Abstract

The utility model discloses a special preprocessing fixture for middle slots of a brake beam strut, which belongs to tool equipment in production of railway vehicle accessories and comprises a support component and a clamping component. The support component includes a top plate, a middle plate and a base, the top plate, the middle plate and the base are all square steel plates and fixedly connected to form an I-shaped support, and two rows of round holes equal in sizes are uniformly distributed on the surface of the top plate. The clamping component includes pre-tightening plates, at least one lead screw, at least four clamping plates and end groove positioning plates, two ends of each lead screw are provided with threads matched with the pre-tightening plates, the middle of each lead screw penetrates through the middle plate and fixedly connected, the end groove positions plates are fixed to one end of the middle plate, an arch grooved steel plate is arranged at one end of each clamping plate, and the clamping plates are symmetrically fixed to the middles of the two lateral sides of the middle plate. The special preprocessing fixture can be used for positioning a brake beam strut conveniently, is convenient in operation and high in processing procession, further, two workpieces can be fixed by the special preprocessing fixture simultaneously, and accordingly processing efficiency is increased.

Description

Slotted eye preprocessing special tooling in the middle of the brake beam strut
Technical field
The utility model relates to a kind of frock equipment that the rolling stock accessory is produced that is used for, slotted eye preprocessing special tooling in the middle of especially a kind of brake beam strut.
Background technology
In the accessory of rolling stock, brake beam strut plays a part very important.Because the structure more complicated of brake beam strut needs the processing through a lot of operations in manufacturing process.Under the traditional mode of production mode, during the slotted eye of processing brake beam strut centre, normally process several circular holes at the desired location of pillar, use then by anchor clamps and be fixed on the plain-milling machine, be milled into the pillar medial launder.This mode of production exists some not enough: 1. with common or existing frock is very difficult that the special part of this structure is fixed processing, promptly allowing to produce with this frock, also is single-piece production usually; The waste plenty of time when 2. clamping fixedly, and final product also is difficult to guarantee its required precision.On the whole, traditional brake beam strut production and processing cost are big, and efficient is low, therefore need design a kind of tooling device of special use to brake beam strut.
The utility model content
The technical problems to be solved in the utility model provide a kind of can increase work efficiency and the brake beam strut of machining accuracy and easy operating in the middle of slotted eye preprocessing special tooling.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: slotted eye preprocessing special tooling in the middle of a kind of brake beam strut, it is characterized in that: comprise support component and screens parts, described support component comprises top board, intermediate plate, base, described top board, intermediate plate and base are square plate, the three is fixedly connected as the I shape supporting seat, described top board surface is evenly equipped with the identical circular hole of two row's sizes, the screens parts comprise the pretension plate, leading screw, block board and end grooves location-plate, described leading screw is provided with one at least, two ends are provided with the screw thread that cooperates with the pretension plate, intermediate plate and fixedly connected is passed at the middle part, and described end grooves location-plate is fixed in intermediate plate one end, and described block board one end is the steel plate of circular groove, it is provided with four at least, is symmetrically fixed on the middle part of intermediate plate two sides.
The middle part, side of described intermediate plate is symmetrically welded four passive support bar.The brake beam strut frame keeps balance in two above the support bar, enables convenient tight with the pretension integrated circuit board.
The utility model is the left-right symmetry structure, fix two brake beam struts simultaneously, the end slot of brake beam is by the screens of end grooves location-plate, the mid portion frame is on support bar, and live by intermediate plate and pretension integrated circuit board, make it to be completely fixed, by the locating hole on top board surface, process middle slotted eye then with drilling machine.Whole Design of device size and brake beam strut size meet fully, can be fine, fixing brake beam strut very easily.
Adopt the beneficial effect that technique scheme produced to be: 1., can locate fastening brake beam strut very easily according to the utility model structure of brake beam strut configuration design, easy to operate, the machining accuracy height; 2. the utility model is a symmetrical structure, can fix two workpiece simultaneously, has improved working (machining) efficiency.
