Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and specifically to a cutting equipment and a cutting method for machining automotive parts. Background Art

[0002] Cutting machining is one of the most basic and widely used machining methods in the manufacturing industry. Its core is to remove excess material in the form of chips through the relative movement between the cutting tool and the workpiece, so that the workpiece meets the design requirements. Cutting equipment is used for cutting machining when machining automotive parts;

[0003] Chinese Patent CN118342036B discloses a cutting device for machining automotive parts. By pulling out the insertion column from the inside of the slot, the rotational kinetic energy provided by the driving shaft to the driven shaft disappears, causing the cutting blade to gradually decelerate and stop. By driving the second displacement block to move closer to the driven shaft, the locking column is locked inside the locking groove, prompting the driven shaft to make an emergency stop, causing the cutting blade to be emergently braked under its action, improving the safety during the cutting process. However, in the prior art, when cutting a workpiece, the cutting depth of the cutting blade is constant. In actual production, different workpieces require different cutting depths. The constant cutting depth cannot meet the processing requirements of various workpieces, and the chips generated during the cutting process will inevitably stick to substances such as engine oil, thus having adhesiveness. When the chips fall onto the guide plate, they will adhere to the guide plate and are difficult to clean. Summary of the Invention

Specific embodiments

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1;

[0029] Please refer to Figures 1-8, a cutting device, comprising a machine tool 1 and a cutting groove 11 formed in the machine tool 1. A cutting assembly 2, a cleaning mechanism 3, a driving assembly 5 and a clamping device 6 are arranged on the machine tool 1. The cutting assembly 2 includes a moving plate 21, a mounting plate 22 and a cutting blade 241. The moving plate 21 is located below the cutting groove 11. Guide posts 211 are arranged on the upper side of the mounting plate 22, and the mounting plate 22 is mounted on the guide posts 211. A motor 24 is arranged on the mounting plate 22, and the cutting blade 241 is connected to the motor 24, and the upper side of the cutting blade 241 extends out of the cutting groove 11. The mounting plate 22 can drive the motor 24 to move vertically on the guide posts 211 for adjusting the cutting depth of the cutting blade 241. The cleaning mechanism 3 includes a collection tank 31 and a sweeping assembly 4. The upper end of the collection tank 31 is mounted on the bottom side of the cutting groove 11 to enclose the cutting blade 241, and the side of the collection tank 31 is connected to the mounting plate 22. The sweeping assembly 4 includes a sliding box 41 and a disc brush 49. The outer side of the sliding box 41 is connected to the inner side of the collection tank 31, and the disc brush 49 is mounted at the bottom of the sliding box 41. The driving assembly 5 is cooperated below the moving plate 21 for driving the moving plate 21 to move on the machine tool 1, driving the cutting blade 241 on the mounting plate 22 to perform cutting processing on the workpiece. When the mounting plate 22 moves, it drives the collection tank 31 to move synchronously, thereby driving the sliding box 41 to move in the cutting groove 11, driving the disc brush 49 to rotate to sweep the chips in the cutting groove 11 into the collection tank 31. The clamping device 6 is mounted above the cutting groove 11 for clamping the workpiece.

[0030] Among them, during use, first place the workpiece to be processed on the bed surface of the machine tool 1, so that the part of the workpiece to be cut covers the cutting groove 11, aligns with the cutting blade 241, and clamps and fixes the workpiece through the clamping device 6. Subsequently, start cutting the workpiece. At this time, both the moving plate 21 and the mounting plate 22 are in their initial positions. The moving plate 21 is located at one end of the machine tool 1, and the mounting plate 22 descends to the lowest height on the guide rod, and the cutting depth of the cutting blade 241 is the shallowest. When cutting, the motor 24 drives the cutting blade 241 to rotate, and the driving assembly 5 drives the moving plate 21 to drive the mounting plate 22 to move towards the other end of the machine tool 1, so that the rotating cutting blade 241 cuts the workpiece. During the cutting process, the cutting blade 241 throws the chips generated by cutting the workpiece into the cutting groove 11, causing some chips to fall into the collection groove 31 and the other part to remain in the cutting groove 11 between the two sliding boxes 41. As the sliding box 41 moves with the cutting blade 241, the rotating disk brush 49 under the sliding box 41 sweeps the chips in the cutting groove 11 into the collection groove 31. When the workpiece is completed with cutting, the motor 24 stops working, causing the cutting blade 241 to stop rotating. Open the clamping device 6, take out the processed workpiece, and then the driving assembly 5 drives the moving plate 21 to move back to the initial position for cutting the next workpiece. During the reset process of the moving plate 21, the sliding box 41 moves in the opposite direction in the cutting groove 11, and the cutting groove 11 is cleaned again through the rotating disk brush 49. When it is necessary to increase the cutting depth of the cutting blade 241, control the mounting plate 22 to approach the bed surface of the machine tool 1 on the guide rod, so that the cutting blade 241 gradually rises from the cutting groove 11. When the mounting plate 22 moves up to the maximum height and reaches the top of the guide rod, the mounting plate 22 stops moving. At this time, the cutting depth of the cutting blade 241 is the deepest.

