Description
Technical field
The invention belongs to machinery manufacturing technology field, particularly a kind of series-parallel machine tool structural design that has comprehensive function, drives based on slide block.
Background technology
In mechanical manufacturing field, traditional frame for movement is stock-removing machine for example, all has fixing guide rail, and their basic exercise mode is to make cutter or workpiece along fixing guide rail movement.The total this motor pattern of legacy equipment has brought many intrinsic defectives, the supporting member and the high-precision guide track systems that are fixed in supporting member such as clumsy heavy lathe bed, column that must have high rigidity as traditional machine tool cause that lathe weight is big, price is high, move and move difficulty.In addition, the in-line mechanical mechanism design of traditional machine tool makes spatial movement need lean on the mutual superposition of each direction motion to realize, easily produces the accumulation of error, has reduced the terminal precision.
Over past ten years, a kind of new concept lathe has appearred in the world---parallel machine (Parallel Machine Tool).Parallel machine is the hot subject that numerical control research field is in the world paid special attention to, and Chinese scholars is made number of research projects.Parallel machine is knowledge-intensive, intellect-intensive, technology-intensive electromechanical integration high-tech product, is the intersection of multidisciplinary application technologies such as parallel robot, numerical controlled machinery, computer control, accurate measurement, digital control processing.Parallel machine adopts parallel-connection structure, can realize multiple functions such as the interlocked numerical controlled processing of multi-coordinate, assembling and measurement, has degree of modularity height, heavy moving parts is light, precision is high, and response is fast, advantages such as low cost of manufacture.Compare with traditional machine tool, parallel machine has been because of having adopted the form of tool motion, thereby improved performances such as its speed, acceleration, precision and rigidity.
Yet, compare with traditional machine tool, than little, and the orientation capability realized of machine tooling cutter is also less relatively based on the parallel machine working space of pure parallel-connection structure and lathe cumulative volume.Therefore, the orientation capability realized that how to guarantee parallel machine working space and cutter becomes the development parallel machine at first needs the problem that solves.In addition, if can guarantee the high speed characteristics of lathe, realize that to parallel machine is final high process velocity also has important function from configuration.
Summary of the invention
The objective of the invention is in order to overcome the weak point of prior art, use for reference the advantage of parallel machine and traditional machine tool, a kind of series-parallel machine tool based on series parallel structure is proposed, make it both have multiple functions such as cutting, grinding, transfer, assembling, have simple structure, good processing technology, bigger working space, feed speed faster again, preferential advantages such as machine direction.
A kind of high speed three-axis series-multiple connection machine tool structure of the present invention's design comprises 1 horizontal guide rail, and 2 slide blocks that are installed on this guide rail drive 2 linear drives unit that this slide block moves in guide rail, 2 connecting-rods with constant lenghs, 1 mainshaft mechanism that is installed on the connecting-rods with constant lengh.One end of said 2 connecting-rods with constant lenghs is linked together by hinge, and the other end is connected with a said slide block respectively, forms closed linkage in parallel.Said mainshaft mechanism can carry out stretching motion, but closed linkage in parallel with this is independent mutually on driving, and mechanism finally can realize the translational motion of three directions.
One of feature of the present invention is: two connecting-rods with constant lenghs and guide rail form triangle, and according to leg-of-mutton stability principle, this closed linkage in parallel has very high rigidity.Because mainshaft mechanism is installed on one of them connecting-rods with constant lengh, thereby has made full use of the high stiffness characteristics that this closed linkage in parallel had.
Two of feature is: the mounting means of mechanism's slide block has guaranteed that glide direction is the privileged direction of processing, is particularly suitable for processing some special workpieces, as microscler complex part.
Three of feature is: two connecting-rods with constant lenghs are driven by the slide block that is attached thereto, and are also referred to as outer secondary the driving.The prolonging direction of connecting-rods with constant lengh carries out the heat affecting calibration easily as can be known.
Four of feature is: the main motion mechanism of this mechanism is a plane mechanism.Since simple in structure, can carry out deep theory analysis to mechanism, obtain optimum design parameter, also the real-time control for mechanism provides condition.
Content of the present invention is mainly reflected in the plane-parallel type closed linkage, is installed in the mainshaft mechanism on one of them connecting-rods with constant lengh.
Description of drawings
Fig. 1 is a general structure schematic diagram of the present invention.
Fig. 2 is the mainshaft mechanism schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, introduce the structure and the operation principle of a kind of high-speed horizontal three-axis series-multiple connection lathe of the present invention in detail.
As shown in Figure 1, present embodiment is by connecting-rods with constant lengh 4,6, mainshaft mechanism 5, and slide block 3,7, guide rail 1 constitutes the plane-parallel type closed linkage.Owing to adopt frame structure, the very light in weight of total.
Connecting-rods with constant lengh 4,6, the slide block 3,7 that is hinged with it adds the triangle translation structure that upper rail 1 is formed, according to triangle intrinsic stability, structure has good rigidity as can be known.When slide block 3,7 changed positions, the pin joint of bar 4,6 was also along with corresponding change, the also corresponding change in position of bar 4,6 simultaneously with posture, and then drive mainshaft mechanism 5 positions that are fixed on the bar 6 and the variation of posture.
Linear drives unit 2,8 drives slide block 3,7 respectively and slides on horizontal guide rail 1.The slide block glide direction is the advantage direction of motion of lathe as can be known, and this direction and the sufficient decoupling zero of other direction of motion are particularly suitable for the processing of elongated workpiece.Owing to be that slide block drives, can carry out thermal calibration easily on the length direction to connecting-rods with constant lengh 4,6.
Mainshaft mechanism 5 is fixed on the bar 6, has made full use of the high stability and the high stiffness characteristics of triangle translation structure.
As shown in Figure 2, the mainshaft mechanism 5 with locomotive function is made up of spindle motor 10 and main shaft casing 9, and wherein main shaft casing 9 comprises the parts of drive shaft stretching motion.The direction of motion of spindle motor is consistent with the normal direction on plane, closed linkage in parallel place, has effectively enlarged the range of work of lathe.In addition, the motion of spindle motor is separate with closed linkage in parallel on driving.
Connecting-rods with constant lengh 4,6 is 950mm in the present embodiment, and effective sliding stroke of guide rail 1 is 2350mm, and reached at the territory of spindle motor central point is that (X * Y * Z), wherein the Z direction is the flexible direction of spindle motor to 500*500*300mm.
