Description

Technical Field

[0001] This utility model relates to the field of welding tooling and fixture technology, and in particular to a multifunctional integrated tooling. Background Technology

[0002] In modern manufacturing, welding is an indispensable key process in the production of metal structural components. For some structural components that are assembled from multiple parts such as plates and steel sections, the traditional production process usually follows a strict process separation model. First, workers on a special assembly platform perform preliminary positioning and spot welding of each part according to the drawing requirements to complete the assembly process.

[0003] After assembly, the entire workpiece needs to be hoisted to the welding area by cranes and other lifting equipment. During the welding process, in order to ensure that all welds can be welded, workers not only need to move frequently, but also, for large workpieces, they must use lifting equipment to flip them multiple times to expose the welds on different sides. This process not only relies heavily on lifting equipment and increases auxiliary work time, but also brings potential safety risks due to the multiple hoisting and flipping, resulting in low overall production efficiency.

[0004] Welding is a process of intense localized heating and cooling, which inevitably generates welding stress and causes structural deformation. In traditional processes, this deformation problem is usually left to be dealt with after welding is completed. After welding, the workpiece needs to be hoisted to the straightening platform again, where workers use mechanical methods, flame heating, etc. to straighten it. This straightening process is not only time-consuming and labor-intensive, greatly increasing labor intensity and production cycle, but the straightening effect also depends on the worker's experience, making it difficult to guarantee the stability and consistency of quality.

[0005] Therefore, this utility model proposes a multifunctional integrated tooling to address the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a multi-functional integrated tooling, which aims to improve the problem of the separation of workpiece assembly, welding and post-weld straightening processes in the prior art, resulting in a cumbersome production process and difficulty in controlling welding deformation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a multi-functional integrated tooling, comprising: a flipping bracket, and an active end chuck, a driven end chuck, a transmission shaft, a reducer, a motor, and a switch disposed on the flipping bracket;

[0008] Both the driving end chuck and the driven end chuck can be rotatably mounted on the flipping bracket for jointly clamping both ends of the workpiece;

[0009] The motor, reducer, and drive shaft are sequentially connected for transmission. The end of the drive shaft is fixedly connected to the drive end chuck to form a power transmission chain that drives the drive end chuck to rotate. The switch is electrically connected to the motor to control its start and stop.

[0010] Preferably, the flipping bracket is further fixedly connected with a width positioning plate and a length positioning plate, and the flipping bracket is also provided with an anti-deformation reference block located within the area defined by the width positioning plate and the length positioning plate.

[0011] Preferably, it further includes a clamping device, which is installed above the flipping bracket and its clamping direction is toward the anti-deformation reference block.

[0012] Preferably, the anti-deformation reference block is a protrusion structure that extends axially along the transmission shaft and has an arc-shaped top surface.

[0013] Preferably, the extension direction of the length positioning plate is perpendicular to the extension direction of the width positioning plate.

[0014] Preferably, the drive shaft is rotatably supported on the tilting bracket by bearings.

[0015] Preferably, the rotation axis of the active end chuck is coaxial with the rotation axis of the driven end chuck.

[0016] Preferably, the active end chuck and the driven end chuck form an integrated linkage structure through the workpiece they hold, so that when the active end chuck rotates, it drives the driven end chuck to rotate synchronously.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem in the prior art that the assembly, welding, and straightening processes of the workpiece need to be transferred between different workstations, resulting in a complex production process, multiple hoisting and positioning, and low production efficiency. It integrates a positioning plate for workpiece positioning, an anti-deformation reference block for applying anti-deformation, a clamping device for clamping the workpiece, and a flipping mechanism for driving the workpiece to flip onto the same tooling body. This achieves the effect of simplifying the production process, reducing the number of workpiece transfers, and significantly improving production efficiency.

[0019] 2. This utility model, by setting an anti-deformation reference block and using a clamping device to press the workpiece onto the reference block before welding, causes the workpiece to undergo elastic deformation in the opposite direction to the welding thermal deformation in advance. This solves the problem in the prior art that welding thermal deformation is difficult to control and that additional correction processes are required after welding, which increases production costs and time. It achieves the effect of controlling and compensating for welding deformation from the source, reducing or even eliminating the post-weld correction process, and ensuring the quality of product forming.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 The present invention provides an embodiment of a multifunctional integrated tooling, including a flipping bracket 407 and a flipping mechanism 4 disposed on the flipping bracket 407. The flipping bracket 407 is used to provide basic installation and support for the entire tooling, and the flipping mechanism 4 is used to clamp the workpiece and drive the workpiece to flip.

