Description

Technical Field

[0001] The utility model relates to the technical field of spot welding devices, in particular to spot welding equipment for instrument shells. Background Art

[0002] During the production process of the instrument case, small parts need to be installed and assembled inside the instrument case by spot welding. In the existing technology, the small parts are fixed inside the instrument case by manually taking the spot welding equipment, but this method will generate sparks during the spot welding process, and the sparks are easy to splash on the workers' hands, which is easy to cause harm to the workers, thereby reducing the safety of the workers at work, and the use of manual spot welding also reduces the efficiency of spot welding; of course, there are also semi-automatic equipment that does not require manual electric welding, but during the feeding process, the instrument case is manually placed under the welding head of the electric welder. After welding, the instrument case is also manually removed from the position of the electric welding head. This method is due to the problem of working space because the instrument case is manually placed under the electric welding head. Because the temperature at the welding head of the welding head is high after the instrument case is welded, when it is manually taken, due to the limitations of the working space, it is easy for the staff to touch the electric welding head, thereby causing a safety hazard of burns, and this method will also lead to a decrease in work efficiency. To this end, the utility model proposes a spot welding device for instrument shells that can improve the efficiency of spot welding and has high safety. During the loading and unloading process, the staff does not need to approach the position of the welding head. The instrument shell to be welded is sent to the position of the spot welding head through an automated device, and the welded instrument shell is transported out and away from the spot welding head, thereby achieving an efficient and safe welding process.

[0026] During the use of the utility model, the instrument shell that needs to be spot welded is first placed in the welding protective cover 6 of the product positioning groove 401 on the welding base 4 by driving, and then the driving source 5 drives the two welding bases 4 to move simultaneously, and the welding base 4 with the instrument shell placed thereon is moved to the bottom of the spot welding mechanism 3, and then the driving source 5 drives the spot welding mechanism 3 to move downward along the guide rail 203 to the spot welding position, and the control unit 101 controls the spot welding mechanism 3 to perform spot welding on the instrument shell, and at the same time, the instrument shell that needs to be spot welded is placed on the other welding base 4 in an upper and lower manner.

When the spot welding is completed, the driving source 5 drives the two welding bases 4 to move simultaneously along the guide block 201, and moves the other welding base 4 to the bottom of the spot welding mechanism 3 to perform spot welding in an upper-continuation manner. At the same time, the worker lifts the product push block 601 and moves it upward along the welding protective cover 6. The product push block 601 drives the product drag plate 602 to move upward. The product drag plate 602 drags the instrument shell upward, and lifts the spot-welded instrument shell from the inside of the welding protective cover 6 to the outside. The worker takes the spot-welded instrument shell, and then replaces other instrument shells that need to be spot-welded and places them on the product drag plate 602, and releases the product push block 601.
