In the preferred technical scheme, servo gear motor can be selected for use to drive arrangement, thereby adjusts servo gear motor's speed through adjusting servo gear motor's duty cycle to satisfy the moving cone assembly 3 of different welding process demands or have the welding robot 2 of different welding parameters. The speed reducer of the servo motor 11 has the characteristics of high rigidity, high precision and high transmission efficiency, and can improve the precision and the reliability of the transmission device 13. And the interior of the servo speed reducing motor comprises a planetary speed reducing mechanism, so that the installation space is effectively saved. In another embodiment, the driving device includes a servo motor 11, a reducer 12 and a controller (fig. 2), and the main shaft 32 of the servo motor 11 is connected to the reducer 12 and connected to the transmission device 13 through the output shaft of the reducer 12. The controller controls the duty ratio of the servo motor 11 to adjust the rotating speed of the servo motor 11, and drives the moving cone assembly 3 by reducing the speed and increasing the torque through the speed reducer 12. In order to reduce the complexity and overall weight of the system, the transmission device 13 includes, but is not limited to, a transmission belt and a transmission chain.

In one preferred embodiment, the bracket is a one-piece bracket, the bracket 14 presents a shape like a Chinese character 'ao', two convex parts of the bracket are suitable for supporting a main shaft 32 of the movable cone assembly 3, and a movable cone body 31 of the movable cone assembly 3 is accommodated in a concave space in the middle of the bracket.

In another preferred embodiment, two of the trays 14 are included (fig. 1-3). The two brackets 14 are arranged at intervals and are respectively used for supporting the head end of the main shaft 32 and the tail end of the main shaft 32 of the movable cone assembly 3. The bracket 14 further includes a bracket body 142 and a bracket base 144 located at a lower portion of the bracket body 142, wherein the bracket base 144 is fixedly connected to the object stage 15 by a bolt. The object stage 15 is provided with strip-shaped bolt holes to facilitate adjustment of the position of the bracket 14. Since the movable cone assembly 3 is driven by the transmission device 13 to rotate, the contact position of the bracket 14 and the main shaft 32 needs to use the roller 141 so as to reduce the friction force thereof, and meanwhile, the rollers 141 have a limiting effect on the axis of the main shaft 32, so that the welding position inaccuracy caused by the inclination of the main shaft 32 is avoided. Specifically, the bracket body 142 is provided with a plurality of rollers 141 at an upper portion thereof, and preferably, two rollers 141 are provided. The bracket body 142 is trapezoidal and has uniform thickness, the long trapezoidal side of the bracket body 142 is fixedly connected with the bracket base 144, so that the support stability of the bracket body 142 is increased, triangular reinforcing ribs 143 are arranged on two side faces of the bracket body 142 in the thickness direction, one side of each triangular reinforcing rib 143 is connected with the bracket base 144, and the other side of each triangular reinforcing rib 143 is fixedly connected with the bracket body 142.

The middle portion of the stage 15 is used for supporting the moving cone assembly 3, and needs to have high strength, so that the middle platform 152 is easy to manufacture by using a steel plate or an alloy plate. The object table 15 also requires a platform for placing tools, which are generally of a relatively light weight. Meanwhile, the placed tool is often attached with mechanical impurities such as dust, and impurities such as welding slag can fall off in the welding process. Accordingly, the screen platform 151 is used on the side of the middle platform 152 to reduce the mass of the stage 15 while allowing mechanical impurities to drift through the screen to the ground to ensure the tidiness of the stage 15. The screen platform 151 includes a first screen 1511, a second screen 1512, and a third screen 1513, and the screen platform 151 is disposed around the middle platform 152 on three sides.

It should be noted that the moving cone body 31 of the moving cone assembly 3 is close to the end of the main shaft 32, and the weight of the moving cone assembly 3 is mainly concentrated on the end of the main shaft 32, so during the transportation, it is necessary to make the end of the main shaft 32 as close as possible to the transportation apparatus or the operator, and the head end of the main shaft 32 can be far away from the transportation apparatus or the operator than the end. Middle part platform 152 is used for supporting the minor face of moving cone assembly 3 one end does not be equipped with filter screen platform 151 to first filter screen 1511 is than the long limit of middle part platform 152 is short, so that middle part platform 152 is placed one side that main shaft 32 is terminal sets up operating personnel's the space that is close. The third screen 1513 may be divided into two separate parts to improve the force applied to the screen. Meanwhile, the third filter 1513 protrudes from the long side of the middle platform 152 to make up for the lost support space of the first filter 1511 shorter than the long side of the middle platform 152.
