Embodiment Construction
[0028] Further illustrate the present invention below in conjunction with accompanying drawing.
[0029] Such as Figure 1 to Figure 4 As shown, the stepper motor 1 is installed on the support base 2, and drives the screw 4 through the coupling 3; the nut 5 is fixedly connected with the slider 6, and the light hole on the slider 6 is slidably matched with the stop guide rod 7 , the limit nut can only move in a straight line; V-shaped ball guide rails 9 and 10 are installed between the two sides of the slider 6 and the inner sides of the left and right columns of the sensor mounting frame 8, so that the mounting frame 8 can move up and down; the left and right columns of the mounting frame 8 Bearings 11 and 12 are respectively housed on the outer surfaces; the two bearings roll along profiling guide rails 13 and 14 respectively. When the slider 6 (connected with the nut 5) moves linearly, the force is transmitted to the sensor mounting frame 8 through the V-shaped ball guide r...
