Abstract
The utility model discloses a kind of relay guide ring, comprise ring body, it is characterized in that: described ring body is cylindrical body, described ring body is provided with ring body concentric and the cylindrical cavity run through up and down, described ring body upper surface is provided with the first ladder surface and second-order tread, described first ladder surface is U-shaped face, and described second-order tread is two bow shaped surface, and described ring body is symmetrical.Relay guide ring of the present utility model prevents piston or piston rod that piston or piston rod occur with cylinder body directly to contact and avoid in movement process and produces with cylinder body in movement process and rub, and improves serviceability and the control accuracy of sudden-pressure relay.
Description
Technical field
The utility model relates to sudden-pressure relay field, especially relates to a kind of guide ring of sudden-pressure relay.
Background technique
Guide ring is the part of on a kind of piston for oil hydraulic cylinder or cylinder or piston rod, support piston or piston rod movement, sudden-pressure relay is hydraulic component pressure being converted to electrical signal, be widely used in hydraulic system, the friction between piston and cylinder body produces significantly impact to the control accuracy of sudden-pressure relay.Current sudden-pressure relay is owing to having friction between piston and cylinder body, and sudden-pressure relay control accuracy is not high, is not durable.
Model utility content
The purpose of this utility model is to design a kind of relay guide ring, can effectively prevent piston or piston rod from occurring directly to contact and rub with cylinder body in movement process, improves serviceability and the control accuracy of sudden-pressure relay.Unresolved above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of relay guide ring, comprise ring body, it is characterized in that: described ring body is cylindrical body, described ring body is provided with ring body concentric and the cylindrical cavity run through up and down, described ring body upper surface is provided with the first ladder surface and second-order tread, described first ladder surface is U-shaped face, and described second-order tread is two bow shaped surface, and described ring body is symmetrical.
Further, described ring body is provided with symmetrical a pair screw on second-order tread, and screw axis and ring body shaft axis are at grade.
Further, described ring body upper surface is provided with two screws.
Further, on described ring body upper surface two screw axis and second-order tread, two screw axis are positioned on same anchor ring.
Further, described ring body exterior surface is provided with the through hole of several annular arrays.
Further, described through hole number is 6, and described through hole is tapped hole.
Further, described ring body exterior surface and lower surface junction are provided with chamfering.
Further, described ring body internal surface and lower surface junction are provided with chamfering.
By arranging U-shaped ladder surface and arcuate ladder surface to ring body and arranging screw and through hole, the beneficial effects of the utility model are: prevent piston or piston rod that piston or piston rod occur with cylinder body directly to contact and avoid in movement process and produce with cylinder body in movement process and rub, improve serviceability and the control accuracy of sudden-pressure relay.

Embodiment
Below in conjunction with drawings and Examples, the utility model is illustrated further:
As Fig. 1, Fig. 2, shown in Fig. 4, a kind of relay guide ring, comprises ring body, described ring body is cylindrical body, described ring body is provided with ring body concentric and the cylindrical cavity 1 run through up and down, and described ring body upper surface is provided with the first ladder surface 2 and second-order tread 3, and described first ladder surface 2 is U-shaped face, described second-order tread 3 is two bow shaped surface, and described ring body is symmetrical.
Described ring body is provided with symmetrical a pair screw on second-order tread 3, and screw axis and ring body shaft axis are at grade.Described ring body upper surface is provided with two screws.
On described ring body upper surface two screw axis and second-order tread 3, two screw axis are positioned on same anchor ring.
As shown in figs. 2 to 4, described ring body exterior surface is provided with the through hole of several annular arrays.Described through hole number is 6, and described through hole is tapped hole.Described ring body exterior surface and lower surface junction are provided with chamfering.Described ring body internal surface and lower surface junction are provided with chamfering.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, all drop within protection domain of the present utility model.
