Description
Technical field
The utility model relates to clamp art, is specifically related to a kind of bearing insert fixture.
Background technology
Bearing insert, be a kind of cylindric, inside is hollow structure, and be mainly used in being connected with bearing, concrete realizes being connected by the mode of small―gap suture or interference fits with the external cylindrical surface of bearing for the hollow inwall of bearing insert; Thus its wearing and tearing less in bearing rotation process.But, the hollow processing method of current this its inside of bearing insert, generally first mill out coarse inwall, then the lateral wall of scroll chuck clamping bearing insert is adopted, then it is driven to rotate in a circumferential direction, and the inner side that milling cutter enters into bearing insert under the driving of drive unit is cut accurately, to reaching inner wall smooth, and the product can fitted completely with the outside cylinder of bearing; But above-mentioned this processing method, there is certain deficiency, first, if bearing insert wall thickness is thinner, as the bearing insert of 2-4mm thickness, to run up the phenomenon that the process that rubs can cause its temperature to raise with milling cutter, but the claw having a scroll chuck directly and bearing insert clamped contact, cause bearing insert to be easy to distortion under high temperature, thus the cylindrical outer wall being difficult to realization and bearing is fitted; And above-mentioned this processing mode also can cause bearing insert stress surface few, and particularly axial two ends do not have fixed structure, are easy to make it be out of shape.
Utility model content
The utility model, for the above-mentioned deficiency of prior art, provides a kind of stress surface many, on-deformable bearing insert fixture.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of bearing insert fixture, comprise scroll chuck, scroll chuck is axially provided with chuck body, described chuck body comprises and to obtain the fixing axle of claw with scroll chuck, the front end of axle is provided with the draw-in groove of accommodating bearing insert, and described draw-in groove is that cylindrical and its madial wall and bearing insert lateral wall fits, and is provided with the annulus leant with bearing insert end bottom draw-in groove; The lateral wall of described draw-in groove is provided with external screw thread, the lateral wall of the described draw-in groove inwall that is threaded arranges the friction top of internal thread, the end of described friction top is circular, and after friction top is threaded with draw-in groove, the both ends of the surface of bearing insert lean on the inner surface of draw-in groove annulus and the contacted inner surfaces of friction top respectively.
Adopt said structure, first the claw fixed axis of scroll chuck is adopted, and bearing insert to be processed is positioned in draw-in groove, then friction top is screwed, bearing insert is firmly fixed in draw-in groove, now the lateral wall of bearing insert and both ends of the surface are all pushed against fixing, and the hollow position that then milling cutter extends axially through the cylindric end of friction top enters into bearing insert inside and carries out milling.This fixture effectively ensure that bearing insert many-side is stressed, thus reduces the thermal deformation of its process, and the Product Precision of acquisition is higher, and realizes between bearing well coordinating, and can not be out of shape, can not be eccentric, effectively ensure that the success rate of processing.
As preferably, described axle central shaft, to being provided with the through hole entered for cooling medium, adopting this structure, constantly passes into cooling medium in milling tool process in through hole, thus fully lower the temperature to milling position, reduces the thermal deformation of bearing insert further.
As preferably, described friction top radial symmetric is provided with two holding rods, and described holding rod is threaded with friction top by the radial direction through hole of friction top.Adopt this structure, when rotating friction top, two holding rods hold with a firm grip with regard to easy manipulation, and this structure when friction top and draw-in groove are connected and fixed put in place after, holding rod radial direction is screwed to friction top, holding rod be positioned at friction top one end can with the external screw thread of draw-in groove against, in the process of draw-in groove and friction top High Rotation Speed, can not running, retrodict, remain the pressuring action to bearing insert.

Detailed description of the invention
Below by embodiment, the present invention is described in further detail, but the present invention is not only confined to following examples.
As shown in drawings, a kind of bearing insert fixture of the present utility model, comprise scroll chuck 1, scroll chuck 1 is axially provided with chuck body, described chuck body comprises the axle 2 fixing with the claw 1.1 of scroll chuck, the front end of axle is provided with the draw-in groove 3 of accommodating bearing insert, and described draw-in groove 3 is that cylindrical and its madial wall and bearing insert lateral wall fits, and is provided with the annulus 3.1 leant with bearing insert end bottom draw-in groove; The lateral wall of described draw-in groove is provided with external screw thread 3.2, the lateral wall of the described draw-in groove inwall that is threaded arranges the friction top 4 of internal thread, the end 4.1 of described friction top 4 is in circular, and after friction top is threaded with draw-in groove, the both ends of the surface of bearing insert lean on the inner surface of draw-in groove annulus and the contacted inner surfaces of friction top respectively.It is equal with the wall thickness of bearing insert with its radial distance of end 4.1 in circular friction top that this tests above-mentioned annulus 3.1.
Adopt said structure, first the claw fixed axis of scroll chuck is adopted, and bearing insert to be processed is positioned in draw-in groove, then friction top is screwed, bearing insert is firmly fixed in draw-in groove, now the lateral wall of bearing insert and both ends of the surface are all pushed against fixing, and the hollow position that then milling cutter extends axially through the cylindric end of friction top enters into bearing insert inside and carries out milling.This fixture effectively ensure that bearing insert many-side is stressed, thus reduces the thermal deformation of its process, and the Product Precision of acquisition is higher, and realizes between bearing well coordinating, and can not be out of shape, can not be eccentric, effectively ensure that the success rate of processing.
The central shaft of axle 2 described in the utility model is to being provided with the through hole 2.1 entered for cooling medium, adopt this structure, in through hole, constantly pass into cooling medium in milling tool process, thus milling position is fully lowered the temperature, reduce the thermal deformation of bearing insert further.
Friction top radial symmetric described in the utility model is provided with two holding rods 4.2, and described holding rod is threaded with friction top by the radial direction through hole of friction top.Adopt this structure, when rotating friction top, two holding rods hold with a firm grip with regard to easy manipulation, and this structure when friction top and draw-in groove are connected and fixed put in place after, holding rod radial direction is screwed to friction top, holding rod be positioned at friction top one end can with the external screw thread of draw-in groove against, in the process of draw-in groove and friction top High Rotation Speed, can not running, retrodict, remain the pressuring action to bearing insert.
