Abstract
The utility model discloses a positioning device for a boring lathe headstock. The positioning device comprises a pressure plate, a bolt, a rotating shaft, an arm and an oil cylinder which are movable and are arranged on the headstock, wherein the pressure plate and the headstock are connected through the bolt and a spherical gasket is arranged between the pressure plate and the bolt; a clamp block is fixed at one end of the pressure plate and a connector is fixed at the other end; the movable arm is hinged inside the headstock through the rotating shaft; the connector is linked with one end of the arm; the oil cylinder provided with a piston is arranged on the headstock, and the piston is linked with the other end of the arm; a disc spring is compressed on the other side of the piston contact arm in the headstock; a clamp signal switch is arranged on the headstock and correspondingly connected with the arm; and a fine-tuning locking cap is arranged on the bolt. The device has the advantages of reliability in positioning, unchanged power loss, simple structure and low cost.
Description
Technical field
The utility model relates to a kind of boring head positioner.
Background technology
The main shaft casing is when the column guide rail moves up and down on tradition floor type boring machine or the milling machine, and the positioner of locking main shaft casing on the column guide rail generally adopts armstrong's patent clamping loosening device, or adopts Hydraulic Elements hydraulic clamp, hydraulic pressure to loosen.Be to improve automaticity, existing adopt hydraulic clamp more, loosen the location, come off duty close electricity or have a power failure after because the motor dead electricity of hydraulic power unit, the operating pressure in the hydraulic jack disappears, clamp mechanism is unclamped the location and is disappeared.When the working energising works on, need reorientate, the main spindle box positioning accuracy is forfeiture just, influences machining accuracy.
The utility model content
The purpose of this utility model is the deficiency that exists at above-mentioned prior art, provides a kind of location reliable, the boring head positioner of dead electricity fixed position.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of boring head positioner comprises pressing plate, bolt, rotating shaft, arm, oil cylinder movable on the main spindle box; Described pressing plate is connected by bolt with main spindle box, is provided with spherical washer between described pressing plate and the bolt; Be set with clamp on described pressing plate one end, the pressing plate other end also is set with connector; Arm by the hinged activity of rotating shaft in main spindle box; One end of described connector and arm connects; Described main spindle box is provided with the oil cylinder of piston, the other end of piston link arm; The opposite side of the piston contact arm in main spindle box presses a cover dish spring is set.
In order to make the staff obtain main spindle box clamped condition on the column guide rail easily, corresponding connection with arm is provided with a clamping signal switch on described main spindle box.
In order to make pressing plate be in more satisfactory state, a fine setting locking cap is set on described bolt.
The beneficial effects of the utility model: pressed by the opposite side of the piston contact arm in main spindle box a cover dish spring is set, when dead electricity, the oil cylinder oil pressure disappears, mechanical type butterfly spring is unaffected, make and move clamp on the arm and be clamped on the column guide rail, and energising is loosened, main spindle box could move.It is constant to clamp back positioning accuracy dead electricity, and it is stable to improve the lathe positioning accuracy.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the structural representation cutaway view of the utility model boring head positioner.
Among the figure: 1. column guide rail, 2. main spindle box, 3. arm, 4. dish spring, 5. clamp, 6. rotating shaft, 7. bolt, 8. pressing plate, 9. connector, 10. clamping signal switch, 11. oil cylinders, 12. hydraulic fluid ports, 13. fine setting locking caps, 14. spherical washer, 15. pistons.
The specific embodiment
In order to make pressing plate be in more satisfactory state, a fine setting locking cap 13 is set on described bolt.Remaining is with embodiment 1.
Operation principle of the present utility model is, boring head positioner according to the above embodiments introduction, in processing, when needing to adjust the main spindle box position, make oil pump work from hydraulic fluid port 12 fuel feeding, oil cylinder pusher arm under the effect of oil pressure is moved downward, thereby the pressure that arm is acted on the connector disappears, clamp clamps and loosens, and can make main spindle box move adjusting position.In the time will locating or when next, dead electricity is not worked oil pump, and the oil pressure in the oil cylinder disappears, and compacted dish spring pusher arm moves up, thereby makes arm clamping platen upper binding head, and clamp is clamped on the column guide rail, and the main spindle box location is motionless.
Claims (3)
1. a boring head positioner comprises pressing plate, bolt, rotating shaft, arm, oil cylinder movable on the main spindle box; Described pressing plate is connected by bolt with main spindle box, is provided with spherical washer between described pressing plate and the bolt; Be set with clamp on described pressing plate one end, the pressing plate other end also is set with connector; Arm by the hinged activity of rotating shaft in main spindle box; One end of described connector and arm connects; Described main spindle box is provided with the oil cylinder of piston, the other end of piston link arm; It is characterized in that: the opposite side of the piston contact arm in main spindle box presses a cover dish spring is set.
