DETAILED DESCRIPTION

[0042] A hydraulic motor spindle machining and polishing device provided by the present application is described in detail below in combination with the drawings and specific embodiments. It is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and other alternative ways can also be adopted by those skilled in the art for some known technologies; and the drawings are only used to more specifically describe the embodiments, and are not intended to specifically limit the present application.

[0043] As Figures 1 to 8As shown, the hydraulic motor spindle machining and polishing device provided by the embodiment of the present application comprises an external cylindrical grinding machine 1, the internal part of the external cylindrical grinding machine 1 is configured with a multi-axis servo drive motor rack 2, the output end of the multi-axis servo drive motor rack 2 is configured with a polishing grinding wheel rack 3, and the bottom of the polishing grinding wheel rack 3 is assembled with a first C-shaped processing mechanism 6.

[0044] The first C-shaped processing mechanism 6 comprises a first C-shaped cavity cover 62, the first C-shaped cavity cover 62 is fixedly connected with an open access cover 63 for real-time access of waste liquid at the position opposite to the bottom of the polishing grinding wheel rack 3, a secondary filter plate 66 is assembled at the intermediate position inside the first C-shaped cavity cover 62 to filter impurities in the waste liquid flowing from the open access cover 63, a first extraction pump 65 is fixedly installed on the side of the first C-shaped cavity cover 62 away from the open access cover 63 to extract the liquid filtered by the secondary filter plate 66 and directly spray the liquid to the two side walls of the polishing grinding wheel rack 3 after grinding.

[0045] The intermediate position inside the first C-shaped cavity cover 62 is provided with an expansion type reserved opening 67 at the positions on both sides of the secondary filter plate 66, a second C-shaped processing mechanism 11 is configured at the bottom of the first C-shaped cavity cover 62 and connected with the two expansion type reserved openings 67, a shunt mechanism 7 for waste liquid treatment is assembled at the position of the two connected ends, a first conveying hose 8 for pouring and cooling is arranged on one side of the shunt mechanism 7 and directed to the top of the polishing grinding wheel rack 3, and a second conveying hose 9 for cooling is arranged on the other side of the shunt mechanism 7 and directed to the rotating shaft end of the polishing grinding wheel rack 3.

[0046] To solve the problem of low utilization rate of cooling liquid and insufficient efficiency of the recovery system of the high-precision cylindrical grinder in machining the main shaft of the hydraulic motor, the above technical scheme is adopted to solve the problem. The above technical scheme mainly comprises a cylindrical grinder 1, a multi-axis servo drive motor rack 2, a polishing grinding wheel rack 3, a first C-shaped processing mechanism 6, a shunt mechanism 7, a first conveying hose 8, a second conveying hose 9, and a second C-shaped processing mechanism 11. The cylindrical grinder 1, the multi-axis servo drive motor rack 2, and the polishing grinding wheel rack 3 are conventional grinder structures for machining the main shaft of the hydraulic motor in the prior art. The cylindrical grinder 1 serves as a whole frame, which is used to fix various mechanism components on one hand and to isolate the machining end on the other hand. In addition to the multi-axis servo drive motor rack 2 and the polishing grinding wheel rack 3 structure, the inside of the cylindrical grinder 1 also contains a headstock and a tailstock commonly used in the prior art, which is used to clamp and drive the main shaft of the hydraulic motor to rotate, ensuring that the main shaft remains stable and accurately rotates during the grinding process. The multi-axis servo drive motor rack 2 is configured to realize multi-axis linkage through a servo control system, which can move in horizontal, vertical or inclined directions, thereby driving the polishing grinding wheel rack 3 to adhere to the outer contour of the main shaft for precise grinding. The polishing grinding wheel rack 3 is connected to the output end of the multi-axis servo drive motor rack 2 side end, and uses the high-speed motor inside to drive the grinding wheel shaft sleeve 151 at the grinding wheel end to rotate at high speed, thereby achieving the polishing operation of the main shaft. The first C-shaped processing mechanism 6 includes a first C-shaped cavity cover 62, which is similar to a C-shaped structure and is located at both ends of the C-shaped structure. One side is provided with an open access cover 63, and the other side is provided with a first extraction pump 65. The open access cover 63 on one side is opposite to the position at the bottom of the polishing grinding wheel rack 3, which can collect the waste liquid generated in real time during the operation of the polishing grinding wheel rack 3. The first extraction pump 65 on one side is used to extract the collected waste liquid again. The second filter plate 66 is assembled at the middle position inside the first C-shaped cavity cover 62, which is at the lowest position of the C-shaped structure. The waste liquid extracted by the first extraction pump 65 is filtered by multiple stages, which is different from the liquid collecting tank arranged at the bottom of the cylindrical grinder 1 in the prior art. The open access cover 63 matches the movement track of the polishing grinding wheel rack 3, which can effectively collect the cooling liquid and metal chips splashed from the surface of the grinding wheel during the grinding process, and can also reduce the space inside the cavity of the recovery end.

