[0029] A friction welding machine capable of removing burrs, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 As shown, it includes a machine tool 1, an electric guide rail 2, a spindle box 3, an electric push rod 31, a grinding knife 32, a three-jaw chuck 4, a fixing mechanism and a burr removal mechanism, the electric guide rails 2 are installed on both the front and rear sides of the top of the machine tool 1, the spindle box 3 is installed on the right side of the machine tool 1, the electric push rod 31 is installed on the top of the spindle box 3, the grinding knife 32 is connected to the telescopic rod of the electric push rod 31, a through opening is provided in the middle of the spindle box 3, the three-jaw chuck 4 is installed at the output shaft of the spindle box 3, the electric guide rail 2 is provided with a fixing mechanism for fixing the workpiece, the machine tool 1 is provided with a burr removal mechanism for removing burrs inside the workpiece, and the burr removal mechanism passes through the through opening.

[0030] like Figure 2 As shown, the fixing mechanism includes a cylinder 51, an arc-shaped clamping plate 52 and a mounting plate 53. The cylinder 51 is installed on the moving bodies of the two electric guide rails 2. The telescopic rod of the cylinder 51 is connected with the arc-shaped clamping plate 52. The workpiece is placed between the arc-shaped clamping plates 52 on both sides, and the telescopic rod of the cylinder 51 is controlled to extend to drive the two arc-shaped clamping plates 52 to clamp the workpiece, so that the workpiece can be fixed. The mounting plate 53 is connected between the left sides of the moving bodies of the two electric guide rails 2.

[0031] like Figure 2 , Figure 3 , Figure 4 and Fig. 9As shown, the burr removal mechanism includes a slide rail 60, a slider 61, a column 62, a sliding frame 63, a handle 64, a grinding rod 65 and an elastic member 66. The slide rail 60 is connected to the right side of the top of the machine tool 1, and the slide rail 60 is slidably connected to the slider 61. The slider 61 can slide left and right along the slide rail 60. The top of the slider 61 is connected to the column 62, and the sliding frame 63 is slidably connected to the column 62. The sliding frame 63 can slide up and down along the column 62. The sliding frame 63 is connected to the handle 64. The left side of the sliding frame 63 is connected to the grinding rod 65. The sliding frame 63 and the grinding rod 65 are both located in the through opening, and the grinding rod 65 passes through the through opening. The grinding rod 65 can extend into the interior of the tubular workpiece. An elastic member 66 is connected between the sliding frame 63 and the column 62, and the elastic member 66 is a return spring.

[0032] When friction welding of tubular workpieces is required, this friction welding machine can be used. During use, the workpiece to be welded is first placed between the two arc-shaped clamping plates 52, and then the telescopic rod of the cylinder 51 is controlled to extend to drive the two arc-shaped clamping plates 52 to approach each other, thereby fixing the workpiece to be welded, and then the three-jaw chuck 4 is used to fix the other workpiece, and then the spindle box 3 can be controlled to drive the three-jaw chuck 4 to rotate, and then the electric guide rail 2 drives the cylinder 51 and the arc-shaped clamping plate 52 to move to the right, so that the two sections of the workpiece contact each other, and then the rotation of the spindle box 3 can cause the friction between the workpieces to generate heat and melt, and the two workpieces are welded together. After welding is completed, the telescopic rods of the two cylinders 51 can be controlled to retract so that the arc-shaped clamping plate 52 is separated from the workpiece. At this time, the three-jaw chuck 4 continues to operate to drive the workpiece to rotate. When it is necessary to remove the burrs inside the workpiece, the handle 64 can be operated to drive the sliding frame 63 to move downward, the elastic member 66 is compressed, and then the column 62 is pushed to move to the left, thereby driving the grinding rod 65 to contact the inner wall of the welding place of the two workpieces. At the same time, the telescopic rod of the electric push rod 31 can be controlled to extend to drive the grinding knife 32 to move downward, so that the grinding knife 32 contacts the outer wall of the welding place of the two workpieces. At this time, with the rotation of the workpiece, the burrs on the inner and outer walls of the welding place can be polished and removed. In this way, the present device can be used to perform friction welding on the tubular workpiece, and after welding, the burrs on the welding place of the inner wall of the tubular workpiece can also be polished and removed to avoid the burrs affecting subsequent use.

[0033] like Figure 5As shown, a transmission mechanism is also included, which includes a connecting rod 71, a connecting plate 72 and an elastic member 73. The right sides of the two cylinders 51 are connected to connecting rods 71, and the connecting rods 71 ​​are slidably connected to the spindle box 3. The movement of the connecting rods 71 ​​is guided by the spindle box 3. The right side of the connecting rod 71 is connected to a connecting plate 72, and the connecting plate 72 is connected to the column 62 so that the cylinder 51 can drive the column 62 to move through the connecting rod 71 and the connecting plate 72 when moving. The connecting plate 72 is slidably connected to the spindle box 3, and an elastic member 73 is connected between the connecting plate 72 and the spindle box 3, and the elastic member 73 is a reset spring.

