Description

Technical Field

[0001] This invention relates to the field of belt pulley processing technology, and in particular to a milling device and method for a generator unidirectional belt pulley. Background Technology

[0002] One-way pulleys are an important component of generator systems, mainly used to transmit power and control the generator's working direction. Traditional machining methods often cannot meet the precision requirements of modern industry for parts, so it is necessary to develop specialized turning equipment to improve machining quality and efficiency.

[0003] Upon investigation, it was found that existing turning equipment often uses a uniform three-jaw centering clamping mechanism to hold the workpiece. This method can only provide a tight clamping within a certain diameter range, and it is prone to misalignment and vibration when the rotation speed is too high. Moreover, under the action of the push rod at the other end, this clamping mechanism also needs to bear radial pressure, which increases the instability of the clamping. In order to address the various hidden dangers brought about by this clamping mechanism, we propose a new type of generator unidirectional belt pulley milling equipment and method. Summary of the Invention

[0004] To overcome the aforementioned shortcomings of the prior art, the present invention aims to provide a milling device applicable to pulleys with a wide range of diameters and inner diameters:

[0005] This invention provides a generator unidirectional pulley milling device, comprising a box-shaped worktable with an opening facing downwards. A chip removal groove is pre-reserved at the edge of the front face of the upper surface of the worktable. An electric slider is slidably connected to the middle of the rear side of the worktable. A tool holder module extending towards the turning position is provided at the top of the electric slider. An axial feed bearing is slidably connected to one end of the upper surface of the worktable, and a push rod is rotatably connected to the middle of the axial feed bearing. A main bearing seat is fixed to the other end of the upper surface of the worktable, and a chuck mechanism is rotatably connected to the main bearing seat. The chuck mechanism includes a main rotating cylinder with a horizontally placed tubular structure. A flared plate is reserved at one end of the rotating drum near the chip removal groove, and a flanged tube with the same axis is fixed to the inner wall of the main rotating drum near the flared plate. A hexagonal fixing frame is fixed to the end of the flanged tube near the chip removal groove, and three clamping arms distributed centrally symmetrically are rotatably connected to the outer wall of the hexagonal fixing frame. A locking worm gear is rotatably sleeved on the outer wall of the straight section of the flanged tube near the inside of the flared plate, and three arc-shaped sliding holes are opened on the surface of the locking worm gear near the circumferential edge. The end of the clamping arm away from the workpiece body is slidably inserted into the corresponding arc-shaped sliding hole. A manually adjustable worm is provided on the outer wall of the flared plate, which is obliquely inserted and meshes with the locking worm gear.

[0006] A further feature of this invention is that a flywheel is fixedly fitted onto the outer circumference of the main drum away from the axial propulsion bearing, and a belt groove is formed on the outer circumference of the flywheel. A main motor is fixed to the inner wall of the worktable near the flywheel, and a drive pulley is fixed to the end of the output shaft of the main motor extending out of the worktable. A conveyor belt is wound between the drive pulley and the outer circumference of the flywheel. A fixing groove for fixing the main bearing seat is formed on the upper surface of the worktable near the end of the main bearing seat. Symmetrical anti-slip bearings are respectively embedded in the inner wall of the main bearing seat near both ends to drive the rotation of the entire clamping mechanism.

[0007] A further feature of this invention is that an inner fixing ring is pre-installed on the inner circumferential wall of the main rotating drum near the end of the flanged tube, and the end of the flanged tube is fixed to the surface of the inner fixing ring by bolts; sliding bearings are embedded near both ends of the inner circumferential wall of the flanged tube, and the two sliding bearings are slidably connected by the same push rod; an external threaded sleeve is screwed to the end of the inner circumferential wall of the main rotating drum away from the flared plate, and multiple nut clips are fixed to the inner circumferential wall of the external threaded sleeve in a centrally symmetrical distribution. The nut clips are connected by a set of opposing nuts, and an adjusting stud is screwed into the middle of the opposing nuts. A compression spring is fixed between the adjusting stud and the push rod. A top cone block two with an integral frustum structure is fixed to one end of the push rod near the hexagonal fixing frame. A top cone block one coaxial with the top cone block two is fixed to one end of the push rod one near the clamping mechanism. The diameter of the end of the top cone block one and the top cone block two that are close to each other is smaller than the diameter of their other ends. An anti-disengagement bearing is provided between the inner circumference of the locking worm gear disc and the outer wall of the flanged tube.

