Abstract
Description
Technical Field
[0001] This utility model mainly relates to the technical field of welding technology, specifically a multi-angle rivet spot welding device. Background Technology
[0002] Rivet spot welding equipment uses spot welding to firmly weld rivets onto workpieces, thereby achieving efficient connection of two or more components. This connection method is not only fast but also has high connection strength, which can meet various high-strength and high-reliability connection requirements. However, existing rivet spot welding equipment can usually only perform automated welding of rectangular welding points. Since the sheet metal that needs to be rivet spot welded is not always a regular rectangle, when spot welding irregularly shaped sheet metal, it is necessary to manually remove the sheet metal repeatedly to adjust the angle, which is time-consuming and labor-intensive.
[0003] According to application number 202010363030.4, a multi-angle spot welding device is provided, which uses multiple welding heads to spot weld the workpiece from multiple angles. At least one welding head includes a fixed component, a swinging component, and a welding head body. When the welding head body contacts the offset welding point, the welding head body will be subjected to the reaction force of the contact point. At the same time, since the fixed component maintains its original direction of movement under the drive of the welding head driving device, the entire welding head is subjected to the action of the welding head body and the first contact welding point. The swinging component swings towards the contact point through the connecting component, which enables spot welding of the workpiece from multiple angles at the same time. It can also automatically adjust the orientation of the welding head according to the shape of the workpiece to prevent incomplete welding and welding time difference, and ensure the accuracy of spot welding operation.
[0004] The aforementioned document describes how welding can be performed by adjusting the angle of the welding head, which can accommodate some irregular sheet metal parts. However, the degree of freedom in adjusting the welding point and welding angle is limited, making it unsuitable for most irregular sheet metal parts. Utility Model Content

The bottom plate of the E-shaped plate has a welded bottom tube on its top. A second threaded rod is rotatably mounted inside the upper half of the E-shaped plate. A second threaded sleeve is connected to the middle threaded nut of the second threaded rod. A second drive motor with its actuating end connected to the central shaft of the second threaded rod is mounted on the top of the E-shaped plate.
[0011] Preferably, the welding pipe is slidably inserted into the upper half of the E-shaped plate, and a connecting plate for connecting the second threaded sleeve is fixedly fitted in the middle of the welding pipe. A welding machine is installed on the top of the base on one side of the vertical plate, and the output port of the welding machine is connected to the welding pipe through a pressure-resistant hose.
[0012] Preferably, the drive rod has two gears at both ends that mesh with the external teeth of the semi-gear ring disk, a knob connected to one end of the drive rod is provided on one side of a support block, a second screw tube is provided at one end of the support block, a second extrusion screw is threaded inside the second screw tube, an arc-shaped groove is provided inside the semi-gear ring disk, and a roller that is rotatably fitted inside the arc-shaped groove is rotatably installed on one side of the limiting block.

The combination of these two components enables the application of workpieces of various complex shapes and sizes. The adjustable angle function after installation avoids the need for frequent removal of the sheet metal steel for position adjustments. This not only enhances the applicability and practicality of the riveting and welding device but also reduces adjustment time and improves production efficiency.

