Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a Facad structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of overlooking of the present utility model shown in Figure 1;
Fig. 3 is a perspective view of the present utility model.
Be labeled as among the figure: 1, drawing bar, 2, the drawing stem nut, 3, the drawing rod sleeve, 4, cramp bar sleeve, 5, drawbench crossbeam, 6, the cramp bar packing ring, 7, the cramp bar nut, 8, cramp bar, 9, drawing body, 10, the drawbench joint, 11, the rotary bar jack, 12, drawbench joint connecting pin, 13, elongated slot.
The specific embodiment
As Fig. 1, Fig. 2 and the expressed structure of the present utility model of Fig. 3, the utility model is a kind of drawbench, be particularly related to localizing environment more complicated, the drawing needs when irregular, comprise drawbench crossbeam 5, the drawing bar 1 that from the hole of middle part perpendicular to shaft of drawbench crossbeam 5, passes of rectangular cross section, elongated rod shape and be spun on drawing stem nut 2 on the drawing bar 1.The structure of the drawbench of general known technology all comprises above structure.
Because often need in the structure of complexity, some riveting spares be extracted from assembly in the automobile making technology, so need a kind of more convenient, suitable and dexterous drawbench especially.More flexible and purpose easily when the utility model carries out mechanical dismounting in order to be implemented in, on the basis of above-mentioned universal architecture, take following technical scheme with distinguishing characteristics:
The direction at the two ends of drawbench crossbeam 5 to center, respectively establish the elongated slot 13 of a perforation, the plane of symmetry of two elongated slot 13 medial surfaces overlap and also with the dead in line in drawing bar 1 hole of passing, two grooves are openings in the end of drawbench crossbeam 5, respectively establish a cramp bar 8, pass two elongated slots 13 respectively, the plan-position opposite with described drawing stem nut 2 on drawbench crossbeam 5 is provided with the supporting structure greater than groove width on two cramp bar 8 shafts.This structure can make regulating independently of one another as required apart from drawing bar 1 position of two cramp bars 8, change the distance of supporting-point by the elongated slot on the drawbench crossbeam 5 13 apart from the drawing center, rotation by drawbench crossbeam 5 changes the position of supporting-point on the circumference of certain radius, to adapt to the demand of various mounting or dismounting structure.And more convenient and flexible when using, operation is adjusted quick.
The supporting structure of two cramp bars 8 is: establish cramp bar nut 7 on the cramp bar 8, be spun on the cramp bar 8.The purpose of this structure is that the relative altitude of bolt on cramp bar nut 7 and the cramp bar 8 below drawbench crossbeam 5 changes depth of beam, the support height of cramp bar 8 can also be regulated independently of one another, thereby realize that three-dimensional is adjustable, to adapt to the needs of different support height.The relative altitude of cramp bar 8 bottoms can be unequal, this just make two supporting-points not only can with the drawing center not equidistantly but also can not in same horizontal plane, make the location more flexible, can location and drawing apace in the localizing environment of various complexity.
7 on cramp bar nut on two cramp bars 8 need be in same horizontal plane and its distance selects for use after determining the spanner with drawing stem nut 2 corresponding sizes to turn toward the direction of tightening, and realizes the dismounting to riveting spare.
According to technique scheme, an embodiment who the utility model proposes is:
The utility model has also proposed another embodiment:
Drawing body 9 can also adopt with drawbench joint 10 and be threaded.
In order to realize the rotation of drawing body 9, drawing body 9 is provided with horizontal rotary bar jack 11 on its shaft, and this hole is a through hole.In use, diameter is inserted this hole less than the regulating rod in this hole, be rotated adjusting.During operation, if turning drawing stem nut 2 carries out finding to have the phenomenon of blocking in the process of drawing, selecting for use the rod iron of a Φ about 8 to be inserted in the rotary bar jack 11 pulls toward both sides, make by the object of drawing and rotate, so not only can prevent to be blocked but also can make drawing process lighter by foreign matter in the drawing process around its center.
Establish drawing rod sleeve 3 on the drawing bar 1, its structure is the sleeve that has chimb, hole on the endoporus of drawing rod sleeve 3 and drawing bar 1, cylindrical and the drawbench crossbeam 5 is matched in clearance, and the chimb of described drawing rod sleeve 3 is between the plane of the end face of drawing stem nut 2 and drawbench crossbeam 5.This structure makes between drawing bar 1 and the drawbench crossbeam 5, the friction between drawing stem nut 2 and the drawbench crossbeam 5 reduces.
Establish cramp bar sleeve 4 on the shaft of cramp bar 8 and place in the elongated slot 13, the groove width of the shaft of the endoporus of cramp bar sleeve 4 and cramp bar 8, cylindrical and elongated slot 13 is matched in clearance.This structure reduces the friction between cramp bar 8 and the drawbench crossbeam 5.
If cramp bar packing ring 6, described cramp bar 8 pass the hole of cramp bar packing ring 6 and for matched in clearance, the position of cramp bar packing ring 6 is between the plane of the end face of cramp bar nut 7 and drawbench crossbeam 5.This structure reduces the friction between cramp bar nut 7 and the drawbench crossbeam 5.
The utility model has realized that the translation of three-dimensional rotation adjustable and horizontal direction is adjustable, but flexible positioning, and save time, easily and effectively in location and realize the drawing function apace in rule or irregular structure apace.Simple in structure, easy to process, safe and reliable, inexpensive practicality is conveniently effectively mixed and variously directly and other common tool (as various spanners etc.) interface is farthest used existing standard component, and cost is low, high efficiency.Simultaneously also can realize various drawing needs by the various joint of changing-over.In automobile making technology, just can very easily the fuel injector that is bonded on the cylinder cap be pulled out as the utility model being mixed the fuel injector clip connector.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
