Description

Technical Field

[0001] The utility model relates to the field of laser welding heads, in particular to a hand-held laser welding head with angle adjustment. Background Technique

[0002] Laser welding is an efficient and precise welding method that uses a laser beam with a high energy density as a heat source. Laser welding is an important aspect of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process belongs to the heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses inward through heat conduction. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool.

[0003] For the existing hand-held laser welding head, it is troublesome to extend the laser welding head into a special space. The user needs to constantly try to change gestures to perform welding operations, so there is a lack of a structure that can flexibly adjust the tilt angle of the laser welding head to solve the above situation. Therefore, we propose a hand-held laser welding head with angle adjustment to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hand-held laser welding head with angle adjustment to solve the problems raised in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A hand-held laser welding head with angle adjustment, comprising: a welding gun body, two first brackets are fixedly connected to the top of the welding gun body, the same rotating block is rotatably connected inside the two first brackets, a welding gun head is fixedly connected to the top of the rotating block, a cylinder is fixedly connected inside the rotating block, and the same fixed column is fixedly connected between the two first brackets. A first groove is opened inside the fixed column, a first column is movably inserted into the first groove, two spherical columns are movably abutted against the outside of the first column, and two second grooves are opened on one side of the fixed column. The outside of the two spherical columns is slidably connected in the corresponding second grooves, and a plurality of circular grooves adapted to the spherical columns are opened inside the cylinder. The outside of the two spherical columns is movably inserted into the corresponding circular grooves.

[0007] Preferably, a small block is fixedly connected to one side of the fixed column, a circular plate is fixedly connected to the outside of the small block, the outside of the first column is slidably connected inside the circular plate, and a cross bar is fixedly connected to one side of the first column. The first bracket close to the small block is threadedly connected to the cross bar through a first bolt.

[0008] Preferably, two second rods are fixedly connected to one side of the fixed column. A second cylinder is slidably connected to the outer sides of the two second rods, and one side of each of the two second cylinders is fixedly connected to the outer side of the corresponding spherical column. Second springs are fixedly connected to the outer sides of the two spherical columns, and the other ends of the two second springs are fixedly connected to one side of the fixed column.

[0009] Preferably, a first cylinder is fixedly connected to the outer side of the first column. A first rod is slidably connected to the inner side of the first cylinder. The other side of the first rod is fixedly connected to one side of a circular plate. A first spring is fixedly connected to one side of the circular plate, and the other end of the first spring is fixedly connected to the outer side of the first column.

[0010] Preferably, a battery case is threadedly connected to one side of the welding gun body through a fixing bolt, and a plurality of small protrusions are integrally formed on the outer side of the bottom of the welding gun body.

[0011] Preferably, a sponge pad is fixedly connected to one side of the welding gun head, and a dial block is fixedly connected to one side of the first column.

[0012] In the present utility model, for the handheld laser welding head with angle adjustment, the angle of the welding gun head is adjusted by holding the sponge pad. At this time, the dial block is pressed inward, so that the first column starts to move towards the first groove. During this process, the first column starts to contact and squeeze the spherical column, so that the spherical column also starts to move from the second groove into the circular groove until the first column completely enters the first groove. At this time, the spherical column has also completely entered the circular groove. The first bolt is tightened to fix the cross bar and the first bracket.

[0013] In the present utility model, for the handheld laser welding head with angle adjustment, by loosening the first bolt and pulling the dial block, under the action of the first spring and the second spring, the first column and the spherical column automatically reset. At this time, the user continues to hold the sponge pad to adjust the angle of the welding gun head.

[0014] The structure of the present utility model is reasonably designed. Through the cooperation among the dial block, the spherical column, the first column, the cylinder, the fixed column and the rotating block, the angle of the welding gun head can be adjusted, thus facilitating the use by the user.

A plurality of circular grooves adapted to the spherical columns 16 are opened in the inner side of the cylinder 5. The outer sides of the two spherical columns 16 are movably inserted into the corresponding circular grooves.

[0023] In this embodiment, a small block 7 is fixedly connected to one side of the fixing column 6. A circular plate 8 is fixedly connected to the outer side of the small block 7. The outer side of the first column 9 is slidably connected to the inner side of the circular plate 8. And a cross bar 13 is fixedly connected to one side of the first column 9.