[0008] A further feature of this invention is that the outer wall of the hexagonal fixing frame has three centrally symmetrically distributed hinged notches, and the clamping arm is rotatably connected to the corresponding hinged notches. When the clamping arm rotates, the surface it sweeps passes through the turning axis. The center positions of the two ends of the arc-shaped sliding hole are at different distances from the center of the locking worm gear, ensuring that when the locking worm gear rotates, it drives the clamping arm to rotate around the hinged notches.

[0009] A further feature of this invention is that the upper and lower surfaces of the clamping arm away from the locking worm gear are provided with cylindrical rotating grooves, and the center lines of the two cylindrical rotating grooves are parallel to each other. The center lines of the cylindrical rotating grooves are perpendicular to the center line of the main rotating cylinder. A shaft is rotatably connected in each cylindrical rotating groove. The outer circumferential walls of the two shafts are respectively fixed with hinged top blocks one and two with opposite arc surfaces. These are used to contact the surface of the workpiece body when clamping the inner or outer wall of the workpiece body and to play a role in preventing slippage and collision.

[0010] A further feature of the present invention is that a conical mask is fixedly sleeved on the outer circumference of the hexagonal fixing frame, and the flared edge of the conical mask is fixed to the opening of the flared plate by bolts; by setting the conical mask, the probability of chips flying into the flared plate during milling can be reduced, thereby effectively preventing the meshing of the manually adjusting worm gear and the locking worm wheel from being blocked.

[0011] A further feature of this invention is that the worktable has two parallel anti-slip grooves perpendicular to the chip removal groove at one end near the axial propulsion bearing, and a cylindrical boss slider is slidably connected in each anti-slip groove. The top ends of the two cylindrical boss sliders are fixed to the lower surface of the axial propulsion bearing. Two symmetrical tapered roller bearings are provided between the inner wall of the axial propulsion bearing and the outer wall of the push rod. A propulsion rack extending away from the chip removal groove is fixed in the middle of the lower surface of the axial propulsion bearing. An upwardly extending motor frame is fixed at one end of the worktable near the axial propulsion bearing, and a servo motor is fixed at the top of the motor frame. Symmetrical gear support frames are fixed on the front and rear sides of the two anti-slip grooves on the upper surface of the worktable, and the top ends of the two gear support frames are rotatably connected to the same worm gear disk. The outer circumference of the worm gear disk near the bottom end meshes with the upward-facing propulsion rack, and a worm sleeve meshing with the worm gear disk is fixed at the top of the output shaft of the servo motor.

[0012] A further feature of the present invention is that multiple rollers are provided between the lower surface of the propulsion rack and the upper surface of the worktable, which can ensure that the propulsion rack remains engaged with the worm gear disk when moving forward and backward, and ensure that the propulsion rack does not disengage when subjected to axial compressive force.

[0013] A further feature of this invention is that the tool holder module includes a windmill block slidably inserted into the top of the electric slider and extending towards the center line of the main rotary drum. The upper surface of the windmill block has outwardly extending protrusions near its four corners. The upper surface of each of the extending protrusions has an anti-slip groove, and an L-shaped clamping block is hinged to the upper surface of the windmill block near the anti-slip groove. The bottom of the anti-slip groove and the L-shaped clamping block both have coaxial threaded holes, and a cutting tool is placed in the anti-slip groove. This design prevents the L-shaped clamping block from falling off during tool installation and replacement, and also makes clamping adjustments very convenient when needed.

