Abstract
The utility model discloses a non-wear boring sleeve which is formed by mixing cast iron and steel, and has the internal structure that is divided into three layers: an outer sleeve, a middle layer and an inner sleeve, wherein an end cover is arranged between the outer sleeve and the outer side of the inner sleeve; the two ends of the middle layer are respectively provided with a bearing which is a rolling bearing; and the inner side of the inner sleeve is provided with at least one through long flat key, and the inner sleeve is made of the cast iron. The non-wear boring sleeve has the advantages of simple structure, low price and permanent service life.
Description
Technical field:
The utility model relates to a kind of anchor clamps that are applicable to the on-the-spot processing of large-scale component, particularly a kind of wear-free boring sleeve.
Background technology:
At present, standard machinery process equipment product processed is subjected to shape, size, restrictions such as weight, the institute of lathe decision just product processed, and the processing of large-scale steel structure is just in time opposite, the processing part is subjected to the restriction of product, can only select the equipment that matches, the equipment that on-the-spot Boring machine comes to this, it is the special equipment of reequiping for the hole of machining large steel construction, it is maximum that this equipment is used is exactly to install a common unit head on the common slide unit additional, but light has such equipment not enough, also needs to mix anchor clamps and cutter and could process and reach all exigent hole of shape and position, boring bar, bushing, universal joint all belongs to anchor clamps, wherein bushing is a consumable accessory, and material is generally cast iron or copper, and price more expensive and service life only is tens hours, not only reduce operating efficiency, also wasted a lot of resources.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, and it is permanent wear-free boring sleeve that a kind of simple in structure, low price, service life are provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of wear-free boring sleeve, it is closed by cast iron and steel reinforced concrete and makes, internal structure is divided into three layers, its three-decker is respectively overcoat, intermediate layer and interior cover, be provided with end cap between the outside of overcoat and interior cover, the two ends in intermediate layer are respectively equipped with bearing, and this bearing is a rolling bearing, the inboard of interior cover is provided with at least one elongated flat key, and the material of interior cover is a cast iron.
The utility model compared with prior art has following having a few:
It only is made up of three-decker, and is simple in structure; It is closed by cast iron and steel reinforced concrete and makes, and has reduced cost, low price; It has improved the integral rigidity of process, has eliminated vibration, and adds and once adjust to the right place man-hour, need not the thick fine finishining of branch, and effect is fine.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of overcoat;
Fig. 3 is the structural representation of interior cover;
Fig. 4 is the structural representation of interior cover;
Number in the figure: cover, 4-end cap, 5-flat key, 6-bearing in 1-overcoat, 2-intermediate layer, the 3-.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of embodiment of the utility model wear-free boring sleeve as Fig. 1, wear-free boring sleeve is divided into three-decker, wear-free boring sleeve is closed by cast iron and steel reinforced concrete and makes, reduced cost, low price, three-decker is respectively overcoat 1, intermediate layer 2 and interior cover 3, structure is very simple, is provided with end cap 4 between the outside of overcoat 1 and interior cover 3, and the two ends in intermediate layer 3 are respectively equipped with bearing 6, this bearing 6 is a rolling bearing, be used for replacing the rolling of boring bar, the inboard of interior cover 3 is provided with at least one elongated flat key 5, slots on boring bar, flat key 5 just is stuck in the relative motion that stops boring bar and bushing in the groove, and the material of interior cover 3 is a cast iron.
Process a hole, cutter must be realized rotating and sliding two and move simultaneously, cutter is fixed on the boring bar, so as long as boring bar is realized rotating and slip is just passable.Drive unit head by slide unit, drive Hooks coupling universal coupling, drive the slip of boring bar at last; Drive the rotation that Hooks coupling universal coupling drives boring bar by unit head; Wherein Hooks coupling universal coupling is the straight line deviation of correction dynamic head main spindle line and institute's machining hole.A boring bar passes two bushings, and bushing is fixed in the support set by three adjustable bolts, and support set is welded on institute's converted products and maintains static, and by the concentricity of adjustable bolt adjusting boring bar and institute's machining hole, thereby realizes the fine finishining in hole.Wear-free boring sleeve is exactly that the rolling of boring bar is separated with sliding, and the dress rolling bearing replaces the rolling of boring bar in the bushing, and the slip of boring bar is very slow, can think not have the wearing and tearing slip.Wear-free boring sleeve has improved the integral rigidity of process, has eliminated vibration, compares with common bushing and raises the efficiency more than 2 times, can process the hole of diameter below 0.94 meter.
