Description

Technical Field

[0001] This invention belongs to the field of annular radiator welding technology, specifically the tooling and method for automatically rolling welding annular radiators. Background Technology

[0002] Currently, one method for welding corrugated plates in ring-shaped radiators is resistance roll welding. Roll welding requires one person to hold the product while welding, and due to the large number of corrugations—typically hundreds of weld seams—it is time-consuming and represents a bottleneck in the overall processing flow. For example... Figure 1 and Figure 2 The right side shows the roll welding equipment, which includes two roll welding wheels: an upper roll welding wheel and a lower roll welding wheel. The upper roll welding wheel is mounted on the upper support arm, and the lower roll welding wheel is mounted on the lower support arm.

[0003] To address the processing bottleneck in the roll welding of corrugated plates for ring radiators, free up labor, and ensure stable welding quality, there is an urgent need to design a tooling and method to assist in the automatic roll welding of ring radiators, replacing the existing method of manually holding the ring radiator to complete the welding. Summary of the Invention

[0004] The present invention aims to provide a tooling and method for automatically rolling welds annular radiators, thereby improving welding efficiency, saving manpower, ensuring efficient and high-quality welding, and being simple to operate and stable and reliable in the welding process.

[0005] To solve the above problems, the present invention adopts the following technical solution: A tooling for automatically rolling welds annular heat sinks includes: The water receiving box assembly is a shell with an open top and closed sides and bottom, and is located below the welding roller of the welding equipment. The frame assembly is located on the side of the water receiving box assembly away from the roll welding equipment. The frame assembly includes two horizontally parallel first tracks and a first base slidably connected to the first tracks. The axis of symmetry of the two first tracks is perpendicular to the plane where the roll welding wheels are located in the roll welding equipment and intersects the line connecting the rotation center points of the two roll welding wheels. A rotatable turntable and a first drive motor for driving the turntable to rotate are provided on the upper end of the first base. A horizontal sliding assembly is connected to a turntable. Two parallel second tracks are arranged on the horizontal sliding assembly along the vertical direction. A second base is slidably connected to the second tracks, and a second drive motor is arranged on the second base. A rotating assembly includes a bracket rotatably connected to a second base. At least three support arms are slidably disposed on the side of the bracket away from the second base. The multiple support arms are distributed on the same cylindrical surface at positions corresponding to different generatrices. The central axis of the cylindrical surface coincides with the rotation axis of the bracket, and the sliding path of the multiple support arms is located radially from the bottom surface of the cylindrical surface. The auxiliary support components are arranged symmetrically about the lower welding roller on the lower support arm of the welding equipment. Each auxiliary support component has multiple rotatable spherical supports at its upper end. A guide roller assembly, comprising a first guide pressing roller disposed at the front end of the upper roller welding roller, and a second guide pressing roller disposed at the rear end of the upper roller welding roller; A positioning vision component is disposed at the front end of the upper welding roller and the first guide clamping roller.

[0006] As one embodiment, the vertical height of the water receiving box assembly on the side away from the frame assembly is greater than the vertical height on the side closer to the frame assembly, such that the bottom of the water receiving box assembly includes a slope.

[0007] As one embodiment, the horizontal sliding assembly includes a lifting frame, two second rails mounted on the lifting frame, the lower end of the lifting frame connected to a turntable, and a first hydraulic cylinder for driving the second base to slide at the upper end of the lifting frame.

[0008] In one embodiment, the rotating assembly is connected to the second base via a slewing bearing shaft. A bearing is mounted on the slewing bearing shaft, and a gear ring is mounted on the outer ring of the bearing. The gear ring is fixed on the bracket and meshes with the gear at the output end of the second drive motor.

[0009] As one option, the frame assembly is provided with a lead screw for driving the first base to slide.

[0010] As one embodiment, the auxiliary support assembly includes a fixing plate, which is installed on the side of the lower support arm where the lower welding roller is located. The fixing plate is equipped with a spherical support mounting seat that can be raised and lowered. Multiple spherical supports are arranged on the spherical support mounting seat along the plane perpendicular to the lower welding roller.

