Abstract
A hanger which is combined by car coupler and coupler knuckle, with a fixed wedge pin and a moving wedge pin installed on a frame-type framework. The hanger uses the car coupler and a round pinhole of the coupler knuckle as a location datum, and extends the location datum to processing machine; making use of the assembling hanger hoist the car coupler and the coupler knuckle to the machine tool, can make the car coupler and the coupler knuckle with different location of round pinhole, without considering the shape difference and the hole location difference of workpieces in processing, thus adjusting the knife precisely and without adjusting the knife repeatedly in the batch processing.
Description
Affiliated technical field
The utility model belongs to work piece holder, and specifically it is to be used for the machining tool special hanger that location hitch, hook tongue are used when processing hitch, hook tongue pin hole.
Background technology
Railway locomotive, vehicle are walked on railway, and the hook tongue of its hitch is used for guaranteeing its connection and passes on tractive force, in use because of stressed very conference causes very big wearing and tearing, needs often processing to repair, and its process is a reaming edge cover.The tool setting before but hitch and hook tongue are processed on lathe at present is that the shortcoming of visual tool setting is will expend for a long time by the visual tool setting of lathe worker, and the 6-8 that its tool setting time approximately is process time doubly belongs to no benchmark presetting cutter method.Often, make the working (machining) efficiency of machining tool can not get maximum performance because tool setting has slowly been incured loss through delay process time.Tracing it to its cause is, hitch and hook tongue itself are the blank workpiece, self no locating surface, and the pin hole position on each hitch and the hook tongue has nothing in common with each other, make workpiece of the every processing of work in-process all will adjust lathe No. one time,, increased adjustment lathe time and tool setting time continually a cutter.Solve the problem of hitch and hook tongue long processing time on lathe, then must solve hitch and the location benchmark problem of hook tongue on lathe, reduce the tool setting time.
Summary of the invention
In order to solve hitch and the hook tongue location benchmark problem on lathe.The utility model provides a kind of special combination suspender that is used for hitch and hook tongue, this suspender serves as the location benchmark with the pin hole of hitch and hook tongue self, and should locate benchmark and extend to machining tool, can solve hitch and the hook tongue location benchmark problem on machining tool easily.
The technical scheme that the utility model solution hitch and the location benchmark problem of hook tongue on lathe are taked is: the suspender of doing a kind of special use, the suspender framework is the closed-in construction of an opening, hoisting ring is installed on framework, end at the framework opening part is equipped with fixedly taper pin, the other end at the framework opening part is equipped with movable taper pin supporter, in the cavity of movable taper pin supporter, be equipped with the conical surface relative with the fixing taper pin conical surface and axis and the movable taper pin of fixed cone pin axis on same straight line, movable taper pin can move back and forth along axis, be connected with movable taper pin drive unit at movable taper pin supporter rear portion, movable taper pin drive unit divides manually, hydraulic pressure or pneumatic, the drive rod front portion of movable taper pin drive unit is connecting movable taper pin, drive rod rear portion at manual movable taper pin drive unit is equipped with the driving handwheel, and the drive rod of hydraulic pressure or pneumatic movable taper pin drive unit is by stretching out in the driving cylinder that is connected movable taper pin supporter rear portion.Fixedly taper pin is the identical supporting surface of shape of cross section with movable taper pin supporter outside, do two be used for support fixation taper pin and movable taper pin supporter external support plane the indent supporting surface and the supporter of certain distance separately arranged, supporter is installed on clamp body or the lathe, suspender is placed on the supporter, make that fixedly taper pin and movable taper pin supporter external support plane are done respectively on the indent supporting surface of two supporters, adjusting supporter makes fixed cone pin axis and movable taper pin axis be parallel to main-shaft axis, fixed support body.
Positioning principle of the present utility model is: with the pin hole of hitch and hook tongue self is the location benchmark, and uses suspender and should locate benchmark and extend to machining tool.Specifically, come crane hook and hook tongue with suspender, suspender is a hole for hoist with hitch and hook tongue pin hole on hitch and hook tongue, and suspender is located in hitch and hook tongue pin hole with the taper pin form, taper pin and the movable taper pin center of circle overlap with the center of circle of hitch and hook tongue two pin hole respectively because the taper pin effect makes fixedly (the theoretical coincidence), so, after suspender is located in hitch and hook tongue pin hole, hitch and hook tongue pin hole axis very near and be parallel to fixedly taper pin and movable taper pin axis place straight line.Suspender is connected hitch and the hook tongue has been placed on the inner concave supporter, and taper pin and movable taper pin support body supports face are seated in supporter two supporting surfaces respectively, because fixedly taper pin and movable taper pin axis place straight line parallel are in main-shaft axis, thus hitch and hook tongue pin hole axis very near and be parallel to main-shaft axis.At workpiece bottom gag jam-pack, workpiece pressing removes suspender, can process.Because the position of supporter on lathe is changeless, so the position of the pin hole of each workpiece on lathe also is changeless, therefore, only need when the processing subsequent workpiece, then not need tool setting, saved the tool setting time to a cutter when the processing unit one.
The utility model compared with prior art, suspender serves as the location benchmark with the pin hole of hitch and hook tongue self, and should locate benchmark and extended to machining tool, work in-process does not consider that the differences in shape of workpiece and hole potential difference are other to make different hitch in pin hole position and hook tongue owing to used special hanger, do not need tool setting, save the tool setting time, improved working (machining) efficiency.
