[0023] This utility model proposes a welding positioning device and a production system for composite plates, aiming to solve the problem in the prior art that when the base plate has a positional deviation, manual correction is required, resulting in high labor intensity for workers and low production efficiency. Figures 1 to 3 This is a schematic diagram of an embodiment of the welding positioning device for assembled plates proposed in this utility model.

[0024] The welding positioning device 100 for assembled plates proposed in this utility model will be further illustrated below through embodiments. These embodiments are implemented based on the technical solution of this utility model, providing detailed implementation methods and specific operating procedures. However, the scope of protection of this utility model is not limited to the following embodiments.

[0025] Please see Figure 1 and Figure 2 The composite panel includes a base plate 200 and an annular plate 300. The base plate 200 has a circular plate portion 210. The annular plate 300 is located at the outer edge of the top surface of the circular plate portion 210 and includes multiple interlocking arc-shaped plate portions 310 that can form a complete annulus. The welding positioning device 100 for the composite panel proposed in this utility model includes a mounting platform 1, multiple base plate positioning modules 2, and multiple clamping modules 3. The mounting platform 1 is used to place the composite panel in a horizontal direction. The multiple base plate positioning modules 2 are all arranged on the mounting platform 1 and are distributed circumferentially along the circular plate portion 210. The multiple base plate positioning modules 2 can all move radially along the circular plate portion 210 to cooperate with each other to position the center of the circular plate portion 210. The multiple clamping modules 3 are arranged one-to-one with the multiple arc-shaped plate portions 310. The clamping modules 3 are used to apply downward pressure to the arc-shaped plate portions 310 to press the arc-shaped plate portions 310 onto the circular plate portion 210.

[0026] In this application, the vertical direction X is a relative direction. The vertical direction X is actually the relative direction between the base plate 200 and the annular plate 300. It can be adjusted adaptively in specific applications.

[0027] In the technical solution of this application, multiple base plate positioning modules 2 are distributed circumferentially around the circular plate portion 210, and each can move radially along the circular plate portion 210. When the multiple base plate positioning modules 2 move synchronously radially along the circular plate portion 210, they can clamp the circular plate portion 210, thereby positioning the center of the circular plate portion 210 through mutual cooperation. Therefore, when the base plate 200 is installed on the mounting table 1, the welding positioning device 100 can position the circular plate portion 210 of the base plate 200 through the multiple base plate positioning modules 2, thereby indirectly positioning the entire base plate 200, avoiding positional deviation of the base plate 200, thereby reducing the labor intensity of workers and improving production efficiency.

[0028] The welding positioning device 100 also includes multiple clamping modules 3, each corresponding to one of the multiple arc-shaped plate portions 310. Each clamping module 3 can apply downward pressure to the corresponding arc-shaped plate portion 310, thereby pressing each arc-shaped plate portion 310 onto the circular plate portion 210 of the base plate 200. The clamping modules 3 can clamp and fix the arc-shaped plate portions 310 positioned and installed on the base plate 200, preventing accidental shaking of the arc-shaped plate portions 310 and ensuring welding accuracy.

[0029] When multiple base plate positioning modules 2 cooperate to center the circular plate portion 210, the multiple base plate positioning modules 2 will push the base plate 200 to the welding position. However, in practical applications, the base plate 200 is heavy and difficult to push. Therefore, in one embodiment of this application, the welding positioning device 100 also includes multiple support components 4 and multiple rolling components 5. The multiple support components 4 are spaced apart on the mounting platform 1, and the tops of the multiple support components 4 can work together to form a mounting area for placing the assembled plate; the multiple rolling components 5 are correspondingly arranged on the multiple support components 4 and can form rolling contact with the bottom surface of the circular plate portion 210.

[0030] When the base plate 200 is welded, the transport robot places the base plate 200 on top of the mounting area formed by multiple support components 4. Each support component 4 is equipped with a rolling component 5 on its top. When the base plate 200 is placed in the mounting area, it will make rolling contact with the rolling component 5. Through the rolling contact between the base plate 200 and the rolling component 5, the friction between the base plate 200 and the rolling component 5 is greatly reduced, and the multiple base plate positioning modules 2 can push the base plate 200 more smoothly, reducing the working difficulty of the multiple base plate positioning modules 2.

