Technical Field
[0001] This utility model relates to the field of automobile manufacturing equipment technology, and more specifically to a device for preventing errors in the welding of bolts on a white body. Background Technology
[0002] As the skeletal structure of a car, the manufacturing quality of the body-in-white directly affects the safety performance and service life of the entire vehicle. Bolting is an indispensable connection process in body-in-white manufacturing, widely used for mounting points on the frame, chassis, and various accessories. This process requires the precise welding of specific-sized bolts onto the body panels using projection welding or stud welding techniques, providing a reliable connection foundation for subsequent assembly. Because automotive components require extremely high assembly precision, with errors at some critical mounting points needing to be controlled within 0.05mm, the positional accuracy, correct specifications, and welding quality of bolts are particularly important. Incorrect bolt welding (including incorrect specifications, incorrect placement, or missed welds) not only affects subsequent assembly processes but may also lead to a decline in the overall vehicle safety performance.

[0015] 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.
[0016] Refer to the instruction manual appendix Figure 1-5 This utility model provides a device for preventing errors in welding bolts for a white body, including an error-prevention component for welding bolts for a white body. The error-prevention component includes a guide plate 1, and a connector for connecting welding equipment is installed at the bottom of the guide plate 1. A guide hole 2 is provided at the top of the guide plate 1, and an auxiliary component for adjusting the hole diameter is provided inside the guide hole 2. The movable retaining ring 5 and the fixed retaining ring 4 are fixedly assembled on the welding equipment by a fastening bolt 6 to ensure the stability of the guide plate 1. The guide hole 2 on the guide plate 1 provides precise guidance, thereby ensuring the accuracy of the welding equipment when welding the workpiece.
[0017] When using the aforementioned equipment to enhance the precision of welding bolts on a white body, the operator needs to assemble the guide plate 1 onto the welding equipment. Therefore, the connecting component includes two fixing posts 3, which are respectively installed at the bottom of both ends of the guide plate 1. A common fixing ring 4 is fitted around the bottom of each of the two fixing posts 3, and a movable ring 5 is rotatably connected to the front end of one end of the fixing ring 4. A fastening bolt 6 is provided at the front end of one end of the movable ring 5, and the rear end of the fastening bolt 6 passes through the movable ring 5 and extends into the interior of the fixing ring 4. The fastening bolt 6 is threadedly connected to the fixing ring 4. In this way, the guide plate 1 can be placed on the lower electrode grip on the welding equipment, and the fixing ring 4 and movable ring 5 can be fitted onto the lower electrode grip. The fastening bolt 6 secures the movable ring 5 and the fixing ring 4, thus firmly assembling the movable ring 5 and the fixing ring 4 onto the lower electrode grip, ensuring the stability of the guide plate 1. Precise guidance is then achieved through the guide holes 2 on the guide plate 1, ensuring the precision of the welding equipment when welding the workpiece.
[0018] Meanwhile, to effectively adapt to welding workpieces of different specifications, an auxiliary component is needed to adjust the diameter of the guide hole 2. This auxiliary component includes an outer ring 7 disposed within the guide hole 2, with the outer ring 7 threadedly connected to the inner wall of the guide hole 2. The outer ring 7 contains an inner ring 8 and a middle ring 9, with the middle ring 9 positioned between the inner ring 8 and the outer ring 7. Multiple spaced outer clamping plates 10 are installed on the outer top of the middle ring 9, and an outer clamping groove 11 is formed on the top of the outer ring 7 corresponding to one of the outer clamping plates 10, with the outer clamping plates 10 positioned inside the outer clamping groove 11. Multiple inner clamping plates 12 arranged in a circular array are installed on the outer top of the inner ring 8, and an inner clamping groove 13 is formed on the top of the middle ring 9 corresponding to one of the inner clamping plates 12, with the inner clamping plates 12 positioned inside the inner clamping groove 13.
[0019] In this way, the inner ring 8 and middle ring 9, which are limited by the inner clamping plate 12 and inner clamping groove 13, and the outer clamping plate 10 and outer clamping groove 11, can be removed one by one. The outer ring 7, which is threadedly connected to the guide hole 2, can also be rotated and removed. This allows the diameter of the guide hole 2 to be adjusted, which is convenient for adjusting the diameter according to the welding needs of different workpieces and improves the practicality of this product.
[0020] To improve the ease of rotating and disassembling the outer ring 7, an adjusting ring 14 is fitted around the bottom of the outer ring 7, and the adjusting ring 14 has multiple spaced anti-slip grooves machined on its exterior. This anti-slip grooves enhance the stability of rotating the adjusting ring 14 and also improve the ease of assembling and disassembling the outer ring 7.
[0021] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
