Description

Technical Field

[0001] This utility model belongs to the field of wind power gearbox processing technology, and more specifically, it relates to a multi-mode drilling device. Background Technology

[0002] As the core transmission component of wind turbine generator sets, the wind turbine gearbox plays a crucial role in converting the low-speed power of the wind turbine into the high-speed power of the generator. Its structural strength, precision, and reliability directly affect the overall operating efficiency and lifespan of the unit. Since wind power equipment operates in harsh environments such as high altitude, windy sandstorms, and large temperature differences, the gearbox must withstand huge alternating loads and impacts. Therefore, extremely high requirements are placed on the processing precision and structural integrity of its components.

[0003] Application number CN202221021133.3 discloses a drilling device for adjusting rings in wind turbine gearboxes, comprising a base plate, a load-bearing plate connected to the top of the base plate, uprights connected to the top surfaces of the base plate on all four sides of the load-bearing plate, annular plates connected to the top of the uprights, annular grooves formed at the bottom of the annular plates, four cylinders connected to the top surfaces of the annular plates above the four uprights, pressure blocks connected to the output ends of the cylinders, and annular gears connected to the outer side of the annular plates. A first motor is provided on one side of the annular gears and connected to the base plate. This invention uses the rotation of the first motor output to drive the spur gear to rotate, which in turn drives the annular plate to rotate, thereby changing the position of the adjusting ring body. The entire drilling process of the adjusting ring body can be completed without repeatedly clamping and fixing it, saving time and effort and increasing drilling efficiency.

[0004] Based on the above patent search and understanding of the application of existing drilling equipment:

[0005] Existing drilling equipment is inconvenient to adjust angle, making it difficult to meet the drilling requirements of workpieces at different angles. For workpieces that require drilling at multiple angles, it is often necessary to disassemble and re-clamp them multiple times, which is not only cumbersome to operate, but also affects the machining accuracy.

[0006] The drilling position adjustment is not flexible enough, and the movement adjustment in the front-back and up-down directions is not precise and convenient enough, resulting in low drilling efficiency and an inability to quickly adapt to workpieces of different sizes and drilling position requirements. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a multi-mode drilling device to solve the issues of inconvenient angle adjustment in existing drilling devices, which makes it difficult to meet the drilling requirements of workpieces at different angles. For workpieces requiring multi-angle drilling, multiple disassembly and re-clamping are often necessary, which is not only cumbersome but also affects the processing accuracy and drilling position adjustment flexibility. The movement adjustment in the front-back and up-down directions is not precise and convenient enough, resulting in low drilling efficiency and an inability to quickly adapt to workpieces of different sizes and drilling position requirements.

[0008] The technical solution adopted in this utility model is as follows:

A drilling machine is fixedly installed below the front end of the lifting component, and the drilling machine is located directly above and behind the chuck clamp.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By setting an angle plate on the top of the limit frame, and cooperating with motor A to drive the chuck fixture to rotate, the guide seat under the front end of the chuck fixture can cooperate with the angle plate to accurately control the rotation angle of the workpiece, realizing multi-angle drilling of the workpiece without the need for multiple disassembly and clamping, thus improving processing accuracy and efficiency.

[0017] By using motor B to drive the advancing component to slide within the advancing frame, the position of the drilling machine in the front-to-back direction can be precisely adjusted; by using motor C to drive the lifting component to slide within the lifting frame, the position of the drilling machine in the up-down direction can be precisely controlled, greatly improving the flexibility and accuracy of drilling position adjustment, and adapting to workpieces of different sizes and drilling position requirements.

[0018] The chuck clamps hold the workpiece firmly and stably, effectively preventing workpiece wobbling during drilling, ensuring drilling quality, and reducing the risk of workpiece damage. Attached Figure Description
