Description

Technical Field

[0001] This invention belongs to the field of workpiece processing equipment technology, specifically a crankshaft processing production line. Background Technology

[0002] In an engine, the crankshaft is the part that converts rotary motion into linear motion, or vice versa. It is an important component in reciprocating engines, shearing machines, compressors, and stamping machinery. Crankshaft workpieces need to undergo milling, drilling, and grinding operations, which requires placing the crankshaft workpiece in a CNC machining center for processing by multiple cutting heads.

[0003] When performing systematic machining of crankshafts, existing machining equipment requires systematic testing after the crankshaft is machined. This results in wasted machining time and severely impacted work efficiency if the detected crankshaft eccentricity is off or if the spindle is deformed or damaged. Furthermore, it increases production losses and makes adjustments more complicated. Therefore, improvements are needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a crankshaft machining production line, comprising a container outer casing, a fastening device, a suspension component, and a cutting component. The fastening device is disposed inside the container outer casing, and a crankshaft to be machined is installed inside the fastening device. The suspension component is disposed at the bottom of the inner wall of the container outer casing, and the cutting component is disposed inside the container outer casing. The suspension components include a carrier pivot, a sleeve clamp, a sensing slide arm, a guide slide, and a spring connecting rod. The upper and lower ends of the elastic connecting column are respectively inserted into the outer surfaces of the upper and lower sensing sliding arms, and the outer surface of the bottom sensing sliding arm is slidably connected to the inner wall of the guide sliding shell. The bottom end of the guide sliding shell is inserted into a container bottom plate. The bottom of the outer surface of the container shaft is inserted into the top of the top sensing slide arm. The bottom of the sleeve gripper is rotatably connected to the outer surface of the container shaft, and the inner wall of the sleeve gripper is fitted with a lubricated inner sleeve. The guide housing pushes the rod body assembled with the two sensing slide arms and the elastic connecting column upward through the internal pusher. Then the container shaft twists the sleeve grippers on both sides, merging the sleeve grippers on the outer surface of the main shaft of the machining crankshaft. After the sensing slide arm is pushed upward by the pusher inside the guide housing, the pusher restricts the bottom sensing slide arm to a fixed height. When the sleeve gripper fitted on the outer surface of the machining crankshaft slides vertically, it pulls the elastic connecting column and the top sensing slide arm, thereby subjecting the sensing slide arm to changing pressure and tension, so that the sensing slide arm feeds back the signal to the side control panel.

[0005] Furthermore, the outer container includes: A protective outer shell, wherein a through groove is provided on the front side of the protective outer shell; The side control panels are symmetrically arranged on both sides of the outer surface of the protective housing. The side control panels contain signal transmitters and signal receivers for controlling the internal devices. A closed rotating cover is provided, with its outer surface set in the through-hole groove of the protective shell via a rotating shaft.

[0006] Furthermore, the fastening device includes: A rotary motor, wherein the outer surface of the motor housing is fixedly connected to the inner wall of the protective outer shell; The inner control cylinder has fastening claws evenly arranged on its outer surface, and anti-slip pads are fixedly connected to the inner wall of the fastening claws. The inner control cylinder is rotated by the control shaft of the rotary motor, thereby driving the clamped machining crankshaft to rotate.

[0007] Furthermore, the cutting component includes: The guide rail has symmetrical sliding arms inserted into both sides of its outer surface, and the outer surface of the sliding arms is sleeved with the inner wall of the protective shell. The part of the sliding arm away from the guide rail is a fixed part, and there is a traction mechanism with a retractable connecting rod inside, which drives the front part and the guide rail to slide in a direction. A side-push sleeve, wherein a hollow compression tube is inserted at the axial center of the inner cavity of the side-push sleeve; A deflection plate is provided, with a motor shaft rotatably connected to its bottom end. The outer surface of the motor shaft is inserted into the end of the hollow compression tube away from the side push sleeve. The side push sleeve pushes the motor shaft at the bottom of the deflection plate to slide along the inner wall of the guide rail by pressurizing the inside of the hollow compression tube. The motor shaft can twist the deflection plate around the inner wall of the guide rail.

