Description

Technical Field

[0001] The invention relates to the technical field of riser cutting, in particular to a riser cutting device for a metal casting finished product. Background Art

[0002] The oil pan is a component of the crankcase. Its function is to close the crankcase as the outer shell of the oil tank, prevent impurities from entering, and collect and store the lubricating oil flowing back from the friction surfaces of the diesel engine. The oil pan is generally made by pouring molten metal into a mold with the required shape, cooling and solidifying it, and casting risers (such as Fig.13 As shown in the figure), the pouring head is an inevitable part of the metal in the casting process. After the metal casting process is completed, the pouring head needs to be cut and removed.

[0003] After the metal oil pan is cast, a band saw is generally used to cut and remove the pouring riser. During cutting, the oil pan is clamped by a mechanical arm close to the saw blade of the band saw, and the pouring riser is cut off by the saw blade. However, the above cutting method still has the following shortcomings: 1. When the mechanical arm is moving while clamping the oil pan, the oil pan is in a suspended state. The saw blade will generate a relative force when cutting the pouring riser, which may easily cause the oil pan to shake and deviate, affecting the accuracy of the pouring riser cutting and removal; 2. As the saw blade cuts the pouring riser, the portion of the pouring riser connected to the oil pan will become less and less. When the strength of the connection between the pouring riser and the oil pan cannot support the weight of the pouring riser, the pouring riser will deviate downward under the action of its own weight, resulting in tensile deformation of the connection portion, affecting the accuracy of the saw blade cutting the pouring riser.

[0035] See also Figure 2 , Figure 3 and Figure 4 The clamping mechanism 3 includes a mounting plate 31 fixedly mounted on the robotic arm 2, an outer clamping claw 32 and an inner clamping claw 33 are slidably mounted on the bottom of the mounting plate 31, the outer clamping claw 32 and the inner clamping claw 33 are symmetrically distributed front to back, an inner support assembly 34 for driving the inner clamping claw 33 to perform internal clamping is mounted below the mounting plate 31, a clamping assembly 35 for driving the outer clamping claw 32 to perform external clamping is mounted on the top of the mounting plate 31, an L-shaped inner support plate 36 is slidably mounted on the bottom of the mounting plate 31, two plug-in blocks 37 symmetrically distributed left and right are fixedly connected to the bottom of the outer clamping claw 32, and grooves 371 are provided on opposite sides of the two plug-in blocks 37.

[0036] See also Figure 2-Figure 9 The supporting mechanism 5 includes a supporting seat 51 installed on the guiding mechanism 4, a groove matching the bottom of the oil pan 10 is provided on the top of the supporting seat 51, and plug-in grooves 52 symmetrically distributed on the front and rear sides of the top of the supporting seat 51 are provided, and first wedge blocks 53 are slidably installed on the opposite sides of the left and right plug-in grooves 52, and a downwardly inclined inclined surface is provided on one end of the first wedge block 53 extending to the corresponding plug-in groove 52, and a first compression spring 54 is fixedly connected between the side of the first wedge block 53 away from the plug-in groove 52 and the inner wall of the supporting seat 51, and an unlocking component 55 is also installed inside the supporting seat 51.

[0037] When the clamping mechanism 3 and the supporting mechanism 5 are to be locked together, the robot arm 2 drives the clamping mechanism 3 to move downward, so that the clamping mechanism 3 places the clamped oil pan 10 into the groove on the supporting mechanism 5. At this time, the plug-in block 37 is inserted into the inside of the plug-in groove 52. The plug-in block 37 first pushes the inclined surface of the first wedge block 53 to retract the first wedge block 53 into the inside of the supporting seat 51. When the plug-in block 37 completely enters the plug-in groove 52, the first wedge block 53 is aligned with the groove 371. At this time, the rebound force of the first compression spring 54 is used to push the first wedge block 53 into the inside of the groove 371, thereby locking the outer clamping claw 32 and the supporting seat 51 together, so that the clamping mechanism 3 can move forward and backward together with the supporting mechanism 5, and the movement of the clamping mechanism 3 is limited and guided, so that the subsequent oil pan 10, the clamping mechanism 3 and the supporting mechanism 5 can move stably and linearly as a whole.

