Abstract
The utility model belongs to a hardware tool, which can cut rusted nuts without screw rod damage. The utility model is composed of a nut tong head, a cutting knife, an oil cylinder body, a handle, etc., wherein, the cutting knife is fixed on a slide block, the cutting knife and the slide block are arranged in the annular nut tong head together, the oil cylinder body is connected with one end of the nut tong head, an oil cylinder piston is connected with the slide block, and an oil pressure handle and the handle are both connected with the oil cylinder body. An oil cylinder is pressed by the handle, the oil cylinder piston drives the slide block and the cutting knife to move for cutting rusted nuts off, and the rusted nuts are positioned by the nut tong head. Screw rods can be repeated used when rust of the screws is removed or the screws are repaired slightly. The utility model is especially suitable for disassembling screws in ash pillows, screws in clamping plates of steel rails, and screws in turnoff paths in railways.
Description
The utility model relates to a kind of manual hardware ﹠ tools, particularly a kind of be used for because of get rusty, the rust nut cap cutting clamp of non-detachable nut cutting such as screw thread distortion.
Ash pillow screw on railway, railways splint screw, track switch screw etc., because of placing the open air for a long time, be easy to get rusty, the nut of backing off when maintenance work is very hard, general oxygen cutting, the chisel of adopting carved measures such as disconnected nut, and the consequence of doing like this is destructive often, whole sleeper or track switch must be changed, manually wasteful, waste of material is serious.Also have on the fastening facility of some nuts,, make dismounting become a very thorny job because the external force effect causes the screw thread distortion.
The purpose of this utility model is to provide a kind of rust nut cap cutting clamp that the rust nut cap cutting that causes under the above-mentioned situation can not destroyed screw rod.
The utility model project organization is: a kind of rust nut cap cutting clamp, it is characterized in that the nut binding clip that is cut nut by being used to block, can be with the cutter of nut cutting, can promote the slide block that cutter move, piston, cylinder body, and the oil pressure handgrip of pressurization and handgrip formation, cutter are connected on the slide block and one are located in the middle of the nut binding clip, oil cylinder is positioned at nut binding clip one end and connects as a whole, piston is between slide block and cylinder body, and an end is connected with slide block, the other end is connected with cylinder body, oil pressure handgrip one end is connected with piston on the cylinder body and is fixed in the cylinder body middle part, and handgrip one end links to each other with the cylinder body end.Cutter are a triangular prism, and wherein having on connecting rod and the connecting rod on the cylinder has cannelure, and are fixedly connected with screw behind the connecting rod insertion slide block.Cut binding clip ringwise, and an end inner edge is regular hexagon half.
The utility model advantage is can be like a cork with rust nut cap cutting cracking, make screw rod through eliminating rust or doing reparation slightly and can reuse, and package unit uses very convenient, structure is also very simple, the nut that can be used for 16～24mm on ash pillow screw, railways splint screw, the track switch screw also can use the fixing mechanism of other screw.
Fig. 1 is the utility model structural representation.
Fig. 2 is a cutter schematic diagram in the utility model.
Embodiment: the nut binding clip 1 in the utility model is a loop configuration, and an end links to each other with cylinder body 5.The internal diameter of the other end is that half of regular hexagon is so that match with positive six square nuts, slide block 3 places nut binding clip 1 to slide therein, piston 4 passes the nut binding clip and links to each other with slide block 3 one ends, cylinder body 5 one ends link to each other with handgrip 7, piston on the cylinder body 5 links to each other with oil pressure handgrip 6 one ends, and oil pressure handgrip stiff end also links to each other with cylinder body 5 middle parts simultaneously.Cutter 2 are a triangular prism, wherein on the cylinder connecting rod 8 are arranged, and connecting rod 8 not end is shaped on cannelure so that be screwed connection after inserting slide block.Like this, the replacing of cutter is also very convenient.During work, block nut earlier with the nut binding clip, the oil pressure handgrip is the application of force up and down, and oil cylinder piston 4 reaches promote slide block 3 and cutter 2 displacements, make its fracture to being cut nut pressure, and in the correspondence position cutting, nut can be cut in half comes off again.