[0047] The second C-shaped processing mechanism 11 is also in C-shaped structure, at the bottom of the first C-shaped cavity cover 62, and in the straight downward view from the top, the second C-shaped processing mechanism 11 and the first C-shaped cavity cover 62 form a cross-shaped intersection state, which is different from the secondary utilization effect of spraying the liquid filtered by the secondary filter plate 66 to the two side walls of the grinding wheel frame 3 after grinding. The second C-shaped processing mechanism 11 is assembled with a flow separation mechanism 7 for waste liquid treatment, and one side of the flow separation mechanism 7 is provided with a first conveying hose 8 for pouring and cooling on the top of the grinding wheel frame 3, which can be poured on the top of the grinding wheel frame 3 after secondary cooling treatment, further improving the effect of cooling the grinding end. The other side of the flow separation mechanism 7 is provided with a second conveying hose 9 for cooling the rotating shaft end of the grinding wheel frame 3, which is different from directly pouring on the top of the grinding wheel frame 3. The liquid after the secondary cooling treatment flows into the rotating shaft end of the grinding wheel frame 3, realizing shaft cooling and reducing thermal deformation.

[0048] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 The side of the first C-shaped cavity cover 62 is fixedly installed with a support frame 61, which is assembled on the multi-axis servo drive motor frame 2 to carry the first C-shaped cavity cover 62 to follow the movement of the grinding wheel frame 3. The inside of the open access cover 63 is assembled with a primary filter plate 64, the second filter plate 66 is in U-shaped partition structure transversely crossing the lowest point of the inside of the first C-shaped cavity cover 62, and the U-shaped open end faces one side of the primary filter plate 64, and a bidirectional outward pushing heat dissipation mechanism 12 is movably arranged on one side of the U-shaped opening.

[0049] The support frame 61 is made of rigid material and is fixed on the side end guide rail of the multi-axis servo drive motor frame 2 by bolts or welding, so that the first C-shaped cavity cover 62 is kept synchronous displacement with the polishing grinding wheel frame 3, and the open access cover 63 is always aligned with the waste liquid splashing area at the bottom of the grinding wheel during the grinding process, so that dynamic recovery is realized, the positioning deviation of the traditional fixed liquid collecting tank is avoided, and the cooling liquid capturing efficiency is improved. The first filter plate 64 arranged in the open access cover 63 is used for preliminarily intercepting larger particle metal scraps and grinding impurities. The first filter plate 64 adopts a detachable mesh structure, which is convenient for regular cleaning or replacement. The second filter plate 66 is arranged at the lowest point position in the first C-shaped cavity cover 62 and has a U-shaped opening end facing the side of the first filter plate 64. The second filter plate 66 is composed of multiple layers of stainless steel screens, and the U-shaped design can effectively collect liquid and guide the flow to both sides, and also can intercept fine impurities. A bidirectional outward pushing heat dissipation mechanism 12 is movably arranged on one side of the U-shaped opening of the second filter plate 66, which is used for dredging the impurity accumulation on the surface of the second filter plate 66 in real time and promoting liquid heat dissipation. The bidirectional outward pushing heat dissipation mechanism 12 includes a cylindrical sleeve frame 121 made of heat-conducting material, and a partition plate 122 fixedly installed at the inner middle position of the cylindrical sleeve frame 121, which divides the cylindrical sleeve frame 121 into two independent cavities. The partition plate 122 not only provides structural support, but also allows the two cavities to operate independently to realize the bidirectional pushing function.

