[0011] Preferably, the storage assembly comprises a placement box and a connection box, wherein the inner wall of the placement box is rotatably connected to a second shaft running through one side of the connection box via a bearing, and a cover plate located on the top side of the placement box is fixedly sleeved on the outer side of the second shaft.

[0012] Preferably, a slide groove is provided on one side of the top of the connection box, a pull rod is slidably connected to the inner side of the slide groove, and a ratchet hinged to the inner wall of the connection box is fixed to the bottom of the pull rod.

[0014] Preferably, one side of the placement box is fixed to one side of the lathe body, and one side of the connection box is fixed to one side of the placement box.

[0015] To achieve the above object, the present invention also provides the following technical solution: a processing method for producing a non-circular cross-section hydraulic tensioner cylinder, according to the processing system, the steps are: (1) When it is necessary to process the non-circular cross-section of the tensioner cylinder part, first clamp the part on one side of the three-jaw chuck, then install the tool of the lathe body on one side of the tool holder, and enter the non-circular cross-section processing program on the operation screen. At this time, the tool contacts the part and processes the non-circular cross-section of the tensioner cylinder; (2) After a certain period of processing, in order to ensure that the cutting accuracy of the tool for processing the parts is consistent, the tool head stops running, the control system on the lathe records the cutting point at that location, and then the worn tool is removed and placed on the top side of the cover plate. The cover plate rotates around the second rotating shaft. Since the second rotating shaft is eccentrically set, a gap is generated between the cover plate and the placement box during the rotation process, so that the cover plate drives the second rotating shaft to rotate, and at the same time, the second rotating shaft drives the ratchet wheel to rotate, so that the pawl slides on the inside of the ratchet teeth of the ratchet wheel, and at the same time, a gap is generated between the cover plate and the placement box. Then the worn tool can be placed inside the placement box; (3) Then pull the pull rod upward so that it slides inside the slide slot. At the same time, the pull rod drives the pawl to leave the inside of the ratchet teeth of the ratchet wheel. Press one side of the cover plate to rotate it so that the cover plate is horizontal on the inside of the placement box. Then release the pulling force of the pull rod so that the pawl is inserted into the inside of the ratchet teeth of the ratchet wheel. (4) Store worn tools in a centralized storage box to facilitate staff to track tool usage and wear, and thus formulate a reasonable tool replacement plan; (5) Install the new tool on the lathe body, and then the control system of the lathe calculates the arc tangent of the cutting point based on the recorded chip point according to the processing drawing parameters of the non-circular section processing program of the machined part, and then moves the tool to the tangent through the tool head, and starts the tool to approach the recorded cutting point in the tangent direction; (6) When the tool moves to coincide with the cutting point, the lathe control system restores the tool to the original input non-circular section machining program to continue cutting; (7) When the tool on one side of the tool holder processes the part, the coolant pump starts to work and sprays the coolant inside the liquid storage tank to the tool through the spray pipe to reduce the temperature of the tool. At this time, the coolant after cooling the tool flows into the inside of the liquid storage tank on the inside of the base under the action of gravity; (8) Then press the switch to control the motor to rotate. When the motor and the fan blade rotate, the air is blown to the inside of the fin, which will cause heat exchange between the air and the fin. Since one end of the fin is inserted into the inside of the liquid storage tank, when the air blows through the fin, the fin can cool the coolant inside the liquid storage tank; (9) When the coolant passes through the filter screen, the filter screen blocks the metal debris in the coolant at its top. At this time, the second bevel gear is meshed with the first bevel gear, so that the first bevel gear drives the reciprocating screw to rotate. When the reciprocating screw rotates, the connecting frame threadedly connected to it slides along the slide column. When the connecting frame moves along the slide column to one side of the box body, the top of the scraper hinged at the bottom of the connecting frame hits the bottom of the limit block. (10) The scraper slides on the top of the filter, pushing the metal debris remaining on the top of the filter to the inside of the box. When the connecting frame moves along the slide column toward the motor side, the top of the scraper leaves the bottom of the limit block, so that when the scraper moves, the support force of the limit block is lacking and the top of the filter does not effectively scrape, thereby preventing the metal debris from moving to the left side of the top of the filter under the action of the scraper, and collecting the metal debris uniformly inside the box; (11) When a certain amount of metal debris is collected inside the box, you only need to pull the box to one side to clean the metal debris inside the box.

