Description
Technical field
The present invention relates to a kind of processing method of heavy automobile two-segment drive bridge oil seal seat, belong to the auto parts machinery technical field.
Background technology
The double-section drive axle oil seal seat is the important seal in a kind of heavy bearing automobile product newly developed, in case this part failure, can cause drive axle internal gear, bearing etc. to lose oil, aggravate component wear and early stage the damage, in a single day lubricating oil flow in the hub reduction gear simultaneously, causes the hub reduction gear oil level to raise, wash out oil sealing, flow in the brake drum, cause poor stop, jeopardize safe driving.In the prior art, in order to satisfy the requirement that vehicle bridge promotes, the seal request height, Element Design is comparatively complicated, clamping process is more yielding during fine finishining, the axiality of the perpendicularity of endoporus and end face, endoporus and cylindrical requires comparatively strict, and the cylindricity of the dimensional accuracy in hole, cylindrical require also higher, the difficult control of form and position tolerance.
Summary of the invention
At the deficiencies in the prior art, the invention provides an a kind of cover processing method, to ensure the machining accuracy and the specification requirement of drive axle oil seal seat to the drive axle oil seal seat.This technology work in-process adopts the rough turn and chamfering of CA6140, and CK50 numerically controlled lathe finish turning end face, endoporus and cylindrical, M1432B grinding machine adopt special-purpose mill folder processing excircles and end face, guarantee cylindrical and end face surface roughness.
Processing step of the present invention is as follows:
1, determines the equipment that processing is required, blank drawing;
2, the equipment that uses according to processing designs the positioning fixture of each operation and required dedicated tool;
3, be benchmark with workpiece rear end face and half cylindrical, with the rough turn front end face of CK50 numerically controlled lathe and second half cylindrical;
4, the front end face that will process and second half cylindrical are benchmark, with the rough turn rear end face of CK50 numerically controlled lathe and half cylindrical, and the control Workpiece length;
5, with excircle of workpiece heat treatment, surface high frequency Quenching Treatment, depth of quenching 1.5-1.9mm, hardness HRC50-55;
6, be benchmark with workpiece rear end face and cylindrical, with CA6140 lathe recessing, and chamfering;
7, be benchmark with workpiece rear end face and cylindrical, with two inner planes and endoporus in the middle of CK50 numerically controlled lathe and the dedicated tool finish turning;
8, with the workpiece inner hole sleeve on the special purpose grinder anchor clamps, with a workpiece endoporus and an inner plane is benchmark, behind nylon spacer of another inner plane direction pad, adopt rational thrust with Work-sheet pressing, with M1432B grinding machine processing excircles, control outer round surface roughness and cylindricity, and middle two parallel planes and cylindrical perpendicularity;
9, cleaning, deburring, oil antirustly, put into dedicated stream and change trains or buses, warehouse-in.
The present invention adopts definite use equipment, conutersigns drawing together with forge plant, and design specialized anchor clamps and cutter are from the machining angle of workpiece, for satisfying end face and outer round surface roughness, prevent clamping deformation, adopt the nylon spacer damping, and guarantee that clamping is solid and reliable, guarantee designing requirement; As not adopting nylon spacer, can cause workpiece datum level and anchor clamps loose contact during clamping, workpiece deformation can't satisfy cylindrical cylindricity and surface roughness, and endoporus and outer circles; Cylindrical heat treatment: the surface high frequency Quenching Treatment, depth of quenching 1.5-1.9mm, hardness HRC50-55 is hardness and the wearability in order to increase this face, improves the service life of product.The parts that use the present invention to produce have reduced frictional force, have very high sealing property, and oil consumption simultaneously is few, energy-conservation; Utilize the present invention to have production efficiency height, quality assurance, low cost and other advantages.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing:
Among the figure 1, cylindrical A 2, cylindrical B 3, rear end face 4, front end face 5, inner plane D6, inner plane G 7, endoporus
The specific embodiment
Embodiment: as shown in drawings, the concrete processing step of processing drive axle oil seal seat is as follows:
1, according to the size of workpiece, precision, selection equipment is when having determined production drive axle oil seal seat: engine lathe, numerically controlled lathe, these three kinds of equipment of grinding machine, with forge plant countersign blank drawing, determine blank forging requirement and roughing benchmark;
2,, design the processing scheme and the frock clamp of each procedure, and determine to use the specifications and models of cutter according to the workpiece hardness after handling according to process equipment and workpiece requirement;
3, be benchmark with workpiece rear end face 3 and half cylindrical A1, clamp that at CK50 numerically controlled lathe get on the bus front end face 4 and second half cylindrical B2, this moment, processing dimension must be considered the amount and the grinding allowance of quenching distortion in the future with claw;
4, the front end face 4 that will process and second half cylindrical B2 are benchmark, with the rough turn rear end face 3 of CK50 numerically controlled lathe and half cylindrical A1, control the Workpiece length size simultaneously and reach the drawing requirement, the cylindrical processing dimension also must be considered the amount and the grinding allowance of quenching distortion in the future, and the amount of cylindrical A1, two sections cylindrical quenching distortions of cylindrical B2 is different;