[0011] As one solution, the tooling for automatically rolling and welding ring-shaped heat sinks also includes a loading buffer assembly for stacking ring-shaped heat sinks, which is located on one side of the frame assembly.

[0012] Furthermore, the lower end of the feeding buffer component is slidably connected to the third track, and the third track is perpendicular to the first track; or, the lower end of the feeding buffer component is provided with a roller.

[0013] As one option, the guide roller assembly also includes a second hydraulic cylinder and a third hydraulic cylinder for driving the first guide pressing roller and the second guide pressing roller to move.

[0014] A method for facilitating automatic roll welding of a ring-shaped heatsink, employing the aforementioned fixture with a feeding buffer assembly, includes the following steps: Step 1: Place the annular heat sink with the corrugated plate tack welded onto the feeding buffer assembly; Step 2: The first base drives the horizontal sliding component to move along the first track to the feeding buffer component, rotates the turntable and raises and lowers the second base so that the rotating component connected to the second base is facing the annular heat sink. Step 3: Adjust the position of multiple support arms so that the outer diameter of the outer circle of the multiple support arms is smaller than the inner diameter of the inner cylinder of the annular radiator. At this time, move the annular radiator toward the support arms and let the multiple support arms enter the inner cylinder of the annular radiator. Adjust the position of the multiple support arms again so that the multiple support arms are close to the inner cylinder wall of the annular radiator. Then rotate the turntable so that the axis of the annular radiator is perpendicular to the plane where the two welding wheels are located. Step 4: Move the horizontal sliding component to drive the annular heat sink toward the upper and lower welding rollers. When the annular heat sink approaches the upper and lower welding rollers, raise and lower the height of the second base so that the corrugated plate to be welded on the annular heat sink enters the gap between the upper and lower welding rollers. Step 5: Activate the positioning vision component, and adjust the position of the annular radiator by coordinating the horizontal movement of the horizontal sliding component and the rotation of the rotation component. When the positioning vision component identifies the position of the corrugated plate to be welded, it retracts multiple support arms to disengage the support arms from the inner wall of the annular radiator. At this time, the annular radiator is in a free state, with only the inner wall in contact with the spherical support and the lower welding roller of the auxiliary support component. Step 6: Activate the guide pressure roller assembly. The first and second guide pressure rollers press against the troughs corresponding to the positions of the corrugated plates to be welded on the annular radiator. Move the upper roller welding roller to begin roller welding. Step 7: After completing the welding of one ring of corrugated plate channels, extend multiple support arms so that the support arms are close to the inner wall of the annular radiator. Then repeat steps 5 and 6 to complete the welding of the next ring of corrugated plate channels. Repeat this process until all channels on the corrugated plate are welded.

[0015] Compared with existing technologies, this invention automates the roll welding of corrugated plates for annular radiators, replacing the traditional manual welding method, significantly improving the efficiency of resistance roll welding of annular radiators, and ensuring the consistency of welding quality.

[0016] Compared with the prior art, the present invention has the following characteristics: (1) The combined use of the guide roller assembly and the auxiliary support assembly achieves external pressure and internal support, ensuring that the corrugated plate will not shift during welding, thus guaranteeing stable and consistent welding quality; (2) The combined use of the frame assembly, horizontal sliding assembly and rotating assembly realizes the automation requirements of loading, transferring and welding position adjustment of the ring radiator, saving manpower; (3) The mature positioning vision component is used in conjunction with the displacement sensor to accurately identify the position of the corrugated plate to be welded, so as to ensure the consistency and stability of welding.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] like Figures 1-11As shown, this invention provides a tooling for automatically rolling and welding annular radiators, comprising a feeding buffer assembly 3, a guide roller assembly 4, a positioning vision assembly 5, an auxiliary support assembly 6, a water receiving box assembly 7, a horizontal sliding assembly 8, a frame assembly 9, and a rotating assembly 10.