[0031] Specifically, each support component 4 includes a support base 41 and a lifting platform on which a rolling component 5 is mounted. The top of the support base 41 forms an upward-facing mounting groove 411. The lifting platform is movably mounted in the mounting groove 411 along the vertical direction X. When the lifting platform is at a preset height, at least a portion of the rolling component 5 is exposed in the mounting groove 411.

[0032] When multiple base plate positioning modules 2 need to center the base plate 200, multiple lifting platforms will rise synchronously to a preset height, so that each rolling component 5 is at least partially exposed outside the mounting groove 411, and the multiple rolling components 5 will lift the base plate 200 together. At this time, the multiple rolling components 5 replace the multiple bearing seats 41 to support the base plate 200, and each rolling component 5 has rolling contact with the base plate 200, thereby reducing the friction at the bottom of the base plate 200. After the multiple base plate positioning modules 2 complete the positioning of the base plate 200, the multiple lifting platforms move downward synchronously to reset, so that the multiple rolling components 5 move downward synchronously and drive the base plate 200 to move together. When the multiple rolling components 5 return to the mounting groove 411, the base plate 200 re-contacts the top of the bearing seat 41 and is placed on the bearing seat 41, restoring the movement resistance of the base plate 200 and preventing the base plate 200 from shifting again after the positioning is completed.

[0033] In this embodiment, multiple rolling components 5 will raise the base plate 200 when positioning is required. Therefore, the base plate positioning module 2 needs to adaptively adjust the height of the positioning components. The specific adjustment value needs to be set according to the actual situation and is not limited here. In addition, each rolling component 5 includes multiple rolling elements, which jointly contact the base plate 200. There are many ways to set the rolling elements. For example, the rolling elements can be set as balls partially embedded in the lifting platform, or as rollers installed on the lifting platform, etc., as long as the rolling elements can make rolling contact with the base plate 200.

[0034] Specifically, the base plate positioning module 2 includes a first mounting plate 21 and positioning wheels 22. The first mounting plate 21 is disposed on the mounting platform 1 and moves radially along the circular plate portion 210; the positioning wheels 22 are rotatably disposed on the first mounting plate 21, and the positioning wheels 22 of the multiple base plate positioning modules 2 are all used to apply a thrust to the side wall of the circular plate portion 210 so as to cooperate with each other to position the center of the circular plate portion 210.

[0035] When multiple base plate positioning modules 2 need to perform circular positioning of the base plate 200, multiple first mounting plates 21 will move synchronously toward the base plate 200 along the radial direction of the circular plate portion 210, thereby causing multiple positioning wheels 22 to move synchronously toward the base plate 200 along the radial direction of the circular plate portion 210, and apply a pushing force to the side wall of the circular plate portion 210 respectively, pushing the circular plate portion 210 to the preset welding position.

[0036] Multiple base plate positioning modules 2 are distributed circumferentially around the circular plate portion 210, and the positioning wheels 22 in the multiple base plate positioning modules 2 are also distributed circumferentially around the circular plate portion 210. This allows them to position the center of the circular plate portion 210 by pushing against it from different directions. Furthermore, the number of positioning wheels 22 is at least three (e.g., three, four, five, or other numbers). Preferably, in this embodiment, the number of positioning wheels 22 is three, which ensures the positioning effect of the center of the circular plate portion 210 and also helps reduce the number of parts. In addition, the number of positioning wheels 22 mounted on the first mounting plate 21 can be adjusted according to actual needs and the usage environment. For example, multiple positioning wheels 22 can be spaced apart on the first mounting plate 21, and multiple first mounting plates 21 can each be equipped with a different number of positioning wheels 22. The specific arrangement and actual number are not limited here.

[0037] Furthermore, the first mounting plate 21 can move radially along the circular plate portion 210 in many ways. For example, each base plate positioning module 2 can drive the first mounting plate 21 through a linear drive device, and the direction of movement of the output shaft of the linear drive device is radial to the circular plate portion 210. The linear drive device can be configured as a cylinder, hydraulic cylinder, or linear motor, etc. In addition, each first mounting plate 21 can be provided with a slide rail extending radially along the circular plate portion 210, and the mounting platform 1 is provided with a slider corresponding to each slide rail, so that each first mounting plate 21 can be slidably mounted on the mounting platform 1 radially along the circular plate portion 210. The first mounting plate 21 can also be directly connected to the output shaft of the linear drive device. The specific configuration of the first mounting plate 21 can be adjusted according to the actual situation.

