Abstract
The invention discloses a method for machining a casting of an automobile brake adjusting arm through 13mm drilling at a high speed. The method mainly includes the following steps that (1) at first, preparation for drilling and expanding a through hole fai of 12.8 mm and drilling an Rc 1 / 8 hole is carried out, and a Z3025 radial drilling machine and a high-speed steel drill are adopted for drilling; (2) secondly, the hole fai of 12.8 mm is drilled firstly, f=0.63 mm / r, and the real cutting speed is 38.68 m / min; (3) a hole fai of 13 mm is drilled and expanded, the cutting speed is set as 22 m / min, and the flexible working hour is 0.081 min. The method has the advantages that the casting can improve the brake stability degree and tensile strength, can bear vibration or impact, is suitable for mass production and low in cost and can be improved according to different vehicle models conveniently.
Description
Technical field
The present invention relates to automobile technical field, relate in particular to a kind of braking automobile and adjust the processing method that arm foundry goods high speed 13mm holes.
Background technology
Along with the progress of technology; the front brake of automobile is adjusted arm shell and is being brought into play more and more important effect; its Main Function is front brake to be adjusted to arm support and protect, and Ta center is a splined hole, and outside is worm-gear toothing; there is a worm shaft side; on head, have a four directions, adjust brake use, outermost has a hole; dress pin connects wheel cylinder, and hole and keyway and axle coordinate transmitting torque to reach the effect of adjusting brake.Foundry goods is wherein for supporting and protection front brake adjustment arm; also carry-over moment of while, therefore has some strength requirement to part, should possess certain tensile strength and can bear vibrations or impact; if these foundry goods are produced in enormous quantities, need lower cost.
Thereby, adjust the processing of arm foundry goods for front brake, particularly exist certain drawback for the high speed 13mm bore process of foundry goods, therefore, for above aspect, need to make effective innovation.
Summary of the invention
The object of this invention is to provide and a kind ofly improve brake degree of stability, can improve tensile strength, can bear vibration or impact, be applicable to the processing method produced in enormous quantities, the braking automobile being convenient to improve according to different automobile types is adjusted arm foundry goods high speed 13mm boring, to solve many deficiencies of prior art.
Object of the present invention is carried out specific implementation by the following technical programs:
Braking automobile is adjusted a processing method for arm foundry goods high speed 13mm boring, is mainly made up of following steps:
(1) first, prepare to bore, expand through hole φ 12.8mm, bore Rc1/8 hole, adopt Z3025 radial drilling machine, high-speed steel drill boring;
(2) then, subdrilling φ 12.8mm hole, f=0.63mm/r, actual cut speed 38.68 m/min;
(3) counterboring φ 13mm hole, cutting speed is set to 22m/min, flexible working hours 0.081min.
The beneficial effect that braking automobile of the present invention is adjusted the processing method of arm foundry goods high speed 13mm boring is: the foundry goods of producing by the method can improve brake degree of stability, can improve tensile strength, can bear vibration or impact, be applicable to producing in enormous quantities, cost is lower, is convenient to improve according to different automobile types.
The specific embodiment
Described in the embodiment of the present invention, braking automobile is adjusted the processing method of arm foundry goods high speed 13mm boring, is mainly made up of following steps:
(1) first, prepare to bore, expand through hole φ 12.8mm, bore Rc1/8 hole, adopt Z3025 radial drilling machine, high-speed steel drill boring;
(2) then, subdrilling φ 12.8mm hole, f=0.63mm/r, actual cut speed 38.68 m/min;
(3) counterboring φ 13mm hole, cutting speed is set to 22m/min, flexible working hours 0.081min.
Claims (1)
