[0001] The utility model relates to the technical field of gear processing, in particular to mechanical equipment for efficiently removing gear burrs. Background Art

[0002] Burrs are a common problem in gear processing, usually appearing on the gear tooth surface, tooth root and tooth top. Burrs not only affect the appearance quality of the gear, but may also cause poor gear meshing, increase friction and wear, and ultimately affect transmission efficiency and service life. Therefore, removing gear burrs is an important step to ensure gear quality.

[0003] Although the prior art has developed a variety of gear deburring methods and equipment, there are still some shortcomings and limitations:

[0004] Manual deburring: The traditional manual deburring method relies on the workers’ experience and skills, which is complicated and inefficient.

Different tooling fixtures need to be replaced for gears of different models and sizes, increasing the adjustment and maintenance costs of the equipment.

[0007] Therefore, the utility model proposes a mechanical device for efficiently removing gear burrs to solve the above problems. Utility Model Content

[0057] Please refer to the instruction manual Figure 1-Figure 7 The utility model provides a mechanical device for efficiently removing burrs from gears, comprising:

[0058] The base 1 serves as the foundation of the entire equipment, on which the structure of the top platform 5 is fixed and supported by the pillars 11 to ensure the stability of the top platform 5. A gear positioning mechanism 3 is arranged between the base 1 and the top platform 5. A lifting cylinder 2 is installed at the bottom center of the base 1 to drive the gear positioning mechanism 3 to rise and fall. The gear 4 to be processed is placed on the gear positioning mechanism 3. The abrasive fluid storage tank 8 on the top platform 5 stores abrasive fluid, and the extrusion of the abrasive fluid is controlled by the fluid extrusion discharge mechanism 9. The design of the guide hole 51 allows the abrasive fluid to be evenly distributed and introduced into the guide channel formed by the upper docking cover 6 and the gear positioning mechanism 3, thereby realizing the deburring operation of the gear.

[0059] The gear positioning mechanism 3 includes a gear placement seat 32 connected to the top end of the piston rod of the lifting cylinder 2, a cylindrical air guide cover 31 distributed on the outside of the gear placement seat 32, a plurality of side connecting frames 33 connecting the gear placement seat 32 and the inner wall of the cylindrical air guide cover 31, and a gear centering assembly 34 installed inside the top surface of the gear placement seat 32.

[0060] Among them, the gear placement seat 32 ensures that the gear 4 to be processed is placed firmly. The design of the cylindrical air guide hood 31 helps to guide the abrasive fluid to flow to the tooth surface of the gear 4 to be processed, and the side connecting frame 33 strengthens the connection strength between the gear placement seat 32 and the cylindrical air guide hood 31. The gear centering assembly 34 drives the driving screws 343 on both sides to rotate synchronously through the dual-axis reduction motor 342, thereby expanding the screw sleeves 344 on both sides outward, which can realize the operation of driving the inner ring tightening arms 345 on both sides to move outward, realize the precise tightening of the gear inner ring, and ensure the center positioning and stability of the gear during the processing process.

[0061] The cylindrical flow guide cover 31 is butted against the lower end surface of the upper butt cover 6 when the lifting cylinder 2 is in the lifting state, forming an abrasive fluid guide channel.

[0062] Among them, the docking design of the cylindrical guide cover 31 and the upper docking cover 6 forms a closed abrasive fluid guide channel to prevent the abrasive fluid from overflowing during the processing process, while ensuring that the abrasive fluid can concentrate on the tooth surface of the gear to improve the deburring effect.

[0063] The gear centering assembly 34 includes a transverse mounting groove 341 distributed on the top surface of the gear placement seat 32, a dual-axis reduction motor 342 installed in the inner center of the transverse mounting groove 341, driving screws 343 respectively connected to the output ends on both sides of the dual-axis reduction motor 342, screw sleeves 344 respectively threadedly sleeved on the driving screws 343 on both sides, and inner ring clamping arms 345 respectively connected to the top tube walls of the screw sleeves 344 on both sides, and the two inner ring clamping arms 345 are clamped on the two side walls of the inner ring of the gear 4 to be processed.

[0064] The transverse mounting groove 341 in the gear centering assembly 34 is designed to have sufficient depth and width to accommodate the dual-axis reduction motor 342 and the driving screw 343. The driving screw 343 is connected to the inner ring tightening arm 345 through the screw sleeve 344, and the tightening force of the inner ring tightening arm 345 can be precisely controlled by adjusting the rotation of the driving screw 343 to adapt to gears of different sizes.

[0065] There are a plurality of material guide holes 51 distributed radially with the center of the top platform 5 as the center of the circle, and the plurality of material guide holes 51 are connected to the abrasive fluid storage tank 8 and the interior of the upper docking cover 6 .

[0066] The radial distribution design of the guide holes 51 enables the abrasive fluid to flow evenly to the gear from multiple directions, ensuring that each tooth surface of the gear can be fully deburred. The guide holes 51 are connected with the abrasive fluid storage tank 8 and the upper docking cover 6 to ensure the smooth flow of the abrasive fluid.

[0067] The gear clamping assembly 7 includes a clamping cone 71 distributed directly below the center of the top platform 5, a clamping spring 72 connecting the clamping cone 71 and the top platform 5, and a guide column 73 docked at the top center of the clamping cone 71. The upper end of the guide column 73 is slidably inserted into the center of the top platform 5, and the clamping spring 72 is sleeved on the outer side of the guide column 73.

[0068] The compression cone 71 in the gear compression assembly 7 is designed to match the central through hole of the gear, which can adapt to the central compression and positioning operation of gears of different models, and realize uniform compression of the gear through the action of the tension spring 72. The design of the guide column 73 ensures the precise movement of the compression cone 71 in the vertical direction.

[0069] The fluid extrusion discharging mechanism 9 includes a downward pressure cylinder 91 installed at the top center of the abrasive fluid storage tank 8, and a structure that is slidably connected to the inside of the abrasive fluid storage tank 8 and docked with the bottom end of the piston rod of the downward pressure cylinder 91.

[0070] The downward pressure cylinder 91 in the fluid extrusion discharging mechanism 9 realizes the extrusion and release of the abrasive fluid by controlling the up and down movement of the piston rod. The sliding clamping structure ensures the stable movement of the discharging mechanism inside the abrasive fluid storage tank 8, while ensuring the uniform and continuous supply of the abrasive fluid.

[0071] The legs 12 at the bottom of the base 1 are used to support the entire device.
