Description

Technical Field

[0001] This application relates to the field of welding technology, and in particular to a clamping fixture and welding apparatus. Background Technology

[0002] In related technologies, brackets and fixtures are typically used to assemble and fix workpieces to facilitate welding.

[0003] However, when welding structures that are enclosed on all sides, the supports and fixtures can easily obstruct the welding path of the welding torch, leading to limitations in the welding process and affecting welding efficiency and quality. Furthermore, after welding, the workpiece is difficult to remove from the tooling. Utility Model Content

[0004] Therefore, it is necessary to provide a clamping fixture and welding device to address the issue of how to improve both welding efficiency and welding quality while enhancing the flexibility of workpiece separation.

[0005] On the one hand, this application provides a clamping fixture, including:

[0006] The mounting plate includes a first mounting surface and a second mounting surface disposed opposite to each other.

[0007] A first suction cup assembly and a second suction cup assembly are both disposed on the first mounting surface. The first suction cup assembly and the second suction cup assembly are capable of moving in opposite directions and moving towards each other along a first direction. The suction surface of the first suction cup assembly is disposed opposite to the suction surface of the second suction cup assembly.

[0008] A third suction cup assembly and a fourth suction cup assembly are both disposed on the second mounting surface. The third suction cup assembly and the fourth suction cup assembly are capable of moving in opposite directions and towards each other along a second direction. The adsorption surfaces of the third suction cup assembly and the fourth suction cup assembly are disposed opposite to each other. The second direction intersects the first direction.

[0009] Multiple sets of gripper mechanisms are provided on the second mounting surface and are used to clamp and fix at least one of the first suction cup assembly, the second suction cup assembly, the third suction cup assembly and the fourth suction cup assembly to the workpiece.

[0010] In one embodiment, the clamping fixture includes a guide rod, a first connecting plate, and a first driving assembly. The guide rod is perpendicularly connected to the mounting plate, and the first connecting plate is slidably connected to the guide rod. The first connecting plate is located on the side of the mounting plate facing away from the second mounting surface. The first driving assembly is connected between the first connecting plate and the mounting plate and is used to drive the first connecting plate to slide along the guide rod. The first connecting plate is linked to the first suction cup assembly, the second suction cup assembly, the third suction cup assembly, and the fourth suction cup assembly. When the first connecting plate slides along the guide rod, it causes the first suction cup assembly and the second suction cup assembly to move in opposite directions, and also causes the third suction cup assembly and the fourth suction cup assembly to move in opposite directions.

[0011] In one embodiment, the clamping fixture includes a first link, a second link, a third link, and a fourth link. The first link, the second link, the third link, and the fourth link are all rotatably connected to the first connecting plate and are respectively used to drive the first suction cup assembly, the second suction cup assembly, the third suction cup assembly, and the fourth suction cup assembly to move relative to the mounting plate when the first connecting plate slides along the guide rod.

[0012] In one embodiment, there are multiple guide rods arranged in parallel and all of them are slidably connected to the first connecting plate.

[0013] In one embodiment, the clamping fixture includes a second connecting plate, a fifth suction cup assembly, and a second driving assembly. The second connecting plate is slidably connected to the guide rod and is located on the side of the first connecting plate facing away from the mounting plate. The fifth suction cup assembly is connected to the side of the second connecting plate facing away from the first connecting plate, with its suction surface facing away from the second connecting plate. The second driving assembly is connected between the second connecting plate and the first connecting plate and is used to drive the second connecting plate to slide along the guide rod, so that the fifth suction cup assembly moves along the guide rod with the second connecting plate.

[0014] In one embodiment, the guide rod, the first direction, and the second direction are perpendicular to each other.

[0015] In one embodiment, the first drive assembly includes a telescopic cylinder or a telescopic electric cylinder; and / or, the second drive assembly includes a telescopic cylinder or a telescopic electric cylinder.

[0016] In one embodiment, at least one of the first suction cup assembly, the second suction cup assembly, the third suction cup assembly, the fourth suction cup assembly, and the fifth suction cup assembly is provided with a cooling water channel.

[0017] In one embodiment, the gripper mechanism includes a gripper and a telescopic drive member. The gripper is rotatably connected to the mounting plate. One end of the telescopic drive member is hinged to the mounting plate, and the other end is hinged to the gripper. When the telescopic drive member extends or retracts, it drives the gripper to rotate relative to the mounting plate, so that the gripper clamps and fixes the workpiece or releases the workpiece.

