Description

Technical Field

[0001] The utility model relates to the technical field of floating ring processing, in particular to a floating ring processing tool. Background Art

[0002] Floating rings are widely used in the real world, primarily as shaft seals in various rotating machinery, such as pumps, compressors, and agitators. They effectively prevent liquid or gas leakage, ensuring safe and efficient operation. They offer a simple structure, stable sealing performance, and high-temperature and corrosion resistance, making them suitable for high-speed rotation and high-pressure environments. They are widely used in industries such as petrochemicals, power generation, food and pharmaceuticals, automotive manufacturing, and construction machinery to improve equipment reliability and ease maintenance.

[0003] Floating rings are primarily made of magnesium alloy, which boasts lightweight, high specific strength, and excellent electrical and thermal conductivity. This makes it particularly well-suited for use in the manufacture of floating rings, particularly in the aerospace industry, where its properties can significantly reduce weight. However, its exceptionally soft material makes the parts susceptible to deformation and corrosion. To prevent deformation, conventional techniques involve turning a mandrel to position the part on the end face, then affixing it to the mandrel with 502 glue. After processing, the part is then soaked in acetone to release it from the mandrel. Furthermore, since magnesium alloys naturally oxidize and corrode after exposure to air, the time between processing and electroplating is limited to three to four days. Furthermore, each soaking and removal process can only accommodate four to six parts, with a maximum of two per day. The second soaking and removal process takes place the following day, and in winter, an electric heater must be used to bake the parts. Consequently, processing 20 parts requires approximately two and a half days, plus inspection and reprocessing, adding up to a total of three days. This significantly reduces processing efficiency, significantly impacting production schedules and presenting a pressing challenge in the field of floating ring processing technology. Utility Model Content

[0004] The purpose of the utility model is to provide a floating ring processing tool, which changes the part clamping method, uses a locking component to fix the core shaft and the floating ring to be processed, and uses a nut cover to fix the floating ring for easy processing. While ensuring the stability of the floating ring, it helps to improve processing efficiency and accuracy.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The utility model discloses a kind of floating ring outer ring surface and non-reference surface processing tool, including mandrel and first floating ring blank, the first floating ring blank is annular structure, and the side end face of first floating ring blank has been completed processing and as reference surface of tool installation;The through hole is pre-symmetrical and opened in the first floating ring blank along ring surface, the mandrel is opened with stop opening step along outer circumferential side edge on the end face for installing first floating ring blank, the step plane of stop opening step is used to abut with the reference surface of first floating ring blank, the step vertical surface of stop opening step is used to abut with the inner ring surface of first floating ring blank;

[0007] Locking component includes press bar and bolt, the press bar both ends from the inner ring surface side of first floating ring blank into the through hole being symmetrically opened, strip hole is provided on the press bar, the mandrel is provided with threaded hole towards the end face center of first floating ring blank, the bolt is inserted into strip hole and is screwed with the threaded hole, by bolt head to press bar towards mandrel direction extrusion force is applied, and then by press bar first floating ring blank is locked with mandrel.

[0008] The utility model when carrying out floating ring outer ring surface and non-reference surface processing, the working principle of its processing tool is as follows: first floating ring blank is positioned using stop opening step, first floating ring blank reference surface and the step plane of stop opening step are closely combined, first floating ring blank is pressed tightly with mandrel using locking component, the both ends of press bar are inserted into floating ring using the through hole pre-set on first floating ring blank, and after adjusting press bar position so that the both ends of press bar meet with the contact part of first floating ring blank, by bolt is inserted into strip hole, and the extrusion force is applied to press bar by screwing bolt head, and then press bar is pressed tightly with mandrel, realize the fixation between first floating ring blank and mandrel, after first floating ring blank and mandrel are fixed, mandrel can be fixed and installed on processing lathe as fixed clamping part, and the outer ring surface and non-reference surface of first floating ring blank are further finished.

