Detailed Description
In order that the objects and advantages of the invention will be more clearly understood, the following description is given in conjunction with the accompanying examples. It is to be understood that the following text is merely illustrative of one or more specific embodiments of the invention and does not strictly limit the scope of the invention as specifically claimed.
As used herein, the terms "parallel," "perpendicular," and the like are not limited to their strict geometric definition, but include tolerances for machining or human error, reasonable and inconsistent.
As shown in fig. 1, which is a partial view of a helical blade 800, the conventional helical blades 800 are perpendicular to the axis in general, but sometimes, for example, in the special production process, the helical blade 800 is required to be arranged in an inclined manner, and the helical blade 800 arranged in the inclined manner is required, and in the automatic production process, for example, the helical blade 800 is clamped for welding, when clamping the helical blade 800, the conventional clamping device is not adjustable in clamping angle, so that it is difficult to reliably clamp the helical blade 800. The clamping device of the present invention can reliably clamp and fix both the vertical and the inclined helical blades 800, and has the following specific structure.
As shown in fig. 5-7, the clamping device comprises a clamping body 100 and clamping units 200 arranged on the clamping body 100 at intervals along the circumferential direction thereof, wherein the clamping units 200 are provided with clamping ports 210 arranged at equal intervals along a direction a, the clamping ports 210 on each clamping unit 200 are distributed on a spiral line a, the direction a is parallel to the center line of the spiral line a, each clamping port 210 is movably arranged on the clamping body 100, a clamping port adjusting mechanism 300 is further arranged on the clamping body 100, and the clamping port adjusting mechanism 300 adjusts the orientation of the clamping port 210.
When the grip ports 210 are perpendicular to the axis of the helical blade 800, the pitch of each grip port 210 corresponds to the pitch of the helical blade 800. The clamping opening adjusting mechanism 300 of the present invention can adjust the angle of the clamping opening 210 to meet the clamping requirement when the helical blade 800 is arranged in an inclined manner.
As shown in fig. 2, a screw blade 800 is placed on each of the clamping openings 210 of the clamping body 100. The clamping body 100 is rotatably mounted on the rotary mounting rack 920, and the rotary mounting rack 920 is mounted on the traveling device 900. After the spiral blade 800 is placed on the clamping opening 211, the spiral blade 800 and the clamping body 100 are integrally moved, the clamping body 100 is moved by the walking device 900, and the supporting cylinder 910 on the walking device 900 supports the middle part and the end part of the clamping body 100 to be matched with the steel cylinder 600. The steel cylinder 600 is placed on the steel cylinder assembly device 700 which can make the steel cylinder rotate, and the side of the steel cylinder 600 is further provided with a guide device 500 for receiving the other end of the clamping body 100 in a suspension state. When the spiral blade 800 is about to contact the steel cylinder 600, the supporting cylinder 910 at the end is returned to avoid the steel cylinder 600, and when the supporting cylinder at the middle is about to contact the steel cylinder 600, the guiding device 500 is extended into the steel cylinder 600 to support the overhanging end of the clamping body 100, and then the supporting cylinder 910 at the middle is returned. As shown in fig. 2 to 3, the helical blade 800 may be more stabilized by supporting both ends thereof, and the collision of the helical blade 800 with the steel cylinder 600 due to the deformation of the jig may be reduced. Finally, the helical blade 800 and the steel cylinder 600 are coupled together by the welding apparatus 400.
As shown in FIG. 3, the spiral blade 800 and the steel cylinder 600 are spot-welded together along the length direction of the steel cylinder 600 by extending the welding torch 410 of the welding device 400 into the inner cavity of the steel cylinder 600, and the spiral blade 800 and the steel cylinder 600 are connected together by the welding spot 620 shown in FIG. 3, and then are withdrawn. The steel cylinder 600 and the helical blade 800 are rotated by 120 degrees simultaneously, the helical blade 800 and the tubular product are spot-welded together along the tube length direction of the steel cylinder 600, and then the welding gun is returned again, the tubular object and the clamp body are rotated by 120 degrees simultaneously, and the helical blade 800 and the tubular product are spot-welded together along the tube length direction of the tubular product. The 3 rows of welding spots are uniformly welded along the circumferential direction of the steel cylinder 600, so that the steel cylinder 600 and the helical blade 800 are firmly connected together through spot welding.
After the steel cylinder 600 and the helical blade 800 are firmly connected together by spot welding, as shown in fig. 4, the clamping body 100 is withdrawn, the steel cylinder 600 is rotated, the welding gun 410 is moved along the tube length direction of the steel cylinder 600, and the welding path is also helical by adjusting the rotating speed and the moving speed, and is the same as the pitch of the helical blade 800.
Of course, the height of the welding gun can be adjusted, the welding gun is assembled on a manipulator which can rotate and move up and down, and the manipulator is assembled on a suspension rod which can move horizontally, so that the welding gun is suitable for the helical blades 800 with different outer diameters, and various requirements of spot welding and continuous welding are met. The steel cylinder assembling device 700 can also be adjusted up and down to adapt to steel cylinders 600 with different outer diameters.
This welding along the path of the helical blade 800 can provide a very secure connection of the helical blade 800 to the assembled steel cylinder 600. There are significant advantages over the conventional welded helical blade 800. In the conventional method for welding the helical blade 800, the helical blade 800 is divided into a plurality of small helical blades 800, and the small helical blades 800 are spliced together. Obviously, the assembly jig of the present invention can not only significantly improve the welding efficiency of the helical blade 800 but also improve the welding quality. The angle of the clamping opening can be adjusted, so that the clamping device can meet the clamping and fixing requirements of the vertical and inclined spiral blades 800.
