A support seat is arranged below the working bench, a second worm which can rotate on the support seat is arranged inside the support seat, and the support seat is further provided with a first worm. The second worm and the first worm are meshed with each other. A worm gear is further arranged below the working bench, and the worm gear is meshed with the second worm. Inner threads are arranged on the worm gear, and the inner threads of the worm gear and the support screw rod are matched with each other. The transmission mode of a worm and a gear is used, the space height of an exciter (1) can be adjusted through a lifting device on the base (5) according to demands, the mounting and arranging work of the exciter (1) can be completed quickly, the accuracy of testing can be improved, structure is simple, and operating is convenient.
Description
Technical field
The utility model belongs to vibration exciter vibration test equipment field, relates in particular to a kind of vibration exciter mounting base.
Background technique
In the car load NVH development phase, need to obtain the vibrational structure characteristic of system, the structural vibration test needs to gather a large amount of test datas.The modal test of minor structure is generally finished by hammering method, and the modal test of macrostructure is difficult to encourage with hammering method, needs to adopt the vibration exciter of macro-energy.The vibration exciter outside dimensions is large, does not have the power hammer so convenient in the use, and it is harsher to the requirement of working space, installs fixing all cumbersome.Need firmly to contact with treating examining system or parts during vibration exciter work, and have a certain degree by test request, this just makes the installation of vibration exciter and is fixed on height and the angle certain requirement.When both angulations were smaller, fixing bolt that can adjusting vibration exciter itself was achieved, and slightly bigger angle then is difficult to realize, and vibration exciter itself can not realize that the displacement on the height regulates.Simultaneously since during vibration exciter work self vibration larger, need fixing reliable.
The model utility content
Can't regulate and fix insecure defective for the vibration exciter short transverse, technical problem to be solved in the utility model provides a kind of vibration exciter mounting base that satisfies needs in the different operating space.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of vibration exciter mounting base, comprise worktable and base, and described base is provided with support screw; Described worktable below is provided with bearing, is provided with the second worm screw that can rotate at bearing in the described bearing, also is provided with the first worm screw on the described bearing; Described the second worm screw is meshed with the first worm screw; Described worktable below also is provided with worm gear, and described worm gear is meshed with the second worm screw; Described worm gear is provided with internal thread, and the internal thread of described worm gear matches with support screw.
Described bearing has two, and described the first worm screw is installed on two described bearings; Described the second worm screw has two, is installed in respectively on two described bearings.
Described support screw has four, is distributed on four angles of described base.
Described worm gear has four.
Described the first worm screw end is provided with nut.
The utility model has the advantage of, this device adopts the kind of drive of worm and gear, only needs the nut on rotation the first worm screw, just can realize that worktable is along four steady liftings of support screw.The spatial altitude of vibration exciter can be adjusted as required by the lift device on the base, finish rapidly the mounting arrangements work of vibration exciter, and it the precision of test can be improved.Simple in structure, easy to operate.
Description of drawings
Fig. 1 is the structural representation of a kind of vibration exciter mounting base of the utility model;
Fig. 2 is the structural representation of Fig. 1 vibration exciter mounting base;
Mark among the above-mentioned figure is: 1, vibration exciter, 2, support screw, 3, worktable, 4, worm gear, 5, base, the 6, first worm screw, the 7, second worm screw, 8, bearing.
Embodiment
Fig. 1 and Fig. 2 are the structural representation of a kind of vibration exciter mounting base of the utility model, comprise worktable 3 and base 5, and base 5 is provided with support screw 2; Worktable 3 belows are provided with bearing 8, are provided with in the bearing 8 the second worm screw 7 of bearing 8 rotations, also to be provided with the first worm screw 6 on the bearing 8; The second worm screw 7 is meshed with the first worm screw 6; Worktable 3 belows also are provided with worm gear 4, and worm gear 4 is meshed with the second worm screw 7; Worm gear 4 is provided with internal thread, and the internal thread of worm gear 4 matches with support screw 2.
Bearing 8 has two, and the first worm screw 6 is installed on two bearings 8; The second worm screw 7 has two, is installed in respectively on two bearings 8.Support screw 2 has four, is distributed on four angles of base 5.Worm gear 4 has four.The first worm screw 6 ends are provided with nut.
This device adopts the kind of drive of worm and gear, only needs the nut on rotation the first worm screw 6, just can realize that worktable 3 is along the 2 steady liftings of four support screws.Support screw 2 cooperates with the screwed worm gear 4 of inner circle, and worm gear 4 rotates thereon provides lifting force, and can play the effect of nature locking, need not to add independent keying structure again.Lift device is fixed on the worktable 3, with its together lifting, has simplified drive mechanism.
During use, at first vibration exciter 1 is installed in above the worktable 3, then rotate the nut on the first worm screw 6, rotation by the first worm screw 6 is given the second worm screw 7 transmission of power, rotation by the second worm screw 7 to worm gear 4, has the screw thread that cooperates with support screw 2 to transmission of power on worm gear 4 inner circles again, self moves up and down along support screw 2 by rotarily driving of worm gear 4, on worktable 3 whole Action of Gravity Field worm gears 4, finally under the effect of worm gear 4, move up and down with worktable 3.
After adopting such structure, the spatial altitude of vibration exciter 1 can be adjusted as required by the lift device on the base 5, finish rapidly the mounting arrangements work of vibration exciter 1, and it the precision of test can be improved.Simple in structure, easy to operate.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or without improving design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
