Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipe fitting processing technology, specifically a fully automatic CNC machining device for hydraulic pipe fittings. Background Technology

[0002] Hydraulic steel pipes are a type of steel pipe specifically designed for hydraulic transmission systems, characterized by high precision, high strength, and high pressure resistance. They are typically made from high-quality carbon structural steel or alloy structural steel through multiple processing steps, such as cold drawing, cold rolling, and heat treatment. Precision hydraulic steel pipes are mainly used in the manufacture of hydraulic components such as hydraulic cylinders, hydraulic valves, and hydraulic pumps, as well as various high-pressure oil circuits and piping systems.

[0003] In the production of hydraulic pipe fittings, it is often necessary to weld and fix two sections of pipe fittings. In the existing technology, when welding hydraulic pipe fittings, the welding operation is mainly carried out manually by workers. Manual operation not only wastes manpower, but also the welding quality is closely related to the welding skills of the workers, making it difficult to control the welding quality and resulting in low welding efficiency.

[0004] Therefore, we propose a fully automatic CNC machining device for hydraulic pipe fittings. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0018] 1. This utility model, by setting up a pipe positioning mechanism and a welding mechanism, allows for the welding of hydraulic pipe fittings. Two sections of hydraulic pipe fitting are inserted into the two positioning sleeves of the U-shaped seat to connect them. The first fixing component then secures the hydraulic pipe fitting within the positioning sleeve. During welding, the first driving component can be activated to rotate the positioning sleeve, causing the positioning sleeve to rotate the hydraulic pipe fitting, thus performing comprehensive welding on the entire joint of the hydraulic pipe fitting. This reduces manual operation and improves welding efficiency.

Then, the second fixing component fixes the end of the hydraulic pipe that is away from the U-shaped seat into the support sleeve, which can support the tail of the hydraulic pipe, improve the stability of the hydraulic pipe, and thus improve the welding quality.

[0030] This utility model provides a technical solution:

[0031] Please see Figures 1-4 A fully automatic CNC machining device for hydraulic pipe fittings includes a worktable 1, a pipe fitting positioning mechanism 2, an auxiliary support mechanism 3, and a welding mechanism 4. The pipe fitting positioning mechanism 2 includes a U-shaped seat 21 fixedly connected to the middle of the worktable 1. Positioning sleeves 22 are rotatably installed on both sides of the U-shaped seat 21. The positioning sleeves 22 are provided with a first fixing member 23 for fixing the pipe fitting. The U-shaped seat 21 is provided with a first driving member 24 for driving the positioning sleeves 22 to rotate. By setting up the pipe fitting positioning mechanism 2, when welding hydraulic pipe fittings, two sections of hydraulic pipe fittings are respectively inserted into the two positioning sleeves 22 of the U-shaped seat 21 to connect the two sections of hydraulic pipe fittings. Then, the first fixing member 23 fixes the hydraulic pipe fittings in the positioning sleeves 22. During welding, the first driving member 24 can be activated to drive the positioning sleeves 22 to rotate, so that the positioning sleeves 22 drive the hydraulic pipe fittings to rotate, and the entire joint of the hydraulic pipe fittings is fully welded.

[0032] Specifically, the first fixing member 23 includes multiple first cylinders 231 fixedly installed on the positioning sleeve 22 and a first clamping plate 232 fixedly connected to the piston end of the first cylinder 231. By setting the first fixing member 23, when fixing the hydraulic pipe, the first cylinder 231 can be activated to drive the multiple first clamping plates 232 to move closer to each other, so that the first clamping plates 232 clamp the hydraulic pipe.

[0033] Specifically, the first driving component 24 includes a dual-axis motor 241 fixedly mounted on the U-shaped base 21. Gears 242 are fixedly connected to both output ends of the dual-axis motor 241. A gear ring 243 that meshes with the gears 242 is fixedly sleeved on the positioning sleeve 22. By setting the first driving component 24, the dual-axis motor 241 can be started to drive the two gears 242 to rotate, so that the two gears 242 respectively drive the gear rings 243 on the two positioning sleeves 22, and the positioning sleeves 22 are rotated through the gear rings 243.

