Description
Technical field
The present invention relates to mechanical equipment installation field, light-duty block and installation method thereof that particularly a kind of large tube-like slewing axial float is measured.
Background technology:
The large tube-like slewings such as bowl mill must be measured axial float in installation process, and the correct measurement of axial float value is the important step that guarantees large tube-like slewing installation quality.
The axial float of general device is in axle head center, to establish a dial gauge to measure, because the end face of the tubular equipment such as bowl mill is hollow, the block of dial gauge can not be placed in center, conventionally need to do block at a rigid element of the interim installation of end face, during measurement, block must very stable guarantee measuring accuracy, because so the larger rigid element of large tube-like device diameters will very thickly just can make it more stable, this means that parts are very heavy, more complicated is installed, therefore, make the efficiency of measurement very low.Need to invent a kind of light-duty parts and do block.
Summary of the invention:
Object of the present invention is just to overcome above-mentioned the deficiencies in the prior art, and the light-duty block that provides a kind of large tube-like slewing axial float to measure, this block is lightweight, can guarantee the stability when the axial float that carries out large tube-like slewing is measured, thereby effectively guarantee measuring accuracy.
Another object of the present invention is to provide the installation method of the light-duty block of large tube-like slewing axial float measurement.
As above design, technical scheme of the present invention is: the light-duty block that a kind of large tube-like slewing axial float is measured, it is characterized in that: stop body is cored slab, respectively there is a bolt hole at block two ends, wherein one end is movable end, the stud bolt that movable end bolt hole passes is with regulating spring, and the other end is stiff end, and stiff end bolt hole is installed with bolt; Block and mounting are loaded into one, and dial gauge is fixed on mounting, and axial float is measured indicator bracket and is located on equipment center.
The installation method of the light-duty block that above-mentioned large tube-like slewing axial float is measured, it is characterized in that: block is fixed on to tubular equipment end, they should be across two flange bolt holes in diametric(al), make block center line through the tubular equipment end face center of circle, with movable end stud bolt and stiff end bolt, block is fixed in equipment end flange, stiff end bolt needs fastening firm, movable end stud bolt needs appropriateness to tighten, its elasticity needs the reading of dial gauge to verify, after block installation adjustment is qualified, axial float just can be installed and measure dial gauge, its pointer should point to stop-surface completely and locate in tubular equipment center.
Above-mentioned movable end bolt hole is slotted hole.
Above-mentioned stiff end bolt hole is circular hole.
The method of adjustment of above-mentioned movable end stud bolt is: first that stud bolt is suitably fastening, dial gauge is packed on mounting, make its pointed cylinder inner surface, rotate large tube-like slewing one circle, record dial gauge in 12 o'clock, 3 o'clock, 6 o'clock and 9 o'clock 4 positions reading, if the reading difference at 3 o'clock and 9 o'clock is less than 0.05mm, the reading difference at 12 o'clock and 6 o'clock is less than 0.05mm, and the value at 3 o'clock and 9 o'clock is greater than the value at 12 o'clock and 6 o'clock, and stud bolt is firm; If difference has surpassed 0.05mm, need double end to unclamp; If dial gauge pointer is motionless, need to unclamp stud bolt; If dial gauge reading is unstable, need fastening stud bolt.
Principle of work of the present invention is: when tubular equipment rotates, can produce elastic deformation, horizontal direction diameter can become greatly, and the diameter of vertical direction can diminish.If the solid power of stud bolt is excessive, diameter change conference due to cylinder when the rotation of tubular equipment is horizontal block makes block produce tension distortion, when rotation can make block pressurized because diameter diminishes when vertical, also can produce distortion, therefore can make to measure inaccurate.If stud bolt is fastening excessively loose, the block reading that can shake is unstable and inaccurate.When stud bolt fastening when suitable due to block quality gently and very flexible, the elastic deformation of small tubular equipment can be discharged by its movable end, thereby has removed block distortion to the impact of measuring.
Block of the present invention is lightweight, when the axial float that carries out tubular equipment is measured, what reflect is the RC axial float of equipment, and the impact of the elasticity sex change producing while having removed equipment rotation on axial float, make to measure more rationally, degree of accuracy is higher, thereby more improved equipment installment quality.
Accompanying drawing explanation:
Fig. 1 is the structural representation of block of the present invention;
Fig. 2 is the 1. portion enlarged drawing of Fig. 1;
Fig. 3 is that the A of Fig. 1 is to schematic diagram.
In figure: (hollow aluminium alloy plate, 5-stiff end bolt, 6-stiff end packing ring, 7-dial gauge, 8-clamping screw, 9-mounting, 10-mounting set bolt, 11-axial float are measured dial gauge, 12-tubular apparatus body, 13-vessel flange and flange bolt hole for 1-movable end stud bolt, 2-movable end packing ring, 3-regulating spring, 4-block.
Embodiment:
The light-duty block that large tube-like slewing axial float is measured, block body 4 is hollow aluminium alloy plates, its weight is very light.Respectively there is a bolt hole at block two ends, and wherein the bolt hole of one end is slotted hole, and its stud bolt passing 1 is called movable end with regulating spring 3, and the bolt hole of the other end is that circular hole is installed with bolt 5 and is not with spring to be called stiff end; For the installation qualification that checks block 4 whether 2 and 6 is packing ring, and dial gauge 7 is fixed on mounting 9 by clamping screw 8; Mounting 9 use mounting set bolts 10 are connected with block, and dial gauge 11 is to be erected at the dial gauge of measuring for axial float on equipment center.
The installation method of block of the present invention is: the end that block is fixed on to tubular equipment 12, they should be across two flange bolt holes in diametric(al), make block center line through the tubular equipment end face center of circle, with stud bolt 1 and stiff end bolt 5, block is fixed in end flange 13, stiff end bolt 5 needs fastening firm, stud bolt 1 needs appropriateness to tighten, and its elasticity needs the reading of dial gauge 7 to verify.
The method of adjustment of dial gauge 7 elasticities is: first that bolt 1 is suitably fastening, dial gauge 7 is arranged and put in place, make its pointed cylinder inner surface, rotate large tube-like slewing one circle, record dial gauge 7 in 12 o'clock, 3 o'clock, the reading of 4 positions such as 6 o'clock and 9 o'clock, if the reading difference at 3 o'clock and 9 o'clock is less than 0.05mm, the reading difference at 12 o'clock and 6 o'clock is less than 0.05mm, and the value at 3 o'clock and 9 o'clock is greater than the value at 12 o'clock and 6 o'clock, think that the firm power of bolt 1 is suitable, otherwise need be by tightening or release bolt 1 regulates the degree of tightness of block.Regulate main points: if difference has surpassed 0.05mm, illustrate that bolt 1 is tight a little, need to unclamp; If dial gauge pointer is motionless, illustrate that bolt 1 bolt is too tight, need to unclamp; If dial gauge reading is unstable, too pine of bolt 1 is described, need fastening.
After block installation adjustment is qualified, axial float just can be installed and measure dial gauge 11, its pointer should point to stop-surface completely and locate in tubular equipment center.In this way like this, when the axial float that carries out tubular equipment is measured, what reflect is the RC axial float of equipment, and the impact of the elasticity sex change producing while having removed equipment rotation on axial float, it is more reasonable to make to measure, and degree of accuracy is higher, thereby has more improved equipment installment quality.
