Abstract
The utility model discloses a rectangular sealing ring test tool. The rectangular sealing ring test tool comprises a rod-like inclined test tool body with a scale. A diameter of the test tool body becomes great gradually from up to down, and a tested sealing ring is sleeved on the test tool body and slides to be in clamping connection with the test tool body for matching at a certain position under the action of gravity. When the tested sealing ring is sleeved on the test tool body, and a pressure block which is sleeved on the test tool body like the tested sealing ring is placed on the tested sealing ring for pressing. The rectangular sealing ring test tool is advantaged in that: 1, a surface requirement of the test tool is high, so the rectangular ring almost without any deformation fits the test tool to acquire a relatively accurate measurement value under the action of the pressure block having certain weight; and 2, measuring precision of the test tool can reach 0.001 and can completely meet a tolerance requirement of 0.01.
Description
Technical field
The utility model relates to a kind of cubing, and more specifically, it relates to a kind of rectangular seal cubing.
Background technology
Rectangular seal is the critical component of brake system of car, and it is the braking ability that directly affects automobile, and a lot of failure modes have absolutely proved the importance of rectangular seal.A lot of means that detect rectangular seal size still rest on the vernier caliper stage at present, will have following inferior position: 1., because rubber parts has elasticity, while making to detect, deflection cannot be determined; 2. while measuring diameter dimension, without benchmark, cannot accurately find the center of circle accurately, thereby cannot obtain requiring size.3. due to the minimum precision grade 0.02 of vernier caliper, add people for estimating number, error can increase greatly.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, and check accuracy test is high, the rectangular seal cubing that measuring accuracy is high.
This rectangular seal cubing, comprise the bar-shaped cubing body with gradient and scale, it is large that the diameter of described cubing body becomes from top to bottom gradually, tested sealing snare with on cubing body and by Gravitational sliding, to a certain position, coordinate clamping with cubing body, when described tested O-ring seal is enclosed within on cubing body, tested O-ring seal top is also pressed with a briquetting being enclosed within equally on cubing body.
As preferably: described cubing body bottom is provided with base.
The beneficial effects of the utility model are: 1., because this cubing surface requirements is very high, the briquetting of adding constant weight is not almost having under deformation rectangular loop, thereby be fitted in, obtain measured value more accurately in cubing; 2. this cubing measuring accuracy can reach 0.001, can meet 0.01 tolerance completely.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Reference numeral: cubing body 1, briquetting 2, O-ring seal 3, base 4.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model is described in connection with preferred embodiment, should know, do not represent that the utility model is limited in described embodiment.On the contrary, the utility model is by alternative, modified and the equivalent contained in the scope of the present utility model that can be included in attached claims restriction.
Shown in Figure 1, this rectangular seal cubing, comprises the bar-shaped cubing body 1 with gradient and scale, and described cubing body 1 bottom is provided with base 4.The gradient of described cubing body 1 makes it more by lower diameter larger (it is large that the diameter of described cubing body 1 becomes from top to bottom gradually), and tested O-ring seal 3 overlaps and to a certain position, coordinates and block with cubing body 1 on cubing body 1 and by Gravitational sliding.When described tested O-ring seal 3 is enclosed within on cubing body 1, its top is also pressed with a briquetting 2 being enclosed within equally on cubing body 1.
The utility model, according to size tolerance requirements, changes into a kind of band gradient, the bar-shaped cubing of scale.Can directly read the size of O-ring seal 3, whether qualifiedly more can very easily pass judgment on rectangular seal 3, replace the inaccuracy in the past detecting with vernier caliper.The utility model structure as shown in Figure 1.Principal feature is tolerance to be directly transformed in the cubing with gradient, scale.Not only rational in infrastructure, simple, successful, more can reduce labour intensity, increases check accuracy test, more than measuring accuracy promotes several times.
During use: first rectangular seal 3 is put into surveyed area (tab area), then pushed down with about 20g left and right briquetting 2, cubing body 1 makes to fit.Then read 3 times scales along cubing body 1 of rectangular seal.Or can whether fall and whether in sensing range, evaluate qualified (in figure, marking out A) according to rectangular seal 3.
Claims (2)
1. a rectangular seal cubing, it is characterized in that: comprise the bar-shaped cubing body (1) with gradient and scale, it is large that the diameter of described cubing body (1) becomes from top to bottom gradually, and tested O-ring seal (3) cover is upper with cubing body (1) and to a certain position, coordinate clamping with cubing body (1) by Gravitational sliding; When tested O-ring seal (3) is enclosed within on cubing body (1), tested O-ring seal (3) top is also pressed with a briquetting (2) being enclosed within equally on cubing body (1).
2. rectangular seal cubing according to claim 1, is characterized in that: described cubing body (1) bottom is provided with base (4).
