Description
Technical field
The utility model relates to a kind of frock that is used for packing engineering machinery, is specifically related to a kind of excavator boom assembly welding frock.
Background technology
The main execution unit of excavator forms by swing arm, dipper and scraper bowl are hinged, because the specific (special) requirements of local stress, swing arm and dipper all adopt the irregular box-shaped Welding Structure of asymmetric long-armed type, and this structure has caused very big difficulty to the each several part contraposition welding of swing arm, dipper.
Dipper mainly is made up of left and right side plate and upper plate, lower shoe, be provided with in front end, middle part and the rear end of left and right side plate respectively and be used for and excavator swing arm, four hinged hinge holes of scraper bowl, relative position between each hole and spacing all have dimension precision requirement, for the planform and the dimensional accuracy that guarantee dipper, its welding procedure is generally: 1. at first with dipper lower shoe and left and right sides plate contraposition, typing; 2. with above-mentioned each plate point postwelding, the dipper upper plate covered point is welded into box structure on the side plate; 3. integral solder.Owing between the biside plate certain position required precision is arranged, therefore, the whole contraposition of dipper, setting just seem very important, generally adopt special equipment to weld the contraposition machine during contraposition and carry out contraposition, to bit combination, the location clamps laggard spot welding typing and forms an integral body with each part of dipper.
In the prior art, welding contraposition machine adopts the large hydraulic tooling device usually, and it comprises hydraulic system, hold down gag, displacement system and workbench etc., and wherein hold down gag adopts electromagnet to hold biside plate and lower shoe location.Because hydraulic pressure tooling device complex structure, for the excavator of making small lot, prepattern production, cost of investment is too high, and need be to the hydraulic system periodic maintenance, the maintenance cost height, and when the change product type, the transformation of the way difficulty of hydraulic pressure frock is big, thereby causes the waste of cost of investment; On the other hand, owing to adopt welding lower shoe earlier, the welding manner of bonnet upper plate, therefore upper plate only carries out integral solder at outer surface and biside plate, can't weld internal weld seams, and find that in actual use the probability that the stressed cracking phenomena of upper plate takes place is much larger than lower shoe, therefore, the welding fastness of upper plate will directly influence product quality.
Summary of the invention
The utility model purpose provides a kind of simple in structure, excavator boom assembly welding frock that cost of investment is low, adopts this frock assembly welding dipper, helps to improve the quality of products.
For achieving the above object, the technical solution adopted in the utility model is: a kind of excavator boom assembly welding frock, comprise workbench, be arranged at positioner and clamping device on the workbench, described positioner comprises forward and backward supporting positioning component, middle supporting positioning component and rear support positioning component, each assembly is respectively by forming with fixing support of workbench and the support column that is interspersed in the axis hole of support top, each described support column respectively with dipper front and back ends and side plate in the middle part of the corresponding coupling in four hinge hole positions; Described clamping device comprises at least 2 side plate locking devices, each described side plate locking device is made up of location-plate that is positioned at dipper casing to be processed and the retaining mechanism that is arranged at the location-plate both sides, the bottom and the workbench of described location-plate are fixed, and the distance between the left side plate of the width of location-plate and dipper casing is complementary.
In the technique scheme, the casing of described excavator boom to be processed for being welded to form by left and right side plate and upper plate, lower shoe, be respectively arranged with on side plate front and back ends and the middle part and be used for and swing arm, the hinged hinge hole of scraper bowl, four hinge hole positions on described forward and backward supporting positioning component, middle supporting positioning component and the corresponding dipper of rear support positioning component difference, when the welding dipper, support column by each assembly medium-height trestle top is interspersed in the hinge hole of corresponding position, realizes the perpendicular positioning to the dipper left side plate; Described each location-plate is positioned at the casing that is made of side plate and upper plate, distance between its width decision left side plate, left side plate is placed the location-plate both sides respectively, fix by retaining mechanism, this retaining mechanism can adopt prior art, to reach fixed side, make its medial surface be affixed on purpose on the location-plate sidewall, can weld this moment to the upper plate that is placed on the left side plate, the dipper that does not weld lower shoe can be taken off (unclamp clamping device, extract support column out and get final product) after finishing on workbench, stand up, upper plate and interpleural inseam are welded, cover lower shoe after finishing again, carry out integral solder, finish assembly welding.
In the technique scheme, described retaining mechanism is made up of push rod, adjusting nut and pole, and described pole fixedlys connected with workbench, and described push rod is interspersed in the through hole on pole top, and by the adjusting nut location, push rod one end cooperates with the side plate outer surface.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, by forward and backward supporting positioning component, middle supporting positioning component and rear support positioning component four hinge hole location to diverse location on the dipper side plate vertical direction, location-plate in the clamping device is left side plate spacing location, and lock by retaining mechanism, compare with complicated in the past hydraulic pressure frock, the utility model is simple in structure, reduce cost of investment greatly, be particularly useful for the dipper assembly welding that small lot and prepattern are produced;
During 2, owing to employing the utility model assembly welding dipper, take to assemble at last the mode of lower shoe, thereby after to the upper plate surface soldered, can further weld the seam of its inside and left side plate, cover lower shoe at last and finish integral assembly welding, the higher upper plate of welding firmness is carried out the inside and outside dual welding, effectively improved dipper assembly welding quality;
3, because the utility model tool structure is simple, the user of service is not had particular requirement, operate more easyly, practical, and needn't safeguard specially, saved maintenance cost.
