Detailed implementation manners

[0030] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0031] Such as Figures 1 to 8As shown in the figure, a crankshaft processing turning equipment according to an embodiment of the present invention includes a lathe base 1; a fixed base 11 is fixedly connected to the top of the lathe base 1; a sliding base 12 is slidably connected to one side of the lathe base 1 away from the fixed base 11 through a first electric slider; a first servo motor is fixedly connected to one side of the fixed base 11 close to the sliding base 12; connecting shafts 13 are arranged on opposite sides of the fixed base 11 and the sliding base 12, and one connecting shaft 13 is fixedly connected to the output end of the first motor, and the other connecting shaft 13 is rotatably connected to one side of the sliding base 12 close to the fixed base 11; conical rods 14 are fixedly connected to opposite sides of the two connecting shafts 13; a fixed disk 15 is fixedly connected to the outer wall of the connecting shaft 13; a sliding frame 16 is slidably connected to the inner wall of the fixed disk 15; clamping plates 17 are slidably connected to the inner walls of the two sliding frames 16, and the two clamping plates 17 are arranged oppositely; a sliding component is arranged on the outer wall of the sliding frame 13; a turning tool component 18 is fixedly connected to the lathe base 1; a transmission component is arranged on the outer wall of the sliding frame 16, and the transmission component is used to assist the two clamping plates 17 to clamp and turn the crankshaft; when turning the crankshaft, taking the lathe base 1 as the main framework of the turning equipment, the sliding base 12 is driven by the first electric slider to slide close to the fixed base 11, and the crankshaft raw material is clamped on the two conical rods 14 between the two connecting shafts 13. The conical conical rods 14 can be more stably inserted into the holes at the ends of the crankshaft raw material. The sliding component controls the sliding frame 16 to slide on the fixed disk 15. After the two clamping plates 17 reach the clamping position of the turned crank arm of the crankshaft, and the two clamping plates 17 are located on the side of the position where the crankpin is to be turned out of the crankshaft raw material, at this time, the transmission component controls the two clamping plates 17 to clamp the crank arm of the crankshaft relatively. After multi-directional clamping is stable, the output end of the first servo motor on the fixed base 11 drives the clamped crankshaft raw material to rotate, and the turning tool component 18 turns out the crankpin on the rotating crankshaft. After one crankpin is turned, the turning tool component 18 then moves to the turning position, and the sliding component synchronously drives the two clamping plates 17 that release the clamping of the crank arm to slide, so that the two clamping plates 17 are located on the side of the next crankpin turning position. The transmission component drives the two clamping plates 17 to clamp the crank arm, and the turning tool component 18 continues to turn the crank raw material. The sliding frame 16 also drives the two clamping plates 17 to rotate synchronously with the crankshaft raw material, and can adaptively adjust the clamping position of the crank arm according to the current turning position, so as to keep the crankshaft stable during turning. The turning tool component 18 is the entire turning tool structure in the current technology and can be freely adjusted for turning work. After clamping the two ends of the crankshaft raw material by the two conical rods 14, according to the current turning position, the four clamping plates 17 are respectively clamped at the crank walls on both sides of the turning position, replacing the traditional method of only clamping the two ends of the crankshaft. It can adaptively adjust the clamping position to clamp both sides of the turning position, improve the clamping stability of the eccentric crankshaft, reduce the situation of the crankshaft falling off, improve the processing quality and the safety of the equipment, and reduce the failure rate and maintenance cost during the production process.

[0032] The sliding assembly includes a square plate 2, a fixing frame 21, a mating block 22 and a clamping block 23; the two square plates 2 are rotatably connected to the connecting shaft 13, and one square plate 2 is fixedly connected to the outer wall of the fixed seat 11, and the other square plate 2 is fixedly connected to the outer wall of the sliding seat 12; the fixing frame 21 is fixedly connected to one side of the square plate 2 close to the conical rod 14; the mating block 22 is slidably connected to the bottom end of the fixing frame 21 through a second electric slider, and the mating block 22 is rotatably connected to the sliding frame 16; the clamping block 23 is fixedly connected to the clamping plate 17, and the two clamping blocks 23 are arranged oppositely, and the opposite sides of the two clamping blocks 23 are both arranged in a V shape; when turning the crankpin of the crankshaft, whenever the turning tool of the turning tool assembly 18 moves to the next turning position of the crankshaft, the second electric slider slides on the bottom end of the fixing frame 21 on the square plate 2, and the second electric slider synchronously drives the sliding frame 16 connected by the mating block 22 to slide to the just-completed turning position. The transmission assembly drives the clamping blocks 23 connected to the two clamping plates 17 to clamp the outer wall of the crankshaft. The V-shaped surfaces of the two clamping blocks 23 can more stably clamp the crank arm with an arc-shaped surface. When the connecting shaft 13 drives the crankshaft to rotate, the mating block 22 can cooperate with the outer wall of the sliding frame 16 to rotate, and the front end of the fixing frame 21 can also cooperate with the outer wall of the fixed disk 15 to rotate, so that the entire sliding frame 16 can rotate synchronously with the output end of the first servo motor, stably clamping the outer wall of the crankshaft during the turning process. At the same time, the two V-shaped clamping blocks 23 can adapt to the clamping of crank arms with different thicknesses. By clamping the crank arm of the crankshaft with the two V-shaped clamping blocks 23, the stability of the turning of the crankshaft is improved.

