Abstract
The invention relates to equipment for processing bit, in particular to a five-axis linkage numerical control bit grinding machine, which comprises a spindle driven by a machine tool drive system fordriving a workpiece to make rotation and axial feed, and a grinding wheel feeding device for driving a grinding wheel to feed along the radial direction of the workpiece. The equipment is characterized in that the equipment also includes a cross dilatory mechanism located close to the edge of the grinding wheel; the cross dilatory mechanism consists of a radial dilatory plate and an axial dilatoryplate perpendicular to each other; the radial dilatory plate is driven by a drive shaft to move radially along the grinding wheel; the axial dilatory plate is driven by another drive shaft to move axially along the grinding wheel; and a diamond pen is arranged on the cross dilatory mechanism for trimming the grinding wheel. The equipment can drive a workpiece to rotate, radially move, feed grinding wheel and trim profile of the grinding wheel to achieve synchronous linkage, thus improving the grinding accuracy of bit.
Description
Technical field
The present invention relates to a kind of equipment that is used for drill bit processing, specifically is a kind of five axis linkage numerical control drill grinding machine.
Background technology
The existing drill grinder that is used for the drill groove grinding, its structure is generally three-shaft linkage, can control workpiece rotation in the course of work, workpiece moves axially and these three associated action of abrasive grinding wheel feed motion.The drill grinder of this structure, owing to can't be in real time the shape of cutting of abrasive grinding wheel be controlled, therefore the scale error of the drill groove that processes can increase along with the wearing and tearing of abrasive grinding wheel, thereby has reduced the machining accuracy of product.Fiber crops need its section shape is repaired after cutting abrasion of grinding wheel in addition, existing method for trimming generally is on special trimming device, the swing of two golden pens by being positioned at emery wheel outer rim both sides and the outer rim of emery wheel is cut shape repair out two sections approximate circular arcs, this method for trimming is only applicable to the finishing after emery wheel uses, can't be in the emery wheel course of work, its section shape being controlled in real time, its section shape shape is also more single in addition, can't require to change grinding wheel section shape according to the special shape of drill groove.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of and can make that workpiece rotation, workpiece move axially, the finishing of emery wheel feed motion and grinding wheel section shape realizes real-time synchronous interaction, can improve the five axis linkage numerical control drill grinding machine of drill bit grinding accuracy.
Five axis linkage numerical control drill grinding machine of the present invention includes the workpiece that can drive that is driven by the lathe dynamical system and is rotated main shaft with axial feed, also include and to drive the emery wheel feed arrangement of abrasive grinding wheel along the workpiece radial feed, it is characterized in that, it also includes one and is positioned near the cross saddle mechanism of abrasive grinding wheel outer rim, this cross saddle mechanism is made up of orthogonal radially planker and axial planker, described radially planker also can be moved radially along abrasive grinding wheel by a drive shaft, described axial planker is driven and can be moved axially along abrasive grinding wheel by another line shaft, and a golden pen that is used for repairing abrasive grinding wheel is installed in the cross saddle mechanism.
The present invention is owing to increased the crushing part that can link simultaneously on the drill grinder basis of traditional three-shaft linkage, make the finishing of emery wheel in grinding process, to carry out in real time, so just can control grinding wheel section shape in real time, thereby guarantee grinding accuracy; In addition, adopting cross saddle to drive golden pen repairs emery wheel, both be convenient to control, also can have realized any adjustment of grinding wheel section shape, thereby can satisfy the requirement that groove shape changes in the drill bit processing by the variation of golden pen track by digital control system.
Description of drawings
Fig. 1 is a structure principle chart of the present invention;
Fig. 2 is the structure principle chart of overlooking direction of Fig. 1;
The specific embodiment
As shown in the figure, five axis linkage numerical control drill grinding machine includes the workpiece 5 that can drive that is driven by the lathe dynamical system and is rotated main shaft 1 with axial feed, also include and to drive the emery wheel feed arrangement 3 of abrasive grinding wheel 2 along the workpiece radial feed, near the abrasive grinding wheel outer rim, also be provided with a cross saddle mechanism 4, radially planker 41 and an axial planker 42 are formed by one in this cross saddle mechanism, radially planker also can be moved radially along abrasive grinding wheel by a drive shaft, axially planker also can be moved axially along abrasive grinding wheel by another drive shaft, and a golden pen 43 that is used for repairing abrasive grinding wheel is installed in the cross saddle mechanism.
Grinding machine of the present invention is when work, can determine grinding wheel shape by programming, also can be moving or directly or indirectly control cross saddle by control of cnc system or cad/cam with emulation system, golden pen is moved along specific track, make abrasive grinding wheel when carrying out grinding, can keep cutting the shape shape accurately, thereby guaranteed grinding accuracy.
