Description
Technical field
The utility model relates to twin shaft hanging vibration table, needing to be particularly useful for the experiment and the research of adjustable parameter vibration source.
Background technology
Vibration table has the product of seriations such as electromagnetic type and horse race formula at present, has satisfied the needs of product detection with the part experimental study.The electromagnetic type vibratory equipment produces magnetic field with solenoid, thus by the size of regulating electric current reach regulate magnetic pole stressed size influence amplitude, and finish adjusting by the cycle of adjusting electric current to vibration frequency; The measure of regulating direction of vibration is that equipment is finished with the angle of inclination of stepless adjustment Vib., and the load mounting platform is a plane formula, and equipment is that the seat formula is installed placement, this type equipment precision height, easy to adjust, of many uses.The shaking table of horse race formula is to produce vibration and carry out vibration isolation with spring with the motor drives eccentric structure, and the adjustability of this kind equipment is relatively poor, is mainly used in the simulation of vehicle etc.
The plane formula mounting platform is a kind of omnipotent structure, it gives the user installing space with maximum, but also make the installation stilt that does not carry out testing become the important component part of mass of vibration simultaneously, especially during the adjusting on carrying out direction of vibration, the design difficulty, the processing charges that support are installed are also had significantly and rise.It is little that the seat formula of equipment is laid the size that takes up room, but its top person's of being to use operating space often need be improved the experiment that following junk is arranged support is installed.In many experimental studies, the difference in high-precision vibration mode and the commercial Application is bigger, makes the also corresponding increase of deviation between test findings and application.
Summary of the invention
Technical matters: the purpose of this utility model provides a kind of amplitude, frequency and direction of vibration and all can adjust, and has the box load carrying platform that is suspended, and the twin shaft hanging vibration table of orthoscopic vibration can be provided.
Technical scheme: the utility model twin shaft hanging vibration table, it by the frame of carrying vibrational energy, be located at vibration isolator on the frame, the box load carrying platform of the suspension that tested article are installed, the symmetry that link to each other with vibration isolator are installed in the vibrator that also can adjust setting angle on the box load carrying platform, the motor that is connected with vibrator by transmission shaft, the variable frequency power source of driving motor (3) are formed, motor is located on the rotatable rocking bar, is provided with connector between frame and the rocking bar.
The utility model twin shaft hanging vibration table, described vibration isolator is made of the wire rope and the rope wedge of isolation spring, fine tuning function of height adjusting lever, coarse height; Described vibrator is made of the main eccentric block and the secondary eccentric block of eccentric gross mass of two interchangeable and adjustment eccentric angle; Described frame is made of side plate frame, upper frame, rotation axis and lock slots.
Technique effect: the utility model twin shaft hanging vibration table, make vibrator centroid position on the box load carrying platform reach the same height of pivot center of rocking bar substantially by the initial adjustment length of steel wire rope, after tested article have been installed, the center of gravity of box load carrying platform can produce and move down, and with adjusting lever the vibrator centroid position is adjusted back to the height of rocking bar pivot center then; Can change vibration frequency by the frequency of adjusting motor power.After vibration frequency changed, changing amplitude as needs can be with the angular setting of the main relatively eccentric block of secondary eccentric block in the vibrator.By the barycenter of box load carrying platform, the barycenter of the measured object of installation is as overlapping with the platform barycenter when design for the twin shaft exciting force, and vibration mode is a straight line, as the not overlapping elliptic motion that produces different major and minor axis ratios.Adjusting direction of vibration should adjust the angle of vibrator and rocking bar simultaneously.This testing table needing not only to can be used for the experiment and the research of vibration source, the experiment that experiment that following junk is arranged and liquid are overflowed also has favorable applicability, the box load carrying platform high characteristics of installation effectiveness of having living space, can in 0 °～90 ° even 0 °～180 ° angular ranges, adjust direction of vibration, its compact conformation, operation, adjustment, easy to maintenance, cost is low, has practicality widely.

Embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
The utility model twin shaft hanging vibration table mainly is made up of frame 1, vibration isolator 14, box load carrying platform 9, vibrator 7, transmission shaft 6, motor 3, rocking bar 5, connector 19 and variable frequency power source 8.Frame 1 is made up of side plate frame 4, upper frame 15, rotation axis 18 and lock slots 2, and vibration isolator 14 is made up of isolation spring 13, adjusting lever 12, wire rope 11 and rope wedge 10, and vibrator is made up of main eccentric block 16 and secondary eccentric block 17.The left and right sides grillage 4 of frame 1 is located on ground, upper frame 15 is installed in the top of side plate frame 4, vibration isolator 14 is installed on upper frame 15, isolation spring 13 is located at vibration isolator 14 and upper end, adjusting lever 12 is located at the centre of isolation spring 13, the height that is used for the box load carrying platform 9 of fine control, the lower end connection cord wedge 10 of adjusting lever 12, adjust the length of wire rope 11 with rope wedge 10, the height of center of mass that makes box load carrying platform 9 height with the rotation axis 18 of frame 1 basically is identical, the lower end of wire rope 11 connects a rope wedge 10 again, and this rope wedge 10 is connected with box load carrying platform 9.Vibrator 7 is installed on the box load carrying platform 9, two groups of master's eccentric blocks 16 and secondary eccentric block 17 are equipped with in its inside, the main relatively inclined to one side piece 16 of secondary eccentric block 17 can be with arbitrarily angled fixing so that the exciting force of different values to be provided, or adjust amplitude in the mode of adjusting relative angle, also can adopt the mode of adjusting the eccentric block centroid position.Vibrator 7 can arbitrarily angledly be fixed on box load carrying platform 9, is the important component part of adjusting direction of vibration.Motor 3 joins by transmission shaft 6 and vibrator 7 and the motion moment of torsion is provided, and motor 3 provides energy by variable frequency power source 8, can adjust vibration frequency when changing the frequency of power supply.Rocking bar 5 is bases of motor 3, and an end of rocking bar 5 is installed on the rotation axis 18 of frame 1, because the insufficient rigidity of rocking bar 5 to bear two power that motor was spread out of, uses connector 19 that rocking bar 5 is fixing with frame 1.