[0018] On the other hand, this application provides a welding apparatus, including the clamping fixture as described above.

[0019] The aforementioned clamping fixture and welding device utilizes a first, second, third, and fourth suction cup assembly to adsorb and fix the corresponding workpieces to be welded, thereby facilitating subsequent welding of the joints between workpieces. Furthermore, the use of multiple sets of gripper mechanisms to hold and fix the workpieces further improves clamping stability and reduces the risk of workpiece detachment. After welding the workpiece, the gripper mechanisms can be released. Since the first and second suction cup assemblies move in opposite directions in the first direction, and the third and fourth suction cup assemblies move in opposite directions in the second direction, after welding, the first and second suction cup assemblies can be moved closer together, and the third suction cup assemblies can be moved closer together. This allows each suction cup assembly to move away from the inner wall of the workpiece, facilitating the removal of the welded workpiece from the clamping fixture. This avoids the difficulty of separating the workpiece from the fixture in related technologies. Furthermore, since the adsorption surfaces of the first suction cup assembly and the second suction cup assembly are opposite to each other, and the adsorption surfaces of the third suction cup assembly and the fourth suction cup assembly are opposite to each other, after the workpiece is fixed using the above-mentioned clamping fixture, each suction cup assembly of the clamping fixture is located within the space enclosed by the workpiece. Therefore, when welding is performed on the outside of the workpiece using the welding torch, the welding torch will not be obstructed by each suction cup assembly, thereby improving welding efficiency and welding quality.

[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0037] Combination Figure 1 As shown, this application provides a welding apparatus 100 suitable for welding boxes 300 or frames with openings. The objects welded by the welding apparatus 100 are not limited herein. For example, in conjunction with... Figure 2 As shown, in some embodiments, the object welded by the welding device 100 can be a box 300 with an opening formed by four side plates and a bottom plate 305. The joint positions between the four side plates and the bottom plate 305, as well as the joint positions between adjacent side plates, can all be welded using the welding device 100 of this application. For ease of description, the four side plates to be welded will be referred to as "first side plate 301", "second side plate 302", "third side plate 303" and "fourth side plate 304" respectively.

[0038] The welding apparatus 100 includes a clamping fixture 10 and a welding torch 20. The clamping fixture 10 is used to clamp and align the workpieces to be welded according to the product requirements, so that the welding torch 20 can be used to weld the gaps between the workpieces, thereby connecting the workpieces together.

[0039] Combination Figure 3 and Figure 4 As shown, the clamping fixture 10 includes a mounting plate 11, a first suction cup assembly 12, a second suction cup assembly 13, a third suction cup assembly 14, a fourth suction cup assembly 15, and multiple sets of gripper mechanisms 16.

[0040] Mounting plate 11 includes a first mounting surface 111 and a second mounting surface 112 arranged opposite to each other. It should be noted that the first mounting plate 11 and the second mounting surface 112, as surfaces for mounting other components, can be flat, stepped, or curved surfaces, as long as they can meet the installation and use requirements of the clamping fixture 10, such as the first suction cup assembly 12, the second suction cup assembly 13, the third suction cup assembly 14, the fourth suction cup assembly 15, and the multiple sets of gripper mechanisms 16.

[0041] The first suction cup assembly 12 and the second suction cup assembly 13 are both disposed on the first mounting surface 111. The first suction cup assembly 12 and the second suction cup assembly 13 can move away from each other and towards each other along the first direction X. The adsorption surface of the first suction cup assembly 12 is disposed away from the adsorption surface of the second suction cup assembly 13.

[0042] The third suction cup assembly 14 and the fourth suction cup assembly 15 are both disposed on the second mounting surface 112. The third suction cup assembly 14 and the fourth suction cup assembly 15 can move in opposite directions and towards each other along the second direction Y. The adsorption surface of the third suction cup assembly 14 and the adsorption surface of the fourth suction cup assembly 15 are set opposite to each other. The second direction Y intersects with the first direction X.

[0043] Multiple gripper mechanisms 16 are provided on the second mounting surface 112 and are used to clamp and fix at least one of the first suction cup assembly 12, the second suction cup assembly 13, the third suction cup assembly 14 and the fourth suction cup assembly 15 adsorbed workpieces.

