[0025] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification.

[0026] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this application. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness or purpose of this application, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms such as "front," "back," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this application. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this application.

[0027] It should be noted that in the existing automotive axle housing production, the axle housing processing production line is long, the processing equipment occupies a large space, and the workpiece loading and unloading and processing cannot be carried out on the same line. Usually, it is necessary to use a robot to grab the workpiece on the production line and move it to the processing station on the other side of the production line for processing, or to use a flipping device to flip the workpiece to the processing station for processing. Moreover, the workpiece loading and unloading require separate transfer equipment, which not only has a complex structure and occupies a large space, resulting in a huge production line, but also has low production efficiency due to the waiting time required for workpiece transfer or transportation.

[0028] Please see Figures 1 to 3 This application exemplarily provides an apparatus for processing bridge housings, comprising:

[0029] Base 1;

[0030] A conveying mechanism is located in the middle of the base 1. The conveying mechanism includes at least a slide table 2 and a slide block 3. The slide table 2 is used to carry the workpiece 8. The slide block 3 is located in the middle of the base 1 along the width direction. The slide table 2 can move on the slide block 3. The slide block 3 is provided with a conveying channel, which includes an infeed section, a processing section and an outfeed section. The workpiece 8 enters the conveying channel from the infeed section, passes through the processing section and is sent out by the outfeed section.

[0031] Welding mechanisms are located on both sides of the processing section and are used to process workpiece 8;

[0032] Conveyor line 7 is located at the end of the output section and is used to transport 8 processed workpieces.

[0033] In the bridge housing processing device provided in this application, the workpiece 8 is conveyed by the cooperation of the slide table 2 and slide block 3 of the conveying mechanism. The conveying channel on the slide block 3 is divided into an infeed section, a processing section and an outfeed section. Welding mechanisms are set on both sides of the processing section to process the workpiece 8. The workpiece 8 enters the conveying channel from the infeed section. After being processed by the welding mechanism in the processing section, the processed workpiece 8 is sent out from the outfeed section to the conveyor line 7 for conveying. The workpiece 8 enters the conveying channel, which realizes the production operation of workpiece 8 infeeding, processing and outfeeding. The conveying channel is set in the middle of the base 1 and the welding mechanisms are symmetrically set on both sides of the conveying channel. The structure is more compact, which can shorten the production line and help improve production efficiency.

[0034] In some embodiments, the slide 3 is provided with a guide rail 22 and a drive member 29. The guide rail 22 forms a conveying channel, the slide 2 is mounted on the guide rail 22, and the drive member 29 is used to drive the slide 2 to move on the guide rail 22. Specifically, by moving the slide 2 on the guide rail 22, the feeding, processing and unloading of the workpiece 8 can be controlled. The drive member 29 can be a motor, cylinder or other element that can provide driving force, and this is not limited here.

[0035] In the above embodiment, the slide table 2 is provided with a first station 14 for placing the workpiece 8 to be processed. The first station 14 is provided with a support base 17, a first cylinder 16, a connecting plate 18, and a first bracket 25. The support bases 17 are positioned opposite each other on the first station 14. The first cylinders 16 are respectively mounted on the support bases 17. The connecting plate 18 is positioned between the support bases 17, with both ends of the connecting plate 18 connected to the first cylinders 16. The first bracket 25 is positioned opposite each other on the connecting plate 18. 25 is used to support the workpiece 8. The first cylinder 16 can lift the connecting plate 18 on the support seat 17 to lift the first support 25 and the workpiece 8. Specifically, when the workpiece 8 is fed in, the slide table 2 moves to the feeding section on the slide seat 3 and places the workpiece 8 on the first support 25. The first cylinder 16 drives the connecting plate 18 to lift on the support seat 17 to lift the workpiece 8 on the first support 25. At the same time, the slide table 2 moves to the processing section on the slide seat 3 to lift the workpiece 8 so that it can be processed.

[0036] In this embodiment, a centering assembly is provided on the connecting plate 18. The centering assembly includes a centering block 30 and a third cylinder 32. The centering blocks 30 are arranged opposite each other on both sides of the third cylinder 32. The centering blocks 30 have an arc-shaped centering surface 31. When the workpiece 8 is placed in the first station 14, the third cylinder 32 drives the centering blocks 30 to move away from each other. The centering surface 31 of the centering blocks 30 is in contact with the inner wall of the workpiece 8 to center the workpiece 8. Specifically, the workpiece 8 has a through hole 28. When the workpiece 8 is placed in the first station 14, the through hole 28 of the workpiece 8 passes through the two centering blocks 30. The third cylinder 32 drives the centering blocks 30 to move away from each other. The centering surface 31 of the centering blocks 30 is in contact with the hole wall of the through hole 28 to center the workpiece 8. The centering of the workpiece 8 can be completed when the workpiece 8 is placed, without the need to set up a separate centering mechanism and a transfer mechanism, thus improving production efficiency.

[0037] In this embodiment, the slide table 2 is also provided with a second station 15 for placing the processed workpiece 8. The second station 15 and the first station 14 are arranged opposite to each other on the slide table 2 along the length direction of the guide rail 22. The second station 15 is provided with a second cylinder 19 and a second support 20. The second cylinder 19 is arranged opposite to the second station 15. The second support 20 is connected to the second cylinder 19. The second support 20 is used to support the workpiece 8. The second cylinder 19 can lift the second support 20. Specifically, after the workpiece 8 is processed, the second station 15 places the workpiece 8 to send the workpiece 8 into the conveyor line 7. The second station 15 is closer to the conveyor line 7 than the first station 14.