[0016] Compared with the prior art, the present invention adopts the above technical solution and has the following technical effects: 1. Place the tool on the top side of the cover plate. At this time, the cover plate rotates with the second shaft, so that the second shaft drives the ratchet to rotate, and the pawl slides on the inside of the ratchet teeth of the ratchet. At the same time, a gap is generated between the cover plate and the storage box. The worn tool is placed on the inside of the storage box, and one side of the cover plate is pressed to rotate it, so that the cover plate is horizontal on the inside of the storage box. The ratchet and the pawl are used together, and the storage box is used to store the tool, which reduces the chance of workers directly contacting the tool, especially when the tool is worn and may become sharp or unstable, which greatly reduces the safety risk of the operator. Storing the worn tools in the storage box is conducive to subsequent maintenance and management, and it is easier to track the usage and wear of the tools, so as to formulate a reasonable tool replacement plan and reduce maintenance costs.

[0017] 2. The coolant inside the liquid storage tank is sprayed to the tool through the spray pipe to reduce the temperature of the tool. When the motor output shaft drives the fan blade to rotate, air is blown to the inside of the fin to cool the coolant inside the liquid storage tank. Spraying coolant to the tool in time can quickly reduce the high temperature generated by friction during the processing of the tool, thereby slowing down the wear rate of the tool and extending the service life of the tool. The coolant is recycled to reduce the waste and discharge of coolant. The air is used to exchange heat with the fins to cool the coolant in the liquid storage tank, which also reduces the dependence on external cooling equipment and reduces energy consumption.

[0018] 3. The metal debris in the coolant is blocked at the top of the filter screen, and the second bevel gear is meshed and connected with the first bevel gear, so that the first bevel gear drives the reciprocating screw to rotate, and the top of the scraper hinged at the bottom of the connecting frame abuts against the bottom of the limit block, so that the scraper slides on the top of the filter screen, and the metal debris remaining on the top of the filter screen is pushed to the inside of the box. The filter screen effectively blocks and collects the metal debris in the coolant, and the metal debris can be further recycled, thereby improving resource utilization. When a certain amount of metal debris is collected inside the box, it can be easily pulled out for cleaning without stopping the machine or disassembling other components, thereby enhancing the flexibility and ease of use of the equipment.

[0019] 4. One motor drives the circulation, filtration and automatic cleaning of the coolant, which simplifies the operation process, improves production efficiency and the automation level of the equipment, reduces the number of mechanical power source parts, and reduces potential failure points and maintenance requirements.

[0026] In order to facilitate the cleaning of metal debris on the top of the filter screen 29, a cleaning mechanism is provided, which includes a limit plate 214 and a connecting frame 28. A scraper 27 is hinged on one side of the bottom of the connecting frame 28. A reciprocating screw rod 25 is rotatably connected to one side of the limit plate 214 through a bearing. The outer side of the reciprocating screw rod 25 is threadedly connected to one side of the connecting frame 28. A sliding column 26 that movably penetrates one side of the connecting frame 28 is connected between one side of the limit plate 214 and the inner side wall of the base 5. A plurality of sliding columns 26 can be provided according to actual needs, so that a plurality of sliding columns 26 can movably penetrate the connecting frame 28. One side of the connecting frame 28 provides stable sliding of the connecting frame 28, and a limit block 218 is fixed on one side of the motor 22 at the bottom side of the connecting frame 28. When the reciprocating screw rod 25 rotates, the connecting frame 28 threadedly connected thereto slides along the sliding column 26. When the connecting frame 28 moves along the sliding column 26 toward the side of the box 210, the top of the scraper 27 hinged at the bottom of the connecting frame 28 abuts against the bottom of the limit block 218, so that the scraper 27 slides on the top of the filter screen 29, pushing the metal debris remaining on the top of the filter screen 29 to the inside of the box 210.

