Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically to a precision machining system and process for optimizing CNC machine tool machining process decisions. Background Technology

[0002] CNC machine tools for processing sheet metal, or CNC sheet metal machine tools for short, are machine tools that use CNC technology to perform cutting, drilling, milling and other processing operations on sheet metal. They achieve automated processing of sheet metal by inputting processing information in digital form and having the movement of the machine tool controlled by a computer.

[0003] According to the patent titled "A CNC Machine Tool for Plate Machining and its Machining Method" (Patent Publication No.: CN115255975A, Patent Publication Date: 2022-11-01), the invention includes a machine bed with two columns mounted on it. A fixing component is provided between the columns and the machine bed. A crossbeam connects the two columns. A first servo motor is fixedly mounted on one side of the crossbeam. A first lead screw is rotatably connected to the crossbeam, and the first servo motor is connected to the first lead screw. This invention, through the use of a V-shaped locking block that cooperates with a support plate and a pressure rod, can simultaneously fix multiple plates to be processed, achieving simultaneous processing of multiple plates at once. This improves the speed of cutting rounded corners and enhances overall processing efficiency. By employing a first, second, and third lead screw to control the movement direction of the tool holder, crossbeam, and slide, the tool holder and the plate to be processed are automatically adjusted at multiple angles, improving processing quality and efficiency.

[0004] Based on the aforementioned existing technologies, the precision machining systems and processes of current CNC machine tool machining process decision optimization methods still have the following problems: when CNC machine tools process plates, the plates are often fixed on the machine tool by fixtures. However, when processing the other side of the plate, the plate needs to be re-clamped, which reduces production efficiency and increases labor intensity. Therefore, this invention provides a precision machining system and process for CNC machine tool machining process decision optimization methods. Summary of the Invention

[0009] Preferably, the clamping unit includes a clamping box fixedly installed at one end of a sliding column.

[0011] This invention also discloses a precision machining system based on a CNC machine tool machining process decision optimization method, comprising the following steps: S1: First, the plate is placed inside the sliding frame. At this time, the two cylinders are running, and the cylinders push the two sliding columns to move towards each other. The sliding columns drive the clamping unit to move synchronously. The plate is pressed against the pressure plate. The pressure plate pushes the sliding block through the connecting column. The sliding block slides inside the limiting slide groove. The sliding block drives the two linkage plates to move synchronously. While the linkage plates are moving, the two sliding columns slide inside the two inclined grooves. The two sliding columns drive the two moving rods to move towards each other, which in turn drives the two clamping blocks to move towards each other, thus clamping the plate. S2: Next, when the plate needs to be flipped after processing, the drive motor runs, driving the rotating rod to rotate clockwise. The rotating rod drives the two drive gears to rotate synchronously. The two drive gears mesh with the drive rack, causing the fixed plate and sliding frame to slide towards the front end of the base. At the same time, when the linkage gear moves to the tooth above the linkage rack, the tooth on the linkage rack meshes with the linkage gear, and the linkage gear rotates clockwise. The linkage gear drives the first pulley to rotate synchronously through the second pulley and belt. The first pulley drives the support rod to rotate synchronously. The support rod rotates to a vertical position to support the base and sliding frame. S3: Next, the two flipping motors operate, driving the two intermittent gears to operate. While the intermittent gears are rotating, the arc-shaped inclined block contacts the connecting rod. The connecting rod rotates through the connecting block to the connection point with the connecting seat, lifting the connecting rod and causing the insertion post to move out of the insertion hole. At this time, the intermittent gear drives the angle gear to rotate. The angle gear rotates 180 degrees, which drives the sliding column to rotate synchronously, driving the clamping unit to rotate synchronously. The clamping unit drives the plate to rotate synchronously 180 degrees. After that, the connecting rod disengages from the arc-shaped inclined block, and the reset unit pushes the connecting rod through its own elasticity, causing the insertion post to insert into another insertion hole to limit the angle gear. S4: Then, the drive motor runs in reverse, causing the sliding frame to slide above the base. The sliding frame slides towards the rear end of the base, and at the same time, the linkage gear rotates in reverse through the linkage rack, driving the support rod to rotate in reverse. The support rod contacts the top of the limit block, making the support rod horizontal, and the plate is reset for processing.