[0008] Furthermore, the cutting component also includes: A cutting motor, wherein a cutting disc is fitted onto the outer surface of the cutting motor shaft; An infrared ranging ring is provided, the outer surface of which is sleeved with the middle of the outer surface of the cutting disc. The infrared ranging ring detects the distance between the cutting disc and the crankshaft being processed by emitting infrared rays, thereby avoiding over-cutting by the cutting disc.

[0009] Furthermore, it also includes: An internal cleaning component, located at the bottom of the cutting component, is used to remove floating dust from inside the protective housing; The saw disc cleaning component is located on the inner wall of the protective housing and is used to clean iron filings from the outer surface of the saw disc.

[0010] Furthermore, the internal cleaning component includes: The bottom shell is fitted with the bottom of the inner wall of the protective shell; The outer surface of the wall-mounted sliding plate is slidably connected to the top of the inner wall of the bottom shell, and a rubber sealing strip is inserted into the outer surface of the wall-mounted sliding plate. The upper plate has its bottom inserted into the middle of the upper surface of the wall-mounted sliding plate, and its top sleeved with the outer surface of the guide rail.

[0011] Furthermore, the internal cleaning component also includes: An inverted suction plate is symmetrically arranged on both sides of the upper surface of the upper plate, and the air inlet of the inverted suction plate extends to the outside of the upper plate through a groove. The main purification box has its outer surface fixedly connected to the inner wall of the bottom shell, and its upper surface is evenly provided with adsorption mesh holes. The impurities adsorbed by the main purification box will gather in the adsorption mesh holes on its top. When the wall-mounted sliding plate moves to the top of the main purification box, the inverted suction plate can extract the impurities inside the adsorption mesh holes.

[0012] Furthermore, the saw disc cleaning component includes: The suspension box has an outer surface that is snapped into the inner wall of the protective shell, and an expansion opening is provided in the middle of the inner cavity of the suspension box. A propulsion net cover is provided, and a magnetic outer plate is inserted into the outer surface of the propulsion net cover on the side near the suspension box. The outer surface of the magnetic outer plate is inserted into the middle of the inner cavity of the suspension box through an expansion port. A rubber strap is inserted at one end into the outer surface of the magnetic outer plate, and at the other end into the inner cavity of the expansion port. When the push net slides from the expansion port toward the side closer to the cutting component, its magnetic outer plate will still completely cover the expansion port of the suspension box, and the airflow adsorbed from the push net will enter the interior of the suspension box.

[0013] Furthermore, the saw disc cleaning component also includes: An internal suction plate is provided, the outer surface of which is inserted into the side of the suspension box cavity away from the cutting component. A filter screen, the outer surface of which is sleeved with the air inlet of the built-in suction plate; The electromagnetic plate is symmetrically arranged on the upper and lower sides of the outer surface of the built-in suction plate. The built-in suction plate is connected to the inner cavity of the electromagnetic plate through a connecting wire. After the built-in suction plate supplies power to the electromagnetic plate, the electromagnetic plate can push the magnetic outer plate and the propulsion mesh towards the side closer to the cutting part through magnetic repulsion.

[0014] The beneficial effects of this invention are as follows: 1. This device can perform turning on crankshaft blanks placed inside the outer casing and clamped by a fastening device. During the machining process, the suspension components clamp the main shaft of the crankshaft through the sleeve jaws. Without interfering with the crankshaft's rotation, when the crankshaft main shaft's eccentricity deviates due to quality issues, the sensing slide arm fixed at a predetermined height is subjected to tension or pressure, which is then fed back to the side control plate, thereby terminating the machining work in time. This saves time wasted on subsequent machining of defective crankshafts, effectively improving production efficiency, optimizing the production process, and reducing production losses.

[0015] 2. The device is equipped with an infrared ranging ring on the side of the cutting disc for constant distance measurement. When the deflection plate drives the cutting motor to rotate, it can ensure that the landing point of the cutting disc is relatively accurate, thereby avoiding the problem of the cutting disc cutting the connecting shaft of the crankshaft and causing damage to the crankshaft structure. The guide rail itself can be pushed and moved in a directional manner by the sliding arm, so when the processed crankshaft is taken out, it can ensure that the cutting disc is far away from the operator, thereby avoiding the problem of the cutting disc causing cutting injury to the operator's hands.

