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 being used for carried out the device that oscillating aging is handled to loading arm.
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 mostly is because the welding residual stress that produces after the welding processing causes.Being used to eliminate welding residual stress institute employing method at present has seasoning, artificial heating ageing treatment and oscillating aging to handle three kinds of methods usually; Artificial heating ageing treatment needs corresponding large-scale heat treatment furnace for large-scale welding assembly, consider generally will not adopt owing to the restriction of conditions such as equipment, place and from the technology cost; The seasoning cycle, long occupied fund was big, also was not suitable for the needs of scale operation.Therefore, the huge welding assembly of this body method of eliminating welding residual stress still adopts the oscillating aging treatment process as best one can.The requirement of oscillating aging treatment process need combine the workpiece of handling under reliable and stable vibration environment of formation with vibrator, and will choose suitable exciting point and vibrational frequency is carried out oscillating aging.In existing oscillating aging technology, also there are not a kind of processing unit and method to go for main member with thick plates, carry out the device of oscillating aging like loading arm.Main bearing member when this loading arm is the shovel loader operation is the core component of whole equipment part; It mainly is to be made up of with the tubular cross bearer welding that is connected these two blocks of swing arm plates two blocks of swing arm plates that a kind of loading arm is wherein arranged, and on tubular cross bearer, also is welded with two otic placode is installed.
?
Summary of the invention
The technical problem that the present invention will solve provides a kind ofly carries out in the oscillating aging treatment process the thick plates member, can eliminate the loading arm vibration ageing device of loading arm welding residual stress effectively.
The technical scheme that technical solution problem of the present invention is adopted is: this loading arm vibration ageing device includes vibrator; Have one by top board be welded on two clamping plate that laterally arrange below this top board and be installed on wherein the clamp body that many clamping screws in the said clamping plate constitute; There are two otic placodes that stretch out to the side said vibrator lower end, two otic placodes of this vibrator respectively through pressing plate with pass on the top board that is bolted to said clamp body of this pressing plate.
In the above-mentioned loading arm vibration ageing device technical scheme, technical scheme can also be more specifically: be welded with the reinforcement gusset between the top board of said clamp body and its clamping plate.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect: 1, can carry out oscillating aging to loading arm effectively and handle, improve the working accuracy of loading arm and the stability of dimensional precision; 2,100 loading arms that use the loading arm vibration ageing device to carry out oscillating aging are detected, unrelieved stress on average descends 45%; Followed the tracks of detection through 3 months after installation is used, the phenomenon of cracking destruction does not appear in the commissure.
