Comprehensive processing machine is on the base of slide has a pillar, in the post to go, the sliding displacement type installed a saddle, the saddle is along the direction before and after extension of elongated body, before and after the slide in the saddle with can and the spindle slide, to create an spindle, the spindle slide in the post set a vertical guide screw device, by rotating lead screw device driver of the side of the saddle, the saddle in the post for the displacement of upper and lower movement.
However, because of the lead screw device drivers on the side of the saddle, the action or stops, the saddle end because of inertia, after will be relative to the saddle of the side of upper and lower swings, leading to the process of movement of the saddle movement is not smooth, and reduces the machining accuracy, so in the process of solving saddle action generated by the vibration on the comprehensive machine for the design of a large project.
Saddle side shock absorber
Including column 1, column formed within set and for vertical column in a saddle furnish 2, saddle furnish division is equipped with three sliding saddle up and down, the pillar is equipped with two servo motors 4 above, each servo motor is connected with a lead screw 5, lead screw nut through 6 connection saddle, both sides of the pillar with slide 7, saddle shoulder 8 sets slider on 9, slider sliding connection on the slide,
The column is also equipped with auxiliary slide track 10, which is connected with auxiliary slide block 11, which is connected with the damping slide block 12, and the damping slide block block is connected with the saddle. The slide rail is located on both sides of the column, and the auxiliary slide rail is fixed vertically on one side of the left and right sides of the column. As shown in FIG. 4, the damping slider seat consists of a slider joint 13 connected with the auxiliary slider 11. The slider joint is the same as the 14 connecting the neck to the base 15, and the base is fixed on the saddle. The base is a rectangular plate body with an inner and outer sides, and its inner surface is attached and spirally locked on the side of the saddle. The base outside is vertically extended outwards and the neck can be scratched 14, the neck can be scratched is a rectangular plate set vertically, and the slider joint is a rectangular block body.
When in use, to make the saddle 3 move up and down, each servo motor 4 turns each guide screw 5 to drive each nut 6 to move up and down. By means of this, the saddle moves up and down along each sliding track 7 and auxiliary sliding track 10 by the sliding block 9 and auxiliary sliding block 11.
Since the front and back of the saddle are combined with slide block 9 and auxiliary slide block 11 respectively and slide track 7 and auxiliary slide track 10 on the front and back of pillar 1, the design of this kind of front and rear guidance enables the saddle to slide in a relatively balanced way, providing smooth and stable effect of up and down movement. Moreover, the vibration generated by inertia at the rear end can be reduced through the transmission of the flexural neck when the saddle moves or stops, as a result of the formation of a flexible flexural neck 14 in the damping slider seat 12, making the saddle slide more stable.