[0033] The transmission assembly includes a support frame 3, a frame 31, a second servo motor 32 and a rack frame 33; the support frame 3 is fixedly connected to the sliding frame 16; the frame 31 is fixedly connected to the support frame 3; the second servo motor 32 is fixedly connected to the frame 31, and a gear is fixedly connected to the output end of the second servo motor 32; the rack frame 33 is fixedly connected to the clamping plate 17, the clamping plate 17 is slidably connected to the support frame 3, and the teeth of the two rack frames 33 can mesh with the gear; when controlling the two clamping blocks 23 to clamp the crank arm of the crankshaft, the output end of the second servo motor 32 on the frame 31 rotates, synchronously driving the gear to mesh with the teeth of the two rack frames 33, realizing the sliding of the two rack frames 33 on the support frame 3 respectively, and synchronously driving the clamping blocks 23 on the two clamping plates 17 to clamp the crank arm of the crankshaft, playing a role in controlling the clamping of the crank arm of the crankshaft.

[0034] The outer wall of the support frame 3 is fixedly connected to two first fixing plates 4; a first rotating shaft 41 is rotatably connected to the first fixing plate 4; a circulation box 42 is fixedly connected to the top end of the first rotating shaft 41; a spray head 43 is fixedly connected to the circulation box 42; a connection assembly is arranged on the rack frame 33, and the connection assembly is used to adjust the spraying angle of the spray head 43; when clamping the outer wall of the crankshaft, the circulation box 42 is externally connected to a cutting fluid pipe. As the rack frame 33 drives the clamping plate 17 to slide, the connection assembly synchronously drives the first rotating shaft 41 on the first fixing plate 4 to rotate. After clamping the outer wall of the crankshaft, the spraying position of the spray head 43 is adjusted as the first rotating shaft 41 rotates. At this time, the spray head 43 is aligned with the turning position to be machined. The spray head 43 sprays in a range. As the crankshaft is turned, the externally connected cutting fluid pipe pumps cutting fluid to the spray head 43 to spray at the turning position, reducing the high temperature generated during turning, avoiding thermal deformation of the workpiece and thermal wear of the tool, washing away the chips, preventing chip accumulation from affecting the machining accuracy, protecting the crankshaft from rusting after machining, and improving the turning effect of the crankshaft.

[0035] The connection assembly includes a second fixing plate 5, a second rotating shaft 51 and a hinged rod 52; the second fixing plate 5 is fixedly connected to the outer wall of the rack frame 33 close to the first fixing plate 4; the second rotating shaft 51 is rotatably connected to the second fixing plate 5; the hinged rod 52 is fixedly connected between the first rotating shaft 41 and the second rotating shaft 51, and the hinged rod 52 is formed by hinging two rods. The rod on the second rotating shaft 51 is a long rod, and the rod on the first rotating shaft 41 is a short rod; when adjusting the spraying position of the spray head 43, as the rack frame 33 slides, the long rod on the second rotating shaft 51 pushes the short rod hinged on the first rotating shaft 41, so that the spraying position of the spray head 43 is freely adjusted according to the thickness of the clamped crank, playing a role in adapting to adjust the spraying position of the spray head 43 according to different thicknesses of the crank.

[0036] As Figures 1 to 3 , Figure 5 , Figure 6 As shown, a first collecting plate 6 is fixedly connected to the fixed seat 11; a second collecting plate 61 is fixedly connected to the sliding seat 12, and the second collecting plate 61 is arranged opposite to the first collecting plate 6; when turning the crankshaft, a large amount of waste chips and cutting waste liquid are easily generated during turning. The first collecting plate 6 is used in cooperation with the second collecting plate 61 and is fixed on the opposite sides of the fixed seat 11 and the sliding seat 12. When the two conical rods 14 clamp the crankshaft, the second collecting plate 61 slides along with the sliding seat 12 and approaches and fits the outer wall of the first collecting plate 6 to be spliced. The generated waste chips and cutting waste liquid are collected by the first collecting plate 6 and the second collecting plate 61, playing a role in collecting the waste liquid and waste chips.

