Description

Technical Field

[0001] This invention relates to the field of milling technology, specifically to a deburring device for milling thin gear plates. Background Technology

[0002] As precision transmission components, the geometric accuracy and surface quality of gear tooth profiles directly determine the smoothness, noise level, and service life of the entire transmission system. During gear cutting or forming, burr generation is unavoidable. These tiny metal protrusions distributed along the edges of the tooth surface, if not thoroughly removed, will cause tooth surface scoring, abnormal wear, and generate severe vibration and noise during meshing, and in severe cases, even lead to tooth breakage and other failures. Therefore, deburring is a crucial process in gear finishing.

[0003] In gear deburring, precise workpiece positioning is the cornerstone of ensuring machining results and quality. If there is a deviation in the gear's positioning within the fixture, it will directly cause a misalignment between the theoretical relative position of the deburring tool and the gear tooth profile. This minute misalignment is enough to cause a tool that should be precisely rounding or trimming the tooth edges to incorrectly contact the working tooth surface, thus creating grooves on the tooth surface or resulting in unnecessary material removal.

[0017] This invention provides a device for deburring thin gear plates during milling. It has the following beneficial effects:

[0018] I. The deburring device for milling thin plates of gears, by setting up a rolling screw device and a third connecting frame, constitutes a transverse feeding system for gear workpieces. The rolling screw device adopts a precision ball screw, which is driven by a servo motor to realize the precise positioning and smooth movement of the gear workpiece during the processing. Thus, during the transverse movement of the gear, it realizes two working states: positioning and unloading of the gear.

[0019] II. The deburring device for milling thin plates of gears constructs a gear rotation drive system by setting a first connecting frame and a drive mechanism. The first connecting frame provides stable support for the drive mechanism to ensure the accuracy of power transmission. The drive mechanism realizes precise indexing and rotation control of the gear workpiece through a specially designed transmission method.

[0020] III. The deburring device for milling thin gear plates consists of a second connecting frame and a milling mechanism, forming an execution system for deburring. The second connecting frame adopts a rigid design to ensure that no deformation occurs during processing. The milling mechanism utilizes the principle of milling. During operation, a drive wheel drives several milling cutters to rotate, so that the milling cutters come into contact with the gear, effectively removing various burrs from the edge of the thin gear plate. At the same time, it can collect the debris generated during gear milling, preventing debris from flying everywhere.

[0021] IV. This gear thin plate milling deburring device achieves rapid positioning and reliable clamping of the gear workpiece by setting up a clamping mechanism and its positioning frame, a second anti-slip post and a round hole. The positioning frame is precisely designed according to the shape of the gear, providing additional anti-slip protection for the second anti-slip post. When the positioning frame contacts the gear, the second anti-slip post contacts the hole on the outer surface of the gear, thereby realizing the positioning of the gear. The round hole provides a docking interface for the drive mechanism to ensure effective power transmission.

[0022] V. This gear thin plate milling deburring device, through the setting of a limiting tube, a rubber ring, an anti-slip plate, and a connecting hole, constitutes a gear inner hole clamping system. The limiting tube enables the piston to slide stably in its inner cavity; the rubber ring expands under air pressure, thereby achieving uniform clamping with the gear inner hole; the anti-slip plate is made of hard rubber material, which has strong friction and enhances clamping reliability; the connecting hole establishes an air pressure channel to achieve precise control of clamping force, so that when the air pressure in the inner cavity of the limiting tube changes, the internal gas can enter the rubber ring, thereby causing the rubber ring to expand.

[0038] 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.

[0039] like Figures 1-10As shown, the present invention provides a technical solution: a deburring device for milling thin gear plates, comprising a base plate 1, a support frame 3 welded to the upper surface of the base plate 1, a rolling screw device 4 for providing lateral driving force fixed to the inner wall of the support frame 3, a third connecting frame 10 fixed to the movable end of the rolling screw device 4, a clamping mechanism 6 for positioning the gear fixed to the end of the third connecting frame 10, and a discharge port 9 fixed to the outer surface of the support frame 3. By setting the base plate 1 and the support frame 3, a stable foundation platform and main support structure are provided for the entire deburring device. The base plate 1 is made of thickened steel plate and precision machined to ensure the accuracy of the installation position of each component; the support frame 3 adopts a box beam structure, which has sufficient rigidity and vibration resistance, providing a precise installation reference for the rolling screw device 4. By setting up the rolling screw device 4 and the third connecting frame 10, a transverse feeding system for the gear workpiece is formed. The rolling screw device 4 adopts a precision ball screw and is driven by a servo motor to achieve precise positioning and smooth movement of the gear workpiece during the processing. Thus, during the transverse movement of the gear, two working states are achieved: positioning and unloading of the gear. The third connecting frame 10 serves as a load-bearing structure, reliably connecting the clamping mechanism 6 to the drive system.

