Description

Technical Field

[0001] The present invention relates to the technical field of welding processing, and particularly to a welding processing device for an excavator robotic arm. Background Art

[0002] The boom is a working device of an excavator. Because the connecting arm connected to the frame is relatively long, it is commonly known as the "big arm". The main function of the excavator boom is to control the excavation, loading and other actions of the bucket. The excavator boom is generally of a box structure and is mainly composed of upper and lower main plates, two side plates on the side, a boom seat sleeve, a boom middle sleeve and other components. During the production process of the excavator boom, it is necessary to first assemble the various components of the excavator boom into a whole, then reinforce them by welding, and finally grind and trim them into shape. For the Chinese patent document with the publication number CN116618894A, it discloses an automated welding production line and production method for an excavator boom; its solution proposes a welding process flow for an excavator boom.

[0003] In the above solution and the prior art, for the welding work of the workpiece to be processed by the robotic arm, the workpiece is clamped by a corresponding clamping device, and then the welding head on the robotic arm is used to perform welding processing on the corresponding position. During this process, the fumes generated by welding cannot be correspondingly treated. When multiple devices perform welding operations simultaneously, it will affect the environment of the production workshop and pose certain potential safety hazards to the health of the staff. On the other hand, during the welding processing, the spattering of sparks will not only damage the equipment but also pose a threat to the inspecting staff. Moreover, for the gap position of the welded workpiece, it is necessary to quickly cool down the welding position to make it quickly solidify, so as to avoid slight deformation at the welding position after welding, and the residue particles at the welding position need to be cleaned in time. If it is cleaned after solidification, it will be very troublesome, which will all affect the welding quality of the excavator boom. Therefore, it is necessary to improve and optimize the robotic arm welding components.

Before that, the fixed bottom box 402 is pushed by the first telescopic control rod 401 so that the cover box 405 reaches the welding position. Then, the flue gas and sparks are adsorbed into the cover box 405. The flue gas enters the cover box 405 and is purified and discharged through the arranged flue gas purification cotton disc 406. For solid particles such as sparks, they enter the slag filtering holes 407. During this process, the anti-blocking conical inclined body 4073 arranged in the slag filtering holes 407 blocks most of the slag.

Moreover, there will still be some residual smoke at the welded position, which can be timely absorbed and purified. Finally, the fixed bottom box 402 is pulled back by the first telescopic control rod 401. After long-term use, the dust, impurities and particles adhering to the flue gas purification cotton disc 406 will not only contaminate the surface of the flue gas purification cotton disc 406, but also affect its air permeability. Either it is replaced, that is, the cover box 405 is removed from the fixed bottom box 402 and the flue gas purification cotton disc 406 is replaced. Or the handle 409 drives the connecting body 411 to move, so that the movable body 414 connected and arranged in the connecting body 411 and the auxiliary rollers 416 arranged at the bottom end of the movable body 414 squeeze and scrape the impurities and condensed particles adhering to the flue gas purification cotton disc 406. And the anti-blocking convex particles 417 arranged on the wheel surface of the auxiliary rollers 416 are used to improve the convenience of removing the condensed particles.

One is arranged at the end of the connection soft brush 509, and the other is arranged at the middle position of the connection soft brush 509; here, after welding is completed, the useless slag and impurities generated on the side of the gap welding position need to be cleaned in time. That is, the second telescopic control rod 505 is used to push the rotation control motor 507 forward until the bearing sphere 508 at the end of the rotation control motor 507 reaches an appropriate position. And during the forward movement, the rotation control motor 507 can be started. The rotation control motor 507 drives the bearing sphere 508 to rotate.
