Abstract

The utility model relates to a straight stroke air cylinder, in particular to a piston wear-resistant device for a straight stroke air cylinder. The utility model designs a piston wear-resistant device for a straight stroke air cylinder with the advantages of simple structure, long service life and easy part replacement aiming at the defects of short service life and complicated part replacement in the prior art. The main scheme is that the piston wear-resistant device comprises a cylinder body and a piston; a groove is formed on the edge of the piston; and a friction ring is embedded in the groove, protrudes out of the edge of the piston and is in contact with the cylinder body. The piston, which is not in direct contact with the cylinder body, is in contact with the cylinder through the friction ring; and the friction ring has small friction coefficient and is easy to replace.

Description

The piston abrasion-proof device of straight journey cylinder
Technical field
The utility model relates to a kind of straight journey cylinder, relates in particular to a kind of piston abrasion-proof device of straight journey cylinder.
Background technique
At present, the piston in the straight journey cylinder is an easily worn part because when work piston acutely rub with casing wall, meeting of long duration causes wearing and tearing.Need after the wearing and tearing the whole replacing of piston, even need to change this cylinder body.Some improvement are the improvement of integral material substantially at present, thereby have improved user cost.The improved procedure that also has is for improving cylinder body or structure of piston, and making it wear resistance increases.
For example, a kind of domestic applications number are 8720119 Double decker piston, the Double decker piston of quartastroke engine. this piston is made up of the piston of inside and outside two different structures. the other riveting of the inner top surface of outer piston has four equidistant guide pillars. inner carrier along have on the inwall length direction four corresponding with guide pillar to wearing guide pin bushing, the other end that four guide pillar rivetings are pushed up in outer piston stretches into the guide pin bushing cavity, connects with spring in the steel bushing respectively.Though such structure has been improved wear resistance, to replace also more conveniently, complex structure, material increase many, make the weight of piston increase, and use inconveniently, and energy consumption also increases.
Summary of the invention
The utility model mainly be in the prior art working life shortcoming such as weak point, part replacement complexity, designed the piston abrasion-proof device of the straight journey cylinder that a kind of simple in structure, long service life, parts be easy to change.
Above-mentioned technical problem of the present utility model is implemented by the following technical programs:
A kind of piston abrasion-proof device of straight journey cylinder comprises cylinder body and piston, and described piston edge is provided with groove, and groove is embedded with friction ring, and friction ring protrudes the piston edge and contacts with cylinder body.Piston does not directly contact with cylinder body, contacts with cylinder body by friction ring, and the friction ring friction factor is little, is easy to just change.
Described friction ring is a working of plastics.The working of plastics friction factor is little.
Described recess width is less than the friction ring width, and friction ring and groove are interference fit.The obturation effect of friction ring is more effective than original structure.
In sum, the utility model is compared with prior art and is had following advantage:
The utility model is simple in structure, is easy to realize, has reduced the cylinder internal friction, and the weight of piston does not significantly increase simultaneously, has reduced energy consumption.Be easy to dismounting, during replacing, the friction ring that only needs to change piston gets final product.Overall structure is simple, makes manufacture cost greatly reduce.
Description of drawings
Fig. 1 is a whole sectional drawing of the present utility model;
Fig. 2 is a sectional drawing enlarged view of the present utility model;
Number in the figure is: 1, piston, 2, groove, 3, friction ring.
Embodiment
Below by embodiment, in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail:
Embodiment 1:
As Fig. 1, Fig. 2, shown in, the utility model comprises cylinder body and piston 1, described piston edge is provided with groove 2, groove is embedded with friction ring 3, friction ring protrudes the piston edge and contacts with cylinder body.Friction ring is a working of plastics.Recess width is less than the friction ring width, and friction ring and groove are interference fit.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