[0044] In this embodiment, the first suction cup assembly 12, the second suction cup assembly 13, the third suction cup assembly 14, and the fourth suction cup assembly 15 are used to adsorb and fix the corresponding workpieces to be welded, thereby facilitating the subsequent welding of the joints between the workpieces. Furthermore, the use of multiple sets of gripper mechanisms 16 to clamp and fix the workpieces further improves clamping stability and reduces the risk of workpiece detachment. After welding the workpiece, the clamping and fixing of the multiple sets of gripper mechanisms 16 can be released. Since the first suction cup assembly 12 and the second suction cup assembly 13 move in opposite directions in the first direction X, and the third suction cup assembly 14 and the fourth suction cup assembly 15 move in opposite directions in the second direction Y, after welding the workpiece, the first suction cup assembly 12 and the second suction cup assembly 13 can be moved closer to each other, and the third suction cup assembly 14 can be moved closer to each other. This allows each suction cup assembly to move away from the inner wall of the workpiece, facilitating the removal of the welded workpiece from the clamping fixture 10. This avoids the problem of difficult workpiece and fixture demolding separation in related technologies.

[0045] Furthermore, since the adsorption surfaces of the first suction cup assembly 12 and the second suction cup assembly 13 are opposite to each other, and the adsorption surfaces of the third suction cup assembly 14 and the fourth suction cup assembly 15 are opposite to each other, after the workpiece is fixed by the clamping fixture 10, each suction cup assembly of the clamping fixture 10 is located within the space enclosed by the workpiece. Therefore, when welding is performed on the outside of the workpiece by the welding torch 20, the welding torch 20 will not be obstructed by each suction cup assembly, thereby improving welding efficiency and welding quality.

[0046] Combination Figures 1 to 3As shown, the first suction cup assembly 12, the second suction cup assembly 13, the third suction cup assembly 14, and the fourth suction cup assembly 15 are used to adsorb and fix the first side plate 301, the second side plate 302, the third side plate 303, and the fourth side plate 304, respectively. Since the first suction cup assembly 12 and the second suction cup assembly 13 are opposite each other in the first direction X, and the third suction cup assembly 14 and the fourth suction cup assembly 15 are opposite each other in the second direction Y, the first side plate 301, the second side plate 302, the third side plate 303, and the fourth side plate 304 are arranged to form a frame, and the gaps between adjacent side plates are the positions to be welded. After the side plates are clamped and fixed by the clamping mechanism, the welding gun 20 can be used to weld the gaps between the side plates, so that the side plates are connected as one unit.

[0047] It should be noted that when welding is required on a product with a base plate 305, the clamping fixture 10 can be used to adsorb the four side plates and abut against the base plate 305, or a suction cup assembly for adsorbing and positioning the base plate 305 can be set in the clamping fixture 10.

[0048] For example, combining again Figure 3 and Figure 4 As shown, in some embodiments, the clamping operation further includes a fifth suction cup assembly 17. The fifth suction cup assembly 17 may be disposed on the side of the mounting plate 11 facing away from the second mounting surface 112, and the fifth suction cup assembly 17 is located at the opening formed by the other suction cup assemblies on the side away from the mounting plate 11. The fifth suction cup assembly 17 is used to adsorb and position the base plate 305, so that the base plate 305 abuts against the four side plates, so that the four side plates abutting the base plate 305 can be welded using the welding gun 20 to obtain a box structure 300 with a bottom.

[0049] In some embodiments, the first side plate 301 and the second side plate 302 are the same size, and the third side plate 303 and the fourth side plate 304 are the same size, forming a rectangular frame when the four side plates are arranged together. The size of the first side plate 301 is smaller than the size of the third side plate 303, and the number of suction cups in the first suction cup assembly 12 and the second suction cup assembly 13 is less than the number of suction cups in the third suction cup assembly 14 and the fourth suction cup assembly 15. In this way, the third suction cup assembly 14 and the fourth suction cup assembly 15, which have a larger number of suction cups, can be used to adsorb the larger third side plate 303 and the fourth side plate 304, thereby improving the adsorption stability.

[0050] In some embodiments, the number of suction cups in the first suction cup assembly 12 and the second suction cup assembly 13 can be one. The number of suction cups in the third suction cup assembly 14 and the fourth suction cup assembly 15 is three. The number of suction cups in the fifth suction cup assembly 17 is three. The number of suction cups in each suction cup assembly is not limited here. For example, the number of suction cups in the first suction cup assembly 12 can be one to three, and the number of suction cups in the second suction cup assembly 13 can be one to three; the number of suction cups in the first suction cup assembly 12 can be equal to or unequal to the number of suction cups in the second suction cup assembly 13. The number of suction cups in the third suction cup assembly 14 can be two to five, and the number of suction cups in the fourth suction cup assembly 15 can be two to five; the number of suction cups in the third suction cup assembly 14 can be equal to or unequal to the number of suction cups in the fourth suction cup assembly 15. The number of suction cups in the fifth suction cup assembly 17 can be two to six.

