Description
Technical field
The utility model relates to a kind of flatness and depth of parallelism MEASUREMENT TEACHING instrument, it is used in Metalworking Practice Teaching to tested
The aided education that the flatness and the depth of parallelism for measuring workpiece measure.
Background technique
In professional colleges, Milling Process is an important course in machining manufacture Practice Curriculum.Milling Machining work
The measurement of paralleism of the flatness and opposing sides of part is the preliminary basis for understanding origin reference location and the study of following process content.?
Three kinds of method measurement planes are generallyd use during flatness and depth of parallelism MEASUREMENT TEACHING.The first is to place workpiece and scriber
On same plate.The mobile scriber bottom plate of operator keeps the needle point of scriber mobile in workpiece surface, observes on needle point and workpiece
The flatness and the depth of parallelism of the alternate position spike estimation workpiece surface on surface.Second method is to fix dial gauge using Magnetic gauge stand,
Workpiece different location is measured using dial gauge, the indicating value difference of dial gauge is flatness or parallelism error.The third is to utilize
The flatness and verticality of level measurement plane.In above-mentioned three kinds of methods, the measurement accuracy of scriber is poor and is not easy to observe.Hundred
Divide table measurement not easily shifted, travelling workpiece easily damages dial gauge.And both of which can not embody entire workpiece surface
Flatness fluctuating situation.It needs formula to calculate using level measurement, and can not be embodied by the MEASUREMENT TEACHING effect of benchmark.
Three kinds of instruments used for education cannot all be applied in teaching practice well.
Summary of the invention
The utility model problem to be solved is: providing a kind of flatness depth of parallelism that structure is simple and convenient to operate survey
Measure instruments used for education.
A kind of flatness and depth of parallelism MEASUREMENT TEACHING instrument, including pedestal and support frame, it is characterised in that: the pedestal
On be provided with support frame, be provided with pin between the pedestal and the support frame, the pedestal and the support
At 90 degree between frame, it is provided with sliding slot in the support frame, measuring rod is provided in the sliding slot, the measuring rod can
It is moved up and down in the sliding slot, locking nut, the measurement is provided between the measuring rod and support frame as described above
Shifting chute is set in bar, dial indicator holder is provided in the shifting chute, the dial indicator holder includes fixture nut and fixation
Bolt is provided with fastener between the dial indicator holder and the shifting chute.
The side of support frame as described above is provided with straight edge ruler, is arranged rotary shaft on the pedestal, in the rotary shaft
It is provided with tripod, multiple location holes are evenly arranged on the tripod, positioning column is set in the location hole.
The effect of the utility model is: can in teaching process it is good embody it is general as the measurement of positioning measurement using benchmark
It reads, and can be on the whole with embodiment flatness and depth of parallelism situation in specific data, structure is simple, and connection is reliably not easy
Damage.The good aided education of energy, embodies the content of courses.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model；
Fig. 2 is the structural perspective of the utility model.
Specific embodiment
Utility model is described further with reference to the accompanying drawing.
As shown in the figure: 1. pedestals, 2. pins, 3. locking nuts, 4, measuring rod, 5. support frames, 6. fixture nuts, 7. is fixed

A kind of flatness and depth of parallelism MEASUREMENT TEACHING instrument, including pedestal (1) and support frame (5), it is characterised in that: pedestal
(1) be provided with support frame (5), be provided between pedestal (1) and support frame (5) pin (2) on, pedestal (1) and support frame (5) it
Between at 90 degree, be provided with sliding slot in support frame (5), be provided in sliding slot measuring rod (4), measuring rod (4) can be in sliding slot up and down
It is mobile, it is provided between measuring rod (4) and support frame (5) locking nut (3), setting shifting chute in measuring rod (4), in shifting chute
Be provided with dial indicator holder (8), dial indicator holder (8) includes fixture nut (6) and fixing bolt (7), dial indicator holder and shifting chute it
Between be provided with binding groove.
The side of support frame (5) is provided with straight edge ruler, and swivelling chute is arranged on pedestal (1), is provided with and has on swivelling chute
The tripod (10) of rotary shaft is evenly arranged with multiple location holes on tripod (10), positioning column (9) is arranged in location hole.
Instrument is in use, first should be according to the position of three positioning columns (9) of big minor adjustment of measured workpiece, it is ensured that three
A positioning column (9) being capable of good positioning plane.Specific practice is to be positioned three according to the size of the datum level of measured workpiece
Column (9) is placed in the reasonable location hole of tripod (10).
When teaching, workpiece to be measured is placed in above three plane positioning columns (9), unclamps and adjusts bolt (3), make to measure
Bar (4) can be moved up and down freely along support frame (5) sliding groove, manually be contacted measuring rod (5) with workpiece surface, gently
It gently screws and adjusts bolt (3), make measuring rod (4) and support frame (5) accurate positioning, slightly adjust measuring rod (5), screw adjusting spiral shell
Bolt (3) observes and measures the edge of a knife of bar (4) and the contact condition of workpiece surface to confirm the entirety on surface using light transmission method
Flatness and the depth of parallelism.Or dial gauge is installed on dial gauge gauge stand (8), it will using fixing bolt (7) and fixture nut (6)
Dial gauge is fixed vertically.Adjusting dial gauge and workpiece surface using adjusting bolt (3) when measurement has suitable meter-pressing amount, mobile
Dial indicator holder (8), observation dial gauge indicating value determine the specific difference of flatness and the depth of parallelism.According to specific measurement needs, pass through
Change the measurement position that plane positioning column (9) change workpiece in the position of tripod (10) location hole or rotation tripod, weight
Multiple measuring process, with the flatness of the entire plane of determination and by the depth of parallelism of side and datum level.
