The present invention also comprises following additional technical feature:
Described planker square groove bottom surface is provided with the screw of two rows perpendicular to this bottom surface along the planker direct of travel, the lower plane at the place, trapezoidal long limit on described the inserting is provided with perpendicular to this plane and the step through-hole corresponding with described screw, pass described step through-hole with screw and be screwed into described screw, described inserting fixedlyed connected with described planker respectively.
Side, described planker both sides is respectively arranged with the screw of a row perpendicular to this side along the planker direct of travel, be screwed into this screw with holding screw and be resisted against described side of inserting, can regulate the distance of inserting with respect to described planker square groove side, when described dovetail groove and dovetail effect of attrition planker running precision, adjusting is inserted and is proofreaied and correct described dovetail groove with respect to the distance of described planker square groove side, with assurance planker running precision, thus the machining accuracy of assurance lathe.
The upper rail face upper edge planker direct of travel at place, the trapezoidal long limit of described guide rail is provided with the step through-hole of a row perpendicular to this plane, and described track base is provided with corresponding with it screw, with screw described guide rail is fixedlyed connected with track base.
The present invention can reach following beneficial effect: adopt split type oat tail groove structure and dovetail structure, reduced difficulty of processing, simply the disassembling, assembling and replacing easy-abrasion part has reduced material cost again, has guaranteed the running precision of machine tool feed planker, has ensured the workpiece machining accuracy of lathe.
