Abstract
The invention provides an improved device for measuring blade type line chord width, which adopts a standard measuring instrument, and has a simple structure, quick and convenient operation and high measuring accuracy. The device comprises a vernier caliper and is characterized by also comprising a base and a height vernier caliper, wherein an I-shaped blade positioning block is arranged on the base; the height vernier caliper is arranged on the base through a fixing piece; and the vernier caliper is arranged on the height vernier caliper through a connecting piece.
Description
(1) technical field
The present invention relates to the blade processing field of measuring technique, be specially a kind of device of measurement blade type line chord width of improvement.
(2) background technology
Along with the continuous development of blade design studies technology, more and more higher to the manufacturing accuracy requirement of blade, some traditional measurement method and equipment commonly used can not satisfy its accuracy requirement far away.Measurement for blade type line chord width, generally be with the marking pen marking of ruling on the height that the blade profile requirement detects, the string that hand-held then vernier caliper is measured molded lines in line place is wide, because blade profile is irregular, and there is error line in itself, measurement data cause this measuring method can't find the measuring position of preparation, so can not reflect accurate values fully; Also useful clamp is placed on the height of requirement and measures, though can avoid the error on the height, need to record light leak value between clamp and vane type line by hand, because there is the error in the manufacturing in clamp itself with clearance gauge, and also there is error in hand dipping, so also can't record exact value.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of device of measurement blade type line chord width of improvement, it adopts etalon, and is simple in structure, swift and convenient to operate, the measuring accuracy height.
Its technical scheme is such, it comprises vernier caliper, it is characterized in that: it also comprises base, vernier height gauge, I shape blade locating piece is installed on the described base, described vernier height gauge is installed on described base by fixture, and described vernier caliper is installed on described vernier height gauge by web member.
It is further characterized in that: guide plate is installed in described base both sides; Described I shape blade locating piece and guide plate gap, described both sides are slidingly matched.
The device of the measurement blade type line chord width of a kind of improvement of the present invention, it is simple in structure, measures convenient and swift reliably, and cost of manufacture is low, and the cycle is short, convenient enforcement.

Fig. 1 is the main TV structure synoptic diagram of device of the measurement blade type line chord width of a kind of improvement of the present invention;
Fig. 2 is the right TV structure synoptic diagram of Fig. 1;
Fig. 3 is the plan structure synoptic diagram of Fig. 1.
(5) embodiment
See Fig. 2, the present invention includes base 5, vernier height gauge 1 and vernier caliper 3, I shape blade locating piece 7 is installed on the base 5, vernier height gauge 1 is installed on base 5 by fixture 8, and vernier caliper 3 is installed on vernier height gauge 1 by web member 2.Guide plate 6 is installed in base 5 both sides; I shape blade locating piece 7 is slidingly matched with both sides guide plate 6 gaps.
Specifically describe the course of work of utilizing the present invention to measure blade type line chord width below: adjust vernier height gauge 1 with standard gauge, the vernier caliper 3 that is contained in vernier height gauge 1 is flushed with standard gauge, the reading of vernier height gauge 1 is set to 0, then blade 4 to be measured is positioned on apparatus of the present invention, blade 4 touch I shape blade locating piece 7, the molded lines of blade 4 is contacted with the fixedly card base of vernier caliper 3, determine direction of measurement, vernier height gauge 1 is transferred to the height that requires measurement, blade 4 touch I shape blade locating piece 7 and moves, blade 4 touch I shape blade locating piece and moves, make molded lines one side and vernier caliper 3 fixedly card base contact, it is wide to measure the molded lines strings with vernier caliper 3.Wherein, I shape blade locating piece 7 can its objective is and can adjust leaf position according to the blade size along both sides guide plate 6 move left and right, and it is wide to make device can measure the molded lines string of different big and small blades.
Claims (3)
