Abstract

PURPOSE:To provide processing of high precision by furnishing a means to press the processed portion of a work to a pallet at the top plate of a jig to fix the pallet in such a way as fronting the processing tool, and thereby preventing possible distortion at the time of processing. CONSTITUTION:At a clamping device installed in each processing station, a means 225 to press the processed portion of a work to a pallet is installed at the top plate 38a of a jig to fix the pallet in such a way as fronting the processing tool. Under processing, this pressure means 225 presses the work, which then receives the reactive force from the processing tool, and thus distortion of the work can be avoided. Here the work held on the pallet is clamped in each processing station according to the current condition of processing, so that even such a work as made of a flexible or fragile material can be firmly clamped to ensure processing in high precision.

Description

[Detailed description of the invention]

Sho J, L! This invention has a plurality of processing stations, and each processing station is equipped with a processing machine that performs a predetermined processing.
In a transfer machine, a workpiece fixed on a gutter is continuously conveyed to each processing station via a pallet using a transfer bar while being processed. The present invention relates to a clamping device that re-clamps a material according to machining conditions. -The Koreo Koji Ao transfer machine has multiple processing stations, and each processing station is equipped with a dedicated processing machine that performs the specified processing in the processing order, and the workpiece is sequentially transferred to each processing station using a transfer bar. The products are conveyed in a continuous manner, and each processing station performs predetermined processing to continuously form products. The transfer machine has two methods of transporting the workpiece from one processing station to the next processing station: one method is to directly transport the workpiece using a transfer bar, and the other is to place the workpiece on a pallet and transport it via the pallet using a transfer bar. There is. By the way, W3jF! In this case, from the viewpoint of workability, the pallet is fixed with the workpiece placed on the processing tuna pallet, and processing is performed in this state. Therefore, the pallet is equipped with one clamp txtR for fixing the workpiece. This clamp +:'i ti is generally a 4g iTh that clamps the work by firmly pressing the work from above. B-T [On the left, L-group ↓ 2, 5 times E-1, immediately hit 1 point, 11 on T, and the prepared Rizo-ump support 1 is 1.
Since the workpiece is only pressed from above, it is fine if the workpiece is extremely rigid, but if the workpiece is made of a flexible material or a stiff ladle, If the workpiece has a shape with a curved part, if the workpiece is held down from above, for example, when drilling a hole in the workpiece, the workpiece will bend due to the thrust of the drill and the hole will be drilled in that state. Because we do
There was a problem in that the workpiece returned to its original state after machining and the hole became tilted. This invention involves sequentially and secretly transporting workpieces using pallets to a plurality of processing stations arranged in the order of processing, while performing predetermined processing at each processing station. A clamping device installed in a processing station of a transfer machine that molds products, wherein a pressing means for pressing a processed part of a workpiece against the pallet is provided on the top plate of a jig for fixing a pallet, facing a processing tool. During machining, the workpiece is pressed by the pressing means to receive the reaction force of the machining tool, thereby preventing distortion of the workpiece.

l: You should be able to do some kind of processing. According to this invention, since the workpiece held on the pallet in the transfer machine is clamped at each processing station according to the processing conditions, it is possible to clamp the workpiece held on the pallet in the transfer machine according to the processing conditions. It is possible to precisely clamp the workpiece to prevent distortion during machining, making it possible to perform highly accurate machining.
