Abstract

A circular water-cooled welding auxiliary device includes a central shaft and tapered roller bearings, a thrust bearing, a swing arm, a connecting rod and connecting rod pin, an arc-shaped cover plate, a conformal water jacket, a swing arm cylinder, and a rotary cylinder. A combined circular component, tightly fitted together with a circular rim and a circular flange, is placed on this device. The circular rim is locked in place by the rotating motion of multiple rotary cylinders. The swing arm cylinder drives the swing arm, connecting rod, arc-shaped cover plate, and conformal water jacket to move synchronously in opposite directions, automatically centering and clamping them. Coolant can freely flow in and out of the conformal water jacket through an external cooler, effectively circulating the coolant. During welding, the coolant cools the welding area, removing the heat generated during welding and maintaining a stable temperature.

Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically a circular water-cooled welding auxiliary device. Background Technology

[0002] With the continuous and rapid development of the automotive manufacturing industry, especially in the fields of new energy, new materials, and intelligent manufacturing, the emphasis on personalization has enabled the design of two- or three-piece combined circular automotive parts to be varied, making them easy to customize. This will lead to wider applications, a broader market, and a richer application background.

[0003] Currently, most modular circular automotive sports components are modified aluminum alloy forged parts, consisting of several parts such as a circular rim, circular spokes, and circular bushings, which are tightened together and fixed with adhesive using specialized high-strength bolts. While these bolt-fitted circular automotive sports components can be matched and combined to create various styles and specifications, providing convenience for car owners who want to express their individuality, they have disadvantages. The manufacturing process is complex, the cost is high, and the selling price is relatively high. Circular automotive components have significant weight and inertia, making them heavy. Furthermore, the complex manufacturing process makes them prone to deformation and cracking. Dynamic balancing is poor, and assembly requirements are high. Moreover, the use of high-strength bolts makes it difficult to ensure product consistency, resulting in tightening defects. Currently, production is limited to a single product type, with a slow production cycle and low efficiency, posing potential safety risks to ensuring vehicle safety and performance.

[0004] A modular circular component welding device uses welding to fit a circular rim and a circular web together with an interference fit. The connection between the circular web and the rim is then welded together to form a complete circular component. This allows the circular rim to be reused; different shapes can be achieved simply by changing the circular webs, making it very convenient and efficient.

[0005] In the welding process of modular circular components, the heat generated during welding is very difficult to control. High welding current and high heat can easily lead to burn-through, undercut, pitting, collapse, and even melt-through and excessive back penetration. Low welding current and low heat can easily result in incomplete fusion and incomplete penetration, especially in areas of stress concentration, which can easily lead to cracks. The weld strength and sealing performance are both substandard, resulting in poor weld quality. How to reasonably and effectively control the welding temperature has become a technical challenge hindering the widespread development of welding modular circular components. Summary of the Invention

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0037] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] The following is for reference. Figures 1 to 2 The circular water-cooled welding auxiliary device of the present invention is described in conjunction with the embodiments.

[0039] A circular water-cooled welding auxiliary device includes: a circular base plate 100, left I support plate 101, left II support plate 102, right I support plate 103, right II support plate 104, a central thrust bearing 105, a first rotary cylinder mounting plate 106, a second rotary cylinder mounting plate 107, a third rotary cylinder mounting plate 108, and a third rotary cylinder mounting plate 109, a central shaft 110, left I bracket 111, left II bracket 112, right I bracket 113, and right II bracket 114, left I guide rail slider 115, left II guide rail slider 116, right I guide rail slider 117, and right II guide rail slider 118, a left arc-shaped cover plate 119, a right arc-shaped cover plate 120, and a left I linear guide rail. 121. Rail 122. Left II linear guide rail 123. Right I linear guide rail 124. Right II linear guide rail 125. Tapered bearing cover 125. I rotary cylinder 126. II rotary cylinder 127. III rotary cylinder 128. IIII rotary cylinder 129. Polyurethane center support 130. Conical locking nut 131. Left arc support 132. Left arc contour water jacket 133. Right arc support 134. Right arc contour water jacket 135. Left swing arm cylinder 136. Right swing arm cylinder 137. Left connecting rod 138. Right connecting rod 139. Center swing arm 140. Left connecting rod pin 141. Right connecting rod pin 142. Left swing arm cylinder bracket 143. Right swing arm cylinder bracket 144.

