The present invention relates to a clamp used for stably securing a workpiece to a worktable.

The worktable for machining uses various fixing devices to fix the workpiece without moving.

1A and 1B are a perspective view and a front view showing a structure and a state of use of a clamp that has been conventionally used for the above-mentioned uses.

The clamp is a fixed bolt (2) inserted into the T-shaped groove 110 of the work table, a support block (1) positioned to face the workpiece, and the support block (1) is fitted to the upper portion of the fixed bolt (2) ) And a jaw (4) having a long hole (4a) formed in the center positioned so as to be in contact with the workpiece (200) a predetermined length, and the jaw (4) is fixed to the long hole (4a) to press-fix the workpiece It consists of a nut (3) fastened to the bolt (2).

In the above-described conventional clamp, the fixing bolt 2 fixed to the work table 100 and the workpiece 200 fixed by the jaw 4 are fixed depending on one nut 3 so that the fixed state is fixed. It becomes unstable.

Therefore, the conventional clamp causes the shaking or slipping of the fixed workpiece 200 during machining, which makes it difficult to precisely process the defects during the process and has a high risk of safety accidents.

In addition, the conventional clamp uses a separate support block (1), so when the workpiece is large, there is a problem that it is difficult to work because there is not enough space to place the support block.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a clamp that prevents shaking or slipping of a workpiece and installs in a narrow space.

According to a feature of the present invention for achieving the above object, the clamp is fixed to the T-shaped groove to fix the workpiece to the work table having a T-shaped groove and the nut fastened to the fixed bolt, and the center A V-shaped support block having screw holes at both ends and a fixing hole fixed by the fixing bolt and a nut, a plate-shaped jaw having a predetermined length of a long hole in the longitudinal direction, and fitted into one end of the long hole of the jaw. A support bolt and a nut fastened to one side of the screw hole of the block to fix the jaw at a predetermined position, and the other end of the jaw is pressed into the long hole to press the workpiece, and the pressure bolt is fastened to the other screw hole of the support block.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments, operations and effects of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2A is an exploded perspective view showing the overall configuration of the clamp according to the present invention.

The clamp includes a jaw (30) for fixing the workpiece, an operating portion for operating the jaw to pressurize the workpiece, a support block (20) for supporting the operating portion to be fixed at a predetermined position of the work table, It consists of a fixing bolt 11 for fixing the support block to the T-shaped groove 110 of the work table 100 and a nut 12 fastened to the fixing bolt.

The tub 30 has a structure in which a long hole 31 of a predetermined width is formed in the longitudinal direction. The support block 20 is provided with a screw hole 22 at both ends and a fixing hole 21 fixed to the center by the fixing bolt 11 and the nut 12 and has a V-shape as a whole. And the operation part is fitted to one end of the long hole 31 of the jaw 30 and is fastened to one side of the screw hole 22 of the support block 20 to support the support bolt 41 for fixing the jaw 30 in a predetermined position and The nut 42 and the other end of the jaw 30 are pressed into the long hole 31 so as to pressurize the workpiece 200 to be fastened to the other side screw hole 22 of the support block 20 by a bolt 50. It is composed.

Figure 2B is a front view showing a state of use of the present invention having the above-described configuration, the process of fixing the workpiece through the present invention with reference to the drawings as follows.

First, the head 11a of the fixing bolt 11 is inserted into the T-shaped groove 110 at a position close to the workpiece 200 positioned above the work table 100, and the bolt is supported to penetrate the fixing hole 21. Position the block 20 to fix the support block to the worktable with the fixing nut 12. Then, the support bolts 41 and the nuts 42 and the pressure bolts 50 fastened to the screw holes 22 on both sides of the support block 20 are adjusted to adjust the long holes 31 of the jaws 30 therebetween. It is fitted and positioned so that one end is in contact with the upper surface of the workpiece 200.

In this state, the support bolt 41 and the nut 42 are adjusted again to fix one side of the jaw 30, and finally, tighten the pressure bolt 50 to fix the workpiece 200.

The separation process after the workpiece is processed in the reverse order of the above-described fixing process.

In this way, the support block 20 is fixed to the work table 100 by the fixing bolt 11 and the fixing nut 12 in the process of fixing the workpiece 200, the jaw 30 is the support bolt 41 And are fixed to the support block 20 by the nut 42 and the pressure bolt 50, respectively, to stably fix the workpiece.

Therefore, the present invention prevents safety accidents by preventing shaking or slipping of the workpiece during machining, and enables precise processing.

In addition, the present invention is easy to fix the work, even if the workpiece is located at the corner of the block is large, if only fixed on the center of the support block does not use a large area and can be securely fixed to the workpiece to improve workability There is an advantage to improve the efficiency.