[0038] See also Figure 2-Figure 5 The inner clamping claws 33 are located between the front and rear outer clamping claws 32, and the inner support assembly 34 is located between the front and rear inner clamping claws 33. The inner support assembly 34 includes a fixed plate 341 to which the opposite sides of the front and rear inner clamping claws 33 are fixedly connected. The right half of the fixed plate 341 is provided with a first slide groove 343, and a first slider 344 is installed inside the first slide groove 343 for sliding left and right. A scissor frame 342 is arranged between the front and rear fixed plates 341, and the two end portions on the left side of the scissor frame 342 are rotatably connected to the left ends of the corresponding fixed plates 341, and the two end portions on the right side of the scissor frame 342 are rotatably connected to the corresponding first slider 344, and the scissor frame 342 is also provided with an expansion component for pushing it to expand outward.

[0039] See also Figure 2-Figure 5 The expansion support component includes a push plate 345 fixedly connected to the right end of the L-shaped inner support plate 36 and located above the scissor frame 342. The bottoms of the front and rear ends of the push plate 345 are rotatably connected to the second slider 346. The right ends of the two scissor arms of the scissor frame 342 are each provided with a second slide groove 347, and the second slider 346 is slidably installed in the corresponding second slide groove 347.

[0040] When the oil pan 10 is to be clamped, the inner clamping claw 33 is placed into the inner side of the oil pan 10, and the L-shaped inner support plate 36 is pushed to move to the left by the clamping assembly 35, and then the L-shaped inner support plate 36 drives the push plate 345 and the second slider 346 to move to the left. The second slider 346 slides along the second slide groove 347 during the movement to the left, and the second slider 346 is used to push the two scissor arms of the scissor frame 342 to open outward. During the process of the scissor frame 342 opening outward, the first slider 344 moves to the left along the first slide groove 343, and the first slider 344 is used to push the fixing plate 341 and the inner clamping claw 33 to expand outward, so that the inner clamping claw 33 clamps and fixes the oil pan 10 internally.

[0041] See also Figure 2-Figure 6 The clamping assembly 35 includes a slot frame 351 fixedly mounted on the top of the mounting plate 31, a bidirectional lead screw 352 is rotatably mounted inside the slot frame 351, and the front and rear ends of the bidirectional lead screw 352 are threadedly connected to a third slider 353, a driving motor 354 for driving the bidirectional lead screw 352 to rotate is fixedly mounted on the front side of the slot frame 351, a connecting plate 1 355 is fixedly connected to the left side of the third slider 353, the bottom of the connecting plate 1 355 passes through the bottom of the mounting plate 31 and is fixedly connected to the corresponding outer clamping claw 32, the connecting plate 1 355 is slidably mounted on the mounting plate 31 front and back, the top of the L-shaped inner support plate 36 is fixedly connected to the connecting plate 2 356, the connecting plate 2 356 is slidably mounted on the mounting plate 31 left and right, the top of the connecting plate 2 356 passes through the top of the mounting plate 31 and is rotatably connected to two linkage rods 357 symmetrically distributed front and back, and the end of the linkage rod 357 away from the connecting plate 2 356 is rotatably connected to the corresponding connecting plate 1 355.

[0042] When the oil pan 10 is to be clamped, the robot arm 2 lowers the outer clamping claw 32 to the outside of the oil pan 10, and drives the bidirectional lead screw 352 to rotate through the driving motor 354, so that the two third sliders 353 move toward each other, and then the third slider 353 drives the front and rear outer clamping claws 32 to move toward each other through the connecting plate 1 355, so that the outer clamping claws 32 clamp and fix the oil pan 10 externally. When the front and rear connecting plates 1 355 approach each other, the connecting plate 1 355 pushes the connecting plate 2 356 to move to the left through the linkage rod 357, and then the connecting plate 2 356 pushes the L-shaped inner support plate 36 to move to the left, so that the L-shaped inner support plate 36 can internally support the part of the oil pan 10 close to the pouring riser 101, thereby improving the stability of the cutting and separation part of the oil pan 10 and the pouring riser 101, and at the same time realizing effective internal and external clamping and fixation of the oil pan 10.

