High-pressure supporting and smooth and steady lifting mechanism

Abstract

The invention provides a high-pressure supporting and smooth and steady lifting mechanism. The high-pressure supporting and smooth and steady lifting mechanism comprises a vertical column positioning bottom plate and a supporting plate, wherein the vertical column positioning bottom plate is provided with a lifting mechanism body, and the supporting plate is fixed to equipment; two adjusting rail bottom plates are arranged on the two ends of the supporting plate, and an adjusting rail base is arranged on the adjusting rail bottom plate; an adjusting rail shaft is arranged on the adjusting rail base, and an adjusting sliding block used for realizing left-right adjusting of a position are arranged on the adjusting rail shaft; the vertical column positioning bottom plate is arranged on the adjusting sliding block; an adjusting rod base is arranged on the side face of one end of the adjusting rail bottom plate, and an adjusting rod is arranged on the adjusting rod base; the adjusting rod is connected with one end of an adjusting lead screw through an adjusting bevel gear group, and the other end of the adjusting lead screw is fixed on the vertical column positioning bottom plate through a lead screw adjusting block. According to the high-pressure supporting and smooth and steady lifting mechanism, functions of supporting high pressure and more stable and high efficient of lifting action of a machine operating work station are achieved by utilizing an ordinary air cylinder, the bearing capacity of the mechanism is enhanced, the load of the air cylinder is reduced, the service life of the air cylinder is prolonged, adjusting is convenient, and meanwhile the adjusting precision is increased.

Description

technical field [0001] The invention relates to a mechanism which utilizes an ordinary cylinder to support high pressure and provide stable and high-efficiency effects for the lifting and lowering of machine operating stations. Background technique [0002] like figure 1 and figure 2 As shown, the existing lifting mechanism is mainly composed of a column positioning base plate 1, adjusting inner swing arm 2, base plate connecting plate 3, cylinder fixing plate 4, cylinder 5, adjusting guide plate 6, adjusting outer swing arm 7, adjusting swing arm positioning screw 8. The three-axis conjoined block 9, the adjustment fixed block 10, the adjustment short shaft 11, the cylinder connecting seat 12, the adjustment long shaft 13, the rolling bearing 14, etc. are composed of an axisymmetric structure. [0003] The cylinder fixing plate 4, the adjusting guide plate 6, and the adjusting and fixing block 10 are installed on the column positioning base plate 1 according to the corre...

Problems solved by technology

[0008] Use the cylinder alone to realize the up and down movement. Although the up and down movement of the mechanism can also be realized, the cylinder itself has certain instability. When the air pressure is unstable, insufficient, or the reaction force of the connecting parts on the cylinder is too large, it will cause The cylinder has a phenomenon of retreating downwards, which leads to the failure to ensure 100% closure between the workpieces, and the pressing is not tight enough to achieve the expected effect
