The contact hole edge of the inner hexagon bolt hole of the movable pressing plate and the inner hexagon bolt is of a concave spherical structure.

The side-ejection clamp can be used in combination by a plurality of pieces, and the clamp is placed in a T-shaped groove of a machine tool and is close to the edge of a workpiece, so that the pressing action can be realized.

The utility model has the advantages that: 1. the device is suitable for being applied to a common horizontal milling machine, a vertical numerical control milling machine and a vertical machining center, and a flat plate workpiece is fixed on a working table of a machine tool through the combined application of a plurality of clamps, so that the flatness of the workpiece can be well ensured, the deformation of the workpiece is reduced, and the deformation is not constrained by the size of the workpiece in the machining range of the machine tool. 2. The positioning precision can completely meet the processing requirement, the workpiece is clamped rapidly, the clamping force is stable, the problem that the flat tongs cannot clamp large-scale flat workpieces is solved, and the problem that the traditional pressing plate interferes with a cutter in the processing process is avoided. 3. Because the inner hexagon bolt compression surface is of a spherical structure, slight position deviation generated in the process of compressing the workpiece by the movable pressing plate can be well regulated. 4. The T-shaped base is adopted, the movable pressing plate is in pressure connection, the structure is simple, and the installation is convenient; can be combined and applied by a plurality of clamps, and has strong adaptability.

Embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.

Detailed Description

Referring to fig. 1-7, the part names are as follows: t type base 1, L type stand 2, movable clamp plate 3, connecting pin 4, sphere structure 5, hexagon socket head cap screw hole 6, hole edge 7, hexagon socket head cap screw 8, movable clamp plate front end face 9, work piece 10.

Referring to fig. 1-7, a side top clamp for processing a flat plate part comprises a T-shaped base 1 capable of being inserted into a T-shaped groove of a machine tool workbench, wherein the T-shaped base 1 is connected with the machine tool workbench, and the T-shaped base 1 is of a strip shape and is a clamp main body. An L-shaped upright post 2 is arranged on one side of the T-shaped base 1, a movable pressing plate 3 is transversely clamped between the upper parts of the L-shaped upright posts 2, and the upper parts of the L-shaped upright posts 2 are fork frame structures, namely, the upper parts of the L-shaped upright posts are open to form a middle groove. The movable pressing plate 3 is connected with the L-shaped upright post 2 through a connecting pin 4 (connecting shaft) which is transversely inserted, and the movable pressing plate 3 can be lifted up and put down to rotate around the connecting pin 4. The front end of the movable pressing plate 3 is provided with a fastening bolt which downwards penetrates through the movable pressing plate 3, and the bottom end of the fastening bolt can prop against the upper surface of the T-shaped base 1. If the processed flat plate type part is placed on the T-shaped base 1, the bottom end of the fastening bolt can prop against the processed flat plate type part.
