DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] A friction welding machine with a correction function, such as Figure 1-Figure 5 As shown, it includes a base 1, a conveying frame 2, a spindle box 3, a three-jaw chuck 4, a clamping mechanism, a limiting mechanism and a correction mechanism. The conveying frame 2 is connected to the top of the base 1, the spindle box 3 is installed on the left side of the base 1, and the three-jaw chuck 4 is installed on the output end of the spindle box 3. The conveying frame 2 is provided with a clamping mechanism for clamping a workpiece 100, and the clamping mechanism is provided with a limiting mechanism for limiting the workpiece 100 and a correction mechanism for correcting the workpiece after friction welding.

[0031] like Figure 2 and Figure 3 As shown, the clamping mechanism includes an electric guide rail 51, a sliding frame 52, a mounting seat 521, a hydraulic cylinder 53 and a clamping plate 54. The electric guide rails 51 are installed on both the front and rear sides of the top of the conveying frame 2. Two sliding frames 52 are arranged and distributed on the left and right. The sliding frame 52 on the left is connected to the moving body of the electric guide rail 51, and the sliding frame 52 on the right is slidably connected to the electric guide rail 51. The front and rear sides of the top of the sliding frame 52 are connected to the mounting seats 521. The hydraulic cylinder 53 is installed on the mounting seat 521. The clamping plate 54 is connected to the telescopic rod of the hydraulic cylinder 53. The workpiece can be placed between the clamping plates 54 on the front and rear sides, and then the extension of the telescopic rod of the hydraulic cylinder 53 can drive the clamping plate 54 to clamp the workpiece 100.

[0032] like Figure 2 and Figure 3 As shown, the limiting mechanism includes a clamping block 61 and a fixing bolt 62. The clamping block 61 is slidably connected to the upper and lower sides of the clamping plate 54. The fixing bolt 62 is threadedly connected to the clamping block 61. The fixing bolt 62 can rotate to press against the clamping plate 54 through the thread, thereby fixing the clamping block 61 on the clamping plate 54.

[0033] like Figure 4 and Figure 5As shown, the correction mechanism includes a two-way cylinder 71, a connecting frame 72, a V-shaped frame 73 and a roller 74. The two mounting seats 521 on the left are both installed with a two-way cylinder 71 on the left side. The connecting frames 72 are connected between the telescopic rods at the tops and between the telescopic rods at the bottom of the two two-way cylinders 71. The middle part of the two connecting frames 72 close to each other is connected to a V-shaped frame 73. The front and rear sides of the V-shaped frame 73 are rotatably connected to the roller 74. The operation of the two-way cylinder 71 can drive the connecting frames 72 and the V-shaped frames 73 on both sides to approach each other, so that the V-shaped frame 73 contacts and squeezes the workpiece to straighten the workpiece.

[0034] When a friction welding machine is needed, the present welding machine can be used. When in use, first place the workpiece 100 between the clamping blocks 61 of the clamping plates 54 on both sides. After placement, the telescopic rods of the hydraulic cylinders 53 on the front and rear sides can be controlled to extend to drive the clamping plates 54 and the clamping blocks 61 on the front and rear sides to approach each other, clamping the workpiece 100. Then, the three-jaw chuck 4 clamps the workpiece 200. After clamping, the electric guide rail 51 can be controlled to drive the left sliding frame 52 to move to the left. The left sliding frame 52 can pass through the clamping plate when moving. 54 pulls the workpiece 100 to move together, and when the workpiece 100 moves, it can drive the right sliding frame 52 to move together through the right clamping plate 54 and the hydraulic cylinder 53. At the same time, the spindle box 3 can be controlled to drive the three-jaw chuck 4 to rotate, driving the workpiece 200 to rotate. When the workpiece 100 moves, it can contact the workpiece 200. At this time, the friction between the workpiece 100 and the workpiece 200 generates heat and melts, so the workpiece 100 and the workpiece 200 can be welded together. After welding is completed, the three-jaw chuck 4 is controlled to stop. The hydraulic cylinder 53 is then operated to drive the clamping plate 54 to reset, so that the clamping block 61 is separated from the workpiece 100. If the workpiece 100 is deformed, the telescopic rod of the bidirectional cylinder 71 can be controlled to retract and drive the two connecting frames 72 to approach each other. When the two connecting frames 72 approach each other, they can drive the two V-shaped frames 73 and the roller 74 to approach each other, so that the roller 74 abuts against the workpiece 100. Then, the spindle box 3 is controlled to drive the three-jaw chuck 4 to rotate and drive the workpiece 2 200 and the workpiece 100 to rotate. At this time, the roller 74 can The workpiece 100 can be straightened. When the straightening position needs to be adjusted, the telescopic rod of the two-way cylinder 71 can be controlled to extend first, driving the roller 74 to separate from the workpiece 100, and then the electric guide rail 51 can be controlled again to drive the sliding frame 52 on the left to move, driving the V-shaped frame 73 and the roller 74 to move to adjust the position. After the adjustment is completed, the extrusion can be performed according to the above operation. This can be repeated, and the device can be used to friction weld the workpiece. After the friction welding is completed, the workpiece can be corrected, which is more convenient to operate.

