[0002] The traditional welding frock design mainly focuses on welding workpiece on the outer surface of box, which simplifies the welding process to some extent, and facilitates the positioning and operation of welding robot. However, when the welding demand turns to the inner surface of the box, the existing frock design is not up to the task. Due to the limited internal space of the box, the welding robot is difficult to directly contact the combined part of the workpiece and the box, which makes it difficult to achieve automatic welding.

[0031] like Figures 1 to 6 As shown, in this embodiment, the clamping fixture for clamping the workpiece onto the housing includes: a base 10, a tilting table 20, a housing positioning structure 30, a first workpiece placement seat 80, a first clamping structure 90, and a control device. The tilting table 20 is rotatably mounted on the base 10 via a tilting drive structure, and the tilting table 20 is provided with a clearance opening 21. The housing positioning structure 30 is disposed on the mounting surface 22 of the tilting table 20 and located circumferentially outside the clearance opening 21, for supporting and positioning the opening of the housing 1. The first workpiece placement seat 80 is disposed on the mounting surface 22 of the tilting table 20, and the first workpiece placement seat 80 has a first abutting structure 81 that can abut against the inner surface of the bottom wall of the housing 1. A first workpiece mounting groove 811 is provided on the upper surface of the abutment structure 81, and a first welding point avoidance hole 812 communicating with the first workpiece mounting groove 811 is provided on the lower surface of the first abutment structure 81. A first clamping structure 90 is provided on the mounting surface 22 of the flipping table 20. The first clamping structure 90 includes a first clamping head 91 and a first driving structure 92 for driving the first clamping head 91 to move vertically. The first clamping head 91 is located above the first abutment structure 81 and opposite to the first workpiece mounting groove 811. The first clamping head 91 has a first clamping surface 911 that clamps the upper surface of the bottom wall of the box 1. The flipping driving structure and the first driving structure 92 are both electrically connected to the control device.

[0032] Applying the technical solution of this embodiment, the clamping fixture that clamps the workpiece onto the box effectively solves the problem of automated welding of the workpiece on the inner surface of the box through its unique design. First, the first clamping head 91 can abut the bottom wall of the box 1 against the first abutting structure 81, thereby ensuring that the workpiece 2 is tightly attached to the lower surface of the bottom wall of the box 1, ensuring the stability of the welding process and the consistency of welding quality, and reducing the generation of welding defects. Second, by setting a flip-up table 20 on the base 10, and setting a clearance opening 21 and a box positioning structure 30 on the flip-up table 20, the position of the box 1 can be flexibly adjusted. On the one hand, it is convenient for the user to place the box 1 on the clamping fixture, and on the other hand, it allows the welding robot to enter the inner side of the box without obstruction. Furthermore, through the first welding point clearance hole 812 on the first abutting structure 81, the welding robot can weld the joint between the inner surface of the box and the workpiece, realizing automated welding, greatly improving welding efficiency, and reducing the dependence on manual welding. Furthermore, by electrically connecting the flipping drive structure and the first drive structure 92 through the control device, the workpiece 2 and the box 1 are automatically positioned and clamped, which further reduces the need for manual operation, reduces labor costs, and improves the automation level of the production line.

[0033] In summary, the clamping fixture provided in this embodiment not only meets the needs of modern automated production lines, improving production efficiency and welding quality, but also, through its flexible flipping and precise clamping design, enables automated welding of workpieces on the inner surface of the box, effectively solving the limitations of traditional welding fixtures when welding inside the box and providing a new solution for precision welding.

[0034] It should be noted that, in this embodiment, the tilting table 20 has an installation position with the mounting surface 22 facing upwards and a welding position with the mounting surface 22 facing downwards. When the tilting table 20 is in the installation position, the housing 1 is inverted and placed on the tilting table 20. The up-down direction mentioned above refers to the up-down direction when the tilting table 20 is in the installation position.

