Description

Three axle ball extrusion clamps
Technical field
The present invention three axle ball extrusion clamp belongs to mechanical field, is a kind of for the cylindrical extruding of longaxones parts, grinding Fixture.
Background technology
With scientific and technical development, the processing of present machine components is to precision and roughness requirements more and more higher.Major axis The processing of class part is always a very big difficult problem, and lathe process common first is easily deformed, and is difficult to meet wanting of roughness Ask, and the length increase with longaxones parts is difficult to be placed on being ground on grinding machine.Conventional solutions are direct Polished with fine gtinding gauze, the controllability of quality is poor, and roughness is difficult to meet use requirement, dangerous in regular job Coefficient is very big, if not noting being susceptible to industrial accident.
The appearance of extrusion process, largely solves the problems, such as above-mentioned, is not only able to ensure the degree of accuracy of processing, long Axial workpiece is not susceptible to deform, and can guarantee that enough use roughness.
Content of the invention
The purpose of the present invention is to provide a kind of three axle ball extrusion clamps for above-mentioned weak point, solid by lathe saddle Determining present clip is in that left and right average rate moves, and three roller bearings along 360 ° of even circumferential distributions choke longaxones parts, move this Fixture and rotation longaxones parts, both collective effect extruding, finally process the part meeting precision and roughness requirements.
The present invention takes technical scheme below to realize:
Three axle ball extrusion clamps include support, roller bearing and tail folder, upper bracket that described support includes being sequentially connected, right support, Lower carriage and left socle, form hexagon;Left socle and right support are located at lower carriage both sides, left socle and the one of right support respectively End is connected with lower carriage, is equipped with location hole at the middle part of left socle and right support, left socle is equal with the other end of right support Have shaft hole;Left socle is connected with the arranged on left and right sides of upper bracket by shaft hole respectively with right support;Upper bracket is divided into three Section, stage casing is horizontal, and two sections of left and right oliquely downward extends from stage casing respectively, and three sections of compositions are trapezoidal;Middle part in upper bracket stage casing Have location hole, the left and right two ends of upper bracket have fixing hole, the shaft hole of described fixing hole and left socle and right support Overlap, fixed by bearing pin;Tail folder is connected with the fixing hole of right support by bearing pin;Three roller bearings be each passed through left socle, Right support and the middle part of upper bracket, and fixation is installed by location hole;Three roller bearings are distributed along 360 ° of even circumferentials, by major axis class Part extrudes to center.
Described roller bearing includes axostylus axostyle, axle sleeve and ball;Axle sleeve inner hollow, upper, open end is provided with female thread, and bottom is opened There is axle sleeve hole;Inside axostylus axostyle insertion axle sleeve, axostylus axostyle bottom is provided with draw-in groove;Axostylus axostyle is pushed down by thread bush, axostylus axostyle is interior with axle sleeve Screw thread cooperation is fixed;Bearing is located on the draw-in groove in the middle of axostylus axostyle, and is relatively fixed with axostylus axostyle by alignment pin;Ball is located at bearing Lower section, expose from the axle sleeve hole of axle sleeve bottom, bearing and ball can be freely rotatable.
The described fixing hole positioned at upper bracket both sides and shaft hole have certain bias, that is, not on a horizontal line, just On the knife rest being arranged on lathe.
Described axostylus axostyle top is provided with quarter chi, stretches into the depth of support in order to measure roller bearing.
The length that axostylus axostyle gos deep into axle sleeve can be adjusted, and passes through the location hole on support to withstand axostylus axostyle by bolt, thus fixing Axostylus axostyle stretches into the length of axle sleeve.
Described alignment pin external diameter is consistent with brearing bore diameter, and alignment pin is mutually fixed with bearing through axostylus axostyle with axle sleeve.
The axle sleeve hole of described axle sleeve bottom is conical surface perforate, and the height that ball exposes axle sleeve hole is the 1/5 of ball diameter.
Invention advantage: it is in that left and right average rate moves that the present invention mainly fixes this fixture by lathe saddle, this fixture three Roller bearing along 360 ° of even circumferential distributions chokes longaxones parts, moves this fixture and rotation longaxones parts, both make jointly With extruding, finally process the part meeting precision and roughness requirements.Wherein core part is roller bearing, according to quarter chi scalable Roller bearing disclosure satisfy that the Excircle machining of different parts.360 ° are distributed in reality processing and can play uniformly very well simultaneously Support, will not cause the scale error of part.The present invention fundamentally solves the polishing of Conventional solutions fine gtinding gauze Processing mode, different parts adopt different rotating speeds coupling pressurization, quality whole process is controlled, and the hidden of industrial accident does not occur Suffer from.The course of processing can guarantee that processing degree of accuracy and roughness, high working efficiency, be worth of widely use very much.
