[0020] In the description of the present utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0021] Please refer to Figure 1 、 Figure 2 The present utility model provides a portable chamfering auxiliary tooling for gear parts, including a base 01, a rotating shaft 02, a rotating assembly 03, and a braking assembly 04; a seat body 11 is arranged on the base 01. The rotating shaft 02 is longitudinally arranged on the seat body 11. The rotating assembly 03 is rotatably arranged at the upper end of the rotating shaft 02 and is used for placing the workpiece to be processed. The braking assembly 04 is arranged on the seat body 11. When the braking assembly 04 is pressed, the upper end of the braking assembly 04 will be separated from the bottom of the rotating assembly 03, and the rotating assembly 03 can rotate circumferentially along the rotating shaft 02. When the braking assembly 04 is released, the upper end of the braking assembly 04 will be in contact with and fit against the bottom of the rotating assembly 03 to form braking on the rotating assembly 03. When in use, by fixing the gear part to be processed on the rotating assembly 03, when the braking assembly 04 is released, the upper end of the braking assembly 04 will be in contact with and fit against the bottom of the rotating assembly 03, which can limit the circumferential rotation of the rotating assembly 03. At this time, the operator can sit on a bench and chamfer the gear part to be processed; and when it is necessary to rotate the gear part, the braking assembly 04 can be pressed, the upper end of the braking assembly 04 will be separated from the bottom of the rotating assembly 03, and then the rotating assembly 03 can be rotated, so that the rotating assembly 03 drives the gear part to be processed to rotate circumferentially, facilitating adjustment to the next processing position. During the entire chamfering process, the operator only needs to sit on a bench to operate, which is not only flexible in operation, but also reduces the chamfering work intensity and ensures the processing efficiency.

[0022] In one embodiment, the braking assembly 04 includes a guide cylinder 41, a spring 42, and a column 43. The column 43 is disposed on the base 01. The guide cylinder 41 is sleeved outside the column 43. The spring 42 is disposed inside the guide cylinder 41. The upper end of the spring 42 is connected to the upper end inside the guide cylinder 41. The lower end of the spring 42 is sleeved on the column 43. When pressing the guide cylinder 41, the guide cylinder 41 will compress the spring 42, causing the upper end of the guide cylinder 41 to disengage from the bottom of the rotating assembly 03, and then the rotating assembly 03 can be rotated to adjust the machining position of the gear part to be machined. When the guide cylinder 41 is released, the upper end of the guide cylinder 41 will abut and fit against the bottom of the rotating assembly 03, thereby forming a pressing force on the bottom of the rotating assembly 03 by the upper end of the guide cylinder 41 to limit the rotation of the rotating assembly 03, so as to facilitate the chamfering operation of the gear part to be machined.

[0023] Specifically, a protrusion 05 is provided on the outer wall of the guide cylinder 41 to facilitate pressing down the guide cylinder 41.

[0024] Specifically, a resistance block 06 is provided at the upper end of the guide cylinder 41. Through the resistance block 06, a pressing force can be formed on the bottom of the rotating assembly 03, and the friction can be increased, so as to better limit the rotation of the rotating assembly 03.

[0025] Specifically, for facilitating the operation and control of the guide cylinder 41, a foot pedal 07 for pressing the protrusion 05 is provided on one side of the column 43 on the base 01. The operator only needs to sit on the bench and can use his foot to manipulate the lifting or lowering of the guide cylinder 41, thereby realizing the circumferential rotation control of the rotating assembly 03.

[0026] In one embodiment, the rotating assembly 03 includes an end cover 31, a pressure plate 32, and a bearing cup 33. The bearing cup 33 is mounted on the rotating shaft 02 through a bearing. The end cover 31 is fixed to the upper end of the bearing cup 33. The pressure plate 32 is fixed to the lower end of the bearing cup 33. For facilitating disassembly and assembly, both the end cover 31 and the pressure plate 32 are fixed to the bearing cup 33 by screws. To prevent scratching the gear part to be machined, a rubber pad is further provided on the end cover 31.

[0027] Among them, a round hole through which the rotating shaft 02 can pass is provided on the end cover 31.

[0028] Among them, a through hole through which the rotating shaft 02 can pass is provided on the pressure plate 32.

[0029] In one embodiment, the height of the rotating shaft 02 can be adjusted, so as to facilitate adjusting the height of the entire device according to the height of the operator, so that the gear part to be machined can be at a better machining height, facilitating the operator to chamfer.

[0030] Specifically, the lower part of the rotating shaft 02 is threadedly connected to the seat body 11. When adjusting the height of the rotating shaft 02, it can be achieved by adjusting the length of the rotating shaft 02 screwed into the seat body 11.

[0031] To prevent the rotating shaft 02 from rotating after the height is adjusted, a positioning pin is provided in the radial direction of the side part of the seat body. The positioning pin can be inserted into the interior of the seat body and is threadedly connected to the seat body 11 to restrict the rotation of the rotating shaft 02.