[0038] In detail, both the first support 25 and the second support 20 are configured as U-shaped structures. The U-shaped structure has an arc-shaped support part 21 on the side near the workpiece 8. The support part 21 supports the workpiece 8 from both sides. The U-shaped support structure can ensure that the workpiece 8 can be stably supported on the first station 14 and the second station 15, and ensure that the workpiece 8 will not fall off during the movement of the slide table 2.

[0039] In some embodiments, the bridge housing processing device further includes a clamping mechanism, which includes a displacement slide rail 9, a displacement slide table 10, and a clamping block 11. The displacement slide rail 9 is disposed opposite to each other on both sides of the processing section. The displacement slide tables 10 are respectively clamped on the displacement slide rail 9 on both sides, and the two displacement slide tables 10 can maintain synchronous movement on the displacement slide rail 9. The clamping block 11 is respectively disposed on the two displacement slide tables 10, and the clamping block 11 has a clamping part 12 on the side facing the workpiece 8. A fourth cylinder 13 is provided on both sides of the displacement slide rail 9. When the workpiece 8 on the first station 14 moves to the processing section, the fourth cylinder 13 drives the two displacement slide tables 10 to move synchronously on the displacement slide rail 9. The workpieces are brought closer together on rail 9, and the clamping parts 12 are brought closer to both ends of the workpiece 8 to clamp it. Specifically, in the initial state, the first station 14 is located in the feeding section, and the second station 15 is located in the processing section. First, the workpiece 8 to be processed is placed on the first station 14. The first cylinder 16 drives the connecting plate 18 to lift the first bracket 25 and the workpiece 8. The centering assembly simultaneously centers the workpiece 8. The slide 2 moves, so that the first station 14 moves from the feeding section to the processing section, and the second station 15 moves from the processing section to the output section. The fourth cylinder 13 drives the displacement slide 10 to move closer together, and the clamping parts 12 of the clamping block 11 move closer to both ends of the workpiece 8 to clamp it. To prevent workpiece 8 from shifting during processing and affecting processing quality, the welding mechanism includes a robotic arm 4 and a welding gun 5. The robotic arm 4 drives the welding gun 5 to process workpiece 8. After processing, the first cylinder 16 retracts the connecting plate 18, and the first support 25 descends. At this time, the clamping block 11 clamps the workpiece 8, and the slide 2 resets and moves, causing the first workpiece 8 to move from the processing section to the feeding section. The second station 15 moves from the output section to the processing section. The first station 14 repeats the operation to place the workpiece 8 to be processed. At the same time, the second support 20 is raised by the second cylinder 19 to receive the processed workpiece 8. The fourth cylinder 13 drives the displacement slide 10 to move away from each other. The clamping part 12 of the clamping block 11 is moved away from both ends of the workpiece 8 and the workpiece 8 is released. The slide table 2 continues to move repeatedly, so that the first station 14 enters the processing section from the feeding section and the second station 15 enters the output section from the processing section. The output section is connected to the conveyor line 7. At this time, the processing operation of the workpiece 8 on the first station 14 and the output operation of the processed workpiece 8 on the second station 15 are carried out simultaneously. The processed workpiece 8 is transported by the conveyor line 7 for output, realizing the synchronous operation of the feeding, output and processing of the workpiece 8. The positioning, clamping, feeding and output operations do not require the processing station to wait. The welding mechanism can perform welding continuously, effectively improving production efficiency.

[0040] In the above embodiment, the clamping part 12 is configured as a semi-circular structure, and the two ends of the workpiece 8 have assembly holes 27. The semi-circular structure matches the assembly holes 27. Specifically, when the clamping block 11 is close to the two ends of the workpiece 8, the semi-circular structure extends into the assembly holes 27 to clamp the workpiece 8.

[0041] In this embodiment, the slide block 3 is provided with a limiting mechanism on the output section, and the bottom of the slide table 2 is provided with a boss structure 26. When the slide block 3 moves to the end of the output section, the boss structure 26 comes into contact with the limiting mechanism to block the movement of the slide block 3. Specifically, the limiting mechanism includes a limiting member 23 and an elastic member 24. There are two boss structures 26, which correspond to the limiting member 23 and the elastic member 24 respectively. The length of the elastic member 24 is greater than the length of the limiting member 23. When the slide table 2 moves to the end of the output section, the boss structure 26 first comes into contact with the elastic member 24. The elastic member 24 provides a buffer for the slide table 2 to prevent the workpiece 8 from falling due to vibration. Then, the limiting member 23 limits the movement distance of the slide table 2 to prevent the slide table 2 from colliding with the conveyor line 7.

[0042] In this embodiment, the bridge housing processing device also includes a cleaning gun mechanism 6 for cleaning the welding mechanism. The cleaning gun mechanism 6 is arranged opposite to each other on both sides of the conveyor line 7. Specifically, the welding mechanism includes a robot arm 4 and a welding gun 5. The cleaning gun mechanism 6 cleans the welding gun 5 to ensure that the welding gun 5 can be processed normally.

[0043] In summary, in the bridge housing processing device provided in this application, the workpiece 8 is conveyed by the cooperation of the slide table 2 and slide block 3 of the conveying mechanism. The conveying channel on the slide block 3 is divided into an infeed section, a processing section, and an outfeed section. Welding mechanisms are set on both sides of the processing section to process the workpiece 8. The workpiece 8 enters the conveying channel from the infeed section, and after being processed by the welding mechanism in the processing section, the processed workpiece 8 is sent out from the outfeed section to the conveyor line 7 for conveying. The workpiece 8 enters the conveying channel, thus realizing the production operation of workpiece 8 infeeding, processing, and outfeeding. Moreover, the conveying channel is set in the middle of the base 1, and the welding mechanisms are symmetrically set on both sides of the conveying channel, making the structure more compact, shortening the production line, and helping to improve production efficiency.

[0044] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
