The specific embodiment
Be elaborated below in conjunction with the accompanying drawing specific embodiments of the invention.Should be understood that the specific embodiment described herein only is used for explanation and explains the present invention, is not limited to the present invention.
In the present invention, do not doing under the situation of opposite explanation, the noun of locality of use typically refers to reference to upper and lower, left and right shown in the drawings like " upper and lower, left and right "; " inside and outside " is meant inside and outside with respect to the profile of each parts itself.
Measuring method of the present invention comprises the axial displacement with respect to the mill housing 20 of universal mill of roll shaft 21 and/or the bearing 22 of detection level roll.
As stated, measuring the roll shaft 21 of horizontal roll or the axial displacement of bearing 22 is the axial displacement with respect to mill housing 20, and this measurement result has more the value of research and reference.
Wherein, can use various suitable contact measuring apparatus (hereinafter to be referred as measurement mechanism) to measure the axial displacement of roll shaft 21 or the bearing 22 of horizontal roll with respect to mill housing 20.
The measurement mechanism 30 that uses in explanation one embodiment of the present invention below.
Said measurement mechanism 30 comprises: installing plate 31; Be fixed on the scale 33 on this installing plate 31; Measuring stick 34 with said installing plate 31 pivot joints; Be used to regulate the positioning unit of the relative positioning of said installing plate 31 and said measuring stick 34, an end of said measuring stick 34 is provided with pointer, and the other end is provided with push rod 35.
During use; Measurement mechanism 30 is installed in through connector 10 on the mill housing 20 of universal mill and the roll shaft 21 or the bearing 22 of the horizontal roll through push rod 35 contact universal mills; To measure the axial displacement with respect to mill housing 20 of roll shaft 21 or bearing 22, this measurement result has more the value of research and reference.Particularly, when axial displacements took place for roll shaft 21 that is contacted when push rod 35 or bearing 22, measuring stick 34 pivoted and also drives the pointer that is positioned at measuring stick 34 1 ends and pivot, thereby the scale of the scale 33 that can point to after the throw of pointer is confirmed the size of axial displacement.
Preferably, said push rod 35 than said pointer more near the pivot points of said installing plate 31 and said measuring stick 34.For example, as shown in Figure 2, measuring stick 34 articulates through articulated part 39 (for example pivot) and installing plate 31, push rod 35 than pointer more near articulated part 39.Through this layout, the small axial displacement of push rod 35 will make the bigger amplitude of the beat of pointer, thereby represent small axial displacement with the form that ratio is amplified through the scale of pointed.
Wherein, positioning unit is used to regulate and keep the relative positioning of installing plate 31 and measuring stick 34.Particularly, measurement mechanism 30 is being installed to 20 last times of mill housing through connector 10, is making 0 graduation mark of pointed scale 33 through positioning unit.In other words, in installation process, positioning unit is used to make pointer to remain on 0.When roll shaft 21 or bearing 22 generation axial displacements, positioning unit can make pointer keep pointing to, so that read the scale of scale 33.Therefore, positioning unit can be various suitable structures, as long as can regulate and keep the relative positioning of installing plate 31 and measuring stick 34.