[0050] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 The inside of the cylindrical sleeve frame 121 is divided into two independent cavities by the partition plate 122, and a bidirectional servo rotating rod 123 is fixedly installed in each cavity. An electric control magnetic suction sleeve ring 124 is engaged on the bidirectional servo rotating rod 123. A groove is formed in each cavity of the partition plate 122 for the reciprocating sliding of the electric control magnetic suction sleeve ring 124. Four equally spaced outer expansion blades 125 are fixedly installed on the outer surface of the cylindrical sleeve frame 121. The outer edges of the outer expansion blades 125 are attached to the side wall of the second filter plate 66, and a guide sliding groove 126 is formed in each outer expansion blade 125. The magnetic suction disc wiper 127 is slidably installed between the outer expansion blades 125 on the outer sides of the cylindrical sleeve frame 121 through the guide sliding groove 126. The outer edges of the electric control magnetic suction sleeve ring 124 are respectively attracted to the two magnetic suction disc wipers 127 through magnetic attraction across the cylindrical sleeve frame 121.

[0051] The configured bidirectional servo rotating rod 123 is a bidirectional threaded rotating rod in the prior art, and the engaged electrically-controlled magnetic suction sleeve ring 124 is driven by the servo end to reciprocally slide in the chambers on both sides of the partition plate 122. The electrically-controlled magnetic suction sleeve ring 124 is a circular sleeve structure, and an electrically-controlled magnetic suction ring is arranged on the outer edge thereof to ensure the magnetic suction state. Four equidistantly arranged outer expansion fan blades 125 are fixedly installed on the outer surface of the cylindrical sleeve frame 121. The outer edge of each outer expansion fan blade 125 is attached to the sidewall of the secondary filter plate 66. In the process of rotation of the cylindrical sleeve frame 121, not only can the rotating force be used to drive the liquid entering the first C-shaped cavity cover 62 to flow more smoothly, but also the heat of the waste liquid can be dissipated through rotation, and the residual impurities on the secondary filter plate 66 can be scraped at the same time. A guide sliding groove 126 is formed in each outer expansion fan blade 125, and a magnetic disc wiper 127 clamped between the outer expansion fan blades 125 is slidably installed on the outer side of the cylindrical sleeve frame 121 through the guide sliding groove 126. In the working state, the two magnetic disc wipers 127 on the outer side of the cylindrical sleeve frame 121 are respectively attracted by the electrically-controlled magnetic suction sleeve ring 124 through the magnetic suction effect across the cylindrical sleeve frame 121. The reciprocating drive of the bidirectional servo rotating rod 123 enables the two magnetic disc wipers 127 on the outer side of the cylindrical sleeve frame 121 to reciprocally push from the midpoint of the cylindrical sleeve frame 121 to the two sides, so as to clean the impurities on the outer expansion fan blades 125 and guide the impurities to the expansion type reserved opening 67 on both sides of the secondary filter plate 66 to unblock the filtering state of the first C-shaped treatment mechanism 6.

[0052] Specifically, the waste liquid flows into the first C-shaped cavity cover 62 from the open access cover 63, and after being preliminarily filtered by the primary filter plate 64, enters the U-shaped groove opening on one side of the secondary filter plate 66. The fine impurities in the waste liquid are easily attached to the surface of the secondary filter plate 66, affecting the filtering efficiency. At this time, the bidirectional servo rotating rod 123 is driven to rotate. When the bidirectional servo rotating rod 123 in the left cavity rotates clockwise, the engaged electrically-controlled magnetic suction sleeve ring 124 slides to the left along the groove; at the same time, the bidirectional servo rotating rod 123 in the right cavity rotates counterclockwise, so that the right electrically-controlled magnetic suction sleeve ring 124 slides to the right. The synchronous reverse movement drives the magnetic disc wipers 127 on both sides to move along the guide sliding groove 126 to the two ends of the cylindrical sleeve frame 121 through the magnetic suction effect, so as to push and extrude the impurities accumulated on the U-shaped surface of the secondary filter plate 66 to the outside and guide them to the expansion type reserved openings 67 on both sides.

