Description
Technical Field
[0001] This utility model relates to the field of hydraulic flange processing technology, and in particular to a protective device for preventing scratches on the sealing surface of hydraulic flanges. Background Technology
[0002] Hydraulic flanges are detachable components in hydraulic systems that connect pipes, valves, and other elements. Their core function is to achieve a sealed and secure hydraulic oil passage. They are typically made of metal discs with bolt holes. During use, two flanges are pressed together with bolts, and a seal is sandwiched in between to prevent oil leakage. They are characterized by easy disassembly and assembly and strong pressure resistance. They are widely used in high-pressure hydraulic equipment, such as hydraulic systems of construction machinery and machine tools, and are key connecting components to ensure the normal operation of hydraulic systems.
[0003] A search revealed that the document with publication number "CN217583565U" mentions that this utility model relates to the field of flange technology and proposes a hydraulic flange that facilitates the connection of two flange bodies through a single adjustment, thereby improving work efficiency. It includes a flange body and a mounting base. Two flange bodies are provided, with a transmission pipe welded to one end of each flange body facing away from the other. A sliding groove is provided on the mounting base, within which a connecting block is slidably connected. The top of the connecting block is connected to an adjusting block via a limiting plate. A first fixing plate and a second fixing plate are fixedly connected to the top of the mounting base. A rotating hole is provided on the first fixing plate, within which a rotating rod is rotatably connected. A knob is connected to the left end of the rotating rod, and the right end of the rotating rod is rotatably connected to the second fixing plate via a screw passing through the adjusting block. A first U-shaped ring is fitted on the flange body, with the tops of the two first U-shaped rings fixedly connected to the bottom ends of the connecting block and the mounting base, respectively. A second U-shaped plate is fitted on the transmission pipe, and the second U-shaped plate is fixedly connected to the first U-shaped plate.
[0004] However, after the hydraulic flange is processed and formed, the sealing surface is ground, but the outer wall needs to be manually checked for defects and then micro-processed to remove surface impurities and metal debris. However, since the internal sealing surface has already been ground, if metal debris or other impurities fall into the hydraulic flange, they can easily scratch the sealing surface. Furthermore, during the grinding process, the hydraulic flange will vibrate and collide with the internal support structure, causing damage to the sealing surface.
[0005] Therefore, we provide a protective device for the sealing surface of hydraulic flanges to prevent scratches and solve the above problems. Utility Model Content
[0006] To achieve the above objectives, this utility model provides the following technical solution: A protective device for preventing scratches on the sealing surface of a hydraulic flange during machining includes a machining support platform. A sealing surface protection component is provided on the upper side of the machining support platform. The sealing surface protection component includes a support steel platform installed on the upper side of the machining support platform. A shock-absorbing rubber pad is installed on the outer side of the support steel platform. A hydraulic flange body is provided on the outer side of the shock-absorbing rubber pad. Support auxiliary components are installed on the outer side of the machining support platform. The support auxiliary components include flange bolt hole support plates welded to the outer side of the machining support platform. A magnetic limiting post is installed in the middle of the upper side of each flange bolt hole support plate.
[0007] As a further description of the above technical solution: The supporting steel platform and the processing supporting platform are welded together. The supporting steel platform has a conical structure and is interlocked with the hydraulic flange body.
[0008] As a further description of the above technical solution: The shock-absorbing rubber pad and the supporting steel platform are connected by a sleeve. The shock-absorbing rubber pad is made of silicone. The shock-absorbing rubber pad and the supporting steel platform together form a shock-absorbing structure for the hydraulic flange body.
[0009] As a further description of the above technical solution: The top inner side of the shock-absorbing rubber pad is bonded to a top hoop, which has a disc-shaped structure.
[0010] As a further description of the above technical solution: An inflatable sealing ring is bonded to the outer top of the shock-absorbing rubber pad. A sealing air pump is connected to the outer pipe of the inflatable sealing ring. The inflatable sealing ring forms a compression sealing structure on the inner top of the hydraulic flange body.
[0011] As a further description of the above technical solution: The magnetic limiting post and the hydraulic flange body are connected by a slot, and the magnetic limiting post and the hydraulic flange body are connected by a magnetic connection.
[0012] As a further description of the above technical solution: Pressure sensing probes are provided on both the left and right ends of the upper side of the flange bolt hole support plate, and a pressure sensor is provided on the lower side of the flange bolt hole support plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes a sealing surface protection component. When needed, the shock-absorbing rubber pad is placed on the outside of the supporting steel platform, followed by the hydraulic flange body being placed on the outer surface of the shock-absorbing rubber pad. After the hydraulic flange body is placed over the shock-absorbing rubber pad, the sealing air pump is started, causing the air sealing ring to expand. This creates a tight fit between the top inner side of the hydraulic flange body, effectively preventing external impurities from entering the sealing area and avoiding metal processing debris from entering the inner side of the hydraulic flange body, which could damage the sealing surface or affect subsequent assembly accuracy. When the outer surface of the hydraulic flange body is ground, the vibration generated by the hydraulic flange body is effectively absorbed by the shock-absorbing rubber pad, reducing hard impacts on the hydraulic flange body, thereby protecting the sealing surface inside the hydraulic flange body.
[0014] 2. This utility model uses a support auxiliary component to fit the hydraulic flange body over the shock-absorbing rubber pad. The bolt holes on the outside of the hydraulic flange body will then fit over the magnetic limiting post, thereby achieving a rigid limiting effect on the hydraulic flange body. The magnetic design of the magnetic limiting post can effectively improve the longitudinal stability of the hydraulic flange body during the grinding process, preventing longitudinal slippage when grinding the side. The pressure sensing probe can monitor the pressure changes of the hydraulic flange body after it is installed on the flange bolt hole support plate in real time and feed the data back to the pressure sensor to avoid excessive or insufficient grinding pressure.

