[0002] A gear cutting machine is a mechanical device used for processing gears. Its working principle mainly includes gear processing methods, main components, and working process. The working principle of a gear cutting machine is based on the reduction and shaping of gear tooth surfaces. Its processing methods mainly include hobbing, hobbing grinding, and hobbing quenching. Among them, hobbing is achieved by using a gear processing tool to make the tool contact the gear surface. By rotating the gear and the tool, the tooth profile on the tool and the gear tooth profile interfere with each other, thereby realizing gear processing. However, there is currently no gear cutting equipment on the market that can perform steering gear cutting, especially for gear cutting in gearboxes.

[0003] Most existing gear grinding machines can only grind teeth on conventional gears or on gear strands of a single shape or type.

This allows the tail end of the head rod to be locked by the double-sided tongue while simultaneously sliding past the end of the double-sided tongue lock and disengaging from the cavity.

[0017] This invention provides a tooth-pressing machine, which has the following beneficial effects:

[0018] 1. This gear-making machine, under the control of the translational movement of the drive rail, moves the straight rail away from the guide sleeve, and finally allows the first clamp to be reinserted into the bottom of the second clamp. By activating the vibrator, the second clamp and the first clamp are driven to impact and collide vertically. The elastic extension and contraction of the straight rod at the bottom of the bottom sleeve can be used to counter-impact the bottom of the bottom sleeve, thereby transmitting the impact force to the precision clamping assembly of the large ball joint. This can shake off the debris attached to the precision clamping assembly, the tooth strand, and the large ball joint onto the machine tool, realizing the automatic shaking off and cleaning of debris on the surface of the composite clamping assembly, avoiding the accumulation of debris on the composite clamping assembly and affecting the subsequent precision machining of irregularly shaped gears.

[0019] Second, this gear-cutting machine utilizes a rubber ring installed on the surface of the rib ring to bounce away debris that falls onto the rib ring, reducing the impact damage to the rib ring surface when debris falls off. This also allows the debris to accumulate away from the periphery of the large ball joint. At the same time, the design of the first and second sealing rings ensures that even if the outermost first sealing ring is damaged or flipped outward, the second sealing ring can continue to intercept and guide the debris, providing double protection to prevent debris from falling and clogging the gap between the large ball joint and the machine tool.

[0020] Third, this tooth-cutting machine, through the rotation of the electric gripper driving the rotating disk, can automatically adjust the orientation of the toothed material towards the tooth-cutting head, and can automatically control the initial tooth-cutting position of the tooth-cutting head on the toothed material. At the same time, it can also perform return tooth-cutting on local teeth, realizing secondary fine tooth-cutting processing on the already-cut parts. It can not only remove some of the debris blocking the gaps between the teeth, but also perform secondary re-cutting on the formed teeth, further improving the tooth-cutting accuracy.

[0021] Fourth, this tooth-making machine uses corner claws to limit the positioning ring in three directions around its perimeter. Combined with the insertion of the cone block between the sector block and the central ring, it achieves overall positioning and assembly of the positioning ring by the base. This provides a stable clamping and positioning platform for the bottom of the base block. Subsequently, combined with the electric gripper, it automatically clamps and limits the base block placed on top of the positioning ring around its perimeter. This allows the base block to provide a precise positioning structure for the threaded positioning of the toothed material on the rotary table, preventing the toothed material from shifting or shaking on the rotary table.

[0022] Fifth, this tooth-cutting machine achieves convenient and high-precision positioning and installation of the toothed material on the rotating disk by inserting the toothed material onto the tensioning rod, and then connecting it to the tensioning rod by inserting a bolt sleeve into the middle of the top of the toothed material. This ensures that the toothed material can always remain in a stable state for the tooth-cutting head to perform tooth-cutting processing, further guaranteeing the fineness of the toothed material being toothed. Moreover, under this high-precision positioning and clamping installation guarantee structure, the tooth-cutting head can also perform tooth-cutting processing on toothed materials with different wall thicknesses.

