Abstract
The invention discloses a special measurement device and a measurement method for omega-shaped elastic strips. The measurement device comprises a platform and a stand column, wherein the stand column is vertical to the upper working surface of the platform; a main scale which is capable of moving up and down along the stand column, is arranged on the stand column; a scale line direction of the main scale is vertical to the stand column; a vernier scale, which is capable of horizontally moving along the scale line direction of the main scale, is arranged on the main scale; and an arc center o of a measurement claw of the vernier scale, a zero scale line of the vernier scale, a zero scale line of the main scale and the side surface of the platform are arranged in the same plane. The special measurement device has the beneficial effect that the measurement device is simple in structure, convenient to product and manufacture, precise in measurement result with error being not greater than 1mm, convenient to operate and capable of ensuring that elastic strip products have stable fastening force.
Description
Technical field
The present invention relates to a kind of ω type spring special measurement device and measuring method, be used in particular for the measurement of circular arc peak apart from spring afterbody horizontal range.
Background technology
For spring as shown in Figure 1, need to detect the middle part 11 circular arc peaks of spring to the size of afterbody 12, because the height of both sides limb 13 circular arcs of this series products is all Dayu or the height that equals middle part circular arc, the radius of the two sections of circular arcs in peak left and right of middle part circular arc is different again, observes very inconvenient when measurement.While originally detecting middle part circular arc peak to the size of afterbody, be that product is placed on platform, utilize slide calliper rule and height gauge conjunction measuring, then obtain by visual inspection, this measuring result error is large, causes product buckle press unstable.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of ω type spring special measurement device and measuring method.
The technical solution adopted for the present invention to solve the technical problems is: a kind of ω type spring special measurement device, comprises platform and the vertically disposed column of upper workplace with platform; On column, be provided with the main scale that can move up and down along column, the scale mark direction of main scale is vertical with column; On main scale, be provided with the vernier scale that can move horizontally along the scale mark direction of main scale, the o of center of arc of the measuring claw of described vernier scale and the zero graduation line of vernier scale, the zero graduation line of main scale and the side of platform are at same plane.
The present invention also provides a kind of measuring method of ω type spring, comprises the steps:
Compared with prior art, good effect of the present invention is: measurement mechanism is simple in structure, be convenient to manufacture; Measurement result is accurate, and error is no more than 1mm, and easy to operate, has guaranteed 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:
Vertical view when Fig. 1 is the use of this measurement mechanism;
Fig. 2 is the front view of this measurement mechanism;
Front view when Fig. 3 is the use of this measurement mechanism;
Fig. 4 is the structure for amplifying schematic diagram of the measuring claw of this measurement mechanism.
Embodiment
A kind of ω type spring special measurement device, as shown in Figure 2 and Figure 4, comprising: column 1, lock screw 2, gib screw 3, platform 4, vernier scale 5, main scale 6, lock screw 7 etc.Column 1 is fixed on platform 4 by gib screw 3, column 1 is vertical with the workplace of platform 4, main scale 6 can move up and down along column 1, lock screw 2 is for regulating the degree of tightness of main scale 6 on column 1, the scale mark direction of main scale 6 vertical with column 1 (being that the scale mark direction of main scale 6 and the upper workplace of platform 4 are parallel), vernier scale 5 can move horizontally along the scale mark direction of main scale 6, lock screw 7 is for regulating the degree of tightness of vernier scale 5 on main scale 6, the o of center of arc of the measuring claw 9 of vernier scale 5 and 0 scale mark of vernier scale 5, 0 scale mark of main scale 6 and the side of platform 4 are at same plane.
As shown in Figure 4, the height h of measuring claw equals arc radius R for the shape of measuring claw 9 and structure, is 2 to 4mm, and taking 3mm as best, (if this numerical value is too large, such as exceeding 4mm, measuring error is larger; If too little, such as being less than 2mm, while measurement, be not easy to judge whether two tips of measuring claw all contact with the measured circular arc of spring).
The present invention also provides a kind of measuring method of ω type spring, as shown in figures 1 and 3, comprises the steps:
In this practical measuring examples shown in Fig. 3, the measured circular arc peak of spring is apart from the horizontal range d=41.5 ± 1mm of spring afterbody.
