Description

Technical Field

[0001] This utility model relates to the field of vertical milling machine tool clamping technology, and more specifically to a simple clamping device for interchangeable taper shank milling cutters. Background Technology

[0002] Compared to horizontal milling machines, the main difference between vertical and horizontal milling machines is the vertical spindle arrangement. Besides the spindle arrangement, the worktable can be raised and lowered. Vertical milling machines offer more flexible milling cutters and a wider range of applications. They can use end mills, indexable cutters, drills, etc., and can mill keyways, planes, and bore holes.

[0003] The X5032 vertical milling machine is a general-purpose, high-power metal cutting machine tool. It uses face cutters, end mills, cylindrical cutters, saw blade cutters, circular cutters, and various form cutters to process various parts. It comes pre-assembled with a tapered intermediate sleeve, a universal indexing head, a set of milling chucks, and various milling cutters. However, during milling, the different sizes of milling cutters used on the workpieces lead to frequent tool changes. Furthermore, the vertical milling machine only comes with one tool holder with a spring clip, and it can only hold straight shank end mills with diameters of φ4-φ20. After the cutter is securely clamped by the milling chuck, it is mounted on the tapered intermediate sleeve and then connected to the cutter drawbar shaft. For clamping tapered shank end mills, the chuck has significant limitations; the tool holder is not universal. If the original tool drawbar is damaged, the entire tool drawbar body needs to be machined, increasing the difficulty of machining the tool drawbar and also increasing the consumption of manpower, material resources, and financial resources. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems by providing a simple clamping device for a replaceable taper shank end mill. After the original tool drawbar is damaged, only the replaceable threaded end needs to be machined, which reduces the difficulty of machining the tool drawbar and greatly reduces the consumption of manpower, material resources and financial resources.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a simple clamping device for a replaceable taper shank end mill, including a taper shank end mill, one end of which is detachably connected to a replaceable end mill shank shank, the other end of which is snapped together with an improved tool pull rod, and the outer sides of the improved tool pull rod and the replaceable end mill shank are fitted with knurled nut sleeves.

[0006] To facilitate the installation of the taper shank end mill and the replaceable end mill holder, as a preferred embodiment of the simple clamping device for the replaceable taper shank end mill of this utility model, one end of the taper shank end mill is fixed with an internal thread nut, and one end of the replaceable end mill holder is fixed with an external thread screw, with the external thread screw threadedly connected to the internal thread nut.

[0007] In order to install the replaceable milling cutter shank and the improved tool drawbar, as a preferred embodiment of the simple clamping device for replaceable taper shank milling cutters of this utility model, the other end of the replaceable milling cutter shank is fixed with a limiting boss, and the inner wall of the knurled nut sleeve is fixed with a limiting ring, the limiting ring abutting against the limiting boss.

[0008] To prevent the replaceable milling cutter shank from wobbling inside the knurled nut sleeve, as a preferred embodiment of the simple clamping device for replaceable tapered shank milling cutters of this utility model, a male-female buckle protrusion is fixed on the side of the limiting boss away from the external threaded rod, and a male-female buckle groove is opened at the end of the improved cutter pull rod near the knurled nut sleeve, and the male-female buckle groove and the male-female buckle protrusion are snapped together.

[0009] In order to install the knurled nut sleeve with the improved tool drawbar, as a preferred embodiment of the simple clamping device for replaceable taper shank end mills of this utility model, the inner wall of the knurled nut sleeve is provided with internal threads, and the outer wall of the improved tool drawbar is provided with external threads, with the external threads and internal threads being threadedly connected.

[0010] The beneficial effects of this utility model are as follows: When the tool drawbar is damaged, by first removing the knurled nut sleeve, the replaceable milling cutter holder along with the tapered shank milling cutter is separated from the improved tool drawbar. Then, the replaceable milling cutter holder is separated from the tapered shank milling cutter, so only the replaceable milling cutter holder needs to be machined to fit the replaced tool drawbar. There is no need to machine the tapered shank milling cutter again, thereby reducing the machining difficulty of the tool drawbar and greatly reducing the consumption of manpower, material resources and financial resources.