[0023] VI. This tooth-cutting machine, by activating the second blade cylinder to extend the push rod, slides the sliding wall teeth at the tail end of the head rod through the protrusion at the end of the double-sided tongue lock and pushes them out from the opening of the sleeve fitting. This causes the head rod to rotate counterclockwise around the axis of the positioning rod, while one end of the tooth-cutting head shifts away from the toothed material. This means that the entire tooth-cutting head is no longer completely tangent to the surface of the toothed material, but rather the part of the tooth-cutting head near the head rod contacts the toothed material. Furthermore, this results in varying depths of tooth cutting between the tooth cutter on the toothed head and the surface of the toothed material. This avoids the tangential tooth cutting of the toothed material in conventional operations and enables tooth cutting to different depths. It also allows for flexible switching of the tooth-cutting operation part of the tooth-cutting head and local adjustment of the offset position of the tooth-cutting head on the feeder to cooperate with the composite clamping assembly for tooth cutting of different shapes and sizes of toothed materials.

[0024] 7. This tooth-crushing machine uses the sliding engagement of the double-sided tongue lock and the sliding wall teeth to assist the push rod in returning the entire sleeve to the central axis of the opening, ensuring that the tooth-crushing head can perform normal tooth-crushing processing on the toothed material under the rotation drive of the feeder.

[0025] 8. This tooth-crushing machine uses a double-headed spring tongue that moves within each locking hole under the guidance of the guide tongue groove. By using the double-headed spring tongue to move and insert within the locking hole, the head rod is positioned and locked on the U-shaped body, ensuring that the position of the tooth-crushing head will not shift during tooth-crushing and ensuring the tooth-crushing accuracy of irregularly shaped toothed parts.

[0026] 9. This gear-cutting machine automatically adjusts the position of the straight rail on the turntable by driving the rail body. Through the connection between the telescopic rod and the bottom of the base sleeve, the angle between the axis of the large ball joint and the plane at the top of the machine tool changes. This allows the gear material to rotate eccentrically when the turntable rotates, adaptively changing the gear-cutting position of the feed machine. The gear-cutting head can then be used to cut gears at different heights on the surface of the gear material, processing it into various special-shaped gear parts. This enables the gear-cutting machine to process gear parts of different models and shapes, meeting the special needs of different structural components. It solves the problem of traditional gear-cutting machines only being able to process conventional gear parts, achieving multi-purpose functionality and enhancing the overall practicality of the gear-cutting machine.

Detailed Implementation

[0043] 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.

[0044] First embodiment, such as Figures 1 to 15 As shown, the present invention provides a technical solution: a gear punching machine, including a machine tool 1, a feed machine 2 installed on the right side of the top of the machine tool 1, a spinning machine 4 threadedly installed on the rear side of the middle of the top of the machine tool 1, and a tailstock tip 5 installed on the left side of the top of the machine tool 1.

[0045] It also includes a composite clamping assembly 3, which is installed at the top center of the machine tool 1. The composite clamping assembly 3 includes a large ball joint 31 rotatably connected to the middle of the machine tool 1. A bottom sleeve 32 is installed on the outer surface of the large ball joint 31 near the bottom. A telescopic rod 33 is installed at the bottom of the bottom sleeve 32. An eaves ring 34 is fitted around the large ball joint 31. The bottom of the eaves ring 34 is fitted into the top center of the machine tool 1. A precision clamping assembly 35 is installed on the outer surface of the large ball joint 31 near the top. The precision clamping assembly 35 and the bottom sleeve 32 are arranged symmetrically about the large ball joint 31.

[0046] A turntable 36 is installed at the end of the telescopic rod 33 away from the large ball joint 31. The bottom of the turntable 36 is fitted onto the support leg at the bottom of the machine tool 1. Two sets of drive rails 37 are installed at the top of the turntable 36. A guide sleeve 38 is also installed at the top of the turntable 36. The guide sleeve 38 is installed on the side away from the drive rails 37. The drive rails 37 and the guide sleeve 38 are installed together on the axis passing through the center of the circle. A straight rail 39 is installed on the drive rail 37. The straight rail 39 is slidably installed through the drive rail 37. A vertical rod head 30 is threaded onto the end of the straight rail 39 away from the guide sleeve 38.

