[0035] As Figures 1 to 9As shown, in the embodiment, the clamping tool for welding workpieces comprises a base 10, a plurality of mounting tables 20, panel pressing devices 30, workpiece pressing devices 40 and a control device. The plurality of mounting tables 20 are arranged at intervals along the length direction of the base 10, each mounting table 20 comprises an inclined table plate 21 and a positioning structure 22 arranged on the upper surface of the inclined table plate 21 for positioning a to-be-welded panel 1, and the inclined directions of the inclined table plates 21 of adjacent mounting tables 20 are opposite. Each mounting table 20 is provided with a panel pressing device 30, the panel pressing device 30 comprises a panel pressing member 31 and a first driving structure 32 for driving the panel pressing member 31 to move in a direction perpendicular to the inclined table plate 21, and the surface of the panel pressing member 31 close to the inclined table plate 21 is a pressing surface for pressing the to-be-welded panel 1. Each mounting table 20 is provided with a workpiece pressing device 40, the workpiece pressing device 40 comprises a workpiece pressing member 41 and a second driving structure 42 for driving the workpiece pressing member 41 to move towards and away from the mounting surface of the to-be-welded panel 1, so as to press the workpiece 2 on the to-be-welded panel 1; the first driving structure 32 and the second driving structure 42 are electrically connected to the control device.

[0036] By applying the technical solution of the embodiment, the base 10 of the clamping tool is provided with a plurality of mounting tables 20, each mounting table 20 comprises an inclined table plate 21 and a positioning structure 22 arranged on the upper surface of the inclined table plate 21 for positioning a to-be-welded panel 1. The above structure makes each mounting table 20 utilize a part of the space in the vertical direction, reduces the space occupied by the mounting table 20 in the horizontal direction, thereby shortening the overall length of the base 10 and reducing the space occupied by the entire clamping tool in the horizontal direction. That is, the above structure reduces the demand of the clamping tool for production space and reduces the possibility of the clamping tool being limited by space; in addition, the inclined directions of the inclined table plates 21 of adjacent mounting tables 20 are opposite, so that the welding space between the two adjacent mounting tables 20 is larger, which is convenient for subsequent welding of the welding robot and improves the welding quality and welding efficiency.

[0037] The process of clamping and welding workpieces will be described in detail below:

[0038] Before welding, the to-be-welded panel 1 is placed on the mounting table 20, and the positioning structure 22 is used to ensure the accurate position of the to-be-welded panel 1.

[0039] The control device is started, the first driving structure 32 of the panel pressing device 30 is controlled, the panel pressing member 31 is moved in a direction perpendicular to the inclined table plate 21, and the to-be-welded panel 1 is tightly pressed against the inclined table plate 21 by the pressing surface of the panel pressing member 31.

[0040] The workpiece 2 is placed at a predetermined position of the to-be-welded panel 1.

[0041] The second driving structure 42 of the workpiece pressing device 40 is controlled to work, so that the workpiece pressing member 41 moves towards the mounting surface of the panel 1 to be welded, and the workpiece 2 is pressed on the panel 1 to be welded.

[0042] The operation of welding the workpiece is performed.

[0043] After the welding is completed, the panel pressing device 30 and the workpiece pressing device 40 are loosened, and the welded workpiece is removed.

[0044] It should be noted that in the embodiment, the positioning structure 22 comprises a plurality of positioning blocks arranged at intervals in the circumferential direction. Of course, in other embodiments not shown in the figure, the positioning structure can also be other structural forms.

[0045] As shown in Figure 1 and Figure 3 In the embodiment, the inclination angle of the inclined platform 21 is between 45° and 75°. If the inclination angle of the inclined platform 21 is less than 45°, the length of the entire base 10 is affected, so that the space occupied by the clamping tool in the horizontal direction is relatively large; if the inclination angle of the inclined platform 21 is greater than 75°, that is, the inclination angle of the inclined platform 21 is too large, on the one hand, the panel 1 to be welded placed on the inclined platform 21 is easy to fall off the inclined platform 21, on the other hand, the welding space between the two adjacent inclined platforms 21 is relatively reduced, thereby being not conducive to welding by the welding robot. Therefore, the inclination angle of the inclined platform 21 is within a suitable range, on the one hand, the space occupied by the clamping tool in the horizontal direction is small, on the other hand, the stability of the panel 1 to be welded is ensured, and on the other hand, the welding space between the two adjacent inclined platforms 21 is large.

[0046] As shown in Figure 1 and Figure 3 In the embodiment, the base 10 comprises a mounting frame 11 and two mounting vertical plates 12 arranged opposite to each other on the mounting frame 11 and along the width direction of the base 10, and opposite two side edges of the mounting vertical plate 12 are mounting inclined surfaces for mounting the mounting platform 20, and the two mounting inclined surfaces are close to each other from bottom to top. The above structure can fix two mounting platforms 20 at the same time through the two mounting vertical plates 12 arranged opposite to each other, so that the number of mounting members is reduced, and the assembly efficiency is improved.

