Description

Technical Field

[0001] This utility model relates to the design and production of pneumatic support cylinder structures, and more specifically to a magnetic pneumatic support cylinder structure. Background Technology

[0002] Pneumatic support cylinders are used during workpiece processing to provide self-adjusting support force and compensate for unevenness of the workpiece surface and vibration and positional deviation generated during workpiece processing, preventing workpiece vibration and deformation during clamping.

[0003] Existing pneumatic support cylinder structures include Chinese patent: A Double-Locking Pneumatic Shaft Lock Structure, with authorization announcement number CN222296797U. This patent document discloses the specific content and usage of existing pneumatic shaft lock structures. As can be seen from the disclosed patent content, the pneumatic shaft lock uses the cooperation of guide sleeve, clamp, and locking piston to achieve rapid locking and unlocking of the shaft lock by utilizing pneumatic principles, thereby improving the stability and reliability of shaft lock operation.

[0004] Based on the existing structure, this application optimizes and designs the structure of the existing pneumatic support cylinder, which can improve the compactness of the pneumatic support cylinder, save its installation space, make it more aesthetically pleasing, and facilitate the assembly of the inlet and outlet air pipes, making it easy to inspect and maintain. Utility Model Content

[0006] The technical solution adopted in this utility model is as follows:

[0007] A magnetic pneumatic support cylinder structure is characterized by comprising a support cylinder body, an upper cover, a bottom cover, and a support shaft. The upper cover and bottom cover are respectively fitted onto the upper and lower parts of the support cylinder body. The support shaft is fitted onto the support cylinder body. A spring body is disposed inside the bottom cover, with its upper end connected to the lower end of the support shaft. A jacket, a sealing piston, a sealing ring, and a magnetic ring are disposed inside the support cylinder body. The sealing piston is sleeved on the outside of the jacket, and the jacket is movably clamped to the support shaft. The magnetic ring is fitted onto the lower part of the sealing piston. An air inlet and outlet hole is also provided on the support cylinder body, through which a high-pressure airflow drives the jacket to clamp the support shaft.

[0008] Furthermore, the jacket is fitted with a number of steel balls.

[0009] Furthermore, there are two sealing rings, which are respectively fitted and installed on the upper and lower parts of the outer side of the sealing piston.

[0010] Furthermore, the magnetic ring is connected to an external magnetic detection switch for positioning and controlling the stroke and movement nodes of the support shaft.

[0011] Furthermore, there are two spring bodies, which are symmetrically arranged on the left and right sides inside the bottom cover.

[0012] As can be seen from the above description and explanation of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0013] This utility model, by setting a spring body inside the bottom cover and setting a jacket, sealing piston, sealing ring and magnetic ring inside the support cylinder body, can not only achieve effective clamping support and provide greater support force, but also make the installation space more compact, and have a beautiful and practical appearance. At the same time, the air inlet can be easily connected to the external exposed pipe, which facilitates assembly and maintenance operations. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model.

[0015] The components include: a support cylinder body 1, an air inlet / outlet port 11, an upper cover 2, a bottom cover 3, a support shaft 4, a spring body 5, a jacket 6, a steel ball body 61, a sealing piston 7, a sealing ring 8, and a magnetic ring 9. Detailed Implementation

[0016] The specific embodiments of this utility model will be further described and illustrated below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, a magnetic pneumatic support cylinder structure is characterized by comprising a support cylinder body 1, an upper cover 2, a bottom cover 3, and a support shaft 4. The upper cover 2 and the bottom cover 3 are respectively fitted onto the upper and lower parts of the support cylinder body 1. The support shaft 4 is fitted onto the support cylinder body 1. A spring body 5 is provided inside the bottom cover 3. The upper end of the spring body 5 is connected to the lower end of the support shaft 4. There are two spring bodies 5, which are symmetrically arranged on the left and right sides inside the bottom cover 3.

[0018] like Figure 1As shown, the support cylinder body 1 is equipped with a jacket 6, a sealing piston 7, a sealing ring 8, and a magnetic ring 9. The sealing piston 7 is sleeved on the outside of the jacket 6, and the jacket 6 is movably clamped in cooperation with the support shaft 4. The magnetic ring 9 is fitted onto the lower part of the sealing piston 7. Several steel balls 61 are fitted inside the jacket 6. There are two sealing rings 8, which are respectively fitted onto the upper and lower parts of the outer side of the sealing piston 7. The support cylinder body 1 is also provided with an air inlet / outlet port 11. The high-pressure airflow input through the air inlet / outlet port 11 drives the jacket 6 to clamp the support shaft 4. The magnetic ring 9 is controlled and connected to an external magnetic detection switch for positioning and controlling the stroke and action nodes of the support shaft.

[0019] By setting a spring body 5 inside the bottom cover 3 and a jacket 6, sealing piston 7, sealing ring 8 and magnetic ring 9 inside the support cylinder body 1, not only can effective clamping and support be achieved, providing greater support force, but the installation space is also more compact, and the appearance is beautiful and practical. At the same time, the air inlet is convenient to connect with external exposed pipes, which facilitates assembly and maintenance operations.

[0020] When using it for work:

[0021] When airflow enters through the inlet / outlet 11, it pushes the sealing piston 7 to move along the support shaft 4 under the constraint of the jacket 6. As the sealing piston 7 moves, its inner wall interacts with the outer wall of the jacket 6, generating a radial locking force around the support shaft 4, thus firmly locking the support shaft 4. When unlocking is required, the inlet / outlet 11 is opened to expel the gas from the structure, causing the sealing piston 7 to return to its original position, releasing the locking force, and thus unlocking the structure.

[0022] During the locking process, the position of the magnetic ring 9 on the sealing piston 7 can be accurately detected by the externally installed magnetic detection switch, thereby accurately controlling the stroke and action nodes of the pneumatic shaft lock. Its pneumatic shaft lock is better applied to high-precision positioning scenarios on the production line.

[0023] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