[0047] The tool assembly 6 is mounted on the feed machine 2. The tool assembly 6 includes a sleeve 61 mounted on the feed machine 2. A corner seat 62 is fixedly connected to the end of the sleeve 61 away from the feed machine 2. A U-shaped part 63 is installed at the end of the corner seat 62 away from the sleeve 61. A first blade cylinder 64 is threaded on one side of the U-shaped part 63. A tooth-cutting cutter 65 is assembled in the middle of the sleeve 61. A clamp 66 is installed in the middle of the inner side of the corner seat 62. Two sets of positioning rods 67 are threaded on the surface of the clamp 66. The clamp 66 is rotatably mounted to the corner seat 62 through the positioning rods 67. The tooth-cutting cutter 65 is rotatably mounted to the feed machine 2 through the sleeve 61.

[0048] In use, the drive rail 37 is first activated to drive the straight rail 39 to move the guide sleeve 38 in a translational motion. This causes the telescopic end of the vertical rod head 30 to retract inward while rotating clockwise around the connection point of the second shaft connector 302. This causes the first bracket 306 to disengage from the second bracket 322, and the telescopic rod 33 to move as a whole to be on the same vertical axis as the straight rod 323. At this time, the turntable 36 and the feeder 2 are activated simultaneously. With the help of the telescopic rod 33 and the straight rod 323, the turntable 36 drives the large ball joint 31 on the bottom sleeve 32 to rotate clockwise around the central axis of the turntable 36. At the same time, the feeder 2 drives the tool assembly 6 to rotate counterclockwise, causing the toothed material 354 to rotate around its own center while being processed by the rotating tooth-cutting head 651.

[0049] Before the above operation, the adjustment operation of the composite clamping assembly 3 can be performed as described above, so that the toothed material 354 rotates around its own center. Then, the spinning machine 4 is activated to spin the toothed material 354 beforehand. Then, the above operation is continued to realize the circumferential rotation toothing process of the toothed material 354.

[0050] During use, after the feeder 2 is adjusted and fixed to the tooth-cutting operation position according to the position and size of the toothed material 354, the tailstock tip rod 5 is activated to reach the same adjustment position axis as the feeder 2, extending and abutting against the free end of the tooth-cutting head 651. This ensures that the tooth-cutting head 651 can rotate and cut teeth normally. At the same time, the tip of the tailstock tip rod 5 is used to abut and position the tooth-cutting head 651 in the middle of the free end of the tooth-cutting head 651 on the same axis, thus stabilizing the entire tooth-cutting head 651 and preventing it from deviating when cutting teeth on the surface of the toothed material 354. This achieves the effect of preventing deviation and positioning, improving the cutting accuracy of the tooth-cutting head 651 and ensuring the cutting quality.

[0051] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 9 As shown, a first shaft connector 301 is hinged to the top of the vertical rod head 30. The vertical rod head 30 is connected to the telescopic rod 33 through the first shaft connector 301.

A second bracket 322 is threadedly installed on the bottom end of the vibrating body 321. A straight rod 323 is telescopically connected to one side of the inner side of the bottom end of the bottom sleeve 32. A spring disc 324 is connected to the end of the straight rod 323 facing the bottom sleeve 32. The end of the spring disc 324 away from the straight rod 323 is connected to the bottom sleeve 32. The second bracket 322 can be inserted into the first bracket 306. The straight rod 323 is connected to the telescopic end of the telescopic rod 33 through the second shaft connector 302.

[0053] The rim member 34 includes a base ring 341 fitted and installed at the center of the top of the machine tool 1. The base ring 341 is fitted around the large ball joint body 31. A reinforcing ring 342 is connected to the outer edge of the base ring 341, and a second sealing ring 345 is connected to the inner edge of the base ring 341. Rubber rings 343 are installed on both sides of the surface of the reinforcing ring 342. A first sealing ring 344 is fixedly connected to the end of the reinforcing ring 342 away from the base ring 341. The ends of the first sealing ring 344 and the second sealing ring 345 away from each other are both attached to the large ball joint body 31.

