Abstract
The invention discloses a tool for disassembling a double-end stud. The tool for disassembling the double-end stud comprises a rotary sleeve, a screw thread pore plate and a mandril. The rotary sleeve is connected with the mandril in a threaded mode. The screw thread pore plate is detachably connected with the rotary sleeve. A handle part and a screw thread part are sequentially arranged on the mandril from the top to the bottom. The diameter of the handle part is larger than the diameter of the screw thread part. Mandril handles are arranged on the handle part. The rotary sleeve is provided with a first screw thread through-hole, a blind hole and rectangular through-holes. The first screw thread through-hole is communicated with the blind hole. The shaft axis of the first screw thread through-hole and the shaft axis of the blind hole are collinear. The rectangular through-holes are communicated with the blind hole. The rotary sleeve is provided with a second screw thread through-hole. The second screw thread through-hole is communicated with the rectangular through-holes. Fastening screws are arranged in the second screw thread through-hole. The screw thread pore plate is located inside the rectangular through-holes. The rotary sleeve is provided with rotation handles. The screw thread pore plate is provided with multiple screw thread through-holes with different hole diameters The tool for disassembling the double-end stud solves the problem in the prior art that the outer screw thread on the fastened end of the double-end stud can be damaged during the double-end stud disassembling process.
Description
Technical field
The present invention relates to extracting tool field, being specifically related to a kind of instrument for dismantling studs.
Background technology
Studs is connected in Automatic manual transmission field very general application.It is fasteningly be connected part with studs, packing ring, tool body that studs connects, thus it is too thick or should not use bolted occasion due to structural restriction to make studs connection can be applicable to be connected part.Whole precessions one end be connected in the screwed hole of part of studs is called precession end; Another is called fastening end in order to tightening tool body end.During connection, staff needs in the screw of whole for the precession end of stud precession base part, then puts another connected piece, then puts packing ring, tightening tool main body, namely realizes the connection of two connectors.When needs dismounting studs, because the fastening end of studs is also processed with external screw thread, if therefore do not adopt other servicing unit, the simple strength relying on the hand of staff, is not easy studs to disassemble from connector.
At present, in most Automatic manual transmission occasion, staff is threaded in the fastening end of studs the contrary tool body of the thread rotary orientation of a fastened tools main body, staff makes the link of studs screw off from connector by tightening this tool body, but due to when this tool body screws, the helicitic texture of the fastening end of studs will destroy at the joint with fastened tools main body by this tool body, the serviceability of studs is made to be restricted or to lose, even link be threaded be stuck time, in the process screwing this tool body, the fastening end of bolt can be pulled off, thus bring great inconvenience to assembly work.
Summary of the invention
The technical problem to be solved in the present invention be in prior art dismounting studs process in, the impaired problem of external screw thread of the fastening end of studs, a kind of instrument for dismantling studs is provided, when dismantling studs, the feature that fastening end external screw thread can not be destroyed.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: for dismantling the instrument of studs, comprise rotary sleeve, screw thread orifice plate and push rod, described rotary sleeve is threaded with push rod, described screw thread orifice plate and rotary sleeve removably connect, described push rod is followed successively by handle portion and threaded portion from top to bottom, described handle portion diameter is greater than threaded portion, described handle portion is provided with push rod handle, described rotary sleeve is provided with the first tapped through hole, blind hole and rectangular through-hole, described first tapped through hole is communicated with blind hole, and the axial line conllinear of the axial line of the first tapped through hole and blind hole, described rectangular through-hole is communicated with blind hole, described rotary sleeve is provided with the second tapped through hole, described second tapped through hole is communicated with rectangular through-hole, holding screw is provided with in described second tapped through hole, described screw thread orifice plate is positioned at rectangular through-hole, described rotary sleeve is provided with rotary handle, and described screw thread orifice plate is provided with the tapped through hole of multiple different pore size.
Adopting the instrument for dismantling studs in this programme, comprising rotary sleeve, screw thread orifice plate and push rod; Push rod plays a part to withstand studs, and rotary sleeve makes screw thread orifice plate rotate, thus drives studs to rotate, and is extracted by studs from body.Holding screw makes rotary sleeve be connected with screw thread orifice plate.Push rod handle facilitates push rod to rotate.Rotary handle facilitates rotary sleeve to rotate.First screwed hole is communicated with blind hole, is to facilitate push rod to pass rotary sleeve fore-set stud.Apertures different on screw thread orifice plate
Operation principle of the present invention and beneficial effect are: when concrete this extracting tool of use, first rotate the lock-screw on rotary sleeve, screw thread orifice plate can be slided in rectangular through-hole, according to the diameter of thread of the fastening end of the studs that will dismantle, select screw thread orifice plate upper screwed hole, then rotate holding screw and screw thread orifice plate is fixed.Then screw thread orifice plate is threaded with studs, then rotates push rod handle and push rod is moved down, until push rod withstands studs.Then rotate rotary handle, rotary sleeve is rotated, rotary sleeve drives screw thread orifice plate to rotate thus realizes studs and rotates, and finally makes studs extract from body.
Further, the bottom, threaded portion of described push rod is embedded with elastomer block.Push rod push up studs time, offseted by the fastening end of elastomer block and studs, avoid push rod directly to contact the fastening end of studs, damage studs fastening end on silk tooth.
Further, be provided with spring between described push rod and rotary sleeve, and push rod is positioned at spring inner.Avoid rotary sleeve in the process rotated, push rod generation rollback phenomenon, thus cause push rod not tight to studs top.
Further, the screw thread of the threaded portion of described push rod is double thread.The screw rod of double thread revolve turn around relative to single threaded screw rod revolve turn around time, the distance that the screw rod of double thread advances is longer.
Accompanying drawing explanation
Fig. 1 is that the present invention is for dismantling the schematic front view of the device embodiment of studs;
Fig. 2 is the cross-sectional schematic of A-A in Fig. 1.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: rotary sleeve 1, screw thread orifice plate 2, push rod 3, push rod handle 4, spring 5, blind hole 6, rectangular through-hole 7, lock-screw 8, studs 9, body 10, elastomer block 11.
