Abstract
The utility model discloses a hydraulic locking device for a center frame and a body of a machine tool, which belongs to the field of equipment manufacturing. The device comprises the center frame and the body, an oil cylinder hole is arranged on a seat of the center frame, a piston is arranged in the oil cylinder hole, oil holes are arranged above and below the piston respectively, two rims of the body are respectively provided with an edge of a certain width, the seat of the center frame is positioned at the edges, the width of a pressing plate is larger than the distance between the two rims of the body, the pressing plate is positioned below the edges of the two rims of the body and fixedly connected with a piston rod of the piston, and the oil cylinder hole is provided with a gland which is positioned above the piston. By respectively filling oil into the two oil holes, the piston drives the pressing plate to vertically move, so that the center frame and the body are locked. The device is simple in structure, easy in realization and fine in locking effect.
Description
Technical field
The utility model relates to a kind of lathe centre frame and lathe bed locking device, and particularly a kind of lathe centre frame and lathe bed hydraulic locking apparatus belong to equipment manufacturing field.
Background technology
When machine tooling, workpiece generally is positioned on the centre frame, and the general split manufacturing of centre frame and lathe bed is carried out in order to make processing smoothly; Must centre frame and lathe bed be fixed together, at present, though be the machine tool or the centre frame of Digit Control Machine Tool fixing with bed piece all be that the employing manual mode is fixed; This mode amount of labour is big, and efficient is low, low precision; Waste time and energy, can also cause the wearing and tearing of parts for a long time, cause processing long non-cutting time.
Summary of the invention
The utility model is for providing a kind of lathe centre frame and lathe bed hydraulic locking apparatus, so that realize the fixing automatically of centre frame and lathe bed.
A kind of lathe centre frame and lathe bed hydraulic locking apparatus that the utility model provided; Comprise centre frame and lathe bed, the centre frame pedestal of centre frame is provided with oil har opening, and piston body is set in the oil har opening; Above and below at piston body is provided with oilhole respectively; The lathe bed two edges are provided with the edge of certain width, and the centre frame pedestal is positioned at along last, platen width greater than the lathe bed two edges along between distance and be positioned under the edge of lathe bed two edges; The piston rod of pressing plate and piston body is fixedly connected; Oil har opening is provided with gland above piston body, pressing plate connects through bolt with the piston body rod of piston body, and what the lathe bed two edges were provided with certain width is the opening rectangular channel along the below.
This device moves up and down the locking that realizes centre frame and lathe bed through making piston body drive pressing plate to two oilhole oilings respectively, and this apparatus structure is simple, is easy to realize that locking effect is good.
Description of drawings
Accompanying drawing 1 is the sketch map of the utility model.
The specific embodiment
In order to explain enforcement of the present invention more fully, the instantiation of the utility model is provided, present embodiment only is to the elaboration of production technology of the present invention and explanation, does not limit the scope of the invention.
Shown in accompanying drawing, hydraulic pressure centre frame 1 is used to support part to be processed, is installed on the centre frame pedestal 2; Centre frame 1 is fixed together with centre frame pedestal 2, and centre frame pedestal 2 is provided with oil har opening, and piston body 4 is set in the oil har opening; Oilhole 9 is set respectively in the above and below of piston body 4 leads in the oil har opening with oilhole 8, lathe bed 1 two edges are provided with the edge of certain width, and centre frame pedestal 2 is positioned at along last; Pressing plate 5 width greater than lathe bed 1 two edges along between distance and be positioned under the edge of lathe bed 1 two edges; Pressing plate 5 is fixedly connected with the piston rod of piston body 4, and oil har opening is provided with gland 3, the effectively stroke of control piston body above piston body 4; Pressing plate 5 is fixedly connected through bolt 7 with the piston body rod of piston body 4; What lathe bed 1 two edges were provided with certain width is the opening rectangular channel along the below, makes pressing plate that the space of upper and lower displacement arranged, and cylinder body prevents hydraulic fluid leak through sealing ring.
The course of work of the utility model is:
When needs are locked; Hydraulic oil promotes piston body 4 through oilhole 8 oil-feeds and moves up, and piston body 4 drives pressing plate 5 and moves together, and 1 locking is one to pressing plate 5 with bed piece with centre frame pedestal 2; When needs unclamp; Hydraulic oil promotes piston body 4 through oilhole 9 oil-feeds and moves down, and piston body 4 drives pressing plate 5 and moves together downwards, and pressing plate 5 is pushed centre frame pedestal 2 and lathe bed 1 open certain distance and realized unclamping.
After the embodiment that specifies the utility model; Being familiar with this technological personage can be well understood to; Do not break away from above-mentioned claim with spirit under can carry out various variations and modification; All foundations technical spirit of the present invention all belongs to the scope of technical scheme of the present invention to any simple modification, equivalent variations and modification that above embodiment did, and the utility model embodiment of also not being subject in the specification to be given an actual example.