[0054] The precision clamping assembly 35 includes a rotating electric gripper 351 threaded onto a large ball joint 31. An outer flange 352 is fitted onto the outer surface of the rotating electric gripper 351. A rotating disk 353 is rotatably connected to the top of the rotating electric gripper 351. The rotating disk 353 is rotatably mounted to the rotating electric gripper 351. A toothed material 354 is mounted on the top of the rotating disk 353. A bolt sleeve 355 is inserted into the middle of the top of the toothed material 354. A tightening device is threaded onto the bottom end of the bolt sleeve 355. A base block 357 is installed at the bottom of the rod 356 and the toothed material 354. A positioning ring 358 is installed at the bottom of the base block 357. An additional corner claw 359 is installed around the positioning ring 358. The additional corner claw 359 is installed on the rotating disk 353. Three sets of electric grippers 350 are installed in a circular array on the top of the rotating disk 353 for gripping and clamping the base block 357. The bottom end of the tightening rod 356 passes through the base block 357 and the positioning ring 358 and is threadedly installed on the rotating disk 353.

[0055] A fan block 81 is fixedly connected to the inner wall of the positioning ring 358. A central ring 82 is installed in the middle of the inner side of the positioning ring 358. The central ring 82 is fixedly connected to the positioning ring 358 through the fan block 81. A base 83 is threadedly installed in the middle of the top of the rotating disk 353. The tightening rod 356 is respectively inserted through the central ring 82 and the base 83. Three cone blocks 84 are fixedly installed in a circular array at the top of the rotating disk 353. The cone blocks 84 can be fitted between the fan block 81 and the central ring 82.

[0056] In use, the drive rail 37 automatically adjusts and changes the specific position of the straight rail 39 on the turntable 36. With the connection between the telescopic rod 33 and the straight rod 323 and the bottom of the base sleeve 32, the angle between the axis of the large ball joint 31 and the plane at the top of the machine tool 1 changes. Thus, when the turntable 36 rotates, it drives the toothed material 354 to perform an eccentric rotational motion. This adaptively changes the toothing position of the feed machine 2, and the toothing head 651 can complete the toothing processing at different heights on the surface of the toothed material 354. The toothed material 354 can be processed into various special irregular toothed parts, realizing the toothing processing of toothed parts of different models and shapes. It meets the special use requirements of different structural components, solves the problem that traditional toothing machines can only process conventional toothed parts with a single shape, realizes multi-purpose use, and enhances the overall practicality of the toothing machine.

[0057] After the gear grinding is completed, the turntable 36 is turned off. Under the control of the translational movement of the drive rail 37, the straight rail 39 is moved away from the guide sleeve 38, and finally the first clamp 306 is reinserted into the bottom of the second clamp 322. By activating the vibrator 321, the second clamp 322 and the first clamp 306 are driven to impact each other from top to bottom. The elastic extension and contraction of the straight rod 323 at the bottom of the bottom sleeve 32 can be used to counter-impact the bottom of the bottom sleeve 32, thereby transmitting the impact force to the precision clamping assembly 35 of the large ball joint 31. This can shake off the debris attached to the precision clamping assembly 35, the tooth strand 354 and the large ball joint 31 onto the machine tool 1, realizing the automatic shaking off and cleaning of debris on the surface of the composite clamping assembly 3, avoiding the accumulation of debris on the composite clamping assembly 3 and affecting the subsequent precision machining of irregular gear parts.

[0058] The outer ring 352 is fitted onto the rotating electric gripper 351, increasing the outermost diameter of the rotating electric gripper 351 surface. This intercepts and blocks debris outside the gap between the rotating electric gripper 351 and the large ball joint 31, preventing debris from accumulating in this gap and affecting the loading, unloading, and operation of the rotating electric gripper 351 on the large ball joint 31. At the same time, it guides the debris to the surface of the large ball joint 31, making it easier for the debris to fall onto the machine tool 1 and for subsequent collection and cleaning of the debris.

[0059] By having the first sealing ring 344 and the second sealing ring 345 together form a ring tightly attached to the surface of the large ball joint 31, the debris falling on the surface of the large ball joint 31 can be effectively guided to the machine tool 1. Furthermore, by utilizing the torsional force of the outermost ring 342 on the overall torsional direction of the first sealing ring 344, it can be ensured that when the large ball joint 31 undergoes eccentric torsional changes inside the machine tool 1, the first sealing ring 344 and the second sealing ring 345 can always be attached to the surface of the large ball joint 31, preventing debris from clogging the gap between the large ball joint 31 and the machine tool 1. This ensures that the large ball joint 31 will not be disturbed by debris during torsional movements in any direction on the machine tool 1.

