Abstract
The invention discloses calipers and method for measuring a w-shaped elastic strip. The calipers comprise a main gauge and a vernier caliper gauge; a locking screw is arranged on the vernier caliper gauge; a measuring claw of the vernier caliper gauge and the front end of the measuring claw of the main gauge are in the same plane; when the measuring claw of the vernier caliper gauge and the measuring claw of the main gauge are closed, the 0 scale lines of the main gauge and the vernier caliper gauge are aligned; the width of the front end of the measuring claw of the vernier caliper gauge is W. The calipers have the beneficial effects of being simple in structure, convenient to produce and manufacture, accurate in measurement result of which the error does not exceed 0.4mm, and convenient to operate; the stable buckling pressing force of the elastic strip product is ensured.
Description
Technical field
The present invention relates to a kind of ω type spring and measure slide calliper rule and measuring method, for measuring the distance between spring afterbody two minimum pressure points.
Background technology
For spring as shown in Figure 1, need to detect the size d between spring afterbody two minimum pressure points, due to not just the same about the side limb of this series products and the circular arc of middle limb formation, very inconvenient during measurement.During the size d of the original distance of the minimum pressure point of detection spring afterbody, be that product is placed on platform, utilize common slide calliper rule to be obtained by visual inspection, this measuring result error is large, easily occurs dispute.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of ω type spring and measuring slide calliper rule and measuring method.
The technical solution adopted for the present invention to solve the technical problems is: a kind of ω type spring measures slide calliper rule, comprises main scale and vernier scale, vernier scale is provided with lock screw; Vernier scale measuring claw and main scale measuring claw front end are positioned at same plane, when vernier scale measuring claw and main scale measuring claw close, and 0 scale mark alignment of main scale and vernier scale; The nose width of vernier scale measuring claw is W.
Present invention also offers a kind of ω type spring measuring method, comprise the steps:
Step one, spring is lain on measuring table, guarantee that spring is fixed after being close to platform by two afterbodys of spring;
Step 2, adjust loose lock screw moving cursor chi, main scale measuring claw is filled between measuring table and a measured circular arc of spring from outside, makes vernier scale measuring claw fill between another measured circular arc of measuring table and spring from inner side simultaneously;
Step 3, after guaranteeing that two measuring claws are close to platform and measured circular arc all simultaneously, tighten lock screw, guarantee that vernier scale is fixed on main scale, then the measurement data c that main scale shows is read, measurement data c is added the nose width W of vernier scale measuring claw, acquired results is the distance d between the minimum pressure point of spring afterbody two.
Compared with prior art, good effect of the present invention is: measure structure of calipers simple, be convenient to manufacture; Measurement result is accurate, and error is no more than 0.4mm, and easy to operate, ensure that spring product has stable buckle press.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is the side view of spring when being placed on platform;
Fig. 2 be this measurement slide calliper rule to zero time front view;
Front view when Fig. 3 is the use of this measurement slide calliper rule;
Fig. 4 is the enlarged diagrams of this measurement slide calliper rule when spring afterbody circular arc left and right radius difference 5mm.
Embodiment
A kind of ω type spring measures slide calliper rule, and as shown in Figures 2 and 3, comprising: main scale 1, vernier scale 2, lock screw 3, vernier scale measuring claw 4, main scale measuring claw 5 etc., wherein vernier scale 2 can move around along the scale mark direction of main scale 1; Vernier scale 2 is provided with lock screw 3, for regulating the degree of tightness of vernier scale 2 on main scale 1.Vernier scale measuring claw 4 and main scale measuring claw 5 front end are positioned at same plane, when vernier scale measuring claw 4 and main scale measuring claw 5 are completely closed, and 0 scale mark alignment of main scale 1 and vernier scale 2; The nose thickness of vernier scale measuring claw 4 and main scale measuring claw 5 is 0.3-0.6mm, and optimum thickness is that (if be greater than 0.6mm, for spring afterbody two sections of unequal situations of arc radius, then measuring error is excessive for 0.5mm; If be less than 0.3mm, then rigidity can not ensure, measuring claw is easily out of shape, and also can cause measurement result inaccurate); The nose width of vernier scale measuring claw 4 is W, and unit is millimeter, and W is more than or equal to 3 millimeters usually, too narrow, and rigidity can not ensure, measuring claw is easily out of shape.
Present invention also offers a kind of ω type spring measuring method, as shown in Figure 3, comprise the steps:
Step one, spring 7 is lain on measuring table, guarantee that spring is fixed after being close to platform by two afterbodys of spring;
Step 2, adjust loose lock screw 3 moving cursor chi 2, main scale measuring claw 5 is filled between measuring table and a measured circular arc of spring from outside, makes vernier scale measuring claw 4 fill in (outside, inner side are as shown in Figure 3) between another measured circular arc of measuring table and spring from inner side simultaneously;
Step 3, after guaranteeing that two measuring claws are close to platform and measured circular arc all simultaneously, tighten lock screw 3, guarantee that vernier scale 2 is fixed on main scale 1, then the measurement data c that main scale shows is read, measurement data c is added the nose width W of vernier scale measuring claw 4, acquired results is the distance d between the minimum pressure point of spring afterbody two.
In the practical measuring examples shown in Fig. 3, the measurement data c on the main scale of reading is 85.4 millimeters, and the nose width W of vernier scale measuring claw 4 is 5 millimeters, then the horizontal range d=85.4+5=90.4mm of the minimum pressure point of spring afterbody two.
When about spring afterbody, two sections of arc radius are respectively 35mm and 30mm (this is the modal range of size of spring), if the thickness of measuring claw front end is 0.5mm, as shown in Figure 4, then at 0.5mm place, about minimum pressure point, two sections of chord lengths are 5.9mm and 5.5mm, two sections, left and right chord length theory difference 0.4mm (i.e. 5.9-5.5), that is: the measuring error that the 0.5mm thickness had due to measuring claw front end produces can not more than 0.4mm.For the situation that two sections of arc radius about spring afterbody are equal, because about minimum pressure point, two sections of chord lengths are equal, the thickness that therefore measuring claw front end has can not produce measuring error.
