Abstract
A roundness error detector is characterized in that a stepping motor is installed on a pedestal through a motor support; an output shaft of the stepping motor is connected with a tail portion of a main shaft through a shaft coupling; the main shaft is installed on the pedestal through a bearing pedestal assembly; a front end of the main shaft is provided with a chuck; a right end of the pedestal is provided with a tip assembly. A left end of a detected workpiece is clamped through the chuck and a right end is pressed tightly through the tip assembly. A pointer gauge is fixed on the pedestal through a magnetic force meter seat. A detection point of the pointer gauge abuts against an upper bus of the detected workpiece. By using the detector of the utility model, a student can visually know a measurement process and a method of a roundness error. Cost is low and manufacturing is simple. The detector possesses practicality and scientificity.
Description
Technical field
The utility model relates to a kind of measuring instrument, is specially adapted to a kind of deviation from circular from detector.
Background technology
Machine tool chief axis revolution imbalance in mechanical component working angles, the friction of cutter in cutting and between main shaft, and the residual surface stress in manufacture process, all can cause the variation of radius, brings deviation from circular from.The existence of deviation from circular from directly affects quality of fit, running accuracy, friction, vibrations, noise of parts etc., thereby has reduced their serviceable life.So modern age, high-precision rotary body ring-shaped work pieces, proposed more and more higher requirement to deviation from circular from.Deviation from circular from observation and control technology arouses extensive attention.
Increasing novel circularity error detector arises at the historic moment in recent years, automaticity is very high mostly, simple to operate, but complex structure, cost is higher, being applicable to factory measures, improve the quality of engineering goods, and be not suitable for Teaching in University, student is difficult to deeply understand the measuring principle of deviation from circular from, for the ease of observing and research, the utility model provides a kind of deviation from circular from detector.
Summary of the invention
Goal of the invention: the utility model provides a kind of deviation from circular from detector, its objective is by instrumentation, completes measuring process, deepens the understanding to knowledge, allow student deeply understand measuring process and the method for deviation from circular from, and cost is low.
Technical scheme: the present invention implements according to following technical scheme: a kind of deviation from circular from detector, is characterized in that: stepper motor (2) is arranged on base (1) by electric machine support (3); The output shaft of stepper motor (2) is connected with the afterbody of main shaft (6) by shaft coupling (4); Main shaft (6) is arranged on base (1) by bearing block assembly (5); The front end of main shaft (6) is provided with chuck (7); The right-hand member of base (1) is provided with top assembly (11).
A deviation from circular from detector, is characterized in that: measured workpiece (8) left end clamps by chuck (7), and right-hand member holds out against by top assembly (11).
A deviation from circular from detector, is characterized in that: it is upper that pointer gauge (9) is fixed on base (1) by magnetic stand (10), and the chaining pin of pointer gauge (9) withstands on the Up Highway UHW place of measured workpiece (8).
Advantage and effect: by enforcement of the present utility model, enriched classroom, make student can get information about measuring process and the method for deviation from circular from, and cost has been low, manufactured simple and easyly, there is practicality, science.
Accompanying drawing explanation
Fig. 1 is primary structure schematic diagram of the present utility model.
In Fig. 1, mark 1-base; 2-stepper motor; 3-electric machine support; 4-shaft coupling; 5-bearing block assembly; 6-ladder main shaft; 7-chuck; 8-measured workpiece; 9-pointer gauge; 10-magnetic stand; 11-top assembly.
Embodiment
A deviation from circular from detector, is characterized in that: stepper motor (2) is arranged on base (1) by electric machine support (3); The output shaft of stepper motor (2) is connected with the afterbody of main shaft (6) by shaft coupling (4); Main shaft (6) is arranged on base (1) by bearing block assembly (5); The front end of main shaft (6) is provided with chuck (7); The right-hand member of base (1) is provided with top assembly (11).
A deviation from circular from detector, is characterized in that: measured workpiece (8) left end clamps by chuck (7), and right-hand member holds out against by top assembly (11).
A deviation from circular from detector, is characterized in that: it is upper that pointer gauge (9) is fixed on base (1) by magnetic stand (10), and the chaining pin of pointer gauge (9) withstands on the Up Highway UHW place of measured workpiece (8).
During measurement, first pointer gauge (9) is returned to zero; By stepper motor (2), main shaft (6) is rotated to an angle again, after stable, reading the record of reading pointer table (9); And then to this angle of same direction rotation, after stable, reading the record of reading pointer table (9); Until main shaft (6) rotates a circle; Finally according to reading Calculation of Roundness Error.
The angle of the each rotation of main shaft (6) is larger, and the reading rotating a circle is fewer, calculates simplyr, but measuring accuracy is lower.
