Utility model content
The utility model is intended to solve above-mentioned technical problem to a certain extent.
In view of this, the present invention provides a kind of gantry circular saw bench, the guiding performance of the sawing machine guide rail is good, runs smoothly And suffered torque is small.
A kind of gantry circular saw bench comprising crossbeam, transmission case and spindle box, it is characterised in that: the crossbeam lower section is two Guide rail, the transmission case lower vertical connect the spindle box, and the spindle box is located at immediately below the guide rail, and with it is described It is connected between crossbeam with ball screw assembly, the ball-screw of the ball screw assembly, is installed under the crossbeam between two guide rails Surface, the spindle box connect the feed screw nut of the ball screw assembly, and the two sides convex upper portion of the spindle box respectively connects one Block pressur plate, plane cooperates on the pressing plate and the guide rail, the pressing plate and the spindle box coat the guide rail and with it is described Guide rail is slidably connected, and the spindle box is straight along the guide rail together with the transmission case under the power drive of the ball screw assembly, Line sliding.
Further, the transmission case is located at the crossbeam side, and the same upper lateral part of the crossbeam is equipped with L v notch v, L v notch v bottom surface is provided with rolling guide, and the transmission upper box part is connect with the sliding block of the rolling guide.
Further, the crossbeam bottom surface is provided with the groove body of indent, and the ball-screw is mounted in the groove body.
Further, the spindle box is in U-shape.
Further, the beam sides are provided with groove, and the pressing plate is located in the groove.
Further, the groove both ends are in step-like, and the step surface lower part is respectively connect with a support frame.
Further, the ball-screw end connects shaft coupling, the shaft coupling and the servo for being fixed on crossbeam end face Motor is connected.
The utility model has the technical effect that crossbeam lower part is equipped with two guide rails, and spindle box is located at the underface of guide rail And connect between crossbeam with ball screw assembly, two upper lateral part of spindle box is each provided with a block pressur plate, pressing plate and spindle box and guide rail Main guide rail pair is formed, was both oriented to, while being also subjected to the small part weight of spindle box and transmission case, cross rail top and transmission case Between be equipped with rolling guide, bear spindle box and transmission case most of weight, effectively mitigate main guide rail pair load and add Moment of flexure torque reduces abrasion, while also playing the role of auxiliary guiding, becomes secondary guide rail.Main guide rail pair is from spindle box and to sawing Steel plate distance is close, and guiding rigidity and precision are good, and the torque and cutting force of receiving are relatively small and balanced, wears small, high reliablity. Spindle box runs smoothly between guide rail and steel plate, excellent cutting performance.
