Wherein, mill housing 20, for the framework of roll is installed, can be formed as connector 10 suitable structure, as long as can be suitable for, measurement mechanism 30 is installed on mill housing 20.
In one embodiment of the invention, as shown in Figure 1, described connector 10 can and comprise waist 11 and two shanks 12 for U-shaped, these two shanks 12 are connected to the two ends of described waist 11, described waist 11 is provided with the first connecting portion, each shank 12 is provided with the second connecting portion, and described waist 11 is connected with described measurement mechanism 30 by described the first connecting portion, and described shank 12 is connected with described mill housing 20 by described the second connecting portion.
Wherein, the first connecting portion and the second connecting portion can be various suitable connecting portions, as long as can be connected waist 11 with measurement mechanism 30 and be connected shank 12 and mill housing 20 by the second connecting portion by the first connecting portion.In the preferred embodiment of the present invention, described the first connecting portion can comprise and slips groove or multiple the first fastener hole 13, accordingly, measurement mechanism 30 can comprise the sliding connection plate 32 being arranged on installing plate 31 (explanation vide infra), in this sliding connection plate 32, can be provided with slip that groove or multiple the first fastener hole 13 coordinate at least one slip hole or chute.By this layout, can make measurement mechanism 30 adjustable grounds be connected to connector 10, then can regulate installation, measuring position with respect to mill housing 20.
Particularly, as shown in Figure 1, described waist 11 can be provided with multiple the first fastener holes 13, and the plurality of the first fastener hole 13 is arranged along the bearing of trend of described waist 11.Correspondingly, in sliding connection plate 32, be provided with chute, thereby such as, can make the measuring position of measurement mechanism 30 with respect to mill housing 20 Level tunes (regulating along left and right directions in Fig. 2) by the first securing member 15 (screw, bolt etc.) through one of them the first fastener hole 13.Selectively, described waist 11 can be provided with and slip groove, and this slips groove and extends along the bearing of trend of described waist 11.In sliding connection plate 32, can be provided with accordingly and slip corresponding at least one of groove with this and slip hole, thereby can make the measuring position of measurement mechanism 30 with respect to mill housing 20 Level tunes by the first securing member 15.
Described the second connecting portion can comprise at least one second fastener hole 14, can be provided with at least one installing hole corresponding at least one the second fastener hole 14 with this on mill housing 20.Selectable, as shown in Figure 2, also can shank 12 be press fit on mill housing 20 by suitable securing member (the second securing member 16).
In addition, by least one the second fastener hole 14, can more firmly be fixedly connected with mill housing 20 and measurement mechanism 30 by connector 10.Preferably, as depicted in figs. 1 and 2, be provided with second fastener hole 14 on one in described two shanks 12, on another, can be provided with two the second fastener holes 14, thereby make connector 10 and mill housing 20 stably fixing by 3.
Measurement mechanism 30 of the present invention can be various suitable contact measuring apparatus.The following describes the measurement mechanism 30 using in one embodiment of the present invention.
Described measurement mechanism 30 comprises: installing plate 31, be fixed on the scale 33 on this installing plate 31, measuring stick 34 with described installing plate 31 pivot joints, be used for the positioning unit of the relative positioning that regulates described installing plate 31 and described measuring stick 34, one end of described measuring stick 34 is provided with pointer, and the other end is provided with push rod 35.
When use, measurement mechanism 30 is arranged on the mill housing 20 of universal mill and contacts roll shaft 21 or the bearing 22 of the horizontal roll of universal mill by push rod 35 by connector 10, 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 displacement occurs for the roll shaft 21 contacting when push rod 35 or bearing 22, measuring stick 34 pivotables also drive and are positioned at the pointer pivotable of measuring stick 34 one end, thereby the scale of the scale 33 that can point to from throw of pointer is determined the size of axial displacement.
Preferably, described push rod 35 is than the pivot points of the more close described installing plate 31 of described pointer and described measuring stick 34.For example, as shown in Figure 2, measuring stick 34 for example, by articulated part 39 (pivot) and installing plate 31 pivot joints, and push rod 35 is than the more close articulated part 39 of pointer.By this layout, the small axial displacement of push rod 35 will make the amplitude that the beat of pointer is larger, thereby the form of amplifying with ratio represents small axial displacement by the scale of pointed.
Wherein, positioning unit is for regulating and keep the relative positioning of installing plate 31 and measuring stick 34.Particularly, in the time that measurement mechanism 30 is installed on mill housing 20 by connector 10, make 0 graduation mark of pointed scale 33 by positioning unit.In other words,, in installation process, positioning unit is used for making pointer to remain on 0.In the time that axial displacement occurs for roll shaft 21 or bearing 22, positioning unit can make pointer keep pointing to, to 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.
In a kind of preferred embodiment of the present invention, as shown in Figure 2, described positioning unit comprises fixed head 36, spring 37 and adjustment screw 38, described fixed head 36 is connected with described installing plate 31, one end of described spring 37 is connected with described measuring stick 34, and the other end is connected with described fixed head 31 by described adjustment screw 38.In installation process, can carry out the elastic force that regulating spring 37 applies measuring stick 34 by the screw-in position that regulates described adjustment screw 38, so that 0 of pointed.In measuring process, the elastic force of spring 37 can keep the sensing of pointer.
In addition, in installation process, in order to make push rod 35 can just contact roll shaft 21 or bearing 22, can make push rod 35 adjustable grounds be arranged on the other end of measuring stick 34.For example, preferably, as shown in Figure 2, the other end of described measuring stick 34 is provided with the screw extending transverse to described measuring stick 34, described push rod 35 has the screw thread coordinating with this screw, thereby can make push rod 35 just contact roll shaft 21 or bearing 22 by the screw-in position of controlling push rod 35.In addition, because the measurement end face of roll shaft 21 and bearing 22 is not conventionally in same level, thereby can be by regulating the horizontal level (regulating measuring position along the bearing of trend of measuring stick 34) of measuring stick 34 and controlling the axial displacement that roll shaft 21 or bearing 22 are optionally measured in the screw-in position of push rod 35.
Below describe by reference to the accompanying drawings the preferred embodiment of the present invention in detail; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition each the concrete technical characterictic described in above-mentioned detailed description of the invention, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible combinations.
In addition, between various embodiment of the present invention, also can be combined, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
