Locking knife seat

This creation relates to an accessory for a machine tool, in particular to a lock holder that is small in size and can save space.

The cutter bar is a machine tool component that connects the cutter for milling and the spindle for driving. The cutter bar uses a collet to clamp the cutter. The common way of clamping the cutter by the collet can be roughly divided into the following two types: The first type is a screw cap screw fixed to the front end of the arbor, the screw cap is used to press the collet, and the collet is pressed to clamp the cutter; the second type is to pull the collet by a screw bolt coupled to the arbor The clip rotates the pull bolt from the rear end of the cutter bar, and the pull bolt pulls the collet to move toward the rear end of the cutter bar, and presses the collet to clamp the cutter.

When the tool is fixedly coupled to the arbor, the arbor is first placed on the locking knives, and then the tool is fixedly coupled to the arbor by hand; the early locking knives are provided with perforations for piercing the shank, perforating The axial direction extends along the upper and lower directions of the locking knife seat, and the user puts the arbor on the perforation provided by the locking knife seat, and then tightens the screw cap with a hand tool such as a wrench to make the screw cap suppress and force Tightening the collet allows the collet to clamp the tool; however, this type of lock holder is only suitable for the first type of tool.

In order to make the locking knife seat applicable to the first and second clamping tools, the operator has designed another locking knife seat. The locking knife seat is provided with two sockets and is respectively disposed on the two sockets for the cutter bar. Two perforations are inserted, wherein the axial direction of one perforation extends along the upper and lower directions of the locking knife seat, and is suitable for the first type of clamping tool, and the axial direction of the other perforating is along the lateral direction of the locking knife seat The direction extension can be applied to the second clamping tool method of pressing the clamp with the bolt.

Although the aforementioned locking knife seat can be applied to two common clamping tool modes at the same time, it is necessary to separately provide two sockets and two perforations, thereby respectively corresponding to two different clamping tool modes, thereby knowing that the existing The locking knife seat has the problem of large volume and space, and there is room for improvement and improvement in structure.

In order to solve the problem that the existing lock tool holders are designed corresponding to two kinds of clamped cutters, the volume is large and the space is occupied. The present invention proposes a lock knife holder which is provided with a pivotable holder holder, which can change the axial direction of the perforation for use in two types of clamping tools, and can achieve the purpose of reducing the volume and the installation space.
