Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a flexible multi-welding-position puppet welding device. Background Technology

[0002] Puppet welding is a type of welding that uses external manual welding to weld parts on a production line where welding channels are blocked and ordinary welding guns cannot be used. Generally, puppet welding involves fixing the welding gun to an auxiliary mechanism, which guides the welding gun to the part to be welded, thereby completing the welding process.

[0003] Currently, commonly used puppet welding equipment typically allows a single welding machine to weld only one weld point. When a workstation has a large number of weld points that need to be welded using puppet welding, it is only possible to achieve multiple weld points by adding additional welding machines or rotating the materials to be welded.

[0004] However, adding multiple welding guns places stringent requirements on the design space, and it is impossible to arrange multiple puppet welding guns for areas with dense welding points, thus limiting the scope of application. The setting of multiple welding guns also increases the manufacturing cost. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, such as poor applicability and high cost due to the continuous welding gun setting, and to provide a flexible multi-welding position puppet welding device.

[0006] The objective of this utility model can be achieved through the following technical solutions: A flexible multi-position puppet welding device includes a fixed base, a series cylinder group, a sliding platform, a position sensor group, and a welding torch mounting base; One end of the series cylinder assembly is fixed on the fixed base, and the other end is slidably mounted on the fixed base.

The position sensor group is set up along the welding point, and the movable end of the series cylinder group is equipped with a positioning sensing structure that senses the position sensor group. The position sensor group is connected to the series cylinder group through a switching circuit.

[0007] Preferably, the tandem cylinder group includes a fixed cylinder, a transition cylinder, and a moving cylinder arranged coaxially; The fixed cylinder is fixed on the fixed base, and both the transition cylinder and the moving cylinder can be moved and fixed on the fixed base; the movable shaft of the fixed cylinder is connected to the cylinder body of the transition cylinder, the movable shaft of the transition cylinder is connected to the movable shaft of the moving cylinder, and the moving cylinder drives the sliding platform.

[0008] Preferably, the fixed base is equipped with a cylinder mounting seat and a cylinder guide seat, the fixed cylinder is fixed on the cylinder mounting seat, the cylinder guide seat is provided with a guide groove, and the lower ends of the transition cylinder and the moving cylinder are respectively provided with guide blocks that cooperate with the guide groove.

[0009] Preferably, the positioning sensing structure is installed at one end of the moving cylinder and is located in the same horizontal plane as the position sensor group.

[0010] Preferably, the sliding platform includes a mounting base plate and a connecting plate; the connecting plate is vertically fixed to one end of the mounting base plate, and the movable end of the tandem cylinder assembly is fixed to the connecting plate; The mounting base is provided with limiting blocks at both ends, and the fixed base is provided with L-shaped limiting seats.

[0016] Compared with the prior art, the present invention has the following advantages: (1) This solution extends the moving distance of the sliding platform by fixing the welding torch on the sliding platform and driving the sliding platform with a telescopic series cylinder group.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0023] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] Example 1 like Figure 1 As shown, this embodiment provides a flexible multi-welding-position puppet welding device, including a fixed base 1, a series cylinder group 2, a sliding platform 3, a position sensor group 4, and a welding torch mounting base 5; One end of the series cylinder group 2 is fixed on the fixed base 1, and the other end can be slidably mounted on the fixed base 1. The movable end of the series cylinder group 2 is connected to the sliding platform 3. The sliding platform 3 can be slidably mounted on the fixed base 1. The welding gun mounting seat 5 is fixed on the sliding platform 3. The welding gun mounting seat 5 is used to mount the welding gun 7. Position sensor group 4 is set up along the welding point. The movable end of the series cylinder group 2 is equipped with a positioning sensing structure 6 that senses the position sensor group 4. The position sensor group 4 is connected to the series cylinder group 2 through a switching circuit.

[0026] The welding torch is fixed to a sliding platform, and a telescopic series of cylinders drives the platform, extending its movement range. This allows for multi-position welding with a single puppet welding torch, effectively reducing costs. Furthermore, the series of cylinders is equipped with a sensing structure, which, along with a position sensor positioned on one side corresponding to the welding point, positions the cylinders by extending and retracting, thereby positioning the welding torch. This enables welding of concentrated points with small spacing, providing accurate and rapid positioning, improving adjustment efficiency and precision.

[0027] In this embodiment, as Figure 2 As shown, the tandem cylinder group 2 includes a fixed cylinder 21, a transition cylinder 22, and a moving cylinder 23 arranged coaxially; The fixed cylinder 21 is fixed on the fixed base 1, and the transition cylinder 22 and the movable cylinder 23 can be moved and fixed on the fixed base 1. The movable shaft of the fixed cylinder 21 is connected to the cylinder body of the transition cylinder 22, and the movable shaft of the transition cylinder 22 is connected to the movable shaft of the movable cylinder 23. The movable cylinder 23 drives the sliding platform 3.

