Claims

[Scope of Claim for Utility Model Registration] 1. A clamp chamber 2 is provided in an underframe 1 of a machine tool, and a clamped portion 4 provided on the underside of a pallet 3 is placed in the clamp chamber 2 on the upper surface of the underframe 1. The insertion port 5 to be inserted is opened, a clamper 7 for clamping the clamped part 4 is provided in the clamp chamber 2, a supply path 8 for dust removal fluid is communicated with the clamp chamber 2, and the clamping is performed through the supply path 8. In a chip dust prevention device for a pallet clamp section of a machine tool configured to blow out dust removal fluid supplied to a chamber 2 from an insertion port 5, a lid lifting means 10 is provided in the clamp chamber 2, and the lid lifting means 10 A dust-proof lid 11 is supported on the upper part of the pallet 3, and the dust-proof lid 11 is lifted by a lifting means 10 to a dust-proof raised position where it closes the insertion opening 5, and a part to be clamped 4 of the pallet 3 against the lifting means 10.
The dust-proof cover 11 and the insertion opening 5 are configured to be able to switch between a lowered evacuation position in which the lid is pushed down and retracted into the clamp chamber 2, and a dust-proof lid 11 and the insertion opening 5 are located in the dust-proof raised position.
A chip dust prevention device for a pallet clamp part of a machine tool, characterized in that a dust prevention fluid blowout path 12 is formed between the mouth edge of the machine tool. 2. A pallet receiver 6 is formed on the upper surface of the underframe 1 around the insertion opening 5, and the dust-proof fluid is supplied to the clamp chamber 2 on the outer peripheral surface of the dust-proof lid 11.
2. The chip dust prevention device for a pallet clamp portion of a machine tool according to claim 1, further comprising a dust prevention fluid guide surface (11a) that redirects the dust to the outside laterally as the fluid flows upward from the inside. 3. The dust-proof lid 11 is formed with a turning drive flow path 13 that slopes upward from below, and the dust-proof lid 11 is driven to turn by the reaction force of the dust removal fluid flowing through the flow path 13 to the outside of the insertion port 5. A chip dust prevention device for a pallet clamp portion of a machine tool according to claim 1 or 2, characterized in that it is configured as follows.
