Automatic accurate adjustment system for instrument movement clearance

Abstract

The invention discloses an automatic accurate adjustment system for an instrument movement clearance. The automatic accurate adjustment system comprises a work table, a handpiece module, an engine base module, a shifting module, a laser displacement sensor module and a controller. The handpiece module comprises a cutter head and a cutter head drive mechanism; the shifting module comprises a shifting plate and a shifting plate drive mechanism; the laser displacement sensor module comprises a probe, a laser displacement sensor and a probe drive mechanism; the signal output end of the laser displacement sensor is connected with the controller; and the control ends of drive elements in the cutter head drive mechanism, the shifting plate drive mechanism and the probe drive mechanism are connected with the controller. A clearance between a lower bearing and a shaft tip in a measurement mechanism of an electrical measuring instrument to be adjusted is detected by using the shifting plate, the probe and the laser displacement sensor, an adjustment quantity is output by using the controller according to a detection signal, and axial displacement is generated by driving the lower bearing through the cutter head, so that the accurate adjustment of the clearance between the lower bearing and the shaft tip is realized. The automatic accurate adjustment system is short in machining period, low in cost and high in efficiency; and moreover, the batch uniformity and the stability of the accuracy can be improved.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to the production and assembly technology of electrical measuring instruments, in particular to a precision automatic adjustment system for the movement gap of an instrument. Background technique: [0002] In the prior art, the adjustment of the gap between the lower bearing and the shaft tip of the measuring mechanism (standard movement) in the electrical measuring instrument is carried out by the workers using a screwdriver to tap and compare the sealing sample, and its precision is completely controlled by the proficiency of the workers. It often leads to inconsistent batch precision of the instrument measuring mechanism (standard movement), easy to cause instrument sluggish jamming during the assembly process, high repair rate and poor stability, requiring a lot of manpower and material resources to correct, high production cost and low efficiency low and unstable product quality.
