Abstract
The invention discloses a novel tip mechanism with a strong tightly-pressing function for a machine tool. A proper amount of liquid plastic is filled in blind hole end parts of a tip and a tip body; a piston is arranged on the tip mechanism and a handle of a rotary tip is provided with a bearing, and then an outer ring of the bearing is arranged at an orifice part of a tip carrier; and a gland bush, an oil injection nozzle and an adjusting bolt are arranged on the tip mechanism, wherein the tail a of the tip carrier is made into a corresponding taper to match with an external member of a tail seat conveniently. The rotary tip is arranged in a hole formed in the middle of the tip body through the bearing on the handle of the rotary tip, the end part of the handle of the rotary tip contacts a main piston, and a given amount of the liquid plastic is filled in a space closed by the main piston and the tip body, so when a workpiece generates certain heat, the rotary tip compresses the liquid plastic through the main piston; and because the liquid plastic has certain compression amount, the liquid plastic can make up the heated elongation of the workpiece.
Description
Technical field
It is top to the present invention relates to a kind of lathe, particularly a kind of tip mechanism of novel lathe strong tightly-pressing function.Belong to the machine tool technical field.
Background technology
Top is standing instrument in the lathe, and it is that workpiece is played a supportive role on the one hand, plays the benchmark location on the other hand.At present top have a back dead centre, live center, and hydraulic pressure is top etc.In all these are top, in the production of reality, all there is different defective more or less.Back dead centre low price simple in structure, but because and have relative motion between the workpiece, the frictional force and the frictional heat that are produced are bigger, make location benchmark wearing and tearing easily, reduce the precision of workpiece processing.It is not strong that above-mentioned in addition two kinds of structures top also exists clamping force, clamping force is regulated the defective of inconvenience in the work, be not suitable for producing in batches, the processing of heavy workpiece etc. are though the top function that has temperature-compensating to a certain extent of hydraulic pressure is easy to use, clamping force is powerful, but whole system is comparatively complicated, and cost is higher, inconvenient maintenance.
Summary of the invention
The objective of the invention is to: a kind of tip mechanism of novel lathe strong tightly-pressing function is provided, makes its top simple use easy to maintenance, can effectively overcome the above-mentioned defective of existing top existence.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of tip mechanism of novel lathe strong tightly-pressing function, it is by live centre, top body, bearing, spacer, piston, liquid plastics, adjustment screw, pump nozzle, and composition such as gland.It is characterized in that: live centre is installed in the middle hole of top supporting body by the bearing on its handle, the end of live centre handle contacts with main piston, in the space that main piston and top supporting body sealed, inject the liquid plastics of some, so after workpiece produces certain heat, live centre compresses liquid plastics by main piston, because the fluidity grog has certain decrement, so can remedy the elongation that workpiece is heated.In addition for the ease of workpiece is produced stronger clamping top power, and to the adjustment of thrust, having the Screw hole in the suitable place of the locus at liquid plastics place communicates with the external world, be screwed into adjustment screw in the screw hole, earlier workpiece being carried out common mode during work clamps, tightening adjustment screw as required afterwards, making the liquid plastics compression, live centre is being clamped workpiece by piston.
Beneficial effect: because live centre has the axially movable free degree in this cover mechanism, can compensate the elongation that workpiece Yin Wendu raises and produced to a certain extent, overcome the quality problems that therefore might produce, simultaneously because the mode that adopts adjustment screw that liquid plastics is compressed, so not only can produce bigger clamping force, clamping force is regulated also more convenient simultaneously.
Description of drawings
Accompanying drawing is a schematic diagram of the present invention.
Shown in the figure: 1, live centre; 2, top body; 3, bearing; 4, spacer; 5, piston; 6, liquid plastics; 7, adjustment screw; 8, pump nozzle; 9, gland; 10, top carrier.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done specific description.
An amount of liquid plastics (6) is filled into the blind bore end of top (1), top body (2), after the piston (5) of then packing into is loaded onto bearing (3) with the shank of live centre, be installed to the position, aperture of top carrier (10) with the outer ring of bearing, load onto gland (9), pump nozzle (8) and adjustment screw (7) get final product, wherein the afterbody a of top carrier makes corresponding tapering, so that match with the external member of tailstock.Live centre (1) is installed in the middle hole of top body (2) by the bearing on its handle (3), the end of live centre (1) handle contacts with main piston, in the space that main piston (5) and top body (2) are sealed, inject the liquid plastics (6) of some, so after workpiece produces certain heat, live centre (1) is by main piston (5) compression liquid plastics, because liquid plastics (6) has certain decrement, so can remedy the elongation that workpiece is heated.In addition for the ease of workpiece is produced stronger clamping top power, and to the adjustment of thrust, having the Screw hole in the suitable place of the locus at liquid plastics (6) place communicates with the external world, be screwed into adjustment screw (7) in the screw hole, earlier workpiece being carried out common mode during work clamps, tightening adjustment screw (7) as required afterwards, making liquid plastics (6) compression, live centre (1) is being clamped workpiece by piston (5).
Claims (3)
1. the tip mechanism of a novel lathe strong tightly-pressing function, it is characterized in that: the blind bore end that an amount of liquid plastics (6) is filled into top (1), top body (2), after the piston (5) of then packing into is loaded onto bearing (3) with the shank of live centre, be installed to the position, aperture of top carrier (10) with the outer ring of bearing, load onto gland (9), pump nozzle (8) and adjustment screw (7) get final product, and wherein the afterbody a of top carrier makes corresponding tapering, so that match with the external member of tailstock.
2. the tip mechanism of a kind of novel lathe strong tightly-pressing function according to claim 1, it is characterized in that: live centre (1) is installed in the middle hole of top body (2) by the bearing on its handle (3), the end of live centre (1) handle contacts with main piston, in the space that main piston (5) and top body (2) are sealed, inject the liquid plastics (6) of some, so after workpiece produces certain heat, live centre (1) is by main piston (5) compression liquid plastics, because liquid plastics (6) has certain decrement, so can remedy the elongation that workpiece is heated.
3. the tip mechanism of a kind of novel lathe strong tightly-pressing function according to claim 1 and 2, it is characterized in that: in addition for the ease of workpiece is produced stronger clamping top power, and to the adjustment of thrust, having the Screw hole in the suitable place of the locus at liquid plastics (6) place communicates with the external world, be screwed into adjustment screw (7) in the screw hole, earlier workpiece being carried out common mode during work clamps, tightening adjustment screw (7) as required afterwards, make liquid plastics (6) compression, live centre (1) is clamped workpiece by piston (5).
