Abstract
The utility model provides an angle gauge for vane measurement, which consists of an angle device, an indicator pointer, a gauge handle, a fixed catch plate and a movable catch plate, wherein the angle device is fixed on the gauge handle, the middle part of the indicator pointer is riveted at the circle center of the angle device, a heavy member is connected at the lower part of the indicator pointer, the indicator pointer is kept perpendicular to the horizontal plane all the time during the measurement, the fixed catch plate is fixed at the foremost end of the gauge handle, the movable catch plate is sleeved at the rearmost end of the gauge handle in a way of moving forward and backward along the gauge handle, a locking nut is arranged on the movable catch plate, and V-shaped groove structures are formed on the inner walls of the fixed catch plate and the movable catch plate. The angle gauge is adopted to rapidly and accurately read the installation angle value from the angle device directly, simplifies the measurement operation without the calculation procedure, and achieves the effect of installation and measurement at the same time.
Description
Technical field
The utility model relates to the angle installation of air-cooled fan blade and the specific purpose tool of measurement of angle, and the use of blade angle chi can be simplified blader's preface, is the specific purpose tool that improves air cooling blower fan impeller installation effectiveness and accurately measure the blade angle degree.
Background technology
The air-cooled fan blade profile is a streamline distortion airfoil type (Fig. 1), profile is irregular, and blading is in air duct inside, the blade angle degree is meant fractal line and the horizontal angle on the blade tip cross section, can't directly measure its setting angle value with general tool, just can draw angle value through calculating again after having only measurement, need to calculate time-consuming bothersome during installation while measuring, installation difficulty and time have been increased greatly, installation reliability is not strong, needs repeatedly dismounting to proofread and correct, and meeting is not had a strong impact on the blower fan running as setting angle.
Summary of the invention
The utility model blade chi that takes measurement of an angle, its purpose are to provide a kind of blade of the simplified blader preface that can address the above problem chi that takes measurement of an angle.
The utility model blade chi that takes measurement of an angle, its by: protractor, pointer, chi handle, fixing chuck plate, movable clamp are formed, protractor is fixed on the chi handle, and the pointer middle part is riveted on the protractor round dot, and weight is arranged at the bottom, pointer remains horizontal vertical during measurement, fixing chuck plate is fixed in the chi handle foremost, and the active card sleeve-board can move forward and backward along the chi handle in the rear portion of chi handle, on the movable clamp set nut is arranged, fixing chuck plate and movable clamp inwall are the V-shaped groove structure.
The utility model beneficial effect is: use the utility model directly can read the setting angle value fast accurately from protractor, measuring operation is very convenient, saves calculation procedure, but measures while installing.
Description of drawings
Fig. 1 is a fan blade.
Fig. 2 the utility model blade chi synoptic diagram that takes measurement of an angle.
1 is fixing chuck plate among the figure, and 2 is protractor, and 3 is pointer, and 4 is fixing chuck plate, and 5 is movable clamp, and 6 is set nut, and 7 for needing the measurement blade, and α is a setting angle.
Embodiment
The utility model blade chi that takes measurement of an angle, its by: form by protractor, pointer, chi handle, fixing chuck plate, movable clamp, protractor is fixed on the chi handle, and the pointer middle part is riveted on the protractor round dot, and the bottom has weight to fix, pointer remains horizontal vertical during measurement, fixing chuck plate is fixed in the chi handle foremost, and the active card sleeve-board can move forward and backward along the chi handle in the rear portion of chi handle, on the movable clamp set nut is arranged, fixing chuck plate and movable clamp are the V-shaped groove structure.
Below in conjunction with Fig. 2 the utility model is described:
Only need during measurement to be positioned over V-shaped groove on fixing chuck plate and the movable clamp respectively on the blade front and rear edges, at this moment V-shaped groove summit line is just in time on the fractal line in blade tip cross section on two clamps, and the value of pointer indication is the blade angle degree on the protractor.As the established angle that requires blade among Fig. 2 is 10 °, and promptly fractal line in blade tip cross section and horizontal angle are 10 °, and when blade was installed, when blade took measurement of an angle the chi pointer indicated value is 10 ° on protractor, then the blade installation site was correct.The special-purpose blade angle chi scope of taking measurement of an angle is 0 °～90 °, and movable clamp is removable on the chi handle, though can measure the blade of the multiple size that varies in size, each angle of section on the blade also can be measured for same blade.
Claims (3)
1, the blade chi that takes measurement of an angle, its by: protractor, pointer, chi handle, fixing chuck plate, movable clamp are formed, it is characterized in that: protractor is fixed on the chi handle, the pointer middle part is riveted on the protractor round dot, weight is arranged at the bottom, fixing chuck plate is fixed in the chi handle foremost, and the active card sleeve-board can move forward and backward along the chi handle in the rear portion of chi handle.
2, the blade according to claim 1 chi that takes measurement of an angle is characterized in that: on the movable clamp set nut is arranged.
3, the blade according to claim 1 chi that takes measurement of an angle, it is characterized in that: fixing chuck plate and movable clamp inwall are the V-shaped groove structure.
