With the higher limit and lower limit of pressure sensor, when the action that presses starts, institute's displacement sensors and pressure sensor measure
Terminal distance and terminal pressure send to the master controller, be compared by detection unit, in displacement, pressure
Limit value or the product of lower limit are set as defective products, and mark, and are otherwise non-defective unit.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
1. the utility model, by first, second section of stroke controlling unit of setting, the displacement and pressure to gas and oil cylinder are real-time
Detection and control, especially in second segment stroke controlling unit, terminal distance just performs displacement deceleration after being less than 1mm, is less than
Riveted joint is fallen naturally after 0.3mm, and after terminal distance reaches the terminal of setting, return resets immediately, and control in advance is slowed down, and is kept away
It is excessive to exempt from hydraulic coupling, the problem of causing workpiece to be forced through, thereby may be ensured that repeatable accuracy in ± 0.04mm, meets aluminium vehicle body
Requirement of the manufacturer to positional precision；
2. by setting detection unit, coordinate with pressure sensor and displacement transducer, when the pressure or terminal that detect
When distance is beyond the upper limit value and lower limit value of setting, then judges that the product for defective products, is detected, be considered as non-defective unit without departing from scope, from
And automatic detection is realized, meet requirement of the aluminium vehicle body manufacturer to riveting character surveillance.
