The invention discloses a positioning device for easily assembling a pressure meter. The positioning device comprises a lower module, an upper module and an assembling piece. The assembling piece comprises an assembling screw and a motor. One end of the screw is connected with a driving rotation shaft of the motor through a coupling. The other end of the assembling screw is equipped with a fixing groove capable of fixing a screw. The upper module communicates with a hydraulic cylinder through a telescoping rod. The upper module moves from left to right driven by the hydraulic cylinder. The upper module is fixed on the inner side of a left limiting block. The lower module is fixed on the inner side of a right limiting block. The positioning device is simple in structure and convenient to operate. A dial of the pressure meter is manually arranged in the module groove and the upper and lower templates are well placed so the pressure meter can be assembled; and by use of the motor for automatic assembling, manual operation is reduced and working efficiency is increased.
Description
technical field [0001] The invention relates to the technical field of instrument equipment, in particular to a positioning device for conveniently assembling pressure gauges. Background technique [0002] General conventional pressure gauges include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc. Various pressure gauges currently in use are equipped with voltage stabilizers, which are specially used to stabilize the voltage of the instrument power supply and suppress fluctuations to ensure the accuracy of the pressure gauge. In addition, the basis for most of the instruments displayed comes from sensors, and the sensing device changes its resistance value according to the state change of the monitored object, which is expressed through the instrument. [0003] The most conspicuous thing in the dashboard is the speedometer, which indicates the speed of the car in km / h. The speedometer actually consists of two gauges, o...
