Description
Technical field
The present invention relates to pipeline docking technique field, specially a kind of precision equipment pipeline docks centring means.
Background technique
The case where pipeline docking can be all encountered in the fields such as road construction or the manufacturing, in order to guarantee that pipeline docks matter
Amount, workpeople can ensure that two pipelines are located on same center line using centrescope.
Traditional centrescope makes through the identical spring of four elastic force of installation outside a casing, a jaws which come into abutting of spring,
After being inserted into pipeline, pipeline surrounding can so be played certralizing ability by identical thrust.
When carrying out the docking of some high precision pipelines, it is self-possessed since pipeline exists, leads to the spring below pipeline
While by piping reaction, the gravity of pipeline is also suffered from, error may be caused to centering result in this way, influenced
Effect is docked, therefore we have proposed a kind of precision equipment pipeline docking centring means to solve the problems, such as.
Summary of the invention
In view of the above-mentioned problems, the purpose of the present invention is to provide a kind of precision equipment pipelines to dock centring means, there is essence
The high effect of density.
The present invention is to realize that technical purpose adopts the following technical scheme that a kind of precision equipment pipeline docks centring means, packet
Shell is included, the outside of the shell is interspersed to be provided with eight position-limiting tubes, and four are symmetric for one group, the position-limiting tube
Top is welded with platen, offers the opening communicated with position-limiting tube at the top of platen, and the lower rotation of the platen is connected with turntable,
Turntable is annular in shape.
The bottom of the turntable offers bayonet, and the bottom of the platen offers loose slot, the loose slot and bayonet
It is overlapped, movable block is plugged in the loose slot, viscous stick in the bottom of the movable block has centering spring, and centering spring is located at limit
The two sides of pipe.
The inner wall side of the position-limiting tube offers multiple groups regulating tank, the regulating tank bilateral symmetry, the top of the platen
It is plugged with the mandril extended in position-limiting tube, slot is offered at the top of the mandril, the inner bottom wall of the slot is stained with multiple
Position spring, viscous stick in the top of the reset spring have the adjusting rod extended to outside slot, and the two sides of the adjusting rod offer
Compression groove, glue in the compression groove it is glutinous have compressed spring, the length of compressed spring and the depth of compression groove are identical, the mandril
Two sides are interspersed to be provided with the kelly extended in slot, and viscous stick in the bottom of the mandril has tune to have section spring.
Viscous stick in the bottom of the adjustment spring has link block, and the bottom of the link block is welded with fixture block, the fixture block
Lower rotation is connected with idler wheel.
As optimization, the compression groove is located at the top of kelly, and the distance between it is long with the maximum collapse of reset spring
Spend identical, the depth of compression groove is greater than the depth of regulating tank, and the kelly and adjusting rod are in close contact, and kelly is located in regulating tank
Part be curved surface.
As optimization, it is provided with latch on the inside of the bayonet, is provided on the outside of the movable block corresponding with latch
Card slot, the elastic force of the adjustment spring are less than the elastic force of centering spring.
As optimization, the elastic force of centering spring and the reset spring up and down is all different, the regulating tank be it is round table-like,
The width of the link block is greater than the diameter of position-limiting tube.
As optimization, the movable block is made of lighter material.
As optimization, the elastic force of the upper and lower centering spring and reset spring is all different, because each component has self weight,
It is compressive state when causing top spring initial, is tensional state when lower section spring is initial, makes spring stress difference up and down, therefore
It, need to be according to the spring of installation position selection difference elastic force, to offset each component effect of weight when spring is installed.
The present invention have it is following the utility model has the advantages that
1, the precision equipment pipeline docks centring means, by the installation and adjustment spring between mandril and link block, uses
When, adjusting rod is pressed into slot, compression groove and kelly are in same level height at this time, press mandril still further below, so block
Bar with mandril it is mobile when, be pressed into compression groove by curved surface, according to the model of docking pipeline, mandril be moved to using position
It sets.
Adjusting rod is decontroled, adjusting rod is resetted by reset spring, and compression groove is separated with kelly, and kelly can not move again, this
Sample is fixed mandril by kelly, and such mandril compression adjustment spring gives link block one pre-applied force, offsets the self weight of pipeline, this
Sample reduces the error of centering, ensure that the quality of product.
2, the precision equipment pipeline docks centring means, by the installation activity block between platen and centering spring, applies
Before pre-applied force, turntable is first rotated, bayonet inside latch is made to leave the card slot on the outside of movable block, movable block unlock, since power has
Relativity, mandril will receive a reversed thrust when applying pre-applied force, in this way by a movable block connection, make this reaction
It can not act on centering spring, make centering spring that can be always maintained at original state, improve the accuracy of centering.
