Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to automatic welding equipment for annular seams of hydraulic turning mechanism oil cylinders. Background Art

[0002] The working principle of the hydraulic flip machine is to rely on hydraulic oil as the power source, and send the hydraulic oil to both sides of the cylinder through the hydraulic pump, so that the piston on the cylinder generates a force to move up and down. This force is transmitted to the flip device through the lever mechanism to realize the flipping of the object.

[0003] Among them, the oil cylinder is the core component of the hydraulic turning mechanism. When two cylinder sections are formed into a complete oil cylinder body, it is often necessary to perform circumferential welding on the connection position of the two cylinder sections to form a stable oil cylinder body.

[0004] An automatic circumferential seam welding machine for water tank processing disclosed in a patent application with reference publication number CN209936157U is provided with a welding gas filtering structure to filter and absorb dust and harmful gases generated during the welding process in time, thereby reducing the content of welding dust and harmful gases in the air of the workshop, ensuring a healthy and clean working environment, thereby reducing the threat of welding exhaust gas to the health of workers; the shock-absorbing structure reduces the impact of vibration generated during the rotation of the water tank on the welding process, so that the welding head can more accurately fit the position where welding is required, thereby improving the welding accuracy, ensuring the quality of the product, and reducing the manufacturer's profit loss.

[0005] When welding the circumferential seam, most of the existing automatic welding equipment for circumferential seams use a clamping fixture to clamp and fix the two ends of the two workpieces to be welded. However, when the clamping fixture drives the workpiece to rotate, the weld position of the two workpieces is very likely to shake during the rotation process and cause position deviation, resulting in uneven welds and affecting the structural strength of the welding position. Secondly, under the high temperature of the welding gun, the metal around the weld is very likely to be melted by the high temperature, and the excess metal and oxide will accumulate on the weld to form burrs on the outer surface, which will not only affect the flatness of the weld and smoothness, and is also prone to tip stress concentration, which reduces the structural strength of the weld position. The weld position still needs to be polished before the next step of processing, thereby increasing the processing steps and workload; for example, a reference publication number CN209936157U is an automatic circumferential seam welding machine for water tank processing. The welding machine only clamps the two ends of the water tank, and the circumferential seam position to be welded is very likely to shake during the rotation of the water tank, resulting in the weld position being offset and misaligned, thereby causing an uneven weld, thereby affecting the structural strength of the welding position.

[0006] Therefore, the present invention proposes a hydraulic turning mechanism oil cylinder annular seam automatic welding device to solve the above problems. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides an automatic welding device for annular seams of hydraulic turning mechanisms and cylinders, which solves the problem that when the existing clamping tool drives the workpiece to rotate, the weld positions of the two sections of the workpiece are very likely to shake and shift during the rotation process, thereby causing an uneven weld and affecting the structural strength of the welding position. In addition, under the high temperature of the welding gun, the metal around the weld is very likely to be melted by the high temperature, and the excess metal and oxides will accumulate on the weld to form burrs on the outer surface, which will not only affect the flatness and smoothness of the weld, but also easily cause tip stress concentration, reduce the structural strength of the weld position, and still require post-grinding treatment of the weld position, thereby increasing the processing steps and workload.

[0018] The present invention provides a hydraulic turning mechanism oil cylinder annular seam automatic welding device. Compared with the prior art, it has the following beneficial effects: 1.

[0019] 2. A hydraulic turning mechanism cylinder annular seam automatic welding equipment is provided with a burr removal component. When the lifting component forms the bottom support for the cylinder barrel section, the burr removal component can be located just below the welded annular seam. It can cooperate with multiple contoured lifting components on both sides to form a simulated support for the cylinder barrel section. Moreover, while lifting and supporting the cylinder barrel section, the burr removal component can use a high-speed rotating grinding wheel to grind the annular seam position after welding, thereby removing metal burrs and welding slag generated by welding, making the weld position flat and smooth, avoiding the generation of tip stress concentration, and ensuring the connection strength of the weld position.

[0020] 3.

Next, two sections of the oil cylinder barrel sections to be welded are clamped in the No. 1 chuck 3 and the No. 2 chuck 5 respectively, and then the lifting mechanism 6 is pushed leftward or rightward along the outer wall of the slide 2, so that the bottom of the burr removal component 66 is directly opposite to the annular seam position of the two sections of the oil cylinder barrel sections. At this time, the top of the grinding wheel 668 is against the annular seam at the bottom of the two sections of the oil cylinder barrel sections; Next, the linear module 7 is started through the control box, and the linear module 7 drives the welding gun 8 to move according to the preset program until the welding gun 8 reaches the annular seam position at the connection between the two sections of the cylinder barrel. At this time, the motor has driven the No. 1 chuck 3 to rotate at a low and uniform speed, and the welding gun 8 continues to weld the rotating annular seam. At the same time, the motor 6610 drives the driven gear 669 to rotate through the driving gear 6611 and the toothed belt 6612, so that the transmission shaft 667 drives the grinding wheel 668 to rotate rapidly, and the burrs and welding slag generated by welding at the annular seam position are polished away by the grinding wheel 668, and the annular seam position is flat and smooth.