[0009] In this way, locking component can provide uniform and sufficient locking force for mandrel and first floating ring blank, prevent displacement of first floating ring blank during machining due to turning, and improve machining precision. Meanwhile, the larger contact area is provided by the waist-shaped structure of strip hole, and the waist-shaped structure of strip hole and threaded hole is used in cooperation, when bolt passes through strip hole and threaded hole, greater friction and locking force can be provided, the stability of the whole clamping structure is improved, the risk of loosening due to vibration or cutting force during machining is reduced.

[0010] Preferably, it further includes gasket arranged between bolt and press bar.

[0011] In this way, since the pressure rod is made of wood and its hardness and rigidity are relatively weak, the gasket can be used to disperse the pressure of the bolt on the pressure rod, preventing the surface of the pressure rod from being deformed or damaged due to excessive force. At the same time, the gasket can protect the contact surface between the pressure rod and the bolt.

[0012] Preferably, the center line of the strip-shaped hole is positioned at the midpoint of the length of the pressure rod.

[0013] In this way, when the bolt passing through the strip hole rotates downward to apply pressure, the midpoint positioning helps to make the forces at both ends of the pressure rod symmetrical, so that the first floating ring blank is subjected to uniform pressure, avoiding deformation of the first floating ring blank due to uneven force.

[0014] Preferably, the length of the pressure rod is greater than the inner diameter of the first floating ring blank and smaller than the outer diameter of the first floating ring blank, and a first cylindrical pin and a second cylindrical pin are respectively provided at both ends of the pressure rod. The length of the first cylindrical pin is greater than the length of the second cylindrical pin, and the length distance from the end face of the second cylindrical pin away from the first cylindrical pin to the end face of the first cylindrical pin close to the second cylindrical pin is greater than the inner diameter of the first floating ring blank.

[0015] In this way, it is ensured that the pressure rod will not fall out of the first floating ring blank when tilted or subjected to external force. At the same time, by setting cylindrical pins of different lengths, it is more convenient to assemble and disassemble the pressure rod. When assembling the pressure rod, the longer first cylindrical pin must be inserted into the through hole first, and then the shorter second cylindrical pin must be inserted into the corresponding through hole to realize the assembly of the pressure rod. If the shorter second cylindrical pin is assembled first, it may interfere with or hinder the correct positioning of the first cylindrical pin when trying to assemble it. Assembling the longer first cylindrical pin first can avoid this situation.

[0016] Preferably, the pressure rod is made of wood.

[0017] Like this, because wood material its hardness and rigidity are weaker, it is helpful to assemble the compression rod.

[0018] The present invention also proposes a tool for processing the inner ring surface of a floating ring, which includes a core shaft, a second floating ring blank and a nut cover. One side end face and the outer cylindrical side wall of the second floating ring blank have been processed. The processed side end face serves as a reference surface for tool installation, and the end face away from the reference surface serves as a non-reference surface for tool installation; the nut cover is sleeved on the second floating ring blank, and the second floating ring blank is mounted on the core shaft through a stop step. The core shaft has an external thread corresponding to the nut cover installation position section, and the nut cover connecting section is provided with an internal thread matching the external thread. The core shaft and the nut cover are threadedly matched through the external thread and the internal thread to provide a locking force.

[0019] When the inner ring surface of the floating ring is processed by the present invention, the working principle of the processing tooling is as follows: when the inner ring of the second floating ring blank is processed, the second floating ring blank and the core shaft are still kept in a fixed state by the locking component; when the inner ring of the second floating ring blank is processed, a nut cover is added; the nut cover and the core shaft are matched through threads; the core shaft is selected to press the non-reference surface of the second floating ring blank; after the second floating ring blank is pressed, the locking bolts, gaskets and pressure strips are removed in sequence; at this time, the core shaft can be fixedly installed on the processing lathe as a fixed clamping part to further fine-process the inner ring surface of the second floating ring blank.

[0020] In this way, the locking component is used to maintain the fixed state of the second floating ring blank and the core shaft, and the axial position of the second floating ring blank can be accurately controlled by screwing the nut cover and the core shaft, ensuring the accuracy and repeatability of the processing. After removing the locking component, the inner ring surface can be directly processed, which improves work efficiency.

