Description
Technical field
The present invention relates to machinery processing apparatus field, relate in particular to a kind of locking device of general horizontal lathe knife rest knife plate.
Background technology
At present, existing lathe generally adopts traditional frame knife rest, two cover knife plates is installed and is carried out turning.When turning tool setting, the locking state of knife rest knife plate must be totally released, otherwise can be subject to restriction and the interference of knife rest latch segment.Traditional knife rest latch segment has only designed holding screw, before knife plate moves, while unclamping holding screw, knife rest latch segment can not unclamp knife plate in time, easily knife plate moving process is produced and interfered, more greatly and for a long time more easily there is not this interference during mobile knife plate to pressing plate coupling mechanism force in knife rest latch segment particularly, so just for workman's operation, brings a lot of unnecessary difficulties, affected the efficiency of production and processing.
Summary of the invention
Based on this, be necessary to provide a kind of locking device of general horizontal lathe knife rest knife plate.
Its technical scheme is, the locking device of general horizontal lathe knife rest knife plate, described frame knife rest knife plate locking device, mainly comprise knife rest, on described knife rest, be provided with pressing plate mounting groove, in described mounting groove, be provided with screwed hole, top board and lower platen are installed in the described pressing plate mounting groove on described knife rest by described screw, and described knife plate is installed between described top board and described lower platen.Described pressing plate is provided with groove, knife rest latch segment is installed in groove by holding screw, described in being provided with, described knife rest latch segment unclamps screw, only on latch segment, do screwed hole, not heavy screwed hole on tool-post structure, after unclamping holding screw, by unclamping screw described in rotating, described knife rest latch segment is ejected.
Therein in an embodiment, between described knife rest latch segment and pressing plate contact-making surface, be provided with spring assembly, during locking holding screw, described spring is in compressed state, before mobile knife plate, while unclamping described holding screw, compressed described spring applies an outside thrust can to described knife rest latch segment, latch segment is ejected, described latch segment and described knife plate are departed from completely, improve the flexibility that described knife plate moves.
In an embodiment, described knife plate one end is provided with nut seat, on described nut seat, screw mandrel is installed therein, and power is inputted on described screw mandrel, realizes the feeding of described knife plate by rotating described screw mandrel.
In an embodiment, described knife plate, before completing feeding, need to unclamp holding screw, unclamps knife rest latch segment therein, and rotary screw moves knife plate; After feeding completes, during described knife rest work, described locking holding screw, described immovable support latch segment, utilizes the contact inclined-plane between described knife rest latch segment and described knife plate that power is decomposed to vertical direction, with this, realizes the locking of described knife plate.
Above-mentioned knife rest knife plate locking device, production and processing is convenient, is convenient to install; Locking process is simple, safe, easy to control.Utilize the contact inclined-plane between knife rest latch segment and knife plate that power is decomposed to vertical direction, with this, realize the locking of knife plate.Under the prerequisite that does not drop into higher cost, improve the flexibility that latch segment moves, enhance productivity.
Accompanying drawing explanation
Fig. 1 is axle side schematic diagram of the present invention;
Fig. 2 is that Fig. 1 intermediate slide latch segment of the present invention changes cross-reference figure;
Fig. 3 is that Fig. 1 center platen of the present invention changes cross-reference figure.
The specific embodiment
Below in conjunction with accompanying drawing, the present embodiment is described further.
Refer to Fig. 1 Fig. 2 and Fig. 3, the frame knife rest knife plate locking device of a kind of general horizontal lathe providing for the preferred embodiment for the present invention, for realizing the locking of knife plate.Concrete, described locking device comprises knife rest 5, and knife rest 5 is provided with pressing plate mounting groove 12, is provided with screwed hole 13 in mounting groove 12, top board 3 and lower platen 3 are installed in the pressing plate mounting groove 12 on knife rest 5 by screw 2, and knife plate 6 is installed between top board 3 and lower platen 3.
Described pressing plate 6 is provided with groove 8, knife rest latch segment 4 is installed in groove 8 by holding screw 1, knife rest latch segment 4 is provided with and unclamps screw 9, only on knife rest latch segment 4, do screwed hole 13, not heavy screwed hole 13 on knife rest 5 bodies, after unclamping holding screw 1, by rotation, unclamp screw 9 knife rest latch segment 4 is ejected.
Between described knife rest latch segment 4 and pressing plate 3 contact-making surfaces, be provided with spring assembly 10, during locking holding screw 1, spring 10 is in compressed state, before mobile knife plate 6, while unclamping holding screw 1, compressed spring 10 can apply an outside thrust to knife rest latch segment 4, and knife rest latch segment 4 is ejected, knife rest latch segment 4 and knife plate 6 are departed from completely, improve the flexibility that knife plate 6 moves.
Described knife plate 6 one end are provided with nut seat 11, and screw mandrel 7 is installed on nut seat 11, and power is inputted on screw mandrel 7, realizes the feeding of knife plate 6 by rotary screw 7.
