Description

Technical Field

[0001] This utility model relates to the field of robotic arm base technology, and in particular to a robotic arm base for automotive welding parts. Background Technology

[0002] In the modern automotive manufacturing industry, welding is a crucial step in the assembly of automotive parts. With the booming development of the automotive industry and the ever-increasing demands for automotive quality and production efficiency, automated welding technology has been widely applied, with welding robotic arms playing a central role. Existing robotic arm bases for automotive welding parts generally use bolts to connect the robotic arm to the base. This bolt-fixing method is not only extremely cumbersome, requiring specialized tools to tighten multiple bolts individually, consuming significant time and labor costs, but also, especially on large-scale automotive production lines, the frequent installation and debugging of robotic arms, due to the time-consuming bolt fixing, severely slows down the overall production pace. Furthermore, after long-term use, the bolts are prone to loosening due to mechanical vibration and thermal stress generated during welding operations. Once the bolts loosen, the positional stability of the welding robotic arm will be greatly reduced, leading to a sharp decline in welding accuracy and resulting in weld deviations and weak welds. Therefore, this utility model proposes a robotic arm base for automotive welding parts. Utility Model Content

[0003] The purpose of this utility model is to address the issue that in the background technology, the robotic arm base for automotive welding parts is generally connected to the base by bolts. This bolt-fixing method is not only extremely cumbersome to install, requiring the use of special tools to tighten multiple bolts one by one, which consumes a lot of time and manpower, but also, especially on large-scale automotive production lines, the frequent installation and debugging of robotic arms, due to the time-consuming bolt fixing, seriously slows down the overall production rhythm. Moreover, after long-term use, the bolts are prone to loosening due to mechanical vibration, thermal stress generated by welding operations, and other factors. Once the bolts loosen, the positional stability of the welding robotic arm will be greatly reduced, resulting in a sharp decline in welding accuracy and causing problems such as weld deviation and weak welding in the welded products. Therefore, this invention proposes a robotic arm base for automotive welding parts.

[0006] Optionally, the limiting component includes a limiting ring that is movably sleeved on the outer wall of the base. The upper surface of the limiting ring is provided with a first limiting groove, and a plurality of springs are fixedly provided on the bottom surface of the limiting ring. One end of each spring is fixedly connected to the base plate.

[0007] Optionally, a set of annular guide rails is fixedly installed inside the base. Annular guide grooves are formed on the opposite surfaces of the annular guide rails.

[0028] Example

[0029] like Figure 1 and Figure 2 As shown, the present invention proposes a robotic arm base for automotive welding parts, comprising: a welding robotic arm 1 for welding, capable of welding automobiles; a mounting base 2 fixedly disposed at the bottom of the welding robotic arm 1, with a slot 3 on the side of the mounting base 2; a base plate 4 disposed on the bottom surface of the mounting base 2, with multiple through holes on the upper surface of the base plate 4 for easy and stable installation with bolts; a base assembly 5 fixedly disposed on the upper surface of the base plate 4 for engaging with the welding robotic arm 1, enabling quick assembly and disassembly of the welding robotic arm 1; and a limiting component 6 fixedly disposed on the upper surface of the welding robotic arm 1 for limiting the position of the base assembly 5, thereby making the installation of the welding robotic arm 1 more stable.

[0030] like Figures 2 to 4 As shown, the base assembly 5 includes a base 51. Multiple through slots 52 are provided on the side of the base 51. An installation slot 53 is provided inside the through slot 52. A gear 54 is rotatably mounted inside the installation slot 53 to facilitate gear installation. A rack 55 is slidably mounted inside the through slot 52 for stable guidance of the rack 55. The rack 55 meshes with the gear 54 to facilitate movement of the rack 55. A gear ring 56 is rotatably mounted inside the base 51. The gear ring 56 meshes with the gear 54 to facilitate rotation of the gear 54. Multiple guide through slots 57 are provided on the outer wall of the gear ring 56. The guide through slots 57 are movably sleeved with the rack 55. The gear ring 56 is engaged with the card holder 2 to facilitate insertion and positioning of one end of the rack 55 into the slot 3.

[0031] like Figure 1 and Figure 2 As shown, the limiting component 6 includes a limiting ring 61 that is movably sleeved on the outer wall of the base 51, which can stably guide the limiting ring 61. The upper surface of the limiting ring 61 is provided with a first limiting groove 62, which can engage and limit one end of the rack 55. Multiple springs 63 are fixedly provided on the bottom surface of the limiting ring 61. One end of the spring 63 is fixedly connected to the base plate 4, which can push the limiting ring 61 to move vertically upward.

[0032] Furthermore, a set of annular guide rails 7 are fixedly installed inside the base 51. Annular guide grooves 8 are opened on the opposite surfaces of the annular guide rails 7. A guide ring 9 is slidably installed inside the annular guide grooves 8. The guide ring 9 is fixedly connected to the toothed ring 56 and can stably guide the toothed ring 56 to rotate.

[0033] Secondly, the outer wall of the card holder 2 is provided with multiple limiting blocks 10, and the inner ring surface of the toothed ring 56 is fixedly provided with multiple second limiting grooves 11, which enable the card holder 2 to drive the toothed ring 56 to rotate.

[0034] Furthermore, the bottom surface of the card holder 2 is fixedly provided with multiple limiting slots 12, and the inner bottom surface of the base 51 is provided with multiple limiting blocks 13, which can stably connect the card holder 2 and the base 51.

[0035] In addition, the limiting slot 12 and the limiting block 13 are designed with an "L" shape, which makes the locking more stable.

[0036] The working principle of this embodiment is as follows: During installation, the card holder 2 is first pressed down into the interior of the base 51. During the pressing process, the second limiting groove 11 and the limiting block 10 are engaged with each other, and at the same time, the limiting block 13 is inserted into the interior of the limiting groove 12. Then, the card holder 2 is rotated, and the card holder 2 drives the limiting block 13 to be stably engaged inside the limiting groove 12. Through the cooperation of the second limiting groove 11 and the limiting block 10, the card holder 2 drives the gear ring 56 to rotate. The gear ring 56 is engaged with the guide ring 9 through the annular guide groove 8 on the annular guide rail 7, so that the gear ring 56 rotates stably inside the base 51. Since the gear ring 56 meshes with the gear 54, and the gear 54 meshes with the rack 55, when the gear ring 56 has a tendency to rotate, it drives the gear 54 to rotate, thereby driving the rack 55 to slide in the through groove 52. The rack 55 moves along the guide groove 57 of the toothed ring 56, ensuring the stable rotation of the toothed ring 56, so that one end of the rack 55 is inserted into the slot 3 on the side of the card holder 2, and finally the card holder 2 and the base 51 are engaged and positioned.

[0037] Since one end of the rack 55 is inserted into the slot 3, the spring 63 in the limiting assembly 6 provides elastic force, causing the limiting ring 61 to move vertically upward through the guide of the base 51, so that the first limiting groove 62 on the limiting ring 61 engages with one end of the rack 55, thereby stably limiting the rack. When removing it, the operation is reversed, which will not be described in detail here.

[0038] No bolt tightening is required, which enables convenient installation, saves time and labor costs, improves production speed, ensures the stability of the entire welding robot arm during long-term operation, avoids weld deviation and weak welding, and improves welding accuracy.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