The approaching component, through components such as a second drive motor and a second threaded rod, achieves precise approach control of the welded pipe. This precise translation and approach control enables the device to automatically and accurately reach the designated spot welding position and perform effective spot welding operations. It can complete multiple spot welding operations in a short time, thus improving production efficiency. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] Example
[0025] Please refer to the attached document carefully. Figure 1 , 2As shown in Figures 3 and 4, a multi-angle rivet spot welding device includes a base 10. Two vertical plates 11 are fixedly installed on both sides of one end of the top of the base 10, and two support blocks 12 are fixedly installed on both sides of the other end of the base 10. A translation component 13 is rotatably installed in the middle of the two vertical plates 11, and a mounting plate 14 is movably installed in the middle of the translation component 13. A contact component 15 is rotatably installed at one end of the mounting plate 14, and a welding pipe 16 is slidably installed in the middle of the contact component 15. A support block 12 is rotatably installed in the middle of the support block 12. The device includes a drive rod 17. Each support block 12 has a limiting block 18 mounted on the top of the base 10 near the end of the vertical plate 11. A semi-gear ring disk 19 is rotatably mounted on the side of the limiting blocks 18 that are close to each other. Clamping components 20 are provided inside both ends of the semi-gear ring disk 19. The drive rod 17 has two gears 171 at both ends that mesh with the external teeth of the semi-gear ring disk 19. A knob 172 connected to one end of the drive rod 17 is provided on one side of each support block 12. A second screw tube 173 passes through one end of the support block 12. The second screw tube 173 is internally threaded with a second extrusion screw 174. The semi-gear ring 19 has an arc-shaped groove 191 inside. A roller 192, rotatably fitted into the arc-shaped groove 191, is rotatably mounted on one side of the limiting block 18. The clamping component 20 includes support columns 201 at both ends of the semi-gear ring 19. One support column 201 has a threaded groove 202 inside, and a long bolt 203 is connected to the threaded groove 202 via a nut. The long bolt 203 and the other support column 201 are mutually... A rubber pad 204 is fixedly installed at one end of each of the two sides; two threaded sleeves 141 of the first threaded rod 131 are welded to the upper and lower ends of one end of the mounting plate 14; two inclined plates 142 are welded to both sides of the mounting plate 14; an arc-shaped tube 143 is fixedly installed in the middle of the two inclined plates 142; a sliding tube 144 is sleeved on the outside of the arc-shaped tube 143; a first screw tube 145 is provided at the top of the sliding tube 144; and a first compression screw 146 is threaded inside the first screw tube 145.
[0026] As described above, the long bolt 203, the first pressing screw 146, and the second pressing screw 174 are all fitted with small rotating sleeves for easy rotation. The roller 192 and the gear 171 press against the semi-gear ring 19, allowing the semi-gear ring 19 to be supported and rotated by the gear 171. When a rivet spot welding operation is required on a sheet metal piece, first, the two ends of the sheet metal piece are placed in the middle of the two sets of support columns 201. The long bolt 203 is turned so that it descends in the threaded groove 202, causing a rubber pad 204 to descend. The two rubber pads 204 fix the two ends of the sheet metal piece. Then, according to the required spot welding angle of the sheet metal piece, the second pressing screw 174 is loosened. At this time, the drive rod 17 can be rotated by the knob 172. When the drive rod 17 rotates, it passes through the two gears 192 and 171. 71 drives the two semi-gear ring disks 19 to rotate back and forth. During rotation, the roller 192 on one side of the limiting block 18 rolls inside the arc groove 191 to limit the rotation of the semi-gear ring disk 19. When the semi-gear ring disk 19 drives the sheet metal to rotate to the required angle, the second pressing screw 174 is tightened again to lock the drive rod 17 and prevent the semi-gear ring disk 19 from deviating. Then, according to the required spot welding angle inside the sheet metal, the first pressing screw 146 in the first screw tube 145 is loosened to push the top of the E-type plate 151, so that the sliding tube 144 can slide along the arc tube 143, so that the E-type plate 151 can rotate left and right about the center of the mounting plate 14 to achieve another spot welding angle adjustment. After the angle is adjusted, the first pressing screw 146 is tightened again to prevent the E-type plate 151 from shaking.
[0027] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 3 and 5, the translation component 13 includes two first threaded rods 131 rotatably mounted on the middle of two vertical plates 11. A dual-output reducer 132 with two output ends connected to the two first threaded rods 131 is mounted on one side of the outer edge of one vertical plate 11. A first drive motor 133 is also mounted on one side of the outer edge of the vertical plate 11, with the actuator end of the first drive motor 133 connected to the input end of the dual-output reducer 132. The approach component 15 includes an E-type plate 151 rotatably mounted at one end of the mounting plate 14 and welded to the same end of the sliding tube 144 at the top. The bottom plate of the E-type plate 151 has a welded bottom tube 1 on its top. 52. A second threaded rod 153 is rotatably installed inside the upper half of the E-type plate 151. A second threaded sleeve 154 is connected to the middle of the second threaded rod 153 by a nut. A second drive motor 155 is installed on the top of the E-type plate 151, with the execution end connected to the central shaft of the second threaded rod 153. The welding pipe 16 is slidably inserted inside the upper half of the E-type plate 151. A connecting plate 161 connected to the second threaded sleeve 154 is fixedly fitted in the middle of the welding pipe 16. A welding machine 162 is installed on the top of the base 10 on one side of a vertical plate 11. The output port of the welding machine 162 is connected to the welding pipe 16 through a pressure-resistant hose 163.
[0028] As described above, after the spot welding position of the sheet metal steel is located, the motors and welding machine 162 can be started according to the set program. Note that the dual-output reducer 132 is a conventional design, and its detailed working principle will not be elaborated in this article. The first drive motor 133 starts and drives the two first threaded rods 131 to rotate synchronously through the dual-output reducer 132. Then, through the two first threaded sleeves 141, the mounting plate 14 and the components mounted thereon are moved left and right to the designated position. When the designated position is reached, the first drive motor 133 stops, and the second drive motor 155 starts, driving the second threaded rod 153 to rotate. Then, through the second threaded sleeve 154 and the connecting plate 161, the welding pipe 16 is lowered to the welding point. Then, the welding machine 162 starts and heats the welding pipe 16 through the pressure-resistant hose 16 to perform the spot welding process. After one spot welding is completed, the welding machine 162 stops, the second drive motor 155 starts in reverse to reset the welding pipe 16, and the first drive motor 133 continues to start to find the next welding point.
[0029] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
