Angle is smaller, and the pedestal of vibration device is detachably connected on positioning plate, when the angle of positioning plate changes, vibration device
Tilt angle also occur to change accordingly, after the tilt angle of vibration device is set up, the pin on sliding block is inserted into positioning
On bar in corresponding location hole, all sliding blocks are fixed, carrier bar keeps stablizing.Interconnecting piece on vibration device is adjusted as production
After face on product wait connect is parallel, adjust the length of telescoping mechanism, until interconnecting piece offsets with product, then by interconnecting piece and
Product is connected and fixed.Due to can connect vibration device on each positioning plate, the vibration on muti-piece positioning plate can be filled
It sets while being connected on product, make multiple positions of product while vibrating.
Further, the telescoping mechanism includes fixed link, sliding bar and the bolt for locking, and fixed link is fixed on described
On pedestal, sliding bar is parallel with fixed link, and sliding bar is slidably connected in fixed link, is equipped with bar shaped in fixed link in the axial direction
First sliding groove, be equipped with the second sliding slot of bar shaped on sliding bar in the axial direction, the spiro rod section of bolt passes through first sliding groove and the
Two sliding slots.When loosering a bolt, sliding bar can slide on the length direction of fixed link, and then adjust the length of telescoping mechanism, adjust
After the length for determining telescoping mechanism, bolt is tightened, keeps fixed link and sliding bar relatively fixed.
Further, flanged joint between the pedestal and the positioning plate.Pedestal can be firmly attached by flanged joint
On positioning plate.
Further, the interconnecting piece includes connecting plate and sucker, and connecting plate is fixed on the telescopic end of the telescoping mechanism,
Sucker is fixed on connecting plate far from the side of telescoping mechanism.Product is connected using sucker suction.
Further, the vibration excitor is vibrating motor.Vibrating motor installation is simple, easy to use.
Further, further include submergence pond, submerge in pond and be loaded with lubricating oil, the locating rod, sliding block, pin and carrier bar are equal
It is immersed in lubricating oil.During vibration-testing, between the positioning plate and hinge of carrier bar, between sliding block and locating rod, it is sliding
Since vibration will rub between block and pin, the position that these rub can be moistened after being immersed in lubricating oil
It is sliding, reduce abrasion and extend the service life, while using the insulating effect of lubricating oil, reducing noise.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of shake table of the embodiment of the present invention.
Specific embodiment
Below by specific embodiment, the present invention is described in further detail:
