Description

Technical Field

[0001] The present application relates to the technical field of integrated cutting and polishing devices for housings, and in particular to an integrated cutting and polishing device for reducer housings with a double-sided polishing function. Background Art

[0002] When the shell is processed by the integrated cutting and polishing device, in order to ensure the processing efficiency of the shell, the shell is usually polished immediately after cutting. For example, the Chinese patent with publication number CN117961562A in the related technology proposes an integrated cutting and polishing device for octagonal tubes, which has the advantage of using a clamping jaw, a polishing component and an auxiliary component to cut the octagonal tube according to the length of the finished octagonal tube. The first outer polishing belt and the inner polishing belt in the polishing component can polish the outer wall of one end of the octagonal tube, thereby removing the burrs generated at the end during cutting.

[0003] After the reducer housing is cast, it is usually necessary to cut, expand, and grind the two axial holes on the housing. The housing axial holes are usually processed on a cutting machine during cutting. The axial holes are first clamped and positioned, and then the position of the cutting tool is adjusted according to the center of the axial hole to perform circumferential cutting on the axial hole. After the axial hole cutting is completed, the staff needs to transport the reducer housing to the grinder for fixation, and then adjust the position of the grinding wheel according to the size of the cut axial hole, and finely grind the axial hole, thereby achieving the purpose of cutting, expanding, and finely grinding the axial hole of the reducer housing to ensure the processing accuracy of the two axial holes of the reducer housing.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: the two-sided cutting and two-sided grinding of the two axial holes of the reducer housing are carried out in steps. First, the operating steps of disassembling and assembling the fixture and the process of adjusting the reducer housing are relatively complicated, and high temperature will be generated when the axial holes are cut. It is difficult for the staff to turn it over and transport it, and it takes a period of cooling, which affects the efficiency of cutting and grinding the two axial holes on the reducer housing. Second, the reducer housing is clamped multiple times, which easily leads to deviations in the center reference of the cutting and grinding of the two axial holes, thereby affecting the dimensional accuracy of the two axial holes and resulting in a high scrap rate of the reducer housing. Summary of the Invention

[0005] In order to solve the problem that the two-sided cutting and two-sided grinding of the two axial holes of the reducer housing are carried out in steps, the operation steps of disassembling and assembling the fixture and the process of adjusting the reducer housing are relatively complicated, and high temperature will be generated when the axial holes are cut. It is difficult for the staff to turn it over and transport it, and it takes a period of cooling, which affects the efficiency of cutting and grinding the two axial holes on the reducer housing. This application provides a cutting and grinding integrated device for a reducer housing with a double-sided grinding function.

[0006] The present application provides a double-sided grinding device for a reducer housing, which adopts the following technical solutions: A cutting and grinding integrated device for a reducer housing with a double-sided grinding function comprises a cutting frame, a cutting knife for cutting two axial holes on the housing, a grinder for grinding the axial holes of the housing, a cooling assembly for cooling the housing, an adjusting assembly for adjusting the cutting knife and the grinder, and a rotating assembly for rotating and adjusting the housing; The cooling assembly includes a cooling pipe provided on the cutting frame, a first hose and a second hose connected to the cooling pipe, a cooling member for providing coolant to the cooling pipe, a control member for controlling the flow of coolant in the cooling pipe, a switching member for switching the first hose and the second hose on and off, and a detection member for detecting the shaft hole of the housing; The adjustment assembly includes a support plate movably mounted on the cutting frame, a connecting block movably mounted on the support plate, a rotating disk rotatably mounted on the connecting block, a translation member for driving the support plate to translate, a lifting member for driving the connecting block to lift, and a rotating member for driving the rotating disk to rotate; The rotating assembly includes a supporting disk rotatably arranged on the cutting frame, a movable gear rotatably arranged on the supporting disk, an angle member for adjusting the angle of the supporting disk, and a driving member for driving the movable gear to rotate.