[0040] The first connecting frame 2 is welded to the upper surface of the base plate 1, and a drive mechanism 5 for driving the gear rotation is fixed at the top of the first connecting frame 2. By setting the first connecting frame 2 and the drive mechanism 5, a gear rotation drive system is constructed. The first connecting frame 2 provides stable support for the drive mechanism 5, ensuring the accuracy of power transmission; the drive mechanism 5 achieves precise indexing and rotation control of the gear workpiece through a specially designed transmission method.

[0041] The second connecting frame 7 is welded to the side of the upper surface of the base plate 1, and a milling mechanism 8 for removing burrs from the gear plate is fixed at the top of the second connecting frame 7. The second connecting frame 7 and the milling mechanism 8 together form a burr removal execution system. The second connecting frame 7 is rigidly designed to ensure no deformation occurs during processing; the milling mechanism 8 has a milling function, effectively removing various burrs from the edge of the gear plate, and simultaneously collecting the debris generated during gear milling to prevent debris from flying everywhere.

[0042] The clamping mechanism 6 includes a positioning frame 64, on the outer surface of which a second anti-slip post 65 is welded. A circular hole 66 is also provided on the outer surface of the positioning frame 64. By setting up the clamping mechanism 6 and its positioning frame 64, second anti-slip post 65, and circular hole 66, rapid positioning and reliable clamping of the gear workpiece are achieved. The positioning frame 64 is precisely designed according to the gear's shape, providing additional anti-slip protection for the second anti-slip post 65. When the positioning frame 64 contacts the gear, the second anti-slip post 65 contacts the hole on the gear's outer surface, thereby achieving gear positioning. The circular hole 66 provides a docking interface for the drive mechanism 5, ensuring effective power transmission.

[0043] The drive mechanism 5 includes a fourth connecting frame 51, which is welded to the upper surface of the base plate 1 on the side away from the first connecting frame 2. The top of the fourth connecting frame 51 is penetrated by an inner quadrangular tube 52. A quadrangular rod 53 is slidably connected to the inner cavity of the inner quadrangular tube 52. A sub-branch 54 is welded to the end of the quadrangular rod 53. A first extrusion column 55 is welded to the side of the sub-branch 54 away from the quadrangular rod 53. A first support rod 56 is welded to the end of each sub-branch 54. A first anti-slip column 57 is welded to the end of each first support rod 56. By setting up a fourth connecting frame 51, an inner quadrangular tube 52, a quadrangular rod 53, a sub-support 54, a first pressing column 55, a first support rod 56, and a first anti-slip column 57, a positioning and clamping assembly for the pre-processed gear is formed. The fourth connecting frame 51 provides stable support for the entire positioning and clamping assembly for the pre-processed gear. The inner quadrangular tube 52 can provide positioning support for the quadrangular rod 53. The first anti-slip column 57 increases friction to prevent the pre-processed gear from slipping during positioning with the clamping mechanism 6. In use, the hole on the outer surface of the gear to be milled is brought into contact with the first anti-slip column 57, thereby connecting the gear with the sub-support 54. Then, the quadrangular rod 53 is inserted into the inner cavity of the inner quadrangular tube 52.

[0044] The drive mechanism 5 also includes a first stepper motor 58, which is welded to the end of the first connecting frame 2 away from the base plate 1. The output end of the first stepper motor 58 is equipped with a first rotating rod 59 via a coupling. The end of the first rotating rod 59 is inclined. A connecting sleeve 510 is welded to the outer surface of the first rotating rod 59. A second support rod 511 is welded to the outer surface of the connecting sleeve 510. A second extrusion column 512 is welded to the end of the second support rod 511. The second extrusion column 512 is frictionally adapted to the circular hole 66 opened on the outer surface of the positioning frame 64. The drive mechanism 5's rotational power system is formed by setting up a first stepper motor 58, a first rotating rod 59, a connecting sleeve 510, a second support rod 511, and a second extrusion column 512. The first stepper motor 58 provides precise angular displacement control, enabling accurate rotation of the gear. This allows the gear rack to accurately contact the milling mechanism 8 during gear milling. The inclined end design of the first rotating rod 59 enables it to press the locking component of the clamping mechanism 6 when in contact with the inside of the clamping mechanism 6, thereby loosening the locking component and allowing the finished gear to be discharged. The connecting sleeve 510 serves as a connecting hub, causing the first rotating rod 59 to rotate along with the second support rod 511. The second support rod 511 ensures the accurate positioning of the second extrusion column 512. The frictional engagement between the second extrusion column 512 and the circular hole 66 enables effective power transmission while allowing for a certain degree of positional compensation.

