Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Among the figure: 1 hold down gag, 2 motor reducers, 3 pinions, 4 locknuts, 5 leading screws, 6 keys, 7 gear wheels, 8 screws, 9 bearings, 10 bearings, 11 slide masses, 12 hook plates, 13 directive wheels, 14 running gears, 15 crossbeams, 16 compress leading screw, 17 moulding beds, 18 base plates, 19 webs, 20 panels.
The specific embodiment
Below in conjunction with figure and preferred embodiment, details are as follows to the specific embodiment, structure, feature that foundation the utility model provides:
As shown in Figure 1-Figure 3, this is used for the spot welding hold-down mechanism of box beam panel and web (is example with the crane box beam), comprise be used to compress panel 20 and web 19 be symmetrically arranged left and right sides hold down gag 1, left and right sides hold down gag 1 comprises: motor reducer 2, pinion 3, gear wheel 7, screw 8, locknut 4, leading screw 5, metal (upper 9 and 10, slide mass 11, hook plate 12, directive wheel 13; Described motor reducer 2 coaxial connection pinions 3 and be fixed on press device 1 top, described pinion 3 and a gear wheel 7 engagements, described gear wheel 7 is connected with screw 8 by key 6 and makes gear wheel 7 fixing with screw 8 by locknut 4, have bearing 9 and bearing 10 on the described screw 8 and be installed in hold down gag 1 inside, spacing screw 8 can only rotate and can not do radial motion, described screw 8 is connected with leading screw 5, when leading screw 8 rotates at screw 8, can only move up and down, leading screw 5 bottoms are connected with guiding slide mass 11, described slide mass 11 does not rotate when guaranteeing that leading screw 5 moves up and down, the slideway of slide mass 11 is arranged on hold down gag body bottom, and described slide mass 11 bottoms are connected with hook plate 12; Described hook plate 12 has two elongated slots in order to hook box beam base plate 18 on the described hook plate 12, and a stator wheel 13 respectively is housed in two grooves, and described directive wheel 13 is to roll with box beam base plate 18 both sides and cooperates, and plays the correcting effect.Box beam base plate 18 belows are moulding bed 17.
The operation principle of hold down gag is: motor reducer drives gear wheel 7 rotations that 3 rotations of 2 band pinions drive its engagement, gear wheel 7 rotations drive screw 8 rotations again, impel leading screw 5 and slide mass 11, hook plate 12 etc. to move up, reach the purpose that hook plate 12 hooks box beam base plate 18.
Left and right sides hold down gag 1 can pass through motor reducer 2 synchronous or asynchronous drivings, middle by crossbeam 15 connections, bottom, two ends, crossbeam 15 left and right sides is established a running gear 14 respectively, the driven pulley that left and right sides running gear 14 is respectively established a driving wheel and is mated, driving wheel relies on splined shaft directly to drive by motor reducer 2, and two pressure points also respectively are set on the left and right sides running gear 14, and pressure point constitutes by manually compressing leading screw 16, the effect of pressure point is: the firstth, compress panel, and the secondth, do not allow road wheel stressed.
During application, this mechanism is positioned on the box beam, hook plate 12 below left and right sides hold down gag 1 hooks two pressure points that are provided with on box beam base plate 18 and the running gear 14, manually compressing leading screw 16 makes left and right sides road wheel (comprise driving wheel and the driven pulley that is mated) break away from the box beam panel to allow and compress leading screw 16 and compress box beam panel 20, promptly compress, make panel 20 and web 19 to fit tightly up and down, reach the fixing purpose of spot welding.
In the operation, spot welding finishes a place, unclamp the thrust of 1 pair of box beam base plate of hold down gag, and the leading screw 16 that compresses of four pressure points of manual adjustments makes the left and right sides four wheels of running gear 1 be pressed onto the box beam panel, reach till the own wt that bears left and right sides hold down gag 1; By opening travel driving unit, drive left and right sides hold down gag 1 and be advanced to next welding place; Operation by that analogy can guarantee effectively that just the whole box beam panel 20 and the spot welding of web 19 compress the implementation result highly significant.
Above-mentioned with reference to embodiment to the detailed description that this spot welding hold-down mechanism that is used for box beam panel and web carries out, be illustrative rather than determinate; Therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