[0027] The flipping mechanism 4 includes an active end chuck 402 and a driven end chuck 403. Both the active end chuck 402 and the driven end chuck 403 are rotatably mounted on the flipping bracket 407. The active end chuck 402 and the driven end chuck 403 are arranged opposite to each other to jointly clamp the workpiece from both ends.

[0028] To achieve the flipping function, the power transmission structure of the flipping mechanism 4 includes a motor 405, a reducer 404, and a transmission shaft 401. The output end of the motor 405 is connected to the input end of the reducer 404, and the output end of the reducer 404 is connected to one end of the transmission shaft 401. The other end of the transmission shaft 401 is fixedly connected to the active end chuck 402, thus forming a power transmission path in which the motor 405 drives the active end chuck 402 to rotate through the reducer 404 to reduce speed and increase torque. The flipping mechanism 4 also includes a switch 406, which is electrically connected to the motor 405 and is used to control the start and stop of the motor 405, thereby controlling the flipping action of the entire flipping mechanism 4.

[0029] A width positioning plate 2 and a length positioning plate 3 are fixedly connected to the flipping bracket 407. The extension direction of the width positioning plate 2 is perpendicular to the extension direction of the length positioning plate 3, thus forming a reference angle for two-dimensional planar positioning of the workpiece. The flipping bracket 407 is also provided with an anti-deformation reference block 1, which is located inside the area defined by the width positioning plate 2 and the length positioning plate 3. The structure of the anti-deformation reference block 1 is a protrusion structure that extends axially along the transmission shaft 401 and has an arc surface on the top surface. It is not a plane, but provides a preset non-planar support surface for the workpiece, so that when the workpiece is placed, its edge can be close to the width positioning plate 2 and the length positioning plate 3 to obtain a precise initial position. At the same time, its main body is correspondingly supported on the anti-deformation reference block 1, creating structural conditions for subsequent pressure to generate reverse deformation.

[0030] In order to apply a stable clamping force to the already positioned workpiece and make it stick to the anti-deformation reference block 1 to produce a preset reverse deformation, a clamping device 5 is also included. The clamping device 5 is installed above the flipping bracket 407, and its clamping action is perpendicular to the anti-deformation reference block 1.

[0031] To ensure the smooth rotation of the drive shaft 401 on the tilting bracket 407 and to reduce frictional losses, the drive shaft 401 is rotatably supported on the tilting bracket 407 by bearings.

[0032] In order to ensure the stability of the workpiece's posture and the concentricity of its rotation during the flipping process and to avoid wobbling, the rotation axis of the active end chuck 402 is set coaxially with the rotation axis of the driven end chuck 403.

[0033] The active end chuck 402 and the driven end chuck 403 form an integrated linkage structure through the workpiece they hold, so that when the active end chuck 402 driven by the motor 405 rotates, it can directly drive the driven end chuck 403 to rotate synchronously through the rigid transmission of the workpiece, without the need to set up an independent drive device for the driven end chuck 403.

[0034] Working principle: When performing the operation, first place the lower cover plate of the workpiece on the flipping bracket 407, so that its edges are close to the length positioning plate 3 and the width positioning plate 2 respectively to complete the initial two-dimensional precise positioning. Then place the bent channel steel of the accessory on the lower cover plate, and similarly make it close to the length positioning plate 3 and the width positioning plate 2. Start the clamping device 5 to apply downward pressure, so that the workpiece and the accessory are tightly fitted to eliminate gaps. Then perform positioning welding to initially fix the two.

[0035] After the tack welding is completed, continue to operate the clamping device 5 to apply pressure, press the tack welded workpiece downward as a whole until it is firmly pressed on the anti-deformation reference block 1. Since the anti-deformation reference block 1 has a specific convex shape, the workpiece will produce a pre-set reverse deformation opposite to the expected welding deformation direction under this pressure, so that the workpiece enters the anti-deformation state before formal welding.

[0036] Afterwards, the operation switch 406 starts the motor 405. The power output by the motor 405 is reduced in speed and increased in torque by the reducer 404, and then transmitted to the active end chuck 402 through the transmission shaft 401, driving the active end chuck 402 to rotate. Since the active end chuck 402 and the driven end chuck 403 have firmly clamped both ends of the workpiece, forming an integrated linkage structure, the rotation of the active end chuck 402 will drive the driven end chuck 403 to rotate synchronously through the rigid connection of the workpiece. Through this flipping action, the weld seams on both sides of the workpiece can be flipped one by one to a horizontal position that is easy to operate for high-quality welding.

[0037] After all welding operations are completed, the clamping device 5 is released. The thermal stress generated by the workpiece during the welding process cancels out the pre-applied reverse deformation, allowing the workpiece to return to a flat state after cooling. This integrates the assembly, welding and straightening functions into one, significantly simplifying the production process.
