Description

Technical Field

[0001] This application relates to the field of friction welding technology, specifically to a disc-type friction welding system. Background Technology

[0002] Rotary friction welding is a typical friction welding process. Conventional rotary friction welding equipment mainly consists of three parts: a mechanical system, a hydraulic system, and an electrical control system. The mechanical system refers to the machine tool part, which mainly includes a rotary power unit, a transmission device, a rotary fixture, a moving fixture, a moving device, and a pressure device.

[0003] During rotary friction welding, the first workpiece is fixed on a rotary fixture, and the second workpiece is fixed on a movable fixture. A pressure device is used to bring the movable fixture closer to the rotary fixture so that the first and second workpieces are aligned and in contact, and pressure is applied between them. At this time, the bearing holding the first workpiece is also subjected to the friction welding force while rotating, which can easily lead to a decrease in bearing accuracy and errors in welding coaxiality, thus affecting the accuracy of the welded workpiece.

[0004] In the process of rotary friction welding, the two parts to be welded need to be fixed on a rotary fixture and a moving fixture respectively before friction welding is performed. The speed at which the two parts are fixed and fed directly affects the efficiency of friction welding. Summary of the Invention

[0024] Additionally, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that practice can be carried out without these specific details.

[0025] During rotary friction welding, the first workpiece is fixed on a rotary fixture, and the second workpiece is fixed on a movable fixture. A pressure device is used to bring the movable fixture closer to the rotary fixture so that the first and second workpieces are aligned and in contact, and pressure is applied between them. At this time, the bearing holding the first workpiece is also subjected to the friction welding force while rotating, which can easily lead to a decrease in bearing accuracy and errors in welding coaxiality, thus affecting the accuracy of the welded workpiece.

[0026] In the process of rotary friction welding, the two parts to be welded need to be fixed on a rotary fixture and a moving fixture respectively before friction welding is performed. The speed at which the two parts are fixed and fed directly affects the efficiency of friction welding.

[0027] Based on this, the embodiments of this specification propose a disc-type friction welding system: such as Figures 1 to 8 As shown, the system includes a disc base 1, a first feeding mechanism, a second feeding mechanism, a grinding mechanism 2, a robotic arm 3, a friction welding mechanism 4, and a unloading mechanism. The disc base 1 is rotatable, and four clamping seats 5 are evenly arranged around its surface. The disc base 1 drives the clamping seats 5 to rotate. The first feeding mechanism, the grinding mechanism 2, the friction welding mechanism 4, and the unloading mechanism are sequentially arranged around the disc base 1 and correspond to the clamping seats 5. The grinding mechanism 2 is for mechanical friction grinding or laser grinding; in this embodiment, it is for mechanical friction grinding.

[0028] The first feeding mechanism transfers the welded parts to the clamping seat 5. The grinding mechanism 2 grinds the welded parts on the clamping seat 5. The robot arm 3 is used to transfer the welded parts on the second feeding mechanism to the friction welding mechanism 4. The friction welding mechanism 4 performs friction welding on the welded parts. By rotating the clamping seat 5 driven by the disc base 1 and feeding the parts synchronously with the robot arm 3 and the second feeding mechanism, the feeding efficiency of the welded parts is improved, thereby improving the friction welding efficiency.

[0029] The first feeding mechanism includes a placement frame 6, a support frame 7, and a positioning seat 8. The placement frame 6 holds the welded parts. The support frame 7 is connected to a first transverse sliding member 9 and a second transverse sliding member 10. The first transverse sliding member 9 is connected to a first suction cup 12 via a first vertical sliding member 11. The first suction cup 12 is used to transfer the welded parts on the placement frame 6 to the positioning seat 8. The positioning seat 8 is located between the disc base 1 and the placement frame 6. The shape of the positioning seat 8 is adapted to the shape of the welded parts. The second transverse sliding member 10 is connected to a second suction cup 14 via a second vertical sliding member 13. The second suction cup 14 is used to transfer the welded parts on the positioning seat 8 to the clamping seat 5.

[0030] The first transverse component 9, the second transverse component 10, the first vertical component 11, and the second vertical component 13 in this application can be driven by a lead screw, a cable chain, or a cylinder.

[0031] The first suction cup 12 transfers the welded part to the positioning seat 8, where the positioning seat 8 positions and corrects the welded part. The second suction cup 14 then transfers the welded part to the clamping seat 5, thereby improving the transfer efficiency and accuracy and avoiding inaccurate friction welding due to incorrect angle of the welded part.

