Technical Field
[0001] This utility model relates to the field of pipe clamping technology, specifically a vacuum adsorption cutting clamp for brittle alloy pipes. Background Technology
[0002] In modern industrial production, brittle alloy tubing, due to its unique physical and chemical properties, is widely used in aerospace, electronics, chemical, and many other fields. However, its brittle material characteristics pose significant challenges to the cutting process. Traditional mechanical clamping methods for cutting fixtures, such as chucks and clamps, inevitably apply considerable localized pressure to the tubing surface when fixing it. This localized pressure easily leads to indentations on the tubing surface, which can become stress concentration points during subsequent use, reducing the overall strength and service life of the tubing. More seriously, excessive localized pressure often causes cracks on the tubing surface, or even leads to tubing breakage during the cutting process. This not only results in the scrapping of a large amount of raw materials and increases production costs, but also seriously affects production efficiency and product quality. Furthermore, with the diversification and refinement of industrial production, the demand for brittle alloy pipe diameters is becoming increasingly diverse. Traditional clamps exhibit extremely poor adaptability when dealing with brittle alloy pipes of different diameters. When changing pipe specifications is required, operators often need to spend a significant amount of time and effort adjusting the clamp structure, and may even need to replace the entire clamp, which undoubtedly greatly reduces production efficiency and increases production complexity and cost. Therefore, developing a cutting clamp that can effectively avoid damage to brittle alloy pipes while flexibly adapting to various pipe diameters has become a crucial problem urgently needing to be solved in current industrial production. To address this, a vacuum adsorption cutting fixture for brittle alloy tubing is provided. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a vacuum adsorption cutting fixture for brittle alloy pipes, thereby solving the problems mentioned in the background section.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a vacuum adsorption cutting fixture for brittle alloy pipes, including a mounting base, an elastic band provided on one side of the mounting base, hinge seats fixedly connected to both ends of the elastic band, the hinge seats being hinged to one end of the mounting base, and a rubber suction cup sleeve fixedly connected to a groove at one end of the hinge seat, a suction tube fixedly connected to one side of the rubber suction cup sleeve, and a pressure main pipe fixedly connected between the two suction tubes.
[0005] Preferably, one end of the mounting base is provided with an arc-shaped through structure.
[0006] Preferably, the mounting base has two slots on its exterior in a symmetrical structure, one of which is fitted with a debris collection box.
[0007] Preferably, one end of the debris collection box has two outer support plates hinged to it in a symmetrical structure, and an elastic rope is fixed between the two outer support plates. One end of each outer support plate is configured with a bent structure.
[0008] Preferably, a lower frame is fixed to one side of the outer support plate.
[0009] Preferably, one end of the rubber suction cup sleeve is arranged in an arc shape.
[0010] This invention provides a vacuum adsorption cutting fixture for brittle alloy tubes. Compared with the prior art, it has the following advantages: 1. The vacuum adsorption cutting fixture for brittle alloy pipes uses a vacuum adsorption system consisting of a rubber suction cup sleeve, a suction tube, and a pressure main tube to stably adsorb the pipes using negative pressure, avoiding direct compression of the pipe surface and effectively preventing damage such as indentations and cracks on the pipe surface. This significantly improves the processing quality and yield of brittle alloy pipes.
[0011] 2. The vacuum adsorption cutting fixture for this brittle alloy pipe is connected to the mounting base via a hinged seat. One end of the rubber suction cup sleeve has an arc-shaped structure. This design allows the fixture to adaptively adjust according to the pipe diameter by stretching the elastic band and rotating the hinged seat. It can quickly adapt to brittle alloy pipes of various diameters without complicated structural adjustments, greatly improving production efficiency. Attached Figure Description

[0014] 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, other embodiments obtained by those of ordinary skill in the art without creative effort are all within the scope of protection of the present utility model.
[0015] Please see Figure 1-3 As shown, this utility model provides a technical solution: a vacuum adsorption cutting fixture for brittle alloy pipes, including a mounting base 1, an elastic band 2 on one side of the mounting base 1, and hinge seats 3 fixedly connected to both ends of the elastic band 2. The hinge seats 3 are hinged to one end of the mounting base 1, and a rubber suction cup sleeve 4 is fixedly connected to the groove at one end of the hinge seat 3. A suction tube 5 is fixedly connected to one side of the rubber suction cup sleeve 4, and a pressure main tube 6 is fixedly connected between the two suction tubes 5.
