Abstract
The utility model relates to an articulated wrench for a cylindrical threaded part. The articulated wrench is characterized by comprising an annular fixing strap and a flexible gasket in the annular fixing strap, wherein a left fork head rod and a right fork head rod are respectively connected to two tail-ends of the annular fixing strap; the other end of the right fork head rod is sleeved on the left fork head rod; and a gripping rod is arranged at the rear part of the left fork head rod. The articulated wrench provided by the utility model has the advantages of simple structure, portability and adjustability, and almost causes no damage to the part.
Description
Technical field
The utility model belongs to and relates to a kind of cylinder screw thread handler.Mainly be applicable to the installation and removal of thin walled cylindrical part.
Background technology
Column type is a Machine Design conventional design shape, and internal thread is adopted in the inside of cylindrical part, and common parts (such as double-screw bolt) is designed with external screw thread, above-mentioned both with being threaded, thereby the mount process of completion common parts and cylindrical part.
In the threaded engagement assembling process of common parts and cylindrical part, need use assembly tool-spanner, common wrench generally is that design spanner card ends structure on cylindrical part, thereby makes common wrench can block cylindrical part, carry-over moment smoothly.
Miniature parts design time ratio is easier to, but large and medium-sized part, particularly punched thin-wall cylindrical component; Such as diameter is 150mm; Under the situation of thin and thick less than 0.5mm, its card ends structure, generally is to adopt welding or riveted structure to realize; Ancillary equipment is riveted or is welded in the cylindrical component, artificially do card release again and end structure.
Said method not only volume weight is bigger, and influences part strength (welding burn and riveted holes structure).For example heavy motor truck is with the dismounting of drying.
Summary of the invention
The purpose of the utility model is: provide a kind of simple to operate, easy to carry, do not damage assembly parts, the cylindrical part screw thread that can assemble fast and dismantle with hinged spanner to remedy the deficiency of prior art.
The technical scheme of the utility model is: the cylindrical part screw thread is used hinged spanner; It is characterized in that: comprise annular fixed band and inner flexible liner thereof; Two ends at annular fixed band have been connected with left forked end lever and right forked end lever respectively; The other end of right forked end lever is enclosed within on the left forked end lever, and the grip bar is arranged behind the left forked end lever.
Optimize: right forked end lever and left forked end lever connecting portion are provided with adjusting device.
Optimize: adjusting device is the pair of adjustment nut.
The utility model has the advantages that: the utility model is a kind of utilize articulated structure interlocking principle and tribology principle design; The steel band circle that a disconnection is arranged; The bonding thicker rubber skin of inner face (requiring can change into more greatly the winding cotton) like torsion, the column part of two welding band cylindrical hole is fixed two wishbones and column part with threaded straight pin; Make between part and can rotate each other, but can not move.Interconnect with traveller between the wishbone, utilize nut check, the screw-threaded coupling position can be regulated, and wherein a wishbone design is longer, and is processed into screw thread, and the bar of shaking hands is housed on the screw thread.These article are simple in structure, and are easy to carry, have modulability, and part is not had damage basically.

The specific embodiment
Embodiment:
1 is the rubber skin among the figure, is bonded in annular fixedly on the steel band 2 (bigger like the torsion requirement, can change cotton into, be wrapped on the steel band).The annular fixedly two ends end of steel band 2 is welded with hollow circuit cylinder 9 respectively.Left side forked end lever 4 and right forked end lever 7 pass behind the circular hole of hollow circuit cylinder 9 fixing respectively through screw thread lock pin 3, jack panel 8 is fixing with being equipped with.Right forked end lever 7 is enclosed within on the left forked end lever 4, and fixing with two adjusting nuts 5, adjusting nut 5 positions can free adjustment.Grip bar 6 is threaded with left forked end lever 4 usefulness, is used for convenient assurance.
In use.Annular fixedly steel band 2 diameters generally according to the cylindrical size design of Assembly part.Need fix with the part that the cylinder of needs rotation cooperates: entangle cylinder with the radial type spanner, use for the first time in this way, can regulate two adjusting nuts 5, it is tight to make the steel band diameter be fit to cylinder reserve.The grip that turns clockwise bar 6; Utilize hinged lock function and frictional force just can drive the cylinder rotation, because articulated structure has self-locking action, the moment on the grip bar is big more; The moment of friction that produces on steel band 2 and the rubber skin 1 is just big more, utilizes this moment of friction just can cylinder be screwed.Not enough like the moment on the grip bar, can also increase sleeve, the lengthening arm of force, the turning moment that this radial type spanner can produce in theory depends on the intensity of each part.Screw off cylinder like need,, rotate counterclockwise spanner and can screw off part being enclosed within on the cylinder after the upset of radial type spanner.
Claims (3)
1. the cylindrical part screw thread is used hinged spanner; It is characterized in that: comprise annular fixed band and inner flexible liner thereof; Two ends at annular fixed band have been connected with left forked end lever and right forked end lever respectively, and the other end of right forked end lever is enclosed within on the left forked end lever, and the grip bar is arranged behind the left forked end lever.
2. use hinged spanner according to right 1 described cylindrical part screw thread, it is characterized in that: right forked end lever and left forked end lever connecting portion are provided with adjusting device.
3. use hinged spanner according to right 2 described cylindrical part screw threads, it is characterized in that: adjusting device is the pair of adjustment nut.
