Description

Technical Field

[0001] This invention relates to the field of engine cylinder head cutting technology, specifically to a cutting device for processing engine cylinder heads. Background Technology

[0002] The engine cylinder head is a key component mounted on top of the cylinder block, sealing the cylinder from above and forming the combustion chamber. It has core functions such as sealing the cylinder, forming the combustion chamber, guiding intake and exhaust, supporting the valve train, and dissipating heat (through an internal water jacket). Common materials are aluminum alloy (lightweight, good thermal conductivity, mostly used in gasoline engines) or cast iron (high strength, high temperature resistance, mostly used in diesel engines).

[0003] Existing technologies mostly use a unidirectional clamping plate for rigid pressure clamping, which easily leads to uneven force distribution. During the cutting process, the engine cylinder head is prone to slippage, shaking, or slight deflection due to saw blade vibration and cutting force, resulting in deviations in cutting dimensions, poor cut surface flatness, and difficulty in effectively guaranteeing processing accuracy.

[0015] The present invention has the following beneficial effects:

[0016] This invention features a cutting feed device that uses a motor, threaded rod, sliding groove, moving frame, and pulleys to achieve synchronous position adjustment between the cylinder head and the cutting mechanism. The second telescopic rod and the telescopic rod ensure smooth and unbiased movement, effectively improving the cutting position accuracy of the engine cylinder head. Simultaneously, a servo unidirectional electric push rod and guide telescopic rod are used to achieve precise feeding of the saw band cutting device. Combined with a sliding rod and spring plate, a flexible buffer structure is formed. If excessive compression occurs during cutting, the saw band cutting device can automatically retract and reset, preventing impact damage to the cutting mechanism. This invention is suitable for the cutting feed requirements of engine cylinder heads of different specifications.

[0017] This invention features a clamping adjustment device. A second motor and a second threaded rod drive the clamping rod to link with the extrusion plate for automatic centering and clamping. An elastic buffer clamping structure is formed by an elastic rod, a guide moving rod, and a rubber pad, which can adaptively conform to the irregular surface of the engine cylinder head, avoiding cylinder head extrusion deformation and surface scratches caused by rigid clamping. At the same time, a double clamping structure of lateral and top clamping is formed by the inclined plate linking with the pressure plate, firmly locking the cylinder head position and preventing workpiece displacement and shaking during the cutting process, thus significantly reducing cutting errors.

[0018] This invention uses a third motor to drive the cutting support plate to rotate on the support rod, which can flexibly adjust the tilt angle and placement posture of the engine cylinder head. It can complete the cutting of different end faces and corners of the cylinder head without manual re-clamping and positioning, adapting to the complex contours of the engine cylinder head and multi-position cutting conditions, and significantly improving the processing versatility and operation convenience.

[0019] This invention adds an integrated chip collection device, allowing chips to fall directly into the chip collection box below during cutting operations for real-time collection. This prevents metal chips from scattering on the workbench, contaminating the processing environment, and scratching the workpiece surface. The clamping rod moves in conjunction with the limiting rod and the shovel plate, which slide back and forth within the collection box to automatically push and compact the scattered chips, significantly increasing the chip storage capacity of the collection box and reducing the frequency of emptying. With the help of guide grooves, guide pulleys, and retractable rods, the chip collection box can be pulled out and moved. Later, chip removal and maintenance can be quickly carried out through the cleaning door, making the operation highly convenient.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1 - Figure 8 As shown, the present invention is a cutting device for processing engine cylinder heads, including a cutting base 1, a bracket 2 fixedly connected to the surface of the cutting base 1, a cutting feed device 3 provided on the surface of the cutting base 1, a clamping adjustment device 4 provided on the surface of the cutting base 1, and a debris collection device 5 provided on the surface of the cutting base 1.

[0034] The cutting feed device 3 includes a motor 20. The surface of the motor 20 is fixedly connected to the inner wall of the support 2. A threaded rod 21 is fixedly connected to the output end of the motor 20. When the threaded rod 21 rotates, it drives the moving frame 26 and the pulley 23 to move closer or further apart through the thread. When the moving frame 26 moves, it drives the cutting support plate 28 to move together through the support rod 27, thereby causing the machine to move the position of the engine cylinder head to be processed. A sliding groove 22 is opened on the inner wall of the cutting base 1. A pulley 23 is slidably connected to the inner wall of the sliding groove 22. A telescopic rod 24 is fixedly connected to the inner wall of the sliding groove 22. A second telescopic rod 25 is fixedly connected to the inner wall of the sliding groove 22. The inner wall of the 2 is slidably connected to a movable frame 26. The end of the movable frame 26 is fixedly connected to a support rod 27. The inner wall of the support rod 27 is rotatably connected to a cutting support plate 28. The end of the pulley 23 is fixedly connected to a long plate 29. The long plate 29 will drive the fixed support plate 31 and the limiting slide plate 33 to move through the circular telescopic rod 30. This will cause the fixed support plate 31 to drive the saw band cutting device 35 to move towards the engine cylinder head position through the servo one-way electric push rod 32, making the machine more stable when cutting and feeding. The surface of the long plate 29 is fixedly connected to a circular telescopic rod 30. The end of the circular telescopic rod 30 away from the long plate 29 is fixedly connected to a fixed support plate 31.