[0017] 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.
[0018] Please see Figure 1-4 As shown, this utility model provides a technical solution: a sealing surface anti-scratch protection device for hydraulic flange processing, including a processing support platform 1, a sealing surface protection component 2 on the upper side of the processing support platform 1, the sealing surface protection component 2 including a support steel platform 201 installed on the upper side of the processing support platform 1, a shock-absorbing rubber pad 202 installed on the outer side of the support steel platform 201, a hydraulic flange body 206 installed on the outer side of the shock-absorbing rubber pad 202, and a support auxiliary component 3 installed on the outer side of the processing support platform 1, the support auxiliary component 3 including flange bolt hole support plates 301 welded to the outer side of the processing support platform 1, and a magnetic limiting post 302 installed in the middle of the upper side of the flange bolt hole support plate 301.
[0019] Furthermore, the support steel platform 201 is welded to the processing support platform 1. The support steel platform 201 has a conical structure and is interlocked with the hydraulic flange body 206. When needed, the hydraulic flange body 206 can be interlocked with the support steel platform 201, and fixed-point support can be achieved through their identical inner wall shape, which effectively improves the overall support stability.
[0020] Furthermore, the shock-absorbing pad 202 and the supporting steel platform 201 are connected by a sleeve. The shock-absorbing pad 202 is made of silicone. The shock-absorbing pad 202, together with the supporting steel platform 201, forms a shock-absorbing structure for the hydraulic flange body 206. When needed, the shock-absorbing pad 202 is sleeved on the outside of the supporting steel platform 201. At this time, the hydraulic flange body 206 is sleeved on the outer surface of the shock-absorbing pad 202 on the outside of the supporting steel platform 201. When the outer surface of the hydraulic flange body 206 is ground, the vibration generated by the hydraulic flange body 206 will be effectively absorbed by the shock-absorbing pad 202, and the hard impact of the hydraulic flange body 206 will be reduced, thereby protecting the sealing surface inside the hydraulic flange body 206.
[0021] Furthermore, a top clamp 203 is bonded to the inner side of the top of the shock-absorbing pad 202. The top clamp 203 has a disc-shaped structure. When needed, as the hydraulic flange body 206 is fitted over the shock-absorbing pad 202, the top clamp 203 on the inner side of the top of the shock-absorbing pad 202 can provide a stable support platform for the inflatable sealing ring 204. The top clamp 203 also seals the top of the shock-absorbing pad 202 and the supporting steel platform 201 to prevent processing debris from leaking in.
[0022] Furthermore, an inflatable sealing ring 204 is bonded to the outer top of the shock-absorbing pad 202. A sealing air pump 205 is connected to the outer side of the inflatable sealing ring 204. The inflatable sealing ring 204 forms a compression seal structure on the inner top of the hydraulic flange body 206. When needed, the hydraulic flange body 206 is fitted over the shock-absorbing pad 202, and the sealing air pump 205 is started to inflate the inflatable sealing ring 204, thereby forming a tight fit on the inner top of the hydraulic flange body 206. This effectively prevents external impurities from entering the sealing area and avoids metal processing debris from entering the inner side of the hydraulic flange body 206, which could damage the sealing surface or affect the subsequent assembly accuracy.
[0023] Furthermore, the magnetic limiting post 302 and the hydraulic flange body 206 are connected by a slot, and the magnetic limiting post 302 and the hydraulic flange body 206 are connected by a magnetic connection. When needed, after the hydraulic flange body 206 is put on the shock-absorbing pad 202, the bolt holes on the outside of the hydraulic flange body 206 will fit onto the magnetic limiting post 302, thereby achieving the function of rigidly limiting the hydraulic flange body 206. The magnetic design of the magnetic limiting post 302 can effectively improve the longitudinal stability of the hydraulic flange body 206 during the grinding process and avoid longitudinal slippage when grinding the side.
[0024] Furthermore, pressure sensing probes 303 are provided on both the upper left and right ends of the flange bolt hole support plate 301, and a pressure sensor 304 is provided on the lower side of the flange bolt hole support plate 301. When needed, the pressure sensing probes 303 can monitor the pressure changes of the hydraulic flange body 206 after it is installed on the flange bolt hole support plate 301 in real time, and feed the data back to the pressure sensor 304 to avoid excessive or insufficient grinding pressure.
[0025] Working principle: When needed, the processing support table 1 is fixed to the testing table. Then, the shock-absorbing rubber pad 202, along with the inflatable sealing ring 204, is fitted onto the support steel platform 201 on the processing support table 1. The top clamp 203 of the rubber pad is then embedded into the top of the shock-absorbing rubber pad 202 to provide support for the inflatable sealing ring 204. After preparation, the hydraulic flange body 206 is placed over the outside of the shock-absorbing rubber pad 202, and the connecting bolt holes on the outside of the hydraulic flange body 206 are fitted onto the magnetic limiting posts 302 on the flange bolt hole support plate 301. Subsequently, the air pump 205 is controlled to inject air into the air sealing ring 204, which compresses and seals the top of the hydraulic flange body 206. Finally, the worker uses a handheld grinding device to grind the hydraulic flange body 206. During the grinding process, the pressure is captured in real time by the pressure sensing probe 303 and the data is transmitted through the pressure sensor 304 to adjust the grinding pressure in time and avoid over-grinding. This completes the process of using a hydraulic flange processing sealing surface anti-scratch protection device.
[0026] 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.
