Problems solved by technology

[0003] 1. The test cannot be completed quickly. The efficiency of manually screwing in and out of the bulb is very low. It takes 10 seconds to test one.
[0004] 2. The torque value cannot be determined, because it is screwed in and out by hand, the torque value cannot be accurately judged
[0005] 3. When the test volume is large, it is easy to cause employee fatigue, and the bulb may be broken, which poses a safety hazard

Abstract

The invention discloses a screw lamp holder torsion testing device and a torque testing method thereof. The device comprises a fixing base, a connecting piece and an electric screwdriver with an adjustable torque. The fixing seat is used for fixing a screw lamp holder to be tested. One end of the connecting piece is provided with external thread. The other end of the connecting piece is provided with a groove. The electric screwdriver with the adjustable torque can be embedded into the groove. According to a set torque, the electric screwdriver with the adjustable torque screws the end of the connecting piece provided with the external thread into or out of the screw lamp holder to be tested. The torque testing method comprises the followings steps of: fixing the screw lamp holder to be tested into the fixing base; setting a torque of the electric screwdriver with the adjustable torque; embedding the electric screwdriver with the adjustable torque into the groove; placing the connecting piece into the screw lamp holder to be tested; according to the set torque, by using the electric screwdriver with the adjustable torque, and screwing the end of the connecting piece provided with the external thread into or out of the screw lamp holder to be tested. The device has the advantages of simple structure, rapid measurement, accurate torque value and no existence of a potential safety hazard.

Description

technical field [0001] The invention relates to the field of torque testing of screw lamp holders, in particular to a torque testing device and method for screw lamp holders. Background technique [0002] The torque test of lamps is based on the mandatory national standard (GB) 17935-2007 inspection standard for screw lamp holders. The threads of different screw lamp holders have different torque test requirements. The most commonly used screw lamp holders in the professional lighting industry are E27 and E40 (the letter E indicates the screw lamp holder of Edison thread, and the number after "E" indicates the integer value of the outer diameter of the lamp holder thread. The thread that the screw lamp holder matches with the lamp cap , should comply with the provisions of GB1005-67 "Threads for lamp caps and lamp holders"), E27 lamp holders are required to withstand 1.5 N.M (N.M), and E40 lamp holders are required to withstand 3 N.M (N.M) torque. The current problems in th...
