Abstract
The utility model discloses an automobile hub processing and positioning device which comprises a cylindrical sleeve body; the cavity of the sleeve body is formed by a cylindrically direct cavity section and a cone-frustum shaped cone cavity section which are communicated with each other; the sleeve body is fixedly connected with a flange plate which is arranged near to the outer end of the direct cavity section; the sleeve body is provided with a plurality of openings at interval which pass through the cavity of the sleeve body and the length direction of the openings are consistent with the axial direction of the sleeve body; the starting point of each opening begins from the outer end of the cone cavity section and the finishing point thereof ends with the inner end of the direct cavity section; the sleeve body is internally provided with an expansion core which can axially slide and can not rotate; the shape of the end part of the expansion core, which is near to the core cavity section, corresponds to the shape of the cone cavity section; the expansion core is fixedly connected with a stud bolt by which the cone cavity section is exposed from the end of the cone cavity section; the stud bolt is screwed with the nut; and a pressure plate which is sheathed on the stub bolt is arranged between the nut and the sleeve body. The positioning device has the advantages of simple structure and convenient use and can bring about good axiality for two bearings rooms of the automobile hub.
Description
Technical field
The utility model relates to the positioner of turning automobile hub bearing chamber.
Background technology
At present, adopt the bearing chamber at horizontal lathe or vertical lathe processing automobile wheel hub two ends usually, horizontal lathe is with respect to vertical lathe, and equipment investment is less and be widely adopted.Wheel hub use horizontal lathe add man-hour frock and wheel hub have the gap, because gravity effect, make the hub bearing chamber near the frock upper surface, after compressing processing, there is mismachining tolerance in the hub bearing chamber, also there is this situation during processing another side bearing chamber, behind the deviation accumulation, causes two bearings chamber axiality not reach requirement.
Summary of the invention
The technical problems to be solved in the utility model is at above-mentioned defective, and a kind of processing and positioning device that can guarantee automotive hub two bearings chamber axiality is provided.
For solving the problems of the technologies described above, the utility model provides a kind of automotive hub processing and positioning device of following structure, its design feature is to comprise columned body, the inner chamber of body is made of cylindrical straight chamber section that is interconnected and the awl chamber section that is circular cone shape, be connected with the ring flange that is provided with near straight section outer end, chamber on the body, spaced apart many axial consistent openings that connect cover intracoelomic cavity and length direction and body that are provided with on the body, the starting point of each opening starts from the inner that outer end, the terminal point of boring the chamber section terminate in straight chamber section; The bloated core that can endwisely slip and can not rotate is housed in the body, the core that expands is corresponding with awl chamber section near the shape of awl chamber Duan Duan, be connected with the double-screw bolt that exposes body from awl chamber Duan Duan on the bloated core, be bolted with nut on the double-screw bolt, be provided with the platen that is sleeved on the double-screw bolt between nut and the body.
The outer peripheral face of described bloated core is provided with the axial consistent spline plane of length direction and body, is connected with the limited block that cooperates with the spline plane on the body.
After the bearing chamber completion of processing of automotive hub one end, this bearing chamber is sleeved on an end of the awl chamber section of the body that is installed on the horizontal lathe, rotating nut makes platen compress automotive hub, platen compresses in the process of automotive hub, core close gradually platen under the pulling of double-screw bolt expands, because spaced apart being provided with indulged many openings of striding whole cone cavity section on the body, the core that expands will be bored the chamber section in moving process multistage chamber wall struts synchronously, the locular wall of chamber wall and bearing chamber is tightly fitted, thereby realize that body cooperates with the no gap of automotive hub, and under the effect of synchronous tension force, overcome the gravity of wheel hub self, body center and wheel hub center align automatically, finally reach the purpose of centering wheel hub center.When utilizing the bearing chamber of the utility model processing automobile wheel hub other end, can guarantee the axiality of two bearings chamber.
In sum, the utlity model has advantage simple in structure, easy to use, use can bring the good beneficial effect of automotive hub two bearings chamber axiality.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is the structural representation of the utility model user mode;
Fig. 2 is the cutaway view along A-A line among Fig. 1;
Fig. 3 is the cutaway view along B-B line among Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2 and automotive hub processing and positioning device shown in Figure 3, comprise columned body 1, the inner chamber of body 1 is made of cylindrical straight chamber section 11 that is interconnected and the awl chamber section 12 that is circular cone shape, be connected with the ring flange 2 that is provided with near straight section outer end, chamber on the body 1, ring flange 2 is provided with and is used for the bolt hole 13 that is connected with the lathe spindle flange, spaced apart axial consistent many openings 10 that connect cover intracoelomic cavity and length direction and body that are provided with on the body 1, the starting point of each opening starts from the outer end of awl chamber section, terminal point terminates in the inner of straight chamber section, the chamber wall that many openings will be bored chamber section 12 is divided into many, the number of opening struts with easy chamber wall with many awl chamber sections and exceeds, and four openings 10 have been shown among Fig. 2.The bloated core 3 that can endwisely slip and can not rotate is housed in the body 1, and bloated core 3 is corresponding with awl chamber section 12 near the shape of awl chamber Duan Duan, and corresponding target is that bloated core 3 can strut the chamber walls of many awl chamber sections in moving process; The implementation that can endwisely slip and can not rotate of bloated core 3 is as follows: the outer peripheral face of the core 3 that expands is provided with spline plane 7 longitudinally, be length direction and body axial consistent on spline plane 7, be connected with the limited block 8 that cooperates with spline plane 7 on the body 1, this limited block 8 is fitted with spline plane 7, limited block 8 does not limit moving axially of the core 3 that expands, and but can stop the rotation of the core 3 that expands.Be connected with the double-screw bolt 4 that exposes body 1 awl chamber Duan Duan on the bloated core 3, be bolted with nut 5 on the double-screw bolt 4, be provided with the platen 6 that is sleeved on the double-screw bolt 4 between nut 5 and the body 1.With reference to Fig. 1, the effect of platen 6 is axial lockings of realizing automotive hub 9 and body 1, many chamber walls of body 1 awl chamber section 12 are strutted and tightly fits with the locular wall of the bearing chamber of automotive hub 9 with the core 3 of realizing expanding.
