Abstract
The utility model discloses a multistage hydraulic cylinder position limiting support ring, which comprises two copper alloy rings. The copper alloy rings are welded with the outer wall of an inner cylinder tube for fixation and then are machined for shaping. Both of the two copper alloy rings play the roles of guiding, supporting and position limiting. The hardness of copper is between the hardness of poly-fluorinated plastic and the hardness of cast iron. The position limiting support ring can well ensure the coaxiality, has small friction with the cylinder tube, and has small wear to the inner wall of the cylinder tube.
Description
Technical field
The utility model belongs to spacing support device, is specifically related to the spacing support ring of a kind of multistage hydraulic cylinder.
Background technique
Be provided with limited ring, support ring between two cylinder barrels of multistage hydraulic cylinder, two kinds of forms of the many employings of the limited ring of known multistage hydraulic cylinder and support ring, a kind of is the whole processing of limited ring and cylinder barrel, makes the guiding support ring with poly-fluoroplastic again; Another kind is to adopt embedded snap ring structure, and limited ring and support ring embed respectively in the cylinder barrel outer wall trench, and bipassage ring plays a part spacing respectively and guiding supports, and support ring adopts cast iron more.These two kinds of forms all exist certain shortcoming, the former, technology capability is relatively poor, the cost height; And the latter's support ring is because adopt cast iron materials, the big easy scratch casing wall during with the casing wall relative movement of hardness, influence use; And embedded limited ring spacing unreliable, come off easily.
The model utility content
In order to overcome the above-mentioned defective that the known technology field exists, the purpose of this utility model is, provides a kind of multistage hydraulic cylinder spacing support ring, and it is low to be connected firmly, to be convenient to processing, good manufacturability, cost.
The spacing support ring of the multistage hydraulic cylinder that the utility model provides, comprise twice Cuprum alloy ring, described Cuprum alloy ring and the welding of inner cylinder tube outer wall are fixing, carry out machine shaping again after the spacing support ring welding of Cuprum alloy is fixing, and the Cuprum alloy ring plays guiding and supports and position-limiting action.
The spacing support ring of the multistage hydraulic cylinder that the utility model provides, limited ring adopt Cuprum alloy and cylinder barrel outer wall welding back machine shaping, can be good at guaranteeing coaxality; The hardness of copper is between poly-fluoroplastic and cast iron, and the friction between the cylinder barrel is little, and is little to the inner wall of cylinder wearing and tearing; Because the Cuprum alloy limited ring can play the effect of guiding, it and casing wall friction during the cylinder barrel operation, relative inner wall of cylinder, the Cuprum alloy limited ring is more easy to wear, can shield to inner wall of cylinder like this; Select Cuprum alloy for use, recoverability is good, and repair welding processing again can guarantee preferably with cooperating also of former cylinder barrel after the wearing and tearing.
Description of drawings
Fig. 1 is an embodiment's of the utility model a structural representation.
Mark among the figure:
1. inner cylinder tube; 2. Cuprum alloy ring I; 3. Cuprum alloy ring II.
Embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the spacing support ring of multistage hydraulic cylinder that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1, the spacing support ring of the multistage hydraulic cylinder of present embodiment, comprise twice Cuprum alloy ring I2, Cuprum alloy ring II3, described Cuprum alloy ring I2, Cuprum alloy ring II3 and the welding of inner cylinder tube 1 outer wall are fixing, the Cuprum alloy boxing is carried out machine shaping after connecing and fixing again, and the Cuprum alloy ring plays guiding and supports and position-limiting action.
Claims (1)
1. spacing support ring of multistage hydraulic cylinder is characterized in that: comprise twice Cuprum alloy ring, described Cuprum alloy ring and the welding of inner cylinder tube outer wall are fixing, and the Cuprum alloy ring plays guiding and supports and position-limiting action.
