Description

Technical Field

[0001] This utility model relates to the field of hardware parts processing technology, specifically a hardware parts drilling device with automatic clamping function. Background Technology

[0002] Hardware parts, also known as small hardware or hardware accessories, refer to various metal utensils made from metals such as iron, steel, and aluminum through physical processing such as forging, rolling, and cutting. Hardware parts include mold hardware parts, mechanical hardware parts, daily-use hardware parts, shop window hardware parts, marine hardware parts, building hardware parts, aerospace hardware parts, and security products. Most small hardware products are not final consumer goods, but rather supporting products, semi-finished products, and tools used in the production process of industrial manufacturing. Only a small portion of daily-use hardware products are essential tools for people's daily lives.

[0003] Current hardware parts drilling devices require workers to manually clamp the workpiece during operation. This method not only increases the labor intensity of workers but also easily leads to slippage or displacement of the workpiece during drilling, resulting in quality problems such as inaccurate drilling position and irregular hole shape. In addition, manual clamping is also affected by various factors such as worker skill level and fatigue, further increasing the risk of processing errors. Therefore, we propose a hardware parts drilling device with automatic clamping function to solve the above problems. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a hardware parts drilling device with automatic clamping function, which has the following beneficial effects:

[0016] This invention utilizes a drive motor to rotate a first gear via a second gear. The first gear then rotates a lead screw, which in turn moves a moving plate. The moving plate, via a vertical rod, causes ball bearings to contact and press against a corresponding trapezoidal block. Under this pressure, the trapezoidal block moves a corresponding L-shaped block. The L-shaped block slides on a guide rod and stretches a spring, which in turn moves a corresponding clamping plate. The two clamping plates then hold and fix the workpiece, automatically clamping it to prevent slippage and inaccurate drilling, while also reducing the workload for workers.
