Description
Technical field
The utility model relates to a kind of boring grab, particularly relates to a kind of end board assembly boring grab.
Background technology
In steel building, support applications is extensive, but the complex structure of support end board component, and on doubly-linked fishplate bar face, the accuracy of lower opening position has material impact to the installation accuracy of building and quality.At present, weld after usually first being holed by the connecting plate of end board assembly end, because welding very easily causes members contract to be out of shape, make the depth of parallelism of welding two pieces of connecting plates after shrinking not easily control, upper lower opening position offsets again; And if first weld carry out again line boring, because the connecting plate of end board assembly end is too little, rule inaccurate, waste time and energy, complex operation.
Therefore, need to propose a kind of new scheme and solve above-mentioned technical problem.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, and easy to assembly, borehole accuracy is high, and easy to operate end board assembly boring grab.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of end board assembly boring grab, comprise base, Zuo Mo, right mould and bushing plate, left mould and right mould are separately fixed at base two ends, left mould top is provided with groove, the bottom center of groove has lower through-hole, positioning component is provided with in groove, baffle plate is provided with between left mould and right mould, on baffle plate, symmetry has two through holes, the top of left mould and right mould by bolt and bushing plate affixed, the position of the corresponding lower through-hole of bushing plate has through hole, the position of the corresponding through hole of this bushing plate has the drill bushing hole for fixing drill bushing, bushing plate between drill bushing hole also has Y shape notch.
Described positioning component comprises cam, handle, push rod and bearing pin, and push rod and handle are horizontally fixed on cam both sides respectively, and bearing pin is through cam, and its two ends are inserted in lower through-hole and upper through hole respectively.
Top and the bottom of described cam are equipped with pad.
The utility model has the advantages that: this boring grab structure is simply novel, assembling and easy to operate, can hole to the microsize connector of end board assembly end, effectively improve precision and the efficiency of boring, without the need to line location, save trouble and labor, is adapted at promoting the use of in this area.

Wherein, 1, base, 2, Zuo Mo, 21, lower through-hole, 3, right mould, 4, baffle plate, 41, through hole, 5, bushing plate, 51, bolt, 52, Y shape notch, 53, upper through hole, 6, drill bushing, 61, drill bushing hole, 7, cam, 71, handle, 72, bearing pin, 73, push rod, 8, end board assembly, 81, connecting plate, 82, stiffener.
Detailed description of the invention:
As shown in Figures 1 to 4, a kind of end board assembly boring grab, comprise base 1, left mould 2, right mould 3 and bushing plate 5, left mould 2 and right mould 3 are separately fixed at base 1 two ends, left mould 2 top is provided with groove, the bottom center of groove has lower through-hole 21, positioning component is provided with in groove, baffle plate 4 is provided with between left mould 2 and right mould 3, on baffle plate 4, symmetry has two through holes 41, the top of left mould 2 and right mould 3 is affixed by bolt 51 and bushing plate 5, the position of the corresponding lower through-hole 21 of bushing plate 5 has through hole 53, the position of the corresponding through hole of this bushing plate 5 41 has the drill bushing hole 61 for fixing drill bushing 6, bushing plate 5 between drill bushing hole 61 also has Y shape notch 52, positioning component comprises cam 7, handle 71, push rod 73 and bearing pin 72, push rod 73 and handle 71 are horizontally fixed on cam 7 both sides respectively, bearing pin 72 is through cam 7, and its two ends are inserted in lower through-hole 21 and upper through hole 53 respectively, and top and the bottom of cam 7 are equipped with pad.
As shown in Figure 5, the end of end board assembly 8 is provided with about two pieces parallel connecting plates 81, and need hole thereon, every block connecting plate 81 outer surface central authorities are also welded with stiffener 82.
Shown in Fig. 6, when using above-mentioned boring grab to hole to connecting plate 81, first the base 1 of boring grab is fixed on the platform of radial drilling machine equipment, will is clipped on baffle plate 4 outside connecting plate 81 afterwards, stiffener 82 embeds in Y shape notch 52, and drill bit can be utilized by positioning component after being locked to hole.
In above-mentioned boring grab, the aperture of through hole 41 is greater than the footpath, cross section of drill bit, for avoiding drill bit, prevents drill bit to the damage of baffle plate 4, and the distance of itself and baffle plate 4 periphery is as the criterion with the boring requirement of reality to end board assembly 8; Drill bushing 6 improves hardness through Quenching Treatment, effectively prevent the wearing and tearing between drill bit and bushing plate 5; The handle 71 of positioning component can rotate around bearing pin 72, is convenient to realize clamping between end board assembly 8 and boring grab and unclamps, and during clamping, cam 7 holds out against the top flange of connecting plate 81, and when unclamping, end board assembly is released this boring grab by push rod 73 automatically; Cam 7 top and bottom are all provided with pad, to reduce the contact area between cam 7 and this boring grab, handle 71 of being more convenient for rotates, and bushing plate 5 and left mould 2 are all provided with fillet, when avoiding operating, hand scratch, further increases the processing safety of above-mentioned boring grab.
