Slotted eye preprocessing special tooling in the middle of the brake beam strut
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.
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.

The specific embodiment
From accompanying drawing 1-3 as can be seen, the utility model relates to the middle slotted eye preprocessing of a kind of brake beam strut special tooling, it is characterized in that: comprise support component and screens parts, described support component comprises top board 1, intermediate plate 8, base 4, described top board 1, intermediate plate 8 is a square plate with base 4, the three is fixedly connected as the I shape supporting seat, described top board 1 surface is evenly equipped with the identical circular hole of two row's sizes, the screens parts comprise pretension plate 2, leading screw 3, block board 5 and end grooves location-plate 7, described leading screw 3 is provided with one at least, two ends are provided with the screw thread that cooperates with pretension plate 2, intermediate plate 8 and fixedly connected is passed at the middle part, and described end grooves location-plate 7 is fixed in intermediate plate 8 one ends, and described block board 5 one ends are the steel plate of circular groove, it is provided with four at least, is symmetrically fixed on the middle part of intermediate plate 8 two sides.
4 occupation mode of the present utility model is described with reference to the accompanying drawings: at first in the hypotenuse of the end grooves screens end grooves location-plate 1 of brake beam strut, integral body is positioned on the support bar 6, twist the bolt at screw thread place on the leading screw 3 then by spanner, bolt will promote pretension plate 2, pretension plate 5 is contacted with brake beam strut, circular arc portion cooperates with the circular arc place of block board 5 in the middle of the brake beam strut, and brake beam strut is sticked into, and retrains its whole frees degree; This device can be fixed two brake beam struts simultaneously, and is fastening by four pretension plates at two leading screws 3 and leading screw 3 two ends.The utility model places on the operating desk of drilling machine, utilizes the location of two rounds on the top, can conveniently process the middle slotted eye of brake beam strut, and promptly preprocessing hole 9.
