So-called steel construction piece is by welding, riveted joint or and the parts of steel construction that link into an integrated entity of the various ways such as bolt connection, these steel construction pieces link mutually, condition each other again, form an organic steel construction entirety.In general, steel construction piece is prefabricated processing in the factory, then moves to job site and carry out Assembling and installation.General conventional assembling and mounting means are weld seam, bolt or rivet interlacement.Time with bolts, need to hole on steel construction piece in advance, thus process the through hole passed for bolt.Owing to being limited to the installation quality of in-site installation environment and workman, needing to ensure high borehole accuracy, once there is skew, the problem that scene cannot be installed can be caused, therefore, need the boring grab that a kind of correspondence is provided for special steel construction piece.
Utility model content
The purpose of this utility model is to provide a kind of steel construction piece boring grab, can position steel construction piece to be processed and fixed clamp, ensures the precision of boring.
For achieving the above object, the technical solution of the utility model is: steel construction piece boring grab, comprise the base of rectangle, described base is provided with detent mechanism and clamping device, described detent mechanism includes two positioning seats be fixed on the longitudinal centre line of base, described two positioning seats distribute along the cross central line axial symmetry of base, positioning seat described in described positioning seat is arranged with the alignment pin of annular, the end of described positioning seat is provided with the baffle plate preventing alignment pin from deviating from, and the below described positioning seat being positioned at alignment pin is provided with stage clip; Described clamping device comprises horizontal clamping device and longitudinal clamping device, and described horizontal clamping device comprises rotating bidirectional rotation fixture block and horizontal grip block, and described bidirectional rotation fixture block is positioned at the top of horizontal grip block; Described longitudinal clamping device includes rotating single direction rotation fixture block and longitudinal grip block, and described single direction rotation fixture block is positioned at the top of longitudinal grip block, and the top end face of described horizontal grip block and longitudinal grip block is located in the same horizontal plane.
When adopting technique scheme, by arranging detent mechanism and clamping device, can respectively steel construction piece to be processed be positioned and be clamped.Wherein, when locating, be played a major role by alignment pin.During clamping, be by rotating bidirectional rotation fixture block and single direction rotation fixture block, being rotated to clip position, and the horizontal grip block of below correspondence and longitudinal grip block carry out coordinating and to clamp steel construction piece and locate.The utility model structure is simple, effectively can be clamped by shirtsleeve operation to steel construction piece to be processed, and accurate positioning, the precision that steel construction piece is holed can be guaranteed, be beneficial to the installation and removal in later stage.
Further, described bidirectional rotation fixture block and single direction rotation fixture block are driven by corner oil cylinder.By driving corner oil cylinder, the automaticity of clamping device can be improved, and certain torque can be provided man-hour adding, prevent because processing is stressed and deflect.
Further, describedly on base, be provided with two horizontal clamping devices be positioned on cross central line, described two horizontal clamping devices are symmetrical arranged along the longitudinal centre line of base.
Further, describedly on base, be provided with two longitudinal clamping devices be positioned on longitudinal centre line, described two longitudinal clamping devices are symmetrical arranged along the cross central line of base.Above-mentioned two settings can ensure each mechanism location, accurate position on base, are convenient to position and process.
Further, the angle between two isometry blocks of described horizontal clamping device is 60 °.The angle of 60 ° is set, isometry block can be made to avoid corresponding structural member, and the area of clamping can be increased, improve the stability of clamping.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the perspective view of the utility model steel construction piece boring grab embodiment.
Reference numeral: base 1, base fixing hole 11, positioning seat 2, baffle plate 3, alignment pin 4, stage clip 41, corner oil cylinder 5, bidirectional rotation fixture block 51, single direction rotation fixture block 52, isometry block 6.
Detailed description of the invention
As shown in Figure 1, the utility model steel construction piece boring grab, includes base 1, base 1 has been offered multiple base fixing hole 11, for base 1 is fixed on frame.Base 1 is fixed with detent mechanism and clamping device, wherein, detent mechanism includes positioning seat 2, the top of positioning seat 2 forms a baffle plate 3 protruded, positioning seat 2 slides and is provided with an annular alignment pin 4, a stage clip 41 is provided with between alignment pin 4 and the bottom of positioning seat 2, by stage clip 41, alignment pin 4 is tightly pressed in the lower end of the baffle plate 3 on positioning seat 2 top, baffle plate 3 plays a spacing effect, prevent alignment pin 4 from deviating from from positioning seat 2, during location, by pressure alignment pin 4, expose positioning seat 2 and upper end-stopping plate 3 positions, alignment pin 4 can play the effect of a clamping.On base 1, be wherein provided with two positioning seats, 2, two positioning seats 2 be all positioned on the center line of base 1, and be symmetrically distributed on base 1.Clamping device includes horizontal clamping device and longitudinal clamping device.Horizontal clamping device includes corner oil cylinder 5, and the piston rod of corner oil cylinder 5 is fixed with bidirectional rotation fixture block 51, bidirectional rotation fixture block 51 is arranged symmetrically with on the piston rod.Also have two isometry blocks 6 being symmetrically distributed in corner oil cylinder 5 both sides in horizontal clamping device, isometry block 6 is fixed on base 1 by the mode of the fixing hole construction bolt bottom it.In order to obtain best clamping effect, between isometry block 6 and corner oil cylinder 5, there is the angle of 30 °.When bidirectional rotation fixture block 51 is positioned at clip position, the two ends of bidirectional rotation fixture block 51 lay respectively at the top of the isometry block 6 of corner oil cylinder 5 both sides.Base 1 secures altogether two horizontal clamping devices, and two horizontal clamping devices are symmetrical arranged along the longitudinal centre line of base 1.Also include a corner oil cylinder 5 in longitudinal clamping device, the piston rod of corner oil cylinder 5 is fixed with single direction rotation fixture block 52.Also have an isometry block 6 being distributed in corner oil cylinder 5 side in longitudinal clamping device, when single direction rotation fixture block 52 is positioned at clip position, the bare terminal end of single direction rotation fixture block 52 is positioned at the top of the isometry block 6 of corner oil cylinder 5 side.Base 1 secures altogether two longitudinal clamping devices, two longitudinal clamping devices being laterally symmetrical arranged to center line along base 1.Further, corner oil cylinder 5, single direction rotation fixture block 52 and positioning seat 2 are positioned on straight line.