[0027] A filter screen 29 is installed on the fixed side of the top of the liquid storage tank 215 and is slidably connected to the bottom side of the scraper 27. When the coolant passes through the filter screen 29, the filter screen 29 blocks the metal debris in the coolant at its top. At this time, the second bevel gear 216 is meshed and connected with the first bevel gear 213, so that the first bevel gear 213 drives the reciprocating screw rod 25 to rotate. A coolant pump 211 is installed on the bottom of the inner wall of the liquid storage tank 215. The coolant pump 211 starts to work and the coolant inside the liquid storage tank 215 is sprayed The pipe 21 sprays toward the tool to reduce the temperature of the tool. At this time, the coolant after cooling the tool flows into the inner side of the liquid storage tank 215 on the inner side of the base 5 under the action of gravity. The outlet end of the coolant pump 211 is connected with the spray pipe 21 located on one side of the tool holder 8. A first bevel gear 213 is fixed to one end of the reciprocating screw rod 25. A second bevel gear 216 meshingly connected to the first bevel gear 213 is fixedly sleeved on the outer side of the first rotating shaft 217. The diameter of the second bevel gear 216 is smaller than that of the first bevel gear 213. A box body 210 is inserted into one side of the base 5, and the box body 210 is located on one side of the liquid storage tank 215. One side of the support frame 23 is fixed to the inner wall of the base 5, and the liquid storage tank 215 is installed on the inner side of the base 5. The bottom of the limiting plate 214 is fixed to the top side of the liquid storage tank 215, so that metal debris is uniformly collected on the inner side of the box body 210. When a certain amount of metal debris is collected inside the box body 210, it is only necessary to pull the box body 210 to one side to clean the metal debris inside the box body 210.

[0028] In order to facilitate the storage of worn tools, a storage assembly 3 is provided. The storage assembly 3 includes a placement box 31 and a connection box 37. The inner wall of the placement box 31 is rotatably connected to a second shaft 33 that runs through one side of the connection box 37 through a bearing. The outer side of the second shaft 33 is fixedly sleeved with a cover plate 38 located on one side of the top of the placement box 31. The tool is placed on one side of the top of the cover plate 38. At this time, the cover plate 38 rotates with the second shaft 33. Since the second shaft 33 is eccentrically arranged, the cover plate 38 drives the second shaft 33 to rotate, and the worn tools are stored in the placement box 31 in a centralized manner, which is beneficial to subsequent maintenance and management. It is easier to track the use and wear degree of the tools, thereby formulating a reasonable tool replacement plan and reducing maintenance costs. The cooperation of the pawl 35 and the ratchet 36 prevents the cover plate 38 from being opened at will. A slide groove 39 is provided on one side of the top of the connecting box 37, and a pull rod 32 is slidably connected to the inner side of the slide groove 39. A pawl 35 hinged to the inner wall of the connecting box 37 is fixed at the bottom of the pull rod 32. A ratchet 36 is fixedly sleeved on the outer side of one end of the second rotating shaft 33. The pawl 35 is located on the inner side of the ratchet teeth of the ratchet 36. A spring 34 is sleeved on the outer side of the pull rod 32. The two ends of the spring 34 are respectively connected to the pawl 35 and one side of the connecting box 37. One side of the placement box 31 is fixed to one side of the lathe body 1, and one side of the connecting box 37 is fixed to one side of the placement box 31. The second rotating shaft 33 drives the ratchet 36 to rotate, so that the pawl 35 slides on the inner side of the ratchet teeth of the ratchet 36, and at the same time, a gap is generated between the cover plate 38 and the placement box 31, and then the worn tool can be placed on the inner side of the placement box 31.

[0029] Working principle: When it is necessary to process the non-circular cross section of the tensioner oil cylinder part, first clamp the part on one side of the three-jaw chuck 7, then install the tool of the lathe body 1 on one side of the tool holder 8, and input the non-circular cross section processing program on the operation screen 4. At this time, the tool contacts the part and processes the non-circular cross section of the tensioner oil cylinder; Since the material of the tensioner cylinder is relatively hard, with a hardness of about HRC40, the same tool will accelerate the wear of the harder material. When the worn tool is disassembled, the tool is placed on the top side of the cover 38. At this time, the cover 38 rotates around the second rotating shaft 33. Since the second rotating shaft 33 is eccentrically arranged, a gap is generated between the cover 38 and the placement box 31 during the rotation. At this time, the cover 38 drives the second rotating shaft 33 to rotate, and at the same time, the second rotating shaft 33 drives the ratchet 36 to rotate, so that the pawl 35 slides on the inside of the ratchet teeth of the ratchet 36, and at the same time, a gap is generated between the cover 38 and the placement box 31. Subsequently, the worn tool can be placed on the inside of the placement box 31, and then the pull rod 32 is pulled upward to make the pull rod 32 slide in the slide groove 39 The pull rod 32 is pulled on the side, and at the same time, the pawl 35 is driven by the pull rod 32 to leave the inner side of the ratchet teeth of the ratchet wheel 36, and one side of the cover plate 38 is pressed to rotate it, so that the cover plate 38 is horizontally placed on the inner side of the storage box 31, and then the pulling force of the pull rod 32 is released, so that the pawl 35 is inserted into the inner side of the ratchet teeth of the ratchet wheel 36, so as to prevent the worn tools from being placed randomly and contacting with the workers. Through the cooperation of the ratchet wheel 36 and the pawl 35, the storage box 31 is used to store the tools, which reduces the chances of workers directly contacting the tools, especially when the tools are worn and may become unstable, which greatly reduces the safety risks of the operators. The worn tools are stored in the storage box 31, which is conducive to the subsequent maintenance and management, and it is easier to track the usage and wear of the tools, so as to formulate a reasonable tool replacement plan and reduce maintenance costs.