[0060] By utilizing the rubber ring 343 installed on the surface of the rib ring 342, debris falling onto the rib ring 342 can be bounced away, reducing the impact damage to the surface of the rib ring 342 when debris falls off, while allowing debris to accumulate away from the periphery of the large ball joint 31. At the same time, by using the first sealing ring 344 and the second sealing ring 345, even if the outermost first sealing ring 344 is damaged or flipped outward, the second sealing ring 345 can continue to intercept and guide the debris, providing double protection to prevent debris from falling and clogging the gap between the large ball joint 31 and the machine tool 1.

[0061] By rotating the electric gripper 351 to drive the rotating disk 353 to rotate, the orientation of the toothed material 354 facing the tooth-cutting head 651 can be automatically adjusted. The initial tooth-cutting position of the tooth-cutting head 651 on the toothed material 354 can be automatically controlled. At the same time, it can also perform return tooth-cutting on local teeth, realizing secondary fine tooth-cutting processing on the already-cut parts. It can not only remove some of the debris blocking the tooth gaps, but also perform secondary re-cutting on the formed teeth, further improving the tooth-cutting accuracy.

[0062] By using the corner claw 359 to limit the positioning ring 358 in three directions, combined with the insertion of the cone block 84 between the sector block 81 and the central ring 82, the base 83 achieves overall positioning assembly of the positioning ring 358, providing a stable clamping and positioning platform for the bottom of the base block 357. Subsequently, combined with the electric gripper 350 to automatically clamp and limit the base block 357 placed on top of the positioning ring 358, the base block 357 can provide a precise positioning structure for the threaded positioning of the toothed material 354 on the rotating disk 353, preventing the toothed material 354 from shifting or shaking on the rotating disk 353, while also... By inserting the toothed material 354 onto the tensioning rod 356, and then threading the bolt sleeve 355 into the middle of the top of the toothed material 354 and connecting it to the tensioning rod 356, the toothed material 354 can be conveniently and precisely positioned on the rotating disk 353. This ensures that the toothed material 354 can always remain in a stable state for the toothing head 651 to perform toothing processing, further guaranteeing the fineness of the toothing processing of the toothed material 354. Furthermore, under this high-precision positioning and clamping installation guarantee structure, the toothing head 651 can also perform toothing processing on toothed materials 354 with different wall thicknesses.

[0063] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 10 to 15 As shown, a corner block 621 is fixedly connected to the end of the corner seat 62 away from the sleeve 61. The U-shaped piece 63 is fixedly connected to the corner seat 62 through the corner block 621. An opening is provided on one side of the outer surface of the sleeve 61. A second blade cylinder 611 is threaded on the outer surface of the sleeve 61. The second blade cylinder 611 is installed on the side away from the opening. A push rod 612 is installed at the output end of the second blade cylinder 611. The push rod 612 can move in and out of the opening through the second blade cylinder 611. A double-sided tongue lock 613 is installed at the connection between the sleeve 61 and the feeder 2. The double-sided tongue lock 613 is installed as a whole inside the opening. A square pin 614 is inserted in the middle of the double-sided tongue lock 613. The double-sided tongue lock 613 is installed with the sleeve 611 through the square pin 614.

[0064] The U-shaped component 63 includes a U-shaped body 631 fixedly connected to the corner seat 62 by a corner block 621. A lock hole 632 is provided through the U-shaped body 631. A guide tongue groove 633 is provided on the side of the lock hole 632. An unlocking cavity 634 is provided through the interior of the U-shaped body 631. The lock hole 632 and the guide tongue groove 633 are both connected to the unlocking cavity 634.

