Description
Technical field
The utility model relates to mechanical structure field, particularly a kind of hand-held lock screw instrument and send lock screw machine containing this instrument.
Background technology
The mode of tightening screw at present has tightens and uses automatic locking screw machine to tighten two kinds of operations by hand.Tighten by hand and comprise pure craft and tighten and tighten two kinds with power screw cutter or pneumatic screw cutter, the latter produces rotary power by electronic or pneumatic mode, to replace frequent manual tightening action, alleviate the working strength of lock screw to a certain extent, but because manual placement screw and alignment screw head still need to take a large amount of working times and energy, therefore whole efficiency promotes more limited.For promoting the operating efficiency of lock screw, have developed in the industry automatic locking screw machine, automatic locking screw machine also known as automatic screw transfering machine, automatically send lock screw machine, industrial tightening system, screw locking machine device people etc., is replace the machine that traditional-handwork tightens screw.
Traditional Handheld automatic locking screw machine as is illustrated by figs. 11 and 12, comprise an extension sleeve (10), screw is first blown in screw chuck (9) by feeding channel (90), artificial hand-held tools for alignment screw hole presses down, batch bar (2) be arranged on screw cutter rotates and presses down and withstands screw thus lock-screw, after completing, extension sleeve resets under the effect of spring (11), and screw is blown into screw chuck again, so circulates.But there is following shortcoming in it:
1. the elastic force that artificial lower press tool will overcome spring in extension sleeve could be compressed, thus screw operation is locked in having pressed down of realization batch bar, and the operation of thousands of times every day, labour intensity is high.
2. in order to reduce labor intensity, the dynamics of spring is smaller, after extension sleeve ejects after lock end screw, next screw can be blown in screw chuck, but the elastic force of spring is little or have other the reasons such as friction, sleeve does not likely have ejection and puts in place, and the transfer passage causing batch pole spacing to live screw causes batch bar and screw to block in chuck, causes fault.
3., because screw is ensconced in chuck or it is shorter to stretch out chuck, artificial handheld tool will aim at screw hole position difficulty, and once do not aim at, screw can be retracted in screw chuck, causes contraposition more difficult.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of screw easily to aim at screw hole, simple to operate, labour-saving a kind of hand-held lock screw instrument.Another object of the present utility model is to provide a kind ofly send lock screw machine containing a kind of hand-held lock screw instrument.