[0007] By adopting the above technical solution, coolant is usually required to cool the shaft hole of the reducer housing during cutting and grinding. When the shaft hole is cut, emulsion is usually used for cooling in order to save the cost of coolant. When the shaft hole is grinded, oil-based liquid is usually used for cooling in order to ensure the smoothness of the shaft hole surface. Although emulsion and oil-based liquid are both coolants, their cost prices are different. Emulsion is cheap and suitable for rough cutting to save costs, while oil-based liquid is expensive and suitable for fine grinding to ensure processing quality and avoid scratches on the cutting surface when the coolant impacts. However, the traditional integrated cutting and grinding device is not convenient for adjusting the temperature according to the shaft hole cutting and grinding process and the shaft hole processing. The type and flow of coolant require the staff to switch the type of coolant when switching between cutting and grinding the shaft hole. The staff may easily forget to switch or choose the wrong coolant type during operation, which cannot effectively guarantee the cost of coolant and the smoothness of the shaft hole surface. When the reducer housing shaft hole is being processed, if the housing temperature is too high and the coolant flow is insufficient, the shaft hole will overheat and deform, and the tool will also be accelerated. It will not only affect the accuracy of the shaft hole processing but also shorten the service life of the tool. If the housing temperature is too low and the coolant flow is too high, it will cause vibration and chatter marks, which will interfere with the stability of the tool in shaft hole processing, and will cause waste of coolant, increasing environmental protection and processing costs. The adjusting assembly can translate and lift the cutter and the grinder and can also flip and adjust the cutter and the grinder so as to facilitate moving the cutter and the grinder into the shaft hole of the housing. When the shaft hole of the housing needs to be cut, the cutter can be fitted with the inner wall of the shaft hole. When the shaft hole of the housing needs to be polished, the grinder can be fitted with the inner wall of the shaft hole, thereby achieving the purpose of integrated cutting and polishing of the shaft hole of the housing. The rotating assembly can drive the housing to rotate, clamp and flip ninety degrees, and then when the housing rotates, the cutter and the grinder can be used to cut and polish the shaft hole on the housing, and the flip adjustment of the housing can be completed. Double-sided cutting and double-sided grinding of the two axial holes on the shell, the cooling component can spray emulsion and oil-based liquid when the shell shaft hole is cut and ground, and can cool the shell shaft hole, cutting tool and grinder, and when the cutting tool and grinder are switched, the emulsion and oil-based liquid can be automatically switched. When the shell shaft hole is cut, the emulsion can be sprayed for cooling, and when the shell shaft hole is ground, the oil-based liquid can be sprayed for cooling. At the same time, the flow rate of the emulsion and the oil-based liquid can be controlled according to the temperature during the cutting and grinding of the shell shaft hole, and the margin of the shell shaft hole cutting and grinding can be detected to ensure the stability of the double-sided cutting and grinding of the shell shaft hole.

When the shell shaft hole is cut, the emulsion in the emulsification chamber can be sprayed on the shell shaft hole and the cutting tool through the first hose and the cooling pipe in turn by the liquid pump, and the shell shaft hole and the cutting tool being cut can be cooled. When the shell shaft hole is polished, the oil-based liquid in the oil-based chamber can be sprayed on the shell shaft hole and the cutting tool through the second hose, the first hose and the cooling pipe in turn by the liquid pump, and the shell shaft hole and the grinder being polished can be cooled.

The first valve and the second valve can be opened and closed, and the first hose and the second hose can be opened and closed. When the shell shaft hole is cut, the first hose is in the open state and the second hose is in the closed state, so that the cooling pipe sprays the emulsion. When the shell shaft hole is grinded, the first hose is in the closed state and the second hose is in the open state, so that the cooling pipe sprays the oil-based liquid.

[0012] Optionally, the translation member includes a hydraulic rod fixed on the cutting frame, and the output end of the hydraulic rod is fixedly connected to the support plate.

