Description

Technical Field

[0001] The invention relates to the technical field of hand plate processing, in particular to a processing method for CNC hand plate engraving. Background Art

[0002] CNC prototype engraving is a process that uses computer numerical control technology to accurately engrave prototypes. It combines computer technology, precision manufacturing technology, and automation technology to complete the precise processing of complex shapes and structures. Because its processing method has the characteristics of high efficiency, high precision, and high stability, it has a wide range of applications in design verification, product development, and prototype production.

[0003] In the prior art, when CNC handboard engraving processing needs to process a larger handboard, the larger handboard will cause the processing method to be too time-consuming when adjusting the engraving position, thereby reducing the processing efficiency of the CNC handboard engraving processing. In addition, a large adjustment of the engraving position will also increase energy consumption and increase the cost of CNC handboard engraving processing. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that when CNC handboard engraving processing needs to process a handboard with a larger size, the larger handboard will cause the processing method to be too time-consuming when adjusting the engraving position, thereby reducing the processing efficiency of the CNC handboard engraving processing, and a large adjustment of the engraving position will also increase energy consumption and increase the cost of CNC handboard engraving processing, and a processing method for CNC handboard engraving is proposed.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A processing method for CNC handboard engraving, the method comprising the following steps:

[0007] Step 1: Place the hand plate on the placement plate, and then rotate the double-threaded rod. Since the double-threaded rod is threadedly connected with a pair of clamping plates, the rotation of the double-threaded rod drives the pair of clamping plates to move toward the center or both sides at the same time, so that the pair of clamping plates clamp the hand plate;

[0008] Step 2: When the material of the prototype to be processed is a soft material, a pair of clamping plates are fitted with the edge of the prototype of the soft material by rotating the double-threaded rod, and then the slider is moved to slide in the slide groove, so that the slider drives the lower pressing plate to move. When the lower pressing plate moves to the corner of the prototype of the soft material, the lower pressing plate is aligned with the corner of the prototype of the soft material, so that the lower pressing plate is pressed on the corner of the prototype of the soft material. At this time, the four corners of the prototype of the soft material are squeezed and fixed by the two pairs of lower pressing plates;

[0009] Step 3: After the hand plate is fixed, the motor drives the threaded shaft to rotate, so that the rotation of the threaded shaft drives the sliding plate to move. The movement of the sliding plate drives the vertical plate and the first rack to move through the second square plate. Since the first rack and the first gear are meshed with each other, the movement of the first rack drives the first gear to rotate. Since the first gear and the gear groove on the placement plate are meshed with each other, the rotation of the first gear drives the placement plate to move. At this time, the movement directions of the sliding plate and the placement plate are opposite.

[0010] Step 4: After the engraving device has adjusted its position by moving the sliding plate, the hydraulic cylinder drives the square block to move downward, so that the square block drives the engraving device to move downward, and the engraving device performs engraving processing on the hand plate;

[0011] Step 5: After the engraving device has engraved the hand plate, the hydraulic cylinder drives the square block and the engraving device to move upward. When the square block moves upward, the upward movement of the square block drives the second rack to move upward through the first connecting block. Since the second gear and the second rack are meshed with each other, the movement of the second rack drives the second gear to rotate. The rotation of the second gear drives the first threaded rod to rotate. Since the first threaded rod is threadedly connected to the linkage plate, and the linkage plate is limited by the circular rod, the rotation of the first threaded rod drives the linkage plate to move forward and backward. The movement of the linkage plate drives the cleaning plate to move. The forward and backward movement of the cleaning plate will clean the top of the outer wall of the hand plate after engraving, so that the waste chips remaining on the hand plate after engraving are cleaned by the cleaning plate;

[0012] Step 6: The linkage plate includes a bottom plate and a movable plate, so that when the thickness of the hand plate to be processed is different, the second threaded rod is rotated. Since the second threaded rod is threadedly connected to the bottom plate, the rotation of the second threaded rod causes the second threaded rod to move up and down, so that the second threaded rod drives the movable plate to move up and down, and the movable plate drives the cleaning plate to move up and down, so that the cleaning plate can adjust the height according to the thickness of the hand plate required for processing;

