Description

Technical Field

[0001] This utility model relates to the field of metal shell processing technology, and in particular to a pneumatic guide fixture for metal shell processing. Background Technology

[0002] Currently, most commonly used metal casing machining fixtures on the market are manual or traditional mechanical transmission structures. Manual fixtures rely on manual operation to clamp and release, which is not only labor-intensive and inefficient, but also prone to unstable clamping force due to uneven manual force control, thus affecting machining accuracy and even causing damage to the casing surface. Traditional mechanical transmission fixtures, although eliminating direct manual operation, mostly use cam, lead screw and other transmission structures, which have problems such as complex structure and low guiding accuracy. After long-term use, the parts are prone to wear, resulting in decreased clamping stability, and it is difficult to quickly adapt to the clamping needs of metal casings of different sizes, resulting in poor flexibility. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a pneumatic guide fixture for machining metal shells.

[0004] This utility model proposes a pneumatic guide clamp for processing metal shells, including a base body. Several cylinders are installed inside the base body. Each cylinder's telescopic end is rotatably connected to a swing arm. The swing arm has a guide hole inside and a chuck is integrally connected to its top end. The guide hole is a waist-shaped hole structure with an inclined angle in the middle. A guide rod is fixed to the top of the base body. The guide rod passes through the guide hole so that, under the guiding action, it drives the swing arm and the chuck to swing in a vertical plane, thereby loosening and clamping the metal shell.

[0005] Furthermore, a pad is symmetrically installed at the top of the seat, and the metal shell is located on top of the pad.

[0006] Furthermore, a through hole is provided at the top of the seat, and the swing arm swings inside the through hole, with the length of the through hole being greater than the length of the swing arm's swing stroke.

[0007] Furthermore, a limiting groove is provided at the top of the base, and the limiting groove is symmetrically arranged on both sides of the through hole and connected to the through hole.

[0008] Furthermore, the guide rod is located inside the limiting groove to constrain the horizontal position of the guide rod.

[0009] Furthermore, the top of the seat is symmetrically provided with stepped grooves, which are connected to the limiting grooves, and the height of the stepped grooves is higher than that of the limiting grooves.

[0010] Furthermore, a pressure plate is fixedly installed inside the stepped groove to constrain the vertical position of the guide rod.

[0011] The beneficial effects of this utility model are as follows: Power is provided by the internal cylinder of the base, and the precise guiding structure of the waist-shaped guide hole with an inclined angle in the middle of the swing arm and the guide rod at the top of the base replaces the traditional manual operation and complex mechanical transmission methods such as cams and lead screws. On the one hand, there is no need for direct manual participation in clamping and loosening actions, which greatly reduces labor intensity. Moreover, the cylinder driving force is stable and controllable, which can avoid the fluctuation of clamping force caused by uneven manual force, effectively ensuring processing accuracy, preventing damage to the surface of the metal shell, and significantly improving operating efficiency. On the other hand, the overall structure is simplified, reducing the number of easily worn parts in traditional mechanical transmission, extending the service life of the fixture, and by adjusting the cylinder extension stroke and adapting to different chucks, the clamping needs of metal shells of different sizes can be quickly met, improving the flexibility and adaptability of the fixture. This solves the problems of high labor intensity, low efficiency, poor accuracy, complex structure, low stability and insufficient flexibility of traditional fixtures. Attached Figure Description

[0014] Reference Figure 1-5 This utility model proposes a pneumatic guide clamp for processing metal shells, including a base 1. Inside the base 1, several cylinders 2 are installed according to processing requirements. The telescopic end of each cylinder 2 is rotatably connected to a swing arm 3 via a rotating shaft. The swing arm 3 has a guide hole 31 inside, and the top end is connected to a chuck 32 by an integral molding process. The integral molding design can effectively improve the structural strength of the connection between the chuck 32 and the swing arm 3, and avoid the problem of breakage or loosening at the connection during long-term clamping operations. The bottom of the metal shell 6 has a hollow opening, and the opening is surrounded by rolled edges. The chuck 32 clamps and fixes the metal shell 6 by clamping the rolled edges.

[0015] The guide hole 31 is specially designed as an oblong hole structure with an inclined angle in the middle. This special structure is the key design to achieve precise swing of the swing arm 3. Correspondingly, a guide rod 4 is fixedly installed on the top of the base 1. The guide rod 4 cooperates with the guide hole 31 and is precisely inserted into the guide hole 31. When the piston rod of the cylinder 2 extends or retracts, it will drive the swing arm 3 to move up or down. At this time, under the interaction of the guide rod 4 and the guide hole 31 with the inclined oblong hole structure, the movement trajectory of the swing arm 3 is constrained, thereby driving the swing arm 3 and the chuck 32 to swing stably in the vertical plane. Specifically, when the piston rod of the cylinder 2 extends, the swing arm 3 drives the chuck 32 to swing away from the metal shell 6, realizing the release action of the metal shell 6. When the piston rod of the cylinder 2 retracts, the swing arm 3 drives the chuck 32 to swing towards the metal shell 6, completing the clamping action of the metal shell 6, thereby realizing the precise clamping and release of the metal shell 6. To further optimize the performance of the fixture, a pad 5 is symmetrically installed on the top of the base 1, and a metal shell 6 is placed on the top of the pad 5. The pad 5 can be made of a material with moderate hardness and certain wear resistance. On the one hand, it can prevent the metal shell 6 from directly contacting the top of the base 1 and reduce the wear on the surface of the base 1. On the other hand, by replacing the pad 5 with different thicknesses, it can be adapted to metal shells 6 with different height specifications, thereby improving the versatility of the fixture. A through hole 11 is provided at the top of the seat 1. The swing arm 3 swings inside the through hole 11. The length of the through hole 11 is designed to be greater than the swing stroke of the swing arm 3. This design provides the swing arm 3 with sufficient swing space, effectively avoiding collision and interference between the swing arm 3 and the seat 1 during the swing process, and ensuring the smoothness of the swing arm 3's movement. The top of the base 1 also has a limiting groove 12, which is symmetrically arranged on both sides of the through hole 11 and connected to the through hole 11. The guide rod 4 is installed inside the limiting groove 12. The limiting groove 12 can accurately constrain the horizontal position of the guide rod 4, preventing the guide rod 4 from shifting horizontally during operation, ensuring that the guide rod 4 always maintains a stable fit with the guide hole 31, thereby ensuring the accuracy of the swing trajectory of the swing arm 3 and avoiding deviation of the clamping position due to the offset of the guide rod 4. At the same time, the top of the base 1 also has A stepped groove 13 is symmetrically provided, which is connected to the limiting groove 12. The height of the stepped groove 13 is higher than that of the limiting groove 12. A pressure plate 14 is fixedly installed inside the stepped groove 13 by bolts or other fasteners. The pressure plate 14 can effectively constrain the vertical position of the guide rod 4, prevent the guide rod 4 from moving vertically during its movement in conjunction with the guide hole 31, further improve the stability of the guide rod 4 installation, ensure the reliable performance of the guiding function, and thus ensure the accuracy and stability of the entire clamping action.
