The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Fig. 2 and Fig. 8 a, 8b, according to crane arm apparatus for assembling of the present utility model, comprise assembly platform 10, be provided with a plurality of V-shape bases 20 that position for the lower cover 63 to crane arm 60 on assembly platform 10, a plurality of V-shape bases 20 are located along the same line; The crane arm apparatus for assembling also comprises a plurality of positioners that are embedded in lower cover 63 inboards, and the upper cover plate 61 of crane arm 60 is set in the outside of positioner.The utility model is by arranging V-shape base 20 location lower covers 63 on assembly platform 10, and be embedded positioner in lower cover 63 inboards, upper cover plate is set on positioner, thereby locate the relative position of upper cover plate 61 and lower cover 63 by positioner, the center line of upper cover plate 61 and lower cover 63 is overlapped, improve the assembly precision of crane arm, thereby guarantee the performance of crane arm.
Preferably, positioner comprises at least two location-plates 30 that are embedded respectively at lower cover 63 two ends, location-plate 30 is symmetrical about the center line of lower cover 63 and upper cover plate 61, even lower cover 63, upper cover plate 61 and location-plate 30 are all symmetrical about the center line of location-plate, three's center line is located along the same line, thereby the center line of upper cover plate 61 and lower cover 63 is overlapped.
As shown in Fig. 9 a, the top of location-plate 30 is provided with the hypotenuse 31 of stepping down of the fillet that gets out of the way upper cover plate 61 inboards, thereby prevent top and the inboard formation interference of upper cover plate 61 of location-plate 30, the processing hypotenuse 31 of stepping down is compared the arc-shaped edges that coordinates with fillet of processing and can effectively be improved working (machining) efficiency in addition, thereby reduces production costs.
As shown in Fig. 9 a, the bottom of location-plate 30 is provided with and the inboard arc-shaped edges 32 that coordinates of lower cover 63, thereby the bottom of location-plate 30 and lower cover 63 inboards are closely clamped together, prevent when sheathed upper cover plate 61, skew occurs and causes positioning accuracy to reduce in location-plate 30.
Preferably, as shown in Fig. 9 a, also be provided with the notch part 33 of dodging the weld seam 62 between upper cover plate 61 and lower cover 63 on location-plate 30, by being set, notch part 33 can prevent that the burr at upper cover plate 61 and lower cover 63 edges from affecting the installation accuracy of location-plate 30, simultaneously, in the time of also can preventing from welding, location-plate 30 and upper cover plate 61 and lower cover 63 be welded together.In order to improve the machining accuracy of location-plate 30, the edge of whole location-plate 30 can adopt the line cutting processing, improves machining accuracy, thereby the edge that guarantees location-plate is symmetrical about its center line.
As shown in Fig. 9 b, the V- arrangement limit 21,23 of V-shape base 20 is about center line 22 symmetries of V-shape base 20, perhaps the angular bisector at the V-arrangement angle of V-shape base is positioned at perpendicular, thereby make lower cover 63 can center line can be vertical, the open side of namely adjusting quickly and easily lower cover 63 is to level, guarantees the flatness on the upper plane of the upper cover plate 61 that welds on open side.The overall structure that V-shape base 20 can be formed in one also can adopt two pedestals with hypotenuse that the both sides of lower cover 63 are set respectively, thereby form a V-shape base 20.
Usually, V-shape base 20 is two, and in order to facilitate the setting of V-shape base 20, generally take the center line of assembly platform 10 as benchmark, namely the center line of V-shape base 20 overlaps with the center line of assembly platform 10.Two V-shape base 20 operated by rotary motion are in the position near the two ends of lower cover 63, thereby lower cover 63 is formed positioning supports.
In order to facilitate leveling to be positioned at lower cover 63 and the upper cover plate 61 of V-shape base 20, the crane arm apparatus for assembling also comprises levelling device.Levelling device comprises the height measuring rule 40 that is positioned at lower cover 63 both sides, as shown in Fig. 9 c, the rectangular triangle of height measuring rule 40, has indicating graduation 41 on its long right-angle side, the height measuring rule 40 of right angle trigonometry shape can more easily make indicating graduation 41 be vertical state, thereby makes measuring height accurately.Height by contrast lower cover 63 and upper cover plate 61 both sides makes lower cover 63 consistent at the height of both sides with upper cover plate 61, can guarantee the horizontal accuracy of lower cover 63 and upper cover plate 61, i.e. the flatness on the upper plane of upper cover plate 61.Preferably, the crane arm apparatus for assembling also comprises the horizon rule 50 that coordinates with height measuring rule 40, horizon rule 50 is placed on the upper plane of the open side of lower cover 63 or upper cover plate 61, measure the height at horizon rule 50 two ends by height measuring rule 40, can be more quickly with lower cover 63 and upper cover plate 61 leveling.Levelling device also can adopt other horizontal measuring instrument, as air-bubble level, perhaps other etc.
Adopt the application's crane arm apparatus for assembling to assemble in the process of crane arm, specifically comprise the following steps:
As shown in Fig. 3 a and Fig. 3 b, at first draw center line on assembly platform 10, two V-shape bases 20 are separated by a distance, and the center line that its center line and assembly platform 10 are drawn overlaps, thus the center line that guarantees two V-shape bases 20 is point-blank.
Then as shown in Fig. 4 a and Fig. 4 b, be positioned on two V-shape bases 20 crane arm 60 lower covers 63 are opening up.And as shown in Fig. 5 a and Fig. 5 b, adopt height measuring rule 40 and be used in conjunction with horizon rule 50 with lower cover 63 leveling.
As shown in Fig. 6 a and Fig. 6 b, embed location-plates 30 at lower cover 63 two ends, preferably the position is the position of 200mm roughly apart from two ends, thus dismounting location-plate 30 after can ease of assembly completing.
As shown in Fig. 7 a and Fig. 7 b, upper cover plate 61 is inserted in outside location-plate 30, dock with lower cover 63, by location-plate 30, guarantee that upper cover plate 61 overlaps with the center line of lower cover 63.And as shown in Fig. 8 a and Fig. 8 b, adjust the flatness of upper cover plate 61 by height measuring rule 40 and horizon rule 50, and guarantee that the flatness of crane arm 60 meets design requirement, then with upper cover plate 61 and lower cover 63 welding, complete assembling.