[0016] 3. After the crankshaft inside the protective housing is machined, if the sealed cover is opened immediately, the floating dust and impurities diffused inside the protective housing will float out and pollute the surrounding environment. Therefore, a main purification box is set up inside the protective housing for adsorption and purification. The main purification box is optimized so that the floating dust adsorbed by the main purification box can be transferred to the inside of the holding shell through a moving inverted suction plate, thereby clearing the adsorption mesh and extending the continuous working time of the adsorption mesh. At the same time, it avoids the problem of the main purification box failing to work properly due to the debris splashed during turning clogging the adsorption mesh.

[0017] 4. After the cutting components finish their work, the built-in suction plate performs air suction, allowing the debris attached to the outer surface of the cutting disc to enter the suspension box through the mesh groove of the push-beam cover. This cleans the debris and impurities attached to the tooth surface and outer surface of the cutting disc. The debris is eventually collected inside the suspension box for recycling. Since the push-beam cover is extended to approach the cutting disc, it is far away from the cutting components when not in operation, so it will not interfere with the movement and operation of the cutting components.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] Example 1, please refer to Figures 1-4 This invention provides a technical solution: a crankshaft machining production line, comprising a container outer casing 1, a fastening device 2, a suspension component 3, and a cutting component 4. The fastening device 2 is disposed inside the container outer casing 1, and a crankshaft 21 to be machined is installed inside the fastening device 2. The suspension component 3 is disposed at the bottom of the inner wall of the container outer casing 1, and the cutting component 4 is disposed inside the container outer casing 1. Suspension component 3 includes a carrier pivot 35, a sleeve clamp 36, a sensing slide arm 33, a guide slide 32, and a spring connecting rod 34. The upper and lower ends of the elastic connecting column 34 are respectively inserted into the outer surfaces of the upper and lower sensing sliding arms 33, and the outer surface of the bottom sensing sliding arm 33 is slidably connected to the inner wall of the guide sliding shell 32. The bottom end of the guide sliding shell 32 is inserted into the container bottom plate 31. The bottom of the outer surface of the container shaft 35 is inserted into the top of the top sensing slide arm 33. The bottom of the sleeve gripper 36 is rotatably connected to the outer surface of the container shaft 35, and the inner wall of the sleeve gripper 36 is fitted with a lubricating inner sleeve 37. The guide slide 32 pushes the rod body assembled with the two sensing slide arms 33 and the elastic connecting column 34 upward through the internal pusher. Then the container shaft 35 twists the sleeve grippers 36 on both sides, merging the sleeve grippers 36 on the outer surface of the main shaft of the machining crankshaft 21. After the sensing slide arm 33 is pushed upward by the pusher inside the guide slide 32, the pusher restricts the bottom sensing slide arm 33 to a fixed height. When the sleeve gripper 36 fitted on the outer surface of the machining crankshaft 21 slides vertically, it will pull the elastic connecting column 34 and the top sensing slide arm 33, so that the sensing slide arm 33 is subjected to changing pressure and tension, so that the sensing slide arm 33 feeds back the signal to the side control plate 12.

[0022] Container outer box 1 includes: The protective housing 11 has a through groove on its front side; Side control panels 12 are symmetrically arranged on both sides of the outer surface of the protective housing 11. The side control panels 12 are equipped with signal transmitters and signal receivers for controlling the internal devices. The outer surface of the closed rotating cover 13 is set in the through groove of the protective shell 11 via a rotating shaft.

[0023] Fastening device 2 includes: The outer surface of the housing of the rotary motor 22 is fixedly connected to the inner wall of the protective housing 11; The inner cylinder 23 is controlled, and fastening claws 24 are evenly arranged on the outer surface of the inner cylinder 23. Anti-slip pads 25 are fixedly connected to the inner wall of the fastening claws 24. The rotating motor 22 controls the inner cylinder 23 to rotate, thereby driving the clamped machining crankshaft 21 to rotate.

