Description

Technical Field

[0001] This utility model belongs to the technical field of gear processing positioning equipment, specifically relating to an angular positioning device. Background Technology

[0002] In the machining process of axle gears, angular positioning of the axle gears is frequently required. For example, when machining the back cone side of an axle gear, angular positioning is necessary. A common positioning structure includes a base with a receiving cavity containing multiple steel balls arranged circumferentially. When positioning the axle gear, the top cone side of the axle gear is inserted into the receiving cavity, and the steel balls engage between adjacent teeth, achieving circumferential positioning. The limitation of this common positioning structure is that the steel balls are welded to the base. To accommodate different axle gears, the steel balls need to be re-welded to the base, resulting in poor adaptability and low efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an angular positioning device that is applicable to various half-shaft gears.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows: This application provides an angular positioning device for angular positioning of a half-shaft gear, comprising a base, multiple sliding parts, and abutting parts.

The abutting parts are adjustablely connected to the sliding parts, and the end of the abutting part near the axis of the receiving cavity is a spherical end.

[0005] In some embodiments, the surface of the sliding part that abuts against the peripheral wall of the receiving cavity is an arc surface.

[0006] In some embodiments, the sliding portion has a fan-shaped structure.

[0007] In some embodiments, a threaded hole is provided on the side of the sliding part near the axis of the receiving cavity, and the abutment part is threadedly connected to the threaded hole.

[0008] In some embodiments, the side of the sliding portion near the axis of the receiving cavity is an outwardly convex arc surface facing the peripheral wall of the receiving cavity.

[0009] In some embodiments, a cover plate is also included, with an opening provided on one side of the receiving cavity along the axial direction of the cavity, the cover plate covering the opening, and the cover plate having an inlet and outlet.

[0010] In some embodiments, the cover plate is bolted to the base.

[0011] In some embodiments, the cover plate is provided with a connecting through hole, the diameter of the end of the connecting through hole away from the receiving cavity is larger than the diameter of the end closer to the receiving cavity.

[0012] This utility model has the following beneficial effects:

[0013] 1.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

Therefore, they should not be construed as limitations on this utility model.

[0023] This application provides an angular positioning device for angular positioning of a half-shaft gear 1, including a base 3, multiple sliding parts 6, and abutting parts 7. The base 3 is provided with a cylindrical receiving cavity 4, in which the multiple sliding parts 6 are received and abut against the peripheral wall of the receiving cavity 4. The abutting parts 7 are adjustablely connected to the sliding parts 6, and the end of the abutting part 7 near the axis of the receiving cavity 4 is a spherical end.

[0024] Angular positioning refers to circumferential positioning of the half-shaft gear 1.

[0025] The sliding part 6 abuts against the peripheral wall of the receiving cavity 4, allowing it to move circumferentially. This enables the positions of multiple sliding parts 6 to be adjusted as needed in the circumferential direction of the receiving cavity 4, and consequently, the position of the abutting part 7 connected to the sliding part 6 can also be adjusted as needed, allowing the abutting part 7 to adapt to different types of half-shaft gears 1, thus increasing the adaptability of the device.

[0026] Multiple abutment parts 7 are used to abut against the half-shaft gear 1. The multiple abutment parts 7 form multiple support points around the circumference of the half-shaft gear 1. When the half-shaft gear 1 is inserted into the receiving cavity 4, the half-shaft gear 1 can be supported by the abutment parts 7. The abutment parts 7 are provided between the teeth of the half-shaft gear 1, so that the half-shaft gear 1 can be positioned circumferentially by the abutment parts 7.

[0027] The spherical end of the abutment part 7 refers to the end of the abutment part 7 being hemispherical, which facilitates the abutment part 7 being inserted between the teeth of the half-shaft gear 1.

[0028] The abutment 7 is adjustablely connected to the sliding part 6. By adjusting the position of the abutment 7 relative to the sliding part 6, the abutment 7 can adapt to different types of half-shaft gears 1, thus increasing the adaptability of the device.

[0029] In this embodiment, the longitudinal direction of the abutment 7 can extend radially along the receiving cavity 4, and the abutment 7 can be movably connected to the sliding part 6 radially along the receiving cavity 4. That is, the position of the abutment 7 relative to the sliding part 6 is adjustable in the radial direction of the receiving cavity 4, so that the abutment 7 can adapt to different types of half-shaft gears 1, increasing the adaptability of this device.

[0030] This device can be used alone or in conjunction with other fixing devices. For example, after the half-shaft gear 1 is positioned by the angular positioning device, the pressure device applies pressure to the half-shaft gear 1, pressing it against the base 3, so that the half-shaft gear 1 can be fixed and cannot be displaced.

