Abstract
The utility model discloses an automatic correcting mechanism of a microcomputer thread grinding machine. The automatic correcting mechanism is characterized by comprising a shell, wherein the shell is internally provided with a stepping motor which is connected with a ball screw; the outer side of the ball screw is provided with a nut pair; a nut sleeve is arranged at the outer side of the nut pair and in the shell; the top part of the nut sleeve is provided with a contact which is arranged at the outer side of the shell; and the contact is contacted with a correcting rod which is connected with a nut lever by a working platform nut. The automatic correcting mechanism has the advantages that the microcomputer thread grinding machine is modified, the automatic correcting mechanism is added, the variation of minor-cycle errors, local errors and all-length errors of the processed ball screw is obviously improved, the practical average stroke deviation or the linear deviation caused by temperature rise can be compensated, the investment is less, the effect is fast, and the fund is saved for manufacturers. The automatic correcting mechanism is very popular and is convenient for popularization.
Description
Technical field
The utility model relates to the aligning gear field, relates in particular to a kind of microcomputer screw grinder automatic correcting mechanism.
Background technology
Ball screw assembly, is widely applied to all trades and professions of society, and the quality of its quality directly has influence on the development of relevant industries.Screw grinder adopting traditional structure adds man-hour, and its helical pitch precision mainly is that the driving-chain precision of leaning on the master screw pair of nut system of lathe, gear train etc. to be formed guarantees.Therefore, " high-precision machine-tool " promptly " high-precision screw grinder " be vital.Yet common external thread grinder is owing to be open cycle system; The lathe transmission chain error can not be effectively controlled and compensate; Though on lathe, generally all equipped cylinder scale, the operator can repair the accumulated error that the file cylinder scale is partly eliminated master screw by manual work according to the initial workpiece testing result, improves the actual average deviation of stroke of processed leading screw; But the circular error to leading screw is powerless, and efficient is extremely low.
Though the high performance CNC grinder for external thread of high accuracy is arranged, abroad because of expensive (as approximately needing more than 600 ten thousand yuan from Japan, 1 meter external thread grinder of numerical control of Switzerland's import) can not be popularized use.Therefore, present most of leading screw manufacturer is the grinding machine an of century 60, the seventies in the use also, and these lathes are after using and wearing and tearing for a long time, and the error increase often can not be satisfied the needs of high-precision processing.
Therefore, solve existing this problem in the prior art with regard to being badly in need of a kind of improved technology.
Summary of the invention
The purpose of the utility model provides a kind of microcomputer screw grinder automatic correcting mechanism.
The technical scheme that the utility model adopts is:
Microcomputer screw grinder automatic correcting mechanism comprises housing, and said enclosure interior is provided with stepper motor; Said stepper motor is connected with ball screw, and the said ball screw outside is provided with pair of nut, and said pair of nut outside enclosure interior is provided with nut sleeve; Said nut sleeve top is provided with contact; Said contact is located at hull outside, and said contact contacts with adjustable stem, and said adjustable stem is connected with the nut thick stick through the workbench nut.
The utility model has the advantages that: the microcomputer screw grinder being transformed, increased automatic correcting mechanism, is on the basis of improving the lead screw grinding machine precision; Minor cycle error, the local error of processed leading screw, the variation of total length error are all increased significantly; And can both compensate to the actual average deviation of stroke or by the deviation from linearity that temperature rise causes, small investment, instant effect are for manufacturer has practiced thrift fund; Be favourably welcome, be convenient to promote.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model automatic correcting mechanism.
Fig. 2 is the structural representation of the utility model microcomputer screw grinder.
Wherein: 1, housing, 2, stepper motor, 3, ball-screw, 4, pair of nut, 5, nut sleeve; 6, contact, 7, adjustable stem, 8, the workbench nut, 9, the nut thick stick, 10, main spindle box; 11, justify grating, 12, workbench, 13, long grating, 14, the integrated treatment circuit; 15, industrial control microcomputer, 16, lathe, 17, read head, 18, aligning gear.
The specific embodiment
As illustrated in fig. 1 and 2, the microcomputer screw grinder automatic correcting mechanism of the utility model comprises housing 1; Said housing 1 inside is provided with stepper motor 2, and said stepper motor 2 is connected with ball-screw 3, and said ball-screw 3 outsides are provided with pair of nut 4; Said pair of nut 4 outside housings 1 inside is provided with nut sleeve 5, and said nut sleeve 5 tops are provided with contact 6, and said contact 6 is located at housing 4 outsides; Said contact 6 contacts with adjustable stem 7, and said adjustable stem 7 is connected with nut thick stick 9 through workbench nut 8.
Be installed in accurate general round grating 11 and optical reading head 17 on the main spindle box 10 as ball-screw 3 rotating corner benchmark; When circle grating 11 rotates with ball-screw 3; Gather the signal of representing ball-screw 3 corners by read head 17; Simultaneously, ball-screw 3 rotates and moves through drive workbench 12 such as pair of nut 4, and the long grating 13 on the workbench 12 forms the grating measuring signal of representing displacement with lathe 16 read head 17 relative motions on one's body.Through the displacement of integrated treatment circuit 14 with the ball-screw that is measured 3 corner values and workbench; Sampling number by regulation is sent to industrial control microcomputer 15; After industrial control microcomputer 15 data; Can obtain the measurement result of transmission chain error, by measure, lathe 16 errors " at any time " of control software during ball-screw 3 grindings feed back in the aligning gear 18.Sending instruction by industrial control microcomputer 15 makes stepper motor 2 rotate suitable angle according to the size and Orientation of error; To produce an ancillary relief displacement to workbench 12 through adjustable stem 7; Make lathe 16 errors approach " zero " all the time, thereby reach purpose from dynamic(al) correction.
The microcomputer screw grinder being transformed, increased automatic correcting mechanism 18, is on the basis of improving ball-screw 3 grinding machine precision; Minor cycle error, the local error of processed ball-screw 3, the variation of total length error are all increased significantly; And can both compensate to the actual average deviation of stroke or by the deviation from linearity that temperature rise causes, small investment, instant effect are for manufacturer has practiced thrift fund; Be favourably welcome, be convenient to promote.
