AI Technical Summary
When the worktable of an existing horizontal boring and milling machine moves to both ends of the slide saddle, it sags due to poor support rigidity, resulting in reduced accuracy. In particular, the longer the overhang, the worse the rigidity and the greater the change in accuracy.
The cross slide structure is adopted. Through the sliding connection of the first and second adjusting bars and the combination of ball bearings, support blocks and casters, combined with the limiting fixation of the switch-type magnetic base, the stable adjustment and fixation of the carrier plate can be achieved.
It improves the stability of the carrier plate during adjustment and use, avoids carrier plate tilting, and ensures the stability and consistency of processing accuracy.

[0018] In this technical solution, the first adjusting strip 13 on the bottom side of the carrier plate 12 is slidably connected to the second adjusting strip 15 on the upper surface of the bed body 1 through the second adjusting groove 16, which allows the carrier plate 12 to be adjusted in the front and back position. The second adjusting strip 15 is slidably connected to the first adjusting groove 14 on the first adjusting strip 13, which allows the carrier plate 12 to be adjusted in the left and right position. The structure is simple and easy to operate.
[0019] In this embodiment, the bottom inner wall of the second adjustment groove 16 is uniformly provided with balls 17, which are rolledly connected to the bottom side of the first adjustment bar 13. Support blocks 2 are welded to the four corners of the bottom side of the carrier plate 12, and universal wheels 21 are fixedly connected to the bottom of the support blocks 2. Universal wheels 21 are rolledly connected to the upper surface of the bed body 1.
[0020] In this technical solution, the ball bearings 17 on the inner wall of the bottom of the second adjustment groove 16 save physical effort when pushing the carrier plate 12 to adjust its position. The stability of the carrier plate 12 during adjustment and use can be improved by the four sets of support blocks 2 and the universal wheels 21, and the carrier plate 12 can be prevented from tilting.
[0021] In this embodiment, the front and rear ends of the first adjusting bar 13 are fixedly connected to a switch-type magnetic base 18, and the bottom end of the magnetic base 18 is attached to the upper surface of the bed body 1.