[0020] The tooling for automatically rolling and welding ring-shaped heat sinks, as described in this invention, is designed according to the following method: 1. Based on the diameter and height (1:1 digital model) of the annular radiator 2, the site layout, and the height (1:1 digital model) of the roll welding equipment 1, an auxiliary automatic roll welding fixture frame assembly 9 was designed using NX 3D software. Taking the roll welding point of the annular radiator 2 as the reference, the tooling and the two electrodes of the roll welding equipment 1 are kept consistent in terms of axis (midpoint of the line connecting the rotation center of the upper roll welding wheel and the rotation center of the lower roll welding wheel), flatness (the frame assembly 9 and the roll welding equipment 1 are kept on the horizontal plane), and verticality. 2. Based on the diameter of the annular radiator 2 and the size of the lower support arm where the lower welding wheel of the welding equipment 1 is located, design the auxiliary support assembly 6; based on the maximum height of the annular radiator 2 and the highest point of the lower welding wheel of the welding equipment 1 as the horizontal reference, ensure that the annular radiator 2 remains horizontal between the fulcrums formed by the two auxiliary support assemblies 6 after installation. The auxiliary support assembly 6 is connected by screws, and the spherical support can rotate freely 360°. 3. Based on the number of corrugated plates to be welded in the annular radiator 2, the spacing between the crests and troughs, and the width of the upper and lower support arms of the roll welding equipment 1, and in combination with the requirements of the roll welding process, design the rotating component 10, and select the corresponding servo motor and limiter size according to the weight and rotation speed of the annular radiator 2. 4. Based on the individual waveform dimensions of the corrugated plate of the annular radiator 2 and the techniques of manual welding, the guide pressure roller assembly 4 was designed using the principle of contouring. It includes a first guide pressure roller and a second guide pressure roller, one in front of the upper welding roller and one behind it. According to the weld quality requirements and the height of the corrugated plate, the width, diameter and other dimensions of the first guide pressure roller and the second guide pressure roller were calculated. The material selected is H62 copper alloy. The center of the two welding rollers of the welding equipment 1 is used as the installation reference. 5. Based on the height of the ring radiator 2 and the reserved dimensions of the factory, the horizontal sliding component 8 and the rotating component 10 are designed. According to the weight and rotation speed of the ring radiator 2, the corresponding servo motor and limiter dimensions are selected, with the upper end face of the lower welding wheel of the welding equipment 1 as the reference. 6. Based on the welding characteristics of the roll welding equipment 1 and the cooling requirements of the electrodes (upper and lower roll welding wheels), the product diameter and the characteristics of the splashing range, a water receiving box assembly 7 was designed, with an outlet added to the lowest surface, and the material selected is rust-resistant aluminum alloy. 7. Based on the roll welding process, cycle design, and the shape of the ring radiator 2, a loading station is reserved. The loading buffer component 3 is designed according to the diameter and arc size of the ring radiator 2. The contact position with the ring radiator 2 is a plastic pad, and the rest are made of carbon steel. 8. Based on the characteristics and parameters of resistance roll welding, the materials of the guide roller assembly 4, horizontal sliding assembly 8, auxiliary support assembly 6 and rotating assembly 10 should avoid magnetic materials. According to the waveform, quantity and process requirements of the welding sequence, a displacement sensor (to collect the displacement of the corrugated plate) and a positioning vision assembly 5 (Cognex 7802 is selected in this embodiment) are added. 9. Based on the characteristics of automatic roll welding, the moving distance, and the control system of roll welding equipment 1, the automatic roll welding fixture and equipment data communication of the ring radiator 2 are integrated; PLC programming is used to control the start and stop of the roll welding equipment and the matching of fixture movement to facilitate automatic welding. 10. Select the appropriate auxiliary electrical control and standard connectors according to the relevant GB standards, and finally design the expansion bolt fixing fixture on the ground according to the load.

[0021] like Figures 1-4 The diagram shows the layout of the tooling for automatically rolling welds of annular radiators in the factory, the rolling welding equipment 1, and the welding status.