[0043] See also Figure 1-Figure 10 The unlocking assembly 55 includes a movable plate 551 that is slidably installed inside the supporting seat 51 up and down, a return spring 2 552 is fixedly connected between the bottom of the movable plate 551 and the inner wall of the supporting seat 51, the top of the movable plate 551 is connected to the corresponding first wedge block 53 through a fixedly connected pull rope 553, a second wedge block 554 is slidably installed on the rear side of the supporting seat 51, the inclined surface at the front end of the second wedge block 554 slides with the movable plate 551, a baffle 555 is fixedly connected to the top of the second wedge block 554, a return spring 3 556 is fixedly connected between the front side of the baffle 555 and the inner wall of the supporting seat 51, and a baffle 557 located directly behind the second wedge block 554 is fixedly connected to the top of the cutting table 1.

[0044] When the robot arm 2 pushes the support seat 1 51 to move backward to the stopper 557, the pouring head 101 and the oil pan 10 are completely cut and separated, and the second wedge block 554 is blocked by the stopper 557 and pushed into the inside of the support seat 1 51. At this time, the second wedge block 554 will push the movable plate 551 to move downward, and then the movable plate 551 pulls the first wedge block 53 back into the inside of the support seat 1 51 through the pull rope 553, and the first wedge block 53 is unlocked from the plug-in block 37. After that, the robot arm 2 only needs to drive the mounting plate 31 By moving upward, the plug-in block 37 can be pulled out from the plug-in slot 52, so that the outer clamping claw 32 is separated from the supporting seat 1 51; when the stop block 557 no longer pushes the second wedge block 554, the return spring 3 556 is used to push the baffle plate 555 and the second wedge block 554 to move backward and reset, and then the return spring 2 552 is used to push the movable plate 551 to move upward and reset. At this time, the pull rope 553 no longer pulls the first wedge block 53, and the resilience of the first compression spring 54 is used to push the first wedge block 53 to move back into the plug-in slot 52.

[0045] See also Figure 1 , Figure 7 , Fig. 9 and Fig.10 The guide mechanism 14 includes two guide grooves 41 opened on the top of the cutting table 1 and parallel to each other. A movable block 42 is slidably installed inside the guide groove 41. The front ends of the two movable blocks 42 are connected by a fixedly connected U-shaped frame. A return spring 143 is fixedly connected between the rear end of the movable block 42 and the inner wall of the guide groove 41. A supporting seat 151 is fixedly installed on the top of the right movable block 42.

[0046] After the clamping mechanism 3 and the supporting mechanism 15 are locked together, the robot arm 2 pushes the clamping mechanism 3 and the supporting mechanism 15 to move backward together, ensuring that the pouring head 101 and the oil pan 10 always remain in a relatively stable state during cutting, and the supporting seat 151 drives the movable block 42 on the right to slide backward along the guide groove 41, and the movable block 42 on the right drives the movable block 42 on the left and the supporting mechanism 26 to move backward together through the U-shaped frame. At this time, the reset spring 143 will be compressed, and the guide groove 41 guides the movable block 42, so that the movable block 42 moves backward stably to avoid the oil pan 10 from deflecting during the moving cutting process; when the clamping mechanism 3 and the supporting mechanism 15 are unlocked and removed, the movable block 42 is pushed forward by the rebound force of the reset spring 143, and then the movable block 42 drives the supporting mechanism 15 and the supporting mechanism 26 to move forward and reset.

