Abstract
The utility model discloses a kind of novel follow-rest support claw, belong to field of machining, it is characterized in that: comprise bearing pin (1), rolling bearing (2), screw (3), packing ring (4) and support (5), wherein rolling bearing (2) has two, bearing pin (1) is through rolling bearing (2) and packing ring (4), and bearing pin (1) is fixed on support (5) by screw (3); After using this support claw when workpiece rotates, the together rotary motion of rolling bearing and workpiece, become sliding friction of the prior art into rolling friction, reduce coefficient of friction, reduce frictional force, decrease wearing and tearing, simultaneously also less to the infringement of workpiece, solve the wear problem improving front support pawl front end spheroidal graphite cast-iron; Adopt double rolling bearing enlarged contact areas, enough actuating pressures can be produced to workpiece, ensure required precision during turning, improve working (machining) efficiency; This support claw also extends on centre frame, and processing is simple, and cost is low, is convenient to promote.
Description
Technical field
The utility model belongs to field of machining, particularly relates to a kind of novel follow-rest support claw.
Background technology
Follow-rest is the annex of lathe, is generally fixed on lathe saddle, follows and move after lathe tool during turning, bear the bite acted on workpiece, slender axles poor rigidity, turning is more difficult, during the slender axles of particularly turning indirect cutter in not allowing, follow-rest should be used to be installed; As adopted follow-rest to support, can its strength and stiffness be strengthened, effectively prevent the flexural deformation of workpiece, ensure crudy; But in turner is produced, the wearing and tearing of follow-rest support claw are one of common faults, and what follow-rest was conventional has two support claw follow-rests and three-jaw follow-rest.
The material of the support claw of three-jaw follow-rest is generally spheroidal graphite cast-iron, and the material of machining shaft is generally common straightcarbon steel, Fine Steel Casting iron, steel alloy etc.; As support claw, spheroidal graphite cast-iron directly contacts with above-mentioned material, because the coefficient of friction between cast iron and steel is larger, the major axis High Rotation Speed of processing causes the heavy wear of support claw, before support claw does not wear and tear, its top is close to taper, and the rear indent of wearing and tearing is serious, constantly waters oily cooling and lubricating and the position constantly adjusting follow-rest support claw at present in turner is produced in order to the wearing and tearing tackling this support claw mainly adopt, to ensure the axiality with workpiece, avoid the generation of form error; But this still cannot be avoided the continuous wearing and tearing of spheroidal graphite cast-iron support claw, and bring great inconvenience to turner production; The wearing and tearing of each support claw are different, therefore will often adjust when turning, and have impact on the machining accuracy of axial workpiece to a certain extent, even cause axial workpiece to scrap.
Summary of the invention
The purpose of this utility model there is provided a kind of novel follow-rest support claw, solves support claw in prior art and is easily worn thus causes the problem that Machining of Shaft-type Parts precision is low.
In order to achieve the above object, the utility model by the following technical solutions, a kind of novel follow-rest support claw, comprise bearing pin, rolling bearing, screw, packing ring and support, wherein rolling bearing has two, and bearing pin is through rolling bearing and packing ring, and bearing pin is fixed by screws on support.
A kind of novel follow-rest support claw, wherein two rolling bearings are arranged at support claw foremost, directly contact with shaft-like workpiece.
The beneficial effects of the utility model are: after using this support claw when workpiece rotates, the together rotary motion of rolling bearing and workpiece, become sliding friction of the prior art into rolling friction, reduce coefficient of friction, reduce frictional force, decrease wearing and tearing, simultaneously also less to the infringement of workpiece, solve the wear problem improving front support pawl front end spheroidal graphite cast-iron; Adopt double rolling bearing enlarged contact areas, enough actuating pressures can be produced to workpiece, ensure required precision during turning, improve working (machining) efficiency; This support claw also extends on centre frame, and processing is simple, and cost is low, is convenient to promote.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of novel follow-rest support claw.
Fig. 2 is the structural representation that a kind of novel follow-rest support claw is arranged in follow-rest quill.
In figure, 1, bearing pin, 2, rolling bearing, 3, screw, 4, packing ring, 5, support, 6, support claw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further, as shown in fig. 1, a kind of novel follow-rest support claw, comprise bearing pin 1, rolling bearing 2, screw 3, packing ring 4 and support 5, wherein rolling bearing 2 has two, bearing pin 1 is through rolling bearing 2 and packing ring 4, and bearing pin 1 is fixed on support 5 by screw 3; Bearing pin 1 ensure that rolling bearing 2 stablizing in lengthwise position, and packing ring 4 ensures rolling bearing 2 not double swerve.
A kind of novel follow-rest support claw, as in Fig. 1 and as shown in Fig. 2, the spheroidal graphite cast-iron arranged before two rolling bearings 2 replace with absorption surface in support claw 6 front end directly contacts with shaft-like workpiece, support claw 6 and the common holding workpiece of cutter; When workpiece rotates, rolling bearing 2 and workpiece together rotary motion, becoming prior art sliding friction is rolling friction, reduce coefficient of friction, reduce frictional force, decrease wearing and tearing, simultaneously also less to the infringement of workpiece, solve the wear problem improving front support pawl front end spheroidal graphite cast-iron; Adopt double rolling bearing 2 enlarged contact areas, enough actuating pressures can be produced to workpiece, ensure required precision during turning; Rolling bearing 2 and workpiece rotate jointly, wear and tear minimum, Work piece high-speed can be allowed to rotate, high-speed turning thin and long shafts part is achieved.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
Claims (2)
