Claims

[Scope of claims for utility model registration] 1. Base plate 1 that can be freely moved in and out on table T of automatic machine tool M.
A positioning part 2 for positioning the table T in the front-rear direction and left-right direction by a positioning device, a fixed part 3 for fixing to the table T by a fixing device F, and a workpiece mounted on the base plate 1. A workpiece fixing surface 4 for fixing the workpiece W is provided, and the workpiece fixing surface 4 includes an X-axis reference frame 5 that receives the workpiece W at a predetermined position in the X-axis direction, and
An X-axis through T-shaped groove 7 running in the X-axis direction is fixed to the Y-axis reference frame 6 that receives the workpiece at a predetermined position in the Y-axis direction.
and a Y-axis T-groove 8 running in the Y-axis direction, and an X-axis lamp 9 placed on the workpiece fixing surface 4 is inserted into the X-axis T-groove 7 via an By engaging the X-axis locking tool 10 so as to be slidable in the
The Y-axis ramp 9 is configured to be fixable to the workpiece fixing surface 4, and the Y-axis ramp 11 placed on the workpiece fixing surface 4 is inserted into the Y-axis T-groove 8 via the Y-axis locking tool 12. The Y-axis ramp 11 is configured to be fixed to the workpiece fixing surface 4 by engaging the Y-axis locking tool 12 so as to be slidable in the direction, and fixing the Y-axis ramp 11 to the workpiece fixing surface 4. A feature is that the workpiece W is fixed to the workpiece fixing plate 1 with the X-axis and Y-axis surface clamps 9 and 11 while in contact with the frames 5 and 6 and aligned in the X-axis direction and the Y-axis direction. A workpiece fixing plate for large workpieces of automatic machine tools. 2. Scope of Utility Model Registration In the workpiece fixing platen for large workpieces of an automatic machine tool described in paragraph 1, the upper surface 14 of the main body 13 of the X-axis/Y-axis surface clamps 9 and 11 is placed on the workpiece clamp space side. Lower stage surface 14b and upper stage surface 14a on the opposite side
and a diagonally upward tightening slope 14C continuous with the upper and lower stepped surfaces 14a and 14b, and a clamp claw 23 is disposed above the lower step surface 14b, and a passive surface is slidably exposed to the tightening slope 14C. The clamp claw 23 is provided with a slope 24 and a floating fitting part 25 that allows the clamp claw 23 to move freely in the clamping direction, and a double-acting cylinder oriented in two axial directions is provided below the lower surface 14b in the main body 13. 26 is provided, and this cylinder 26
The tightening rod 2B inserted into the loose fitting part 25' is connected to the piston 27 inserted therein, and the spring 3o for temporary tightening is inserted into the upper pressure receiving chamber 29a of the cylinder 26.
By filling the lower pressure receiving chamber 29b with pressure fluid, the piston 27 and the tightening rod 28 are raised against the spring 30 by the internal pressure of the lower pressure receiving chamber 29b, so that the clamp can be released. With the pressure fluid removed from the pressure receiving chamber 29b, the piston 27 and the tightening rod 2 are
Tighten the clamp claw 23 through the passive double slope 14C.
The workpiece W is temporarily fixed to the workpiece fixing platen 1 by tilting downward in the direction of inclination of the workpiece 24, and then the upper pressure receiving chamber 29a is filled with pressure fluid to permanently fix the workpiece W to the workpiece fixing platen 1. It is configured as follows. 3. In the work fixing platen for a large workpiece of an automatic machine tool described in paragraph 1 or 2 of the claims for utility model registration, The light rain clamps 9 and 11 are provided with height reference surfaces 14b and 14d for receiving the downward surface of the workpiece W on the respective workpiece clamp space sides.