[0040] like Figure 1 As shown, left I support plate 101, left II support plate 102, right I support plate 103, and right II support plate 104 are symmetrically fixed on the circular base plate 100, and I rotary cylinder mounting plate 106, II rotary cylinder mounting plate 107, III rotary cylinder mounting plate 108, and IIII rotary cylinder mounting plate 109 are symmetrically installed on the top, bottom, left, and right sides.

[0041] like Figure 2 As shown, a left I bracket 111 is installed on the left I support plate 101, and a left I guide rail slider 115 is installed on the top of the left I bracket 111.

[0042] A left I1 bracket 112 is mounted on the left II support plate 102, and a left II guide rail slider 116 is mounted on the top of the left II bracket 112. A right I bracket 113 is mounted on the right I support plate 103, and a right I guide rail slider 117 is mounted on the top of the right I bracket 113. A right II bracket 114 is mounted on the right II support plate 104, and a right II guide rail slider 118 is mounted on the top of the right I bracket 114.

[0043] Left arc-shaped cover plate 119 has left linear guide rail I 121 and left linear guide rail II 122 installed underneath. (Reference) Figure 1 Right arc-shaped cover plate 120 is fitted with right I linear guide rail 123 and right II linear guide rail 124.

[0044] (refer to Figure 1 )

[0045] Left I guide rail slider 115 cooperates with left I linear guide rail 121, left II guide rail slider 116 cooperates with left II linear guide rail 122, right I guide rail slider 117 cooperates with right I linear guide rail 123, and right II guide rail slider 118 cooperates with right II linear guide rail 124.

[0046] Rotary cylinder 126 is mounted on rotary cylinder mounting plate 106; rotary cylinder 127 is mounted on rotary cylinder mounting plate 107; rotary cylinder 128 is mounted on rotary cylinder mounting plate 108; and rotary cylinder 129 is mounted on rotary cylinder mounting plate 109. Each of these four rotary cylinders has a contour gripper mounted on its rotating arm. When the rotary cylinder solenoid valve is energized, the rotary cylinder actuates, and compressed air guides the cylinder piston in a linear reciprocating motion. The rotating arm of the rotary cylinder rotates 90 degrees around the cylinder's axis, ensuring smooth operation of the contour gripper mounted on the rotating arm.

[0047] All rotary cylinders are magnetic ring cylinders. A magnetic switch is installed on the outer wall of the cylinder to detect the position of the cylinder piston. The control program system collects the magnetic switch signal to determine whether the rotary cylinder is in the open or closed state.

[0048] The circular rim is locked in place by the rotating action of multiple rotary cylinders. The swing arm cylinder drives the swing arm, connecting rod, arc-shaped cover plate, and contoured water jacket to move synchronously in opposite directions, completing the automatic centering and clamping.

[0049] like Figure 3As shown, one end of the central swing arm 140 is connected to the left connecting rod 138. The other end of the central swing arm 140 is connected to the right connecting rod 139. The left swing arm cylinder 136 is connected to the circular base plate 100 through the left swing arm cylinder bracket 143, and the cylinder rod end of the left swing arm cylinder 136 is connected to one side of the central swing arm 140 through a cylinder movable joint. The right swing arm cylinder 137 is connected to the circular base plate 100 through the right swing arm cylinder bracket 144, and the cylinder rod end of the right swing arm cylinder 137 is connected to the other side of the central swing arm 140 through a cylinder movable joint.

[0050] The left connecting rod 138 is connected to the left arc-shaped cover plate 119 via the left connecting rod pin 141. A left arc-shaped support 132 is installed on the left arc-shaped cover plate 119, and a left arc-shaped water jacket 133 is installed inside the left arc-shaped support 132.

[0051] The right connecting rod 139 is connected to the right arc-shaped cover plate 120 via the right connecting rod pin 142. A right arc-shaped support 134 is installed on the right arc-shaped cover plate 120, and a right arc-shaped water jacket 135 is installed inside the right arc-shaped support 134.

[0052] The left arc-shaped water jacket 133 and the right arc-shaped water jacket 135 are made of copper and have extremely high thermal conductivity.

[0053] The left swing arm cylinder 136 and the right swing arm cylinder 137 move synchronously. The extension and retraction of the cylinder rods of the left swing arm cylinder 136 and the right swing arm cylinder 137 drive the central swing arm 140, the left connecting rod 138, and the right connecting rod 139 to move synchronously in opposite directions around the central axis 110 of the device.

