Elevator transmission frame welding and positioning device and welding method thereof

Abstract

The invention relates to an elevator transmission frame welding and positioning device. The elevator transmission frame welding and positioning device is characterized by comprising a welding machine base provided with a left side beam and a right side beam, the left side beam and the right side beam are parallel with each other, the upper surface of the left side beam and the upper surface of the right side beam are respectively and fixedly connected with a bottom plate, the bottom plates are located on the same plane, two cross rods are transversely arranged between the left side beam and the right side beam, the two end faces of each cross rod are respectively provided with threaded holes matched with bolt holes in fixed frames on the two sides of a transmission frame, the back side portion of each bottom plate is provided with an L-shaped supporting plate used for positioning back angle iron on the back side of the transmission frame, the front side portion of each bottom plate is provided with vertical fixing plates matched with the inner side faces of lugs on the front side of the transmission frame, the inner side of each fixing plate is fixedly connected with positioning blocks extending out of the back side face of a connecting plate, and the positioning blocks are perpendicular to the back side face of the connecting plate and are used for positioning front angle iron on the front side of the transmission frame. The invention further relates to a corresponding elevator transmission frame welding method.

Description

technical field [0001] The invention relates to a welding positioning device, in particular to a welding positioning device for an elevator drive frame. Background technique [0002] The welding of the existing construction elevator transmission frame is judged by the welder by the naked eye. Even experienced welders will have visual errors, so that the positioning accuracy of each component on the elevator transmission frame obtained by welding is not perfect. However, the welding accuracy of the elevator transmission frame directly affects the normal and safe operation of the construction elevator. The deviation of the welding positioning accuracy makes the operation of the construction elevator a great safety hazard. Contents of the invention [0003] In view of this, the object of the present invention is to provide a welding positioning device for an elevator drive frame that is reliable in positioning and can effectively improve welding efficiency. [0004] The pres...
