Description

Lathe synchronism mechanism in parallel
Technical field
The present invention relates to a kind of lathe synchronism mechanism in parallel.
Background technology
Existing Numeric Control Technology is the developing direction of current equipment manufacture industry, and in general, in a numerical control device, numerical control electric part accounts for about 1/3rd of lathe cost.In order to the function of maximum performance digital control system, enhance productivity, reduce costs, can once complete two pieces or more than one piece product (parts) processing be the target that those skilled in the art pursue.In order to achieve the goal, often series design is carried out to existing lathe.But because the installing space of lathe is limited, after series connection, there will be unhandy consequence.Such as in numerically controlled lathe, install two main shafts in the side of lathe, its cross slide (X to) and longitudinal planker (Z-direction) are cascaded.The result of such design be below main shaft away from operator, clamping workpiece and cutter extremely inconvenient, cannot really enhance productivity.And fill cutter limited space, two lathe tools can be installed at most, the feature of Digit Control Machine Tool flexibility, high flexibility cannot be played at all, in practical application is promoted, unsatisfactory.
In order to enhance productivity in limited Installing machine tool space and play the feature of Digit Control Machine Tool, those skilled in the art have made long-term effort, but blank wall.So far all do not occurred in commercially available prod enhancing productivity and played the feature of Digit Control Machine Tool, the numerical control device of the installing space of lathe can have been taken into account again completely.Not only make manufacturer production cost remain high always, also make the workman of operating numerical control lathe feel more inconvenience.
Therefore, existing lathe existing defects, be badly in need of providing a kind of really can play digital control system function, enhance productivity and the lathe mechanism reduced costs.
Summary of the invention
The object of this invention is to provide a kind of really can play digital control system function, enhance productivity and the lathe reduced costs synchronism mechanism in parallel.
Basic conception of the present invention is: have employed the problem that is synchronized with the movement that parallel synchronism mechanism to solve in numerical control two main shaft or multiple main axle machine tool, and lathe mechanism comprises lathe headstock and main shaft and divides and be listed in lathe both sides; Saddle and middle carriage are independence; Saddle is connected on longitudinal direction (Z-direction) screw mandrel by nut, and Z-direction screw mandrel is left-right rotary Bidirectional-screw; Middle carriage is connected with line slideway by line slideway block, and line slideway is arranged on synchronous frame in parallel; Frame in parallel synchronous is linked together by horizontal (X to) feed screw nut and horizontal (X to) screw mandrel; Laterally (X to) screw mandrel is arranged on lathe bed.
In the present invention, machine tool dragging plate motion implementation is: saddle is (Z-direction) motion longitudinally, longitudinally (Z-direction) screw mandrel is under the drive of lead screw motor, be rotated, because Z-direction screw mandrel is left-right rotary Bidirectional-screw, lathe saddle does rectilinear motion in opposite directions under the drive of nut.Relative to the main shaft of both sides, lathe longitudinal (Z-direction) achieves and is synchronized with the movement.Middle carriage is (X to) motion laterally, laterally (X to) screw mandrel is under the drive of lead screw motor, be rotated, synchronous frame in parallel does rectilinear motion under the drive of nut, drives two middle carriages to be synchronized with the movement by the line slideway block of two on line slideway.Because line slideway selects precompressed model, forward and reverse motion does not have gap, so just achieves the absolute synchronization that transverse direction (X to) is moved.Solve in prior art to realize the movement interference problem that processing two workpiece produce.Because middle carriage is connected on parallel kinematic frame by line slideway block and line slideway, lathe is when doing lengthwise movement, and line slideway can not limit the lengthwise movement of lathe, and line slideway block slides on line slideway, and motion can not produce interference.
Lathe headstock described in the present invention and main shaft can be multiplied, as 4 groups of lathe headstocks and main shaft, and 6 groups of lathe headstocks and main shaft etc.So, just can give full play to the feature of Digit Control Machine Tool and effectively enhance productivity.
Specifically, lathe of the present invention synchronism mechanism in parallel comprises bed piece, it is characterized in that described bed piece side has the first main spindle box, described bed piece opposite side has the second main spindle box, described first main spindle box has the first main shaft, described second main spindle box has the second main shaft, described first main shaft and the second main shaft are oppositely arranged, bed piece both sides between described first main shaft and the second main shaft have longitudinal rail, described longitudinal rail and the first main shaft and the second main axis parallel, in the middle part of described bed piece, there is longitudinal screw mandrel, described bed piece being provided with longitudinal screw mandrel is the cross lead screw of cross arrangement, in the both sides being positioned at cross lead screw, there is the first assembly and the second assembly respectively, described first assembly and the second modules in parallel are arranged, described first assembly has first planker, first middle carriage, first line slideway block and the first knife rest, described first planker is connected with longitudinal screw mandrel by nut, described first middle carriage side is fixedly connected with the first line slideway block, described first knife rest is towards the first main shaft, described first assembly both sides have the first assembly cross slide way, described second assembly has second largest planker, second middle carriage, second line slideway block and the second knife rest, described second largest planker is connected with longitudinal screw mandrel by nut, described second middle carriage side is fixedly connected with the second line slideway block, described second knife rest is towards the second main shaft, described second assembly both sides have the second assembly cross slide way, described cross lead screw side is connected with synchronous frame in parallel by screw nut driving, the synchronous frame of described parallel connection has line slideway, described first line slideway block is connected with line slideway with the second line slideway block.Described longitudinal screw mandrel can be left-right rotary Bidirectional-screw in the present invention.
Main shaft described is in the present invention distributed in lathe both sides, not easily produces resonance during turning.Independently large upper slide rest, can install the multiple cutter hubs such as electric driving tool post.Main shaft is the same with machine tool to the space length of operator, very convenient.Really achieve a set of digital control system and control two independently process, two workpiece can be processed simultaneously in time processing, greatly improve labor productivity, there are wide market prospects.
Compared with the aforementioned existing similar products, lathe of the present invention synchronism mechanism in parallel can really play digital control system function, enhance productivity and reduce costs.
Content of the present invention is further described with the following Examples, but content of the present invention is not limited only to content involved in embodiment.
