Description
Technical field
The invention belongs to auto parts and components processing unit (plant) technical field, and in particular to a kind of thin wall special-shaped part flange face processing
Fixing device.
Background technology
With technological progress, industry development, product quality requires more and more higher.Core part as I. C. engine
One of exhaust manifold, its inlet flange flatness（Drawing）It is required that constantly lifting, particularly some external drawings, early stage
Drawing requirement flatness in 0.3mm → 0.25mm, after develop into 0.2mm → 0.15mm, in the recent period many drawings all mark 0.1mm →
0.05 flatness；Some is even more small.With Product Precision requirement continuous lifting, the continuous renewal of process equipment, product
Processing efficiency gradually reduces, quality cost gradually rises, and the profit margin of the product brought is less and less；Plus domestic overall row
The overall situation that industry glides, enterprise are faced with crisis of survival.
A kind of thin-wall aluminum alloy cover flange disk ring seam fixture for laser welding is disclosed in the B of CN 103831571, it is related to
A kind of and weld jig.The present invention stitches the exclusive clamps of laser welding for solution currently without thin-wall aluminum alloy cover flange disk ring
The problem of tool, causes welding deformation big, and weld seam precision can not meet welding requirements.Interior platen is located at the upper surface of interior platen seat
On, the first circular central groove is correspondingly arranged up and down with the second circular central groove, along circle on the upper surface of interior platen seat outer
Circumferential direction is machined with first annular groove；The second annular groove is along the circumferential direction machined with the lower surface of external pressure plate inner ring, outside
Second annular groove of platen is pressed together on first annular groove, and annular gap is left between external pressure plate and interior platen, multiple be hinged
Seat is along the circumferential direction fixedly arranged on the outer of lower disc, and the lower end of each screw rod is hinged with a corresponding hinged seat, often
The upper end of individual screw rod is connected through the outer of external pressure plate with second nut thread；
A kind of numerical control milling tool of thin-walled conical part, including a ring flange are disclosed in the U of CN 204935184,
There is a step at the edge of ring flange, and the cylinder of step and conical part is suitable for reading to be engaged, and a cylinder, cylinder are arranged at ring flange top
Top is a round flat board, and ring flange, cylinder and circle flat board are concentric, there is several L being evenly arranged in ring flange bottom
Shape support block, screw rod is fixed with each L shapes support block, L shape support blocks is connected with ring flange by nut and screw rod, L
The front end of shape support block and the step of flange plate edge can be by the clampings suitable for reading of the cylinder of conical part by screw rod and nut.But
Above two scheme does not possess stronger versatility, it is impossible to meets applicant to product inlet flange planarity requirements：It is overall
Flatness is 0.06mm, and the flatness in the range of 50x50 is 0.03mm.Because product belongs to thin wall special-shaped part, workpiece positioning,
Clamping is difficult.It is that can not meet product quality requirement according to existing processing unit (plant) and processing technology, being badly in need of one can meet
Product quality requirement, and can reduce the solution of product quality cost.
By the analysis to existing apparatus, obtaining the basic reason of problem is:
A. fixing device is excessive to workpiece active force, causes workpiece to deform, and after workpiece is removed material, flatness is overproof.
B. the active force that fixing device is fixed to workpiece is too small, and workpiece, because active force is big, causes work when removing material
Part loosens, and flatness is overproof after making workpiece removal material.
C. because workpiece is deteriorated, the power for the stress point that formation fixing device is fixed for workpiece is unbalanced, makes workpiece
Produce stress and concentrate deformation or the too small loosening of unbalance stress；After removing material, planeness of workpiece is overproof.
D. system operatio is complicated, and productivity ratio is low.
The key point of inventive problem is established in analysis more than having passed through：
A. when workpiece is fixed in fixing device, active force controllability of the fixing device to workpiece；
B. when workpiece is fixed in fixing device, fixation of the fixing device to workpiece is, it is necessary to eliminate due to workpiece variation
The force localization and active force deficiency problem brought;
C. when workpiece is fixed in fixing device, simple operation.
