Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing: the instrument of this measurement endoporus cylindricity in the present embodiment, comprise bracing frame 1, bracing frame 1 is provided with V-arrangement locating slot 2, inside and outside V-arrangement locating slot 2, both sides are separately installed with guide rail 3, guide rail 3 are provided with sliding bearing 4, are fixed with fixed mount 5 between sliding bearing 4, the top of fixed mount 5 is provided with servomotor 6, servomotor 6 drives and has been connected with elevating lever 6-1, and the rotation axis 7 of the lower horizontal setting of elevating lever 6-1, the outer end of rotation axis is provided with dial gauge 8.V-arrangement locating slot 2 is for placing the workpiece needing to measure endoporus cylindricity, and certain fixation is played to workpiece, servomotor 6 drives rotation axis 7 to drive dial gauge 8 rotation to carry out error measure, and servomotor 6 is slided on guides 3 by sliding bearing 4 and adjusts position simultaneously.
Guide rail 3 is slidably fitted with sliding shoe 9, sliding shoe 9 is provided with the slip locating slot 10 corresponding with V-arrangement locating slot 2.Slip locating slot 10 is arranged needing the workpiece measured to serve better fixation with the corresponding of V-arrangement locating slot 2, adds stability during workpiece calibration.Guide rail 3 comprises upper rail 3-1 and lower guideway 3-2, and upper rail 3-1 and lower guideway 3-2 is each passed through sliding shoe 9.The setting of upper rail 3-1 and lower guideway 3-2 adds the stability of sliding shoe 9, ensure that the precision of measurement.Sliding shoe 9 is slidably matched with upper rail 3-1 and lower guideway 3-2 respectively by linear bearing.The setting of linear bearing make slip 9 pieces and being slidably matched between upper rail 3-1, lower guideway 3-2 more smooth.Bracing frame 1 comprises base 11, is fixed on the fixed head 12 at base about 11 two ends, and the fixed head 12 on base 11 left end is provided with described V-arrangement locating slot 2.
With the revolution class mould product of endoporus owing to being assembled by two parts, so be difficult to the cylindricity of measurement products endoporus.The utility model, can the circularity of measurement products endoporus for having the mould product of requirement to internal via shape error with endoporus and design, cylindricity, the shape errors such as linearity.
Principle: the shape error measuring the endoporus of different size, as long as the position finding the center of circle, then rotates dial gauge 8, draws deviation from circular from.Because workpiece is placed on V-arrangement locating slot 2, even if so the diameter change of part, the position of the different-diameter center of circle in x-axis is always constant, and the change of home position only appears in z-axis.
Using method: first look for a slice standard specimen, the i.e. agonic test specimen of endoporus circularity in theory, suppose this test specimen external diameter 50mm, put on the table.By dial gauge 8 i.e. whole falsework toward moving down, until the amount head of dial gauge 8 has certain precompression with absorption surface, now, rotation dial gauge 8, dial gauge 8 pointer is not beated in theory, does not namely have deviation from circular from.Then the product that will measure is measured.Suppose product external diameter 40mm, can calculate according to mathematical knowledge and move down 7.0711mm relative to the workpiece of 50mm.
Although the utility model has illustrated by reference to preferred embodiment and has described, those skilled in the art should understand, and in the scope of claims, can do the various change in form and details.
