Description

Technical Field

[0001] The present invention relates to the field of cutting technology, in particular to a cutting device for machining a gearbox shaft with a clamping function. Background Art

[0002] The cutting device for gearbox shaft processing is a special equipment used for precision cutting of gearbox shafts. It is usually integrated into CNC machine tools or automated production lines to meet the high-precision and high-efficiency processing requirements of shaft parts in the fields of automobiles and mechanical manufacturing. The existing cutting device uses traditional chucks or universal fixtures to clamp the shafts. The limitations of the end faces of ordinary chucks and the length limitations of the machine make the cutting device suitable for clamping short raw material shafts. After cutting, the shaft needs to be replaced or re-clamped. Multiple cutting and blanking cannot be performed in one clamping and positioning, which reduces the efficiency of sawing and blanking. Summary of the Invention

[0003] The object of the present invention is to provide a cutting device for machining a gearbox shaft with a clamping function, so as to solve the problems raised in the prior art.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a cutting device for processing a gearbox shaft with a clamping function, comprising a machine platform, a lifting plate, a cutting machine, a fixed clamping module, a movable clamping module and an electric chuck, wherein the lifting plate is arranged on the machine platform, the cutting machine is mounted on the lifting plate through a servo drive module, the fixed clamping module is mounted on the machine platform, the movable clamping module is slidably mounted on the side of the machine platform away from the lifting plate, the electric chuck is mounted on the side of the machine platform close to the lifting plate, the fixed clamping module, the movable clamping module and the electric chuck clamp the shaft, and the cutting machine cuts the shaft.

[0005] Furthermore, the fixed clamping module includes an assembly block, a center half gear ring, a first half gear ring and a second half gear ring. The center half gear ring, the first half gear ring and the second half gear ring are all half-annular external meshing gears of the same shape. The first half gear ring and the second half gear ring are arranged on both sides of the center half gear ring. A transfer groove is opened in the assembly block. The depth of the transfer groove is greater than the contour radius of the center half gear ring. The center half gear ring, the first half gear ring and the second half gear ring are rotatably installed in the transfer groove. Before cutting the shaft rod, the control system controls the movement of the servo drive module and adjusts the position of the movable clamping module on the machine according to the length of the shaft rod. The operator uses the overhead lifting device to move the shaft rod to be sawed above the machine platform so that the shaft rod falls between the fixed clamping module and the movable clamping module.

[0006] Furthermore, a nut sleeve, a worm wheel, a worm and a first servo motor are provided inside the center half gear ring. The nut sleeve is rotatably installed inside the center half gear ring, the worm wheel is integrally arranged on the outside of the nut sleeve, and the worm is installed on the motor shaft of the first servo motor. The worm wheel and the worm are engaged for transmission.

[0007] Furthermore, a screw and a clamping block are provided at the inner ring of the center half gear ring, and the screw passes through the interior of the center half gear ring, and a plurality of axially opened sliding grooves are provided on the screw, and the screw is slidably connected to the center half gear ring, and the screw is threadedly connected to the nut sleeve, and the clamping block is installed at the end of the screw away from the nut sleeve. In the initial state, the center half gear ring, the first half gear ring and the second half gear ring are all received in the assembly block, and the servo drive module enables the first half gear ring and the second half gear ring to slide along the dovetail slider on both sides of the center half gear ring. After the first half gear ring and the second half gear ring are unfolded, the tooth profiles of the center half gear ring, the first half gear ring and the second half gear ring form a complete outer and inner gear ring on the axial projection surface, and the three half gear rings have successive profile transitions. The wide-body gear can continuously drive the three half gear rings to rotate as a whole in the assembly block.

[0008] Furthermore, the structural settings on the first and second half gear rings are the same as those on the center half gear ring. An arc-shaped dovetail slider is provided on both sides of the center half gear ring. The curvature of the two dovetail sliders is the same as that of the center half gear ring. The first and second half gear rings are provided with dovetail grooves that match the dovetail sliders on the side close to the center half gear ring. The first and second half gear rings are slidably connected to the dovetail sliders on the center half gear ring through the dovetail grooves. A servo drive is provided at the connection between the first and second half gear rings and the center half gear ring. Module, while the first half gear ring and the second half gear ring are unfolded, the three clamping blocks are dispersed to positions 120° apart, and the first servo motors in all half gear rings are energized to drive the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the nut sleeve to rotate at the same time. Since the screw can only slide and cannot rotate, the screw extends outward under the drive of the nut sleeve, so that all the clamping blocks are against the shaft rod, and the shaft rod is clamped by using three clamping blocks at positions 120° apart, which plays a role in quickly positioning the shaft rod, and the open fixed clamping module and the movable clamping module are used to assemble and clamp the shaft rod, which is convenient for loading the shaft rod.

