Abstract
The utility model discloses a screw rotor measuring tool. At present, a three-coordinate measuring instrument is high in production cost and is incapable of realizing online measurement when being used for measuring a screw rotor. The screw rotor measuring tool disclosed by the utility model is composed of a first measuring plate and a second measuring plate which are connected into a whole, wherein the first measuring plate and the second measuring plate are respectively provided with a measuring curve, and the measuring curves are coincident with outlines of the cross section of a measured screw rotor. According to the screw rotor measuring tool, the screw rotor can be directly measured in the process of machining the screw rotor without the needs of being detached from a machining lathe and then being arranged on the three-coordinate measuring instrument, and therefore the screw rotor measuring tool is convenient to use and saves a great deal of work hour; and the screw rotor measuring tool is lower in the machining and manufacturing cost and beneficial to being popularized and applied in the screw pump manufacturing enterprises.
Description
Technical field
The utility model relates to survey instrument, and concrete is the screw rotor survey instrument.
Background technology
Screw pump is a kind of volumetric pump.The quality of screw pump performance depends on the manufacturing accuracy of the screw rotor in the pump, and the measurement of the end face molded lines that an important step of raising screw rotor manufacturing accuracy is exactly a screw rotor.Have only through measuring accurately, could confirm whether screw rotor reaches designing requirement.Present domestic screw pump manufacturer adopts three-coordinates measuring machine that screw rotor is measured mostly.Three-coordinates measuring machine is measured and is had two problems, and the one, cost an arm and a leg, improved production cost; The 2nd, can not on-line measurement, must unload and then be installed to screw rotor down three-coordinates measuring machine from lathe and measure, wasted a large amount of man-hours.
The utility model content
The technical matters that the utility model will solve and the technical assignment of proposition be overcome existing adopt three-coordinates measuring machine to screw rotor measure the production cost height, can not on-line measurement defective, provide a kind of can on-line measurement in process, survey instrument itself is made simply, cost is low screw rotor survey instrument.
For achieving the above object; The screw rotor survey instrument of the utility model; It is characterized in that: measure plate by the first measurement plate and second that is connected as a single entity and constitute; The said first measurement plate and second is measured on the plate and is all established the measurement curved surface, and the cross-sectional profiles line of described measurement curved surface and measured screw rotor matches.
As the optimization technique means: said first to measure plate parallel with the second measurement plate.The distance that the said first measurement plate and second is measured between the plate is the N*1/X of measured screw rotor pitch, and described X is a number of measured screw rotor, and described N is the natural number among the 1-3.The measurement curve form that the measurement curved surface of the said first measurement plate and second is measured plate is identical, and further, the measurement curved surface that the measurement curved surface of the said first measurement plate and second is measured plate coincides in the projection of axis direction.
The beneficial effect of the utility model is: can in the process of processing screw rotor, directly measure, not need to unload down and be installed to three-coordinate instrument again and measure from lathe for machining, and easy to use, saved a large amount of man-hours; The processing and manufacturing cost of screw rotor survey instrument itself is very low, is beneficial to screw pump manufacturing enterprise and applies.

Embodiment
Below in conjunction with Figure of description the utility model is further specified.
The screw rotor survey instrument 01 of the utility model; Shown in Fig. 3-4; It is to measure plate 12 by the first measurement plate 11 and second that is connected as a single entity to constitute; The first measurement plate 11 and second is measured all to establish on the plate 12 and is measured curved surface 13,14, and the cross-sectional profiles line 21 of measuring curved surface 13,14 and measured screw rotor 02 matches.
Concrete: it is parallel that the first measurement plate 11 and second is measured plate 12; The distance that the first measurement plate 11 and second is measured between the plate 12 is the N*1/X of measured screw rotor 02 pitch P, and X is a number of measured screw rotor, and N is the natural number among the 1-3; Measurement curved surface 14 shapes that the measurement curved surface 13 of the first measurement plate 11 and second is measured plate 12 are identical, and especially, the measurement curved surface 14 that the measurement curved surface 13 of the first measurement plate 11 and second is measured plate 12 coincides in the projection of axis direction.
Screw rotor survey instrument shown in Fig. 3-4 is a kind of version that is used to measure screw rotor shown in Fig. 1-2; In view of screw rotor shown in Fig. 1-2 is the single head structure; Therefore; Screw rotor survey instrument shown in Fig. 3-4; The first measurement plate and the second measurement plate are parallel, and the distance that the first measurement plate and second is measured between the plate is the pitch (obvious, the distance between the first measurement plate and the second measurement plate also can be 2 times perhaps 3 times of measured screw rotor pitch) of measured screw rotor; The measurement curve form that the measurement curved surface of the first measurement plate and second is measured plate is identical, and the measurement curved surface that the measurement curved surface of the first measurement plate and second is measured plate coincides in the projection of axis direction.
If tested screw rotor is double end, then first measure plate and second measure between the plate distance can for measured screw rotor pitch half the, 1 times perhaps 1.5 times; If tested screw rotor is three, then first measures plate and can be 1/3,2/3 or 1 times of measured screw rotor pitch with distance between the second measurement plate.
During measurement; Screw rotor survey instrument 01 is placed on the screw rotor 02; Make the measurement curved surface 13 of the first measurement plate 11, the measurement curved surface 14 of the second measurement plate 12 rely on the surface of screw rotor 02; At this moment, if screw rotor processing accurately, then first measure plate measurement curved surface, second measure the measurement curved surface of plate and the surface of measured screw rotor fits; If the processing of measured screw rotor is inaccurate; Then first measure the measurement curved surface of plate or/and second measure between the surface of measurement curved surface and measured screw rotor of plate and the slit can occur; Can record the size in slit through feeler gauge; Can readjust the depth of cut that turning is processed according to the size in slit, until processing the product that adheres to specification.