[0051] Combination Figures 5 to 7 The clamping fixture 10 includes a guide rod 101, a first connecting plate 102, and a first driving assembly 103. The guide rod 101 is perpendicularly connected to the mounting plate 11, and the first connecting plate 102 is slidably connected to the guide rod 101. The first connecting plate 102 is located on the side of the mounting plate 11 facing away from the second mounting surface 112. The first driving assembly 103 is connected between the first connecting plate 102 and the mounting plate 11, and is used to drive the first connecting plate 102 to slide along the guide rod 101. The first connecting plate 102 is linked to the first suction cup assembly 12, the second suction cup assembly 13, the third suction cup assembly 14, and the fourth suction cup assembly 15. When the first connecting plate 102 slides along the guide rod 101, the first connecting plate 102 drives the first suction cup assembly 12 and the second suction cup assembly 13 to move in opposite directions, and also drives the third suction cup assembly 14 and the fourth suction cup assembly 15 to move in opposite directions.

[0052] In this embodiment, the lifting and lowering movement of the first connecting plate 102 along the guide rod 101 causes the first connecting plate 102 to move relative to the mounting plate 11 in conjunction with each suction cup assembly, so that each suction cup assembly can be separated from the workpiece after welding is completed, thus improving the ease of operation.

[0053] It should be noted that each suction cup assembly can be slidably mounted on the mounting plate 11. For example, the mounting plate 11 is provided with a first guide rail and a second guide rail parallel to the first direction X. The first suction cup assembly 12 is slidably connected to the mounting plate 11 via the first guide rail, and the second suction cup assembly 13 is slidably connected to the mounting plate 11 via the second guide rail. There can be one or more first guide rails. There can be two or more second guide rails. Correspondingly, in some embodiments, the mounting plate 11 is provided with a third guide rail and a fourth guide rail parallel to the second direction Y. The third suction cup assembly 14 is slidably connected to the mounting plate 11 via the third guide rail, and the fourth suction cup assembly 15 is slidably connected to the mounting plate 11 via the fourth guide rail. The number of third and fourth guide rails can be one or more, and is not limited here.

[0054] Combination Figures 6 to 9 As shown, the clamping fixture 10 includes a first connecting rod 104, a second connecting rod 105, a third connecting rod 106, and a fourth connecting rod 107. The first connecting rod 104, the second connecting rod 105, the third connecting rod 106, and the fourth connecting rod 107 are all rotatably connected to the first connecting plate 102, and are respectively used to drive the first suction cup assembly 12, the second suction cup assembly 13, the third suction cup assembly 14, and the fourth suction cup assembly 15 to move relative to the mounting plate 11 when the first connecting plate 102 slides along the guide rod 101.

[0055] In this embodiment, the movement of the first connecting plate 102 along the guide rod 101 causes the first connecting plate 102 to drive the first suction cup assembly 12, the second suction cup assembly 13, the third suction cup assembly 14, and the fourth suction cup assembly 15 to move relative to the mounting plate 11 via the first connecting rod 104, the second connecting rod 105, the third connecting rod 106, and the fourth connecting rod 107. This satisfies the adsorption and positioning of each suction cup assembly on the workpiece at the welding position, improving the welding quality. At the same time, after welding is completed, each suction cup assembly can be easily moved towards the center of the mounting plate 11 to separate each suction cup assembly from the corresponding workpiece, improving the convenience of separating the workpiece from the clamping fixture 10.

[0056] In some embodiments, there are multiple guide rods 101, which are arranged in parallel and all are slidably connected to the first connecting plate 102. In this embodiment, the use of multiple guide rods 101 improves the motion stability of the first connecting plate 102. The number of guide rods 101 can be two or more. For example, in some embodiments, there are four guide rods 101, which are respectively positioned at the four corners of the mounting plate 11, thereby making the movement of the first connecting plate 102 more stable.

[0057] In the embodiment where the clamping fixture 10 includes a fifth suction cup assembly 17, the fifth suction cup assembly 17 can move relative to the mounting plate 11 in a direction parallel to the guide rod 101, thereby facilitating the separation of the fifth suction cup assembly 17 from the base plate 305 after welding is completed.

