[0002] An automated welding robot is an industrial robot engaged in welding (including cutting and spraying). It is a multi-purpose, reprogrammable automatic control operating machine with three or more programmable axes. It is used in the field of industrial automation. In some industrial production workshops with a high degree of automation, corresponding automated welding robots will also be equipped to perform automated welding work.

[0003] Announcement No. "CN219582009U" provides an automated welding robot that can achieve multi-axis automation by being equipped with a first cantilever, a second cantilever and a connecting arm. The welding gun can revolve around the welding workpiece without the need for a positioner to be mounted and engaged, and no manual welding is required, thereby improving the factory's production efficiency.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although this automated welding robot can automatically perform multi-axis welding work, the base of the automated welding robot is not provided with a corresponding ventilation and heat dissipation structure, which causes the rotating motor inside the base to easily accumulate heat and overheat during operation, thereby affecting the service life of the rotating motor. Secondly, the welding gun in the automated welding robot is not convenient to disassemble, assemble and replace during use, and the maintenance convenience is low. Utility Model Content

[0006] The purpose of the present utility model is to provide an automated welding robot for industrial workshop processing, so as to solve the problems raised in the above background technology.

The material of the mounting block 65 is the same as that of the welding gun head 5. A blocking cover 66 is installed at the front end of the connecting head 61, and the mounting block 65 facilitates the blocking cover 66 to block and position the welding gun head 5 to prevent the welding gun head 5 from loosening and slipping during use.

[0035] The annular side of the connector 61 is provided with a connecting external thread 62, and the inner annular side of the blocking cover 66 is provided with a connecting internal thread 69, and the connecting internal thread 69 matches the connecting external thread 62.

The connecting head 61, the blocking cover 66 and the locking screw 68 are all made of heat-resistant alloy. The connecting head 61, the blocking cover 66 and the locking screw 68 are all made of heat-resistant alloy and have good high temperature resistance, which can prevent melting and deformation during use.

[0036] Working principle: In the process of processing external parts in an industrial workshop, an automatic welding robot body 1 is required to weld the specified positions of the external parts. During the operation of the automatic welding robot body 1, the servo motor 8 will drive the automatic welding robot body 1 to rotate and turn through the connecting shaft 7. During this process, the connecting shaft 7 will drive the transmission shaft 47 to rotate through the active bevel gear 41 and the driven bevel gear 42, and the transmission shaft 47 will drive the ventilation fan blades 46 to rotate together, so that the rotating ventilation fan blades 46 will discharge the heat inside the support base 2 through the ventilation cavity 49. When the ventilation fan blades 46 rotate in the opposite direction, the external air will be sucked into the support base 2 through the ventilation cavity 49, thereby actively ventilating and cooling the support base 2, thereby avoiding the servo motor 8 inside the support base 2 from overheating during use. Thermal conditions; when installing the welding gun head 5, the maintenance personnel first insert the tail of the welding gun head 5 into the installation cavity 64 from front to back. At this time, the mounting block 65 will also be inserted into the limit groove 63, and then the blocking cover 66 is rotated and fixed to the front end of the connecting head 61 by connecting the external thread 62 and the connecting internal thread 69, so that the blocking cover 66 blocks and fixes the welding gun head 5 through the mounting block 65, and finally tightens the locking screw 68 into the internal threaded through hole 67 with the help of an external wrench, so that the locking screw 68 can lock the blocking cover 66 to prevent the blocking cover 66 from loosening due to self-rotation, thereby ensuring the stability of the blocking cover 66 to the welding gun head 5. When the welding gun head 5 needs to be disassembled and replaced, the maintenance personnel first loosens the locking screw 68 with the help of an external wrench, and then loosens and removes the blocking cover 66. At this time, the welding gun head 5 can be dragged, disassembled and replaced.
