Abstract
The utility model discloses an axial fine adjustment mechanism of an engraving machine main shaft. On the basis of the main shaft (4), a main shaft base (10) and main shaft clamping mechanisms (11), a threaded rod (1), a nut (2), a thrust bearing (7), a thrust support (5) and a knob (6) are added. The threaded rod (1) or the nut (2) is fixedly connected with the main shaft base (10), the other one of the threaded rod (1) and the nut (2) makes contact with the thrust support (5) through the thrust bearing (7), the thrust support (5) is fixedly connected with the main shaft (4), and the knob (6) is fixedly connected with the rotatable one of the threaded rod (1) and the nut (2) in a rotating mode. The axial direction fine adjustment mechanism has the advantages that the axial height of the main shaft is accurately adjusted, operation is convenient, after the main shaft clamping mechanisms (11) are loosened, the weight of the main shaft can be borne by the self-locking threaded rod (1) and the nut (2), the rotating knob (6) can achieve lifting of the main shaft in a fine adjustment mode, and after the height of a knife point reaches an accurate height, the clamping mechanisms (11) can be tightened, so that the one-off axial adjustment of the height of the main shaft is finished.
Description
Technical field:
The present invention relates to a kind of engraving machine, especially with a plurality of main shafts, can process many spindle engravings machine of a plurality of workpiece simultaneously, belong to technical field of engraving.
Background technology:
Need the cutter of often changing wearing and tearing or fractureing between the engraving machine work in-process, before and after changing, the height of point of a knife must be accurately consistent, to guarantee the continuity of the curved surface of being carved.When the knife-clamping device of existing electric main shaft presss from both sides cutter, the point of a knife extension elongation can change in the clamped front and back of cutter, guarantee the point of a knife high consistency, and single spindle engraving machine can adopt adjusts the Z axis height, and revises Building Z calibration method solution.But for many spindle engravings machine, adjusting the unique way of certain main shaft point of a knife to correct height, is the clamp mechanism of unclamping this spindle drum, with hand rest, lives main shaft and makes it move axially to correct position, then clamping spindle.
Because main shaft weighs 10 kilograms, live main shaft and accurately move to require position and clamp not only require great effort but also be difficult to realize accurate location with hand rest, this has affected the precision of knife up adjustment and the quality of engraving from another side.
Summary of the invention:
The object of the present invention is to provide a kind of new axial micro-adjusting mechanism of engraving machine main shaft, to solve prior art, operate bothersome effort, knife up is adjusted the not high disadvantage of precision.
To achieve the object of the present invention, the present invention is by the following technical solutions:
1, the axial micro-adjusting mechanism of a kind of engraving machine main shaft comprises main shaft (4), spindle drum (10), main shaft clamping mechanism (11), it is characterized in that: increased screw rod (1), nut (2), thrust bearing (7), thrust bearing (5), knob (6), screw rod (1), in nut (2) one is affixed with spindle drum (10), screw rod (1), another in nut (2) contacts with thrust bearing (5) by thrust bearing (7), thrust bearing (5) is affixed with main shaft (4), knob (6) and screw mandrel (1), or in nut (2) rotating one affixed.
2, described thrust bearing (7) can be a rolling bearing, or a sliding bearing, and the latter is by with thrust bearing (5), with the part on screw rod (1) or nut (2), directly contacting and form.
The present invention has the following advantages:
The adjustment of main shaft axial height is accurate, easy to operate, after unclamping main shaft clamping mechanism (11), the weight of main shaft born by screw rod (1) and the nut (2) of energy self-locking, rotation turn-knob (6) can be realized main shaft fine setting lifting, up to after accurate height, can tighten clamp mechanism (11) to point of a knife, complete the adjustment of a main shaft axial height.
The accompanying drawing explanation:
Fig. 1 is the axial micro-adjusting mechanism schematic diagram of the first engraving machine main shaft;
Fig. 2 is the axial micro-adjusting mechanism schematic diagram of the second engraving machine main shaft;
Drawing reference numeral: 1 screw rod, 2 nuts, 4 main shafts, 5 thrust bearings, 6 knobs, 7 thrust bearings, 10 spindle drums, 11 main shaft clamping mechanisms.