[0035] like Figures 1 to 3 and Figure 5As shown, in this embodiment, there are multiple first workpiece placement seats 80, each including a wide placement seat 80a. The first abutting structure 81 of the wide placement seat 80a extends inward toward the clearance opening 21. Multiple mounting positions 3 are spaced apart along the width direction on the first abutting structure 81, and each mounting position 3 has a first workpiece mounting groove 811. This design can simultaneously fix multiple workpieces 2, improving production efficiency and making it suitable for scenarios requiring batch welding, such as automotive parts production lines. In the automotive manufacturing process, this design can significantly shorten the welding time of workpieces and increase the throughput of the production line. It is particularly suitable for rapidly changing automotive model production lines, flexibly adapting to the welding needs of different automotive parts, and effectively improving the adaptability and flexibility of the production line.

[0036] like Figures 1 to 3 and Figure 5 As shown, in this embodiment, there are multiple first clamping structures 90, at least a portion of which correspond to the wide placement seat 80a. The first clamping head 91 of the first clamping structure 90 corresponding to the wide placement seat 80a includes a connecting rod 912 driven by the output shaft of the first driving structure 92, and multiple first clamping rods 913 disposed on the connecting rod 912 and corresponding to the mounting position 3. The above structure simplifies the structure of the first clamping head 91, providing clamping structures at the corresponding positions that need clamping, and eliminating material at positions that do not need clamping, thus achieving a lightweight design for the first clamping head 91. This reduces costs and simplifies the movement of the first clamping head 91. Furthermore, and more importantly, this design ensures the stability of each workpiece 2 during the welding process, avoiding welding defects caused by uneven force at a single point, making it suitable for applications requiring high-precision welding, such as the manufacture of precision instruments. In precision instrument manufacturing, even minute displacements of the workpiece can lead to welding failure or a decrease in welding quality. The design of multiple first clamping rods 913 can ensure that the workpiece is subjected to uniform force, improve the accuracy and consistency of welding, and meet the requirements of precision instrument manufacturing for high-precision welding.

[0037] like Figure 1 , Figure 2 and Figure 4As shown, in this embodiment, the mounting position 3 includes a long mounting position 3a having multiple first workpiece mounting slots 811 spaced apart along the length of the wide placement seat 80a, and a short mounting position 3b having a single first workpiece mounting slot 811. The multiple first clamping rods 913 include long clamping rods 913a corresponding to the long mounting position 3a and short clamping rods 913b corresponding to the short mounting position 3b. This structure can simultaneously clamp multiple positions on the bottom wall of the housing 1, ensuring that workpieces in the first workpiece mounting slots 811 at multiple different positions can be clamped together against the bottom wall of the housing 1. This ensures subsequent welding quality and reduces the number of first clamping structures 90, thereby lowering costs.

[0038] like Figure 3 As shown, in this embodiment, the connecting rod 912 and the first clamping rod 913 are integrally formed. This integral forming structure improves the strength and durability of the tooling and facilitates processing. Of course, in other embodiments not shown in the figure, the first clamping rod 913 is adjustablely positioned on the connecting rod 912. If the installation position of the workpiece 2 changes, the position of the first clamping rod 913 can be adjusted so that it is always aligned with the first workpiece mounting groove 811.

[0039] like Figure 3 As shown, in this embodiment, the first driving structure 92 is a rotary clamping cylinder. The output end of the rotary clamping cylinder is driven to connect with the connecting rod 912, so that the first clamping head 91 has a ready position above the first abutting structure 81 and a clearance position away from the first abutting structure 81. Specifically, before the user places the box 1 on the box positioning structure 30, the first clamping head 91 rotates to the clearance position under the drive of the first driving structure 92. At this time, the first clamping head 91 is away from the first abutting structure 81. Since the first clamping head 91 is not directly above the first abutting structure 81, when the user places the box 1, the first clamping head 91 does not affect the lowering of the box 1, so that the box 1 can be smoothly placed on the box positioning structure 30. After the housing 1 is placed, the first drive structure 92 rotates the first clamping head 91 back to its position directly above the first abutting structure 81 and moves the first clamping head 91 downwards, so that the bottom wall of the housing 1 and the workpiece 2 are clamped between the first abutting structure 81 and the first clamping head 91. Therefore, the above structure makes it easy for the user to place the housing 1 on the clamping fixture, thereby improving processing efficiency. In addition, since the first drive structure 92 is a rotary clamping cylinder, the first clamping head 91 can be driven to rotate and move by a single component, simplifying the structure of the drive device and reducing production costs.

