Embodiment

[0011] In the embodiment shown in Figure 1, 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 the driving gear 1 is processed with four sinking grooves, and the driving gear is connected by four bolts. Gear 1 is connected 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.

[0012] In the embodiment shown in Figure 2, that is, in...

Abstract

The invention relates to a multi-station welding fixture with external power supply used in the gas shielded weld, the laser weld, and the vacuum election beam welding. Without extra electromechanical control system, the invention adopts common welding revolving table as power supply and is not provided with momentum and control system, so the invention utilizes the revolving table momentum to drive a plurality of components to spin and transform work stations, and realizes automatic multi-work-station welding process. The design of the stopping step and the locking handle realizes the transform between the work station transformation and the component spin and matched revolving table, which can satisfy the welding requirements of gyrating welding joint at any angle form 0 to 90 degrees. The invention has the advantages that: when welding, in particular to precision welding such as the laser welding and the election beam welding, the standby time due to assembly is decreased, 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...