[0022] like Figure 5 As shown, the feeding buffer component 3 serves as a buffer and feeding reference. Multiple pads are provided on its upper surface to support the annular heat sink 2. The lower end of the feeding buffer component 3 uses a track to move closer to and further away from the frame component 9. like Figure 6 The diagram shows the installation position of the upper welding roller and the guide pressure roller assembly 4. The guide pressure roller assembly 4 includes a first guide clamping roller and a second guide clamping roller located in front of and behind the upper welding roller. The first guide clamping roller and the second guide clamping roller are driven by independent hydraulic cylinders to clamp the troughs of the corrugated plate. The rollers at the ends of the first guide clamping roller and the second guide clamping roller can rotate freely to achieve the guiding function. A displacement sensor and a positioning vision component 5 are also designed on one side of the first guide clamping roller to achieve accurate positioning of the corrugated plate to be welded. like Figure 7 As shown, this is auxiliary support component 6. The two auxiliary support components 6 are arranged according to... Figure 4 The positions shown are symmetrically installed on both sides of the lower support arm of the roll welding equipment 1. The auxiliary support assembly 6 includes a fixing plate, which is installed on the side of the lower support arm where the lower roll welding wheel is located. A spherical support mounting seat is flexibly mounted on the upper end of the fixing plate. The spherical support mounting seat achieves its lifting function through a guide shaft and a bushing. Three spherical supports are spaced at intervals along a direction perpendicular to the plane where the lower roll welding wheel is located on the upper end of the spherical support mounting seat. Figure 7The uppermost spherical surface is used as an auxiliary support point for roll welding. The height of the spherical support is adjusted according to the different inner diameters of the annular radiator 2 to ensure that the annular radiator 2 is in a horizontal state relative to the roll welding point during roll welding. The auxiliary support component 6 meets the support requirements for horizontal and circumferential movement of the annular radiator 2 during the welding process. like Figure 8 Based on the welding characteristics of the roller welding equipment 1 and the cooling requirements of the upper and lower roller welding wheels, a water receiving box assembly 7 with a slope was designed to prevent cooling water from dripping onto the tooling and the ground. like Figure 9 The horizontal sliding assembly 8 is connected to the turntable 903. Two parallel second tracks are arranged on the horizontal sliding assembly 8 along the vertical direction. A second base 801 is slidably connected to the second tracks. A second drive motor 802 is arranged on the second base 801. The output shaft of the second drive motor 802 has a gear. The horizontal sliding assembly 8 also includes a lifting frame 803. The two second tracks are installed on the lifting frame 803. The lower end of the lifting frame 803 is connected to the turntable 903. A first hydraulic cylinder for driving the second base 801 to slide vertically up and down is installed on the upper end of the lifting frame 803. like Figure 10 As shown, the frame assembly 9 is located on the side of the water receiving box assembly 7 away from the roll welding equipment 1. The frame assembly 9 includes two horizontally parallel first tracks 901 and a first base 902 slidably connected to the first tracks 901. The axis of symmetry of the two first tracks 901 is perpendicular to the plane where the roll welding wheels are located in the roll welding equipment 1 and intersects the line connecting the rotation center points of the two roll welding wheels. The upper end of the first base 902 is provided with a rotatable turntable 903 and a first drive motor 904 for driving the turntable 903 to rotate. like Figure 11As shown, the rotating assembly 10 includes a bracket 101, which is rotatably connected to the second base 801. Three support arms 102 are slidably disposed on the side of the bracket 101 away from the second base 801. The three support arms 102 are distributed on the same cylindrical surface, corresponding to three different generatrices. The central axis of the cylindrical surface coincides with the rotation axis of the bracket 101, and the sliding path of the three support arms 102 is radially along the bottom surface of the cylindrical surface. The bracket 101 is connected to the second base 801 via a slewing bearing shaft. A bearing is mounted on the slewing bearing shaft, with the outer ring of the bearing assembled with the inner ring of a gear ring. The gear ring is fixed to the bracket 101 and meshes with the gear at the output end of the second drive motor 802. Three hydraulic cylinders are provided on the bracket 101, which are used to drive the three support arms 102 to retract or expand radially. The three support arms 102 of the rotating assembly 10 are mainly used to support the inner cylinder of the annular radiator 2, thereby realizing the translation and rotation of the annular radiator 2 and assisting in adjusting the annular radiator 2 to a suitable welding position. During welding, the support arm 102 retracts and waits for the next weld. After each weld is completed on a ring of channels on the corrugated plate, the support arm 102 expands to support the annular heat sink 2. In conjunction with the displacement sensor and the positioning vision component 5, the support arm 102 locates the starting point of the next weld and rotates and translates to the positioning point. At the same time, the support arm 102 retracts inward, placing the annular heat sink 2 between the upper and lower welding rollers of the welding equipment 1. The annular heat sink 2 is in a free state (i.e., freely suspended on the spherical support of the lower welding roller and the auxiliary support component 6). The annular heat sink 2 is carried by the upper and lower welding rollers to complete the welding of one ring of channels, and then cycles to the next channel.