[0012] Preferably, in step S3, the limiting component operates to limit the angle gear after the angle gear rotates 180 degrees.

[0013] This invention provides a precision machining system and process for optimizing CNC machine tool machining processes. Compared with existing technologies, it has the following advantages: 1. The precision machining system and process of this CNC machine tool machining process decision optimization method involves two cylinders that drive two sliding columns to move in opposite directions. The sliding columns drive the clamping unit to move synchronously, clamping and fixing the workpiece. Two flipping motors drive two intermittent gears, which in turn drive angle gears to rotate 180 degrees. The angle gears drive the sliding columns to rotate synchronously, which in turn drive the clamping unit to rotate synchronously. The clamping unit then drives the workpiece to rotate 180 degrees synchronously, thus achieving the flipping of the workpiece. This allows for reverse machining of the workpiece without the need for re-clamping or adjustment, improving production efficiency and reducing labor intensity.

[0014] 2. The precision machining system and process of the CNC machine tool machining process decision optimization method, in which the arc-shaped inclined block contacts the connecting rod while the intermittent gear rotates, the connecting rod rotates through the connecting block to the connection point with the connecting seat, the connecting rod is lifted, and the insert is moved out of the insertion hole. At this time, the intermittent gear drives the angle gear to rotate 180 degrees. Then the connecting rod disengages from the arc-shaped inclined block, and the reset unit pushes the connecting rod through its own elasticity, so that the insert is inserted into another insertion hole, thereby limiting the angle gear, keeping the plate in a horizontal state, and preventing the plate from rotating due to its weight; 3. The precision machining system and process of the CNC machine tool machining process decision optimization method: The plate is placed inside the sliding frame. At this time, two cylinders are running, and the cylinders push two sliding columns to move towards each other. The sliding columns drive the clamping unit to move synchronously. The plate is pressed against the pressure plate. The pressure plate pushes the sliding block through the connecting column. The sliding block slides inside the limit slide groove. The sliding block drives two linkage plates to move synchronously. At the same time as the linkage plates move, the two sliding columns slide inside the two inclined grooves. The two sliding columns drive two moving rods to move towards each other, and drive the two clamping blocks to move towards each other, clamping the front, back, left and right sides of the plate, thereby preventing the plate from shifting due to its weight when it is rotated and flipped.

[0018] Please see Figure 1-11 The present invention provides a technical solution: A precision machining system for CNC machine tool machining process decision optimization method includes a machining mechanism 1. The machining mechanism 1 has a flipping mechanism 2 inside for flipping the sheet metal. The flipping mechanism 2 includes: The rotating unit 21, located inside the processing mechanism 1, includes a base 211.

A cylinder 2112 is fixedly mounted on one side of the cylinder frame 2111. Motor mounting plates 2113 are fixedly mounted on both the front and rear sides of the top of the sliding frame 212. A tilting motor 2114 is fixedly mounted on one side of the motor mounting plate 2113, and the output end of the tilting motor 2114 passes through the motor mounting plate 211. 3. An intermittent gear 2115 is fixedly installed. Angle gears 2116 are rotatably installed inside the front and rear plates of the sliding frame 212. A limit hole 2118 is opened inside the angle gear 2116. Two insertion holes 2110 are symmetrically opened inside the angle gear 2116. A sliding column 2117 is slidably installed inside the limit hole 2118. The output end of the cylinder 2112 passes through the cylinder frame 2111 and is rotatably connected to the sliding column 2117. A limit component 3 is provided on the side of the motor fixing plate 2113 near the intermittent gear 2115. The rotating unit 21 also includes two I-shaped blocks 213 fixedly installed at the bottom of the base 211. A U-shaped frame 214 is fixedly installed at the bottom of the I-shaped blocks 213. A drive motor 215 is fixedly installed on the left side of the U-shaped frame 214. A rotating rod 216 is rotatably installed inside the U-shaped frame 214 and passes through the two I-shaped blocks 213. The output end of the drive motor 215 passes through the U-shaped frame 214 and is fixedly connected to the rotating rod 216. Two drive gears 217 are fixedly installed on the surface of the rotating rod 216. Fixing plates 218 are fixedly installed on both the left and right sides of the sliding frame 212. A drive rack 219 is fixedly installed at the bottom of the fixing plate 218, and the drive gears 217 and the drive rack 219 are meshed together. Two cylinders 2112 operate, pushing two sliding columns 2117 to move towards each other. The sliding columns 2117 drive the clamping unit 23 to move synchronously, clamping and fixing the plate. Two flipping motors 2114 operate, driving two intermittent gears 2115 to operate. The intermittent gears 2115 drive the angle gear 2116 to rotate. The angle gear 2116 rotates 180 degrees, driving the sliding columns 2117 to rotate synchronously, driving the clamping unit 23 to rotate synchronously. The clamping unit 23 drives the plate to rotate 180 degrees synchronously, thus realizing the flipping of the plate. This allows for reverse processing of the plate without re-clamping or adjustment, improving production efficiency and reducing labor intensity.

