Description

Technical Field

[0001] A cylinder block production line, belonging to the technical field of cylinder block production equipment. Background Technology

[0002] A single retractable hydraulic prop refers to a prop that uses fluid pressure to generate working resistance and achieves lifting and unloading. A single hydraulic prop consists of a cylinder, piston, valves, and other parts. The three-way valve is the heart of the external injection type single hydraulic prop; it comprises a check valve, an unloading valve, and a safety valve. The check valve supplies fluid to the prop, the unloading valve unloads fluid and allows the prop to return to its original position, and the safety valve ensures the prop maintains constant resistance.

[0003] During the production of a single hydraulic prop cylinder, the cylinder body needs to be machined in sequence: turning the outer diameter, boring the inner hole, and milling the groove. Turning the outer diameter means turning the outer diameter of the cylinder body to ensure the accuracy of the outer diameter. Boring the inner hole means machining the inner wall of the cylinder body to ensure the accuracy of the inner diameter. Milling the groove refers to milling a groove on one side of the outer wall at the end of the cylinder body to axially lock the cylinder body and the base through a steel wire.

[0004] Currently, the cylinder body of a single hydraulic prop needs to be machined sequentially on a lathe and a boring machine during the production process. After machining, grooves are milled on the outer walls of both ends of the cylinder body. The cylinder body is first transported to one side of the lathe for external turning. After external turning, the cylinder body is then transported to the boring machine for internal boring. After internal boring, the cylinder body is transferred to the groove milling area for groove milling. Throughout the entire process, the cylinder body needs to be manually transferred, which makes it impossible to achieve assembly line production. This results in slow cylinder body production speed and requires a lot of manual labor for cylinder body transfer, leading to high labor costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a cylinder production line that can automatically complete the outer turning, boring and milling of cylinder blocks, so as to realize the assembly line production of cylinder blocks.

[0006] The technical solution adopted by the present invention to solve its technical problem is: the cylinder production line is characterized by: including a feeding device, a lathe, a boring machine, a milling device, and a storage device arranged in sequence, a robot arm arranged between the feeding device and the milling device, and an unloading device arranged between the milling device and the storage device, wherein the robot arm transports the cylinders on the feeding device to the lathe, the milling machine and the milling device in sequence.

[0007] Preferably, two robotic arms are provided, one positioned between the loading device and the lathe, and the other positioned between the lathe and the milling device. One robotic arm transports the cylinder block from the loading device to the lathe, while the other robotic arm can transfer the machined cylinder block from the lathe to the boring machine and the milling device, ensuring the cylinder block loading speed and preventing the lathe or boring machine from being idle.

[0008] Preferably, two boring machines are arranged side by side. This arrangement ensures that the boring speed of the cylinder block's inner bore matches the turning speed of the lathe's outer diameter, preventing idle time on the lathe.

[0009] Preferably, a transfer device is provided between the lathe and the boring machine. The transfer device can temporarily store the cylinder block after it has been turned by the lathe, so that both the lathe and the boring machine can work at full capacity.

[0010] Preferably, the unloading device includes an unloading cylinder and a cylinder pusher plate. One end of the cylinder pusher plate is rotatably connected to the storage device, and the other end extends to the lower part of the milling device. The piston rod of the unloading cylinder is connected to the cylinder pusher plate. The unloading cylinder pushes the cylinder pusher plate to move, causing the cylinder pusher plate to push the milled cylinder on the milling device onto the storage device, thereby realizing the automatic unloading of the cylinder after milling.

[0011] Preferably, the cylinder push plate has a baffle at the end away from the storage device, and the baffle is inclined upwards gradually in the direction away from the storage device. The baffle on the cylinder push plate can block the cylinder to prevent it from falling off the cylinder push plate.

[0012] Preferably, the storage device includes a storage platform that is gradually inclined downwards away from the milling device, and a storage baffle is provided at the end of the storage platform away from the milling device. The unloading device pushes the cylinder onto the storage platform, which is inclined, allowing the cylinders to be closely arranged on the platform, facilitating subsequent transfer of the cylinders.

[0013] Preferably, the feeding device includes a feeding platform, a lifting device, and an axial positioning device. The feeding platform is inclined and gradually decreases in the direction of approaching the lathe. A feeding baffle is provided at the end of the feeding platform near the lathe. The lifting device and the axial positioning device are both located at the end of the feeding platform near the lathe. The lifting device is set below the feeding platform, and the axial positioning device is set above the feeding platform. The axial positioning device and the lifting device are positioned opposite each other.

