Description
Affiliated technical field
The utility model relates to a kind of mechanical equipment, specifically rail vehicle wheel equipment axle press-fitting machine that, brake disc etc. and axial compression installation and dismantling are moved back.
Technical background
Existing axle press-fitting machine is by two fixed beams and press-fit oil cylinder, pull bar, carriage dolly, chassis, measurement mechanism etc. and form, and does not have portable beam, can only press-fit and can not tear open and move back wheel (dish).What have has a portable beam, fixed beam and tailstock, wheel (dish) right tearing open and adorn all carried out between fixed beam and portable beam, according to the length of axle and the position of wheel (dish), portable beam can be along the pull bar axial traveling, with gib portable beam is fixed on the different place of pull bar, tailstock does not bear the load of dismounting, fixed beam and portable beam are formed a stressed framework by gib and pull bar, because axle or dish will embed the portable beam center, so are a bigger U type opening in the middle part of the portable beam, so that the turnover of workpiece, portable beam rigidity is bad when press-fiting, stressed asymmetric situation can occur, produce the elastic deformation of deflection, influence press-fits precision.
Summary of the invention
The purpose of this utility model provides and a kind ofly can press-fit by accuracy control, can tear the axle press-fitting machine that moves back wheel (dish) open again.
Axle press-fitting machine of the present utility model is by two fixed beams (contain and press-fit oil cylinder), pull bar, and portable beam and carriage dolly, measurement mechanism and chassis are formed.
Wheel (dish) carries out being fitted between two fixed beams and the pull bar, portable beam and gib do not bear and press-fit load, portable beam can be along pull rod shaft to initiatively walking or servo-actuated, and when two pull bar verticals are arranged, the carriage dolly also can move along the direction vertical with pull bar, be convenient to the turnover of workpiece, the mobile idler pulley of carriage dolly can be installed on the portable beam, also can be installed on the chassis, moving of carriage dolly can be with the portable beam axial motion, also can be along guide rail axial motion or the edge horizontal motion vertical with pull bar, portable beam only is equivalent to the part of carriage dolly.Press-fit precision by measurement mechanism observing and controlling, the sounding rod in the measurement mechanism can move axially or servo-actuated in the support holes on the portable beam beam body.
Wheel (dish) right tearing open moved back at portable beam and had between the fixed beam that press-fits oil cylinder and carry out, and portable beam bears the load of tearing open when moving back by the gib on the pull bar, and another fixed beam is not worked at this moment, is equivalent to the tailstock in the original axle press-fitting machine.
When tearing the wheel shaft that moves back brake disc open, when three or four brake discs are arranged especially, axle press-fitting machine has two special mould clamps, the thickness of a jig is greater than the distance between dish core and the core wheel, the thickness of a jig is less than the distance between dish core and the core wheel, the flange of jig links to each other with portable beam with bolt, jig is installed in the center, U type hole of portable beam, because it is less that brake disc is torn the power of moving back open, with the jig of thickness brake disc is press-fited toward the axletree the inside less than the distance between dish core and the core wheel, to increase the distance between brake disc dish core and the wheel core wheel, this moment jig can ampere on the flange of the either side of portable beam, enter between wheel core wheel and the dish core with the bigger jig of thickness again, carry out the work of moving back of tearing open of wheel.

Fig. 3 is the cut-away view of Fig. 2.
Fig. 4 is two of a special mould clamp of the present utility model.
Fig. 5 is the cut-away view of Fig. 4.
Among the figure 1, fixed beam, 2, pull bar, 3, the carriage dolly, 4, gib, 5, carriage dolly axial guidance, 6, the carriage vehicle guide vertical with pull bar, 7, portable beam, 8, measurement mechanism, 9, the fixed beam that press-fits oil cylinder is housed, 10, the chassis, 11, workpiece, 12, flange, 13, dop, 14, connecting cylinder.
The specific embodiment
Fig. 1 is an example structure scheme drawing of the present utility model, 1 is fixed beam among the figure, 2 is pull bar, 3 is the carriage dolly, 4 is gib, 5 is carriage dolly axial guidance, 6 is the vertical aspect with pull bar of carriage dolly guide rail, and 7 is portable beam, and 8 is measurement mechanism, 9 for being equipped with the fixed beam that press-fits oil cylinder, 10 is the chassis, and 11 is workpiece, and axle press-fitting machine two pull bars are to arrange along the direction of hanging down, portable beam can be promoted to move axially or move axially with workpiece along the guide rail on the chassis by special oil cylinder, press-fit wheel (dish) to the time, portable beam only is equivalent to the part of carriage dolly, does not bear the load that press-fits, gib is opened, do not stress, the moving guide rail of carriage dolly is located on the portable beam, can move along both direction, make things convenient for the turnover lifting of workpiece and wheel (dish) right press-fit observing and controlling, the sounding rod in the measurement mechanism can mobile or servo-actuated in the support holes on portable beam beam body under the driving of measuring cylinder.
Tear open when moving back wheel (dish), fixed beam 1 is not worked, and portable beam is fixed on the pull bar with gib 4 after moving certain position, and workpiece is torn open and moved back wheel (dish) at portable beam and fixed beam and press-fit between the oil cylinder and carry out, and is the same with former axle press-fitting machine.Such axle press-fitting machine had both guaranteed that high-precision to press-fit wheel (dish) right, had again and tore the function of moving back wheel disc open.
When tearing open when moving back wheel (dish) with brake disc, because the distance between dish core and the core wheel is very little, it is stressed bigger to tear the jig that moves back usefulness open, and strength and stiffness are bad, the utility model has two special mould clamps, the thickness of a jig is greater than the distance between dish core and the core wheel, and as Fig. 2, shown in Figure 3,12 is flange among the figure, 13 is dop, Fig. 3 is the cut-away view of Fig. 2, and S1 represents the thickness of dop, greater than the distance between dish core end face and the core wheel end face; The thickness of a jig is less than the distance between dish core and the core wheel, as Fig. 4, shown in Figure 5,12 is flange among the figure, 13 is dop, Fig. 5 is the cut-away view of Fig. 4, and 14 is connecting cylinder, and dop and connecting cylinder insert in the portable beam U type hole, S2 represents the thickness of dop, less than the distance between dish core end face and the core wheel end face; Since brake disc to tear the power of moving back open less, make dop 13 withstand on brake disc dish core end, brake disc is press-fited toward the axletree the inside, to increase the distance between brake disc dish core and the wheel core wheel, carry out the work of moving back of tearing open of wheel with Fig. 2, bigger jig shown in Figure 3 then, because the tearing open of wheel move back need be bigger power, jig needs bigger strength and stiffness.
Fig. 4, jig shown in Figure 5 also can be installed on the opposite side flange of portable beam, have Fig. 2, the same structure of jig shown in Figure 3, do not have connecting cylinder, are born by the tie bolt of flange and tear the load that moves back brake disc open.Also can make two jigs have identical structure, and be installed on the flange of portable beam the same side by the position of mobile portable beam and gib.