[0035] A servo unidirectional electric actuator 32 is fixedly connected to the inner wall of the fixed support plate 31. A saw band cutting device 35 is fixedly connected to the output end of the servo unidirectional electric actuator 32. When the saw band cutting device 35 contacts the engine cylinder head, if excessive compression occurs, it will slide inside the elongated plate 29 through the slide rod 36, causing the saw band cutting device 35 to move backward, thus avoiding damage to the saw band cutting device 35 due to excessive compression. A limit slide plate 33 is fixedly connected to the top of the fixed support plate 31. A guide telescopic rod 34 is fixedly connected to the inner wall of the limit slide plate 33. A slide rod 36 is fixedly connected to the surface of the fixed support plate 31. A spring plate 37 is fixedly connected to the end of the slide rod 36 away from the fixed support plate 31.

[0036] The surface of the threaded rod 21 is threadedly connected to the inner wall of the movable frame 26, the surface of the threaded rod 21 is threadedly connected to the inner wall of the pulley 23, the end of the telescopic rod 24 away from the slide groove 22 is fixedly connected to the surface of the pulley 23, and the end of the second telescopic rod 25 away from the slide groove 22 is fixedly connected to the surface of the movable frame 26.

[0037] The limiting slide plate 33 is located above the fixed support plate 31. The end of the guide telescopic rod 34 away from the limiting slide plate 33 is fixedly connected to the end of the saw band cutting device 35. The end of the spring plate 37 away from the slide rod 36 is fixedly connected to the surface of the elongated plate 29.

[0038] The clamping adjustment device 4 includes a support frame 40, the surface of which is fixedly connected to the surface of the cutting support plate 28. A second motor 41 is fixedly connected to the inner wall of the support frame 40. A second threaded rod 42 is fixedly connected to the output end of the second motor 41. A force-applying plate 43 is threadedly connected to the surface of the second threaded rod 42. A clamping rod 44 is fixedly connected to the inner wall of the force-applying plate 43 away from the second threaded rod 42. A slot 45 is provided on the inner wall of the cutting support plate 28. A pressing plate 46 is fixedly connected to the end of the clamping rod 44. When the pressing plate 46 moves, it will press the guide moving rod 47 through the elastic rod 49, thereby driving the rubber pad 48 to move together, so that the rubber pad 48 clamps and fixes the engine cylinder head. The guide moving rod 4 is slidably connected to the inner wall of the pressing plate 46. 7. A rubber pad 48 is fixedly connected to the end of the guide moving rod 47. When the rubber pad 48 squeezes the engine cylinder head, it will stretch the elastic rod 49 through the guide moving rod 47 to avoid problems such as deformation of the engine cylinder head due to excessive compression. When the rubber pads 48 approach each other, they will drive the fixed pressure plate 51 to move together through the squeezing inclined plate 50, so that the fixed pressure plate 51 can stabilize the engine cylinder head. The end of the guide moving rod 47 away from the rubber pad 48 is fixedly connected to the elastic rod 49. The surface of the rubber pad 48 is hinged to the inclined plate 50. The end of the inclined plate 50 away from the rubber pad 48 is hinged to the fixed pressure plate 51. The surface of the support rod 27 is fixedly connected to the support frame 52. The inner wall of the support frame 52 is fixedly connected to the third motor 53.

[0039] The surface of the clamping rod 44 is slidably connected to the inner wall of the slot 45, the guide moving rod 47 passes through the extrusion plate 46 and extends to the surface of the rubber pad 48, the end of the elastic rod 49 away from the guide moving rod 47 is fixedly connected to the surface of the extrusion plate 46, the fixed pressure plate 51 is located above the cutting support plate 28, and the output end of the third motor 53 is fixedly connected to the end of the cutting support plate 28.