[0014] Compared with the prior art, the beneficial effects of this invention are: The robotic arm on this cylinder block production line can sequentially transport cylinder blocks from the loading device to a lathe, boring machine, and milling device. The lathe can perform external turning on the cylinder block, the boring machine can bore the internal hole of the cylinder block, and the milling device can mill grooves on the outer walls at both ends of the cylinder block. The unloading device can transport the milled cylinder block to the storage device, thus realizing a streamlined production line for cylinder blocks. The cylinder block processing has a high degree of automation. During the processing, the cylinder block does not need to be transported, which makes the cylinder block processing speed fast, saves a lot of manpower, and reduces labor costs.

Detailed Implementation

[0037] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention necessarily exceeds the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but still fall within the protection scope of this application.

[0038] Figures 1-21 This is the preferred embodiment of the present invention, which is described below in conjunction with the accompanying drawings. Figures 1-21 The present invention will be further described below.

[0039] A cylinder production line includes a feeding device 2, a lathe 3, a boring machine 5, a milling device 6, and a storage device 8 arranged in sequence, a robot 1 arranged between the feeding device 2 and the milling device 6, and an unloading device 7 arranged between the milling device 6 and the storage device 8. The robot 1 transports the cylinder 40 on the feeding device 2 to the lathe 3, the milling machine 5 and the milling device 6 in sequence. The robotic arm 1 of this cylinder block production line can sequentially transport the cylinder block 40 from the feeding device 2 to the lathe 3, boring machine 4, and milling device 6. The lathe 3 can perform external turning on the cylinder block 40, the boring machine 5 can bore the internal hole of the cylinder block 40, the milling device 6 can mill grooves on the outer walls at both ends of the cylinder block 40, and the unloading device 7 can transport the milled cylinder block 40 to the storage device 8, thus realizing the assembly line production of the cylinder block 40. The cylinder block 8 has a high degree of automation in processing. During the processing, the cylinder block 8 does not need to be transported, which makes the processing speed of the cylinder block 8 fast, saves a lot of manpower, and reduces labor costs.

[0040] Specifically: such as Figure 1 As shown: This cylinder block production line also includes a transfer device 4, which is located between the lathe 3 and the boring machine 5. The transfer device 4 can temporarily store the cylinder block 40 processed by the lathe 3. There are two boring machines 5 arranged side by side, and both boring machines 5 are located between the transfer device 4 and the milling device 6.

[0041] Two robotic arms 1 are provided. One robotic arm 1 is located between the loading device 2 and the transfer device 4, and transports the cylinder block 40 on the loading device 2 to the lathe 3, and then transfers the cylinder block 40 after turning to the transfer device 4. The other robotic arm 1 is located between the transfer device 4 and the milling device 6, and transports the cylinder block 40 on the transfer device 4 to the idle boring machine 5, and then transfers the bored cylinder block 40 to the milling device 6 for milling.

[0042] like Figures 2-3 As shown: The loading device 2 includes a loading platform 9, a loading baffle 10, a lifting device, and an axial positioning device. The loading platform 9 is inclined downwards towards the lathe 3. A convex loading baffle 10 is provided on the side of the loading platform 9 closest to the lathe 3, with two baffles 10 arranged side-by-side and spaced apart. Two lifting devices are located on the lower side of the end of the loading platform 9 closest to the lathe 3, each with an upward-facing V-shaped lifting section at its top, capable of radially positioning the cylinder 40. An axial positioning device is also provided at the end of the loading platform 9 closest to the lathe 3, positioned higher than the loading platform 9, and directly opposite the lifting device.

[0043] The loading device 2 also includes a loading frame 17 and a loading platform pushing device. The loading platform 9 is located on the upper side of the loading frame 17. One end of the loading platform 9 near the lathe 3 is rotatably connected to the loading frame 17, and the other end is connected to the loading platform 9 by the loading platform pushing device. The loading platform pushing device can push the loading platform 9 to rotate, thereby adjusting the tilt angle of the loading platform 9. The lifting device and the axial positioning device are both mounted on the loading frame 17.

[0044] The lifting device includes a lifting frame 14 and a lifting cylinder 15. The lifting cylinder 15 is vertically mounted on the loading frame 17. The lifting frame 14 is mounted on the output shaft of the lifting cylinder 15 and rises and falls synchronously with the output shaft of the lifting cylinder 15. The lifting part is located on the top of the lifting frame 14 and can position the lifted cylinder 40.

