Embodiment

[0011] figure 1 In the shown embodiment, the driving gear 1 meshes with eight driven gears 2; one end of the main shaft 3 is matched with the positioning hole in the center of the equipped turntable, and four sinking grooves are processed on the driving gear 1, and the driving gear 1 is connected to Connect with the positioning T-slot of the turntable. Driving gear 1 meshes with eight driven gears 2. The driven gear 2 is assembled with the three-jaw chuck 5 through the station shaft 4 . The station shaft 4 is evenly installed on eight station holes uniformly distributed on a circular mounting plate 7 through a group of back-to-back thrust bearings 6, and the main shaft 3 passes through the center of the mounting plate 7. On the outer edge of the mounting plate 7, there are eight one-way stop steps 8 at the position where the station axis 4 intersects the radius of the circular mounting plate.

Abstract

The invention relates to an external power source multi-station welding fixture used in gas shielded welding, laser welding and vacuum electron beam welding. In the present invention, without adding a new electromechanical control system, the ordinary welding turntable is used as the power source, and the power and control system is not provided by itself. Welding process. The design of the stop step and the stop rod realizes the conversion of the two modes of station conversion and part rotation. With the turntable, it can meet the welding requirements of the rotary weld at any angle position from horizontal to 90°. When welding, especially precision welding such as laser welding and electron beam welding, the standby time caused by assembly is reduced and work efficiency is improved.

Description

technical field [0001] The invention relates to an external power source multi-station welding fixture used in gas shielded welding, laser welding and vacuum electron beam welding. Background technique [0002] At present, there are many multi-station fixtures used in welding. According to their control methods, they can be divided into automatic and manual. Among them, the automatic fixture has its own motor, which uses transmission mechanisms such as gears or chains to decompose the movement and complete the parts' own actions and operations. Transformation of workstations. The welding fixture with its own power has complete functions and flexible control, but the cost is relatively high; at the same time, for vacuum electron beam welding machines, due to the barrier of the vacuum chamber, it is relatively complicated to increase the control system technology. The original welding fixtures of vacuum electron beam welding machines are mostly manual fixtures. For manual fix...
