Abstract
The utility model discloses a tool for machining middle slotted holes of struts used on a brake beam of a rail wagon. The tool comprises a base, a vertical plate and limiting plates, wherein the vertical plate is vertically arranged on the top surface of the base; the limiting devices are symmetrically arranged on two lateral surfaces of the vertical plate; and each limiting plate comprises a first limiting arc plate, a second limiting arc plate, a limiting post, a first limiting screw and a second limiting screw. The utility model has the advantages as follows: two groups of limiting devices are symmetrically arranged on two lateral surfaces of the vertical plate arranged on the top surface of the base; the first limiting arc plate, the second limiting arc plate, the first limiting screw, the second limiting screw and the limiting post which are arranged in each group of limiting device are matched with one another for positioning; various parts in the limiting devices are assembled according to the structure of the strut, so that the clamping efficiency of the strut is greatly improved; and the two groups of limiting devices can be used for simultaneously clamping two upright posts for machining and machining the middle slotted holes of the struts at one step, so that the production efficiency can be effectively improved.
Description
Technical field
The utility model has related to the secondary process frock of the pillar that uses on a kind of railway freight-car brake beam, particularly the pillar middle part slotted eye processing tool that uses on a kind of railway freight-car brake beam.
Background technology
The railway freight-car brake beam is the vitals in the railway freight-car driving system, it is directly connected to the railway freight-car driving safety, and brake beam strut is the core component of brake beam, pillar mainly bears the relative load between brake beam girder and the auxiliary girder in the brake beam work progress, its loading status is complicated, for the brakes inefficacy that prevents to lose efficacy and bring because of pillar, production and processing to pillar has proposed higher requirement, pillar one end that is installed on the brake beam is processed into arc groove, this arc groove auxiliary girder middle part circular arc portion direct and brake beam coincide, its other end is provided with bayonet socket, is fixed on brake beam girder middle part after bayonet socket and clip fasten; In order to strengthen the antitorque ability of pillar and to alleviate pillar weight, process a long slot bore and axis normal at the pillar middle part simultaneously in the circular hole of long slot bore hole wall; Because the plane at long slot bore place, middle part and do not overlap with the perpendicular plane of strut ends bayonet socket, so difficulty of processing is bigger, present middle part slotted eye processing is carried out in two steps, the first step is boring, because being solid forging, produces on pillar, steel strength is higher, if directly carry out milling, not only efficient is low, and milling cutter easily also weares and teares, so, earlier got out a registration hole in the working groove hole site before formal milling, carry out milling then, milling is directly pillar to be positioned on the workbench of vertical knee-type milling machine to carry out, and once can only clamp a pillar, production efficiency is lower.
The utility model content
Technical problem to be solved in the utility model provides the pillar middle part slotted eye processing tool that uses on a kind of railway freight-car brake beam, can effectively improve the working (machining) efficiency of pillar middle part slotted eye.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the pillar that uses on a kind of railway freight-car brake beam middle part slotted eye processing tool comprises pedestal, is vertical at the riser on the base top surface and is symmetrically set in stopping means on the riser two sides; Described stopping means comprises first position stopping arch plate, second position stopping arch plate, limited post, the first spacing screw rod and the second spacing screw rod; Described first position stopping arch plate and second position stopping arch plate are fixedly mounted on the two ends of riser one side respectively, and first position stopping arch plate and second position stopping arch plate are tangent with its installed surface respectively, and the pairing axis of both arc surfaces coincides; The described first spacing screw rod and the second spacing screw rod are vertical at the bottom of riser side, distance between both axis deducts the diameter of the first spacing screw rod or the second spacing screw rod less than the length of the middle facial planes of pillar, the equal diameters of the first spacing screw rod and the second spacing screw rod, be respectively equipped with movable pressing board on the first spacing screw rod and the second spacing screw rod, both axis are on the same horizontal plane; Described limited post is located at the middle part of riser side, the axis of limited post and the distance of plane, the axis place in the vertical direction of the first spacing screw rod and the second spacing screw rod equal pillar middle part round hole axial and two middle facial planes paralleling with its axis between distance add the diameter of limited post and the first spacing screw rod or the second spacing screw rod.
Adopt the beneficial effect that technique scheme produced to be: to be located at and to be arranged with two groups of stopping means on the riser two sides on the base top surface, first position stopping arch plate that is provided with in every group of stopping means, second position stopping arch plate, the first spacing screw rod, the second spacing screw rod and limited post cooperate and position, each several part in the stopping means all assembles according to the structure of pillar, and on the first spacing screw rod and the second spacing screw rod, the pressing plate that compresses with nut is set, direct and the pillar vertical plane applying of two block pressur plates, realization compresses, and improves pillar greatly and clamps efficient; Two groups of stopping means can clamp two root posts simultaneously and process, and can once carry out the processing of two root posts middle part slotted eye, effectively enhance productivity.