[0045] When the cylinders are placed on the loading platform 9, the close arrangement of adjacent cylinders 40 makes it difficult for the robot arm 1 to individually grasp one cylinder 40 from both sides. The lifting device can lift one cylinder 40 near the lathe 3 end, making it higher than the other cylinders 40. At this time, the robot arm 1 can clamp the cylinder 40 from both sides, avoiding obstruction from adjacent cylinders 40. After lifting the cylinder 40, the side of the lifting frame 14 blocks adjacent cylinders 40 to prevent the cylinder 40 from rolling to the bottom of the lifting frame 14 and obstructing its reset.

[0046] The axial positioning device includes an axial positioning cylinder 13 and an axial positioning plate 11. The axial positioning plate 11 and the axial positioning cylinder 13 are respectively arranged on opposite sides of the loading platform 9. An axial push plate is installed on the piston rod of the axial positioning cylinder 13. The axial push plate is arranged opposite to the axial positioning plate 11. The axial positioning cylinder 13 is installed on the loading rack 17 through an axial support plate 12.

[0047] When the lifting device lifts the cylinder 40 near the lathe 3, the axial positioning cylinder 13 extends and pushes the cylinder 40 to move through the axial push plate, so that the end of the cylinder 40 is positioned on the axial positioning plate 11, thereby realizing the axial positioning of the cylinder 40.

[0048] The loading platform pushing device is a loading frame pushing cylinder 16, which is rotatably mounted on the loading frame 17. The piston rod of the loading frame pushing cylinder 16 is rotatably connected to the loading platform 9, thereby pushing the loading platform 9 to move and adjust the angle of the loading platform 9.

[0049] The structure of the transfer device 4 is the same as that of the loading device 2. The only difference is that a lifting device is also provided at the end of the transfer device 4 that is close to the lathe 4 to receive the cylinder 40 gripped by the robot and lower it onto the loading platform 9 of the transfer device 4. The specific structure of the transfer device 4 will not be described here.

[0050] like Figures 4-6 As shown: The robotic arm 1 includes a horizontal moving device, a vertical moving device, a lifting device, and a clamping device. Both the horizontal and vertical moving devices are connected to the lifting devices. Two lifting devices are arranged side-by-side, and each lifting device is equipped with a clamping device. Each lifting device and each clamping device operates independently. The horizontal and vertical moving devices can simultaneously drive the two lifting devices to move horizontally, adjusting their positions to facilitate the clamping devices gripping the cylinder 40 and transferring the clamped cylinder 40 to a designated position. The two lifting devices operate independently, each driving the corresponding clamping device to rise and fall. The two clamping devices operate independently, capable of clamping and releasing the cylinder 40 separately. When loading the cylinder 40, one clamping device clamps the cylinder 40 to be processed and moves it to the upper side of the machine tool. After the idle clamping device removes the processed cylinder 40, the other clamping device directly places the cylinder 40 to be processed onto the machine tool. The distance the clamping devices move during the entire loading process is greatly reduced, increasing the loading speed of the cylinder 40.

[0051] In this embodiment, the longitudinal moving device is installed on the transverse moving device and moves synchronously with the transverse moving device. The longitudinal moving device is also connected to two lifting devices and drives the two lifting devices to move synchronously. The two lifting devices are respectively set on both sides of the longitudinal moving device. Each lifting device is equipped with a clamping device. Each lifting device works independently and can drive the clamping device connected to it to move up and down. Each clamping device works independently and can clamp or release the cylinder 40 respectively.

[0052] The lateral movement device includes a lateral drive unit, a lateral movement frame 21, and a robotic arm body. The robotic arm body includes columns 18 and a lateral beam 19. The lateral beam 19 is horizontally positioned, and the columns 18 are vertically positioned below the lateral beam 19. Several columns 18 are arranged side-by-side and spaced apart. The top of each column 18 is fixedly connected to the lateral beam 19, and the bottom is mounted on a precast concrete foundation. The lateral movement frame 21 is slidably mounted on the lateral beam 19. The lateral drive unit is connected to the lateral movement frame 21 and drives the lateral movement frame 21 to move along the lateral beam 19. The longitudinal movement device is mounted on the lateral movement frame 21.

[0053] A transverse guide rail 20 is installed on the transverse beam 19. The transverse guide rail 20 is set horizontally. The transverse moving frame 21 is slidably installed on the transverse guide rail 20. The transverse guide rail 20 can guide the transverse moving frame 21 to ensure that the transverse moving frame 21 moves linearly.

