Technical Field
[0001] The utility model relates to the technical field of gears, in particular to a positioning device for drilling and boring the outer circle of a gear ring. Background Art
[0002] When processing planetary gears, holes need to be drilled on the outer side wall of their outer circles. Existing fixtures often cannot hold firmly during processing. At the same time, when multiple holes need to be drilled with existing fixtures, continuous adjustment is required, and their accuracy is often poor. Moreover, this processing method has a slow processing efficiency. Summary of the Invention

A buckle is arranged on the base. A column is vertically and fixedly installed on the base. A bearing seat is arranged on the column. A fixed disk is installed on the bearing seat. A threaded rod is fixedly arranged at the center of the fixed disk. A nut is arranged on the threaded rod. A through hole is arranged on the fixed disk. A bolt is arranged at the bottom of the column. A steel ball is arranged at one end of the bolt close to the fixed disk. A groove for accommodating the steel ball is arranged on one side of the fixed disk close to the column.
[0004] In order to better position the workpiece to be processed, a positioning pin is arranged on the fixed disk.
[0005] In order to better fix the workpiece to be processed, a fixing plate is arranged on the bolt.
[0006] In order to facilitate the rotation and positioning of the fixed disk, a spring is arranged between the steel ball and the bolt.
[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: The tooth shape positioning angle of the utility model is accurate, the processing accuracy is improved, the quality of the product is effectively improved, and at the same time, the steps of continuously clamping and fixing the workpiece are avoided, which is beneficial to improving the production efficiency. The fixed disk is used for rotary indexing and steel ball positioning, which is convenient and fast. The structure is simple, the universality is wide, and it is beneficial to popularize and use. Brief Description of the Drawings

[0009] Figure 2 is Figure 1 the cross-sectional structural schematic diagram of
[0010] In the figure: base 1, column 2, fixed disk 3, fixing plate 4, nut 5, through hole 6, buckle 7, threaded rod 8, bearing seat 9, steel ball 10, spring 11, bolt 12, positioning pin 13. Detailed Description of the Embodiment
[0011] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.
[0012] In Figure 1 and Figure 2 a boring and positioning device for the outer circle of a gear ring, which comprises a base 1, a buckle 7 is arranged on the base 1, a column 2 is vertically and fixedly installed on the base 1, a bearing seat 9 is arranged on the column 2, a fixed disk 3 is installed on the bearing seat 9, a threaded rod 8 is fixedly arranged at the center of the fixed disk 3, a nut 5 is arranged on the threaded rod 8, a through hole 6 is arranged on the fixed disk 3, a bolt 12 is arranged at the bottom of the column 2, a steel ball 10 is arranged at one end of the bolt 12 close to the fixed disk 3, and a groove for accommodating the steel ball 10 is arranged on one side of the fixed disk 3 close to the column 2.
[0013] Furthermore, a positioning pin 13 is arranged on the fixed disk 3.
[0014] Furthermore, a fixing plate 4 is arranged on the bolt 12.
[0015] Furthermore, a spring 11 is arranged between the steel ball 10 and the bolt 12.
[0016] During use, the device is installed on the machine tool through the buckle 7 on the base 1, then the positioning hole on the workpiece is aligned with the positioning pin 13, and the workpiece is fixed through the fixing plate 4 and the nut 5. The machine tool drills the workpiece fixed on the fixed disk 3 through the through hole 6. When one hole is drilled, the fixed disk 3 is rotated. Since the steel ball 10 is spherical and a spring is arranged between the steel ball 10 and the bolt 12, when the fixed disk 3 rotates to a suitable position, the steel ball 10 enters the groove of the fixing plate 3 to limit the fixed disk 3 and prevent it from rotating during processing. At this time, another through hole 6 can be used to drill the workpiece again.
[0017] Since the through holes 6 on the fixed disk 3 can be preset as required, and the grooves for accommodating the steel balls 10 are correspondingly arranged according to the positions of the through holes 6, it is only necessary to fix the workpiece on the fixed disk 3 and rotate the fixed disk 3 after drilling one hole. This avoids the situation in the past where after drilling a hole, the workpiece needs to be removed from the fixture, measured, and then clamped and fixed again. This method is prone to poor machining accuracy, low yield, and low machining efficiency.
[0018] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