The adjusting block can detect the temperature during cutting and grinding of the shell shaft hole. The adjusting block will expand due to high temperature, and the size of the expansion of the adjusting block can be controlled by the temperature. Therefore, the expansion and contraction of the adjusting block will change with the temperature during the processing of the shell shaft hole. The expansion and contraction of the adjusting block will drive the moving rod to move, and in turn drive the wedge block, the connecting rod and the water baffle to move up and down. The telescopic spring will be compressed, and the size of the fluid gap between the top of the water baffle and the inner wall of the cooling pipe can be adjusted through the range of movement of the water baffle.

The servo motor can drive the transmission gear, movable gear, intelligent push rod, movable clamp block, fixed clamp block and shell to rotate in turn, and cooperate with the lifting and switching of the cutting knife or grinder to cut and grind the shell shaft hole.

[0024] Optionally, the angle member includes a drive motor fixed to the cutting frame, and the drive motor is fixedly connected to the output end of the support plate.

[0025] By adopting the above technical solution, the angle part can flip the shell, and the driving motor can drive the support plate, driving part and shell to rotate ninety degrees in turn, and then the shell can be turned over to facilitate the cutting knife and grinder to perform double-sided cutting and double-sided grinding on the two axial holes on the shell.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The driving part can clamp and fix the shell to avoid the shell from shaking or offsetting during processing, and ensure the effect of cutting and grinding the shell shaft hole. The translation part can move the movable block, cutting knife and grinder to the shell shaft hole. The lifting part can drive the cutting knife and grinder to move upward, so that the cutting knife or grinder can fit the inner wall of the shell shaft hole. The rotating part can switch and adjust the position of the cutting knife and grinder. The shell shaft hole can be cut and ground with the lifting part. When the shell shaft hole needs to be cut, the cutting knife can be used to cut the shell shaft hole. When the shell shaft hole needs to be ground, the grinder can be used to cut the shell shaft hole. The angle part can rotate the shell ninety degrees. After the shaft hole cutting and grinding are completed, the housing can be automatically turned over to complete the cutting and grinding operations of the other shaft hole of the housing, thereby improving the working efficiency of the shaft hole cutting and grinding of the housing, realizing double-sided turning and double-sided grinding of the shaft hole of the housing, realizing the purpose of integrating the shaft hole cutting and grinding of the housing and realizing double-sided cutting and double-sided grinding of the shaft hole of the housing. After the shaft hole of the housing is cut, it can be immediately ground. At the same time, after one shaft hole of the housing is processed, the other shaft hole on the housing can be processed immediately. There is no need to disassemble, clamp, transport and re-position the shaft hole of the housing, which can reduce the steps of the housing processing, improve the efficiency of the housing processing, ensure the accuracy of the shaft hole processing of the housing, and reduce the scrap rate of the reducer housing. 2. The switching part can automatically switch between the emulsion and the oil-based liquid when the cutting tool and the grinder are switched. On the one hand, it can save the cost of using the coolant when cutting the housing shaft hole, and on the other hand, it can ensure the smoothness of the housing shaft hole when grinding. The two coolants can be automatically switched when the cutting tool and the grinder are switched. The cooling part can spray the emulsion to cool the housing shaft hole and the cutting tool when cutting the housing shaft hole, and spray the oil-based liquid to cool the housing shaft hole and the grinder when grinding the housing shaft hole, so as to avoid the housing shaft hole from being cut and ground during cutting and grinding. The control unit can detect the temperature of the shell shaft hole during cutting and grinding, and control the flow rate of the coolant according to the temperature of the shell shaft hole when the cutter and grinder are processing the shell shaft hole. This can avoid the deformation of the shell shaft hole caused by overheating due to insufficient coolant flow when the processing temperature of the shell shaft hole is too high, thereby ensuring the accuracy of the shaft hole processing. It can also avoid vibration and chattering caused by excessive coolant flow when the processing temperature of the shell shaft hole is too low, thereby preventing waste caused by excessive coolant spraying. 3. The detection part can determine how far the shell shaft hole is from the qualified size, and then control the rotation speed of the shell and the switching of the cutter and the grinder. At the same time, it can know how much the cutter has cut the shell and how much the grinder has grinded the shell, and know whether the shell shaft hole size meets the qualified standard. When the shell shaft hole is about to be cut or polished, the rotation speed of the shell can be appropriately reduced to avoid the phenomenon of over-grinding due to the inability to stop in time when the shell shaft hole is polished, thereby achieving the purpose of cutting and polishing the shell shaft hole.

