Description
Technical field
The utility model relates to a kind of checkout equipment, and especially a kind of three fulcrum Weight measuring type grinding wheel static balancings detect machine.
Background technology
In modern processing and manufacturing process, more come highlyer for the requirement of parts size precision and surfaceness, and most of high-precision part need adopt grinding machine to process, this just requires will reach a standard as the emery wheel quality of grinding tool.Grinder wheel dish balance mass level, directly has influence on workpiece grinding quality.The amount of unbalance of abrasive disc is excessive, is that workpiece (as camshaft, bent axle) grinding skin produces the main cause of straight waveform defect.For making grinding machine processing can ensure dimensional accuracy, percent ripple and surfaceness, lathe is in having high geometric accuracy, rigidity and stability, and its vibration state also has strict requirement.In grinding machine vibration, main is also that the most unsettled vibration source is exactly the unbalance vibration of grinding wheel spindle system; Due to unevenness and other processing factors of emery wheel material, the barycenter of whole emery wheel system always departs from the alignment of shafts, thus grinding wheel spindle when running system cause grinding machine vibration, when grinding, will on surface of the work, leave chatter mark, cause mismachining tolerance.Meanwhile, the emery wheel geometric configuration of repairing out under non-equilibrium state is undesirable, is difficult to grinding and goes out high-quality workpiece.Here it is, and why new emery wheel must detect statically balanced reason.
The conventional sense method of grinding wheel static balancing is that emery wheel is enclosed within on a balance test axle at present, then the two ends of axle are placed on two cutter rails of balancing stand, rotate gently emery wheel, in the time that emery wheel is static, labeling position, be fixed on the upside of emery wheel with sheet lead, then test, change sheet lead or increase the weight of, till test reaches balance repeatedly, the heaviest sheet lead is taken off, on balance, weigh up the quality of sheet lead, by judging that the quality of sheet lead judges the static equilibrium degree of emery wheel.This method wastes time and energy, and can not meet user's requirement.
Utility model content
The purpose of this utility model is to provide a kind of measuring accuracy high, and Measuring Time is short, and workman is simple to operate, and Weight measuring type grinding wheel static balancing easy to maintenance detects machine.
Problem described in the utility model is realized by following technical proposals:
A kind of Weight measuring type grinding wheel static balancing detects machine, special feature is: it comprises brace table, on brace table, fix scroll chuck, on each movable jaw of scroll chuck, be respectively equipped with LOAD CELLS, adjustable supports is fixed at each LOAD CELLS top, and three adjustable supports are positioned on the same circumference taking scroll chuck center as the center of circle.
Above-mentioned Weight measuring type grinding wheel static balancing detects machine, and described static equilibrium detects machine and is also provided with stepper motor, and the output shaft of stepper motor connects spanner through shaft coupling, and one end of spanner is positioned at a claw adjusting hole of scroll chuck.
Above-mentioned Weight measuring type grinding wheel static balancing detects machine, and described adjustable supports, for adjusting screw rod, is adjusted screw rod and is threaded with LOAD CELLS, adjusts screw rod and is provided with adjustment cap.
Above-mentioned Weight measuring type grinding wheel static balancing detects machine, fixation of sensor mount pad on each movable jaw of described scroll chuck, and each sensor is fixed on sensor installation seat.
Above-mentioned Weight measuring type grinding wheel static balancing detects machine, and described static equilibrium detects machine and is also provided with single-chip microcomputer, single-chip microcomputer and LOAD CELLS connection.
Above-mentioned Weight measuring type grinding wheel static balancing detects machine, and the supporting leg bottom of described brace table is provided with outrigger plate, and outrigger plate is provided with foot bolt.
The utility model improves for improving grinding wheel static balancing accuracy of detection and detection efficiency problem, has designed a kind of three fulcrum Weight measuring type grinding wheel static balancings and has detected machine.Described static equilibrium detects machine detected emery wheel is placed into the stressed measurement of carrying out three fulcrums on a weighing device.Three are detected fulcrums 120 degree of being separated by respectively, and on the same circumference taking emery wheel center as the center of circle, each fulcrum is all furnished with a LOAD CELLS, measures respectively the weight of three positions of emery wheel.If this grinding wheel static balancing reaches requirement, the suffered pressure of the LOAD CELLS of three positions differs very little so; If the pressure that three positions are subject to differs larger, the static equilibrium of this emery wheel does not reach requirement.Concrete static equilibrium parameter can be calculated out by the difference of three sensor detection signals.The utility model adopts the dynamo-electric mode combining to detect grinding wheel static balancing, and compared with the detection method of traditional grinding wheel static balancing, measuring accuracy is high, and Measuring Time is short, and manual operation is simple.The utility model also has the features such as device structure is simple, cost of manufacture is low, be easy to realize, the scope of application is wide.
