Description
Technical field
The present invention relates to a kind of fixture, for clamping elongated isomery tap on automatic polishing machine, belongs to part polishing
Field of mechanical technique.
Background technology
All kinds of taps are widely used in public place and private residence.The manufacture of tap will pass through casting, tapping,
The processing steps such as emery wheel polishing, buffing.And the work polished at present is mainly by manually come what is completed, this brings to worker
Heavy manual labor, also reduce the efficiency of production.Artificial burden can effectively be mitigated using automatic polishing machine, significantly
Production efficiency is improved, but automatic polishing machine is needed for the special fixture of each Element Design.
As a rule, the use of fixture is all the outer surface of product clamping, such as CN201320664642.2 discloses " one
The stationary fixture of kind faucet handle positioning welding ", the fixture of this kind of secure faucets are applied to welding procedure, and due to throwing
The processing of light technique is the outer surface of product, therefore is not suitable for polishing machine.
CN201220266363.6 is disclosed " a kind of tap clamping device ", and that the fixture clamps is three of tap
Mouth (water inlet, delivery port and valve element mounting hole), this method of clamping can no longer clamp outer surface, facilitate to a certain extent
The processing of polishing.Needed but its all fixture group is all integrally fixed in one piece of fixed plate, during the another side of converted products
Again clamping, and processing dead angle during processing be present.
CN201110454457.6 discloses a kind of " internal expansion type fixture for faucet ", and the fixture on thimble front end by setting
Elastic expansion-sleeve is put, after elastic expansion-sleeve is stretched into tap endoporus, thimble is pushed forward or drawn back backward, makes elastic expansion-sleeve uniformly swollen
It is swollen or be returned to reset condition, tensioner or endoporus is unclamped, that is, complete crawl or placement action to tap.In this use
The formula that rises clamps the clamp structure of tap endoporus, solves tap outer surface well and is clamped asking for inconvenient polishing
Topic, but between its elastic expansion-sleeve and tap endoporus fixed by frictional force, the clamping dynamics of frictional force is limited after all,
It may more be applicable for small-sized tap, do not applied to then for elongated isomery tap.
In the industry cycle, elongated isomery tap refers to the tap of the unconventional shape with longer outlet pipe, such as Fig. 6 institutes
Show, a screwed hole 91 is typically provided with rear side of the water inlet end of this kind of tap 9, or a mounting ring is provided with water inlet stomidium
Groove 92, and stair-stepping water stream channel 93 is set between water inlet end and water side.The outlet pipe of this kind of tap is very long, and
And side is arranged on, a kind of top-heavy state is formed, therefore using the internal expanding disclosed in above-mentioned CN201110454457.6
Formula fixture, only rely on frictional force and fix, it is clear that can not be applicable.
The content of the invention
The technical problems to be solved by the invention are to be directed to automatic polishing machine cylinder switching part and the elongated isomery fire hose
A kind of requirement of the architectural feature of head, there is provided fixture for being exclusively used in the automatic polishing machine and tap.
In order to solve the above technical problems, the technical solution of the present invention is：
A kind of self-centering fixture of isomery tap, including clamping jaw, guiding parts, pivoting part, switching part, shell with
And actuating unit；For the clamping jaw at least provided with three, the lower section of each clamping jaw is provided with a slide bar, lateral surface be provided with locating piece with
Fix at the annular groove or step structure in tap water inlet stomidium；The guiding parts according to the quantity of clamping jaw at least provided with
Three guide grooves, the guide groove are centripetal radial arrangement, and the slide bar passes through the guide groove；The pivoting part is provided with least
Three chutes, described slide bar end pass through the chute；The lower section of the pivoting part is provided with axostylus axostyle, and the axostylus axostyle is provided with horizontal
Sliding pin；The switching part is connected with described actuating unit, and its top is provided with coulisse, and the coulisse is provided with and is obliquely installed
Sliding groove, the end of the sliding pin passes through the sliding groove；The shell is used to install guiding parts, pivoting part and switching
Part；The actuating unit drives the switching part to move up and down.
Preferably, the clamping jaw is provided with three, and two of which is long clamping jaw, and one is short clamping jaw；Two long clamping jaws
Locating piece is withstood in the water stream channel of tap water inlet end internal step scalariform, and the locating piece of short clamping jaw is provided with locating dowel, and this is fixed
Inserted in during the post positioning of position in the screwed hole of tap.
Preferably, described slide bar is integrally formed with clamping jaw is set together, or both together with by thread locking.
Preferably, ball slider is fixed with described slide bar, by ball slider sliding in described guide groove.
Preferably, ball slider guide groove is provided with described guiding parts, the ball slider is located at the ball slider
In guide groove, it is provided with ball on four sides up and down；The guiding parts is made up of base and top cover, and the ball slider guide groove is set

Preferably, described slide bar end is connected by bearing with the chute of the pivoting part.
Preferably, the pivoting part is equipped with ball over and under, and ball above withstands on the guide part
On part, underlying ball is withstood on the dividing plate being arranged in the shell.
Preferably, described side wall of outer shell is provided with transom window.
Preferably, the deep hole of the axostylus axostyle of the pivoting part can be made by being provided with the middle part of described switching part.
Preferably, the pivoting part can drive each slide bar to do centripetal linear motion along guide groove, be fixed on each slide bar
Clamping jaw be flared out simultaneously, and the power opened is identical, automatic centering when making tap clamping, so that tap and fixture
On the same axis.
After such scheme, transported because the present invention devises a transform linear motion by polishing machine cylinder for revolution
Dynamic pivoting part and the guiding parts that gyration is converted into the centripetal motion of clamping jaw, can push up polishing machine cylinder upwards
Power is converted into the power of clamping jaw opening, and can be withdrawn in the rear clip-claw of cylinder falling along the track of opening, convenient to fix and take
Lower tap.Because the present invention is flared out using a kind of mechanism of similar three-jaw self-centering chuck, three-jaw simultaneously, and
The clamping force of each clamping jaw is identical, it is ensured that the automatic centering when installing tap.Three-jaw clamps inside tap,
The polishing of tap outer surface is not interfered with yet.And in polishing process, tap can be by the power of all directions, three-jaw
Structure can good secure faucets, do not allow tap to produce the deviation of position because of stress.In a word, this fixture can be applied
In the instrument for being used to clamp a elongated isomery tap on a certain automatic polishing machine, this fixture can effectively fix this water
Tap, and accurately position, it is easy to the work of the polishing machine.However, theoretically, this fixture can also be applied to the overwhelming majority
The axle sleeve structure workpiece clamped from inside.
