[0002] A welding robot is an industrial robot engaged in welding. 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 order to adapt to different uses, the mechanical interface of the robot's last axis is usually a connecting flange, which can be connected to different tools or end effectors. The welding robot is an industrial robot with a welding clamp or welding gun installed on the end axis flange, so that it can perform welding, cutting or thermal spraying.

[0003] Currently, most welding robots on the market are installed on the workbench through flange rings. However, when the welding robot is working, the height of the external workbench is different. During use, the user is required to customize bases of different heights for support, which increases the limitations of the use of the welding robot and is not convenient to adjust the required welding angle according to needs, reducing its practicality.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 3 The utility model provides a technical solution: a welding robot that is easy to adjust, including a robot base 1, a connecting flange 2 is installed at the bottom of the robot base 1, a support shaft 4 is fixed at the top of the robot base 1, a screw rod 5 is slidably connected in the middle of the support shaft 4, a support seat 6 is installed on the top of the screw rod 5, a mounting block 7 is fixed on the top of the support seat 6, a fixed shaft 8 is fixed in the middle of the mounting block 7, a crank 9 is sleeved on the outside of the fixed shaft 8, a support shaft 10 is passed through the end of the crank 9, a connecting rod 11 is sleeved on the outside of the support shaft 10, a rotatable connecting handle 12 is provided at the end of the connecting handle 12, and an electric welding head 13 is installed at the bottom of the connecting handle 12.

[0031] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the surface of the connecting flange 2 is provided with a plurality of through holes 3 for facilitating the installation of bolts.

[0032] It should be noted that during use, the welding robot is installed and used with the workbench by bolts penetrating the connecting flange 2 .

[0033] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the outside of the robot base 1 is fixedly sleeved with a mounting seat 51, the bottom of the mounting seat 51 is fixed with a motor 52, the output end of the motor 52 is fixedly connected to a transmission rod 53, the outside of the transmission rod 53 is fixedly sleeved with a driving gear 55, and the end of the driving gear 55 is meshed with a driven gear 56.

[0034] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a support rod 54 is fixed to the top of the mounting seat 51, the support rod 54 is rotatably connected to the driving gear 55, the driven gear 56 is rotatably sleeved with the support shaft 4, the interior of the driven gear 56 is provided with a thread groove 1101 threadedly connected to the screw rod 5, a slide plate 57 is installed at the bottom of the screw rod 5, and fixing rods 58 are slidably embedded at both ends of the slide plate 57, and the fixing rods 58 are fixedly connected to the inside of the robot base 1.

[0035] It should be noted that the fixed rod 58 is used to guide and limit the sliding of the slide plate 57, and a cavity is provided inside the support shaft 4, and the screw 5 is placed in the cavity for rotation. The cavity provides a margin for the screw 5 to rotate, thereby avoiding limiting the rotational movement of the screw 5.

[0036] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a rotating shaft 1201 is fixedly connected in the middle of the connecting handle 12, and the rotating shaft 1201 is rotatably connected to the connecting rod 11. A fan-shaped rack 1202 is installed on the side end of the connecting handle 12, and a rotating gear 1203 is meshed at the end of the fan-shaped rack 1202. A rotating rod 1204 is fixed in the middle of the rotating gear 1203, and the rotating rod 1204 is rotatably connected to the connecting handle 12. A turntable 1205 is fixed at the end of the rotating rod 1204, and a threaded rod 1206 is connected to the internal thread of the turntable 1205.

[0037] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a thread groove 1101 is provided on the surface of the connecting rod 11 to facilitate the threaded connection of the threaded rod 1206 .

[0038] It should be noted that the threaded rod 1206 is placed in the thread groove 1101 and is threadedly connected, so that the threaded rod 1206 limits the turntable 1205 to prevent the turntable 1205 from rotating, thereby allowing the electric welding head 13 to be used stably after the angle is adjusted.

[0039] It should be noted that the specific model and specifications of the motor 52 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0040] The use method and advantages of the utility model: When the welding robot which is easy to adjust is working, the working process is as follows:

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the robot base 1 is installed and used with the ground through the connecting flange 2 and the bolts are passed through it, and then the use height is adjusted according to the needs, and the starting motor 52 drives the transmission rod 53 to drive the driving gear 55 to rotate, and the driving gear 55 then rotates around the support rod 54, and at the same time, the driving gear 55 is meshed with the driven gear 56 when rotating, and the driven gear 56 is forced to rotate around the support shaft 4. When the driven gear 56 rotates, the screw rod 5 inside it is threadedly matched with it, so that the screw rod 5 is forced to slide up, and at the same time, the slide plate 57 at the bottom slides up along the fixed rod 58, so that the upper end of the electric welding head 13 can be driven to adjust the height of the workbench according to the needs, so that it can be suitable for workbenches of different heights, reducing the limitations of use;

[0042] When adjusting the welding angle of the electric welding head 13, the manually rotating turntable 1205 drives the rotating rod 1204 to rotate. When the rotating rod 1204 rotates, the rotating gear 1203 sleeved on the outside rotates immediately, and engages with the fan-shaped rack 1202 on the outside of the connecting handle 12 during rotation. The connecting handle 12 is forced to drive the rotating shaft 1201 to rotate in the connecting rod 11, so that the electric welding head 13 at the bottom of the connecting handle 12 rotates immediately to adjust the welding angle, so that the required welding angle can be adjusted according to the needs, thereby improving its practicality.

[0043] After adjusting to the required position, the threaded rod 1206 is manually rotated to be rotated and embedded into the threaded groove 1101 of the connecting rod 11, so that it limits the turntable 1205, so that the welding head 13 can be used stably after adjustment, thereby improving the stability of use.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