[0054] At the same time, the left connecting rod 138 drives the left arc-shaped cover plate 119, the left arc-shaped support 132, and the left arc-shaped water jacket 133 through the left connecting rod pin 141, and slides horizontally along the left I guide rail slider 115 and the left II guide rail slider 116 respectively.

[0055] The right connecting rod 139 drives the right arc-shaped cover plate 120, the right arc-shaped support 134, and the right arc-shaped water jacket 135 via the right connecting rod pin 142. These components slide horizontally along the right I guide rail slider 117 and the right II guide rail slider 118, respectively, along the right I linear guide rail 123 and the right II linear guide rail 124.

[0056] The extension and retraction of the cylinder rods of the left swing arm cylinder 136 and the right swing arm cylinder 137 simultaneously complete the automatic opening and closing actions of the left arc-shaped cover plate 119, the left arc-shaped support 132, the left arc-shaped water jacket 133, the right arc-shaped cover plate 120, the right arc-shaped support 134, and the right arc-shaped water jacket 135.

[0057] Both the left swing arm cylinder 136 and the right swing arm cylinder 137 are magnetic ring cylinders. Magnetic switches are installed on the outer wall of the cylinder to detect the position of the cylinder piston. The control program system collects the magnetic switch signals to determine whether the left swing arm cylinder 136 and the right swing arm cylinder 137 are in the extended and retracted state, and to determine whether the synchronously operating left arc support 132, left arc contour water jacket 133 and right arc support 134 and right arc contour water jacket 135 are in the open or closed state.

[0058] like Figure 4 As shown, a central shaft 110 is mounted at the center point of the circular base plate 100. The bottom section of the central shaft 110 has a smooth boss structure to facilitate the installation of a tapered roller bearing for connection with the central rocker arm 140. The upper section of the smooth boss structure of the central shaft 110 has an external thread structure to facilitate connection with the internal thread structure on the tapered locking nut 131. The tapered locking nut 131 adopts an internal thread structure arranged coaxially with the central shaft 110, allowing the internal thread of the tapered locking nut 131 to engage with the external thread of the central shaft 110.

[0059] A tapered roller bearing cap 125, concentric with the central shaft 110 of the device, is installed outside the tapered roller bearing. This cap isolates external dust, aluminum shavings, dirt, grease, and other impurities, preventing them from entering the tapered roller bearing, protecting it from external environmental interference, reducing friction, ensuring normal bearing operation, and effectively extending the bearing's service life.

[0060] A central thrust bearing 105 is mounted on the tapered bearing cap 125, and a polyurethane central support 130 is mounted on the central thrust bearing 105. The polyurethane central support 130 is a polymer material with good resilience, oil resistance, wear resistance, and aging resistance. The polyurethane central support 130 can flexibly and stably contact the surface of the circular spokes, effectively preventing scratches on the contact surface of the circular spokes. The central thrust bearing 105 mainly bears the axial load, effectively supporting the weight of the circular spokes and rim, ensuring that the polyurethane central support 130 rotates freely under the loading condition of the circular spokes and rim.

[0061] like Figure 5 As shown,

[0062] First, loosen the tapered lock nut 131 by rotating it counterclockwise.

[0063] The extension of the cylinder rods of the left swing arm cylinder 136 and the right swing arm cylinder 137 simultaneously completes the automatic opening of the left arc-shaped cover plate 119, the left arc-shaped support 132, the left arc-shaped water jacket 133, the right arc-shaped cover plate 120, the right arc-shaped support 134, and the right arc-shaped water jacket 135. This forms a combined circular component with the circular rim and the circular radial body, which have been thermally expanded and press-fitted with an interference fit. After being flipped, the component passes through the central shaft 110 of the device and is installed on the polyurethane central support 130.

[0064] Rotary cylinder 126 (I), Rotary cylinder 127 (II), Rotary cylinder 128 (III), Rotary cylinder 129 (IIII)

[0065] When the solenoid valve is energized, the rotary cylinder is activated. The rotating arm of the rotary cylinder rotates 90 degrees around the cylinder's axis, causing the contour grippers installed on the rotating arm of the rotary cylinder to tightly lock the edge of the circular rim of the combined circular component.