[0032] The placement rack 6 is equipped with a conveyor belt 15, which has multiple placement boxes 16. Multiple welding parts are regularly placed in the placement boxes 16. The conveyor belt 15 moves the welding parts in the placement boxes 16 to the gripping area of ​​the first suction cup 12, which facilitates the transfer of the welding parts by the first suction cup 12.

[0033] The second feeding mechanism includes a vibrating feeding plate 17, a third transverse moving part 18, a fourth transverse moving part 19, and a burr detector 20. The third transverse moving part 18 and the fourth transverse moving part 19 are both positioned between the robot arm 3 and the vibrating feeding plate 17, with the third transverse moving part 18 positioned between the fourth transverse moving part 19 and the robot arm 3. The third transverse moving part 18 is connected to a gripper 21 and a grinding component 22. The gripper 21 and the grinding component 22 move synchronously with the third transverse moving part 18. The gripper 21 is used to transfer the welded parts, and the grinding component 22 is used to grind and deburr the welded parts. The fourth transverse moving part 19 is connected to a support platform 23.

[0034] The moving positions of the third transverse moving member 18 include the clamping position and the grinding position. When the third transverse moving member 18 is in the clamping position, the jaw 21 clamps the weldment. When the third transverse moving member 18 is in the grinding position, the jaw 21 places the weldment on the bearing table 23, and the grinding member 22 grinds the weldment.

[0035] The fourth transverse moving part 19 has two moving positions: a central position and a detection position. When the third transverse moving part 18 is in the grinding position, the fourth transverse moving part 19 is in the central position. When the third transverse moving part 18 is in the clamping position, the fourth transverse moving part 19 is in the detection position. The burr detector 20 detects burrs on the welded parts.

[0036] After inspection, the robotic arm 3 picks up the welded parts from the support platform 23 and transfers them to the friction welding mechanism 4.

[0037] The third lateral movement component 18 and the fourth lateral movement component 19 are driven by a lead screw or a cable chain.

[0038] With the cooperation of the third transverse component 18, the fourth transverse component 19 and the gripper 21, the same end face of the terminal can be ground, inspected, gripped and subsequently friction welded. While grinding the terminal, another terminal can continue to be inspected, avoiding interference with inspection and grinding during the transfer of the terminal and improving the efficiency of feeding, grinding and inspection.

[0039] The second feeding mechanism also includes a scraper 24 and a receiving basket 25. The grinding component 22 is connected to a cover 26. The bottom of the cover 26 is connected to a base plate. The two side walls of the cover 26 in the direction of movement are hinged to the cover 26. The scraper 24 is stationary. When the third transverse component 18 is in the clamping position, the scraper 24 scrapes the debris on the base plate of the cover 26 to the receiving basket 25, which can clean up the debris in time and avoid the debris from interfering with the grinding process.

[0040] The second feeding mechanism also includes a fixed base 27. A vibrating feeding plate 17 is connected to a guide groove 28, which is connected to the fixed base 27. A clamping member 29 is connected to the fixed base 27. When the welded part is located on the fixed base 27, the clamping member 29 clamps and fixes the welded part. While the clamping member 29 is clamping and fixing the welded part, the third transverse moving member 18 is in a clamping position, and the grinding member 22 grinds and deburrs the welded part. The clamping member 29 fixes the welded part, improving stability during the grinding process.

[0041] The second feeding mechanism also includes a lifting pallet 30, which is positioned between the guide trough 28 and the fixed seat 27. The fixed seat 27 is connected to a positioning cylinder 31 via a connecting rod. The positioning cylinder 31 is connected to a push rod 32, which is Z-shaped. When the weldment is located on the lifting pallet 30, the lifting pallet 30 rises, and the positioning cylinder 31 pushes the weldment between the fixed seat 27 and the clamping member 29 via the push rod 32. The end of the weldment closest to the grinding member 22 is located inside the cover 26. The positioning cylinder 31 pushes and positions the weldment via the push rod 32, improving the grinding accuracy. The lifting pallet 30 prevents the push rod 32 from interfering with other weldments during the pushing process.

[0042] The unloading mechanism includes a fifth transverse moving member 33 and a receiving box 34. The fifth transverse moving member 33 is connected to a third suction cup 36 via a third vertical moving member 35. The third suction cup 36 transfers the welded part from the clamping seat 5 to the receiving box 34 to complete the receiving. The fifth transverse moving member 33 and the third vertical moving member 35 are driven by a lead screw or a cable chain.

In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