[0053] In the working process, the reciprocating motion of the magnetic disc scraper 127 is like a scraper, and each push can remove the impurities on the secondary filter plate 66 to prevent clogging. After the impurities are pushed into the expanded reserved opening 67, they flow into the second C-shaped treatment mechanism 11 for further treatment. The magnetic attraction force of the electric control magnetic attraction sleeve ring 124 can be controlled by adjusting the current intensity to ensure the adhesion of the scraper to the surface of the filter plate and avoid excessive wear. During the driving process, the rotation of the cylindrical sleeve frame 121 is caused by the interaction between the outward expanding fan blade 125 and the waste liquid flow, and the turbine effect of the outward expanding fan blade 125 accelerates the flow of waste liquid in the first C-shaped cavity cover 62, thereby enhancing heat exchange. At the same time, the heat-conducting materials of the cylindrical sleeve frame 121 and the outward expanding fan blade 125 conduct heat from the waste liquid to the surface of the mechanism for convective heat dissipation. After one push, the bidirectional servo rotating rod 123 rotates in the opposite direction to return the electric control magnetic attraction sleeve ring 124 and the magnetic disc scraper 127 to the initial position. The entire process can be controlled by conventional programming control of the existing technology PLC controller.

[0054] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 The second C-shaped treatment mechanism 11 includes a second C-shaped cavity cover 111, both sides of which are fixedly connected with horizontally arranged expansion pipes 112, which are respectively sealed to the expansion type reserved openings 67 on both sides of the first C-shaped cavity cover 62. The extension pipes 112 are fixedly connected with outwardly open conical cavities 117 at their extension ends, and the positions where the outwardly open conical cavities 117 and the expansion pipes 112 meet are connected with closed partitions. The bottom of the second C-shaped cavity cover 111 is fixedly connected with a conical cavity cylinder 113 at the middle position, the bottom of which is open and detachably sealed with a cover 114. A waterproof motor 115 is fixedly installed at the center position of the side of the conical cavity cylinder 113, and a reverse suction propeller blade 116 is fixedly installed on the output end of the waterproof motor 115. The expansion pipe 112 on one side of the second C-shaped cavity cover 111 is provided with a driving module 14.

[0055] The configured extension conduit 112 is made of corrosion-resistant metal pipe, and the interface is dynamically sealed by a rubber sealing ring to ensure that the waste liquid does not leak during transportation. The extension conduit 112 is fixedly connected with an outer open conical cavity 117 at the extension end. The closed partition plate at the joint of the conical cavity 117 and the extension conduit 112 is made of polytetrafluoroethylene material, which has sealing and wear resistance. The bottom of the conical cavity cylinder 113 is open and detachably sealed by a sealing cover 114. The sealing cover 114 is fixed by screw connection and is convenient for regular cleaning of deposited impurities. The waterproof motor 115 is an IP67 protection grade direct current servo motor, and the output end is fixedly installed with a back suction propeller blade 116. The back suction propeller blade 116 is made of stainless steel, and the blade is inclined. When the impurities enter the extension conduit 112 through the extension reserved opening 67, they are gathered to one side of the conical cavity cylinder 113 under the C-shaped cavity drainage effect of the second C-shaped cavity cover 111 and the vortex suction force of the back suction propeller blade 116. Due to the diffusion effect of the conical cavity, the fluid velocity decreases, and part of the heavier impurities preliminarily settle under the action of gravity. The arc structure of the cavity guides the fluid to flow along the wall, forming a centrifugal effect, so that the impurities further gather at the bottom of the cavity. The rotation of the back suction propeller blade 116 forms a downward suction force on one side, which accelerates the impurities to settle at the bottom of the conical cavity cylinder 113. On the other side, the rotating vortex separates the light impurities from the liquid, avoiding the re-entry of suspended matter into the circulating system. The deposited impurities finally fall into the bottom of the conical cavity cylinder 113, which can be cleaned by periodically dismounting the detachable sealing cover 114.

