Description

Technical Field

[0001] This utility model belongs to the field of sandblasting tooling technology, and particularly relates to a sandblasting tooling for a gearbox gear ring. Background Technology

[0002] Sandblasting of gearbox gear rings requires strengthening and protecting key stress-bearing areas. The tooth surface and root transition zone need full-coverage sandblasting reinforcement. High-speed sandblasting impact generates a residual compressive stress layer, improving bending fatigue strength and contact fatigue life. Stress concentration is significant at the tooth root; sandblasting refines the surface grains and forms a work-hardened layer, improving resistance to crack propagation. During sandblasting, sandblasting fixtures are needed to protect the reference outer diameter and end face. Existing sandblasting fixtures are limited by their single-size design, making them unsuitable for gear rings of different thicknesses. Furthermore, existing sandblasting fixtures often rely on bolt installation, which is complex and cumbersome, and prone to wear and loss over time. Utility Model Content

[0003] This utility model addresses the problems of existing technologies, such as the limited range of sizes making it difficult to adapt to gear rings of different thicknesses and the complex and cumbersome installation and disassembly processes. The proposed technical solution is as follows: A gearbox gear ring sandblasting fixture includes a gear ring with protective covers abutting at both its upper and lower ends. An annular rubber ring is fixedly connected to one end of the protective cover away from the gear ring, and a locking pin is fixedly connected to one end of the annular rubber ring near the gear ring. The outer surface of the locking pin is slidably connected to the inner surface of the protective cover and the gear ring. A circular sleeve is slidably connected to the outer surface of the gear ring, and the outer surface of the circular sleeve is slidably connected to the inner surface of the annular rubber ring. An adjustment component is provided inside the circular sleeve, and several lifting rings are fixedly connected to the outer surface of the circular sleeve.

[0004] As a preferred embodiment of the above technical solution, the adjusting component includes a limiting column fixedly connected to the inner wall of the annular sleeve, a double-threaded rod rotatably connected to the end of the limiting column away from the gear ring, L-shaped guide blocks threadedly connected to the outer surfaces of both ends of the double-threaded rod, a lateral bevel gear rotatably connected to the inner surface of the annular sleeve, the outer surface of the lateral bevel gear meshing with the outer surface of the bevel gear ring, and a height adjustment knob fixedly connected to the end of the lateral bevel gear away from the gear ring.

[0005] As a preferred embodiment of the above technical solution, a reset spring rod is fixedly connected to one end of the upper part of the L-shaped guide block near the gear ring, and a slanted locking block is fixedly connected to the other end of the reset spring rod. A triangular notch is provided on the locking post, and the outer surface of the slanted locking block cooperates with the inner surface of the triangular notch. The outer surfaces of the L-shaped guide block and the slanted locking block are slidably connected to the inner surface of the circular ring sleeve.

[0006] As a preferred embodiment of the above technical solution, a square ring is slidably connected to the outer surface of the limiting column, a telescopic rod is fixedly connected to one end of the square ring near the toothed ring, a Z-shaped linkage arm is fixedly connected to the other end of the telescopic rod, a linkage rod is rotatably connected to the other end of the Z-shaped linkage arm, the left inner surface of the linkage rod is rotatably connected to the inner surface of the L-shaped guide block, the other end of the linkage rod is fixedly connected to the shock absorber, and the other end of the shock absorber is rotatably connected to the end of the inclined block away from the toothed ring.

[0007] As a preferred embodiment of the above technical solution, an opening and closing baffle is slidably connected to one side of the limiting column. The opening and closing baffle is located at the outer end of the square ring. A threaded rod is threadedly connected to the inner surface of the opening and closing baffle. The outer surface of the threaded rod is rotatably connected to the inner surface of the square ring and the circular ring sleeve.

A limiting knob is fixedly connected to the end of the threaded rod away from the toothed ring.

[0009] The beneficial effects of this utility model are as follows: When installing the annular rubber ring, the inclined surface of the inclined block abuts against the bottom surface of the locking post. The inclined block will retract and move to the triangular notch on the locking post. Under the elastic force of the reset spring rod, the inclined block will engage with the locking post, thus limiting the locking post and the annular rubber ring. Turning the height adjustment knob, through the meshing transmission of the lateral bevel gear and bevel gear ring and the reverse setting of the threads at both ends of the double-headed threaded rod, can drive the upper and lower L-shaped guide blocks to move synchronously, thereby adapting to gear rings of different thicknesses and improving the overall practicality and adaptability. Under the limiting action of the L-shaped guide block on the linkage rod and the linkage formed by the square ring, telescopic rod, Z-shaped linkage arm, linkage rod and shock absorber, when the square ring slides back and forth, it can drive the inclined locking block to move in the opposite direction. Turning the opening and closing knob, through the threaded transmission between the threaded rod one and the opening and closing baffle and the limiting column limiting the opening and closing baffle, can drive the opening and closing baffle to abut against the square ring and move towards the gear ring, thereby driving the inclined locking block to retract, releasing the inclined locking block from limiting the locking column, improving the efficiency of disassembly and installation, and improving the overall practicality. Turning the limiting knob, through the threaded transmission between the threaded rod two and the limiting baffle and the limiting column limiting the limiting baffle, can drive the limiting baffle to abut against the square ring, thereby further limiting the inclined locking block after completing the limiting of the locking column, avoiding the situation where the inclined locking block retracts due to impact, improving the overall stability and practicality.

When installing the annular rubber ring 3, the inclined surface of the inclined block 508 abuts against the bottom surface of the retaining post 31. Then, the inclined locking block 508 will retract and move to the triangular notch on the locking post 31. Under the elastic reset action of the reset spring rod 507, the inclined locking block 508 will engage with the locking post 31, thus completing the limiting of the locking post 31 and the annular rubber ring 3.
