Abstract
The utility model discloses a series assembling and disassembling tool for stud, comprising a spanner, a spanner base, an outer sleeve, an inner cam, a roller clamp, a roller, etc. The roller rolls in the track of the inner cam for reducing the radial position in order to clamp the polished rod of a stud for assembling and disassembling the stud. The utility model has the advantages of simple structure, convenient operation, high efficiency and good versatility. The series assembling and disassembling tool for stud is suitable for assembling and disassembling bolts with various formats, and the series assembling and disassembling tool for stud is a necessary tool used for tractors and automobiles in mechanical industry.
Description
The utility model relates to machinery mounting or dismounting hardware ﹠ tools.
The application of stud on tractor, automobile is very extensive, as cylinder bolt, bolt of bearing cap, final drive casing bolt or the like.These diameters of bolt vary in size, the installation position steric requirements is different, also each is variant in the requirement of damaged condition and replacing.Because the clamping inconvenience of stud, therefore mounting or dismounting are relatively more difficult.In the prior art, the method for two mutual pretensions of identical nut of people's extensive use, this method needs two general utility wrenches, and efficient is lower.Also have a kind of wrench body to replace a nut with the band handle, clamping screw with the band handle replaces the another nut, and this method does not need special spanner, but efficient is still very low, and all be the mounting or dismounting tools that is clamped in threaded portion, easily cause the tooth line of bolt to destroy.Also have a kind of fast quick-mounting knife structure that adopts reamer to realize the instrument that screws in and the instrument of motor-driven screw-in, these instruments can only solve screw-in and can not solve and pull down, and motor-driven complex structure.
The purpose of this utility model is to provide a kind of simple in structure, mounting or dismounting are convenient, efficient is high a kind of stud series mounting or dismounting tools that utilizes the clamping of polished rod part in order to overcome weak point of the prior art to society.
Accompanying drawing of the present utility model is a stud series mounting or dismounting tools structure chart.
Embodiment is described in detail the utility model below in conjunction with accompanying drawing.
Stud series mounting or dismounting tools is the quick mounting or dismounting tools of clamping polished rod part.In the spanner seat (8) of strap wrenches (11) cam ring (4) is housed, the steel ball (3) in spanner seat (8) and cam ring (4) mating surface is arranged in the through hole of spanner seat (8) radial equipartition and the steel ball nest of cam ring (4) radial equipartition.Roller folder (5) is housed in the cam ring (4), and it has the axial dovetail groove of radial equipartition, and roller (6) is positioned at the dovetail groove of roller folder (5).The effect of steel ball (3) is that spanner seat (8) drives cam ring (4) rotation by steel ball (3), simultaneously, when needs transposing cam rings (4) wait other part, upwards promote the spacing place of overcoat (7) to shaft block ring (1), make steel ball (3) fall into the breach of overcoat (7), at this moment cam ring (4) can unload.The roller folder (5) that is positioned at cam ring (4) has the axial dovetail groove of radial equipartition, and roller (6) is arranged in this groove.For preventing to scurry on roller folder (5) is when working, hole back-up ring (2) is housed in cam ring (4).The steel ball of present embodiment (3) all is advisable with three with roller (6).Different length according to the stud bolt thread part, reach spacing purpose by adjusting with the height and position that chapiter screw (10) is fastened on the limited post (9) in the spanner seat (8), guarantee when the identical bolt of mounting or dismounting specification, can be clamped in the polished rod position, avoid pressing from both sides bad tooth line.
Rotating spanner during use (11), by spanner seat (8) and cam ring (4) roller (6) is rolled in the track of cam ring (4), when the relative radial position of roller (6) is dwindled, bolt is clamped and can begins to screw in or withdraw from that this structure can reach dress and the purpose of tearing two functions open along contrary two-way rotating spanner (11).
Specification according to stud changes, and can design the block structure of corresponding cam ring (4), roller folder (5) and roller (6), and transposing gets final product when needing.
Stud series mounting or dismounting tools according to the utility model design, utilize the rolling of roller in inner cam track to make its relative radial position dwindle the polished rod position of clamping stud and clamp and install and remove bolt, this is simple in structure, mounting or dismounting are convenient, efficient is high, versatility is good, is fit to the mounting or dismounting of all size bolt.
Claims (2)
1, a kind of stud series mounting or dismounting tools, comprise spanner (11), spanner seat (8), limited post (9), overcoat (7) and steel ball (3), it is characterized in that being equipped with in the spanner seat (8) cam ring (4), steel ball (3) in spanner seat (8) and cam ring (4) mating surface is arranged in the through hole of spanner seat (8) radial equipartition and the steel ball nest of cam ring (4) radial equipartition, adorning the roller folder (5) of the axial dovetail groove that has radial equipartition in the cam ring (4), roller (6) is positioned at the dovetail groove of roller folder (5).
2, stud as claimed in claim 1 series mounting or dismounting tools is characterized in that also being equipped with in the cam ring (4) and prevents that the hole of scurrying on the roller folder (5) is with back-up ring (2).
