Abstract
A workpiece pallet is disclosed with which it is possible to machine a number of different workpieces in a transfer line with a minimum of equipment. The workpiece pallet has several faces each having at least one clamping place to receive a workpiece. The main body is rotated to present a selected side in the stations to allow operations on workpieces clamped on that side.
Claims11
A transfer line including at least one workstation having means for performing operations on one or more workpieces, a series of workpiece holding pallets, a station locating and clamping mechanism for locating and clamping each of said pallets in said station, and a transfer system including drive components adapted to engage each of said pallets and successively transfer each pallet in a transfer direction so as to successively transfer each of said pallets into said workstation, said pallets each comprising:
- a main body adapted to be engaged by said transfer system drive components, said main body having a longitudinal axis extending in said transfer direction when engaged by said transfer system drive components;
- said main body having a circumferential array of workpiece mounting surfaces distributed circumferentially around said longitudinal axis to form a generally polygonal cross sectional shape, at least one clamping fixture associated with each mounting surface for receiving and securing a workpiece thereto;
- a circumferential array of sets of transfer system and station locating and clamping mechanism engaging features on said main body separate from said clamping fixture, each set of features associated with a respective mounting surface distributed circumferentially around said longitudinal axis of said main body, each set of features adapted to be engaged by said transfer system and station drive components in respective rotated positions of said main body about said longitudinal axis thereof.
A method of palletizing any of a series of variously configured workpieces for transfer between stations in a multistation machine by a transfer system for performing operations on a selected configuration of said series of variously configured workpieces in each of said stations, comprising the steps of:
- providing clamping fixtures on each side of a polygonally shaped main body to provide a workpiece pallet, said clamping fixtures on each side of said main body each adapted to receive a respective workpiece configuration;
- rotating said main body about a longitudinal axis extending parallel to said main body sides during installation of said main body in said transfer system so as to be oriented to present the side of said main body in each station which is adapted to mount a workpiece of a particular selected configuration to be operated on;
- and
- transferring said main body through said stations with said main body in said orientation to enable said operations to be performed on said particular selected workpiece configuration.