[0045] A first connecting ring 63 is welded to the outer surface of the positioning frame 64. A first rolling bearing 62 is fixed to the outer surface of the first connecting ring 63. A fixing ring 61 is welded to the outer ring of the first rolling bearing 62. The fixing ring 61 is welded to the end of the third connecting frame 10 away from the movable end of the rolling screw device 4. The first connecting ring 63, the first rolling bearing 62, and the fixed ring 61 form a rotating support system for the clamping mechanism 6. The first connecting ring 63 serves as the bearing mounting base. The first rolling bearing 62 is a precision-grade angular contact ball bearing, which can withstand both radial and axial loads, ensuring that the positioning frame 64 drives the gear to rotate stably. The fixed ring 61 reliably mounts the entire rotating system on the third connecting frame 10, forming a stable support structure. At the same time, it allows the positioning frame 64 to move laterally along with the moving end of the rolling screw device 4. A limit tube 613 is welded to the inner wall of the positioning frame 64. A rubber ring 611 is fitted on the outer surface of the positioning frame 64. Anti-slip pieces 612 are fixed on the outer surface of the rubber ring 611. There are several anti-slip pieces 612, which are evenly distributed on the outer surface of the rubber ring 611. A connecting hole is provided between the outer surface of the positioning frame 64 and the limit tube 613. This connecting hole is used to connect the limit tube 613 and the rubber ring 611. A gear inner hole clamping system is formed by setting a limiting tube 613, a rubber ring 611, an anti-slip plate 612, and a connecting hole. The limiting tube 613 enables the piston 614 to slide stably in its inner cavity. The rubber ring 611 expands under air pressure, thereby achieving uniform clamping with the gear inner hole. The anti-slip plate 612 is made of hard rubber, which has strong friction and enhances clamping reliability. The connecting hole establishes an air pressure channel to achieve precise control of the clamping force. When the air pressure in the inner cavity of the limiting tube 613 changes, the internal gas can enter the rubber ring 611, thereby causing the rubber ring 611 to expand.

[0046] A piston 614 is slidably connected to the inner cavity of the limiting tube 613. A straight tube 616 is welded to the outer surface of the piston 614, penetrating the limiting tube 613. A third spring 615 is sleeved on the outer surface of the straight tube 616 within the inner cavity of the limiting tube 613. One end of the third spring 615 is welded to the outer surface of the piston 614, and the other end is welded to the inner wall of the limiting tube 613. By setting up the piston 614, the straight tube 616, and the third spring 615, a pneumatic clamping power execution system is formed. During the process of the clamping mechanism 6 approaching the pre-processed gear, the first extrusion column 55 extrudes the piston 614, which moves under the extrusion force and extrudes the gas inside the limiting tube 613. The straight tube 616 transmits the motion, and the third spring 615 provides a reliable restoring force to ensure that the workpiece is quickly released when the air pressure is released, thereby achieving the effect of unloading the milled gear.

[0047] A support frame 67 is welded to the outer surface of the positioning frame 64. A track tube 68 is welded to the end of the support frame 67. A locking rod 69 is slidably connected to the inner cavity of the track tube 68. The end of the locking rod 69 extending to the outer surface of the track tube 68 is wedge-shaped. A sliding strip 617 is symmetrically welded to the outer surface of the straight tube 616. The sliding strip 617 is slidably connected to the inner wall of the limiting tube 613. A positioning hole 618 is opened on the outer surface of the straight tube 616. The wedge shape at the bottom of the locking rod 69 is frictionally matched with the positioning hole 618 opened on the outer surface of the straight tube 616. A second spring 610 is welded to the end of the locking rod 69 away from the straight tube 616. The top of the second spring 610 is welded to the top of the inner wall of the track tube 68. A safety locking system is formed by setting up a support frame 67, a track tube 68, a locking rod 69, a sliding bar 617, a positioning hole 618, and a second spring 610. The support frame 67 and the track tube 68 provide precise guidance for the locking rod 69, enabling it to move stably vertically up and down within the inner cavity of the track tube 68. The wedge-shaped end of the locking rod 69 achieves an automatic locking function. Simultaneously, when the inclined end of the first rotating rod 59 is inserted into the straight tube 616, the wedge-shaped end of the locking rod 69 disengages from the straight tube 616. The sliding bar 617 ensures that the straight tube 616 does not rotate during movement. The positioning hole 618 provides a locking position for the locking rod 69. The second spring 610 keeps the locking rod 69 in a constantly locked state, ensuring processing safety.