[0047] In the embodiment, two oppositely arranged mounting vertical plates 12 constitute a mounting group (only one group is shown in the figure), and the mounting rack 11 has a plurality of mounting groups arranged at intervals along the length direction thereof. The design of the plurality of mounting groups can simultaneously process a plurality of panels to be welded, greatly improving the batch production capacity and efficiency of welding, and being suitable for large-scale production environment such as continuous welding operation on automobile production line. In addition, the design not only can improve the welding speed, but also can ensure the consistency of welding quality, reduce the production cost, and improve the production efficiency.

[0048] As shown in Figures 1 to 4 and Figure 6 In the embodiment, the bottom plate 3 of the panel to be welded 1 is provided with a middle hole 4 and a workpiece mounting position located on the circumferential outer side of the middle hole 4, the middle part of the inclined platform 21 is provided with a first avoiding hole 211 corresponding to the middle hole 4, the positioning structure 22 is arranged on the circumferential outer side of the first avoiding hole 211, the workpiece pressing device 40 is a plurality of, and at least one bottom plate pressing device is included in the plurality of workpiece pressing devices 40. The bottom plate pressing device includes a first driving source 421 arranged on the lower surface of the inclined platform 21, a first telescopic rod which extends outward from the first avoiding hole 211 and is driven by the first driving source 421, a connecting plate 411 connected with the first telescopic rod, and a first abutting piece 412 arranged on the connecting plate 411. The first abutting piece 412 has a first abutting surface for abutting the workpiece 2 to the bottom plate 3 of the panel to be welded 1. The first driving source 421 and the first telescopic rod form a second driving structure 42, and the connecting plate 411 and the first abutting piece 412 form a workpiece pressing piece 41. Specifically, in the embodiment, by arranging the first avoiding hole 211 corresponding to the middle hole 4 of the bottom plate 3 of the panel to be welded 1 in the middle part of the inclined platform 21, the bottom plate pressing device can ingeniously utilize the space of the lower part of the inclined platform 21. The first driving source 421 and the first telescopic rod directly extend outward from the first avoiding hole 211, which not only avoids direct interference with the middle hole, but also fully utilizes the internal space of the mounting rack (inside the first avoiding hole 211). The compact layout mode makes the size of a single mounting rack assembly (an assembly formed by a single mounting rack and the panel pressing device 30 and the workpiece pressing device 40) smaller, so that more mounting rack assemblies can be arranged in a limited space, greatly improving the overall space utilization of the welding tooling.

[0049] As shown in Figures 1 to 4 and Figure 6As shown, in the present embodiment, the bottom plate pressing device further comprises a second driving source 423 arranged on the lower surface of the inclined platform 21 and a second telescopic rod which is retractable along the length direction of the first avoiding hole 211. The first driving source 421 is connected with the driving end of the second telescopic rod. The first driving source 421, the first telescopic rod, the second driving source 423 and the second telescopic rod form a second driving structure 42. By introducing the second driving source 423 and the second telescopic rod, the first abutting piece 412 connected with the first driving source 421 can realize accurate movement between the upper side of the workpiece mounting position and the upper side of the first avoiding hole 211. This structural design allows quick adjustment of the position of the pressing device without changing the overall layout of the welding tool, so that when the to-be-welded panel 1 is placed or removed, the first abutting piece 412 can automatically move to the upper side of the first avoiding hole 211, ensuring the smooth installation and removal of the to-be-welded panel 1, greatly improving the operation convenience, reducing the labor intensity and operation time of the operator.

[0050] As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, in the present embodiment, the workpiece 2 to be welded includes a bottom plate 3 and a side plate 5 surrounding the periphery of the bottom plate 3, and the workpiece pressing device 40 is multiple, at least including a side plate pressing device, the side plate pressing device includes a second abutting piece 413 pivotally arranged on the upper surface of the inclined table 21, and a driving assembly 425 driving the second abutting piece 413 to rotate, the second abutting piece 413 has a second abutting surface abutting the workpiece 2 to the side plate 5 of the workpiece to be welded, the driving assembly 425 forms a second driving structure 42, and the second abutting piece 413 forms a workpiece pressing piece 41. The above structure has at least the following three advantages: first, improving space utilization and structural compatibility: in the present embodiment, the driving source and telescopic rod of the side plate pressing device are arranged outside the first avoiding hole 211, eliminating the potential problem of structural interference. By arranging the side plate pressing device outside the first avoiding hole 211, the rotary pressing method is adopted, which not only ensures that the workpiece 2 can be firmly pressed on the side plate of the workpiece to be welded, but also optimizes the layout of the equipment in limited space, avoids conflicts with other components in the first avoiding hole 211, and improves the structural compatibility and space utilization efficiency of the entire welding tool. Second, enhance the pressing effect and operation flexibility: the second abutting piece 413 of the side plate pressing device has a pivotable feature, which can be flexibly adjusted according to the specific shape and position of the workpiece 2, ensuring that the second abutting surface forms the best pressing contact with the side plate of the workpiece to be welded, improving the pressing effect. The rotary pressing method not only can firmly fix the workpiece 2, but also provides additional operation flexibility, because the rotation of the second abutting piece 413 can adapt to side plates 5 of various angles and directions, realizing individualized and fine control of workpiece 2 pressing, improving the multifunctionality and adaptability of the welding tool. Third, simplify equipment maintenance: the external arrangement of the side plate pressing device reduces the complexity of the internal structure, simplifies the maintenance and inspection work of the equipment, and reduces the equipment maintenance cost.

