Abstract
The utility model relates to a straight stroke air cylinder, in particular to a double-layered air cylinder for a straight stroke air cylinder. The utility model designs a double-layered air cylinder 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 double-layered air cylinder comprises a cylinder body and a piston, wherein the cylinder body consists of an inner wall and an outer wall; and the inner wall is fixedly connected with the outer wall by a bolt.
Description
Technical field
The utility model relates to a kind of straight journey cylinder, relates in particular to a kind of double layer construction cylinder of straight journey cylinder.
Background technique
At present, cylinder is used in field of machining on a large scale as control piece, and the influence that its whole service life is subjected to cylinder wall working life is bigger.Increasing cylinder wall working life is the difficult problem of related domain.Though the improvement on cylinder wall is a lot of at present, great majority are the improvement to the cylinder material.Structural improvement is less, and framework improves when increasing cylinder wall working life, can reduce production costs.For example, a kind of domestic applications number are 02266204.9 air compressor Composite cylinder, comprise radiating fin and cylinder wall, cylinder wall is by inside and outside two-layer being composited, internal layer is the cylinder wall internal layer of the cylinder type that forms of cast iron casting, skin is aluminium matter cylinder wall skin and the radiating fin of integral die-cast in cylinder wall internal layer periphery, the outer surface concave-convex surface of cylinder wall internal layer.Though it has solved heat dissipation problem, for wear-resisting, improve casing wall and there is no improvement working life.
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 double layer construction cylinder 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 double layer construction cylinder of straight journey cylinder comprises cylinder body and piston, and described cylinder body is made up of inner and outer wall, adopts bolt to be connected between inwall and the outer wall.
As preferably, inwall is a working of plastics, and outer wall is a metalwork.Inwall is the working of plastics power of can reducing friction, and outer wall is that metalwork can increase bulk strength.Inner wall thickness is greater than outer wall thickness.The inner casing that inwall is formed is dismantled and assembled.By the dismounting joint outer part, open outer wall, replaceable frayed inwall.
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, has increased cylinder strength simultaneously.Be easy to dismounting, be convenient for changing impaired inwall.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, inwall, 2, outer wall.
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, described cylinder body is made up of inwall 1 and outer wall 2, adopts bolt to be connected between inwall and the outer wall.Inwall is engineering plastics, and outer wall is an aluminum.
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.
Claims (3)
