Abstract
A central hole positioning wheel pair press comprises a machine frame, an oil cylinder device, thimble devices, a dolly, a detection device, a hydraulic system and an electric control system, wherein the oil cylinder device is axially and symmetrically arranged in the machine frame; one head of the oil cylinder device is a main pressure oil cylinder, and the other end of the oil cylinder device is an auxiliary oil cylinder; a big piston rod is arranged in the main pressure oil cylinder of the oil cylinder device; a small piston rod is arranged in the big piston rod; a right pressing head seat is installed at the end part of the big piston rod; a thimble device is installed at the end part of the small piston rod and another thimble device is installed at the end part of the piston rod of the auxiliary oil cylinder; and a left pressing head seat is sleeved outside the auxiliary oil cylinder and is fixed at the inner side of the left side of the machine frame. The utility model has the beneficial effects that compared with a double-headed oil cylinder press, a movable beam and a plug board are omitted, a positioning groove (hole) and a locking mechanism are also omitted, the structure is simplified, and a control part is simplified; and as the auxiliary oil cylinder at the other end is small, the cost is reduced. Compared with a lengthening bar and pendulum press, the press finishes the pressing through positioning a central hole, can not cause any damage to a shaft and the end of the shaft and is more favorable for improving the pressing quality and the safety of a train.
Description
Technical field
The utility model relates to rail vehicles equipment machinery, is applicable to different gauge locomotives such as a meter rail, standard gauge, broad gauge, urban track traffic (subway, light rail), with assembling, inspection pressure or squeeze test and the back-pressure test of wheel, axletree, brake disc, reduction box or the similarity piece of the passenger vehicle of 2～3 brake discs, general wagon etc.Be specially adapted to right automatically the press-fiting of bullet train wheel.
Background technology
Because the fast development of bullet train with widely-used, causes the right design of vehicle wheel to be brought in constant renewal in, its assembly and disassembly etc. has had higher requirement, and then the mechanical innovation of constantly following up of also feasible corresponding equipment.At present corresponding pressing machine and dismounting machine mainly contain two kinds of citation forms: wherein a kind of type is the single head oil cylinder, realizes press-fiting and moving back the needs that unload through in frame, establishing extension bar and pendulum; Another kind then is the double end oil cylinder, cooperates to reach and press-fits and move back the purpose of unloading through walking beam and plate and detent mechanism are set in frame.Up to the present, though had much press-fit, the dismounting machine patented product, satisfied the market demand behind the train speed raising, but still disliked perfect inadequately, desirable not to the utmost.
Summary of the invention
In order to solve the deficiency of prior art, the utility model provides a kind of centre bore location Press Fit Device for Wheelset, and its designs simplification is press-fited by the centre bore location, and automaticity is high, and cost reduces.
In order to achieve the above object, the technical scheme of the utility model is a kind of centre bore location Press Fit Device for Wheelset; Comprise frame with and interior axial symmetrically arranged cylinder apparatus, push pin device, dolly, checkout gear, hydraulic system, electric-control system, it is characterized in that: one of described cylinder apparatus is main compressing cylinder, the other end is an auxiliary cylinder; Be provided with the big piston bar in its main compressing cylinder, be provided with small piston rod in the big piston bar, the big piston boom end is equipped with right pressing head seat; Push pin device is equipped with in the small piston rod end; Push pin device is equipped with in the piston rod end of its auxiliary cylinder, and left pressing head seat is sleeved on outside the auxiliary cylinder, is fixed on the inboard on the frame left side.
Described left and right pressing head seat constitutes by watt shape plate of two parallel opposed longer sides, which is provided with the folding oil cylinder.
Be provided with briquetting before the described push pin device.
The beneficial effect of the utility model is, compares with double end oil cylinder pressing machine, and it has saved walking beam and plate, has also saved locating slot (hole) and retaining mechanism, and designs simplification has also been simplified control simultaneously partly, and the other end auxiliary cylinder is very little, therefore reduces cost.Compare with the pressing machine of extension bar and pendulum, press-fit, can not cause any hurt, be more conducive to raising and press-fit quality, be particularly conducive to the safety of train axle and axle head through the completion of centre bore location.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.To shown in Figure 7, the utility model discloses a kind of centre bore location Press Fit Device for Wheelset like Fig. 1, comprise frame 1 with and interior axial symmetrically arranged cylinder apparatus, push pin device 2, dolly 3, checkout gear 4, hydraulic system, electric-control system; It is characterized in that: one of described cylinder apparatus is main compressing cylinder 5, and the other end is an auxiliary cylinder 6, is provided with big piston bar 51 in its main compressing cylinder; Be provided with small piston rod 52 in the big piston bar; The big piston boom end is equipped with right pressing head seat 7, and push pin device 2 is equipped with in the small piston rod end, and push pin device 2 is equipped with in the piston rod end of its auxiliary cylinder; Left side pressing head seat 8 is sleeved on outside the auxiliary cylinder, is fixed on the inboard on the frame left side.
Described right pressing head seat 7 is made up of watt shape plate 71 of two parallel opposed longer sides, which is provided with folding oil cylinder 72; Left side pressing head seat 8 is made up of watt shape plate 81 of two parallel opposed longer sides, which is provided with folding oil cylinder 82.
Be provided with briquetting 21 before the described push pin device, prevent to damage thimble.
The utility model course of work is following:
To take turns earlier being sleeved on the axle, and place on the dolly, behind the entering pressing machine, the two ends pressure head is closed, and two push pin device holds wheel axle end surface and measures axial length under the propelling of auxiliary cylinder 6 and small piston rod 52.The right side pressure head is opened under the effect of folding oil cylinder 72 then, and then withstands right wheel wheel hub, press-fits right wheel and puts in place; The right side pressure head closes up afterwards, withstands the right side axle head, and the left side pressure head is opened under the effect of folding oil cylinder 82, withstands the revolver wheel hub, and the right oil cylinder (being big piston bar 51) apical axis that advances is press-fit into place until revolver.Press-fit that the axletree two ends hold the location by two push pin device all the time in the process, on the dolly two are supported on that press-fit in the process can servo-actuated, have realized not reversing end for end to press-fit, and have wholely press-fited process and simplify, and automaticity is high.
Press-fit wheel to before press-fit brake disc process with press-fit wheel to identical, the cabinet in the middle of the wheel shaft is after assembling on the dolly, to get into pressing machine again, it is right with wheel to press-fit brake disc.
