Description
Technical field
It the utility model is related to a kind of ω types spring symmetry slide block type Quick detection tool.
Background technology
The method of inspection of symmetry index is excessively cumbersome in existing ω types spring, cannot quickly be examined in mass production
Survey, original detection method is as shown in Figure 1, first detecting left side size a1 using professional mould and vernier caliper and recording, so
After detect that right side and records size a2, number of the absolute value of a1-a2 as ω spring symmetries is calculated according to record result
Value, the numerical value are less than specified value for qualification.The measuring method is needed to carry out operator the training that vernier caliper uses and wanted
Operator is asked to be carried out at the same time record and calculating in measurement process.
The content of the invention
The shortcomings that the utility model overcomes in the prior art, there is provided a kind of ω types spring symmetry slide block type is quickly examined
Tool.
The technical solution of the utility model is：A kind of ω types spring symmetry slide block type Quick detection tool, including pedestal and set
Put origin reference location plate, reference axis and sliding block on pedestal；The reference axis is fixedly mounted on pedestal center line, the sliding block pair
Claim to be installed at left and right sides of reference axis, pointer is provided with sliding block, graduation mark corresponding with pointer is provided with pedestal.
Compared with prior art, the utility model has the advantages that：
Measurement procedure is simplified, spring coordinates dial scale using pointer afterwards in place, it is not necessary to using vernier caliper, is not required to
Calculated, whether the symmetry of spring can be directly measured using the amplitude of fluctuation of pointer is transfinited.
Brief description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is existing ω springs symmetry detects schematic diagram；
Fig. 2 is the structure diagram of this cubing.
Embodiment
A kind of ω types spring symmetry slide block type Quick detection tool, as shown in Fig. 2, including：Pedestal 1, tunable arrangement 2, reset
Compression spring 3, origin reference location plate 4, reference axis 5, sliding block 6, guide rail 7, pointer 8, graduation mark 9 etc., wherein：
Pedestal 1 is the carrying platform of all components；
Tunable arrangement 2 is installed on carrying platform, and the initial position of left and right sliding block can be adjusted；
Reseting pressuring spring 3 is sliding block reset compression spring, coordinates tunable arrangement to complete the calibration to sliding block initial position and sliding block
Automatically reset；
Positioning datum of the origin reference location plate 4 for spring when in place, is fixed on carrying platform；
Positioning datum when reference axis 5 is tested for spring, is fixedly mounted on carrying platform center line；
Sliding block 6 is slided by guide rail, drives pointer to indicate scale；
Guide rail 7 is sliding block movement guide rail；
Pointer 8 is fixedly mounted on sliding block 6, for indicating graduation；
Graduation mark 9 is indicated for scale.
Needed when being tested using the utility model to ω type spring symmetries first according to certain model spring width dimensions profit
Sliding block initial position (symmetrical calibration) has been demarcated with tunable arrangement, symmetry can be carried out to the type spring after the completion of calibration
Quick measurement, by the closely connected origin reference location plate of spring afterbody during inspection, with hand propelled spring by the left closely connected reference axis of limb in the middle part of spring,
Right side sliding block slides to the right under the promotion at the right limb edge of spring at this time, and spring is in place afterwards on the sliding block of observation right side pointed by pointer
Scale numerical value, writes down numerical value pusher and moves bar, by the right closely connected reference axis of limb in the middle part of spring (at this time right side sliding block will automatically reset with
Standby measurement next time), left slider slides to the left under the promotion at the left limb edge of spring at this time, and it is sliding to observe left side after spring is in place again
Pointer is directed toward scale numerical value on block, and just now on the sliding block of right side compared with scale numerical value pointed by pointer, the difference of left and right scale
Value is no more than setting and can determine that spring symmetry for qualification.Then take out spring, left slider due to spring taking-up and
Automatically reset.The measurement of subsequent product can then be carried out.
In order to more intuitively contrast scale pointed by pointer on the side slide of left and right at the same time, spring is promoted by left limb in the middle part of spring
Closely connected reference axis, at this time right side sliding block slided to the right under the promotion at the right limb edge of spring, after spring is in place, pass through adjustable dress
Put 2 right side slide position is fixed；Then spring is promoted, by the right closely connected reference axis of limb in the middle part of spring, left slider at this time
Slided to the left under the promotion at the left limb edge of spring, after spring is in place, while pointer is signified on paired observation left and right side sliding block
To scale numerical value, if the difference of the two is no more than setting and can determine that spring symmetry for qualification.Spring is then taken out, by two
Sideslip block reset, then can carry out the measurement of subsequent product.
Using cubing and method before, measurement is comparatively laborious, needs to record numerical value in measurement and is calculated, measurement knot
Fruit is influenced by measurement people using slide calliper rule ability, and due to that must be recorded and be calculated, adds the possibility of error.This
Utility model easily can be measured quickly for various sizes of ω types spring symmetry, directly contrasted left and right pointer and carved
The numerical value of degree, because contrast number is reduced to integer value by dial, it is not necessary to record and calculating can obtain symmetry difference,
Quick detection that is convenient and efficient, being particularly suitable in this kind of high volume production process of spring.
It is the left-right deviation based on spring center line that the utility model, which fully takes into account spring symmetry, the measuring device and
Measuring method all considers the measurement of the progress symmetry on the basis of the center line of spring completely, meets the type spring symmetry
Control requires.And the utility model, by pointer and graduation mark, the concrete numerical value that will be gone out with kind of calliper, is reduced to carve in the past
Angle value, eliminates the process of record and calculating, directly can draw difference range by contrast.
