Abstract
The utility model relates to a ball screw moving mechanism. The ball screw moving mechanism comprises a base, wherein bearing pedestals are arranged on the base, a ball screw is arranged on the bearing pedestals, a screw nut seat is arranged on the ball screw, a transition plate is arranged on the screw nut seat, and the transition plate is connected with a moving seat; guide rail sliding blocks are arranged below the two sides of the moving seat; the guide rail sliding blocks are matched with guide rails; the guide rails are arranged on guide rail bases; the guide rail bases are arranged on the two sides of the bearing pedestal and on the base. According to the ball screw moving mechanism provided by the utility model, the moving seat and the transition plate can vertically move slightly and relatively, are always jointed together mutually, and cannot rotate relatively; the structure is low in processing difficulty and can improve the transmission precision effectively.
Description
Technical field
The utility model relates to machine tool field, specifically a kind of ball-screw motion for lathe.
Background technology
: the precision of transmission is high that leading screw rotates freely in the basic demand that utilizes ball-screw-transmission.The transmission of ball-screw is in the past that the screw of ball-screw and motion are rigidly connected, and motion moves along line slideway.This structural requirement leading screw and line slideway in the horizontal direction with vertical direction on all parallel to each other, and the position of leading screw and line slideway interfixes, high to requirement on machining accuracy.Along with the use of ball-screw, between driven motion and the screw of leading screw, add adjusting pad, although this structure has slightly reduced machining accuracy, but still require ball-screw and line slideway in the horizontal direction with vertical direction on all parallel to each other, requirement on machining accuracy is still very high, cause processing cost very high, and ball-screw and line slideway is not parallel causes the life-span of ball-screw shorter.
Utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, and ball-screw motion stably moves.
The utility model solves its technical problem by the following technical solutions.
A kind of ball-screw motion, comprises base, and described base top is provided with bearing block, and described bearing block is provided with ball-screw, and described ball-screw is provided with nut seat, and described nut seat is provided with rebound, and described rebound connects kinematic nest; Described kinematic nest down either side is provided with guide rail slide block, and described guide rail slide block and guide rail match, and described guide rail is located on track base, and described track base is located at base top chock both sides.
Described kinematic nest is provided with connecting plate, and described connecting plate top is provided with platform, and both sides, described connecting plate below are provided with slide block Connection Block, and described slide block Connection Block is connected with guide rail slide block.
Described rebound middle part is provided with installing hole, and described nut seat is sleeved in installing hole.
Described connecting plate is provided with locating hole, and described rebound is provided with breach, between the locating hole on described breach and connecting plate, is provided with alignment pin.
A kind of ball-screw motion of the present utility model, fine motion up and down between kinematic nest and rebound, but fit together all the time each other, and can not relatively rotate, this structure difficulty of processing is low, and can effectively improve transmission accuracy.
