Description

Technical Field

[0001] The utility model belongs to the technical field of production of medical aluminum alloy gas cylinders, in particular to a fixed tooling for the production of aluminum alloy gas cylinders. Background Art

[0002] High-pressure lightweight aluminum cylinders can be used in many industries such as medical treatment, firefighting, beverages, lifesaving, diving, etc. With the improvement of people's living standards, maintenance and health are becoming more and more important. Regular supplementation of medical oxygen can delay the aging and onset of important organs such as the heart, brain, lungs, spleen, liver, and kidneys of the human body, and can reduce and postpone the onset of diseases and reduce the chance of sudden onset of chronic diseases. Compared with steel cylinders, aluminum cylinders have the advantages of light weight, good cleanliness, and beautiful appearance. The weight of medical aluminum alloy cylinders of the same specifications is about 1 / 3 of that of steel cylinders, making them more convenient to use and circulate.

[0003] At present, medical aluminum alloy gas cylinders are widely used in medical institutions to store and transport medical gases such as oxygen, nitrous oxide, and argon, providing necessary gas support for clinical diagnosis and treatment and emergency treatment. These gas cylinders usually undergo strict quality control and safety testing to ensure their safety and reliability during use.

[0004] During the processing of medical aluminum alloy gas cylinders, it is usually necessary to polish the inner and outer walls of the aluminum alloy gas cylinders, and they often need to be positioned during the polishing process.

[0005] The Chinese patent with the publication number "CN218427592U" discloses a gas cylinder inner wall polishing device, which includes a lifting assembly, the lifting assembly includes a lifting arm, the middle of the lifting arm is fixedly connected to a support shaft, both sides of the support shaft are provided with adjustment rods, the upper part of the adjustment rod passes through the lifting arm and is fixedly connected to a handle, the outer periphery of the adjustment rod is provided with a thread, the bottom of the adjustment rod is fixedly connected to a limit block, the first positioning block is slidably sleeved on the support shaft, the upper surface of the first positioning block is provided with a limit groove, and the limit block is limited in the limit groove. By this, the utility model can adjust the polishing diameter outside the gas cylinder to adapt to gas cylinders of different sizes, which is convenient to use; it is convenient for the polishing assembly to extend into the gas cylinder, and the gas cylinder can be clamped in the center to ensure that the polishing work is carried out accurately.

[0006] During use, the above-mentioned device uses a clamp to assist in clamping the gas cylinder as a whole. Although it can play a good polishing role on the entire interior of the gas cylinder, it still has certain shortcomings during its specific use. First, during the polishing process, the clamp will close and clamp the outside of the gas cylinder to fix it, which will block the outside of the gas cylinder, resulting in the inability to polish the outer surface of the gas cylinder during internal polishing. At the same time, the clamp is a rectangular structure as a whole. Since the gas cylinder is round, even if the size is different, it only changes its inner and outer diameters, and the whole is still round. A rectangular clamp is used to clamp and position the round gas cylinder. Since the circle has the characteristic of rolling instability, it is obviously impossible to stably and accurately clamp it. It is inconvenient to position and clamp during the polishing positioning process, and it is not convenient to insert the polishing structure into the gas cylinder. It can be seen that there are certain problems with the cap polishing equipment, so it needs to be improved. Utility Model Content

The mounting seat can be used to assist in the installation of external gas cylinder polishing equipment through the mounting groove and the mounting plate on the top of the mounting seat during use, which can improve the convenience and comprehensiveness of the device in polishing processing.

[0036] Principle and advantages of use: By setting the clamping mechanism 4, the gas cylinder to be processed can be placed in the middle of the top of the fixing seat 2 during use of the device, and the screw rod 42 is driven to rotate by the first motor 41. The screw rod 42 can assist in driving the slider 43 to slide inside the slide groove 3. Since the threads at both ends of the slide groove 3 rotate in opposite directions, the slider 43 can be assisted in reciprocating inside the slide groove 3. The reciprocating movement of the slider 43 can flexibly adjust the two groups of support rods 44 to slide against each other. The sliding of the two groups of support rods 44 against each other can drive the clamping seat 45 to move against each other. The displacement of the clamping seat 45 against each other can adjust the gas cylinders of different thicknesses. The gas cylinder is clamped and positioned, and a clamping groove 46 is provided on the inner side of the clamping seat 45. The overall shape of the clamping groove 46 is V-shaped, and there is an inclined surface inside. When the clamping groove 46 clamps the gas cylinder, the inclined surface inside the clamping groove 46 can assist in contacting the gas cylinder. Since the sliders 43 are synchronously displaced with each other, the gas cylinder can be positioned in the middle of the two groups of clamping grooves 46, and the clamping groove 46 can be centered. The inner side of the clamping seat 45 forms a diamond shape, which can stably fit gas cylinders of different sizes and thicknesses, and can avoid the rolling of the gas cylinder. It can improve the stability of the overall clamping of the gas cylinder, and facilitate the rapid centering and positioning of gas cylinders of different sizes.

[0037] By setting the driving mechanism 5, during use, when the gas cylinder is clamped, the sliding block 53 inside the side rail 51 can be pushed to slide by starting the electric push rod 52, and the concave seat 54 can be driven to move toward the gas cylinder by the sliding block 53, so that the outer surface of the driving wheel 57 inside the concave seat 54 can be made to fit the outer surface of the gas cylinder. At this time, by starting the second motor 55, the second motor 55 drives the rotating shaft 56 to rotate, and the rotation of the rotating shaft 56 can drive the driving wheel 57 to rotate. The rotation of the driving wheel 57 and the fitting of the driving wheel 57 and the gas cylinder can assist in driving the gas cylinder to rotate on the inner side of the clamp seat 45, and the ball 47 is arranged on the inner side of the clamp seat 45, which can promote the stable rotation of the gas cylinder. In this process, the side of the gas cylinder away from the driving wheel 57 is in an exposed state. At this time, the external polishing device at the front end and the gas cylinder inner wall polishing device at the top thereof are synchronously polished, which is convenient for adapting to the polishing of the inner and outer walls of the gas cylinder, and can simultaneously Comprehensive processing of the entire gas cylinder can improve the convenience and efficiency of gas cylinder processing. During specific use, the inner wall polishing structure can use the inner wall polishing structure in a gas cylinder inner wall polishing device with the publication number "CN218427592U". Since the front side of the mounting seat 1 is provided with a mounting groove 8 and a mounting hole 7, it can assist in installing the polishing structure in the above technical scheme, and can realize polishing processing of the inner wall of the gas cylinder. As for the outer wall polishing structure, a transverse slide is installed on the top of the mounting plate 9, and a longitudinal slide is installed on the top of the transverse slide. A corresponding polishing friction plate is installed on the side of the longitudinal slide close to the clamping mechanism 4. At this time, the transverse slide can be used to push the polishing plate to contact the gas cylinder. At the same time, the longitudinal slide can adjust the polishing plate to move up and down, which can assist in polishing its outer surface. The longitudinal slide and the transverse slide are linear modules of the existing technical means. The polishing of the inner and outer walls can be carried out by the existing polishing means, so they are not repeated here.
