Description

Technical Field

[0001] This utility model relates to the field of laser welding machine technology, and specifically to a vertical welding device for a laser welding machine. Background Technology

[0002] Laser welding machines, also known as laser welders or laser arc welding machines, are used for laser welding in material processing. Laser welding utilizes high-energy laser pulses to locally heat a tiny area of ​​the material. The energy of the laser radiation diffuses into the material through heat conduction, melting the material to form a specific molten pool. It is a new type of welding method, mainly for welding thin-walled materials and precision parts. It can achieve spot welding, butt welding, lap welding, and sealing welding, with a high depth-to-width ratio, small weld width, small heat-affected zone, minimal deformation, fast welding speed, smooth and aesthetically pleasing welds, requiring no or only simple post-weld treatment, high weld quality, no porosity, precise control, small focused spot, high positioning accuracy, and easy automation.

[0003] Currently, existing laser welding devices cannot be adjusted vertically, and their own structure may block the welding light path, making it impossible to complete special weld seams and thus failing to meet welding requirements. Utility Model Content

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A vertical welding device for a laser welding machine includes a thrust ball bearing clamp, a cylinder, and an adjustment mechanism. The cylinder is mounted on the adjustment mechanism, and its telescopic end extends vertically downward and is connected to the thrust ball bearing clamp via a guide shaft. The thrust ball bearing clamp can rotate 360° horizontally.

[0007] The beneficial effects of this utility model are: during the welding process, the workpiece to be welded is placed in a set position, and then the cylinder and the thrust ball bearing clamp are adjusted to the set position by the adjustment mechanism so that the thrust ball bearing clamp is above the workpiece to be welded; then, the cylinder extends and retracts and drives the thrust ball bearing clamp to move downward until the thrust ball bearing clamp presses the workpiece to be welded, which makes welding convenient.

[0008] This utility model has a simple structure and reasonable design. According to the needs of vertical clamping welding, it realizes that the clamping device and the main body of the fixture have no direct contact connection and does not obstruct the welding optical path, thus completing the special weld welding.

[0020] Furthermore, it also includes a lower base plate, which is horizontally and fixedly installed below the upper base plate and is fixedly connected to the upper base plate by a support member.

[0021] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. The entire equipment is supported by the bottom plate and supporting components, so that the equipment can be used in conjunction with welding equipment.

[0022] Furthermore, the support member includes two upright plates, which are vertically arranged opposite each other between the upper base plate and the lower base plate, with their ends fixedly connected to the upper base plate and the lower base plate, respectively.

[0023] The advantages of adopting the above-mentioned further solution are that the structure is simple, the design is reasonable, and the upper and lower base plates are connected by two upright plates, making assembly convenient.

[0027] The beneficial effect of adopting the above-mentioned further solution is that, during use, the locking handwheel is manually loosened so that one end of it separates from the position adjustment locking plate, and then the slide rail base plate is manually slid to adjust the position of the entire device; then, the loosening locking handwheel is manually tightened to the position of the locking plate at one end, thereby realizing the positioning of the slide rail base plate, and thus realizing the positioning of the thrust ball bearing clamp.
