Abstract
The invention discloses a sand grinding rotary connector. A deep-groove ball bearing is mounted between a water outlet pipe and a bearing pedestal in a sleeving way; one end of the water outlet pipe is connected with the main shaft of used equipment and rotates along with the main shaft; the bearing pedestal is located at the top end of a casing; a water inlet pipe is mounted in the casing, and one end of the water inlet pipe is in spherical sealing and contact with one end of the water outlet pipe; an O-shaped gasket ring is mounted between the water inlet pipe and the water outlet pipe for playing a role of auxiliary sealing; a cylindrical compression spring is mounted between the water inlet pipe and an adjustable threaded sleeve in a propping way and is used for automatically compensating contact surface pressure of an arc outer sphere and an arc inner sphere, and fixes and adjusts the position of the threaded sleeve via a round nut; a pin is arranged at the lower part of the water inlet pipe and enables the water inlet pipe to vertically move but not rotate in a straight groove for adjusting the threaded sleeve; an anti-rotation bolt is arranged on the casing and connected with the used equipment for preventing the casing from rotating during mounting. The sand grinding rotary connector has the advantages of compact structure, good sealing performance, long service life and the like, and has high popularization value.
Description
Technical field:
The present invention relates to a kind of swivel joint, relate in particular to a kind of seal connection for grinding mortar and be input to from static pipeline rotating equipment.
Background technique:
Swivel joint is for having single pass through-type seal connection; flowing medium (air, cooling liquid, hydraulic oil) is input to the rotating equipment from static pipeline; to solve run, drip, leak; energy saving; protection of the environment, requisite mechanical connection basis critical component improves working conditions.
In the superfinish technique of contemporary optics and high-precision metal spare, frosted processing is necessary technique, namely when the work of grinding, adds emery and form the grinding mortar in lapping liquid, grinds mortar and is transported in the rotating equipment by swivel joint; At present, swivel joint is of a great variety on the market, price comparison is expensive, and be only suitable for air, cooling liquid, hydraulic pressure wet goods flowing medium, when carrying the grinding mortar, its seal arrangement only will be damaged in several hours, and then restricted greatly the working life of swivel joint, can't use in frosting technology; What adopt now is artificial filling, has the shortcomings such as labor intensity is large, manufacturing efficiency is low.
Summary of the invention:
Patent of the present invention is for the deficiencies in the prior art, provide a kind of rational in infrastructure, price is low, without leak, manufacturing efficiency is high, the frosted swivel joint of long service life.
For realizing above purpose, the technological scheme that patent of the present invention adopts is:
The frosted swivel joint is comprised of outlet pipe, bearing support, deep groove ball bearing, housing, socket head screw, intake pipe, O RunddichtringO, cylindrical compression spring, adjustment swivel nut, round nut, pin, anti-turn bolt; Deep groove ball bearing is sleeved between outlet pipe and the bearing support, and outlet pipe one end is connected with the use machine spindle, rotates with main shaft; Bearing seat is in the housing top; Intake pipe is installed in the housing, and intake pipe one end and outlet pipe one end adopt the sphere sealing that contacts; The O RunddichtringO is installed between intake pipe and the outlet pipe, plays the auxiliary seal effect; The cylindrical compression spring top is contained in intake pipe and adjusts between the swivel nut, and the interface pressure between auto-compensation arc outer spherical surface and the arc inner ball surface is by the position of round nut locking adjustment swivel nut; Described intake pipe below is provided with pin, makes intake pipe vertical motion and can not rotating in the straight trough of adjusting swivel nut; Described housing is provided with anti-turn bolt, prevents that with the equipment connection that uses housing from rotating during installation.
Be connected with socket head screw between described bearing support and the housing.
Described intake pipe one end is the arc outer spherical surface, and described outlet pipe one end is the arc inner ball surface, the sealing that contacts with the arc inner ball surface of arc outer spherical surface, and arc outer spherical surface and arc inner ball surface be tangent to have the self-aligning seal action.
Patent of the present invention advantage compared with prior art is: intake pipe one end is the arc outer spherical surface, outlet pipe one end is the arc inner ball surface, the sealing that contacts with the arc inner ball surface of arc outer spherical surface, arc outer spherical surface and arc inner ball surface be tangent to have the self-aligning seal action; The cylindrical compression spring top is contained in intake pipe and adjusts between the swivel nut, interface pressure between auto-compensation arc outer spherical surface and the arc inner ball surface, swivel joint inner cylinder Compress Spring relatively static, add that cylindrical compression spring is not subjected to the impact of warping stress, so cylindrical compression spring is more stable to the compensation of sealing surface; Grinding mortar enters in the intake pipe, the intake pipe below is provided with pin, intake pipe vertical motion and can not rotating in adjusting the straight trough of swivel nut, grinding mortar flows in the outlet pipe subsequently, outlet pipe is discharged finally by outlet pipe with the rotation of use machine spindle, realizes grinding mortar and enters machining area, need not to adopt artificial filling, and then prolong the working life of swivel joint; When phenomenons such as appearance leakages, only need to change the O RunddichtringO, maintenance cost is low, and is applied widely.
Description of drawings:
Fig. 1 is the sectional view of patent of the present invention.
Embodiment:
As shown in Figure 1, the frosted swivel joint is comprised of outlet pipe 1, bearing support 2, deep groove ball bearing 3, housing 4, socket head screw 5, intake pipe 6, O RunddichtringO 7, cylindrical compression spring 8, adjustment swivel nut 9, round nut 10, pin 11, anti-turn bolt 12; Deep groove ball bearing 3 is sleeved between outlet pipe 1 and the bearing support 2, and outlet pipe 1 one ends are connected with use machine spindle (not shown), rotate with the main shaft (not shown); Bearing support 2 is positioned at housing 4 tops; Intake pipe 6 is installed in the housing 4, and intake pipe 6 one ends and outlet pipe 1 one ends adopt the sphere sealing that contacts; O RunddichtringO 7 is installed between intake pipe 6 and the outlet pipe 1, plays the auxiliary seal effect; Cylindrical compression spring 8 tops are contained in intake pipe 6 and adjust between the swivel nut 9, and the interface pressure between auto-compensation arc outer spherical surface 13 and the arc inner ball surface 14 is by the position of round nut 10 locking adjustment swivel nuts 9; Described intake pipe 6 belows are provided with pin 11, make intake pipe 6 vertical motion and can not rotating in adjusting the straight trough of swivel nut 9; Described housing 4 is provided with anti-turn bolt 12, prevents that with the equipment connection that uses housing 4 from rotating during installation; Be connected with socket head screw 5 between described bearing support 2 and the housing 4; Described intake pipe 6 one ends are arc outer spherical surface 13, and described outlet pipe 1 one ends are arc inner ball surface 14, arc outer spherical surface 13 sealing that contacts with arc inner ball surface 14, and arc outer spherical surface 13 and arc inner ball surface 14 be tangent to have the self-aligning seal action.
During use, intake pipe 6 one ends link to each other with mortar pump, outlet pipe 1 one ends link to each other with the use machine spindle, grinding mortar enters in the intake pipe 6, intake pipe 6 vertical motion and can not rotating in adjusting the straight trough of swivel nut 9 grinds mortar to flow into subsequently in the outlet pipe 1, and outlet pipe 1 rotates with the use machine spindle, discharge finally by outlet pipe 1, realize grinding mortar and enter machining area.
