Abstract
The utility model discloses an aluminum alloy weld surface defect repairing device and belongs to a repairing device. The aluminum alloy weld surface defect repairing device comprises a clamping device and a friction head which are connected. The aluminum alloy weld surface defect repairing device can effectively repair aluminum alloy weld surface defects.
Description
Technical field
The utility model belongs to a kind of prosthetic device, is specifically related to a kind of welded seam of aluminium alloy blemish prosthetic device.
Background technology
Aluminum alloy materials is a kind of very common process materials, is able to extensive use in the industries such as Aeronautics and Astronautics, boats and ships, electronics.At present, the common connected mode of aluminium alloy mainly comprises melting welding and friction stir welding.Common arc-seam weld blemish comprises that mainly face crack, undercut, surperficial reinforcement are excessive etc., has affected the presentation quality of weld seam.At present, both at home and abroad melting welding blemish repair mode is: first defective is dug drain clean after, then fill up with melting welding, adopt the method grain growth to occur because weld seam experiences thermal cycle again, affect the joint quality of weld seam.
Although friction stir welding is a kind of solid phase interconnection technique of green, the common defectives of melting welding such as crackle, undercut can not appear, if but Control Welding Process was not at that time, also easily produce other various defectives, its surperficial defective mainly contains surface grooves, flies to show burr, surface peeling plays silk etc.; When blemish adopts friction stir welding again to weld, although can repair to a certain extent the blemish of weld seam, but another the impact that is subject to thermal cycle of whole weld seam causes the tensile strength of weld seam to reduce, and can stay at face of weld the keyhole of mixing needle shape size.
The utility model content
The purpose of this utility model is address the above problem and a kind of welded seam of aluminium alloy blemish prosthetic device is provided.This device can effectively be repaired the aluminum alloy surface defective.
The technical scheme that the utility model adopts is:
A kind of welded seam of aluminium alloy blemish prosthetic device comprises clamping device and friction head, and described clamping device is connected with described friction head.
Further, be fixed by trip bolt between described clamping device and described friction head.
Further, the working face of described friction head is the indent inclined-plane.
A nearlyer step ground, the angle on the indent inclined-plane of described friction head is 6 °～10 °.
Preferably, the material of described friction head is 4Cr5MoSiV1.
The utlity model has following advantage:
This apparatus structure is simple, and production cost is low, utilizes this device effectively effectively to repair the face of weld defective of aluminium alloy melting welding and friction stir welding generation, and intensity and the shaping surface that can not reduce welded seam of aluminium alloy when repairing are poor.
Description of drawings
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
The structural representation of a kind of welded seam of aluminium alloy blemish prosthetic device that Fig. 1 provides for the utility model embodiment 1;
The structural representation of friction head in a kind of welded seam of aluminium alloy blemish prosthetic device that Fig. 2 provides for the utility model embodiment 1.
The specific embodiment
See figures.1.and.2, a kind of welded seam of aluminium alloy blemish prosthetic device comprises clamping device 1 and friction head 3.Clamping device 1 is connected with friction head 3, and is fixed by trip bolt 2.Hold assembly 1 mainly plays the effect that connects friction head 3 and machine tool chief axis, and the material of hold assembly 1 is stainless steel.The working face of friction head 3 is the indent inclined-plane, and the angle on the indent inclined-plane of friction head 3 is 10 °, the working face of friction head 3 be the indent inclined-plane be for the aluminum alloy welding seam surface that makes reparation Paint Gloss.The material of friction head 3 is 4Cr5MoSiV1.Lower and total alloy content is also lower due to phosphorus content, usually has good toughness under HRC40～HRC55 work hardness, vanadium can improve corrosion resistance at high temperature, element silicon can improve at 800 ° of antioxygenic properties below C of high temperature, after this material quenches, hardness can reach HRC48～HRC51, so 4Cr5MoSiV1 is suitable as the material of friction head 3 very much.
The working method of this device is to utilize friction head 3 and be repaired face of weld spin friction and produce heat, make the metal of the part of face of weld reach the thermoplasticity state, and thermoplastic surface metal is gathered in the indent profile, in the relative process of advancing, the thermoplasticity metal is evenly distributed in its rear.The operating process of this device is: clamping device 1 is assembled on the main shaft of lathe agitating friction soldering equipment, it is 3 ° with the Inclination maneuver of main shaft, the rotary speed of main shaft is 600rpm, and regulate gradually the decrease speed of this device until concordant with face of weld, then this device is pressed to 0.1mm, the gait of march of this device is 300mm/min, thereby realizes the reparation of face of weld defective.Aluminum alloy welding seam surface before repairing, there is a large amount of filiforms in weld seam both sides, the appearance of weld extreme difference.After utilizing this device to repair, appearance of weld is good, has eliminated the filiform of former face of weld.
The present embodiment as different from Example 1, the angle on the indent inclined-plane of friction head 3 is 6 °.The operating process of this device is: clamping device 1 is assembled on the main shaft of lathe agitating friction soldering equipment, it is 5 ° with the Inclination maneuver of main shaft, the rotary speed of main shaft is 1000rpm, and regulate gradually the decrease speed of this device until concordant with face of weld, then this device is pressed to 0.15mm, the soldering set gait of march is 600mm/min.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
