Description

Technical Field

[0001] The present invention relates to the technical field of CNC machining centers, and specifically to a CNC machining center positioning and cutting device provided with a fine-tuning component. Background Technique

[0002] CNC machining generally refers to computer numerical control precision machining, such as CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. The feed machining route of a CNC lathe refers to the path that the turning tool travels from the tool setting point until it returns to that point and ends the machining program, including the path of cutting machining and non-cutting idle stroke paths such as tool entry and exit.

[0003] For example, the patent with the publication number CN213702572U discloses a sheet cutting device for CNC fixtures production. This patent can clamp the steel to be cut through the setting of a fixing device, and the first threaded rod and the second threaded rod can fix the steel clamped inside the fixing device in the left-right direction, while the fourth threaded rod and the pressing plate can limit and fix the steel in the up-down direction. However, in the actual use process of this type of device, the position during cutting is adjusted by rotating the third threaded rod with the second turning handle. Therefore, when the thread pitch on the outer side of the threaded rod is small, although the accuracy during adjustment can be improved, the overall time consumption is long when moving the cutting tool position over a large distance. And when the thread pitch on the outer side of the threaded rod is large, although the moving speed of the cutting tool can be increased, it is not convenient to accurately control the cutting position due to the reduced accuracy, resulting in certain limitations in use.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a CNC machining center positioning and cutting device provided with a fine-tuning component is proposed. Summary of the Invention

The top of the fixed cylinder is connected to the second one-way valve, and the oil injection pipe is arranged on the top of the second one-way valve and is fixedly connected to the fixed box.

[0012] Further, one end of the drive shaft is connected to a telescopic assembly. The telescopic assembly includes a fixed disk, an adjustment plate, and a limiting groove.

A second moving seat is threadedly connected to the middle outside of the second screw rod, and a loading platform is arranged on the top of the second moving seat.

[0016] The present invention provides a CNC machining center positioning and cutting device provided with a fine adjustment assembly, having the following beneficial effects:

[0017] 1. When the present invention adjusts the cutting position by controlling the position of the first moving seat, the rotating disk can be rotated first according to requirements. Since the horizontal long hole on the side of the fixed box limits the moving direction of the sliding rod through the slider, the sliding rod can be pushed through the guiding groove to move horizontally, so as to drive the driving ring to move through the adjusting sleeve, making the first ratchet disk engage with the second ratchet disk. Therefore, during the rotation of the drive shaft, the first screw rod can be driven to rotate through the driving ring, the first ratchet disk, the second ratchet disk, the driving gear, and the triple gear shaft to adjust the position of the first moving seat. At the same time, the number of driving gears is set to be multiple and their sizes are different. Therefore, during use, only by controlling the engagement of the first ratchet disk with the corresponding second ratchet disk, the rotation speed of the first screw rod can be controlled, so that during use, it is convenient to quickly move the position of the first moving seat or perform fine adjustment when calibration is required.

[0018] 2. There are two types of guiding grooves in the present invention. When the fixing plate is horizontal, one of the driving rings drives the first ratchet disc to engage with the second ratchet disc on the driving gear in the middle. When the fixing plate rotates counterclockwise, the original driving ring drives the first ratchet disc on the other side to engage with the second ratchet disc on the larger driving gear, and the other slide bar slides within the arc portion of the guiding groove without changing its position. And when the fixing plate rotates clockwise, the original driving ring moves between the two driving gears, and the first ratchet disc on the other driving ring docks with the second ratchet disc on the smaller driving gear. And before adjustment, just pinch the pressing plate and the fixing plate. At this time, the pressing plate presses the limiting block, causing the plug pin to separate from the fixing ear. After releasing the hand after rotating the fixing plate, the spring seat pushes the limiting block, causing the plug pin to insert into the fixing ear, and the position of the rotating disc can be automatically locked, thereby improving the convenience during multi-stage adjustment.

