Background technology
Bent axle is one of most unmanageable core part of internal combustion engine, when processing it on crank-shaft link neck digital control lathe clamper
During connecting rod neck, first bent axle angularly must be positioned before processing, so as to ensure the uniformity at crank-shaft link neck phase angle.It is existing
A disc side on bent axle is used to be used as angular locating surface in feeding in the angular positioning of most bent axles
Positioning manually is close to, is wasted time and energy, and deviation easily occurs, so as to influence phase accuracy.
The content of the invention
The purpose of this utility model is to provide a kind of angular positioning gas chuck structure for crank-shaft link neck numerically controlled lathe,
Self-centering clamping is carried out to connecting rod neck, so as to realize the angular positioning to bent axle.
This angular positioning gas chuck structure for crank-shaft link neck numerically controlled lathe, pressed from both sides in crank-shaft link neck numerically controlled lathe
A set of clamp body is respectively installed before tool left and right main spindle box, it is characterised in that cylinder is placed on two triangle frame bases of angular positioning seat,
Two clamping jaw shrinkage pools are relatively fixed on two dog chucks, and screw thread, which screws, between two dog chuck bottoms and cylinder connects；Wedge
The right angle in angular positioning seat swash plate bottom fin is squeezed, for adjusting the clamping center of clamping jaw, it is a set of angular fixed thus to form
Position gas chuck structure；A whole set of gas chuck assembly is fallen on lathe bed, between the fixture of left and right, clamping jaw is located at will adding for bent axle
The transmission bar of lathe is worn between the connecting rod neck of work, in shrinkage pool；Cylinder on gas chuck structure is wherein ventilated all the way, two dog chucks
It will be clamped with two clamping jaws to centre, when clamping the connecting rod neck of workpiece bent axle, the now center of crank-shaft link neck and master
The axle centre of gyration is consistent, that is, realizes the angular positioning to bent axle；Swash plate after adjustment is consistent by pressing plate angular positioning seat
Locked with lathe bed bolt.
For ensure processing crank-shaft link neck center it is consistent with the centre of gyration of main spindle box, machining crankshafts connecting rod neck it
Before bent axle must angularly be positioned.The design realizes gas chuck pair using on crank-shaft link neck digital control lathe clamper
The angular positioning of crank-shaft link neck, cylinder dominate angle and can be organized in machine tooling program to positioning self-locking operation, added
Changing workpiece in engineering sequence every time, just automatic running angularly positions, and so as to no longer be close to positioning with manpower, and has saved the time, together
When clamping jaw self-centering clamping improve positioning precision than artificial be close to.
Brief description of the drawings
Fig. 1 is angular positioning gas chuck outline structural diagram；
Fig. 2 is the location drawing of the angular positioning gas chuck in crank-shaft link neck digital control lathe clamper.
Embodiment
This angular positioning gas chuck structure for crank-shaft link neck numerically controlled lathe of the design, it is characterised in that described
Angular positioning gas chuck structure, is shown in Fig. 1, cylinder 2 is placed on two triangle frame bases of angular positioning seat 1, two shrinkage pool phases of clamping jaw 4
To being fixed on above two dog chucks 3, the bottom of two dog chuck 3 is arranged on the cylinder 2 between two triangle frames of angular positioning seat 1,
And screw thread is screwed and connected between the dog chuck 3 of cylinder 2 and two；Wedge 11 squeezes the right angle in the angular swash plate bottom fin of positioning seat 1
Place, for adjusting the clamping center of clamping jaw 4, the swash plate of angular positioning seat 1 is locked by pressing plate 5 and the bolt of lathe bed 6, thus formed
A set of angular positioning gas chuck structure.
Mounting structure：The fixture of crank-shaft link neck numerically controlled lathe is to install one respectively on left main spindle box 7 and right main spindle box 8
Sleeve clamp body 9, is shown in Fig. 2, and a whole set of gas chuck structure is fallen on lathe bed 6, between two clamp bodies 9, above gas chuck
Clamping jaw 4 is located between the connecting rod neck that will be processed of bent axle 10.The opposite thread of the dog chuck 3 of cylinder 2 and two is screwed and connected,
After the main shaft rotation center adjustment unanimously for clamping center and crank connecting rod journal lathe of gas chuck upper gripper jaw 4, then it is logical with pressing plate 5
Bolt is crossed to lock gas chuck structure and lathe bed 6.Cylinder 2 on gas chuck structure is wherein ventilated all the way, two dog chucks 3 will
Clamped with two clamping jaws 4 to centre, when clamping the connecting rod neck of workpiece bent axle 10, the now center of crank-shaft link neck and main shaft
The centre of gyration is consistent, that is, realizes the angular positioning to bent axle.Cylinder dominates angle can be organized in machine to positioning self-locking operation
In tool machining program, with workpiece is changed in procedure, automatic running angularly positions.
The dog chuck 3 of cylinder 2 and two on gas chuck structure is outsourcing piece, respectively has screw thread, and cooperate and screw.Its
Middle cylinder 2 is equipped with two paths, after workpiece bent axle 10 machines, connects another path, and clamping jaw 4 is retracted, angular positioning
