Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a rotating welding fixture. Background Technology

[0002] Currently, one step in the production of automotive parts is welding one or more parts. Existing technology typically involves fixing the parts in a fixture and then manually welding them. This process of installing and removing parts using fixtures is cumbersome and time-consuming, reducing production efficiency and increasing labor costs. Alternatively, a welding robot can be used to weld the parts fixed to the fixture. However, since the fixture is generally stationary, the welding robot's stroke needs to be increased, leading to a more complex control process, requiring higher control technology, and increasing both time and power consumption, thus raising production costs. Therefore, we propose a rotating welding fixture. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a rotating welding fixture, which, after development, can effectively solve the problems mentioned in the background art.

[0004] The technical solution of this utility model is as follows:

[0005] A rotating welding fixture includes a support leg, a tilting plate, a first welding mechanism, a second welding mechanism, a first driving mechanism, and a second driving mechanism. The tilting plate is placed on the top surface of the support leg, and the first welding mechanism and the second welding mechanism are respectively arranged on the top surface of the tilting plate. The first driving mechanism and the second driving mechanism are respectively connected to the two ends of the tilting plate. The first welding mechanism and the second welding mechanism are identical in structure except for their installation positions. The first driving mechanism and the second driving mechanism are also identical in structure except for their installation positions.

[0006] The first welding mechanism includes a first welding module, a second welding module, and a third welding module. The first welding module includes a first driving device and a first tilting arm, with the moving end of the first driving device connected to the first tilting arm. The second welding module includes a second driving device and a second tilting arm, with the moving end of the second driving device connected to the second tilting arm. The third welding module includes a third driving device and a third tilting arm, with the moving end of the third driving device connected to the third tilting arm.

[0007] Furthermore, the first, second, and third drive devices are identical in structure except for their installation positions. The first drive device includes a housing, a first drive cylinder, a first rack, a gear sleeve, and a rotating shaft. The housing is fixedly mounted on the top surface of the tilting plate by screws. The first drive cylinder is fixedly mounted inside the housing by screws. The push rod end of the first drive cylinder is fixedly connected to the first rack by screws. The first rack is meshed with the gear sleeve. The rotating shaft is welded inside the gear sleeve. Both ends of the rotating shaft extend outside the housing and are fixedly mounted to both ends of the first tilting arm by screws.

[0008] Furthermore, the top surface of the flip plate, located in the middle of the area enclosed by the first welding module, the second welding module, and the third welding module, is fixedly installed with a first support base and a second support base by screw connection.

[0009] Furthermore, a first fixing seat is fixedly installed on the top surface of the flip plate near the first welding module by screwing, and a first positioning post is welded to the top surface of the first fixing seat. A second fixing seat is fixedly installed on the top surface of the flip plate near the second welding module by screwing, and a second positioning post is welded to the top surface of the second fixing seat.

[0010] Furthermore, the first driving mechanism includes a second driving cylinder, a second rack, a gear, and a connecting plate. The second driving cylinder is fixedly installed at the bottom of the support foot by a pad and bolts. The push rod end of the second driving cylinder is fixedly connected to the second rack by screws or snaps. The second rack is meshed with the gear. The output shaft end of the gear is welded to the connecting plate. The other end of the connecting plate is fixedly connected to the flip plate by screws.

[0011] The beneficial effects of this utility model are as follows:

[0012] Compared with the prior art, this utility model, by providing a first driving mechanism and a second driving mechanism, can drive the rotating plate to rotate, thereby driving the first welding mechanism and the second welding mechanism to rotate inward, facilitating welding by the welding robot. This process can effectively shorten the welding stroke of the welding robot, reduce the complexity and technical requirements of the control process, and also reduce the time and power consumption, thereby reducing production costs. In addition, this utility model is a dual-station welding fixture, which can greatly improve production efficiency. Moreover, the first welding module, the second welding module, and the third welding module, driven by the first driving device, the second driving device, and the third driving device, can drive the first rotating arm, the second rotating arm, and the third rotating arm to directly rotate and fix the parts or rotate and reset them. This process is also quite simple for the installation and disassembly of parts, and takes less time, thereby greatly improving production efficiency. At the same time, it also reduces labor costs and reduces labor expenditure. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0020] like Figure 1-5 As shown,

