Description
Technical field
The utility model relates to the fan vibration technical field of measurement and test, requires to relate to a kind of support that is used for fitting key phase sensor.
Background technology
In the fan vibration test, obtain the key that stable and accurate key signal is transient equilibrium work.What be used for fitting key phase sensor generally is that Magnetic gauge stand adds a universal bar or snakelike bar, and magnetic support is adsorbed on the bearing seat, and the cursor in the rotating shaft of key phase sensor alignment is measured.Because this structure of instability of universal bar more is applicable to than the measurement under the quiet environment; When blower fan generation abnormal vibrations need be handled; Fixedly the vibration of bearings of magnetic support is very big; The phenomenon that often magnetic support and universal bar are shifted or come off in the generation measuring process puts to no little inconvenience to vibration survey.If existing magnetic support directly is placed on the less bearing seat platen of vibration, again because of relatively poor can not do oversize of universal bar rigidity, the split measuring height that key is popped one's head in mutually and often do not reached rotating shaft.
Summary of the invention
The purpose of the utility model is exactly in order to solve magnetic support and universal bar displacement or the phenomenon that comes off in the measuring process that prior art exists, to put to no little inconvenience to vibration survey, and pop one's head in the mutually problem of the split measuring height that often do not reach rotating shaft of relatively poor oversize, the key that can not do of universal bar rigidity; A kind of support that is used for fitting key phase sensor is provided; The utility model is simple in structure; Use reliable; Install easy to carry; Existing rigidity preferably can be under the bigger test environment of vibration hold key phase sensor stable, adjusting key phase sensor height reaches the height and position of rotating shaft split easily again, can be placed on the key signal of realizing rotating shaft on the bearing seat platen and measure.
To achieve these goals, the utility model adopts following technical scheme:
A kind of support that is used for fitting key phase sensor comprises powerful Magnetic gauge stand, support bar I; Coupling sleeve; Support bar II, powerful Magnetic gauge stand, support bar I, coupling sleeve, support bar II connect successively, and the top on the support bar II is provided with the sliding sleeve assembly; Sliding sleeve assembly and key sensor connection mutually
Powerful Magnetic gauge stand, support bar I, coupling sleeve, support bar II connect through threaded engagement successively.
The sleeve outer wall of sliding sleeve assembly is provided with threaded hole, support bar II through clamping screw and threaded hole matching and fixing on the sliding sleeve assembly.
Sleeve can up-down adjustment in the position of support bar.
The sliding sleeve assembly is provided with fixed head, and fixed head is provided with the mounting hole of key phase sensor, and key phase sensor is connected with fixed head through the nut at two ends.
Principle of work: the powerful Magnetic gauge stand of the utility model, support bar I, coupling sleeve; Support bar II connects through threaded engagement successively; Top on the support bar II is provided with the sliding sleeve assembly, sliding sleeve assembly and key sensor connection mutually, and the sleeve outer wall of sliding sleeve assembly is provided with threaded hole; On the sliding sleeve assembly, sleeve can slide up and down at support bar support bar II through clamping screw and threaded hole matching and fixing.Through sliding up and down after adjustment sleeve position makes key phase sensor reach suitable measuring height, tighten clamping screw before measuring, make key phase sensor keep stable measuring height position, measure then, can guarantee the precision of measurement structure.
The beneficial effect of the utility model: the utility model can be stablized by hold key phase sensor under the bigger test environment of vibration; Solved in the test of power plant fan vibration and cause the key signal problem of unstable greatly because of vibrating, adjusting key phase sensor height reaches the height and position of rotating shaft split easily.