[0034] Furthermore, the auxiliary support mechanism 3 includes auxiliary support seats 31 disposed on both sides of the U-shaped seat 21 and adjusting members 32 for adjusting the auxiliary support seats 31. A support sleeve 33 is rotatably mounted on the auxiliary support seat 31, and a second fixing member 34 for fixing the pipe fitting is disposed on the support sleeve 33. By setting the auxiliary support mechanism 3, when the two hydraulic pipe fittings are relatively long, the auxiliary support seat 31 can be adjusted to the end of the hydraulic pipe fitting away from the U-shaped seat 21 by adjusting members 32, so that the end of the hydraulic pipe fitting away from the U-shaped seat 21 extends into the support sleeve 33, and then the end of the hydraulic pipe fitting away from the U-shaped seat 21 is fixed in the support sleeve 33 by the second fixing member 34, which can support the tail of the hydraulic pipe fitting and improve the stability of the hydraulic pipe fitting.

[0035] Specifically, the adjusting component 32 includes a screw 321 rotatably mounted on the side wall of the U-shaped seat 21 and a servo motor 322 for driving the screw 321 to rotate. An auxiliary support seat 31 is sleeved on the screw 321 and threadedly connected to the screw 321. Guide rods 323 are fixedly connected to both sides of the U-shaped seat 21 located on the screw 321. The auxiliary support seat 31 is slidably sleeved on the guide rods 323. By setting the adjusting component 32, when dealing with hydraulic pipes of different lengths, the servo motor 322 can be started to drive the screw 321 to rotate, so that the screw 321 drives the auxiliary support seat 31 to slide along the guide rods 323, which facilitates the adjustment of the position of the auxiliary support seat 31.

[0036] Specifically, the second fixing member 34 includes multiple second cylinders 341 fixedly installed on the support sleeve 33 and a second clamping plate 342 fixedly connected to the piston end of the second cylinder 341. By setting the second fixing member 34, when fixing the hydraulic pipe, the second cylinder 341 can be activated to drive the multiple second clamping plates 342 to move closer to each other, so that the second clamping plates 342 clamp the hydraulic pipe.

[0037] Specifically, the welding mechanism 4 includes a welding head 41 set above the U-shaped seat 21, a bracket 42 fixedly installed on the worktable 1, a third cylinder 43 fixedly installed at the upper end of the bracket 42, and the welding head 41 installed on the piston end of the third cylinder 43. By setting the welding mechanism 4, during welding, the third cylinder 43 can be activated to drive the welding head 41 to descend, so that the welding head 41 can weld the joint of the two hydraulic pipes.

[0038] In practical use, the working principle of this utility model is as follows:

[0039] First, when welding hydraulic fittings, insert the two hydraulic fitting sections into the two positioning sleeves 22 of the U-shaped seat 21 respectively, so that the two hydraulic fitting sections are connected. Then, start the first cylinder 231 to drive multiple first clamping plates 232 to move closer to each other, so that the first clamping plates 232 clamp the hydraulic fittings. Then, fix the hydraulic fittings in the positioning sleeves 22 by the first fixing member 23.

[0040] When the two hydraulic pipe sections are relatively long, the servo motor 322 can be started to drive the screw 321 to rotate, so that the screw 321 drives the auxiliary support seat 31 to slide along the guide rod 323. The auxiliary support seat 31 is adjusted to the end of the hydraulic pipe that is away from the U-shaped seat 21, so that the end of the hydraulic pipe that is away from the U-shaped seat 21 extends into the support sleeve 33. Then, the second cylinder 341 is started to drive multiple second clamping plates 342 to move closer to each other, so that the second clamping plates 342 clamp the hydraulic pipe. The end of the hydraulic pipe that is away from the U-shaped seat 21 is fixed in the support sleeve 33 by the second fixing member 34, which can support the tail of the hydraulic pipe and improve the stability of the hydraulic pipe.

[0041] During welding, the third cylinder 43 can be activated to lower the welding head 41, allowing the welding head 41 to weld the joint of the two hydraulic pipe sections. At the same time, the first drive component 24 can be activated to rotate the positioning sleeve 22, causing the positioning sleeve 22 to rotate the hydraulic pipe, thus performing full welding on the entire joint of the hydraulic pipe.

[0042] In summary, this fully automatic CNC machining device for hydraulic pipe fittings, by setting up a pipe fitting positioning mechanism 2 and a welding mechanism 4, can automatically weld hydraulic pipe fittings, reduce manual operation, and improve welding efficiency.

[0043] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
