Abstract
The invention discloses a vibration ageing device for movable loader arms, and relates to the technical field of machining equipment manufacturing. The device comprises a vibration exciter and a fixture body, wherein the fixture body consists of a top plate, two clamping plates which are welded below the top plate and parallelly arranged, and a plurality of pressing screws which penetrate through one clamping plate; two ear plates which stretch out of the side are arranged at the lower end of the vibration exciter; the two ear plates of the vibration exciter are fixed on the top plate of the fixture body through a pressing plate and a bolt which penetrates through the pressing plate; and reinforcing rib plates are welded between the top plate and the clamping plates of the fixture body. Compared with the prior art, the device has the advantages that the welding residual stress of the movable loader arms can be quickly and effectively eliminated, and the machining accuracy and dimensional accuracy and stability of the movable loader arms are improved; when 100 movable loader arms which are subjected to vibration ageing treatment by the vibration ageing device for the movable loader arms are detected, the residual stress is averagely reduced by 45 percent; and when the movable arms are subjected to tracking detection for three months after being loaded and used, weld joints are not cracked or damaged.
Description
Technical field
The present invention relates to machining equipment manufacturing technology field, especially a kind of for loading arm being carried out to the device of oscillating aging processing.
Background technology
Some this class A of geometric unitA of large-scale welding assembly, especially loading arm, in the damage survey statistics of its member, weld seam breaks and distortion is its major defect, and its reason is mostly because the welding residual stress producing after welding processing causes.For eliminating welding residual stress institute employing method, conventionally there are natural aging, Heat artificially ageing treatment and oscillating aging to process three kinds of methods at present, Heat artificially ageing treatment needs corresponding large-scale heat treatment furnace for large-scale welding assembly, due to the restriction of the conditions such as equipment, place and consider generally will not adopt from process costs; The long occupied fund of natural ageing cycle is large, is also not suitable for the needs of scale operation.Therefore the method that, the huge welding assembly of this body is eliminated welding residual stress still adopts oscillating aging treatment process as best one can.Oscillating aging treatment process requires the workpiece of processing to be combined with vibrator under a reliable and stable vibration environment of formation, and chooses suitable exciting point and vibrational frequency is carried out oscillating aging.In existing Vibration Aging Process, also do not have a kind of processing unit and method to go for mainly the member with thick plates, as loading arm carries out the device of oscillating aging.Main bearing member when this loading arm is shovel loader operation is the core component of whole equipment part; Wherein having a kind of loading arm is mainly to consist of with the tubular cross bearer welding that is connected these two blocks of swing arm plates two blocks of swing arm plates, is also welded with two otic placode is installed on tubular cross bearer.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly carries out in oscillating aging treatment process thick plates member, can effectively eliminate the loading arm vibration ageing device of loading arm welding residual stress.
The technical scheme that technical solution problem of the present invention adopts is: this loading arm vibration ageing device includes vibrator, there is one by top board and be welded on two clamping plate that be arranged in parallel below this top board and be installed on the clamp body that many clamping screws in described clamping plate wherein form, there are two otic placodes that stretch out to side described vibrator lower end, and two otic placodes of this vibrator are respectively by pressing plate with through on the top board that is bolted to described clamp body of this pressing plate.
In above-mentioned loading arm vibration ageing device technical scheme, technical scheme can also be more specifically: between the top board of described clamp body and its clamping plate, be welded with reinforcement gusset.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect: 1, can effectively to loading arm, carry out oscillating aging processing, improve the working accuracy of loading arm and the stability of dimensional precision; 2,100 loading arms that use loading arm vibration ageing device to carry out oscillating aging are detected, unrelieved stress on average declines 45%; Installation was followed the tracks of and is detected through 3 months after using, and the phenomenon of cracking destruction does not appear in commissure.

Fig. 1 is the schematic diagram of the embodiment of the present invention.
Fig. 2 is that the K of Fig. 1 is to view.
Fig. 3 is the left view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
ZL50 type loading arm vibration ageing device as shown in Figure 1, Figure 2, Figure 3 shows includes one by top board and is welded on two clamping plate that be arranged in parallel below this top board and is installed on the clamp body 1 that two clamping screws 5 in clamping plate wherein form, there are two otic placodes that stretch out to side vibrator 2 lower ends, and two otic placodes of this vibrator 2 are fixed on the top board of clamp body 1 by pressing plate 4 with through the bolt 3 of this pressing plate 4 respectively; Between the top board of clamp body 1 and its clamping plate, be welded with reinforcement gusset.ZL50 type loading arm is to consist of two blocks of swing arm plates 6 and tubular cross bearer 7 welding that are welded on two swing arm plate 6 middle parts, and its length is 2900 millimeters, and width is 1180 millimeters, and the thickness of swing arm plate is 50 millimeters.Two plywood sleeves that be arranged in parallel of vibration ageing device clamp body 1 are contained in apart from loading arm wherein in the scope of swing arm plate 6 termination 190-210 millimeters; By the many clamping screws 5 that are installed in clamping plate wherein, be rigidly connected with swing arm plate 6, by oscillation pickup 8 be arranged on be installed in vibrator 2 diagonal angles on clamp body 1 top board in the scope of another piece swing arm plate 6 termination 90-110 millimeters of loading arm; By pad dress thickness between two blocks of swing arm plates 6 of described loading arm and upholder, it is the rubber pad 9 of 80-100 millimeter; Each rubber pad 9 is 644 millimeters with the distance of swing arm plate 6 terminations, place.100 loading arms that use loading arm vibration ageing device to carry out oscillating aging are detected, and unrelieved stress on average declines 45%; Installation was followed the tracks of and is detected through 3 months after using, and the phenomenon of cracking destruction does not appear in commissure.