[0019] 3. Before using the present invention, some lubricating oil can be injected into the lower end of the fixing box. During the rotation of the triple gear shaft, the limiting ring is driven to rotate through the synchronous gear, thereby squeezing the piston rod, so that the lubricating oil inside the fixing cylinder is ejected from the oil spraying pipe through the second one-way valve to lubricate the gears below, thereby extending the service life. And when the piston rod moves to the thin part of the limiting ring, the return spring pushes the piston rod, and the lubricating oil at the lower part of the fixing box can be sucked into the fixing cylinder through the oil suction pipe automatically through the first one-way valve for replenishment. And the filter cover is also used to block the impurity particles carried in the oil fluid to avoid the impurity particles adhering to the gears again and aggravating the wear of the gears.

[0020] 4. When the present invention uses the acceleration structure to quickly move the position of the first moving seat, the rotating plate can be pressed with the thumb, so that the sliding column drives the vertical rod to move upward, and then the connecting rod is used to pull the clamping block to retract it into the adjusting plate, and the restriction between the adjusting plate and the fixing plate can be quickly released. After moving the adjusting plate upward and releasing the rotating plate, the torsion spring can drive the rotating plate to reset at this time. Similarly, the clamping block will insert into the limiting groove in the fixing plate, and the fixing between the adjusting plate and the fixing plate can be quickly carried out. Therefore, during adjustment, the force arm during adjustment can be extended, thereby avoiding the situation that it is more laborious to rotate the driving shaft due to the acceleration structure.

Detailed implementation manners

[0030] Please refer to Figures 1 to 8, the present invention provides a technical solution: a CNC machining center positioning and cutting device provided with a fine-tuning component, including a frame 1 and an adjustment component 9. An electric push rod 2 is arranged inside the upper end of the frame 1, and a cutting machine 3 is connected to the bottom of the electric push rod 2. An adjustment seat 4 is arranged in the middle of the frame 1, and a fixed box 5 is arranged at one end of the adjustment seat 4. A triple gear shaft 6 is rotatably connected inside the fixed box 5, and a driving gear 7 is engaged with one side of the triple gear shaft 6. And a driving shaft 8 is rotatably connected inside the driving gear 7. The adjustment component 9 is arranged outside the driving shaft 8. The adjustment component 9 includes a rotating disk 901, a guiding groove 902, a sliding rod 903, a sliding block 904, an adjustment sleeve 905, a driving ring 906, a first ratchet disk 907 and a second ratchet disk 908. A guiding groove 902 is opened on one side of the rotating disk 901, and a sliding rod 903 is slidably connected inside the guiding groove 902. A sliding block 904 is fixed on the outer side of the middle part of the sliding rod 903, and the sliding block 904 is slidably connected with the fixed box 5. An adjustment sleeve 905 is fixed at the end of the sliding rod 903, and a driving ring 906 is rotatably connected inside the adjustment sleeve 905. The driving ring 906 is slidably connected with the driving shaft 8, and a first ratchet disk 907 is fixed on one side of the driving ring 906. A second ratchet disk 908 is connected to one side of the driving gear 7.

[0031] Please refer to Figures 1 to 6 , a positioning component 10 is arranged on one side of the rotating disk 901. The positioning component 10 includes a fixing plate 1001, a spring seat 1002, a limiting block 1003 and a plug pin 1004. A fixing plate 1001 is arranged on one side of the rotating disk 901, and a spring seat 1002 is arranged at one end of the top of the fixing plate 1001. A limiting block 1003 is connected to one side of the spring seat 1002, and a plug pin 1004 is fixed on one side of the limiting block 1003. The positioning component 10 further includes a fixing ear 1005, a limiting sleeve 1006, a telescopic column 1007 and a pressing plate 1008. A fixing ear 1005 is slidably connected to the outer side of one end of the plug pin 1004, and a limiting sleeve 1006 is arranged on one side of the fixing ear 1005. The limiting sleeve 1006 is rotatably connected with the rotating disk 901, and the limiting sleeve 1006 is fixedly connected with the fixed box 5. Telescopic columns 1007 are arranged at both ends of the top of the fixing plate 1001, and a pressing plate 1008 is fixed at the top of the telescopic columns 1007;

