Description

Technical Field

[0001] The utility model belongs to the technical field of welding accessories, and in particular relates to a floating welding mechanism. Background Art

[0002] Welding is the process of connecting metal parts using various fusible alloys (solder). In order to save manpower and improve efficiency, welding equipment is currently used for welding.

[0003] Technicians in related fields know that in the welding work of the nut welding machine, the upper electrode and the lower motor need to be in uniform contact with the sheet metal to achieve current conduction and then welding. However, after long-term use, the upper electrode or the lower electrode will be worn due to frequent contact with the sheet metal. In view of this wear, if the position of the upper electrode or the lower electrode is not fine-tuned, qualified welding will not be possible, and this wear is uncontrollable, so it will be difficult to ensure product consistency if the tooling is not replaced regularly, and frequent replacement of the tooling will lead to increased costs. Therefore, how to ensure that the upper electrode and the lower electrode can still perfectly contact the sheet metal when worn is the technical problem that this application wants to solve.

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 , Figure 2 As shown, a floating welding mechanism of the utility model comprises two fixed brackets 1 installed in parallel, a fixed connecting plate 2 is installed at the end of the fixed bracket 1, a bottom plate 3 is installed on the fixed bracket 1, guide rods 4 are slidably installed at both ends of the bottom plate 3, a floating plate 5 is slidably installed on the two guide rods 4, a spring 6 is installed between the floating plate 5 and the bottom plate 3, the spring 6 is sleeved on the outside of the guide rod 4, and a bracket 7 is installed on the upper side of the floating plate 5;

[0023] A mounting frame 8 is installed on the side of the floating plate 5 , and a sensor 9 is installed on the mounting frame 8 .

[0024] In this implementation case, when a floating welding mechanism is used, the fixed bracket 1 is first installed on the nut welding machine through the fixed connecting plate 2, and then the use is started, the sheet metal part is placed on the bracket 7, and then the operator moves the sheet metal part so that the hole for welding the nut on the sheet metal part finds the lower positioning pin of the nut welding machine, that is, the sheet metal part is positioned, and then the nut welding machine runs to convey the nut. When the sensor 9 senses a signal, it indicates that the nut conveyor conveys the nut in place, and the nut welding machine starts to run;

[0025] The upper electrode of the nut welding machine descends, driving the floating plate 5 to descend together so that the metal parts placed on the bracket 7 are in contact with the lower electrode of the nut welding machine, and then power is turned on to achieve the welding purpose. After the welding is completed, the upper electrode is withdrawn and the operator takes the parts;

[0026] During the descent, supported by the spring 6, the descent is smooth, and a buffer is ensured when the upper electrode and the lower electrode contact each other to prevent damage caused by a hard collision. Moreover, due to the floating effect of the floating plate 5, even when the lower electrode or the upper electrode is worn, the contact between the upper electrode and the lower electrode and the sheet metal can be ensured, thereby reducing maintenance costs.

[0027] Preferably, the bracket 7 is U-shaped, and a support rod 10 is installed on the bracket 7. The support rod 10 is adjustably installed on the bracket 7. Such a design can fine-tune the placement height of the sheet metal part. In fact, the structural shape of the bracket 7 can also be considered according to specific circumstances.

[0028] Preferably, a linear bearing 11 is installed at the sliding matching position between the base plate 3 and the guide rod 4. Such a design makes the guide rod 4 slide more smoothly. In fact, a structure that ensures smooth sliding can also be considered according to specific circumstances.

[0029] Preferably, an insulating plate 12 is installed between the fixed connecting plate 2 and the fixed bracket 1. Such a design is to ensure that there is no shunting during welding. In fact, insulation measures can also be considered according to specific circumstances.

[0030] Preferably, baffles 13 are installed at both ends of the guide rod 4. Such a design prevents the guide rod 4 from overtravelling and escaping. In fact, the installation method of the baffles 13 can also be considered according to specific circumstances.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
