Description
Technical field
The present invention relates to truss manipulator fields, particularly relate to a kind of inclined wedge traveller centering machine.
Background technique
Medium-sized cover parts are such as driven a vehicle wheel, also known as " crown sheave ", are the key parts of crane.Driving wheel volume is larger,
Heavier mass, outer diameter is that the driving wheel of 300mm weighs 40 kilograms, if by artificial loading and unloading, large labor intensity expends working hour
It is more, especially in batch production, it will seriously restrict production efficiency.Therefore driving wheel automatic assembly line selects truss manipulator real
Existing automatic loading/unloading reduces production cost to improve productivity.
Even if the truss manipulator of high-precision grade, when its is specified grabs again more than 63 kilograms, repetitive positioning accuracy is logical
Often ± 0.1 or more, and row wheel inner holes are interference fitted because being formed with bearing, and inner hole geometric accuracy is higher, if therefore with
Traditional rigid central spindle's positioning, manipulator necessarily will appear in feeding blanking process can not accurate workpiece loading and unloading the problem of.
Therefore, for driving wheel class volume and the biggish cover parts of quality, Eco-power truss manipulator is fully considered
Certain resetting error should be stayed a certain amount of adaptable with manipulator repetitive positioning accuracy between positioning core axle and location hole
Loading and unloading gap, i.e., manipulator handling driving wheel when, mandrel be returned between reset condition and row wheel inner holes there are
Gap is loaded and unloaded in which can be convenient；When lathe clamps driving wheel processing, mandrel expansion, between eliminating between mandrel and row wheel inner holes
Gap is accurately positioned.
Currently used fluidity medium centering mandrel makes elasticity using liquid plastics and oil liquid as the medium of transmitting pressure
Thin walled cylinder body generates uniform radial deformation, eliminates the gap between workpiece and sleeve, thus make workpiece accurately felt relieved and
It clamps, it is ensured that concentricity is a kind of very high fixture of centering precision within ￠ 0.02.But it is some special that such fixture has
Point: (1) plastic medium needs particular arrangement, and when casting must preheat.Oil liquid medium is then more demanding to sealing performance；(2) fixture
Structure is complicated, and elastic element calculates and machining accuracy is high, at high cost；(3) deflection of elastic element is smaller (0.003D), such as hole
Its diametric swell increment of diameter 150mm is only ± 0.045, and the workpiece big to tolerance variation range is then difficult to ensure reliable folder
Tight and tradition；(4) when workpiece positioning surface length is longer, the deformation of the thin walled cylinder body as elastic element is uneven, will cause
The positioning of workpiece is unstable；(5) liquid plastics are easy to aging, oil liquid medium easy to leak, cause fixture management and maintenance complicated.
Summary of the invention
The present invention to solve problems of the prior art, proposes a kind of inclined wedge traveller centering machine.
The technical scheme of the present invention is realized as follows:
A kind of inclined wedge traveller centering machine, composition include: the centering machine being mounted in workpiece, and the centering machine includes drawing
Bar, piston rod, tapered wedges, nut, sliding block, positioning sleeve, abrasive rubber block, workbench, ring flange, the pull rod upper end pass through institute
It states tapered wedges and is connected by the nut, the pull rod lower end is connect with the piston rod thread, and the tapered wedges are mounted on
In the positioning sleeve, the sliding block is arranged on the positioning sleeve, and the sliding block is stuck on the outer wall of the tapered wedges, described
Slip front is additionally provided with abrasive rubber block, contacts on the outside of the abrasive rubber block with the workpiece, the positioning sleeve is mounted on institute
It states on platen, the lower surface of the platen and the ring flange of hydraulic cylinder are fixed.
Positioning sleeve is made of the sleeve and positioning plate positioned at lower end for being located at upper end, set in the sleeve lateral wall there are three
The sliding block is arranged in slot at the slot.
The diameter of the tapered wedges gradually becomes smaller from top to bottom, set on the outer wall of the tapered wedges there are three with the slot
Corresponding skewed slot, the sliding block are stuck in the skewed slot.
The piston rod is the piston rod of the hydraulic cylinder, and the piston rod provides power for the centering machine.
The beneficial effects of the present invention are: the present invention becomes fixture more flexibly by interchangeable tapered wedges and sliding block
Property；
2. the clamping diameter that the present invention is suitable for workpiece is bigger, the shorter and corresponding machining tolerance of clamping length is bigger
In the case of, it is especially used for the machine tool of manipulator automatic charging, the positioning accurate of manipulator loading and unloading can be lowered significantly
Degree requires, and Design of Production Line cost is effectively reduced.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is sectional view along A-A of the invention；
Fig. 3 is B-B direction cross-sectional view of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under that premise of not paying creative labor
