Abstract
The utility model relates to an air floatation cylinder device. The air floatation cylinder device comprises a cylinder, a piston is arranged in the cylinder, the front part of the piston is contained in an air floatation shaft sleeve, the tail of the piston is connected to the inner wall of the cylinder through a reset spring, a gap is formed between the piston and the air floatation shaft sleeve, a pressure applying air inlet is formed in the tail end of the cylinder, and an air floatation air inlet is formed in the position, corresponding to the middle of the cylinder shaft sleeve, of the top end of the cylinder. The air floatation cylinder device has the advantages that the piston rotates in the air floatation shaft sleeve according to the air floatation principle, so that the air floatation cylinder device is high in operation speed and accuracy, and the gap is formed between the piston and the shaft sleeve due to air floatation, so that friction or abrasion does not exist, and the service life of the air floatation cylinder device is long; oiling is not needed, so that operation cost of the air floatation cylinder device is saved.
Description
Technical field
The utility model relates to a kind of floating cylinder device.
Background technique
cylinder is a kind of device conventional on power equipment, and power resources, mainly by the promotion of piston, are arranged in axle sleeve on piston is general, and piston moves reciprocatingly in cylinder.Existing piston is generally to reduce the friction between axle sleeve by bath lubrication.Wearing and tearing between method piston and the axle sleeve of this employing bath lubrication are large, and equipment motion speed is limited, and affect the working life of equipment; To often refuel simultaneously, increase the operating cost of equipment.
Model utility content
The purpose of this utility model is to provide a kind of floating cylinder device, to overcome prior art above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
A kind of floating cylinder device, comprise cylinder, in described cylinder, be provided with piston, the front portion of described piston is placed in air suspension shaft sleeve and afterbody is connected on cylinder inner wall by Returnning spring, between described piston and air suspension shaft sleeve, form gap, the tail end of described cylinder is provided with the suction port of exerting pressure, and the top of described cylinder is provided with air supporting suction port in the position at corresponding cylinder axle sleeve middle part.
Further, the tail end of described piston is provided with end cap, and described Returnning spring is connected with end cap.
Further, described air suspension shaft sleeve outer is arranged with some seal rings.
The beneficial effects of the utility model are: floating cylinder device of the present utility model adopts air supporting principle that piston is turned round in air suspension shaft sleeve, and motion speed is high, and validity is high; Air supporting makes to form gap between piston and axle sleeve, and without friction, without wearing and tearing, service life of equipment is long; And without oiling, save equipment operating cost.
Brief description of the drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the floating cylinder device schematic diagram described in the utility model embodiment.
In figure:
1, cylinder; 2, piston; 3, air suspension shaft sleeve; 4, end cap; 5, Returnning spring; 6, the suction port of exerting pressure; 7, air supporting suction port; 8, cylinder inner wall; 9, seal ring.
Embodiment
As shown in Figure 1, floating cylinder device described in the utility model embodiment, comprise cylinder 1, in described cylinder 1, piston 2 is installed, the front portion of described piston 2 is placed in air suspension shaft sleeve 3, the tail end of piston 2 is provided with end cap 4, on the end cap 4 of piston 2, be connected with Returnning spring 5, piston 2 is connected on cylinder inner wall 8 by Returnning spring 5, between described piston 2 and air suspension shaft sleeve 3, form gap by air supporting, air supporting suction port 7 air inlets that cylinder 1 arranges in the position at corresponding cylinder axle sleeve 3 middle parts by its top; The tail end of described cylinder 1 is provided with the suction port 6 of exerting pressure, and promotes piston 2 move by suction port 6 air inlets of exerting pressure.Described air suspension shaft sleeve 3 outer is arranged with some seal rings 9, and the quantity of seal ring 9 is preferably three.
The working principle of the floating cylinder device described in the utility model embodiment is: cylinder 1, by suction port 6 air inlets of exerting pressure, promotes piston 2 and advances, and piston 2 resets by the pulling force of Returnning spring 5, and piston 2 moves reciprocatingly.Cylinder 1, by 7 air inlets of air supporting suction port, makes to form gap between piston 2 and air suspension shaft sleeve 3, and piston 2, moves thereby make to form nothing friction between piston 2 and air suspension shaft sleeve 3 in the interior rotation of air suspension shaft sleeve 3 by air supporting.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technological scheme, within all dropping on protection domain of the present utility model.