[0058] Furthermore, combined Figure 6 and Figure 9 As shown, the clamping fixture 10 includes a second connecting plate 108 and a second driving assembly 109. The second connecting plate 108 is slidably connected to the guide rod 101, and is located on the side of the first connecting plate 102 facing away from the mounting plate 11. A fifth suction cup assembly 17 is connected to the side of the second connecting plate 108 facing away from the first connecting plate 102. The suction surface of the fifth suction cup assembly 17 faces away from the second connecting plate 108, and the second driving assembly 109 is connected between the second connecting plate 108 and the first connecting plate 102. The second driving assembly 109 is used to drive the second connecting plate 108 to slide along the guide rod 101, so that the fifth suction cup assembly 17 moves along the guide rod 101 with the second connecting plate 108.

[0059] It should be noted that the guide rod 101, the first direction X, and the second direction Y are perpendicular to each other. In this way, each suction cup assembly can clamp and position the corresponding workpiece according to the cube, thereby meeting the clamping requirements of the box 300 with a cube shape.

[0060] The first drive assembly 103 includes, but is not limited to, a telescopic cylinder or a telescopic electric cylinder. The second drive assembly 109 includes, but is not limited to, a telescopic cylinder or a telescopic electric cylinder. The types of the first drive assembly 103 and the second drive assembly 109 are not limited here, as long as they can meet the driving requirements of the corresponding structural components.

[0061] The number of first drive components 103 can be two or more, thereby increasing the driving force. When there are two or more first drive components 103, they can be arranged evenly to maintain the stability of the first connecting plate 102 moving along the guide rod 101. Correspondingly, the number of second drive components 109 can be two or more, thereby increasing the driving force. When there are two or more second drive components 109, they can be arranged evenly to maintain the stability of the second connecting plate 108 moving along the guide rod 101. In some embodiments, the number of second drive components 109 is one, and it is set at the middle position between the corresponding second connecting plate 108 and mounting plate 11, which is beneficial for the second drive component 109 to smoothly drive the second connecting plate 108 to move relative to the mounting plate 11 along the guide rod 101. The number and arrangement of the first drive components 103 and the second drive components 109 are not limited here.

[0062] In some embodiments, at least one of the first suction cup assembly 12, the second suction cup assembly 13, the third suction cup assembly 14, the fourth suction cup assembly 15, and the fifth suction cup assembly 17 is provided with a cooling water channel (not shown in the figure). In this way, the corresponding suction cup assembly is cooled by the cooling water channel, which helps to reduce the probability of high temperature and safety accidents during continuous operation of the clamping fixture 10.

[0063] It should be noted that the cooling water channels are not limited to those provided in the suction cup assembly. In some embodiments, corresponding cooling water channels may also be configured for the gripper mechanism 16 to reduce the likelihood of high temperatures occurring during continuous operation of the gripper mechanism 16.

[0064] Combination Figure 6 and Figure 7 As shown, the gripper mechanism 16 includes a gripper 161 and a telescopic drive member 162. The gripper 161 is rotatably connected to the mounting plate 11. One end of the telescopic drive member 162 is hinged to the mounting plate 11, and the other end is hinged to the gripper 161. When the telescopic drive member 162 extends or retracts, it drives the gripper 161 to rotate relative to the mounting plate 11, so that the gripper 161 clamps and fixes the workpiece or releases the workpiece.

[0065] The number of gripper mechanisms 16 can be two or three or more, and is not limited here. For example, in some embodiments, the mounting plate 11 is provided with gripper mechanisms 16 at each of the four corners, so that after the corresponding side plates are adsorbed and positioned by the suction cup assemblies, the corresponding side plates are clamped by these gripper mechanisms 16, which improves the stability of the side plates relative to the clamping fixture 10, thereby reducing the probability of the side plates falling off the clamping fixture 10. This is beneficial to improving the stability of the welding torch 20 in welding each side plate and improving the welding quality.

[0066] See again Figure 1 As shown, in some embodiments, the mounting plate 11 has multiple perforated slots 113. These slots 113 are positioned to avoid the suction cup assemblies and are used to allow the welding torch 20 to extend into the welding position between the side plates adhered to by adjacent suction cup assemblies. This allows the welding torch 20 to weld adjacent side plates from the inside of the side plates, further enhancing the weld quality. The perforated slots 113 can be located at the four corners of the mounting plate 11. The shape and location of the perforated slots 113 are not limited here, as long as they meet the requirement of allowing the welding torch 20 to extend into the space enclosed by the side plates and weld the gaps between adjacent side plates.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
