Problems solved by technology

It can be seen from the figure that the diameter of the tool holder body is small, which can complete the processing of the deep hole in material 1, but this type of tool holder is not very versatile, and one tool holder can only hold tools of the same diameter , and the tool holder itself needs a hot-loading machine to load the tool into the clamping cavity

Embodiment Construction

[0017] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings of the description.

[0018] Such as Figure 4 , Figure 5 As shown, a kind of worm gear type collet locking mechanism, comprises the body 8 that the right half part is shaped on cavity (as can be seen from the figure, the left end of this cavity is cylindrical, and the right end is conical); A tapered collet 9 matched with the body is arranged in the cavity (the tool is clamped in the clamping cavity of the tapered collet); a worm wheel 10 is also arranged in the cavity (the worm wheel is coaxial with the body installation), the left end of the worm wheel 10 is threadedly engaged with the body (at 10A among the figures), and the right end of the worm wheel 10 is threaded at the left end of the tapered collet 9 (at 10B among the figures); the body 8 Also be provided with a worm screw 11 that cooperates with described worm gear on it.

Abstract

The invention relates to a locking mechanism of machine tools and provides a lock device which is characterized by convenient replacement and regulation of tool, compact structure and high holding precision and can accurately, reliably and conveniently hold and fix the tool. The technical scheme of the invention is that a worm-gear type collet chuck locking mechanism comprises a main body having a cavity on a right half part; the right end of the cavity is of a cone shape; a cone-shaped collet chuck which is used for holding a knife handle and is matched with the cavity is arranged in the cavity; and the cone-shaped collet chuck is provided with a plurality of contraction joints along a cone-shaped bus direction. The inner side of the main body is provided with a pair of worm-gear mechanisms used for exerting an acting force on the cone-shaped collet chuck along the axial direction of the main body. A worm wheel in the worm-gear mechanism is coaxially arranged on the main body; the left end thereof is matched with the main body by the thread; the right end is matched with the left end of the cone-shaped collet chuck by the thread; and the thread directions of the left and right ends are reverse.

Description

technical field [0001] The invention relates to a locking device for machine tools, in particular to a locking mechanism for fixing tools such as milling cutters and drill bits on various metal cutting machine tools. Background technique [0002] In the process of production practice, it is often encountered that the diameter of the tool holder is too large to process deep holes or deep bottoms. The tool holding handles on the existing market are generally expensive and have poor interchangeability (one tool handle can only hold tools of the same diameter) split type tool handles and tools that need to be removed and pulled to lock the tool. handle. [0003] figure 1 Shown is a conventional collet nut type tool handle, including a tool handle body 2, a lock nut 3 is installed at the lower end of the tool handle body, and the tool is clamped in the clamping cavity at the lower end of the tool handle body and passed through the lock nut 3 lock tight. This type of tool hold...
