Large-diameter thin-walled ring parts are increasingly being used. Under specific product requirements, ordinary processing methods suffer from problems such as large processing deformation and difficulty in auxiliary positioning. For example, Chinese patent CN214722572U provides a ring part machining clamping fixture, including: a worktable, on which several sliding frames are evenly arranged around the center of the worktable, each sliding frame is fixed with a magnetic chuck, and at the center of the worktable is a sliding frame drive device that can drive each sliding frame to slide outward or retract inward simultaneously and equally at the same distance along the radial direction of the worktable, and on the worktable on both sides of each sliding frame is a T-shaped guide groove with an inward and outward orientation, and a fixing bolt passes through both sides of each sliding frame, each fixing bolt is threadedly connected to a nut located in the T-shaped guide groove, and a positioning mechanism is provided between each sliding frame and the worktable for quick positioning of the sliding frame. The tooling in the prior art mentioned above is too complex in structure and has a high manufacturing cost. In actual operation, foreign objects such as waste chips are generated when processing the ring parts, which can easily enter the sliding frame and other structures, affecting the operation. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary machining fixture for thin-walled ring parts, which solves the problems of existing fixtures having overly complex structures, high manufacturing costs, and the generation of foreign objects such as waste chips during ring part machining, which can easily enter complex structures such as sliding frames and affect the operation.

[0004] To achieve the above objectives, this utility model provides an auxiliary machining fixture for thin-walled ring parts. The auxiliary machining fixture for thin-walled ring parts includes a circular support base. The outer edge of the support base is recessed downward to form an annular groove. A fixing plate is provided on the surface of the support base by a first locking screw. The fixing plate extends at least partially above the annular groove. An L-shaped support seat is provided on the surface of the support base by a second locking screw. A long groove is provided on the horizontal section of the L-shaped support seat. The second locking screw passes through the long groove. The vertical section of the L-shaped support seat is close to the annular groove.

[0005] Preferably, the number of the long slots is not less than two sets;

[0006] The elongated groove is arranged along the radial direction of the support base.

[0007] Preferably, a flexible support block is fixed on the vertical section of the L-shaped support base.

[0008] Preferably, the flexible support block is a solid wood block and / or a rubber block.

[0009] Preferably, the plurality of fixed pressure plates are distributed at equal angles along the circumference of the support base;

[0010] The multiple L-shaped support bases are distributed at equal angles along the circumference of the support base.

[0011] Preferably, the plurality of fixed pressure plates and the plurality of L-shaped support seats are arranged alternately at intervals.

[0012] Beneficial effects: This utility model provides an auxiliary machining fixture for thin-walled ring parts. The auxiliary machining fixture for thin-walled ring parts includes a circular support base. The outer edge of the support base is recessed downward to form an annular groove. A fixing plate is provided on the surface of the support base through a first locking screw. The fixing plate extends at least partially above the annular groove. An L-shaped support seat is provided on the surface of the support base through a second locking screw. A long groove is provided on the horizontal section of the L-shaped support seat. The second locking screw passes through the long groove. The vertical section of the L-shaped support seat is close to the annular groove. During operation, the ring to be processed is placed on the support base. The ring has an inward-extending bottom forming an annular portion. The annular portion is engaged in the annular groove of the support base. Then, the first locking screw and the fixing plate are used to press the annular portion into the annular groove to prevent it from shaking in the vertical direction during processing. Then, the L-shaped support is slid so that its vertical section abuts against the inner wall of the ring. After that, when processing the upper and outer holes, grooves and other dimensional features of the thin-walled ring, the influence of workpiece deformation on the positioning and processing dimensions can be avoided.

[0013] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description