[0021] Preferably, the nut gland has an opening on the side facing the core shaft that matches the inner ring surface size of the second floating ring blank, and the inner diameter of the nut gland away from the core shaft is larger than the inner diameter of the second floating ring blank and smaller than the outer diameter of the second floating ring blank.

[0022] In this way, a tight fit between the nut cover and the second floating ring blank is ensured, stable support is provided, and displacement of the second floating ring blank is prevented during processing; the inner diameter design on the side away from the core shaft allows the nut cover to be easily put on the second floating ring blank, ensuring that it will not slip, and facilitating the removal of the locking parts, thereby facilitating the processing of the inner ring surface of the second floating ring blank.

[0023] Preferably, the nut cover connecting section is provided with a notch along the inner peripheral side of the nut cover away from the core shaft, and the notch is used to accommodate the second floating ring blank to prevent the cutting angle between the ring surface and the non-reference surface of the second floating ring blank from being damaged during the processing of the second floating ring blank.

[0024] In this way, due to the wear of the cutting tool, the corner of the nut cover obtained by cutting may not be a right angle, but may have an arc. When the nut cover is screwed onto the core shaft, there is wear between the non-reference surface of the second floating ring blank and the corner with the arc, resulting in the problem that the non-reference surface of the inner ring surface is worn after processing. This embodiment can solve this problem through the notched end face, reducing the direct pressure on the cutting angle of the reference surface of the second floating ring blank, thereby protecting the integrity of the second floating ring blank during the processing and ensuring the processing quality.

[0025] Preferably, the diameter of the notch end surface is larger than the outer diameter of the second floating ring blank.

[0026] In this way, there is enough gap for assembly and disassembly, and the larger diameter can reduce wear and damage to the second floating ring blank.

[0027] The technical scheme of the utility model has the following beneficial effects:

[0028] (1) When the outer ring surface and the non-reference surface of the floating ring are machined, the locking component is used to press the floating ring blank and the mandrel, the pressure rod is inserted into the floating ring through the pre-set through hole on the floating ring blank, and the bolt is sequentially threaded through the strip-shaped hole and the threaded hole, and the bolt head is screwed down to press the pressure rod and the mandrel, so that the floating ring blank and the mandrel are fixed, and the outer ring surface and the non-reference surface of the floating ring blank can be machined after the floating ring blank and the mandrel are fixed. The locking component can provide uniform and sufficient locking force for the mandrel and the floating ring blank, prevent the floating ring blank from moving due to turning during machining, and improve the machining precision.

[0029] (2) When the inner ring surface of the floating ring is machined, the floating ring blank and the mandrel are still in a fixed state through the locking component, and the nut pressure cover is additionally arranged when the inner ring of the floating ring blank is machined. The nut pressure cover and the mandrel are screwed through thread cooperation, the locking component is removed at this time, and the machining operation of the inner ring of the floating ring blank is convenient; the nut pressure cover and the mandrel are screwed through thread cooperation, the locking component is removed at this time, and the machining operation of the inner ring of the floating ring blank is convenient. The utility model provides axial support for the floating ring blank by thread cooperation between the nut pressure cover and the mandrel, so that axial movement of the floating ring blank during turning is prevented, and the machining precision is improved.

[0030] (3) The locking component and the nut pressure cover are used to realize quick clamping and releasing of the floating ring blank machining tooling, greatly improving the convenience and production efficiency of operation. Such design simplifies the clamping process, shortens the machining cycle, and ensures the machining precision and stability. BRIEF DESCRIPTION OF DRAWINGS

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0043] like Figures 1 to 5 As shown, a tool for processing the outer annular surface and non-reference surface of a floating ring includes a core shaft 1 and a first floating ring blank 6. The first floating ring blank 6 is annular, and one end surface of the first floating ring blank 6 has been processed and serves as a reference surface for tool installation. The first floating ring blank 6 is pre-symmetrically provided with through holes along the annular surface. The end surface of the core shaft 1 for mounting the first floating ring blank 6 is provided with a stop step 2 along the outer peripheral side. The step plane of the stop step 2 is used to abut the reference surface of the first floating ring blank 6, and the step vertical surface of the stop step 2 is used to abut the inner annular surface of the first floating ring blank 6.

