Problems solved by technology

Furthermore, combining the detections of the two measuring heads for the measurement is also influenced by the mutual arrangement existing between the two measuring heads and possible modifications of said arrangement
Furthermore, probing and handling operations are slow, and the device must be manually reset whenever the nominal diameter size of the workpiece being inspected changes, therefore, this means machine downtime and thus considerable time lost

Embodiment Construction

[0016] Now refer to image 3 A computer numerically controlled ("CNC") grinding machine 1 includes a bed 2 to which is attached a grinding wheel carriage 3 for supporting a spindle 4 defining an axis 5 of rotation of a grinding wheel 6. The grinding wheel carriage 3 can be moved along with respect to the bed 2 in a well-known manner. image 3 Move in the direction of the arrow F shown.

[0017] A table 7 carrying the workpiece to be inspected (for example, the shaft 8 of a compressor with at least one cylindrical eccentric portion, or pin 8') is attached between a mandrel and an end pin seat (not shown). On the bed 2 between them, they define an axis of rotation 9 that coincides with the main geometric axis of the workpiece 8 . Thus, during the rotation of the workpiece 8, the crank pin 8' performs an eccentric movement about the axis 9.

[0018] Furthermore, a device 10 is attached to the bed 2, also shown in Figure 4 and 5 Among them, it is used to check the diame...

Abstract

An apparatus (10) for checking the diameter of an eccentric pin (8') of a small-size shaft (8), for example a shaft for compressors, includes a support (16), a first arm (19) rotating with respect tothe support (16), a second arm (22) rotating with respect to the first, a Vee-shaped reference device (28) carried by the second arm, a measuring device (25,26,24,37,38) associated with the referencedevice, limiting devices (29,29',30,30') for limiting the rotations of the arms and thrust means (33) for keeping the reference device in contact with the pin in the course of the checking.A hydraulicactuator (13) displaces the apparatus (10) from a rest condition to a checking condition, in which the reference device (28) is in contact with the pin (8') to be checked, and vice versa.

Description

technical field [0001] The present invention relates to a device for checking the diameter of a substantially cylindrical eccentric portion of a mechanical part formed with a geometrical axis, the device comprising a substantially V-shaped reference during eccentric rotation of said portion around the geometrical axis device, which is adapted to cooperate with the eccentric part to be inspected, a measuring device moving together with the reference device, a support device for supporting the reference device and the measuring device, the support device comprising a support element, a a first rotatable connection element for rotation about an axis of rotation parallel to the geometric axis, a second rotatable connection element carrying the reference means and measuring means and connected to the first connection element for rotation about an additional axis parallel to the geometric axis and the axis of rotation The axis of rotation rotates relative to the first connecting ele...