[0014] A method for milling a unidirectional pulley for a generator includes the following steps:

[0015] S1: Before use, select the appropriate cutting tool according to the required groove depth and width. Then control the servo motor to rotate in the reverse direction to drive the axial propulsion bearing and push rod one to retract as a whole to leave space for fixing the workpiece body's original blank. After it is enough to put the workpiece body between the top cone block one and the top cone block two, start the servo motor in the forward direction until the workpiece body is fixed.

[0016] S2: Control the operation of the clamping mechanism to clamp the outer circumference of the workpiece body. At this time, simply turn the flaring disc of the main rotating drum, turn the handwheel of the manual adjusting worm gear to the front, and then slowly turn the handwheel to drive the locking worm gear disc to rotate. At this time, the three clamping arms close to the workpiece body will slowly converge towards the middle until the workpiece body is clamped. If the diameter of the workpiece body is large, the top cone block two can be removed first, and then the end of the workpiece body can be sleeved on the outer wall of the three clamping arms. Then, control the clamping arms to expand outward to fix the workpiece body.

[0017] S3: After the workpiece body is clamped and fixed, start the main motor to drive the workpiece body to rotate as a whole. Then, control the cutting tool in the tool holder module to slowly approach the outer circumference of the workpiece body and perform milling according to the program path.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. With three synchronously rotating clamping arms, it can not only clamp small-diameter workpieces from the outer wall, but also fix large-diameter workpieces from the inside out. When fixing, simply turn the worm gear manually from the outer wall of the main rotating drum. The adjustment is convenient and the self-locking effect is good.

[0020] 2. By setting up top cone block one and top cone block two with a frustum-shaped structure, the workpiece body can be axially fixed before clamping, ensuring that the workpiece body is not eccentric when clamped from the side later, which also plays an auxiliary role in preventing it from falling off.

[0021] 3. By setting the worm sleeve and worm wheel to mesh, not only can the push rod one be pushed to press against the workpiece body with less effort, but the adjustable range of each push distance is also smaller. In addition, it has a power failure self-locking function to prevent the workpiece body from falling when the power is off. Attached Figure Description

[0034] The technical solutions 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.

[0035] In this invention, reference is made to Figures 1-11 This solution specifically provides a generator unidirectional pulley milling device, including a box-shaped worktable 1 with an opening facing downwards. A chip removal groove 101 is pre-reserved at the edge of the front face on the upper surface of the worktable 1.

A hexagonal fixing frame 21 is fixed to one end of the flange tube 25 near the chip removal groove 101. Three clamping arms 2 are rotatably connected to the outer wall of the hexagonal fixing frame 21 in a centrally symmetrical distribution. A locking worm gear 22 is rotatably sleeved on the outer wall of the straight pipe with flange tube 25 near the inside of the flared plate. Three arc-shaped sliding holes are opened on the disc surface of the locking worm gear 22 near the circumferential edge. The end of the clamping arm 2 away from the workpiece body 20 is slidably inserted into the corresponding arc-shaped sliding hole. A manually adjustable worm 16 is provided on the circumferential outer wall of the flared plate, which is obliquely inserted and meshes with the locking worm gear 22. With the three synchronously rotating clamping arms 2, not only can small-diameter workpiece bodies 20 be clamped from the outer wall, but large-diameter workpiece bodies 20 can also be fixed from the inside out. When fixing, it is only necessary to manually adjust the worm 16 by turning it from the outer wall of the main rotating drum. The adjustment is convenient and the self-locking effect is good.