[0038] Further, please refer to Figures 1 to 3 The base plate 200 also includes a protrusion 220 formed on the radially outer side of the circular plate portion 210. At least one arcuate plate portion 310 is located on the side where the protrusion 220 is located. The plurality of clamping modules 3 include a first clamping module 3a corresponding to the arcuate plate portion 310 on the side where the protrusion 220 is located. The welding positioning device 100 also includes a second mounting plate 101. The second mounting plate 101 is disposed on the mounting table 1 and is used to press the protrusion 220 downward. The second mounting plate 101 is movable along the protrusion direction of the protrusion 220. The first clamping module 3a is disposed on the second mounting plate 101.

[0039] In the practical application of this application, the base plate 200 is not perfectly circular, but is composed of a circular plate portion 210 and a protrusion portion 220. However, the connection between the circular plate portion 210 and the protrusion portion 220 may require welding an arc-shaped plate portion 310. Therefore, a corresponding clamping module 3, namely the first clamping module 3a in this embodiment, needs to be installed at the connection between the circular plate portion 210 and the protrusion portion 220. However, the protrusion portion 220 may affect the normal operation of the first clamping module 3a. Therefore, the welding positioning device 100 provides a second mounting plate 101 for the arc-shaped plate portion 310 at the connection between the circular plate portion 210 and the protrusion portion 220. The second mounting plate 101 can be positioned above the protrusion portion 220 to avoid the protrusion portion 220. In addition, the second mounting plate 101 can move along the protruding direction of the protrusion portion 220, thereby driving the first clamping module 3a on the second mounting plate 101 to move closer to or away from the arc-shaped plate portion 310, so that the first clamping module 3a can clamp the arc-shaped plate portion 310.

[0040] Specifically, the installation method of the second mounting plate 101 can be similar to that of the first mounting plate 21. For example, the second mounting plate 101 can be driven by a linear drive device, and the direction of movement of the output shaft of the linear drive device is the protrusion direction of the protrusion 220. The linear drive device can be configured as a cylinder, hydraulic cylinder, or linear motor, etc. In addition, a slide rail extending along the protrusion direction of the protrusion 220 can be provided on the second mounting plate 101, and a slider is provided on the mounting platform 1 corresponding to the slide rail, so that the second mounting plate 101 can be slidably mounted on the mounting platform 1 along the protrusion direction of the protrusion 220. The second mounting plate 101 can also be directly connected to the output shaft of the linear drive device. The specific configuration of the second mounting plate 101 can be adjusted according to the actual situation.

[0041] Specifically, the plurality of clamping modules 3 also include a second clamping module 3b which is circumferentially offset from the arcuate plate portion 310 on the side where the protrusion 220 is located. The second clamping module 3b is disposed on the first mounting plate 21. Both the first clamping module 3a and the second clamping module 3b include a telescopic member 31 and a pressing member 32. The telescopic member 31 of the first clamping module 3a is telescopically disposed on the second mounting plate 101 in the vertical direction X. The telescopic member 31 of the second clamping module 3b is telescopically disposed on the first mounting plate 21 in the vertical direction X. The pressing member 32 is disposed at the telescopic end of the telescopic member 31 and is used to apply downward pressure to the arcuate plate portion 310.

[0042] In this embodiment, when the arc-shaped plate portion 310 needs to be pressed and fixed onto the circular plate portion 210, the telescopic member 31 retracts downward, thereby driving the pressing member 32 closer to the arc-shaped plate portion 310. When the telescopic member 31 retracts downward to a certain extent, the pressing member 32 located at the telescopic end of the telescopic member 31 presses against the arc-shaped plate portion 310. When the arc-shaped plate portion 310 does not need to be pressed, the telescopic member 31 returns to its original position and extends outward, thereby driving the pressing member 32 away from the arc-shaped plate portion 310. Specifically, the telescopic member 31 can actually be directly set as the output shaft of a linear drive device, such as the telescopic shaft of a servo cylinder or the output shaft of a linear motor, while the specific structure of the pressing member 32 is more flexible and can be adapted according to the shape and size of the arc-shaped plate portion 310, and is not limited here.

