Description
Technical field
The present invention relates to the frock equipment that a kind of rolling stock accessory is produced, in particular for railway freight-car with side bearing bottom surface Milling Process special tooling.
Background technology
Along with socioeconomic continuous development and progress, increasing to the quantitative requirement of rolling stock, also increasingly high to the workmanship requirement of locomotive.Railway freight-car generally comprises car body, bogie, brake apparatus, parts such as coupler and draft gear.Wherein, the effect of bogie is a supporting body, and guided vehicle is along rail running.
Side bearing is arranged on the two ends with vehicle operating direction vertical beam, and on the position near wheel, its effect is the pressure that beam is caused in order to buffering Ackermann steer angle compartment outward inclining.At present; Domestic and international most of quick railway goods train bogie all adopts elastic side bearing; This side bearing had both suitably increased the steering resistance distance of vehicle through choosing suitable steering resistance distance, had prevented that again steering resistance is apart from excessive; Improve the speed of service of vehicle, improved the curve negotiation ability of vehicle.The pedestal of this side bearing of general cooperation is a side bearing, in the side bearing process, because manufacturing procedure is many; And lack special fixture, can only single-piece work, and all need artificial fixing at every turn; Alignment correction position, size etc., it is poor to cause the manufacturability of side bearing processing, and the production cycle is long; Working (machining) efficiency is low, causes the waste of manpower and materials.
Summary of the invention
The technical problem that the present invention will solve provides a kind of in the side bearing process, improves the side bearing bottom surface Milling Process special tooling of bottom surface working (machining) efficiency.
For solving the problems of the technologies described above, the technical scheme that the present invention taked is: a kind of railway freight-car is characterized in that with side bearing bottom surface Milling Process special tooling: comprise transmission mechanism, hold-down mechanism and fixture;
Said fixture includes closure casing and cross-arm and the dividing plate that first member plate, middle plate, base plate and right end plate are formed; The plate upper surface is provided with guide-track groove and through hole in said; Plate level is fixed in said first member plate and right end plate middle part in said; The both sides, top of said first member plate and right end plate are fixed with said two cross-arms, are evenly equipped with dividing plate between said two cross-arms;
Said hold-down mechanism comprises left briquetting and right briquetting, and the bottom of said left briquetting and right briquetting is connected in the guide-track groove of said middle plate through square head bolt;
Said transmission mechanism comprises upper push-rod, lower push-rod, adjustable push rod, pushing block, reservoir, first lever and second lever; The piston rod of said reservoir passes first member plate and is connected through universal joint with lower push-rod one end; Said first lever and right end plate are hinged through central pin shaft, and said first lever lower end and middle part are hinged with lower push-rod and adjustable push rod respectively, and its upper end compresses right briquetting through pushing block; The through hole of plate during said second lever passes; Its lower end is connected with adjustable push rod, and upper end and upper push-rod are hinged, and said upper push-rod passes left briquetting and is connected with right briquetting.
The contact-making surface of the said pushing block and first lever is provided with oblique groove.The present invention is delivered to right briquetting to the power of first lever through pushing block is set, and oblique groove is set on pushing block, when first lever rotates, guarantees an end and slides along groove; When design structure of the present invention; Because the size according to the required side bearing that compresses designs; Require left briquetting and the right briquetting too big distance of need not moving, therefore design groove and can guarantee under the effect of first lever, the displacement of convenient left briquetting of adjustment and right briquetting.
The both sides that said upper push-rod passes left briquetting are provided with two limited blocks, and the spacing of said two limited blocks is greater than the thickness of left briquetting.About the big 15mm of thickness of the gap ratio briquetting of operated by rotary motion two limited blocks, with conveniently unclamp, action gap when compressing.
Said left briquetting and both sides, right briquetting top are provided with the triangle convex edge.
The axis that the set universal joint of the present invention can solve piston rod and lower push-rod does not overlap; Exist under the situation of certain angle, thrust is transmitted over smoothly, because first lever is the central pin shaft rotation around the hinged place among the present invention; Therefore in the process that clamps side bearing; Lower push-rod is not to be in horizontal direction always, therefore is provided with universal joint in both junctions, to guarantee that power can smooth transfer in the structure.The present invention cooperates production miller to use, and integral body places on the workbench of milling machine, fixes through the T type groove fitted bolt of workbench.The present invention is mainly used in the clamping side bearing, limits its whole frees degree, and action principle is: utilize reservoir as power source, drive transmission mechanism and hold-down mechanism, accomplish the clamping of side bearing, convenient processing.
Action of the present invention is that the parallel connection action under the transmission of first lever of lower push-rod and adjustable push rod is arranged; Moved by the second lever drives upper push-rod and to realize, when lower push-rod moves right, this moment, first lever and second lever were to anticlockwise; What realize is to clamp side bearing; Otherwise,, then unclamp side bearing left when lower push-rod moves.
Adopt the beneficial effect that technique scheme produced to be: the present invention utilizes the acting in conjunction of lever mated connecting rod; Realized fastening to side bearing in the railway freight-car having realized that the batch of workpiece is fixed, handled easily; Can improve working (machining) efficiency, and save production cost.
