Abstract
A hydraulic brake of a machine tool rotating C-axis belongs to a machine tool composition device. The traditional braking way, such as brandish braking, lock braking and end face braking, etc, has the shortcomings, such as insufficient brake torque, not sensitive braking action and poor braking reliability, etc. The utility model comprising a coupling flange and a expanded coupling sleeve is characterized in that the coupling flange tightly coats the lateral wall of the expanded coupling sleeve and is mutually fixed with the expanded coupling sleeve and a closed oil cavity connected with a hydraulic circuit forms between the coupling flange and the expanded coupling sleeve. The expanded coupling sleeve forms an elastic braking part at a position corresponding to the closed oil cavity. The oil pressure in the closed oil cavity forces the elastic braking part of the expanded coupling sleeve to be deformed and inner dumped to clamping or loosening the bearing sleeve mutually fixed with the rotating C-axis, completing the braking function of the rotating C-axis. The utility model is simple and compact in structure, quick and sensitive in action and low in cost, realizing the large torque braking of the rotating C-axis.

Background technology
Five Double swing head lathe rotation C spindle unit claimed structure compactnesses, it is little to take up room, to realize the bigger range of work, also require bigger brake weight to refuse and brake sensitivity faster to brake gear, can be fast to adapt to when the high-rate cutting, reliablely and stablely rotation C axle is played braking action.Traditional brake modes as drum stop, brake holding, end face are stopped etc. all can't realize above-mentioned requirements.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is exactly to overcome defective such as the sensitive inadequately and brake poor reliability of brake torque deficiency, brake that prior art exists, provide a kind of simple and compact for structure, volume is small and exquisite, rapid sensitive has the high-accuracy lathe rotation C axle braking device that big brake weight is refused.For this reason, the utility model is by the following technical solutions:
Lathe rotation C axle fluid brake, comprise tie-plate and swelling cover, it is characterized in that described tie-plate closely is coated at the outer wall of described swelling cover and interfixes with described swelling cover, form airtight oil pocket between the two, described swelling puts the position corresponding with this airtight oil pocket and forms elasticity brake portion.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Rounded cover tubular is overlapped in described swelling, and its outer wall is provided with groove, and described elasticity brake portion is formed on the bottom of this groove; Described tie-plate is the cylindrical shroud tubular; Thereby form described airtight oil pocket by described groove.
Described swelling cover adopts the spring steel manufacturing.
Described swelling cover is made up of fixed part and operate portions two parts, and the fixed part external diameter makes whole swelling cover outer wall be step-like greater than the external diameter of operate portions, and fixed part and operate portions junction form step end face, and described groove is arranged on the operate portions outer wall.
One end end face of described tie-plate is provided with at least two axial screws that along the circumferential direction are evenly distributed, described step end face is provided with corresponding with it axial step through hole, described end face and described step end face adjacency, be screwed into screw after passing step through-hole with trip bolt, with described swelling cover and tie-plate is done axially and circumferencial direction is fixed.
The swelling cover operate portions outer wall of described groove both sides is provided with seal groove, is provided with O-ring seals in the seal groove, is used for seal oil chamber is played the enhanced leaktightness effect.
The utility model is installed in the rotation C spindle unit, the tie-plate terminal pad of connecting with rotation C axle behind the stator of servomotor device is fixedly connected, the swelling cover is coated at the bearing holder (housing, cover) that interfixes with rotation C axle in the series connection servomotor device, swelling cover internal diameter is greater than the bearing holder (housing, cover) external diameter, and swelling cover and bearing holder (housing, cover) can relatively rotate.During work, hydraulic oil pump is pressed into airtight oil pocket with hydraulic oil, increase the hydraulic pressure in the airtight oil pocket, prominent in the elasticity brake portion distortion of compressing swelling cover operate portions, make swelling cover and bearing holder (housing, cover) form interference fit, thereby block bearing holder (housing, cover), rotation C axle can't be rotated again, realize braking action rotation C axle.Hydraulic oil in airtight oil pocket reduces, and after the pressure cancellation, the elasticity brake portion of swelling cover operate portions resiles, and can relatively rotate again with bearing holder (housing, cover), makes the rotation C axle again can operate as normal.
Hydraulic pressure in the airtight oil pocket is big more, and the elasticity brake portion distortion of swelling cover is big more, and is also just big more to the clamping force of bearing holder (housing, cover), refuses also just big more to the brake weight of rotation C axle.So, just can realize the performance of high pulling torque brake as long as reasonably increase the interior hydraulic pressure of airtight oil pocket.
The utlity model has following beneficial effect: this brake gear is simple and compact for structure, the action rapid sensitive, and cost is lower, can realize the high pulling torque brake of rotation C axle.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises tie-plate 1, swelling cover 2, O-ring seals 3 and screw 5.
Tie-plate 1 is a cylindrical sleeve, and wherein an end end face 6 is provided with four axial screws 7 that along the circumferential direction are evenly distributed;
Tie-plate 1 closely is coated at the outer wall of the operate portions of swelling cover 2, make the described groove 8 and the inwall of described tie-plate 2 form airtight oil pocket 4, end face 6 and step end face 10 adjacency, step through-hole 11 is aimed at screw 7, screw 5 passes step through-hole 11 and is screwed into screw 7, tie-plate 1 and swelling cover 2 is done axially and circumferencial direction is fixed.
As shown in Figure 3, the utility model is installed in the rotation C spindle unit of lathe, be provided with hydraulic circuit and be communicated with airtight oil pocket 4 and machine tool hydraulic oil pump station, tie-plate 1 terminal pad 12 of connecting with rotation C axle behind the stator of servomotor device is fixedly connected, swelling cover 2 is coated at the bearing holder (housing, cover) 14 in the series connection servomotor device, swelling is overlapped 2 internal diameters greater than bearing holder (housing, cover) 14 external diameters, and swelling cover 2 can relatively rotate with bearing holder (housing, cover) 14, and bearing holder (housing, cover) 14 interfixes with rotation C axle.
