Technical Field
[0001] This utility model relates to the field of milling cutter processing technology, specifically to an automated chuck for T-type milling cutter processing. Background Technology
[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, each cutting tooth cuts off the excess material of the workpiece in turn. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. A chuck is a mechanical device on a machine tool used to clamp workpieces. It is mostly used on lathes, but also on milling machines or drilling machines. It is mainly used to fix rotating parts.
[0003] Among the existing technologies, the authorized announcement number CN112404473A proposes an automated chuck operation method for milling cutters, which includes a chuck body and a clamping block. The chuck body has a connecting groove in the middle, and a positioning groove is formed on the side wall of the connecting groove. A rotating disk is movably connected to the inner cavity of the connecting groove. A positioning ring is fixedly installed on the side wall of the rotating disk. Engaging ring 1, engagement ring 2, engagement ring 3 and engagement ring 4 are fixedly installed on the left side of the rotating disk.
[0004] In existing technologies, the clamping components of the device cannot be quickly replaced or disassembled, and cannot be changed according to the fixing requirements of the T-slot cutter. During use, vibration can easily cause the gears to rotate, making the T-slot cutter fixing easy to loosen. To address this, we propose an automated chuck for T-slot cutter machining. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an automated chuck for T-type milling cutter processing. It can realize the quick disassembly and replacement of the clamping unit, and can form a reliable fixed clamping mechanism with the sliding column and the fixing device through the gear-driven threaded rod, so as to prevent the device from loosening when fixing the T-type milling cutter during use. It can effectively solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated chuck for T-type milling cutter machining, comprising a circular mounting plate, a replaceable component, a movable component, and a transfer component;
[0007] Circular mounting plate: The upper part is equipped with movable components and transfer components;
[0008] Replaceable assembly: Includes a mounting plate, limiting holes, an arc-shaped end mill holder plate, slots, and connecting rods. Three connecting rods are evenly slidably connected to the inner side of the mounting plate, and the arc-shaped end mill holder plate is fixedly connected to the inner side of each connecting rod. T-slots are formed on the outer sides of the connecting rods. Three limiting holes are evenly formed at the upper end of the mounting plate, and three slots are evenly formed on the outer side of the mounting plate. The replaceable assembly allows for quick assembly and disassembly via the slots on the mounting plate. The three connecting rods drive the arc-shaped end mill holder plate to move synchronously. The limiting holes provide a positioning reference, and the T-slot structure ensures connection stability, forming a modular clamping unit with the characteristics of quick replacement and strong adaptability, allowing for replacement according to the fixing requirements of the end mill.
[0009] Furthermore, the movable component includes a chuck body, sliding columns, a threaded rod, a gear, and a T-connecting block. The chuck body is fixedly connected to the upper center of the circular mounting plate. Three sliding columns are slidably connected to the inner side of the chuck body, and a T-connecting block is fixedly connected to the inner side of each sliding column.

The T-connecting block and the connecting rod form a linkage mechanism, and the chuck body provides guiding support, constituting a precision radial adjustment system with uniform clamping force and high positioning accuracy.
[0010] Furthermore, the movable component also includes threaded posts and locking pins. Three threaded posts are fixedly connected to the upper inner side of the circular mounting plate.

The threaded posts pass through the limiting holes for positioning, the locking pins restrict the rotational freedom of the chuck body, and the nuts provide locking force, which has the advantages of preventing loosening and resisting torsional vibration.
[0011] Furthermore, the transmission assembly includes a worm gear and a gear ring. The worm gear is rotatably connected to the lower outer end of the chuck body, and the gear ring is fixedly connected to the upper end of the worm gear. The gear ring meshes with a gear. The worm gear drives the gear ring to rotate, converting the circular motion into radial feed through meshing with the gear. Its self-locking and reliable characteristics allow it to form a reliable clamping mechanism with the sliding column and fixing device via a gear-driven threaded rod, preventing loosening when the device is fixing the T-slot milling cutter during use.
[0012] Furthermore, the transmission assembly also includes a fixed plate, a worm gear, and a motor. Two fixed plates are fixedly connected to the upper end of the circular mounting plate, and a worm gear is rotatably connected between the two fixed plates. The worm gear engages with a worm wheel. A motor is fixedly connected to the upper end of the circular mounting plate, and the output shaft of the motor is fixedly connected to one end of the worm gear. The motor drives the worm gear to rotate, the fixed plates ensure transmission stability, and the worm wheel and worm gear pair enables the conversion of the motion direction, forming a power input system. The self-locking property of the worm wheel and worm gear prevents the chuck from loosening when fixing the T-slot milling cutter.
[0013] Furthermore, it also includes mounting holes, a first protective shell, and a second protective shell. The upper end of the circular mounting plate has multiple mounting holes. The upper end of the worm gear is fixedly connected to the second protective shell, and the upper end of the chuck body is fixedly connected to the first protective shell. The first and second protective shells are slidably connected. The mounting holes provide a standard interface, and the first and second protective shells form a nested protective structure. The sliding connection design ensures freedom of movement and features dustproof, waterproof, and convenient maintenance.