[0048] The milling mechanism 8 includes a second stepper motor 81 and a fifth connecting frame 84. The second stepper motor 81 is fixed at the top of the second connecting frame 7. The output end of the second stepper motor 81 is connected to a second rotating rod 82 via a coupling. A rotating cylinder 83 is welded to the end of the second rotating rod 82. The fifth connecting frame 84 is welded to the upper surface of the base plate 1. A support ring 85 is welded to the top of the fifth connecting frame 84. The main frame of the milling mechanism 8 is formed by setting up a second stepper motor 81, a second rotating rod 82, a rotating cylinder 83, a fifth connecting frame 84, and a support ring 85. The second stepper motor 81 provides milling power, and its speed is adjustable to adapt to different materials. The second rotating rod 82 transmits torque, and when the output end of the second stepper motor 81 rotates, it causes the rotating cylinder 83 to rotate. The rotating cylinder 83 serves as the main body for tool mounting. The fifth connecting frame 84 provides a stable foundation for the support ring 85. The support ring 85 supports the rotating cylinder 83 through a second rolling bearing 86 to ensure the stability of the milling process. The second rolling bearing 86 is fixed to the inner wall of the support ring 85, and a second connecting ring 87 is fixed to the inner ring of the second rolling bearing 86. The second connecting ring 87 is welded to the outer surface of the rotating cylinder 83. An internal threaded ring 88 passes through the end of the rotating cylinder 83 away from the second rotating rod 82, and a sealing cap 89 is threadedly connected to the inner cavity of the internal threaded ring 88. By setting a second rolling bearing 86, a second connecting ring 87, an internal threaded ring 88, and a sealing cover 89, a support and sealing system for the rotating cylinder 83 is formed, providing precise rotational support for the second rolling bearing 86; the second connecting ring 87 connects the second rolling bearing 86 to the rotating cylinder 83; the internal threaded ring 88 facilitates the installation of the sealing cover 89, and also facilitates the removal of the sealing cover 89 to discharge debris from the inside of the rotating cylinder 83; a connecting box 810 penetrates the outer surface of the rotating cylinder 83, and there are several connecting boxes 810, which are spaced apart on the outer surface of the rotating cylinder 83; a milling cutter 812 is fixed on the outer surface of the connecting box 810, and a connecting port 811 is opened on the outer surface of the connecting box 810, which is used to connect the connecting box 810 to the inner cavity of the milling cutter 812. By setting up a connecting box 810, a milling cutter edge 812, and a connecting port 811, a multi-station milling system is formed. The connecting box 810 serves as a tool mounting unit and can install milling cutters of different specifications. The milling cutter edge 812 provides a cutting edge exit, and its angle has been optimized. Multiple connecting boxes 810 are distributed at intervals to realize a combination of roughing and finishing, thereby improving machining efficiency and quality.

[0049] Working principle: In use, the operator aligns the hole on the outer surface of the gear to be treated with the first anti-slip post 57, connects the gear to the bracket 54, and then inserts the quadrangular rod 53 into the inner cavity of the inner quadrangular tube 52. Then, the operator controls the rolling screw device 4 to move the movable end of the third connecting frame 10 and the clamping mechanism 6 towards the pre-positioned gear. During this movement, the second anti-slip post 65 on the outer surface of the positioning frame 64 inserts into the hole on the gear surface. Simultaneously, as the positioning frame 64 moves, the piston 614 and the first pressing post 55... The piston 614 contacts the end of the straight tube 616, causing it to move within the cavity of the limiting tube 613. This allows the gas in the cavity of the limiting tube 613 to flow through the connecting hole into the rubber ring 611, causing the rubber ring 611 to expand and the anti-slip plate 612 to tightly contact the inner ring of the gear, thus completing the positioning and clamping of the gear. At this time, under the action of the second spring 610, the locking rod 69 inserts the wedge-shaped block at its bottom end into the positioning hole 618 on the outer surface of the straight tube 616, preventing the piston 614 from rebounding. Then, the control... The movable end of the rolling screw device 4 moves, positioning the gear directly below the milling mechanism 8. During this process, the second extrusion column 512 is located at the circular hole 66 on the outer surface of the positioning frame 64. Simultaneously, the first stepper motor 58 and the second stepper motor 81 are started, causing them to move rhythmically. During operation, the milling cutter 812 contacts the burrs on the gear rack, milling off the burrs and allowing them to fall into the inner cavity of the rotating cylinder 83 through the connecting port 811. After the gear is milled, the first stepper motor 58 and the second stepper motor 81 are stopped. The moving end of the drive screw device 4 moves away from the fourth connecting frame 51. During this process, the inclined part of the end of the first rotating rod 59 is pressed against the wedge-shaped part of the locking rod 69, causing the locking rod 69 to disengage from the positioning hole 618 on the outer surface of the straight tube 616. Under the action of the third spring 615, the piston 614 rebounds, and the rubber ring 611 stops expanding. At the same time, the second extrusion column 512 passes through the round hole 66 on the outer surface of the positioning frame 64 and is pressed against the gear, so that the milled gear falls into the inner cavity of the discharge port 9 and is finally collected.