[0028] A fixed cylinder 21 is used to fix the position of one end of the series cylinder group 2. The extension and retraction of the movable shaft of the fixed cylinder 21 can drive the transition cylinder 22 and the moving cylinder 23 to move together, thereby moving the sliding platform to achieve primary adjustment. The extension and retraction of the movable shaft of the transition cylinder 22 or the movable shaft of the moving cylinder 23 can further move the sliding platform. Here, multiple transition cylinders 22 can be used to extend the adjustment distance, but the number should be appropriate; too many will increase the driving force and energy consumption costs. This series cylinder structure is convenient to adjust and responds quickly. The cylinder buffering improves the overall flexibility of the device and makes the operation safer and more stable.

[0029] In this embodiment, as Figure 3 As shown, a cylinder mounting base 11 and a cylinder guide seat 12 are mounted on the fixed base 1. The fixed cylinder 21 is fixed on the cylinder mounting base 11. The cylinder guide seat 12 is provided with a guide groove. The lower ends of the transition cylinder 22 and the moving cylinder 23 are respectively provided with guide blocks that cooperate with the guide groove. The position sensing structure 6 is installed at one end of the moving cylinder 23 and is located in the same horizontal plane as the position sensor group 4. This ensures that each cylinder can move along the preset direction, improves the movement stability, and also... In this embodiment, the position sensor group 4 includes an initial position sensor 41, a first position sensor 42, a second position sensor 43, and a third position sensor 44, which are sequentially distributed along the extension direction of the series cylinder group 2. The position sensor group 4 is a proximity switch, model TL-Q5MC1, and the position sensing structure 6 is a copper sheet.

[0030] The initial position sensor 41, position sensor 42, position sensor 43, and position sensor 44 are designed to effectively sense the copper sheet of the position sensing structure 6, accurately mark the welding point, and control the movement stroke of the cylinder. This ensures the accurate movement position of the welding torch, enabling adjustment of small-interval welding points with high precision. Specifically, the proximity switches can be connected in parallel, each with its own corresponding control switch, which is then connected in series with the switching circuit. When no copper sheet is sensed, a low-level output is generated, the switching circuit is closed, and the cylinder can move. When the contact switch corresponding to the welding point position is closed, and the contact switch senses the copper sheet, a high-level output is generated, the switching circuit is opened, and the cylinder stops moving, thus stopping at the corresponding welding point and achieving position adjustment.

[0031] In this embodiment, as Figure 4 and Figure 5 As shown, the sliding platform 3 includes a mounting base plate 31 and a connecting plate 32; the connecting plate 32 is vertically fixed to one end of the mounting base plate 31, and the movable end of the series cylinder group 2 is fixed on the connecting plate 32. The mounting base 31 has limit blocks 33 at both ends, and the fixed base 1 has an L-shaped limit seat 13. The L-shaped limit seats 13 are symmetrically distributed on both sides of the mounting base 31 and are on the same straight line as the limit blocks 33. The welding gun mounting seat 5 is fixed on the mounting base 31.

[0032] Furthermore, the sliding platform 31 also includes a sliding guide, which includes a guide rail 34 and a sliding block 35. The mounting base 31 is fixed on the sliding block 35, the guide rail 34 is fixed on the fixed base 1 and is parallel to the tandem cylinder group 2, and the sliding block 35 is slidably mounted on the guide rail 34.

[0033] In this embodiment, there are two sliding guide members, which are distributed parallel to each other. By setting guide rails and sliding blocks below the sliding platform, the welding torch structure on the sliding platform can be supported, ensuring the stability of the welding torch structure's movement.

[0034] In this embodiment, a support block 36 is fixed to the lower end of the mounting base plate 31, and the support block 36 is fixed on the sliding block 35.

[0035] Specifically, the working principle of the flexible multi-welding-position puppet welding device is as follows: The fixed base device is connected to the fixed cylinder. Series cylinder connector 1 connects the movable shaft of the fixed cylinder to the cylinder body of series cylinder 1. Series cylinder connector 2 connects the movable shaft of series cylinder 1 to the movable shaft of series cylinder 2. The cylinder body of series cylinder 2 is connected to the sliding platform device. The guide rail of the linear guide device is mounted on the fixed base. The slider is connected to the sliding platform device. The welding torch mounting base is mounted on the sliding platform device. The welding torch is fixed on the welding torch mounting base. The position sensing device is mounted on series cylinder 2. Position sensors 1, 2, 3, and 4 are mounted on the fixed base device. In the initial position, the extension shafts of all three cylinders are in the retracted state, and position sensor 1 has a position signal. When welding position 1 is required, the telescopic shaft of the fixed cylinder extends. After it reaches its position, the position sensor 2 sends a signal, and the welding gun starts welding. When welding position 2 is required, the telescopic shaft of the series cylinder 1 extends. After it reaches its position, the position sensor 3 sends a signal, and the welding gun starts welding. When welding position 3 is required, the telescopic shaft of the series cylinder 2 extends. After it reaches its position, the position sensor 4 sends a signal, and the welding gun starts welding. This achieves the purpose of welding multiple welding points with a single puppet welding gun.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
