Description

Technical Field

[0001] This application relates to the field of oil pipe joint technology, specifically an oil pipe joint fixing device. Background Technology

[0002] A tubing fitting is a component used to connect oil pipes. It plays a crucial role in hydraulic systems and oil transmission. The main function of the tubing fitting is to ensure a secure connection and reliable seal between oil pipes, preventing oil leakage and ensuring the normal operation of the oil circuit. The tubing fitting is fixed using a three-jaw chuck, allowing for stable machining. The three-jaw chuck rotates a small bevel gear (usually driven by a wrench), which in turn drives a large bevel gear. The flat thread on the back of the large bevel gear engages with the three jaws, achieving synchronous radial movement of the jaws.

[0003] However, when using existing three-jaw chucks to fix tubing joints, the arc-shaped structure on the inner side of the three-jaw chuck makes it easy to not clamp the tubing joint tightly enough. At the same time, the three-jaw chuck as a whole is not stable enough during installation, causing the entire chuck to have a tapered deviation and uneven clamping force, which affects the fixation of the tubing joint by the three-jaw chuck.

[0004] Therefore, there is an urgent need for a pipe fitting fixing device to solve the problem of insufficient stability in fixing pipe fittings by a three-jaw chuck. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a pipe fitting fixing device that improves the stability of the three-jaw chuck in clamping the pipe fitting, thus solving the problem of insufficient stability in fixing the pipe fitting by the three-jaw chuck.

[0006] To achieve the above objectives, this application provides the following technical solution: an oil pipe joint fixing device, comprising a chuck body and a clamping block, wherein the clamping block is installed on the top of the chuck body, and a fixing mechanism is provided on the outside of the chuck body, the fixing mechanism comprising a fixing block, a support sleeve, a support tube and a bolt body, wherein the fixing block is disposed on the outside of the chuck body, the support sleeve is rotatably connected to a groove on the inside of the fixing block, the support tube is slidably connected to the inside of a groove at the bottom of the fixing block, and the bolt body passes through the support sleeve and the support tube, wherein the support tube is threadedly connected to the support sleeve.

[0007] By adjusting the height of the support tube, the support tube provides overall support to the three-jaw chuck, keeping the three-jaw chuck horizontal. This prevents the three-jaw chuck from tilting or exhibiting uneven clamping force when clamping the tubing joint, thus improving the stability of the three-jaw chuck in fixing the tubing joint.

[0008] Preferably, four sets of limiting blocks are provided on the outer side of the fixing block, and the outer side of the limiting blocks is slidably connected to the inner side of the bottom groove of the fixing block.

[0009] Preferably, limiting plates are welded to both ends of the limiting block, and the limiting plates are welded to the outer surface of the fixing block.

[0010] Preferably, the fixing block is a U-shaped plate.

[0011] Preferably, the support sleeve is connected to the fixed block via a bearing.

[0012] Preferably, a gasket is bonded to the groove on the inner side of the clamping block, and several groups of the gaskets are evenly distributed on the inner side of the clamping block, and the inner side of the clamping block is an arc-shaped plate.

[0013] In summary, this application includes at least one of the following beneficial effects:

[0014] 1. When the chuck body is installed, the operator can rotate the support sleeve of this oil pipe joint fixing device. The support sleeve drives the support pipe to move up and down, keeping the three-jaw chuck horizontal. This makes it less likely for the three-jaw chuck to skew or have uneven clamping force when clamping the oil pipe joint, thus improving the stability of the three-jaw chuck in fixing the oil pipe joint.

[0015] 2. The tubing joint fixing device has an arc-shaped plate on the inner side of the clamping block, which can clamp the tubing joint more tightly and improve the stability of the three-jaw chuck. At the same time, the gasket can increase the friction between the three-jaw chuck and the tubing joint, making the three-jaw chuck clamp the tubing joint more stably and less prone to slippage.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1-4 A pipe fitting fixing device includes a chuck body 1 and a clamping block 2. The clamping block 2 is installed on the top of the chuck body 1 and can slide on the top of the chuck body 1. When the clamping block 2 moves inward, it can clamp the pipe fitting. A fixing mechanism is provided on the outside of the chuck body 1. The fixing mechanism includes a fixing block 3, a support sleeve 4, a support tube 5, and a bolt body 7. The fixing block 3 is located on the outside of the chuck body 1. The support sleeve 4 is rotatably connected to the groove on the inside of the fixing block 3. The support sleeve 4 is connected to the fixing block 3 through a bearing. The support tube 5 is slidably connected to the inside of the bottom groove of the fixing block 3. The fixing block 3 is a U-shaped plate. The bolt body 7 passes through the support sleeve 4 and the support tube 5. The support tube 5 is threadedly connected to the support sleeve 4. Four sets of limiting blocks 6 are provided on the outside of the fixing block 3. The outside of the limiting blocks 6 is slidably connected to the inside of the bottom groove of the fixing block 3. Limiting plates 8 are welded to both ends of the limiting blocks 6 and are welded to the outer surface of the fixing block 3.

[0023] With the above technical solution, when the chuck body 1 is installed, after the chuck body 1 is placed in the preset position, the operator inserts the bolt body 7 into the support sleeve 4 and the support tube 5 to connect to the preset position. At the same time, the operator can rotate the support sleeve 4, which drives the support tube 5 to move up and down, thereby changing the support height of the bottom of the fixing block 3, thus making overall fine adjustments to the three-jaw chuck. When the support tube 5 moves, it drives the limiting block 6 to slide inside the fixing block 3. The limiting piece 8 limits the distance the support tube 5 moves. Through the support tube 5 supporting the three-jaw chuck as a whole, the three-jaw chuck is kept horizontal, so that when the three-jaw chuck clamps the oil pipe joint, it is not easy to have problems with skewing and uneven clamping force, thus improving the stability of the three-jaw chuck in fixing the oil pipe joint.

[0024] Specifically, a gasket 9 is bonded to the groove on the inner side of the clamping block 2. Several sets of gaskets 9 are evenly distributed on the inner side of the clamping block 2, and the inner side of the clamping block 2 is an arc-shaped plate.

[0025] Through the above technical solution, the inner side of the clamping block 2 is an arc-shaped plate, which increases the contact area between the clamping block 2 and the oil pipe joint, and can clamp the oil pipe joint more tightly, improving the stability of the three-jaw chuck clamping. At the same time, the gasket 9 can increase the friction between the three-jaw chuck and the oil pipe joint, making the three-jaw chuck clamp the oil pipe joint more stably and less prone to slippage.

[0026] During use, by adjusting the height of the support tube 5, the support tube 5 supports the entire three-jaw chuck, keeping the entire three-jaw chuck horizontal. This prevents the three-jaw chuck from tilting or unevenly clamping when clamping the oil pipe joint, thus improving the stability of the three-jaw chuck in fixing the oil pipe joint.
