[0002] In gear manufacturing, end face drilling is a critical machining process, as its precision directly affects the gear's assembly performance and transmission reliability, especially in applications such as vehicle drive axles, differentials, and reducers. Currently, gear end face drilling requires the use of clamps for clamping and positioning. However, ordinary clamps have limited axial and radial constraint forces on the gear. During drilling, the cutting forces on the gear can easily cause the drilling position to shift, resulting in hole deviations or even gear damage, affecting the gear machining quality. After drilling, the clamps must be fully opened to remove the gear, leading to shortcomings in its usability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a gear machining end face drilling positioning fixture. One side is provided with an arc-shaped plate for gear drilling positioning. The arc-shaped plate is designed to be lifted. When raised, it can be used to limit the gear during drilling. When lowered, it can facilitate the quick removal of the gear from the worktable, thereby improving the gear machining efficiency. The other side is a movable positioning seat. The positioning seat is positioned by meshing with the gear through the teeth on its side, reducing the displacement of the gear during drilling. At the same time, it can also be pressed and positioned during gear drilling to ensure the stability of the gear during drilling. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gear machining end face drilling positioning fixture, including a material table, a support frame for supporting and positioning the material table is installed on the lower side of the material table, a worktable is provided in the middle of the material table, several sets of arc plates are symmetrically arranged on one side of the worktable, and the several sets of arc plates are liftable, a positioning seat is slidably installed on the other side of the worktable, several locking teeth are fixed on the side of the positioning seat facing the arc plates, a driving component for pushing the positioning seat to move back and forth is installed on the side of the material table, a liftable limiting plate is provided above the positioning seat, and a clamping plate located in front of the positioning seat is fixed on the lower side of the limiting plate.

[0005] As a preferred embodiment of this utility model, the material platform has several connecting openings on its side, the arc-shaped plate is slidably disposed in the connecting openings, the support frame is fixed with a positioning frame on its side, the positioning frame is equipped with an electric telescopic rod on its side, and a connecting plate is fixed at the telescopic end of the electric telescopic rod. The connecting plate is used to connect and fix several arc-shaped plates.

The driving assembly includes a first electric push rod installed on the lower side of the workbench, and the telescopic end of the first electric push rod is connected and fixed to the side of the positioning plate.

[0007] As a preferred embodiment of this utility model, a positioning rod is fixed to the side of the workbench, and the positioning plate is slidably connected to the positioning rod.

[0008] As a preferred embodiment of this utility model, a guide rod is fixed on the upper side of the positioning seat, the limiting plate is slidably disposed on the guide rod, and a second electric push rod is installed on the side of the limiting plate, the telescopic end of the second electric push rod being connected and fixed to the side of the positioning seat.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. The gear machining end face drilling positioning fixture of this utility model sets the gear between two sets of arc plates during drilling. Then, the drive component is controlled to move the positioning seat, so that the cleats on the side of the positioning seat contact or mesh with the gear. The two sets of arc plates and the positioning seat clamp the gear to the outside for positioning. The cleats improve the positioning effect and reduce gear movement during drilling. This positioning fixture can be used for positioning when drilling various types of gears. By adjusting the moving distance of the positioning seat driven by the drive component, different types of gears can be accommodated and fixed between the two sets of arc plates and the positioning seat, which meets the clamping and positioning requirements when drilling various types of gears.

[0010] 2. The gear machining end face drilling positioning fixture of this utility model, after drilling is completed, drives the positioning seat to move and reset through the drive assembly. At the same time, the electric telescopic rod controls the connecting plate to drive the two sets of arc plates to descend synchronously. When the arc plate moves down in the connecting port and is flush with the surface of the worktable, the gear can be directly slid away from the worktable, improving the gear picking and placing efficiency. After the arc plate is raised, it can be used for repositioning when drilling gears, which facilitates the use of this positioning fixture.

[0011] 3. In the gear machining end face drilling positioning fixture of this utility model example, when the gear is clamped by the two sets of arc plates and positioning seats before drilling, the second electric push rod is controlled to drive the limiting plate to move down, so that the clamping plate fits against the gear and presses it on the worktable, which further improves the stability of gear drilling. When the second electric push rod drives the limiting plate to move down, the guide rod plays a limiting and guiding role on the limiting plate, ensuring the stability of the limiting plate when it moves.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a gear machining end face drilling positioning fixture, including a material table 1, a support frame 2 for supporting and positioning the material table 1, and a worktable 3 in the middle of the material table 1. The material table 1 is used for placing the gear before and after drilling. The drilling equipment can be installed on the material table 1 for use or the material table 1 can be placed directly below the drilling device for use. It should be noted that the drilling device adopts the existing technology, and during the drilling process, it can be adjusted and moved forward, backward, left, and right according to the drilling position, as well as the feed and lifting of the tool.

[0016] Several sets of arc-shaped plates 4 are symmetrically arranged on one side of the workbench 3. The sets of arc-shaped plates 4 are liftable. Preferably, two sets of arc-shaped plates 4 are symmetrically arranged. A positioning seat 8 is slidably installed on the other side of the workbench 3. Several locking teeth 9 are fixed on the side of the positioning seat 8 facing the arc-shaped plates 4. A drive assembly is installed on the side of the material table 1 to push the positioning seat 8 to move back and forth. When drilling, the gear is placed between the two sets of arc-shaped plates 4. Then, the drive assembly is controlled to drive the positioning seat 8 to move, so that the locking teeth on the side of the positioning seat 8 contact or mesh with the gear. The two sets of arc-shaped plates 4 and the positioning seat 8 clamp the gear to the outside for positioning. The locking teeth 9 improve the positioning effect and reduce the movement of the gear during drilling. This positioning fixture can be used for positioning when drilling various types of gears. By adjusting the moving distance of the positioning seat 8 driven by the drive assembly, different types of gears can be accommodated and fixed between the two sets of arc-shaped plates 4 and the positioning seat 8, which meets the clamping and positioning needs when drilling various types of gears.

[0017] The material platform 1 has several connecting ports on its side. The arc plate 4 is slidably set in the connecting ports. The support frame 2 has a positioning frame 7 fixed on its side. The positioning frame 7 has an electric telescopic rod 6 installed on its side. The telescopic end of the electric telescopic rod 6 is fixed with a connecting plate 5. The connecting plate 5 is used to connect and fix several arc plates 4. After drilling is completed, the positioning seat 8 is moved and reset by the drive assembly. At the same time, the electric telescopic rod 6 controls the connecting plate 5 to drive the two sets of arc plates 4 to descend synchronously. When the arc plate 4 moves down in the connecting port and is flush with the surface of the worktable 3, the gear can be directly slid away from the worktable 3 to improve the gear picking and putting efficiency. After the arc plate 4 is raised, it can be used for repositioning when drilling gears, which facilitates the use of this positioning fixture.

[0018] The workbench 3 has an installation opening on its side along its radial direction. The positioning seat 8 is slidably disposed in the installation opening. The positioning plate 10, which is connected and fixed to the positioning seat 8, is installed on the lower side of the workbench 3 through the installation opening.
