1. Overview

DB-30 Type Power-driven Gauge Length Meter (Power-driven Striking Point Machine) is the special equipment which is designed and made according to stipulation in national standard GB/T228-2002. This machine adopts high-precision ball screw to locate correctly and uses import transducer to collecting rotation signal to drive high-frequency electromagnet to strike point synchronously. Gauge length is correct, high-efficient and easy to operate. It’s the necessary matching equipment for labs.

2. Main technical parameters:

Max. gauge length: 300mm

Interval: 5mm or 10mm (adjustable)

Power source: 220V, 50HZ

Power of motor: 10W

Outline size (L×W×H): 460mm×315mm×450mm

Weight: 25Kg

3. Working principle

This equipment use micro-motor as the power, through drive high precision ball screw rotation synchronously, thus promote the punch movement horizontally .Screw rotated every circle (or half circle), impact needle marching 10mm (or 5mm), meanwhile sensors to collect a signal and drive the high-frequency electromagnet with impact needle for dotting. Motor continuous operation and can continuously dot 60 (5mm) or 30 (10mm). Such driving struck way has no special requirement to screw speed whether uniform. It can also ensure the precision of gauge length even if the rotation speed is uneven.
