Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a work clamping device for a cutting machine such as a planing machine, a shaping machine, and a vertical machine.

[0002]

[Prior art]

 Conventionally, when cutting a work with a milling machine or the like, as a means for fixing the four corners of the work, a T-shaped head bolt is locked in a T-groove on the table top of the board and the block and the work are bolted via a presser foot. Is detachably tightened and fixed by.

However, when the T-shaped head bolt protrudes extremely with respect to the height of the work, there is a risk of interrupting the work on the table surface, for example, by contacting the ram or collect chuck. Therefore, it is necessary to prepare a plurality of sets of four bolts that do not come into contact with them and that have an appropriate length that suits the height of the work, in advance, and it is extremely complicated to store and manage them. .

[0004]

[Problems to be solved by the device]

 Therefore, this invention was devised in order to eliminate the above-mentioned respective drawbacks, and uses a bolt member constituted by combining a plurality of pillars having different heights, and a block body is also used. It is intended to provide a work clamping device for a cutting machine which is highly efficient and does not come into contact with a ram, a collect chuck or the like by using a combination of suitable heights.

[0005]

[Means for Solving the Problems]

 Therefore, this invention is a work clamping method in a cutting machine in which a T-shaped head bolt is locked in a T groove on the upper surface of a table and a block and a work are detachably fastened with a bolt through a presser foot. In the fixing device: a bottom nut having a T-shaped head, a plurality of intermediate columns having different heights each having a T-shaped projection and a T-shaped groove at the upper and lower ends, and a T-shaped groove at the lower end. It consists of an upper strut with a bolt installed at its upper end, a bolt member consisting of a presser foot that loosely fits the upper strut, a washer, and a nut, and a plurality of block bodies each higher than the intermediate strut; It consists of a work tightening and fixing device in a cutting machine characterized by a quick combination table of bolt members and block bodies used according to the requirements.

[0006]

[Action]

 In using this device, first, according to the height of the work, look at the quick view combination table to determine how many heights of the intermediate column and block body should be combined, and Insert a bottom nut with a T-shaped head into the T-shaped groove, erect a bolt member composed of a plurality of intermediate support columns that is lower than the work height, and install an upper support column at the upper end to block it. The body is also made up of a combination of a plurality of objects with different heights, a presser foot is laid over the work and the upper surface of the block body, a bolt is projected, and a nut is tightened.

[0007]

[Embodiment 1] Next, an optimum embodiment of the present invention will be described in detail. A T-shaped head bolt is locked in a T groove (B) on the upper surface of a table (A) to hold a block and a work together. In a device for tightening and fixing a work in a cutting machine, which is detachably tightened and fixed by a bolt through gold; a bottom nut (1) having a T-shaped head and a T-shaped protrusion (X ) And a T-shaped groove (Y), and a plurality of intermediate columns (2a, 2b, 2c) having different heights, and an upper part having a T-shaped groove (Y) at the lower end and bolts at the upper end. The pillar (3), a bolt member (4) for loosely fitting the upper pillar, a washer (5), and a bolt member composed of a nut (6) and a block body (7a, 7a, 7b, 7c); bolt members and blocks used according to the height of the work (W) It is composed of a quick fixing combination table (Z) with a body, and is a device for tightening and fixing a work in a cutting machine.

The T-shaped protrusions of each of the intermediate columns (2a ...) May be formed in a dovetail shape, and the corresponding T-shaped grooves may also be shaped so as to match them, and the T-shaped protrusions (X) may be stoppers. (S) may be formed, and the T-shaped groove may also be formed with a corresponding recess (S ').

The presser foot (4) straddles the intermediate strut (2) and the block body (7), and the upper end surface of the presser foot (4) has the intermediate strut (2) and the block body (7). 7) A recess (4a) is formed in an arc shape so that it can be tightened in conformity with the difference in height from 7), and the bottom of the washer (5) fitted in the recess (4a) has an arc-shaped projection (5a). Is formed.

[0010]

[Effect of device]

 According to the present invention, the present invention has the above-described structure. According to the present invention, plural kinds (three kinds in the present application) of the intermediate support column (2) and the block body (7) having different heights are used. If they are prepared separately, they can be combined and fixed to multiple heights (7 in this application), and fine adjustments can be made with nuts, making it easy to tighten the nuts. -It can be performed quickly, and the bolts are too long to interfere with the operation of the cutting tool, resulting in extremely beneficial effects.