[0054] Transverse guide rails 20 are installed on both sides of the transverse beam 19. The transverse moving frame 21 is a slot-shaped structure with the opening facing downwards. The transverse moving frame 21 covers the outside of the transverse beam 19. The transverse moving frame 21 is slidably connected to the transverse guide rails 20 on both sides of the transverse beam 19, which can ensure high connection strength between the transverse moving frame 21 and the transverse beam 19 and avoid the problem of deformation of the transverse moving frame 21 due to uneven force.

[0055] The lateral drive device can be either a lateral cylinder, with its piston rod connected to the lateral moving frame 21 and pushing it to move horizontally, or a motor driving the lateral moving frame 21 to move via a synchronous belt. Existing technical solutions can be directly adopted for the lateral drive device, and the specific structure of the lateral moving device will not be described here.

[0056] The longitudinal moving device includes a longitudinal drive unit, a longitudinal moving frame 26, and a longitudinal crossbeam 25. The longitudinal crossbeam 25 is disposed above the transverse moving frame 21, with one end fixedly connected to the transverse moving frame 21 and the other end suspended in the air. The longitudinal moving frame 26 is slidably mounted on the longitudinal crossbeam 25. The longitudinal drive unit is connected to the longitudinal moving frame 26 and drives the longitudinal moving frame 26 to move along the longitudinal crossbeam 25. All lifting devices are mounted on the longitudinal moving frame 26.

[0057] There are two longitudinal moving frames 26 located on both sides of the longitudinal beam 25, and each lifting device is installed on the corresponding longitudinal moving frame 26. Both sides of the longitudinal beam 25 are equipped with longitudinal guide rails 27, and each longitudinal moving frame 26 is slidably mounted on the corresponding longitudinal guide rail 27 via a longitudinal slide block 28. The longitudinal drive device is connected to both longitudinal moving frames 26 and drives both longitudinal moving frames 26 to move synchronously.

[0058] The longitudinal drive device can be a longitudinal cylinder, with the piston rod of the cylinder connected to both longitudinal moving frames 26 on both sides, driving the two longitudinal moving frames 26 to move synchronously. Alternatively, the longitudinal drive device can be a motor connected to the longitudinal moving frames 26 via a synchronous belt, with both longitudinal moving frames 26 fixedly connected to the same side of the synchronous belt, thus causing the two longitudinal moving frames 26 to move synchronously. Existing technical solutions can be used for the longitudinal drive device, and its structure will not be described in detail here.

[0059] The lifting device includes a lifting drive device and a lifting frame 30. In this embodiment, the lifting drive device is a vertically arranged lifting cylinder 22. The lifting cylinder 22 is installed on the longitudinal moving frame 26 on the corresponding side. The lifting frame 30 is connected to the piston rod of the lifting cylinder 22 and rises and falls synchronously with it. The clamping device is installed on the lifting frame 30 on the corresponding side.

[0060] The lifting frame 30 is equipped with vertical lifting guide rails 23, and each longitudinal moving frame 26 is equipped with a lifting slide. The lifting slide is slidably connected to the lifting guide rail 23, thereby guiding the lifting of the lifting frame 30 and making its lifting more stable. There are two lifting guide rails 23 on each side of the lifting cylinder 22, and each longitudinal lifting frame 26 has a lifting slide on each side that is slidably connected to the corresponding lifting guide rail 23. The lifting cylinder 22 can also be replaced with a lifting hydraulic cylinder or a lifting electric cylinder.

[0061] Each clamping device includes a clamping frame 31, a clamping plate 24, and a clamping cylinder 29. The clamping frame 31 is installed on the lower side of the lifting frame 30, and the clamping plate 24 is located on the lower side of the clamping frame 30. The clamping plate 24 has two pieces symmetrically arranged on both sides of the clamping frame 31. The clamping cylinder 29 is installed on the clamping frame 31. Both sides of the clamping cylinder 29 are connected to the two clamping plates 24 at the same time, and drive the two clamping plates 24 to move closer or further away at the same time to clamp the cylinder body.

[0062] Each clamping plate 24 is provided with a clamping part 2401 at the bottom. The clamping part 2401 is located on the inner side of the clamping plate 24 and is V-shaped with the opening facing inward. The clamping parts 2401 of the two clamping plates 24 are arranged opposite each other to ensure that the two clamping plates 24 can clamp the cylinder body 40 and prevent slippage between the cylinder body 40 and the clamping plate 24.

