Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe joint processing, in particular to an internal and external clamping device for processing large-size oil pipe joints. Background Art

[0002] The oil pipe joint is a detachable connecting part used to connect oil pipes and oil pipes, and oil pipes and hydraulic components in the hydraulic system. It should meet the requirements of firm connection, reliable sealing, small fluid resistance, compact structure, and easy disassembly and assembly. According to different connection methods and materials, oil pipe joints can be divided into many different types, such as straight-through, right-angle, tee, cross-way, hinged and other forms, as well as pipe end flaring, ferrule, welding, crimping and other connection methods. Oil pipe joints play a very important role in industrial equipment and are widely used in industrial fields such as petroleum, natural gas, and chemicals to ensure the safety and efficiency of fluid transmission.

[0003] After searching, a Chinese patent with publication number CN219401863U discloses a pipe joint processing and forming device. When the first protrusion and the second protrusion are matched, they are directly pushed by the cylinder alone, and lack a corresponding stable guide structure, so that the stability of the first protrusion and the second protrusion when matched will be seriously reduced, which can easily lead to a large error in the matching position, resulting in the block not being able to be quickly and stably inserted, seriously affecting the product processing efficiency. Therefore, when the pipe joint is formed, the main forming block and the auxiliary forming block can be stably matched, the matching stability is improved, and the product processing efficiency is effectively improved.

[0004] There are still some shortcomings in the above-mentioned oil pipe joint processing process. When installing the oil pipe before processing, the stability of the installation clamp is usually weak, which makes the joint easy to loosen during installation, which can easily cause the joint to shake during processing, resulting in reduced accuracy during joint processing and easy damage to the oil pipe joint during processing, thereby increasing processing costs and reducing processing efficiency.

An outer plate 12 is arranged on the opposite side of the inner plate 10, a spiral line 13 is arranged on the right side of the toothed disk 5, and two columnar grooves 14 are arranged on the opposite sides of the multiple inner plates 10. A spring 15 is fixedly connected inside the columnar groove 14, and the other end of the spring 15 is fixedly connected to a push shell 16. The handle 25 is rotated to drive the rotating rod 6 to drive the gear 7 to rotate, thereby facilitating the toothed disk 5 to rotate, and then the spiral line 13 is rotated to make the spiral line 13 move inside the multiple connecting plates 11, so as to facilitate pushing the multiple connecting plates 11 to approach each other for clamping, and while the connecting plates 11 are moving, they are limited by the limiting rod 9 when moving inside the hole groove 8.

[0033] As attached Figure 4As shown, the gear 7 and the toothed disk 5 are meshingly connected, the top of the mounting shell 17 is fixedly connected to a fixing box 19, the inner side of the top of the fixing box 19 is slidably connected to a mounting frame 20, the bottom end of the mounting frame 20 is fixedly connected to a clamping plate 21, the top of the clamping plate 21 is fixedly connected to two springs 22, the bottom end of the clamping plate 21 is fixedly connected to a threaded rod 23, the outer side of the threaded rod 23 is threadedly connected to a nut 24, and the other end of the rotating rod 6 is fixedly connected to a handle 25, so that the clamping plate 21 can be pushed to engage more tightly under the pushing action of the two springs 22, and then the threaded rod 23 is tightened by the nut 24 to improve the stability of the installation of the clamping plate 21.

[0034] As attached Figure 7 As shown, a mounting shell 17 is fixedly connected to the left side of the mounting disk 3, a mounting rod 18 is fixedly connected to the middle of the left side of the mounting disk 3, and the outer side of the pushing shell 16 is slidably connected to the inner side of the columnar groove 14.

[0035] As attached Figure 2 As shown, a plurality of threaded holes 26 are provided on the left side of the top of the joint mounting sleeve 4, and a bolt 27 penetrates the rear side of the handle 25 to fix the handle 25 after rotation and prevent the handle 25 from rotating.

[0036] Working principle: When in use, take out the two outer splints 12, and then place and assemble the two outer splints 12 on the oil pipe joint, and insert the oil pipe joint into the opposite sides of the multiple inner splints 10, and then rotate the handle 25, so that the handle 25 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the gear 7 to rotate, and the engagement between the gear 7 and the toothed disk 5 is conducive to the gear 7 driving the toothed disk 5 to rotate, and the toothed disk 5 drives the spiral line 13 to rotate.

Under the effect of double-layer clamping, it is beneficial to improve the stability of the oil pipe joint when clamping. When it is necessary to disassemble the clamping device, first screw the nut 24 to remove the nut 24 from the outside of the threaded rod 23, and then pull the mounting frame 20. The mounting frame 20 drives the card plate 21 to be pulled out, and the card plate 21 is pulled out to the inside of the fixed box 19, so that the card plate 21 is separated from the card plate 21, the mounting rod 18 and the inner side of the rotating sleeve 2 when it is pulled out, and then pull the mounting plate 3, so that the mounting plate 3 drives the mounting shell 17 and the mounting rod 18 to separate from the inside of the rotating sleeve 2, which is convenient for disassembling the clamping device. The operation during installation is reversed, which is beneficial to reduce the difficulty of operation during disassembly and assembly.