[0047] See also Figure 1 , Figure 7 , Fig. 9 , Fig.10 and Fig.12The supporting mechanism 6 includes a supporting seat 61 fixedly mounted on the top of the left movable block 42. A supporting groove 62 matching the pouring riser 101 is provided on the top of the right side of the supporting seat 61. A third wedge block 63 is slidably mounted on the left side of the supporting groove 62. The right end of the third wedge block 63 is a downwardly inclined inclined surface. A push-pull plate 64 is fixedly connected to the left end of the third wedge block 63. A second compression spring 65 is fixedly connected between the left side of the push-pull plate 64 and the inner wall of the supporting seat 61. The top of the push-pull plate 64 moves through the top of the supporting seat 61. The supporting seat 61 and the supporting seat 1 51 are respectively located on the left and right sides of the saw blade of the band saw machine 11.

[0048] When the oil pan 10 is lowered into the groove at the top of the supporting seat 51, the pouring riser 101 is lowered into the supporting groove 62 at the same time. During the lowering process, the pouring riser 101 will first push the third wedge block 63 to move leftward, so that the third wedge block 63 retracts into the interior of the supporting seat 2 61. When the pouring riser 101 is completely placed in the supporting groove 62, the rebound force of the second compression spring 65 is used to push the push-pull plate 64 and the third wedge block 63 to move rightward, so that the third wedge block 63 blocks the top of the pouring riser 101, thereby supporting and fixing the pouring riser 101 and improving the stability of the pouring riser 101 when cutting; after the pouring riser 101 is cut and separated, the push-pull plate 64 is pushed to move leftward, and then the push-pull plate 64 drives the third wedge block 63 to move leftward to release the fixation of the cut and separated pouring riser 101, and then the pouring riser 101 can be taken out of the supporting groove 62.

[0049] See also Figure 1-Figure 4 , Figure 7 , Fig. 9 and Fig.11 The guide mechanism 2 7 includes a vertical plate 71 fixedly installed on the right side of the cutting table 1, a T-shaped slot 72 is opened on the left side of the vertical plate 71, a bell mouth 73 located above the T-shaped slot 72 is fixedly connected to the top of the vertical plate 71, the small mouth end of the bell mouth 73 is downward and connected to the top of the T-shaped slot 72, an outlet 74 is opened on the rear side of the bottom end of the T-shaped slot 72, and a T-shaped block 75 slidingly matched with the T-shaped slot 72 is fixedly connected to the right side of the top of the mounting plate 31.

[0050] When the robot arm 2 drives the clamping mechanism 3 to move above the supporting mechanism 5, the T-shaped block 75 is aligned with the bell mouth 73 up and down, and then the robot arm 2 drives the clamping mechanism 3 to move downward. At this time, the T-shaped block 75 slides into the T-shaped slot 72 under the guidance of the bell mouth 73. The T-shaped slot 72 is used to limit and guide the T-shaped block 75, which can avoid the front, back, left and right misalignment of the mounting plate 31 during the downward movement, and improve the accuracy of the docking between the plug-in block 37 and the plug-in slot 52. When the clamping mechanism 3 drives the supporting mechanism 5 to move backward, the T-shaped block 75 moves backward from the outlet 74.

[0051] See also Figure 1, Figure 7 and Figure 8 The top of the cutting table 1 and the bottom of the horizontal section of the band saw 11 are both rotatably mounted with guide wheels 12 that are symmetrically distributed about the saw blade of the band saw 11, and the guide wheels 12 abut against the surface of the saw blade.

[0052] When the saw blade is working, the guide wheel 12 clamps the upper and lower sides of the saw blade cutting part. The guide wheel 12 will continuously rotate during the movement of the saw blade. The guide wheel 12 is used to clamp the saw blade to improve the stability of the saw blade during cutting and improve the flatness of the cut surface during cutting.

[0053] See also Figure 1 and Fig.13 The cutting device also includes a conveyor 8 and a conveyor 9 symmetrically distributed on the left and right sides of the robot arm 2. A centering positioning mechanism for centering the oil pan 10 is installed on the top of the right end of the conveyor 8. The centering positioning mechanism includes a fence in a U-shaped structure installed on the top of the right end of the conveyor 8. Electric push rods symmetrically distributed front and back are installed on the front and back sides of the fence.

