Abstract
The utility model discloses a tailstock suitable for a common horizontal type machine tool, which is composed of a rolling wheel assembly and a floating device. Each sliding surface of the original tailstock base plate of the machine tool needs only to be added with 2 to 5 floating rolling devices, and the original sliding friction between the tailstock and a machine frame guide rail can be changed into pure rolling friction; therefore, abrasion can not be generated on the guide rail and the sliding surface of the tailstock base plate, and the using period of the machine tool can be extended. The utility model has the advantages of simple structure, low cost, and flexible operation; the utility model is widely suitable for the machine tool reformation and manufacture in mechanical manufacture industries.
Description
The utility model relates to a kind of lathe slip tailstock, particularly relates to the floating tourelle on a kind of horizontal machine tool slip tailstock.
The slip tailstock of existing common horizontal machine tool is to apply bigger thrust by the operator or pulling force is realized moving on bed ways.Because tailstock often moves on guide rail with the length of part to be processed, thereby suitable effort not only during mobile tailstock, operator's labour intensity is big, and along with the prolongation of time, sliding surface weares and teares gradually, causes the tailstock center to descend, the equipment precision forfeiture.Recover service precision, then must stop production and repair, workload is big and the cycle is long.The purpose of this utility model is to overcome in the prior art horizontal machine tool slip tailstock and moves this weak point of difficulty, and a kind of floating tourelle that is applicable to simple in structure, easy to use and the bed ways not easy to wear and the slide of tail stock bottom of general common horizontal machine tool slip tailstock is provided.
Realize that the technical solution of the utility model is perpendicular to 2 to 5 through holes of sliding surface direction processing on each sliding surface of horizontal machine tool slide of tail stock bottom, close its position: at the two ends of each sliding surface a through hole is arranged respectively, other through hole is arranged between these two through holes, the floating tourelle of one cover all is installed in each through hole, and this floating tourelle is made of roll wheel assembly and the floating installation that is positioned at roll wheel assembly top.By placing one group of tailstock tool base plate sliding surface through hole floating tourelle to realize pure rolling between tailstock tool and bed ways, thereby reach the purpose of this utility model.
The structure and the function of roll wheel assembly and floating installation are as follows in the floating tourelle:
1 roll wheel assembly: roll wheel assembly is installed in the turning rolls upper support hole by the axle that roller is arranged and constitutes, it is the critical piece of realizing replacing sliding friction with rolling friction, when floating installation floats tailstock automatically, when each sliding surface and bed ways are thrown off, only with hand is gently dialled tailstock, roller just begins to roll, and tailstock is steadily moved along guide rail, thereby realizes replacing sliding friction with rolling friction.2 floating installations: spring, packing ring, the adjustment screw of floating installation for being arranged in order on roll wheel assembly turning rolls top.Its effect is when the tailstock set lever is in releasing orientation tailstock to be floated, and this moment, tailstock and guide rail were thrown off, and by the support of roller, guarantees that bed ways are not worn when mobile.
Accompanying drawing 1 has provided the cutaway view of one group of floating tourelle.
Among the figure:
(1) bed ways, (2) fixed head, (3) axle, (4) roller,
(5) turning rolls, (6) spring, (7) packing ring, (8) adjustment screw,
(9) tailstock body, (10) slide of tail stock bottom, (11) packing ring,
(12) screw,
The embodiment that provides below in conjunction with accompanying drawing further specifies the CONSTRUCTED SPECIFICATION of the present utility model and the course of work.
Accompanying drawing has provided the details of a cover floating tourelle of the utility model after repacking on the common horizontal machine tool slip tailstock.On horizontal machine tool slide of tail stock bottom (10) sliding surface, be processed with through hole perpendicular to the sliding surface direction, with roller (4) and packing ring (11) spacer sleeve on axle (3), and axle (3) packed into form roll wheel assembly in the supported hole of turning rolls (5), roll wheel assembly places through hole sliding surface one side, and roller (3) is towards sliding surface.Roll wheel assembly is fixing spacing by fixed head (2), and fixed head (2) is fixed in the sliding surface by screw (12), and its bottom surface and tailstock guide are in same plane.On mounted roll wheel assembly turning rolls top, the spring (6) of packing into successively, packing ring (7), adjustment screw (8) form floating installation, adjust the pretightning force of spring (6) by adjustment screw (8), and when pretightning force during greater than tailstock gravity, tailstock floats.The adjustment of spring (6) pretightning force is only carried out when mounted tailstock, needn't adjust in the use again.
Aforesaid through hole and floating tourelle have six in the present embodiment, lay respectively at the rear and front end of three sliding surfaces on the horizontal machine tool slip slide of tail stock bottom, form one group of floating tourelle, finish the floating task of rolling of lathe slip tailstock that makes jointly.
The course of work of the present utility model is as follows: when tailstock is in running order, utilize former set lever that tailstock is locked, in roller (4) the retraction tailstock sliding surface, form tailstock and the original combining form of bed ways at this moment.When tailstock work finishes, set lever is when releasing orientation, and tailstock floats automatically, and each sliding surface and bed ways are thrown off, and only has 6 roller fulcrums to support, and dials tailstock with have gentle hands, and roller (4) just rolls, and tailstock then steadily moves along guide rail.Tailstock moves to a certain position fixedly the time, handles set lever, roller (4) homing, and entire work process finishes.
Floating tourelle of the present utility model has only just been realized pure rolling friction between tailstock and bedstead guide rail making slide of tail stock bottom and guide rail not produce wearing and tearing increasing a small amount of part on the former tailstock; Tailstock center after the repacking keeps contour with the head of a bed alignment of shafts all the time, the operation light and flexible.This tailstock is simple in structure, and cost is low, and the equipment medium-capital overhauling of making has reduced sizable workload and prolonged the lathe life cycle, also brings great convenience to the operator simultaneously, can be widely used in the machine reformation and manufacturing of machine industry.
Claims (3)
1, a kind of slip tailstock of common horizontal machine tool, comprise bed ways (1), tailstock body (9), slide of tail stock bottom (10), it is characterized in that on each sliding surface of slide of tail stock bottom (10), 2 to 5 through holes being arranged perpendicular to the sliding surface direction, the floating tourelle of one cover is all arranged in each through hole, and this floating tourelle is made of roll wheel assembly and the floating installation that is positioned at roll wheel assembly top.
2, slip tailstock as claimed in claim 1 is characterized in that roll wheel assembly is installed in turning rolls (5) the upper support hole and is constituted by the axle (3) that roller (4) is arranged.