[0056] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The driving module 14 includes a servo motor 141. The output end of the servo motor 141 is sealed with a sealing cover connected with the outer open conical cavity 117 on the same side. A track sleeve 142 corresponding to the output end of the servo motor 141 is installed inside the sealing cover. A gear turntable 143 is installed on the track sleeve 142 and located at the center of the outer open conical cavity 117. First cooling fans 118 are movably installed inside the outer open conical cavity 117. Second cooling fans 146 are movably installed inside the extension conduit 112. The second cooling fans 146 on both sides of the second C-shaped cavity cover 111 are fixedly connected with the two sides of the cylindrical sleeve frame 121 to form an integral structure.

[0057] The configured driving module 14 is the core driving end of the device, and is arranged at the position of the one side end of the second C-shaped cavity cover 111. The first heat dissipation fan 118 and the second heat dissipation fan 146 on the second C-shaped cavity cover 111 are controlled to rotate by the driving of the side end. In the working state, the servo motor 141 drives the track cover 142 to rotate. The track cover 142 is engaged with the gear turntable 143 to rotate synchronously. The gear turntable 143 is connected with the first heat dissipation fan 118 on one side and the second heat dissipation fan 146 on the other side. Since the two second heat dissipation fans 146 on the two sides of the second C-shaped cavity cover 111 are integrated by the cylindrical sleeve frame 121, the second heat dissipation fan 146 on the other side will also rotate in the rotating state of the second heat dissipation fan 146 on the side of the servo motor 141, and the cylindrical sleeve frame 121 connected with the two second heat dissipation fans 146 will also rotate synchronously. The fan blades on the two second heat dissipation fans 146 on the two sides of the cylindrical sleeve frame 121 are oppositely inclined and arranged outward. In the rotating process, the inclined fan blades also increase the flowability of the liquid, so that the impurities on the two sides of the secondary filter plate 66 of the first C-shaped cavity cover 62 are better guided away.

[0058] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The second heat dissipation fan 146 on the side of the second C-shaped cavity cover 111 away from the servo motor 141 is fixedly connected with the first heat dissipation fan 118 penetrating the closed partition plate to form an integrated structure. The second heat dissipation fan 146 on the side of the second C-shaped cavity cover 111 close to the servo motor 141 is fixedly connected with the center of the gear turntable 143, and the gear turntable 143 is fixedly connected with the first heat dissipation fan 118 on the same side penetrating the closed partition plate to form an integrated structure. The conductor sleeve ring 144 is fixedly connected between the fan blades of the first heat dissipation fan 118, and a plurality of flexible heat dissipation fins 145 connected with the rotating rod end of the second heat dissipation fan 146 are fixedly connected on the conductor sleeve ring 144.

[0059] The outer open cone cavity 117 arranged on both sides of the second C-shaped cavity cover 111 is a separated cone cavity structure, and the cone design of the outer open cone cavity 117 can accelerate fluid diffusion and reduce flow resistance. The closed partition plate at the joint of the outer open cone cavity 117 and the expansion conduit 112 is made of polytetrafluoroethylene material. A conductor sleeve 144 is arranged on each first heat dissipation fan 118 in the outer open cone cavity 117. The conductor sleeve 144 is connected to each blade of the first heat dissipation fan 118, and the conductor sleeve 144 is connected to the rod end of the second heat dissipation fan 146 on the same side through a plurality of flexible heat dissipation fins 145.

[0060] The shaft of the second heat dissipation fan 146 is directly connected to the shaft of the first heat dissipation fan 118 through a rigid coupling. The closed partition plate is made of polytetrafluoroethylene or rubber sealing material to ensure dynamic sealing and prevent leakage of waste liquid. The integrated structure enables the second heat dissipation fan 146 and the first heat dissipation fan 118 to rotate synchronously and be controlled by an external driving source, i.e., a servo motor 141, to realize bidirectional heat dissipation. The conductor sleeve 144 is made of high-thermal-conductivity copper alloy, and the inner wall of the conductor sleeve 144 is fixed to the blade base through welding or bolts to quickly conduct the heat generated during fan operation. A plurality of flexible heat dissipation fins 145 are fixedly connected to the conductor sleeve 144. The heat dissipation fins 145 are made of thin-walled stainless steel memory alloy and have elastic deformation capability. When the second heat dissipation fan 146 rotates to contact liquid under external driving, the temperature of the internal liquid is transmitted to the conductor sleeve 144 through the heat dissipation fins 145, and then the heat is reduced through the rotating first heat dissipation fan 118 to accelerate heat dissipation.

