Description
Technical field
The present invention relates to a kind of fixture, for clamping elongated isomery tap on automatic polishing machine, belonging to part polishing field of mechanical technique.
Background technology
All kinds of tap is widely used in public place and private residence.The manufacture of tap will pass through the processing steps such as casting, tapping, emery wheel polishing, buffing.And the work of polishing is at present mainly by what manually come, this has brought heavy manual labor to workman, also reduces the efficiency of production.Use automatic polishing machine can effectively alleviate artificial burden, greatly enhance productivity, but automatic polishing machine needs 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 " a kind of stationary fixture of faucet handle positioning welding ", the fixture of this kind of secure faucets is applicable to welding procedure, and be the outer surface of product due to glossing processing, be not therefore suitable for polishing machine.
CN201220266363.6 discloses " a kind of tap clamping device ", this holder be three mouths (water inlet, delivery port and spool installing hole) of tap, this method of clamping no longer can clamp outer surface, facilitates the processing of polishing to a certain extent.But its all fixture group is all fixed on one piece of fixed head, during the another side of converted products, need clamping again, and add and there is processing dead angle man-hour.
CN201110454457.6 discloses one " internal expansion type fixture for faucet ", this fixture by arranging elastic expansion-sleeve on thimble front end, after elastic expansion-sleeve being stretched into tap endoporus, thimble pushes forward or draws back backward, make elastic expansion-sleeve even inflation or be returned to reset condition, tensioner or unclamp endoporus, namely completes the crawl of tap or places action.The clamp structure of this employing internal expansion type clamping tap endoporus, solve tap outer surface well and clamped the problem of inconvenient polishing, but fixed by frictional force between its elastic expansion-sleeve and tap endoporus, the clamping dynamics of frictional force is limited after all, for may be comparatively applicable miniature water tap, for then inapplicable elongated isomery tap.
In the industry cycle, elongated isomery tap refers to the tap with the unconventional shape comparatively growing water pipe, as shown in Figure 6, a screwed hole 91 is typically provided with on rear side of the water inlet end of this kind of tap 9, or water inlet stomidium in be provided with one install annular groove 92, and between water inlet end and water side stair-stepping water stream channel 93.The outlet pipe of this kind of tap is very long, and is arranged on side, forms a kind of top-heavy state, therefore adopts the internal expansion type fixture disclosed in above-mentioned CN201110454457.6, only relies on frictional force to fix, obviously can not be suitable for.
Summary of the invention
Technical problem to be solved by this invention is the requirement of the architectural feature for automatic polishing machine cylinder switching part and elongated isomery tap, provides a kind of fixture being exclusively used in this automatic polishing machine and tap.
For solving the problems of the technologies described above, technical solution of the present invention is:
A self-centering fixture for isomery tap, comprises jaw, guiding parts, pivoting part, switching part, shell and actuating unit; Described jaw at least arranges three, and the below of each jaw is provided with a slide bar, lateral surface be provided with locating piece with fix tap water inlet stomidium in annular groove or step structure place; This guiding parts is at least provided with three gathering sills according to the quantity of jaw, and this gathering sill is centripetal radial arrangement, and described slide bar is through this gathering sill; This pivoting part is provided with at least three chutes, and described slide bar end is through this chute; The below of this pivoting part is provided with axostylus axostyle, and this axostylus axostyle is provided with horizontal sliding pin; This switching part is connected with described actuating unit, is provided with coulisse above it, and this coulisse is provided with the sliding tray be obliquely installed, and the end of described sliding pin is through this sliding tray; This shell is for installing guiding parts, pivoting part and switching part; This actuating unit drives described switching part to move up and down.
Preferably, described jaw is provided with three, and wherein two is long jaw, and one is short jaw; The locating piece of two long jaws withstands in the water stream channel of tap water inlet end internal step scalariform, and the locating piece of short jaw is provided with locating dowel, inserts in the screwed hole of tap during this locating dowel location.
Preferably, described slide bar and jaw is one-body molded is set together, or both are by thread locking together.
Preferably, described slide bar is fixed with ball slider, by this ball slider slippage in described gathering sill.
Preferably, be provided with ball slider guide groove in described guiding parts, described ball slider is positioned at this ball slider guide groove, and it is provided with ball in four sides up and down; This guiding parts is made up of base and top cover, and this ball slider guide groove is arranged between this base and top cover.
Preferably, described slide bar end is connected by the chute of bearing with described pivoting part.
Preferably, ball is equipped with in top and the below of described pivoting part, be positioned at top ball withstand on described guiding parts, be positioned at below ball withstand on be arranged on described shell dividing plate on.
Preferably, described side wall of outer shell has transom window.
Preferably, the hole that the axostylus axostyle of described pivoting part can be made deep is provided with in the middle part of described switching part.
Preferably, described pivoting part can drive each slide bar to do centripetal rectilinear motion along gathering sill, be fixed on jaw on each slide bar and outwards open simultaneously, and the power of opening is identical, automatic centering when making tap clamping, thus makes tap and fixture on the same axis.
After adopting such scheme, due to the present invention, to devise one be the pivoting part of gyration by the transform linear motion of polishing machine cylinder and gyration is converted into the guiding parts of the centripetal motion of jaw, the power that polishing machine cylinder upwards pushes up can be converted into the power that jaw opens, and can regain along the track opened at the rear clip-claw of cylinder falling, conveniently fix and take off tap.What adopt due to the present invention is a kind of mechanism of similar three-jaw self-centering chuck, and three-jaw outwards opens simultaneously, and the clamping force of each jaw is identical, can ensure the automatic centering when installing tap.Three-jaw, from the clamping of tap inside, also can not have influence on the polishing of tap outer surface.And in polishing process, tap can be subject to the power of all directions, the structure of three-jaw can good secure faucets, does not allow tap produce the deviation of position because of stressed.In a word, this fixture can be applicable to for clamping the instrument of a elongated isomery tap on a certain automatic polishing machine, and this fixture can fix this tap effectively, and locates accurately, is convenient to the work of this polishing machine.But theoretically, this fixture also can be applicable to the axle sleeve structure workpiece of the overwhelming majority from inside clamping.