[0066] At this point, rotate clockwise to tighten the conical locking nut 131, ensuring that the conical surface of the conical locking nut 131 is in close contact with the central hole of the circular body.

[0067] like Figure 6 As shown, the retraction of the cylinder rods of the left swing arm cylinder 136 and the right swing arm cylinder 137 simultaneously completes the horizontal movement and completes the full closure of the left arc-shaped cover plate 119, the left arc-shaped support 132, the left arc-shaped water jacket 133, the right arc-shaped cover plate 120, the right arc-shaped support 134, and the right arc-shaped water jacket 135. At this time, the left arc-shaped water jacket 133 and the right arc-shaped water jacket 135 are in a smooth and sealed closed state. The coolant can freely flow in and out inside the left arc-shaped water jacket 133 and the right arc-shaped water jacket 135, and the coolant is effectively circulated through an external cooler.

[0068] like Figure 7 As shown, the left arc-shaped water jacket 133 and the right arc-shaped water jacket 135 are in a smooth and sealed closed state, and the annular water jacket is tightly fitted to the weld connection between the circular body and the circular rim.

[0069] The coolant has a high specific heat capacity and heat capacity. When the coolant circulates through the welding area during welding, it absorbs the heat generated during welding, thereby reducing the temperature of the welding area and ensuring uniform heat distribution, avoiding localized overheating. This prevents overheating at the weld joint from causing deformation of the assembled circular components. It also makes welding assembled circular components easier and simpler, ensuring the integrity and reliability of the welded structure while achieving higher weld quality, making it more practical and suitable for mass production in workshops.

[0070] This circular water-cooled welding auxiliary device adopts a symmetrical mirror-image mechanical structure, including: a central shaft and tapered roller bearings, a thrust bearing, a swing arm, a connecting rod and connecting rod pin, an arc-shaped cover plate, a contoured water jacket, a swing arm cylinder, and a rotary cylinder. A combined circular component, tightly joined by a circular rim and a circular web with an interference fit, is placed on the circular water-cooled welding auxiliary device provided by this invention. The circular rim is locked in place by the rotating motion of multiple rotary cylinders. The swing arm cylinder drives the swing arm, connecting rod, arc-shaped cover plate, and contoured water jacket to move synchronously in opposite directions, automatically centering and clamping them. Coolant can freely flow in and out of the contoured water jacket through an external cooler, effectively circulating the coolant. During this process, a circumferential weld is performed at the tight junction of the circular rim and the circular web until they become a complete unit. During welding, the coolant cools the welding area, removing the heat generated during welding and maintaining a stable temperature.

[0071] The left and right arc-shaped water jackets are made of copper, which has extremely high thermal conductivity.

[0072] The coolant has a high specific heat capacity and heat capacity. During welding, the coolant is delivered to the heating areas of the weld fusion process through a cold liquid circulation system. After absorbing the welding heat, it is returned to the cold liquid tank for cooling. The continuous circulation of coolant cools the welding area. As the coolant circulates through the welding zone during welding, it absorbs the heat generated, thereby reducing the temperature of the welding area and ensuring uniform heat distribution, avoiding localized overheating. This prevents overheating at the weld joint, which could lead to deformation of the assembled circular components. It effectively prevents defects inherent in traditional welding processes and the difficulty in controlling the gradual temperature change during welding, which can lead to insufficient weld penetration, poor substrate bonding, lack of fusion, bubbles, inclusions, weld cracking, lamellar tearing, peeling, burn-through, undercut, and back penetration at the weld end face. Furthermore, it boasts high welding efficiency, achieving 100% duty cycle. It is durable and has excellent heat dissipation. It effectively reduces deformation and stress during welding, ensuring a good weld transition and guaranteeing the mechanical properties and stability of the weld area.

[0073] The polyurethane central support is made of a polymer material with excellent resilience, oil resistance, wear resistance, and aging resistance. The polyurethane central support can flexibly and stably contact the surface of the circular spokes, effectively preventing scratches on the contact surface. The central thrust bearing 105 mainly bears the axial load, effectively supporting the weight of the circular spokes and rim, ensuring the polyurethane central support rotates freely under load from the circular spokes and rim.

[0074] All cylinders are magnetic ring cylinders. A magnetic switch is installed on the outer wall of the cylinder to detect the position of the cylinder piston. The control program system collects the magnetic switch signal to determine whether the cylinder is in the open or closed state.