[0009] Furthermore, a slide groove is provided on the top of the machine, and the mobile clamping module is installed in the slide groove through a servo drive module. The structural setting mode of the mobile clamping module is the same as that of the fixed clamping module. After the fixed clamping module and the mobile clamping module clamp the shaft rod raw material, the electric chuck clamps the blanking end of the shaft rod. After cutting and blanking, the clamping block in the fixed clamping module releases the shaft rod, and the mobile clamping module drives the shaft rod to move, pushing the shaft rod out to a certain length for subsequent cutting. Compared with the end face limitation of the traditional chuck and the length limitation of the machine, the present invention is not only suitable for the clamping of short raw material shaft rods, but also more suitable for the clamping and positioning of long raw material shaft rods. Multiple cutting and blanking can be performed in one clamping and positioning, which improves the efficiency of sawing and blanking.

[0010] Furthermore, a pair of swing arms are rotatably installed inside the machine, and a transmission shaft is rotatably installed at the other end of the pair of swing arms. A motor bracket is provided on the swing arm away from the fixed clamping module, and a second servo motor is installed on the motor bracket. The transmission shaft is connected to the motor shaft of the second servo motor. An electromagnet is provided inside the machine, and the electromagnet is energized to adsorb the swing arm. During the sawing process, if the shaft rod is fixed, as the sawing depth increases, the stress of the circular saw blade is maximum when it cuts to the width of the shaft rod diameter, and the stress exceeds the width of the shaft rod diameter. Then it gradually decreases. The uneven sawing stress causes the deformation of the tool shaft and the wear of the circular saw blade. The electromagnet is energized to adsorb the two swing arms, and the swing arms drive the transmission shaft to move upward, so that the two wide-body gears are engaged with the half-toothed ring. The second servo motor drives the transmission shaft to rotate, and the transmission shaft drives the two wide-body gears to rotate. The wide-body gears drive the half-toothed ring to rotate, and the clamped shaft also rotates. The shaft body rotates during the cutting process. During the sawing process, the circular saw blade evenly cuts from the outside of the shaft to the axis center, reducing the cutting stress and effectively weakening the deformation of the shaft and the wear of the circular saw blade.

[0011] Furthermore, two wide-body gears are provided on the transmission shaft, one wide-body gear is fixedly mounted on the transmission shaft, and the other wide-body gear is slidably mounted on the transmission shaft, the fixedly mounted wide-body gear is meshed with the center half-tooth ring in the fixed clamping module, and two baffles are also installed at the bottom of the assembly block in the mobile clamping module, the slidingly mounted wide-body gear is restricted between the two baffles, and the slidingly mounted wide-body gear is meshed with the center half-tooth ring in the mobile clamping module, and when the mobile clamping module is displaced, the wide-body gear is driven to slide on the transmission shaft through the baffle, and even if the position of the mobile clamping module changes, the wide-body gear can still drive the half-tooth ring in the mobile clamping module to rotate.

[0012] Furthermore, the cutting machine includes a gearbox, which is slidably mounted on a lifting vertical plate. A main motor is provided on the top of the gearbox. The motor shaft of the main motor and the input end of the gearbox are both provided with pulleys. A V-belt is connected between the two pulleys. A circular saw blade is installed at the output end of the gearbox, and a protective cover that half-wraps the circular saw blade is also provided on the gearbox.

