Abstract
Abstract The present invention relates to a work pallet changer which changes a work pallet (4) fittet on the pallet fixing decive (2) on the table (1) of a machine tool (M), comprising movable mounting parts (12a), disposed on a rotary carrier which is rotatable about a horizontal axis (16a), to allow transferring a work pallet between a pallet mounting part located on the top surface of said rotary carrier and the pallet fixing device, and at the same time, letting chips produced by cutting fall down from a work pallet which faces downwardly.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
111 words
A work pallet changer for use with a machine tool which has a table (1) adapted for the accommodation of work pallets (4), the changer comprising a shift system which includes a plurality of pallet-mounting parts each of which can be moved between a pallet-changing position (X), suitable for the transfer of a pallet to or from the table, and another position (Y) displaced from the pallet-changing position, characterised in that the shift system comprises a rotary carrier (12) which is rotatable about a horizontal axis (16a) and has a plurality of pallet-mounting parts (12a) each adapted for holding a pallet, these parts being spaced around the periphery of the carrier.
Claim 2
Dependent Claim