[0032] The specific operation is as follows: Hold the pressing plate 1008 and the fixing plate 1001. At this time, the pressing plate 1008 will squeeze the limiting block 1003, causing the bolt 1004 to separate from the fixing ear 1005. Then, rotate as needed to make the rotating disk 901 rotate. Since the horizontal long hole on the side of the fixed box 5 will limit the moving direction of the sliding rod 903 through the slider 904, the sliding rod 903 can be pushed through the guiding groove 902 to move horizontally. When the fixing plate 1001 is horizontal, one driving ring 906 will drive the first ratchet disk 907 to engage with the second ratchet disk 908 on the middle driving gear 7. When the fixing plate 1001 rotates counterclockwise, the original driving ring 906 will drive the first ratchet disk 907 on the other side to engage with the second ratchet disk 908 on the larger driving gear 7, while the other sliding rod 903 will slide within the arc part of the guiding groove 902 without changing its position. When the fixing plate 1001 rotates clockwise, the original driving ring 906 will move between the two driving gears 7, and the first ratchet disk 907 on the other driving ring 906 will be docked with the second ratchet disk 908 on the smaller driving gear 7. Therefore, during use, by simply controlling the engagement of the first ratchet disk 907 with the corresponding second ratchet disk 908, the rotation speed of the triple gear shaft 6 can be controlled, so that during use, it is convenient to quickly move the position of the workpiece or finely adjust the position of the workpiece when calibration is required. Then, after releasing the hand after rotating the fixing plate 1001, the spring seat 1002 will push the limiting block 1003, causing the bolt 1004 to insert into the fixing ear 1005, and the position of the rotating disk 901 can be automatically locked, thereby improving the convenience during multi-level adjustment. After that, during the rotation of the drive shaft 8, the triple gear shaft 6 is driven to rotate through the driving ring 906, the first ratchet disk 907, the second ratchet disk 908, and the driving gear 7 to adjust the position of the workpiece.

[0033] Please refer to Figures 1 to 4 、 Figure 7 and Figure 8, a lubrication component 11 is arranged inside the fixed box 5. The lubrication component 11 includes a synchronous gear 1101, a limit ring 1102, a piston rod 1103 and a return spring 1104. The synchronous gear 1101 is rotatably connected inside the fixed box 5 and meshes with the triple gear shaft 6. A limit ring 1102 is arranged on one side of the synchronous gear 1101, and a piston rod 1103 is slidably connected to one side of the limit ring 1102. A return spring 1104 is connected to one side of the piston rod 1103. The lubrication component 11 further includes a fixed cylinder 1105, a first one-way valve 1106, an oil suction pipe 1107 and a filter cover 1108. The fixed cylinder 1105 is slidably connected to the outside of the piston rod 1103 and is fixedly connected to the fixed box 5. The first one-way valve 1106 is arranged at the bottom of the fixed cylinder 1105, and the oil suction pipe 1107 is connected to the bottom of the first one-way valve 1106. A filter cover 1108 is arranged on the outer side of the lower end of the oil suction pipe 1107. The lubrication component 11 further includes a fixed cylinder 1105, a first one-way valve 1106, an oil suction pipe 1107 and a filter cover 1108. The fixed cylinder 1105 is slidably connected to the outside of the piston rod 1103 and is fixedly connected to the fixed box 5. The first one-way valve 1106 is arranged at the bottom of the fixed cylinder 1105, and the oil suction pipe 1107 is connected to the bottom of the first one-way valve 1106. A filter cover 1108 is arranged on the outer side of the lower end of the oil suction pipe 1107. One end of the drive shaft 8 is connected to a telescopic component 12. The telescopic component 12 includes a fixed disk 1201, an adjusting plate 1202 and a limit groove 1203. A fixed disk 1201 is arranged at one end of the drive shaft 8, and the adjusting plate 1202 is slidably connected inside the fixed disk 1201. Limit grooves 1203 are arranged on both sides inside the fixed disk 1201. The telescopic component 12 further includes a rotating plate 1204, a torsion spring 1205 and a sliding column 1206. One end of the adjusting plate 1202 is rotatably connected to the rotating plate 1204, and torsion springs 1205 are fixed on both sides of the rotating plate 1204 and are fixedly connected to the adjusting plate 1202. A sliding column 1206 is slidably connected inside one end of the rotating plate 1204. The telescopic component 12 further includes a vertical rod 1207, a connecting rod 1208 and a clamping block 1209. A vertical rod 1207 is fixed in the middle of the sliding column 1206 and is slidably connected to the adjusting plate 1202. The bottom of the vertical rod 1207 is rotatably connected to the connecting rod 1208, and the clamping blocks 1209 are rotatably connected to both sides of the connecting rod 1208 and are slidably connected to the adjusting plate 1202. A first screw rod 13 is rotatably connected inside the adjusting seat 4 and is fixedly connected to the triple gear shaft 6. A first moving seat 14 is threadedly connected to the outside of the first screw rod 13. A motor 15 is arranged on one side of the first moving seat 14, and a second screw rod 16 is connected to one end of the motor 15. A second moving seat 17 is threadedly connected to the middle outer side of the second screw rod 16, and a carrier table 18 is arranged on the top of the second moving seat 17;

