Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings (left and right directions and above-below direction in following description with
Left and right directions in Fig. 1 is identical with above-below direction).
As shown in Figure 1 to Figure 3, a kind of hydraulic press buffer gear, including left cushion cylinder 2, right cushion cylinder 6 and adjustable
Mechanism, described left cushion cylinder 2 and right cushion cylinder 6 respectively by several screws 1 be arranged on sliding block 1 lower left and
Lower right；Adjustable mechanism described in two is respectively provided at the left and right of mobile work platform 5, in the vertical direction respectively with
Left cushion cylinder 2 and right cushion cylinder 6 are corresponding；Described adjustable structure includes support 9, adjusting screw rod 10, locking nut
11 and fixing nut 12, described fixing nut 12 is arranged on the upper surface of mobile work platform 5 by some screws 2 13, described
Adjusting screw rod 10 epimere and the screw thread of fixing nut 12 coordinate, lower end be combined with through the rear thread of mobile work platform 5 it is described
