この考案は、二つの加工片を摩擦圧接する摩擦
圧接装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a friction welding device for friction welding two work pieces.
〔従来の技術〕
従来より、クランプ機構で夫々把持した二つの
加工片の対向する接合面を所定の位置で突き合
せ、この二つの加工片を所定の推力下で相対的に

押圧して二つの加工片を接合する摩擦圧接法が広
範に使用されている。[Prior Art] Conventionally, opposing joint surfaces of two workpieces each gripped by a clamp mechanism are butted against each other at a predetermined position, and the two workpieces are rotated relative to each other under a predetermined thrust, or one of them is While rotating one workpiece, the other workpiece is pressed to generate heat by frictional heat on each contact surface, and when each contact surface reaches a sufficiently high temperature, a second workpiece is applied to the two relatively rotating workpieces. A friction welding method is widely used in which two workpieces are joined by applying a thrust force of 2 or by suddenly stopping one rotating workpiece and pressing the other workpiece.
ところで、この摩擦圧接法は、接合する二つの
加工片が異種金属の場合は高強度側の金属の接触
面について、また接合する二つの加工片が同種の
金属で異径の場合は大径側の金属の接触面につい
て、それぞれその直角度が悪いと接触面の発熱が
不均一となり、さらに前記接触面に錆、油脂等が
付着していると、圧接後も錆等が残留して不完全
な接合となる欠点がある。 By the way, this friction welding method applies to the contact surface of the metal on the high-strength side when the two workpieces to be joined are of different metals, and on the large-diameter side when the two workpieces to be joined are of the same type of metal and have different diameters. Regarding metal contact surfaces, if the perpendicularity of each contact surface is poor, heat generation on the contact surfaces will be uneven.Furthermore, if rust, oil, etc. adhere to the contact surfaces, rust, etc. will remain even after pressure welding, resulting in incomplete welding. The disadvantage is that it creates a rough bond.
そこで、従来においては、加工片の接触面を予

脱脂処理を行う方法が試みられているが、防錆お
よび脱脂処理を必要とするため、作業が面倒とな
り工程数も増加する欠点を有していた。 Therefore, in the past, a method has been attempted in which the contact surface of the work piece is cut in advance and subjected to rust prevention treatment, and then degreased immediately before pressure welding, but since rust prevention and degreasing treatment are required, This method has the disadvantage that the work becomes troublesome and the number of steps increases.
〔考案が解決しようとする課題〕
このような観点から、二つの加工片を対向して

には圧接面の傾き（チヤツクの回転軸線に対する
直角度）を許容値内に維持する必要がある。[Problem to be solved by the invention] From this point of view, a cutting device for machining the contact surface of at least one of the workpieces is provided between two chuck means that grip the two workpieces facing each other, and The above-mentioned problem can be solved by cutting the contact surface of a predetermined workpiece immediately before pressing the two workpieces together under thrust. However, when pressing two workpieces whose contact surfaces have been machined in this way, in order to obtain sufficient joint strength at the joint, the inclination of the pressing surfaces (perpendicularity to the axis of rotation of the chuck) must be kept within an allowable value. need to be maintained.
しかしながら、例えば一方のＬ／Ｄの小さい加

トツパに当接することになる。 However, for example, when a workpiece with a small L/D is gripped by the chuck automatically or manually, the workpiece may be gripped in an inclined state due to a mistake in setting the workpiece to the chuck, and there is a gap between the back surface of the workpiece and the stopper. If the work piece with a gap formed is subjected to surface processing as it is, when they are brought into pressure contact in the next step, when said one work piece is pressed by the thrust of the other work piece held by the chuck on the other side, It overcomes the gripping force of the chuck and slips, coming into contact with the stopper on the back of the workpiece.
従つて、この状態では、前記ストツパの当接面

された圧接面は傾斜状態となり、このまま二つの
加工片を圧接接合すると、その接合部の強度が不
足し、不完全な接合となる難点を有していた。 Therefore, in this state, since the contact surface of the stopper forms a plane perpendicular to the chuck axis, the machined pressure contact surface of the work piece that is in contact with the stopper is in an inclined state, and the work piece can be kept in this state for two years. When two processed pieces are welded together by pressure welding, the strength of the joint is insufficient, resulting in an incomplete joint.