[0031] The difference from the above embodiment is that the cutting groove 11 is opened on the bed surface of the machine tool 1. The middle part of the cutting groove 11 is open, and the upper side of the cutting blade 241 extends out from the opening of the cutting groove 11. Groove openings 111 are opened on the side walls on both sides of the cutting groove 11. Sliding grooves 12 and leakage grooves 13 are respectively opened at the bottom of the bed surface of the machine tool 1. The sliding groove 12 is located below the cutting groove 11 and corresponds to the outside of the collection groove 31. The leakage groove 13 is between the sliding groove 12 and the cutting groove 11, and the cutting groove 11 communicates with the leakage groove 13 through the groove opening 111. The leakage groove 13 is located inside the collection groove 31. A driving rack 14 is fixedly connected to the top of the leakage groove 13, and the tooth surface of the driving rack 14 is located above the groove opening 111.

[0032] Among them, during the process of the cutting blade 241 cutting the workpiece, a part of the chips thrown by the cutting blade 241 will accumulate on both sides of the bottom opening of the cutting groove 11. When this part of the chips accumulates too much, some will naturally fall into the collection groove 31, and some will enter the leakage groove 13 through the notch 111 and fall into the collection groove 31 from the leakage groove 13. The remaining chips are cleaned into the collection groove 31 by the cleaning assembly 4.

[0033] The difference from the above embodiment is that a guide post 211 is fixedly connected to each of the four corners of the moving plate 21. Fixed buckles 212 are fixedly connected to both sides of the upper end of the moving plate 21. The fixed buckles 212 are located between the two guide posts 211 on the same side. The mounting plate 22 is slidably mounted on the guide posts 211. A limiting groove 221 is formed on the side of the mounting plate 22 facing the collection groove 31. A driving cylinder 23 is arranged between the moving plate 21 and the mounting plate 22. The bottom of the driving cylinder 23 is fixedly mounted on the moving plate 21. The output shaft of the driving cylinder 23 is fixedly connected to the bottom of the mounting plate 22. The motor 24 is fixedly mounted on the mounting plate 22. The cutting blade 241 is coaxially and fixedly connected to the output shaft of the motor 24.

[0034] Among them, initially, the driving cylinder 23 fully retracts its output shaft, causing the mounting plate 22 to descend to the lowest height, making the cutting depth of the cutting blade 241 the shallowest. When it is necessary to increase the cutting depth, the driving cylinder 23 extends its output shaft to push the mounting plate 22 to move upward, thereby increasing the cutting depth of the cutting blade 241. When the driving cylinder 23 fully extends its output shaft, the mounting plate 22 rises to the maximum height and stops rising, making the cutting depth of the cutting blade 241 the deepest, so that the device can process the workpiece with different cutting depths, increasing the applicability of the device.

[0035] The difference from the above embodiment is that a limiting strip 311 is fixedly connected to the side of the collection groove 31 facing the mounting plate 22. The limiting strip 311 is slidably mounted in the limiting groove 221. A sliding block 32 is fixedly connected to the outer side of the upper end of the collection groove 31. The sliding block 32 is slidably mounted in the sliding groove 12. A lifting groove 33 is formed in the collection groove 31. The output shaft of the motor 24 passes through the lifting groove 33, so that the cutting blade 241 is located in the collection groove 31. The lower end of the collection groove 31 is communicated with the waste box 35 through a hose 34. The waste box 35 is fixedly mounted on the bottom of the machine tool 1.

[0036] Among them, when the mounting plate 22 is at the lowest height, the limiting groove 221 on the mounting plate 22 is located at the lowermost end of the limiting strip 311. When the mounting plate 22 rises, it will drive the limiting groove 221 to slide upward along the limiting strip 311. When the moving plate 21 drives the mounting plate 22 to move towards the other end of the machine tool 1, the mounting plate 22, through the cooperation of the limiting groove 221 and the limiting strip 311, pushes the collection tank 31 to move synchronously under the cutting groove 11. During the cutting process, the chips falling into the collection tank 31 will fall into the waste bin 35 through the hose 34 for centralized collection.