[0024] Cutting component 4 includes: The guide rail 41 has symmetrical sliding arms 42 inserted into both sides of its outer surface. The outer surface of the sliding arms 42 is sleeved with the inner wall of the protective shell 11. The part of the sliding arm 42 away from the guide rail 41 is a fixed part with a traction mechanism of retractable connecting rod inside, which drives the front part and the guide rail 41 to slide in a direction. A side-push sleeve 43, with a hollow compression tube 44 inserted into the axial center of the inner cavity of the side-push sleeve 43; The deflection plate 45 has a motor shaft rotatably connected to its bottom end. The outer surface of the motor shaft is inserted into the end of the hollow compression tube 44 away from the side push sleeve 43. The side push sleeve 43 pressurizes the inside of the hollow compression tube 44 to push the motor shaft at the bottom of the deflection plate 45 to slide along the inner wall of the guide rail 41. The motor shaft can rotate the deflection plate 45 around the inner wall of the guide rail 41.

[0025] Cutting component 4 also includes: A cutting motor 46 has a cutting disc 47 sleeved on the outer surface of its shaft. Infrared ranging ring 48, the outer surface of infrared ranging ring 48 is sleeved with the middle of the outer surface of cutting disc 47. Infrared ranging ring 48 detects the distance between cutting disc 47 and the machining crankshaft 21 by emitting infrared light, so as to avoid excessive cutting by cutting disc 47.

[0026] Open the closed rotating cover 13, clamp and fix the crankshaft to be processed by the fastening device 2, control the inner cylinder 23 to retract the outer fastening jaws 24, so that the fastening jaws 24 contact the end of the crankshaft through the anti-slip pads 25 to clamp it. During processing, the rotary motor 22 will drive the inner cylinder 23 to rotate centrifugally.

[0027] After the crankshaft is set up, the suspension component 3 located directly below the crankshaft starts to work, guiding the sliding housing 32 to slide up the sleeve clamp 36. Then, the sleeve clamp 36 clamps the main shaft part connected to the machining crankshaft 21. When the machining crankshaft 21 rotates, if the main shaft of the machining crankshaft 21 is completely deformed, the machining crankshaft 21 will definitely drive the sleeve clamp 36 to move vertically when rotating. At this time, the sensing sliding arm 33, which is fixed at a predetermined height, is subjected to tension or pressure, which is fed back to the side control plate 12. This indicates that the main shaft of the machining crankshaft 21 is twisted and is a defective product, which does not need to be processed further. At this time, the machining work can be stopped and the crank can be replaced for further processing.

[0028] When the cutting component 4 is working, its sliding arm 42 pushes the guide rail 41 and the side push sleeve 43 to move closer to the crank. Then, the deflection plate 45 twists the cutting motor 46, so that the cutting disc 47 of the cutting motor 46 is inserted into the lower cutting point of the crank. Then, the cutting motor 46 rotates the cutting disc 47 to cut the crank. During the flipping process of the deflection plate 45, the actual distance between the cutting disc 47 and the lower cutting point of the crank is measured by the infrared ranging ring 48, thereby avoiding the cutting disc 47 from cutting the crank connecting rod.

[0029] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, it further includes: The internal cleaning component 5 is located at the lower part of the cutting component 4 and is used to remove floating dust inside the protective shell 11. The saw disc cleaning component 6 is located on the inner wall of the protective housing 11 and is used to clean iron filings from the outer surface of the cutting disc 47.

[0030] Internal cleaning component 5 includes: The bottom surface of the bottom shell 51 is engaged with the bottom of the inner wall of the protective shell 11. The outer surface of the wall-mounted sliding plate 53 is slidably connected to the top of the inner wall of the bottom shell 51, and a rubber sealing strip 52 is inserted into the outer surface of the wall-mounted sliding plate 53. The upper plate 55 is inserted into the middle of the upper surface of the wall-mounted sliding plate 53 at its bottom, and the top of the upper plate 55 is sleeved with the outer surface of the guide rail 41.