[0016] At this point, it is worth noting that the mounting base 1 provides a basic installation and support platform for the entire clamp. The elastic band 2 has good elasticity and can adaptively stretch and adjust according to different pipe diameters, ensuring that the rubber suction cup sleeve 4 can fit tightly against the pipe surface. The hinged base 3 realizes the rotatable connection between the elastic band 2 and the mounting base 1, allowing the rubber suction cup sleeve 4 to flexibly adjust its angle on the mounting base 1 to better adapt to the outer contour shape of pipes of different diameters. The rubber suction cup sleeve 4 is a key component for realizing the vacuum adsorption function, and the suction pipe 5 connected to one side is connected to the pressure main pipe 6. When the pressure main pipe 6 is evacuated by external equipment, the air inside the rubber suction cup sleeve 4 is extracted, forming a negative pressure environment, thereby using atmospheric pressure to tightly adsorb the brittle alloy pipe onto the rubber suction cup sleeve 4. Compared with the traditional mechanical clamping method, this vacuum adsorption method can provide a more uniform force, avoid the problem of excessive local pressure on the pipe surface, and effectively reduce the risk of indentation, cracking, and breakage on the pipe surface.
[0017] like Figure 4 As shown, one end of the mounting base 1 has an arc-shaped through structure.
[0018] At this point, it is worth noting that one end of the mounting base 1 has an arc-shaped through-type structure. This arc-shaped through-type structure can better adapt to the outer arc-shaped surface of the brittle alloy pipe. When the pipe is placed on the mounting base 1, the arc-shaped through-type structure can provide stable support for the pipe, reducing swaying and displacement during the cutting process. At the same time, the arc-shaped through-type structure can also guide the cutting debris to a specific direction to avoid the accumulation of debris around the clamp, which would affect the normal cutting operation and cause secondary damage to the pipe surface.
[0019] like Figure 4As shown, the mounting base 1 has two slots 11 with a symmetrical structure on the outside. One of the slots 11 is into which a debris collection box 12 is inserted. Two outer support plates 13 are hinged to one end of the debris collection box 12 with a symmetrical structure. An elastic rope 14 is fixed between the two outer support plates 13. One end of the outer support plate 13 is bent and is fixed to a lower frame 15.
[0020] At this point, it is worth noting that the symmetrical design of the slot 11 ensures that the debris collection box 12 can flexibly adjust the receiving position during the installation and use of the mounting base 1, effectively collecting the debris generated during the cutting of brittle alloy pipes. The symmetrical hinged design of the outer support plate 13 allows for flexible adjustment based on the pipe diameter and actual cutting conditions. When the pipe is placed on the clamp for cutting, the outer support plate 13 automatically conforms to the bottom of the pipe under the action of the elastic rope 14, providing additional support and preventing the pipe from sinking or shifting due to gravity or cutting force during the cutting process. The bent structure at one end of the outer support plate 13 better conforms to the outer contour of the pipe, increasing the contact area and improving the stability of the support. Simultaneously, the bent structure also acts as a limiting mechanism, preventing the pipe from rolling during cutting, further ensuring the accuracy and safety of the cutting operation. A lower frame 15 is fixedly connected to one side of the outer support plate 13. The main function of the lower frame 15 is to further optimize the discharge path of debris, improve the efficiency and effect of debris collection, and maintain the cleanliness and safety of the working environment.
[0021] like Figure 3 As shown, one end of the rubber suction cup sleeve 4 has an arc-shaped structure.
[0022] At this point, it is worth noting that one end of the rubber suction cup sleeve 4 has an arc-shaped structure. This design is intended to better match the outer arc-shaped surface of the brittle alloy pipe. The arc-shaped rubber suction cup sleeve 4 can form a larger contact area with the pipe surface during vacuum adsorption, thereby improving the stability and firmness of the adsorption. Compared with a flat suction cup, the arc-shaped rubber suction cup sleeve 4 can better adapt to the outer contour shape of pipes of different diameters. Regardless of the pipe diameter, it can ensure a tight fit, effectively avoiding insufficient adsorption force or air leakage caused by poor adhesion between the suction cup and the pipe surface. This ensures the reliability and effectiveness of the vacuum adsorption cutting fixture when cutting pipes of various diameters.
[0023] When working or using, first place the brittle alloy pipe to be cut at one end of the arc-shaped through structure of the mounting base 1. The position of the pipe should ensure that its central axis is consistent with the cutting direction of the cutting equipment. At this time, the brittle alloy pipe is laid down and the elastic band 2 is deformed. The deformed elastic band 2 drives the rubber suction cup sleeves 4 on the hinge seats 3 at both ends to come close to the surface of the pipe for adhesion and adsorption. Next, the external vacuum equipment (such as a vacuum pump) is connected to the pressure main pipe 6, and the vacuum equipment is started to evacuate the air inside the rubber suction cup sleeve 4. As air is gradually extracted, a negative pressure environment is formed inside the rubber suction cup sleeve 4. Under the action of atmospheric pressure, the pipe is tightly adsorbed onto the rubber suction cup sleeve 4. During the adsorption process, the flexible material of the rubber suction cup sleeve 4 can adaptively deform according to the slight irregularities on the surface of the pipe, ensuring that the entire adsorption process is uniform and stable, and avoiding local stress concentration on the surface of the pipe. During the cutting process, the debris generated by the cutting equipment falls into the debris collection box 12 for collection. It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
