The design principle of yarn cutting machine sand line broken wire protecting equipment of the present invention is described as follows：
The applicant is special in the invention of " numerical control yarn cutting machine sand line disconnection protection circuit " filed in September in 2013 24 days
" sand line power circuit " is designed with sharp specification, by emergency stop switch SB1, sand line, working table lamp normal open switch K and workbench
The series circuit two ends that lamp TD is formed are connected to a secondary coil terminal 26 of node 41 and single phase poaer supply transformer T
Between, once sand line broken string, then just lose in the node 41 and out-secondary four series circuits in parallel between 26
AC power, then can make cooling pump three phase alternating current motor M1, shelf up and down reciprocatingly three phase alternating current motor M2, grease pump blow-up
Stream motor M4 and sand line rotary direct current electric motor M3 lose power supply and out of service, so as to after sand line broken string, cut to sand line
Cutting mill plays a protective role, and after the sand line of broken string is connected, makes above-mentioned each motor obtain electric, then yarn cutting machine can not be by former journey
Sequence proceeds work piece cut processing, without damaging workpiece to be machined.
In order that sand line obtain it is electric after run well, then in addition to above-mentioned numerical control yarn cutting machine sand line disconnection protection circuit,
The specific yarn cutting machine sand line broken wire protecting equipment of the energization that is in series with sand line two ends respectively should be also designed, it includes bow
The conductive assembling device structure of the conductive assembling device structure of frame upper arm and shelf underarm, the shelf upper arm and shelf underarm it
Be cascaded with sand line upper and lower ends respectively after, then be connected in sand line power circuit, sand line is normally transported when obtaining electric
OK, out of service after dead electricity, upper end is in series the upper lead on upper lead packing ring with " sand line power circuit ", and lower lead packing ring
On lower lead be in series with " sand line power circuit " lower end, respectively by shelf upper arm conduction assembling device structure and shelf under
Arm conduction assembling device structure is in series with sand line upper end and sand line lower end.The conductive assembling device structural circuit road of above-mentioned series connection
Footpath is described as follows：
Shelf upper arm conduction assembling device structural circuit path is as follows：
The upper inner nut of conduction, upper lead packing ring and upper outer nut are sleeved on the upper copper spiral shell of brass screw with being sequentially connected
On nail external screw thread, the inner upper brass screw inner face of upper brass screw is mutually crimped with the upper spacer ring collar wall of the upper spacer ring of conduction, on
Spacer ring is pressed on upper arm under ball bearing and upper arm between ball bearing again, makes ball under ball bearing on upper arm, upper spacer ring and upper arm
Bearing three mutually crimps conduction, and ball bearing outer ring is connected by ball bearing steel ball on upper arm with ball bearing inner race on upper arm on upper arm
Conduction is touched, equally, ball bearing outer ring passes through ball bearing steel ball and ball bearing under upper arm under upper arm under the upper arm of ball bearing under upper arm
Inner ring contacts conduction, and ball bearing inner race is sleeved on the upper axle of upper arm bearing inner sleeve under ball bearing inner race and upper arm on upper arm
Hold on outer wall of inside race so as to conductive, the upper bearing (metal) outer wall of inside race of upper arm bearing inner sleeve is connected as one with upper bearing (metal) inner sleeve flange face
Body is conductive, because the upper grip loop port end face of upper grip set is in close contact with the upper bearing (metal) inner sleeve flange face of upper bearing (metal) inner sleeve,
The upper grip loop port end face for then covering upper grip is conductive, and the upper grip lower end outer wall because of upper grip, upper grip middle part outer wall
It is installed in the upper grip set lower end endoporus of upper grip set with upper grip upper end outer wall, then makes outside the upper grip lower end of upper grip
Wall, upper grip middle part outer wall and upper grip upper end outer wall are conductive, and the sand line upper end of sand line is installed in upper grip lower end
In the upper grip lower end sand line clamping slot of upper grip lower end outer wall, therefore make sand line upper end conductive, after sand line broken string, upper lead electrical pad
Circle then makes sand line power circuit power-off with regard to dead electricity, and sand line machine is out of service.
Shelf underarm conduction assembling device structural circuit path is as follows：
The lower outer nut of conduction, lower lead packing ring and lower inner nut are sleeved on the lower copper spiral shell of lower brass screw with being sequentially connected
On nail external screw thread, the inner lower brass screw inner face of lower brass screw is mutually crimped with the lower spacer ring collar wall of the lower spacer ring of conduction, under
Spacer ring is pressed on the underarm of conduction under ball bearing and underarm between ball bearing again, make ball bearing on underarm, lower spacer ring and under
Ball bearing three mutually crimps conduction under arm, and ball bearing outer ring is by ball bearing on ball bearing steel ball on underarm and underarm on underarm
Circle contacts conduction, equally, under underarm under the underarm of ball bearing ball bearing outer ring by under ball bearing steel ball under underarm and underarm
Ball bearing inner race contacts conduction, and ball bearing inner race is sleeved under lower chuck set under ball bearing inner race and underarm on underarm
In the collar wall of chuck upper end so as to conductive, and under the lower chuck upper end outer wall because of lower chuck, lower chuck middle part outer wall and lower chuck
End outer wall is installed in the lower chuck set lower end endoporus of lower chuck set, then make lower chuck upper end outer wall, the lower chuck of lower chuck
Middle part outer wall and lower chuck lower end outer wall are conductive, and the sand line lower end of sand line is installed in the lower chuck lower end of lower chuck lower end
In the lower chuck lower end sand line clamping slot of outer wall, therefore sand line lower conductive is made, after sand line broken string, lower lead packing ring just loses
Electricity, then make sand line power circuit power-off, and sand line machine is out of service.
This yarn cutting machine sand line power-off protection apparatus advantage is compact conformation, when sand line breaks, can ensure that makes sand
The instant dead electricity of line electromechanics source circuit, conversely, after sand line is connected, sand line can be made to obtain from power circuit electric and make sand line machine normally transport
Turn.
