Abstract
The invention discloses a special tool for measuring the thickness of a mold wash layer for a large centrifugal roller. The tool not only is convenient to operate and saves time and labor, but also is accurate in measurement data. The measuring tool is formed by a ruler rod and an outer sleeve pipe sleeved on the ruler rod. One end of the ruler rod is provided with a hollow pipe head, the other end of the ruler rod is provided with a hanging ring, scales are marked on a side wall in the middle of the ruler rod, and an outer sleeve pipe wall is provided with a window corresponding to the scales of the ruler rod. A mode of combining the ruler rod and the outer sleeve pipe is adopted, and the special tool for measuring the thickness of the mold wash layer for the large centrifugal roller is simple in structure and convenient to operate, saves time and labor, is sensitive in touch after meeting with a sand layer, can be carried, is accurate in measured data, and fundamentally solves the problem that sand adhesion of an unpacking blank roller is caused by inaccuracy in measurement or the cost is large.
Description
Technical field
The present invention relates to a kind of tool for measuring thickness, refer in particular to the special measurement instrument of the thickness of coating layer of casting pattern.
Background technology
At casting field, all can scribble one deck dope layer on the casting pattern, the thickness of coating layer of different casting molds is different, and thickness of coating layer has specific requirement.Original dope layer is measured does not have an accurate instrument of measurement in the technique, the technician generally adopts the saw blade of band point to measure, first with saw blade one termination sharpening, during measurement coating is inserted in the saw blade termination before the measurement, pinching mark position ruler measurement after inserting with nail after measuring.But this traditional measuring method is measured very out of true, to measure inaccurate main cause be when measuring and cause, saw blade Jianzha County can prick into to layer of sand, can't measure real coating thickness, therefore is subjected to the impact of human factor very large, when measurement is inaccurate, if dope layer is partially thin, can cause the blank roller scab of unpacking, if dope layer is partially thick, increase the coating consumption, cause the waste on the cost.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of easy to operate, and are time saving and energy saving, the specific purpose tool that measurement data is measured the thickness of coating layer of large centrifugal roller casting mold accurately.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of large centrifugal roller mold wash layer thickness special measurement instrument, described survey instrument is made of scale bar and the outer tube that is sleeved on the scale bar, the front end of described scale bar is the hollow tube head, and the middle part sidewall of scale bar is marked with length greater than the scale of thickness of coating layer; Position corresponding with the scale on the scale bar on the described overcoat tube wall has penetrating form.
The further improvement of concrete structure of the present invention is: described scale bar middle part also is provided with the annular slot that radian is scale bar 3/4 circumference, the position that described outer sleeve inner wall is relative with annular slot is provided with the limited block that matches with annular slot, this limited block and annular slot clamping.
The further improvement of concrete structure of the present invention is: the degree of depth of the blank pipe of the axial length of described annular slot and hollow tube head is all greater than the thickness of dope layer.
The further improvement of concrete structure of the present invention is: the front end of the hollow tube head of described scale bar front end is shaped with blade.
The further improvement of concrete structure of the present invention is: the rear end of described scale bar is provided with link.
Owing to adopted technique scheme, the obtained technical progress of the present invention is:
The mode that large centrifugal roller mold wash layer thickness special measurement instrument accepted scale bar of the present invention combines with outer tube, simple in structure, easy to operate, time saving and energy saving, feel was responsive after scale bar was run into layer of sand, measurement data is accurate, and can carry, and has fundamentally solved because measure inaccurate the unpack scab of blank roller or the large problem of cost of causing.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1, hollow tube head, 2, outer tube, 3, scale, 4, form, 5, annular slot, 6, scale bar, 7, link, 8, limited block.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further details:
Large centrifugal roller mold wash layer thickness special measurement instrument, this survey instrument is made of scale bar 6 and the outer tube 2 that is sleeved on the scale bar 6, the front end of described scale bar 6 is processed into hollow tube head 1, the degree of depth of the blank pipe of hollow tube head 1 is greater than the thickness of dope layer, have blade on the front end mouth of pipe of hollow tube head 1, this hollow tube head 1 structure can be very fast enter dope layer, feel is responsive after running into layer of sand, the rear end of scale bar 6 is provided with link 7, like this can be so that the technician carry, being marked with length at the middle part of scale bar 6 sidewall is 10mm scale (the coating thickness size is generally less than 10mm); Offer outside the penetrating form corresponding with scale bar 6 scales on the casing wall, form 4 axially vertical limit is corresponding with scale mark with outer tube, when the front end of the front end of scale bar 6 and outer tube 2 is in same plane, the zero graduation line of scale overlaps with the axial vertical limit of outer tube, and the length of scale 3 should be greater than thickness of coating layer.Side at scale bar 6 middle part scales 3 also is processed with annular slot 5, and the radian of annular slot 5 is 3/4 of scale bar circumference, and the axial length of annular slot 5 is greater than the thickness of dope layer.Described outer sleeve inner wall is provided with the limited block that matches with annular slot, this limited block and annular slot clamping.
During use, at first scale bar 6 is drawn in the outer tube, the front end of this survey instrument is placed on the measured dope layer, make the front end face of the hollow tube head 1 of scale bar 6 contact simultaneously the dope layer surface with the front end face of outer tube 2, the numerical value of the integer scale of the scale of the scale bar 6 that this moment record overlaps with a limit of the form of outer tube 2, if can record the numerical value of immediate integer scale mark when not having the accurate limit that overlaps, then technician one holds outer tube 2, repeatedly turn on the other hand scale bar 6, the hollow tube head 1 that makes scale bar 6 is back-outed and is entered dope layer from outer tube 2, after hollow tube head 1 is run into layer of sand, the technician has obvious sensation, the technician is feeling after the change in resistance, determine that hollow tube head 1 has penetrated dope layer, directly read the numerical value of scale this moment, and the difference between the numerical value of two scales is the thickness of dope layer.
