Description

Technical Field

[0001] This utility model relates to the field of ring workpiece processing technology, and more specifically, to a positioning fixture suitable for ring workpieces. Background Technology

[0002] Currently, tooling refers to process equipment, a general term for various tools used in the manufacturing process. In production, positioning tooling for ring-shaped workpieces is frequently used to position and fix them for machining. However, due to the thin sidewalls of ring-shaped workpieces, deformation can easily occur during machining, resulting in finished workpieces that do not meet quality requirements. In existing technologies, most positioning workpiece machining processes employ a dual-positioning method, requiring both an inner and an outer positioning structure. This makes the positioning and disassembly of ring-shaped workpieces cumbersome and inconvenient. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a positioning fixture suitable for ring-shaped workpieces, which is convenient for positioning and disassembling ring-shaped workpieces.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a positioning fixture suitable for ring-shaped workpieces, comprising:

[0005] Workbench;

[0006] The first positioning post is fixedly connected to the worktable, and the through hole of the annular workpiece can be fitted onto the first positioning post.

[0007] A stop is provided, which is adapted to a limiting part provided on the annular workpiece. The stop and the limiting part of the annular workpiece cooperate to prevent the annular workpiece from rotating.

[0008] The first positioning post and the stop component allow for precise positioning of the annular workpiece while preventing its rotation. Furthermore, installation and removal are simple: just fit the through hole onto the first positioning post and engage the limiting part and the stop component.

[0009] By setting the first positioning post on the worktable, in addition to positioning the ring-shaped workpiece, it can also abut against the through hole of the ring-shaped workpiece, providing support for the through hole and preventing the ring-shaped workpiece from deforming during processing.

[0010] Furthermore, the diameter of the first positioning post is adapted to the diameter of the through hole, and the first positioning post and the through hole are in a transition fit.

[0011] Furthermore, it also includes a positioning groove, the shape of which is adapted to the bottom surface of the annular workpiece, and the bottom surface of the annular workpiece can be accommodated within the positioning groove.

[0012] Furthermore, the width of the positioning groove is equal to or slightly greater than the wall thickness of the bottom surface, and the bottom surface can be engaged within the positioning groove.

[0013] Furthermore, the stop component includes a stop groove disposed on the worktable. The stop groove communicates with the positioning groove, and its position is adapted to the limiting protrusion on the annular workpiece. When the lower surface of the annular workpiece is accommodated in the positioning groove, the limiting protrusion on the annular workpiece can also be accommodated in the stop groove. The stop groove prevents the annular workpiece from rotating during processing, thus preventing inaccurate processing of the annular workpiece.

[0014] Furthermore, the stop component includes a second positioning post, which is disposed on the worktable. The second positioning post is positioned to match the limiting ring disposed on the annular workpiece. When the annular workpiece is fitted onto the first positioning post, the limiting ring can be fitted onto the second positioning post. The second positioning post further positions the annular workpiece and prevents it from rotating.

[0015] Furthermore, a processing device is provided on the worktable for processing the ring-shaped workpiece positioned on the worktable.

[0016] Furthermore, the processing device includes a cylinder, which is disposed on one side of the first positioning post, and the extension rod of the cylinder extends toward the first positioning post.

[0017] Furthermore, the cylinder is connected to the worktable via a lifting assembly, which can change the height of the cylinder on the worktable.

[0018] Furthermore, it also includes a positioning plate, which is perpendicular to the worktable and fixedly connected to it. The positioning plate fixes the worktable and positions it on other fixed devices, allowing the positioning fixture to flexibly select the installation position according to actual needs.

[0019] The beneficial effects of this utility model are:

[0020] 1) The first positioning post and the stop can position the annular workpiece while preventing it from rotating, ensuring accurate positioning. Furthermore, during installation and removal, it is only necessary to fit the through hole onto the first positioning post and engage the limiting part and the stop, making installation and disassembly convenient.

[0021] 2) By setting the first positioning post on the worktable, in addition to positioning the ring-shaped workpiece, it can also abut against the through hole of the ring-shaped workpiece to prevent the ring-shaped workpiece from deforming during processing. Attached Figure Description

[0030] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0031] See appendix Figure 1-5 As shown in the figure, this embodiment presents a positioning fixture suitable for annular workpieces, mainly used for positioning and processing annular workpieces 9. The positioning fixture includes a worktable 1, on which a first positioning post 2 is provided. The first positioning post 2 and the worktable 1 are fixedly connected. The first positioning post 2 and the worktable 1 can be integrally connected or detachably connected by bolts, depending on actual needs. When processing the annular workpiece 9, the through hole 91 of the annular workpiece 9 is fitted onto the first positioning post 2, and the position of the annular workpiece 9 is fixed by the first positioning post 2. Furthermore, the inner wall of the through hole 91 abuts against the first positioning post 2, and the first positioning post 2 supports the through hole 91, preventing the annular workpiece 9 from deforming towards the through hole 91 during processing.

