Abstract
The utility model discloses a measurer for a roller diameter. The utility model is mainly composed of a rule supporter (2), contact heads (1) and a length measuring meter (4). Both sides of the rule supporter (2) are lower than the middle part, and a measuring head (3) of the length measuring meter (4) is downwards installed in the middle of the rule supporter (2) vertically. The two contact heads (1) are installed below the ends of two side arms of the rule supporter (2) by using the measuring head (4) as a symmetry axis. When the measurement is made, the rule supporter (2) is arranged on a roller surface and is perpendicular to the axial line of the roller (6) to be measured. The two contact heads (1) simultaneously contact the roller surface, and the value of the roller diameter can be directly read on a dial of the length measuring meter (3) immediately. The measurer for the roller diameter has the advantages of small size, light weight, convenient operation, large measuring range, visual and convenient measurement, time saving and labour saving.
Description
The utility model relates to a kind of roller cable diameter gauge, is mainly used in the used major diameter working roll of roll, particularly cold hot-strip and the roller of backing roll and directly measures.
In the prior art, adopt outside micrometer breaker roll diameter to measure mostly.Because the outside micrometer volume is big, Heavy Weight, measure to get up to waste time and energy, extremely inconvenient, and also usually owing to misoperation, micrometer stand falls rapidly, causes roller surface damage and outside micrometer measuring head wolfram steel partial crushing.Chinese patent application CN95226339.4 relates to a kind of roll reconditioning precision chi, form by M type chi frame and the meter and the pivot pole that are equipped with on it, owing to there is not fixing position relation between the measuring head of two pivot poles and meter, therefore can only measure relative value, be used for the measurement of roll pairing or face of cylinder out-of-roundness, not this absolute value of energy measurement roller diameter.
The purpose of this utility model provides that a kind of volume is little, in light weight, the roller cable diameter gauge of easy operating.
The purpose of this utility model is to realize like this.
A kind of roller cable diameter gauge, mainly form by chi frame, contact head and linear measure longimetry table, the two side of chi frame is lower than the middle part, and linear measure longimetry table measuring head is installed in the middle part of chi frame vertically downward, and two contact heads are that axis of symmetry is installed in below, chi frame two side arms end with the measuring head.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing is the structure principle chart of the utility model roller cable diameter gauge.
The utility model utilizes 3 these principles of circumference of determining unique diameter, by measuring Convexity on certain chord length draws measured diameter. Because two contact heads 1 and type length meter 4 Gage outfit between have fixing position relationship. Distance between two contact heads, 1 end points namely Be a fixing chord length L, and type length meter 4 is by its gage outfit 3 measured length The convexity t of tested roll 6 on above-mentioned fixedly chord length L. As shown in the figure, the diameter D of roll 6 And following relation is arranged between chord length L and the convexity t:
(D/2)
2＝(L/2)
2+(D/2-t)
2
D＝t+L
2/4t
Because L is definite value, D and t have one to one relation. Long according to required precision Degree meter 4 can adopt amesdial or dial gauge, through dial scale is redefined, and can Directly reading roller from dial plate directly is worth. Also can adopt the inner number that has with displacement transducer According to the digital measurement table of processing capacity, tested roller directly is worth directly shows.
Oversize size and the weight that has then increased measuring instrument of distance L between the end points of two contact heads 1, the too little measuring accuracy that influences again.Generally selecting the distance L between two contact heads, 1 end points is 1/4～3/4 of tested roll 6 diameter D, i.e. L=(1/4～3/4) D.Contact head 1 adopts the higher high-abrasive material of hardness to make, and scratches roll surface for preventing it, and the end that contacts with roll surface is a sphere.For guaranteeing the precision of roller cable diameter gauge, need regularly it to be carried out gauging calibration, therefore, have at least one to be can be in two contact heads 1 along the adjustable contact head of regulating with respect to chi frame 2 from axis.
Introduce an embodiment of the present utility model below.
As shown in the figure, the utility model roller cable diameter gauge mainly is lower than the dihedral chi frame 2 at middle part by two side arms, and front end is that the contact head 1 and the dial scale of sphere formed through the clock gauge 4 that redefines.Clock gauge 4 measuring heads 3 are installed in the middle part of chi frame 2 vertically downward, and two contact heads 1 are that axis of symmetry is installed in below, end, chi frame 2 two side by threaded connection hole with the measuring head 3 of clock gauge 4.The adjustable contact head of one of them contact head for regulating with respect to chi frame 2 along himself axis.It is the opening of two of front and back with chi frame end portion subdivision that the threaded connection hole place that adjustable contact is installed on the chi frame 2 has this threaded hole of rip cutting, two screw 5 before and after the threaded connection hole outside is equipped with and is connected.Tighten screw 5, can make adjustable contact head location.The seam installing and locating of another contact head 1 by himself thread head is in the threaded connection hole of chi frame 2.Distance L in the present embodiment between the two contact head end points is 600mm, and according to L=(1/4～3/4) D, under the condition that guarantees suitable measuring accuracy, the roller of its energy measurement footpath scope is 800mm≤D≤2400mm.
After measuring instrument installs, should at first carry out gauging calibration to it.During measurement, chi frame 2 is placed on the roll surface perpendicular to tested roll 6 axis, two contact heads 1 contact roll surface simultaneously, can directly be worth by directly reading roller on the dial plate of clock gauge 4.
The advantage that the utility model compared with prior art has is: little, the weight of volume Gently, easy operating; Tested roller footpath can directly be read by meter or show, intuitive and convenient, It is time saving and energy saving to measure; The range scope of application is big, not only can be used for roller diameter and measures, and also can Be used for the measurement of other large diameter cylinder.