[0043] After the welding positioning device 100 completes the positioning of the base plate 200 and the clamping of the arc-shaped plate portion 310, the welding robot will begin welding. The welding positions generally include the arc-shaped contact gap between each arc-shaped plate portion 310 and the base plate 200, and the connection between two adjacent arc-shaped plate portions 310. When the welding robot welds the arc-shaped contact gap between the arc-shaped plate portion 310 and the base plate 200, the welding torch will move along the extension direction of the arc-shaped plate portion 310. At this time, the pressing member 32 may interfere with and hinder the movement of the welding robot. Therefore, further, the telescopic member 31 of the first clamping module 3a is rotatably mounted on the second mounting plate 101, and the telescopic member 31 of the second clamping module 3b is rotatably mounted on the first mounting plate 21. When the welding robot approaches the pressing member 32, the telescopic member 31 corresponding to the pressing member 32 will rotate and drive the pressing member 32 to move together, thereby allowing the pressing member 32 to avoid the welding robot and ensuring the normal operation of the welding robot.

[0044] Furthermore, the number of arc-shaped plate portions 310 is not limited, but the fewer the number of arc-shaped plate portions 310, the larger the volume of each arc-shaped plate portion 310. When the volume of the arc-shaped plate portion 310 is large, a single pressing member 32 may be insufficient to press the arc-shaped plate portion 310 firmly. Therefore, in one embodiment of this application, a plurality of second pressing modules 3b are provided on the first mounting plate 21, and the plurality of second pressing modules 3b are distributed at intervals on the first mounting plate 21 along the extension direction of the corresponding arc-shaped plate portion 310.

[0045] The first mounting plate 21 is provided with a plurality of second clamping modules 3b, and the plurality of second clamping modules 3b are distributed at intervals on the first mounting plate 21 along the extension direction of the corresponding arc-shaped plate portion 310. The plurality of second clamping modules 3b can clamp different parts of the arc-shaped plate portion 310 mounted on the first mounting plate 21 respectively, thereby improving the clamping effect on the corresponding arc-shaped plate portion 310 of the first mounting plate 21.

[0046] In another embodiment of this application, the second mounting plate 101 is provided with a plurality of first clamping modules 3a, which are spaced apart on the second mounting plate 101 along the extension direction of the corresponding arc-shaped plate portion 310. The plurality of first clamping modules 3a can clamp different parts of the arc-shaped plate portion 310 mounted on the second mounting plate 101 respectively, thereby improving the clamping effect on the corresponding arc-shaped plate portion 310 of the second mounting plate 101. Of course, different numbers of first clamping modules 3a can be provided on the first mounting plate 21 and the second mounting plate 101, or multiple first clamping modules 3a can be provided simultaneously. The specific number of first clamping modules 3a can be selected and adjusted according to actual needs.

[0047] Please see Figures 1 to 3After the welding positioning device 100 completes the positioning, when the welding robot performs welding, it needs to weld step by step around the extension direction of the annular plate 300. This requires the welding robot to perform relatively complex movements, which places high demands on the control of the welding robot. Therefore, in some embodiments, the welding positioning device 100 also includes a base 102, and the mounting platform 1 is rotatably mounted on the base 102 about the axis in the vertical direction X.

[0048] After the welding robot completes the welding between the curved plate 310 and the base plate 200, the mounting table 1 rotates relative to the base 102 and the welding robot by a preset angle. Then, the welding robot only needs to reset and repeat the previous welding action to complete the welding again. In this way, the welding robot can easily complete the welding of the assembled plates. The welding positioning device 100 replaces the complex activities of the welding robot by rotating the mounting table 1, simplifying the production process and reducing the production difficulty.

[0049] This application also proposes a modular panel production system, which includes the welding positioning device 100 as described above. Any modular panel production system that includes the welding positioning device 100 of any of the above embodiments falls under the category of modular panel production systems described in this application. Furthermore, the modular panel production system also includes components such as a base plate transport device, an arc-shaped plate transport device, and a welding robot. The modular panel production system, with the welding positioning device 100, can accurately weld the base plate 200 to the circular mounting plate 300, efficiently producing the required pump truck turntable base plates.

[0050] The preferred embodiments of this utility model have been described in detail above; however, this utility model is not limited thereto. Within the scope of the technical concept of this utility model, various simple modifications can be made to the technical solution of this utility model, including combining the various technical features in any other suitable manner. These simple modifications and combinations should also be considered as the content disclosed by this utility model and are all within the protection scope of this utility model.
