Existing integrated processor system 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, in the saddle set along the direction before and after wearing a spindle slide, the spindle slide with a spindle, and between the bottom and the saddle is equipped with a set of slide, the slide block group, whereby the spindle slide in front and back and the shape of the sliding set in the saddle.
However, due to the main shaft at the bottom of the slide just to have guidance before and after displacement between the saddle and the slide, the slide block group, thus makes when the spindle slide forward out of the saddle, easy to cause the front blue, and because fewer limitations in other direction of degrees of freedom, making the process of movement of the saddle prone to offset or the condition of the vibration, not smooth, reduce the machining precision.
Spindle slide seat stable sliding device
Including 1 saddle ontology, the saddle of the ontology with internal spindle slide body 2, 3, line on the slide body is equipped with the main saddle ontology through the spindle drive connection slide ontology, drive included in saddle ontology back-end is equipped with four servo motor, servo motor connection guide screw 5, the guide screw nut through 6 connection shaft slide ontology, guide screw end with the bearing seat 14; The saddle body forms a main shaft sliding seat mounting part 7 in the middle.
The mounting part of the spindle slide seat has holes in the front, and a left side wall (8) and a right side wall (9) are formed on the left and right sides of the inner wall of the spindle slide seat. The main shaft sliding seat body is a rod body extending along the front and back direction and is arranged at the installation part of the main shaft sliding seat.
There is one slide rail 13 on the left side 11 and the upper and lower positions of the right side 12 of the main shaft slide seat body, and each slide rail is arranged at each slide block 10. The slider is set in the way of arrangement before and after spacing respectively, and the slider system of each left and right spacing is set symmetrically, that is, there are 8 slider in total.
Servo motor 4 drives the guide screw 5 to rotate, and the main shaft sliding seat body 2 can move forward and backward within the saddle body 1. Due to the effect of 8 sliding blocks 10 and 4 sliding rails 13, the main shaft sliding seat body moves stably, which can improve the machining accuracy.
