Digital display module device of rivet/nut gun

Abstract

The invention discloses a digital display module device of a rivet / nut gun, which comprises a rivet / nut gun body and a digital display module device. The device comprises a power supply device, a pressure sensor, a central processing unit, a display, an input device, a position sensor and an alarm device. Air pressure or oil pressure in the rivet / nut gun body and moving position of a piston element are sensed; and pressure, pull, hyper-pressure maximum pressure value and accumulated working times are displayed on the display through logical operation program modules of pressure, pull, counting, hyper-pressure and stroke abnormality alarm, metering unit conversion and the like of the central processing unit. Therefore, a user can determine whether the current pull is enough to deal with a rivet or a nut to be pulled in time under the safe operating condition, and the device provides alarm under the abnormal condition.

Description

technical field [0001] The invention is a technical field applied to riveting tools such as rivets and caps, especially a digital display module device, which can instantly display the working air pressure or oil pressure value, pulling force value, working air pressure or Whether there is an abnormal overpressure in the oil pressure, the overpressure pressure value used, the accumulated total number of times of use, and whether the piston stroke is insufficient to detect whether maintenance and inspection or replacement of the leak-proof element is required, and when the number of times of use reaches the number of maintenance and repair times, it will give a warning pneumatic , Oil pressure or air / oil pressure linkage pull nail / cap pull gun. Background technique [0002] The most important thing in the use of various rivet / cap pullers is the ability of the tool to pull the rivet and the stroke of the rivet. Among them, the ability of riveting has an inseparable parameter ...

AI Technical Summary

Problems solved by technology

Since the air pressure or oil pressure supplied at the job site will change at any time, it is impossible for the user to know the size of the air or oil supply pressure and what the tool can provide at that time when the air or oil pressure supply changes at the job site at any time. Whether the riveting capacity is sufficient to cope with the rivet or cap to be riveted

In use, when the working pressure is too low, the strength of the rivet will be insufficient, and the rivet or cap will be pulled continuously or incompletely, so it must be reworked (use a drilling tool to drill out the rivet or the stuck cap. , and then re-riveted), seriously affecting production capacity

And when the air intake or oil intake pressure is too high, the pressure inside the pneumatic cylinder or hydraulic cylinder will exceed the pressure that the leakage prevention element can withstand, resulting in leakage, and the light one cannot operate normally

In severe cases, the cylinder block of the pneumatic cylinder or hydraulic cylinder may be broken, which may endanger the safety of the operator and other industrial safety accidents.

[0004] Secondly, the design of conventional nail / cap puller guns lacks the design of overpressure pressure display, recording and warning. Therefore, when the air or oil pressure used by the user is too high, the tool will be damaged (the internal leak-proof element is damaged, or even When the pneumatic cylinder or hydraulic cylinder is broken), the cause of product failure and the liability for damages cannot be clarified, resulting in disputes

[0005] Furthermore, the commonly used rivet / cap puller may have a counting function for the riveting operation, but its counting function can be reset to zero, which can only be used as a statistical reference for the batch workload, and cannot provide the total number of times used cumulatively. As the basis for providing tool warranty and reminding users how many times they need to be maintained

[0006] In addition, the commonly used rivet / cap puller does not have a warning function for insufficient riveting stroke, and often waits until the stroke is insufficient, resulting in problems such as poor riveting operation and rework, which seriously affects operation and production capacity.
