When 114 completion of processing of screw hole 115 and tooth socket, bending side 17 is processed, since bending side 17 is by multiple angles Different planes are connected in sequence, and in order to facilitate feed, in processing, centered on the axis of bar, rotation bar makes Each plane of bending side 17 is sequentially located at horizontal position, then is processed using milling tool, and in processing, first processing is close to second The face of hollows 18, then successively milling to the right, ultimately form bending side 17, after bar turns to respective angles, milling cutter Cutting line can be to be processed from front to back, one face of one-pass molding;Due to milling as far as possible at milling upper surface 16 The clout above part is reamed, therefore can also be processed from right to left, extra defective material, adds to all planes above cutting workpiece After work finishes, bending side 17 can be formed.So far the plane above part is machined finishes.
After 17 completion of processing of bending side, from feed on bending side 17, it is drilled with counterbore 116, drilling behaviour is carried out to workpiece Make, before drilling, workpiece turned into respective angles, by the axis trimming of counterbore 116 to horizontal position, first uses milling cutter, From feed on bending side 17, the head of counterbore 116 is processed, milling cutter milling from left to right forms the head (macropore) of counterbore 116, After milling cutter completion of processing, then drill bit is used to drill through 116 head of counterbore, form the tail portion (aperture) of counterbore 116, completes counterbore 116 Processing.Counterbore 116 is adjusted to feed again behind horizontal position, can be convenient drill bit and milling cutter calibration and processing, especially Drill bit in drilling, drill bit with the bottom surface on 116 head of counterbore be it is vertical, avoid drill bit from occurring deviating or fracture, guarantee The angle of counterbore 116 and the precision of part.
Next S3 is entered step, bar is flipped up 90 °, at this point, front arc 12 is arranged upward, using milling tool Front end face 11 is processed, due to having adjusted part position, the tool path pattern of milling cutter is very flexible, and milling cutter can from right to left, can also With feed from front to back, feed mode is very flexible.
After 11 completion of processing of front end face, S4 is entered step, bar is rotated centered on bar axis, bar is rotated 180 °, at this point, lower end surface 110 and 16 location swap of upper surface, using round nose slotting cutter, directly where the left side of workpiece 14 Side feed, to bar carry out milling, using round nose slotting cutter process, round nose slotting cutter can be with one-pass molding lower end surface 110 And lower camber side 111, reduce manufacturing procedure.
Bar is then rotated again, right side 15 to be processed is turned into horizontal position, using milling cutter, Milling Process shape At right side 15, bar is resetted after completion of processing.
Step S5, cutting, along part left and right directions, cuts off semi-finished product with milling cutter, by semi-finished product and bar Separation cuts off workpiece using milling cutter, and bar does not need to rotate, ensure that cutting precision, avoid causing workpiece in cutting-off process Damage.In cutting, at least machining allowance of 1mm is reserved at the rear end face 19 of part, both can be convenient subsequent polishing in this way Part forms rear end face 19, and can reduce bar loss, avoids the occurrence of wasting phenomenon.
Material residual is often had due to just cutting the piece surface finished, in order to guarantee the machining accuracy of rear end face 19, After cutting parts, prerinse is carried out to workpiece, part is put into cleaning machine and is cleaned, after prerinse finishes, into Enter step S6.
Step S6, again clamping clamp upper surface 16 and lower end surface 110, and when clamping is noted that connecing for clamping jaw and part Touching position needs to avoid 112 position of strip groove, also, after clamping, lower end surface 110 is arranged upward, facilitates subsequent add Work strip groove 112.The then section of the part in polishing step S5, forms rear end face 19, finally, using milling tool shaping Shape slot 112 and third hollows 113, complete the processing of part.
After part excision forming, it is also necessary to carry out secondary cleaning to part, remove in step S6 and remain in piece surface Cutting clast, part is put into cleaning machine, is cleaned again, after cleaning, processing is passivated to part, to improve zero The corrosion resistance of part.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this All by the protection of Patent Law in the scope of the claims of invention.
