Description
Technical field
The utility model relates to a kind of drilling tool, especially relates to a kind of drive axle axle housing brill and attacks Chinese lute hole upset frock, belongs to mechanical field.
Background technology
The drive axle flange face need be processed more hole, is that Line To Line spitting drill template is drawn in the Chinese lute hole to the basic employing one of this flange face boring processing at present, processes with radial drill; The 2nd, with Ni Zhifu drill processing,, be difficult to satisfy the requirement of flange hole location because product orientation reference dimension and frock self poisoning error are excessive, accuracy is very low, and manufacturing cost is very high.
The utility model content
At the deficiency that prior art exists, technical problem to be solved in the utility model is, provides a kind of drive axle axle housing to bore and attacks Chinese lute hole upset frock, and accuracy is very high, and has reduced manufacturing cost, steps up reliable.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is, a kind of drive axle axle housing bores attacks Chinese lute hole upset frock, comprises base, and described base two ends all are provided with an adjustable column, and adjustable column is provided with alignment pin; Two adjustable column inboards are provided with switching mechanism on the described base.
Optimize, above-mentioned drive axle axle housing bores attacks Chinese lute hole upset frock, and its switching mechanism comprises balancing weight and positioner, and balancing weight is connected by axle with positioner.
Optimize, above-mentioned drive axle axle housing bores attacks Chinese lute hole upset frock, and its positioner comprises movable pressing board, connects bore template by bolt on the movable pressing board, and bore template is provided with the centralized positioning dish of place work piece; The briquetting and the bolt of fixation workpiece are set on the centralized positioning dish; Described movable pressing board away from an end of balancing weight be provided with adjustable column on the suitable locating hole of alignment pin.
Optimize, above-mentioned drive axle axle housing bores attacks Chinese lute hole upset frock, also is provided with V shape iron on its center positioning disk.
The utility model provides a kind of frock clamp that uses radial drill processing flange hole, and this frock clamp can be realized the accurate boring of the big flange face of axle housing, applicable to the processing of parts of the same race, and is applicable to imitateing or using with type component.Reach accurate location simultaneously, stepped up reliable effect; Fix with movable pressing board before the frock upset, easy to use; Accurately locate with the alignment pin location frock upset back; Drive axle adopts movable block in two side compressions, can adapt to irregular surface and clamp requirement; Bushing plate and big flange seam centralized positioning dish connect as one, and have guaranteed the position degree of boring; The eccentric design of balancing weight can realize the convenient upset of frock, alleviates labor strength.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation before the utility model upset;
Fig. 2 is the structural representation after the utility model upset.
The specific embodiment
As depicted in figs. 1 and 2, the utility model is that a kind of drive axle axle housing brill is attacked Chinese lute hole upset frock, comprises base 10, and described base 10 two ends all are provided with an adjustable column 11 and 12, and adjustable column 11 and 12 is provided with alignment pin 13; Two adjustable columns 11 and 12 inboards are provided with switching mechanism 16 on the described base 10.Its switching mechanism 15 comprises balancing weight 1 and positioner 7, and balancing weight 1 is connected by axle with positioner 7.Its positioner 7 comprises movable pressing board 6, connects bore template 4 by bolt on the movable pressing board 6, and bore template 4 is provided with the centralized positioning dish 5 of place work piece 8; The briquetting 2 and the bolt 9 of fixation workpiece 8 are set on the centralized positioning dish 5; Described movable pressing board 6 away from an end of balancing weight 1 be provided with adjustable column on the suitable locating hole 14 of alignment pin 13.Also be provided with V shape iron 3 on its center positioning disk.With the big flange face in centralized positioning dish 5 location, spindle nose V shape iron 3 location in both sides utilize movable holddown 2 supported flange both sides, unclamp movable pressing board 6, make the axle housing upset back that puts in place insert locating holes 14 location with alignment pin 13, use the radial drill processing of holing.
In order to reach the purpose of design of above-mentioned frock clamp, the technical solution of the utility model when considering the attention aspect of this type of jig Design in the past emphatically from 3 considerations: the one, consider that from accurate location this just needs the frock can be with the flange face location and the processing of can overturning; The 2nd, from the easy to operate consideration of workpiece, need to increase counter weight device; The 3rd, to step up the surface irregularity needs and will add compact form and be designed to activity and compress in order to adapt to.Compress behind the location with spindle nose and big flange face, seam, saved the troublesome operation of previous line, location alignment, improved the positioning accuracy of product; Adopt the adjustable v-type iron that floats, boring, the tapping in applicable existing 485 all axle housing Chinese lute holes; Adopt movable bushing plate, same station can be realized boring and tapping processing; Get final product levelling after the axle housing upset, simple to operate, quick; Can easily realize the axle housing upset after adding balancing weight;
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
