The measuring instrument comprises a fixed supporting point (1), a gauge frame (4), a measuring platform (5), a movable supporting point (6) and a driving guide roller (7), wherein the measuring platform is arranged in a way of forming an angle alpha with a horizontal plane; the bottom end of the measuring platform is provided with the fixed supporting point; the left end of the measuring platform is provided with the movable supporting point; the upper end of the measuring platform is provided with the gauge frame; the right end of the measuring platform is provided with the driving guide roller; the included angle between the horizontal axis of the driving guide roller and a vertical movement supporting point is 45 degrees; the circular workpiece (2) is pushed inwards from the right face of the measuring platform, and the fixed supporting point is relatively fixed, so that contact of the movable supporting point with the circular workpiece needs adjusting and the movable supporting point is tightly pressed against the driving guide roller; and when the driving guide roller rotates at a uniform speed, the circular workpiece is rotated at a uniform speed, the measuring head (3) of the gauge frame can be used for measuring the outer diameter measuring ellipticity of the circular workpiece, and the difference between a maximum diameter and a minimum diameter reflected by the gauge frame is the ellipticity of the circular workpiece. The measuring instrument has a simple and practical structure, and a reliable ellipticity measuring result can be achieved.
Description
Technical field
The utility model belongs to the measuring instrument technical field, especially a kind of measuring instrument that is used for the detection of round piece ovality.
Background technology
Measuring instrument such as clock gauge, twisted-coil comparator and inductance instrument can measure the poor of the maximum gauge of round piece and minimum diameter, and the difference of being somebody's turn to do is called the variation in diameter amount in the single sagittal plane, is commonly called as ovality.
Using the process of measuring instrument is to rotate round piece by hand, requires turning moment and invariablenes turning speed.And in the actual measurement process, rotate requirement that round piece will reach turning moment and invariablenes turning speed by hand and be difficulty very.
Summary of the invention
In order to address the above problem, the utility model has designed a kind of measuring instrument that the round piece ovality detects that is used for, and this measuring instrument can make round piece be subjected to constant turning moment and rotating speed is at the uniform velocity constant, thereby solves the detection error that human factor caused.
For achieving the above object, the utility model adopts following technical scheme:
The described measuring instrument that is used for the detection of round piece ovality comprises decides fulcrum, dial framework, measuring table, mobile fulcrum and active deflector roll, measuring table becomes the α angle to be provided with surface level, be provided with in the bottom of measuring table and decide fulcrum, left end at measuring table is provided with mobile fulcrum, the upper end of measuring table disposes dial framework, the right-hand member of measuring table is provided with initiatively deflector roll, and initiatively the horizontal axis of deflector roll and the angle of vertical moving fulcrum are 45 °.
Owing to adopt technical scheme as mentioned above, the utlity model has following beneficial effect:
1, initiatively deflector roll is that diameter is the roll shaft of D, and round piece contacts with active deflector roll line, and initiatively deflector roll is even to the friction force of round piece, thereby reduces the vibration that round piece produces because of unbalance stress as far as possible.
2, initiatively the material of deflector roll has certain elasticity and friction factor height, initiatively deflector roll to the friction drive of round piece be equal to or greater than mobile fulcrum, decide fulcrum, measuring point and measuring table be to the frictional resistance of round piece.
3, because the active deflector roll can be the n uniform rotation by DC MOTOR CONTROL and with the rotating speed, thereby the realization round piece is done uniform rotation, and rotating speed is n
w=D * n/d, wherein d is the round piece diameter.
4, measuring table becomes the α angle with surface level, so round piece can be close to the measuring table face by the effect of himself gravity, finally realizes the measurement of gauge head to round piece external diameter ovality.
The utility model is simple and practical, the ellipticity measurement reliable results.
Description of drawings
Fig. 1 is an instrumentation plan of the present utility model.
Fig. 2 is that the A of Fig. 1 is to synoptic diagram.
Among the above-mentioned figure: 1-decide fulcrum; 2-round piece; 3-gauge head; 4-dial framework; 5-measuring table; 6-mobile fulcrum; 7-initiatively deflector rolls.
Embodiment
In conjunction with Fig. 1-2, the utility model is used for measuring instrument that the round piece ovality detects and comprises and decide fulcrum 1, dial framework 4, measuring table 5, mobile fulcrum 6 and deflector roll 7 initiatively.
Measuring table 5 becomes the α angle to be provided with surface level as can be seen from Figure 1, and the α angle is preferably disposed between the 20-35 degree, and round piece can be close to measuring table 5 faces by the effect of himself gravity, to realize the measurement of 3 pairs of round piece external diameters of gauge head ovality.
Be provided with in the bottom of measuring table 5 and decide fulcrum 1, described to decide fulcrum 1 be relatively-stationary.
Left end at measuring table 5 is provided with mobile fulcrum 6, and mobile fulcrum 6 can arbitrarily be adjusted according to the diameter of round piece.
The upper end of measuring table 5 disposes dial framework 4, and the gauge head 3 of dial framework 4 is arbitrarily adjusted according to the diameter of round piece equally.
The right-hand member of measuring table 5 is provided with initiatively deflector roll 7, and initiatively the horizontal axis of deflector roll 7 and the angle of vertical moving fulcrum 6 are 45 °.Initiatively deflector roll can be the n uniform rotation by DC MOTOR CONTROL and with the rotating speed, thereby the realization round piece is done uniform rotation, and rotating speed is n
w=D * n/d, wherein d is the round piece diameter.
Deciding 6 pairs of round pieces of fulcrum 1 and mobile fulcrum contacts to well with line.
When the round piece ovality detects, the right side of round piece 2 from measuring table 5 is pushed on the measuring table 5, because it is relatively-stationary deciding fulcrum 1, at this moment will adjust mobile fulcrum 6 contacts with round piece 2, and round piece 2 is abutted against on the active deflector roll 7, initiatively deflector roll 7 can be realized control by pneumatic shuttle with the contact pressure of round piece 2.When active deflector roll 7 at the uniform velocity rotated, round piece 2 was also at the uniform velocity rotated, and at this moment the gauge head 3 of dial framework 4 can be to the outside diameter measuring ovality of round piece 2, and the maximum gauge of dial framework 4 reflections and the difference of minimum diameter are the ovality of this round piece 2.