[0040] The debris collection device 5 includes a ring plate 60, the end of which is fixedly connected to the bottom of the cutting support plate 28. A spring rod 61 is fixedly connected to the surface of the ring plate 60. A guide groove 62 is provided on the inner wall of the cutting support plate 28. A guide pulley 63 is slidably connected to the inner wall of the guide groove 62. The guide pulley 63 drives the debris collection box 65 to slide inside the guide groove 62, thereby moving the debris collection box 65 to the outer end of the cutting support plate 28, so that the debris remaining above the cutting support plate 28 falls into the debris collection box 65 for centralized collection. A retractable rod 64 is fixedly connected to the surface of the guide pulley 63. The debris collection box 65 is fixedly connected to the bottom of the guide pulley 63. A cleaning door 66 is provided on the inner wall of the debris collection box 65. A limit rod 67 is fixedly connected to the bottom of the clamping rod 44. A shovel plate 68 is slidably connected to the end of the limit rod 67 away from the clamping rod 44. A tension rod 69 is fixedly connected to the surface of the shovel plate 68.

[0041] The end of the retractable rod 64 away from the guide pulley 63 is fixedly connected to the inner wall of the guide groove 62. The debris collection box 65 is located below the cutting support plate 28. The bottom of the shovel plate 68 is in contact with the inner wall of the debris collection box 65. The end of the tension rod 69 away from the shovel plate 68 is fixedly connected to the inner wall of the debris collection box 65. The end of the spring rod 61 away from the ring plate 60 is fixedly connected to the surface of the debris collection box 65.

[0042] In operation, the motor 20, when its output is turned on, drives the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the moving frame 26 and pulley 23 to move closer or further apart via the thread. The moving frame 26, when moving, drives the cutting support plate 28 to move along with it via the support rod 27, thus moving the engine cylinder head to be processed. The second telescopic rod 25 makes the movement of the moving frame 26 more stable, preventing positional shifts that could affect the cutting accuracy of the engine cylinder head during cutting. Simultaneously, the movement of the pulley 23 drives the elongated plate 29 to move along with it. The elongated plate 29, via the circular telescopic rod 30, drives the fixed support plate 31 and the limiting slide plate 33 to move, thus causing the fixed support plate 31 to drive the saw band to cut via the servo unidirectional electric actuator 32. The cutting device 35 moves towards the engine cylinder head, making the cutting feed more stable. Simultaneously, the servo one-way electric actuator 32 opens its output end, causing the saw band cutting device 35 to move inside the limit slide plate 33, thus enabling the machine to perform the cutting operation. The guide telescopic rod 34 further stabilizes the saw band cutting device 35 when cutting the engine cylinder head. If excessive pressure occurs when the saw band cutting device 35 contacts the engine cylinder head, it will slide backward through the slide rod 36 inside the elongated plate 29, preventing damage from excessive pressure. At the same time, the spring plate 37 will reset the saw band cutting device 35 after it completes the cutting operation, facilitating machine operation. In the next operation, when the second motor 41 is turned on, its output end drives the second threaded rod 42 to rotate. The rotation of the second threaded rod 42 causes the force plate 43 to move via the thread. The movement of the force plate 43 causes the clamping rod 44 to move inside the slot 45, thus pushing the extrusion plate 46 above the cutting support plate 28. As the extrusion plate 46 moves, it presses the guide moving rod 47 via the elastic rod 49, causing the rubber pad 48 to move as well. This clamps and fixes the engine cylinder head, preventing cutting errors due to cylinder head misalignment during cutting. Simultaneously, when the rubber pad 48 presses the engine cylinder head, it stretches the elastic rod 49 via the guide moving rod 47, preventing excessive pressure. When compression causes deformation of the engine cylinder head, the rubber pads 48 move closer together, causing the fixed pressure plate 51 to move along with the compression plate 50. This stabilizes the engine cylinder head, preventing the machine from shifting backward during cutting and affecting normal operation. When the third motor 53 is turned on, its output drives the cutting support plate 28 to rotate inside the support rod 27, allowing the machine to fully adjust the angle of the engine cylinder head for more precise cutting. When the elongated plate 29 contacts the debris collection box 65, its continued movement compresses the debris collection box 65, causing the guide pulley 63 to move within the guide groove 62, ensuring the debris collection box 65 is positioned correctly for cutting.To facilitate the collection of debris generated during cutting, the debris collection box 65 is designed to collect the debris. Simultaneously, when the clamping rod 44 moves, it drives the shovel plate 68 to move within the debris collection box 65 via the limiting rod 67. This allows the shovel plate 68 to compress the debris inside the box, increasing the machine's debris collection capacity. The tension rod 69 ensures greater stability during the movement of the shovel plate 68. After cutting, the cutting support plate 28 rotates, causing the debris collection box 65 to slide within the guide groove 62 via the guide pulley 63. This moves the debris collection box 65 to the outer end of the cutting support plate 28, allowing any remaining debris above the cutting support plate 28 to fall into the collection box 65 for centralized collection. The spring rod 61 limits the movement of the debris collection box 65 to prevent interference with the machine's debris collection during cutting.