[0051] As Figure 5 , Figure 7 and Figure 8As shown, in the present embodiment, the positioning structure 22 comprises a support positioning block, the upper surface of the support positioning block is a support surface perpendicular to the inclined table plate 21, the support surface supports the side plate 5 of the to-be-welded panel 1, the driving assembly 425 comprises a third driving source 4251 fixedly arranged on the inclined table plate 21, a third telescopic rod 4252 which can extend and retract in a direction perpendicular to the support surface, a pressure head 4253 fixed to the driving end of the third telescopic rod 4252, the second avoiding hole 414 for avoiding the pressure head 4253 is arranged on the second abutting piece 413, the second avoiding hole 414 is a long hole, and the pressure head 4253 has a pressure surface 4254 for pressing the second abutting piece 413. Specifically, when it is needed to press the workpiece by the second abutting piece 413, the third driving source 4251 drives the third telescopic rod 4252 to retract, the third telescopic rod 4252 drives the pressure head 4253 to move downward, the pressure surface 4254 of the pressure head 4253 exerts a downward force on the second abutting piece 413, so that the second abutting piece 413 rotates and presses the workpiece 2 downward. When it is needed to install or dismount the to-be-welded panel 1, the third driving source 4251 drives the third telescopic rod 4252 to extend, the third telescopic rod 4252 exerts an upward force on the second abutting piece 413, so that the second abutting piece 413 rotates and moves upward away from the workpiece 2. Since the second avoiding hole 414 is a long hole (the extension direction of the long hole is perpendicular to the pivot direction of the second abutting piece 413), when the second abutting piece 413 rotates, the side surface of the pressure head 4253 does not interfere with the second abutting piece 413, so that the second abutting piece 413 can rotate freely. The above structure is simple and can smoothly drive the second abutting piece 413 to rotate upward or downward.

[0052] As Figure 2 , Figure 4 and Figure 5As shown, in the present embodiment, the side plate pressing device further comprises a sliding table 23 arranged on the inclined table plate 21 and movable in a direction perpendicular to the inclined table plate 21, a fourth driving source 426 for driving the sliding table 23 to move, and a fourth telescopic rod, the second abutting piece 413 is pivotally arranged on the sliding table 23, and the driving assembly 425, the fourth driving source 426 and the fourth telescopic rod form a second driving structure 42. The above structure has at least the following five advantages: first, the operation convenience and the workpiece installation efficiency are enhanced. By introducing the sliding table 23 movable in the direction perpendicular to the inclined table plate 21, the fourth driving source 426 and the fourth telescopic rod for driving the sliding table 23, the second abutting piece 413 can quickly move from the position for pressing the workpiece 2 to the avoiding position. This means that when the workpiece 2 is installed or dismounted, only by controlling the fourth driving source 426 and the fourth telescopic rod, the second abutting piece 413 can be automatically moved to the avoiding position, sufficient space is provided for the smooth entry and exit of the workpiece 2, the preparation and dismounting time of the workpiece 2 is greatly shortened, and the production efficiency is improved; second, the fine control and the pressing precision are improved. The combination of the sliding table 23 and the pivotable second abutting piece 413 enables the second abutting piece 413 to be accurately pressed at the pressing position for pressing the workpiece 2, and to be completely avoided from the workpiece 2 installation area at the avoiding position. This fine control capability ensures the position stability and the pressing precision of the workpiece 2 during the welding process, avoids the welding defects caused by improper pressing, and improves the welding quality and the yield; third, the structural interference is reduced and the space layout is optimized. If the combination of the sliding table 23 and the fourth driving source 426 is not adopted, the second abutting piece 413 needs to be rotated by a large amplitude to avoid the workpiece 2, which not only increases the complexity of the structure, but also may cause interference between components. In the present embodiment, the second abutting piece 413 only needs to be rotated by a small amplitude to cooperate with the movement of the sliding table 23 to achieve avoidance. This design not only simplifies the structure and reduces the interference between components, but also further optimizes the space layout of the equipment, so that the tooling can be designed more compactly while maintaining high efficiency, thereby saving valuable production space.

[0053] AsFigure 1 and Figure 2 As shown in FIG. 1, in the embodiment, the first driving structure 32 is a rotary pressing cylinder, and a driving shaft of the rotary pressing cylinder drives the panel pressing member 31 to move and rotate. The above structure can drive the panel pressing member 31 to rotate and move through one component, which simplifies the structure of the driving device and reduces the production cost.

[0054] The application also provides a welding tool for welding workpieces. The welding tool for welding workpieces according to the embodiment of the application comprises a clamping tool and a welding manipulator. The clamping tool is the clamping tool described above. The welding manipulator is arranged on one side of the clamping tool. Since the clamping tool described above has the advantage of reducing the requirement of the clamping tool for production space, the welding tool with the clamping tool also has the above advantage.
