliding plates are symmetrically arranged on both sides of the fixed base, and the friction blocks are arranged on the opposite side of the sliding plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By setting up a drive mechanism and a fixed seat, when testing the sealing ring, the sealing ring is installed into the arc-shaped groove of the fixed seat, and then the fixed seat is placed on the drive mechanism to test the sealing ring. The sealing ring can be placed on the fixed seat in advance when testing the sealing ring, so as to improve the testing efficiency of the sealing ring.

[0014] 2. By setting a sliding plate and a friction block, the fixed base is driven to rotate by the drive mechanism, which in turn drives the bidirectional lead screw to rotate. This causes the moving block to move in conjunction with the connecting frame, so that the friction block contacts the sealing ring on the fixed base and rubs it. This allows multiple sealing rings to be detected simultaneously, and ensures that the friction force between the friction block and each sealing ring is the same, thus improving the detection quality of the sealing rings.

[0023] like Figures 1 to 5As shown, a sealing ring wear resistance testing device includes a testing platform 1, a driving mechanism 2 mounted on the testing platform 1, the driving mechanism 2 including a first motor 3, a connecting seat 4, and a driving rod 5, a fixed seat 6 connected to the driving mechanism 2, a connecting housing 7 provided on the rear side of the testing platform 1, a second motor 8 mounted on one end of the connecting housing 7, a bidirectional lead screw 9 connected to the output shaft of the second motor 8, the bidirectional lead screw 9 being disposed inside the connecting housing 7, a moving block 10 connected to the bidirectional lead screw 9, one end of the moving block 10 passing through the connecting housing 7 and connected to a connecting frame 11, a sliding plate 12 fixedly connected to one end of the connecting frame 11, a friction block 13 provided on one side of the sliding plate 12, and a limit block 14 provided on the top of the sliding plate 12. The first motor 3... Installed inside the testing platform 1, the output shaft of the first motor 3 is connected to the connecting seat 4. The drive rod 5 is set on the connecting seat 4 and is arranged in a cross shape. The fixed seat 6 is provided with a matching insertion hole 15 for the drive rod 5. The fixed seat 6 is inserted into the drive rod 5. The fixed seat 6 is provided with arc-shaped grooves 16 at equal intervals. The two ends of the fixed seat 6 are provided with magnet pieces 17. The fixed seat 6 is magnetically attracted to the connecting seat 4 by the magnet pieces 17. The fixed seat 6 is placed on the drive rod 5 of the driving mechanism 2. The first motor 3 drives the connecting seat 4 to rotate, so that the drive rod 5 drives the fixed seat 6 to rotate. By providing magnet pieces 17 on the fixed seat 6, it can be attracted to the connecting seat 4, which improves the tightness of the connection between the fixed seat 6 and the driving mechanism 2.

[0024] Preferably, the bidirectional lead screw 9 is symmetrically provided with left-hand threads and right-hand threads, and the moving block 10 is symmetrically provided on the two sections of the threads of the bidirectional lead screw 9. The connecting housing 7 is provided with a guide groove 18 that matches the connecting frame 11. The connecting frame 11 passes through the guide groove 18 and is fixedly connected to the moving block 10. The second motor 8 drives the bidirectional lead screw 9 to rotate, so that the moving block 10 cooperates with the connecting frame 11 to drive the sliding plate 12 to move, so that the friction block 13 fits against the outer wall of the sealing ring, and the wear resistance of the sealing ring is tested.

[0025] Furthermore, the sliding plates 12 are symmetrically arranged on both sides of the fixed base 6, and the friction blocks 13 are arranged on the opposite side of the sliding plates 12. This allows for the simultaneous detection of multiple sealing rings, and ensures that the friction force between the friction blocks 13 and each sealing ring is the same, thereby improving the detection quality of the sealing rings.

[0026] In summary, when using this device, the sealing ring is installed into the arc-shaped groove 16 of the fixed seat 6, and then the fixed seat 6 is placed on the drive rod 5 of the drive mechanism 2. The first motor 3 drives the connecting seat 4 to rotate, which in turn drives the fixed seat 6 to rotate. The second motor 8 drives the bidirectional lead screw 9 to rotate, which in turn drives the moving block 10 to move the sliding plate 12 in conjunction with the connecting frame 11. This allows the friction block 13 to fit against the outer wall of the sealing ring, thus performing wear resistance testing on the sealing ring. This device can test multiple sealing rings simultaneously and ensures that the friction force between the friction block 13 and each sealing ring is the same, improving the quality of sealing ring testing. Furthermore, the sealing ring to be tested can be installed on another fixed seat 6 in advance. After testing the sealing ring on one fixed seat 6, the sealing ring on the other fixed seat 6 can be tested immediately, thus improving the efficiency of sealing ring testing.
