Abstract
Abstract A structure for the rigidification of multiple station machine tools to increase accuracy of machining operations on workpieces moved intermittently on pallets to registry stations where machine tools move toward and away from the work. The machine tools and registry stations are mounted on a common base well below the axis of the machine tool movement. Means are interposed directly between the registry stations and the tool mounts on an axis in close proximity to the axis of the machine tool movement to rigidify the relationship between the tool mount and the registry stations and thus reduce the interfaces joining the two and the possibility of motion when tool pressure is applied to the work.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
In a multiple station transfer machine in which workpieces are located and clamped in pallets and in which said pallets are sequentially moved on rails from station to station to be located on registry means at each station independent of said rails and in which each working station comprises: 1. base means, 2. registry means rigidly mounted on said base means and adapted to support, locate, and clamp a pallet in a fixed position, and 3. tooling means mounted on said base means and adapted to feed tools on a first axis into said workpiece supported on a pallet and in turn on said registry means, that improvement which comprises a direct, positive, in-line connection means extending between and rigidly connecting said registry means and said tooling means on a second axis in close proximity to said first axis and exclusive of the indirect connection therebetween through said base means, said in-line connection means being structured to transmit compression and tension forces between said registry means and said tooling means.
Claim 2
Dependent Claim
170 words
In a multiple station transfer machine in which workpieces are located and clamped in pallets and in which said pallets are sequentially moved on rails from station to station to be located on registry means at each station independent of said rails and in which each working station comprises: 1. base means, 2. registry means rigidly mounted on said base means and adapted to support, locate, and clamp a pallet in a fixed position, and 3. tooling means mounted on said base means and adapted to feed tools on a first axis into said workpiece supported on a pallet and in turn on said registry means, that improvement which comprises a direct, positive, in-line connection means extending between and rigidly connecting said registry means and said tooling means on a second axis in close proximity to said first axis and exclusive of the indirect connection therebetween through said base means, said in-line connection means being structured to transmit compression and tension forces between said registry means and said tooling means.
Claim 3
Dependent Claim
245 words
In a multiple station transfer machine in which workpieces are located and clamped in pallets and in which said pallets are sequentially moved from station to station along rails to registry means at each station and in which each working station comprises: 1. base means, 2. registry means fixedly mounted on and above said base means and adapted to vertically support a work supporting pallet and locate and clamp the pallet in a fixed position independent of said rails and in a generally horizontal plane, and 3. tooling means comprising a slide base mounted on and above said base means in laterally exposed relation to said registry means and tool means slideably supported on said slide base and adapted to feed tools on a first generally horizontal axis toward and away from a workpiece supported on said pallet and in turn on said registry means, that structural improvement which comprises means forming a contiguous substantially direct, positive in-line structural connection means which extends laterally between and is rigidly connected to said registry means and said slide base on an axis spaced above said base means in close proximity to said first axis said connection means being structured to transmit both compression and tension forces between said registry means and said slide base, wherein said connection means is rigidly connected at one end to the upper portion of said registry and is rigidly connected at the opposite end to the upper portion of said slide base.
Claim 4
Dependent Claim