[0037] The difference from the above embodiment is that a sliding box 41 is provided at each end of the collection tank 31. The width of the sliding box 41 matches the width of the cutting groove 11. The sliding box 41 is in an H shape, and the grooves at both ends of its H shape correspond to the openings of the cutting groove 11. Connecting pieces 411 are fixedly installed on the outer sides of both ends of the sliding box 41. The connecting pieces 411 extend out from the groove opening 111 and penetrate into the collection tank 31, and are fixedly connected to the inner side of the collection tank 31. A driving rod 42 is rotatably installed in the middle of the sliding box 41. Both ends of the driving rod 42 penetrate through the groove opening 111 and extend into the leakage groove 13. A driving gear 421 is coaxially and fixedly connected to the end of the driving rod 42 located in the leakage groove 13. The driving gear 421 meshes with the driving rack 14. Both ends of the driving rod 42 located in the sliding box 41 are fixedly connected with worm gears 422, and the thread directions of the two worm gears 422 are opposite.

[0038] Among them, there is a gap between the sliding box 41 provided at both ends of the collection tank 31 and the end of the collection tank 31, so that the disk brush 49 at one end of the sliding box 41 close to the end of the collection tank 31 can also sweep the residual chips in the cutting groove 11 into the collection tank 31. During the process of cutting the workpiece, the collection tank 31 drives the sliding box 41 to move in the cutting groove 11 through the connecting piece 411. When cutting, the sliding box 41 follows the collection tank 31 to move from the initial position towards the other end of the machine tool 1, so that the driving gear 421 drives the driving rod 42 to rotate in the reverse direction under the cooperation of the driving rack 14. After the cutting is completed, the sliding box 41 follows the collection tank 31 to move in the reverse direction and return to the initial position, so that the driving gear 421 drives the driving rod 42 to rotate in the forward direction under the cooperation of the driving rack 14.

[0039] The difference from the above embodiment is that mounting seats 43 are fixedly installed on both sides inside the sliding box 41. A transmission rod 44 is rotatably installed on the mounting seats 43. A worm gear 45 is coaxially and fixedly connected to the middle of the transmission rod 44. The worm gear 45 meshes with the worm gear 422. Driving bevel gears 46 are coaxially and fixedly connected to both ends of the transmission rod 44. Four rotating shafts 47 are respectively rotatably installed at the bottoms of both ends of the sliding box 41. The upper ends of the rotating shafts 47 are located inside the sliding box 41, and transmission bevel gears 48 are coaxially and fixedly connected thereto. The transmission bevel gears 48 mesh with the driving bevel gears 46. The lower ends of the rotating shafts 47 are located outside the sliding box 41 and are coaxially and fixedly connected to the disk brush 49.

[0040] Among them, when the driving rod 42 rotates in the reverse direction, the worms 422 with opposite thread directions at both ends of the driving rod 42 will respectively drive the transmission rods 44 on both sides of the sliding box 41 to rotate towards each other. The transmission rods 44 drive the rotating shafts 47 at both ends of the sliding box 41 to rotate towards each other through the driving bevel gears 46 at both ends. When the driving rod 42 rotates in the forward direction, the worms 422 with opposite thread directions at both ends of the driving rod 42 will respectively drive the transmission rods 44 on both sides of the sliding box 41 to rotate in the reverse direction. The transmission rods 44 drive the rotating shafts 47 at both ends of the sliding box 41 to rotate in the reverse direction through the driving bevel gears 46 at both ends, so that the two disc brushes 49 at the moving direction end of the sliding box 41 can rotate towards the opening direction of the cutting groove 11, and sweep the chips in the cutting groove 11 into the collection groove 31.

[0041] The difference from the above embodiment is that push shovels 412 are fixedly connected to both ends of the sliding box 41. The shoveling heads of the push shovels 412 are in contact with the inner wall of the cutting groove 11, and the shoveling surfaces of the push shovels 412 are inclined towards the inside of the cutting groove 11.

[0042] Among them, when the sliding box 41 moves, the sliding box 41 will push the push shovel 412 in its moving direction to shovel the chips in the cutting groove 11. The shoveled chips will gather towards the middle of the cutting groove 11 along the inclined shoveling surface of the push shovel 412, and thus fall into the collection groove 31.

