Have above-mentioned deficiency in prior art in order to overcome, the utility model provides a kind of guide rail mechanism of simple in structure, machining accuracy is high, bite is large, working (machining) efficiency is high lathe.
the technical scheme in the invention for solving the technical problem is: a kind of guide rail mechanism of lathe, comprise two rail bracketses laterally being located on lathe bed and being arranged in parallel, be equipped with cross slide way on the described rail brackets of each root, the top of these two cross slide waies is across being provided with lower planker, the both sides of the lower end of this time planker are installed with transverse slider on the position corresponding with described two cross slide waies, this transverse slider is slidedly arranged on described cross slide way, the inboard symmetry of the upper end of two described rail bracketses is concaved with the located lateral shoulder block, the middle part of the lower end of described lower planker convexes with the located lateral projection, the both sides of this located lateral projection are sliding fitting on described located lateral shoulder block respectively.
further, the upper end of described lower planker be provided with two be arranged in parallel and with perpendicular two longitudinal rails of described cross slide way, the top of these two longitudinal rails is across being provided with upper planker, the both sides of lower end that should upper planker are installed with longitudinal sliding block on the position corresponding with described two longitudinal rails, this longitudinal sliding block is slidedly arranged on described longitudinal rail, the both sides of the lower end of described upper planker are extended with the location division downwards, the inboard symmetry of this two location division convexes with the longitudinal register shoulder block, the bilateral symmetry of the upper end of described lower planker is concaved with the longitudinal register step, the both sides of this longitudinal register step are sliding fitting on described longitudinal register shoulder block respectively.
occupation mode of the present utility model is identical with the occupation mode of guide rail mechanism of the prior art, when processing work, upper planker vertically moves along lower planker, the longitudinal sliding block of namely going up on planker vertically moves along the longitudinal rail on lower planker, go up simultaneously longitudinal register shoulder block on planker along the longitudinal register step slippage on lower planker, lower planker is along the rail brackets transverse shifting, namely descend transverse slider on planker along the cross slide way transverse shifting on rail brackets, located lateral projection on same planker at present is along the located lateral shoulder block slippage on rail brackets, thereby driving workpiece or knife rest carries out transverse shifting or vertically moves, but because the lower end at lower planker is provided with the located lateral projection, be provided with the located lateral shoulder block slippery with the located lateral projection on rail brackets, be provided with the longitudinal register step in the upper end of lower planker, be provided with the longitudinal register shoulder block slippery with the longitudinal register step on upper planker, even planker or lower planker on colliding in process, perhaps need to adjust workpiece or knife rest on upper planker during the position, planker is rotated relative to lower planker, perhaps descend planker to rotate relative to rail brackets, locate more reliable, machining accuracy is higher.Simultaneously, between upper planker and lower planker, have location structure between lower planker and rail brackets, thereby the cutting force that makes planker and lower planker to bear is larger, and bite can reach 4mm, and not only working (machining) efficiency is high, and product rejection rate is low.
The beneficial effects of the utility model are: adopt said structure, not only the location is more reliable, and machining accuracy is higher, and working (machining) efficiency is high, and product rejection rate is low.