Under other working conditions, high-temperature elastomers, high-temperature composite materials, high-temperature plastic polymers, ceramic-based composite materials, natural rubber, styrene-butadiene rubber, nitrile rubber and EPDM rubber can also be selected. Any material that can withstand changes within 50°C and can expand and contract within 50°C to 400°C is sufficient. The selected material has excellent high-temperature performance, mechanical strength, fatigue resistance and corrosion resistance, which can ensure that the adjustment block 34 can be used for a long time and ensure the adjustment block The service life of 34 is improved. The flow rate of the coolant is controlled by adjusting the size of the temperature expansion of the adjustment block 34 to ensure the control effect of the coolant output. The method of controlling the coolant flow rate according to the processing temperature of the shell 9 in the prior art is usually achieved by controlling the solenoid valve with a temperature sensor. However, the temperature sensor may not be able to work stably in harsh environments such as high temperature and dust, affecting the control effect of the solenoid valve. At the same time, when the shell 9 rotates at high speed, the temperature sensor and the detection liquid it fits will be disturbed, and then the size of the electric control of the coolant flow rate will affect the accuracy of the control. Compared with the temperature sensor and solenoid valve to control the coolant flow rate, the use of a mechanical linkage structure to control the coolant flow rate has the advantages of high reliability, fast response speed, no need for external energy, low cost and good environmental adaptability.