[0034] like Figure 6 and Fig. 9 As shown, it also includes a pressing mechanism, which includes an extension shaft 74, a guide block 75 and a screw 76. The front and rear sides of the right side of the spindle box 3 are connected to the extension shaft 74, and the middle positions of the front and rear sides of the sliding frame 63 are provided with fan-shaped grooves, and the guide blocks 75 are rotatably connected in the fan-shaped grooves. The fan-shaped grooves can limit the movement of the guide blocks 75. The extension shaft 74 is slidably connected to the guide blocks 75, and the guide blocks 75 are threadedly connected to the screws 76. The screws 76 can rotate to resist the sliding frame 63, thereby fixing the guide blocks 75 on the sliding frame 63.

[0035] After the welding of the workpiece is completed, the cylinder 51 is controlled to drive the arc clamping plate 52 to loosen the workpiece, and the electric guide rail 2 can be controlled to drive the cylinder 51 to move to the left. When the cylinder 51 moves to the left, it drives the connecting rod 71 to move to the left. The connecting rod 71 moves to the left and drives the connecting plate 72 to move to the left. The elastic member 73 is compressed, and the connecting plate 72 moves to the left and drives the column 62 to move to the left. When the column 62 moves to the left, it drives the sliding frame 63 to move. When the sliding frame 63 moves, it drives the guide block 75 to move. At this time, the extension shaft 74 will squeeze the guide block 75, so that the guide block 75 moves downward. , thereby driving the sliding frame 63 to move downward, so as to drive the grinding rod 65 to move downward and contact the inner wall of the welding position of the workpiece. In this way, the grinding rod 65 can be automatically driven to move to contact the welding position inside the workpiece, and the operation is more convenient. In actual operation, the screw 76 can be loosened according to the size of the inner diameter of the pipe workpiece, and then the guide block 75 can be rotated for adjustment to adjust the inclination angle of the guide block 75. As the inclination angle is adjusted, the distance that the extension shaft 74 squeezes the guide block 75 to move also changes, thereby achieving the effect of adjusting according to the size of the inner diameter of the pipe workpiece.

[0036] like Figure 7-Figure 9As shown, it also includes a blowing mechanism, which includes an air pump 81, an air injection pipe 82 and an air nozzle 83. The air pump 81 is installed on the top of the spindle box 3, and the air outlet end of the air pump 81 is connected to the air injection pipe 82. The air nozzles 83 are installed on the front and rear sides of the sliding frame 63. The air nozzles 83 are located in the through-hole of the spindle box 3 and the air injection end thereof is aligned with the left side of the machine tool 1. The end of the air injection pipe 82 is forked into two and respectively connected to the two air nozzles 83, so that when the air pump 81 is in operation, the gas can be injected into the air nozzle 83 through the air injection pipe 82, and then the gas is ejected through the air nozzle 83 to blow out impurities in the burr removal process. The air nozzle 83 is located in the through-hole of the spindle box 3.

[0037] like Figure 7 and Fig.10 As shown, a material blocking mechanism is also included, and the material blocking mechanism includes a material blocking plate 91 and an elastic member 92. The material blocking plate 91 is slidably connected to the top of the mounting plate 53. When the workpiece is placed, the workpiece can squeeze the material blocking plate 91 to move downward. Two elastic members 92 are connected between the material blocking plate 91 and the mounting plate 53, and the elastic member 92 is a tension spring.

[0038] When placing the workpiece, the workpiece can squeeze the baffle plate 91 to move downward, and the elastic member three 92 is stretched. Then, after the inner wall of the workpiece is polished, the cylinder 51 can drive the mounting plate 53 and the baffle plate 91 to move leftward when it moves to the left. After the baffle plate 91 moves to the left and is released from the squeezing of the workpiece, the baffle plate 91 is reset under the action of the elastic member three 92 to block the left side of the workpiece. At this time, the air pump 81 can be controlled to blow air toward the inner wall of the workpiece through the air injection pipe 82 and the air nozzle 83 to blow out the debris inside the workpiece, and the baffle plate 91 can block the debris to prevent it from flying around.

[0039] like Fig.11 As shown, a collecting mechanism is also included, which includes a guide hopper 111, an arc-shaped baffle 112 and a collecting frame 113. The guide hopper 111 is connected to the middle position on the right side of the top of the machine tool 1, and the guide hopper 111 is located at the lower left of the three-jaw chuck 4. The upper parts of the front and rear sides of the guide hopper 111 are connected to arc-shaped baffles 112, and the arc-shaped baffles 112 are used to block the debris sputtered during friction welding. The top of the machine tool 1 is slidably connected to the collecting frame 113, and an opening is opened in the middle of the top of the machine tool 1, and the opening is located above the collecting frame 113. The end of the guide hopper 111 is aligned with the opening, so that the debris sputtered during friction welding will fall into the collecting frame 113, and the debris at the guide hopper 111 can slide into the collecting frame 113 for collection, and the debris blown away by the air nozzle 83 will also fall into the collecting frame 113 and be collected by the collecting frame 113.
