Abstract
The utility model relates to a bearing for abrasive-machining a large bearing collar. The bearing comprises a floating bearing and a bearing base, and is characterized by further comprising a first positioning block, a second positioning block, a limiting plate and a fine-turning bolt, wherein the floating bearing and the bearing base are movably connected by a pin; the first positioning block and the second positioning block are fixed on a frame on the two sides of the bearing base; a gap is provided among the bearing base, the first positioning block and the second positioning block; the limiting plate is fixedly connected with the first positioning block and the second positioning block; one end of the fine-turning bolt is limited on the limiting plate; and the other end of the fine-turning bolt is connected with the bearing base in a threaded manner. Nicks are arranged on the two ends of the floating bearing provided in the utility model, so as to conveniently install small bearings. A circular-arc slot which is matched with the fine-turning bolt is arranged on the limiting plate provided in the utility model. The bearing has the advantages that the eccentricity of a bearing position can be regulated and ensured more accurately through the fine-turning bolt; and the bearing base can be prevented from axial deflection through the two positioning blocks.
Description
Technical field
The utility model relates to a kind of supporting that is used for the processing of large size bearing (more than the bearing outside diameter 400mm) lasso mill.
Background technology
Floating support is a kind of grinding bearing rings that is applied in, and is used for supporting and bears lasso at mill process grinding force, and the floating support that adopts is at present connect through pin by floating support 1 ' and rear branching holder 2 '.Referring to Fig. 1, this product is simple in structure because of it, the following shortcoming of existence:
1. though adopt this directly simple in structure through the pin connection at present by floating support 1 and rear branching holder 2; But in use owing to will adjust offset; Can only firmly knock rear branching holder adjustment offset, because firmly inhomogeneous, offset is difficult to adjust to suitable position;
2. because rear branching holder 2 is fixed on the lathe through screw, because stressed bigger, it is loosening to cause screw to have in the grinding process, rear branching holder 2 produces with lathe and slides, thereby causes eccentric quantitative change big, and then causes grinding to produce chatter mark and burn.
Present structure can not solve the problem of burn and precision raising well.
The utility model content
The utility model technical problem to be solved is to overcome existing above-mentioned deficiency in the prior art, and provide a kind of simple in structure, easy for installation, can more accurately adjust and when guaranteeing work bearing position offset and supporting base the axially crooked supporting that is used for the processing of large-scale bearing ring mill can not take place.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of supporting that is used for the processing of large-scale bearing ring mill; Comprise floating support, supporting base; It is characterized in that also being provided with first locating piece, second locating piece, limiting plate, trimming bolt, floating support and supporting base are through the pin link joint, and first locating piece and second locating piece are fixed on the frame of supporting base both sides; Gapped between the supporting base and first locating piece, second locating piece; Limiting plate is fixedly connected with first locating piece, second locating piece, and trimming bolt one end is spacing on limiting plate, and the trimming bolt other end and supporting base pass through thread connection.
The two ends of the utility model floating support are provided with breach, are convenient to install little bearing.
The utility model limiting plate is provided with arc groove, and trimming bolt cooperates with arc groove.
The utility model floating support, supporting base, first locating piece, second locating piece, limiting plate, trimming bolt and some pin materials all can adopt steel No. 45, and trimming bolt adopts modifier treatment.
The utlity model has following advantage and effect: can more accurately adjust and the offset of bearing position when guaranteeing work through trimming bolt, can guarantee that through two locating pieces axial crooked phenomenon can not take place supporting base.

The specific embodiment
Referring to Fig. 2~Figure 10, the utility model embodiment comprises that floating support 1, supporting base 2, the first locating piece 3-1, the second locating piece 3-2, limiting plate 4, trimming bolt 5 and some pins make.The two ends of floating support 1 are provided with breach 11 (see figure 3)s; Can little bearing be installed through pin; Floating support 1 passes through the pin link joint with supporting base 2; Floating support 1 can be pinned to floating at the center; All having two locating piece through holes, 31, the first locating piece 3-1 and the second locating piece 3-2 on the first locating piece 3-1 and the second locating piece 3-2 can be fixed on the frame of supporting base 2 both sides through two locating piece through holes 31 and screw, gapped between the supporting base 2 and the first locating piece 3-1, the second locating piece 3-2; Be convenient to supporting base 2 can be between two locating pieces radially (above-below direction among Fig. 2) slide, and it is crooked to guarantee can not take place axially (left and right directions among Fig. 2); Limiting plate 4 two ends are provided with limiting plate through hole 41; Be convenient to be fixed on the locating piece (comprising the first locating piece 3-1, the second locating piece 3-2) through locating piece screwed hole 32 connections of bolt and the first locating piece 3-1 and the second locating piece 3-2 end; Thereby be integral with frame, can be moved, in the spacing arc groove 42 on limiting plate 4 of trimming bolt 5 one ends; The supporting base screwed hole 21 of the other end and supporting base 2 ends passes through spiral marking connection; Because trimming bolt 5 one ends are positioned on the limiting plate 4 and can not move, can supporting base 2 radially be slided through regulating trimming bolt 5.Adjustment workpiece offset is through regulating trimming bolt 5, radially sliding in the both sides of locating piece 3 thereby drive supporting base 2, owing to be to adopt bolt to regulate; Amount of feeding precision is higher, satisfy the requirement to the accuracy of offset, and supporting base 2 can not produce in sliding process crooked; Thereby guaranteed the contact area of floating support 1 and workpiece, in grinding process, supporting base 2 is also through being bolted on the frame; Because workpiece is stressed bigger in grinding process, thereby very easily makes the bolt looseness of supporting base 2 cause supporting base 2 to slide; Adopt limiting plate 4 can limit the slip of supporting base 2, thereby guaranteed offset.
The design feature of the utility model embodiment; Make bearing life and precision improve greatly; Can more accurately adjust and the offset of bearing position when guaranteeing work through micromatic setting, can guarantee that through two locating pieces axial crooked phenomenon can not take place supporting base 2.
