Description
Technical field
The utility model belongs to the machine tool component technical field, relates to a kind of positioning tool, particularly a kind of rocking arm positioning tool.
Background technology
Rocking arm is the part of valve actuating mechanism in the engine, and its function is valve to be passed in the motion that push rod and cam transmit make its unlatching.Rocking arm is a double-arm lever, and take rocker arm shaft as fulcrum, two arms are not isometric.The galianconism end is processed with screwed hole, is used for being screwed into valve adjusting screw.Long arm end is processed into arc surface, is the working face that promotes valve.
Rocking arm is adding man-hour, need to be at the boring of the two ends of this rocking arm and end face milling, but because of the rocking arm profile extremely irregular, the clamping rocking arm is very hard, needs many people to cooperate just and can finish, but also can not guarantee to make rocking arm to be located fully, the situation that rocking arm rocks occurs when boring often, even rocking arm can deviate from from clamping, rocking arm and drill bit bumped cause the rocking arm surface to scratch, and also can sever drill bit.Usual way is that clamping process is very consuming time by screw pressing plate clamping at present, causes the clamping time also longer process time than drilling, has had a strong impact on production efficiency.In addition, in boring procedure, because the clamping reason causes bits bad, affected for the second time clamping positioning accuracy, be not suitable for producing in enormous quantities.In sum, at present for the clamping of the rocking arm of this profile irregular, therefore can not make the rocking arm location fully, existing crudy can not guarantee, the shortcoming that clamping overlong time, production efficiency are very low.
For this situation, people have recognized deficiency, and improve, a kind of drilling clamp of rocker arm [application number: 201120096422.5 that openly proposes such as Chinese patent literature; Granted publication number: CN202015960U], comprise die holder, and be positioned at base and cope match-plate pattern on the die holder, cope match-plate pattern is positioned at base top and corresponding with base, and base is fixed in a side of die holder, and the opposite side of described die holder has a hole, the hole is built-in with a helical gear, have a vertical fluting on the die holder, be inserted with a helical rack that matches with helical gear in the fluting, the top of helical rack is fixedly connected on cope match-plate pattern; A helical gear end is connected with swing handle.Thereby the movement of rotating helical gear drive cope match-plate pattern by swing handle reaches being installed in the clamping of the workpiece on the base, but because rocking arm is irregular surface, therefore it is not firm to shine into easily clamping when cope match-plate pattern clamps workpiece, rocks the deviation of shining into processing thereby can produce when boring; During simultaneously owing to this clamp workpiece, can only carry out Drilling operation to workpiece, can not carry out end face milling to workpiece, cause inconvenience to use.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, proposed a kind of locate reliable can be to hole rocking arm positioning tool with end face milling of workpiece firmly and during clamping one time.
The purpose of this utility model can realize by following technical proposal: a kind of rocking arm positioning tool, comprise base, described base is provided with riser, it is characterized in that, the sidepiece of described riser is equipped with tubular internal expanding mandrel, one end of described internal expanding mandrel protrudes from the sidepiece of described riser, it is circumferentially fixing that described internal expanding mandrel inside is equipped with pull bar and described pull bar and described internal expanding mandrel, one end of described pull bar has taper seat one, one end of described internal expanding mandrel has the taper seat two that is complementary with taper seat one, the other end of described pull bar also is provided with and can drives the axially movable driving mechanism of the relatively described internal expanding mandrel of described pull bar, the sidepiece of described riser also be provided with the both ends of protruding and supplying respectively workpiece against butting section one and butting section two, described butting section one is provided with the end that can promote to be resisted against the workpiece on the butting section one makes the other end of workpiece be resisted against pushing mechanism on the butting section two.
In use, the mesopore of automobile rocking arm is nested on the internal expanding mandrel, and the one end is resisted against on the butting section one, driving the relative internal expanding mandrel of pull bar by driving mechanism again moves axially, extruding cooperation by taper seat is opened with the automobile rocker arm shaft to being positioned on the riser end of internal expanding mandrel, one end of pushing mechanism promotion this moment workpiece abuts against the other end of workpiece and prevents on the butting section two that workpiece from rotating relative to riser, thereby reach workpiece is positioned on the riser, can carry out to rocking arm the processing of end face milling and boring, relatively common anchor clamps, need to carry out two clampings, this rocking arm positioning tool can reach end face milling and boring by one-time positioning, has the machining accuracy height, easy to operate advantage.After processing, can drive pull bar by driving mechanism and reset, the end of internal expanding mandrel resets workpiece is unclamped at this moment, and pushing mechanism resets simultaneously, and workpiece is unclamped, and takes off from riser to get final product.
In above-mentioned rocking arm positioning tool, the sidewall of described pull bar is provided with strip groove, is equipped with screw on the described riser, and the inner of described screw is positioned at described strip groove.The inner of screw is positioned at strip groove, limited the displacement of moving of pull bar relative to the internal expanding mandrel, prevent from drawing the internal expanding mandrel to be subject to excessive stress and damage, improved service life, prevent simultaneously that pull bar breaks away from the internal expanding mandrel and the use inconvenience that causes.
In above-mentioned rocking arm positioning tool, described driving mechanism is the latch segment that circumferentially rotates with described internal expanding mandrel axial restraint, and described latch segment links to each other with the other end screw thread of described pull bar, is fixed with handle on the described latch segment.The relative internal expanding mandrel of latch segment axial restraint axial rotation when turning handle drives the latch segment rotation, makes pull bar move relative to described internal expanding mandrel.