[0013] Furthermore, a positive discharge needle and a negative patch are provided inside the protective cover, and the positive discharge needle and the negative patch are connected to the control system through a circuit. After high voltage electricity is passed through the positive discharge needle and the negative patch, a strong electric field is formed between the two. The ionized air at the positive discharge needle moves toward the negative patch at a high speed. At the same time, the simple friction and collision of air molecules drive the gas flow around the ionized air, forming an ion wind to dissipate heat for the circular saw blade.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The center half gear ring, the first half gear ring and the second half gear ring are arranged into a structure that can be folded and unfolded, which is convenient for loading the shaft rod. Compared with the end face limitation of the traditional chuck and the length limitation of the machine, the present invention is not only suitable for clamping short raw material shaft rods, but also more suitable for clamping and positioning long raw material shaft rods. Multiple cutting and blanking can be performed in one clamping and positioning, which improves the efficiency of sawing and blanking.

[0016] 2. The wide-body gear drives the half gear ring to rotate, and the clamped shaft also rotates. The shaft rotates during the cutting process. During the sawing process, the circular saw blade evenly cuts from the outside of the shaft to the axis center, reducing the cutting stress and effectively weakening the deformation of the shaft and the wear of the circular saw blade.

[0017] 3. Pass high voltage electricity through the positive discharge needle and the negative patch, forming a strong electric field between the two. The ionized air at the positive discharge needle moves toward the negative patch at high speed. At the same time, the simple friction and collision of air molecules drive the gas flow around the ionized air, forming ion wind to dissipate heat for the circular saw blade.

The operator uses the overhead lifting device to move the shaft rod to be sawed above the machine 1, so that the shaft rod falls between the fixed clamping module 10 and the mobile clamping module 11.

[0030] The interior of the center half gear ring 13 is provided with a nut sleeve 16, a worm wheel 17, a worm 18 and a first servo motor 19. The nut sleeve 16 is rotatably mounted inside the center half gear ring 13. The worm wheel 17 is integrally arranged on the outside of the nut sleeve 16. The worm 18 is mounted on the motor shaft of the first servo motor 19. The worm wheel 17 and the worm 18 are meshed for transmission. A screw 20 and a clamping block 21 are provided on the inner ring of the center half gear ring 13. The screw 20 passes through the interior of the center half gear ring 13. Several axially-opened slots are provided on the screw 20. The screw 20 is slidably connected to the center half gear ring 13. The screw 20 is threadedly connected to the nut sleeve 16. The clamping block 21 It is installed at the end of the screw 20 away from the nut sleeve 16. In the initial state, the center half gear ring 13, the first half gear ring 14 and the second half gear ring 15 are all received in the assembly block 12. The servo drive module makes the first half gear ring 14 and the second half gear ring 15 slide along the dovetail slider 22 on both sides of the center half gear ring 13. After the first half gear ring 14 and the second half gear ring 15 are unfolded, the tooth profiles of the center half gear ring 13, the first half gear ring 14 and the second half gear ring 15 form a complete outer-inner gear ring on the axial projection surface. The three half gear rings have successive profile transitions, and the wide-body gear 24 can continuously drive the three half gear rings to rotate as a whole in the assembly block 12.

[0031] The structural settings on the first half gear ring 14 and the second half gear ring 15 are the same as the structural settings on the center half gear ring 13. An arc-shaped dovetail slider 22 is provided on both sides of the center half gear ring 13. The curvature of the two dovetail sliders 22 is the same as the curvature of the center half gear ring 13. The first half gear ring 14 and the second half gear ring 15 are provided with a dovetail groove 23 that matches the dovetail slider 22 on the side close to the center half gear ring 13. The first half gear ring 14 and the second half gear ring 15 are slidingly connected to the dovetail slider 22 on the center half gear ring 13 through the dovetail groove 23. A servo drive module is provided at the connection between the first half gear ring 14 and the second half gear ring 15 and the center half gear ring 13. A slide groove is opened on the top of the machine 1. The movable clamping module 11 is installed in the slide groove through the servo drive module. The structural setting method of the movable clamping module 11 is the same as the structural setting method of the fixed clamping module 10.

