Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device for preventing deformation of thin-walled hydraulic pipe components. Background Technology

[0002] In the field of hydraulic system manufacturing, hydraulic hoses, as key components for transmitting hydraulic energy, directly determine the operational stability and safety of the entire hydraulic system. Among them, thin-walled hydraulic hoses are widely used in many industries such as engineering machinery, aerospace, and automobile manufacturing due to their advantages such as light weight, high material utilization, and strong installation flexibility.

[0003] Currently, most welding operations for thin-walled hydraulic tubing components in the industry employ traditional external clamping methods. These methods only position the external parts of the tubing and cannot provide effective internal support. During welding, the high temperatures cause thermal expansion and contraction, and combined with the contraction force of the weld pool, the unsupported internal tubing wall is prone to irregular deformation. This deformation not only increases the workload and cost of subsequent correction processes but can also lead to tubing failure in severe cases, reducing production efficiency and product yield.

[0004] To address the shortcomings of the aforementioned technologies, we propose a deformation-resistant welding device for thin-walled hydraulic tubing components. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a deformation-resistant welding device for thin-walled hydraulic pipe components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A deformation-resistant welding device for thin-walled hydraulic hose components includes a welding table and a deformation-resistant welding auxiliary assembly. The deformation-resistant welding auxiliary assembly includes a support plate, which is fixedly installed on the upper side of the welding table. A turntable is rotatably installed on the inner side of the support plate. An electric telescopic rod is fixedly installed on the right side of the turntable, and a structural cylinder is fixedly installed on the left side of the turntable. The output end of the electric telescopic rod slides through into the inner side of the structural cylinder, and a pressure sensor is fixedly installed on the output end of the electric telescopic rod. A conical body is fixedly connected to the side of the pressure sensor. Several slots are formed on the side wall of the conical body. A sliding groove is formed on the side wall of the structural cylinder. A wedge-shaped slider is slidably arranged inside the sliding groove, and an outer arc abutment plate is fixedly connected to the outer wall of the wedge-shaped slider.

[0007] Furthermore, several connecting rods are fixedly installed on the inner inclined surface of the wedge-shaped slider, and a transverse locking post is fixedly installed at the end of the connecting rod, and the transverse locking post is slidably engaged in the inner side of the slot.

[0008] Furthermore, an end limiting plate is screwed onto the end of the conical body.

[0009] Furthermore, a geared disc is fixedly installed on the right side of the turntable, a drive motor is fixedly installed on the right side wall of the support plate, and a gear is fixedly installed on the output end of the drive motor, the gear meshing with the geared disc.

[0010] Furthermore, a protective cover is provided on the outer side of the right side of the turntable. The protective cover is screwed onto the right side wall of the support plate and covers the outside of the gear and the gear plate.

[0011] Furthermore, a thin-walled hydraulic oil pipe component is sleeved on the outer side of the structural cylinder, and several of the outer arc abutment plates abut against the inner wall of the thin-walled hydraulic oil pipe component.

[0012] Furthermore, a controller is fixedly installed on the upper side of the welding table, a side support plate is fixedly installed on the rear side of the welding table, an electric push rod is fixedly installed on the side support plate, and a welding torch is fixedly installed on the output end of the electric push rod.

[0013] Furthermore, a supplementary light is fixedly installed on the lower side of the side support plate.

[0014] Compared with related technologies, the anti-deformation welding device for thin-walled hydraulic pipe components proposed in this utility model has the following beneficial effects: In this utility model, a deformation-resistant welding device for thin-walled hydraulic pipe components is described. Through an auxiliary welding component designed to prevent deformation, a conical body with several slots is installed within a structural cylinder. These slots engage with transverse locking posts connected to the inner surface of a wedge-shaped slider slidably positioned within a groove. When the conical body slides inside the structural cylinder via an electric telescopic rod, the transverse locking posts and the inclined slots of the conical body slide against each other, causing the wedge-shaped slider to slide radially within the groove. This facilitates the contact of thin-walled hydraulic pipe components of different inner diameters fitted onto the outer side of the structural cylinder. The contacted thin-walled hydraulic pipe components, due to internal support, are less prone to deformation during welding, thus contributing to improved welding quality.

[0015] In addition, a pressure sensor is connected between the output end of the electric telescopic rod and the conical body. This sensor can monitor the magnitude of the longitudinal thrust applied by the electric telescopic rod to the conical body in real time, preventing excessive thrust that could cause the arc-shaped abutment plate on the outer side of the wedge-shaped slider to excessively abut against the inner wall of the thin-walled hydraulic oil pipe, resulting in abutment deformation. The longitudinal thrust applied by the electric telescopic rod can be controlled through the feedback of the pressure sensor to prevent abutment deformation. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Reference Figures 1-7 A deformation-resistant welding device for thin-walled hydraulic pipe components includes a welding table 1 and a deformation-resistant welding auxiliary component 3. The deformation-resistant welding auxiliary component 3 includes a support plate 31, which is fixedly installed on the upper side of the welding table 1. A turntable 32 is rotatably installed on the inner side of the support plate 31. An electric telescopic rod 37 is fixedly installed on the right side of the turntable 32, and a structural cylinder 38 is fixedly installed on the left side of the turntable 32. The output end of the electric telescopic rod 37 slides through to the inner side of the structural cylinder 38, and a pressure sensor 310 is fixedly installed on the output end of the electric telescopic rod 37. A conical body 311 is fixedly connected to the side of the pressure sensor 310. Several slots 312 are opened on the side wall of the conical body 311. A sliding groove 39 is opened on the side wall of the structural cylinder 38. A wedge-shaped slider 314 is slidably arranged inside the sliding groove 39. An outer arc abutment plate 315 is fixedly connected to the outer wall of the wedge-shaped slider 314.

