Compared with the prior art, the invention can perform vibration aging treatment of a loader front frame with low noise and high efficiency, and the vibration exciter is not easy to damage.
Description
Technical field
The present invention relates to machining equipment manufacturing technology field, especially a kind of device for the front frame of shovel loader being carried out the oscillating aging processing.
Background technology
Main bearing member when front frame for loader is the shovel loader operation is the core component of whole equipment part; Front frame for loader is the box-shaped structural member that is made of Plate Welding, and its weld is many, complex structure.In the damage survey statistics to this front frame for loader, the crackle that the commissure of front frame produces is more, and its reason mainly is because front frame for loader causes at the welding residual stress that welding produces afterwards; Unrelieved stress also all has a significant impact dimensional precision stability and the supporting capacity of front frame for loader, needs to eliminate.The best way that front frame for loader is eliminated unrelieved stress is to adopt oscillating aging.Traditionally the oscillating aging of front frame for loader being processed is that single-piece is independently carried out; This method is that rubber pad is supported between front frame and the ground, vibrator and oscillation pickup is fixed on the front frame again, then seeks the resonance peak of front frame for loader and it is carried out the subresonance vibration.With this traditional oscillation time-effect method front frame for loader is processed, there are the following problems in actual production: 1, since the natural frequency of front frame for loader greater than 100 hertz, in the oscillating aging process, the vibrating noise of generation surpasses 85 decibels, has had a strong impact on Working environment; 2, because the natural frequency of front frame for loader is high, vibrator will be worked being higher than between 6000 rev/mins high velocity, and vibrator damages easily, and the oscillating aging equipment failure is many; 3, single-piece is carried out the oscillating aging processing to front frame, all will install and fix vibrator and oscillation pickup at every turn, and the operating time is long, and labour intensity is large, and work efficiency is low.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of front frame for loader vibration ageing device, and this front frame for loader vibration ageing device can solve existing front frame for loader oscillating aging and process the problem that noise is large, vibrator damages easily and work efficiency is low.
The technical scheme that technical solution problem of the present invention adopts is: this front frame for loader vibration ageing device includes vibrator and oscillation pickup, a platform is arranged, table top at described platform is provided with a plurality of through holes, be equipped with the polylith pressing plate on the described table top, in a plurality of described through holes, be coated with the bolt that is connected with described pressing plate; Described vibrator is fixed on the table top of described platform one end, and described oscillation pickup is placed on the table top of the described platform the other end.
In the above-mentioned front frame for loader vibration ageing device technical scheme, technical scheme can also be more specifically: each the described through hole end in described platform bottom is equipped with the nut that is communicated with through hole.
Further, be equipped with the polylith cushion block on the described table top.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect: 1, be rigidly fixed on the table top of platform when front frame for loader, front frame for loader and platform have just consisted of another beam type workpiece, the low frequency natural frequency of this beam type workpiece in the oscillating aging process, is to use the low-frequency resonance peak to carry out oscillating aging to process less than 70 hertz, therefore, the vibrating noise that produces is lower than the operating noise in workshop less than 75 decibels, does not affect Working environment; 2, because the natural frequency of the beam type workpiece that front frame for loader and platform consist of is low, vibrator is to work being lower than between 4500 rev/mins low regime, and vibrator is not easy damage, and the oscillating aging equipment failure is few; 3, vibrator and the oscillation pickup on the front frame for loader vibration ageing device platform table top only needs clamping once, just can carry out oscillating aging to many front frame for loaders simultaneously and process, and reduced the operating time, improved work efficiency.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the vertical view of Fig. 1.
Number in the figure explanation: platform 1, oscillation pickup 2, pressing plate 3, bolt 4, cushion block 5, rubber pad 6, vibrator 7, front frame for loader 8.
Embodiment
The invention will be further described below in conjunction with accompanying drawing embodiment:
Front frame for loader vibration ageing device as depicted in figs. 1 and 2 includes vibrator 7 and oscillation pickup 2, and a platform 1 is arranged, and platform is that length is 4000 millimeters, and width is 800 millimeters, and thickness is 100 millimeters steel plate; Table top at platform 1 is distributed with three rows, and it is 38 millimeters hole that every row has nine diameters that are evenly distributed; Each through hole end in platform 1 bottom all is welded with the nut that screw is communicated with through hole, and the nut of present embodiment is M36; Be placed with eight block pressur plates 3 and eight cushion blocks 5 on platform 1 table top of present embodiment, in eight through holes, be coated with respectively the bolt 4 that is connected with pressing plate 3; Vibrator 7 by two bent clamps be rigidly fixed in an end on platform 1 table top near a side edge, oscillation pickup 2 is placed on the place, nearly angle on the platform relative with vibrator 1 the other end table top.
Be rigidly fixed in when front frame for loader 8 on the table top of platform 1, front frame for loader 8 has just consisted of another beam type workpiece with platform 1, the low frequency natural frequency of this beam type workpiece is 65 hertz, in the oscillating aging process, be to use this low-frequency resonance peak to carry out oscillating aging to process, therefore, the vibrating noise of generation is less than 75 decibels, be lower than the operating noise in workshop, do not affect Working environment; Because the natural frequency of the beam type workpiece that front frame for loader and platform consist of is low, vibrator is to work being lower than between 4500 rev/mins low regime, and vibrator is not easy damage, and the oscillating aging equipment failure is few; Vibrator and oscillation pickup on the front frame for loader vibration ageing device platform table top only need clamping once, just can carry out oscillating aging to many front frame for loaders simultaneously and process, and have reduced the operating time, have improved work efficiency.
