Description
Technical field
The present invention relates to cylinder technical field, particularly, relate to a kind of cylinder piston being convenient to install.
Background technique
Air motor is the power equipment of automobile, for the automobile in travelling provides continuous driving force.Air motor generally produces power by gas, is driven by cylinder, and the piston of cylinder is used for bearing gas pressure, and is rotated by piston rod and rack drives gear.
Therefore, the requirement of piston is very high:
(1) because piston is ceaselessly subject to cyclic stress effect at work, need there is enough strength and stiffness;
(2) because piston moves back and forth, so piston needs quality little, lightweight, thus the inertial force of piston in movement process is reduced;
(3) good thermal conductivity, absorbs heat from the external world as much as possible after doing work, improve the capacity usage ratio of gas to make high pressure gas expansion.
And a lot of piston does not often reach above-mentioned requirements at present, in addition, piston is arranged in the cylinder barrel of cylinder, should ensure easy for installation, also will ensure the tightness of piston.
Summary of the invention
Object of the present invention is just the shortcoming and defect overcoming above-mentioned prior art, is provided in the cylinder piston being convenient under ensureing the bubble-tight prerequisite of piston install.
The present invention's adopted technological scheme that solves the problem is:
Be convenient to the cylinder piston installed, comprise piston only, the boss be arranged on two end faces of piston only of annular; Described piston only center offers pin-and-hole, one of them boss center offers piston rod mounting hole, another boss center offers positioning hole, and pin-and-hole two ends are all communicated with piston rod mounting hole, positioning hole and pin-and-hole, positioning hole, the central axis of piston rod mounting hole and the central axes of piston only.
As a further improvement on the present invention, the outer peripheral surface of described piston only is arranged with positioning ring, seal ring, magnet ring, positioning ring, seal ring, magnet ring are arranged side by side along the axial direction of piston only, and positioning ring (3) and magnet ring lay respectively at seal ring both sides.
Further, an end face of described piston only offers the first annular groove, another end face offers the second annular groove.
Further, described first annular groove is a step trough, and be made up of the outer groove away from piston only center and the inner groove near piston only center, outer groove is connected with inner groove, and outer groove diameter is greater than inner groove.
Further, described boss ringwise, the outer peripheral surface of one of them boss is provided with screw thread.
Preferably, described piston only and boss adopt aluminum alloy to make, and described seal ring adopts rubber to make.。
To sum up, the invention has the beneficial effects as follows:
1, the structure of piston of the present invention is ensureing the installation being convenient to piston rod under the bubble-tight prerequisite of piston;
2, piston only of the present invention and boss adopt aluminum alloy to make, and have good rigidity, intensity, and lightweight, good conductivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Mark and corresponding component title in accompanying drawing: 1-piston only; 2-pin-and-hole; 3-positioning ring; 4-seal ring; 5-magnet ring; 6-boss; 71-piston rod mounting hole; 72-positioning hole; 8-first annular groove; 81-outer groove; 82-inner groove; 9-second annular groove.
Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the present invention's do, but embodiments of the present invention are not limited thereto.
As shown in Figure 1, be convenient to the cylinder piston installed, comprise piston only 1 and two annular boss 6 of annular.Two boss 6 are separately positioned on two end faces of piston only 1, the central axis of two annular boss 6 all with the central axes of piston only 1.
Piston only 1 center offers pin-and-hole 2, in two annular boss 6, one of them boss 6 center is provided with piston rod mounting hole 71, another boss 6 center offers positioning hole 72, pin-and-hole 2 two ends be communicated with piston rod mounting hole 71, positioning hole 72 and the central axis in three holes all with the central axes of piston only 1.The outer peripheral surface of one of them boss 6 is provided with screw thread.
An end face of described piston only 1 offers the first annular groove 8, another end face offers the second annular groove 9; Described first annular groove 8 is a step trough, and be made up of the outer groove 81 away from piston only 1 center and the inner groove 82 near piston only 1 center, outer groove 81 is connected with inner groove 82, and outer groove 81 diameter is greater than inner groove 82.The internal diameter of the first annular groove 8, second annular groove 9 is all less than the external diameter of boss 6, and boss 6 is positioned at the first annular groove 8 or the second annular groove 9 center.
Aforementioned pin-and-hole 2, boss 6, first annular groove 8, second annular groove 9, piston rod mounting hole 71, positioning hole 72 are for installing piston rod, and said structure makes the easy for installation, stable of piston rod.
The outer peripheral surface of piston only 1 is arranged with positioning ring 3, seal ring 4, magnet ring 5, positioning ring 3, seal ring 4, magnet ring 5 are arranged side by side along the axial direction of piston only 1, and positioning ring 3 and magnet ring 5 lay respectively at seal ring 4 both sides.Positioning ring 3, for the location between piston and the cylinder barrel of cylinder, is avoided piston to form torsional moment in the course of the work and is produced pull-cylinder phenomena; Seal ring 4, for the sealing of piston and inner wall of cylinder, prevents Leakage Gas.
Described piston only 1 and boss 6 adopt aluminum alloy to make.Intensity of aluminum alloy is high, density is little, and the thermal conductivity of aluminium is only second to copper, therefore select aluminum alloy for piston in the present embodiment, experiment proves that the stress suffered by piston in the present embodiment is all less than its yield strength, piston has good rigidity, intensity, and lightweight, good conductivity.Described seal ring 4 adopts rubber to make.
Piston of the present invention adopts said structure, is ensureing the installation being convenient to piston rod under the bubble-tight prerequisite of piston.
Below be only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, all technological schemes belonged under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, should be considered as protection scope of the present invention.
