Abstract
The invention discloses a turning technology of a thin-walled sealing piece for rail transit. The thin-walled sealing piece for rail transit is formed in the mode that after a plurality of floating type jack catches are adopted on a numerical control lathe for one-time clamping, rough turning and finish turning are performed. In the rough turning process, an R0.4 circular bead blade is adopted, the back engagement of the cutting edge is 0.1-0.12 mm, the feeding amount is 0.04-0.05 mm/r, and 0.08-0.1 mm fine turning allowance is reserved on the outer circle and an inner hole; in the finish turning process, an R0.2 circular bead blade is selected, the back engagement of the cutting edge is 0.02-0.04 mm, and the feeding amount is 0.02-0.04 mm/r. Due to the mode, the problems that clamping of parts deflects and clamping deforms can be solved, and product precision and quality are improved.
Description
Technical field
The present invention relates to bearing mnanufacture technical field, particularly relate to a kind of Vehicle Processing technique of track traffic thin-walled seal.
Background technology
Bullet train requires to run under very strict condition of work, particularly radial, axial, under the condition that runs up, require the necessary high pressure resistant and rub resistance of high ferro locomotive seal, extend main frame No leakage normal working hours and maintain and replace cycle, and its function must be kept with reliability to greatest extent.Existing track traffic thin-walled seal, the impact of Vehicle Processing precision on the heat treatment deformation in later stage, mill machining accuracy, end product quality of lasso is very large before heat treatment, and serious scraps directly producing.Traditional Vehicle Processing technique adopts the clamping of three-point contact type claw, and when processing parts, do not position the axis of part, this can cause the axis of the axis and scroll chuck clamping rear part to exist crooked; And the form and position tolerance of part can be made to increase after the wearing and tearing of three-point contact type claw, processing thin-walled part can produce " rib circle ", affects product quality.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, provides a kind of Vehicle Processing technique of track traffic thin-walled seal, can solve the problem that part clamping is crooked, clamping is out of shape, improve Product Precision and quality.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the Vehicle Processing technique providing a kind of track traffic thin-walled seal, described track traffic thin-walled seal is adopt the floating type claw clamped one time of some covers on numerically controlled lathe after simultaneously, through rough turn-finish turning aft-loaded airfoil; Time rough turn, select R0.4 fillet blade, back engagement of the cutting edge is 0.1-0.12mm, and the amount of feeding is 0.04-0.05mm/r, and cylindrical and endoporus all stay the allowance of 0.08mm-0.1mm; During finish turning, select R0.2 fillet blade, back engagement of the cutting edge is 0.02-0.04mm, and the amount of feeding is 0.02-0.04mm/r.
In a preferred embodiment of the present invention, described floating type claw has three covers.
In a preferred embodiment of the present invention, often overlap on described floating type claw and contain two floating cushion blocks, make the periphery of bearing on floating type claw with six point contact type axial location of decile.
In a preferred embodiment of the present invention, the material of described track traffic thin-walled seal is SKF3 bearing steel.
The invention has the beneficial effects as follows: adopt the floating type claw clamping of many covers when Vehicle Processing, the periphery of product is made to adopt six point contact type axial location of decile, radial multiaspect clamping, and the amount of floating of floating type claw is controlled, the slight fluctuation in axis and radial direction can be realized, solve the problem that part clamping is crooked, clamping is out of shape, improve Product Precision and quality.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
A Vehicle Processing technique for track traffic thin-walled seal, the material of described track traffic thin-walled seal is SKF3 bearing steel, can improve life-span and the reliability of product, for the following process quality of product lays the foundation.Its Vehicle Processing technique comprises the steps: rough turn endoporus plane-rough turn outer disk-CNC finish turning endoporus plane-CNC fine turning outer circle plane.
During Vehicle Processing, first workpiece to be added clamping on numerically controlled lathe of track traffic thin-walled seal is fixed.During clamping, adopt the floating type claw of three covers simultaneously, often overlap on described floating type claw containing two floating cushion blocks, make the periphery of bearing on floating type claw with six point contact type axial location of decile, radial multiaspect clamping, and the amount of floating of floating type claw is controlled, the slight fluctuation in axis and radial direction can be realized, solve the problem that part clamping is crooked, clamping is out of shape.
Time rough turn, select R0.4 fillet blade, back engagement of the cutting edge is 0.1-0.12mm, and the amount of feeding is 0.04-0.05mm/r, and cylindrical and endoporus all stay the allowance of 0.08mm-0.1mm; During finish turning, select R0.2 fillet blade, back engagement of the cutting edge is 0.02-0.04mm, and the amount of feeding is 0.02-0.04mm/r.
The product ellipse processed controls at about 0.03mm, and parallel error controls at about 0.02-0.03mm.
Present invention is disclosed a kind of Vehicle Processing technique of track traffic thin-walled seal, the floating type claw clamping of many covers is adopted when Vehicle Processing, the periphery of product is made to adopt six point contact type axial location of decile, radial multiaspect clamping, and the amount of floating of floating type claw is controlled, the slight fluctuation in axis and radial direction can be realized, solve the problem that part clamping is crooked, clamping is out of shape, improve Product Precision and quality.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