[0061] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The second C-shaped processing mechanism 11 further includes an upper floating sleeve 119 fixedly installed at the top of each expansion conduit 112.

The upper side of the detachable rotary drum 71 is connected with a through granular storage cylinder 72. The top of the granular storage cylinder 72 is a threaded opening, and a second extraction pump 73 is rotatably installed through the threaded opening.

[0062] The configured shunt mechanism 7 is assembled on the floating sleeve 119 at the top of each side extension conduit 112, and the liquid enters the second C-shaped cavity cover 111 from the first C-shaped cavity cover 62. Under the rotation of the second cooling fan 146 and the suction of the anti-suction propeller blade 116, the debris is collected and precipitated. When the servo motor 141 stops working, the liquid will be static and will be filled into the inside of the floating sleeve 119. According to the different output ends of the first conveying hose 8 and the second conveying hose 9 on both sides of the shunt mechanism 7, different particles are stored in the particle storage cylinder 72 on the two sides of the detachable rotating cylinder 71. The particles stored in the particle storage cylinder 72 connected with the first conveying hose 8 store the adsorbed particles and active particles, so that the liquid on the side of the first conveying hose 8 is purified and active before output, so that it can better act on the top of the polishing wheel frame 3 after output. The particles stored in the particle storage cylinder 72 connected with the second conveying hose 9 store the conductor particles to further improve the cooling effect, so that it can better act on the end of the rotating shaft of the polishing wheel frame 3 after output, and ensure better cooling effect.

[0063] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown in the second C-shaped cavity cover 111, a first conveying hose 8 is fixedly installed on the second extraction pump 73 on one side, and a cooling liquid spraying pipe 5 is fixedly installed on the extension end of the first conveying hose 8.

The second extraction pump 73 is used as a power source, adopts a corrosion-resistant centrifugal pump structure, the inlet end is connected with the particle storage cylinder 72 of the shunt mechanism 7 through a pipeline, and the outlet end is sealingly connected with the first conveying hose 8 and the second conveying hose 9 through flanges. The first conveying hose 8 and the second conveying hose 9 are made of flexible high-pressure-resistant material, the length thereof is adjustable according to the moving range of the polishing grinding wheel frame 3, and the continuous supply of cooling liquid during grinding is ensured. When the second extraction pump 73 is started, the liquid purified and cooled in the second C-shaped treatment mechanism 11 is extracted, conveyed to the cooling liquid spray pipe 5 through the first conveying hose 8, and forms atomized or beam-shaped jet through the nozzle, and is directly sprayed to the grinding area to realize the dual functions of cooling and chip removal. The extending end of the configured second conveying hose 9 is fixedly installed with a detachable side cover 4, the detachable side cover 4 is made of light alloy, is fixed to the side shaft end of the polishing grinding wheel frame 3 through a bolt or buckle structure, and a sealing ring is arranged in the inside to ensure that there is no leakage at the connection position. The detachable design is convenient for regular maintenance or replacement, such as cleaning blockage or checking wear. The second conveying hose 9 is connected with the backflow module 15 in the polishing grinding wheel frame 3 through the interface of the detachable side cover 4, and guides the cooling liquid to the core area of the shaft.

[0065] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 The backflow module 15 includes a grinding wheel shaft sleeve 151 fixedly installed at the output end of the multi-shaft servo drive motor frame 2, the inside of the grinding wheel shaft sleeve 151 is hollow, and the side facing the detachable side cover 4 is open to access the second conveying hose 9, a plurality of circular grooves 154 are sequentially arranged on the surface of the grinding wheel shaft sleeve 151, a plurality of communication openings 156 are circumferentially and equidistantly arranged on each circular groove 154, a first heat-conducting circular ring 153 is fixedly installed at the position of each circular groove 154 in the inside of the grinding wheel shaft sleeve 151, and a second heat-conducting circular ring 155 is fixedly installed on the outer surface of the circular groove 154, and each second heat-conducting circular ring 155 is connected with the first heat-conducting circular ring 153 on the same side through the communication opening 156 on the circular groove 154 to form an integrated structure.

