Problems solved by technology
[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.

Description
technical field [0001] The invention relates to a welding positioning device, in particular to a welding positioning device for an elevator transmission 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.
