Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a deburring device for the surface of a tapered hub. Background Technique

[0002] Machining refers to a process of changing the shape, size or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. After the machining of the tapered hub is completed, burrs will remain on the surface of the tapered hub. The burrs not only affect the quality of the tapered hub, but also easily cut the hands of operators, so it is necessary to deburr the surface of the machined tapered hub.

[0003] In the prior art, the content of the Chinese utility model with the publication number: CN215281258U discloses a deburring machine for an electric vehicle hub, including a deburring table.

A pushing device is movably installed on the robotic arm. The bottom end of the pushing device is rotatably connected to a grinding device. A plurality of cross chutes are opened on the upper surface of the deburring table. The first cylinder pushes the L-shaped base to move up and down, and the second cylinder can push the first motor to rotate in the rotating groove to adjust the angle, so as to realize deburring and grinding of the plane and the curved surface; the fixing block slides in the cross chute, and the installation height of the arc-shaped clamping block can be adjusted according to alloy hubs of different sizes, and then the fastening bolt is used to fix the arc-shaped clamping block, so as to make the clamping more stable; the second motor drives three driven bevel gears to rotate through the driving bevel gear, so that the lead screw rotates and drives the clamping device to slide along the cross chute to realize automatic clamping.

[0004] In the above technical solution, only one group of hubs can be processed at a time. If it is necessary to remove the burrs on the surfaces of multiple groups of hubs, individual operations need to be carried out, resulting in too low burr removal efficiency, which cannot meet the requirements of normal production and affects the supply efficiency of products.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The utility model provides a deburring device for the surface of a tapered hub as Figures 1 to 5 shown, which includes a processing box 1. At the top and bottom of the inner cavity of the processing box 1, mounting discs 2 are rotatably connected through rotating shafts. An installation shaft 3 is installed between the mounting discs 2, and multiple groups of tapered hub bodies 4 are sleeved on the outer side of the installation shaft 3.

[0024] Two groups of screw rods 5 are rotatably connected to the inner cavity of the processing box 1 through bearings. The outer sides of the screw rods 5 are threadedly connected with fixing blocks 6 through threaded sleeves. The inner sides of the fixing blocks 6 are fixed with movable frames 7. Through grooves 8 are formed around the movable frames 7. Rotating shafts 9 are rotatably connected to the inner cavities of the through grooves 8. Transverse brush cylinders 10 and vertical brush cylinders 11 are respectively fixed on the outer sides of the rotating shafts 9. A fixing box 12 is fixed at the bottom of the processing box 1, and a driving component 13 for synchronously driving the screw rods 5 is arranged in the inner cavity of the fixing box 12;

[0025] The second driving motor 16 drives the mounting disc 2 to rotate, and then the mounting disc 2 is connected to the installation shaft 3 to rotate multiple groups of tapered hub bodies 4 mounted on the installation shaft 3. Subsequently, the vertical brush cylinder 11 inside the movable frame 7 clears the burrs between the tapered hub bodies 4 from top to bottom. Then, the third driving motor 22 drives the transverse brush cylinder 10 to rotate through the rotating shaft 9 to clear the burrs inside the external teeth of the tapered hub body 4, comprehensively clearing the burrs on the surface of the tapered hub body 4, making the surface of the tapered hub body 4 smooth. At the same time, multiple groups of tapered hub bodies 4 can be cleared at one time, improving the deburring efficiency of the surface of the tapered hub body 4.

[0026] The driving component 13 includes a first driving motor 131 fixed in the inner cavity of the fixing box 12. A first gear 132 is fixed on the output shaft of the first driving motor 131. One end of the screw rod 5 penetrates into the inner cavity of the fixing box 12 and is fixed with a second gear 133. The second gear 133 is located on both sides of the first gear 132 and meshes with the first gear 132. The first driving motor 131 drives the first gear 132 to rotate, and then the first gear 132 synchronously drives the second gears 133 on both sides. Then, the second gears 133 synchronously drive the screw rods 5 on both sides to rotate, facilitating the threaded sleeve to drive the movable frame 7 to move up and down, ensuring the synchronous movement of both sides of the movable frame 7.

