Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of workpiece processing devices, in particular to an annular thin-walled workpiece processing tool. Background Art
[0002] Annular thin-walled workpieces are common parts with circular or nearly circular cross-sections and relatively thin walls. Due to their special structure, they are prone to deformation and instability during processing, and traditional external clamping processing methods often cannot meet the requirements for workpiece processing.
[0003] Traditional annular thin-wall processing tooling generally adopts an external clamping method, which fixes the workpiece on the outside through a fixture and then processes it. However, due to the characteristics of the annular thin-wall workpiece itself, external clamping can easily cause the workpiece to deform, affecting the processing accuracy and surface quality. At the same time, the stability of the external clamping is also poor. Once deformed, it will detach, which is prone to risks and accidents. Utility Model Content
[0004] In order to solve the above-mentioned various problems, the utility model provides a processing tool for an annular thin-walled part.
[0005] In order to solve the above technical problems, the technical solution of the utility model is: a kind of annular thin-walled parts processing tooling, including a base and an L-shaped frame fixedly arranged on the upper end face of the base, mounting plates are fixedly arranged on the left and right sides of the base, an internal thread column is fixedly arranged at the center of the upper end face of the base, and arc-shaped plates are slidably arranged on the upper end face of the base and on the left and right sides of the internal thread column, a vertical rod is movably inserted at the upper end of the L-shaped frame, an external thread is arranged at the lower end of the vertical rod, and an expanding cone is rotatably arranged at the lower end of the vertical rod and located above the external thread, the tip of the expanding cone faces downward and the radius of the lower end face is smaller than the radius of the arc plate.
[0006] Furthermore, grooves are provided on the upper end surface of the base and on both sides of the internal threaded column. A sliding rod is fixed inside the groove, and a slider is slidably provided on the sliding rod. The slider is slidably connected to the groove, and the arc plate is fixed to the upper end of the slider.
[0007] Furthermore, a return spring is sleeved on the two slide bars and located outside the slide block.
[0008] Furthermore, a bearing is fixedly provided on the vertical rod, and the expanded diameter cone is fixedly provided on the outer ring of the bearing.
[0009] Furthermore, the external thread at the lower end of the vertical rod cooperates with the internal thread column thread, and a turntable is fixedly provided at the upper end of the vertical rod.
[0010] Compared with the prior art, the utility model has the following advantages: the utility model patent provides a new type of annular thin-walled parts processing tooling that combines internal threaded columns, arc plates, vertical rods, expanded truncated cones and other components, and achieves stable fixation of the workpiece by internal clamping. The arc plate fixes the workpiece from the inside to the outside of the workpiece, so that the workpiece can always maintain a stable posture during the processing process, effectively avoiding the deformation problem caused by external clamping. At the same time, the design of components such as sliding rods, sliders and reset springs makes the tooling operation more flexible and convenient. After the processing is completed, the expanded truncated cone is raised, and under the reset action of the spring, the arc plate can be immediately retracted to the center, making the workpiece easier to pick up.
