Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to an integrated punching and welding equipment and a punching and welding method. Background Technology

[0002] In today's rapidly developing automotive industry, the bumper, as a crucial component of the vehicle's front end, not only protects the vehicle and its passengers in collisions but also serves as the mounting base for sensors in intelligent driving assistance systems, particularly radar mounts. With the continuous advancement of autonomous driving technology, the welding quality of the radar mounts on the bumper directly impacts the accuracy and reliability of the entire intelligent system. However, existing automotive bumper radar mount welding technologies have several shortcomings in practical applications, especially in terms of integration and welding precision.

[0003] Currently, the commonly used welding technology involves directly connecting the punch to a motor or other drive to achieve linear motion of the punch and complete the welding work. The limitations of this technology are mainly reflected in the following aspects: First, the equipment has a low degree of integration, resulting in a large overall size, which is not conducive to a compact layout and efficient operation of the production line; second, because the punch is directly connected to the motor, the minute displacements that may occur when the motor starts and stops are difficult to control precisely, leading to low precision in the welding position, which in turn affects the installation quality and stability of the radar bracket; furthermore, the response speed and motion stability of this driving method may not be sufficient to meet the requirements of high-speed continuous welding, thus affecting the consistency of welding quality. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problems of low integration and unstable processing accuracy of punching and welding equipment in the prior art, and to provide an integrated punching and welding equipment and punching and welding method.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention. Example 1

[0025] See Figures 1 to 3 As shown, this embodiment provides an integrated punching and welding equipment, which includes: a support 100; a welding mechanism 200, the welding mechanism 200 including a welding slide 210 and a welding gun 220, the welding slide 210 being slidably connected to the support 100 along a first direction X, and having a support platform 211 on it, the component to be processed being supported on the support platform 211, the welding gun 220 being disposed on the welding slide 210 and facing the support platform 211; a punching mechanism 300, the punching mechanism 300 including: a mounting frame 310, the mounting frame 310 being connected to the support 100 and located above the welding slide 210; and a driving assembly 320, the driving assembly... Component 320 is disposed on the mounting bracket 310 and includes a pusher 323 that moves along the second direction Y; a transmission component 330, which includes a reversing cam 333 and a connecting bracket 334. The reversing cam 333 is disposed on the moving path of the pusher 323 and can abut against the pusher 323 to move along the first direction X. The connecting bracket 334 is connected to the reversing cam 333 and moves up and down synchronously with the reversing cam 333; and a punching component 340, which is connected to the connecting bracket 334 and includes a punch 342 that moves up and down above the support platform 211.

[0026] The integrated punching and welding equipment described in this embodiment connects and assembles the welding mechanism 200 and the punching mechanism 300 via a bracket 100. The welding mechanism 200 serves both as a support and welding unit for the workpiece, while the punching mechanism 300 performs both punching and clamping functions. Furthermore, the punching mechanism 300 can redirect the impact force via a reversing cam 333, thereby improving punching accuracy and response speed. In addition, the high degree of coordination and rational layout between the aforementioned mechanisms also results in a smaller overall size. Compared to conventional punching or welding equipment currently available, this application offers advantages such as high integration, ease of operation, high processing quality, fast response speed, and wide applicability, making it a promising candidate for use in the industry.

[0027] It should be noted that, for ease of description, in this embodiment, the height direction of the integrated punching and welding equipment is defined as the first direction X, the thickness direction of the equipment is defined as the second direction Y, and the width direction of the equipment is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicular to each other in pairs, and the second direction Y and the third direction Z are located in the same plane.

[0028] See Figures 1 to 3 As shown, in this embodiment, the bracket 100 is used to connect the device to an external fixed platform. It includes a first module 110, an adjusting accessory 120, and a frame 130. Both the adjusting accessory 120 and the first module 110 extend along a first direction X and are respectively connected to both sides of the frame 130. The adjusting accessory 120 is connected to the external fixed platform, and the welding slide 210 is slidably connected to the first module 110. Specifically, in this embodiment, the adjusting accessory 120 is preferably a cylinder, and the first module 110 and the adjusting accessory 120 are respectively disposed on opposite sides of the frame 130.

[0029] In this embodiment, the welding mechanism 200 is disposed below the punching mechanism 300, and the component to be processed can be pressed and fixed between the welding mechanism 200 and the punching mechanism 300. Specifically, the welding carriage 210 in this embodiment is an irregularly shaped component, which is used to provide an installation platform for the welding gun 220 and the support platform 211. Further, in this embodiment, the support platform 211 is disposed at the top of the welding carriage 210, and the welding gun 220 is connected inside the welding carriage 210. Both can move up and down along the first direction X via the welding carriage 210. The welding gun 220 in this embodiment includes a welding driver 221, a transducer 222, and a welding head 223. The welding driver 221 is connected to the welding carriage 210, the transducer 222 is disposed between the welding driver 221 and the welding head 223, and the welding head 223 passes through the support platform 211 and contacts the component to be processed.