[0075] The circular rim is locked in place by the rotating action of multiple rotary cylinders. The swing arm cylinder drives the swing arm, connecting rod, arc-shaped cover plate, and contoured water jacket to move synchronously in opposite directions, completing the automatic centering and clamping.

[0076] According to the present invention, a circular water-cooled welding auxiliary device is provided, and the specific operation process is illustrated below:

[0077] First, through the touch screen window of the electronic control section, set the initialization cylinder magnetic switch detection position signal and peripheral device connection function detection signal, and then rotate counterclockwise to loosen the conical locking nut 131 and set it aside.

[0078] The program controls the movement of the left swing arm cylinder 136 and the right swing arm cylinder 137. As the swing arm cylinder rod extends, the left arc-shaped cover plate 119, the left arc-shaped support 132, the left arc-shaped water jacket 133, the right arc-shaped cover plate 120, the right arc-shaped support 134, and the right arc-shaped water jacket 135 are opened automatically. This facilitates material loading for operators.

[0079] At this point, the circular rim and the circular web, which have been thermally expanded and press-fitted with an interference fit, are combined into a circular component. After being flipped over, the component is installed on the polyurethane central support 130 through the central shaft 110 of the device.

[0080] When the solenoid valves of rotary cylinders I (126), II (127), III (128), and IIII (129) are energized, the rotary cylinders actuate. The rotating arms of the rotary cylinders rotate 90 degrees around the cylinder's axis, causing the contour grippers mounted on the rotating arms to tightly lock onto the edge of the circular rim of the modular circular component. This completes the automatic centering and clamping.

[0081] At this point, rotate clockwise to tighten the conical locking nut 131, ensuring that the conical surface of the conical locking nut 131 is in close contact with the central hole of the circular body.

[0082] After the material is loaded, the operator presses the equipment start button. The program controls the retraction of the cylinder rods of the left swing arm cylinder 136 and the right swing arm cylinder 137, simultaneously completing the automatic closure of the left arc-shaped cover plate 119, the left arc-shaped support 132, the left arc-shaped water jacket 133, the right arc-shaped cover plate 120, the right arc-shaped support 134, and the right arc-shaped water jacket 135. At this time, the left arc-shaped water jacket 133 and the right arc-shaped water jacket 135 of this circular water-cooled welding auxiliary device are in a smooth and sealed closed state. The coolant can freely flow in and out of the water jacket through the external cooler, and the coolant circulates effectively. The closed ring-shaped water jacket fits tightly against the position of the combined circular component that needs to be welded.

[0083] The welding power supply is started, the protective functions are activated, the coolant circulation equipment is started, and the protective gas pressure monitoring is activated. The coolant circulation equipment pumps the coolant into a closed, annular conformal water jacket, and the coolant begins to circulate.

[0084] During the welding process, the equipment program controls the flow of coolant through a cooling liquid circulation system to the heating areas where welding fusion occurs. The coolant absorbs the welding heat and is then returned to the cooling liquid tank for further cooling. This continuous circulation of coolant cools the welding area. As the coolant circulates through the welding zone during welding, it absorbs the heat generated, thus lowering the temperature of the welding area and ensuring even heat distribution to prevent localized overheating. This prevents overheating at the weld joint from causing deformation of the assembled circular component material.

[0085] Welding is complete. The program controls the left swing arm cylinder 136 and the right swing arm cylinder 137 to move. As the swing arm cylinder rod extends, the left arc-shaped cover plate 119, the left arc-shaped support 132, the left arc-shaped water jacket 133, the right arc-shaped cover plate 120, the right arc-shaped support 134, and the right arc-shaped water jacket 135 are automatically opened simultaneously. The program controls the solenoid valves of rotary cylinders I 126, II 127, III 128, and IIII 129 to be energized again. The rotary cylinders move, and the rotating arms of the rotary cylinders rotate in the opposite direction around the cylinder axis. This causes the contour grippers installed on the rotating arms of the rotary cylinders to completely release the edge of the circular rim of the combined circular component, allowing the welded combined circular component to be removed for a new round of welding.

[0086] The equipment's program system monitors its operation in real time, ensuring that critical operating parameters such as coolant pressure, coolant temperature, and cylinder pressure remain within reasonable set ranges, with no error alarms and a continuous, uninterrupted welding process. Through these logical actions, information storage and traceability are achieved, effectively preventing the leakage of defective products.
