Detailed Description
In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings and the detailed description.
The axial flow product outer diameter measuring device as shown in fig. 1 to 3 comprises a base 1, wherein a heightening bracket 11 is arranged on the base 1, a reference platform 2 is arranged at the upper end of the heightening bracket 11, a main shaft 3 which extends outwards and can be used for installing an axial flow product (namely fan blade) to be measured is rotatably connected to the lower surface of the reference platform 2, and a height ruler assembly 4 which can horizontally slide on the upper surface of the reference platform 2 is arranged on the upper surface of the reference platform 2.
More specifically, the height gauge assembly 4 comprises a counterweight sliding block 41 capable of sliding on the upper surface of the reference platform 2, a vertical main graduated scale 42 is arranged on the counterweight sliding block 41, a measuring claw 43 capable of lifting is arranged on the main graduated scale 42, the measuring claw 43 extends to the upper side of an axial flow product to be measured, and a fastening screw 44 and a height fine adjustment structure 45 are arranged between the measuring claw 43 and the main graduated scale 42. Here, the height fine adjustment structure 45 is a common structure, please refer to a height ruler, and will not be described herein.
In the measuring device of the utility model, the axial flow product to be measured needs to be mounted on the main shaft 3, so that the axial flow product to be measured can freely rotate. While the height gauge assembly 4 is placed on the reference platform 2 and is free to slide on the upper surface of the reference platform 2. During measurement, the axial flow product to be measured is slowly rotated by hands, and at least one full rotation is realized. The horizontal position of the height gauge assembly 4 is adjusted by manually pushing the counterweight slider 41 to slide on the upper surface of the reference platform 2 while rotating, and the height of the measuring claw 43 is adjusted by adjusting the fastening screw 44 and the height fine adjustment structure 45, so that the measuring claw 43 abuts against the highest point of the fan blade of the axial flow product to be measured. After the highest point is found, the scale value on the height rule assembly 4 is read, and then the maximum outer diameter of the axial flow product to be measured is twice of the read scale value.
The measuring device of the utility model brings a lot of convenience for measuring the axial flow products. First, from the viewpoint of operational convenience, it is very convenient to use the present utility model for measurement. The operator only needs to directly install the axial flow product to be measured on the main shaft 3, then manually rotate the axial flow product to be measured, and simultaneously adjust the position of the height gauge assembly 4, so as to ensure that the measuring claw 43 can accurately measure the highest point of the fan blade. The series of operation steps are simple and clear, and do not need complex setting and adjustment. More importantly, the measuring method does not need to search a reference, so that the detection time is greatly shortened. This undoubtedly reduces the complexity and experience requirements of the work for the inspector.
In addition to the convenience of operation, the measuring device of the present utility model also has excellent performance in terms of accuracy of measurement results. Because the axial flow product to be measured can rotate along with the main shaft 3, the height ruler assembly 4 can accurately find the highest point of the axial flow product to be measured. The design ensures high accuracy in the measuring process, avoids subjective errors of visual assessment, and accordingly accurately obtains the maximum outer diameter of the axial flow product to be measured. Furthermore, the utility model allows the operator to read the maximum radius of the axial flow product to be measured directly from the height gauge assembly 4, which makes the measurement data more accurate and reliable.
The heightening bracket 11 arranged between the base 1 and the reference platform 2 has the main function of improving the height of the device, thereby being capable of measuring large-scale axial flow products more conveniently.
The design of the reference platform 2 of the present utility model makes the measurement more accurate. The reference platform 2 is usually made of high-precision materials and by a machining process so as to ensure the surface of the reference platform to be flat and smooth, thereby ensuring the accuracy of measurement.
Preferably, the lowest position of the measuring jaw 43 is flush with the axis of the spindle 3. I.e. the zero position of the measuring jaw 43 is flush with the axis of the spindle 3. By adopting the design, the numerical value read on the height ruler assembly 4 is consistent with the maximum radius of the axial flow product to be measured, and the axial flow product can be directly read without conversion. Of course, the maximum diameter of the axial flow product to be measured is twice the value read.
