Abstract
The sliding shaft sleeve being connected with handwheel is set in a kind of air compressor guide vane switch executive mechanism, including lid, lid, and sliding shaft sleeve is connected with copper nut, screw rod, the crank that the connection of screw rod lower end is connected with guide vane assembly, connecting spring below crank in copper nut, is set；Gland is set between the copper nut upper end and lid.The air compressor guide vane switch executive mechanism that this utility model is provided, by setting gland between copper nut upper end and lid, when stator is closed, pushed down copper nut, upward sliding is prevented, the axial force that screw motion is produced is transmitted to into crank, driven crank to rotate and stator is closed；Simultaneously still crank is held to direction is closed using spring, it is ensured that crank single load bearing all the time, reach elimination screw thread and parts clearance purpose, it is ensured that stator switch is not because screw thread or parts clearance cause to fluctuate during switch.This utility model is by simple transformation, it is ensured that it is flexible accurate that stator is switched, it is ensured that the normal use of air compressor machine.
Description
Technical field
This utility model is related to a kind of air compressor guide vane switch executive mechanism.
Background technology
Air compressor machine is a kind of common gas compressing equipment, and after long-play, stator switch holds general air compressor machine
Inflexible problem is easily switched, to the normal using serious impact is brought of air compressor machine, reason analyzed and is found：Prior art is hollow
Press guide vane actuating mechanism arranges the sliding shaft sleeve being connected with handwheel as shown in figure 1, including lid in lid, sliding shaft sleeve and
Copper nut connects, and screw rod, the crank that the connection of screw rod lower end is connected with guide vane assembly, connecting spring below crank are set in copper nut；
During use, by rotating handwheel, sliding shaft sleeve is driven to rotate, sliding shaft sleeve drives copper nut to rotate, and then screw rod is lifted up,
Crank is pulled to move upwards, stator is opened；Handwheel is rotated backward during closing, spring tension is added, screw rod is moved downward, driven bent
Handle is moved downward, and stator is closed；However, after long-time use, stator rotates dumb or spring fatigue, spring tension can not gram
The stator resistance of motion is taken, and is resulted in screw rod and one piece of copper nut is driven along sliding shaft sleeve upward sliding, and stator is failure to actuate, and produces
Gap is sprung up, causes stator seriously non-linear when closing, caused serious injury and technique fluctuation to air compressor machine.
Utility model content
The purpose of this utility model is that to solve the deficiencies in the prior art and provides a kind of air compressor guide vane switch and hold
Row mechanism.
The purpose of this utility model is realized in the following manner：
The sliding shaft sleeve being connected with handwheel is set in a kind of air compressor guide vane switch executive mechanism, including lid, lid, it is sliding
Moving axis set is connected with copper nut, and screw rod is set in copper nut, and the crank that the connection of screw rod lower end is connected with guide vane assembly connects below crank
Connect spring；Gland is set between the copper nut upper end and lid.
, by bonded sliding shaft sleeve, sliding shaft sleeve is by the bonded copper nut that slides for the handwheel.
The lower spring end is arranged in stator mounting seat.
The air compressor guide vane switch executive mechanism that this utility model is provided, by pressure is set between copper nut upper end and lid
Set, when stator is closed, is pushed down copper nut, is prevented upward sliding, the axial force that screw motion is produced is transmitted to crank, band
Dynamic crank is rotated and closes stator；Simultaneously still crank is held to direction is closed using spring, it is ensured that crank single load bearing all the time,
Reach elimination screw thread and parts clearance purpose, it is ensured that stator switch is not because screw thread or parts clearance cause to fluctuate during switch.This
Utility model is by simple transformation, it is ensured that it is flexible accurate that stator is switched, it is ensured that the normal use of air compressor machine.
Description of the drawings
Fig. 1 is air compressor guide vane switch executive mechanism structural representation in prior art.
Fig. 2 is structural representation of the present utility model.
Specific embodiment
A kind of air compressor guide vane switch executive mechanism, as shown in Fig. 2 including lid 1, lid mounting assembly 2 and base 3,
The sliding shaft sleeve 5 being connected with handwheel 4 is set in lid 1, and handwheel 4 is connected by key 6 with sliding shaft sleeve 5, and sliding shaft sleeve 5 is by sliding
Dynamic key 7 is connected with copper nut 8, sets screw rod 9 in copper nut 8, and 9 upper end of screw rod sets stop nut 11 by split pin 10, under screw rod 9
Then end connects eccentric adjustment 14,14 connecting crank 13 of eccentric adjustment, crank 13 and guide vane assembly through base 3
12 connections, 13 lower section connecting spring 15 of crank, 15 lower end of spring is fixed in stator mounting seat 16；8 upper end of copper nut and lid
Gland 17 is set between body 1, and lower end sets the bearing 18 for reducing friction, and bearing 18 passes through bearing cap 20 and bolt 19 is connected to lid
On 1.
When actuator is used, by rotating handwheel, sliding shaft sleeve is driven to rotate, sliding shaft sleeve drives copper nut to rotate,
Then screw rod is lifted up, and pulls crank to move upwards, and stator is opened, as shown in A in Fig. 2；Handwheel, handss are rotated backward during closing
Wheel drives copper nut to rotate, as gland pushes down copper nut, copper nut cannot upward sliding, copper nut is moved the axial direction for producing
Power is transmitted to crank by screw rod, drives crank to rotate and closes stator, as shown in B in Fig. 2；Simultaneously still using spring to closing side
To holding crank, it is ensured that crank single load bearing all the time, reach elimination screw thread and parts clearance purpose, it is ensured that stator switch not because
Screw thread or parts clearance cause to fluctuate during switch.This utility model is by simple transformation, it is ensured that the flexible standard of stator switch
Really, it is ensured that the normal use of air compressor machine.
Above-described is only preferred implementation of the present utility model, it is noted that for those skilled in the art
For, under the premise of without departing from this utility model general idea, some changes and improvements can also be made, these should also be considered as
Protection domain of the present utility model.
