Description

Technical Field

[0001] This utility model belongs to the field of tooling and fixture technology, and relates to a tooling and fixture for a rocking lathe. Background Technology

[0002] The tooling fixture for a gyratory lathe is used to clamp workpieces on a gyratory lathe, ensuring that the workpiece is in the correct machining position relative to the machine tool and cutting tool, and guaranteeing stability during the machining process.

[0003] Chinese patent publication number CN207139379U discloses a special tooling for a rocking car, including a T-shaped support and a limiting mechanism. The T-shaped support includes a base and a vertical plate. The base is used to connect with a chuck. The vertical plate has arc-shaped steps around its perimeter that mate with the inner arc surface of the rocking car's inner claw. The rocking car is limited by the limiting mechanism on the side of the vertical plate. A fastening mechanism is vertically provided in the middle of the vertical plate. A limiting hole is provided on the side of the vertical plate. A limiting bolt can pass through the through hole on the rocking car's protrusion and mate with the limiting hole. A fastening nut 1 mates with the limiting bolt to clamp and fix the protrusion. A pull rod is vertically located in the middle of the vertical plate. The pull rod can pass through the through hole in the middle of the rocking car, and the end of the pull rod is fastened to the vertical plate through an open washer and a fastening nut 2.

[0004] The special tooling for the swing-type turning arc provided by this patent achieves the overall rotation only by connecting the base and the chuck. If the centering is not accurate after connection, it will cause the tooling to be eccentric when rotating, affecting the roundness accuracy of the turning arc and making the workpiece rotation unstable. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a swing lathe tooling fixture.

[0006] The objective of this utility model can be achieved through the following technical solution: A gyratory lathe tooling fixture includes a mounting base, a positioning support plate, a connecting sleeve shaft, a transition connecting shaft, an upper fixture, and a lower fixture. The mounting base is disc-shaped and has a shaft through hole at its center. The connecting sleeve shaft is fixedly inserted into the shaft through hole. A limiting plate is formed on the upper end face of the connecting sleeve shaft, and a mounting cavity is formed in the connecting sleeve shaft. A connecting plate is formed at the upper end of the transition connecting shaft. The connecting plate has a frustum-shaped structure, and connecting arms are formed on both sides of the connecting plate. The transition connecting shaft is inserted into the mounting cavity and is connected to the connecting sleeve shaft. A fixing through hole is formed in the lower fixture. The connecting plate extends into the fixing through hole, and the transition connecting shaft is connected to the lower fixture. Symmetrical support connecting holes are formed in the mounting base. The positioning support plate is fixedly connected to the support connecting holes. The lower end of the lower fixture is in contact with the positioning support plate.

[0007] In the aforementioned oscillating lathe tooling fixture, a fixing rod is fixedly connected to the connecting arm, a fixing hole is provided in the mounting base, and the other end of the fixing rod passes through the fixing hole and is connected to the mounting base.

[0008] In the aforementioned oscillating lathe tooling fixture, the bottom of the mounting base has several mounting holes arranged in a straight line.

[0009] In the aforementioned oscillating lathe tooling fixture, a vertical rod assembly is fixedly connected to the mounting base, and a limit clamp and a limit baffle are provided on the mounting base on the rear side of the lower fixture.

[0010] Compared with the prior art, the tooling fixture for a rocking lathe provided by this utility model has the following beneficial effects: 1. The connecting sleeve shaft passes through the mounting base, and the connecting sleeve shaft can be connected to the external rotating connecting shaft. The mounting cavity opened in the connecting sleeve shaft can provide a high-precision mounting reference for the transition connecting shaft and the lower fixture, effectively reducing the centering error caused by the connection deviation between components; 2. The connecting sleeve shaft cooperates with the transition connecting shaft through the shaft through hole and the limiting plate. Combined with the connection of the connecting arm, the fixing rod and the mounting base, it can effectively resist the interference of cutting force, vibration and other factors, avoid relative displacement between components, and ensure the overall stability of this utility model in the rotation and machining process.

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figures 1 to 3As shown, this embodiment includes a mounting base 1, a positioning support plate 2, a connecting sleeve shaft 3, a transition connecting shaft 4, an upper clamp 5, and a lower clamp 6. The mounting base 1 is disc-shaped, with a shaft through hole 11 at its center. The connecting sleeve shaft 3 passes through and is fixed in the shaft through hole 11 by an interference fit, providing a stable foundation support for the subsequent assembly of components. A limiting plate 31 is formed on the upper end face of the connecting sleeve shaft 3, which can axially limit the components assembled on it. Simultaneously, an installation cavity 32 is formed inside the connecting sleeve shaft 3, reserving space for the installation of the transition connecting shaft 4. A connecting... The connecting plate 41 has a frustoconical structure. This structural design not only facilitates precise docking with other components but also enhances the structural strength of the connection. Connecting arms 42 are formed on both sides of the connecting plate 41. The transition connecting shaft 4 is inserted into the mounting cavity 32 and connected to the connecting sleeve shaft 3 through an interference fit, achieving stable assembly of the two. A fixed through hole 61 is provided in the lower clamp 6. The connecting plate 41 extends into the fixed through hole 61, and the transition connecting shaft 4 is connected to the lower clamp 6. Through the cooperation between the frustoconical connecting plate 41 and the fixed through hole 61, the accuracy and stability of the assembly of the lower clamp 6 are further improved.

[0015] To elaborate further, such as Figures 1 to 3 As shown, a fixing rod 7 is fixedly connected to the connecting arm 42, and a fixing hole 13 is provided in the mounting base 1. The other end of the fixing rod 7 passes through the fixing hole 13 and is connected to the mounting base 1. This connection method can effectively enhance the connection strength between the transition connecting shaft 4 and the mounting base 1, and resist the cutting force and vibration generated during the processing. Symmetrical support connecting holes 12 are provided in the mounting base 1, and the positioning support plate 2 is fixedly connected to the support connecting holes 12. The positioning support plate 2 plays a supporting and positioning role for the lower clamp 6, ensuring the stability of the lower clamp 6 during the processing.