[0066] The configured backflow module 15 is a key part of the cooling liquid circulation system, and is used to realize shaft cooling and heat recovery. As shown in the description and Figure 8As shown, the inside of the grinding wheel rotating shaft sleeve 151 is hollow, and the side towards the detachable side cover 4 is open to access the second conveying hose 9. The grinding wheel rotating shaft sleeve 151 is made of copper alloy which is a high thermal conductivity material, and the first thermal conductivity circular ring 153 and the second thermal conductivity circular ring 155 are connected to form an integrated structure, forming an inner and outer multi-layer heat exchange path, when the cooling liquid flows through, the heat is quickly conducted and dissipated through the thermal conductivity circular ring. The spiral backflow conduit 152 is inserted into the inside of the grinding wheel rotating shaft sleeve 151 through the opening at the side end of the grinding wheel rotating shaft sleeve 151, and the spiral backflow conduit 152 adopts a spiral design, which increases the contact area and residence time of the cooling liquid with the heat conduction surface, and strengthens the heat exchange efficiency. The second conveying hose 9 is a double pipe structure accessing the first end and the second end of the spiral backflow conduit 152, forming a closed loop circuit.

[0067] The cooling liquid flows into the spiral backflow conduit 152 from the inlet end of the second conveying hose 9, circulates in the inside of the grinding wheel rotating shaft sleeve 151, and returns to the second conveying hose 9 from the outlet end, realizing continuous cooling. During work, the cooling liquid absorbs the grinding heat generated by the rotating shaft, conducts the heat to the second C-shaped cavity cover 111 through the first thermal conductivity circular ring 153 and the second thermal conductivity circular ring 155, and is cooled by the liquid inside, effectively reducing the temperature of the rotating shaft, preventing the precision from being reduced due to thermal expansion, and prolonging the service life of the components.

[0068] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the backflow module 15 further comprises a spiral backflow conduit 152 fixedly connected to the extending end of the second conveying hose 9, the spiral backflow conduit 152 is inserted into the inside of the grinding wheel rotating shaft sleeve 151 through the opening at the side end of the grinding wheel rotating shaft sleeve 151, and the outer wall of the spiral backflow conduit 152 is attached to the inner ring of the first thermal conductivity circular ring 153, the second conveying hose 9 is a double pipe structure accessing the first end and the second end of the spiral backflow conduit 152, the extraction end of the first extraction pump 65 is connected with two second extraction hoses 13 close to the secondary filter plate 66, and the output end of the first extraction pump 65 is fixedly installed with the shapeable spray head 10 located on both sides of the grinding wheel frame 3.

[0069] Among them, the shapeable spray head 10 can adjust the spray angle according to the shape of the grinding wheel, and assist in cooling the side wall of the grinding wheel.

[0070] The use method provided by the application is as follows:

[0071] The application is used, first, based on the multi-axis servo drive motor frame 2 drives the polishing wheel frame 3 to the hydraulic motor spindle for the cylindrical grinding, during which, the support frame 61 assembled in the side end of the multi-axis servo drive motor frame 2 carries the first C-shaped processing mechanism 6 synchronous movement, makes the open access cover 63 always aligns with the bottom area of the grinding wheel, and real-time receives the cooling liquid containing the debris splashed in the grinding process. The waste liquid is preliminarily filtered by the first filter plate 64 in the open access cover 63, intercepts the larger particle metal debris, and then the liquid flows into the first C-shaped cavity cover 62. The second filter plate 66 located at the lowest point is designed as a U-shaped partition structure, the opening of which faces the side of the first filter plate 64, for secondary filtering of fine impurities, in the process, the four outer expansion blades 125 outside the cylindrical sleeve frame 121 generate vortex with rotation, promote liquid flow and auxiliary cooling, at the same time, the bidirectional servo rotating rod 123 drives the electric control magnetic suction sleeve ring 124 to reciprocate along the groove, and the magnetic suction disc scraper 127 is driven to slide along the guide sliding groove 126 by the magnetic suction effect, so as to push the impurities attached to the surface of the second filter plate 66 outward, guide the second C-shaped processing mechanism 11 through the expanded reserved opening 67, thereby avoiding filter plate blockage and maintaining filtering efficiency.

