Description

Technical Field

[0001] The invention belongs to the technical field of metal processing equipment, and in particular relates to a five-axis additive and subtractive material processing equipment. Background Art

[0002] Common manufacturing methods include subtractive manufacturing and additive manufacturing. Subtractive manufacturing is the process of creating an object of the desired shape by removing the original material from the whole. In the subtractive process, the material is removed by cutting, milling, turning, drilling, etc. to form the final product. Additive manufacturing is the process of creating a three-dimensional object by depositing materials layer by layer. In the additive manufacturing process, the object is built by adding materials layer by layer.

[0003] When processing extra-long pipes, you can use an alternating method of additive and subtractive processing to first process a shorter pipe, then perform subtractive processing on the pipe, and then perform additive processing on the shorter pipe after subtractive processing is completed.

[0017] like Figure 1 , Figure 3 As shown, a horizontally arranged rotating shaft 31 is rotatably mounted on the top surface of the additive machine 1, and the length direction of the rotating shaft 31 is arranged along the width direction of the additive machine 1. A first motor 32 is fixed on the additive machine 1, and the output end of the first motor 32 is fixedly connected to the end of the rotating shaft 31. A rotating table 3 is sleeved and fixed on the outer circumference of the rotating shaft 31, and a fixed table 33 is fixedly mounted on the top surface of the rotating table 3, and a processing table 34 is rotatably mounted on the top surface of the fixed table 33.

[0018] First, the laser 17 on the additive frame 15 is used to perform additive processing on the pipe fitting, and a shorter length of pipe fitting is processed on the top surface of the processing table 34. Then, the rotating table 3 is rotated to make the pipe fitting rotate to a horizontal state, and the grinding head 25 on the grinding table 24 and the milling cutter 27 on the mounting frame 26 are used to perform subtractive processing on the pipe fitting. Then, the pipe fitting is rotated to a vertical state, and the additive processing is continued. The steps of additive and subtractive processing are repeated to realize the processing of longer pipe fittings.

[0019] like Figure 4 , Figure 5 As shown, a rotating groove 41 is provided on the top surface of the processing table 34, and a rotating plate 4 is rotatably installed in the rotating groove 41. Two symmetrically arranged ventilation grooves 42 are provided on the top surface of the rotating plate 4. A blocking groove 43 is provided on the inner bottom surface of the rotating groove 41, and a blocking block 44 is installed on the processing table 34 through the blocking groove 43 to slide vertically, and the blocking block 44 can be inserted into the ventilation groove 42. A synchronous rod 46 is fixed on the bottom surface of the blocking block 44, and a blocking spring 47 is sleeved on the outer periphery of the synchronous rod 46. The end of the blocking spring 47 close to the rotating plate 4 is fixedly connected to the bottom surface of the blocking block 44, and the end of the blocking spring 47 away from the blocking block 44 is fixedly connected to the inner bottom surface of the blocking groove 43. A blowing pipe 45 is installed on the inner bottom surface of the rotating groove 41, and the blowing pipe 45 can be connected to the ventilation groove 42. The other end of the blowing pipe 45 is connected to the external high-pressure gas source, and a rotating component 5 for controlling the rotation of the rotating plate 4 is provided in the processing table 34.

[0020] After completing the subtractive processing, the sealing block 44 is separated from the ventilation groove 42, and the rotating assembly 5 is used to drive the rotating plate 4 to rotate, so that the blowing pipe 45 is connected to the ventilation groove 42, and the external high-pressure air source supplies air to the blowing pipe 45, and the gas is blown to the inner wall of the pipe through the ventilation groove 42, thereby blowing the residue on the inner wall of the pipe out of the pipe body, reducing the influence of the residue on the subsequent subtractive processing of the pipe.

[0021] like Figure 4 , Figure 5 and Figure 6As shown, the rotating assembly 5 includes a rotating rod 51 fixed to the bottom surface of the rotating plate 4, and the rotating rod 51 is coaxially arranged with the rotating plate 4. A synchronous plate 52 is fixed to the bottom end of the synchronous rod 46, and a cavity 53 is arranged in the processing table 34, and the synchronous plate 52 is slidably matched with the processing table 34 in the vertical direction through the cavity 53. A synchronous through groove 54 for passing the rotating rod 51 is provided on the top surface of the synchronous plate 52, and a clearance groove 55 is provided on the outer peripheral surface of the rotating rod 51. A clearance block 56 is fixed on the inner peripheral surface of the synchronous through groove 54, and the clearance block 56 is slidably matched with the rotating rod 51 through the clearance groove 55. The clearance groove 55 includes a vertically arranged synchronous groove 1 551 and a spirally arranged synchronous groove 2 552, and the bottom of the synchronous groove 1 551 is connected with the top of the synchronous groove 2 552. A first electromagnetic block 57 is embedded and fixed on the inner wall of the cavity 53 close to the rotating plate 4, and a first iron block 58 is embedded and fixed on the side of the synchronous plate 52 close to the first electromagnetic block 57. When the first electromagnetic block 57 is energized, it repels the first iron block 58.