[0019] Support units 22 are disposed on the left and right sides of the sliding frame 212 and are used to support the rotating unit 21. They include two mounting blocks 222 fixedly installed on the left and right sides of the sliding frame 212. A first pulley 223 is rotatably mounted on one side of the mounting block 222 via a rotating shaft. A support rod 224 is fixedly mounted on one side of the first pulley 223, and a pulley 225 is rotatably mounted on one end of the support rod 224. A second pulley 226 is rotatably mounted on both the left and right sides of the sliding frame 212 via a rotating shaft. A linkage gear 227 is fixedly mounted on one side of the second pulley 226. A linkage rack 221 is fixedly mounted on the top of the fixed plate 218, and the linkage gear 227 is meshed with the linkage rack 221. The second pulley 226 and the first pulley 223 are connected by a belt 229. Limit blocks 228 are fixedly mounted on both the left and right sides of the sliding frame 212. The rotating unit 21 has a symmetrical front and rear structure. At the same time, the two flipping motors 2114 run in opposite directions. The fixed plate 218 and the sliding frame 212 slide towards the front end of the base 211. At the same time, when the linkage gear 227 moves to the tooth above the linkage rack 221, the tooth on the linkage rack 221 meshes with the linkage gear 227, and the linkage gear 227 rotates clockwise. The linkage gear 227 drives the first pulley 223 to rotate synchronously through the second pulley 226 and the belt 229. The first pulley 223 drives the support rod 224 to rotate synchronously. The support rod 224 rotates to a vertical state to support the base 211 and the sliding frame 212, thereby preventing the base 211 and the sliding frame 212 from falling due to the weight of the plate.

[0020] The clamping unit 23 is disposed at one end of the sliding column 2117 and is used to clamp and fix the plate.

[0021] In this embodiment, the limiting component 3 includes a connecting seat 31 fixedly installed on the side of the motor fixing plate 2113 near the intermittent gear 2115. A connecting block 32 is hinged to one end of the connecting seat 31. A connecting rod 36 is fixedly installed at the bottom of the connecting block 32. A rectangular groove 33 is opened inside the connecting rod 36. A sliding rod 34 is fixedly installed on the side of the motor fixing plate 2113 near the intermittent gear 2115.

The plug 38 slides into the interior of the insertion hole 2110.

[0022] While the intermittent gear 2115 rotates, the arc-shaped inclined block 37 contacts the connecting rod 36. The connecting rod 36 rotates through the connecting block 32 at the connection point with the connecting seat 31, lifting the connecting rod 36 and causing the insertion post 38 to move out of the insertion hole 2110. At this time, the intermittent gear 2115 drives the angle gear 2116 to rotate 180 degrees. Then, the connecting rod 36 disengages from the arc-shaped inclined block 37, and the reset unit 35 pushes the connecting rod 36 through its own elasticity, causing the insertion post 38 to be inserted into another insertion hole 2110, thereby limiting the angle gear 2116 and keeping the plate in a horizontal state to prevent the plate from rotating due to its weight. In this embodiment, the clamping unit 23 includes a clamping box 231 fixedly installed at one end of the sliding column 2117. The clamping box 231 has a limiting groove 232 inside, and a sliding block 233 is slidably installed inside the limiting groove 232.

