Description

Technical Field

[0001] The present application relates to the technical field of parts processing, and in particular to a welding device for parts processing. Background Art

[0002] In the field of parts processing, welding, as a vital process method, is widely used in the connection process of various materials. At present, the three-axis welding system is one of the most common welding systems. Through the three-axis welding system, the welding gun can be flexibly moved in three-dimensional space, so that complex welding paths can be performed. Although the three-axis welding system can complete plane welding tasks, for annular surface welding that requires vertical rotation (such as cylindrical or tubular parts), it is usually necessary to cooperate with a rotating device or a positioner to complete the welding operation. This situation not only increases the equipment cost, but also affects the processing efficiency;

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0011] The rod fixture includes a central control chuck connected to the moving block through a transmission part, which is used to clamp the parts that need to be annularly welded. The transmission component converts the displacement of the moving block along the Y-axis direction into the circular rotation of the central control chuck.

[0012] Preferably, the frame is also provided with a plurality of guide rails slidably connected to the slide, which are used to guide the slide to move so that the slide can slide along the X-axis.

[0013] Preferably, the rod fixture further comprises a chuck fixing seat, the chuck fixing seat is mounted on the slide, and the central control chuck is rotatably disposed on the chuck fixing seat for clamping the rod-shaped part.

[0014] Preferably, the transmission component includes a transmission component 1 coaxial with the moving block, and a transmission component 2 that moves synchronously with the moving block.

[0022] The following is combined with Figure 1-3 This application is described in further detail.

[0023] The present application embodiment discloses a welding device for parts processing. Figure 1-3 A welding device for parts processing includes a frame 1 for overall support, a two-axis feeding system 2 is installed on the frame 1, a welding gun head 3 is driven to move in the X-axis and Z-axis directions by the two-axis feeding system 2, a welding gun head 3 is installed at the movable output end of the two-axis feeding system 2, and parts are welded by the two-axis feeding system 2. A docking assembly 4 is installed on the lower side of the welding gun head 3 on the frame 1, and the docking assembly 4 includes two slides 402 that move in the X-axis. The distance between the two clamping assemblies 5 is adjusted by the docking assembly 4. To adapt to parts of different lengths, a clamping assembly 5 is installed on both slides 402. The clamping assembly 5 includes a universal clamp 501 and a rod clamp 502. The universal clamp 501 is used to clamp and fix plate-shaped parts such as rod-shaped, flat-plate-shaped, and planar ring-shaped parts, and the rod clamp 502 is used to clamp and fix cylindrical, ring-shaped, tubular, polygonal column-shaped parts. A transmission component is provided between the universal clamp 501 and the rod clamp 502 to achieve synchronization between the translation of the universal clamp 501 and the rotation of the rod clamp 502.

[0024] By adopting the above technical scheme, through the coordinated use of the two-axis feeding system 2, the welding gun head 3, the docking assembly 4 and the clamping assembly 5, different types of workpieces can be clamped through the universal clamp 501 and the rod clamp 502, and the transmission between the universal clamp 501 and the rod clamp 502 is realized by using the gear 5023 and the rack 5024 to realize the conversion between linear motion and circular motion. In conjunction with the two-axis feeding system 2 driving the welding gun head 3 to move in two axes, planar welding and vertical annular welding of parts can be realized.

[0025] Referring to the frame 1, two parallel guide rails 401 are installed on the frame 1, and two slides 402 are slidably mounted on the guide rails 401. The slides 402 and the welding gun head 3 can both move along the X-axis to ensure that the welding gun head 3 can weld at different positions of the weld seams.

[0026] Reference Figure 2 The shaft feeding system 2, the universal clamp 501 includes a moving block 5012 and a screw rod 5011 installed on the slide 402. The screw rod 5011 and the moving block 5012 cooperate to drive the parts to move in the Y-axis direction, so that the welding gun head 3 can perform three-axis welding on the plate-like parts. A gantry 5013 is rotatably installed on the moving block 5012, and a pressure plate 5014 is installed on the inner side of the gantry 5013. A threaded rod 5015 is installed on the pressure plate 5014. The upper end of the threaded rod 5015 is threaded through the gantry 5013 and is connected to a screw handle. The pressure plate 5014 is driven up and down by twisting the screw handle to clamp and fix the plate-like parts.

[0027] Referring to the welding gun head 3, a driving motor 503 is installed on the side of the slide 402, and the end of the screw rod 5011 passes through the slide 402 and is connected to the driving motor 503. A guide rod 504 is installed on the side of the slide 402 where the screw rod 5011 is installed. The end of the guide rod 504 passes through the moving block 5012 and is slidably connected to the moving block 5012. The screw rod 5011 is driven to rotate by the driving motor 503, so that the moving block 5012 slides along the guide rod 504 to realize the plane welding of parts.

[0028] Referring to the welding gun head 3, the transmission component includes a gear 5023 fixedly mounted on the central control chuck 5022, and a rack 5024 fixedly mounted on the moving block 5012. The gear 5023 is meshed with the rack 5024. When the guide rod 504 drives the moving block 5012 to move, the rack 5024 drives the gear 5023 to rotate, thereby driving the central control chuck 5022 and the rod-shaped part to rotate, thereby realizing annular surface welding.

[0029] Reference Figure 2 The shaft feeding system 2, the rod fixture 502 includes a chuck fixing seat 5021 fixedly mounted on the slide 402, which is used to fix the chuck. A central control chuck 5022 is rotatably mounted on the chuck fixing seat 5021, and the rod-shaped parts can be clamped and fixed by the central control chuck 5022.

[0030] The implementation principle of a welding device for parts processing in the embodiment of the present application is as follows: when performing plane welding of parts, the two parts to be welded are placed on the corresponding universal clamps 501 respectively, the threaded rod 5015 is screwed to move the pressure plate 5014 downward, the two parts to be welded are clamped and fixed, and the slides 402 on both sides are moved to dock the parts. When welding, the welding gun head 3 is driven by the two-axis feeding system 2 to align with the gap to be welded. The two-axis feeding system 2 and the driving motor 503 work so that the welding gun head 3 can move in three axes relative to the welding parts to achieve plane welding. When performing annular surface welding, the two parts to be welded are placed in the corresponding central control chuck 5022 respectively, and the two-axis feeding system 2 and the driving motor 503 are used to drive the welding gun head 3 to align with the gap to be welded. The two central control chucks 5022 clamp and fix the two parts to be welded, and move the slides 402 on both sides to dock the parts. During welding, the two-axis feeding system 2 drives the welding gun head 3 to align with the gap to be welded. The two-axis feeding system 2 works with the drive motor 503, and the drive motor 503 drives the screw rod 5011 to rotate, so that the moving block 5012 drives the rack 5024 to move, and then drives the gear 5023 and the central control chuck 5022 to rotate, so that the parts to be welded rotate in a circle, and the welding gun head 3 is realized along the side of the parts to be welded. The welding system completes the planar three-axis and annular movement welding operations, which has the advantages of simple structure, low cost and high practicality.
