Abstract
The utility model relates to an instrument for testing the life time of the screw clamping member of an electric fan, which comprises a rotary mechanism of the clamping element, a column elevating mechanism, a compacting cylinder and a control box. A worm gear case of the rotary mechanism of the clamping element drives the clamping element to continuously, obversely and reversely rotate through an extension rod and a clamping head. Thus, the instrument can replace the human hands to rapidly and correctly test the life time of the screw clamping element of the electric fan. The instrument has the advantages of simple drive system, compact structure, easy adjustment and visual display, and has practicability to enhance the quality of the electric fan.
Description
The utility model is a kind of electric fan spiral instrument in clamping element life-span of testing.
The life-span of spiral clamping element is an important quality index of electric fan.National standard " alternating current fan and speed regulator " is the regulation of the 2.11.7 bar in the literary composition (GBn158-82): the spiral clamping element in pitch angle and the arrangement for adjusting height, and must not be malfunctioning after clamping test 500 times.The longevity test of electric fan spiral clamping element adopts manual mode to realize before the utility model is made, promptly with the continuous forward and reverse rotating screw clamping element of hand to test its life-span.The shortcoming of manual mode is that the mechanical action of repetition makes people's fatigue easily, and number of revolutions easily makes mistakes by human brain memory, influences the accuracy of test data.
The purpose of this utility model provides a kind of continuous forward and reverse rotating screw clamping element of staff that can replace and tests the instrument in its life-span.
The concrete structure of the instrument that the utility model provides as shown in Figure 1.It comprises clamping element rotating mechanism, upright column elevator structure, clamping cylinder (5) and control box (1).The clamping element rotating mechanism is the action actuating mechanism of this instrument.It is made up of motor (13), worm gear case (12), extension bar (8), chuck (7), cam (10) and microswitch (9) (11).Extension bar (8) is fixedlyed connected with the worm gear in the worm gear case (12).Motor (13) drives extension bar (8) by the worm and wormwheel in the worm gear case (12).The chuck (7) that is fixed on extension bar (8) front end is used for rotating spiral clamping element (6) to be measured.Cam (10) also is housed in the middle of the extension bar (8), cam (10) rotates with extension bar, and when cam (10) touched the microswitch (11) of upper end, extension bar (8) was rotated in the forward, when cam (10) touched the microswitch (9) of lower end, extension bar (8) was done reverse rotation.The anglec of rotation of spiral clamping element (6) can be determined in the position of regulating 2 microswitches, to satisfy the actual needs that use.2 microswitches can be imported trigger pip digital display counter (4) simultaneously, thereby realize counting automatically.The upright column elevator structure is made up of handle (19), conical gear (18), screw rod (16), nut (17), column (14) and set nut (15) etc., its effect is a height of regulating column (14), makes the spiral clamping element of electric fan can snap in chuck (7).Turning handle (19) by conical gear (18) and screw rod (16), nut (17), can make column (14) move up and down.After adjustment finished, tightening set nut (15) can vertical columns (14).The effect of clamping cylinder (5) is that electric fan to be measured is fixed on the control box (1).In the control box (1) electrical equipment and pneumatic control components can be installed.
The instrument kinematic train that the utility model provides is simple, and compact conformation is easy to adjust, and has versatility.Use this instrument and can fast, correctly test the life-span of electric fan spiral clamping element.
It is following that 1 pair of concrete enforcement of the present utility model is described further with reference to accompanying drawing.Motor (13) orders about extension bar (8) through worm gear case (12) and slowly runs.Motor (13) is optional to be that 25 watts, moment are that 5 kilograms centimetres, rotating speed are 60 rev/mins micro-machine, the small-sized worm gear case with buffer protection function that worm gear case (12) can be selected ratio of gear i=30 for use with power.Just in case the spiral clamping element is malfunctioning, extension bar (8) can stop operating, and avoids damaging clamping element.Can determine the rotating speed of extension bar (8) according to the ratio of gear of the actual speed of motor and worm gear case, to satisfy the testing requirements of 10 motion cycle of per minute.Digital display counter (4) and digit preset dial (3) can be set on the control box panel (2), be used for showing test data respectively and preestablish testing time.
In addition, be installed on the column (14) if the rotating mechanism of instrument is turned over 90 degree, extension bar (8) is stretched out downwards, instrument also can be used for testing electric fan and shakes the head life-span of knob so.
Claims (2)
1, a kind of electric fan spiral instrument in clamping element life-span of testing is characterized in that it is made up of clamping element rotating mechanism, upright column elevator structure, clamping cylinder and control box.
2, instrument according to claim 1 is characterized in that described clamping element rotating mechanism is made up of motor, worm gear case, extension bar, chuck, cam and microswitch.