[0037] The first collecting plate 6 and the second collecting plate 61 are provided with adapted slopes. When the chips and waste liquid generated by crankshaft turning fall into the first collecting plate 6 and the second collecting plate 61, the slopes on the first collecting plate 6 and the second collecting plate 61 are used to guide the waste liquid carrying the chips, so that the chips and waste liquid can flow down from the first collecting plate 6 into the second collecting plate 61 for temporary storage and waiting for collection, playing a role in guiding and collecting the chips and waste liquid.

[0038] A downward flow groove 7 is formed in the second collecting plate 61; a collecting groove 71 is formed in the lathe base 1 below the downward flow groove 7. When the chips and waste liquid are guided to the inside of the second collecting plate 61, the downward flow groove 7 is used to drain the waste liquid carrying the chips, and the chips and waste liquid both fall from the downward flow groove 7. A filter screen can be arranged in the collecting groove 71, and the chips and waste liquid falling into the collecting groove 71 are filtered and temporarily stored, playing a role in cleaning the chips and waste liquid.

[0039] Two rotating rods 8 are relatively rotatably connected to both the first collecting plate 6 and the second collecting plate 61; a shielding plate 81 is fixedly connected to the rotating rod 8; a handle 82 is fixedly connected to the outer wall of the shielding plate 81. When cutting fluid is sprayed on the turned crankshaft, the sprayed cutting fluid is likely to splash onto the equipment. By using the four rotating rods 8 to rotate relatively in pairs on both sides of the first collecting plate 6 and the second collecting plate 61, the shielding plate 81 is pulled and rotated along with the rotating rod 8 by holding the handle 82, so that each rotating rod 8 is provided with a shielding plate 81 to block the splashing of the sprayed cutting fluid. After the crankshaft turning is completed, the handle 82 is pulled again to lower the shielding plate 81, facilitating the taking of the crankshaft.

[0040] Fixing rods 9 are fixedly connected to both sides of the square plate 2 close to the fixing frame 21; a support block 91 is fixedly connected to the end of the fixing rod 9 away from the square plate 2, and the side of the support block 91 close to the shielding plate 81 is arc-shaped. When the two shielding plates 81 block the sprayed cutting fluid, the two fixing rods 9 on the square plate 2 are used to support the two support blocks 91 respectively, so that the support blocks 91 support the outer wall of the shielding plate 81 to limit the position of the shielding plate 81, so that the shielding plate 81 can stably block the splashing of the cutting fluid.

