Description
Technical field
The present invention is a kind of device and method detecting disc tool magazine turntable indexing accuracy, belongs to Digit Control Machine Tool function zero
Component capabilities detection field.
Background technology
Tool magazine and automatic tool changer are the important component parts of numerical control machining center, are to have deposit Cutters In Mc
And the key feature of automatic tool changer function, including tool magazine and mechanical hand two parts.Tool magazine and automatic tool changer tool changing
Journey is broadly divided into selects cutter and tool changing two parts: tool magazine instructs accurate for the broach shell at required cutter place according to what control system sent
Deliver to tool change position；Required cutter and main shaft are fixed a cutting tool and are swapped by automatic tool changer.The kind of tool magazine is a lot, common
Have bamboo hat type tool holder, magazine and disc tool magazine.Disc tool magazine is used primarily in middle-size and small-size vertical machining centre, main portion
Part is tool magazine body, indexing rotary table and tool-changing mechanical arm.Tool magazine, during selecting cutter, drives indexing cambered surface convex by servomotor
Wheel rotates, and then drives the roller on indexing rotary table to rotate, indirectly controls rotating disk and select cutter, and turntable rotation is by needed for next process
Tool change position delivered to accurately by cutter.Tool magazine is after long time running, due to servomotor, limb face cam and the mistake of rotating disk
Difference-product tires out, and can directly affect accuracy and the reliability of tool magazine automatic tool changer, seriously may cause hitting cutter, falling cutter, even lathe
The phenomenons such as damage occur.So the indexing accuracy of detection rotating disk is necessary, this will assist in raising tool magazine and adds
The reliability that work center is overall.
Summary of the invention
The indexing rotary table of tool magazine, during selecting cutter, carries out rotation around central shaft, senses installing detection encoder
Device has certain difficulty, needs to design a set of the most complete but also uncomplicated test apparatus and method.
A kind of device detecting disc tool magazine turntable indexing accuracy, comprises two parts, and a part is this body structure of tool magazine,
Another part is the device of design on this body structure of tool magazine.Part I this body structure of tool magazine is tool magazine body 1, at tool magazine originally
Fixing axle on body 1, equipped with bearing 4 on fixing axle, bearing outer ring and indexing rotary table 2 are fixed, and such indexing rotary table 2 can lead to
Crossing rotation to complete to select cutter action, this is this body structure of tool magazine.It is characterized in that: the apparatus structure of design on this body structure of tool magazine
For: owing to tool magazine body is fixed, therefore connecting shaft 6 is fixed male thread through bearing (ball) cover 5 with tool magazine body and is connected.
Turntable shaft 7 is bolted on indexing rotary table 2, and connecting shaft 6 is through the central through hole of turntable shaft 7.Encoder 8 inner ring with turn
Dish axle interference fit, outer ring is bolted with fixed plate 9, and fixed plate 9 nut is fixed on connecting shaft 6 end.
A kind of method of device detecting disc tool magazine turntable indexing accuracy, connecting shaft 6 one end and encoder outer ring phase
Even, turntable shaft 7 is connected with encoder inner ring.Owing to connecting shaft 6 other end is connected with tool magazine body 1, so tool magazine indexing rotary table 2
In rotation process, connecting shaft 6 is fixed, i.e. encoder outer ring is fixed, but turntable shaft 7 is as point
Degree rotating disk rotates and rotates, so encoder outer ring is as what indexing rotary table 2 rotated together, such encoder 8 can be examined
Measuring indexing signal, encoder inner ring rotates a circle and sends the semaphore of fixed qty.Signal is received with capture card 10, and phase
Answer data to send PC 11 to, pass through collected data, calculate the error of division of indexing rotary table.
Process screw thread on the axle of connecting shaft 6 rear end, replace tool magazine itself for the bolt of fixed bearing end lid 5.
It is an advantage of the current invention that:
(1) the invention provides a kind of device and method detecting disc tool magazine turntable indexing accuracy, can be exactly
Detect indexing accuracy during magazine knife-selecting, can be that research disc tool magazine reliability provides experimental basis；
(2) in the device designed by the present invention, dexterously by means of this body structure of tool magazine, connecting shaft is with machine body even
Connect, it is ensured that maintain static so that detection test structure parts are easy and be easily installed and dismantle；
(3) present invention is used for detecting indexing accuracy, detects by High Precision Absolute Encoder, through calculating, turns
Changing displacement error into, its precision can reach micron order, substantially increases the referring to property of result of the test.
(5) present invention is through it is demonstrated experimentally that designed plant running is stable, it is ensured that experimental facilities is long playing can
By property and the accuracy of data, provide laboratory reference data accurately for tool magazine manufacturer.
