Integrated Test Device For Circular Saw Switch And Lower Guard
Standard: EN 60745-2-5: 2010 Annex M21.18, Annex M21.18.301, Annex M21.203,
Annex M21.301, figure M.301, IEC60745-2-5:2003 Annex BB.20.102, EN
60745-2-5:2010 clause 17.101 and clause 19.102.3.
Application: It is used to test the circular saw switch performance and
circular saw lower guard’s durability and recovery time.
Test sample: Circular saws
Feature: This equipment is composed of two parts, the mechanical system and
electrical control system.
Mechanical system is the table for circular saw. There are a switch
and sample socket on the table, operator can push the switch to
turn on or off the load power supply to the test sample; different
sizes of circular saws can be placed and fixed on the table; on the
table, device for locking the switch of the hand-held circular saw
in the “on” position; the blade can extend to the bottom of the
table through the middle groove; on the table where under the
blade, there are a the lower guard putter and two position sensors
, which can be drive the lower guard of the circular saw to be
opened or closed.
The electrical control system consists of the load power supply,
MITSUBISHI PLC, 7 Inch Touch screen and etc. Can achieve manual
operation and automatic operation.