[0054] The cast oil pan 10 is transported and loaded through a conveyor 8. When the oil pan 10 moves to the right end of the conveyor 8, it stops moving, and a fence is used to block the right side of the oil pan 10. Then, the electric push rods in the front and rear directions simultaneously push the oil pan 10 inward to center it, so that the subsequent robot arm 2 drives the clamping mechanism 3 to clamp the oil pan 10. After the pouring spout 101 on the oil pan 10 is cut off, the robot arm 2 clamps the oil pan 10 through the clamping mechanism 3 and moves it to the conveyor 2 9, so that the conveyor 2 9 transports and unloads the oil pan 10.

[0055] See also Figure 1-Figure 13 During specific use, step 1, in the initial state, the robot arm 2 drives the mounting plate 31 to move to the top of the right end of the conveyor 8, and the oil pan 10 is transported and loaded through the conveyor 8. When the oil pan 10 moves to the right end of the conveyor 8, the electric push rods on the front and rear sides are extended to center the oil pan 10.

[0056] Step 2: The mechanical arm 2 drives the mounting plate 31 to move downward, so that the outer clamping claw 32 moves downward to the outside of the oil pan 10, and at the same time, the inner clamping claw 33 and the L-shaped inner support plate 36 move downward to the inside of the oil pan 10, and then the driving motor 354 drives the bidirectional lead screw 352 to rotate, so that the two third sliders 353 move toward each other, and then the third slider 353 drives the two outer clamping claws 32 to move toward each other through the connecting plate 1 355, so that the outer clamping claws 32 are against the oil pan 10. 0 is clamped and fixed externally, and the connecting plate 355 moving toward each other pushes the L-shaped inner support plate 36 to move away from the groove frame 351 through the linkage rod 357, so that the L-shaped inner support plate 36 supports the side of the oil pan 10 close to the pouring and riser 101 internally. When the L-shaped inner support plate 36 moves, it drives the push plate 345 to move, and the second slider 346 is used to push the scissor frame 342 to expand outward, so that the inner clamping claws 33 clamp and fix the oil pan 10 internally.

[0057] Step 3, the electric push rod retracts inward to release the positioning of the oil pan 10, and then the mechanical arm 2 drives the mounting plate 31 to move upward to lift the oil pan 10 up, and then the mechanical arm 2 drives the mounting plate 31 to rotate 90° clockwise to move the mounting plate 31 to the top of the supporting seat 51. At this time, the T-shaped block 75 is just above the bell mouth 73, and then the mechanical arm 2 drives the mounting plate 31 to move downward. At this time, the T-shaped block 75 enters the T-shaped slot 72 under the guidance of the bell mouth 73, and the T-shaped slot 72 is used to guide and limit the T-shaped block 75 to prevent the mounting plate 31 from shifting forward, backward, left and right during the downward movement. When the T-shaped block 75 moves to the bottom end of the T-shaped slot 72, the bottom of the oil pan 10 is placed in the groove at the top of the supporting seat 51, and the plug-in block 37 is fully inserted into the plug-in slot 52.

[0058] Step 4. When the plug-in block 37 is inserted into the plug-in slot 52, the plug-in block 37 will first push the first wedge block 53 to retract into the interior of the supporting seat 51, so that the first wedge block 53 compresses the first compression spring 54. When the plug-in block 37 is completely inserted into the plug-in slot 52, the groove 371 is aligned with the first wedge block 53. At this time, the rebound force of the first compression spring 54 is used to push the first wedge block 53 into the groove 371, and the plug-in block 37 and the supporting seat 51 are locked together, so that the oil pan 10, the clamping mechanism 3 and the supporting mechanism 5 can move stably and linearly as a whole.

