Abstract
The utility model discloses a centre frame of roll lathe, comprising an annular frame; an inner ring of the annular frame is provided with three radial retractable support rods by means of trisection; the annular frame includes an upper frame and a lower frame; ends of the upper frame and the lower frame are rotatably interconnected by a rotating shaft while the other ends are openable and closable and are relatively fixed by a bolt; a cylindrical nylon support claw is fixed to the inner end of each support rod; the annular frame of the centre frame of roll lathe according to the utility model can be divided into upper and lower frames, which can be opened from one end; thus, when the roll is required to be placed the upper frame can be firstly opened and then put down, followed by screwing the bolt, thereby facilitating the operation; on one hand, the cylindrical nylon support claw has large contact surface with the roll and firmer grasp; on the other hand, the nylon has good wearing resistance and long service life.
Description
Technical field
The utility model relates to the lathe equipments technical field, particularly a kind of roll lathe centre frame.
Background technology
The lathe of existing processing roll, its centre frame support claw material is the manufacturings of copper and cast iron, when processing roll, because roll weight is big, the support claw serious wear, cause the roll center to move down, product does not reach specification requirement, and qualification rate is low, and the replacing of support claw is rapid, increase processing cost, influenced normally carrying out of producing.
Chinese patent literature CN 2547441Y discloses a kind of " lathe centre frame ", it comprises round bearing, in the hole that is provided with radially on the round bearing radially adjustable support bar is housed, support claw is equipped with in support bar the inner, the support claw front end has a groove, one roller is housed in the groove, and the part roller exposes from groove, and roller wheel shaft is parallel with the circle central axis of round bearing.This centre frame is by the single roller back-up roll on its inner support bar, because the contact-making surface of single roller and roll is less and each roller between do not get in touch, each roller pressure of the centre frame of this structure is bigger, rigidity and stability are limited, round bearing can not be opened simultaneously, is inconvenient to place roll.
The utility model content
The purpose of this utility model provides a kind of convenient roll, roll lathe centre frame that the support claw wearability is good placed.
The technical scheme that realizes the utility model purpose is a kind of rod lathe centre frame that rolls, and comprises toroidal frame, and the inner ring trisection of toroidal frame is provided with three radially telescopic support bars; Described toroidal frame comprises puts on the shelf and undercarriage, and the two end is rotationally connected by rotating shaft, but other end folding, and by the bolt relative fixed; All be fixed with columniform nylon support claw on the inner of described every support bar.
The roll lathe centre frame also comprises three lock pins; Described three lock pins correspondence respectively are arranged on the support bar.
The roll lathe centre frame also comprises base; Described base is fixedlyed connected with the lower surface of the undercarriage of toroidal frame, and base is provided with groove, is provided with in the groove to be used for and the fixing bolt of lathe.
Described base also comprises and is positioned at the reinforcements of fixedlying connected with the lower surface of undercarriage toroidal frame the groove both sides.
The utlity model has positive good effect: the toroidal frame of roll lathe centre frame of the present utility model is divided into undercarriage, can open from an end, just can open putting on the shelf earlier when need placing roll like this, place afterwards putting down and put on the shelf, and tight a bolt, made things convenient for operation.Columniform nylon support claw is on the one hand with to roll the rod contact-making surface big, grasps more firmly, and on the other hand, the nylon wearability is good, long service life.On every support bar, lock pin is set, can better limits the position of support bar, guarantee in rolling the process of rod the location of support claw breaker roll.The groove of base and the effect of reinforcement are to guarantee the weight that alleviates base in Beijing South Maxpower Technology Co. Ltd's power of taking advantage of of base also to make things convenient for removing and installing of centre frame and lathe simultaneously.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is a kind of structural representation of the present utility model.
Label is in the accompanying drawing: toroidal frame 1, put 11 on the shelf, undercarriage 12, rotating shaft 13, bolt 14, support bar 2, nylon support claw 3, lock pin 4, base 5, groove 51, bolt 52, reinforcement 53.
The specific embodiment
(embodiment 1)
See Fig. 1, a kind of rod lathe centre frame that rolls of present embodiment comprises toroidal frame 1, and the inner ring trisection of toroidal frame 1 is provided with three radially telescopic support bars 2; Described toroidal frame 1 comprises puts 11 and undercarriage 12 on the shelf, and the two end is rotationally connected by rotating shaft 13, but other end folding, and by bolt 14 relative fixed; All be fixed with columniform nylon support claw 3 on the inner of described every support bar 2.On the every support bar 2 also respectively correspondence be provided with a lock pin 4.Base 5 is fixedlyed connected with the lower surface of the undercarriage 12 of toroidal frame 1, and base 5 is provided with groove 51, is provided with in the groove 51 to be used for and the fixing bolt 52 of lathe.Base 5 also comprises and is positioned at the reinforcements 53 of fixedlying connected with the lower surface of undercarriage 12 toroidal frame 1 groove 51 both sides.
Should be appreciated that specific embodiment described above only is used to explain the utility model, and be not used in qualification the utility model.Conspicuous variation of being extended out by spirit of the present utility model or change still are among the protection domain of the present utility model.
