Description

Clamp structure for supporting workpiece

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp structure for supporting a workpiece, and more particularly, to a workpiece supporting clamp structure capable of accurately fixing various workpieces requiring precision.

In general, the workpiece for processing the workpiece is to be precisely fixed by the clamp on the table so that the workpiece can be precisely processed, the workpiece is fixed to the table by the clamp, using a variety of clamps according to the shape and purpose of the workpiece To fix the workpiece to the table.

Such a clamp is generally manufactured by processing a long rod shape and bending it into a U shape or by processing a rectangular material with a laser for accuracy and productivity.

However, such a clamp for a workpiece using a laser has a closed end in which the shape of the clamp is changed due to a high temperature during the laser processing operation or both ends of the clamp are opened while the clamp is in use, so that the clamp does not function as a clamp.

1 is a perspective view showing a pre-processing material for explaining a conventional work support clamp structure, Figure 2 is a perspective view showing a post-processing material for explaining a conventional work support clamp structure.

Such a conventional clamp 140 is coupled to the height adjusting device to the table, but the screw is coupled to the height adjusting device to adjust the height of the top by rotating or reverse rotation, and the fixture to maintain the appropriate distance to the table The upper part of the fastener is formed into a screw rod and is provided with a fixing nut provided with a washer on the screw rod. The workpiece is placed on a table while maintaining a proper distance to the fastener, and the round part 141 of the clamp 140 is mounted. ) And the front end portion are placed in the height adjusting device and the workpiece, and the screw rods of the fasteners protruding into the space portion between the support pieces 142 of the clamp 140 are coupled with nuts.

In particular, in the case of such a clamp 140, the shape change in the round portion is severely generated during the laser processing, which causes a problem that the front end of the support piece 142 is opened, this phenomenon is the length of the clamp 140 The longer the deeper the longer the clamp 140, the higher the defective rate due to laser processing, as well as using only one side of the clamp 140, there was a problem that the efficiency is lowered.

Therefore, the main object of the present invention is to provide a clamp structure for supporting the workpiece to improve the efficiency by not only to improve the productivity and accuracy by suppressing the occurrence of defects even when machining the clamp with a laser, but also to use both ends. There is.

Another object of the present invention is to provide a clamp structure for supporting a workpiece to prevent the occurrence of a defect by opening both ends of the U-shaped clamp due to the high heat generated during the laser processing of a long length of the clamp.

The workpiece support clamp structure of the present invention for achieving the above object is a height adjusting tool coupled to the table, a fixture for maintaining a proper distance to the height adjusting tool, a workpiece to set the position by coupling to the fixture, and the fixture In the workpiece support clamp consisting of a clamp to be fixed to the height adjustment by the height adjustment mechanism and the support piece is fixed by pressing the upper surface of the workpiece, the support for the space between the pair of support pieces of the pair of the workpiece support clamp By forming split ribs interconnecting the pieces to prevent the opening of the support piece due to the high temperature generated by laser processing, the split ribs are formed in 1/3 position of the support piece so that both ends of the support piece can be used. The basic features of the technical configuration.

The clamp structure for the workpiece support in the above-described configuration forms a support rib on the left and right sides of the clamp, but forms a split rib connecting the pair of support pieces by forming in the central space portion between the support pieces so as to laser the rectangular material. Even if machining is performed by the rib, the split rib connecting the support piece and the support piece prevents the shearing of the support piece shear of the clamp as much as possible even if high heat occurs due to laser processing. It is effective to maximize efficiency because both ends of the support piece are formed in

As shown in Figures 3 to 5, the workpiece support clamp structure of the present invention

Height adjustment tool 110 coupled to the table 100, the fixture 120 to maintain a suitable interval on the height adjustment device 110, the workpiece 130 to be coupled to the fixture 120 and set, and the In the clamp for supporting the workpiece, which is fixed to the fixture 120, the height is adjusted by the height adjusting device 110, the support piece 142 is composed of a clamp 140 for pressing and fixing the upper surface of the workpiece 130. In addition, a split rib 144 is formed in the space portion between the pair of support pieces 142 of the workpiece support clamp 140 to interconnect the support pieces 142.

The height adjusting device 110 adjusts the height of the workpiece 130 is installed by rotating the combined control plate 111.

The fixture 120 is coupled to the nut 122 having a washer to form a screw rod 121 vertically on the table 100 and fastened to the screw hole on the top.

The workpiece 130 selects an arbitrary support surface 131 on the upper side.

The most important clamp 140 in the present invention is formed in each of the support pieces 142 on the left and right, formed in the central space between the support pieces 142 split rib connecting the pair of support pieces 142 ( 143).

The present invention forms a clamp 140 by laser processing a rectangular material for accuracy and productivity, but the split rib 143 connecting the support piece 142 between the support piece 142 and the support piece 142. Since it is formed integrally, even if high heat occurs due to the laser processing, the shear shear of the clamp 140 or the long-term use to suppress the closed end of the shear to the maximum to minimize the occurrence of the defective rate.

In particular, the split rib 143 formed on the support piece 142 of the clamp 140 is formed at 1/3 of the support piece 142 so that it can be selectively used in consideration of the shape size of the workpiece 130, etc. It is very efficient to use.