[0059] Step 5. When the oil pan 10 is placed into the groove at the top of the supporting seat 51, the pouring riser 101 is just lowered into the supporting groove 62. When entering the supporting groove 62, the pouring riser 101 will first push the third wedge block 63 to move to the left, so that the third wedge block 63 retracts into the supporting seat 2 61. When the pouring riser 101 is completely placed in the supporting groove 62, the rebound force of the second compression spring 65 is used to push the third wedge block 63 to move to the right, so that the third wedge block 63 blocks the top of the pouring riser 101, so that the supporting seat 2 61 supports and fixes the pouring riser 101.

[0060] Step six, push the mounting plate 31 backward through the robot arm 2, and then the mounting plate 31 pushes the supporting seat 51 backward through the outer clamping claw 32 and the plug-in block 37, and the supporting seat 51 drives the movable block 42 to move backward along the guide groove 41, and when the movable block 42 moves backward, it will drive the supporting seat 2 61 to move backward synchronously, ensuring that the pouring head 101 and the oil pan 10 always maintain a relatively stable state during cutting, and the movable block 42 will compress the reset spring 1 43 during the process of moving backward, and use the guide groove 41 to guide the movable block 42 to improve the stability of the oil pan 10 when moving backward for cutting.

[0061] Step seven, when the support seat 1 51 and the support seat 2 61 drive the oil pan 10 and the pouring riser 101 to pass through the saw blade, the saw blade is used to cut the connection between the oil pan 10 and the pouring riser 101. During the movement of the saw blade, the guide wheel 12 is used to clamp the saw blade to improve the stability of the saw blade during cutting.

[0062] Step 8: After the saw blade completely cuts and separates the oil pan 10 and the pouring riser 101, the robot arm 2 continues to push the support seat 51 backward until it contacts the stopper 557, and uses the stopper 557 to push the second wedge block 554 to retract into the inside of the support seat 51, so that the second wedge block 554 pushes the movable plate 551 to move downward, and then the movable plate 551 pulls the first wedge block 53 to retract into the inside of the support seat 51 through the pull rope 553, unlocks the plug-in block 37, and then pushes the push-pull plate 64 to move left, so that the third The wedge block 63 releases the limit fixation on the pouring riser 101, and then the pouring riser 101 is taken out of the supporting groove 62. Then the robot arm 2 drives the mounting plate 31 to move upward, and the cut oil pan 10 is taken out of the supporting seat 51. Then the robot arm 2 drives the clamping mechanism 3 to rotate 90° clockwise to transfer the oil pan 10 to the conveyor 2 9. When the oil pan 10 is separated from the supporting seat 51, the rebound force of the reset spring 43 is used to push the movable block 42 forward to reset the supporting mechanism 5 and the supporting mechanism 2 6.

[0063] Step 9, after the clamping mechanism 3 places the oil pan 10 on the conveyor 2 9, the driving motor 354 drives the bidirectional lead screw 352 to rotate in the opposite direction, so that the two third sliders 353 move away from each other, and then the third slider 353 drives the outer clamping claws 32 to move away from each other through the connecting plate 1 355 to release the outer clamping of the oil pan 10. At the same time, when the connecting plate 1 355 moves away from each other, it drives the connecting plate 2 356 to move toward the direction close to the groove frame 351, so that the connecting plate 2 356 drives the L-shaped inner support plate 36 to move toward the direction close to the groove frame 351, so that the L-shaped inner support plate 36 no longer clamps the oil pan 1 0 is supported by the inner wall of the L-shaped inner support plate 36, and at the same time, the L-shaped inner support plate 36 drives the scissor frame 342 to retract inwardly through the second slider 346, and then the scissor frame 342 drives the two inner clamping claws 33 to move toward each other, releasing the inner clamping of the oil pan 10, and placing the oil pan 10 on the conveyor 2 9, and then the robot arm 2 drives the mounting plate 31 to move upward to separate the outer clamping claw 32 and the inner clamping claw 33 from the oil pan 10, and then the conveyor 2 9 drives the oil pan 10 to transport the material to the right, and finally the robot arm 2 drives the mounting plate 31 to rotate 180° clockwise to move the clamping mechanism 3 back to the conveyor 1 8.
