Abstract
The utility model discloses a Z-axis transmission mechanism, which comprises a longitudinal guide-way seat and a Z axis, and is characterized in that the guide-way seat and the Z axis are provided with a straight-line guide-way pair and a ball-screw nut pair, wherein a straight-line guide way of the straight-line guide-way pair is installed on the guide-way seat, and a sliding block is installed on the Z axis; and a ball screw of the ball-screw nut pair is installed on the guide-way seat, and a nut is installed on the Z axis. The Z-axis transmission mechanism has the advantages of high sensitivity and high precision.
Description
Technical field
The utility model relates to a kind of Z shaft transmission that is used for lathe, particularly to-and-fro wire-travelling type electric spark linear cutting machine.
Background technology
At present in the to-and-fro wire-travelling type electric spark linear cutting machine of each manufacturers produce, Z shaft transmission commonly used comprises longitudinally track base, Z axle, is arranged on rail plate pair and T shape screw pair on track base and the Z axle, and combination transmission secondary by rail plate and T shape screw pair shows the lifting of Z axle; But because two kinematic pairs are sliding friction, creeping phenomenon is serious, has reduced the sensitivity and the precision of transmission mechanism.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of Z shaft transmission is provided, and it has high sensitivity and high-precision advantage.
For achieving the above object, Z shaft transmission of the present utility model comprises track base, Z axle longitudinally, it is characterized in that being provided with line slideway auxiliary and ball guide screw nat on track base and Z axle, being installed on the track base of the line slideway of line slideway auxiliary wherein, slide block is installed on the Z axle; The ball-screw of ball guide screw nat is installed on the track base, and nut is installed on the Z axle;
Because between the line slideway and slide block of line slideway auxiliary, be rolling friction between the ball-screw of ball guide screw nat and the nut, no creeping phenomenon has improved the sensitivity and the precision of transmission mechanism.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
By illustrated in figures 1 and 2, this Z shaft transmission, comprise the track base longitudinally 1, the Z axle 2 that are installed on the crossbeam 7, be arranged on line slideway auxiliary and ball guide screw nat on track base 1 and the Z axle 2, being installed on the track base 1 of the line slideway 3 of line slideway auxiliary wherein, slide block 4 is installed on the Z axle 2; The ball-screw 5 of ball guide screw nat is installed on the track base 1, and nut 6 is installed on the Z axle 2;
Because between the line slideway 3 and slide block 4 of line slideway auxiliary, be rolling friction between the ball-screw 5 of ball guide screw nat and the nut 6, no creeping phenomenon has improved the sensitivity and the precision of transmission mechanism.