[0035] like Figure 6-Figure 8As shown, an adjustment mechanism is also included, which includes a bidirectional screw 81, a worm 82 and a worm wheel 83. The left and right sides of the clamping plate 54 are rotatably connected with the bidirectional screw 81, and the upper and lower sides of the bidirectional screw 81 are respectively threadedly matched with the clamping blocks 61 on the upper and lower sides, so that when the bidirectional screw 81 rotates, the clamping block 61 can be driven to move through the thread, and a worm wheel 83 is connected in the middle of the bidirectional screw 81. The worm 82 is rotatably connected in the middle of the clamping plate 54, and the worm 82 is meshed with the worm wheel 83, so that when the worm 82 rotates, it can drive the worm wheel 83 to rotate.

[0036] When the position of the clamping block 61 needs to be adjusted to accommodate workpieces of different diameters - 100, the fixing bolt 62 can be loosened first, and then the worm 82 is rotated to drive the bidirectional screw 81 to rotate through the worm gear 83. When the bidirectional screw 81 rotates, it can drive the clamping block 61 to move up and down for adjustment through the thread, which makes the adjustment operation more convenient and efficient. At the same time, the rotation of the bidirectional screw 81 for adjustment can ensure the consistency of the upper and lower clamping blocks 61 when moving. After the adjustment is completed, the fixing bolt 62 can be tightened.

[0037] like Fig. 9 and Fig.10 As shown, a connecting mechanism is also included, which includes a driving motor 91, a mounting plate 92, a chain transmission group 93, an internal threaded sleeve 94 and a threaded rod 95. The right rear portion of the sliding frame 52 on the right is connected to the mounting plate 92, and the driving motor 91 is installed on the mounting plate 92. The front and rear sides of the sliding frame 52 on the right are rotatably connected to the threaded rod 95, and a chain transmission group 93 is arranged between the right sides of the two threaded rods 95. The driving motor 91 is connected to the threaded rod 95 on the rear side so that the driving motor 91 can drive the threaded rod 95 on the rear side to rotate, and the transmission of the chain transmission group 93 can drive the two threaded rods 95 to rotate together. The front and rear sides of the sliding frame 52 on the left are connected to the internal threaded sleeve 94, and the internal threaded sleeve 94 is threadedly matched with the threaded rod 95 so that the threaded rod 95 can enter the internal threaded sleeve 94 through the thread edge when rotating.

[0038] The internal threaded sleeve 94 and the threaded rod 95 can connect the two sliding frames 52 together so that the two sliding frames 52 can move synchronously. When the spacing between the two sliding frames 52 needs to be adjusted, the drive motor 91 can be controlled to drive the two threaded rods 95 to rotate through the chain transmission group 93. When rotating, the threaded rod 95 can drive the two sliding frames 52 to move closer to or away from each other through the threads between it and the internal threaded sleeve 94, so as to adjust the distance between the two sliding frames 52, which is convenient for fixing workpieces of different lengths-100.

[0039] like Fig.11 and Fig.12As shown, a supporting mechanism is also included, which includes a roller 101, a sliding shaft 102 and an elastic member 103. The sliding shaft 102 is slidably connected to the front and rear sides of the clamping block 61. Two elastic members 103 are connected between the sliding shaft 102 and the clamping block 61. The elastic member 103 is a connecting spring. The sliding shaft 102 is rotatably connected to the roller 101, and the roller 101 passes through the clamping block 61.

[0040] When the hydraulic cylinder 53 drives the clamping block 61 to clamp the workpiece 100, the roller 101 is squeezed by the workpiece 100 and retracts into the clamping block 61, and the elastic member 103 is in a compressed state. During the correction process, the clamping block 61 is separated from the workpiece 100. At this time, the sliding shaft 102 and the roller 101 are pushed out of the clamping block 61 under the action of the elastic member 103, and the roller 101 can contact the workpiece 100. When the workpiece 100 rotates, the roller 101 can support the workpiece 100 and assist the rotation of the workpiece 100.

[0041] like Fig.13 As shown, a cooling mechanism is also included, which includes a liquid spray pipe 111, a water tank 112 and a connecting pipe 113. The water tank 112 is installed on the spindle box 3, and the liquid spray pipe 111 is slidably connected to the top of the spindle box 3. A water pump is arranged in the water tank 112, and a connecting pipe 113 is connected between the water pump in the water tank 112 and the liquid spray pipe 111.

[0042] After the friction welding is completed, the water pump in the water tank 112 can be controlled to operate to spray the coolant on the welding position through the connecting pipe 113 and the spray pipe 111 to cool the welding position.

[0043] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