[0043] The implementation principle of the embodiment of the present application of a cutting and grinding integrated device for a reducer housing with a double-sided grinding function is as follows: (1) Place the shell 9 on the fixed clamp block 7. The shell 9 can be positioned by the four positioning blocks 8 to ensure that the center of the shaft hole of the shell 9 corresponds to the center of the support block 45. The smart push rod 10 can drive the movable clamp block 11 to move downward, and cooperate with the fixed clamp block 7 to clamp the shell 9 to prevent the shell 9 from shaking or offsetting during processing, thereby ensuring the effect of cutting and grinding the shaft hole of the shell 9; (2) The hydraulic rod 12 can sequentially drive the support plate 13, the support block 45, the electric push rod 14, the connecting block 15, the rotating disk 17, the cutting blade 18, the grinder 19, the fixed rod 29, the movable rod 31, the movable block 32, the heating block 33 and the cooling pipe 26 to move horizontally. When the inclined surface of the movable block 32 fits the shaft hole of the housing 9, the annular spring 30 will be compressed, which can move the movable block 32 and the movable rod 31 so that the heating block 33 fits the inner wall of the shaft hole of the housing 9, thereby moving the cutting blade 18. 8. The grinder 19, the movable block 32, and the heated block 33 move into the shaft hole of the housing 9. When the movable block 32 moves, the receiver 41 is also driven to move. When the shaft hole of the housing 9 is switched or polished, the elastic force of the annular spring 30 allows the movable block 32 to always fit the inner wall of the shaft hole of the housing 9. The distance between the receiver 41 and the distance sensor 40 can be adjusted to determine how far the shaft hole of the housing 9 is from the qualified size, thereby controlling the speed of the servo motor 4 and the switching between the cutting blade 18 and the grinder 19. (3) The electric push rod 14 can sequentially drive the connecting block 15, the rotating disk 17, the cutting knife 18 and the grinder 19 to move upward, so that the cutting knife 18 can fit the inner wall of the shaft hole of the shell 9. The distance between the receiver 41 and the distance sensor 40 can be used to predict how much the electric push rod 14 drives the cutting knife 18 to move upward to fit the inner wall of the shaft hole of the shell 9. The servo motor 4 can sequentially drive the transmission gear 5, the movable gear 6, the intelligent push rod 10, the movable clamping block 11, the fixed clamping block 7 and the shell 9 to rotate. The electric push rod 14 drives the cutting knife 18 to move up and down, so that the shaft hole of the shell 9 can be cut. The distance between the receiver 41 and the distance sensor 40 can be used to know how much the cutting knife 18 has cut on the shell 9, and whether the shaft hole of the shell 9 meets the cutting standard. When the shaft hole of the shell 9 is about to be cut, the servo motor 4 can be controlled to appropriately reduce the speed of the shell 9 to avoid the phenomenon of over-cutting due to the inability to stop in time when the shaft hole of the shell 9 is cut, thereby achieving the purpose of cutting the shaft hole of the shell 9. (4) After the shaft hole of the shell 9 is cut, the motor 16 can drive the rotating disk 17 to rotate ninety degrees, and the positions of the cutting blade 18 and the grinder 19 can be switched and adjusted, so that the grinder 19 can fit the inner wall of the shaft hole of the shell 9. Then, the servo motor 4 drives the shell 9 to rotate and cooperates with the electric push rod 14 to drive the grinder 19 to move up and down, so that the shaft hole of the shell 9 can be polished. The distance between the receiver 41 and the distance sensor 40 can be used to know how much the grinder 19 has polished the shell 9, and whether the size of the shaft hole of the shell 9 meets the qualified standard. When the shaft hole of the shell 9 is about to be polished, the servo motor 4 can be controlled to appropriately reduce the speed of the shell 9 to avoid the phenomenon of over-grinding due to the inability to stop in time when the shaft hole of the shell 9 is polished, thereby achieving the purpose of polishing the shaft hole of the shell 9. (5) When one of the shaft holes on the shell 9 is polished, the cutting blade 18, the grinder 19 and the movable block 32 are first returned to their positions, and then the driving motor 2 can sequentially drive the support plate 3, the servo motor 4, the movable gear 6, the intelligent push rod 10, the movable clamp 11, the fixed clamp 7 and the shell 9 to rotate 90 degrees, so that the shell 9 can be turned over. Then, according to the above principle, the cutting blade 18, the grinder 19 and the movable block 32 are adjusted and moved to the unprocessed shaft hole of the shell 9 for cutting, grinding and testing. Therefore, after the cutting and grinding of one shaft hole of the shell 9 are completed, the shell 9 can be automatically turned over to complete the cutting and grinding of the other shaft hole of the shell 9. The grinding operation further improves the working efficiency of the cutting and grinding of the shaft hole of the housing 9, and can realize double-sided turning and double-sided grinding of the shaft hole of the housing 9. Through the above principle, the purpose of the shaft hole cutting and grinding of the housing 9 can be realized as one and the double-sided cutting and double-sided grinding of the shaft hole of the housing 9 can be realized. After the shaft hole of the housing 9 is cut, it can be polished immediately. At the same time, after one shaft hole of the housing 9 is processed, the other shaft hole on the housing 9 can be processed immediately. There