Description
Technical field
The utility model relates to the milscale technical field, relates in particular to the thick milscale of a kind of cap.
Background technology
The gauge of bolt head can be divided into three types, is respectively:
The first kind: bolt head 01 gauge of common dormant bolt, H size as shown in Figure 1.Bolt head gauge H is from the bolt head end face to nominal diameter size φ d and the distance of the virtual intersection of angle [alpha] face;
Second class: bolt head 02 gauge of special dormant bolt, P size as shown in Figure 2.Bolt head gauge P is from the bolt head end face to standard-required size φ D and the distance of the virtual intersection of angle [alpha] face;
The 3rd class: bolt head 03 gauge of cup head bolt, H size as shown in Figure 3.Bolt head gauge H is to the distance the head supporting surface from the bolt head end face.
Present metering system is:
Under the head of bolt head 01 the R fillet is arranged in the first kind situation, can't use vernier caliper to measure.Can only use the levelling of projector elder generation, choose φ d outline line and angle [alpha] outline line then, get its intersection, carry out its distance of projection measurement again.Measure every 3 minutes average time spent;
In the second class situation, measurement point is the virtual intersection of φ D and angle [alpha] face, also can't use vernier caliper to measure.Can only use the levelling of projector elder generation, look for the virtual intersection of φ D and angle faces then, carry out its distance of projection measurement again.Measure the 3 minutes average time spent;
In the 3rd class situation, measurement face is arc surface, can't use vernier caliper to measure equally.Can only use the levelling of projector elder generation, choose the head end upper thread and support upper thread, carry out its distance of projection measurement again.Measure every 1 minute average time spent.
As can be seen from the above the metering system of projector is measured as stock size, waste time and energy, and the operability extreme difference, it is extremely low to measure efficient, has had a strong impact on the processing cycle of part.
The utility model content
The purpose of this utility model provides the thick milscale of a kind of cap, is intended to solve the difficult problem of measuring of bolt head gauge in the prior art.
In order to realize above purpose, the technical scheme of the thick milscale of cap of the present utility model is as follows:
The thick milscale of cap, comprise the milscale blade of measuring scale, has the stiff end that aligns for the initial measured place of workpiece for measurement on the milscale blade, removable being fixed with for the measurement piece that the location workpiece for measurement is installed on the stiff end, measure piece and have the reference field corresponding with the zero-bit of measuring scale, offer the pilot hole that the bar portion for workpiece for measurement is passed on the reference field, and be provided with the edge, hole that cooperates with the initial measured place block of workpiece for measurement of being used for that is in position, pilot hole aperture at reference field.
Measure and to offer the mounting hole that inserts for the blade stiff end on the piece, be equipped with on the hole wall of mounting hole for measuring piece and be threaded in trip bolt on the described stiff end, described measurement piece is connected on the described stiff end by trip bolt is removable.
Offer on the described measurement piece for the bar portion that treats workpiece pass, to be installed in the installation gap in the described pilot hole, installation gap is in to be measured being communicated with away from a side of blade and with described mounting hole of piece.
The utility model is at the removable measurement piece that is fixed with of stiff end of blade, measure piece and have the reference field corresponding with the zero-bit of measuring scale, offer the pilot hole that passes for for the bar portion of workpiece for measurement on the reference field, and be provided with the edge, hole cooperate with the initial measured place block of workpiece for measurement of being used for that is in position, pilot hole aperture at reference field, in use, the part that workpiece for measurement exceeds reference field is exactly the part that workpiece for measurement need be measured, the gauge of this part can be measured very easily by the measurement scale on the blade, just can obtain the actual (real) thickness size of workpiece for measurement then by converting, therefore the utlity model has advantage simple in structure and easy to use, solved the difficult problem of measuring of bolt head gauge in the prior art.

Embodiment
The embodiment of the thick milscale of cap of the present utility model, extremely shown in Figure 6 as Fig. 4, the thick milscale of this cap is made of milscale blade 1 and measurement piece 2, milscale blade 1 has the stiff end 1-1 as measuring basis, stiff end 1-1 is plugged in and measures in the mounting hole of offering piece 2 sides, and is threaded with measurement piece 2 by the trip bolt 3 that wears on the mounting hole hole wall.Measure piece 2 and towards a side side of the measurement screw rod of milscale blade 1 be the reference field 2-1 corresponding with zero graduation line on the milscale blade 1, offer the pilot hole 2-2 that passes for the bar portion of workpiece for measurement at reference field 2-1, have the edge, hole that is in position, pilot hole 2-2 aperture on the reference field 2-1.Measuring the installation gap 2-3 that the side of piece 2 away from the stiff end 1-1 of milscale blade 1 offers connection pilot hole 2-2.
Present embodiment in use, the bar portion of workpiece for measurement passes installation gap 2-3 and packs among the pilot hole 2-2, and the edge, hole of pilot hole 2-2 is cooperated with the initial measured place block of workpiece for measurement, then measuring screw rod by precession makes workpiece for measurement be pressed in the hole of mounting hole along last, measure the thickness that workpiece for measurement exceeds reference field 2-1 part, obtain the gauge numerical value that needs by following conversion:
When measuring first kind bolt 01, can directly measure the P value, and the gauge H=P+M that the needs of workpiece for measurement are measured, utilize reduction formula M=(D-d)/2/tan (α/2), because D, d, three size numerical value of α are definite value, therefore can draw the M value of different size bolt, and then obtain the data of the size numerical value H of needs;
