Abstract
The utility model discloses a kind of device that can improve lathe feed precision, relate to lathe field, comprise small slide plate, rotating disk, between described small slide plate and rotating disk, be provided with displacement measuring device, described displacement measuring device comprises and is fixed on the main scale in sabot and is fixed on the vernier on small slide plate, and the use of displacement measuring device, makes the control accuracy of small slide plate become 0.02mm from 0.05mm, and when small slide plate makes lathe tool length feed, the depth of cut is reflected on displacement measuring device immediately.
Description
Technical field
The utility model relates to lathe field, is specifically related to a kind of device that can improve lathe feed precision.
Background technology
Small slide plate dial is to control Workpiece length.The scale value direct representation lathe tool of small slide plate dial is along the axially movable distance of workpiece, i.e. the excision amount of length direction.Small slide plate dial is used for controlling lathe tool and vertically moves distance, and the dial of small slide plate is arranged on small slide plate screw mandrel.When small slide plate handle rotates one week, drive dial, small slide plate screw mandrel also to rotate one week.At this moment be fixed on the nut coordinating with screw mandrel on small slide plate and move certain distance along screw mandrel axis direction.Therefore the knife rest, being arranged on small slide plate also moves certain distance.Therefore but owing to often there being gap between screw mandrel and nut, while rotating, can produce idle stroke (dial rotate and small slide plate do not slide).This situation is even more serious when rotating and reverse exchange, during use, must at leisure scale be forwarded to desired position.If careless several lattice that rotate, definitely can not directly return the lattice number turning simply more more, must return round about whole idle strokes, then forward scale to needed tram.Because gap causes the existence of idle stroke, make small slide plate control the precision of lathe tool length feed lower, and the control accuracy of lathe small slide plate is 0.05mm at present.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of device that can improve lathe feed precision, can effectively improve the precision that small slide plate is controlled lathe tool length feed.
The utility model is achieved through the following technical solutions:
Can improve a device for lathe feed precision, comprise small slide plate, rotating disk, between described small slide plate and rotating disk, be provided with displacement measuring device, described displacement measuring device comprises and is fixed on the main scale in sabot and is fixed on the vernier on small slide plate.
The further improvement project of the utility model is, has been bolted to connection main scale bracing frame on described rotating disk, and the two ends of main scale bracing frame are provided with a main scale holddown groove, and the two ends of described main scale are placed in main scale holddown groove, are screwed.
The utility model further improvement project is, has been bolted to connection vernier bracing frame on described small slide plate, and vernier bracing frame is provided with vernier holddown groove, and described vernier is placed in vernier holddown groove, is screwed.
The utility model further improvement project is, described main scale be take millimeter as unit, has 50 lattices on vernier, and the certainty of measurement of displacement measuring device is 0.02mm, between vernier and main scale, be provided with a spring leaf, utilize the elastic force of spring leaf that vernier and blade are close to.
The utility model further improvement project is that described vernier bracing frame and small slide plate are provided with locating hole, are inserted with alignment pin in locating hole.
Compared with prior art, tool has the following advantages the utility model:
The utility model is simple in structure, and the use of displacement measuring device make the control accuracy of small slide plate become 0.02mm from 0.05mm, and when small slide plate makes lathe tool length feed, the depth of cut is reflected on displacement measuring device immediately.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises small slide plate 1, rotating disk 7, between described small slide plate 1 and rotating disk 7, be provided with displacement measuring device, described displacement measuring device comprises the main scale 9 being fixed in sabot 7 and is fixed on the vernier 4 on small slide plate 1, on described rotating disk 7, be bolted to connection main scale bracing frame 8, the two ends of main scale bracing frame 8 are provided with a main scale holddown groove 10, the two ends of described main scale 9 are placed in main scale holddown groove 10, fixing with screw 11, on described small slide plate 1, be bolted to connection vernier bracing frame 2, vernier bracing frame 2 is provided with vernier holddown groove 5, described vernier 4 is placed in vernier holddown groove 5, fixing with screw 6, described main scale 9 be take millimeter as unit, on vernier 4, there are 50 lattices, certainty of measurement is 0.02mm, between vernier 4 and main scale 9, be provided with a spring leaf, utilize the elastic force of spring leaf that vernier and blade are close to, described vernier bracing frame 2 is provided with locating hole 3 with small slide plate 1, in locating hole 3, be inserted with alignment pin.
During use, by alignment pin, adjust after the relative position of vernier bracing frame 2 and small slide plate 1, with bolt, be fixed, and main scale bracing frame 8 is fixedly connected with rotating disk 7, then, main scale 9 is placed in to main scale holddown groove 10, fixing with screw 11, and vernier 4 is placed in vernier holddown groove 5, fixing with screw 6, although the gap between screw mandrel and nut still exists, during rotation, can produce idle stroke (dial rotate and small slide plate do not slide), but vernier 4 and main scale 9 are only when the depth of cut really produces, just can mutually slide, the depth of cut is reflected on displacement measuring device immediately.And the certainty of measurement of displacement measuring device is 0.02mm, the control accuracy of 1 pair of depth of cut of small slide plate is improved.
