Background technology
Excavator is a kind ofly with scraper bowl, to excavate higher or lower than the material that holds machine side the haulage vehicle or unload the earthmoving machinery to rickyard of packing into, and according to the walking manner difference, excavator can be divided into crawler-mounted excavator and wheel excavator.The crawler belt of crawler-mounted excavator includes the interconnective chain sheet of plural piece, and each chain sheet has two to connect circular hole along its length, and one of them connects circular hole and has small one and large one two kinds of different apertures along its axial direction, and this circular hole also is referred to as shoulder hole.Be equivalent to the hole that the chain sheet comprises three different pore size values,, in the action of the bore hole in chain sheet aperture, need divide at present and do single hole boring operation for three times.In described chain sheet bore hole, there is to higher specification requirement in each aperture, divides at present single hole boring mode three times, not only dismounting is loaded down with trivial details, and production efficiency is low, and high to the dismounting positioning requirements, has that production cost is high, a low problem of finished product rate.
The utility model content
The purpose of this utility model is to provide a kind of bore hole new device of crawler-mounted excavator chain sheet, takes diplopore boring simultaneously mode, has the advantages such as boring efficiency is high, assembly performance is excellent, production cost is low.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of bore hole new device of crawler-mounted excavator chain sheet, have boring mechanism, and this boring mechanism is provided with two boring knife bars of horizontal Tile, and these two boring knife bar the place aheads are provided with the detent mechanism for chain sheet horizontal type location.
Described detent mechanism comprises positioning seat body and hold out against assembly, and on this positioning seat body, the anterior position of corresponding boring knife bar is provided with station platform; The described assembly that holds out against has movable axis, the middle part of this movable axis is movably articulated on the articulated section of described positioning seat body, the piston rod of the rearward end of described movable axis and a cylinder is movably hinged, this piston rod is made the above-below direction telescopic movable, and the leading section of described movable axis is equipped with the head that holds out against that the head that is positioned at described station platform top arranges down.
Convex with two locating dowels for two perforate location on the chain sheet on described station platform.
After adopting such scheme, this Novel photo is for the beneficial effect of prior art: during work, by the chain sheet, suitably be positioned on detent mechanism, two two boring knife bars that connect circular hole and boring mechanism of chain sheet coaxially are oppositely arranged, boring mechanism operation afterwards, drive the suitable feed motion of two boring knife bars and rotation main motion, three different pore size single holes with this to two connection circular holes carry out boring operation simultaneously, after boring is complete, two boring knife bars stop the rotation and do setback, repeatedly carry out thus.Described diplopore (three single holes) the boring simultaneously mode of taking, have the advantages such as boring efficiency is high, assembly performance is excellent, production cost is low compared to existing technology.

The specific embodiment
Below in conjunction with the drawings and specific embodiments to originally being described in further detail.
This novel bore hole new device that relates to a kind of crawler-mounted excavator chain sheet, as shown in Figure 1-2, comprise boring mechanism 1 and detent mechanism.
Boring mechanism 1 is provided with two boring knife bars 11 of horizontal Tile, and under controlling in boring mechanism 1 internal drive unit, these two boring knife bars 11 can or retreat along level to feeding, and can carry out spinning motion.Described detent mechanism, for locate chain sheet 5, makes the dead ahead of chain sheet 5 accumbency at two boring knife bars 11.
The structure of chain sheet 5 as shown in Figure 3, offers two and connects circular hole 51 on it, these two of connecting in circular hole 51 connect circular hole and have small one and large one two kinds of different apertures along its axial direction, also claim shoulder hole.Two connect three single holes that circular hole 51 has different pore size.In two boring knife bars 11, there is dividing of thickness at least one its bar footpath, with described shoulder hole, is complementary corresponding.Two connect 51 of circular holes also offers a big hole, on a connection sidewall of this big hole, offers two perforates 52.
As a preferred embodiment of detent mechanism, as shown in Figure 1, comprise positioning seat body 2 and be arranged on the station platform 3 on this positioning seat body 2 and hold out against assembly 4.Station platform 3 correspondences are positioned at the position, dead ahead of boring knife bar 11, for placing for 5 accumbency of chain sheet.Preferably, convex with two locating dowels 31 on station platform 3,5 accumbency of chain sheet simultaneously, these two locating dowels, 31 correspondences plant chain sheet 5 two perforates 52 in, be beneficial to thus chain sheet 5 and make zero deflection ground strong fix, and be beneficial to and hold out against assembly 4 its enforcement is held out against to effect.Certainly detent mechanism is not limited only to described preferred embodiment, and it can also take to hold or method of clamping is realized the positioning action of chain sheet 5.
The described assembly 4 that holds out against is for holding out against from top to bottom the chain sheet 5 of accumbency on station platform 3.Holding out against assembly 4 can have numerous embodiments, and the cylinder for example arranged down for piston rod down holds out against chain sheet 5 by piston rod end.This case provides another preferred embodiment, holding out against assembly 4 comprises movable axis 41, cylinder 42 and holds out against 43, the middle part of movable axis 41 is movably articulated on the articulated section of positioning seat body 2, the piston rod of the rearward end of movable axis 42 and cylinder 42 is movably hinged, the piston rod of cylinder 42 is made the above-below direction telescopic movable, hold out against 43 be positioned at station platform 3 directly over, its with head down mode be arranged on the leading section of movable axis 41.
During work, at first by perforate 52 and locating dowel 31, coordinate stably accumbency of chain sheet 5 on station platform 3, cylinder 42 actions afterwards, its piston rod drives movable axis 41 rearward end and up moves, it is fulcrum that movable axis 41 be take its middle part pin joint, and the leading section of movable axis 41 moves down, thereby drive, holds out against 43 and tilts down, finally just hold on chain sheet 5 (as shown in Figure 2), realize thus the reliable firm positioning action again of chain sheet 5.Behind location, two of chain sheet 5 two boring knife bars 11 that connect circular hole 51 and boring mechanism 1 coaxially are oppositely arranged, boring mechanism 1 operation afterwards, drive the suitable feed motion of two boring knife bars 11 and rotation main motion, three different pore size single holes with this to two connection circular holes 51 carry out boring operation simultaneously, after boring is complete, two boring knife bars 11 stop the rotation and do setback, repeatedly carry out thus.
The foregoing is only this novel preferred embodiment, all equalizations of doing with this novel claim scope change and modify, and all should belong to the scope of this novel claim.
