Survey the relatively reliable safety of plant running.Cohesion device 3 includes opening annulus and locking member, the T-shaped structure of locking member, and bottom is to fall
T-shaped piece put, T-shaped piece of upper end sets two pieces of elastic plates being parallel to each other, this two ends of two pieces of elastic plates respectively with opening annulus
It is connected, and positioning hole is offered on two pieces of elastic plates, opening annulus is each passed through on two pieces of elastic plates by clamping screw
Positioning hole and the mode of fixation are held tightly in the periphery of crossover sub 4.The bottom of cohesion device 3 passes through the connected sliding block 15 of screw, the sliding block
15 reciprocatingly slide along the guide rail for being arranged at the lower section of leading screw 1 and being parallel to each other with leading screw 1, and then drive cohesion device 3 with silk
Thick stick 1 is for linear motion, reduce by cohesion device 3 conduct oneself with dignity caused by influence to force snesor 5.In addition, the side of sliding block 15 is also set
There are two travel switches 14, for controlling stroke compared with zero-sum, when unexpected situation occurs in computer control system, it would however also be possible to employ
Manual control mode realizes the control to the stroke of push rod 6, it is to avoid the generation of contingency, has further ensured the detection means
Use safety coefficient.Specifically, the travel switch 14 close to hasp installing mechanism side, which is mainly used in control push rod 6, stops it
Advance, the travel switch 14 close to the side of linear stepping motor 2, which is mainly used in control push rod 6, makes it stop retreating.
In addition, the present embodiment also includes SBR linear sliders 7 and the sliding block base 13, SBR for fixing SBR linear sliders 7
Linear slider 7 is used for by push rod 6, plays supporting role, reduce by push rod 6 conduct oneself with dignity caused by influence to force snesor 5, carry
The precision of high detection result.In the linear stepping motor 2, guide rail, sliding block base 13 and hasp installing mechanism of the present embodiment
Baffle plate 10 be fixedly installed in installation pedestal 16, installation pedestal 16 is supported and is fixed on above the ground by four pillars,
And through hole is offered at the position relative with hasp 9 to be measured of hasp installing mechanism side in installation pedestal 16, for leading to
The balancing weight 12 for being hung on the lower section of hasp 9 to be measured is crossed, using balancing weight 12 primarily to simulating hasp 9 to be measured in children's safety
Load on seat under wear condition.
During work, start linear stepping motor 2 first, the driving leading screw 1 of linear stepping motor 2 is for linear motion, and leading screw 1 is passed through
Crossover sub 4 promotes force snesor 5 to advance, and then promotes the advance of push rod 6 to withstand hasp 9 to be measured, applies active force and opens to be measured
Hasp 9, while balancing weight 12 drops, now force snesor 5 shows the opening force of hasp to be measured 9 collected simultaneously through secondary meter
It is sent to computer and carries out data processing, and then judge whether hasp 9 to be measured is qualified, if it is determined that being unqualified, needs to add again
Work, if it is determined that being that qualified then continuation detects next hasp 9 to be measured.
A kind of hasp opening force on-line measuring device of the present invention, is substituted existing using the type of drive of linear stepping motor 2
Manual-pushing push rod open hasp operation, substantially reduce hand labor intensity, and effectively improve operating efficiency；Passed using power
Sensor 5 substitutes artificial reading, by the hasp opening force size collected shown through secondary meter and be sent to computer carry out exist
Line is detected, not only reduce further hand labor intensity, the result of detection is also relatively reliable, accurate.Production can be met completely
The requirement of quality secure context.
Schematical above that the present invention and embodiments thereof are described, the description does not have restricted, institute in accompanying drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited thereto.So, if the common skill of this area
Art personnel are enlightened by it, without departing from the spirit of the invention, are designed and the technical scheme without creative
Similar frame mode and embodiment, all should belong to protection scope of the present invention.
