Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] Example 1, by Figures 1 to 10 As shown, this utility model embodiment provides a reinforcing rib positioning and clamping device, which includes a base assembly 1, at least two support assemblies 6 slidably engaged with the base assembly 1 and provided with a conveyor belt 13 for conveying workpieces, a first drive assembly 2 for driving the support assemblies 6 to move closer or further apart, a second drive assembly 7 for driving the conveyor belt 13 to circulate, a first positioning assembly 5 engaged with the base assembly 1 for positioning the workpiece to a preset position, a second positioning assembly 4 engaged with the base assembly 1 for clamping the workpiece at the preset position, a clamping assembly 3 engaged with the base assembly 1 for abutting against the workpiece at the preset position, and a detection assembly for detecting the workpiece. Preferably, there are two symmetrically arranged support assemblies 6, first positioning assembly 5, second positioning assembly 4, and clamping assembly 3.

[0038] The two support components 6 are arranged in parallel to move the workpiece in the direction of the first positioning component 5, the second positioning component 4, and the clamping component 3. The detection component is used to detect whether the workpiece has moved to a preset position range. The first positioning component 5 is used to push the workpiece to the preset position. The second positioning component 4 is used to clamp the workpiece by at least two clamping members 17 that can move closer or further apart from each other. The clamping component 3 is used to abut against the workpiece from a direction perpendicular to the pushing direction of the first positioning component 5.

[0039] The working principle of the reinforcing rib positioning and clamping device in this embodiment is as follows: First, before the workpiece is loaded, the width direction of the two support components 6 is adjusted to the workpiece width dimension by the first drive component 2. The clamping component 3 is first adjusted to a suitable height by the lifting component 26. The second drive component 7 drives the conveyor belt 13 to move, thereby moving the workpiece to a preset position range, that is, the position between the two second positioning components 4. When the workpiece reaches the preset position range, the detection component will detect the workpiece. Then, the first telescopic mechanism 14 of the first positioning component 5 pushes the first positioning member 15 to position the workpiece to one side or center it. Then, the second telescopic member of the second positioning component 4 drives the two clamping members 17 to clamp the workpiece, thereby completing the positioning of the workpiece. Finally, after the second positioning component 4 clamps the workpiece, the clamping component 3 presses the workpiece onto the base component 1 from top to bottom, completing the clamping of the workpiece. After the workpiece is positioned and clamped, the automatic welding gun welds the connection position between the reinforcing rib and the workpiece. After welding is completed, the clamping component 3, the second positioning component 4, and the first positioning component 5 are all away from the workpiece. The first drive component 2 drives the conveyor belt 13 to move the next position of the workpiece that needs to be welded to a preset range, or directly send the workpiece out of the device.

[0040] This invention provides a reinforcing rib positioning and clamping device that significantly improves workpiece positioning accuracy and processing efficiency. Through the coordinated action of the conveyor belt 13, the second drive assembly 7, and the detection assembly, the workpiece is automatically transported to a preset position range, triggering the positioning process and eliminating manual adjustment errors. After the first positioning assembly 5 pushes the workpiece along a straight line to complete initial alignment, the diamond-shaped hinge structure of the second positioning assembly 4 drives the clamping assembly 17 to symmetrically clamp the workpiece through a four-corner linkage mechanism, ensuring balanced force and stable center position. The clamping assembly 3 applies pressure from the vertical direction, forming a three-dimensional spatial constraint, effectively suppressing displacement risks during welding. The entire process achieves automated closed-loop control, greatly improving production efficiency.

[0041] Based on the above embodiments, in an optional embodiment of the present invention, such as Figures 1 to 3 As shown, the first drive assembly 2 includes a first drive rod 12 rotatably engaged with the base assembly 1, at least two first moving blocks 11 movably engaged with the first drive rod 12, and a first drive member 10 adapted to drive the first drive rod 12 to rotate. The first drive rod 12 is a screw. The at least two first moving blocks 11 are threadedly engaged with the first drive rod 12 and can move closer or further apart when the first drive member 10 drives the first drive rod 12 to rotate. The first moving blocks 11 are engaged with the support assembly 6 to drive the support assembly 6 to move.

[0042] The first drive assembly 2 employs a screw and moving block cooperation structure, and through the precise control of the first drive component 10, the spacing of the support assembly 6 is synchronously adjusted. This design allows the device to quickly adapt to workpieces of different widths without the need to change fixtures or adjust the mechanical structure.

