Abstract

The utility model relates to a ferrule assembling mold for a cylindrical roller bearing, which consists of a wedge, a locking collar blank pressing mold and a cushion block, wherein the blank pressing mold is uniformly cut into four equal portions by a line cutting method; the cutting gap is 4 mm; the conical surface of the wedge is 60 degrees; the locking collar blank pressing mold is arranged on the cushion block; the wedge is arranged in the locking collar blank pressing mold; and the wedge expands four equal portions of the locking collar blank pressing mold through pressing, so a connecting element bearing locking collar between a first inner ring of the bearing and a second inner ring of the bearing is bent to connecting slots of the first inner ring of the bearing and the second inner ring of the bearing through being pressed, and the two inner rings are combined into a whole body. The utility model has the advantages of simple structure, convenient use and stable operation. Finished products meet the technical requirements.

Description

Roller bearing lasso assembling mould

Technical field

The utility model belongs to technical field of bearings, relates to a kind of roller bearing lasso assembling mould, is applicable to the roller bearing of two inner rings.

Background technique

The trial-production first of the utility model system, and carry out optimizing design scheme, owing to do not have this type assembling scheme in the past, therefore, need the tracking test process, accumulate experience, for the processing and the assembling of processing bearing of the same type from now on lays the foundation.

Summary of the invention

The purpose of this utility model provides a kind of roller bearing lasso assembling mould.Can be bound up by the inner ring of retainer, and can guarantee the stable rotation of bearing inner race two separation.

Technical solution of the present utility model is: a kind of roller bearing lasso assembling mould, by chock 1, retainer flanging mould 2 and cushion block 7 are formed, the method of flanging mould 2 usefulness lines cutting cuts into uniform quarter, cutting gap is 4mm-5mm, chock 1 conical surface is 60 °, retainer flanging mould 2 is placed on the cushion block 7, chock 1 is placed in the flanging mould 2, the conical surface even contact of the conical surface of chock 1 and retainer flanging mould 2, chock 1 is pressed the retainer flanging mould 2 of quarter and is risen, bearing first inner ring 3 and the connection piece bearing locking collar 4 of axle between second inner ring 6 are bent in the set connection groove of bearing first inner ring 3 and axle second inner ring 6, make bearing first inner ring 3 and bearing second inner ring 6 become one.

The beneficial effects of the utility model are, retainer flanging mould cuts into uniform quarter with the method for line cutting, the chock that with the conical surface is 60 ° rises by the retainer flanging mold pressing of quarter, thereby retainer is bent in the connection groove of two inner rings, is coupled as one to reach two inner rings.The utility model is simple in structure, and is easy to use, and it is stable to work, and finished product meets technical requirements.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Among the figure 1, chock, 2, retainer flanging mould, 3, bearing first inner ring, 4, bearing locking collar, 5, bearing outer ring, 6, bearing second inner ring, 7, cushion block.

Embodiment

As shown in Figure 1, the utility model is by chock 1, retainer flanging mould 2 and cushion block 7 are formed, the method of retainer flanging mould 2 usefulness lines cutting cuts into uniform quarter, cutting gap is 4mm, chock 1 conical surface is 60 °, retainer flanging mould 2 is placed on the cushion block 7, chock 1 is placed in the retainer flanging mould 2, chock 1 is pressed the retainer flanging mould 2 of quarter and is risen, bearing first inner ring 3 and the connection piece bearing locking collar 4 of axle between second inner ring 6 are bent in the set connection groove of bearing first inner ring 3 and axle second inner ring 6, make bearing first inner ring 3 and bearing second inner ring 6 become one.Guarantee that chock 1 and conical surface angle in the retainer flanging mould 2 will keep even contact, move to direction radially to guarantee when being subjected to tension retainer flanging mould 2 each detached body.During assembling, at first will be by bearing locking collar 4, bearing outer ring 5, the bearing unit that bearing first inner ring 3 and axle second inner ring 6 are formed is placed on the cushion block 7, again with retainer flanging mould 2, chock 1 is placed on the working position shown in Figure 1 successively lightly, make the conical surface even contact of the conical surface and the retainer flanging mould 2 of chock 1, under the effect of press machine external force, chock 1 evenly moves down along the contact conical surface, the detached body of equally distributed retainer flanging mould 2 of while, under the effect of chock 1, radially move, the retainer edge can be bent, thereby the two bearings inner ring is coupled as one.

Claims
