Abstract
The utility model discloses a broken bolt removal device. The utility model is characterized in that knife edges are arranged on a knife rod. The knife rod is connected with a pressurization stretching rod and a pressing plate polished rod into one body. A screw cap is screwed and welded on the pressing plate polished rod, wherein, the quantity of knife blades can be 2-4 sheets on the knife rod. The specification of the knife rod can be phi 8*10-15 mm. the pressurization stretching rod is a screw thread rod. The specification of the pressurization stretching rod is phi 12* 50 mm. The screw thread tooth distance on the pressurization stretching rod is 1.75 mm. The specification of the pressing plate polished rod is phi 12*12 mm. The utility model has the advantages of easy fabrication, low cost, and convenient operation.
Description
The utility model relates to a kind of Broken bolt removal tool, is specifically related to a kind of specific purpose tool of removing the Broken bolt in screwed hole that fractures in machine-building and maintenance industry.
Bolt plays a part to connect workpiece in mechanical industry, but fractureed situation in screwed hole of bolt occurs through regular meeting for various reasons in operating process, how to take out the Broken bolt in the hole? it is to have become the very problem of headache.The method of taking out Broken bolt at present mainly contains two kinds, a kind of is to bore an aperture on Broken bolt, insert in the aperture with square toes then Broken bolt is back-outed, but if square toes hardness can be slided the angle inadequately and can not get, if it is excessive that square toes quench, often square toes have been twisted into two parts all and Broken bolt can not have been taken out, even may cause screwed hole to scrap; Another kind method is to be drilled to powder with the bolt that drill bit will fracture at screwed hole, then the original thread hole is become the new screw thread of amplifying specification and uses, and doing maximum shortcoming like this is to have destroyed the primary standard design, thereby has influenced mechanical performance.Above-mentioned two kinds of methods had not only been taken a lot of work but also when decreasing, and were if misoperation gently then can influence the precision of workpiece, heavy then can cause workpiece to be scrapped.Said method also is subjected to environmental limit to be not easy to field work in addition.
The purpose of this utility model is to provide a kind of and is easy to carry, Broken bolt remover simple to operate, under the situation that does not have other apparatus to help, only needs remover is screwed in the screwed hole, and Broken bolt taking-up in screwed hole safely, quickly just can will fracture.
Below in conjunction with accompanying drawing and embodiment shown in the drawings thereof, content of the present utility model is described in detail, but content of the present utility model is not limited to shown in the accompanying drawing.
Fig. 1 is a structural representation of the present utility model
The utility model is made of blade (1), knife bar (2), pressurization expansion link (3), pressing plate polished rod (4), screwing up nut (5).Knife bar (2) is provided with blade (1), and connection is as a whole between knife bar (2) and pressurization expansion link (3), pressing plate polished rod (4), the screwing up nut (5).
Wherein the blade on the knife bar (2) is 2～4; The specification of knife bar (2) is 8 * 10～15mm, and pressurization expansion link (3) is a threaded rod, and specification is 12 * 50mm, and the ridge distance on the bar is 1.75mm; The specification of pressing plate polished rod (4) is 12 * 12mm.The size of knife bar and pressurization expansion link also can be selected for use flexibly according to the size of Broken bolt.
Only need during use to clamp screwing up nut (5) with spanner, Broken bolt remover clockwise direction is screwed in the screwed hole, and pressing plate (4) is synchronous with blade (1) pressurization, and blade and Broken bolt promptly are critical, and then, Broken bolt can be taken out from the hole from counter-clockwise direction rotation screwing up nut.
The utility model has solved a mechanical industry and has failed the technical barrier that obtains satisfactorily resolving since the midium or long term always, for a new way has been opened up in effective dismounting of Broken bolt.The utility model manufacturing is simple, cost is low, easy to use, have very good market prospects and promotional value.
Claims (2)
1, a kind of Broken bolt remover, it is characterized in that constituting by blade (1), knife bar (2), pressurization expansion link (3), pressing plate polished rod (4), screwing up nut (5), knife bar (2) is provided with blade (1), and connection is as a whole between knife bar (2) and pressurization expansion link (3), pressing plate polished rod (4), the screwing up nut (5).
2, Broken bolt remover according to claim 1 is characterized in that the blade on the knife bar (2) is 2～4; The specification of knife bar (2) is Φ 8 * 10～15mm; What pressurize expansion link (3) is a threaded rod, and specification is Φ 12 * 50mm, and the ridge on the bar is apart from being 1.75mm, and the specification of pressing plate polished rod (4) is Φ 12 * 12mm.
