Abstract
The utility model discloses a semi-automatic rivet-pulling machine for withdrawing the rivets on a holder when the rolling bearing of the railway vehicle is separated for being checked and repaired, comprising a working table mechanism, a stamping mechanism, a rivet-pulling mechanism, a hydraulic transmission system and an electric control system. The semi-automatic rivet-pulling machine can accurately and effectively withdraw the rivets fastened on the holder without damaging the holder. The semi-automatic rivet-pulling machine adopts the control giving priority to the hydraulic transmission and automatically finishes the process of punching the nail, clipping the nail, pulling the nail, placing the nail, resetting, etc.; the time only needs 6 seconds; the labor strength can be reduced and the efficiency can be enhanced. The rivet-pulling mechanism and the hydraulic transmission system of the machine have peculiar and compact structure; the maximum thrusting force reaches 1.6 tons; the maximal pulling force reaches 0.9 tons; the power consumption is 0.75KW; the weight is 300KG.
Description
The utility model belongs to the improvement of rail truck rolling bearing maintenance machine tool.
For a long time, when the rail truck rolling bearing need overhaul, at first to disassemble parts such as the outer ring of rolling bearing, retainer, roller, generally be on special-purpose shear pin machine, the manufactured head on the retainer to be cut off earlier, and then rivet is rushed out from retainer with instruments such as hand hammer, punching pines, could disassemble parts such as the outer ring of rolling bearing, retainer, roller like this, owing to be that manually-operated, labour intensity are big, efficient is low, and the retainer that is decomposed damages easily, is out of shape so that scrap.The Nail punch tool that is adopted in recent years, be that the rivet that cuts off ailhead is rushed out in retainer, because rivet diameter has only 70 millimeters of 4～5 millimeters, length, thereby punching pin needs thin and grow, easy unstability bending when elongated like this punching pin dashes nail causes the rivet retainer.Hole damage was lost efficacy, even rivet on the retainer can't be gone out by jam-packed and made retainer scrap.
The purpose of this utility model provides a kind of semi-automatic rivet driver that pulls out, it can be extracted fastening rivet accurately and effectively and not damage retainer, following closely-reset whole process from punching press nail-clip nail-nail pulling-put simultaneously carries out automatically, time only needs 6 seconds, can reduce labor intensity greatly and increase work efficiency.
Accompanying drawing 1 is a structure chart of the present utility model, semi-automatic pull out rivet driver by table mechanism (1), punching mechanism (2), pull out rivet mechanism (3), Hydraulic Power Transmission System (4) and electric-control system (5) and form.The rolling bearing to be disintegrated that cuts off manufactured head is placed on the table mechanism (1), workbench is provided with the location and foot-operated contraposition mechanism helps contraposition, after the normotopia, press operating switch, button K1, punching mechanism (2) action, punching pin stamps out 7 millimeters with the rivet in the retainer, after reset, then pull out rivet mechanism (3) action, the part that the manipulator crimping rivet is rushed out, extract rivet then, manipulator opens, and rivet falls collection, processes such as whole punching press-reset-clamp-extract-open-reset by Hydraulic Power Transmission System (4) and electric-control system (5) automatically control carry out, finish one and pull out the rivet cyclic process and only need 6 second time.
2～7 the utility model embodiment further specify structural principle in conjunction with the accompanying drawings.
Fig. 2 is the Hydraulic Power Transmission System schematic diagram, and Fig. 3 is the electric-control system circuit diagram, presses pump switch QA, oil pump CB-B10 starting lift-rising oil pressure, and each oil cylinder colludes shellfish and rises, limit switch 1 * K pressurized, electromagnetic valve 1DT energising, oil hydraulic system off-load.When pressing operating switch K1, electromagnetic valve 1DT outage, the 2DT energising, oil hydraulic system pressure is 15kg/cm
2, punching press oil cylinder (1) action (22 millimeters of strokes) punch rivet, piston rod is met limit switch 2 * K, 2 * K pressurized, electromagnetic valve 2DT outage, punching press oil cylinder (1) colludes shellfish and automatically resets, electromagnetic valve 3DT energising simultaneously, clamping cylinder (3) action, behind manipulator (2) crimping rivet, hydraulic pressure cuts down (6) automatic reverse in proper order, hoist cylinder (4) action (70 millimeters of strokes), rivet is extracted, piston rod is met limit switch 3 * K, 3 * K pressurized, electromagnetic valve 3DT outage, manipulator (2) opens, rivet comes off, and hydraulic pressure cuts down (5) automatic reverse in proper order, and hoist cylinder (4) rises and resets, oil cylinder is met limit switch 1 * K, makes 1 * K pressurized.One is pulled out the end of rivet course of action, is returned to original state, and required time is 6 seconds.Whole six actions of pulling out oil cylinder in the rivet process are cut down in proper order with three limit switches by two hydraulic pressure and are come switching signal.If in the time of need pulling out second rivet, then press operating switch K1 again, nail pulling carries out automatically by above-mentioned process again.
Fig. 4 pulls out rivet mechanism and is made up of manipulator (1), clamping cylinder (2), hoist cylinder (3) for pulling out rivet mechanism structure chart, a shared special public oil cylinder cover (4) between oil cylinder (2) and (3).
Fig. 5 is public oil cylinder cover structure chart.
Fig. 6 provides the robot manipulator structure figure that pulls out rivet mechanism, manipulator is to adopt the central shaft slidingtype, and physical dimension is that fulcrum is apart from (L)=60mm, pincers hand radius (R)=93mm, slip angle (β maX)=38 degree, sliding stroke (5)=8mm.
Fig. 7 is a Hydraulic Power Transmission System integrated package structure chart, it is made up of small-sized integrated package (1) and the mount pad (2) of four 112 * 102 * 72mm, mount pad (2) is connected with fuel tank, all be drilled with the path of hydraulic oil in every small-sized integrated package, and communicate with separately Hydraulic Elements, operating cylinder and fuel tank, oil pump respectively, Hydraulic Elements (3) (as electromagnetic valve etc.) are installed in respectively on the relevant position of small-sized integrated package (1), thereby form whole Hydraulic Power Transmission System.
The utility model has the advantage of method that the main usefulness of removing of rivet is extracted rather than with the method for going out, can guarantee that like this rivet can extract exactly and do not damage retainer. The process of whole punching press, nail pulling is finished automatically, can improve 5 times of work efficiency. Compact mechanical structure, hydraulic drive thrust can reach 1.6 tons, and force pulling reaches 0.9 ton. Only 0.75 kilowatt of power consumption, only 300 kilograms of weight.
