Abstract
The utility model discloses a quick change type movable flat centre which belongs to a machine tool accessory; and the utility model aims to provide a quick change type movable flat centre with high roll lifting efficiency and good grinding precision. The utility model has the technical proposal that the device includes a bearing pedestal, a bearing and a revolving axle; the front end of the revolving axle (3) is provided with a thrust bearing (4), and the middle section and the tail end thereof are respectively equipped with a self-aligning bearing (6), an inner space ring (8) and an outer space ring (7) are disposed between the two self-aligning bearings (6), and the tail end of the revolving axle (3) is provided with a lock nut (10); and the bearing pedestal (5) is mounted on the outer ring of the bearing, a top disk (1) is fixed on the end face of the revolving axle (3), and a blind flange (11) is fixed on the end face of the bearing pedestal (5). The utility model has advantages of simple structure, convenient installation and demounting, high roll lifting and calibration efficiency and good grinding precision, and is applied to a roll grinder which utilizes a central supporter to support the roll grinding.
Description
Technical field:
The utility model relates to a kind of machine tool accessories, relates in particular to a kind of top.
Background technology:
At present, in the grinding process of roll, the overwhelming majority adopts centre frame and back dead centre to come back up roll to carry out grinding.For fear of the centre bore that damages back dead centre and roll, generally will be on pad between top and the roll wood or bakelite, simultaneously since between top and the roll for rigidity contacts, relative motion relation is arranged between the two, moment of friction is bigger; Therefore, lift, proofread and correct more time-consuming, the effort of roll in this case, inefficiency, very inconvenient.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of roll grinder that is applicable to and utilizes the center bearing bracket back up roll, and roll lifting efficient height, the movable flat-top point of quick-changing type that grinding accuracy is good.
To achieve these goals, the utility model by the following technical solutions: it comprises bearing block, bearing and gyroaxis; The front end of gyroaxis is equipped with thrust bearing, stage casing and a tail end self-aligning bearing respectively is installed, and is provided with cone spacer and outer ring spacer between two self-aligning bearings, and the tail end of gyroaxis is equipped with locking nut; Bearing block is installed on the outer ring of above-mentioned bearing, takes over a business to be fixed on the end face of gyroaxis, sends out blue lid and is fixed on the bearing block end face.
Thrust bearing is the bearing with cross roller roller bearing, and self-aligning bearing is a self-aligning ball bearing; Between self-aligning bearing and locking nut, be provided with the adjustment pad.
Compared with the prior art, the utility model has been owing to adopted technique scheme, therefore have simple in structure, installation and removal are convenient, the lifting of roll and proofread and correct advantages such as efficient height, grinding accuracy are good.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: take over a business 1 screw, 2 gyroaxises, 3 thrust bearings, 4 bearing blocks, 5 self-aligning bearings, 6 outer ring spacers, 7 cone spacers 8 and adjust 10 blue lids 11 of pad 9 locking nuts
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Thrust bearing 4 and two self-aligning bearings 6 are installed in front end, stage casing and the tail end of stairstepping gyroaxis 3 respectively, are provided with cone spacer 8 and outer ring spacer 7 between two self-aligning bearings 6, and the tail end of gyroaxis 3 is equipped with the locking nut 10 that self-aligning bearing 6 inner rings are compressed.The outer ring of above-mentioned each bearing is installed on the bearing block 5, sends out blue lid 11 and is fixed on the end face of this bearing block by screw 2 and the outer ring of self-aligning bearing 6 is compressed; Taking over a business 1 is fixed on the front end face of gyroaxis 3 by other screw 2.
In order to improve grinding accuracy, thrust bearing 4 adopts the bearing with cross roller roller bearing, and self-aligning bearing 6 adopts self-aligning ball bearing; For the ease of adjusting, between self-aligning bearing 6 and locking nut 10, be provided with and adjust pad 9; In order to mount and dismount conveniently, bearing block 5 cooperates and the fastening mode of screw with adopting short cone being connected of tailstock.
