Description

Technical Field

[0001] This utility model relates to the field of pearl drilling and processing technology, specifically a pearl drilling positioning and clamping mechanism. Background Technology

[0002] With the continuous development of the jewelry industry and the improvement of production automation, the operational processes in jewelry manufacturing are gradually transforming towards intelligence and automation. In the jewelry production process, pearl drilling, positioning, and clamping are among the key steps. Traditional pearl drilling, positioning, and clamping mechanisms typically rely on manual operation or semi-automated equipment. These traditional clamping mechanisms have many problems, affecting production efficiency and product quality.

[0003] Traditional pearl drilling and positioning typically relies on manual operation by workers, requiring them to manually adjust the pearl's position and clamp it. However, manual operation is not only time-consuming and labor-intensive, but also susceptible to human factors, causing positioning errors, unstable clamping, and other problems, which in turn affect the accuracy and quality of the drilling.

[0004] Existing clamping mechanisms often fail to achieve fully automated clamping, and many clamping processes still require manual assistance, resulting in limited production efficiency. The time spent on manual adjustment and clamping cannot meet the high-efficiency demands of jewelry production, especially in mass production, where clamping equipment with low levels of automation is particularly unsuitable.

[0005] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a pearl drilling positioning and clamping mechanism. Utility Model Content

[0010] The sliding mechanism includes a sliding sleeve and a sliding rod, wherein the sliding sleeve is fixed on the lifting seat and the sliding rod is slidably engaged with the sliding sleeve;

[0011] The clamp base is fixedly connected to the lifting base;

[0012] The clamping assembly includes a clamping cylinder, a pusher, a clamping arm positioning seat, a clamping arm, and a clamping block. The clamping cylinder is mounted on the clamping seat and drives the pusher. The clamping arm positioning seat is fixed on both sides of the clamping seat. The clamping arm is rotatably connected to the clamping arm positioning seat via a pivot. The pusher is hinged to the clamping arm via a pusher connecting part. The clamping block is fixed to the end of the clamping arm and is used to clamp pearls.

[0013] As a preferred technical solution, the slide rod extends vertically, and a linear guide rail structure is provided between the slide sleeve and the slide rod.

[0014] As a preferred technical solution, the clamping arms are arranged in two symmetrical sets, and each set of clamping arms has a clamping block at the end, and the inner side of the clamping block is provided with anti-slip texture.

[0015] As a preferred technical solution, the clamping base is equipped with a position sensor for detecting the clamping status of the clamping block.

[0016] As a preferred technical solution, the electric cylinder is driven by a servo motor, which can precisely control the lifting stroke and speed of the lifting seat.

[0017] As a preferred technical solution, the clamp cylinder is a double-acting cylinder, and its extension and retraction are controlled by a solenoid valve.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention relates to a pearl drilling and positioning clamping mechanism. The included lifting and sliding mechanisms automatically adjust the pearl's drilling position for precise positioning. An electric cylinder drives the lifting seat to move up and down, and the sliding cooperation of the sliding sleeve and rod allows for stable and accurate adjustment of the pearl's height and horizontal position. The double-acting cylinder's clamping cylinder, controlled by a solenoid valve, enables rapid switching between clamping and releasing, further improving production efficiency.

[0025] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a technical solution for a pearl drilling, positioning, and clamping mechanism: it includes a mounting base 1 on which a lifting mechanism is mounted. The lifting mechanism includes an electric cylinder 21 and a lifting seat 22 driven by the electric cylinder 21. The electric cylinder 21 is driven by a servo motor, which can precisely control the lifting stroke and speed of the lifting seat 22, thereby achieving precise positioning of the pearl.

[0027] The sliding mechanism includes a sliding sleeve 23 and a sliding rod 24. The sliding sleeve 23 is fixed on the lifting seat 22, and the sliding rod 24 is slidably engaged with the sliding sleeve 23. The sliding rod 24 extends vertically, and a linear guide rail structure is provided between the sliding sleeve 23 and the sliding rod 24 to ensure the stability and accuracy of the sliding process.

[0028] The clamp base 3 is fixedly connected to the lifting base 22. The clamping assembly includes a clamp cylinder 31, a pusher 32, a clamp arm positioning seat 33, a clamp arm 34, and a clamping block 35. The clamp cylinder 31 is mounted on the clamp base 3 and drives the pusher 32. The clamp arm positioning seat 33 is fixed on both sides of the clamp base 3. The clamp arm 34 is rotatably connected to the clamp arm positioning seat 33 via a pivot. The pusher 32 is hinged to the clamp arm 34 via a pusher connecting part 341. The clamping block 35 is fixed to the end of the clamp arm 34 and is used to clamp the pearl.

[0029] The clamping arms 34 are arranged in two symmetrical sets. Each set of clamping arms has a clamping block 35 at the end. The inner side of the clamping block 35 is provided with anti-slip texture to improve the stability when clamping the pearl.

[0030] The clamp holder 3 is equipped with a position sensor to detect the clamping status of the clamping block 35, ensuring the accuracy and reliability of the clamping action.

[0031] The clamping cylinder 31 is a double-acting cylinder. Its extension and retraction are controlled by a solenoid valve, which enables rapid switching between clamping and releasing, further improving production efficiency.

[0032] In practical applications, the pearl is first placed between the clamping blocks 35. The lifting seat 22 is then raised and lowered by the electric cylinder 21. Combined with the sliding engagement of the sliding sleeve 23 and the sliding rod 24, the height and horizontal position of the pearl can be adjusted stably and precisely. Once the pearl reaches the predetermined drilling position, the clamping cylinder 31 controls the extension and retraction movement via a solenoid valve, and the clamping arm 34 clamps the clamping blocks 35, fixing the pearl's position. At this point, the pearl can be drilled. After drilling is complete, the clamping cylinder 31 again controls the clamping arm 34 to release the pearl, completing one drilling cycle.

[0033] The pearl drilling positioning and clamping mechanism of this invention can realize the automatic positioning and clamping of pearls, significantly improving the accuracy of drilling and production efficiency, while reducing manual operation and lowering production costs.

[0034] The working principle and usage process of this utility model: After assembling the various components of this solution in sequence, work according to the above implementation methods according to actual needs to complete all working steps.
