The specific embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
Shown in Fig. 2,3: the utility model mainly comprises base 2, location, small end hole expansion mechanism 1, expansion set ejecting mechanism 3.Base 2 is the plate parts that are shaped as rectangle, and it is processed through the correct grinding scraping on two planes up and down.The middle part of base 2 has technology by the centre distance in crank bore 19 and small end hole 18 and allows tool bore 17 and taper pin installing hole 13, technology allow the slightly larger in diameter of tool bore 17 in the diameter of crank bore 19, so that provide the feed space for machine tooling.On base, be provided with apical pore around taper pin installing hole 13.Small end hole swelling detent mechanism 1 is arranged on the taper pin installing hole 13, expansion set ejecting mechanism 3 is connected with the bottom of small end hole swelling detent mechanism 1, be provided with 4 bolted on connection holes 8 that are used for fixing base at base 2 middle parts, technology allows the base of tool bore 17 peripheries be provided with 3 vertical adjustment screws 6 that are used to adjust the connecting rod level, is used for the vertical location and the leveling of connecting rod.Screwed hole and the adjustable locating piece 7 of level that technology allows the base 2 of tool bore 17 sidepieces be provided with to be used for clamping work pieces are provided with pressing plate 5 on the screwed hole of clamping work pieces, be fixed with leveling cushion block 4 at the middle part of base.
Location, small end hole expansion mechanism 1 as shown in Figure 4 is made up of location taper pin 12, elastic expansion sleeve 11, swelling pressing plate 10 and clamp nut 9.Taper pin 12 middle parts, location are conical structure, its top and bottom are screwed straight-bar, elastic expansion sleeve 11 is positioned at the outside of location taper pin 12, swelling pressing plate 10 passes the top that the straight-bar of locating the taper pin top is positioned at elastic expansion sleeve 11, the straight-bar at clamp nut 9 and taper pin top, location is threaded, and the straight-bar and taper pin installing hole 13 interference fit that are positioned at taper pin bottom, location are fixed.Elastic expansion sleeve 11 as shown in Figure 6 is the cylindrical thin-walled cover of conical external diameter for endoporus, the two ends of elastic expansion sleeve 11 respectively have the dilatation fissure 21 of four certain-lengths vertically, and the position of two ends dilatation fissure 21 is interlaced, its objective is to make elastic expansion sleeve 11 under the effect of radial load, be easier to be out of shape distending.One end of dilatation fissure 21 has stop hole 22.Described location taper pin and swelling cover adopt 1: 50 taper fit.Utilize pyramidal structure to force the thin-walled cover to produce the radial elastic distortion, make the outer wall of expansion set 11 contact closely connected with the inwall of wrist-pin hole 18.The external force that swelling is required is provided by swelling pressing plate 10 by clamp nut 9.Adopt swelling to overlap quick and precisely to locate and bring great convenience to connecting rod.
As shown in Figure 5: the expansion set ejecting mechanism by eject pin rod 20, spring 14, eject flange 15, ratchet 16 is formed.The straight-bar of ratchet 16 and taper pin bottom, location is threaded, ejecting pin rod 20 is fixed on and ejects on the flange, spring 14 is socketed in and ejects on the pin rod, ejecting flange 15 is enclosed within on the location taper pin 12 bottom straight-bars between ratchet 16 and the base 2, eject pin rod 20 tops and be positioned at apical pore on the base, its effect is after the honing of connecting rod macropore machines, and is used to eject the swelling cover.Process is as follows: unclamp pressing plate 5 and clamp nut 9, take off swelling pressing plate 10, start ratchet 16 then it is clockwise rotated, make to eject flange 15 risings, promote to eject pin rod 20 and rise.When exposing highly above the base upper horizontal plane, it contacts with the lower surface of elastic expansion sleeve 11, subsequently under the effect that ejects pin rod 20, after elastic expansion sleeve 11 overcame swelling frictional force with location taper pin 12 and wrist-pin hole inwall (or wrist pin bush installing hole inwall), elastic expansion sleeve 11 broke away from the taper bolt on the taper pins 12 of location.Extract elastic expansion sleeve 11 this moment out, is rotated counterclockwise ratchet mechanism, ejects to send out the blue 15 elastic force effects by 4 springs 14 and reset, and ejects pin rod 20 and fall on the base below the plane, and so far, the whole operation that ejects is finished.
The utility model is tackled processed connecting rod and is carried out the centering location when using first.Prop up clamp device and hang onto on the M2532C planet internal grinder workbench, with this device pedestal of T type bolted, fastening limit, limit is adjusted.The method of adjusting centering is adsorption magnetic force dial framework on the main shaft of M2532C planet internal grinder, the error of perpendicularity (should be inserted in elastic expansion sleeve) of proofreading and correct location taper pin 12 respectively with the magnetic force dial gauge, and the depth of parallelism, the flatness error of base 2 horizontal planes.When perpendicularity ≯ 0.03mm/ bearing pin total length, the depth of parallelism ≯ 0.04mm/ base width, 0.10mm/ base total length, can fastening coupling bolt.With the parallel suspender of special-purpose connecting rod G shape connecting rod is hung on anchor clamps, then, by aforementioned aligning method inspection, the chucking connecting rod carries out the honing reparation when satisfying aforementioned the requirement.Operation later on need not adjusted substantially, just need regularly proofread check.
This device becomes handwork and is machine cut processing, greatly reduce labor strength, improved efficiency, saved the cost of overhaul, make the rate that renews in connecting rod year of diesel locomotive be average 5.26% by 98.6% former attenuating, overhaul 100 accounting of this series cab through reality, 368.2 ten thousand yuan of year saving costs of overhaul are brought favorable economic benefit.
