Description

Technical Field

[0001] This utility model relates to the field of chuck technology, specifically to an aluminum chuck with a reinforced adapter structure. Background Technology

[0002] The woodworking lathe chuck is a core fixture for home woodworking enthusiasts to process wood (such as irregularly shaped parts like cylinders and spheres). Its core function is to clamp the wood with jaws and rotate synchronously with the lathe spindle to ensure processing accuracy. Home users typically process wood with small diameters, so chuck diameters are usually designed to be within 100mm to accommodate the miniaturized spindles of home lathes. Since home users often operate the lathe alone, and the lathe is often placed in a home workshop or on a balcony, an excessively heavy chuck is not only inconvenient to move and install, but may also exceed the load-bearing capacity of the home lathe spindle, affecting the equipment's lifespan. Therefore, there is a clear need for lightweight chucks.

[0003] However, in existing technologies, woodworking lathe chucks are generally made of steel, which is laborious for home users to install and disassemble by a single person. To solve the problem of excessive weight of steel chucks, a solution using aluminum chuck bodies has been proposed. The chuck body is usually connected to the medium carbon steel spindle of the lathe by a threaded connection. When the internal thread of the aluminum chuck mates with the external thread of the medium carbon steel spindle, the hardness difference between the two is too large. During the installation, disassembly, and processing of the chuck body, the tooth profile of the aluminum internal thread is easily deformed and worn by the medium carbon steel thread, and even stripping may occur. This causes the chuck to be unable to stably mate with the spindle, resulting in direct scrapping and shortening the service life of the chuck. Improvement and optimization are needed.

[0004] Therefore, this utility model proposes an aluminum chuck with a reinforced adapter structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum chuck with a reinforced adapter structure to solve the problems mentioned in the background art.

[0007] Preferably, the connecting assembly includes positioning posts, T-shaped sliding plates, L-shaped clamping plates, inserts, limiting collars, hand-tightening bolts, and fastening buckles. The positioning posts are equidistantly arranged in a ring on the end wall of the connecting ring body, and the bottom wall of the fixed mounting ring is provided with equidistantly arranged positioning grooves in a ring. The positioning posts are inserted into the positioning grooves.

[0008] Preferably, the connecting ring body has T-shaped grooves equidistantly arranged on its peripheral wall, and a T-shaped sliding plate is movably engaged in the T-shaped groove.

[0026] Working principle: Align the positioning pin 5 of the adapter with the positioning groove 6 of the fixed mounting ring 2 and gently insert it, ensuring that the end wall of the connecting ring body 3 is in contact with the bottom wall of the fixed mounting ring 2. Slide the T-shaped sliding plate 8 inward along the T-shaped sliding groove 7, driving the L-shaped locking plate 9 to move, so that the insert 10 is fully inserted into the slot 11 until the L-shaped locking plate 9 is in contact with the periphery of the fixed mounting ring 2. Slide the limiting sleeve 12 from the bottom side of the connecting ring body 3, so that the L-shaped locking plate 9 is locked into the limiting groove 13 of the limiting sleeve 12 until the end wall of the limiting sleeve 12 contacts the inner side of the L-shaped locking plate 9. Tighten the hand-tightening bolt 15 on the protrusion 14, so that the screw is inserted into the limiting hole 16 of the connecting ring body 3. Rotate the fastening buckle 17 so that its S-shaped groove locks the protrusion 18 of the hand-tightening bolt 15, and the installation is completed. Connect the internal threaded tube 4 of the adapter to the lathe spindle thread, adjust the jaws of the aluminum chuck body 1, clamp the wood to be processed, and then start the lathe for processing. The high-strength internal threaded tube of the adapter directly mates with the carbon steel spindle thread of the lathe, avoiding the problem of hardness mismatch between the aluminum chuck body and the spindle, extending the overall service life of the chuck. The adapter is small in size and low in weight, meeting the convenience needs of home users for single-person installation and disassembly. The adapter can be installed and disassembled without special tools by manually operating parts such as hand-tightening bolts and fastening buckles.
