The vibration stress relief device comprises a vibration exciter and a vibration measurement device, and is characterized by being provided with a platform, wherein a table board of the platform is provided with a plurality of through holes, a plurality of pressing plates are arranged on the table board, and bolts which are connected with the pressing plates respectively penetrate through the through holes; and the vibration exciter is fixed on the table board on one end of the platform, and the vibration measurement device is arranged on the table board on the other end of the platform. Compared with the prior art, vibration stress relief can be high-efficiently carried out for the front wheel of the loader through the vibration stress relief device in low noise, and the vibration exciter is not easy to damage.
Description
Technical field
The utility model relates to machining equipment manufacturing technology field, especially a kind of device for the front frame of shovel loader being carried out oscillating aging and 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 is mainly 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 ground, then vibrator and oscillation pickup are fixed on front frame, 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, due to 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, the natural frequency due to front frame for loader is high, and vibrator will be worked between higher than the high velocity of 6000 rev/mins, and vibrator easily damages, and the oscillating aging equipment failure is many; 3, single-piece is carried out oscillating aging to front frame and is processed, and all will install vibrator and oscillation pickup fixingly at every turn, and the operating time is long, and labour intensity is large, and work efficiency is low.
The utility model content
The technical problems to be solved in the utility model is to provide 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 easily damages and work efficiency is low.
The technical scheme that the utility model technical solution problem adopts is: this front frame for loader vibration ageing device includes vibrator and oscillation pickup, a platform is arranged, be provided with a plurality of through holes on the table top of described platform, be equipped with the polylith pressing plate on described table top, be coated with the bolt that is connected with described pressing plate in a plurality of described through holes; 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 above-mentioned front frame for loader vibration ageing device technical scheme, technical scheme can also be more specifically: each the described through hole end bottom described platform is equipped with the nut that is communicated with through hole.
Further, be equipped with the polylith cushion block on described table top.
Owing to having adopted technique scheme, the utility model 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 is less than 70 hertz, in the oscillating aging process, to use the low-frequency resonance peak to carry out oscillating aging to process, therefore, the vibrating noise that produces is less than 75 decibels, lower than the operating noise in workshop, do not affect Working environment; The natural frequency of the beam type workpiece that 2, consists of due to front frame for loader and platform is low, and vibrator is to work between lower than the low regime of 4500 rev/mins, and vibrator is not easy to damage, and the oscillating aging equipment failure is few; 3, vibrator and the oscillation pickup on 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 utility model embodiment.
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 utility model is described in further detail 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 the steel plate of 100 millimeters; Be distributed with three rows on the table top of platform 1, it is the hole of 38 millimeters 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 the present embodiment is M36; Be placed with eight block pressur plates 3 and eight cushion blocks 5 on platform 1 table top of the present embodiment, be coated with respectively the bolt 4 that is connected with pressing plate 3 in eight through holes; Vibrator 7 is rigidly fixed in a close side edge of an end on platform 1 table top by two bent clamps, 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, lower than the operating noise in workshop, do not affect Working environment; The natural frequency of the beam type workpiece that consists of due to front frame for loader and platform is low, and vibrator is to work between lower than the low regime of 4500 rev/mins, and vibrator is not easy to damage, and the oscillating aging equipment failure is few; Vibrator and oscillation pickup on 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.
