Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and more specifically, to a grinding tool for a large gantry mill. Background Technology

[0002] In existing technologies, while grinding tools used in large gantry mills can perform basic grinding operations, they still suffer from many inconveniences in adjusting the angles of the grinding components. Specifically, existing designs often lack flexible and efficient angle adjustment functions, requiring operators to expend considerable time and effort to adjust the angles of the grinding components, making it impossible to quickly meet the grinding requirements of different workpiece angles. This adjustment method is typically rudimentary, relying on manual adjustment, prone to errors, and difficult to meet the demands of high-precision and high-efficiency machining.

[0003] Furthermore, while existing grinding tools can achieve adjustments in certain positions, it is difficult to simultaneously meet the requirements of position change and position fixation. Typically, when the position of the grinding components needs to be adjusted, it often results in unstable positions or insecure locking, thereby affecting grinding accuracy and work efficiency. The position fixing mechanism in traditional designs mostly relies on locking devices or snap-fit ​​components in the mechanical structure, but these designs do not fully consider the balance between multi-position adjustment and rapid fixation, which can easily lead to slight displacement of the grinding components during processing, thus affecting the processing quality.

The linkage ring is rotatably mounted on the outer wall of the clamping tube, the rotating ring is mounted on the top end of the linkage ring, the mounting groove is provided through the side wall of the clamping tube, and the embedded plate is rotatably mounted in the mounting groove. The two ends of the pulling plate are rotatably connected to the embedded plate and the rotating ring. The rotation of the rotating ring drives the pulling plate to rotate, causing the embedded plate to be embedded in the side wall of the clamping rod.

[0008] The present invention is further configured such that the fixing auxiliary mechanism includes a limiting ring, an outer fixing ring, a spinning plate, a spring rod, and a mating ring. The outer fixing ring is fixedly installed on the outer wall of the clamping tube, the limiting ring is installed on the outer wall of the outer fixing ring to limit rotation, the spinning plate is installed at the bottom end of the limiting ring, the spring rod is installed laterally on the outer fixing ring, and the mating ring is installed at the top end of the rotating ring.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a grinding tool for large gantry mills, which has the following beneficial effects:

[0017] This utility model is equipped with a space adjustment mechanism. Through components such as a longitudinal shift frame, an adjustment plate, and a clamping tube, it can achieve precise position adjustment of the grinding component. The clamping rod engages with the clamping tube through the adjustment hole, which can quickly lock the position of the grinding component and ensure its stability and reliability during the adjustment process. Multiple sets of adjustment holes on the adjustment plate provide multiple adjustment positions, making angle adjustment more flexible and able to meet different processing needs. This design makes the space adjustment of the grinding tool more convenient, improves work efficiency, and reduces the complexity of manual adjustment.

[0018] This utility model is equipped with a position fixing mechanism. Through the cooperation of components such as a linkage ring, a rotating ring, and a pulling plate, the grinding assembly can be stably fixed in the required position after adjustment. The rotation of the rotating ring drives the pulling plate, which in turn causes the embedding plate to embed into the side wall of the snap-fit ​​rod, achieving precise position fixing. This fixing method ensures the firmness of the grinding assembly and can effectively prevent position displacement during high-speed grinding, thereby improving processing accuracy.

[0019] This utility model is equipped with a fixing auxiliary mechanism, which consists of a limiting ring, an outer fixing ring, a spinning plate, and a spring rod. This auxiliary mechanism helps to further enhance the fixing stability of the grinding assembly. The spinning plate achieves fixing by pressing against the spring rod, ensuring that the rotating ring will not loosen or shift during rotation, thus enhancing the fixing effect. This mechanism effectively improves the reliability of fixing, especially in complex or high-load processing environments, providing additional support and reducing the risk of equipment failure.

[0038] The operator first adjusts the overall position of the device using the longitudinal shift frame 2, so that the adjusting plate 4 reaches the required position. The clamping rod 7 passes through different adjusting holes 5 and extends into the clamping tube 6 to fix the mounting plate 3 in the required position. When the mounting plate 3 is fixed to the clamping tube 6 by the clamping rod 7, the position fixing mechanism starts to work. The rotating ring 10 drives the pulling plate 11 to rotate, so that the embedding plate 13 is embedded into the side wall of the clamping rod 7, further ensuring that the clamping rod 7 is not easy to loosen. The fixing auxiliary mechanism provides additional support. The combination of the outer fixing ring 15 and the limiting ring 14 restricts the free movement of the rotating ring 10, while the spinning plate 16 pushes the spring rod 17 to extend into the mating ring 18, ensuring that the rotating ring 10 remains stable during rotation and preventing any possible displacement or loosening.