[0030] When the tool on one side of the tool holder 8 is processing the part, the coolant pump 211 starts to work, and the coolant inside the liquid storage tank 215 is sprayed to the tool through the spray pipe 21 to reduce the temperature of the tool. At this time, the coolant after cooling the tool flows into the inside of the liquid storage tank 215 inside the base 5 under the action of gravity. At this time, the switch is pressed to control the output shaft of the motor 22 to rotate, and the output shaft drives the first rotating shaft 217 to rotate. The first rotating shaft 217 drives the second bevel gear 216 and the fan blade 24 to rotate. When the fan blade 24 rotates, it blows air to the inside of the fin 212, which will make the air and the fin 212 Heat exchange occurs. Since one end of the fin 212 is inserted into the inner side of the liquid storage tank 215, when air blows through the fin 212, the fin 212 can cool the coolant inside the liquid storage tank 215. By timely spraying the coolant to the tool, the high temperature generated by the friction of the tool during the processing can be quickly reduced, thereby slowing down the wear rate of the tool and extending the service life of the tool. The coolant is recycled, reducing the waste and discharge of the coolant. The air is used to perform heat exchange on the fin 212 to cool the coolant in the liquid storage tank 215, which also reduces the dependence on external cooling equipment and reduces energy consumption. When the coolant passes through the filter screen 29, the filter screen 29 blocks the metal debris in the coolant at its top. At this time, the second bevel gear 216 is meshed and connected with the first bevel gear 213, so that the first bevel gear 213 drives the reciprocating screw rod 25 to rotate. When the reciprocating screw rod 25 rotates, the connecting frame 28 threadedly connected thereto slides along the sliding column 26. When the connecting frame 28 moves toward the side of the box body 210 along the sliding column 26, the top of the scraper 27 hinged at the bottom of the connecting frame 28 hits the bottom of the limit block 218, so that the scraper 27 slides on the top of the filter screen 29, and the metal debris remaining on the top of the filter screen 29 is pushed to the inside of the box body 210. When the connecting frame 28 moves toward the side of the motor 22 along the sliding column 26, the top of the scraper 27 leaves the bottom of the limit block 218. At this time, the scraper 27 is When moving, the lack of support force of the limit block 218 prevents effective scraping with the top of the filter screen 29, preventing metal debris from moving to the top left side of the filter screen 29 under the action of the scraper 27, and collecting the metal debris on the inside of the box 210. When a certain amount of metal debris is collected inside the box 210, it is only necessary to pull the box 210 to one side to clean the metal debris inside the box 210. The power of a motor 22 can be used to cool the coolant and clean the metal debris, reducing the number of mechanical power source parts and the failure rate of the device. A motor 22 simultaneously drives the circulation, filtration and automatic cleaning of the coolant, simplifying the operation process, improving production efficiency and the automation level of the equipment, reducing the number of mechanical power source parts, and reducing potential failure points and maintenance requirements.

[0031] The metal debris in the coolant is effectively blocked and collected by the filter 29, and the metal debris can be further recycled, thereby improving resource utilization. When a certain amount of metal debris is collected inside the box 210, it can be easily pulled out for cleaning without stopping the machine or disassembling other components, thereby enhancing the flexibility and ease of use of the equipment.