[0044] The locking component includes a pressure rod 3 and a bolt 4. Both ends of the pressure rod 3 extend from one side of the inner ring surface of the first floating ring blank 6 into the symmetrically opened through-hole. A strip hole 31 is provided on the pressure rod 3. A threaded hole is provided at the center of the end face of the core shaft 1 facing the first floating ring blank 6. The bolt 4 extends into the strip hole 31 and is threadedly engaged with the threaded hole. The head of the bolt 4 applies an extrusion force toward the core shaft 1 to the pressure rod 3, and then the first floating ring blank 6 and the core shaft 1 are locked through the pressure rod 3.

[0045] like Figure 5 This is an example diagram of the tooling for processing the outer ring surface and non-reference surface of the floating ring of the utility model. The working principle of the tooling is: the first floating ring blank 6 is positioned by using the stop step 2, and the reference surface of the first floating ring blank 6 is tightly fitted with the end surface of the stop step 2. The first floating ring blank 6 and the core shaft 1 are pressed together by using the locking component. The two ends of the pressure rod 3 are inserted into the floating ring by using the preset through holes on the first floating ring blank 6, and the position of the pressure rod 3 is adjusted so that the two ends of the pressure rod 3 and the contact parts of the first floating ring blank 6 roughly meet. After that, the bolt 4 is inserted into the strip hole 31 and the head of the bolt 4 is turned to apply an extrusion force to the pressure rod 3, thereby pressing the pressure rod 3 and the core shaft 1 to achieve the fixation between the first floating ring blank 6 and the core shaft 1. After the first floating ring blank 6 and the core shaft 1 are fixed, the outer ring surface and non-reference surface of the first floating ring blank 6 can be further fine-machined by fixing the core shaft 1 as a fixed clamping part on the processing lathe.

[0046] In this way, the locking component can provide uniform and sufficient locking force for the core shaft 1 and the first floating ring blank 6, preventing the first floating ring blank 6 from being displaced due to turning during the machining process, thereby improving the machining accuracy.

[0047] In a specific application embodiment, the bolt 4 can be a hexagon socket bolt 4, and the size of the stop step 2 is matched with the size of one side of the inner ring surface of the first floating ring blank 6 to ensure that the fitting clearance is less than 0.01mm, and the stop step 2 and the end face are processed and formed at one time, and the parallelism of the two end faces of the processed reference surface and the non-reference surface is less than 0.02mm.

[0048] In this embodiment, a gasket is further included between the bolt 4 and the pressure rod 3 .

[0049] In this way, since the pressure rod 3 is made of wood and its hardness and rigidity are relatively weak, the gasket can be used to disperse the pressure of the bolt 4 on the pressure rod 3, preventing the surface of the pressure rod 3 from being deformed or damaged due to excessive force. At the same time, the gasket can protect the contact surface between the pressure rod 3 and the bolt 4.

[0050] In this embodiment, the center line of the strip-shaped hole 31 is located at the midpoint of the length of the pressure rod 3 .

[0051] In this way, when the bolt 4 passing through the strip hole 31 rotates downward to apply pressure, the midpoint positioning helps to make the forces at both ends of the pressure rod 3 symmetrical, so that the first floating ring blank 6 is subjected to uniform pressure, avoiding deformation of the first floating ring blank 6 due to uneven force.

[0052] In the embodiment, the strip-shaped hole 31 is of a waist-shaped structure, the mandrel 1 is provided with a threaded hole in the center of the end face of the first floating ring blank 6, the bolt 4 is sequentially inserted into the strip-shaped hole 31 and the threaded hole, and the head of the bolt 4 is rotated to lock the pressing rod 3 and the mandrel 1.