[0036] A flywheel disk 15 is fixedly fitted onto the outer circumference of the main drum away from the axial propulsion bearing 3, and a belt groove is provided on the outer circumference of the flywheel disk 15. A main motor 23 is fixed to the inner wall of the worktable 1 near the flywheel disk 15, and a drive pulley 17 is fixed to the end of the output shaft of the main motor 23 extending out of the worktable 1. A conveyor belt is wound between the drive pulley 17 and the outer circumference of the flywheel disk 15. A fixing groove 103 for fixing the main bearing seat 14 is provided on the upper surface of the worktable 1 near the end of the main bearing seat 14. Symmetrical anti-slip bearings 1401 are respectively embedded in the inner wall of the main bearing seat 14 near both ends to drive the rotation of the entire clamping mechanism 13.

[0037] Reference Figures 4-10 An inner fixing ring 131 is reserved on the inner circumference of the main rotating drum near the end of the flanged tube 25, and the end of the flanged tube 25 is fixed to the surface of the inner fixing ring 131 by bolts; sliding bearings 27 are embedded on both ends of the inner circumference of the flanged tube 25, and the same push rod 24 is slidably connected between the two sliding bearings 27; an external threaded tube sleeve 18 is screwed to the end of the inner circumference of the main rotating drum away from the flared plate, and multiple nut clips 183 are fixed on the inner circumference of the external threaded tube sleeve 18 in a centrally symmetrical distribution, and the same set of opposing nuts 181 are clamped between the multiple nut clips 183, and an adjusting stud 182 is screwed to the middle of the opposing nuts 181, and the adjusting stud 182 is connected to the push rod 24. A compression spring is fixed; a top cone block 241 with an integral frustum structure is fixed at one end of the top rod 24 near the hexagonal fixing frame 21, and a top cone block 19 coaxial with the top cone block 241 is fixed at one end of the push rod 18 near the clamping mechanism 13; the diameter of the end of the top cone block 19 and the top cone block 241 that are close to each other is smaller than the diameter of their other ends; an anti-detachment bearing 26 is provided between the inner circumference of the locking worm gear disk 22 and the outer wall of the flanged tube 25; by setting the top cone block 19 and the top cone block 241 with frustum structure, the workpiece body 20 can be axially fixed before clamping, ensuring that the workpiece body 20 is not eccentric when clamped from the side later, which also plays an auxiliary role in preventing detachment.

[0038] Reference Figures 4-6 The outer wall of the hexagonal fixing frame 21 has three centrally symmetrically distributed hinge notches 28, and the clamping arm 2 is rotatably connected in the corresponding hinge notch 28. When the clamping arm 2 rotates, the surface swept by it passes through the turning axis. The center positions of the two ends of the arc-shaped sliding hole are at different distances from the center of the locking worm gear 22, ensuring that when the locking worm gear 22 rotates, it drives the clamping arm 2 to rotate around the hinge notch 28.

[0039] Reference Figure 8 , Figure 9 and Figure 11 The clamping arm 2 has cylindrical rotating grooves on both the upper and lower surfaces at the end away from the locking worm gear 22. The axis lines of the two cylindrical rotating grooves are parallel to each other, and the axis lines of the cylindrical rotating grooves are perpendicular to the axis lines of the main rotating drum. The cylindrical rotating grooves are rotatably connected to the shafts. The outer circumference of the two shafts is respectively fixed with hinged top blocks 1 201 and 201 with opposite arc surfaces. These are used to contact the surface of the workpiece body 20 when clamping the inner or outer wall of the workpiece body 20 and to play a role in preventing slippage and collision.

[0040] Reference Figure 8A conical mask 12 is fixedly sleeved on the outer circumference of the hexagonal fixing frame 21, and the flared edge of the conical mask 12 is fixed to the opening of the flared plate by bolts. The conical mask 12 can reduce the probability of chips flying into the flared plate during milling, thereby effectively preventing the meshing of the manual adjusting worm gear 16 and the locking worm wheel 22 from being blocked.

