Description
Technical field
The invention belongs to a kind of bearing assemble device, the device using while relating generally to a kind of large-scale, super-huge type tapered roller bearing assembling.
Background technique
Known, tapered roller bearing adopts the retainer of steel plate punched material, all adopts the processing technology of retainer fenestra microcephaly's the outside micro-expansion of root at present.The retainer of this processes is in the time of assembling, can facilitate roller to pack smoothly inner ring raceway into, the scuffing of colliding with simultaneously that can avoid again roller surface, raceway face to produce, inner assembly after assembling, then by angle and the size of shrinking die, gland and press machine retainer fenestra microcephaly's root is retracted to drawing requirement.
While assembling for medium and small (bearing bore diameter size is below 200mm) tapered roller bearing, use the mould of said structure not have any problem, but while assembling, use the mould of said structure will have very serious quality problems for large-scale, super-huge type tapered roller bearing.Because large-scale, super-huge (bearing bore diameter size is more than 200mm) tapered roller bearing is all larger, inner assembly, contraction die and gland after assembling do not have again positioning tool, in the time that depressing, press machine very easily produces skewness, make inner assembly, shrink die and gland discontinuity equalization, produce retainer and weigh phenomenon wounded, thereby cause product rejection; Due to large-scale, super-huge type tapered roller bearing is all larger, add inner assembly after assembling, shrink die and gland weight very heavy, therefore workman's labor intensity is larger, labour cost and manufacture cost are larger.
Summary of the invention
The object of this invention is to provide a kind of large-scale, super-huge type tapered roller bearing tool for assembling, it can improve the assembly performance of bearing, there is the features such as registration, die manufacturing cost simple to operate is cheap, the cycle is short, can greatly reduce labor intensity, enhance productivity.
Object of the present invention can adopt following technological scheme to realize: it comprises drift, worktable, pressing plate, pressure ring, die; Described worktable, pressing plate and pressure ring have the same center of circle, and pressing plate is arranged on lower portion of ram, and pressure ring is arranged on the bottom of pressing plate, and die is arranged on worktable top, relative with pressure ring, are evenly equipped with the depression identical with the tapered roller number of bearing in die.
Above described worktable, there is one group of concentric annular scrobicular ring a and the T-shaped groove of cross.
Above described pressing plate, have one group of concentric annular scrobicular ring b, be evenly distributed in counterbore a, through hole a and tapped hole, the through hole on pressing plate on counterbore a, through hole a and drift is joined brill; Pressing plate is fixed by socket head screw b and nut b and drift.
Described pressure ring is evenly distributed in corresponding counterbore b, through hole b, and the tapped hole on itself and pressing plate is joined brill, and pressure ring is fixing by socket head screw a and pressing plate bottom.
On described worktable, be provided with the cylinder ring for fixing die, be provided with T-shaped bolt on T-shaped groove, cylinder ring is by nut a and T-shaped being bolted on worktable.
The beneficial effect of the invention is: on table top, have the design of some concentric a annular scrobicular rings to facilitate the accurate location of the mould of different sizes, and T-shaped bolt can be put into from four direction, be taken out to the design of the T-shaped groove of cross easily, four T-shaped bolts, cylinder ring and a nuts play fixed mould.On hold-down plate surface, there is the design of some concentric b annular scrobicular rings to facilitate the accurate location of the pressure ring of different sizes, and four a counterbores and a through hole on pressing plate, must join and bore to ensure to be connected precision with the through hole on drift, six tapped holes on pressing plate, must with pressure ring on six b counterbores and b through hole join brill, to ensure to connect precision.Pressure ring is evenly distributed in six counterbore b and through hole b, and the internal diameter of pressure ring is greater than inner ring large-flange external diameter, and this design can be pressed on retainer large end face pressure ring stably, simultaneously again not with the large-flange external diameter interference of inner ring.In the die that contraction retainer is used, be evenly equipped with several depressions identical with the tapered roller number of bearing, can easily the inner assembly of tapered roller bearing be put into die.
Working principle of the present invention: first by pressing plate with four b socket head screws by the through hole on a counterbore, a through hole and drift, be connected and fixed with b nut; Again pressure ring is connected and fixed by the tapped hole of joining brill on b counterbore and b through hole and pressing plate with six a socket head screws; Die lies on the central position of table top, and four T-shaped bolts penetrate the T-shaped groove of cross from four direction respectively, fixes respectively with four cylinder rings and a nut; Only the inner assembly assembling need be put into die successively, start press machine, pressure ring is pressed on retainer large end face stably, retainer fenestra microcephaly's root can be retracted to angle and the size of drawing requirement.
This structure frock, according to the size of bearing size, only needs to change corresponding die and pressure ring, and b counterbore and b through hole on tapped hole and pressure ring on pressing plate are joined brill, reusable.
In sum, the present invention has improved the assembly performance of bearing, have registration, simple to operate, pressure steadily, soft, be beneficial to the features such as installation and removal, die manufacturing cost is cheap, the cycle is short.Greatly alleviate labor intensity, improved manufacturing efficiency, shortened the manufacturing cycle of product, ensured the machining accuracy of bearing, extended the working life of bearing.
