The specific embodiment
Referring to Fig. 1, the utility model adopts the modularized design manufacturing, with CRH3 EMU underframe side bar, roof side bar, floor weldering former piece combined type processing tool is example, and whole processing tool is made up of 19 groups of identical removable crossbeams 1, is evenly distributed on 26 meters the position of foetus.Because CRH3 EMU underframe side bar, roof side bar, floor weldering former piece all are left and right symmetrical parts, so whole frock is furnished with symmetrical two row's processing stations.Two longerons 2 are installed on 19 crossbeams 1, several are installed on longeron 2 clamp unit 3,, adjust the position that clamps unit 3 according to different workpiece.The processing arrangement of vertical profile is at an end of longeron 2, and the processing arrangement of bent section, inserts bent section in the station of vertical profile because station length is not enough at the other end of longeron 2, and shared two groups clamp unit 3, are independent of each other.Use this frock, need not adjust the position that clamps unit 3, just change different locating pieces 13, just can realize the processing of 30 kinds of workpiece of five kinds of section section bars according to different section section bars.
Referring to Fig. 2～Fig. 8, the unit 3 that clamps of frock is made up of basis seat 17, clamp mechanism and locating piece 13, locating piece 13 is installed on the basis seat 17, by a key, a finger setting, different section material sections is changed different locating pieces 13, and CRH3 EMU underframe side bar, roof side bar, floor weldering former piece combined type processing tool have 5 kinds of locating pieces: underframe side bar locating piece, flat-top side bar locating piece, anti-locating piece, floor weldering former piece locating piece and the dome side bar locating piece adorned of flat-top side bar.
Clamp mechanism has three kinds: compound clamp mechanism, the vertical clamp mechanism of presser type and side direction clamp mechanism. and compound clamp mechanism promptly can play vertical clamping action, can play the side direction clamping action again; The working position positions close with clamping device such as place, doorway, both ends that the vertical clamp mechanism of presser type is used for the underframe side bar add stepping up of man-hour, in order that do not hinder the operation of machine tool chief axis head, when using this clamping device, compound clamp mechanism fallen got final product, otherwise, when using compound clamp mechanism, the vertical clamp mechanism of presser type to be fallen and got final product mutually noninterfere. the side direction clamp mechanism mainly helps out.
Referring to Fig. 2, too high with compound clamp mechanism during the end of processing underframe side bar (nearly 24 meters long) because this position processing capacity is big, hinder the rotation of main tapping, influence is processed, so with the vertical clamp mechanism of presser type.The working position of side bar in the end in 2 meters left side, right side, top have, clamping is finished processing for No. one time, only switches pressing plate, thus about all established hold down gag.The side direction clamp mechanism is arranged in addition.Compound clamp mechanism is in rest position, is used to process compressing of other parts.
Referring to Fig. 3, during the middle part of processing underframe side bar (nearly 24 meters long), because processing capacity is few, used hold-down mechanism is compound clamp mechanism, and is easy to use flexible.The side direction clamp mechanism is arranged in addition.
Referring to Fig. 4, during processing limit flat-top forward, the limit flat-top have 7 meters long, 4 meters long, according to its design feature, adopt compound clamp mechanism comparatively suitable.
Referring to Fig. 5, flat-top reverse processing and loading clamp in limit uses vertical clamp mechanism of presser type and side direction clamp mechanism.
Referring to Fig. 6, when processing crooked side bar, because crooked side bar length overall is more than 6 meters, working position is more again, hinders main shaft to process with compound clamp mechanism, so all with the vertical clamp mechanism of presser type.The processing of crooked side bar is arranged in one side of the whole position of foetus, and each basis seat 17 is arranged to bending, coincide with workpiece.The side direction clamp mechanism is arranged in addition.
Referring to Fig. 7,17 meters of floor weldering former piece length adopt compound clamp mechanism, and are easy to use flexible.The side direction clamp mechanism is arranged in addition.
Referring to Fig. 8, dome Workpiece length 17,19,23 meters differences in limit adopt compound clamp mechanism, and are easy to use flexible.The side direction clamp mechanism is arranged in addition.
Enumerate the processing of an IC03 body frame side bar below, the using method of this frock is described.
24 meters long of IC03 body frame side bar length, working position are the termination of the 2.4 meters strong points in two ends, 1.6 meters long doorways, left and right sides muscle portion or the like, each hole at side bar middle part in addition.
According to Workpiece length, each workpiece is installed in 10 groups and clamps on the unit.The mode that clamps shown in Figure 2 is adopted in end 2 groups (4 groups at two ends), with the special-purpose locating piece of underframe side bar location, compresses with outer side guide earlier; The mode that clamps shown in Figure 3 is adopted for 6 groups in the middle part, with the special-purpose locating piece of underframe side bar location.That workpiece processes is top, behind end face, medial surface and the middle part machining area, 2 groups of (4 groups at two ends) outsides of free end presser device, side guide compresses in changing into, the working position in the reprocessing workpiece end outside.After whole the machining, unclamp side direction, upper part pressing device, hang out workpiece.
During concrete enforcement, longeron 2 can be used, also longeron 2 can be do not used, but being clamped unit 3, several are directly installed on the crossbeam 1, the location, the clamping device structure is constant, and location, the clamping of the different working positions of different product are realized in moving beam 1 position when processing different products.
