Description
Technical field
The utility model relates to a kind of shake table, specifically is meant a kind of shake table of new type of adjustable joint magnetic gap.
Background technology
Common electromagnetic vibration generator system generally has two kinds of forms, and a kind of is to control oscillation intensity by regulation voltage, and another kind is to control oscillation intensity by regulating electric current.No matter adopt which kind of control mode, also having a critical problem is exactly magnetic gap.Appropriate magnetic gap just can make vibration produce best effect.
For common shake table, the elastic force of shake table compression spring is adjusted in advance with a certain weight radix, but because vibrating object weight is not wait, cause the gap (being commonly called as magnetic gap) between shake table tractive magnet and embedding iron that variation has taken place, variation has taken place in magnetic gap, amplitude is corresponding to change, and variation has also just taken place the natural vibration effect.For example, be that radix is adjusted to correct position with magnetic gap with 100kg, the workpiece effect of at this moment vibrating about 100kg is fine, shows as the big and vibration of amplitude steadily; But same situation is when becoming the 200kg left and right sides to workpiece, and effect is just bad.Trace it to its cause, workpiece weight is double, lifts spring continuation compression and realizes new dynamic balance needs, embedding iron is also and then taken advantage of a situation and is moved down, and magnetic gap is littler much than the original correct position of adjusting, and the magnetic gap variable force will limit amplitude, even magnetic takes place hit, so vibrating effect variation.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, this novel vibrating platform, mainly by vibration pedestal band guide rail 1, and the electromagnet directive slide track 2 that is connected in vibration pedestal guide rail 1 inboard is formed, described electromagnet directive slide track 2 is provided with tractive magnet 3, guide holder 4 outside vibration pedestal guide rail 1 and electromagnetism directive slide track 2 corresponding arranged outside have, this shake table also comprises backboard 5, position corresponding with tractive magnet 3 below described backboard 5 is provided with embedding iron 6, described backboard 5 is by lifting spring 7 and guiding, preloading adjusting rod 8 connects, and forms magnetic gap 9 between described tractive magnet 3 and embedding iron 6.Appropriate magnetic gap 9 just can make vibration produce best effect.
Can both obtain good jolt ramming in order to realize that multiple Different Weight specification product vibrates on same shake table, this shake table also includes magnetic gap and adjusts structure 10, and described magnetic gap is adjusted structure 10 and is positioned at tractive magnet 3 tops; Described magnetic gap is adjusted structure 10 and is comprised adjusting support 11, base 13 and regulate screw mandrel 12, described adjusting screw mandrel 12 along continuous straight runs are connected in to be regulated on the support 11, described base 13 is " protruding " word structure, and described adjusting support 11 adopts the hinged eight-sided formation that forms of turning cylinder successively by seven isometric connecting rods and base 13 tops; Described base 13 tops and connecting rod are isometric.
Two connecting rod left sides locating vertical direction in the described adjusting support 11 are adjustment seat 14, and the right is right guide holder 15, is provided with screw thread on described adjusting screw mandrel 12, and one end and adjustment seat 14 adopt and be threaded, and other end axial location is on right guide holder 15; Described adjusting screw mandrel 12 employing pins 16 and back-up ring 17 axial location are on right guide holder 15, and described pin 16 is vertical with adjusting screw mandrel 12, and is distributed in right guide holder 15 both sides, and adopt pin 16 that back-up ring 17 and adjusting screw mandrel 12 is fixing; The end that described adjusting screw mandrel 12 is connected with right guide holder 15 extends vibration pedestal guide rail 1 outside and forms handle 18.This magnetic gap guiding mechanism 10 is by screw mandrel motion adjustment magnetic gap 9.Lifting spring 7 does not need to apply great pretightning force, and a needs can balance embedding iron 6 and backboard 5 gravity are just passable, and key is will the adjustment level.
Adjust structure 10 both sides at described vibration pedestal guide rail 1 inboard magnetic gap and also be respectively equipped with projection, below described tractive magnet 3, be provided with electromagnet stent, and between described electromagnet stent and projection, also be respectively equipped with extension spring 19; Described magnetic gap is adjusted structure 10 tops and is closely attached on the electromagnet stent lower surface.
We are called H with the distance between adjustment seat 14 and the right guide holder 15, and adjusting support 11 eight-sided formation tops are called L to the distance of bottom, as shown in Figure 1.The product of arbitrarily putting a weight specification such as 150kg, is lifted spring 7 because gravity embedding iron 6 and backboard 5 can move down further compression on backboard, produce the elastic force of corresponding size with the gravity complete equipilibrium until lifting spring 7.At this moment use magnetic gap guiding mechanism 10, allow electromagnet stent move down, up to the magnetic gap that need to obtain.Action output is as follows, if regulate screw mandrel 12 dextrorotation, adopt between screw axis and the adjustment seat 14 and be threaded, and be axial positioning structure between right guide holder and the adjusting screw mandrel 12, regulate support 11 left and right sides distance H and diminish this moment, it is big that L becomes, promptly regulating screw mandrel 12 drive adjustment seats 14 moves horizontally backward, regulating screw mandrel 12 simultaneously also drives right guide holder 15 and moves horizontally left, directive slide track 2 constraint tractive magnet supports keep level, promote tractive magnet by hinge and connecting rod and move up.Such result is that dextrorotation H diminishes, and it is big that L becomes, because the tractive magnet support moves up, magnetic gap reduces; On the contrary, 12 left-handed then H become big as the adjusting screw mandrel, and L diminishes, and the tractive magnet support moves down, and magnetic gap increases, and so cover guiding mechanism existence is arranged, and shake table just can adapt to the needs of various weight specification products vibrations.
As mentioned above, just can realize the utility model preferably.