[0040] like Figure 2As shown, in this embodiment, there are multiple first workpiece placement seats 80, including a long placement seat 80b. A first abutment structure 81 on the long placement seat 80b extends along the edge of the clearance opening 21. The first abutment structure 81 is provided with multiple first workpiece mounting grooves 811 spaced apart along its length. This design can simultaneously clamp multiple workpieces 2 spaced apart along the edge of the clearance opening 21, reducing the number of first workpiece placement seats 80, improving installation efficiency, and lowering costs.

[0041] like Figure 2 and Figure 4 As shown, in this embodiment, in one implementation, the first clamping structure 90 is a plurality of at least the number of first workpiece mounting slots 811 on the long placement seat 80b, and the first clamping head 91 of the first clamping structure 90 corresponding to the long placement seat 80b includes a second clamping rod 914. This design ensures that the workpiece 2 in each first workpiece mounting slot 811 can be effectively clamped, avoiding welding defects caused by the workpiece 2 not being securely fixed during the welding process. It is suitable for applications requiring high-precision fixing, such as the manufacturing of large mechanical equipment.

[0042] like Figure 2 and Figure 4 As shown, in this embodiment, the first driving structure 92 is a rotary clamping cylinder. The output end of the rotary clamping cylinder is drivenly connected to the second clamping rod 914, so that the first clamping head 91 has a ready position above the first abutting structure 81 and a clearance position directly above the first abutting structure 81. Similarly, the above structure makes it easier for the user to place the housing 1 on the clamping fixture, thereby improving processing efficiency. In addition, since the first driving structure 92 is a rotary clamping cylinder, the first clamping head 91 can be driven to rotate and move by a single component, simplifying the structure of the driving device and reducing production costs.

[0043] like Figure 1 As shown, in this embodiment, the turnover table 20 has multiple welding stations, each corresponding to a set of clearance openings 21. Specifically, the multiple welding stations enable the equipment to process multiple boxes 1 simultaneously, making it suitable for production lines with high output demands. This significantly improves equipment utilization and production efficiency, especially when processing box-type products requiring multi-sided welding. It greatly increases production speed and welding quality while reducing workpiece handling and positioning time, further enhancing the automation level of the production line. The multi-station design allows the equipment to operate continuously like an assembly line, with each box at each station being welded independently without affecting the operation of other stations. This not only improves production efficiency but also reduces production costs.

[0044] like Figures 1 to 3As shown, in this embodiment, the clamping fixture for clamping the workpiece onto the housing further includes a second workpiece placement seat 40 and a second driving structure 50. The second workpiece placement seat 40 is movably disposed on the mounting surface 22 of the tilting table 20 in the horizontal direction. The second workpiece placement seat 40 has a second abutment structure 41 that can abut against the inner surface of the side wall of the housing 1. A second workpiece mounting groove 411 is provided on the outer surface of the second abutment structure 41, and a second welding point avoidance hole 412 communicating with the second workpiece mounting groove 411 is provided on the inner surface of the second abutment structure 41. The second driving structure 50 is drivenly connected to the second workpiece placement seat 40, so that the second workpiece placement seat 40 can move between an abutment position abutting against the side wall of the housing 1 and an avoidance position away from the side wall of the housing 1.

[0045] Applying the technical solution of this embodiment, the clamping fixture clamping the workpiece onto the box effectively solves the problem of automated welding of workpieces on the inner surface of the box through its unique design. First, the second abutment structure 41 on the second workpiece placement seat 40 can attach the workpiece 2 to the inner surface of the side wall of the box 1, ensuring the stability of the welding process and the consistency of welding quality, and reducing the generation of welding defects. Second, by setting a flip-up table 20 on the base 10, and setting a clearance opening 21 and a box positioning structure 30 on the flip-up table 20, the position of the box 1 can be flexibly adjusted. On the one hand, it is convenient for the user to place the box 1 on the clamping fixture, and on the other hand, it allows the welding robot to enter the inner side of the box without obstruction. Furthermore, through the second welding point clearance hole 412 on the second abutment structure 41, the welding robot can weld the joint between the inner surface of the box and the workpiece, realizing automated welding, greatly improving welding efficiency, and reducing the dependence on manual welding. Furthermore, by electrically connecting the flipping drive structure and the second drive structure 50 through the control device, the automated positioning and clamping of the workpiece 2 and the box 1 are realized, which further reduces the need for manual operation, reduces labor costs, and improves the automation level of the production line.