[0065] A double stopper rod 641 is installed at one end of the first blade cylinder 64 near the U-shaped body 631. A locking pin head 642 is threaded onto the other end of the double stopper rod 64 away from the first blade cylinder 64. The locking pin head 642 is telescopically installed with the first blade cylinder 64 via the double stopper rod 641. The locking pin head 642 is inserted into the inside of the unlocking cavity 634 via the double stopper rod 641.

[0066] The tooth-cutting cutter 65 includes a tooth-cutting head 651. A head rod 652 is fixedly connected to one end of the tooth-cutting head 651 near the sleeve fitting 61. The middle part of the head rod 652 is pinned to the clamp 66. The head rod 652 can swing in the middle of the U-shaped body 631 through the cooperation of the corner seat 62 and the clamp 66. A double-headed spring tongue 653 is spring-loaded onto the head rod 652. The double-headed spring tongue 653 can be squeezed and compressed into the return rod 652 from the lock hole 632 by the locking pin head 642. A semi-hinged head 656 is installed on the side of the head rod 652 away from the tooth-cutting head 651. The head rod 652 is hinged to the push rod 612 via the semi-hinged head 656. The end of the head rod 652 away from the toothed head 651 is equipped with a sliding wall tooth 657. The head rod 652 is limited and installed with the double-sided tongue lock 613 through the sliding wall tooth 657. The edges of the sliding wall tooth 657 and the double-sided tongue lock 613 that mesh with each other are rounded to facilitate the movable engagement between the head rod 652 and the double-sided tongue lock 613. This allows the tail end of the head rod 652 to be positioned by the double-sided tongue lock 613 while simultaneously sliding past the end of the double-sided tongue lock 613 and disengaging from the cavity.

[0067] Before the tooth-cutting process, the push rod 612 can be extended by activating the second blade cylinder 611. This allows the sliding tooth 657 at the tail end of the head rod 652 to slide through the protrusion at the end of the double-sided tongue lock 613 and be pushed out of the opening of the sleeve 61. This causes the head rod 652 to rotate counterclockwise around the axis of the positioning rod 67, while one end of the tooth-cutting head 651 shifts away from the toothed material 354. This means that the entire tooth-cutting head 651 is no longer completely tangent to the surface of the toothed material 354, but rather the part of the tooth-cutting head 651 closest to the head rod 652 is... The toothed material 354 is in contact with each other, and the depth of tooth cutting between the toothed cutter on the toothed head 651 and the surface of the toothed material 354 is different. This can avoid the front-side tangential tooth cutting of the toothed material 354 by the toothed head 651 in conventional operation, and can also achieve tooth cutting of different depths on the toothed material 354. At the same time, the tooth cutting operation part of the toothed head 651 can be flexibly switched, and the offset position of the toothed head 651 on the feeder 2 can be locally adjusted to cooperate with the composite clamping assembly 3 for tooth cutting of toothed materials 354 with different shapes and sizes.

[0068] During the use of the tool assembly 6, the sliding engagement of the double-sided tongue lock 613 with the sliding wall tooth 657 can assist the push rod 612 in returning the entire sleeve 61 to the central axis of the opening, ensuring that the tooth-cutting head 651 can perform normal tooth-cutting processing on the toothed material 354 under the rotation drive of the feeder 2.

[0069] During the offset adjustment of the head rod 652, the double-headed spring tongue 653 can move inside each locking hole 632 under the guidance of the guide tongue groove 633. By using the double-headed spring tongue 653 to move and insert in the locking hole 632, the head rod 652 is positioned and locked on the U-shaped body 631, ensuring that the position of the tooth-cutting head 651 will not shift during tooth cutting, and ensuring the tooth cutting accuracy of irregular toothed parts.

[0070] When it is necessary to push the head rod 652 out from the inside of the lock hole 632 and restore the head rod 652 to its initial vertical cross position inside the U-shaped body 631, the first blade cylinder 64 can be activated to drive the double plug rod 641 to extend in the unlocking cavity 634. The locking pin head 642 will push the double-headed spring tongue 653 out from the lock hole 632, so that both ends of the double-headed spring tongue 653 retract into the head rod 652 at the same time. At the same time, the first blade cylinder 64 is activated to retract, so that the axis of the head rod 652 coincides with the axis of the opening cavity, thus realizing the normal use state setting of the head rod 652.

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.
