Abstract
The utility model discloses a worktable conveying device of a planer type milling machine. The worktable conveying device comprises a milling machine body, a workable and a screw mechanism, wherein the worktable is arranged above the milling machine body; the screw mechanism comprises a screw, a nut group, a first fixed seat and a second fixed seat, wherein the first fixed seat is arranged below the worktable, the second fixings seat is arranged above the milling machine body, the nut group is arranged inside the first fixings seat, and the screw passes through the nut group inside the first fixings seat and the second fixed seat. By adopting screw transmission, the worktable conveying device is small in friction resistance and high in precision; moreover, a clearance between the screw and each nut is adjustable, so when the clearance is formed between the screw and the nut, a clearance adjusting screw can be adjusted to eliminate the clearance between the screw and the nut, the feeding precision of a work piece can be guaranteed and the machining precision can be improved, so the rate of good products is increased.
Description
Technical field
The utility model relates to machine tool field, refers to especially a kind of workbench transmitting device of planer-type milling machine.
Background technology
Traditional planer-type milling machine is by wheel and rack transmission, realize the movement of workbench, but it is large that the drive gap working long hours between backgear and tooth bar becomes, deterioration in accuracy, easily cause workbench to occur creeping phenomenon, affect the accurate location of workbench, thereby the machining accuracy of workpiece cannot be guaranteed, the percent defective of product increases.
Utility model content
The workbench transmitting device that the utility model proposes a kind of planer-type milling machine, has solved the above-mentioned problems in the prior art.
The technical solution of the utility model is achieved in that
A kind of workbench transmitting device of planer-type milling machine, comprise lathe bed, workbench and screw mechanism, described workbench is arranged on lathe bed top, described screw mechanism comprises leading screw, nut group, the first holder and the second holder, described the first holder is arranged on workbench below, described the second holder is arranged on lathe bed top, and described nut group is arranged in the first holder, and described leading screw is through nut group and the second holder in the first holder.
Preferably, described nut group comprises the first nut and the second nut, described the first nut and the second nut are disposed in the first holder, and described the first nut is by adjusting gap screw to be arranged in the first holder, and described the second nut is fixed in the first holder by hold-down screw.
Preferably, on described the first holder, be also provided with locating piece, described locating piece one end is provided with tooth portion, and described the first nut outer circumference is provided with tooth portion, and the position of the first nut is engaged to fix by the tooth portion of described locating piece and the tooth portion of the first nut.
The beneficial effects of the utility model are:
This workbench transmitting device adopts lead screw transmission, frictional resistance is little, precision is high, and the gap between leading screw and nut is adjustable, in the time there is gap between leading screw and nut, can adjust gap screw to eliminate the gap between leading screw and nut by adjustment, can ensure the feed accuracy of workpiece, improve machining accuracy, and then improve the yields of product.
