Description

Technical Field

[0001] This utility model relates to the field of mechanical auxiliary support technology, and in particular to a small pneumatic auxiliary support device. Background Technology

[0002] In fields such as machining and electronic component assembly, auxiliary support devices are key components for ensuring the stability of workpiece positioning. Existing auxiliary support devices have two main problems: one type is large in size, making it difficult to adapt to the compact assembly scenarios (such as electronic component assembly machines) and prone to interference with other components; the other type, although small in size, has insufficient supporting force, which can easily lead to unstable support during workpiece processing or assembly, resulting in workpiece displacement and affecting machining accuracy or assembly quality.

[0003] Meanwhile, some traditional support devices use manual locking, which is inefficient and difficult to control in terms of locking force. While some pneumatic support devices achieve automated operation, their structural design is flawed, resulting in components prone to corrosion and short service life. This is especially problematic in environments containing cutting fluid or dampness, where impurities or component corrosion can easily lead to malfunctions. Therefore, there is an urgent need for a compact, high-capacity, easy-to-operate, and durable auxiliary support device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a small pneumatic auxiliary support device that solves the problems of large size and insufficient support force, low operating efficiency, and poor durability of existing auxiliary support devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A small pneumatic auxiliary support device includes an aluminum alloy body, a shaft, a clamping rod, a piston, and a shaft locking interface. The shaft passes through the upper end face of the aluminum alloy body and is connected to the piston. The clamping rod is located on one side of the shaft and cooperates with the shaft to assist in fixing the workpiece when the shaft is locked. The shaft locking interface is located on the lower end of one side of the outer wall of the aluminum alloy body and is connected to a pneumatic channel inside the aluminum alloy body. It is used to connect compressed air to drive the piston to drive the shaft to achieve locking or unlocking actions.

[0007] Furthermore, the aluminum alloy body is made of A5052 type aluminum alloy with aluminum oxide film surface treatment, the shaft and clamping rod are made of S45C electroless nickel plating, and the piston is made of A5056 type aluminum alloy with aluminum oxide film surface treatment.

[0008] Furthermore, a spring is installed between the piston and the aluminum alloy body.

[0009] Furthermore, the travel of the shaft is within a preset range, and the travel is adapted to a 4mm specification.

[0010] Furthermore, the specifications of the shaft locking interface are: M3×0.5, wherein the air pressure supported is 0.4-0.7MPa, and the overall support force is 20-40N.

[0011] Furthermore, a first mounting hole is provided on both sides of the front end face of the aluminum alloy body near the midpoint, and a second mounting hole is provided on both sides of the lower end face of the aluminum alloy body near the midpoint.

[0012] This utility model has the following beneficial effects:

[0013] 1. Balance between size and support force: It adopts a compact structural design, making the body small and suitable for scenarios with limited space (such as electronic component assembly machines); at the same time, through reasonable material selection and structural optimization, it can provide a support force of 20-70N, which can meet the support needs of most small workpieces and solve the contradiction of "small size means insufficient support force".

[0014] 2. Easy to operate: The shaft can be locked and released by connecting compressed air through the shaft locking interface, eliminating the need for manual operation and improving operational efficiency; moreover, the air pressure control method can achieve automated integration and adapt to the automation needs of the production line.

[0015] 3. High durability: The body and piston are made of aluminum alloy and treated with aluminum oxide film surface treatment. The shaft and clamping rod are treated with S45C electroless nickel plating, which has good corrosion resistance and wear resistance, extending the service life of the device in complex environments (such as scenarios containing a small amount of cutting fluid).

[0016] 4. Flexible installation: It supports both side and bottom installation, allowing users to choose the installation location based on the actual scenario, thus improving the device's adaptability.

[0017] 5. Good stability: The piston is driven by air pressure to move the shaft, which has a stable locking force and avoids the problem of uneven force caused by manual operation; and the built-in spring can drive the shaft to accurately reset when the air pressure is released, ensuring the stability of the next use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 The present invention provides an embodiment of a small pneumatic auxiliary support device, comprising an aluminum alloy body 3, a shaft 1, a clamping rod, a piston 2, and a shaft locking interface 6. The shaft 1 passes through the upper end face of the aluminum alloy body 3 and is connected to the piston 2. The clamping rod is located on one side of the shaft 1 and cooperates with the shaft 1 to assist in fixing the workpiece when the shaft 1 is locked. The shaft locking interface 6 is opened on the lower end of one side of the outer wall of the aluminum alloy body 3 and is connected to the air pressure channel opened inside the aluminum alloy body 3. It is used to access compressed air to drive the piston 2 to drive the shaft 1 to achieve locking or unlocking action.

