Abstract
The utility model discloses a spindle ram-combined guide rail unit for numerically controlled milling planers, which comprises a crossbeam moving base, a headstock is arranged on the crossbeam moving base, linear sliders and plastic-coated adjusting gibs are mounted in the headstock, the spindle ram-combined guide rail unit also comprises a spindle ram, a spindle is mounted in the spindle ram, linear slide rail pairs and quenched slide rail pairs are mounted on the outer surface of the spindle ram, and moreover, the spindle ram is mounted in the headstock, and is slidably connected with the headstock through the slide rails. The spindle ram-combined guide rail unit has the advantages of high rigidity, high precision, high moving speed and high production efficiency.
Description
Technical field
The utility model relates to plant equipment and makes the field, particularly a kind of CNC planer type milling machine Chief axis composite guide rails unit.
Background technology
The CNC planer type milling machine application popularization of present industrial manufacturing enterprise, more the Chief axis unit adopts guide pass to harden and processes and the secondary combination of plastic-sticking guiding rail, the manufacturing enterprise that also has replaces ram gib with linear slide rail, to sum up two schemes has certain drawback, is analyzed as follows:
1. laminating hard rail Chief axis unit hardens, coefficient of friction is large, antitorque rigidity is good, but process velocity can be restricted when practical application for lathe, the positioning accuracy of Z axis can be along with the variations in temperature of ram unit and is changed, make control system can't compensate solution, the loss of guide pass is larger, and the geometric accuracy of lathe is difficult to keep for a long time (Z axis is with respect to X-axis, Z axis 90 ° of perpendicularity with respect to Y-axis and A axle line of motion).The user needs often to adjust the geometric accuracy of Chief axis, thereby has reduced service efficiency and machining accuracy in use, has improved user's production cost.
2. the Chief axis unit of linear slide rail, overcome geometric accuracy and kept poor problem, improved process velocity, reduced thermal change type coefficient, but the use age due to linear slide rail on precision machine tool is shorter, many manufactories copy using, do not understand the characteristic of linear slide rail, all to buy the makers' standard component of linear slide rail to use, because the anti-twist requirement of precision machine tool when the practical application do not understood by linear slide rail manufacturer, so linear slide rail that often provides, only embodied emphatically load, do not consider that lathe is adding the reverse anti-twist problem in man-hour, so linear slide rail anti-twist rigidity when practical application is very poor.
Summary of the invention
The purpose of this utility model is in order to address the above problem, and has designed a kind of CNC planer type milling machine Chief axis composite guide rails unit.
Realize that the above-mentioned purpose the technical solution of the utility model is, a kind of CNC planer type milling machine Chief axis composite guide rails unit, comprise the cross beam movement seat, the cross beam movement seat is provided with headstock, linear slide block and laminating adjustment clamp bar are installed in headstock, also comprise Chief axis, main shaft is installed in Chief axis, linear slide rail pair and the rail plate pair of hardening are installed, and Chief axis is arranged in head and forms slidably guide rail connected mode with headstock on the outer surface of Chief axis.
Described slidably guide rail connected mode is linear slide rail is secondary and the rail plate pair of hardening is mated in headstock pack into linear slide block and the formed connected mode of laminating adjustment clamp bar on Chief axis.
Described laminating adjustment clamp bar is and the secondary strip structure of matching of the rail plate that hardens.
The CNC planer type milling machine Chief axis composite guide rails unit that utilizes the technical solution of the utility model to make, the combining structure of employing linear slide rail and the rail plate pair of hardening makes Chief axis have fabulous anti-twist rigidity and the flexibility of operation fast.Simple to operate, need not frequent adjusting, high efficiency has been saved production cost.
Description of drawings
Fig. 1 is the structural representation of CNC planer type milling machine Chief axis composite guide rails described in the utility model unit;
In figure, 1, the cross beam movement seat; 2, headstock; 3, linear slide block; 4, laminating adjustment clamp bar; 5, Chief axis; 6, main shaft; 7, linear slide rail is secondary; 8, the rail plate pair of hardening.
The specific embodiment
below in conjunction with accompanying drawing, the utility model is specifically described, it is the structural representation of CNC planer type milling machine Chief axis composite guide rails described in the utility model unit as Fig. 1, as shown in the figure, a kind of CNC planer type milling machine Chief axis composite guide rails unit, comprise cross beam movement seat 1, the cross beam movement seat is provided with headstock 2, linear slide block 3 is installed in headstock, with laminating adjustment clamp bar 4, also comprise Chief axis 5, main shaft 6 is installed in Chief axis, linear slide rail pair 7 is installed on the outer surface of Chief axis, with the rail plate pair 8 of hardening, and Chief axis is arranged in head and forms slidably guide rail connected mode with headstock.Wherein, described slidably guide rail connected mode is linear slide rail is secondary and the rail plate pair of hardening is mated in headstock pack into linear slide block and the formed connected mode of laminating adjustment clamp bar on Chief axis; Described laminating adjustment clamp bar is and the secondary strip structure of matching of the rail plate that hardens.
The characteristics of the technical program are that Chief axis adopts linear slide rail and hardens rail plate pair and linear slide block and the combination of laminating adjustment clamp bar, take linear slide rail as the main movement guide rail, guaranteed that well Z axis is with respect to X-axis, Z axis 90 ° of perpendicularity with respect to Y-axis and A axle line of motion, the user need not often adjust the geometric accuracy of Chief axis in use, has improved service precision and the service efficiency of lathe.As the synkinesia guide rail, increase the coefficient of friction of Chief axis unit with harden rail plate pair and laminating adjustment clamp bar, improved the anti-twist rigidity of lathe when heavy cut, make the working (machining) efficiency of lathe and machining accuracy more guaranteed.The rail plate pair of hardening is adjusted pretension with holding strip type, adjust to keep at any time the anti-twist rigidity of Chief axis unit, is aided with amesdial during adjustment and follows the tracks of, and is efficient and convenient, and do not affect Z axis with respect to X-axis, Z axis 90 ° of perpendicularity with respect to Y-axis and A axle line of motion.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; some changes that those skilled in the art may make some part have wherein all embodied principle of the present utility model, within belonging to protection domain of the present utility model.
