The machine tool workbench 10 belongs to an accessory part of a vertical milling machine, when milling of a workpiece is carried out, the workpiece 20 is placed on the machine tool workbench 10, is supported and connected through an auxiliary clamp by means of an inverted T-shaped clamping groove 10a, is vertically pressed on the surface of the machine tool workbench 10 from the top surface of the workpiece and is fastened, and milling is realized by contact of a cutter and the surface of the workpiece.

There is the problem of processing interference in order to solve present centre gripping mode to workpiece surface, the utility model discloses a set up the lateral wall that side strutting arrangement fastened the support centre gripping to the work piece to the centre gripping of eliminating the work piece milling face is interfered. As shown in fig. 5, the side supporting means includes a fastening member connected to the inside of the inverted T-shaped clamping groove 10a, and a clamping member horizontally and laterally abutted against the side wall of the workpiece 20 placed on the machine table 10 is provided on the fastening member.

Specifically, as shown in fig. 5, the fastening component is a sliding pulling plate 1 which is arranged in the inverted T-shaped clamping groove 10a in a limiting manner, a fastening bolt 2 which extends out of the inverted T-shaped clamping groove 10a vertically penetrates through the sliding pulling plate 1, and the clamping component is sleeved on the fastening bolt 2 and attached to the surface of the machine tool workbench 10. When the clamping device is operated, the fastening bolt 2 is rotated, so that the sliding pull plate 1 is tightly attached to the inner top surface of the inverted T-shaped clamping groove 10a, meanwhile, the fastening bolt 2 tightly presses the clamping part on the surface of a workbench 10 of the machine tool, in the fastening state, the clamping part is tightly contacted with the side wall of a workpiece to tightly press and fasten the workpiece from the side direction, and meanwhile, the side supporting device is also arranged on the other side of the workpiece to tightly support and tightly fasten the workpiece from the two sides.