[0041] Working process: When turning the crankshaft, the lathe base 1 is used as the main framework of the turning equipment. The first electric slider drives the sliding seat 12 to slide close to the fixed seat 11, and the crankshaft raw material is clamped on the two conical rods 14 between the two connecting shafts 13. The conical conical rods 14 can be inserted more stably into the holes at the ends of the crankshaft raw material. The sliding assembly controls the sliding frame 16 to slide on the fixed disk 15. After the two clamping plates 17 reach the clamping position of the crank arm where the crankshaft has been turned, and the two clamping plates 17 are located on the side of the position where the crankpin is to be turned on the crankshaft raw material, at this time, the transmission assembly controls the two clamping plates 17 to clamp the crank arm of the crankshaft relatively. After the multi-directional clamping is stable, the output end of the first servo motor on the fixed seat 11 drives the clamped crankshaft raw material to rotate, and the turning tool assembly 18 turns out the crankpin on the rotating crankshaft. After one crankpin is turned, the turning tool assembly 18 then moves to the turning position, and the sliding assembly synchronously drives the two clamping plates 17 that release the clamping of the crank arm to slide, so that the two clamping plates 17 are located on the side of the next crankpin turning position. The transmission assembly drives the two clamping plates 17 to clamp the crank arm, and the turning tool assembly 18 continues to turn the crank raw material. The sliding frame 16 also drives the two clamping plates 17 to rotate synchronously with the crankshaft raw material, and can adaptively adjust the clamping position of the crank arm according to the current turning position, so as to keep the crankshaft stable during turning. The turning tool assembly 18 is the entire turning tool framework in the current technology and can be freely adjusted for turning work. After clamping the two ends of the crankshaft raw material by the two conical rods 14, according to the current turning position, the four clamping plates 17 are respectively clamped at the crank walls on both sides of the turning position, replacing the traditional method of only clamping the two ends of the crankshaft. It can adaptively adjust the clamping position to clamp both sides of the turning position, improve the clamping stability of the eccentric crankshaft, reduce the situation of the crankshaft falling off, improve the processing quality and the safety of the equipment, and reduce the failure rate and maintenance cost during the production process; when turning the crankpin of the crankshaft, whenever the turning tool of the turning tool assembly 18 moves to the next turning position of the crankshaft, the second electric slider slides at the bottom end of the fixed frame 21 on the square plate 2, and the second electric slider synchronously drives the sliding frame 16 connected with the matching block 22 to slide to the just-completed turning position. The transmission assembly drives the clamping blocks 23 connected with the two clamping plates 17 to clamp the outer wall of the crankshaft. The V-shaped surfaces of the two clamping blocks 23 can clamp the crank arm with an arc-shaped surface more stably. When the connecting shaft 13 drives the crankshaft to rotate, the matching block 22 can rotate in cooperation with the outer wall of the sliding frame 16, and the front end of the fixed frame 21 can also rotate in cooperation with the outer wall of the fixed disk 15, so that the entire sliding frame 16 can rotate synchronously with the output end of the first servo motor, stably clamping the outer wall of the crankshaft during the turning process. At the same time, the two V-shaped clamping blocks 23 can adapt to the clamping of crank arms of different thicknesses, and turning the crank arm of the crankshaft by the two V-shaped clamping blocks 23 improves the turning stability of the crankshaft;When controlling the clamping blocks 23 to clamp the crank arm of the crankshaft, the output end of the second servo motor 32 on the frame 31 rotates, synchronously driving the gear to mesh with the teeth of the two rack frames 33, so that the two rack frames 33 slide on the support frame 3 respectively, and synchronously driving the clamping blocks 23 on the two clamping plates 17 to clamp the crank arm of the crankshaft, playing a role in controlling and clamping the crank arm of the crankshaft; when clamping the outer wall of the crankshaft, the circulation box 42 is externally connected to the cutting fluid pipe. As the rack frame 33 drives the clamping plate 17 to slide, the connecting component synchronously drives the first rotating shaft 41 on the first fixing plate 4 to rotate. After clamping the outer wall of the crankshaft, the spraying position of the nozzle 43 is adjusted as the first rotating shaft 41 rotates. At this time, the nozzle 43 is aligned with the turning position to be machined. The nozzle 43 sprays in a range. As the crankshaft is turned, the externally connected cutting fluid pipe pumps the cutting fluid to the nozzle 43 to spray at the turning position, reducing the high temperature generated during turning, avoiding thermal deformation of the workpiece and thermal wear of the tool, washing away the chips, preventing chip accumulation from affecting the machining accuracy, protecting the crankshaft from rusting after machining, and improving the turning effect of the crankshaft; when adjusting the spraying position of the nozzle 43, as the rack frame 33 slides, the long rod on the second rotating shaft 51 pushes the short rod hinged on the first rotating shaft 41, so that the spraying position of the nozzle 43 is freely adjusted according to the thickness of the clamped crank, playing a role in adapting and adjusting the spraying position of the nozzle 43 according to different thicknesses of the crank.

[0042] When turning the crankshaft, a large amount of waste chips and cutting waste liquid are easily generated. The first collecting plate 6 and the second collecting plate 61 are fixed on the opposite sides of the fixed seat 11 and the sliding seat 12. When the two conical rods 14 clamp the crankshaft, the second collecting plate 61 slides close to and fits the outer wall of the first collecting plate 6 as the sliding seat 12 slides. The generated waste chips and cutting waste liquid are collected by the first collecting plate 6 and the second collecting plate 61, playing a role in collecting the waste liquid and waste chips; when the waste chips and waste liquid generated by the turning of the crankshaft fall into the first collecting plate 6 and the second collecting plate 61, the slopes on the first collecting plate 6 and the second collecting plate 61 are used to guide the waste liquid carrying the waste chips, so that the waste chips and waste liquid can flow down from the first collecting plate 6 into the second collecting plate 61 for temporary storage and waiting for collection, playing a role in guiding and collecting the waste chips and waste liquid; when the waste chips and waste liquid are guided into the second collecting plate 61, the opened downward flow groove 7 is used to drain the waste liquid carrying the waste chips. The waste chips and waste liquid both fall from the downward flow groove 7. A filter screen can be set in the collecting groove 71. The waste chips and waste liquid falling into the collecting groove 71 are filtered and temporarily stored, playing a role in cleaning the waste chips and waste liquid.

[0043] When using a cutting fluid to spray on a turned crankshaft, the sprayed cutting fluid is likely to splash onto the equipment. By using four rotating rods 8 that rotate relative to each other in pairs on both sides of the first collecting plate 6 and the second collecting plate 61, the baffle plate 81 is pulled by holding the handle 82 and adjusted as the rotating rod 8 rotates, so that a baffle plate 81 is installed on each rotating rod 8 to block the splashing cutting fluid. After the crankshaft turning is completed, the handle 82 is pulled again to lower the baffle plate 81, facilitating the taking of the crankshaft;

[0044] When the two baffle plates 81 block the sprayed cutting fluid, the two fixing rods 9 on the square plate 2 respectively support the two support blocks 91, so that the support blocks 91 support the outer wall of the baffle plate 81 to limit the position of the baffle plate 81, enabling the baffle plate 81 to stably block the splashing of the cutting fluid.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
