Description
Technical field
The utility model relates to a kind of test fixture, specifically a kind of adjustable irregular solid of revolution barycenter eccentric testing frock.
Background technology
Along with developing rapidly of machinery industry, solid of revolution is widely used in ship equipment, engineering machinery, light industry and machinery, metallurgical machinery, medical machinery, industrial machinery people, rock tunnel(ling) machine, revolving stage lamp industry.
Solid of revolution, before dispatching from the factory, needs to detect the load-bearing capacity of solid of revolution and the serviceable life of solid of revolution, to judge the load-bearing capacity of solid of revolution.Existing detection mode is all be assembled to by swing bearing on some special use equipment to detect, and not only installation process is complicated, and cost is higher, and due to the technical parameter of distinct device different, testing result is not very reliable.
Measurement bay is the basis of installing all test fixtures, for the measured piece that appearance difference is larger, product test frock is difficult to accomplish completely general sometimes, so concerning a barycenter eccentric testing equipment, it is unavoidable that frock is changed, but need when design and in-process measurement frame the interchangeability fully taking into account frock, as long as it is identical to ensure often to organize frock interface, just can match with measurement bay.The basis that measurement bay provides L0 measuring basis to install simultaneously, measure because a part for barycenter test data comes from L0, and the conversion between product coordinate system and instrument coordinates system, so, the positioning precision of measurement bay processing directly can affect the accuracy of L0 test, and therefore the processing of measurement bay needs strict guarantee tolerance.
Utility model content
The purpose of this utility model be to provide a kind of structure simple, measure adjustable irregular solid of revolution barycenter eccentric testing frock easily, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of adjustable irregular solid of revolution barycenter eccentric testing frock, comprise measurement bay, guide pass, liftable V-type frame, support V-type frame, eccentering arm, eccentric gauge head and barycenter gauge head, described guide pass is provided with two, two guide pass are positioned at front side and the rear side of measurement bay, described liftable V-type frame is slidably mounted between two guide pass on the left of measurement bay, supporting V-type frame is slidably mounted between two guide pass on the right side of liftable V-type frame, described eccentering arm is arranged on the dead ahead of measurement bay, described eccentric gauge head is arranged on the below of eccentering arm, described barycenter gauge head is arranged on the bottom of measurement bay, the outside at four angles of described measurement bay is provided with column, described column is provided with rotary block.
As further program of the utility model: the top of described liftable V-type frame and support V-type frame is equipped with roller.
As further program of the utility model: described liftable V-type frame is also provided with lifting regulating mechanism.
As the utility model further scheme: the surface of described liftable V-type frame and support V-type frame is equipped with the non-metallic material bed of material.
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, easy to use, and the supporting construction on support V-type frame and the liftable governor motion on liftable V-type frame make it adapt to the solid of revolution to be measured of the required different diameter shell of column measured, and are widely used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1, a kind of adjustable irregular solid of revolution barycenter eccentric testing frock, comprise measurement bay 1, guide pass 2, liftable V-type frame 3, support V-type frame 4, eccentering arm 5, eccentric gauge head 6 and barycenter gauge head 7, described guide pass 2 is provided with two, two guide pass 2 are positioned at front side and the rear side of measurement bay 1, described liftable V-type frame 3 is slidably mounted between two guide pass 2 on the left of measurement bay 1, supporting V-type frame 4 is slidably mounted between two guide pass 2 on the right side of liftable V-type frame 3, liftable V-type frame 3 and support V-type frame 4 all can move at equipment axial direction, and can lock, liftable V-type frame 3 and the top supporting V-type frame 4 are equipped with can the roller 8 of smart scroll, described liftable V-type frame 3 is also provided with lifting regulating mechanism 9, described eccentering arm 5 is arranged on the dead ahead of measurement bay 1, described eccentric gauge head 6 is arranged on the below of eccentering arm 5, described barycenter gauge head 7 is arranged on the bottom of measurement bay 1, the outside at four angles of described measurement bay 1 is provided with column, described column is provided with rotary block, the surface of described liftable V-type frame 3 and support V-type frame 4 is equipped with the non-metallic material bed of material, during guarantee support product, product surface is not scratched.
Described measurement bay 1 welds a framework with section bar, then survey two and process guide pass 2, supporting construction on described support V-type frame 4 and the liftable governor motion on liftable V-type frame 3 make it adapt to the solid of revolution to be measured of the required different diameter shell of column measured, barycenter gauge head 7 and be installed on measurement bay 1 outstanding go out eccentering arm 5 to be used for the matter that the survey time turns inclined, eccentering arm 5 is below provided with eccentric gauge head 6, is used for ballast sensor.
Four columns are installed in the outside at described measurement bay 1 four angles; each column there is a rotatable block; survey matter inclined time block is inwardly rotated; it is made to be in the below of measurement bay 1; dog height mixes up in advance and makes itself and measurement bay 1 when surveying matter and being inclined at a distance of about 5mm, namely can drop on to shield on block once there is rollover measurement bay 1, when surveying barycenter by block to inner rotary; block is no longer in below measurement bay 1, and at this moment decline measurement bay 1 can not be pressed onto on block.
When measurement matter is inclined, measurement bay 1 is made to be in most high state by lifting regulating mechanism 9, then need solid of revolution be contained in liftable V-type frame 3 and support V-type frame 4, by lifting regulating mechanism 9, measurement bay 1 is declined again, pull change lever that throw-over gear is in and survey the inclined state of matter, after completing, decline measurement bay 1 drops in eccentricity sensor and the support of matter offset tool mouth, now equipment is in and surveys the inclined state of matter, gather eccentricity sensor reading now, be that mark carries out at the every 90 ° of misalignment measurements carrying out once bullet of the radial direction of bullet by the angle of solid of revolution empennage nature distinguish, gather eccentricity sensor reading now, rotate three times, carry out the measurement of circumferencial direction four angles altogether, each rotation all needs the sensor reading gathered at that time, after completing, program computation goes out eccentricity and the eccentric angle of solid of revolution, rise measurement bay 1 after completing.
The utility model structure is simple, easy to use, and the supporting construction on support V-type frame 4 and the liftable governor motion on liftable V-type frame 3 make it adapt to the solid of revolution to be measured of the required different diameter shell of column measured, and are widely used.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
