Description

The uniform adjustment method of benchmark of track passenger vehicle tooling

Technical field

The present invention relates to track passenger vehicle location or hold-down gear debugging technique field, it is specifically related to the uniform adjustment method of benchmark of a kind of track passenger vehicle tooling.

Background technology

The frock clamp of present workshop onsite application, only X-axis, Y-axis two benchmark, and no matter how greatly how complicated frock, only two lines in fixture datum, namely X-axis, Y-axis (as shown in Figure 1). Much complex large-sized frock, owing to locating device above, hold-down gear are a lot, a lot of position can't detect, and can only detect with 3D detector or ruling machine, and detect and debug, waste resource, delay normal production.

Summary of the invention

Only two reference lines existed to solve existing frock clamp need to use 3D detector or ruling machine to detect, and inefficient technical problem, the present invention provides the uniform adjustment method of benchmark of a kind of track passenger vehicle tooling.

The technical scheme that technical solution problem of the present invention is taked is as follows:

The uniform adjustment method of benchmark of track passenger vehicle tooling, comprises the steps:

The first step, two lateral fiducial blocks are set on the datum plate of tooling and two longitudinal reference blocks, respectively along two lateral fiducial blocks and two longitudinal reference blocks, datum plate is delineated cross centre line, the horizontal X-axis line that namely cross intersects and longitudinal Y-axis line;

2nd step, it is benchmark taking X-axis, according to the quantity of locating device needed for tooling on X-axis direction and the scantlings of the structure of each locating device, delineate many straight lines parallel with X-axis respectively to X-axis both sides in units of fixed range etc. spacing or unequal-interval, namely complete the delineation of X axis datum line;

3rd step, it is benchmark taking Y-axis, according to the quantity of locating device needed for tooling on Y-axis direction and the scantlings of the structure of each locating device, delineate many straight lines parallel with Y-axis respectively to Y-axis both sides in units of fixed range etc. spacing or unequal-interval, namely complete the delineation of Y axis datum line;

4th step, each Y axis datum line determined according to each X axis datum line determined by the 2nd step on tooling datum plate and the 3rd step, the position of locating device is debugged by operator respectively by benchmark of the X axis datum line nearest apart from locating device to be debugged and Y axis datum line.

The invention has the beneficial effects as follows: 1, change the problem that the existing frock always continued to use only has two reference lines. 2, benchmark is uniform, utilize nearest reference line debugging locating device, convenient debugging, the debugging instruments such as the seat chi of debugging have living space placement. 3, there is uniform benchmark, not only the accuracy of convenient checking frock clamp debugging, it is also possible to checking weldment group is to the accuracy of rear size. 4, changing in the past owing to the parts on fixture are various, plate chi can not skip the drawback that barriers is measured. 5, existing large-scale frock, initial failure period about 5 days, medium-sized frock initial failure period about 3 days, small-sized frock debugging about 1 day. After using this method, the debugging of large-scale frock can shorten two days, and the debugging of medium-sized frock can shorten one day, and the debugging of small-sized frock can shorten half a day. If all frock adopts this method manufacture, about more than 300 overlap the initial failure period about 500 days of frock saving every year.

Accompanying drawing explanation

Fig. 1 is the Tool clamp structure schematic diagram that existing reference line only has two.

Fig. 2 is that the present invention is by Tool clamp structure schematic diagram uniform for reference line.

Embodiment

Below in conjunction with drawings and Examples, the present invention is described in further details.

The uniform adjustment method of benchmark of track passenger vehicle tooling of the present invention comprises the steps: the first step, arranges two lateral fiducial blocks on the datum plate of tooling and two longitudinal reference blocks, respectively along two lateral fiducial blocks and two longitudinal reference blocks, datum plate is delineated cross centre line, the horizontal X-axis line that namely cross intersects and longitudinal Y-axis line; 2nd step, it is benchmark taking X-axis, according to the quantity of locating device needed for tooling on X-axis direction and the scantlings of the structure of each locating device, delineate many straight lines parallel with X-axis respectively to X-axis both sides in units of fixed range etc. spacing or unequal-interval, namely complete the delineation of X axis datum line; 3rd step, it is benchmark taking Y-axis, according to the quantity of locating device needed for tooling on Y-axis direction and the scantlings of the structure of each locating device, delineate many straight lines parallel with Y-axis respectively to Y-axis both sides in units of fixed range etc. spacing or unequal-interval, namely complete the delineation of Y axis datum line; 4th step, each Y axis datum line determined according to each X axis datum line determined by the 2nd step on tooling datum plate and the 3rd step, the position of locating device is debugged by operator respectively by benchmark of the X axis datum line nearest apart from locating device to be debugged and Y axis datum line.

As shown in Figure 2, for welding settings, fixture datum plate arranges two lateral fiducial blocks 1 and two longitudinal reference blocks 2, respectively along the longitudinal reference block 2 of two lateral fiducial blocks 1 and two, datum plate is delineated cross centre line as X-axis and Y-axis, take X-axis as benchmark, quantity according to locating device on fixture and structure size, a straight line is respectively delineated (such as to X-axis both sides respectively in units of 200mm and 500mm, X-axis (-200mm) reference line 5) so that on datum plate, X-axis direction has three X axis datum lines 3; Then, it is benchmark again taking Y-axis, quantity according to locating device on fixture and structure size, four straight lines are respectively delineated (such as to Y-axis both sides equally spacedly in units of 500mm, Y-axis (+1000mm) reference line 6) so that on datum plate, Y-axis direction has nine Y axis datum lines 4. After reference line is uniform, the position of locating device is debugged by operator respectively by benchmark of the X axis datum line nearest apart from locating device to be debugged and Y axis datum line, can save a lot of man-hour like this.

Adopt the uniform adjustment method of benchmark of the present invention, it is possible to shortening frock debugging cycle, it is qualified, easy to detect frock to be debugged with manpower, is the production saving time; With short production cycle at bogie, when vehicle is many, scheduling is nervous, the method has saved the use of 3D test set and ruling machine, substantially increases production efficiency.
