Description
Technical field
The fixture of a kind of processing thin-walled lining of the present invention, relates to field of machining.
Background technology
In conventional mechanical processing, often can encounter and need to process some products not easily processed.Such as encounter sometimes and need processing non-turning body part on lathe, or milling machine is processed ultra-thin part, be not only not easily installed, also not easily ensure precision.These are all the problems of having a bad headache, and for thin wall component, being installed is a difficult point, is also key point.In actual processing, the mode that is installed is not right, and can cause very large impact to product, be installed tension, can cause distortion, and be installed pine, then can not good positioning workpieces, may have movement in process.
Summary of the invention
In order to overcome above-mentioned technical problem, the invention provides a kind of fixture of processing thin-walled lining, process specific lining part time, be out of shape during clamping little, positioning precision is high, easy to operate.
The technical scheme that the present invention takes is:
A kind of fixture of processing thin-walled lining, comprise base, base offers T-slot, be provided with T-shaped bar in T-slot, the upper plane of base is provided with lining, and lining top planes is provided with platen, screw rod one end is connected with the screwed hole on T-shaped bar, screw rod other end coupling nut, nut is positioned at the medial plane of platen, and the inner side plane of platen compresses lining.
Pad is provided with between described nut and the medial plane of platen.
The middle of described T-shaped bar offers screwed hole.
The depth of parallelism of upper and lower two planes of described base is 0.05mm, and flatness is 0.05mm.
Described base wall thickness is 20 ~ 30mm, alleviates quality as far as possible, makes rotary inertia minimum, adds man-hour requirement chuck centering grip base.
Be provided with gap between described base and T-shaped bar, conveniently assemble and disassemble, the required precision of the T-slot of T-shaped bar and base is processed according to professional standard.
Described platen is circular,
Described platen offers two symmetrical U-shaped through holes.
The fixture of a kind of processing thin-walled lining of the present invention, can use chuck to carry out grip base very easily, and centering is convenient, is particularly suitable for processing thin-walled lining on vertical lathe.This turning attachment has that structure is simple, mounting or dismounting are convenient, overcome bias, the life-span is long, working (machining) efficiency advantages of higher, the processing thin-walled lining part of particularly suitable.
Accompanying drawing explanation
Fig. 1 is the overall perspective view of fixture of the present invention;
Fig. 2 is the decomposition texture schematic diagram of fixture of the present invention.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of fixture of processing thin-walled lining, comprise base 1, base 1 offers T-slot, is provided with T-shaped bar 2 in T-slot, the upper plane of base 1 is provided with lining 4, lining 4 top planes is provided with platen 5, and screw rod 3 one end is connected with the screwed hole on T-shaped bar 2, screw rod 3 other end coupling nut 7, nut 7 is positioned at the medial plane of platen 5, is provided with pad 6 between described nut 7 and the medial plane of platen 5.The inner side plane of platen 5 compresses lining 4.
The middle of described T-shaped bar 2 offers screwed hole.Upper and lower two planes of described base 1 have parallel requirement.The depth of parallelism of two planes is 0.05mm, and flatness is 0.05mm.Described base 1 wall thickness is 20 ~ 30mm, alleviates quality as far as possible, adds man-hour requirement chuck centering grip base.Described platen 5 is circular, and size need be determined according to the actual processing of the lining 4 external diameter size that puts in place, lining 4 external diameter is processed and is not affected.Described platen 5 offers two symmetrical U-shaped through holes 8, be conveniently installed and regulate the position of platen 5 and screw rod 3.
When after screwing bolts, just lining 4 can be fixed on base 1 by platen 5, conventional clamping means are radial clamping, be easy to distortion, what adopt now is axial grip mode, like this can well controlling distortion, then centering grip base 1 is carried out by chuck, just can start processing, the method is practical is not very large with endoporus, is not easy to separately to join independent pressing plate and carrys out processing excircles in endoporus direction.After processing cylindrical, if need to process endoporus, only need separately to join platen 5, screw rod 7 and T-shaped bar 2 fitted shaft to being pressed in cylindrical top to process.
T-shaped bar 2 and base 1 should leave the gap of monolateral 1mm, conveniently assemble and disassemble, the required precision of the T-slot of T-shaped bar 2 and base 1 is processed according to professional standard, place T-shaped bar 2 when cross T-slot on base 1 is and is convenient to processing endoporus, T-shaped bar 2 coordinates screw rod 3 and platen 5 to fix lining 4 at bushing outer.Platen 5 is circular, and size need be determined according to the actual processing of the Outer Diameter of lining size that puts in place, lining 4 external diameter is processed and is not affected.Platen 5 has two symmetrical U-shaped through holes 8.One is can weight reduction, and two is the position of adjusting screw(rod) 3 easily to make platen 5 concentric with lining 4.
When lining 4 is axially fixed on base 1, lining 4 should be made as far as possible concentric with base 1, otherwise can bias be caused, machining accuracy can be decreased.