[0041] Reference Figure 3 and Figure 6 Two parallel and perpendicular anti-slip grooves 102 are provided at the end of the worktable 1 near the axial propulsion bearing 3, and both are slidably connected to the chip removal groove 101. The tops of the two anti-slip grooves 102 are fixed to the lower surface of the axial propulsion bearing 3. Two symmetrical tapered roller bearings are provided between the inner wall of the axial propulsion bearing 3 and the outer wall of the push rod 8. A propulsion rack 4 extending away from the chip removal groove 101 is fixed in the middle of the lower surface of the axial propulsion bearing 3. An upwardly extending motor frame 601 is fixed at the end of the worktable 1 near the axial propulsion bearing 3, and a servo motor is fixed at the top of the motor frame 601. The upper surface of the servo motor 6 and the worktable 1 is fixed with symmetrical gear support frames 5 on the front and rear sides of the two anti-slip grooves 102. The top of the two gear support frames 5 are rotatably connected to the same worm gear disk 7. The outer circumference of the worm gear disk 7 near the bottom end meshes with the toothed rack 4 with its tooth surface facing upward. The top of the output shaft of the servo motor 6 is fixed with a worm sleeve that meshes with the worm gear disk 7. By setting the worm sleeve to mesh with the worm gear disk 7, not only can the push rod 8 be pushed to press against the workpiece body 20 with less effort, but the adjustable range of each push distance is also smaller. In addition, it has a power failure self-locking function to prevent the workpiece body 20 from falling when the power is off.

[0042] Reference Figure 4 Multiple rollers are provided between the lower surface of the push rack 4 and the upper surface of the worktable 1 to ensure that the push rack 4 remains engaged with the worm gear 7 when moving forward and backward, and to ensure that the push rack 4 does not disengage when subjected to axial compressive force.

[0043] Reference Figure 1 and Figure 7The tool holder module 11 includes a windmill block that is slidably inserted into the top of the electric slider 9 and extends towards the center line of the main rotating drum. The upper surface of the windmill block has outwardly extending protrusions near the four corners. The upper surface of the extending protrusions is provided with anti-slip grooves 1101. The upper surface of the windmill block is hinged with L-shaped clamping blocks 1102 near the anti-slip grooves 1101. The bottom of the anti-slip grooves 1101 and the L-shaped clamping blocks 1102 are provided with coaxial screw holes. A cutting tool 1103 is provided in the anti-slip grooves 1101. With this design, the L-shaped clamping blocks 1102 can be prevented from falling off when installing and replacing the cutting tool 1103, and the adjustment is also very convenient when clamping is required.

[0044] A method for milling a unidirectional pulley for a generator includes the following steps:

[0045] S1: Before use, select the appropriate cutting tool 1103 according to the required groove depth and width. Then, control the servo motor 6 to rotate in the reverse direction to drive the axial propulsion bearing 3 and push rod 8 to retract as a whole to leave space for fixing the workpiece body 20. After the workpiece body 20 is placed between the top cone block 19 and the top cone block 241, start the servo motor 6 in the forward direction until the workpiece body 20 is fixed.

[0046] S2: Control the operation of the clamping mechanism 13 to clamp the outer circumference of the workpiece body 20. At this time, simply turn the flaring disc of the main rotating drum, turn the handwheel of the manual adjusting worm gear 16 to the front, and then slowly turn the handwheel to drive the locking worm gear disc 22 to rotate. At this time, the three clamping arms 2 close to the workpiece body 20 will slowly converge towards the middle until the workpiece body 20 is clamped. If the diameter of the workpiece body 20 is large, the top cone block 241 can be removed first, and then the end of the workpiece body 20 can be sleeved on the outer wall of the three clamping arms 2. Then, control the clamping arms 2 to expand outward to fix the workpiece body 20.

[0047] S3: After the workpiece body 20 is clamped and fixed, start the main motor 23 to drive the workpiece body 20 to rotate as a whole. Then, control the cutting tool 1103 in the tool holder module 11 to slowly approach the outer circumference of the workpiece body 20 and perform milling according to the program path.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
