Abstract

The utility model relates to an air compressor piston installer. A conical hole is arranged on the inner wall of the installer. An annular clamp slot which is used for being clamped on a piston cylinder is arranged on a small caliber end of the conical hole. The diameter of the small caliber end of the conical hole is equal to the inner diameter of the piston cylinder. The inner diameter of the annular clamp slot is matched with the outer diameter of the piston cylinder. An opening through which a piston rod passes is arranged on the side wall of the installer. The width of the opening is greater than the outer diameter of the piston rod. The outer wall of the installer is cylindrical. The installer mainly solves the problem that a piston is difficultly placed into the piston cylinder body under the condition that a piston ring exists.

Description

Air-compressor piston erector

Technical field

The utility model relates to a kind of air-compressor piston erector, belongs to rail vehicle service technique field.

Background technology

Piston type air compressor is a kind of of reciprocating compressor, its operation principle is: during work, motor is by the direct driving crank of shaft joint, drivening rod, crosshead and piston rod, make piston reciprocating in the cylinder of compressor, completes the processes such as suction, compression, discharge.In air compressor work, in order to prevent that the fluid in air compressor cavity from entering into valve block position, valve block is polluted or corroded, therefore ring installation on piston, in case the generation of class item here.But because piston ring is a kind of elastic opening ring, diameter under its nature is greater than the internal diameter of piston/cylinder, to such an extent as to piston is difficult to be loaded into cylinder, so just to production efficiency, caused very large harmful effect, increase very large difficulty also to workman's work simultaneously, so need to design a kind of simple and practical frock, solve this problem.

Utility model content

The purpose of this utility model is: the defect that overcomes above-mentioned prior art, a kind of air-compressor piston erector is proposed, it is rational in infrastructure, it is a kind of technological equipment that can effectively reduce piston installation difficulty, thereby reduced workman's work difficulty, improve work comfort level and operating efficiency, also adapted to the demand of producing in enormous quantities, improved product quality.

In order to achieve the above object, a kind of air-compressor piston erector the utility model proposes, it is characterized in that, described erector inwall is shaped with bellmouth, small-bore one end of described bellmouth is shaped with for being stuck in the annular slot on piston cylinder, the diameter of small-bore one end of described bellmouth equates with piston cylinder internal diameter, and the internal diameter of annular slot and piston cylinder external diameter match.

The sidewall of the utility model erector offers and holds the opening that piston rod passes through, and A/F is greater than piston rod external diameter.

The utility model erector outer wall is cylindric.

The utility model adopts technique scheme tool to have the following advantages:

1, effectively reduce the work difficulty that piston is installed, and then improved greatly operating efficiency;

2, the major advantage of this erector be simple in structure, be convenient to processing, select popular material to carry out processing and manufacturing, cost is lower.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is the utility model air-compressor piston erector structural representation.

Fig. 2 is the cutaway view of the utility model air-compressor piston erector.

Fig. 3, Fig. 4 are the schematic diagram of the utility model air-compressor piston erector when piston is installed.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

As depicted in figs. 1 and 2, the utility model embodiment air-compressor piston erector, inwall is shaped with bellmouth 1, small-bore one end of bellmouth 1 is shaped with for being stuck in the annular slot 2 on piston cylinder, the diameter of small-bore one end of bellmouth 1 equates with piston cylinder internal diameter, and the internal diameter of annular slot 2 and piston cylinder external diameter match.

As shown in Figure 1, the sidewall of erector offers and holds the opening 3 that piston rod passes through, and opening 3 width are greater than piston rod external diameter.

As shown in Figure 1, erector outer wall is cylindric.

Use erector to install before piston 4, first piston 4 and piston rod combined, then start the installation of piston 4 and piston ring 5:

The first step, piston/cylinder is embedded in the annular slot 2 of erector, then in order guaranteeing, when piston 4 is installed, can easier piston 4 to be pressed in piston/cylinder, can not to damage again piston ring 5 and erector inwall, need smear lubricant at the inwall of erector simultaneously;

Second step, as shown in Figure 3, piston ring 5 is enclosed within on piston 4, then by the piston with piston ring 54, the axis direction from the maximum gauge of bellmouth 1 along bellmouth 1 packs into, because erector inwall maximum gauge is greater than piston ring 5 diameters, so piston ring 5 can be put in erector easily;

The 3rd step, when piston ring 5 moves to erector inner diameter and equates with piston ring 5 external diameters, along bellmouth 1 axial direction, exert oneself a little, now because piston ring 5 is elastic opening ring, so along with applying of external force, piston 4 moves along bellmouth 1 axial direction with piston ring 5 integral body, and piston ring 5 diameters reduce along with reducing of erector internal diameter simultaneously.

The 4th step, as shown in Figure 4, when piston 4 moves to the position of erector internal diameter minimum, piston ring 5 is also compressed to minimum state, now the diameter of piston ring 5 is minimum, and is less than the internal diameter of piston-cylinder, and piston 4 and piston ring 5 are just pressed in the middle of cylinder easily like this.

The 5th step, after piston 4 installs, final step work is that erector is taken off from piston-cylinder, due to before piston 4 is pressed into cylinder, piston rod and piston 4 are combined, and the size of piston rod is slightly larger than the minimum diameter of erector, so take off the opening 3 that erector need to leave from erector side, erector is taken off smoothly from piston rod one side, and whole installation process so far finishes.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
