Abstract
A drum / disk cutting machine for automobile brake, an axial cutting feed transmission of which adopts a friction transmission; the friction face of a friction wheel is a taper face; the center distance between the friction wheel and a friction disk is steplessly changeable, which realizes the stepless adjustment of the axial cutting feed. A direct mount of the brake drum / disk uses a general spherical surface locating sleeve, each of which is applicable to the brake drum / disk with an inner hole in a certain range. Two landscape orientation cutter bodies can be blocked on a horizontal cutter bracket of the cutting brake disk at one time to realize the simultaneous cutting of both sides of the brake disk.
Description
Affiliated technical field
The utility model relates to a kind of motor vehicle repair special equipment.
Background technology
At present, the axial feeding of automobile brake drum/dish cutter commonly used all is that classification is regulated, and the mount of brake drum/dish uses special-purpose location tapered sleeve, and the cutting of brake disc is the single face cutting.
Summary of the invention
The cutting of using special-purpose location tapered sleeve and brake disc for the mount of the classification adjusting of the axial feeding that overcomes automobile brake drum/dish cutter, brake drum/dish as the single face cutting with inconvenience, the utility model provides a kind of automobile brake drum/dish cutter, the axial feeding of this machine be the mount of step-less adjustment, brake drum/dish use the cutting of general sphere positioning sleeve and brake disc be two-sided simultaneously the cutting.
The technical scheme that its technical problem that solves the utility model adopts is: frictional drive is adopted in the axial feed transmission, and the rubbing surface of friction pulley is a taper seat, and the centre-to-centre spacing of friction pulley and frictional disk is stepless variation, thereby has realized the step-less adjustment of axial feed.The mount of brake drum/dish uses general sphere positioning sleeve, and each sphere positioning sleeve is applicable to the brake drum/dish of endoporus in certain limit.Two the horizontal cutter hubs and then the two-sided cutting simultaneously of realization brake disc simultaneously can be installed on the cross-slide of cutting brake disc.
The beneficial effects of the utility model are can improve the machining accuracy of brake drum/dish, more convenient operation.

The specific embodiment
In Fig. 3 and Fig. 4, rotating helical axis (12) drivening rod (13) rotates, connecting rod (13) drives frictional disk (10) by little axle (11) and moves, and makes the stepless variation of centre-to-centre spacing of frictional disk (10) and friction pulley A (8) and friction pulley B (9), thereby realizes the step-less adjustment of axial feed.
At Fig. 5, Fig. 6., among Fig. 7 and Fig. 8, turning handle (20) drives feed screw rod (19) and moves axially, because laterally cutter hub (16) is hung over the pulling force of the spring (18) on the screw (17) all the time, thereby laterally the tail end of cutter hub (16) contacts with the head of feed screw rod (19) all the time, and promptly laterally the position of cutter hub (16) changes along with moving axially of feed screw rod (19).Owing to go up symmetry the horizontal cutter hub of two covers parts such as (16) is installed, thereby can be realized the two-sided cutting simultaneously of brake disc at cross-slide (14).
In Fig. 9, platen (23), spring (26), sphere positioning sleeve (24), brake disc (25), platen (23), spacer (22) and locking nut (21) are contained on the axle (1) successively, and screwing locking nut (21) can be with the reliable chucking of brake disc (25).
Claims (3)
1. automobile brake drum/dish cutter, the axial feed transmission is a frictional drive, it is characterized in that: the rubbing surface of friction pulley is a taper seat, the centre-to-centre spacing of friction pulley and frictional disk is stepless variation.
2. automobile brake drum according to claim 1/dish cutter is characterized in that: the mount of brake drum/dish uses the sphere positioning sleeve.
3. automobile brake drum according to claim 1/dish cutter is characterized in that: two horizontal cutter hubs simultaneously can be installed on the cross-slide of cutting brake disc.
