Description

Technical Field

[0001] This utility model relates to the field of gear manufacturing technology, specifically a gear burr removal device. Background Technology

[0002] Gear burrs are tiny protrusions of metal that appear during gear manufacturing due to cutting, grinding, or other processing methods. Burrs can affect the meshing accuracy, service life, running smoothness, and wear resistance of gears; therefore, burr removal is an important step in gear manufacturing.

[0003] For example, a deburring device for automotive gear manufacturing, disclosed in CN222537151U, includes a frame. Cylinders are fixedly mounted at the top and bottom of the frame. A connecting frame is fixedly mounted at the end of the inner rod of the cylinder. A motor is fixedly mounted below the connecting frame. Grinding discs are fixedly mounted on the motor's shaft. A through slot is formed in the frame, opposite to two grinding discs. A fan is fixedly mounted within the through slot. By extending and retracting the cylinders, the spacing between the grinding discs is controlled, allowing for deburring of gears of different sizes. It offers good versatility, allows simultaneous operation from both top and bottom, and has high deburring efficiency, blowing away burrs during the deburring process.

[0004] The aforementioned patent proposes that by extending and retracting the cylinder, the spacing of the grinding disc can be controlled to remove burrs from gears of different sizes. However, in actual use, because the gears are not fixed in position, they are easily displaced by the rotation of the grinding disc during the deburring process, which affects the deburring effect and makes the use inconvenient. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figures 1-3 A gear burr removal device includes a motor 2 mounted on the top of a mounting base 1, a grinding disc 4 mounted on the output end of the motor 2, a blower 3 mounted on the top of the mounting base 1 and above the motor 2, an air conveying component 6 mounted on the top of the blower 3 and the bottom end of the air conveying component 6 being above the grinding disc 4, and a positioning component 5 mounted on one side of the mounting base 1 and below the grinding disc 4.

[0018] The positioning component 5 includes a side stop 51 and a grinding groove 52 formed on one side of the side stop 51. A cylinder 53 is installed below the grinding groove 52 and inside the body of the side stop 51. A mounting ring 54 is installed at the moving end of the cylinder 53. A moving frame 56 is installed on one side of the side stop 51.

[0019] The top of the movable frame 56 is provided with a top groove 561. An external plate 563 is installed on the top of the movable frame 56 and on one side of the top groove 561. An internally threaded tube 57 is installed on the upper part of the interior of the movable frame 56. One end of the internally threaded tube 57 is threadedly connected to a bolt shaft 58. An internally built-in plate 564 is installed on the lower part of the interior of the movable frame 56. A connecting strip 59 is installed on one end of the internally built-in plate 564 facing the side stop 51. The cooperation between the internally threaded tube 57 and the bolt shaft 58 can fix the gear.

[0020] A rolling cylinder 565 is movably installed inside the movable frame 56 and below the built-in plate 564. Positioning rods 562 are symmetrically installed on both sides of the upper end of the movable frame 56, and positioning holes 55 are symmetrically opened on both sides of the side block 51. An inner insert plate 566 is installed inside the movable frame 56 and above the built-in plate 564. The height of the positioning holes 55 is the same as the height of the positioning rods 562. The length of the inner insert plate 566 is greater than that of the built-in plate 564, which facilitates the centralized collection of burrs.

[0021] The air supply component 6 includes an air supply pipe 61 installed at the top of the blower fan 3. A horizontal pipe 62 is installed on the outer surface of the air supply pipe 61 facing the grinding disc 4. An exhaust pipe 63 is installed at the bottom of the horizontal pipe 62 above the grinding disc 4. A slot 64 is provided on the outer surface of the exhaust pipe 63 away from the grinding disc 4. An outer plate 563 is used in conjunction with the slot 64 to avoid burrs and restrict movement. The air supply component 6 can guide the air generated by the blower fan 3 in a directional manner.

[0022] In this embodiment: when the moving frame 56 is away from the side stop 51, the bolt shaft 58 can be rotated out from one end of the internal thread tube 57, and the gear can be placed at one end of the bolt shaft 58. Holding the bolt shaft 58, the gear is installed at one end of the internal thread tube 57. As the bolt shaft 58 rotates, the position of the gear is fixed by one end of the bolt shaft 58 and the internal thread tube 57. When the cylinder 53 retracts, it will pull the moving frame 56 to one side of the side stop 51. The rolling cylinder 565 located at the lower end of the moving frame 56 rotates to facilitate... The movable frame 56 carries the gear and moves to one side of the grinding disc 4. As the movable frame 56 moves, the outer plate 563 installed at the top of the movable frame 56 moves into the interior of the slot 64. When the grinding disc 4 rotates to deburr the gear, the air force generated by the fan 3 will clean the removed burrs through the air supply pipe 61, the horizontal pipe 62 and the exhaust pipe 63. The air supply component 6 and the positioning component 5 limit the range of burr movement to avoid accidental injury to the operator. After use, the burrs accumulate at the top of the inner plate 566 for easy centralized processing afterward.

[0023] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The top of the connecting bar 59 is provided with an inverted T-shaped groove 591, and an inverted T-shaped shaft 593 is movably installed inside the inverted T-shaped groove 591. The top of the inverted T-shaped shaft 593 is provided with a slanted groove 594, and a compression spring 595 is installed between the bottom end of the inverted T-shaped shaft 593 and the bottom end of the inverted T-shaped groove 591. The inverted T-shaped shaft 593 is used in conjunction with the mounting ring 54 to fix the position of the moving frame 56.

[0024] An inner groove 592 is provided on one side of the lower inner wall of the inverted T-shaped groove 591, and a side connecting block 596 is installed on one side of the lower end of the inverted T-shaped shaft 593. The side connecting block 596 is movably installed inside the inner groove 592 to limit the movement angle of the inverted T-shaped shaft 593.

[0025] In this embodiment: After the gear processing is completed, the inverted T-shaped shaft 593 is pressed down. The compression spring 595 deforms under the pressure of the inverted T-shaped shaft 593. The side block 596 installed on the lower end of the inverted T-shaped shaft 593 moves downward within the inner groove 592 to ensure that the inclined groove 594 at the top of the inverted T-shaped shaft 593 is in an inclined position. After the top of the inverted T-shaped shaft 593 moves down from the inside of the mounting ring 54, the movable frame 56 can be pulled out separately. The burrs collected by the inner insert plate 566 can be centrally processed. During installation, the positioning rod 562 is inserted into the positioning hole 55 to pre-align the installation of the moving frame 56. When the moving frame 56 is pushed to the side of the side block 51, the bottom end of the inclined groove 594 at the top of the inverted T-shaped shaft 593 faces the mounting ring 54. The inverted T-shaped shaft 593 moves downward due to the restriction of the mounting ring 54. When the middle of the inverted T-shaped groove 591 is aligned with the middle of the inner side of the mounting ring 54, the inverted T-shaped shaft 593 moves upward due to the push force of the compression spring 595, thus fixing the position of the moving frame 56.