[0021] A rotating welding fixture includes a support leg 1, a tilting plate 2, a first welding mechanism 3, a second welding mechanism 4, a first driving mechanism 5, and a second driving mechanism 6. The tilting plate 2 is placed on the top surface of the support leg 1. The first welding mechanism 3 and the second welding mechanism 4 are respectively disposed on the top surface of the tilting plate 2. The first driving mechanism 5 and the second driving mechanism 6 are respectively connected to both ends of the tilting plate 2. The first welding mechanism 3 and the second welding mechanism 4 are identical in structure except for their installation positions. The first driving mechanism 5 and the second driving mechanism 6 are identical in structure except for their installation positions. The first welding mechanism 3 includes a first welding module 7, a second welding module 8, and a third welding module 9. The first welding module 7 includes a first driving device 10 and a first tilting arm 11, with the moving end of the first driving device 10 connected to the first tilting arm 11. The second welding module 8 includes a second driving device 12 and a second tilting arm 13, with the moving end of the second driving device 12 connected to the second tilting arm 13. The third welding module 9 includes a third driving device 14 and a third tilting arm 15, with the moving end of the third driving device 14 connected to the third tilting arm 15. In this application, depending on the number of different components being welded, the first welding module 7, the second welding module 8, or the third welding module 9 can be used alone, or the first welding module 7 and the second welding module 8 can be used simultaneously, or the first welding module 7 and the third welding module 9 can be used simultaneously, or the second welding module 8 and the third welding module 9 can be used simultaneously, or the first welding module 7, the second welding module 8, and the third welding module 9 can be used simultaneously.

[0022] In a preferred embodiment, the first drive device 10, the second drive device 12, and the third drive device 14 are identical in structure except for their installation positions. The first drive device 10 includes a housing 16, a first drive cylinder, a first rack, a gear sleeve, and a rotating shaft 17 (the first drive cylinder, the first rack, and the gear sleeve are not shown in the diagram). The housing 16 is fixedly mounted on the top surface of the tilting plate 2 by screws. The first drive cylinder is fixedly mounted inside the housing 16 by screws. The push rod end of the first drive cylinder is fixedly connected to the first rack by screws. The first rack is meshed with the gear sleeve. The rotating shaft 17 is welded inside the gear sleeve. Both ends of the rotating shaft 17 extend outside the housing 16 and are fixedly mounted to both ends of the first tilting arm 11 by screws. It can be understood that after the first drive cylinder is activated, it facilitates the up-and-down movement of the first rack, which in turn drives the gear sleeve and the rotating shaft 17 to rotate, and finally drives the first tilting arm 11 to rotate.

[0023] As another preferred embodiment, the first driving device 10 includes a housing 16 and a hollow rotating platform (not shown in the figure). The hollow rotating platform is fixedly installed inside the housing 16, and the motion output end of the hollow rotating platform is fixedly connected to the rotating shaft 17. After the hollow rotating platform is started, it can drive the rotating shaft 17 to rotate, thereby driving the first tilting arm 11 to rotate.

[0024] In a preferred embodiment, a first support base 18 and a second support base 19 are fixedly installed on the top surface of the flip plate 2, located in the middle of the area enclosed by the first welding module 7, the second welding module 8, and the third welding module 9, by means of screws. The provision of the first support base 18 and the second support base 19 facilitates the placement and installation of automotive parts, and provides auxiliary positioning and support.

[0025] In a preferred embodiment, a first fixing seat is screwed onto the top surface of the flip plate 2 near the first welding module 7, and a first positioning post 20 is welded to the top surface of the first fixing seat. Similarly, a second fixing seat is screwed onto the top surface of the flip plate 2 near the second welding module 8, and a second positioning post 21 is welded to the top surface of the second fixing seat. The presence of the first positioning post 20 and the second positioning post 21 facilitates the positioning and installation of accessories, improves installation accuracy, and consequently enhances the subsequent welding accuracy and quality.

[0026] In a preferred embodiment, the first drive mechanism 5 includes a second drive cylinder 22, a second rack 23, a gear 24, and a connecting plate 25. The second drive cylinder 22 is fixedly mounted on the bottom of the support leg 1 by a pad and bolts. The push rod end of the second drive cylinder 22 is fixedly connected to the second rack 23 by screwing or snapping. The second rack 23 is meshed with the gear 24. The output shaft end of the gear 24 is welded to the connecting plate 25, and the other end of the connecting plate 25 is fixedly connected to the tilting plate 2 by screwing. It can be understood that activating the second drive cylinder 22 drives the second rack 23 to move up and down, thereby driving the gear 24 to rotate. Since the output shaft end of the gear 24 is welded to the connecting plate 25, the tilting plate 2 can be tilted. It is worth mentioning that the second drive cylinders 22 on the first drive mechanism 5 and the second drive mechanism 6 need to work synchronously to effectively drive the tilting plate 2 to tilt.

[0027] The working principle of this utility model is as follows: During operation, automotive parts are first installed, which can be supported by the first support base 18 and the second support base 19, and positioned by the first positioning column 20 and the second positioning column 21. After one or more automotive parts are installed, the drive devices of the first welding module 7, the second welding module 8 and the third welding module 9 can be activated to make their respective flipping arms flip, thereby effectively clamping the automotive parts. Then, the second drive cylinders 22 on the first drive mechanism 5 and the second drive mechanism 6 are activated simultaneously to make the gear 24 rotate, thereby driving the flipping plate 2 to rotate, so that the automotive parts can approach the welding robot. This process can effectively shorten the welding stroke of the welding robot and reduce the complexity and technical requirements of the control process.

[0028] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