[0053] In this way, the strip-shaped hole of the waist-shaped structure provides a larger contact area, and the strip-shaped hole 31 and the threaded hole of the waist-shaped structure are used in cooperation, which can provide greater friction and locking force when the bolt 4 passes through the strip-shaped hole 31 and the threaded hole, improves the stability of the entire clamping structure, ensures that the pressing rod 3 is stably fixed on the mandrel 1, and reduces the risk of loosening due to vibration or cutting force during processing.

[0054] In the embodiment, the length of the pressing rod 3 is greater than the inner diameter of the first floating ring blank 6 and less than the outer diameter of the first floating ring blank 6, and the first cylindrical pin 32 and the second cylindrical pin 33 are respectively arranged at both ends of the pressing rod 3, the length of the first cylindrical pin 32 is greater than the length of the second cylindrical pin 33, and the length distance from the end face of the second cylindrical pin 33 away from the first cylindrical pin 32 to the end face of the first cylindrical pin 32 close to the second cylindrical pin 33 is greater than the inner diameter of the first floating ring blank 6.

[0055] In this way, it is ensured that the pressing rod 3 will not be pulled out of the first floating ring blank 6 when it is inclined or subjected to external force, and at the same time, by arranging cylindrical pins of different lengths, it is more convenient to assemble and disassemble the pressing rod 3, when assembling the pressing rod 3, the longer first cylindrical pin 32 is first inserted into the through hole, and then the shorter second cylindrical pin 33 is inserted into the through hole to realize the assembly of the pressing rod 3, if the shorter second cylindrical pin 33 is assembled first, it may interfere or hinder the correct positioning of the first cylindrical pin 32 when trying to assemble the first cylindrical pin 32, and assembling the longer first cylindrical pin 32 first can avoid this situation.

[0056] In the embodiment, the pressing rod 3 is made of wood.

[0057] In this way, since the wood material has weak hardness and rigidity, it is helpful for the assembly of the pressing rod 3.

[0058] As Figures 6 to 8As shown, the utility model also proposes a floating ring inner ring surface processing tool, including a core shaft, a second floating ring blank 6 and a nut cover 5, one side end face and the outer cylindrical side wall of the second floating ring blank 6 have been processed, and the processed side end face is used as a reference surface for tool installation, and the end face away from the reference surface is used as a non-reference surface for tool installation; the nut cover 5 is sleeved on the second floating ring blank 6, and the second floating ring blank 6 is clamped and installed on the core shaft 1 through the stop step 2, and the core shaft 1 has an external thread corresponding to the installation position section of the nut cover 5, and the nut cover 5 connecting section is provided with an internal thread matching the external thread, and the core shaft 1 and the nut cover 5 are threadedly matched through the external thread and the internal thread to provide locking force.

[0059] The second floating ring blank 6 can be the first floating ring blank that has been finely machined on the reference surface and the outer circumferential sidewall, and then can be used as the second floating ring blank 6 , and is further prepared for fine machining of the inner ring surface.

[0060] like Figure 8 The figure shows an example of the tooling for processing the inner ring surface of the floating ring of the present invention. The working principle of the tooling is as follows: when processing the inner ring of the second floating ring blank 6, the second floating ring blank 6 and the core shaft 1 are still fixed by the locking component. When processing the inner ring of the second floating ring blank 6, a nut cover 5 is added. The nut cover 5 and the core shaft 1 are threaded together, and the core shaft 1 is selected to press the non-reference surface of the second floating ring blank 6. After the second floating ring blank 6 is pressed, the locking bolt 4, gasket and pressure strip are removed in sequence. At this time, the core shaft 1 can be fixedly installed on the processing lathe as a fixed clamping part to further fine-process the inner ring surface of the second floating ring blank 6.

[0061] In this way, the locking component is used to maintain the fixed state of the second floating ring blank 6 and the core shaft 1, and the axial position of the second floating ring blank 6 can be accurately controlled by screwing the nut cover 5 and the core shaft 1, thereby ensuring the accuracy and repeatability of the processing. After removing the locking component, the core shaft 1 can be fixedly installed on the processing lathe as a fixed clamping part, and further finishing of the inner ring surface can be directly performed, thereby improving work efficiency.

