Spacer block of vice

Abstract

The present invention relates to a spacer block for keeping adjacent workpieces spaced from each other when fixing a plurality of workpieces to a vise. It can flexibly respond to the dimensional differences and presence or absence of each workpiece, and fix multiple workpieces in their own inherent positions. The spacer block of the present invention has a slide table (1) guided in the gripping direction of the vise. The driving wedge (8) that is formed with the driving wedge surface (9) on the two outward faces is fitted on the guide protrusion that is erected on the sliding platform, and the driving wedge is provided with the direction in which the driving wedge is erected in the direction of the guide protrusion. The advancing and retreating device (11) of advancing and retreating. A pair of jaw washers (14) with a driven wedge surface (13) slidingly contacting the wedge surface are arranged on both sides of the drive wedge. In addition, a return spring (18) is provided to bias the pair of jaw spacers in a direction to approach each other. The driving wedge surface (9) and the driven wedge surface (13) are preferably formed as multi-stage wedge surfaces in which a plurality of wedge surfaces are arranged in a stepped shape.

Description

technical field [0001] The present invention relates to a spacer block for keeping adjacent workpieces at a distance from each other when fixing a plurality of workpieces to a vise (work vice) fixed to a machine tool table. Background technique [0002] When machining multiple workpieces of the same shape with other machine tools such as machining centers, it is more efficient to fix multiple workpieces on the table and process them at the same time. In order to fix multiple workpieces on the workbench, the vise is fixed on the workbench, and one or more spacers are arranged between the opposite jaws of the vise, and between the spacer and the jaws and the spacer The method of inserting and fixing workpieces between each other (when multiple spacers are configured) has been widely adopted (for example, Japanese Patent Publication No. ). [0003] When fixing a long and slender workpiece on the table, in order to prevent the workpiece from bending due to the machining reacti...

Problems solved by technology

[0007] However, when machining slender workpieces, a large table is required for fixing the workpieces, so the machine tools used are also large

In addition, in the method of fixing the workpieces one by one on the table for processing, the loading and unloading time of the workpieces is longer compared with the actual processing time of the workpieces, which reduces the working efficiency of the machine tool.

That is, use of large equipment with lower work efficiency, resulting in higher processing costs

In addition, the workpiece must be loaded and unloaded frequently, so the workload increases, and the operator cannot perform other operations during the machining process.
