Description
Technical field
The utility model relates to agitating friction bonding machine bed, specifically, relates to a kind of agitating friction bonding machine bed welding A axle swinging and regulates and stationary device.
Background technology
The agitating friction welding is to move along welding direction after the stirring-head of High Rotation Speed penetrates workpiece, contact site at stirring-head and workpiece produces frictional heat, make that metal forms the plasticity soften layer around it, and realize the Solid-phase welding method that material is connected under the stirring of the stirring-head shaft shoulder and mixing needle and squeezing action.Requiring the plumb joint shaft shoulder face during agitating friction welding and welding the plane has an angle (A axle pivot angle), so that the stirring-head shaft shoulder can provide enough upsetting forces.Therefore, the friction stir welding lathe also should possess deflection mechanism, can adjusting range be generally-5 °～5 °.
The adjusting device of agitating friction bonding machine bed A axle pivot angle in the market can be divided into fixed and adjustable two kinds.But fixed adjusting device is to utilize the wedge with fixed angle to be placed between deflection main shaft and headstock, wedge contacts respectively cooperation with headstock with spindle drum, this method of adjustment can realize the face contact of hold down gag, stressed better, the angle adjustment good stability, but the inclination angle is certain value, and is non-adjustable.The adjustable type adjusting device is arranged symmetrically in spindle drum both sides by two groups of screws, utilizes the push-and-pull action of set screws to be screwed into by adjusting both sides set screws screw thread the beat that length realizes main shaft.This device makes welding A axle swinging adjustable continuously, weak point be the simple screw adjustment spindle drum that makes load with screw head between to contact be the line contact, the load weak effect, be applicable to weld upset force and the little agitating friction bonding machine bed of drag that advances, when the welding upsetting force is larger, the soldering angle poor stability serious also can occur during indentation even embeds spindle drum on the spindle drum surface, affects the stability of welding process.
The utility model content
The utility model provides a kind of agitating friction bonding machine bed mechanical type A axle pivot angle to regulate and fixture for the problem that exists in above-mentioned existing apparatus, and simple in structure, stressed good, rigidity is high, and the angle adjustment good stability is easy to realize, but has generalization.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of agitating friction bonding machine bed mechanical type A axle pivot angle is regulated and fixture, described device mainly by: compact heap, compress transfer block, screw, nut and form, wherein, screw is arranged in the headstock screwed hole, the compression transfer block is arranged in compact heap; Screw screws in the compact heap screwed hole and dock with the blind hole that compresses transfer block, on screw partly polished rod partly with the threaded engagement of compact heap, prevent that screw and compact heap from coming off; Control the screw-in amount of screw, the traction compact heap drives spindle drum and on the Inclination maneuver plane, beat occurs, and realizes the adjusting of agitating friction welding A axle pivot angle, and adjustment process compresses transfer block self adaptation rotation in compact heap, the face contact that confining force transmits; After adjusting to the required angle of technique, fastening nut is realized double nut locking anti-loosing effect, fixing welding A axle pivot angle.
Described compact heap is simultaneously the plane, is parallel on the plane of this face to have screwed hole, perpendicular to the side with this face, the arc hole slot is set; Described compression transfer block is simultaneously arcwall face, is embedded in the deep-slotted chip breaker of compact heap, and one side has blind hole.
The deep-slotted chip breaker of described compact heap is circular trough, and compressing the fast arcwall face of switching is the face of cylinder.
Plane of described compact heap and spindle drum contacts side surfaces.
Described compression transfer block is placed in the compact heap arc-shaped slot.
Described screw is installed in the compact heap screwed hole, and front end is placed in the blind hole of compact heap, realizes compact heap and compresses fast being connected of switching.
The polished rod part of described screw is placed in respectively and compresses transfer block blind hole and compact heap screwed hole, and the threaded portion of screw is connected with headstock, can prevent that screw from coming off from compact heap.
Described screw can rotatablely move in the screwed hole of headstock, controls the different value of the screw-in amount of two rows screw, just can realize the adjusting at the different welding procedures of main shaft inclination angle.
The tight transfer block motion of described screw belt dynamic pressure compresses can moving of transfer block in the circular trough of compact heap, the self adaptation adjustment of implement device guarantees that the stressed way of contact is the face contact.
Described nut is tightened on headstock after angle adjustment is good, keeps the double nut locking of welding process screw, fixing welding A axle swinging.
The revolute pair that the stirring friction-welding technique Inclination maneuver that the utility model provides and fixture adopt can realize the self adaptation adjustment of Inclination maneuver timer, and assurance device is always face with the way of contact of main shaft and contacts.。
Advantage of the present utility model:
1. by utilizing compact heap and compressing transfer block, coordinate with set screws, realize in the Inclination maneuver process main
Axle is always face with adjusting device and contacts, and increases force-applied area, thereby has improved rigidity and the bearing capacity of Inclination maneuver frame for movement, angle adjustment good stability.
2, utilize the revolute pair of compact heap and compression transfer block, compact conformation takes up room little, changes the stressed relatively poor line way of contact way of contact of into stressed face preferably, but self adaptation is adjusted the deflection of the angle of screw and main shaft, realizes the adjustable continuously of welding procedure inclination angle.
3, utilize the screw hole on nut and headstock to realize that double nut locking is locking, guarantee the stable of welding A axle pivot angle.
4, to be delivered to the power on screw be axial compressive force to the drag of advancing of main shaft, improves the bearing capacity of device; The polished rod place of screw coordinates with compact heap screw thread place, prevents screw and compresses fast coming off.
5, the Inclination maneuver fixture structure is simple, and part processing is simple, can realize modularization.Be arranged on respectively by screw on two parallel planes of main shaft mount pad, be convenient to install and adjust, be easy to realize.