[0027] Specifically, the aluminum alloy body 3 is made of aluminum alloy (A5052) with an aluminum oxide film treatment on the surface. The aluminum alloy material reduces the weight of the body, achieving the design goal of "compactness"; the aluminum oxide film treatment forms a dense protective film, improving the corrosion resistance of the body, preventing rusting in humid environments or in contact with small amounts of cutting fluid, and ensuring the structural stability for long-term use.

[0028] Shaft 1 and clamping rod: Shaft 1 is made of S45C steel and electroless nickel-plated. S45C is a high-quality carbon structural steel with high strength and hardness, capable of withstanding the pressure of the workpiece and the impact force during shaft movement. The electroless nickel plating layer is uniform and has strong adhesion, further improving the wear resistance and corrosion resistance of shaft 1, ensuring that shaft 1 is not easily worn during repeated extension and retraction. The clamping rod cooperates with shaft 1 to assist in fixing the workpiece when the shaft is locked, preventing the workpiece from slipping.

[0029] Piston 2 is made of aluminum alloy (A5056) with an aluminum oxide film surface treatment. A5056 aluminum alloy has higher strength than A5052, which is suitable for the reciprocating motion requirements of piston 2 under pneumatic drive. The aluminum oxide film treatment also improves its corrosion resistance, and the aluminum alloy material is compatible with the body material, reducing wear caused by friction between piston 2 and the inner wall of the body, and extending service life.

[0030] Shaft locking interface 6: Uses AMNS06-S model interface (M3×0.5) or AMNS08-S model interface (M4×0.7) for connecting external pneumatic lines. The interface specifications match the corresponding model's pneumatic pressure requirements, ensuring a stable input of compressed air to power piston 2. The threaded design ensures a tight connection, preventing insufficient driving force due to air leakage.

[0031] Built-in spring: The spring is located between the piston and the body. When the air pressure is released, the spring force pushes the piston to reset the shaft. Its function is to ensure that the shaft returns to its initial position after each release of air pressure, avoiding shaft position deviation from affecting the accuracy of the next workpiece placement and improving the repeatability and stability of the support.

[0032] Work process and results:

[0033] Taking the AMNS06-S model as an example, its working process is as follows:

[0034] The workpiece is placed on the shaft 1 of the support device. At this time, the shaft 1 moves slightly under the weight of the workpiece, and the built-in spring is compressed accordingly. The top of the shaft 1 is in close contact with the surface of the workpiece, thus initially achieving workpiece support.

[0035] External clamping components, in conjunction with clamping rods, assist in clamping the workpiece to prevent it from sliding laterally.

[0036] Compressed air at 0.4-0.7MPa is introduced through the shaft locking interface 6 (M3×0.5). The air pressure pushes the piston 2 to fix the shaft 1. The shaft 1 is locked, and the supporting force reaches 20-40N, which is sufficient to stably support the workpiece.

[0037] After the workpiece is processed or assembled, the air pressure is released, and the built-in spring pushes the piston 2 to drive the shaft 1 to reset, so that the workpiece can be removed.

[0038] During this process, the air pressure range of 0.4-0.7MPa can stably output a supporting force of 20-40N, which will not cause the workpiece to shake due to insufficient supporting force, nor will it damage small workpieces (such as electronic components) due to excessive supporting force. The pneumatic drive makes the locking action respond quickly, saving more than 50% of the operation time compared to manual locking. Moreover, the corrosion-resistant and wear-resistant design of each component allows the device to have a service life of more than 3 years under continuous use for 8 hours a day, which is far longer than the traditional support device without surface treatment (approximately 1 year service life).

[0039] Installation instructions:

[0040] Side mounting: Mounting holes (4) are opened on both sides of the front end face of the aluminum alloy body 3 near the midpoint. The body is fixed to the side of the fixture plate by bolts through the mounting blocks. The bolts pass through the mounting holes 4 for fixed installation. This is suitable for scenarios where the workpiece is fed in from the side. The connection position between the mounting block and the body has been optimized for stress. The bolt connection strength can withstand the support force transmitted by the shaft, avoiding loosening of the mounting part.

[0041] Bottom mounting: Mounting holes 5 are provided on both sides of the lower end face of the aluminum alloy body 3 near the midpoint. Bolts are then passed through these holes from bottom to top, directly fixing the bottom of the body to the fixture plate. This method is suitable for scenarios where the workpiece is placed from above. Bottom mounting increases the contact area between the body and the fixture plate, resulting in better support stability, and is especially suitable for situations requiring high support forces (such as those approaching 40N).

[0042] Both installation methods require no complicated auxiliary tools, and the installation process only takes 5-10 minutes, demonstrating the ease of installation of the device.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
