Embodiment 1
[0036] Basic as attached figure 1 , figure 2 Shown: flat guide rail platform machine tool, including bed, bed includes bed base 1, saddle guide rail and tailstock guide rail fixed longitudinally on bed base 1 by bolts, bed saddle guide rail includes first saddle guide rail arranged in parallel 2 and the second saddle rail 8, the height of the first saddle rail 2 and the second saddle rail 8 are the same; the tailstock rail includes the first tailstock rail 3 and the second tailstock rail 9 arranged in parallel, the first The seat guide rail 3 is lower than the second tailstock guide rail 9, the second tailstock guide rail 9 is lower than the saddle guide rail, and the first tailstock guide rail 3, the second tailstock guide rail 9 and the second saddle guide rail 8 are arranged in steps. The top surfaces of the saddle guide rail and the tailstock guide rail are all parallel to the positioning reference plane at the bottom of the bed base 1 .

Embodiment 2
[0043] Such as Figure 3 ~ Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that a slider 12 is slidably connected to the tailstock guide rail, and the structure of the slider 12 will be described by taking the slider 12 on the first tailstock guide rail 3 as an example, as Figure 4 , Figure 5 As shown, the slider 12 is provided with a through hole 13, and the through hole 13 is along the length direction of the negative pressure chamber 14 ( Figure 5 ) has one, along the cross-sectional direction of the negative pressure chamber 14 ( Figure 4 ) has multiple, three are shown in the figure; oil-absorbing block is fixedly bonded in the through hole 13, and the oil-absorbing block is a sponge block, and the shape and size of the sponge block are the same as the through hole 13; the through hole 13 is equipped with The first one-way valve, the first one-way valve is located on the upper side of the oil suction block; the lower end of the through ...
Embodiment 3
[0048] Such as Figure 7 , Figure 8 As shown, the difference between the present embodiment and the second embodiment is that the driving mechanism includes a transmission gear 21 and a first rack, the first rack is integrally formed on the lower side of the piston rod 17, and the left and right ends of the piston rod 17 are left There is a section of smooth section, and the length of the first rack is equal to the stroke length of the piston 16 in the negative pressure chamber 14, and the two ends of the first rack are respectively hinged with hinged teeth through pivot pins. For the convenience of description, the first rack The articulated teeth at the left end of a rack are named as the first articulated teeth 22, and the articulated teeth at the right end of the first rack are named as the second articulated teeth. Vertical symmetry. Take the first hinged tooth 22 as an example below to illustrate its structure: the first rack right above the first hinged tooth 22 has ...
