Description
Technical field
The present invention relates to a kind of fixture of cutter production, especially a kind of Multi-station rotary type of disposable type CNC milling cutter
Production fixture.
Background technology
Digit Control Machine Tool is numerically-controlled machine tool（Computer numerical control machine tools）Letter
Claim, referred to as CNC is a kind of automated machine tool equipped with program control system.The control system can be processed logically to be had
Control coding or other symbolic instruction regulated procedures, and decoded, represented with the numeral of code, it is defeated by information carrier
Enter numerical control device.Various control signals are sent by numerical control device through calculation process, the action of lathe, shape by drawing is controlled
Shape and size, automatically process part.Digit Control Machine Tool preferably solves complexity, the zero of precision, small lot, multi items
Part processing problems, are a kind of flexible, dynamical automated machine tools, represent the developing direction of modern machine control technology,
It is a kind of typical electromechanical integrated product.
CNC machining centers all carry tool magazine and automatic tool changer, are transferred not in tool magazine by automatic tool changer
With cutter realize carrying out product the processing of different operations, because face to be processed on product, die cavity and hole are respectively positioned on
On the different side faces of product, in order to ensure that product face to be processed is located at the underface of process tool, it is necessary to machining center pair
The position and angle of cutter and product are adjusted correspondingly, in order to improve the complexity of processing efficiency and different workpieces to be machined
Degree, occurs in that the machining center of three axles, four axles and five axles on the market, and three axis machining center is mainly to cutter in X-axis, Y
The adjustment of position is carried out in the spaces that three directions of axle and Z axis are constituted, being accurately positioned for tool position is realized, but, when treating
Multiple die cavities and EDS maps of converted products are on the side face of product or when hole to be processed is inclined hole, it is necessary to product itself
Angle be adjusted, in this case, it is necessary to the machining center of four axles or five axles, to realize the tune of product self-view
It is whole, but from the cost consideration of machining center itself, the cost of the machining center of three axles, four axles and five axles can double superposition,
The cost of the particularly machining center of five axles is more than four times of three axis machining center, and enterprise is in order to improve the production efficiency of product
Also have to take into account the cost of machining center, in order to evade machining center directly using four axles or five axles, have on the market
Enterprise reaches the purpose of processing by setting product self-view adjustment structure on the workbench at three axis machining center.
A kind of China Patent Publication No. novel processing center of numerical control machine tool for CN102476289A is disclosed, the machining center
It is that some cushion blocks are set in the machine table at three axis machining center, the upper surface of the supporting surface on cushion block and machine table main body is into pre-
Fixed acute angle, the contact surface that supporting surface is contacted selectively as workpiece, the angle of this cushion block supporting surface once presets
Afterwards, cannot just adjust, and the conversion of angle cannot also link up between supporting surface, can only play the adjustment of predetermined angle, it is this
The setting of cushion block serves the effect at Four-axis milling center to a certain extent, but angle outside supporting surface predetermined angle is just
Cannot adjust, there is certain limitation, and when inclined hole or die cavity on product face are distributed on the side face of product, it is this to add
Also uncontrollable product is rotated in a circumferential direction at work center, can only control the adjustment of its machine table angle, it is necessary to dismantle again to be added
Chemical product, after circumferentially adjusting angle and reinstalling, then is processed further, extremely inconvenient, also uncontrollable to be added
The machining accuracy of chemical product, reduces the processing efficiency of product.