[0043] Based on the above embodiments, in an optional embodiment of the present invention, such as Figures 1 to 3 As shown, the second drive assembly 7 includes a drive wheel engaged with the conveyor belt 13, a second drive rod 9 engaged with the drive wheel, and a second drive member 8 engaged with the second drive rod 9. The drive wheel is slidably engaged with the second drive rod 9 to move with the support assembly 6. Preferably, the conveyor belt 13 is a chain. The drive wheel is a sprocket.

[0044] Specifically, the sprocket is slidably but non-rotatably engaged with the second drive rod 9. Preferably, the sprocket is rotatably engaged with the first moving block 11.

[0045] The second drive assembly 7, through the meshing of sprockets and chains, ensures that the conveyor belt 13 maintains stable operation as the support assembly 6 moves. The rigid connection characteristic of the chain avoids slippage, a common phenomenon in belt drives, making it particularly suitable for conveying heavy workpieces. Furthermore, the chains on both sides have high synchronization, preventing workpiece deviation.

[0046] Based on the above embodiments, in an optional embodiment of the present invention, such as Figures 4 to 5 As shown, the first positioning component 5 includes a first telescopic mechanism 14 engaged with the base component 1, and a first positioning member 15 engaged with the first telescopic mechanism 14. The first positioning member 15 is provided to abut against a first positioning surface 16 of the workpiece. Preferably, the first positioning component 5 is constructed in a C-shape, enclosing the second positioning component 4 from top to bottom.

[0047] Based on the above embodiments, in an optional embodiment of the present invention, such as Figures 4 to 7As shown, the second positioning assembly includes a base 22 engaged with the base assembly 1, a second telescopic member engaged with the base 22, a first hinge 20 and a second hinge 24 with their first ends coaxially pivotally connected to the base 22, a third hinge 21 with its first end pivotally connected to the second end of the first hinge 20, a fourth hinge 23 with its first end pivotally connected to the second end of the second hinge 24, and at least two clamping members 17 respectively engaged with the first hinge 20 and the second hinge 24. The second ends of the third hinge 21 and the fourth hinge 23 are pivotally connected so that the first hinge 20, the second hinge 24, the third hinge 21, and the fourth hinge 23 are configured as a rhomboid structure with four corners pivotally connected. The second telescopic member engages at the pivot position of the third hinge 21 and the fourth hinge 23, and is configured to extend and retract toward the pivot position of the first hinge 20 and the second hinge 24, thereby enabling the clamping members 17 to move closer to or further away from each other.

[0048] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 4 As shown, the first hinge 20, the second hinge 24, the third hinge 21, and the fourth hinge 23 are all constructed to include at least two hinges arranged in parallel, and at least one connecting member engaged between the at least two hinges. This embodiment is an example. Figure 7 As shown, the number of hinges is 2, and the number of connectors is 1, so that the first hinge 20, the second hinge 24, the third hinge 21, and the fourth hinge 23 are all constructed as H-shaped structures. In other embodiments, the numbers may be set to other quantities.

[0049] Preferably, the detection component is a proximity sensor. The detection component is located on the side of the pivot position of the first hinge 20 and the second hinge 24 facing the workpiece, and is used to detect whether the workpiece has moved to a position where it can be clamped by the clamping member 17.

[0050] The rhomboid hinge structure of the second positioning component achieves symmetrical movement of the clamping member 17 through a four-corner linkage mechanism. This structure eliminates the eccentric force that may be generated by unilateral drive, ensuring that the workpiece centerline always coincides with the device reference line. Furthermore, the rhomboid transmission structure of the second positioning component enables rapid response and precise positioning of the clamping member 17, effectively improving the efficiency and stability of workpiece clamping, ensuring accurate and stable workpiece positioning during welding, thereby improving welding quality.

[0051] Based on the above embodiments, in an optional embodiment of the present invention, such as Figures 9 to 10As shown, the clamping assembly 3 includes a lifting member 26, a pressure seat 27 engaged with the lifting member 26, and a clamping member 28 engaged with the pressure seat 27. The clamping member 28 is provided with a clamping groove 29 for abutting the workpiece. Specifically, the vertical pressing structure of the clamping assembly 3 and the clamping of the second positioning assembly 4 form a three-dimensional positioning system to create spatial constraints. The clamping groove 29 is constructed with a V-shaped structure, thereby further centering and fixing the workpiece.

[0052] Example 2: This application also provides a welding apparatus, which includes a reinforcing rib positioning and clamping device as described in any section of Example 1, and a welding assembly 25. The welding assembly 25 is engaged with the clamping assembly 3 and / or with the base assembly 1. In this embodiment, for example... Figure 1 , Figure 2 and Figure 8 As shown, the welding assembly 25 is directly mounted on the pressure base 27. While clamping the workpiece, the welding assembly 25 moves synchronously to the welding position, which greatly simplifies the structure of the welding assembly 25.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
