The utility model has a central fixing mechanism and a bracket, and the central fixing mechanism and the bracket are used to ensure sufficient rigidity. The cutting and processing device has a convenient manual axial direction feed mechanism and an automatic, semiautomatic, or manually knocking action radical feed mechanism. The utility model has the advantages of compact structure, convenient installation and disassembly, stable operation, and high reliability. The smoothness degree of the processed surface reaches *4.
Description
A kind of metal cutting processing unit (plant) is used for the back processing of on-the-spot assembling location or repairs flange sealing surface.
In industrial production flange sealing surface often owing to the corrosion and other reason damage, its sealing surface performance is damaged, for small-sized flange generally is to change or processing reparation on lathe, but for large-scale flange, the above-mentioned way of the flange that can not take off is just unworkable, can only process at the scene or repair, prior art has been made some equipment that can carry out on-the-spot processing or repair flange.But all huger, use inconvenience; The installation that has fixed mechanism be only limited to certain particular device can not be general.
Purpose of the present invention just is to provide a kind of any flange all is convenient to the on-the-spot cutting apparatus that installs and fixes, and this device has the convenient delivering gear that is suitable for.
The architectural feature of this utility model:
Adopting common motor or air motor is power.Drive a worm screw ［ 1 ］ and rotate, rotate thereby drive worm gear ［ 2 ］, this worm gear ［ 2 ］ is fitted together with moving cover ［ 8 ］, carriage saddle ［ 9 ］ is installed in moving putting, therefore, worm gear ［ 2 ］ just drives carriage saddle ［ 9 ］ and rotates together, and knife rest ［ 15 ］ is loaded onto cutting tool can carry out machining.
Centre at the processing end of this cutting apparatus is provided with tensioner type stationary positioned mechanism.This mechanism is by mandrel ［ 4 ］ mother ［ 13 ］ of rising, fixed cover formations such as ［ 11 ］; Mandrel ［ 4 ］ is the centre strut of this utility model, tensioner head ［ 12 ］ (see figure 2) that an opening is arranged in its lower end, fixed cover ［ 11 ］ is by 4 identical fixed blocks, connect the internal diameter little 0.2-0.5mm of the outside dimension of garden this cylinder of cylindrical shell (see figure 3) that forms through 2 garden shape cards made from spring steel wire ［ 14 ］ than processed flange, so that this stationary positioned mechanism inserts in the flange hole easily, then by on carry logical heart nut ［ 3 ］, make on the mother of rising ［ 3 ］ and move, by female effect of rising that tensioner head ［ 12 ］ support is big, thus fixed cover ［ 11 ］ also is stretched.Till the big endoporus to its external diameter and flange that rises closely cooperates, make the convenient center of firmly being fixed in machined surface of whole cutting apparatus by this stationary positioned mechanism, be convenient to cutting operation, in order to make whole cutting mechanism more firm, utilize the bolt of flange that cover ［ 22 ］ and support ［ 7 ］ are set again, this support ［ 7 ］ utilizes the bolt of flange to take root, and reaches the upper end of this mechanism, the upper end is embraced, constituted a kind of frame-type fixed mount that is applicable to that the processing flange is used.
In order to realize axial feed, be provided with the axial feed device.Constitute by spiral ［ 5 ］ and sliding sleeve ［ 6 ］; Sliding sleeve ［ 6 ］ be kink on mandrel ［ 4 ］, this sliding sleeve upper end links with spiral ［ 5 ］, lower end and carriage saddle ［ 9 ］ link, and therefore, when spiral ［ 5 ］ is tightened (or moving back), can drive carriage saddle ［ 9 ］ feed (or withdrawing).
The radially delivering gear of this utility model is by leading screw ［ 20 ］, driving lever ［ 17 ］, ratchet ［ 19 ］ and ratchet formations such as ［ 18 ］.Leading screw ［ 20 ］ is fixed on the carriage saddle ［ 9 ］, the female thread that leading screw ［ 20 ］ and knife rest ［ 15 ］ are had, the outer rim of ratchet has ratchet, ratchet ［ 18 ］ and driving lever ［ 17 ］ all use same fixed axis ［ 16 ］ to be installed on the carriage saddle ［ 9 ］, and the two all can rotate around axle ［ 16 ］.
Radially the delivering gear course of work is as follows:
In this topping machanism rotation process, establish special block or manually knock driving lever ［ 17 ］, (shown in Fig. 4 arrow) makes driving lever ［ 17 ］ swing around axle ［ 16 ］.Drive angle of ratchet ［ 18 ］ swing, thereby stir ratchet ［ 9 ］ and rotate a ratchet, reset under the effect of spring ［ 21 ］ then, leading screw rotates with ratchet, and knife rest ［ 15 ］ is contained on the screw mandrel by screw thread, when screw mandrel rotates, knife rest promptly moves along the axis direction of screw mandrel, thereby realizes feed (or withdrawing) operation, suitably designs the thread pitch of leading screw ［ 20 ］, can guarantee the size of each depth of cut, the design depth of cut of this mechanism is 0.12mm.
Above-mentioned each parts are all manufactured with steel.
It is convenient that the utility model is installed the location, compact conformation, and integral rigidity is good, and running is steady, easy disassembling, it not only is applicable to the processing of flange sealing surface, all can use for porose any equipment in the middle of other, says to have versatility in a sense.Cutting face fineness reaches on probation
4, the flange face reparation of Dg100 is after 510 ℃-868 ℃, operating pressure 3-3, and the 5MPa test is not leaked.
Exemplary embodiments of the present utility model, shown in Figure of description:
Fig. 1 is a structure chart of the present utility model.Fig. 2 is the tensioner head of mandrel, and Fig. 3 is the structure chart of fixed cover.Fig. 4 is the schematic diagram of delivering gear radially.Fig. 5 is that knife rest reaches the radially structure chart of delivering gear.
Last figure draws according to a most preferred embodiment fully, and power source adopts the motor of 0.8Kw, and processed flange ［ 10 ］ specification is Dg100mm.The overall size of mechanism is high 588mm, garden body diameter 400mm.Other as described above.
