Description

Technical Field

[0001] This utility model relates to the field of automatic welding machine technology, specifically to a rotating body of an automatic welding machine that is easy to assemble and disassemble. Background Technology

[0002] Electric welding machines use electrical energy, instantly converting it into heat energy. They are widely used in various fields due to their simple operation, ease of use, and strong welds. However, due to the limitations of their working principle, most electric welding machines currently in use are relatively bulky and unsuitable for certain specific work scenarios, such as welding intersecting seams within large pipelines. In such scenarios, the welding machine needs to be flexibly placed within the space where the pipelines intersect to weld saddle-shaped seams. Current welding technology is not suitable for such confined spaces. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic welding machine rotating body to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic welding machine rotating body that is easy to assemble and disassemble, comprising a centering cylinder, a three-jaw chuck, a rotary locking disc quick-release seat, and a welding machine rotating body. The three-jaw chuck inserts a three-jaw clip into the centering cylinder and is fixedly connected to the centering cylinder by the contraction and extension of the three-jaw clip. The lower end face of the rotary locking disc quick-release seat is fixedly connected to the upper end face of the three-jaw chuck, and the upper end face of the rotary locking disc quick-release seat is fixedly connected to the lower end face of the welding machine rotating body. The welding machine rotating body, the rotary locking disc quick-release seat, the three-jaw chuck, and the centering cylinder can be quickly assembled and disassembled.

[0005] The rotary locking disc quick-release base includes a quick-connect female and a quick-connect male. The quick-connect female is hollow inside, and its upper surface is provided with evenly distributed female baffles. Evenly distributed female notch spaces are provided between adjacent female baffles. Evenly distributed female mounting through holes are provided on the end face of the quick-connect female to facilitate bolt fixing to the upper surface of the three-jaw chuck. Evenly distributed female positioning through holes are provided on the side of the quick-connect female to facilitate screw connection and fixing to the quick-connect male. Evenly distributed male plates are provided on the lower end face of the quick-connect male, and evenly distributed male notch spaces are provided between adjacent male plates. Male screw positioning holes are provided on the side of the male plates to facilitate screw fixing to the female positioning through holes. Evenly distributed male mounting through holes are provided on the upper surface of the quick-connect male to facilitate screw fixing to the rotating body of the welding machine.

[0006] Preferably, the number of the female baffle, the fixed mounting female through hole, the female positioning through hole, the male plug plate, the fixed mounting male through hole, and the male screw positioning hole are all three.

[0007] The rotating body of the welding machine includes a base, a main motor, a reducer, a moving gear, a core cylinder, an upper cover, a transmission bearing, a transmission shaft, fixing bolts, anti-detachment washers, and a fixed gear. The base has a left mounting hole and a right mounting hole. A transmission bearing seat is located on the bottom surface of the left mounting hole. The main motor is connected to the reducer. The reducer is fixed in the right mounting hole. The transmission shaft of the reducer passes through the right mounting hole and is connected and fixed to the moving gear. The core cylinder covers the left mounting hole. An upper cover is connected to the upper end of the core cylinder. A transmission bearing seat is located on the upper cover.

The upper and lower end faces of the transmission shaft are provided with countersunk screw holes. A mounting through hole is provided at the center of the fixed gear. The fixed gear is fixed to the bottom surface of the base corresponding to the left mounting hole and meshes with the moving gear for transmission. Below the core cylinder, the fixing bolt passes through the anti-detachment washer, the fixed gear, and the countersunk screw hole in the transmission shaft to prevent displacement of the transmission bearing. Above the core cylinder, the fixing bolt passes through the anti-detachment washer and the countersunk screw hole in the transmission shaft to prevent displacement of the transmission bearing.

[0008] Furthermore, to ensure that the fixing bolt can be quickly aligned and connected to the countersunk hole on the drive shaft, a self-aligning bushing is also included. The self-aligning bushing abuts against the inner ring of the drive shaft, with a height equal to the thickness of the anti-loosening washer and an outer diameter not greater than the center hole of the anti-loosening washer. The fixing bolt passes through the self-aligning bushing and the anti-loosening washer and is connected to the countersunk hole on the inner screw of the drive shaft.