[0034] The specific operation is as follows. When holding the handle at the end of the adjusting plate 1202 to drive the driving shaft 8 to rotate by the fixed disk 1201, the rotating plate 1204 can be pressed by the thumb at the same time, so that the sliding column 1206 drives the vertical rod 1207 to move upward, and then the clamping block 1209 is pulled by the connecting rod 1208 to retract into the adjusting plate 1202, so that the restriction between the adjusting plate 1202 and the fixed disk 1201 can be quickly released. After the adjusting plate 1202 is moved upward, the rotating plate 1204 is released. At this time, the torsion spring 1205 can drive the rotating plate 1204 to reset. Similarly, the clamping block 1209 will be inserted into the limiting groove 1203 in the fixed disk 1201, so that the adjusting plate 1202 and the fixed disk 1201 can be quickly fixed. Therefore, during adjustment, the force arm during adjustment can be extended. When the driving shaft 8 drives the triple gear shaft 6 to rotate through the driving ring 906, the first ratchet disk 907, the second ratchet disk 908 and the driving gear 7, the limiting ring 1102 will also be driven to rotate by the synchronous gear 1101, thereby squeezing the piston rod 1103, so that the lubricating oil in the fixed cylinder 1105 will be sprayed out from the oil spraying pipe 1110 through the second one-way valve 1109 to lubricate the lower gears, thus extending the service life. And when the piston rod 1103 moves to the thin part of the limiting ring 1102, the return spring 1104 will push the piston rod 1103, and the oil suction pipe 1107 can suck the lubricating oil at the lower part of the fixed box 5 into the fixed cylinder 1105 for automatic replenishment through the first one-way valve 1106. And the filter cover 1108 is also used to block the impurity particles carried in the oil fluid to prevent the impurity particles from adhering to the gears again and aggravating the wear of the gears. After that, when the triple gear shaft 6 drives the first screw rod 13 to rotate, the position of the first moving seat 14 can be controlled. Subsequently, the electric push rod 2 drives the cutting machine 3 to move downward, and at the same time, the motor 15 drives the second screw rod 16 to rotate, so that the second moving seat 17 can move to cut the workpiece.