[0031] In some embodiments, the surface of the sliding part 6 that abuts against the periphery of the receiving cavity 4 is an arc surface.

[0032] The arc surface of the sliding part 6 is designed to fit the peripheral wall of the receiving cavity 4, that is, the arc surface of the sliding part 6 can fit against the peripheral wall of the receiving cavity 4.

[0033] The surface of the sliding part 6 that abuts against the peripheral wall of the receiving cavity 4 is an arc surface. On the one hand, this increases the contact area between the sliding part 6 and the peripheral wall of the receiving cavity 4, thereby increasing the movement accuracy of the sliding part 6 relative to the base 3. On the other hand, it ensures that when the sliding part 6 moves along the peripheral wall of the receiving cavity 4, the abutting part 7 can always face the axis of the receiving cavity 4.

[0034] In some embodiments, the sliding portion 6 has a fan-shaped structure.

[0035] The sliding part 6 is fan-shaped. On the one hand, this allows the volume of the side of the sliding part 6 that abuts against the peripheral wall of the receiving cavity 4 to be larger, which in turn allows for a larger arc surface area of ​​the sliding part 6, improving the movement accuracy of the sliding part 6 and the receiving cavity. On the other hand, this allows the volume of the side of the sliding part 6 that is closer to the axis of the receiving cavity 4 to be smaller, thus reducing the space occupied by the sliding part 6 and lowering the risk that an excessively large sliding part 6 would obstruct the insertion of the half-shaft gear 1 into the receiving cavity 4.

[0036] In some embodiments, the sliding part 6 is provided with a threaded hole 8 on the side near the axis of the receiving cavity 4, and the abutment part 7 is threadedly connected to the threaded hole 8.

[0037] The axial direction of the threaded hole 8 can extend radially along the receiving cavity 4.

[0038] The abutment 7 is threaded to the threaded hole 8, so that the position of the abutment 7 relative to the sliding part 6 can be adjusted by rotating the abutment 7.

[0039] In this embodiment, the spherical end of the abutment part 7 allows it to engage normally with the half-shaft gear 1 after rotating at any angle.

[0040] In some embodiments, the side of the sliding portion 6 near the axis of the receiving cavity 4 is an outwardly convex arc surface facing the peripheral wall of the receiving cavity 4.

[0041] The advantage of this design is that, on the one hand, it reduces the size of the sliding part 6 extending along the axis of the receiving cavity 4, thereby reducing the risk that the sliding part 6 is too large and obstructs the insertion of the half-shaft gear 1 into the receiving cavity 4.

[0042] In some embodiments, a cover plate 2 is also included. An opening is provided on one side of the receiving cavity 4 along the axial direction of the receiving cavity 4, and the cover plate 2 covers the opening. The cover plate 2 is provided with an inlet and outlet.

[0043] The opening of the receiving cavity 4 allows the half-shaft gear 1 to be inserted into the receiving cavity 4 and engage with the abutment part 7.

[0044] The inlet and outlet of the cover plate 2 allow the receiving cavity 4 to still communicate with the outside even after the cover plate 2 is placed over the opening.

[0045] The cover plate 2 can be a hollow annular structure.

[0046] After the cover plate 2 is placed over the opening, it can limit the sliding part 6 and reduce the risk of the sliding part 6 falling out of the receiving cavity 4.

[0047] In some embodiments, the cover plate 2 is bolted to the base 3.

[0048] The advantages of this design are twofold: firstly, it improves the reliability of the connection between the cover plate 2 and the base 3; secondly, when the cover plate 2 is positioned over the opening, it can contact the sliding part 6. By adjusting the tightness of the bolts, the pressure exerted by the cover plate 2 on the sliding part 6 can be adjusted. When the bolts are tightened, the pressure of the cover plate 2 on the sliding part 6 increases, locking the sliding part 6. Conversely, when the bolts are loosened, the pressure of the cover plate 2 on the sliding part 6 decreases, allowing the position of the sliding part 6 to be adjusted.

[0049] In some embodiments, the cover plate 2 is provided with a connecting through hole 5, the diameter of the connecting through hole 5 at the end away from the receiving cavity 4 is larger than the diameter of the end close to the receiving cavity 4.

[0050] The connecting through hole 5 allows bolts to pass through, meaning that after passing through the connecting through hole 5, the bolts are threaded into the base 3.

[0051] The diameter of the connecting through hole 5 at the end away from the receiving cavity 4 is larger than the diameter of the end near the receiving cavity 4, so that the connecting through hole 5 can form a countersunk hole in the cover plate 2. The countersunk hole can be used to accommodate the head of the bolt, so that the bolt will not protrude from the surface of the cover plate 2, reducing the risk that the bolt will obstruct the positioning of the half shaft gear 1.

[0052] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