[0027] L-shaped bolts 14 are fixed on the opposite sides of the mounting disc 2. Through holes are formed at both ends of the installation shaft 3. The L-shaped bolts 14 penetrate through the through holes and are threadedly connected with limit nuts 15. By the L-shaped bolts 14 penetrating through the through holes and connecting with the limit nuts 15, it is convenient to connect the installation shaft 3 with the mounting disc 2, and the rotation of the mounting disc 2 drives the installation shaft 3 to rotate.

[0028] A second drive motor 16 is fixed to the top of the processing box 1. The output shaft of the second drive motor 16 penetrates into the inner cavity of the processing box 1 and is drivingly connected to the mounting disc 2 at the top. By driving the mounting disc 2 to rotate with the second drive motor 16, the mounting shaft 3 drives the cone hub body 4 to rotate, and the horizontal brush cylinder 10 and the vertical brush cylinder 11 can be used to remove the burrs on the surface of the cone hub body 4.

[0029] Vertical grooves 17 are formed on the surface of the mounting shaft 3. A support spring 18 is fixed in the inner cavity of the vertical groove 17. The other side of the support spring 18 is fixed with a rack 19. The side of the rack 19 away from the support spring 18 penetrates through the vertical groove 17 and meshes with the teeth inside the cone hub body 4. The rack 19 is supported by the support spring 18, and the rack 19 penetrates through the vertical groove 17 to be clamped with the cone hub body 4, preventing the horizontal brush cylinder 10 and the vertical brush cylinder 11 from contacting the cone hub body 4 when the mounting shaft 3 drives the cone hub body 4, resulting in the cone hub sliding on the mounting shaft 3 and unable to perform all-round processing on the cone hub body 4.

[0030] Sliding grooves 20 are annularly formed at the top and bottom of the inner cavity of the processing box 1. Sliders 21 are slidably connected to the four sides of the inner cavity of the sliding groove 20. The opposite sides of the sliders 21 penetrate through the sliding groove 20 and are fixed to the surface of the mounting disc 2. By sliding the sliders 21 in the inner cavity of the sliding groove 20, it is convenient to limit the mounting disc 2 by the sliders 21 and prevent the mounting disc 2 from shaking and affecting the stability of the mounting shaft 3.

[0031] A third drive motor 22 is embedded on one side of the inner cavity of the through groove 8. The output shaft of the third drive motor 22 is fixedly connected to one end of the intermediate rotating shaft 9 of the horizontal brush cylinder 10. The third drive motor 22 can drive the horizontal brush cylinder 10 to rotate to remove the burrs inside the teeth on the surface of the cone hub body 4.

[0032] The radius of the horizontal brush cylinder 10 is smaller than the radius of the vertical brush cylinder 11. The front of the processing box 1 is hinged with a box door through a hinge. By setting the radii of the horizontal brush cylinder 10 and the vertical brush cylinder 11, it is convenient for the vertical brush cylinder 11 to contact the surface between the cone hub bodies 4, and then the horizontal brush cylinder 10 removes the burrs inside the outer teeth of the cone hub body 4.

[0033] During specific use, the cone hub body 4 is sleeved on the mounting shaft 3 in sequence from one end of the mounting shaft 3. Meanwhile, the rack 19 is engaged with the teeth inside the cone hub body 4 with the support of the support spring 18, facilitating the synchronous rotation of the cone hub body 4 driven by the mounting shaft 3. Then, the L-shaped bolt 14 is passed through the through hole and limited by the limit nut 15. The second drive motor 16 is started, and the second drive motor 16 drives the mounting plate 2 to rotate. Subsequently, the mounting plate drives the mounting shaft 3 to rotate through the L-shaped bolt 14. Then, the first drive motor 131 is started, and the first drive motor 131 drives the first gear 132 to drive the second gear 133. The second gear 133 drives the screw rod 5 to rotate. The screw rod 5 drives the fixed block 6 and the movable frame 7 to move through the threaded sleeve. Meanwhile, the third drive motor 22 drives the rotating shaft 9 and the transverse brush barrel 10 to rotate. During the up-and-down movement of the movable frame 7, the transverse brush barrel 10 and the vertical brush barrel 11 respectively remove burrs from different positions on the surface of the cone hub body 4, making the surface of the cone hub body 4 smooth.