[0072] Then, the liquid treated by the second filter plate 66 is partially pumped by the first pumping pump 65, directly sprayed to the two sides of the polishing wheel frame 3 through the shapeable spray head 10, to realize preliminary cooling and flushing, and the other part of the liquid flows into the second C-shaped processing mechanism 11 through the expanded reserved opening 67. Specifically, the liquid enters the second C-shaped cavity cover 111 through the expanded conduit 112, the anti-suction propeller blade 116 installed in the tapered cavity cylinder 113 at the bottom of the second C-shaped cavity cover 111 rotates under the drive of the waterproof motor 115, generates vortex suction force, and promotes the impurities to settle at the bottom. At the same time, the servo motor 141 of the driving module 14 engages the gear turntable 143 through the track sleeve 142, drives the second cooling fan 146 on the same side to rotate, and since the two second cooling fans 146 are connected as a whole through the cylindrical sleeve frame 121, the other second cooling fan 146 rotates synchronously, and the inclined design of the fan blades enhances the liquidity and cooling effect of the liquid. The rotation of the second cooling fan 146 is further transmitted to the first cooling fan 118 through the gear turntable 143, so that the first cooling fan 118 in the outer open tapered cavity 117 works synchronously, and the conductor sleeve ring 144 between the fan blades is connected with the rotating rod of the second cooling fan 146 through the flexible heat dissipation fin 145, so as to accelerate heat conduction and dissipation. Through centrifugal sedimentation and forced cooling, the temperature of the cooling liquid is reduced, the problem of temperature rise and low efficiency of the cooling liquid after single use is solved, and the cooling performance of the circulating liquid is improved.

[0073] Then, the liquid treated by cooling and precipitation is layered in the second C-shaped cavity cover 111, the lighter liquid floats into the floating sleeve 119 at the top of the expansion conduit 112, and is output by the shunt mechanism 7. The first extraction hose 74 at the bottom of the detachable drum 71 extends into the floating sleeve 119 to extract the liquid. The particle storage cylinder 72 is filled with different treatment media according to functional requirements, one side stores adsorption and active particles for purifying and restoring the activity of the cooling liquid, and the other side stores conductor particles to further improve the heat dissipation performance. The liquid is transported to the cooling liquid spray pipe 5 by the first delivery hose 8 after being pressurized by the second extraction pump 73, and is sprayed from the top of the grinding wheel frame 3 to enhance the cooling and lubrication of the grinding area. The return module 15 is connected to the side of the grinding wheel frame 3, and the spiral return conduit 152 is inserted into the inside of the wheel shaft sleeve 151, the outer wall of which is attached to the inner ring of the first heat-conducting ring 153. The cooling liquid absorbs the heat generated by the shaft grinding when flowing through the spiral return conduit 152, and the heat is conducted to the second heat-conducting ring 155 through the communication opening 156, and is diffused to the external environment, achieving efficient cooling of the shaft center and reducing the influence of thermal deformation on the machining accuracy. This shunt treatment realizes the multifunctional reuse of the cooling liquid, customized output for different cooling requirements, and improves the resource utilization rate.

[0074] Finally, the liquid that has completed the shaft cooling is returned to the second delivery hose 9 by the spiral return conduit 152, forming a closed loop return, and the waste liquid continuously generated during the grinding process is continuously collected by the open access cover 63, and the above-mentioned filtering, cooling and shunt process is repeated.

[0075] And the detachable sealing cover 114 at the bottom of the second C-shaped treatment mechanism 11 is opened regularly to clean the impurities deposited in the conical cavity cylinder 113. The threaded opening design at the top of the particle storage cylinder 72 facilitates the replacement of treatment media. The whole system realizes efficient recycling of the cooling liquid through the coordinated work of multi-stage filtration and shaft cooling, reducing the external cooling liquid supplement demand.
