Abstract
The utility model provides an inner cone angle measuring appliance, which comprise a body (1), wherein cone-shaped verniers (2) are arranged at the two ends of the body (1); and cone angles of the verniers are 60 DEG and 74 DEG respectively. By adopting the technical scheme, the inner cone angle measuring appliance provided by the utility model has a simple structure and is convenient to operate, and whether inner cone angles of joint cores of hydraulic oil pipes are qualified or not can be measured only by inserting the cone-shaped verniers into the cone angles needing to be measured, so that the operability and the accuracy are improved.
Description
Technical field
The utility model belongs to a kind of survey instrument of hydraulic oil pipe joint core, and more specifically, the utility model relates to a kind of interior cone angle measuring utensil.
Background technology
At present, the hydraulic oil pipe joint in-core conical surface adopt the cone angle of 60 ° and 74 °, tolerance be ± 1 °.Caliber size has nine kinds, and use universal protractor usually or use projector to take measurement of an angle, mainly be the principle that adopts the outline line alignment.In adopting this metering system, there are two factors easily to produce bigger measuring error, the one, universal protractor has thickness, and the conical surface has radian, and the plane is to cambered surface, the surface of contact shakiness; Especially inner cone, conical surface bore are less than the joint core of 15mm, and universal protractor is measured and just can't be measured.Using projector one is that Measuring Time is oversize then, needs the location, gets a little, controls; The 2nd, need cutting products, operation is inconvenience extremely, and is uneconomical, is not suitable for long-term large batch of detection.Measure comparatively economically though cut model, it is also convenient to operate, only by sample the visual effect of plate and conical surface gap printing opacity judge product whether qualified obviously be inaccurate, inner cone especially.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of interior cone angle measuring utensil that improves applicability, reduces error is provided.
To achieve these goals, the technical scheme taked of the utility model is:
Provided by the utility model this in the cone angle measuring utensil, comprise body, be provided with vernier at the two ends of described body, described vernier be shaped as taper, cone angle is respectively 60 ° and 74 °.
Described vernier and body are hinged by swivel pin.
The measurement limit of described vernier is the inclined-plane.
Adopt technique scheme, this interior cone angle measuring utensil that the utility model provides, simple in structure, easy to operate, whether qualified as long as the vernier of taper is inserted into if going out hydraulic oil pipe joint in-core coning angle with regard to energy measurement in the cone angle of required measurement, improved operability and accuracy.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this instructions and the mark among the figure are made brief description:
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure:
1, body, 2, vernier, 3, swivel pin.
Embodiment
As shown in Figure 1, the utility model provides this in the cone angle measuring utensil, comprise body 1, be provided with vernier 2 at the two ends of body 1, vernier 2 be shaped as taper, cone angle is respectively 60 ° and 74 °.
Adopt technique scheme, be provided with vernier 2 at the two ends of body 1, vernier 2 be shaped as taper, cone angle is 60 ° and 74 °, whether qualified as long as the vernier 2 of taper is inserted into if going out hydraulic oil pipe joint in-core coning angle with regard to energy measurement in the cone angle of required measurement, improve the work efficiency of survey crew, also improved operability and accuracy simultaneously.
As described in Figure 1, vernier 2 is hinged by swivel pin 3 with body 1.
The measurement limit of vernier 2 is the inclined-plane.
Adopt technique scheme, vernier 2 is hinged by swivel pin 3 with body 1, and vernier 2 can rotate on body 1 with arbitrarily angled like this, and the side both sides of vernier 2 are the inclined-plane, guarantees measured cone angle and vernier 2 contacting better like this, guarantees the measurement quality.
The technical scheme that the utility model adopted compared with prior art, has tangible difference, possessed outstanding substantial characteristics, and obtained marked improvement technically, be worth in industrial promotion and application, so, the utlity model has novelty, creativeness and practicality.
Claims (3)
1. cone angle measuring utensil in a kind comprises body (1), it is characterized in that: be provided with vernier (2) at described body (1) two ends, described vernier (2) be shaped as taper, cone angle is respectively 60 ° and 74 °.
2. according to the described interior cone angle measuring utensil of claim 1, it is characterized in that: described vernier (2) is hinged by swivel pin with body (1).
3. according to claim 1 or 2 described interior cone angle measuring utensils, it is characterized in that: the measurement limit of described vernier (2) is the inclined-plane.