[0022] When the synchronous plate 52 moves downward, it drives the synchronous rod 46 to move downward, thereby making the blocking block 44 disengage from the ventilation slot 42, and the clearance block 56 moves in the synchronous slot 1 551. The synchronous plate 52 continues to move downward, and the clearance block 56 enters the synchronous slot 2 552, thereby driving the rotating rod 51 to rotate. The rotating rod 51 drives the rotating plate 4 to rotate 90°, so that the ventilation slot 42 is connected to the air blowing pipe 45, so that the air blowing pipe 45 can blow air into the pipe body. When the first electromagnetic block 57 is not energized, the blocking block 44 is inserted into the ventilation slot 42 under the elastic force of the blocking spring 47. When the first electromagnetic block 57 is energized, the first iron block 58 moves in a direction away from the processing table 34 under the repulsive force of the first electromagnetic block 57, thereby realizing the movement of the blocking block 44 and the rotation of the rotating plate 4.

[0023] like Figure 2 , Figure 7 and Figure 8 As shown, a receiving box 6 with an opening upward is fixed on the movable frame 23, and the receiving box 6 is located below the pipe fitting. A blocking box 61 is installed above the receiving box 6 along the vertical sliding direction, and the bottom surface and the side surface close to the pipe fitting of the blocking box 61 are both opened. Two vertically arranged guide rods 62 are fixed on the top surface of the receiving box 6, and a connecting plate 63 is fixed on the top of the two guide rods 62. Guide blocks 64 are fixed on both sides of the blocking box 61, and the guide blocks 64 are sleeved on the outer periphery of the guide rods 62. A second electromagnetic block 65 is embedded and fixed on the bottom surface of the connecting plate 63, and a second iron block 66 is embedded and fixed on the top surface of the blocking box 61. The second electromagnetic block 65 can attract the second iron block 66 after being energized, and a switch 67 for controlling the opening and closing of the second electromagnetic block 65 is provided on the subtractive machine 2.

[0024] When the pipe fitting is placed horizontally, the movable frame 23 drives the grinding table 24 and the material receiving box 6 to move towards the direction close to the pipe fitting, so that the material receiving box 6 is located below the end of the pipe fitting. When the grinding head 25 performs subtractive processing on the pipe fitting, the switch 67 is started, the second electromagnetic block 65 attracts the second iron block 66, and the blocking box 61 is located above the pipe fitting. After the grinding head 25 completes the processing of the pipe fitting, the switch 67 is closed, and the blocking box 61 moves downward under the action of its own gravity. The debris in the pipe fitting is blown to the inner wall of the blocking box 61 and then falls into the material receiving box 6, which is convenient for collecting the debris.

[0025] like Figure 4 , Figure 8 and Fig. 9 As shown, the inner bottom surface of the blocking box 61 is provided with a control groove 71, and the blocking box 61 is provided with a control block 7 that slides vertically through the control groove 71. A reset block 72 is fixed on the side of the control block 7, and a reset groove 73 is provided on the inner wall of the control groove 71. The reset block 72 slides vertically with the blocking box 61 through the reset groove 73. A reset spring 74 is fixed on the bottom surface of the reset block 72, and the bottom end of the reset spring 74 is fixedly connected to the inner wall of the reset groove 73. An abutment block 68 is fixed on the bottom surface of the guide block 64, and the bottom surface of the abutment block 68 can abut against the top surface of the control block 7. A moving piece 75 is fixed on the bottom surface of the control block 7, and a fixed piece 76 for electrical contact with the moving piece 75 is fixed on the inner bottom surface of the control groove 71. The moving piece 75 is electrically connected to the first electromagnetic block 57, and the fixed piece 76 is electrically connected to the power supply.

[0026] The blocking box 61 drives the guide block 64 to move downward, and the guide block 64 drives the abutment block 68 to move downward. The abutment block 68 abuts against the control block 7 and pushes the control block 7 to move downward. The return spring 74 is in a compressed state, the moving plate 75 is in electrical contact with the fixed plate 76, and the first electromagnetic block 57 is energized to work, thereby connecting the air pipe 45 with the ventilation slot 42.

