Description

The vertical double-shaft turning center

Technical field

The utility model relates to the turning equipment that automation is produced in enormous quantities, particularly is adapted to coil the vertical spindle turning equipment of hub class part processing.

Background technology

The numerically controlled lathe and the turning center of domestic production at present have horizontal and vertical two kinds.

Two main shafts that single main shaft that the generally employing level of structure of horizontal lathe is installed or level are installed relatively, one or two knife rest is done two coordinate feed motions separately in horizontal plane or inclined plane, lathe simultaneously can only processing work one end during single main shaft configuration, but lathe while processing work two ends when two main shafts dispose, machine tool structure has determined it to realize the quite loaded down with trivial details difficulty of reliable automatic loading/unloading, so generally all take artificial loading and unloading, but to producing in enormous quantities by the thin axial workpiece of spindle hole, exist a kind of main shaft rear portion to feed the automatic lathe of material automatically, also adopt special-purpose automatic loading/unloading mechanical device sometimes using the cnc lathe in the batch machining of automobile and other industries.

The general employing of the structure of vertical lathe vertically just put one or more main shaft of upwards installing, and one or more knife rests are done two coordinate feed motions separately, also have small amount of vertical to be inverted single spindle Lathe of installing downwards, and main shaft is done two coordinate feed motions.Both can both realize that the part attitude that remains unchanged passes through from lathe, the former is suitable for big-and-middle-sized part processing and helps the stable location of laying of workpiece, can use comparatively simple mechanism realization automatic loading/unloading, the latter is suitable for medium-sized part processing, can utilize chuck pick-and-place workpiece, utilize the axis feeding coordinate motion to transfer workpiece, thereby than the former more convenient realization automatic loading/unloading and automation group line.The single collocation form decision of the main shaft of existing homemade vertical lathe lathe simultaneously can only processing work one end, and device for automatically turning over work pieces is set between lathe during automation group line.

For horizontal lathe, the gravity effect may cause the workpiece end face location to be thrown off during processing medium wt part, is positioned with unstable trend; The part attitude that can not remain unchanged is simply passed through from lathe, thus be difficult to realize automatic loading/unloading, even realize that its structure is also very complicated.

For vertical lathe, the single collocation form of main shaft decision lathe simultaneously can only processing work one end, between lathe device for automatically turning over work pieces need be set during automation group line, and two ends process fully needs many lathes, takes up an area of greatly, and the both subsidiary streams facility is many; Also have the problem that chip removal is smooth, influence crudy when just putting spindle Lathe processing bowl-type work piece inner surface, its realization automatic loading/unloading mode also relative complex.

Summary of the invention

For realizing the desired automatic loading/unloading mode of more efficient more simple and reliable adaptation automated production in enormous quantities, realize compacter production line scheme requirement, the utility model proposes a kind of vertical double-shaft turning center that adopts the two turret configurations of two main shafts.

For this reason, the utility model has adopted following technical scheme:

The vertical double-shaft turning center adopts a kind of new component layouts structure, the two turrets of the two main shafts of configuration, two main shafts are vertical, dislocation, positioned opposite, the vertical inversion of mobile main shaft, tool X1, Z1 two coordinate feed motions, can finish automatic material grasping, the processing of workpiece lower end is finished in cooperation fixedly turret; Fixed main shaft is vertical just to be put, cooperate mobile turret to finish the processing of workpiece upper end, follow rest tool X2, Z2 two coordinate feed motions, the blanking gripper is installed on follow rest and installs on the table top, cooperate X2, Z2 coordinate motion to finish automatic blanking, workpiece enters from the motor-driven raceway of lathe left end material loading, and the motor-driven raceway of right-hand member blanking flows out.

In the technique scheme, owing to adopted heavier spindle unit to do feed motion, therefore it is very necessary to the lifter motion dynamic property to alleviate its weight, so take following measure: the interior dress of the high pulling torque servomotor main shaft that adopts Forced water cooling, power density increases greatly, adopts aluminium alloy main shaft casing to be beneficial to heat radiation and loss of weight; Adopt the welding structural element of appropriate design, guarantee effective loss of weight under the rigidity condition.

In the technique scheme, can adopt the 4-coordinate feeding slide unit system of adaline bed structure characteristics, be specially: X1, the shared slide unit body of X2 axle, shared one secondary guiding rail, but different interval and partially overlap, the position of two main shafts handing-over workpiece must overlap the district at X1, X2 axle; Adopt the roller guide guidance system, satisfy and all can reach fine feeding requirement under the motion high, low speed; Use the grating chi as slide unit position measurement feedback element, set up the lathe closed-loop control system; Use the servo drive system of process, guarantee lathe speed and feed accuracy requirement the use ball-screw of speed, acceleration, sound rigidity optimal design and checking computations.

The beneficial effects of the utility model are described below:

Workpiece can keep an attitude to pass in and out from about lathe respectively, realizes than other more simple and reliable, loading and unloading mode efficiently, the convenient simultaneously automatic production line of setting up; Be inverted main shaft processing inner surface chip removal smoothness, favourable assurance crudy; Unit can realize that the workpiece two ends process fully, and it is little to make that production line takes up an area of, and reduces auxiliary equipment, compact in design.
