Background technique
In engineering machinery, can Arbitrary Rotation conveying water or other fluid medium rotary joint, generally use rotatory sealing
Or mechanical seal, but cannot all make straight reciprocating motion.And only make the oil cylinder of straight reciprocating motion, piston type, it is using special
The piston or piston rod seal component of door, but cannot all make circumnutation.This is the different sealing system of two classes, and same sealing
Part can not have both both functions substantially.But the hydraulic system components of some engineering machinery, it both requires to make circumnutation, again
It does reciprocating linear motion.These hydraulic system components put forward new requirements Seal Design and structure design.
Summary of the invention
The problem of for background above technology, the purpose of the utility model is to provide one kind can make convolution back and forth
Movement, and the water pipe rotary joint of linear reciprocation ballistic motion can be made, to adapt to the use demand of above-mentioned correlation engineering machinery.
The technical solution adopted in the utility model is: one kind can impact type water pipe rotary joint, including rotary shaft, rotation
Set, preceding gland, rear pressing cover, bearing, rotating seal and oil sealing, it is characterised in that: rotary sleeve and rotary shaft form rotary joint
Main body is used rotating seal and oil sealing sealing, is connected between rotary sleeve and rotary shaft with bearing support between rotary sleeve and rotary shaft
It connects；Rotary sleeve outer surface is machined with the threaded mouth of a river for being used to install transit joint, and inner surface is machined with peace in mouth of a river two sides
The groove of rotating seal is filled, both ends of the surface are machined with oil sealing installation position；Rotary shaft outer surface is machined with and rotary sleeve mouth of a river position
The annular groove of alignment is provided with water hole on annular groove；Gland and rear pressing cover before the both ends of rotary sleeve are respectively fitted with；In
The lower part of rotary sleeve is equipped with rolling guide, and rolling guide main body includes sliding block and guide rail, and sliding block is fixed on sliding block mounting plate, sliding
Block mounting plate is connect by bolt with rotary sleeve, and guide rail is fixed on mounting base.
Shield is installed outside the rolling guide.
Correlation engineering is fixed on mechanically by mounting base after the entire rotary joint combination of the utility model.
The technical solution of the utility model has the characteristics that following:
1, rotary joint can meet the function of correlation engineering machinery Arbitrary Rotation conveying water or other fluid medium；
2, the lower part of the rotary sleeve of rotary joint is equipped with rolling guide, can guarantee that entire rotary joint is light by rolling guide
It changes places and smoothly does reciprocating linear motion with high precision.
