Description
Technical field
The utility model relates to a kind of lathe mechanism, is specifically related to a kind of main spindle box mobile lathe structure.
Background technology
Traditional automatic lathe main shaft is mainly used in the clamping and the driving of general revolving parts; Characteristics are simple in structure relatively; But do not have self-feeding and holding function, the automaticity of main shaft is on the low side, but can satisfy the processing of general simple profile part basically.
Along with developing rapidly of various complex surface finding demands in recent years, market competition is more and more serious, so the time and the precision of complex surface finding manufacturing proposed new requirement again, the traditional processing device can not meeting the market requirement.
The utility model content
The utility model does not have self-feeding and holding function to existing lathe, the problem that automaticity is low, and a kind of automatic lathe main axle structure is provided.This structure can overcome the weak point of prior art, and its structure optimization, can enhance productivity, and can reduce production costs more greatly.
In order to achieve the above object, the utility model adopts following technical scheme:
The automatic lathe main axle structure comprises main spindle box, water jacket, rotor, bearing seat, encoder, brake apparatus, loose broach shell, Latin, tailstock, mandrel, shift fork roller, shifting fork bar, loose cutter cylinder, bearing, spring, main shaft chuck and push rod, and said main spindle box is fixed on the supporting plate of lathe; Said mandrel is located in the main spindle box, said water jacket, decides commentaries on classics, bearing seat and bearing and is installed in the inner mechanism that forms support mandrel of main spindle box, and said tailstock is set in the tail end of mandrel; And main spindle box joins, and said brake apparatus is arranged on the tailstock, and cooperates with mandrel; Said main shaft chuck movably is placed in the mandrel front end through spring; Said loose cutter cylinder is placed in the main spindle box outside, and its motion end connects the shift fork roller through shifting fork bar, and said shift fork roller cooperates with loose broach shell; Said loose broach shell is placed on the mandrel; And cooperate with a end of push rod in being placed in mandrel, the other end of said push rod cooperates with spring, and said encoder is placed on the mandrel.
The automatic lathe main axle structure that forms according to such scheme is built-in main shaft, need not external motor and drives, and main axle structure pine automatically presss from both sides workpiece, can locate by any direction, does rigid tapping.
Moreover the structure optimization of the utility model is succinct again, good manufacturability; Especially the clamping and loosening automatically of automatic mode, workpiece significantly reduces processing non-cutting time; And can process various profiles according to different cutters, and be not limited to revolving parts, can milling flat; Punching tapping etc. are the main shafts that desirable complicated finding is processed machine tool.
Description of drawings
Further specify the utility model below in conjunction with the accompanying drawing and the specific embodiment.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
The automatic lathe main axle structure that the utility model provides is built-in main shaft, need not external motor and drive, and main axle structure can loose automatically folder workpiece and any direction location.
Referring to Fig. 1; The automatic lathe main axle structure that the utility model provides mainly comprises main spindle box 1, water jacket 2, rotor 3, bearing seat 4, encoder 5, brake apparatus 6, loose broach shell 7, Latin 10, tailstock 8, mandrel 9, shift fork roller 11, shifting fork bar 12, loose cutter cylinder 13, bearing 14, spring 15, main shaft chuck 16 and push rod 18.
Wherein, main spindle box 1 is fixed on the supporting plate of lathe, and mandrel 9 is located in the main spindle box.
Tailstock 8 is set in the tail end of mandrel 9, and main spindle box 1 joins.
According to the automatic lathe main axle structure that such scheme forms, its concrete running is (referring to Fig. 1) as follows:
When 1, lathe is in the material loading state; Pine cutter cylinder 13 stretches out and drives shifting fork bar 12, moves after shifting fork bar 12 connection shift fork rollers 11 force loose broach shell 7, and loose broach shell 7 opens Latin 10; Latin 10 withstands push rod 18; 15 reaches of push rod 18 promotion springs force main shaft chuck 16 reaches and unclamp, and at this moment main shaft is in open configuration, and the outside feed mechanism of lathe can send workpiece 17 forward according to instruction.
After workpiece 17 is delivered to assigned address; Pine cutter cylinder 13 is regained and is driven shifting fork bars 12, and shifting fork bar 12 connects shift fork rollers 11 forces loose broach shell 7 reaches, and at this moment spring 15 automatically resets to promote to move behind the push rod 18 and makes workpiece 17 be in clamped condition; Automatic charging is accomplished, and lathe can start procedure.
When 2, lathe was in machining state, if program need be made Milling Process some of workpiece 17, at this moment brake apparatus 6 stretched out and withstands mandrel 9 and make it be fixed on assigned address, and the brake force of brake apparatus 6 can overcome the cutting force that adds man-hour.
After accomplishing Milling Process, brake apparatus 6 is regained, and main shaft is in free state, can do general revolution processing.
As shown in Figure 1, when this lathe need be done rigid tapping, encoder 5 can feed back the position signalling of main shaft in real time, and minimum output unit is 0.001 °, can accomplish high-precision screw thread processing.
To top architecture advances, the automatic lathe main axle structure can be the shortest being reduced to all non-cutting times in the process, improved the production efficiency of lathe greatly, can reduce production costs more greatly.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