装置を提供するにある。 Therefore, the purpose of the present invention is to eliminate the need for rust prevention and degreasing treatment, and after aligning the positions (postures) of the two workpieces by pressing the workpieces blankly, surface-machining the pressure contact surface of one of the workpieces, Provided is a friction welding device that can more reliably join two workpieces together by pressure-welding the pressure-welding surface of the other workpiece to the pressure-welding surface without causing any misalignment of the gripping surface of the workpiece. There is something to do.

According to the friction welding device according to the present invention, before the welding process, an empty pressing operation is performed in which the joint surface of the workpiece held by the rotary chuck is pressed by the other workpiece to contact the stopper. This blank pressing ensures that the perpendicularity of the joint surfaces is within the allowable value. Next, the drive motor is rotated at a speed suitable for cutting the contact surface of the workpiece to rotate the workpiece via the spindle, and the cutting tool attached to the end of the piston rod is rotated in a direction perpendicular to the axis of the spindle. The contact surface is machined by cutting and feeding, and after the machining is completed, the piston rod is retreated to its original position. After this surface machining, the rotational speed of the drive motor is increased to the speed for pressure welding to rotate the workpiece at high speed, and the piston rod of the hydraulic cylinder is again advanced toward the workpiece to contact the contact surface of the workpiece. Press and weld with a predetermined pressure. In this way, the joining surfaces of both workpieces are heated by frictional heat, and when the temperature reaches a high enough temperature for joining, the power to the drive motor is cut off and the rotation of the spindle is abruptly stopped by the brake device. In synchronization with the sudden stop of the spindle, the grip on the workpiece by the chuck is released and stopped by the pressing force of the opposing workpiece, and the piston rod of the hydraulic cylinder is further advanced to apply upset pressure to both workpieces. to achieve bonding.

By moving the piston rod 36 in the axial direction of the spindle 18, the workpiece B held at 8 is pressed against or separated from the workpiece A with a predetermined thrust. In this case, the spindle 18 and the piston rod 36 are arranged on the same axis, and the rotation of the piston rod 36 is prevented by a rotation stopper (not shown).

Chuck 2 of single rotation gripping device 12
Surface machining is performed on the contact surface 50 of the workpiece A held at zero (see FIG. 2).
次に、このように構成された本考案にかかる摩
擦圧接装置により、二つの加工片を圧接接合する
場合の動作について説明する。 Next, an explanation will be given of the operation when two workpieces are pressure-welded using the friction welding apparatus according to the present invention configured as described above.
先ず、チヤツク２０およびチヤツク３８で加工
片ＡおよびＢを夫々把持し、油圧シリンダ３４の
ピストン杆３６を前進させて加工片Ｂにより加工
片Ａの空押しを行つて加工片ＡおよびＢの位置整
合を行つた後ピストン杆３６を後退させる。 First, the chucks 20 and 38 grip workpieces A and B, respectively, and move the piston rod 36 of the hydraulic cylinder 34 forward to press workpiece A with workpiece B to align the positions of workpieces A and B. After performing this, the piston rod 36 is moved back.
ここで、空押しについて簡単に説明する。 Here, blank press will be briefly explained.
すなわち、二つの加工片ＡおよびＢを圧接接合
するに際し、接合部分に充分な接合強度を得るた
めには圧接面の傾き（チヤツクの回転軸線に対す
る直角度）を許容値内に維持する必要がある。 In other words, when joining two workpieces A and B by pressure welding, in order to obtain sufficient joint strength at the joint, it is necessary to maintain the inclination of the pressure contact surface (perpendicularity to the axis of rotation of the chuck) within a permissible value. .
例えば、同径同種材圧接の場合の直径に対する
接合面の傾斜は直径100mmの場合で0.8mm以内、同
径異種材圧接の場合の直径に対する接合面の高温
強度大側傾斜は直径100mmの場合0.2〜0.5mm以内、
また、円盤状のＬ／Ｄの小さい部材の直径に対す
る接合面の傾斜は直径150mmの場合0.3〜0.75mm以
内、さらに、これと接合するシヤフト状の接合面
の傾斜は直径100mmの場合0.8mm以内というように
経験的に決められている。 For example, in the case of pressure welding of similar materials of the same diameter, the inclination of the joint surface with respect to the diameter is within 0.8 mm when the diameter is 100 mm, and in the case of pressure welding of dissimilar materials of the same diameter, the slope of the high temperature strength side of the joint surface with respect to the diameter is 0.2 in the case of 100 mm in diameter. ~0.5mm or less,
In addition, the inclination of the joint surface with respect to the diameter of a disc-shaped member with a small L/D is within 0.3 to 0.75 mm when the diameter is 150 mm, and the slope of the shaft-like joint surface to be joined to this is within 0.8 mm when the diameter is 100 mm. It has been determined empirically.
しかしながら、例えば一方のＬ／Ｄの小さい

