Abstract
A mold for processing a lock orifice of a copper retainer for a cylinder roller bearing relates to the technical field of processing lock orifices of copper retainers for bearings and comprises an external diameter clamping surface and an internal diameter locating surface; and a trisected slot is arranged on the periphery of the mold. The trisected slot is three slots that are not mutually communicated, and the internal diameter of the mold is the same as the external diameter of the processed retainer. The mold is characterized in that when the rolling lock orifice of the copper retainer for a cylindrical roller is processed, a tool rest of an engine lathe is connected with a roller wheel; the external diameter clamping surface of the mold is clamped on a main shaft of the lathe; the retainer is sheathed on the internal diameter locating surface of the mold; the main shaft performing high-speed rotation drives the mold and the retainer to move; and after being in contact with the retainer, the roller wheel rotates driven by the rotating retainer and extrudes and rolls the internal diameter surface of the retainer simultaneously so as to lead the retainer to roll out a mark with the same width as that of the roller wheel, namely the lock orifice of the retainer.
Description
Technical field
The utility model relates to bearing copper cage fore shaft processing technique field, is the mold that is used for processing column roller bearing copper cage fore shaft concretely.
Background technology
Retainer plays separation roller in bearing, keep rolling element, the effect of guiding rolling element.It is allow rolling element enter in the pocket hole of retainer that retainer keeps rolling element, but also must not drop out from the pocket hole of retainer.In order to realize this function of retainer, when the processing retainer, must the processing fore shaft.The processing of retainer fore shaft is a difficult problem always, and particularly the processing of the retainer of interior fore shaft is more difficult.The fore shaft amount is excessive, and roller enters less than going in the retainer pocket hole, and the fore shaft amount is little, just produces the roller problem, so the processing of retainer fore shaft is an important techniques research and development problem always.Traditional processing mode adopts the processing of punching press fore shaft, tends in the process of punching press, makes retainer produce distortion, and in addition, the size of stamping press directly influences the uniformity of size, and the quality of evenly locking roller does not reach standard-required.And efficient is very low, and is not only time-consuming but also require great effort.
Summary of the invention
Defective in view of the prior art existence, the purpose of this utility model provides a kind of mold that is used for processing column roller bearing copper cage fore shaft, make the technological operation of processing column roller copper cage rolling fore shaft simple after using this mold, and can on engine lathe, process fore shaft in the retainer, well guarantee the retainer dimensional uniformity after the processing, and improved production efficiency greatly.
For achieving the above object, the technical scheme that the utility model adopted is: be used for the mold of processing column roller bearing copper cage fore shaft, comprise external diameter clamping area and internal diameter locating surface, the circumference of mold is provided with the groove of trisection.
The groove of described trisection is three obstructed grooves.
The size of the internal diameter of described mold is identical with the external diameter of the retainer of being processed.
Of the present utility model being characterised in that when processing column roller bearing copper cage rolling fore shaft, on the knife rest of engine lathe, connect roller, the external diameter clamping area clamping of mold is on the main shaft of lathe, retainer is enclosed within on the internal diameter locating surface of mold, when main shaft rotates at a high speed, driving mold moves with retainer, after roller touches retainer, under the retainer of rotation drives, be rotated, and simultaneously the retainer inside diameter surface pushed, roll, make retainer roll out the wide impression of roller, i.e. retainer fore shaft.
The beneficial effects of the utility model are: use this mold in the technology of processing column roller bearing copper cage rolling fore shaft, make processing technology simple to operate, and can on engine lathe, use fore shaft in this mold processing retainer, well guarantee the retainer dimensional uniformity after the processing, and improved production efficiency greatly.
Description of drawings
Fig. 1 is the plan structure schematic diagram that is used for the mold of processing column roller bearing copper cage fore shaft;
Fig. 2 is the left TV structure schematic diagram that is used for the mold of processing column roller bearing copper cage fore shaft.
Among the figure: 1, mold, 1a, external diameter clamping area, 1b, internal diameter locating surface, the groove of 1c, trisection.
The specific embodiment
The mold that is used for processing column roller bearing copper cage fore shaft shown in Fig. 1,2, mold 1 comprise external diameter clamping area 1a and internal diameter locating surface 1b, are provided with the groove 1c of trisection on the circumference of mold 1; The groove 1c of described trisection is three obstructed grooves.Open three obstructed grooves on the circumference, make mold 1 have retractility, guarantee that workpiece is clamped;
The size of the internal diameter of described mold 1 is identical with the external diameter of the retainer of being processed.The internal diameter locating surface 1b of mold 1 is mainly used in the location of retainer, and internal diameter size is consistent with the external diameter of retainer, and both closely cooperate, and guarantees that it does not rotate at internal diameter, makes the fore shaft consistent size after the processing.
Of the present utility model being characterised in that when processing column roller bearing copper cage rolling fore shaft, on the knife rest of engine lathe, connect roller, the external diameter clamping area 1a clamping of mold 1 is on the main shaft of lathe, retainer is enclosed within on the internal diameter locating surface 1b of mold 1, when main shaft rotates at a high speed, drive mold 1 and move with retainer, roller just can be in the extruding of retainer inside diameter surface, the formation fore shaft.External diameter clamping area 1a is used for the clamping of scroll chuck, and main shaft drives it and rotates at a high speed, realizes the processing of fore shaft under the extruding of roller.
