Description

Combined multi-function arbor

The present invention relates to a machine tool holder, and more particularly to a combined multi-function holder.

The general tool machine tool bar does not need to be used according to the purpose, and the way of installing the tool is also different. Common methods include collet type, side solid type, flat type and the like, and different types of tool holders are fixed. Generally, the tool machine tool bar is usually designed. It is a special arbor. Therefore, when changing to different tools, it is necessary to replace the arbor for different purposes and it is not possible to use all the knives. Therefore, it is necessary to prepare a variety of different arbor for use, and add a lot of purchase cost, which is actually improved. Necessary.

In order to solve the problem that the general tool machine tool bar is a special tool bar and cannot be applied to different functions, so the cost of purchase is increased, the main purpose of the present invention is to provide a combined multi-function tool bar which is attached to the tool bar body. The front end forms a flange portion and an assembly groove, and can be combined with the assembly head for different purposes in the assembly groove. Therefore, the tool can be replaced only by replacing the assembly head, and the entire set of the tool holder body does not need to be replaced, thereby eliminating the need to re-purchase the tool holder body. cost.

The technical method used in the present invention is to provide a combined multi-functional cutter bar, comprising a cutter body and one or more fixing members, wherein the cutter body forms an annular flange portion at one end, The flange portion is provided with a plurality of assembly holes, and an assembly groove is recessed in the center of the cutter body along the axial direction. A cutter hole is formed along the axis of the bottom of the assembly groove. The outer side surface is provided with one or more fixing holes connected to the cutter hole; the one or more fixing members are correspondingly disposed to the one or more fixing holes.

The combined multi-functional cutter bar further includes a sleeve type assembly head, the sleeve assembly head includes an assembly base, a collet disposed on the assembly base, and a fixing the collet to the assembly base The fixing ring is corresponding to the assembly groove of the shank body.

The combined multi-functional cutter bar further includes a one-side solid assembly head, the side-mounted assembly head includes an assembly seat and a plurality of pressing members, wherein the assembly base is convexly provided with a cutter clamping portion. A plurality of pressing holes are formed on a side of the tool holding portion, and each pressing member is disposed in each of the pressing holes.

The utility model utilizes the combined multi-functional cutter bar provided, and the improved effect can be obtained that the front end of the cutter bar body forms a flange portion, and the assembly groove and the plurality of assembly holes are provided in the flange portion, and the assembly groove and the assembly hole are available. Externally combined with an assembly head, different types of tools can be clamped by changing different assembly heads, making the tool holder body a universal tool holder with a variety of options, and only need to replace the assembly head when the tool is replaced. That is, there is no need to replace the entire shank body, thus saving the cost of replacement.

In order to be able to understand the technical features and practical functions of the present invention in detail, and can be implemented in accordance with the contents of the specification, and further illustrated in the preferred embodiment shown in the figure, the following is explained in detail:

As shown in FIG. 1 and FIG. 2, the shank body 10 is formed with an annular portion 11 at the front end, and a plurality of assembly holes 111 are formed around the edge of the flange portion 11. An assembly slot 12 is defined in the center of the shank body 10 in the axial direction. A cutter hole 13 is defined in the bottom of the assembly slot 12, and two sides of the shank body 10 are connected to the tool. The fixing hole 14 of the hole 13.

The cutters 20 are correspondingly disposed in the cutter hole 13 , and each of the fixing members 30 respectively penetrates into the fixing holes 14 and firmly fixes the side surface of the cutter 20 .

As shown in FIG. 2 and FIG. 3, the combined multi-purpose tool holder A is directly assembled into the tool hole 13 of the tool bar body 10 by the cutter 20, and transmits through each The fixing member 30 is coupled to the shank body 10 in a side-fixing manner.

The manner of use of the second preferred embodiment of the present invention is as shown in FIG. 4 to FIG. 6 , which is based on the application of the first preferred embodiment, and the difference is:

The combined multi-function arbor A1 further includes a sleeve-type assembly head 40. The sleeve-type assembly head 40 includes an assembly base 41, a collet 42 disposed on the assembly base 41, and a collet 42 The fixing ring 43 of the assembly base 41 and the plurality of locking members 44 are coupled to the assembly groove 12 of the shank body 10, and the assembly seat 41 is respectively inserted through the locking members 44 and correspondingly In combination with each of the fixing holes 14, the cutter 20 is correspondingly mounted to the collet 42 and is tightly locked by the fixing ring 43, so that processing can be performed.

The manner of use of the third preferred embodiment of the present invention is as shown in FIG. 7 to FIG. 9, which is based on the application of the first preferred embodiment, and the difference is:

The combined multi-purpose cutter bar A2 further includes a one-side solid assembly head 50, which includes an assembly seat 51, a plurality of pressing members 52, and a plurality of locking members 53, the assembly seat 51. A tool holding portion 511 is protruded forwardly, a tool hole 512 is formed in the center of the tool holding portion 511, and a plurality of wires are connected to the tool hole 512 at the side of the tool holding portion 511. The assembly hole 51 is coupled to the assembly groove 12 of the shank body 10, and the assembly seat 51 is respectively inserted into each of the locking members 53 and coupled to each of the fixing holes 14. The cutter 20 is correspondingly worn. The tool hole 512 is disposed in the tool hole 512, and the pressing member 52 is correspondingly disposed on each of the pressing holes 513, and is pressed against the side of the tool 20 to perform machining.

The present invention is provided with a flange portion 11 and an assembly groove 12 in the cutter body 10, which can be used for assembling assembly heads 40 and 50 for different purposes to perform different processing. When the tool replacement is to be performed, only the replacement and replacement are required. The heads 40, 50 are assembled without the need to replace the entire shank body 10, so that the cost of additional burrs can be saved, and the use of multiple functions can be provided, which is quite practical.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Any person having ordinary knowledge in the art can use the present invention without departing from the technical features of the present invention. Equivalent embodiments of the novel modifications or modifications made by the novel teachings are still within the scope of the novel features.
