Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, embodiment of the present utility model provides a kind of external screw thread grinding-milling equipment, comprise a lifting platform 1 and can make the workbench 2 of feed motion by relative described lifting platform 1 with one, described lifting platform 1 relatively workbench 2 side is provided with one for the emery wheel 4 of grinding work piece 3, described workbench 2 is provided with a support 5, and described support 5 is provided with one for fixation workpiece 3 and the hold assembly 6 that workpiece 3 can be driven to rotate.
Concrete, by regulating lifting platform 1, the grinding feed point of emery wheel 4 opposite piece 3 is fixed, emery wheel 4 is driven to rotate, workbench 2 drives the relative emery wheel 4 of workpiece 3 to carry out length feed, hold assembly 6 drives workpiece 3 to rotate by certain angle simultaneously, emery wheel 4 grinding on workpiece 3 is made to form external screw thread, the present embodiment adopts emery wheel 4 grinding, the frictional force that workpiece 3 is subject to and radial force all less, improve the externally threaded machining accuracy of workpiece 3, simultaneously by adopting ultra-thin emery wheel 4 machining screw tooth apart from less workpiece 3, producing meticulousr screw thread.
Essentially, the present embodiment further improves on the basis of turnery processing and Milling Process, achieves and improve the processing of externally threaded high-fineness, improve the compactness of screw thread.
Emery wheel 4 can produce iron filings when grinding work piece 3, because emery wheel 4 is high-speed rotation, easy drive iron filings fly away from more remote, make iron filings in machining area more, although major part is siphoned away by dust catcher, but have the part of not easy to clean, therefore described workbench 2 is magnetic worktable, this magnetic worktable has magnetic, the iron filings produced when magnetic-adsorption workpiece is ground can be produced, the preferred electromagnetically workbench of magnetic worktable of the present embodiment, magnetic force is provided for magnetic worktable by the open close of power supply, when needs cleaning iron filings, can by power-off, thus be more convenient to cleaning.
Further, described external screw thread grinding-milling equipment also comprises first control device 7 and second control device 8, described first control device 7 makes upper and lower vertical motion for controlling described lifting platform 1, and described second control device 8 does feed motion for controlling relative emery wheel 4 axis parallel of workbench 2.First control device 7 in the present embodiment and second control device 8 are by being connected with a digital control system, digital control system controls the speed of the height that moves up and down of lifting platform 1 and workbench 2 feed motion by program code, control lifting platform 1 to move up and down and move up and down to determine feed point for controlling emery wheel 4, and then determine the grinding depth of screw thread, and the displacement controlling workbench 2 feed motion generation is mainly used in determining that the anglec of rotation of workpiece 3 is to determine the pitch of screw thread.Simultaneously, the external screw thread grinding-milling equipment of this enforcement also comprises one for controlling the 3rd control device 9 of hold assembly 6 turned position, 3rd control assembly 9 is by being connected with digital control system, its rotating speed is controlled by program code, namely feeding and the rotation of workpiece 3 is controlled by processor, make the feed motion of workpiece 3 and rotation carry out interpolation, make emery wheel 4 grinding on workpiece 3 form required screw thread.Concrete, the external screw thread grinding-milling equipment of the present embodiment can adopt identical digital control system to control with the turning process of prior art, this digital control system can adopt the program code of prior art to control feeding and the rotation of workpiece, but the feed-speed of the present embodiment is different with the obvious and existing turning process of rotary speed, need amendment feed speed and spin speed profile, in specific operation process, need the parameter revising digital control system during the workpiece grinding external screw thread of various outer diameter, the amendment of this place comprises the amendment of feed speed and rotary speed.In addition, the program code of the present embodiment also can be developed again, does not describe in detail at this.
It is interpolation that second control device 8 and the 3rd control device 9 add man-hour, and its interpolation is closed and is: the system perspective of (second control device 8 running lengths/ridge distance) * the three control device 9.General digital control system programming maximum quantity is: 99999999, and the precision of the digital control system programming of this device is after decimal point 4, digital programmable maximum be 9999.9999. then the 3rd control device 9 single maximum number of turns of programming be 9999.9999/360 degree=27.7777(unit: circle); Suppose that ridge is apart from being 0.25, (0.25mm/ circle) * 27.7777 encloses=6.9444mm, then single programming is the longest is 6.9444mm.Therefore, under these conditions, be 36 degree by the whole circle angle configurations of the 3rd control device 9 in this device, the processing length of most of minor thread can be met.
For the ease of emery wheel 4 and workbench 2 the depth of parallelism and, described external screw thread grinding-milling equipment also comprises a trimming device 10, described trimming device 10 is for controlling emery wheel 4 parallel motion relatively in the horizontal plane of described workbench 2, its objective is the relative parallel positions between trimming wheel 4 and workbench 2, and then determine the perpendicularity of workpiece 3 and emery wheel 4.Generally, repaired the upright position up and down of workpiece 3 and emery wheel 4 by trimming device 10, make workpiece 3 axis and emery wheel 4 axis be in same perpendicular, now feed point is the peak of workpiece 3.Also repair by trimming device 10, make emery wheel 4 from workpiece 3 side feed, this feed mode can make the iron filings of generation vertically fall on the table, thus is convenient to cleaning, and reduces the possibility of hurting sb.'s feelings, and improves security.Trimming device 10 shell of the present embodiment manually operates, also can be connected with digital control system and be repaired by digital control system, if be directly connected with digital control system, then workbench 2 can realize the motion of all around four direction in horizontal plane, and it can be realized by prior art.
