Description
Technical field
The utility model relates to a kind of standpipe of front fork staving press, is a kind of also equipment of reaming of holing on front fork that is used for.
Background technology
Usually have front fork on the vehicle frame of motorcycle or bicycle, two support jibs of front fork are in front-wheel rotating shaft place of car body, are positioned on the joint portion of two front fork support arm junctions to have through hole, and the vehicle frame that the car stem is divided is plugged in the through hole and strong bonded.Front fork is made by two pipe fittings are bent and are welded on the short tube in the conventional art, advantage such as big, in light weight and easy to process more and more is subjected to producer's favor and the aluminum current alloy is with its intensity, the aluminium alloy front fork of making by casting can well satisfy the parameters requirement of front fork, yet the appearance of new technology has but changed original processing mode, because the joint portion of casting front fork does not but have through hole, this just need hole and bore hole to the front fork of casting, so that it can assemble with miscellaneous part.
Summary of the invention
The purpose of this utility model provides a kind of standpipe of front fork staving press, holes and reaming in its joint portion to front fork.
The technical solution of the utility model is: a kind of standpipe of front fork staving press, it comprises frame, be fixedly set in locating piece on the described frame, be arranged on the pressing plate of the top of described locating piece movably, have locating hole on the described pressing plate, also turn on the described frame and be provided with cutter, and described cutter can be connected on the frame of described pressing plate top up or down.
Have the through hole that extends along the plumb line direction on the described locating piece, be inserted with backstay in the described through hole, the axial line of described backstay is positioned on the extended line of revolution axial line of described cutter.
Be positioned on the frame of described locating piece below and also be provided with the hook holder movably, flexibly be provided with the hook fixed axis on the described hook holder.
The utility model compared with prior art, have following advantage: the lower end of front fork to be processed is fixed on the hook holder, top then is pressed on the locating piece by pressing plate, backstay upwards can accurately be located the position of front fork to be processed, cutter moves down and front fork is holed or bore hole or fraising, the utility model can be realized quick clamping, and accurately locatees the reaming position, its working (machining) efficiency height.

The specific embodiment
Referring to accompanying drawing 1 to accompanying drawing 3, a kind of standpipe of front fork staving press, it comprises frame 1, be fixedly set in the locating piece 4 on the described frame 1, be arranged on movably the top of described locating piece 4 pressing plate 8 (described in this specification " on ", D score position relation is corresponding with the relation of upper-lower position shown in the accompanying drawing 1), the top that is positioned at described pressing plate 8 on the described frame 1 also is set with guide rail 12, slidely connect motor 11 on the guide rail 12 mutually, the rotor of motor 11 is connected with cutter 10 mutually, front fork 17 to be processed is placed on the locating piece 4, therefore the top of locating piece 4 has one section shoulder that broadens, and can make front fork 17 be able to firmly frame on described locating piece 4.
Be positioned on the frame 1 of described locating piece 4 belows and also be provided with hook holder 2 movably, flexibly be provided with hook fixed axis 5 on the described hook holder 2, the lower end of two front fork support arms 3 is processed with slot in advance, described hook fixed axis 5 is inserted in this slot, and the lower end of front fork 17 is fixed on the hook holder 2.Also have the gathering sill 16 that extends along vertical on the frame 1, and hook holder 2 is locked on the gathering sill 16 by screw bolt and nut, when processing the front fork 17 of different size, not only the height of hook fixed axis 5 can flexibly be regulated, and can unclamp nut and make hook holder 2 rise or to descend along gathering sill 16.
For preventing reaming position deviation precalculated position, be processed with datum hole in the lower surface of the joint portion 19 of front fork 17 in advance, can find bore position accurately and locate front fork 17 by this datum hole.
Have the through hole that extends along vertical guide on the described locating piece 4, be inserted with backstay 14 in the described through hole, the axial line of described backstay 14 is positioned on the extended line of revolution axial line of described cutter 10, and the upper end of backstay 14 has the end that attenuates; Also be set with first oil cylinder, 6, the first oil cylinders 6 on the frame 1 of the below of backstay 14 and have first piston bar 7, described first piston bar 7 can be with backstay 14 jack-up, so it can be inserted in and determines boring or reaming position in the datum hole.
Also be set with second oil cylinder 15 on the described frame 1, described second oil cylinder 15 has rotatable 90 ° second piston rod, described pressing plate 8 is fixedly connected on second piston rod, drives second oil cylinder, the 15 controlled plates 8 of neutralizing its rotation also just is pressed on the joint portion of front fork 17 downwards.Therefore, front fork 17 is fixed, and the revolution axial line of cutter 10 just is positioned at the reaming position.
Also have locating hole 9 on the pressing plate 8, described cutter 10 can be drill bit or boring cutter or reamer, rotates under the drive of motor 11 and moves downward, and reaming is carried out in joint portion 19.In the present embodiment, have boring and two stations of bore hole on the frame 1 simultaneously.