[0063] In this embodiment, each clamping frame 31 is equipped with two pairs of clamping plates 24. The two pairs of clamping plates 24 are spaced apart along the moving direction of the longitudinal moving device. Each pair of clamping plates 24 is connected to an independent clamping cylinder 29. The two clamping cylinders 29 operate synchronously to ensure that the two pairs of clamping plates 24 on each clamping frame 31 clamp the cylinder body 40 synchronously, making the clamping of the cylinder body 40 more reliable and stable.

[0064] The lateral movement device of the robot arm 1 drives the longitudinal movement device to move to one side of the cylinder body 40 to be processed. The longitudinal movement device drives the longitudinal movement frame 26 to move and aligns the clamping device with the middle of the cylinder body 40 to be processed. Any one of the lifting cylinders 22 extends, causing the lifting frame 30 to descend until the cylinder body 40 enters between the two clamping plates 24 corresponding to the lifting cylinder 22. Then the clamping cylinder 29 is activated, causing the two clamping plates 24 to move inward synchronously. When the two clamping plates 24 clamp the cylinder body, the lifting cylinder 22 is reset.

[0065] The transverse moving device drives the longitudinal moving device to move above the machine tool and aligns the empty clamping device with the machine tool. At the same time, the longitudinal moving device drives the clamping device to align with the middle of the machined cylinder. The lifting cylinder 22 corresponding to the empty clamping device extends, allowing the machined cylinder 40 to enter between the two clamping plates 24 of the empty clamping device. The clamping cylinder 29 corresponding to the two clamping plates 24 actuates and clamps the machined cylinder 40. Then, the lifting cylinder 22 resets.

[0066] The lateral movement device is activated, and the clamping device that clamps the cylinder body 40 to be processed is aligned with the machine tool. The lifting cylinder 22 on the clamping device extends, and the cylinder body 40 to be processed enters the machine tool to complete the loading of the machine tool. After the loading is completed, the clamping cylinder 29 connected to the lifting cylinder 225 is activated, causing the two clamping plates 24 to release the cylinder body to be processed, and at the same time the lifting cylinder 22 is reset.

[0067] The lateral moving device is activated, causing the longitudinal moving device to move to the upper side of the processed cylinder 40. The longitudinal moving device drives the lifting device to move until the clamping device is aligned with the processed cylinder 40. Then the lifting device drives the processed cylinder 40 to descend and stacks the processed cylinders 40 neatly. The clamping cylinder 29 is activated and releases the processed cylinder 40 with the clamping plate 24. Then the lifting cylinder 22 is activated to complete the loading of the cylinder 40.

[0068] like Figures 7-8As shown: The lathe 3 includes a lathe body 32, a lathe headstock 33, and a tool post 37. There are two lathe headstocks 33 that are slidably mounted at both ends of the lathe body 32. The two lathe headstocks 33 are arranged facing each other. Each lathe headstock 33 is connected to a headstock pushing device, which makes the two lathe headstocks 33 move closer or further apart. There are also two tool posts 37 mounted on the lathe body 32. The tool posts 37 are arranged between the two lathe headstocks 33. The tool posts 37 are connected to a tool post feed device and a tool post translation device. The feed direction of the tool post feed device is perpendicular to the pushing direction of the headstock pushing device, and the translation direction of the tool post translation device is parallel to the pushing direction of the headstock pushing device. There are two lathe spindle boxes 33 and two tool posts 37. Both spindle boxes 33 are connected to spindle box pushers. The two spindle box pushers drive the two spindle boxes 33 to move, which enables the electric chucks 34 on the two spindle boxes 33 to cooperate and achieve tensioning at both ends of the cylinder 40. Each tool post 37 is connected to a tool post feed device and a tool post translation device, which enables the two tool posts 37 to turn the outer circle of the cylinder 40 from both ends of the cylinder 40, which greatly improves the turning speed of the outer circle of the cylinder 40.

[0069] A spindle box push guide 36 is installed on the top of the lathe body 32. The spindle box push guide 36 is horizontally arranged and has two parallel and spaced-apart spindle boxes 36. The lathe spindle boxes 33 are respectively located at both ends of the lathe body 32. Each lathe spindle box 33 is located on the upper side of the lathe body 32 and can be slidably mounted on the lathe body 32. The spindle box push device corresponds to each lathe spindle box 33. Each spindle box push device is mounted on the lathe body 32 and is connected to the lathe spindle box 33 on the corresponding side, and pushes the lathe spindle box 33 on the corresponding side to move along the spindle box push guide 36.

[0070] Each lathe spindle box 33 is equipped with a lathe spindle motor, which is connected to the lathe spindle of the lathe spindle box 33.