The two clamping plates 8 are respectively a fixed plate 83 installed on the subtractive machine 2 and a movable plate 87 installed on the material receiving box 6. An adjustment groove 85 is provided on the top surface of the slide rail 21, and an adjustment block 84 is fixed on the bottom surface of the fixed plate 83. The adjustment block 84 slides and cooperates with the slide rail 21 along the length direction of the slide rail 21 through the adjustment groove 85. An adjustment screw 86 is rotatably installed in the adjustment groove 85, and the adjustment screw 86 passes through the adjustment block 84. The adjustment screw 86 and the adjustment block 84 are threadedly driven. An adjustment screw 2 88 is rotatably installed on the side of the material receiving box 6 close to the additive machine 1, and a connecting rod 89 passing through the movable plate 87 is fixed on the side of the material receiving box 6. The second adjusting screw 88 passes through the movable plate 87, and the second adjusting screw 88 is threadedly matched with the movable plate 87. The position of the fixed plate 83 can be adjusted by rotating the first adjusting screw 86, and the position of the movable plate 87 can be adjusted by rotating the second adjusting screw 88, so that the milling cutter 27 can fully process the outer wall of the pipe according to the design requirements.

[0028] After the pipe is rotated to a horizontal position, the clamping block 81 on the fixed plate 83 clamps and fixes the end of the pipe close to the rotating table 3, and the clamping block 81 on the movable plate 87 clamps and fixes the end of the pipe away from the rotating table 3, so that the milling cutter 27 and the grinding head 25 can perform subtractive processing on the pipe.

[0029] like Figure 7 , Fig.10 and Fig.11 As shown, a driving rod 9 is rotatably mounted in the fixed plate 83, a third motor 91 is fixed on the side of the fixed plate 83, the output end of the third motor 91 is fixedly connected to the end of the driving rod 9, and two gears 92 are sleeved and fixed on the outer circumference of the driving rod 9. Two fixed vertical plates 93 are fixed on the top surface of the fixed plate 83, and a threaded rod 94 and a limit rod 95 are penetrated on the side of the fixed vertical plate 93, and the threaded rod 94 is threadedly matched with the fixed vertical plate 93. The end of the threaded rod 94 is rotatably connected to the clamping block 81, the end of the limit rod 95 is fixedly connected to the clamping block 81, and the outer circumference of the threaded rod 94 is sleeved with a gear 96 that meshes with the gear 92. A linkage groove 97 is opened on the outer circumference of the threaded rod 94, and a linkage block 98 is fixed on the inner circumference of the gear 96, and the linkage block 98 slides and matches with the threaded rod 94 along the length direction of the threaded rod 94 through the linkage groove 97. Two movable vertical plates 871 are fixed on the top surface of the movable plate 87, and two limit rods 872 are passed through the side surfaces of the movable vertical plates 871. The ends of the limit rods 872 are fixedly connected to the clamping block 81, and a telescopic rod 99 is fixed between one of the limit rods 872 and the limit rod 95 on the same side.

[0030] The third motor 91 is started, and the third motor 91 drives the driving rod 9 to rotate. The driving rod 9 drives the gear 2 96 to rotate through the gear 1 92. The gear 2 96 drives the threaded rod 94 to rotate through the linkage block 98 and the linkage groove 97, thereby driving the clamping block 81 to move toward the direction close to the pipe fitting. The clamping block 81 on the fixed plate 83 drives the clamping block 81 on the movable plate 87 to move synchronously through the telescopic rod 99, thereby clamping and fixing the pipe fitting.

[0031] It should be noted that when using the five-axis additive and subtractive processing equipment, the laser 17 on the additive frame 15 is first used to perform additive processing on the pipe fitting, and a shorter length of pipe fitting is processed on the top surface of the processing table 34, and then the rotating table 3 is rotated to make the pipe fitting rotate to a horizontal state, and the grinding head 25 on the grinding table 24 and the milling cutter 27 on the mounting frame 26 are used to perform subtractive processing on the pipe fitting. After completing the subtractive processing, the blocking block 44 is separated from the ventilation groove 42, and then the rotating assembly 5 is used to drive the rotating plate 4 to rotate, so that the blowing pipe 45 is connected to the ventilation groove 42, and the external high-pressure air source supplies air to the blowing pipe 45, and the gas is blown to the inner wall of the pipe fitting through the ventilation groove 42, thereby blowing the residue on the inner wall of the pipe fitting out of the pipe body, reducing the influence of the residue on the subsequent additive and subtractive processing of the pipe fitting.

[0032] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
