Abstract
The utility model relates to a boring sleeve. The boring sleeve comprises an outer sleeve and a nylon inner sleeve which is installed in an inner hole of the outer sleeve by a clamping fixing device, the outer diameter of the nylon inner sleeve is matched with the diameter of the inner hole of the outer sleeve, and an inner hole which is matched with the outer diameter of a boring rod is formed in the nylon inner sleeve in a sleeved mode. Due to the facts that the nylon inner sleeve is fixed in the outer sleeve and nylon materials are abrasion-resisting, the boring rod is inserted into the nylon inner sleeve to rotate so as to be capable of effectively avoiding steel-to-steel matching of the boring sleeve and the boring rod which are made of steel, and the boring rod easy to abrade affecting the service life is effectively prevented. Meanwhile, the nylon inner sleeve is detachably installed in the outer sleeve by the clamping fixing device, therefore, when the nylon inner sleeve is abraded, a novel nylon sleeve can be convenient to dismantle and replace, and is used again, and use cost of the boring sleeve is reduced.
Description
Technical field
The utility model relates to a kind of machined frock, is specifically related to a kind of bushing.
Background technology
As everyone knows, boring machine adds that man-hour often to occur portioned product far away because of machining hole distance, therefore need to increase and lengthen boring cutter bar, lengthening boring cutter bar needs to fix with bushing, cooperate for steel to steel between bushing commonly used and the boring bar, easy to wear and the wearing and tearing backs bushing of bushing and boring bar can't be repaired, and can only scrap, and boring bar is reduction of service life also.
Summary of the invention
The utility model provides a kind of interior cover removable bushing in order to overcome the deficiency of above technology.
The technical scheme that its technical problem that overcomes the utility model adopts is:
This bushing comprises overcoat, is installed in the nylon in the overcoat endoporus by clamping device and overlaps, and the external diameter of cover is complementary with the diameter of bore of overcoat in the described nylon, overlaps in the described nylon to be provided with the endoporus that is complementary with the boring bar external diameter.
Above-mentioned clamping device comprises the gland that is fixed in the overcoat outer face by screw, and the outer face of cover is concordant with the overcoat outer face in the described nylon.
The beneficial effects of the utility model are: because cover in the nylon fixedly is arranged in the overcoat, nylon material is wear-resisting, so boring bar is inserted into to rotate in the cover in the nylon and can effectively avoids the steel bushing to cooperate with the steel to steel of boring bar, and preventing effectively that boring bar is easy to wear influences its life-span.And cover detachably is installed in the overcoat by clamping device in the nylon, therefore after cover wearing and tearing nylon in, can be for convenience detach and the nylon that more renews in cover continuation use, reduced the use cost of this bushing.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure, 1. overlap 3. glands, 4. screws in overcoat 2. nylon.
The specific embodiment
Be described further below in conjunction with 1 pair of the utility model of accompanying drawing.
This bushing comprises overcoat 1, is installed in the nylon in overcoat 1 endoporus by clamping device and overlaps 2, and the external diameter of cover 2 is complementary with the diameter of bore of overcoat 1 in the described nylon, overlaps 2 in the described nylon and is provided with the endoporus that is complementary with the boring bar external diameter.Because cover 2 in the nylon fixedly is arranged in the overcoat 1, and nylon material is wear-resisting, so boring bar is inserted into to rotate in the cover 2 in the nylon and can effectively avoids the steel bushing to cooperate with the steel to steel of boring bar, and preventing effectively that boring bar is easy to wear influences its life-span.And cover 2 detachably is installed in the overcoat 1 by clamping device in the nylon, therefore after 2 wearing and tearing of cover nylon in, can be for convenience detach and the nylon that more renews in cover continuation use, reduced the use cost of this bushing.
Above-mentioned clamping device comprises the gland 3 that is fixed in overcoat 1 outer face by screw 4, and the outer face of cover 2 is concordant with overcoat 1 outer face in the described nylon.After cover 2 is inserted in the endoporus of overcoat 1 in nylon, end cap is placed on the outer face of cover 2 in overcoat 1 and the nylon, screwing screw 4 afterwards can be fixing with cover in the nylon 2.Installing/dismounting is simple, and is fixing reliable.
