According to the callipers disclosed by the utility model, whether the size of the welding leg meets the requirement is judged by comparing the sizes of radiuses of the arcs, which are formed by the welding legs. The callipers for measuring the welding leg, which is designed by the concept, is simple in structure and low in cost; special requirements on materials are avoided; and the callipers can be equipment for each worker, thereby better controlling the welding quality.
Description
Technical field
The present invention relates to a kind of slide calliper rule of measuring leg, particularly a kind of slide calliper rule of measuring leg through convexity.
Background technology
At present, had the slide calliper rule that leg is measured on the market, but this slide calliper rule price comparison is high.Accounting for whole workmans' 1/3 shipbuilding enterprise for welder's number, generally can only measure slide calliper rule for quality inspector or supvr are equipped with leg, can not be that all welders are equipped with.Therefore, the welder can not better control the size of leg in process of production, leg problem bigger than normal or less than normal occurs through regular meeting, influences acceptance of materials of ship.
The utility model content
The utility model provides a kind of cost low, easy to use, can more accurately measure the leg slide calliper rule of leg size.
A kind of leg of the utility model is measured slide calliper rule; Comprise rectangular body; At least one end angle of rectangular body is provided with the circular arc that caves inward; Arc angle is smaller or equal to 90 °; Arc radius
wherein, K is the length of side of leg that need to measure.
As preferred version, four of rectangular body end angles are respectively arranged with the circular arc that radius R is 5.065mm, 5.878mm, 6.69mm, 7.504mm, and institute is respectively 5mm, 6mm, 7mm, 8mm to the deserved leg length of side K of measurement that needs.
As other a kind of preferred version, four of rectangular body end angles are respectively arranged with the circular arc that radius R is 8.317mm, 5.065mm, 9.944mm, 10.75mm, and institute is respectively 9mm, 10mm, 11mm, 12mm to the deserved leg length of side K of measurement that needs.
The utility model judges through the size of the radius of comparison leg formation circular arc whether the leg size meets the requirements.It is simple in structure to measure slide calliper rule with the leg of this thinking design, and material does not have specific (special) requirements, and is with low cost, can guarantee that each workman can be equipped with, thereby can better control welding quality.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described.
Fig. 1 convexity synoptic diagram;
Fig. 2 embodiment 1 synoptic diagram;
Fig. 3 embodiment 2 synoptic diagram.
Embodiment
As shown in Figure 1, the workpiece that fillet weld connects is vertical relation mostly, therefore can calculate the radius of the circular arc of leg formation according to the computing formula of mutually perpendicular geological theorems in the adjacent both sides of rectangle and convexity Δ Z.Use for reference pattern detection method commonly used, the radius of the circular arc that forms through the comparison leg can judge whether the leg length of side meets the requirements.
As shown in Figure 1, the radius R=a+ Δ Z of the circular arc that leg forms.Wherein, according to related request convexity Δ Z≤1mm+0.15a; K is the length of side of leg according to the mutually perpendicular geological theorems in the adjacent both sides of rectangle
.Therefore, the radius of the circular arc of leg formation
Based on above principle; A kind of leg of the utility model is measured slide calliper rule; At least one end angle of rectangular body is provided with the circular arc that caves inward; The angle of circular arc is smaller or equal to 90 °; The radius of circular arc
wherein, K is the length of side of leg that need to measure.In use, the circular arc of circular arc on the slide calliper rule and leg is compared, can judge whether whether the radius of the circular arc that leg forms consistent with the arc radius of measuring slide calliper rule, and then judge whether the leg length of side meets the requirements.On the rectangular body of leg measurement slide calliper rule, circular hole 1 can be set, pass, be convenient for carrying to make things convenient for suspension member.
Because in the boats and ships production run, the length of side K of most of legs concentrates between 5 to 12mm, and therefore following is preferred two embodiment:
As shown in Figure 2; A kind of leg of the utility model is measured slide calliper rule; Comprise rectangular body; On four end angles (5,6,7,8) of rectangular body, be disposed with the circular arc that radius R is 5.065mm, 5.878mm, 6.69mm, 7.504mm, its pairing leg length of side K that measures that needs is respectively 5mm, 6mm, 7mm, 8mm.
The calculating reasoning process is following:
K＝5mm ΔZ≤1+0.15x3.535＝1.530
K＝6mm ΔZ≤1+0.15x4.242＝1.636
K＝7mm ΔZ≤1+0.15x4.949＝1.742
K＝8mm ΔZ≤1+0.15x5.656＝1.848
Therefore:
During K=5mm, radius of the radian R=1.530+3.535=5.065mm
During K=6mm, radius of the radian R=1.636+4.242=5.878mm
During K=7mm, radius of the radian R=1.742+4.949=6.69mm
During K=8mm, radius of the radian R=1.848+5.656=7.504mm
Embodiment 2
As shown in Figure 3; This practical a kind of leg is measured slide calliper rule; Comprise rectangular body; On four end angles (9,10,11,12) of rectangular body, be disposed with the circular arc that radius R is 8.317mm, 5.065mm, 9.944mm, 10.75mm, the pairing leg length of side K that measures that needs is respectively 9mm, 10mm, 11mm, 12mm.
The calculating reasoning process is following:
K＝9mm ΔZ≤1+0.15x6.363＝1.954
K＝10mm ΔZ≤1+0.15x7.07＝2.061
K＝11mm ΔZ≤1+0.15x7.777＝2.167
K＝12mm ΔZ≤1+0.15x8.484＝2.273
Therefore:
During K=5mm, arc radius R=1.530+3.535=5.065mm
During K=6mm, arc radius R=1.636+4.242=5.878mm
K＝7mm r(max)＝1.742+4.949＝6.69mm
K＝8mm r(max)＝1.848+5.656＝7.504mm
During K=9mm, arc radius R=1.954+6.363=8.317mm
During K=10mm, arc radius R=2.061+7.07=9.131mm
During K=11mm, arc radius R=2.167+7.777=9.944mm
During K=12mm, arc radius R=2.273+8.484=10.75mm
