[0001] The utility model relates to the technical field of gear processing, and particularly relates to a positioning device for machining a bevel oil hole of a gear. Background Technique

[0002] The drilling position of the bevel oil hole of a gear is usually at a specific part of the gear. The oil hole may be located in the hub part of the gear, in the same plane as the gear axis and at a certain inclination angle, which can ensure that the lubricant can smoothly flow into the gear interior to effectively lubricate and cool the gear. The bevel oil hole may also be directly drilled on the tooth surface of the gear, but this is usually not the mainstream design. The drilling position of the bevel oil hole of a gear is usually on the hub of the gear. A positioning device for machining a bevel oil hole of a gear has important application value in the field of gear processing. The purpose of a positioning device for machining a bevel oil hole of a gear is to improve the machining accuracy and efficiency of the bevel oil hole of the gear;

[0003] After retrieval, the utility model with the publication number of CN221088122U discloses a positioning device for machining a bevel oil hole of a gear. Although this utility model patent solves the problem of positioning the gear when machining the bevel oil hole, since the positioning state of the gear is an inclined state, the positioning steps of using a general positioning device in the prior art are complex, time-consuming, and the efficiency is relatively low; however, this utility model patent has the following problems:

[0004] First, due to the different sizes of gears, this utility model patent cannot fix gears of different sizes according to actual needs, and there are certain limitations in the use process;

[0005] Second, since the angle of the bevel oil hole is calculated according to actual needs, the required angles of the bevel oil holes of gears are different, and this utility model patent cannot adjust the gear angle according to requirements;

[0006] Therefore, a positioning device for machining a bevel oil hole of a gear is proposed. Utility Model Content

[0007] In view of this, the utility model provides a positioning device for machining a bevel oil hole of a gear to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0025] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0026] As Figures 1-4 shown, the embodiment of the present utility model provides a gear inclined oil hole machining positioning device: including a support table 1, a semi-worm gear 2 is fixedly connected to the upper surface of the support table 1, hinge rods 3 are fixedly connected to both sides of the semi-worm gear 2, a support rod 4 is hinged to the outer wall of the hinge rod 3, a drilling workbench 5 is fixedly connected to the upper surface of the support rod 4, a gear to be drilled 6 is arranged on the upper surface of the drilling workbench 5, a connecting block 7 is fixedly connected to the lower surface of the drilling workbench 5, a limiting ring 8 is fixedly connected to the bottom of the connecting block 7, a support short rod 9 is rotatably connected inside the limiting ring 8, a worm 10 is fixedly connected to one end of the support short rod 9, and the worm 10 is meshed with the semi-worm gear 2.

[0027] In one embodiment, a threaded rod 11 is fixedly connected to the upper surface of the support table 1, a hinge seat one 12 is fixedly connected to the outer wall of the threaded rod 11, a connecting rod one 13 is hinged inside the hinge seat one 12, one end of the connecting rod one 13 far from the hinge seat one 12 is hinged to a hinge seat two 14, a connecting rod two 15 is hinged inside the hinge seat two 14, one end of the connecting rod two 15 is hinged to a hinge seat three 16, an auxiliary ring 17 is fixedly connected to the side of the hinge seat three 16 close to the threaded rod 11, the auxiliary ring 17 is slidably connected to the outer wall of the threaded rod 11, and an adjusting ring 18 is connected above the auxiliary ring 17, and the adjusting ring 18 is threadedly connected to the outer wall of the threaded rod 11.

[0028] In one embodiment, there are two sets of the connecting block 7, the limiting ring 8 and the support short rod 9, and the worm 10 is located between the two sets of the connecting block 7, the limiting ring 8 and the support short rod 9. The two sets of the connecting block 7, the limiting ring 8 and the support short rod 9 support the worm 10 more stably. There are multiple sets of the hinge seat one 12, the connecting rod one 13 and the hinge seat two 14, and the multiple sets of the hinge seat one 12, the connecting rod one 13 and the hinge seat two 14 are evenly distributed. The multiple sets of the connecting rod one 13 and the hinge seat two 14 fix the gear to be drilled 6, so that the gear to be drilled 6 is stressed evenly and the gear to be drilled 6 is prevented from deforming. An adjusting handle 19 is fixedly connected to the end of the support short rod 9 far from the worm 10. The adjusting handle 19 facilitates the staff to rotate the worm 10, thereby adjusting the angle of the gear to be drilled 6.

The connecting rod 13, the hinge seat 14 and the connecting rod 15 change their angles with the movement of the auxiliary ring 17. Then rotate the adjusting ring 18. Since the adjusting ring 18 is threadedly connected to the threaded rod 11, the adjusting ring 18 moves up and down along the outer wall of the threaded rod 11, so as to squeeze the auxiliary ring 17 downward through the adjusting ring 18. When the connecting rod 13 or the hinge seat 14 is in close contact with the gear 6 to be drilled, the fixing of the gear 6 to be drilled is completed, so that gears of different sizes can be fixed according to actual needs, and the application range is wider; when it is necessary to adjust the angle of the gear 6 to be drilled, the staff manually rotates the adjusting handle 19, and the rotation of the adjusting handle 19 drives the supporting short rod 9 and the worm 10 to rotate. Since the worm 10 is meshed with the half worm gear 2 and the half worm gear 2 is fixed, the worm 10 changes its angle along the outer wall of the half worm gear 2 under the cooperation of the support rod 4 and the hinge rod 3, so as to adjust the angle of the gear 6 to be drilled according to actual needs.
