Abstract
The utility model relates to a tool for grinding an eccentric cylindrical roller bearing inner hole. The tool for grinding the eccentric cylindrical roller bearing inner hole is characterized by comprising an eccentric sleeve. An eccentric inner hole is arranged in a right end surface of the eccentric sleeve, a positioning hole communicated with the end portion of the eccentric inner hole is arranged in a left end surface of the eccentric sleeve, a threaded hole communicated with a side wall of the eccentric inner hole is arranged in a circumference of the eccentric sleeve, and inner threads of the threaded hole are connected with a locking screw. An outer circle of the eccentric sleeve and eccentric distance of the eccentric inner hole are equal to eccentric distance of a bearing eccentric inner ring, the bearing eccentric inner ring is placed in the eccentric sleeve before being processed, a location hole of the eccentric sleeve is concentric with a location hole of the bearing eccentric inner ring after rotation, the locking screw locks the bearing eccentric inner ring from a side wall of the eccentric sleeve after utilization of location of a cylindrical pin, then the cylindrical pin is drawn out and the eccentric sleeve can be placed on an electromagnetism clamping device to be ground processed. The tool for grinding the eccentric cylindrical roller bearing inner hole has the advantages of being simple in structure and high in practicability, and reducing cost of production. Meanwhile, by means of the tool for grinding the eccentric cylindrical roller bearing inner hole, the electromagnetism clamping device does not need to be changed.
Description
Technical field
The utility model relates to a kind of bearing processing tool, hole tool in particularly a kind of grinding eccentric cylinder roller bearing.
Background technology
What traditional bearing enterprise all adopted at the grinding bearing internal diameter is not to be in the mood for magnetic holding device, and adopting external diameter and end face is the grinding positioning reference plane, and the concentric bearing of external diameter is processed in accomplishing.Eccentric cylinder roller bearing processing that once in a while can some small lot in the actual production; Model is more single, because company's internal grinder all adopts is not to be in the mood for magnetic holding device, when processing eccentric cylinder roller bearing endoporus; Because bearing inner race cylindrical and endoporus are eccentric, need through eccentric frock clamping.The direct internal diameter of the eccentric roller bearing of grinding is had the inclination anchor clamps for this class bearing than small batch changes one specially, and then manufacturing cost is higher, and working (machining) efficiency is low.
Summary of the invention
The technical problem that the utility model will solve provide a kind of can be directly in the frock of not being in the mood for grinding eccentric cylinder roller bearing endoporus on the magnetic holding device.
For solving the problems of the technologies described above; The technical scheme of the utility model is: hole tool in a kind of grinding eccentric cylinder roller bearing; Its innovative point is: comprise an eccentric bushing, said eccentric bushing its right end face has eccentric inner hole, and the left end face of said eccentric bushing has the locating hole that is communicated with the eccentric inner hole end; Be drilled with the screwed hole that is communicated with the eccentric inner hole sidewall on the periphery of said eccentric bushing, said screwed hole internal thread connects lock-screw.
The advantage of the utility model is: the cylindrical of eccentric bushing and the eccentric throw of eccentric inner hole equal the eccentric throw of the eccentric inner ring of bearing, before the processing, the eccentric inner ring of bearing are put into eccentric bushing; Make after the rotation that the locating hole of the eccentric inner ring of locating hole and bearing of eccentric bushing is concentric, utilize the straight pin location after, again by lock-screw behind the eccentric inner ring of eccentric bushing sidewall locking bearing; Extract straight pin out; Can eccentric bushing be placed on and carry out grinding on the magnetic holding device, simple in structure, practicality is high; Need not to change magnetic holding device, reduce production costs.
Description of drawings
Fig. 1 is the utility model grinding eccentric cylinder roller bearing endoporus tool structure sketch map.
The specific embodiment
As shown in Figure 1, comprise eccentric bushing 1, locating hole 2, lock-screw 3.
Above-mentioned eccentric bushing 1 its right end face has eccentric inner hole, and the cylindrical of eccentric bushing 1 and the eccentric throw of eccentric inner hole need to equal the eccentric inner ring eccentric throw of bearing of processing.
The left end face of eccentric bushing 1 has the locating hole 2 that is communicated with the eccentric inner hole end, is drilled with the screwed hole that is communicated with the eccentric inner hole sidewall on the periphery of eccentric bushing 1, and connects lock-screw 3 at the screwed hole internal thread.
Before the processing; The eccentric inner ring 4 of bearing is put into eccentric bushing 1; Make after the rotation that the locating hole of the eccentric inner ring 4 of locating hole 2 and bearing of eccentric bushing 1 is concentric, utilize the straight pin location after, again by lock-screw 3 behind the eccentric inner ring 4 of eccentric bushing 1 sidewall locking bearing; Extract straight pin out, can eccentric bushing be placed on and carry out grinding on the magnetic holding device.