[0046] like Figures 1 to 3As shown, in this embodiment, the clamping fixture further includes a second clamping structure 60, which is disposed on the mounting surface 22 of the tilting table 20. The second clamping structure 60 is located outside the second abutment structure 41 and opposite to the second workpiece mounting groove 411. The second clamping structure 60 includes a second clamping head 61 and a third driving structure 62 for driving the second clamping head 61 to move horizontally. The second clamping head 61 has a second clamping surface 611 that clamps the outer surface of the side wall of the housing 1. The third driving structure 62 is electrically connected to the control device. The second clamping structure 60 further enhances the tightness between the workpiece and the housing, making it suitable for welding operations requiring high-precision positioning. Especially when processing irregularly shaped or large-sized workpieces, it can significantly improve welding quality and production efficiency. For example, when processing large industrial containers or precision electronic equipment housings, the addition of the second clamping structure 60 can effectively prevent the workpiece 2 from separating from the housing 1, resulting in poor welding performance.

[0047] In other embodiments not shown in the figures, the second clamping structure 60 is mounted on the tilting table 20 via the second workpiece placement seat 40. This structure minimizes the distance between the location of the second clamping structure 60 and the side wall of the housing 1, thereby reducing the production cost of the second clamping structure 60.

[0048] The attached diagrams are explained in detail below:

[0049] Figure 1 The core components of the clamping fixture are shown, including a base 10, a tilting table 20, a housing positioning structure 30, a first workpiece placement seat 80, a first clamping structure 90, and a second workpiece placement seat 40. The base 10 serves as the foundation of the entire fixture, supporting the tilting table 20. The tilting table 20 is connected to the base 10 via a tilting drive structure (not shown in the figure), allowing it to tilt between the mounting position and the welding position; that is, the mounting surface 22 can face upwards or downwards. The tilting table 20 has a clearance opening 21 for positioning the workpiece and the housing, and for the robot arm to enter during the welding process. The housing positioning structure 30 is located circumferentially outside the clearance opening 21, supporting and positioning the opening of the housing to ensure the stability of the housing during processing.

[0050] The first workpiece placement seat 80 is located on the mounting surface 22 of the tilting table 20, and has a first abutment structure 81 that can abut against the inner surface of the bottom wall of the housing. The upper surface of the first abutment structure 81 is provided with a first workpiece mounting groove 811 for placing the workpiece 2; the lower surface is provided with a first welding point avoidance hole 812 that communicates with the first workpiece mounting groove 811, ensuring that the welding robot can accurately process the welding point, thereby improving welding efficiency and quality.

[0051] The first clamping structure 90 is also disposed on the mounting surface 22 of the tilting table 20, located above the first workpiece placement seat 80. The first clamping structure 90 includes a first clamping head 91 and a first driving structure 92 for driving the first clamping head 91 to move vertically. The first clamping head 91 has a first clamping surface 911 that abuts against the upper surface of the bottom wall of the housing, ensuring that the position of the workpiece is fixed during the welding process. The first driving structure 92 is a rotary clamping cylinder in the figure; however, in other embodiments not shown in the figure, it can also be a hydraulic cylinder.

[0052] Figure 2 and Figure 3 Further details of the first workpiece placement seat 80 are revealed, including a wide placement seat 80a and a long placement seat 80b, and the components of the corresponding first clamping structure 90. The first abutment structure 81 of the wide placement seat 80a extends inward toward the clearance opening 21, and is provided with multiple mounting positions 3 spaced apart along the width direction. Each mounting position has a first workpiece mounting groove 811. The first clamping head 91 of the first clamping structure 90 corresponding to the wide placement seat 80a includes a connecting rod 912 and multiple first clamping rods 913 corresponding to the multiple mounting positions 3. The first clamping rods 913 may include a long clamping rod 913a and a short clamping rod 913b, corresponding to the long mounting position 3a and the short mounting position 3b on the first workpiece placement seat 80, respectively, ensuring that workpieces in different positions can be accurately positioned and securely fixed.

