Abstract
The utility model relates to a hydraulic brake device which is equipped on the main spindle box of the machine, characterized in that the utility model comprises a rotating element fixed on the outer periphery of a rotation shaft, a connecting shelf fixed on the housing, a brake-block, a hydro-cylinder, and a plunger in the hydro-cylinder, wherein the rotating element and the brake-block are equipped with a thin-walled brake disc. The plunger, the brake disc of the brake-block, the brake disc of the rotating element, and the connecting shelf are sequentially distributed. The utility model has the beneficial effects of that the utility model achieves the brake effects by the pushing action of the plunger and through the elastic deformation produced by the thin-walled structure of the friction disk, and realizes the brake of a driving medium by using simple hydraulic equipment in the finite die cavity of the interior of the main shaft gearbox, thereby avoiding the problems of oversize and complicated structure of the housing due to the brake, effectively improving stationarity and reliability of the brake, and being particularly suitable for the driving and braking in the interior of a mill-head box of a numerically controlled fraise machine.
Description
(1) technical field
The utility model relates to a kind of hydraulic brake system.
(2) background technology
At present, some machine tool that uses in the mechanical processing industry is because the speed of mainshaft is fast, and moment of torsion is big, and inertia is big, cause the stationarity of skidding and reliability poor, and volume is big, and complex structure causes the main spindle box complex structure oversize.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provides that a kind of volume is little, the hydraulic brake system of good braking effect.
The utility model is achieved by the following technical solution:
Hydraulic brake system of the present utility model is arranged on the main spindle box of lathe, and its special character is: comprise the revolving part that is fixed on a rotating shaft excircle, be fixed on hitch, brake block, oil cylinder on the casing, be positioned at in-oil cylinder piston; Have the thin-walled brake(-holder) block on revolving part and the brake block; The brake(-holder) block of piston, brake block, the brake(-holder) block of revolving part, hitch, four distribute successively.
Hydraulic brake system of the present utility model, for good braking effect, long service life, the brake(-holder) block of hitch and brake block, the brake(-holder) block contact position of the two and revolving part is respectively arranged with friction piece.
Hydraulic brake system of the present utility model, for good braking effect, this device is the ring device around rotating shaft.
The beneficial effects of the utility model are, under the impetus of piston, the strain that thin-wall construction by friction plate produces reaches braking effect, in the limited die cavity of spindle drive box house, utilize comparatively easy hydraulic means to realize the braking of driving member, avoided the complicated oversize problem of the body structure that causes because of braking, and effectively improved braking stationarity and reliability, the milling head box house transmission that is specially adapted to CNC milling machine is stopped tightly.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is the structural representation in the utility model vertical section.
Among the figure, 1 revolving part, 2 hitch, 3 friction pieces, 4 brake block, 5 friction pieces, 6 pistons, 7 oil cylinders.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Hydraulic brake system of the present utility model is arranged on the main spindle box of lathe, comprises the revolving part 1 that is fixed on a rotating shaft excircle, is fixed on hitch 2, brake block 4, oil cylinder 7 on the casing, is positioned at in-oil cylinder piston 6; Have the thin-walled brake(-holder) block on revolving part 1 and the brake block 4; The brake(-holder) block of the brake(-holder) block of piston 6, brake block 4, revolving part 1, hitch 2, four distribute successively.The brake(-holder) block of hitch and brake block, the brake(-holder) block contact position of the two and revolving part is respectively arranged with friction piece 3,5.Whole device is the ring device around rotating shaft.
Hydraulic brake system of the present utility model is fixed on by screw in the milling head casing of CNC milling machine.Feeding hydraulic oil moves the piston 6 of annular, piston contacts with the brake(-holder) block of brake block 4 upper ends, because between brake block and the brake(-holder) block is thin-wall construction, transmit the increasing of power along with piston, micro-deformation takes place, cause the close and contact of its brake(-holder) block that friction piece 5 is housed to the brake(-holder) block of revolving part 1, the root of brake(-holder) block also is designed to thin-wall construction on the rotary body, this structure produces micro-strain simultaneously, the brake(-holder) block another side of rotary body is contacted with friction piece 3 on the link span 2, and the two sides of the brake(-holder) block of rotary body all contact with friction piece, and frictional force strengthens under the effect of piston, rotary body is clamped, reaches the purpose of braking revolving part.After the hydraulic oil release, the thin-wall construction strain of rotary body 1 and brake block 4 disappears, and friction piece and revolving part still keep the original interstice.
Claims (3)
