Description

Technical Field

[0001] This utility model relates to the technical field of turning fixtures, and in particular to a special fixture structure for turning multi-angle ring plates. Background Technology

[0002] In the current field of machining, ring-shaped parts are widely used in key components such as sealing, buffering, and transmission due to their structural symmetry and rotational characteristics. However, due to functional requirements, the end faces or outer circumferential surfaces of some ring-shaped parts are often designed with multiple different slopes. This multi-slope structure greatly increases the difficulty of clamping the ring during turning. If conventional flat fixtures are used, they cannot effectively fit the slopes, which can easily lead to problems such as unstable clamping, workpiece displacement, or even machining deformation.

[0003] In actual production, temporary shims and manual adjustment of support angles are commonly used to assist in clamping these multi-angle ring pieces. However, this method is highly dependent on the operator's experience, the adjustment process is cumbersome and lacks repeatability, seriously affecting processing efficiency and accuracy. In addition, due to the precise structure of the ring piece itself, the stability requirements for positioning and clamping are high. If the fixture cannot provide reliable support and restraint, it will directly affect the turning accuracy and product consistency, and may even lead to the scrapping of parts.

[0004] In view of this, the inventors specifically designed a special fixture structure for turning multi-angle ring plates, which led to this invention. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this application is to provide a special fixture structure for turning multi-sloping ring pieces, which at least solves the problems of unstable clamping and low clamping efficiency caused by the multi-sloping structure in the existing ring-type parts turning process.

[0007] In a further embodiment, the slide is a T-shaped groove, and the bottom of the positioning seat is provided with a slider that cooperates with it, and the locking and positioning are achieved by screws.

[0008] In a further embodiment, the support block is rotatably connected to the positioning seat via a rotating shaft, and the support block is fitted with a screw-on knob for locking the support angle.

[0018] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] This utility model discloses a special fixture structure for turning multi-angle ring pieces. This fixture structure is particularly suitable for turning ring workpieces with multiple surfaces having different inclination angles. It has the advantages of compact structure, convenient operation, strong adaptability, and stable clamping. It can effectively improve processing efficiency and finished product accuracy, and reduce workpiece damage and scrap rate.

[0020] like Figure 1 As shown, the fixture structure includes a base 1, a positioning seat 2, a support block 3, a clamping device 5, a positioning pin 6, and an auxiliary support assembly 7, among other cooperating components. The specific construction is as follows: The base 1 is an integral frame structure, providing overall rigid support and a mounting foundation. Its upper surface has one or more sliding grooves 11, each a T-slot, for mating with the positioning seat 2. The T-slot provides good guidance and sliding stability, allowing the positioning seat 2 to slide back and forth along its direction. A slider 12 located at its bottom is embedded in the T-slot, achieving low-friction positioning adjustment. The slider 12 and the T-slot are secured with screws to ensure the positioning seat 2 remains stationary.

[0021] The positioning seat 2 is the core component for installation and adjustment in the fixture. An adjustable support block 3 is mounted on it. This support block 3 is rotatably connected to the side wall of the positioning seat 2 via a rotating shaft 21, allowing it to swing around a horizontal axis. The support block 3 is a wedge-shaped or ramp structure with a supporting surface, used to support the bottom of the inclined surface of the ring piece. The support block 3 has an adjustment mechanism 4 inside, such as a hand-tightening knob 22 and an arc-shaped slide groove 11 that work in conjunction with the main body, allowing the support block 3 to be precisely adjusted to an angle consistent with the inclined surface of the workpiece, and locked in place by the hand-tightening knob 22 to maintain stability.

[0022] like Figure 2As shown, to ensure the stability and safety of the ring during processing, the fixture is further equipped with a clamping device 5. This device is preferably located on top of the positioning seat 2 and consists of a pressure plate 51 and a screw assembly 52. ​​The screw assembly 52 includes a knob 521, a guide screw 522, and a limiting retaining ring 523. The knob 521 is used for manual tightening by the operator. The guide screw 522 passes through the pressure plate 51 and is threadedly connected to the base 1 or the positioning seat 2, enabling the pressure plate 51 to move up and down. When the pressure plate 51 presses against the upper surface of the ring, it reliably clamps it, preventing shaking or detachment during high-speed turning. To prevent damage to the ring due to excessive clamping force, an elastic limiting sleeve 8 is provided between the pressure plate 51 and the base 1, which can buffer the clamping force, absorb some vibration, and increase the stability of the clamping.

[0023] To limit the rotation of the ring, the positioning seat 2 is provided with one or more positioning pins 6. The positioning pins 6 are preferably cylindrical pins that can be inserted into the inner hole or edge limiting hole of the ring to form axial or radial physical limits, effectively preventing the workpiece from rotating under clamping conditions. The positioning pins 6 can also be replaced by screws or slots to accommodate rings of different sizes and structures.

[0024] like Figure 1 and Figure 2 As shown, to improve overall stability and support balance during clamping, the clamping structure also includes an auxiliary support assembly 7. This assembly is mounted on the base 1, located opposite the main support block 3, and is mainly used to support the outer edge of the ring piece or the other inclined surface. The top block 71 in the auxiliary support assembly 7 is connected to the base 1 through a threaded lifting structure 9. The operator can adjust the height of the top block 71 through the handle 91 to make it precisely fit the outer inclined surface of the workpiece, forming a stable support. Preferably, the auxiliary support assembly 7 can be provided with two or more top blocks 71, and arranged symmetrically along the outer circumference of the ring piece to enhance the support capacity for large ring pieces or multi-point inclined surfaces.

[0025] Through the coordinated operation of the above structures, this clamp not only enables rapid clamping of ring pieces with various inclined plane angles, but also possesses excellent adjustability and versatility. Operators only need to adjust the support angle, clamping height, and auxiliary support position according to the specific structure of the ring piece to reliably clamp different ring pieces. The entire clamping process does not rely on specialized tools, making it convenient and quick.

[0026] In addition, all components of this fixture are modularly designed, which facilitates disassembly, maintenance, replacement and upgrades. It is suitable for batch processing, flexible production lines and high-precision CNC machining equipment, and has strong promotion and application value.

[0027] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
