Description
Technical Field
The utility model belongs to engineering machine tool field, concretely relates to impeller blade surface profile detects instrument.
Background
Impeller class product, the during operation relies on rivers to pass through the blade and produces power, need to have stable water velocity and water flow, consequently, the profile deviation that requires the blade must not exceed 0.1mm, in impeller processing field, need detect the profile of every blade in order to control quality, current detection means need be equipped with professional testing personnel and use CMM equipment to detect, because detection efficiency is low, can't accomplish 100% detection, and detect the place and process the production place distance far away, also can't in time feed back product quality, discern the defective products that appear in the production process, consequently, current detection means is difficult to control product quality accurately high-efficiently.
Disclosure of Invention
The purpose of the invention is as follows: in order to overcome the defects in the prior art, the surface profile detection tool for the impeller blade is simple to operate, efficient and high in precision.
The technical scheme is as follows: in order to realize the above-mentioned purpose, the utility model provides an impeller blade surface profile detects instrument, including detecting ring, standard block and amesdial, the amesdial is installed on detecting the ring, the standard block is used for the amesdial to refer to zero setting, it is provided with at least one handle on the ring to detect, the handle is used for the drive to detect the ring and rotates on impeller blade surface.
Furthermore, a supporting block is arranged on the detection ring, a spring sleeve is sleeved on the supporting block, the spring sleeve is matched on a dial indicator, and the dial indicator is fixed on the detection ring.
Further, the dial indicator is fixed on the detection ring through a fastening screw.
Further, a positioning pin for positioning is arranged on the detection ring.
Furthermore, the number of the handles is two, and the handles are symmetrically arranged on the detection ring.
The design principle of the utility model is that: the standard block is used as a zero setting standard of the dial indicator, and the rotation of the detection ring on the surface of the impeller blade is utilized to convert the profile value of the surface of the blade into a scale value of the dial indicator, so that the profile value data can be conveniently, effectively and visually detected.
Has the advantages that: compared with the prior art, the utility model, through the cooperation design of detecting ring, standard block and amesdial, can acquire blade surface profile value through the scale interval of amesdial directly perceived, effective, high accuracy, break away from the reliance to measurement personnel specialty and equipment specialty, under the condition of having guaranteed the detection precision, very big improvement detection efficiency, reduced the detection degree of difficulty, can accomplish 100% and detect to reduce the defective rate by a wide margin, promoted whole product quality.

Detailed Description
The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.
As shown in fig. 1-3, the utility model provides an impeller blade surface profile detects instrument, including detecting ring 2, standard block 10 and amesdial 6, it is protruding down that detecting ring 2 is standard ring structure and bottom periphery, the top of detecting ring 2 is provided with supporting shoe 3, supporting shoe 3 passes through locking screw 4 to be fixed on detecting ring 2, spring housing 5 sets up in supporting shoe 3, amesdial 6 passes supporting shoe 3 and detects the annular ring of ring 2 respectively, 5 covers of spring housing are established on amesdial 6, still be provided with fastening screw 7 that is used for fixed amesdial 6 on the supporting shoe 3, the annular ring department of detecting ring 2 still is provided with the location slightly 8, the top symmetry of detecting ring 2 is provided with two handles 9.
In this embodiment, the detection tool is used to detect the surface profile of the impeller blade, and the specific operation flow is as follows:
1. firstly, the positioning pin 8 is inserted into an annular hole of the detection ring 2, wherein the size of the annular hole is phi 16H7, and the two are tightly assembled into a whole through a phi 16H7/p6 interference fit size;
2. inserting the positioning pin 8 into a ring hole matched with the standard block 10, wherein the ring hole is phi 25.35 +/-0.012, and rotating the surface of the dial indicator 6 until the pointer is aligned with the zero scale after the ring hole is stably placed;
3. taking out the detection ring 2, inserting and matching the positioning pin 8 on the surface of the blade of the impeller 1 to be detected, and rotating the detection ring 2 on the surface of the blade for a circle through the handle 9 after the detection ring is stabilized;
4. and observing the scale displayed by the pointer of the dial indicator 6, recording the maximum scale displayed by the pointer of the dial indicator 6, namely the actual size deviation value of the shape and contour of the impeller blade, judging that the detected impeller is a defective product if the actual size deviation value exceeds 0.1mm, and judging that the detected impeller is a qualified product if the actual size deviation value does not exceed 0.1 mm.
