Description

Technical Field

[0001] The utility model belongs to the technical field of laser beam processing welding auxiliary devices for IPC classification B23K 26 / 00, and particularly relates to a structural innovation and improvement technology of a support connecting frame device with an adjustable and extended laser processing improved gun head. Background Art

[0002] Laser processing is a mechanical processing method that uses laser as a heat source, that is, the laser heat source is the main body, and the surface of the workpiece is partially melted to achieve the process effect of connection, conduction, and reinforcement. In production, laser welding has the characteristics of fast welding speed, easy to be guided by the optical system, high precision, small deformation, and low thermal stress on the workpiece. Laser processing technology is gradually replacing traditional welding technology. Laser processing technology has been widely used in industrial production, especially for metal welding, cutting, drilling, marking and surface treatment.

[0003] At present, the functions of traditional laser processing equipment gun heads are relatively simple, especially the gun head mouth structure is relatively short. Under some working conditions, when the laser processing point of the workpiece product is deeper, there will be interference in use, and the laser processing equipment gun head is difficult to accurately position. In addition, after the existing laser processing equipment gun head is used for a long time, there will be welding slag residue near the inner wall near the gun head, which will affect the state of the welding point, and it needs to be disassembled and cleaned after a period of use.

[0004] Patent application 202321254513.6 relates to a stepped extended nozzle, including a positioning step, and a laser mechanism is fixedly arranged at the top center position of the positioning step. In the utility model, an extended nozzle is installed at the bottom of the butt-joint tube so that products with various solder joint depths can be welded, and the tin balls can be divided into the feed pipe through the ball distribution plate, so that the tin balls can fall from the butt-joint tube into the extended nozzle, and then inert gas can be introduced into the extended nozzle through the air inlet pipe. When the tin ball falls to the center position of the nozzle block, the laser mechanism can emit a laser to melt the tin ball, and the melted tin ball will be blown out by the inert gas and sprayed onto the surface of the product. A guide plate is arranged in the extended nozzle to guide the inert gas, so that an air film can be formed at the air outlet groove to prevent a large number of melted tin balls from remaining at the nozzle mouth, thereby reducing the frequency of cleaning the nozzle.

[0005] The existing laser processing gun heads basically have no lengthening and adjustment structure, and most of the existing gun head connection structures are troublesome to disassemble and install. And a few improvement measures will cause structural instability after lengthening. Utility Model Content

[0006] The technical problem to be solved by the present invention is that in response to the above-mentioned existing problems and technical needs, the present invention proposes an adjustable and extended support connecting frame for an improved laser processing gun head, which can adjustably increase and extend the length of the gun body and the gun head, thereby solving the practical technical problem of effectively increasing the feed length of the laser processing head.

[0007] To this end, the utility model includes: a gun head, a sleeve extension rod, an extension bracket and an extension connecting frame. The sleeve extension rod is composed of at least two mutually nested sleeves, and the sleeve positions of the two adjacent sleeves form a sleeve joint seam surrounding the outer wall; the bottom end of the extension bracket is provided with a ring mouth sleeved on the outer wall of the sleeve extension rod, and the upper section of the extension bracket is overlapped and connected to the lower end of the extension connecting frame. Further, the bottom end ring mouth of the extension bracket is a closed circular ring shape, or a closed rectangular shape, or a groove-type structure with an open bottom, or a groove-type structure with an open side.

[0008] Among them, the rear end face of the rear section of the sleeve extension rod is welded to the rear end face of the robot arm, or the rear end face of the rear section of the sleeve extension rod is fixed to the rear end face of the robot arm by screws; the front end section of the sleeve extension rod is welded to the rear end face of the gun head, or the front end section of the sleeve extension rod is screwed to the rear end of the gun head.

[0009] The middle sections of the extended pull frame and the extended connecting frame are provided with adjustment slots which are round holes. Alternatively, the middle sections of the extended pull frame and the extended connecting frame are provided with adjustment slots with long strip sliding slot structures.

[0010] The upper section of the extended pull frame and the lower end of the extended connecting frame are provided with corresponding screw holes on both sides and are connected by overlapping connection screws. Further, at least two groups of optional connection screw positioning connection screw holes are provided on the lower section of the extended connecting frame.

[0011] A connecting seat is fixed on the upper end of the extended frame.

[0012] Furthermore, in order to achieve the above-mentioned purpose, the present invention is configured as follows:

[0013] In particular, radial fastening holes are provided on the lower edge of the extended pull frame to install positioning edge screws.

[0014] Particularly, an adjusting bolt is used to penetrate the adjusting slot circular holes which are overlapped and aligned with the extension pulling frame and the extension connecting frame.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The gun head connection structure is lengthened by the sleeve extension rod, which effectively increases the length of the gun body. The sleeve extension rod is connected and reinforced by the extension frame, and the installation and adjustment are flexible and convenient, avoiding interference in the movement of the gun head and ensuring the quality of laser precision processing. The laser processing gun head can be accurately fed in place with adjustment, which makes it easy to achieve the optimal distance and angle parameters of laser processing. Moreover, the additional extension and support structure have convenient and stable auxiliary extension mechanisms. The installation, maintenance and adjustment are simple and quick. When the installation structure needs to be cleaned, it can be easily disassembled and assembled through the embedded and screwed structures, and the extension can be quickly disassembled, so as to facilitate the regular cleaning of welding slag and improve the efficiency of installation.
