Description

Technical Field

[0001] The utility model specifically relates to a quick-loading and disassembling tool holder for mechanical processing, and belongs to the technical field of loading and disassembling tool holders. Background Art

[0002] The loading and unloading tool holder is a machine tool accessory, which is mainly used to clamp the tool holder. After clamping, it is convenient to remove the tool from the tool holder, or install the tool on the tool holder. After the installation is completed, the tool holder can be removed from the loading and unloading tool holder; for example, Chinese Patent Publication No.: CN211053589U discloses an axial power tool holder tool disassembly device, which can fix the power tool holder inside the tool unloader through the clamping mechanism inside the tool unloader, and then lock it by the locking device outside the tool unloader, so that the tool can be installed and disassembled by one operator. For example, Chinese Patent Publication No.: CN209919783U discloses an axial power tool holder tool disassembly device for a CNC machine tool, which limits the rotation of the tool holder by setting a jaw, so that it is convenient for a single person to disassemble. When the above two structures cannot achieve tight clamping of the tool holder, especially for disassembly of the balance nut end of the tool holder, a large rotational force needs to be applied. If the tool holder cannot be stably locked, when the force is applied to the tool holder, it is easy to scratch the tool holder due to shaking or impact. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a quick-loading and disassembly tool holder for mechanical processing, which has high disassembly and assembly efficiency, can protect the tool handle, and can match tool handles of multiple models.

[0009] When loading and unloading the nut end of the tool handle, adjust the screw-in position of the sleeve according to the size of the tool handle. After the adjustment of the sleeve is completed, select a sleeve that matches its size and embeds it into the second sleeve seat, and adjust the limit head at the position of the convex rod according to the size of the tool handle. The convex hole limits the front end of the block, and the slide groove limits the circumference of the block. Then, the top pressure spring presses the block inward. After the adjustment is completed, adjust the notch of the tool handle's disk to align with the block, and then use a nut wrench to load and unload the nut. After loading and unloading is completed, take out the tool handle.

[0010] Furthermore, holes are provided on opposite sides of the open slot, pins are movably embedded on both sides of one end of the swing arm, and a spring body is pressed on the inner side of the pin.

[0011] Furthermore, a plurality of threaded countersunk holes are spaced apart on the convex rod, and the limit head is screwed to a threaded countersunk hole. When in use, a threaded countersunk hole is selected according to the size of the tool handle, and the limit head is screwed to the threaded countersunk hole to limit the position.

[0012] Furthermore, the tool holder base comprises a bottom plate fixed on the work station, and a right-angle plate is integrally formed on the top of the bottom plate; the bottom plate and the right-angle plate are integrally cast.

[0013] Furthermore, the second cylinder seat is integrally formed with a card seat with a hollow bottom on the outer side of the sleeve, and a card plate is inserted into the card seat. When loading and unloading the nut end of the tool handle, the card plate is continuously pushed forward to press the top surface of the card plate against the upper end surface of the tool handle, and then the screw-in position of the sleeve body is adjusted to make the sleeve body press against the lower end of the tool handle, the upper end of the tool handle is pressed by the card plate, and the circumference of the tool handle is clamped by the clamping block, thereby achieving stable clamping of the tool handle.

[0014] Compared with the prior art, the utility model of the quick-loading and disassembly tool holder for mechanical processing can quickly disassemble and assemble by adopting the clamping and limiting methods for the rivet end of the tool handle with small force. When disassembling and assembling the balance nut end of the tool handle, the tool handle is tightly locked through the reduced diameter opening of the sleeve body before disassembly and assembly, which can protect the tool handle and can match tool handles of multiple models.
