Description

GERMAN

The invention relates to a device for clamping and conveying workpieces, which be processed in particular in an automatic machine flow series. In large-scale production several work steps of a workpiece carried out in a machine flow series in which each machine is operated by a worker and the workpieces are transported by hand or by lifting equipment will. The equipping of these systems with automatic workpiece conveying devices at the same time Adaptation to the work cycles of the individual machines results in automatic machine flow series.

There are two options for transporting the workpieces. Either the workpiece slides directly on a track from one station to the next, or it is clamped in a device, which holds it as a workpiece carrier during its passage through the entire flow row. This Workpiece carrier or carriage slides on rollers or rails through the production line and is attached each processing machine is determined in its position and clamped. The carriage of the wagons with the clamped workpieces is generally carried out by a push rod, which the workpiece carrier captured by the driver and pushes on.

In the known designs of workpiece carriers, the guide elements are on the underside or provided in the lower area of the side walls of the workpiece carrier.

However, this arrangement has the disadvantage that chips, which arise during machining, on the Guide rails come to rest and hinder the movement of the workpiece carriers.

We have therefore switched to working flutes into the guide rails at certain intervals, which take up the chips on the rails by moving the workpiece carriers and derive. This measure as well as the prismatic shape of the rail with sharply sloping guide surfaces with the tip at the top, however, it cannot be prevented that Chips get between the sliding surfaces or rollers of the workpiece carriers and the rails; Such chip deposits lead to increased wear of the guide elements and can cause There are disruptions in the production process.

The invention eliminates this disadvantage in that the guide elements as well as from a push rod existing drive of the workpiece carrier above the machining points of the cutting Tools are arranged. In machine tool construction, especially for copy lathes With high cutting performance, it is common to place the support guides above the machining level Workpiece carrier

to arrange. One was forced to take this measure in order to divert the chips downwards unhindered and to create space for the large amount of chips produced by these machines.

A suggestion for the proposed arrangement of the guide elements and the drive for conveyance however, the workpiece carrier in automatic machine flow lines from processing station to processing station cannot be removed from these constructions will.

An exemplary embodiment according to the invention is described below, specifically shown in the drawing a part of the transport path of a workpiece carrier according to the invention in a spatial representation.

The workpiece carrier 1 is box-shaped and has openings on all sides for the entry of the machining tools. The chips essentially fall through the lower ¹ passage 2 and are removed in the usual way by a conveyor belt or a vibrating chute. In the side wall part 4, 4 ', two rollers 5, 5' are mounted on each side of the workpiece carrier, which run on the guide rails 6, 6 '.

The device can also be guided in any other known manner.

In the exemplary embodiment shown, the workpiece carrier 1 is conveyed from one processing station to the next by the push rod 7, which is arranged next to it at approximately the same height as the rollers 5, 5 '. For this purpose, the push rod 7 first executes a rotary movement, the drivers 8 engaging between the lugs 9, 9 'of the catch 10 and thus pushing rod and work-

Couple the piece carriers together. Thereupon, at a given point in time, the lifting rod moves axially and pushes the workpiece carrier on to the next processing station.

After the shift, the push rod is turned back and again, releasing the driver Moved back to their starting position after the workpieces have been processed on the individual Machines to repeat the transport movement.

Claims (1)

Claim: Workpiece carriers for conveying workpieces, in particular for processing in automatic machine flow lines (transfer lines), whereby the device is guided sliding or rolling (in roller or prismatic guidance) on rails, characterized in that the guide elements (5j 6 and 5 ', 6') as well as that of a push rod ( 7) existing drive of the workpiece carriers are arranged above the processing points of the cutting tools.
