The invention discloses an automotive transmission two-shaft nut / two-shaft bolt tightening assembly which comprises a foundation tightening assembly, a two-shaft bolt tightening sleeve, a tightening connector and a nut rotation-preventing sleeve. The foundation tightening assembly comprises a base with an installing sleeve, a tightening shaft supported to the installing sleeve, a spring located inthe installing sleeve and a flange rotation-preventing limiting base in sliding fit with the installing sleeve; the two-shaft bolt tightening sleeve is selectively and detachably connected with tightening shafts; the tightening connector is selectively and detachably connected with the tightening shafts, is provided with a spline housing and is matched with two-shaft splines; and the nut rotation-preventing sleeve is selectively and detachably connected with the flange rotation-preventing limiting base. According to the automotive transmission two-shaft nut / two-shaft bolt tightening assembly,a traditional tightening machine can tighten a four-wheel drive series transmission two-shaft nut and a longitudinally-arranged rear driven series transmission two-shaft bolt in a compatible manner,the production efficiency is improved while torque is guaranteed, time and labor are saved, and the market quality risks can be effectively avoided.
Description
Technical field [0001] The invention relates to the field of on-line assembly technology of automobile transmissions, in particular to a two-axis nut / two-axis bolt tightening assembly of an automobile transmission. Background technique [0002] With the vigorous development of the automotive industry in recent years, the demand for automotive transmissions is increasing, and their production requirements are getting higher and higher. There are various transmission series on the market, such as longitudinal rear drive series transmission, four-wheel drive series transmission and so on. [0003] The two shafts of the longitudinal rear drive series transmission are all in the form of "flange structure + two shaft bolts". The tightening machine adopts the flange to prevent rotation during the process of tightening the two shaft bolts, and it is enough to tighten the two shaft bolts. [0004] Such as figure 1 , 2 As shown, this component is the sliding table assembly of the tightening m...