[0053] Figure 4 A long placement seat 80b is shown, on which a first abutment structure 81 extends along the edge of the clearance opening 21 and is provided with a plurality of first workpiece mounting slots 811 arranged at intervals along the length direction. Corresponding to the long placement seat 80b are a plurality of first clamping structures 90, each first clamping structure 90 including a second clamping rod 914, each second clamping rod 914 corresponding to a first workpiece mounting slot 811 to achieve precise fixation of the workpiece. A first drive structure 92 is a rotary clamping cylinder, the output end of which is drivenly connected to the second clamping rod 914, so that the first clamping head 91 can move between a ready position and a clearance position, facilitating the placement and removal of the workpiece.

[0054] Figure 5 and Figure 6The specific structure of the clamping fixture when the tilting table 20 is in the welding position was examined. Specifically, the second workpiece placement seat 40 is also located on the mounting surface 22 of the tilting table 20 and has a second abutment structure 41 that can abut against the housing. The second abutment structure 41 is provided with a second workpiece mounting groove 411 and a second welding point avoidance hole 412 communicating with the second workpiece mounting groove 411. The second clamping structure 60 is located outside the second abutment structure 41 and includes a second clamping head 61 and a third drive structure 62. The second clamping head 61 has a second clamping surface 611 for clamping against the side wall of the housing. The second drive structure 50 is electrically connected to the control device and is used to drive the workpiece on the second workpiece placement seat 40 to move to a predetermined position to ensure that the workpiece fits against the housing.

[0055] Figure 7 This demonstrates the integrated application of clamping and welding fixtures. The clamping fixture's tilting table 20, driven by a control device, can tilt to either the installation or welding position. When the tilting table 20 is in the welding position, the welding robot 120 performs welding operations between the box and the workpiece. Once the box at one station of the clamping fixture is finished, the welding robot 120 can process the box at the next station. After all the boxes on the clamping fixture have been processed, the welding robot 120 adjusts its position to process the boxes on another clamping fixture.

[0056] In summary, the clamping and welding fixtures of this application achieve efficient positioning and welding of the workpiece and the housing through the flipping operation of the tilting table. The design of the first and second clamping structures ensures the stability and accuracy of the workpiece during the welding process, preventing workpiece displacement and improving welding quality. Meanwhile, the multiple configurations of the first workpiece placement seat and the adjustability of the first clamping rod enhance the versatility and flexibility of the fixture, thereby significantly improving production efficiency and product consistency.

[0057] Regarding the parameters and scope of the embodiments, the number and layout of workpiece mounting slots on the first workpiece placement seat 80 and the second workpiece placement seat 40 can be adjusted according to the size and shape of the workpiece to adapt to the positioning requirements of various workpieces. Parameters such as the working pressure, stroke, and response speed of the rotary clamping cylinder need to be optimized according to the material, weight, and welding requirements of the workpiece to ensure workpiece stability and welding accuracy. The size and position of the clearance opening 21 should ensure that the welding robot can access the welding point without obstruction, while not affecting the positioning stability of the housing and the workpiece.

[0058] like Figure 7As shown, this application also provides a welding fixture for welding a workpiece to a box body. An embodiment of the welding fixture according to this application includes a clamping fixture 110 and a welding robot 120. The clamping fixture 110 is the aforementioned clamping fixture for clamping the workpiece to the box body. The tilting table 20 of the clamping fixture 110 has a mounting position with the mounting surface 22 facing upwards and a welding position with the mounting surface 22 facing downwards. When the tilting table 20 of the clamping fixture 110 is in the welding position, the welding robot 120 welds the box body 1 and the workpiece 2. Since the clamping fixture 110 has the advantage of improving welding quality and efficiency, the welding fixture having it also has the aforementioned advantages.
