Description
Affiliated technical field
The present invention relates to lathe, robot and coordinate measuring machine field, especially can be used for the circular arc or the circular gantry structure of Digit Control Machine Tool, transfer robot and mechanical measuring machine.
Background technology
Present known lathe, machinery structurally all have following a few class:
1, the gantry structure of present known Digit Control Machine Tool all is having the shape of a real square door shape cascaded structure, and all is to constitute gantry by 3 parts (2 columns, 1 crossbeam), and 3 parts bring many difficulties for production links such as manufacturing, assembling, check; Constitute the lathe that gantry is feature by 3 parts (2 columns, 1 crossbeam), gantry machining center particularly, when doing the circular arc working motion, the interpolation that needs to link more than two just can be finished, and the movement locus of lathe (3 gantry machining centers) is not a circular arc, and it is very big that the precision of processing is influenced by the precision of machine tool structure; Five Longmen machine tools must be equipped with the multi-angle main tapping could realize polyhedron processing, when doing five working motions, when particularly main shaft is machined to the workpiece installed surface, owing to limited by the lathe gantry structure, cause the main shaft cantilever long, processing rigidity straight line descends, and causes machining accuracy and working (machining) efficiency low.
2, present known parallel institution Digit Control Machine Tool, the mechanism that position and the attitude of this control cutter in the space changes, mainly form by pedestal, motion platform, connecting rod, this lathe has been broken the notion of traditional machine tool structure fully, abandon the cutter guidance mode of fixed guide, brought the difficulty of many aspects such as manufacturing, control, operation, program composition; And its working range is limited, the attitude angle of motion platform particularly, and generally about 30 degree, the machinable zone of cutter is very limited; They mostly are made up of the type of attachment of 2DOF and 3DOF turning joint simultaneously, and parts are numerous, and the precision of parts and assembly precision directly influence the machining accuracy of parallel machine.In the working motion of reality, machine tooling (is crossed quadrant) near the workpiece installed surface time, the long connecting rod rigidity deficiency that causes of cantilever, and rigidity and precision that this has not only reduced lathe also are difficult to adapt to the needs of the interlocked numerical controlled working motion of high inclination-angle multi-coordinate.
3, present known grinding machine, it all is the structure that workpiece and bistrique do relative motion in rotation, machining accuracy is subjected to the rotating accuracy of the rotating shaft of holding workpiece, the location precision of bistrique, and workpiece super large or special-shaped machining accuracy more be cannot say for sure to demonstrate,prove, as: the grinding machine of machining large bent axle, because the malaignment of workpiece machined surface, rotary centrifugal force is big, has limited the raising of machining accuracy and efficient.
4, present known gantry frame type coordinate measuring machine, when measuring spherosome, all be to get any or multiple spot at 3 to constitute circular arc line and measure calculating on spheroid, this metering system is not that the circular arc of following spherosome is measured, and the accuracy of measurement and precision are all restricted.
5, the present known transfer robot that is applied in the industrial production has articulated 2 kinds of gantry frame type and single armed.The robot energy carrying heavy goods of gantry frame type, but very single on the direction of carrying, can not realize multi-direction carrying article; The single armed articulated robot can be realized multi-direction carrying, but the weight of carrying article is subjected to the restriction of jib-length, and carrying weight is lighter relatively.
Above-mentioned lathe, machinery structurally all have technical defective, and difficulty is big on control and manufacturing, the mounting technology.
Summary of the invention
In order to overcome existing lathe, mechanical structures technical disadvantages, the invention provides a kind of brand-new circular arc or the machine tool structure at circular gantry, adopt the lathe working space of this structure big, manufacturing, assembling, easy to operate, this structure lathe only needs moving components such as main shaft to follow on circular arc or circular gantry when doing circular motion track just can be done circular motion, and cantilever is short, rigidity and precision height.This structure lathe can also be realized quadrant motion, and angle can surpass 180 degree and cantilever is very short, good rigidly; This structure lathe can overcome control, operation, program composition, the manufacturing of parallel kinematic mechanism machine, the complexity of measurement update; The machine tool structure at circular arc or circular gantry is used in grinding machine, and workpiece is maintained static, powerful centrifugal force shortcoming when not had the workpiece rotation, and bistrique moves in a circle at workpiece relatively, has improved machining accuracy and efficient.
The technical solution adopted for the present invention to solve the technical problems is: tradition is designed, manufactures 1 (it is one that crossbeam and column hold) circular arc or circular portal frame by the having the shape of a real square track portal frame that 3 parts (1 crossbeam, 2 columns) constitute, connect main shaft, knife rest, bistrique or other workpiece by planker, just can realize D translation and three-dimensional motion output; Realize surpassing 180 main body motions degree or circumference.
The present invention uses in lathe, machinery has following beneficial effect:
1, gantry structure is whole circular arc or circle, and lathe can very accurately carry out circular arc or circus movement.
2, gantry structure becomes whole circular arc or circle, increases structural strength, the rigidity at gantry very effectively.
3, gantry structure becomes whole circular arc or 1 circular parts, and self just has the upright supports effect, has simplified gantry structure, makes, assembles and lacked 2 parts than the traditional dragon door, and manufacturing, assembling, work for inspection amount have also lacked 2/3.
4, gantry structure becomes whole circular arc or circle, replace two axial functions of traditional dragon door lathe, when the workpiece of cutting circular arc feature, improved cutting part (particularly main shaft) mechanics direction, and lathe need not just four machining functions of realizing five of energy of multi-angle head; The workpiece special mounting can also realize six processing.
5, gantry structure becomes whole circular arc or circle, can realize that workpiece is motionless, and cutter moves relative to the workpiece swing offset, can process super large, overweight workpiece that traditional machine tool can't be processed in theory, and precision is better, efficient is higher.
In a word, the present invention is the exploitation and practical universal providing the foundation of machineries such as multi-shaft interlocked lathe, robot, coordinate measuring machine.