is no need to disassemble, clamp, transport and re-position the shaft hole of the housing 9, which can reduce the steps of the housing 9 processing, improve the efficiency of the housing 9 processing, ensure the accuracy of the shaft hole processing of the housing 9, and reduce the scrap rate of the reducer housing 9; (6) The first valve 27 and the second valve 28 are in an open-closed state. When the axial hole of the shell 9 is cut, the first hose 24 is in an open state and the second hose 25 is in a closed state. Therefore, when the axial hole of the shell 9 is cut, the emulsion in the emulsification chamber 21 can be sprayed on the axial hole of the shell 9 and the cutting blade 18 through the first hose 24 and the cooling pipe 26 in sequence by the liquid pump 23. The axial hole of the shell 9 and the cutting blade 18 being cut can be cooled, thereby preventing the axial hole of the shell 9 from being deformed and damaged due to excessive temperature during cutting, and at the same time reducing the probability of damage to the cutting blade 18; (7) When the motor 16 drives the rotating disk 17 to rotate 90 degrees and completes the switching of the cutting blade 18 and the grinder 19, the rotating disk 17 will also drive the arc rack 44 to rotate 90 degrees. When the arc rack 44 rotates, it will mesh with the first gear 46 and the second gear 47 in turn, and then drive the first gear 46 and the second gear 47 to rotate, so that the first valve 27 can be closed and the second valve 28 can be opened, so that the first hose 24 is closed and the second hose 25 is opened. Therefore, when the shaft hole of the shell 9 is ground, the oil-based liquid in the oil-based chamber 22 can be sprayed on the shaft hole of the shell 9 and the cutting blade 18 in turn through the second hose 25, the first hose 24 and the cooling pipe 26 through the liquid pump 23, so that the shaft hole of the shell 9 and the grinder 19 being ground can be cooled, so as to prevent the shaft hole of the shell 9 from being deformed and damaged due to excessive temperature during grinding, and at the same time, the probability of damage to the grinder 19 can be reduced; (8) When one shaft hole on the housing 9 is polished and another shaft hole needs to be cut, the motor 16 drives the rotating disk 17 to rotate 90 degrees in the opposite direction according to the above principle. When the cutting blade 18 and the grinder 19 are switched again, the rotating disk 17 also drives the arc rack 44 to rotate 90 degrees in the opposite direction. The arc rack 44 drives the second gear 47 and the first gear 46 to rotate again, which can open the first valve 27 and close the second valve 28, so that the first hose 24 is opened and the second hose 25 is closed. Then, according to the above principle, When the cutting blade 18 and the grinder 19 are switched, the opening and closing of the first hose 24 and the second hose 25 are automatically switched. When the shaft hole of the housing 9 is cut, the first hose 24 is in the open state and the second hose 25 is in the closed state. When the shaft hole of the housing 9 is grinded, the first hose 24 is in the closed state and the second hose 25 is in the open state. This can save the cost of coolant when cutting the shaft hole of the housing 9 and ensure the smoothness of the shaft hole of the housing 9 when grinding. The switching of the two coolants can be automatically completed when the cutting blade 18 and the grinder 19 are switched. (9) The inner wall of the shell 9 shaft hole will be heated during cutting and grinding, and the heat will be transferred to the heat block 33 and then to the adjustment block 34. The adjustment block 34 can detect the temperature of the shell 9 shaft hole during cutting and grinding. When the temperature of the shell 9 shaft hole is high during processing, the adjustment block 34 will expand due to the high temperature. The size of the expansion of the adjustment block 34 can be controlled by the temperature. Therefore, the expansion and contraction of the adjustment block 34 will change with the temperature of the shell 9 shaft hole during processing. The expansion and contraction of the adjustment block 34 will drive the moving rod 35 to move. When the moving rod 35 moves, it will drive the wedge block 36, the connecting rod 38 and the water baffle 39 to move downward in turn, and the size of the fluid gap between the top of the water baffle 39 and the inner side of the cooling pipe 26 can be adjusted. When the wedge block 36 moves, the telescopic spring 37 will be pulled, and the temperature of the adjustment block 34 will be heated. The higher the temperature, the greater the expansion, the greater the range of the water baffle 39 moving downward, the larger the fluid gap, and the amount of coolant passing through the fluid gap will also increase. The lower the temperature at which the regulating block 34 is heated, the smaller the expansion, the smaller the range of the water baffle 39 moving downward, the smaller the fluid gap, and the smaller the amount of coolant passing through the fluid gap. The flow rate of the coolant can be controlled according to the temperature at which the shaft hole of the shell 9 is heated when the cutting knife 18 and the grinder 19 process the shaft hole of the shell 9. On the one hand, when the processing temperature of the shaft hole of the shell 9 is too high, the shaft hole overheating and deformation caused by insufficient coolant flow can be avoided, thereby ensuring the accuracy of the shaft hole processing. On the other hand, when the processing temperature of the shaft hole of the shell 9 is too low, vibration and chattering caused by excessive coolant flow can be avoided, thereby preventing waste caused by excessive coolant spraying.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
