Description

Technical Field

[0001] This utility model relates to the field of sealing component testing technology, and in particular to a sealing component pressure resistance testing device. Background Technology

[0002] Seals are materials or parts used to prevent fluid or solid particles from leaking between adjacent mating surfaces and to prevent external impurities such as dust and moisture from entering the interior of machinery and equipment. Seals undergo surface inspection before leaving the factory to eliminate defective products.

[0003] In existing technologies, when testing seals, one side of the seal is first moved to the bottom of the testing device for testing, and then the seal is flipped over to test the other side. The existing testing devices are not ideal for quickly flipping the seals, so there is a need to provide a seal pressure resistance testing device to solve the above problems. Utility Model Content

[0004] The main purpose of this invention is to provide a pressure resistance testing device for sealing components, which can effectively solve the problems in the background art.

A drive motor is installed on one side of the support frame by bolts, and the drive motor is correspondingly arranged with the installation groove. The output end of the drive motor is connected to a bidirectional lead screw, and the two ends of the bidirectional lead screw are respectively installed on the inner walls of the two ends of the installation groove by bearings.

[0010] Preferably, a sliding block is sleeved on the outer wall of the bidirectional lead screw, and there are two sliding blocks, which are symmetrically distributed at both ends of the bidirectional lead screw. The sliding blocks are slidably connected inside the mounting groove, and an L-shaped support frame is installed on the top of the sliding blocks by bolts. The bottom two sides of the L-shaped support frame are slidably connected to the bottom inner wall of the support frame, and a support top plate is fixedly connected to the top of the L-shaped support frame.

[0011] Preferably, a hydraulic cylinder is bolted to the top center of the supporting top plate, and the bottom of the hydraulic cylinder penetrates through the supporting top plate. A sliding groove is provided in the middle of the side wall of the L-shaped support frame, and the bottom end of the hydraulic cylinder is connected to the inside of the sliding groove. A piston rod is installed on the movable end of the hydraulic cylinder, and a mounting frame is bolted to the bottom of the piston rod.

[0012] Preferably, the mounting frame is slidably connected inside the sliding groove, and the mounting frame has a groove on the side near the L-shaped support frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The clamping assembly is used to position and clamp the seal. The two sliding blocks drive the L-shaped support frame to move in opposite directions along the bidirectional screw, thereby causing the L-shaped support frame to drive the arc-shaped clamping plate to clamp the seal. This makes the device suitable for seals of different sizes.

[0016] 2. The rotating shaft and the arc-shaped clamping plate are driven to rotate by the rotating motor, which causes the arc-shaped clamping plate to flip the clamped seal. This facilitates the inspection of seals on different surfaces and improves the ease of use of the device. In addition, the hydraulic cylinder drives the mounting frame and the rotating motor to lower and raise, preventing the arc-shaped clamping plate from being too close to the bottom of the support frame, which would affect the flipping effect.

A sliding block 9 is disposed outside the bidirectional lead screw 8, an L-shaped support frame 10 is disposed on the top of the sliding block 9, and a support top plate 11 is disposed on the top of the L-shaped support frame 10. The mounting groove 6 is opened on the bottom inner wall of the support frame 2, and the mounting groove 6 is located in the middle of the bottom of the support frame 2. The drive motor 7 is bolted to one side of the support frame 2, and the drive motor 7 is correspondingly disposed to the mounting groove 6. The output end of the drive motor 7 is connected to the bidirectional lead screw 8, and the two ends of the bidirectional lead screw 8 are respectively mounted on the inner walls of the two ends of the mounting groove 6 through bearings. Sliding blocks 9 are fitted on the outer wall, and there are two sliding blocks 9, which are symmetrically distributed at both ends of the bidirectional screw 8. The sliding blocks 9 are slidably connected to the inside of the mounting groove 6, and an L-shaped support frame 10 is bolted to the top of the sliding blocks 9. The bottom two sides of the L-shaped support frame 10 are slidably connected to the bottom inner wall of the support frame 2. A support top plate 11 is fixedly connected to the top of the L-shaped support frame 10. The positioning and clamping of the seal is achieved by the clamping assembly 5. The two sliding blocks 9 drive the L-shaped support frame 10 to move in opposite directions along the bidirectional screw 8, so that the L-shaped support frame 10 drives the arc-shaped clamping plate 18 to clamp the seal, making the device suitable for seals of different sizes.

[0025] A hydraulic cylinder 12 is installed at the top of the supporting top plate 11, and a piston rod 19 is installed at the bottom of the hydraulic cylinder 12. A mounting frame 14 is installed at the bottom of the piston rod 19, and a rotary motor 16 is installed in the middle of the mounting frame 14. A rotating shaft 17 is installed on the side of the rotary motor 16, and an arc-shaped clamping plate 18 is installed at one end of the rotating shaft 17. The hydraulic cylinder 12 is bolted to the top center of the supporting top plate 11, and the bottom of the hydraulic cylinder 12 penetrates through the supporting top plate 11. A sliding groove 13 is opened in the middle of the side wall of the L-shaped support frame 10, and the bottom end of the hydraulic cylinder 12 is connected to the interior of the sliding groove 13. The piston rod 19 is installed at the movable end of the hydraulic cylinder 12, and the mounting frame 14 is bolted to the bottom of the piston rod 19. The mounting frame 14 is slidably connected to the interior of the sliding groove 13. A groove 15 is opened on the side of the mounting frame 14 near the L-shaped support frame 10, and the groove 15 has... Two, symmetrically distributed on both sides of the mounting frame 14, are arranged. The groove 15 contacts both sides of the L-shaped support frame 10.

[0026] It should be noted that this utility model is a pressure resistance testing device for a seal. During use, the drive motor 7 rotates the bidirectional lead screw 8, causing the two sliding blocks 9 to move the L-shaped support frame 10 in opposite directions along the bidirectional lead screw 8. This brings the arc-shaped clamping plate 18 into contact with the seal, allowing the two arc-shaped clamping plates 18 to position and clamp the seal, facilitating pressure resistance testing of the seal by the testing probe 4. When flipping is required, the hydraulic cylinder 12 drives the piston rod 19 and the mounting frame 14 to slide upwards within the sliding groove 13, causing the mounting frame 14 to drive the rotating motor 1... The 6 moves synchronously with the arc-shaped clamping plate 18, which drives the clamped seal to move, thereby adjusting the distance between the seal and the bottom of the support frame 2. At the same time, the rotary motor 16 drives the rotary shaft 17 to rotate, which drives the arc-shaped clamping plate 18 and the clamped seal to flip, making it easier to inspect different sides of the seal and improving the ease of use of the device. The grooves 15 on both sides of the mounting frame 14 are engaged in the middle of the L-shaped support frame 10, thereby limiting the connection between the mounting frame 14 and the rotary motor 16 and improving the stability of the device.