[0062] In specific application implementation, the roundness of the inner control outer circle of the processed floating ring is less than 0.02mm, the coaxiality of the outer circle on one side of the inner ring surface is less than 0.016mm, and in order to completely turn out the inner ring surface of the second floating ring blank 6, the end face of the tooling core shaft 1 can be turned off by 0..05~0.1mm.

[0063] In this embodiment, the nut cover 5 has an opening on the side facing the core shaft 1 that is adapted to the inner ring surface size of the second floating ring blank 6, and the inner diameter of the nut cover 5 on the side facing away from the core shaft 1 is larger than the inner diameter of the second floating ring blank 6 and smaller than the outer diameter of the second floating ring blank 6.

[0064] In this way, a tight fit between the nut cover 5 and the second floating ring blank 6 is ensured, stable support is provided, and the second floating ring blank 6 is prevented from being displaced during processing; the inner diameter design of the side away from the core shaft 1 allows the nut cover 5 to be easily put on the second floating ring blank 6, ensuring that it will not slip, and facilitating the removal of the locking parts, thereby facilitating the processing of the inner ring surface of the second floating ring blank 6.

[0065] In this embodiment, a notch 51 is provided along the inner circumferential side of the nut cover 5 at the connecting section away from the core shaft 1, and the notch 51 is used to accommodate the second floating ring blank 6 to prevent the cutting angle between the ring surface and the non-reference surface of the second floating ring blank 6 from being damaged during the processing of the second floating ring blank 6.

[0066] In this way, due to the wear of the cutting tool, the corner of the nut cover 5 obtained by cutting may not be a right angle, but may have an arc. When the nut cover 5 is screwed onto the core shaft 1, there is wear between the non-reference surface of the second floating ring blank 6 and the corner with the arc, resulting in the problem that the non-reference surface of the inner ring surface is worn after processing. This embodiment can solve this problem through the end face of the notch 51, reducing the direct pressure on the cutting angle of the reference surface of the second floating ring blank 6, thereby protecting the integrity of the second floating ring blank 6 during the processing and ensuring the processing quality.

[0067] In this embodiment, the end surface diameter of the notch 51 is larger than the outer diameter of the second floating ring blank 6 .

[0068] In this way, there can be enough clearance to facilitate assembly and disassembly, and the larger diameter can reduce wear and damage to the second floating ring blank 6.

[0069] The embodiment has the following technical effects: the embodiment realizes the fixing between the floating ring blank 6 and the mandrel 1 by pressing the floating ring blank 6 and the mandrel 1 by using the locking part when the outer ring surface and the non-reference surface of the floating ring are machined, by using the pre-set through hole on the floating ring blank 6 to make the two ends of the pressing rod 3 extend into the floating ring, and by making the bolt 4 pass through the strip-shaped hole 31 and the threaded hole in sequence, and by screwing the head of the bolt 4 to make it move downward to press the pressing rod 3 and the mandrel 1, after the floating ring blank 6 and the mandrel 1 are fixed, the outer ring surface and the non-reference surface of the floating ring blank 6 can be further machined by fixing and installing the mandrel 1 as a fixed clamping part on a machining lathe; the locking part can provide uniform and sufficient locking force for the mandrel 1 and the floating ring blank 6, prevent the floating ring blank 6 from moving due to turning in machining, and improve machining precision. After the machining of the outer ring surface and the non-reference surface is completed, when the inner ring surface of the floating ring needs to be machined, the floating ring blank 6 and the mandrel 1 are still in a fixed state by the locking part, the nut gland 5 is additionally arranged when the inner ring of the floating ring blank 6 is machined, the nut gland 5 and the mandrel 1 are screwed by thread cooperation, the locking part is removed at this time, and the machining operation of the inner ring of the floating ring blank 6 is convenient; the nut gland 5 and the mandrel 1 are screwed by thread cooperation between the nut gland 5 and the mandrel 1, the floating ring blank 6 is pressed by the nut gland 5 at the same time, axial support is provided for the floating ring blank 6, axial movement of the floating ring blank 6 is prevented during turning, and machining precision is improved.