[0032] At the same time as the first half gear ring 14 and the second half gear ring 15 are unfolded, the three clamping blocks 21 are dispersed to positions spaced 120 degrees apart. The first servo motors 19 in all the half gear rings are energized to drive the worm 18 to rotate, the worm 18 drives the worm wheel 17 to rotate, and the worm wheel 17 drives the nut sleeve 16 to rotate at the same time. Since the screw 20 can only slide and cannot rotate, the screw 20 is extended outward under the drive of the nut sleeve 16, so that all the clamping blocks 21 are against the shaft rod, and the shaft rod is clamped by the three clamping blocks 21 at positions spaced 120 degrees apart, which plays a role in quickly positioning the shaft rod. The open fixed clamping module 10 and the movable The dynamic clamping module 11 clamps the shaft rod to facilitate the loading of the shaft rod. After the fixed clamping module 10 and the mobile clamping module 11 clamp the shaft rod raw material, the electric chuck clamps the blanking end of the shaft rod. After cutting and blanking, the clamping block 21 in the fixed clamping module 10 releases the shaft rod, and the mobile clamping module 11 drives the shaft rod to move, pushing the shaft rod out to a certain length for subsequent cutting. Compared with the end face limitation of the traditional chuck and the length limitation of the machine 1, the present invention is not only suitable for the clamping of short raw material shaft rods, but also more suitable for the clamping and positioning of long raw material shaft rods. Multiple cutting and blanking can be performed in one clamping and positioning, which improves the efficiency of sawing and blanking.

[0033] A pair of swing arms 27 are rotatably installed inside the machine 1, and a transmission shaft 26 is rotatably installed at the other end of the pair of swing arms 27. A motor bracket is provided on the swing arm 27 away from the fixed clamping module 10, and a second servo motor 25 is installed on the motor bracket. The transmission shaft 26 is connected to the motor shaft of the second servo motor 25. An electromagnet 28 is provided inside the machine 1, and the electromagnet 28 is energized to adsorb the swing arm 27. Two wide-body gears 24 are provided on the transmission shaft 26, one wide-body gear 24 is fixedly mounted on the transmission shaft 26, and the other wide-body gear 24 is slidably mounted on the transmission shaft 26. The fixedly mounted wide-body gear 24 is meshed with the center half-tooth ring 13 in the fixed clamping module 10, and two baffles are also installed at the bottom of the assembly block 12 in the mobile clamping module 11. The slidably mounted wide-body gear 24 is restricted between the two baffles, and the slidably mounted wide-body gear 24 is meshed with the center half-tooth ring 13 in the mobile clamping module 11.

[0034] When the mobile clamping module 11 is displaced, the wide-body gear 24 is driven to slide on the transmission shaft 26 through the baffle. Even if the position of the mobile clamping module 11 changes, the wide-body gear 24 can still drive the half-tooth ring in the mobile clamping module 11 to rotate. During the sawing process, if the shaft is fixed, as the sawing depth increases, the stress of the circular saw blade 4 is the largest when it cuts to the width of the shaft diameter, and gradually decreases after crossing the width of the shaft diameter. The uneven sawing stress causes the tool shaft to deform and the circular saw blade 4 to wear. Using an electromagnet 28 is energized to adsorb the two swing arms 27, and the swing arms 27 drive the transmission shaft 26 to move upward, so that the two wide-body gears 24 engage with the half-toothed ring. The second servo motor 25 drives the transmission shaft 26 to rotate, and the transmission shaft 26 drives the two wide-body gears 24 to rotate, and the wide-body gears 24 drive the half-toothed ring to rotate, and the clamped shaft also rotates. The shaft body rotates during the cutting process, and the circular saw blade 4 cuts evenly from the outside of the shaft to the axis during the sawing process, reducing the cutting stress and effectively weakening the deformation of the shaft and the wear of the circular saw blade 4.

[0035] The cutting machine includes a gearbox 3, which is slidably mounted on a lifting vertical plate 2. A main motor 6 is provided on the top of the gearbox 3. Pulleys are provided on the motor shaft of the main motor 6 and the input end of the gearbox 3. A V-belt 7 is connected between the two pulleys. A circular saw blade 4 is installed on the output end of the gearbox 3. A protective cover 5 that half wraps the circular saw blade 4 is also provided on the gearbox 3. A positive discharge needle 8 and a negative patch 9 are provided inside the protective cover 5. The positive discharge needle 8 and the negative patch 9 are both connected to the control system through a circuit. After high voltage electricity is passed through the positive discharge needle 8 and the negative patch 9, a strong electric field is formed between the two. The ionized air at the positive discharge needle 8 moves toward the negative patch 9 at a high speed. At the same time, the simple friction and collision of air molecules drive the gas around the ionized air to flow, forming an ion wind to dissipate heat from the circular saw blade 4.