る。 However, for example, a workpiece A with a parallel plane formed with a small L/D (thin disk shape)
When the chuck 20 automatically or manually grips the workpiece A, if the workpiece A is held in an inclined state due to a mistake in setting the workpiece A to the chuck 20, etc., the joint surface of the workpiece A is machined as it is in this state,
During the next press-welding process, when the joint surface of the work piece A in the mis-set state is pressed through the work piece B held by the chuck 38 on the other side by the thrust of the piston rod 36, the work piece A is held by the chuck 20. It overcomes the force and slides, coming into contact with the stopper S on the back of the work piece.
従つて、この状態では、前記ストツパＳの当接

工片Ａの圧接面は傾斜状態となる。しかるに、こ

の接合部はその強度が不足し、不完全な接合とな
る。 Therefore, in this state, since the abutting surface of the stopper S forms a plane perpendicular to the axis of the spindle 18, the pressing surface of the workpiece A that abuts the stopper S is inclined. However, if work piece B is pressure-welded to work piece A in this state, the strength of the joined portion will be insufficient and the joint will be incomplete.
これを防止するため、接合工程の前にチヤツク
２０に把持されている加工片Ａの接合面を相手側

合面の直角度が許容値内に確保される。 In order to prevent this, before the joining process, the joining surface of the work piece A held by the chuck 20 is pressed by the other work piece B, and the work piece A is moved to the stopper S.
A blank pressing operation is performed to bring the parts into contact with each other, and this blank pressing ensures that the perpendicularity of the joint surfaces is within the allowable value.

後退させる。 Next, the motor 28 is rotated at a speed suitable for cutting the contact surface of the workpiece A to rotate the workpiece A via the spindle 18, and the cutting device 16 rotates the cutting tool 4 attached to the end of the piston rod 44.
The contact surface 50 is machined by cutting feed in a direction perpendicular to the axial direction of the spindle 18 (see Fig. 2), and after the machining is completed, the piston rod 44 is retreated to its original position.

５０に所定の圧力で押圧圧接する。 After this surface machining, the rotational speed of the motor 28 is increased to the speed for pressure welding to rotate the workpiece A at high speed, and the piston rod 36 of the hydraulic cylinder 34 is again advanced toward the workpiece A. It is pressed against the contact surface 50 of 1 with a predetermined pressure.
このようにして、両加工片ＡおよびＢの接合面

にアプセツト圧を加え接合する。 In this way, the joining surfaces of both workpieces A and B are heated by frictional heat, and when the temperature reaches a high enough temperature for joining, the power to the motor 28 is cut off and the rotation of the spindle 18 is stopped by the brake device 24. Then, in synchronization with the sudden stop of the spindle 18, the grasping state of the workpiece A by the claws 22 of the chuck 20 is released, and the workpiece A is stopped by the pressing force of the workpiece B. At this time, Hydraulic cylinder 34
The piston rod 36 of is moved forward to remove the work pieces A and B.
Apply upset pressure to join.

As mentioned above, according to the friction welding device according to the present invention, two workpieces that rotate relative to each other or one of which rotates are brought into contact under a predetermined thrust,
In the friction welding method, which uses the frictional heat generated by this rotating contact to generate heat on each contact surface of the workpieces and press-weld the two workpieces, the two workpieces are brought into contact under thrust and pressed, and the workpieces are pressed together. By cutting the contact surface of at least one of the workpieces after positional alignment and then performing friction welding, it is possible to omit the rust prevention process of the workpiece and the degreasing process immediately before welding. This has the advantage that the perpendicularity of the contact surfaces can be reliably maintained and the strength of the press-welded joint can be further ensured due to the positional alignment effect of the workpieces due to the blank pressing of the workpieces.

る。 Further, according to the friction welding device according to the present invention, there are two chucks that are aligned on the same axis and grip two workpieces facing each other, and a rotational drive that rotates at least one of the two chucks at high speed. By consisting of a device and a cutting device that cuts the joint surface of the rotary work piece, it has the versatility of being able to join combinations of work pieces of various shapes by replacing the chuck claws, and It has various advantages such as being able to improve the reliability of the joint portion.
