[0014] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0015] like Figure 1As shown, it is a schematic diagram of the structure of the automatic welding machine for the distribution plate provided by the utility model. The automatic welding machine for the distribution plate includes a machine platform 10, a rotating clamping assembly 20 arranged in the machine platform 10, a positioning assembly 30 arranged on one side of the rotating clamping assembly 20, a welding gun assembly 40 arranged on one side of the rotating clamping assembly 20, and a dust collector 50 arranged on one side of the machine platform 10. It can be imagined that the automatic welding machine for the distribution plate also includes some other functional modules, such as a power supply module, an air supply module, etc., which are technologies already known to those skilled in the art and will not be described one by one here.

[0016] See also Figure 2 It should be noted that the automatic distribution plate welding machine is used to weld a distribution plate 60 on the surface of a casting cover plate 70. Specifically, the rotating clamping assembly 20 clamps the casting cover plate 70, the distribution plate 60 is placed on the casting cover plate 70, and is positioned by the positioning assembly 30, and then the welding gun assembly 40 performs all-round welding, and finally the dust collector 50 collects the welding smoke in the machine 10.

[0017] The machine 10 is a sealed box with two sliding doors 11, so that the distribution plate 60 and the casting cover plate 70 can be taken in and out through the sliding doors 11. Various components used for welding operations are placed in the machine 10, and the sealed box state can prevent the welding smoke generated during the welding operation from leaking out, thereby protecting the environment and production safety.

[0018] The rotary clamping assembly 20 includes a rotary motor 21 and a three-jaw pneumatic chuck 22 disposed at the output end of the rotary motor 21 .

[0019] The rotating motor 21 can drive the three-jaw pneumatic chuck 22 to rotate, so that the distribution plate 60 and the casting cover plate 70 can be welded in all directions, thereby improving the welding accuracy.

[0020] The clamping position of the three-jaw pneumatic chuck 22 matches the circumferential outer side wall of the casting cover plate 70, thereby clamping and fixing the casting cover plate 70. The working principle of the three-jaw pneumatic chuck 22 is the prior art and will not be described in detail here.

[0021] The positioning assembly 30 includes at least three transverse cylinders 31 arranged at intervals around the circumference of the rotating clamping assembly 20, at least three bearing plates 32 respectively arranged at the output ends of the transverse cylinders 31, at least three rollers 33 rotatably arranged at the ends of the bearing plates 32, a positioning bracket 34 arranged on one side of the rotating clamping assembly 20, a vertical cylinder 35 arranged on the positioning bracket 34, a connecting plate 36 arranged at the output end of the vertical cylinder 35, and a pressure plate 37 rotatably arranged on one side of the connecting plate 36.

[0022] The output directions of the three transverse cylinders 31 are toward the central axis of the three-jaw pneumatic chuck 22 , so that the three transverse cylinders 31 can respectively drive the three bearing plates 32 and drive the three rollers 33 to reciprocate toward the direction of the three-jaw pneumatic chuck 22 .

[0023] The three rollers 33 correspond to the distribution plate 60 placed on the melting and casting cover plate 70, so that under the drive of the transverse cylinder 31, the circumferential outer walls of the three rollers 33 abut against the circumferential outer walls of the distribution plate 60, thereby positioning the distribution plate 60 in the horizontal direction to ensure that the distribution plate 60 and the melting and casting cover plate 70 are in a concentric position.

[0024] The output direction of the vertical cylinder 35 is parallel to the central axis of the three-jaw pneumatic chuck 22 and faces the three-jaw pneumatic chuck 22. The vertical cylinder 35 can drive the connecting plate 36 and drive the pressure plate 37 to reciprocate toward the three-jaw pneumatic chuck 22.

[0025] The central axis of the pressure plate 37 is colinear with the central axis of the three-jaw pneumatic chuck 22, so that under the drive of the vertical cylinder 35, the lower surface of the pressure plate 37 abuts against the upper surface of the distribution plate 60, thereby positioning the distribution plate in the vertical direction, further stabilizing the distribution plate 60, and improving welding accuracy.

[0026] The welding gun assembly 40 includes a guide rail 41 arranged on the machine platform 10, a slider 42 slidably arranged on the guide rail 41, a support rod 43 fixedly arranged on the slider 42, an adjustment block 44 slidably arranged on the support rod 43, a connecting rod 45 passing through the adjusting block 44, a welding gun clamp 46 slidably arranged on the connecting rod 45, and a welding gun 47 clamped on the welding gun clamp 46.

[0027] The length direction of the guide rail 41 , the length direction of the support rod 43 , and the length direction of the connecting rod 45 are perpendicular to each other, so that the position of the welding gun 47 can be adjusted in a three-dimensional space.

[0028] A screw is disposed on one side of the guide rail 41 , and the slider 42 is fixed or loosened by twisting the screw, so that the welding gun 47 is adjusted in the length direction of the guide rail 41 .

[0029] A screw is disposed on one side of the adjusting block 44 , and the adjusting block 44 is tightened or loosened by twisting the screw, so that the welding gun 47 is adjusted in the length direction of the bracket rod 43 .

[0030] The welding gun clamp 46 can be directly located on the connecting rod 45 and slide, and the position of the welding gun clamp 46 on the connecting rod 45 is fixed by the weight of the welding gun clamp 46 and the welding gun 47 itself, so as to adjust the welding gun 47 in the length direction of the connecting rod 45.

[0031] The output direction of the welding gun 47 is toward the circumferential abutment between the distribution disk 60 and the casting cover plate 70, so that under the drive of the rotating motor 21, the distribution disk 60 and the casting cover plate 70 rotate, and the welding gun 47 starts and performs welding operation on the circumferential abutment between the distribution disk 60 and the casting cover plate 70.

[0032] The dust collector 50 is connected to the machine platform 10 via a ventilation pipe 51 . After the welding operation is completed, the dust collector 50 starts to work and absorbs the welding smoke inside the machine platform 10 through the ventilation pipe 51 .

[0033] The automatic distribution plate welding machine also includes a welding wire machine 80 arranged on one side of the machine platform 10. The welding wire machine 80 can supplement the welding wire raw materials to the welding gun 47, thereby realizing the function of sustainable production.

[0034] Compared with the prior art, the automatic distributor plate welding machine provided by the utility model clamps the casting cover plate 70 through the rotating clamping assembly 20, the distributor plate 60 is placed on the casting cover plate 70, and is positioned by the positioning assembly 30, and then the welding gun assembly 40 performs all-round welding on the circumferential abutment between the distributor plate 60 and the casting cover plate 70, and finally the dust collector 50 collects the welding smoke in the machine 10. The welding machine only needs to manually place the distributor plate 60 and the casting cover plate 70 in the machine 10 to automatically complete the welding operation, thereby improving the welding accuracy and welding efficiency.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
