The utility model content
The utility model technical issues that need to address provide the stand column device of a kind of pair of transmission, it mainly is to solve existing in prior technology one vertical driving screw device only is set in column, nationality drives saddle upper and lower displacement action in column by the rotation of driving screw device, yet because the driving screw device only is provided with one group, and the center of saddle has been equiped with the main shaft slide, therefore the driving screw device drives the side that the strength of saddle is partial to saddle, cause the strength imbalance that drives saddle, make the upper and lower action technical problem of instability etc. comparatively of saddle.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The stand column device of of the present utility model pair of transmission, comprise base, base is provided with column, the top that it is characterized in that described column is provided with two transmission devices, two transmission devices respectively connect and drive a driving screw, two driving screws are located at the both sides of column respectively, be provided with saddle between two driving screws, the main shaft slide is housed in the saddle, the both sides of saddle are connected with the nut that matches with driving screw, the both sides of column respectively are connected with an one slide rail, and the saddle both sides are slidingly connected on the slide rail by slide block.The symmetrical respectively and arranged on left and right sides that is installed in this column of two transmission devices system, transmission device can be a servo motor, each servo motor system is incorporated into the top of column, and each guide screw leverage is located at the and arranged on left and right sides of saddle with vertical kenel, and the top of each driving screw is connected in each servo motor.Line between two nuts of saddle system is by the geometric center of this saddle, and by this, two transmission devices are balance and stably drive the saddle action positively.
As preferably, described column is vertically disposed framework, and saddle places in the framework, and the both sides of saddle front respectively are connected with a step, and slide block is installed on the step.Column is vertically disposed framework and has an end face and a front that column forms a saddle installing department in inside.
As preferably, be connected with two base slide rails on the described base, the column bottom is slidingly connected on the base slide rail by the base slide block, and the column bottom also is connected with the drive unit that it is moved horizontally.Can regulate column position in the horizontal direction like this.
As preferably, the both sides of described column front end respectively are connected with the optics chi that can detect upper and lower position, saddle both sides, and the optics chi is located at the outside of slide rail.Two optics chis can be detected the position and the feedback of saddle and control each servo motor, make the precision of saddle action more promote.
As preferably, described saddle inner hollow is connected with main shaft slide installing department in it, and the main shaft slide is contained on the main shaft slide installing department.
Therefore, the utlity model has upper and lower the moving of actuator drives saddle of column both sides, compared to existing single design that drives, driving force on average is not partial to a side, can make the saddle action comparatively stablize certain characteristics to drive the upper and lower displacement of saddle than stable manner; The utility model also has and the optics chi is set in order to upper and lower shift position, detecting saddle both sides and feed back to the servo motor of transmission device, make the upper and lower shift position of saddle both sides can reach consistent really, significantly increase the precision of saddle action, characteristics such as simple and reasonable for structure.