[0043] The difference from the above embodiment is that the driving assembly 5 includes a guide rail 51, a driving shaft 52, and a driving motor 55. The guide rail 51 is fixedly installed at the bottom of the machine tool 1. The moving plate 21 is slidably installed on the guide rail 51 through a slider. Two driving shafts 52 are rotatably installed at the bottom of the machine tool 1. The two driving shafts 52 are respectively located at both ends of the guide rail 51. A transmission gear 53 is coaxially and fixedly connected to the driving shaft 52. The two driving shafts 52 are connected by a toothed belt 54. The toothed belt 54 is engaged with the transmission gear 53, and the toothed belt 54 located on the upper side is fixedly connected to the fixing buckle 212. The driving motor 55 is fixedly installed on the machine tool 1, below one end of the guide rail 51 away from the waste box 35. A pulley 56 is fixedly connected to the driving shaft 52 close to the driving motor 55. A transmission belt 57 is connected between the output shaft of the driving motor 55 and the pulley 56.

[0044] Among them, when starting cutting, the driving motor 55 drives the driving shaft 52 to rotate forward through the transmission belt 57, thereby driving the toothed belt 54, so that the toothed belt 54 pulls the moving plate 21 to move on the guide rail 51 from the initial position towards the driving motor 55 direction. After the cutting is completed, the driving motor 55 drives the driving shaft 52 to rotate in the reverse direction through the transmission belt 57, so that the toothed belt 54 pulls the moving plate 21 to move in the reverse direction and return to the initial position.

[0045] Embodiment Two;

[0046] The difference from the above embodiment is that the clamping device 6 is fixedly installed on the upper side of the bed surface of the machine tool 1 and is located on the side of the cutting groove 11.

[0047] Among them, when machining a workpiece, the workpiece is placed on the bed surface of the machine tool 1, and the clamping device 6 clamps the workpiece under the drive of the cylinder, so that the position of the workpiece to be cut is aligned with the cutting blade 241. After the cutting is completed, the clamping device 6 releases the workpiece under the drive of the cylinder again.

[0048] The present invention also provides a cutting method for machining automotive parts, which uses a cutting device.

[0049] Working principle: When in use, first place the workpiece to be machined on the bed surface of the machine tool 1, so that the part of the workpiece to be cut covers the cutting groove 11 and is aligned with the cutting blade 241, and clamp and fix the workpiece through the clamping device 6. Subsequently, start machining the workpiece. At this time, the moving plate 21 and the mounting plate 22 are both in the initial position. The moving plate 21 is located at one end of the machine tool 1, and the mounting plate 22 descends to the lowest height on the guide rod, and the cutting depth of the cutting blade 241 is the shallowest. When cutting, the motor 24 drives the cutting blade 241 to rotate, and the drive motor 55 drives the drive shaft 52 to rotate forward through the transmission belt 57, thereby driving the toothed belt 54, so that the toothed belt 54 pulls the moving plate 21 to move on the guide rail 51 from the initial position towards the drive motor 55 direction. The rotating cutting blade 241 cuts the workpiece. At the same time, the mounting plate 22 drives the collection groove 31 and the sliding box 41 to move synchronously. During the cutting process, the cutting blade 241 throws the chips generated by cutting the workpiece into the cutting groove 11, causing a part of the chips to fall into the collection groove 31, and the other part remains in the cutting groove 11 between the two sliding boxes 41. As the sliding box 41 moves towards the drive motor 55 following the cutting blade 241, the drive rod 42 drives the disc brush 49 to rotate through the transmission rod 44 to sweep the chips in the cutting groove 11 into the collection groove 31. Among them, when the sliding box 41 moves, the sliding box 41 will push the pusher 412 in its moving direction to shovel the chips in the cutting groove 11, and the shoveled chips will gather towards the middle of the cutting groove 11 along the inclined shovel surface of the pusher 412, and thus fall into the collection groove 31;

[0050] After the workpiece is completed with cutting, the motor 24 stops working, causing the cutting blade 241 to stop rotating. The clamping device 6 is opened, and the processed workpiece is taken out. Subsequently, the driving assembly 5 drives the moving plate 21 to move back to the initial position for cutting the next workpiece. During the reset process of the moving plate 21, the sliding box 41 moves in the reverse direction in the cutting groove 11, and the cutting groove 11 is cleaned again by the rotating disk brush 49. When it is necessary to increase the cutting depth, the driving cylinder 23 extends its output shaft to push the mounting plate 22 to move upward, thereby increasing the cutting depth of the cutting blade 241. When the driving cylinder 23 fully extends its output shaft, the mounting plate 22 rises to the maximum height and stops rising, making the cutting depth of the cutting blade 241 the deepest. Thus, the device can process workpieces with different cutting depths, increasing the applicability of the device.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