[0020] In this method, a thin-walled hydraulic oil pipe component 4 is sleeved on the outer side of the structural cylinder 38, and several outer arc abutment plates 315 abut against the inner wall of the thin-walled hydraulic oil pipe component 4.

[0021] With the above-mentioned setup, before welding the thin-walled hydraulic pipe component 4, it is sleeved on the outside of the structural cylinder 38. The electric telescopic rod 37 drives several sets of outer arc abutment plates 315 to abut against the inner wall of the thin-walled hydraulic pipe component 4, which can stably sleeve it on the outside of the structural cylinder 38, and at the same time provide support for its interior, preventing deformation during welding.

[0022] In this method, a controller 2 is fixedly installed on the upper side of the welding table 1, a side support plate 5 is fixedly installed on the rear side of the welding table 1, an electric push rod 6 is fixedly installed on the side support plate 5, a welding gun 7 is fixedly installed on the output end of the electric push rod 6, and a supplementary light 8 is fixedly installed on the lower side of the side support plate 5.

[0023] With the above setup, the electric push rod 6 pushes the welding torch 7 close to the welding point on the thin-walled hydraulic oil pipe 4, and the welding process can begin once the welding torch 7 is started.

[0024] In this method, several connecting rods 316 are fixedly installed on the inner inclined surface of the wedge-shaped slider 314, and a transverse locking post 317 is fixedly installed at the end of the connecting rod 316. The transverse locking post 317 is slidably locked in the inner side of the slot 312, and an end limiting plate 313 is screwed to the end of the conical body 311.

[0025] With the above configuration, the wedge-shaped slider 314 establishes a sliding engagement relationship with the slot 312 on the side wall of the conical body 311 through the transverse locking post 317 on its inner side. When the electric telescopic rod 37 pushes the conical body 311 to slide inside the structural cylinder 38, the slot 312 will abut against the transverse locking post 317, pushing the wedge-shaped slider 314 to slide radially inside the sliding groove 39. Thus, the outer arc abutment plate 315 on the outer side of the wedge-shaped slider 314 can abut against the inner wall of the thin-walled hydraulic oil pipe 4 with different inner diameters.

[0026] In this configuration, a geared disc 34 is fixedly installed on the right side of the turntable 32, a drive motor 35 is fixedly installed on the right side wall of the support plate 31, and a gear 36 is fixedly installed on the output end of the drive motor 35, which meshes with the geared disc 34.

[0027] With the above-mentioned setup, during welding, by starting the drive motor 35, the gear 36 drives the gear disk 34 to rotate, which in turn drives the turntable 32 and the hydraulic oil pipe thin-walled component 4 sleeved on the outside of the structural cylinder 38 to rotate, forming a circumferential rotation welding effect of the hydraulic oil pipe thin-walled component 4, making the weld more continuous and improving the welding quality.

[0028] In this configuration, a protective cover 33 is provided on the outer side of the right side of the turntable 32. The protective cover 33 is screwed onto the right side wall of the support plate 31 and covers the outside of the gear 36 and the gear plate 34.

[0029] By setting it in the above manner, the protective cover 33 provides protection for the meshing space between the gear 36 and the gear disk 34.

[0030] The working principle of the anti-deformation welding device for thin-walled hydraulic pipe components provided by this utility model is as follows: Before welding the thin-walled hydraulic pipe component 4, the thin-walled hydraulic pipe component 4 is first fitted onto the outside of the structural cylinder 38 of the anti-deformation welding auxiliary component 3. Then, the electric telescopic rod 37 on the right side of the turntable 32 is started by the controller 2. The output end of the electric telescopic rod 37 pushes the pressure sensor 310 and the conical body 311 fixedly connected to it to slide inside the structural cylinder 38. Because the groove 312 on the side wall of the conical body 311 is slidably engaged with the transverse locking post 317 at the end of the inner connecting rod 316 of the wedge-shaped slider 314, when the conical body 311 slides, the inclined groove 312 will generate abutting thrust on the transverse locking post 317, causing the wedge-shaped slider 314 to slide radially along the sliding groove 39 of the structural cylinder 38 until the outer arc abutting plate 315 on the outer side of the wedge-shaped slider 314 is tightly abutted against the inner wall of the thin-walled hydraulic pipe 4. During this process, the pressure sensor 310 monitors the longitudinal thrust applied by the electric telescopic rod 37 in real time. When the thrust reaches the preset value, the controller 2 controls the electric telescopic rod 37 to stop moving, so as to avoid the outer arc abutting plate 315 from excessively squeezing the inner wall of the thin-walled hydraulic pipe 4 and causing deformation, thereby achieving stable internal support for the thin-walled hydraulic pipe 4 with different inner diameters. During welding, the electric push rod 6 on the side support plate 5 is activated by the controller 2. The electric push rod 6 pushes the welding torch 7 to the welding point of the thin-walled hydraulic pipe component 4. At the same time, the supplementary light 8 is turned on to provide sufficient illumination. Then, the drive motor 35 on the right side of the support plate 31 is activated. The output end of the drive motor 35 drives the gear 36 to rotate. The gear 36 meshes with the gear plate 34 on the right side of the turntable 32, thereby driving the turntable 32 and the structural cylinder 38 and the thin-walled hydraulic pipe component 4 fixed thereto to rotate synchronously. During the continuous rotation of the thin-walled hydraulic pipe component 4, the welding torch 7 continuously welds the part to be welded, forming a continuous weld. Meanwhile, the outer arc abutment plate 315 always provides stable support to the inner wall of the thin-walled hydraulic pipe component 4, effectively resisting the deformation caused by the high temperature of welding and the shrinkage force of the molten pool, and finally completing a high-quality welding operation.