More specifically, the lower surface of the reference platform 2 is provided with a spindle box 31, and at least two bearings 32 for rotationally connecting the spindle 3 and the spindle box 31 are arranged between them. The double bearing 32 design between the shaft 3 and the spindle box 31 has multiple advantages. First, the presence of the double bearing 32 significantly reduces the friction when the spindle 3 rotates, which makes the spindle 3 smoother during rotation. The smooth rotation not only reduces the abrasion of the main shaft 3 and prolongs the service life of the main shaft, but also ensures higher precision in the measuring process. In addition, the dual bearing 32 design also helps to increase the strength of the overall structure. In conventional single bearing designs, the spindle may generate large vibrations and offsets as it rotates, which not only affects the accuracy of the measurement, but may also cause damage to the device itself. However, the double bearing 32 design can effectively distribute these forces, reducing vibration and deflection, thereby ensuring stability of the spindle 3 during rotation.
More specifically, the spindle box 31 is provided with a mounting hole 311 for mounting the bearings 32, a gasket sleeve 33 is disposed between the two bearings 32, and the spindle 3 passes through the gasket sleeve 33. This design not only facilitates the installation of the bearing 32, but also ensures its stability and accuracy. In order to further enhance the stability and supporting effect of the spindle 3, a gasket sleeve 33 is skillfully arranged between the two bearings 32. The addition of the gasket sleeve 33 not only provides additional support for the spindle 3, but also helps to distribute stress and reduce wear, thereby extending the useful life of the spindle 3. It should be noted that the design of the washer sleeve 33 is smart in that it is located between the two bearings 32. This arrangement enables the washer sleeve 33 to cooperate with the bearing 32 when the spindle 3 rotates, providing a smooth and smooth rotating environment for the spindle 3. In the installation process, an operator may insert the spindle 3 into the washer sleeve 33 and the bearing 32 first, and then insert the three into the installation hole 311 of the spindle box 31 in sequence. The installation mode is simple and easy to operate, and the assembly efficiency is greatly improved.
More specifically, the end of the spindle 3 is provided with a fixing nut 34 for locking the axial flow product to be tested. By means of the fixing nut 34, the operator can quickly fix the axial flow product to be measured on the spindle 3 and ensure that it does not slip or move during the measurement. Likewise, when the measurement is completed, the operator can rapidly detach the fixing nut 34, thereby detaching the axial flow product to be measured from the main shaft 3. The design of the quick assembly disassembly makes the whole measuring process more efficient and the assembly and disassembly are convenient.
The height gauge assembly 4 of the present utility model may be used with a conventional height gauge or with a custom height gauge as described below. More specifically, the customized height rule is mainly modified in that a distance adjusting structure 46 for adjusting the extending length of the measuring claw 43 is arranged between the measuring claw 43 and the main scale 42. As shown in fig. 1 and 2, the distance adjusting structure 46 of the axial flow product outer diameter measuring device has unique design and high practicability. Specifically, the distance adjustment structure 46 includes a telescopic slider to which the measuring pawl 43 is fixed, and a locking structure provided thereon. This design allows the measuring jaw 43 to horizontally telescope with the telescoping slide, thereby flexibly adjusting the length of extension of the measuring jaw 43. The characteristic makes it more convenient to measure axial flow products with larger sizes. In conventional measurement methods, the primary scale 42 may block the blades of the axial flow product, thereby making the measurement difficult or inaccurate. However, with such distance adjustment structure 46, the position of the measuring jaws 43 can be adjusted as desired, ensuring that they are able to accurately contact the outer diameter of the axial flow product without interference from the primary scale 42. This design thus significantly improves the applicability of the measuring device. The device is flexible to accommodate and provides accurate measurements, whether in the face of small or large axial flow products.
