Abstract
The utility model relates to the technical field of a measuring device, particularly to a thin wall type annular workpiece inner circle measuring device. The thin wall type annular workpiece inner circle measuring device comprises a base plate and a thin wall annular workpiece, wherein the base plate, arranged in the thin wall type annular workpiece, is provided with a handgrip, a main column and an auxiliary column, with the handgrip located at the central position of the base plate, the main column located at one side of the base plate, and the auxiliary column located at the other side of the base plate. The main column is provided with a dial gauge while the auxiliary column is provided with a contact steel ball, with the dial gauge being fixed via a locking screw. The thin wall type annular workpiece inner circle measuring device can conveniently and accurately measure the outer circle diameter of a thin wall type annular workpiece and reduce the elastic deformation caused by the clamp force of the measuring tool. The thin wall type annular workpiece inner circle measuring device can measure the outer circle diameter of the annular workpiece having different specifications and the outer circle diameter of other devices made in a similar way. The thin wall type annular workpiece inner circle measuring device, with a simple structure, is easy to operate.
Description
Technical field
The utility model relates to a kind of measurement mechanism, relates in particular to circle measurement mechanism in a kind of thin-walled class annular workpieces.
Background technology
The cylindrical of thin-walled class annular workpieces is when detecting with common micrometer inside caliper; Because the expansion force (in a straight line) of measurer makes workpiece produce elastic deformation easily; The result causes having error between measured value and the actual value, is difficult to accurately measure its actual value for the higher workpiece of accuracy requirement.
Summary of the invention
The technical matters that the utility model will solve is: at the outer bowlder that detects thin-walled class annular workpieces; Because the expansion force (in a straight line) of measurer makes workpiece produce elastic deformation easily; The result causes having error between measured value and the actual value; Be difficult to accurately measure its actual value for the higher workpiece of accuracy requirement, circle measurement mechanism in a kind of thin-walled class annular workpieces is provided.
In order to overcome the defective that exists in the background technology; The utility model solves the technical scheme that its technical matters adopted: the circle measurement mechanism comprises base plate and circular thin-wall workpiece in this thin-walled class annular workpieces, and base plate places in the thin wall type annular workpieces, and said base plate is provided with handgrip, head tree and secondary column; Said handgrip is positioned at the center of base plate; Said head tree is positioned at a side of base plate, and said secondary column is positioned at the opposite side of base plate, and said head tree is provided with clock gauge; Said secondary column is provided with the contact steel ball, and said clock gauge is fixed by lock-screw.
According to another embodiment of the utility model, what further comprise said head tree, secondary column and base plate is connected to form " Y " shape.
The beneficial effect of the utility model is: the circle measurement mechanism can make things convenient for, measure accurately the diameter of thin-walled class annular workpieces cylindrical in this thin-walled class annular workpieces, reduces because the elastic deformation that the clamping force of measurer produces.The circle measurement mechanism is made similar device and can be realized measuring its outside diameter for the various annular workpieces of different size in this thin-walled class annular workpieces.The circle measurement mechanism is simple in structure, easy to operate in this thin-walled class annular workpieces.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Wherein: 1, head tree, 2, clock gauge, 3, handgrip, 4, the contact steel ball, 5, secondary column, 6, base plate, 7, the circular thin-wall workpiece.
Embodiment
Fig. 1 is the structural representation of the utility model; Comprise base plate 6 and circular thin-wall workpiece 7 among the figure, base plate 6 places in the thin wall type annular workpieces 7, it is characterized in that: said base plate 6 is provided with handgrip 3, head tree 1 and secondary column 5; Said handgrip 3 is positioned at the center of base plate 6; Said head tree 1 is positioned at a side of base plate 6, and said secondary column 5 is positioned at the opposite side of base plate 6, and said head tree 1 is provided with clock gauge 2; Said secondary column 5 is provided with contact steel ball 4, and said clock gauge 2 is fixing by lock-screw 8.
Said head tree 1, secondary column 5 and base plate 6 be connected to form " Y " shape.
Circle measurement mechanism in this thin-walled class annular workpieces; The head tree 1 that base plate 6 connects is provided with clock gauge 2 and contacts 3 contacts of steel ball 4 formation with secondary column 5; Because clamping force not point-blank, is distributed on 3 of circular thin-wall workpiece 7, clamping force significantly reduces like this; Thereby reduced the elastic deformation of workpiece, can measure accurately.
Base plate 6 is placed in the circular thin-wall workpiece 7, clamped by the clock gauge 2 on contact steel ball on the secondary column 54 and the head tree 1, clock gauge 2 is used for measuring diameter of a circle, utilizes the variation of clock gauge and the funtcional relationship of diameter to draw the diameter of measuring the back workpiece.
The circle measurement mechanism can make things convenient for, measure accurately the diameter of thin-walled class annular workpieces cylindrical in this thin-walled class annular workpieces, reduces because the elastic deformation that the clamping force of measurer produces.The circle measurement mechanism is made similar device and can be realized measuring its outside diameter for the various annular workpieces of different size in this thin-walled class annular workpieces.The circle measurement mechanism is simple in structure, easy to operate in this thin-walled class annular workpieces.