[0032] In some embodiments, a positioning groove 3 is provided on the worktable 1. The shape of the positioning groove 3 is adapted to the bottom surface 92 of the annular workpiece 9. The bottom surface 92 of the annular workpiece 9 can be accommodated in the positioning groove 3. The bottom surface 92 of the annular workpiece 9 is fixed by the positioning groove 3, thereby positioning the annular workpiece 9.

[0033] If the lower bottom surface 92 of the annular workpiece 9 is circular, then the positioning groove 3 is an annular groove; if the lower bottom surface 92 of the annular workpiece 9 is elliptical, then the positioning groove 3 is an elliptical annular groove; if the lower bottom surface 92 of the annular workpiece 9 is cylindrical, then the positioning groove 3 is a circular groove. By matching the specific shape of the positioning groove 3 with the shape of the lower bottom surface 92 of the annular workpiece 9, the lower bottom surface 92 of the annular workpiece 9 can be accommodated in the positioning groove 3. The positioning groove 3 positions the annular workpiece 9, improving the positioning effect of the positioning fixture on the annular workpiece 9.

[0034] In some embodiments, the width of the positioning groove 3 is equal to or slightly greater than the wall thickness of the lower bottom surface 92, so that the lower bottom surface 92 can be engaged in the positioning groove 3, thereby improving the positioning effect of the positioning groove 3 on the annular workpiece 9. Slightly greater than the wall thickness ensures that the lower bottom surface can be accommodated in the positioning groove, and there is no gap between the lower bottom surface and the positioning groove.

[0035] In some embodiments, a stop groove 4 is provided on the worktable 1. The stop groove 4 communicates with the positioning groove 3 and is adapted to the position of the limiting protrusion 93 on the annular workpiece 9. When the lower bottom surface 92 of the annular workpiece 9 is engaged in the positioning groove 3, the limiting protrusion 93 on the annular workpiece 9 is accommodated in the stop groove 4. The stop groove 4 prevents the annular workpiece 9 from rotating during processing, thus preventing inaccurate processing of the annular workpiece 9.

[0036] In some embodiments, a second positioning post 5 is provided on the worktable 1, and the second positioning post 5 is located on one side of the first positioning post 2. The second positioning post 5 and the limiting ring 94 provided on the annular workpiece 9 are matched in position. When the annular workpiece 9 is sleeved on the first positioning post 2, the limiting ring 94 can be sleeved on the second positioning post 5. By setting the second positioning post 5, the annular workpiece 9 can be further positioned to prevent the annular workpiece 9 from rotating.

[0037] By setting the stop groove 4 and the second positioning post 5, the annular workpiece can be simultaneously limited to prevent it from rotating, resulting in a better limiting effect. On the other hand, as long as the annular workpiece includes a limiting protrusion 93 or a limiting ring 94, the positioning fixture can limit it to prevent rotation, thus making the annular workpiece suitable for the positioning fixture of this application, thereby expanding the applicability of the positioning fixture.

[0038] In some embodiments, a processing device is provided on the worktable 1 for processing the annular workpiece 9 positioned on the worktable 1. The processing device includes a cylinder 6, which is connected to the worktable 1 via a lifting assembly 7. The cylinder 6 is located on one side of the first positioning post 2, and the telescopic rod of the cylinder 6 extends in the direction of the first positioning post 2. The cylinder 6 can drive the telescopic rod to move in the direction of the first positioning post 2, which is also in the direction of the annular workpiece 9. During the movement in the direction of the annular workpiece 9, the annular workpiece 9 is processed, such as marking the annular workpiece 9.

[0039] The cylinder 6 is connected to the worktable 1 via the lifting assembly 7. The lifting assembly 7 can change the height of the cylinder 6 on the worktable 1, thereby changing the height at which the cylinder 6 processes the ring-shaped workpiece 9 and increasing the range of processing of the ring-shaped workpiece.

[0040] In some embodiments, a positioning plate 8 is also included. The positioning plate 8 is vertically arranged with the worktable 1 and is fixedly connected to the worktable 1. The worktable 1 is fixed by the positioning plate 8 and positioned on other fixed devices by the positioning plate 8, so that the positioning fixture can flexibly select the installation position according to actual needs.
