Below the first bogie side frame 200 and the second bogie side frame 300 are described in detail.The first bogie side frame 200 and the second bogie side frame 300 can have suitable version, and are not limited to the version shown in Figure of description, as long as broad ways moves toward each other, thereby realize that the adjustment of the two spacing gets final product.
But preferably, as shown in Figure 2, described the first bogie side frame 200 and the second bogie side frame 300 include bogie side frame body 210 and sidepiece locator, and bogie side frame body 210 has along its length and to extend and isolated the first longeron 301, the second longeron 302 and the 3rd longeron 303 from the top down successively;
Described sidepiece locator comprises: the first locator 500, this first locator 500 are slidably disposed on described the first longeron 301, for the top of the side to described automobile body, position and clamp; The second locator 600, this second locator 600 are slidably disposed on described the second longeron 302, for the middle part of the side to described automobile body, position and clamp; With the 3rd locator 700, the three locators 700, be arranged on described the 3rd longeron 303, for the bottom of the side to described automobile body, position and clamp.
The first bogie side frame 200 and the second bogie side frame 300 have bogie side frame body 210, and the effect of this bogie side frame body 210 is mainly to play the effect that is arranged on each sidepiece locator on this bogie side frame body 210 of supporting.For example, as shown in Figure 3, bogie side frame body 210 comprises many root posts, so that interconnect with many longerons of bogie side frame body.But the present invention is not limited to this, and the bogie side frame body also can have other suitable versions, as long as can realize supporting or fixing to the first longeron 301, the second longeron 302 and the 3rd longeron 303.
In order to support and arrange the locator that positions respectively clamping to the upper, middle and lower of automobile body side, bogie side frame body 210 has along its length and to extend and isolated the first longeron 301, the second longeron 302 and the 3rd longeron 303 from the top down successively, as shown in Figure 3.When the first bogie side frame 200 or the second bogie side frame 300 broad ways moved, each bogie side frame and its each longeron together moved.Here, by corresponding locator is set on the first longeron 301, the second longeron 302 and the 3rd longeron 303, (from length direction, observing vehicle body side) can realize positioning three positions to the contour shape as arc of automobile body side (can referred to as " three-point fix "), thereby obtains the effective control to the automobile body contour shape.
Certainly, the present invention is not limited to this, and is less and to the less demanding occasion of automobile body contour shape for the automobile body size, two longerons also can be set, and on these two longerons, locator be set respectively; Perhaps, and the occasion of having relatively high expectations large for the automobile body size, can arrange four longerons, and locator is set respectively on each longeron, but will note the problem of location.
As shown in Figure 2, the sidepiece locator comprises the first locator 500, and this first locator 500 is slidably disposed on described the first longeron 301, for the top of the side to described automobile body, positions and clamps.The first locator 500 is arranged on the first longeron 301 of extreme higher position, thereby is convenient to position and clamp operation to the top of the side of automobile body.Common the first locator 500 is a plurality of, and as shown in Figure 3, but the present invention does not get rid of the situation of using first locator 500 yet.
In order to obtain good flexibility manufacture, the first locator 500 is slidably disposed on the first longeron 301 as mentioned above, thereby can move back and forth along the longitudinal direction of the first longeron 301 (being the length direction of automobile body to be processed).Specifically, when the length of automobile body to be processed is relatively grown, the first locator 500 on the first longeron 301 can be distributed to obtain relatively and disperse, to be adapted to the automobile body that length is long; And when the length of automobile body to be processed relatively in short-term, can distribute the first locator 500 on the first longeron 301 relatively concentrated, to be adapted to the shorter automobile body of length.
Hence one can see that, by making the first locator 500, is slidably disposed on the first longeron 301, can carry out frock processing to the automobile body of large scale scope more, thereby obtain good flexibility.
In addition, even if for the frock processing of same automobile body, by the first locator 500 is slidably disposed on the first longeron 301, can adjust at any time as required the position of the first locator 500, and then can obtain to locate preferably and clamp effect, thereby improve the quality of frock processing.
The sidepiece locator also comprises the second locator 600, and this second locator 600 is slidably disposed on the second longeron 302 lower than the first longeron 301, for the middle part of the side to described automobile body, positions and clamps.
The set-up mode of the second locator 600 and the first locator 500 is similar, and namely the second locator 600 is slidably disposed on the second longeron 302, obtains equally flexibility preferably.In addition, for same automobile body, by making the second locator 600, be slidably disposed on the second longeron 302, can obtain to locate preferably and clamp effect, thereby improve the quality of frock processing.
The sidepiece locator also comprises that the 3rd locator 700, the three locators 700 are arranged on the 3rd minimum longeron 303 of position, for the bottom of the side to described automobile body, positions and clamps.
The 3rd locator 700 can be similar to the first locator 500 and the second locator 600 and be slidably disposed on the 3rd longeron 303.But preferably, the 3rd locator 700 is along the total length setting of the 3rd longeron 303, thereby can not be slidably disposed on the 3rd longeron 303.This will be described hereinafter.
Above-mentioned the first locator 500, the second locator 600 and/or the 3rd locator 700 can be respectively traditional locator, as long as can realize locating the effect of clamping.For example, the first locator 500, the second locator 600 and/or the 3rd locator 700 can be the locators that comprises traditional hydraulic clamp, air clamper or hand actuable clamping device.
In the preferred case, as shown in Figure 5, the first locator 500 comprises the first noumenon 501 and the first clamping device 502, described the first noumenon 501 is slidably disposed on described the first longeron 301, but described the first clamping device 502 broad ways are slidably disposed on described the first noumenon 501.
The width at the top of automobile body sometimes can be less than the width of automobile body middle part or bottom, and for this vehicle, preferably, the first position of locator 500 on width is adjustable.Specifically the first noumenon 501 with reference to figure 5, the first locators 500 is slidably disposed on the first longeron 301 by draw-in groove 503.Realize that the first clamping device 502 that clamps and locate is arranged on the first noumenon 501 movably, specifically, the first clamping device 502 is provided with the chute (not shown), and on the first noumenon 501, be provided with the guide rail 504 that broad ways is extended, the first clamping device 502 is arranged on the guide rail 504 of the first noumenon 501 by its chute, thereby realizes the slidably setting of the first clamping device 502 with respect to the first noumenon 501.In addition, between the first clamping device 502 and the first noumenon 501, can be provided with stopping means, as spacer pin.
Therefore, the first clamping device 502 for the first locator 500, not only can be along with the first noumenon 501 moves along its length, can also move with respect to the first noumenon 501 broad ways, thereby can both meet the requirement of flexibility processing and manufacturing in the longitudinal direction with on width.
The first clamping device 502 can be traditional positioning clamping device, as air clamper (as shown in Figure 5), hydraulic clamp or hand actuable clamping device.
As mentioned above, the first locator 500 is mainly used in positioning and clamp operation to the top of the side of automobile body, under preferable case, the locator of the first locator 500 for positioning and clamp for the window pillar to described automobile body, therefore, the first locator 500 can be described as the window pillar locator in this case.
