Abstract
The utility model relates to a tool to flare the metal thin wall annular port and is used with hand-held, electric or pneumatic tool which can provide rotating power. The tool includes a drawbar which can clamp the rotatable drawbar and a movable locating cylinder; the main body of the drawbar comprises a working head, a guide rod and a tail rod. The flaring tool is small in volume, light in weight and convenient use and can meet the precision processing on the thin wall annular port.
Description
Technical field
The utility model relates to a kind of instrument that the metal thin-wall annular port is carried out enlarging processing, is used by manual, the electronic or pneumatic handheld tool clamping that rotary power can be provided.
Background technology
At present, known flaring tool all is at bigbore mouth of pipe enlarging, is mainly used in the connection of pipe, and its precision requirement is not high, and the device of its enlarging and technology can not adapt to the enlarging to accurate thin-walled ring.In the assembling of aerospace field and some precision components, the enlarging of small-bore thin-walled ring installed be one technical barrier to be solved is arranged.A kind of flaring tool at installation quick-release lock ring in the aircraft manufacturing process produced in USA is present seen state-of-the-art accurate flaring tool basically, this instrument is a monolithic construction, contain the tool body of deciding square pneumtic impact wrench and enlarging moulding that power is provided, body is provided with working head, working head is advanced by the pneumtic impact wrench driven rotary, extend a bow arm configuration in addition on the body, the head of bow arm is provided with the corresponding enlarging working head of keeper, plays load and positioning action.Find this instrument in the use because deadweight and volume are bigger, have the degree of depth of bow arm to limit again, working head lacks guiding, and the location is inaccurate, can not satisfy the requirement of machining accuracy, and requirement must be opened wide and must be in problems such as the edge of workpiece installations to processing environment.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, provides a kind of volume little in light weight, easy to use, can satisfy the accurate enlarging processing to the thin-walled ring.
The application's technical scheme is as follows: but the pull bar of a clamping rotation and the positioning tube of an activity, the main body of pull bar is a working head that carries out spinning enlarging moulding, the shape of working head is mated with the target shape of final enlarging, the front central of working head extends to guide rod, the center, rear portion of working head extends to the foot piece that can grip, the endoporus of positioning tube is movable to be socketed on the preceding guide rod of working head, can will treat that the enlarging target workpiece is positioned on the front end guide rod of working head.
The front end of described positioning tube have can with the positioning boss of target workpiece coupling.
Guide rod has external screw thread before the described working head, and the smooth slightly larger in diameter of positioning tube endoporus of coupling is in leading shank diameter, and other has a setscrew nut spinning before screw-like on the guide rod.
Guide rod has external screw thread before the described working head, and the positioning tube endoporus of coupling also has the internal thread of coupling.
Before the described working head guide rod be one smooth cylindric, the positioning tube endoporus of coupling is smooth, slightly larger in diameter is in preceding guide rod.

Fig. 4 is the flaring tool overall structure that target workpiece is housed
Among the figure, guide rod, 5 activity orientation tubes, 6 setscrew nuts, 7 positioning tube endoporus, 8 positioning boss, 9 workpiece thin-walled rings, 10 target workpiece, 11 prefabricated horn mouths, 12 Assembly parts before 1 foot piece, 2 working heads, the 3 working head precentrums, 4.
The embodiment explanation
As shown in the figure, but this precision flaring tool is the Tiebar structure of a clamping rotation, the main body of pull bar is the working head 2 of a band precentrum 3, the cone shape of precentrum 3 is complementary with the target shape of final enlarging, the center of the precentrum 3 of working head extends to guide rod 4, on the outboard end of guide rod external screw thread is arranged, the center, rear portion of working head extends to the foot piece 1 that can grip, the external form of foot piece 1 is the rib shape preferably, so that it is supporting with clamping device, other has a positioning tube 5 movable being socketed on the guide rod 4, the target workpiece 10 for the treatment of enlarging is positioned on the guide rod 4 of working head, and the front end of positioning tube 5 also has the positioning boss 8 that is complementary with target workpiece.The endoporus 7 of the positioning tube that embodiment provides is a bright and clean hole, during use, with positioning tube target workpiece is located, other has a setscrew nut 6 to be screwed onto on the outside screw of preceding guide rod, this setscrew nut can be fixed with external force, during enlarging, external force clamping foot piece advances working head and the rotation of preceding guide rod thereof.Fig. 4 reflection be real work the time target workpiece and flaring tool correlation, target workpiece 10 and part 12 are assembled, thin-walled ring 9 is carried out enlarging and is fitted on the prefabricated horn mouth 11 of part 12, part 12 and target workpiece 10 are enclosed within respectively on the preceding guide rod 4 of flaring tool, again positioning tube 5 is socketed on the guide rod 4, positioning boss 8 with positioning tube 5 front ends snaps in the uropore of target workpiece 10, target workpiece 10 is embedded in the pre-assembled hole of part 12, external force clamping foot piece 1 advances working head 2 rotations, positioning tube and clamp nut assurance target workpiece and part are relatively stable, the precentrum 3 rotation extruding thin-walled rings 9 of working head, with its enlarging until reaching dbjective state.
This flaring tool is simple in structure, and accurate positioning is used flexibly, can satisfy the various accurate enlarging function to the metal thin-wall ring.
Claims (3)
1, a kind of accurate flaring tool, it is characterized in that but this instrument contains pull bar and an activity orientation tube of a clamping rotation, the main body of pull bar is the working head of a rotary press modelling, the front portion of this working head extends to guide rod, the rear portion of working head extends to foot piece, and positioning tube is movable to be socketed on the preceding guide rod of working head.
2, flaring tool as claimed in claim 1 is characterized in that described positioning tube front end has positioning boss.
3, flaring tool as claimed in claim 1 or 2 is characterized in that the preceding guide rod of described working head has external screw thread.
