Abstract
The utility model discloses a testing fixture used for detecting workpiece planeness. The testing fixture is used for detecting the machining planeness of a to-be-detected workpiece. The testing fixture includes an L-shaped base and at least two detection instruments. The L-shaped base is provided with a first reference plane and a second reference plane. The first reference plane is horizontally arranged. A loading plane and a to-be-detected plane of the to-be-detected workpiece can cling closely to the first reference plane and the second reference plane respectively. The at least two detection instruments are installed on the second reference plane in parallel and located on the same horizontal plane. Detection heads of the detection instruments extend out from the second reference plane and are located on the same line. The detection heads of the detection instruments are used for abutting against the to-be-detected plane of the to-be-detected workpiece. Through observation of the change of numbers of the detection instruments, the testing fixture judges the machining planeness of the to-be-detected plane more accurately. Compared with detection of the planeness of a to-be-detected workpiece through adoption of a simple testing fixture, the testing fixture is convenient and rapid in detection, high in detection sensitivity and more accurate in detection result.
Description
Technical field
The utility model relates to planeness of workpiece detection technique field, relates in particular to a kind of cubing for detection of planeness of workpiece.
Background technology
In mechanical processing industry, the piece surface after machine work or die casting, the blank surface of casting, its flatness has technical requirement, must after measuring, judge that whether it is qualified.
Current better simply detection method is: choosing workpiece plane opposite face to be measured is reference field, measures plane to be measured many places height with the precision measurement such as vernier caliper, milscale instrument, and the time that detection workpiece needs is longer.For the detection of workpiece slope that there is no relative datum face, must choose on workpiece multiple reference fields and treat lining face and detect, not only detecting step is comparatively loaded down with trivial details, and also out of true of result.
And existing flatness checking device is detecting when workpiece, performance is single, cannot regulate, and detects the time that workpiece needs longer simultaneously, and very high to the requirement on machining accuracy of workpiece, cannot carry out mass detection.And a lot of adjustable pick-up units often occur that equipment volume is too huge, mobile inconvenient problem.But cannot meet for producing required quick, a large amount of testing requirement.
Utility model content
In order to solve the technical matters existing in background technology, the utility model proposes a kind of cubing for detection of planeness of workpiece, detect the flatness of plane to be measured by the difference of dial gauge, not only easy to detect quick, and detection sensitivity is high, testing result is more accurate.
A kind of cubing for detection of planeness of workpiece the utility model proposes, for the processing plane degree of workpiece for measurement is detected, comprise L-type base and at least two measuring instruments, wherein, L-type base has the first reference field and the second reference field, the first reference field is horizontally disposed, the load plane of workpiece for measurement and plane to be measured can be adjacent to respectively the first reference field and the second reference field, at least two measuring instruments are installed in parallel on the second reference field and are positioned in same level, the detection head of measuring instrument stretches out and is located along the same line from the second reference field, the detection head of measuring instrument is for conflicting with the plane to be measured of workpiece for measurement.Along reference field translation workpiece for measurement, by observing the variation of measuring instrument numerical value, judge the processing plane degree of plane to be measured.
Preferably, described cubing comprises three measuring instruments.
Preferably, described measuring instrument is dial gauge or clock gauge or ten thousandth micrometer.Dial gauge, clock gauge, ten thousandth micrometer are all principles of utilizing rack pinion or lever-gear transmission, the straight-line displacement of sounding rod are become to the measurement instrument of the angular displacement of pointer; The measuring head of instrument contacts with plane to be measured, and the small rectilinear movement of sounding rod that plane out-of-flatness to be measured causes is amplified through gear drive, becomes the rotation of pointer on index dial, thereby judges the processing plane degree of plane to be measured.
Preferably, the angle between described the first reference field and described the second reference field is 90 °.
Preferably, the plane to be measured of described workpiece for measurement is inclined-plane or vertical plane.
The utility model is for detection of the cubing of planeness of workpiece, utilize the sensitivity of measuring instrument to detect the flatness of plane to be measured, in order to improve accuracy and the practicality of detection, adopt plural measuring instrument, by observing the variation of measuring instrument numerical value, more accurately judge the processing plane degree of plane to be measured.Compared with the flatness that detects workpiece with the simple and easy cubing of employing, the utility model is not only easy to detect quick, and detection sensitivity is high, and testing result is more accurate.
Brief description of the drawings
