Description

TECHNICAL FIELD

[0001] The utility model belongs to mechanical technical field relates to a kind of steel member welding equipment. BACKGROUND

[0002] The welding of steel member is a kind of heating, high temperature or high pressure way to join metal and other materials to form stable structure processing technology, is widely used in construction, bridge, shipbuilding, automobile industry and multiple fields.

[0003] When the existing steel member is combined and installed, the sleeve is sleeved outside the steel pipe, and welding is carried out at the connecting part between the sleeve and the steel pipe. The traditional steel member welding is operated manually, but the operator's skill is required. The existing steel member welding equipment usually adopts welding gun fixing, and the combination of sleeve and steel pipe is rotated to carry out welding. In the process of rotation, the sleeve and the steel pipe are not positioned stably, dislocation occurs, or the force generated by rotation directly acts on the welding point, causing cracking and damage, which affects the welding effect and the quality of steel member. UTILITY MODEL CONTENTS

[0004] The utility model aims at the above-mentioned problems existing in prior art, and provides a kind of steel member welding equipment with stable positioning and good welding effect.

[0005] The utility model can be realized by the following technical schemes:

[0006] A kind of steel member welding equipment, including base and welding mechanism, the welding mechanism includes welding machine and welding gun, it is characterized in that, lifting platform is provided on the base, the center of upper part of lifting platform is connected with support rod, adjustable positioning mechanism is connected on the upper end of support rod, annular electric guide rail is provided on the outer side of lifting platform, the center axis of lifting platform coincides with the center axis of annular electric guide rail, sliding block is slidably connected on annular electric guide rail, fixed plate is connected above sliding block, welding machine is connected on fixed plate, welding gun support is connected on the upper part of one end of fixed plate close to lifting platform, welding gun is connected on welding gun support.

[0007] This steel component welding equipment uses an adjustable positioning mechanism to fix the weldment, which is composed of steel pipes and sleeves. This mechanism can be adjusted according to different weldment sizes to ensure stable positioning. A lifting platform provides support for the weldment, moving it vertically and adjusting its height to ensure the welding point aligns with the welding torch. Simultaneously, a slider and a circular electric guide rail work together to rotate the welding machine and welding torch around the weldment for welding. The working principle of the slider and circular electric guide rail is existing technology and will not be elaborated here. During this process, the weldment remains stationary, reducing the risk of misalignment and cracking. Furthermore, an external controller controls the slider to move at a suitable and uniform speed on the circular electric guide rail, improving the continuity and uniformity of the weld points and enhancing the welding effect and product quality.

[0008] In the aforementioned steel component welding equipment, the lifting platform includes a hydraulic cylinder and a support plate. The hydraulic cylinder is connected to the base, and the support plate is connected to the upper part of the piston rod of the hydraulic cylinder.

[0009] The support plate provides stable support for the weldment, and the extension and retraction of the piston rod of the hydraulic cylinder can drive the support plate to move up and down, thereby flexibly adjusting weldments of different specifications to the appropriate height.

[0010] In the aforementioned steel component welding equipment, there are several hydraulic cylinders, which are arranged in a rectangular array.

[0011] Several hydraulic cylinders can improve the stability and balance of lifting.

[0012] In the aforementioned steel component welding equipment, the adjustable positioning mechanism includes hydraulic cylinders and positioning plates. There are several hydraulic cylinders, which are arranged in a circumferential array on the outer side of the upper end of the support rod. The positioning plate is an arc-shaped plate, and the number of positioning plates is equal to that of the hydraulic cylinders. The positioning plates are connected one-to-one to the piston rod ends of the hydraulic cylinders.

[0013] The second hydraulic cylinder drives the positioning plate to move outward and close to the weldment until it is tightly pressed against the inner wall of the weldment. The simultaneous pressing of several positioning plates against the weldment increases the force-bearing area, thereby stabilizing the weldment.

[0014] In the aforementioned steel component welding equipment, buffer pads are provided on the outer sides of several of the positioning plates.

[0015] The buffer pad acts as a buffer between the positioning plate and the weldment, preventing damage caused by rigid contact between the positioning plate and the weldment, and also increasing the positioning stability of the weldment.

[0016] In the aforementioned steel component welding equipment, the upper surface of the support plate is provided with an anti-slip pad.

[0017] The workpiece is placed on the support plate, and the anti-slip pad between the workpiece and the support plate enhances the frictional resistance, further improving the positioning stability of the workpiece and preventing damage caused by rigid contact between the workpiece and the support plate.

[0018] The aforementioned steel component welding equipment also includes a guide rail frame, which is connected to the base, and the annular electric guide rail is connected to the guide rail frame.

[0019] The guide rail bracket securely connects the circular electric guide rail to the base, ensuring operational stability.

[0020] In the aforementioned steel component welding equipment, both the buffer pad and the anti-slip pad are made of rubber.

[0021] Compared with existing technologies, this steel component welding equipment offers high positioning stability for the weldment, which helps improve welding accuracy. Furthermore, the method of fixing the weldment and rotating the welding torch around it improves the continuity and uniformity of the welding process, reduces the risk of weldment misalignment and welding cracking, enhances the welding effect, and improves product quality. The adjustable positioning mechanism and lifting platform can adapt to welding work on weldments of different specifications, making it widely applicable and easy and flexible to operate.
