Detailed Description

The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.

Please combine fig. 1 to 4 to show, the utility model discloses pipe fitting flange welded auto-lock frock that embodiment relates to includes base 1, drive arrangement 2, rotates chuck 3 and self-locking mechanism 4, and base 1 is used for fixed drive arrangement 2, and drive arrangement 2 adopts gear motor in this embodiment, and one rotation chuck 3 is connected in gear motor's pivot, rotates chuck 3 rotation through the gear motor drive. The speed reducing motor is arranged below the base 1, and the rotary chuck 3 extends out of a top plate of the base 1 and is used for clamping and fixing a flange 5 workpiece to be welded. The rotating chuck 3 is a metal cylinder, and a radial through groove 301 is formed at the top of the rotating chuck 3 to form a left clamping part 302 and a right clamping part 302. The top ends of the left and right clamping portions 302 are provided with axial positioning cavities 303, and the axial positioning cavities 303 are used for accommodating the flanges 5. When the flange 5 is clamped between the left and right clamping portions 302 of the rotating chuck 3, the flange 5 causes the left and right clamping portions 302 to be deformed outwardly to a certain extent, and the flange 5 is clamped by the restoring elastic force of the left and right clamping portions 302. The bottom of the flange 5 is in contact with the bottom of the axial positioning cavity 303, the depth of the axial positioning cavity 303 is smaller than the thickness of the flange 5 so as to facilitate the placement and the removal of the flange 5, and the top surface of the flange 5 after being positioned in the axial positioning cavity 303 protrudes out of the top surface of the rotating chuck 3 so as to facilitate the welding operation of the welding gun head.

An upright post 101 is fixed on one side of the base 1, the cross section of the upright post 101 is rectangular, a plurality of fixing hole positions 102 are arranged on the upright post 101, and the self-locking mechanism 4 is fixedly connected with the upright post 101 through the fixing hole positions 102. Two self-locking mechanisms 4 are typically provided to position the pipe 6. As further shown in fig. 5 to 7, the self-locking mechanism 4 mainly comprises three components, which are a positioning body 401, a positioning lock 402 and a control wrench 403, wherein the tail of the positioning body 401 is provided with a vertical slot 4011, the vertical slot 4011 is matched with the shape of the upright post 101, the upright post 101 is clamped in the vertical slot 4011, and then the upright post 101 is screwed into the fixing hole 102 through the positioning body 401 by using a screw to fix the positioning body 401. A side opening groove 4012 is formed in the head of the positioning body 401, the side opening groove 4012 is provided with a semicircular arc groove bottom, the diameter of the semicircular arc, namely the groove width, is slightly larger than the diameter of the pipe fitting 6 to be processed, and a horn shape is formed in a groove opening of the side opening groove 4012 so that the pipe fitting 6 can laterally enter and exit the side opening groove 4012. After the positioning body 401 is fixed on the column 101, the bottom of the side opening groove 4012 is located right above the rotary chuck 3.

The positioning lock catch 402 and the control wrench 403 form a movable part of the self-locking mechanism 4, wherein the positioning lock catch 402 is hinged to the positioning body 401, a transverse groove 4021 is formed in the positioning lock catch 402 in the thickness direction, and the head of the positioning body 401 is located in the transverse groove 4021. The hinge shafts of the positioning body 401 and the positioning lock 402 are located on the side of the side opening slot 4012 close to the head of the positioning body 401. The side of the positioning lock 402 facing the tail of the positioning body 401 is provided with a protrusion 4022, when the positioning lock 402 rotates to make the head of the positioning body 401 contact with the bottom of the transverse groove 4021, the protrusion 4022 is located at the side opening groove 4012, so that the bottom of the semicircular arc groove of the side opening groove 4012 is matched with the protrusion 4022 to form a limiting area with an opening width smaller than the diameter of the pipe fitting 6, and the pipe fitting 6 cannot be laterally separated from the side opening groove 4012, as shown in fig. 5. The control wrench 403 is L-shaped, the short arm of the control wrench 403 is hinged to the positioning latch 402, and the hinge shaft of the positioning latch 402 and the hinge shaft of the positioning body 401 are located on the side away from the protrusion 4022. A cam 4031 is connected to the hinge shaft of the control wrench 403 and the positioning lock 402. The positioning body 401 is provided with a locking groove 4013 at a position corresponding to the hinge shaft of the control wrench 403 and the positioning locker 402, and the cam 4031 is positioned in the locking groove 4013. The long arm of the control wrench 403 is in a first position (as shown in fig. 4 and 5) proximate to the locking buckle 402, and the long arm of the control wrench 403 is in a second position (as shown in fig. 6 and 7) away from the locking buckle 402. When the control wrench is in the first position, the cam 4031 abuts against the groove bottom of the locking groove 4013, the protrusion 4022 of the positioning lock 402 is located at the position of the side opening groove 4012, so as to limit the position of the pipe fitting 6, and due to the limitation of the cam 4031, the positioning lock 402 is difficult to push the control wrench 403 to rotate, and the notch of the side opening groove 4012 cannot be easily opened, so that the pipe fitting 6 is separated. When the operator rotates the control wrench 403 to the second position, the cam 4031 has a gap in the locking slot 4013, and the positioning lock 402 can rotate to a certain extent, so that the protrusion 4022 is away from the side opening slot 4012, thereby facilitating the removal of the pipe fitting 6. The auto-lock frock of pipe fitting flange welded of this embodiment passes through operation control spanner 403, can conveniently go up unloading operation on pipe fitting 6, fixes a position and does not hinder its rotation to pipe fitting 6 simultaneously in welding process, has guaranteed the straightness that hangs down with the flange.