[0032] The processing method for producing a non-circular cross-section hydraulic tensioner cylinder, according to the processing system, comprises the following steps: (1) When it is necessary to process the non-circular cross-section of the tensioner cylinder part, first clamp the part on one side of the three-jaw chuck, then install the tool of the lathe body on one side of the tool holder, and enter the non-circular cross-section processing program on the operation screen. At this time, the tool contacts the part and processes the non-circular cross-section of the tensioner cylinder; (2) After a certain period of processing, in order to ensure that the cutting accuracy of the tool for processing the parts is consistent, the tool head stops running, the control system on the lathe records the cutting point at that location, and then the worn tool is removed and placed on the top side of the cover plate. The cover plate rotates around the second rotating shaft. Since the second rotating shaft is eccentrically set, a gap is generated between the cover plate and the placement box during the rotation process, so that the cover plate drives the second rotating shaft to rotate, and at the same time, the second rotating shaft drives the ratchet wheel to rotate, so that the pawl slides on the inside of the ratchet teeth of the ratchet wheel, and at the same time, a gap is generated between the cover plate and the placement box. Then the worn tool can be placed inside the placement box; (3) Then pull the pull rod upward so that it slides inside the slide slot. At the same time, the pull rod drives the pawl to leave the inside of the ratchet teeth of the ratchet wheel. Press one side of the cover plate to rotate it so that the cover plate is horizontal on the inside of the placement box. Then release the pulling force of the pull rod so that the pawl is inserted into the inside of the ratchet teeth of the ratchet wheel. (4) Store worn tools in a centralized storage box to facilitate staff to track tool usage and wear, and thus formulate a reasonable tool replacement plan; (5) Install the new tool on the lathe body, and then the control system of the lathe calculates the arc tangent of the cutting point based on the recorded chip point according to the processing drawing parameters of the non-circular section processing program of the machined part, and then moves the tool to the tangent through the tool head, and starts the tool to approach the recorded cutting point in the tangent direction; (6) When the tool moves to coincide with the cutting point, the lathe control system restores the tool to the original input non-circular section machining program to continue cutting; (7) When the tool on one side of the tool holder processes the part, the coolant pump starts to work and sprays the coolant inside the liquid storage tank to the tool through the spray pipe to reduce the temperature of the tool. At this time, the coolant after cooling the tool flows into the inside of the liquid storage tank on the inside of the base under the action of gravity; (8) Then press the switch to control the motor to rotate. When the motor and the fan blade rotate, the air is blown to the inside of the fin, which will cause heat exchange between the air and the fin. Since one end of the fin is inserted into the inside of the liquid storage tank, when the air blows through the fin, the fin can cool the coolant inside the liquid storage tank; (9) When the coolant passes through the filter screen, the filter screen blocks the metal debris in the coolant at its top. At this time, the second bevel gear is meshed with the first bevel gear, so that the first bevel gear drives the reciprocating screw to rotate. When the reciprocating screw rotates, the connecting frame threadedly connected to it slides along the slide column. When the connecting frame moves along the slide column to one side of the box body, the top of the scraper hinged at the bottom of the connecting frame hits the bottom of the limit block. (10) The scraper slides on the top of the filter, pushing the metal debris remaining on the top of the filter to the inside of the box. When the connecting frame moves along the slide column toward the motor side, the top of the scraper leaves the bottom of the limit block, so that when the scraper moves, the support force of the limit block is lacking and the top of the filter does not effectively scrape, thereby preventing the metal debris from moving to the left side of the top of the filter under the action of the scraper, and collecting the metal debris uniformly inside the box; (11) When a certain amount of metal debris is collected inside the box, you only need to pull the box to one side to clean the metal debris inside the box.

[0033] The tangents in step (5) include straight line tangents and elliptical tangents. When machining the outer arc surface of the hydraulic tensioner cylinder with a non-circular cross-section, the straight line tangent method is used for machining, such as Fig.11 As shown in the figure, the tool approaches the tangent point in the straight tangent direction, and after the overlap, the part is cut along the original cutting trajectory; when machining the inner cylinder arc surface of the hydraulic tensioner cylinder with a non-circular cross-section, the elliptical tangent method is used for machining, such as Fig.12 As shown, the tool uses the midpoint of the smooth surface of the elliptical tangent and the cutting point as tangent points. The tool moves along an elliptical trajectory and approaches the tangent point. After overlapping, the part is cut along the original cutting trajectory.

[0034] By approaching the cutting point in a tangential manner, it is avoided that the tool directly approaches the cutting position or starts after being at the cutting position, which may cause damage to the part or deteriorate the machining accuracy.
