Abstract
The utility model relates to a simple fastening fixture for steel plate drilling and belongs to drilling fixtures. The simple fastening fixture for steel plate drilling is characterized by mainly comprising a clamping frame, a mother nut, a pressing-down screw and a pressing head. The clamping frame is in a right-angled groove shape. The clamping frame is mainly composed of an oblong right vertical plate, a horizontally left-stretched oblong upper cantilever slab and a horizontally left-stretched bottom plate, which are integrated. The upper cantilever slab is short, the bottom plate is long, the left section of the bottom plate is rectangular, and the right section of the bottom plate is oblong. The mother nut is welded to the left end of the upper cantilever slab, and an axial central line of the mother nut is downwardly perpendicular and is correspondingly located in the middle of the left section of the bottom plate of the clamping frame. The pressing-down screw is rotatably disposed in the mother nut, the upper end of the pressing-down screw is a square section, and the lower end of the pressing-down screw is a ball section. The oblong pressing head is mounted on the ball section of the pressing-down screw, and accordingly the pressing head does not fall off when the pressing-down screw is lifted, and the existing small-sized drilling machine is convenient and safe.
Description
Technical field
The utility model belongs to boring jig, relates in particular to the boring fastening jig of a kind of steel plate.
Background technology
In structure steel fabrication factory; Can be equipped with small drilling machine mostly, and large-sized drill machine is low and cost an arm and a leg generally and seldom to be equipped with because of utilization rate, but in the structure steel fabrication process, can relates to the boring of large-scale steel structure column base plate usually; The size of this base plate is often very big; Generally can't fix with small drilling machine boring, entrust to the producer with large-sized drill machine usually and process, it is also expensive not only to waste time and energy.
Summary of the invention
The purpose of the utility model is to propose the boring simple and easy fastening jig of a kind of steel plate, and is simple and reasonable, easy to use, safe, cooperates existing small drilling machine to the boring of steel structure column base plate, and saving of work and time is saved cost.
The purpose of the utility model realizes like this: the boring simple and easy fastening jig of a kind of steel plate (being called for short simple and easy fastening jig); It is characterized in that the boring simple and easy fastening jig of this steel plate mainly is made up of holding frame, mother nut, depress spiro rod and pressure head; The rectangular flute profile of this holding frame; The rectangle upper cantilever plate that this holding frame is mainly stretched by a rectangular right riser of processing one and a level left side, the base plate that stretch on a level left side are formed; This upper cantilever plate is short and base plate is long, rectangular and right section of the left side section of this base plate be rectangle (left side section that is base plate is higher than right section), and this holding frame can be formed by gas welding cutting by the thick steel plate of 30mm; At the left end of the upper cantilever plate mother nut that is welded; This mother nut can be the nut of M30, makes the also corresponding vertically downward middle part that is positioned at holding frame base plate left side section of longitudinal center line of this mother nut, spinning depress spiro rod in mother nut; The upper end section of this depress spiro rod is the bulb section for section lower end, four directions section; Offer the pressure head of the cuboid of center spherical groove in the bulb Duan Shangyong of depress spiro rod dissection type Kraft and the bolt equipped correspondence of sliding, or the outside left that correspondence is positioned at depress spiro rod ball neck on the top of pressure head holes respectively and fixedly install bearing pin (spot welding), pressure head does not come off when the lifting depress spiro rod.
During use; Earlier the depress spiro rod of the boring simple and easy fastening jig of this steel plate is revolved and rise to maximum height, again steel plate and steel plate fixture (seat) are inserted in the bayonet socket of simple and easy fastening jig, twist cubic section with spanner and tighten depress spiro rod; Steel plate is fastening, hole with small drilling machine then.
The boring simple and easy fastening jig of the steel plate that the utility model proposed, simple and reasonable, easy to use, safe, fully use existing small drilling machine, saved the structure steel fabrication cost.
Combine accompanying drawing and embodiment that the boring simple and easy fastening jig of the steel plate that the utility model proposed is described further at present.
