Description
Technical field
The utility model relates to a kind of tool arm locking device of lathe.
Background technology
Existing lathe is all using machine knife as main cutting tool, under the requirement and trend of machine tool high speedization running, machine spindle speed constantly promotes, need tool arm to keep static when carrying out tool changing, therefore need to lock tool arm, firm with installation with registration when keeping tool changing.Tool arm lock cutter mechanism complex structure of the prior art, fault rate is higher.
Utility model content
In order to solve the above problem existed in background technology, the utility model provides a kind of tool arm lock knife system of lathe, and it is simple that this lock knife system has structure, high reliability.
For achieving the above object, the utility model adopts following technical scheme:
A tool arm lock cutter mechanism for lathe, comprise tool arm and lock knife system, tool arm is arranged on centre rotational axis, and the two ends of tool arm are provided with machine knife by machine knife seat, it is characterized in that:
Described lock knife system comprises cam, transmission arm and clamping block, the axle bed of centre rotational axis is fixed with projecting block, the side of projecting block is by the hinged transmission arm of jointed shaft, described transmission arm is L-type, its one end and the cam engagement be arranged on axle bed, the hinged clamping block of the other end, cam has breach, transmission arm swing is driven after cam rotates, thus drive clamping block to move back and forth at the upper surface of projecting block, clamping block is provided with lock hole towards the side of tool arm, position corresponding with lock hole on tool arm is provided with locking projections, after locking projections enters lock hole, tool arm is locked.
Spring is provided with between described transmission arm and projecting block.
The position of transmission arm and cam contact is provided with roller bearing.
The beneficial effects of the utility model are: structure is simple, and reliability is high, not easily breaks down.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Fig. 1 is the structural representation of lathe tool arm described in the utility model lock cutter mechanism;
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be further described:
Embodiment 1
As shown in Figure 1, a kind of tool arm lock cutter mechanism of lathe, comprise tool arm 2 and lock knife system, tool arm 2 is arranged on centre rotational axis 1, the two ends of tool arm 2 are provided with machine knife 3 by machine knife seat, described lock knife system comprises cam 5, transmission arm 6 and clamping block 4, the axle bed of centre rotational axis is fixed with projecting block 8, the side of projecting block 8 is by the hinged transmission arm 6 of jointed shaft 62, described transmission arm 6 is L-type, described transmission arm 6 one end engages with the cam 5 be arranged on rotating shaft base, the hinged clamping block 4 of the other end, cam 5 has breach 51, cam 5 can make transmission arm swing after rotating, thus drive clamping block 4 to move back and forth at the upper surface of projecting block 8, clamping block 4 is provided with lock hole towards the side of tool arm, position corresponding with lock hole on tool arm 2 is provided with locking projections 21, after locking projections 21 enters lock hole, tool arm is locked.
Be provided with spring 7 between transmission arm 6 and projecting block 8, spring 7 one end is fixed on projecting block 8, and the other end is fixed on one end that transmission arm is connected with clamping block.