[0030] In this embodiment, the mounting bracket 310 provides a connection platform for the drive assembly 320, the transmission assembly 330, and the punching assembly 340. It includes a fixed platform 311 and a fixed plate 312, which are perpendicularly connected. The fixed platform 311 extends along a second direction Y and has a second module 3111 extending in the same direction. The pusher 323 is slidably connected to the second module 3111. The fixed plate 312 extends along a first direction X and has a clearance hole 3122 and a third module 3121. The pusher 323 passes through the clearance hole 3122 and abuts against the reversing cam 333. The connecting bracket 334 is slidably connected to the third module 3121. Based on this, the drive assembly 320 can move along the second direction Y toward the transmission assembly 330, and the transmission assembly 330 can drive the punching assembly 340 to operate along the first direction X.

[0031] Specifically, see Figure 4 and Figure 5 As shown, the drive assembly 320 in this embodiment further includes a horizontal driver 321 and a slide 322. The slide 322 is slidably connected to the second module 3111. The horizontal driver 321 and the pusher 323 are respectively connected to the slide 322, and the pusher 323 is connected to the working end of the horizontal driver 321. The pusher 323 includes a wedge-shaped pusher 3231 and a wedge-shaped limiting member 3232. The wedge-shaped limiting member 3232 is disposed above the wedge-shaped pusher 3231 and is fixedly connected to the wedge-shaped pusher 3231. The lower surface of the wedge-shaped pusher 3231 gradually extends downward in the second direction Y toward the direction away from the reversing cam 333. The upper surface of the wedge-shaped limiting member 3232 gradually extends upward in the second direction Y toward the direction away from the reversing cam 333. The lower surface of the wedge-shaped pusher 3231 abuts against the reversing cam 333, and the upper surface of the wedge-shaped limiting member 3232 abuts against the clearance hole 3122 to limit the movement distance of the pusher 323. Based on the above structural configuration, the wedge-shaped pusher 3231 can push and squeeze the reversing cam 333, while the wedge-shaped limiting member 3232 can cooperate with the clearance hole 3122 to limit the movement distance of the pusher 323, thereby avoiding problems such as excessive movement of the pusher 323 affecting processing efficiency or causing poor connection.

[0032] The transmission component 330 in this embodiment includes a slide plate 331 and an assembly frame 332. The slide plate 331 is slidably connected to the third module 3121. The assembly frame 332 is disposed on the top of the slide plate 331. The reversing cam 333 is disposed inside the assembly frame 332. The assembly frame 332 has a guide surface 3321 on the side facing the drive component 320. The pusher 323 can move along the guide surface 3321. The connecting frame 334 is disposed on the slide plate 331 and has a fourth module 3341 along the first direction X to provide a platform for the movement of the punch 342.

[0033] Furthermore, the punching assembly 340 also includes a pre-pressing assembly 341, which includes a sliding member 3411, a pre-pressing plate 3412, and at least one elastic member 3413. The sliding member 3411 is slidably connected to the fourth module 3341, and its bottom is connected to the pre-pressing plate 3412. The pre-pressing plate 3412 is disposed at the bottom of the connecting frame 334. At least one elastic member 3413 is connected between the pre-pressing plate 3412 and the connecting frame 334. The pre-pressing plate 3412 is provided with a punch 342 through hole, and the punch 342 can pass through the punch 342 through hole and contact the component to be processed. When the re-assembly descends, the punch 342 is located inside the pre-pressure assembly 341. The pre-pressure plate 3412 will preferentially contact the workpiece and form a pre-pressure on the workpiece through the elastic element 3413 to improve its processing quality. Then, the punch 342 is driven by the guide cam to continue to move down until it is exposed to the outside of the pre-pressure assembly 341 and contacts the workpiece for subsequent stamping process.

[0034] This embodiment also includes a control system, with the welding mechanism 200 and the punching mechanism 300 respectively connected to the control system. During actual production and processing, operators can use the control system to adjust the above structure in real time, thereby improving the flexibility of the equipment. Parameters can also be preset through the control system, thereby increasing the automation level of the equipment. Example 2

[0035] This embodiment provides an integrated punching and welding method, which uses the aforementioned integrated punching and welding equipment to perform punching and welding processing between a vehicle bumper and a radar bracket 100, and includes:

[0036] Step S1: Place the component to be processed on the support table 211;

[0037] Step S2: Move the punching mechanism 300 downwards until it contacts and presses against the component to be processed;

[0038] Step S3: Drive component 320 pushes transmission component 330 horizontally, and transmits the force to punch component 340 through transmission component 330, so that punch component 340 moves along the first direction X.

[0039] Step S4: Drive the welding mechanism 200 so that the welding gun 220 is close to the component to be processed and then perform welding processing to complete the punching welding process.

[0040] In summary, the integrated punching and welding equipment and method of this invention connects and assembles the welding mechanism 200 and the punching mechanism 300 via a bracket 100. The welding mechanism 200 serves both as a support and welding unit for the workpiece, while the punching mechanism 300 serves both as a punching and clamping unit. Furthermore, the punching mechanism 300 can redirect the impact force via a reversing cam 333, thereby improving punching accuracy and response speed. In addition, the high degree of coordination and rational layout between the aforementioned mechanisms also results in a smaller overall size. Compared to conventional punching or welding equipment currently available, this application offers advantages such as high integration, ease of operation, high processing quality, fast response speed, and wide applicability, making it a promising candidate for use in the industry.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