[0036] The working principle of the present invention is as follows: before cutting the shaft, the control system controls the movement of the servo drive module and adjusts the position of the mobile clamping module 11 on the machine 1 according to the length of the shaft. The operator uses the overhead lifting device to move the shaft to be sawed above the machine 1 so that the shaft falls between the fixed clamping module 10 and the mobile clamping module 11. In the initial state, the center half gear ring 13, the first half gear ring 14 and the second half gear ring 15 are all received in the assembly block 12. The servo drive module causes the first half gear ring 14 and the second half gear ring 15 to slide along the dovetail slider 22 on both sides of the center half gear ring 13. After the first half gear ring 14 and the second half gear ring 15 are unfolded, the tooth profiles of the center half gear ring 13, the first half gear ring 14 and the second half gear ring 15 form a complete outer and inner gear ring on the axial projection surface. The three half gear rings have successive profile transitions, and the wide-body gear 24 can continuously drive the three half gear rings to rotate as a whole in the assembly block 12.

[0037] At the same time as the first half gear ring 14 and the second half gear ring 15 are unfolded, the three clamping blocks 21 are dispersed to positions spaced 120 degrees apart. The first servo motors 19 in all the half gear rings are energized to drive the worm 18 to rotate, the worm 18 drives the worm wheel 17 to rotate, and the worm wheel 17 drives the nut sleeve 16 to rotate at the same time. Since the screw 20 can only slide and cannot rotate, the screw 20 is extended outward under the drive of the nut sleeve 16, so that all the clamping blocks 21 are against the shaft rod, and the shaft rod is clamped by the three clamping blocks 21 at positions spaced 120 degrees apart, which plays a role in quickly positioning the shaft rod. The open fixed clamping module 10 and the movable The dynamic clamping module 11 clamps the shaft rod to facilitate the loading of the shaft rod. After the fixed clamping module 10 and the mobile clamping module 11 clamp the shaft rod raw material, the electric chuck clamps the blanking end of the shaft rod. After cutting and blanking, the clamping block 21 in the fixed clamping module 10 releases the shaft rod, and the mobile clamping module 11 drives the shaft rod to move, pushing the shaft rod out to a certain length for subsequent cutting. Compared with the end face limitation of the traditional chuck and the length limitation of the machine 1, the present invention is not only suitable for the clamping of short raw material shaft rods, but also more suitable for the clamping and positioning of long raw material shaft rods. Multiple cutting and blanking can be performed in one clamping and positioning, which improves the efficiency of sawing and blanking.

[0038] When the mobile clamping module 11 is displaced, the wide-body gear 24 is driven to slide on the transmission shaft 26 through the baffle. Even if the position of the mobile clamping module 11 changes, the wide-body gear 24 can still drive the half-tooth ring in the mobile clamping module 11 to rotate. During the sawing process, if the shaft is fixed, as the sawing depth increases, the stress of the circular saw blade 4 is the largest when it cuts to the width of the shaft diameter, and gradually decreases after crossing the width of the shaft diameter. The uneven sawing stress causes the tool shaft to deform and the circular saw blade 4 to wear. Using an electromagnet 28 is energized to adsorb the two swing arms 27, and the swing arms 27 drive the transmission shaft 26 to move upward, so that the two wide-body gears 24 engage with the half-toothed ring. The second servo motor 25 drives the transmission shaft 26 to rotate, and the transmission shaft 26 drives the two wide-body gears 24 to rotate, and the wide-body gears 24 drive the half-toothed ring to rotate, and the clamped shaft also rotates. The shaft body rotates during the cutting process, and the circular saw blade 4 cuts evenly from the outside of the shaft to the axis during the sawing process, reducing the cutting stress and effectively weakening the deformation of the shaft and the wear of the circular saw blade 4.

[0039] After high voltage electricity is passed through the positive discharge needle 8 and the negative patch 9, a strong electric field is formed between the two. The ionized air at the positive discharge needle 8 moves toward the negative patch 9 at a high speed. At the same time, the simple friction and collision of air molecules drive the gas flow around the ionized air, forming an ion wind to dissipate heat for the circular saw blade 4.
