Abstract

PURPOSE:To secure a space capable of using a large diametral grinding wheel as well as to improve a layout property of the wheel, by measuring each position of both specified inner and outer circumferential surface measuring points of a work, while calculating a value of bore size of the work from this measured value. CONSTITUTION:A work 1 is supported by a shoe having each contact point fixed with an outer circumferential surface of the measured work 1 on x and y coordinates. Each of x coordinates Bx and Ax of measuring points B and A is secured from both first and second measuring parts 2 and 3. And, both these coordinates are inputted into an operational part 4, and hereat a bore (r) is calculated and simultaneously from finishing size r0 for the bore (r) and the work 1, an infeed rate M for securing this finishing size r0 is calculated and outputted. This infeed rate M is inputted into a control unit whereby the work having the accurate bore size r0 is secured. Thus, each measuring point on both inner and outer surfaces of the work is measured, and it will get off with only setting up one contact maker 2a inside the work 1 so that a large grinding wheel is usable as much as a portion for that, thus a layout property in the wheel and machining accuracy are improved.

工中に測定しながら上記切込量を増してゆく訳である。Conventionally, a plurality of support members each having abutting portions fixed in contact with the outer peripheral surface of an annular workpiece are disposed at set intervals in the circumferential direction of the workpiece, and the workpiece is supported by the support members and the workpiece is supported by the support members. When grinding the inner surface of a workpiece, the depth of cut of the grindstone is increased using an internal grinder until the inner diameter of the workpiece reaches a predetermined reference dimension, and in this case, The depth of cut is increased while measuring the inner diameter of the workpiece during machining.

った。Conventionally, as a device for measuring the inner diameter dimension in such internal grinding, the first. There is a device in which the second measuring element is brought into contact with opposing parts of the inner peripheral surface of the workpiece, and the inner diameter dimension of the workpiece is determined from the output of both measuring elements.
In this conventional device, since the two probes are located on the inner periphery of the workpiece, only a grindstone with a small diameter can be used, resulting in a problem in that the layout of the grindstone and processing accuracy tend to deteriorate.

Measure and memorize the outer diameter Do of

。In the conventional device described in this publication, there is only one measuring element on the inner circumference of the workpiece, and therefore, a correspondingly larger grindstone can be used. However, since the conventional device described in this publication measures and stores the outside diameter DO of each workpiece to be measured in advance, it is natural that an outside diameter measuring device and a storage device are required in addition to the above-mentioned in-process gauge. However, there is a problem that the structure becomes complicated and the device becomes large, and there is also a problem that the number of steps for measuring the outer diameter is increased compared to the conventional example in which two points on the inner peripheral surface of the workpiece are measured.

ことはできなかった。In addition, when the workpiece is supported by multiple support members as described above, the center position of the grinding hole of the workpiece shifts due to variations in the outer diameter of the workpiece, and it is not possible to simply move the probe on a fixed straight line. It was not possible to accurately measure the inner diameter dimension.

Accurate internal diameter measurements can be obtained by simply measuring one measurement point on the inner and outer surfaces of the workpiece, improving machining accuracy without complicating the structure or increasing the number of processes. The object of the present invention is to provide a device for measuring the inner diameter dimension of a workpiece in an internal grinding machine, which can also improve layout properties.

In an internal diameter measuring device for a workpiece in an internal grinding machine that grinds the inner surface of the workpiece, the position of the inner peripheral surface measurement point on a predetermined measurement line of the workpiece and the position of the outer peripheral surface measurement point on the said measurement line of the workpiece are measured. , the inner diameter dimension of the workpiece is calculated from the measured value of this repositioning, thereby eliminating the need to measure the outer diameter of the workpiece in advance, and arranging one measuring element on the inner circumference of the workpiece. This makes it possible to obtain the correct inner diameter of the workpiece with just one step.

Further, in the above embodiment, the inner diameter dimension is calculated, the depth of cut M is determined, and the grinding is performed using this depth of cut M. However, in the present invention, it is not necessarily necessary to calculate the depth of cut, and for example, It is also possible to continuously calculate the inner diameter dimension and stop the cutting feed when the inner diameter reaches a predetermined value.

ところで、上記実施例ではある測定線上の内。By the way, in the above-mentioned example, within a certain measurement line.

To explain how to calculate the total amount ■, first, the X coordinates Ax and Cx of measurement points A and C are Ax = (RO + ΔR) (1 + cos θ) Cx - RQ