[0035] In summary, for the positioning and cutting equipment of a CNC machining center with a fine-tuning component, during use, first, place the workpiece on the carrier table 18. At the same time, multiple mounting holes are provided on the carrier table 18 to facilitate the installation of corresponding fixtures to fix the workpiece. Secondly, pinch the pressure plate 1008 and the fixed plate 1001. At this time, the pressure plate 1008 will squeeze the limit block 1003, causing the plug pin 1004 to separate from the fixed ear 1005. Then, rotate the rotating disk 901 as needed. Since the horizontal long hole on the side of the fixed box 5 will limit the moving direction of the slide bar 903 through the slider 904, the slide bar 903 can be pushed through the guide groove 902 to move horizontally. And when the fixed plate 1001 is in a horizontal state, the adjusting sleeve 905 will cause one of the driving rings 906 to drive the first ratchet disk 907 to engage with the second ratchet disk 908 on the driving gear 7 in the middle. When the fixed plate 1001 rotates counterclockwise, the original driving ring 906 will drive the first ratchet disk 907 on the other side to engage with the second ratchet disk 908 on the larger driving gear 7, while the other slide bar 903 will slide within the arc portion of the guide groove 902 without changing its position. And when the fixed plate 1001 rotates clockwise, the original driving ring 906 will move between the two driving gears 7, and the first ratchet disk 907 on the other driving ring 906 will be butted against the second ratchet disk 908 on the smaller driving gear 7. Then, after releasing the hand after rotating the fixed plate 1001, the spring seat 1002 will push the limit block 1003, causing the plug pin 1004 to insert into the fixed ear 1005, and the position of the rotating disk 901 can be automatically locked, thus improving the convenience during multi-stage adjustment. After that, hold the handle at the end of the adjusting plate 1202, so that when the fixed disk 1201 drives the driving shaft 8 to rotate, the first screw 13 can be driven through the driving ring 906, the first ratchet disk 907, the second ratchet disk 908, the driving gear 7 and the triple gear shaft 6 to adjust the position of the first moving seat 14. Since multiple driving gears 7 are provided and their sizes are different, during use, only by controlling the engagement of the first ratchet disk 907 with the corresponding second ratchet disk 908 can the rotation speed of the first screw 13 be controlled. Then, when quickly moving the position of the first moving seat 14 by using the acceleration structure, the rotating plate 1204 can be pressed with the thumb, so that the sliding column 1206 drives the vertical rod 1207 to move upward, and then the connecting rod 1208 is used to pull the clamping block 1209 to retract it into the adjusting plate 1202, and the restriction between the adjusting plate 1202 and the fixed disk 1201 can be quickly released. And after moving the adjusting plate 1202 upward and releasing the rotating plate 1204, the torsion spring 1205 can drive the rotating plate 1204 to reset at this time. Similarly, the clamping block 1209 will insert into the limiting groove 1203 in the fixed disk 1201, and the adjustment plate 1202 and the fixed disk 1201 can be quickly fixed. Therefore, during adjustment, the lever arm during adjustment can be extended, making the adjustment more labor-saving. Then,During the rotation of the triple gear shaft 6, the limit ring 1102 is also driven to rotate through the synchronizing gear 1101, thereby squeezing the piston rod 1103, so that the lubricating oil inside the fixed cylinder 1105 is ejected from the oil spray pipe 1110 through the second one-way valve 1109 to lubricate the lower gears, thus extending the service life. And when the piston rod 1103 moves to the thin part of the limit ring 1102, the return spring 1104 will push the piston rod 1103, and the oil suction pipe 1107 can suck the lubricating oil at the lower part of the fixed box 5 into the fixed cylinder 1105 for automatic replenishment through the first one-way valve 1106. In addition, the filter cover 1108 is used to block the impurity particles carried in the oil. Finally, after moving the first moving seat 14 to the designated position, the electric push rod 2 drives the cutting machine 3 to move downwards, and at the same time, the motor 15 drives the second screw rod 16 to rotate, so that the second moving seat 17 can move, thereby automatically cutting the workpiece.
