Claims

[Claims for Utility Model Registration] 1. A pallet 40, which is provided in an annular shape with a space formed in the lower center of the pallet 40, and has a plurality of positioning portions on its lower surface and a plurality of engagement portions on its inner periphery. a clamped member 44, a pallet clamp body 25 serving as a base for fixing the pallet 40; , a positioning member 39 for determining the position of the positioning portion of the member to be clamped 44; and a positioning member 39 provided within the pallet clamp body 25,
A cylindrical body 16 that is fixed to the pallet clamp main body 25 and has a cam groove 17 formed on its outer periphery; and a plurality of clamped members 44 that are fitted onto the cylindrical body 16. clamp bodies 19, 20 forming a plurality of engaging parts on the upper and lower outer peripheries in order to engage with the engaging parts of the cylindrical body; 17, and the driving body 2
2 and 24, the clamp body 1
As 9 and 20 move up and down, this clamp body 1
9 and 20, and when the driving bodies 22 and 24 are raised, the clamping body 1 is connected to the engaging portion of the clamped member 44.
As the engaging portions 9 and 20 rise, they reach a rotational position where they can pass, allowing the pallet 40 to be separated from the pallet clamp body 25, and when descending, the clamp body is moved against the engaging portion of the clamped member 44. A pallet clamp device characterized in that, as the engaging portions 19 and 20 descend, the pallet 40 is pressed and clamped to the pallet clamp body 25 to a rotational position where the pallet 40 can be engaged. 2. In claim 1, the member to be clamped 44
and the positioning member 39, the pallet clamping device is characterized in that it is provided with a close contact confirmation means 34 for confirming close contact between both the positioning parts and the positioning member 39. 3. According to claim 1 or 2, by supplying air to the space of the clamped member to increase the internal pressure, cutting fluid and chips are prevented from entering through the uneven positioning portion between the clamped member and the positioning member. A pallet clamp device characterized by being equipped with dustproof means. 4. In claim 1, a clamp detection rod 31 is movably inserted into a through hole 30 passing through the center of the shaft 19 and one end of which is engaged with the clamp shaft 19, and the other end of the clamp detection rod 31 is prevented from moving. A pallet clamping device for a machine tool consisting of a detection sensor 76 for detection.