[0031] The internal cleaning component 5 also includes: An inverted suction plate 54 is symmetrically arranged on both sides of the upper surface of the upper plate 55, and the air inlet of the inverted suction plate 54 extends to the outside of the upper plate 55 through a groove. The main purification box 56 has its outer surface fixedly connected to the inner wall of the bottom shell 51. The upper surface of the main purification box 56 is evenly provided with adsorption mesh 57. The impurities adsorbed by the main purification box 56 will gather in the adsorption mesh 57 on its top. When the wall-mounted sliding plate 53 moves to the top of the main purification box 56, the inverted suction plate 54 can extract the impurities inside the adsorption mesh 57.

[0032] The saw blade cleaning component 6 includes: The suspension box 61 has an outer surface that is snapped into the inner wall of the protective shell 11, and an expansion opening is provided in the middle of the inner cavity of the suspension box 61. A propulsion cover 62 is provided, and a magnetic outer plate 63 is inserted into the outer surface of the propulsion cover 62 on the side near the suspension box 61. The outer surface of the magnetic outer plate 63 is inserted into the middle of the inner cavity of the suspension box 61 through an expansion port. The rubber strap 64 has one end inserted into the outer surface of the magnetic outer plate 63 and the other end inserted into the inner cavity of the expansion port. When the push net cover 62 slides from the expansion port to the side closer to the cutting component 4, its magnetic outer plate 63 will still completely cover the expansion port of the suspension box 61, and the airflow adsorbed from the push net cover 62 will enter the interior of the suspension box 61.

[0033] The saw blade cleaning component 6 also includes: Built-in suction plate 65, the outer surface of built-in suction plate 65 is inserted into the side of the inner cavity of suspension box 61 away from cutting part 4; The filter screen 67 has its outer surface fitted with the air inlet of the built-in suction plate 65. The electromagnetic plate 66 is symmetrically arranged on the upper and lower sides of the outer surface of the built-in suction plate 65. The built-in suction plate 65 is connected to the inner cavity of the electromagnetic plate 66 through a plug-in wire. After the built-in suction plate 65 supplies power to the electromagnetic plate 66, the electromagnetic plate 66 can push the magnetic outer plate 63 and the push net cover 62 towards the side closer to the cutting component 4 through magnetic repulsion.

[0034] During operation, as the guide rail 41 is propelled forward by the sliding arm 42, the guide rail 41 moves forward via the upper clamping plate 55, causing the wall-mounted sliding plate 53 to slide forward. At this time, the upper surface of the housing bottom shell 51 is completely sealed by the wall-mounted sliding plate 53 and the rubber sealing strip 52, and the internal cleaning component 5 does not operate. After the crank is processed, the cutting disc 47 and the crankshaft 21 are stopped from rotating. Then, the guide rail 41 is pulled backward via the sliding arm 42. At this time, the guide rail 41 moves backward via the upper clamping plate 55, causing the wall-mounted sliding plate 53 to slide backward. The adhesive tape 52 is compressed, exposing the adsorption mesh 57 on the upper part of the main purification box 56. Then, the main purification box 56 sucks away the impurities diffused in the protective shell 11 through the adsorption mesh 57, achieving a purification effect. When the crankshaft 21 is processed next, the wall-mounted sliding plate 53 will cover the upper surface of the main purification box 56 again as the upper plate 55 moves. Then, the inverted suction plate 54 sucks away the impurities accumulated inside the adsorption mesh 57. When the wall-mounted sliding plate 53 moves later, the inverted suction plate 54 sprays the sucked impurities downward, thereby transferring the impurities into the storage bottom shell 51.

[0035] After the cutting component 4 finishes its work, the deflection plate 45 will twist the cutting motor 46 backward, causing the cutting disc 47 to move away from the crankshaft. At this time, the cutting disc 47 is closer to the saw disc cleaning component 6. Then the saw disc cleaning component 6 starts to work. After the built-in suction plate 65 energizes the electromagnetic plates 66 on both sides, the electromagnetic plates 66 move the magnetic outer plate 63 and the pusher cover 62 closer to the cutting disc 47 through repulsion. Then the built-in suction plate 65 performs air suction, allowing the debris attached to the outer surface of the cutting disc 47 to enter the suspension box 61 through the mesh groove of the pusher cover 62. However, due to the obstruction of the filter plate 67, the debris will not enter the interior of the built-in suction plate 65.

[0036] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
