The flexible connection of edge follow rest, and fixed pin longitudinal center line is overlapped with 25 longitudinal center line of hook bolt pin hole, to guarantee to use
When can quickly determine center, accurate positioning, circular arc cooperation frame can cooperate with the draft lugs of hook bolt.
There are many set-up modes of the structure of draft lugs follow rest, for example, the lateral linear guide, draft lugs with
There are two row frame, draft lugs centring means and molding bistrique are all provided with, two lateral linear guides are separately positioned on table on pedestal
Face two sides, two draft lugs follow rests are flexibly connected with two lateral linear guides respectively, two draft lugs centring means
It being connect respectively with two draft lugs follow rests, two molding bistriques are connect with two draft lugs centring means respectively, and two
Hook bolt positioning seat is connected respectively close to two draft lugs follow rests, is provided with draft lugs on two draft lugs follow rests
Internal point and draft lugs retinue slot；Such as a draft lugs follow rest include bottom plate 20 and positioned at bottom plate two sides and bottom plate
Two vertical plates 21 being linked together, bottom base plate open up relief hole, the screw rod for avoiding screw riser, and other component is set
Set becomes being arranged on vertical plate referring to aforesaid way from being arranged on draft lugs follow rest.
There are many set-up modes of hook bolt clamping device, for example including fixed block 22, gripping block 23 and lock-screw 24, leads to
The connection that is fixedly connected with realization hook bolt clamping device of the fixed block with planker is crossed, gripping block passes through and lock-screw connects with fixed block
It connects, is determined hook bolt by screwing lock-screw after hook bolt positioning seat positions on curved surface accordingly when hook bolt tractional surface 26 sticks on
Position clamps.
Application method of the present invention:
Step 1: hook bolt is mounted on draft lugs follow rest, and the tractional surface 26 of hook bolt is reclined hook bolt positioning seat 4 accordingly
Position, pushing down hook bolt with hook bolt clamping device 5 makes it be fixedly clamped.
Step 2: two draft lugs centring means are separately mounted on draft lugs follow rest.
Step 3: the height of vertical lift platform is adjusted by screw riser 10, planker is adjusted by carriage feeder 2
Lengthwise position, the lateral position that draft lugs follow rest is adjusted by follow rest feed arrangement 11.
Step 4: being that the center of circle rotates two draft lugs centring means 8 respectively with draft lugs internal point 15, if traction
The circular arc cooperation frame 19 of flange centring means can recline draft lugs 27 and lower draft lugs 28 and rotation process in hook bolt just
Middle no card resistance, then without using molding bistrique carry out polishing processing；If the circular arc cooperation frame and hook of draft lugs centring means
Tongue draft lugs cambered surface interferes, the draft lugs centring means is entered from smooth rotation reclines with draft lugs, this
Need to occur the phenomenon hook bolt draft lugs process, by corresponding draft lugs centring means take out, by it is electronic at
The directive wheel of type bistrique 29 sticks in the retinue guide groove of draft lugs 9 corresponding sides of retinue, turns on the switch, will be high-speed rotating
Bistrique is moved along retinue guide groove, completes the processing of hook bolt side draft lugs.
Step 5: after the completion of the draft lugs grinding of hook bolt side, again by corresponding one group of draft lugs centring means
It is secondary to be mounted in the corresponding draft lugs internal point of draft lugs follow rest, rotate draft lugs centring means, such as and hook bolt
Draft lugs cambered surface abutting contact well then processes qualification, thus ensure that draft lugs in hook bolt, lower draft lugs it is concentric
The requirement of position degree.Then show that forming bistrique abrasion transfinites, and more renews bistrique, reconditioning is until qualified if there is interference.
Step 6: unclamping hook bolt clamping device, takes out hook bolt.
Those skilled in the art should know the protection scheme of the present invention is not limited only to the above embodiments, can also be
Various permutation and combination and transformation are carried out on the basis of above-described embodiment, on the premise of without prejudice to spirit of the invention, to the present invention
The various transformation carried out are fallen within the scope of protection of the present invention.
