Abstract

The utility model discloses a special center support for manufacturing big-diameter long shaft, and is provided to overcome the shortages that the three claws of center support of the prior common lathe are made from tin-bronze material, and have a large touch area to the big-diameter long shaft, and the friction is big to wear down the bronze bar, and the three claws are of low work efficiency. The utility model comprises an upper base, a lower base, and two supporting sleeves arranged on the lower base and a supporting sleeve arranged at the top of the upper base; the supporting sleeves face the center with adjustable length; supporting claws are respectively arranged at the facing centers of the supporting sleeves; the supporting claws are trolley which can roll on the long rotary shaft supported. Because the three claws of the long supported shaft on the center support are provided with trolleys, when the center support works, the trolleys roll on the outer circumference of the rotary long shaft for a touch support, the friction between the supporting claws and the outer circumference of the shaft is reduced without material wastage; the utility model is of low manufacturing cost, high work efficiency; at the same time, the supporting claws are of convenient operation, maintenance, and low maintenance cost; when the trolleys after long-time use are damaged, the trolleys need only to be replaced.

Description

The major diameter major axis is processed special-purpose centre frame
Technical field
The utility model belongs to machine tool accessories, specifically a kind of centre frame that processing major axis type component uses on lathe.
Background technology
Engine lathe has generally all been assisted centre frame, is used for the secondary process of thin and long shafts parts.The auxilliary centre frame that has of described engine lathe all is that the general slender axles of certain class machined into are designed.The machinery that uses on the port and pier is large-scale mostly, and that major axis base part diameter mechanically has is little, length has shortly, but more is diameter super large, length overlength.Big machinery will be to the wearing and tearing of the part on it axle base part place under repair or replacing when repairing, and major axis must be used the centre frame secondary process on lathe.For general repair plant, assort the lathe and the centre frame that can adapt to the major axis instructions for use fully, it is too big to inject capital into; Even if moreover assorted, also can be because of the few long-term idle waste that cause of access times.For engine lathe, the scope of processing large diameter major axis base part is wider, but the centre frame that is disposed just can not all adapt to.Traditional centre frame, its termination of supporting three pawls of usefulness all is to adopt fixing tin bronze material to make, and the pawl of tin bronze is coupling with large diameter that to touch area big, and frictional force is big generates heat easily, not only the loss copper rod is many, and causes inefficiency greatly because of frictional force.
The utility model content
Technical problem to be solved in the utility model is, the three-jaw that overcomes existing centre frame that engine lathe is joined adopts fixing tin bronze material, be coupling with large diameter that to touch area big, frictional force lossy copper rod, the shortcoming that work efficiency is low provide a kind of major diameter major axis to process special-purpose centre frame.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the lathe centre frame comprises following, the seat of honour, and be installed in down two, a subtend center at top, the seat of honour on the seat and the support set of adjustable length, subtend center-side at support set is separately installed with support claw, the roller of described support claw for rolling on the supported major axis diameter of axle that rotates.
The utility model also has following technical characterictic:
Described roller is a ball bearing;
The installation of described ball bearing, be the subtend centre frame center-side at support set, the direction of suitable support set is installed with support, and bracket end is provided with the groove along the support set direction, bearing pin is horizontally through groove and is fixed in the both sides of groove, and bearing is fixedly mounted in groove on the diameter of axle of bearing pin.
Advantage of the present utility model and good effect are, because three pawl ends of centre frame upper support major axis, be separately installed with the roller that can on the supported major axis that rotates, roll, during work, roller is done the contact support of rolling on the major axis periphery that rotates, reduced the frictional force between centre frame upper support pawl and axle periphery, not consumable material, cost of manufacture is low, the work efficiency height; Use, maintenance and the easy maintenance of while support claw, maintenance cost is low, after long-term use roller damages, as long as it is changed.
Description of drawings
Fig. 1 looks schematic diagram for master of the present utility model;
Fig. 2 is that the A of Fig. 1 is to partial view.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, the lathe centre frame comprises following 1, links the seat of honour 7 on following 1, and the leading screw 6 that is installed in down seat 1 both sides and 7 tops, the seat of honour, subtend centre frame center, and leading screw 6 is at the inner support claw of installing of centre frame.
The installation of leading screw 6, it is the hole that 7 positions that support claws are installed are provided with subtend centre frame center at following 1 and the seat of honour, the outer end at the decentre frame center in hole is equipped with cover 8, the inner to the center in hole is equipped with tapped support set 2, the outer end bearing of leading screw 6 is installed in the cover 8, and the inner is screwed in the internal thread on the support set 2; The subtend center-side of support set 2 is separately installed with the support claw that can be supported on the processed major axis external diameter, the roller of described support claw for rolling on the supported axle diameter of axle that rotates.
The simplification of making for roller and use in wearability good, described roller is with can being the rolling bearing of having bought on market 3.
The installation of described rolling bearing 3, it is the inner at the subtend centre frame center of support set 2, direction along support set 2 is installed with support 5 (referring to Fig. 2), the spindle nose of the decentre frame center-side of support 5, be fixedly mounted in the hole of support set 2 terminations, the other end is provided with the groove 5.1 along support set 2 directions, and bearing pin 4 is horizontally through groove 5.1, it supports the diameter of axle and is fixed on the support 5 on groove 5.1 both sides, and bearing 3 settings are installed in the groove 5.1 and are fixedly installed on the medium axle diameter of bearing pin 4.
