Description
Technical Field
The invention relates to the field of machine tool machining, in particular to a clamp for a numerical control machine tool.
Background
The part is machined on the numerical control machine tool, which is mainly dependent on a machining program, is different from a common machine tool, does not need to be manufactured, a plurality of moulds and clamps are replaced, and the machine tool does not need to be frequently readjusted, so that the numerical control machine tool is suitable for occasions where the machined part is frequently replaced, namely, is suitable for the production of single-piece and small-batch products and the development of new products, thereby shortening the production preparation period and saving the cost of a large amount of process equipment.
Because all high-speed rotations of digit control machine tool processing cutter, the machined part needs various anchor clamps to step up, but present lathe anchor clamps all have the atress uneven at present, or arm power overlength short is difficult to add the stable problem of holding.
Disclosure of Invention
The invention aims to provide a clamp for a numerical control machine tool, which aims to solve the problems in the background technology.
In order to achieve the purpose, the invention adopts the following technical scheme:
a clamp for a numerical control machine tool comprises an upper pressing plate, two lower pressing blocks and at least one supporting block;
the upper pressing plate is in a strip-shaped configuration, the upper pressing plate is horizontally placed above the two lower pressing blocks, two strip-shaped openings which vertically penetrate through the upper pressing plate are formed in the upper pressing plate, and two bolts vertically penetrate through the two strip-shaped openings downwards and then are screwed into the two lower pressing blocks in a threaded mode; the top of the bolt is provided with a limiting head with the caliber larger than the width of the strip opening;
the end part of the upper pressure plate is continuously chiseled with step-shaped first sawteeth along the oblique inner direction from top to bottom, the lower part of the first sawteeth at least one end is provided with a supporting block in a supporting way, and the top surface of the supporting block is chiseled with second sawteeth which are mutually matched and connected with the first sawteeth.
The lower pressing block is formed by connecting a rectangular bottom plate and a cuboid top block fixed in the middle of the upper surface of the rectangular bottom plate.
Vertical screw holes are formed in the top of the cuboid ejector block, and bottom threads of the bolts are screwed into the screw holes.
The limiting head is of a cylindrical structure.
The lower pressing block is provided with a bolt hole used for fixing the lower pressing block on a machine tool.
The rectangular bottom plate is provided with a bolt hole used for fixing the lower pressing block on a machine tool.
Compared with the prior art, the fixture has the advantages that the stability of workpiece fixing is greatly improved compared with the existing fixture through the arrangement of the upper pressing plate, the lower pressing block, the supporting block and the sawtooth connection mode.
Drawings
FIG. 1 is a perspective view of the clamp of the present invention;
figure 2 is a front view of the clamp of the present invention.
In the figure, 1, a lower pressing block, 4, a strip opening, 5, an upper pressing plate, 6, a limiting head, 9, a first sawtooth, 10, a second sawtooth, 11 and a supporting block.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 2, the clamp for the numerical control machine tool of the present invention comprises an upper press plate 5, two lower press blocks 1 and at least one support block 11;
the upper pressing plate 5 is in a strip-shaped structure, the upper pressing plate 5 is horizontally placed above the two lower pressing blocks 1, two strip-shaped openings 4 which vertically penetrate through the upper pressing plate 5 are formed in the upper pressing plate 5, and two bolts vertically penetrate through the two strip-shaped openings 4 downwards and then are screwed into the two lower pressing blocks 1 in a threaded mode; the top of the bolt is provided with a limiting head 6 with the caliber larger than the width of the long strip opening 4;
the end part of the upper pressure plate 5 is continuously chiseled with step-shaped first sawteeth 9 along the oblique inner direction from top to bottom, a supporting block 11 is supported and arranged below the first sawteeth 9 at least one end, and second sawteeth 10 which are mutually matched and connected with the first sawteeth 9 are chiseled on the top surface of the supporting block 11.
The lower pressing block 1 is formed by connecting a rectangular bottom plate and a cuboid top block fixed in the middle of the upper surface of the rectangular bottom plate.
Vertical screw holes are formed in the top of the cuboid ejector block, and bottom threads of the bolts are screwed into the screw holes.
The spacing head 6 is of cylindrical configuration.
The lower pressing block 1 is provided with a bolt hole for fixing the lower pressing block 1 on a machine tool.
The rectangular bottom plate is provided with a bolt hole used for fixing the lower pressing block 1 on a machine tool.
When the clamping device is used, two sides of the middle part of a workpiece are respectively placed on the rectangular bottom plate of the lower pressing block 1, the workpiece is clamped through the two cuboid ejector blocks, the upper pressing plate 5 is placed down at the moment, the two bolts are rotated to enable the upper pressing plate 5 to be tightly pressed above the workpiece, and therefore the middle part of the workpiece is fixed in an area surrounded by the upper pressing plate 5, the lower pressing block 1 and the two bolts. At this time, the upper platen 5 is supported at least one end, preferably both ends, by the supporting blocks 11, so that the middle portion of the workpiece is firmly fixed. Finally, the two lower pressing blocks 1 are fixed on a machine tool and then are machined by using a cutter, so that the machining process is very stable, and even though the machining of the cutter can generate torque, the supporting blocks 11 can provide torque opposite to the torque to offset the torque.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
