Abstract
The utility model relates to a crankshaft edge roundness measuring instrument, in particular to an instrument for measuring roundness of an edge of a crankshaft journal; the crankshaft edge roundness measuring instrument is characterized by comprising an iron-made shell; a V-shaped groove is arranged at the bottom of the iron-made shell; a measuring dial indicator and a handle are installed on the top of the iron-made shell, wherein a measuring pointer of the measuring dial indicator extends into the V-shaped groove along the centre line of the V-shaped groove; the installation direction of the handle is parallel to the direction of the centre line of the V-shaped groove; and a compression nut is arranged on the iron-made shell corresponding to the measuring pointer. When the crankshaft edge roundness measuring instrument is used, the V-shaped groove of the crankshaft edge roundness measuring instrument is clamped on a main journal of a crankshaft; the position of the measuring pointer is adjusted; the handle is hold, so that the handle is vertically upward and is kept fixed to the greatest extent; then, measurement can be carried out; and the crankshaft edge roundness measuring instrument is convenient for use and accurate for measurement.
Description
Technical field
The utility model relates to a kind of bent axle prismatic roundness appearance, designs a kind of instrument that is used to measure the prismatic roundness of crankshaft journal especially.
Background technology
Bent axle is important part in the piston engine, and bent axle is to change the rectilinear motion that the fuel oil blast produces one of into vital part that rotatablely moves.
The size tolerance requirements of the king journal of bent axle and crank pin axle journal is tighter; In the process of cylindrical grinder machining crankshafts axle journal; Be prone to produce prismatic roundness; Wherein many is many with triangular and five ribs; Three prismatic roundness are that the circular arc by several different radiis is linked to be, and the size (
surveys) that records at an arbitrary position with outside micrometer all equates.When axle journal radially rotates a circle along crankshaft center line; Promptly formed (
survey+ε) circumscribed circle, and ε promptly is the prismatic roundness that produces in the process so.
Measure prismatic roundness for small-sized cylindrical component, use special-purpose V shape iron, can detect the result very soon.But, measure then very difficulty for the bent axle prismatic roundness of its axle journal of parts measurement of several tons of weights like this.
The utility model content
According to above deficiency of the prior art, the technical matters that the utility model will solve is: a kind of above-mentioned defective that solved is provided, the bent axle prismatic roundness appearance that can measure the prismatic roundness of crankshaft journal easily.
The utility model solves the technical scheme that its technical matters adopted: described bent axle prismatic roundness appearance; It is characterized in that: comprise iron housing; The bottom of iron housing has V-shaped groove, and the top is equipped with measures dial gauge and handle, and the surveyingpin of wherein measuring dial gauge stretches in the V-shaped groove along the center line of V-shaped groove; The installation direction of handle and the centerline direction of V-shaped groove parallel, and the position of corresponding surveyingpin is provided with gland nut on the iron housing.
One end of gland nut withstands on the surveyingpin, can regulate surveyingpin through the degree of tightness gland nut and stretch into the length in the V-shaped groove, to adapt to the bent axle of different sizes.
Described handle is installed on the iron housing through hold-down nut.
Before the measurement; Should the main bearing journal inclined oil hole of air that need to measure be removed burr; Remove the endoporus dirt with Steel bristle brush, endoporus blown clean with wind, and with towel with the main bearing journal wiped clean; Two V-arrangements of bent axle prismatic roundness appearance V-shaped groove are measured face and are also answered wiped clean, and coat very thin one deck machine oil in the above equably.
Measuring process does; On special-purpose verifying bench; The V-shaped groove of bent axle prismatic roundness appearance is stuck on a certain king journal of bent axle (or crank pin axle journal), regulates surveyingpin through gland nut and stretch into the length in the V-shaped groove, make the syringe needle of surveyingpin contact with king journal well; Subsequently with the hand steered handle of living, and make handle keep fixed vertically upward and as far as possible.During measurement, measure dial gauge, in one week of turning crankshaft, measure the maximum perpendicular stroke ha=2 ε of dial gauge this moment zero-bit.
The beneficial effect that the utility model had is: bent axle prismatic roundness appearance in use; The V-shaped groove of bent axle prismatic roundness appearance is stuck on the king journal of bent axle; Regulate the position of surveyingpin, and, make handle keep fixed can the beginning to measure vertically upward and as far as possible with buttressing handle; Easy to use, measure accurately.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, iron housing; 2, V-shaped groove; 3, measure dial gauge; 4, handle; 5, hold-down nut; 6, surveyingpin; 7, gland nut.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; The bottom of iron housing 1 has V-shaped groove 2; The top is equipped with measures dial gauge 3 and handle 4, and handle 4 is installed on the iron housing 1 through hold-down nut 5, and the surveyingpin 6 of wherein measuring dial gauge 3 stretches in the V-shaped groove 2 along the center line of V-shaped groove 2; The centerline direction of the installation direction of handle 4 and V-shaped groove 2 parallels, and the position of corresponding surveyingpin 6 is provided with gland nut 7 on the iron housing 1.
Before the measurement; Should the main bearing journal inclined oil hole of air that need to measure be removed burr; Remove the endoporus dirt with Steel bristle brush, endoporus blown clean with wind, and with towel with the main bearing journal wiped clean; Two V-arrangements of bent axle prismatic roundness appearance V-shaped groove 2 are measured face and are also answered wiped clean, and coat very thin one deck machine oil in the above equably.
Measuring process does; On special-purpose verifying bench; The V-shaped groove 2 of bent axle prismatic roundness appearance is stuck on a certain king journal of bent axle (or crank pin axle journal), regulates surveyingpin 6 through gland nut 7 and stretch into the length in the V-shaped groove 2, make the syringe needle of surveyingpin 6 contact with king journal well; Subsequently with the hand steered handle 4 of living, and make handle 4 keep fixed vertically upward and as far as possible.During measurement, measure 3 pairs of zero-bits of dial gauge, in one week of turning crankshaft, measure the maximum perpendicular stroke ha=2 ε of dial gauge 3 this moment, and ε is the prismatic roundness of measuring.
