Description
Technical field
The utility model relates to field of automobile, more particularly, relates to a kind of rear axle housing body and spindle nose welding jigs and fixtures.
Background technology
At present, the rear axle housing body of automobile axle and the friction welding production technology that generally adopts the advanced person being connected of spindle nose, what generally adopt both at home and abroad is double-head automobile back axle friction welding technological, and production efficiency is high, and welding quality is good.
As shown in Figure 1, the friction welding mode is that spindle nose 16 is clamped on the rotary main shaft 11 at lathe two ends, rear axle housing body 17 is clamped in the middle part of lathe, adopts weld jig that the stage casing of spindle nose 16 is clamped, and the leading portion of spindle nose 16 and rear axle housing body 17 carry out friction welding.After the friction welding, require the postwelding axiality of spindle nose 16 at two ends less than 0.5mm, can satisfy direct applied requirement after the automobile industry friction welding, just can reach instructions for use otherwise will increase the aligning operation.
As shown in Figure 1, existing weld jig mainly comprises: be used for the fixedly positioning mandril 12 of the back segment of spindle nose 16; The claw 15 that is used for the stage casing of clamping spindle nose 16; Be sheathed on claw 15 outsides, and can drive the radially mobile clamping cone sleeve 14 of claw 15; Be sheathed on the outside of clamping cone sleeve 14, and drive the clamping piston 13 that clamping cone sleeve 14 moves to the direction away from claw 15 vertically, clamping piston 13 matches with the inner chamber of rotary main shaft 11, and clamping piston 13 can only move vertically.When needing the dismounting spindle nose, effect clamping piston 13 makes it drive clamping cone sleeve 14 and moves to the direction away from claw 15 vertically, so that claw 15 can move along the radial, namely claw 15 no longer clamps spindle nose 16, can take off spindle nose 16.The installation process of spindle nose 16 is opposite with said process, and this paper repeats no more.
But, existing weld jig clamps the stage casing of spindle nose 16, the leading portion of spindle nose 16 stretches in weld jig outward, because friction welding is with the leading portion of spindle nose 16 and rear axle housing body 17 welding, so that the rigidity of spindle nose 16 after being held is lower, more easily cause spindle nose 16 vibration-generating when welding, easily to be positioned at the axiality of spindle nose 16 at rear axle housing body 17 two ends after the friction welding larger, can not satisfy the requirement of direct use, thereby increased the situation that the aligning operation increases, finally reduced the production efficiency of automobile axle.
In sum, being positioned at the axiality of the spindle nose at rear axle housing body two ends after how reducing to weld, and then reducing the increase of aligning operation, improve the production efficiency of automobile axle, is present those skilled in the art's problem demanding prompt solution.
