Technical Field

[0001] The utility model relates to the technical field of frame welding, in particular to a welding device for frame processing. Background Art

[0002] There are many kinds of mechanical equipment. When the mechanical equipment is running, some of its parts or even the equipment itself can perform different forms of mechanical movement. Mechanical equipment is generally composed of drive device, speed change device, transmission device, working device, brake device, protective device, lubrication system, cooling system and other parts. The welding rack is used to support and fix the welding machine, usually including support plate, placement plate and base. The placement plate is used to place and fix the welding machine. The welding rack is widely used.

[0003] The Chinese patent with the announcement number CN219805576U discloses a welding device for frame processing, which includes an operating table and a clamping assembly, wherein a movable groove is provided at the upper end of the operating table, and the clamping assembly for clamping an object is arranged inside the movable groove, and the clamping assembly includes a connecting column, a first cylinder, a clamping block and anti-skid particles, wherein the upper end of the connecting column is provided with a first cylinder, and the upper end of the first cylinder is provided with a clamping block, and the end of the clamping block is provided with anti-skid particles, and support columns are provided on both sides of the operating table. The welding device for frame processing can fix the position of the frame to be processed on the operating table by providing a clamping assembly, and can clamp and fix it to avoid position deviation during the welding process, which affects the welding work between the frames, and can absorb the gas generated during the welding process by providing a vacuum cleaner, thereby reducing the discomfort caused by gas absorption by the human body, and at the same time can improve the cleanliness of the device.

[0004] With respect to the above-mentioned related technologies, in the prior art, the staff uses a clamping block to clamp the side wall of the frame to realize the installation of the frame on the welding table. As the welding device is used for a long time, the clamping block will give way when it is pressed against the frame, resulting in the possibility of the frame tilting when it is clamped. However, there is no technical means to prevent the frame from tilting in the prior art. There is a possibility of shaking or deviation during the welding of the frame, which makes the processing of the frame unable to meet its process requirements, reducing the welding effect of the welding device.

The positioning member 31 is a positioning frame, which is welded on the operating table 1, and the length direction of the positioning member 31 is parallel to the moving direction of the welding gun 2. A plurality of support rods 311 are welded between the positioning member 31 and the operating table 1, and three are used as an example in this embodiment.

[0033] Reference Figure 1 , Figure 2 and Figure 3 , there are two groups of clamping assemblies 32, and the two groups of clamping assemblies 32 are arranged opposite to each other. The clamping assemblies 32 include a moving seat 321, a swing rod 322 and a driving member 323. A limiting groove 11 is opened on the operating table 1, and the moving seat 321 is slidably fitted in the limiting groove 11. A moving assembly 4 is arranged on the operating table 1, and the moving assembly 4 includes a moving motor 41, a driving screw 42 and a limiting member 43. The driving screw 42 is rotatably connected to the bottom wall of the operating table 1 and is located directly below the limiting groove 11. The driving screw 42 is parallel to the limiting groove 11, passes through the moving seat 321, and is threadedly matched with the moving seat 321. The moving motor 41 is fixedly connected to the bottom wall of the operating table 1, and the moving motor 41 is coaxially connected to one end of the driving screw 42.

[0034] Reference Figure 2 The limiting member 43 is a limiting steel, and a plurality of limiting members 43 are connected by bolts on both opposite side walls of the moving seat 321. In this embodiment, two limiting members are used as an example, and the operating table 1 is located between the two limiting members 43 on the same side. A plurality of balls 431 are embedded on the side wall of the limiting member 43 close to the operating table 1, and the balls 431 abut against the surface of the operating table 1.

[0035] Reference Figure 2 and Figure 3 The swing rod 322 is hinged to the top of the moving seat 321, and a driving slot 3221 is formed at one end of the swing rod 322. The driving member 323 is a driving cylinder, and the driving member 323 is mounted on the top of the moving seat 321. The output shaft of the driving member 323 is fixedly connected with a driving rod 3231, and the driving rod 3231 is slidably fitted in the driving slot 3221. A pressing plate is welded to the other end of the swing rod 322.

[0036] When installing the rack, the staff puts the side wall of the rack against the positioning piece 31, then starts the moving motor 41 to rotate the driving screw 42, and moves the moving seat 321 to one side of the rack. Then, the driving piece 323 is started to move the driving rod 3231, which drives the swing rod 322 to rotate, so that the pressure plate presses the rack, thereby completing the installation of the rack.

[0037] Reference Figure 1 and Figure 4In order to better install the rack, the positioning member 31 is provided with a plurality of abutting assemblies 5. In this embodiment, two are taken as an example. The abutting assemblies 5 include a rotating plate 51, a abutting rod 52 and abutting plate 53. The rotating plate 51 is an L plate. One end of the rotating plate 51 is hinged on the positioning member 31. The abutting rod 52 passes through the rotating plate 51 and is threadedly engaged with the rotating plate 51. One end of the abutting rod 52 is fixedly connected to a rotating wheel. The abutting rod 52 is threadedly engaged with a locking nut 521.
