Description
Technical field
The present invention relates to a kind of ω types spring measurement slide calliper rule and measuring method, for measuring two minimum pressure points of spring afterbody
The distance between.
Background technology
For spring as shown in Figure 1, it is necessary to the size d between two minimum pressure points of spring afterbody be detected, due to such
Circular arc that the side limb of product is formed with middle limb or so is not fully, very inconvenient during measurement.Originally detect spring afterbody most
It is that product is placed on platform during the size d of the distance of low pressure point, observes by the naked eye to obtain using common slide calliper rule, this survey
It is big to measure resultant error, easily disputes on.
The content of the invention
In order to overcome the disadvantages mentioned above of prior art, the invention provides a kind of ω types spring measurement slide calliper rule and measurement side
Method.
The technical solution adopted for the present invention to solve the technical problems is：A kind of ω types spring measures slide calliper rule, including main scale
And vernier scale, lock screw is provided with vernier scale；Vernier scale measuring claw and main scale measuring claw front end are generally aligned in the same plane, when
When vernier scale measuring claw and main scale measuring claw close, the 0 graduation mark alignment of main scale and vernier scale；The front end of vernier scale measuring claw is wide
Spend for W.
Present invention also offers a kind of ω types spring measuring method, comprise the following steps：
Step 1: spring is lain on measuring table, it is ensured that two afterbodys of spring fix spring after being close to platform；
Step 2: adjust loose lock screw moving cursor chi, main scale measuring claw is set to fill in measuring table and spring from outside
Between one measured circular arc, while vernier scale measuring claw is filled in another of measuring table and spring from inner side and be measured circle
Between arc；
Step 3: after ensuring two measuring claws while being close to platform and measured circular arc, lock screw is tightened, it is ensured that
Vernier scale is fixed on main scale, then reads the measurement data c shown on main scale, measurement data c is added into vernier scale measuring claw
Nose width W, acquired results are the distance between two minimum pressure point of spring afterbody d.
Compared with prior art, the positive effect of the present invention is：Measurement slide calliper rule are simple in construction, are easy to manufacture；Measurement
As a result accurate, error is no more than 0.4mm, and easy to operate, it is ensured that spring product has stable buckle press.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is that spring is placed on side view when on platform；
Fig. 2 is this measurement slide calliper rule to front view when zero；
Fig. 3 is front view when this measurement slide calliper rule use；
Fig. 4 is enlarged diagram of this measurement slide calliper rule when spring afterbody circular arc or so radius differs 5mm.
Embodiment
A kind of ω types spring measures slide calliper rule, as shown in Figures 2 and 3, including：Main scale 1, vernier scale 2, lock screw 3, vernier
Chi measuring claw 4, main scale measuring claw 5 etc., wherein vernier scale 2 can move back and forth along the graduation mark direction of main scale 1；On vernier scale 2
Lock screw 3 is provided with, it is elastic on main scale 1 for adjusting vernier scale 2.Vernier scale measuring claw 4 and the front end of main scale measuring claw 5
It is generally aligned in the same plane, when vernier scale measuring claw 4 and main scale measuring claw 5 close completely, 0 graduation mark pair of main scale 1 and vernier scale 2
Together；The nose thickness of vernier scale measuring claw 4 and main scale measuring claw 5 is 0.3-0.6mm, and optimum thickness is 0.5mm (if big
In 0.6mm, for two sections of unequal situations of arc radius of spring afterbody, then measurement error is excessive；If less than 0.3mm, then just
Degree cannot be guaranteed that measuring claw is easily deformed, and can also cause measurement result inaccuracy)；The nose width of vernier scale measuring claw 4 is W,
Unit is millimeter, and W, which is typically larger than, is equal to 3 millimeters, and too narrow, rigidity cannot be guaranteed, measuring claw is easily deformed.
Present invention also offers a kind of ω types spring measuring method, as shown in figure 3, comprising the following steps：
Step 1: spring 7 is lain on measuring table, it is ensured that two afterbodys of spring fix spring after being close to platform；
Step 2: adjusting the loose moving cursor chi 2 of lock screw 3, main scale measuring claw 5 is set to fill in measuring table and spring from outside
A measured circular arc between, while make vernier scale measuring claw 4 from inner side fill in measuring table and spring another is tested
Between amount circular arc (outside, inner side are as shown in Figure 3)；
Step 3: after ensuring two measuring claws while being close to platform and measured circular arc, lock screw 3 is tightened, really
Protect vernier scale 2 to be fixed on main scale 1, then read the measurement data c shown on main scale, measurement data c is surveyed plus vernier scale
The nose width W of measuring jaw 4, acquired results are the distance between two minimum pressure point of spring afterbody d.
In the practical measuring examples shown in Fig. 3, the measurement data c on the main scale of reading is 85.4 millimeters, vernier scale measuring claw 4
Nose width W be 5 millimeters, then the horizontal range d=85.4+5=90.4mm of two minimum pressure point of spring afterbody.
When two sections of arc radius of spring afterbody or so are respectively 35mm and 30mm (this is the most common size range of spring)
When, if the thickness of measuring claw front end is 0.5mm, as shown in figure 4, then at 0.5mm, two sections of chord lengths of minimum pressure point or so are
5.9mm and 5.5mm, the theoretical difference 0.4mm (i.e. 5.9-5.5) of two sections of left and right chord length, i.e.,：Have due to measuring claw front end
Measurement error is not over 0.4mm caused by 0.5mm thickness.For the equal situation of two sections of arc radius of spring afterbody or so,
Because two sections of chord lengths of minimum pressure point or so are equal, therefore the thickness that measuring claw front end has will not produce measurement error.
