Description
Technical field
Patent of the present invention is related to a kind of lathe or grinding machine automatic fixture, specifically a kind of bent axle automatic indexing hydraulic clip
Tool.
Background technology
At present, as China's ship, auto industry develop rapidly, demand of the engine production factory to engine crankshaft
Increase swift and violent.But China is in terms of Crankshaft Machining still in relative backward state, especially automobile, heavy truck, small diesel engine
The processing technology in crankshaft-link rod footpath, is even more in a backward condition.Such as heavy truck bent axle, three sets of manuals are mainly made,
1-6,2-5,3-4 are corresponded to respectively per sleeve clamp turns footpath, point another processing on three lathes, by the clamping three times of fixture and positioning
Conversion could be completed to clamp and process, which results in the processing efficiency of bent axle is low, connecting rod footpath process to parallactic angle and eccentric throw
Error is significantly increased, Crankshaft Machining low precision, so, the performance of engine is well below the hair that external advanced manufacturer manufactures
Motivation.
The content of the invention
In order to solve the processing efficiency of bent axle in the prior art is low, the processing of connecting rod footpath to parallactic angle and eccentric throw error it is big,
The shortcomings that Crankshaft Machining low precision and deficiency, the present invention program provide a kind of bent axle automatic indexing hydraulically operated fixture.Including with machine
The specific assembly of fore-clamp that bed main shaft coordinates and the rear jig body assembly with tailstock tool cooperation, the specific assembly of fore-clamp include being used to pacify
The forward spindle of bent axle is filled, is arranged on by bearing on forward spindle and the fore-clamp that is rotated on forward spindle is specific, and can be by liquid
Force feed is transported to fore-clamp and specifically turns round Oil-pressure joint and before award beam hanger；The specific assembly of fore-clamp and rear jig body assembly structure phase
Together.
Further, the installation of forward spindle interior hollow section, which is provided with clamping bent axle clamping force, steps up oil cylinder, steps up oil
Cylinder is connected by hinge arms, power transmission shaft with clamp jaw.
Further, forward spindle rear end is provided with precision indexing fluted disc and brambles wheel, and indexing positional cylinder insertion is installed on
In precision indexing fluted disc.
Further, forward spindle is stirred by swing arm and rotated together with index cylinder, bent axle.
Further, T-slot is carried on forward spindle, the T-slot that forward spindle is locked by locking cylinder driving lock shaft can
Forward spindle is fixed and locked.
Further, the anglec of rotation of bent axle is by rotating distance adjusting screw and stroke adjustmenting screw, to indexing oil
Cylinder carries out Traffic control system and adjusted.
The principle of technical solution of the present invention is：A kind of bent axle automatic indexing hydraulically operated fixture, fixture include pre-eccentric indexing folder
Tool and rear eccentric fixture two parts composition.Crankshaft installed is positioned between two sets of part fixtures with crankshaft two end main shaft diameter.It is preceding inclined
Heart indexing fixture is mainly realized to bent axle to be clamped, indexes, positioning, locking.It is by Driven by Hydraulic Cylinder hinge booster that bent axle, which clamps,
Mechanism, two claw synchronous rotaries of tape spool, clamp bent axle.Bent axle indexing is by Driven by Hydraulic Cylinder chaste tree ratchet mechanism, is often acted
One time one direction rotates a certain angle, so as to realize bent axle to parallactic angle coarse positioning.Positioning is to index tooth by Driven by Hydraulic Cylinder,
Insertion indexing tooth corresponding to precision index plate realizes the high accuracy positioning to bent axle indexing.Locking is locked by Driven by Hydraulic Cylinder
Bar, by locking of the T-slot to rotary part, no longer it is moved after ensureing bent axle indexing positioning.Eccentric fixture only presss from both sides afterwards
Tight and locking function, the same front jig of structure, realized by bent front jig during indexing.
It is can be seen that from above-mentioned processing method according to the present invention, using front and rear two parts fixture, clamped one time realizes bent axle
Connecting rod footpath full-automatic processing, machining accuracy was both improved and has also improved processing efficiency.Clamping, indexing of the fixture to bent axle are fixed
Position, locking use hydraulic-driven, and can realize Automatic Control.
Compared to the prior art, the beneficial effect of the present invention program is：
1. clamping, indexing positioning, locking of the hydraulically operated fixture to bent axle use hydraulic-driven, digital control system pair can be passed through
Hydraulic system is programmed control, realizes Automatic Control, has both improved machining accuracy and has also improved processing efficiency；
2. the structure of this structure design, have the advantages that to clamp firm, automatic indexing, precision positioning, automatically control, more
It is important that clamped one time, clamping unifying datum, thus be not in because of extra error caused by clamping twice, so as to improve
Crankshaft-link rod footpath to parallactic angle and eccentric throw machining accuracy.

Embodiment
With reference to Fig. 1-5, the present invention will be described in detail, with the design feature and application method of the clear and definite present invention.
A kind of bent axle automatic indexing hydraulically operated fixture, bent axle 5 are arranged between front and rear fixture, and radial positioning is carried out by main shaft
Clamping cylinder 10 afterwards, it is connected by hinge arms 11 and power transmission shaft 12 with clamp jaw 19, and drives clamp jaw 19 to press from both sides bent axle
Tightly, above parts are mounted on forward spindle 4.
Forward spindle 4 is arranged on fore-clamp specific 3 by bearing 18, can the rotary motion on fore-clamp specific 3.After forward spindle 4
End is provided with precision indexing fluted disc 14 and brambles wheel 15, and index cylinder 22 stirs forward spindle 4 by swing arm 23 and bent axle 5 together revolves
Turn.The stroke of index cylinder 22 is adjusted by stroke adjustmenting screw 21 and stroke adjustmenting screw 24, so as to adjust the rotation of bent axle 5
Angle.Index positional cylinder 13 and insert precision indexing fluted disc 14, realize that bent axle is accurately positioned.Locking cylinder 16, driving lock shaft
17, the T-slot of forward spindle 4 is locked, so as to which forward spindle 4 is fixed into locking.
Main shaft 6 is equally arranged on rear jig body 7 with front end afterwards, and locking action is identical.Front and rear fixture hydraulic oil passes through
Oil-pressure joint 1 and revolution Oil-pressure joint 9 are turned round, beam hanger 8 is awarded with after by preceding awarding beam hanger 2, is transported to fore-clamp specific 3 and rear jig
On body 7, and supply each oil cylinder.
It is can be seen that from above-mentioned specific embodiment according to the present invention, clamping, indexing of the fixture to bent axle position, lock
Hydraulic-driven is tightly used, and Automatic Control can be realized, using front and rear two parts fixture, clamped one time realizes crankshaft-link rod
Footpath full-automatic processing, machining accuracy was both improved and has also improved processing efficiency.
The structure of this structure design, have the advantages that to clamp firm, automatic indexing, precision positioning, automatically control, it is heavier
What is wanted is clamped one time, clamping unifying datum, thus is not in because of extra error caused by clamping twice, so as to improve song
Axle connecting rod footpath to parallactic angle and eccentric throw machining accuracy.
The above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to preferred embodiment to this hair
It is bright to be described in detail, it will be understood by those within the art that, technical scheme can be modified
Or equivalent substitution, without departing from the objective and scope of technical solution of the present invention, it all should cover the claim in the present invention
Among scope.