A connecting column 239 is fixedly installed on one side of the sliding block 233, and a pressure plate 2310 is fixedly installed through the clamping box 231 at one end.

[0023] Two clamping units 23 are provided at one end of each of the two sliding columns 2117. The two clamping units 23 are symmetrical in front and back and symmetrical in left and right. When the plate is placed inside the sliding frame 212, the two cylinders 2112 are activated. The cylinders 2112 push the two sliding columns 2117 to move towards each other. The sliding columns 2117 drive the clamping units 23 to move synchronously. The plate squeezes the pressure plate 2310. The pressure plate 2310 pushes the sliding block 233 through the connecting column 239. The sliding block 233 slides inside the limiting slide groove 232. The sliding block 233 drives the two linkage plates 234 to move synchronously. While the linkage plates 234 are moving, the two sliding columns 237 slide inside the two inclined grooves 235. The two sliding columns 237 drive the two moving rods 236 to move towards each other and drive the two clamping blocks 238 to move towards each other, clamping the front, back, left and right sides of the plate, thereby preventing the plate from shifting due to its weight when it is rotated and flipped.

[0026] This invention also discloses a precision machining system based on a CNC machine tool machining process decision optimization method, comprising the following steps: S1: First, the plate is placed inside the sliding frame 212. At this time, the two cylinders 2112 are running. The cylinders 2112 push the two sliding columns 2117 to move towards each other. The sliding columns 2117 drive the clamping unit 23 to move synchronously. The plate squeezes the pressure plate 2310. The pressure plate 2310 pushes the sliding block 233 through the connecting column 239. The sliding block 233 slides inside the limiting slide groove 232. The sliding block 233 drives the two linkage plates 234 to move synchronously. While the linkage plates 234 are moving, the two sliding columns 237 slide inside the two inclined grooves 235. The two sliding columns 237 drive the two moving rods 236 to move towards each other, and drive the two clamping blocks 238 to move towards each other to clamp the plate.

The two drive gears 217 mesh with the drive rack 219, driving the fixed plate 218 and the sliding frame 212 to slide towards the front end of the base 211. At the same time, when the linkage gear 227 moves to the teeth above the linkage rack 221, the teeth on the linkage rack 221 mesh with the linkage gear 227, and the linkage gear 227 rotates clockwise. The linkage gear 227 drives the first pulley 223 to rotate synchronously through the second pulley 226 and the belt 229. The first pulley 223 drives the support rod 224 to rotate synchronously. The support rod 224 rotates to a vertical state to support the base 211 and the sliding frame 212. S3: Next, the two flipping motors 2114 operate, driving the two intermittent gears 2115 to operate. While the intermittent gears 2115 are rotating, the arc-shaped inclined block 37 contacts the connecting rod 36. The connecting rod 36 rotates through the connecting block 32 to the connection point with the connecting seat 31, lifting the connecting rod 36 and causing the insertion post 38 to move out of the insertion hole 2110. At this time, the intermittent gear 2115 drives the angle gear 2116 to rotate. The angle gear 2116 rotates 180 degrees, and the angle gear 2116 drives the sliding column 2117 to rotate synchronously, driving the clamping unit 23 to rotate synchronously. The clamping unit 23 drives the plate to rotate 180 degrees synchronously. After that, the connecting rod 36 disengages from the arc-shaped inclined block 37, and the reset unit 35 pushes the connecting rod 36 through its own elasticity, causing the insertion post 38 to be inserted into another insertion hole 2110 to limit the angle gear 2116. S4: Then, the drive motor 215 runs in reverse, causing the sliding frame 212 to slide above the base 211. The sliding frame 212 slides towards the rear end of the base 211. At the same time, the linkage gear 227 rotates in reverse through the linkage rack 221, driving the support rod 224 to rotate in reverse. The support rod 224 contacts the top of the limit block 228, making the support rod 224 horizontal. The plate is then reset for processing.

[0027] In this embodiment, in step S3, after the angle gear 2116 rotates 180 degrees, the limiting component 3 operates to limit the angle gear 2116.