[0023] The method for facilitating automatic roll welding of a ring-shaped heatsink uses the aforementioned fixture with a feeding buffer component 3 and includes the following steps: Step 1: Place the annular heat sink 2 with the corrugated plate positioning weld completed on the feeding buffer assembly 3. The corrugated plate has been formed with the same curvature as the annular heat sink 2. The corrugated plate is composed of crests and troughs. The corrugated plate is manually positioned on the surface of the annular heat sink 2 in advance, and then the troughs are welded to form an integral part. In this embodiment, there are a total of 4 corrugated plates, and each corrugated plate has multiple annular channels. Step 2: The first base 902 drives the horizontal sliding component 8 to move along the first track 901 to the feeding buffer component 3, rotates the turntable 903, and raises and lowers the second base 801 so that the rotating component 10 connected to the second base 801 is facing the annular heat sink 2. Step 3: The position of the three support arms 102 is retracted by the hydraulic cylinder so that the outer diameter of the outer circle of the three support arms 102 is smaller than the inner diameter of the inner cylinder of the annular radiator 2. At this time, the feeding buffer assembly 3 is slid along the third track below the feeding buffer assembly 3 to move the annular radiator 2 toward the support arms 102 and make the three support arms 102 enter the inner cylinder of the annular radiator 2. The position of the three support arms 102 is expanded outward by the hydraulic cylinder so that the three support arms 102 are close to the inner cylinder wall of the annular radiator 2. Then the turntable 903 is rotated so that the axis of the annular radiator 2 is perpendicular to the plane where the two welding wheels are located. Step 4: Move the horizontal sliding component 8 to drive the annular heat sink 2 toward the upper and lower welding rollers. When the annular heat sink 2 approaches the upper and lower welding rollers, raise and lower the height of the second base 801 so that the position of the corrugated plate to be welded on the annular heat sink 2 enters the gap between the upper and lower welding rollers. Step 5: Activate the positioning vision component 5, and adjust the position of the annular radiator 2 in conjunction with the horizontal movement of the horizontal sliding component 8 and the rotation of the rotation component 10. When the positioning vision component 5 identifies the position of the corrugated plate to be welded, retract the three support arms 102 so that the support arms 102 are disengaged from the inner wall of the annular radiator 2. At this time, the annular radiator 2 is in a free state, and only the inner wall is in contact with the spherical support and the lower roller of the auxiliary support component 6. Step 6: Start the guide pressure roller assembly 4. The first guide pressure roller and the second guide pressure roller press against the troughs corresponding to the positions of the corrugated plates to be welded on the annular radiator 2. Move the upper roller welding roller to start the roller welding. Step 7: After completing the welding of one ring of corrugated plate channels, extend the three support arms 102 so that the support arms 102 are in close contact with the inner wall of the annular radiator 2. Then repeat steps 5 and 6 to complete the welding of the next ring of corrugated plate channels. Repeat this process until all channels on the corrugated plate are welded. Step 8: After completing the welding of all corrugated plate positions, the annular radiator 2 is moved to the designated position by rotating component 11 in conjunction with horizontal sliding component 8, and then reset before welding the next annular radiator 2.
