Technical Field

[0001] This utility model relates to the field of flange technology, specifically to a tooling for testing pipe connection flanges. Background Technology

[0002] A flange connection is a detachable joint where two pipes, fittings, or equipment are first fixed to a flange, then a flange gasket is placed between the two flanges, and finally bolts are used to tighten the two flanges together. It allows for connections between stationary pipes and rotating or reciprocating equipment.

[0003] The prior art document, "A Pipeline Connection Flange Inspection Fixture," (CN222843902U), describes a fixture that uses a base, a two-way threaded rod, a threaded sleeve, a moving block, a moving plate, a fixed rod, a fixed plate, a rotating shaft, locking screws, and a clamping plate to work together. During use, the two moving plates move towards the center, which in turn moves the clamping plate towards the center, thus clamping and limiting the flange. This allows the user to easily clamp and limit the flange for inspection.

[0004] However, the flange inspection fixture is inconvenient to use, as it cannot quickly clamp and lock flanges of any size, causing inconvenience to users and no longer meeting their needs. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe connection flange inspection fixture to solve the problem mentioned in the background art that the flange inspection fixture is inconvenient to use, cannot quickly clamp and lock flanges of any size, causing inconvenience to users, and can no longer meet the needs of users.

A display screen is fixedly mounted on the front surface of the clamping block. Support frames are fixedly mounted on opposite sides of the two pressure sensors. Movable rods are fixedly mounted on opposite sides of the two support frames. The opposite sides of the two movable rods pass through the clamping block and extend into its interior. The opposite sides of the two movable rods pass through the support frames and extend into their interiors. A guide block is fixedly mounted on one side of the bottom of the clamping block. A guide groove is formed near the middle of the movable rod. The front end of the guide block extends into the guide groove and slides between it and the guide groove. Return springs are fixedly mounted on opposite sides of the two guide blocks. The opposite sides of the two return springs are fixedly connected to the inner wall of the guide groove.

[0007] Furthermore, the hand grip adopts a cylindrical design.

[0008] Furthermore, the front end of the clamping block extends to the outside of the cross groove, and the clamping block is slidably connected to the cross groove.

[0009] Furthermore, the opposing sides of the two lead screws both penetrate the clamping block and extend to its exterior, and the opposing sides of the two lead screws are movably connected to the inner wall of the cross groove via a rotating shaft.

[0010] Furthermore, the bevel gear meshes with the bevel gear disk.

[0011] Furthermore, the rotating block and the hand grip are in contact with each other.

[0021] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not intended to limit the scope of protection of this utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution: a pipe connection flange inspection fixture, including a cross rod 1, a cross groove 2 for user installation, a cross groove 2 on the front surface of the cross rod 1 for mounting corresponding components, a clamping block 3 inside the cross groove 2 for clamping the flange, a lead screw 4 inside the cross groove 2 for moving the clamping block 3, a hand grip 5 fixedly mounted on the rear surface of the cross rod 1 for user gripping, and bevel gears 6 fixedly mounted on opposite sides of the two lead screws 4. Gear 6 drives lead screw 4 to move. A cavity is provided inside the handgrip 5. A rotating block 7 is located at the bottom of the handgrip 5, which drives connecting rod 9 to rotate. A bevel gear 8 is located near the center of the cross groove 2, which drives bevel gear 6 to rotate. A connecting rod 9 is fixedly installed at the front end of the rotating block 7, connecting to the bevel gear 8. A pressure sensor 10 is fixedly installed in the center of the clamping block 3, which senses the clamping force to prevent over-clamping. A display screen 11 is fixedly installed on the front surface of the clamping block 3. 11 is electrically connected to the pressure sensor 10 via a power cord, enabling real-time display of the monitored values. Support frames 12 are fixedly mounted on opposite sides of each pressure sensor 10. The support frames 12 house movable rods 13. The movable rods 13 are used to transmit force through workpiece contact. Under the abutment of the workpiece, they press against the pressure sensor 10 to transmit pressure. The opposite sides of each movable rod 13 penetrate the clamping block 3 and extend into it. The opposing sides of each movable rod 13 penetrate the support frame 12 and extend... Inside the clamping block 3, a guide block 14 is fixedly installed on one side of the bottom. The guide block 14 works in conjunction with the guide groove 15. The movable rod 13 has a guide groove 15 in the middle. The guide groove 15 works in conjunction with the guide block 14 to guide the movable rod 13. The front end of the guide block 14 extends into the interior of the guide groove 15 and slides between them. A return spring 16 is fixedly installed on the opposite side of each of the two guide blocks 14. The return spring 16 can drive the movable rod 13 to move. The opposite side of each of the two return springs 16 is fixedly connected to the inner wall of the guide groove 15.

[0023] Furthermore, the handgrip 5 adopts a cylindrical design, which makes it easier for the user to grip.

[0024] Furthermore, the front end of the clamping block 3 extends to the outside of the cross groove 2, and the clamping block 3 and the cross groove 2 are slidably connected, wherein the clamping block 3 is capable of clamping the flange.

[0025] Furthermore, the opposing sides of the two lead screws 4 both penetrate the clamping block 3 and extend to its outside. The opposing sides of the two lead screws 4 are movably connected to the inner wall of the cross groove 2 through a rotating shaft. The lead screws 4 can drive the clamping block 3 to move.

[0026] Furthermore, the bevel gear 6 meshes with the bevel gear disc 8, and this design enables power transmission.

[0027] Furthermore, the rotating block 7 is in contact with the hand grip 5, wherein the rotating block 7 can drive the connecting rod 9 to rotate.

[0028] Furthermore, the front end of the connecting rod 9 passes through the hand grip 5 and the cross bar 1 in sequence and is fixedly connected to the bevel gear disk 8. The connecting rod 9 can drive the bevel gear disk 8 to rotate.

[0029] Working principle: When using this device to clamp a flange, the user places the flange at the center of the cross bar 1. Then, the user rotates the rotating block 7 to drive the connecting rod 9 to rotate. The rotation of the connecting rod 9 drives the bevel gear 8 to rotate. The rotation of the bevel gear 8 drives the bevel gear 6 to rotate. The rotation of the bevel gear 6 drives the lead screw 4 to rotate. The rotation of the lead screw 4 drives the clamping block 3 to move, thereby clamping the flange.

[0030] Based on the above work process, we can conclude that:

[0031] This pipe connection flange inspection fixture, with its screw 4, rotating block 7, bevel gear 6, and bevel gear disc 8, enables the device to quickly clamp the flange during use, thereby saving the user's time, improving the efficiency of flange inspection, bringing convenience to the user, enhancing the practicality of the device, and meeting the user's needs.
