Abstract
The utility model belongs to the mechanical operation tool, and provides a tool for dismounting an eccentric wheel type threaded stud. The tool mainly comprises a tool body (1), an eccentric wheel (2)and an eccentric wheel core shaft (3), wherein a cylindrical inner hole matched with a threaded stud is formed on the tool body (1); a rectangular hole running through the cylindrical inner hole is formed on the tool body (1); the eccentric wheel (2) corresponds to the rectangular hole, and is connected with the tool body (1) after penetrating through the eccentric wheel core shaft of the eccentric hole; and a handle (4) used for manually screwing and dismounting the threaded stud is arranged on the tool body (1). The tool has the advantages of reasonable design and simple structure, and ensures simple and convenient screwing and dismounting operation of the threaded stud during overhaul of mechanical equipment by utilizing the quick clamping and self-locking functions of the eccentric wheel, thereby reducing the labor intensity and enhancing the working efficiency.
Description
Technical field
The utility model belongs to a kind of mechanical work instrument, relates generally to a kind of eccentric wheel type studs dismantling device.
Background technology
In railway locomotive and plant equipment service work, the studs amount ratio is more, but since the columniform profile of studs, the inconvenience that often brings disassemble and assemble work to the operating personnel.The common assembly and disassembly methods of studs is at studs one end the method that is equipped with tight a pair of nut mutually to be installed to tighten and dismantle, but this method of operating is time-consuming effort again, has also increased labour intensity, is unfavorable for increasing work efficiency.
The utility model content
The purpose of this utility model is to propose a kind of eccentric wheel type studs dismantling device, and it is simple in structure, easy to operate that it is had, and then have the high characteristics of efficient.
The utility model realizes that the technical scheme that its goal of the invention is taked is: a kind of eccentric wheel type studs dismantling device, it mainly comprises tool body, eccentric wheel and eccentric wheel mandrel, described tool body has the cylindrical bore with the studs coupling, on tool body, has the rectangular opening that connects with its cylindrical bore, eccentric wheel eccentric wheel mandrel corresponding with rectangular opening and through passing its eccentric orfice is connected with tool body, on tool body, also be provided with handle, in order to manual rotation dismounting studs.
The utility model is reasonable in design, and is simple in structure, utilizes eccentric wheel to clamp fast and self-locking action, make the disassemble and assemble work of studs in the plant equipment maintenance process easy and simple to handle, and the labour intensity that has reduced has improved operating efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, tool body, 2, eccentric wheel, 3, the eccentric wheel mandrel, 4, handle.
The specific embodiment
The embodiment that provides is in conjunction with the accompanying drawings further specified the utility model:
Embodiment 1: as shown in the figure, the utility model mainly is made of tool body 1, eccentric wheel 2 and eccentric wheel mandrel 3, described tool body 1 has the cylindrical bore with the studs coupling, on tool body 1, has the rectangular opening that connects with its cylindrical bore, edge along tool body 1 rectangular opening has the lug of taking turns mandrel 3 in order to setting-up eccentricity, wherein, lug can adopt the mode of welding to be connected with tool body 1; Eccentric wheel 2 and eccentric wheel mandrel 3 through pass its eccentric orfice corresponding with rectangular opening is connected with lug on the tool body 1, also is provided with handle 4 on tool body 1, in order to manual rotation dismounting studs; Studs with M5 is an example, and eccentric wheel 2 of the present utility model can be quenched by No. 45 steel annular knurls and form, and offset can be 0.75, and the eccentric wheel mandrel is made by Ф 3 steel rivets, and mandrel and eccentric wheel hole are matched in clearance, and the gap is 0.05mm, and eccentric wheel can rotate flexibly.The centre-to-centre spacing of the cylindrical bore of eccentric wheel mandrel hole and tool body 1, determine by eccentric offset, with at the offset minimum position, guarantee that studs can normally penetrate, eccentric wheel is locked studs at offset during near maximum position, reach the purpose of studs and tool body interlock, realize the studs mounting or dismounting.Eccentric wheel should be under structure permission situation, strengthen as far as possible, eccentric throw is as far as possible little, pressure angle in the time of can reducing eccentric wheel locking like this makes reliable lock, and eccentric wheel is reliably self-locking also, make when changing the hand conversion in the operating process, unlikely eccentric wheel is thrown off, and opposite spin when putting in place, can be easy to throw off; Tight fit is adopted in mounting or dismounting tools and handle assembling, and can add stop pin, and handle adopts wooden file handle, makes operation light; When workload is big, can remove the wooden handle of eccentric wheel type studs dismantling device, the awl tail is changed into outer hexahedron, be connected with electric tool, to increase work efficiency.
Embodiment 2: adopt the method for grooving on the tool body 1 of present embodiment in order to the lug of setting-up eccentricity wheel 2, and unnecessary material forming on the removal tool body then, other structure and implementation method are identical with embodiment 1.
The course of work of the present utility model is: when operation, in putting into studs in the cylindrical hole of the present utility model, move in the direction of the clock, eccentric wheel is locked studs by frictional force, rotation the utility model can be tightened studs, after installing, only need counter-rotation once, eccentric wheel will unclamp.Principle is identical during the dismounting studs, only needs to press the disassembly direction rotation and gets final product.
Claims (1)
1, a kind of eccentric wheel type studs dismantling device, its principal character is: it mainly comprises tool body (1), eccentric wheel (2) and eccentric wheel mandrel (3), described tool body (1) has the cylindrical bore with the studs coupling, on tool body (1), has the rectangular opening that connects with its cylindrical bore, eccentric wheel (2) and eccentric wheel mandrel (3) through pass its eccentric orfice corresponding with rectangular opening is connected with tool body (1), also is provided with the handle (4) in order to manual rotation dismounting studs on tool body (1).