[0013] Step 7: The cleaning plate includes a square shell and a square plate, so that when the height of the cleaning plate is adjusted according to the thickness of the hand plate, the outer wall of the square plate is slidably connected to the inner wall of the square shell; the top end of the inner wall of the square shell is fixedly connected to a first spring, and the bottom end of the outer wall of the first spring is fixedly connected to the top end of the outer wall of the square plate, so that when the square plate cleans the hand plate, it will be retractable through the first spring, and then an inclined surface is provided at the bottom end of the outer wall of the square plate, so that when the square plate moves back and forth to clean the hand plate, when the square plate encounters the hand plate, the square plate will drive the first spring to contract through the inclined surface, and when the square plate is located above the hand plate, the elastic force of the first spring will make the square plate fit the hand plate;

[0014] Step eight: when the square plate cleans the hand plate, the movement of the square plate drives the second rotating rod and the cleaning brush plate to move. When the second rotating rod and the cleaning brush plate move back and forth, the outer wall of the second rotating rod is fixedly connected with the eighth gear; one side of the outer wall of the vertical plate is slidably connected with the eighth rack, and the eighth rack and the eighth gear are meshed with each other, so that the rotation of the second rotating rod drives the eighth gear to move on the eighth rack, so that the eighth gear rotates when moving, and the rotation of the eighth gear drives the second rotating rod and the cleaning brush plate to rotate, so that the rotating cleaning brush plate cleans the hand plate;

[0015] Step nine: when the cleaning plate moves back and forth to clean the opponent plate, the back and forth movement of the cleaning plate will drive the rotating rod and the grinding block to move through the third plate, and the back and forth movement of the cleaning plate will also drive the first rotating rod and the fifth gear to move through the second connecting block. Because the top end of the outer wall of the square rod is fixedly connected with a fifth rack, the fifth rack and the fifth gear are meshed with each other, so that when the fifth gear moves back and forth, the fifth rack remains stationary and the fifth gear remains moving, so that when the first gear moves on the fifth rack, the fifth gear will rotate while moving, so that the rotation of the fifth gear drives the first rotating rod to rotate, and the first rotating rod drives the fourth bevel gear to rotate. Because the fourth bevel gear and the third bevel gear are meshed with each other, the rotation of the fourth bevel gear drives the rotating rod to rotate through the third bevel gear, so that the rotating rod drives the grinding block to rotate, so that the grinding block grinds and removes burrs on the engraved area of ​​the opponent plate;

[0016] Step 10: When the prototype is completed with the engraving, cleaning and polishing processes, the pair of clamping rods are released by reversing the double-threaded rods. At this time, the prototype is taken out to complete the engraving process of the prototype.

[0040] Embodiment 1:

[0041] See also Figure 1 - Figure 8 As shown, a processing method for CNC handboard engraving is realized by a processing device for CNC handboard engraving, the device comprising a workbench 1; a support column 2 is fixedly connected to the top corner of the outer wall of the workbench 1; a motor 3 is fixedly connected to one side of the outer wall of the support column 2 through a fixing block; a threaded shaft 4 is provided at the output end of the motor 3, and one end of the outer wall of the threaded shaft 4 penetrates the support column 2; a sliding plate 5 is threadedly connected to the outer wall of the threaded shaft 4; a guide rod 6 is fixedly connected to one side of the outer wall of the support column 2, and one end of the outer wall of the guide rod 6 penetrates the sliding plate 5, and the guide rod 6 is slidably connected to the sliding plate 5; one side of the outer wall of the sliding plate 5 is fixed by a first square plate A hydraulic cylinder 7 is connected; a square block 8 is fixedly connected to the conveying end of the hydraulic cylinder 7; an engraving device 9 is fixedly connected to the bottom end of the outer wall of the square block 8; a placement plate 10 is slidably connected to the top end of the outer wall of the workbench 1; a fixing piece is provided at the top end of the outer wall of the placement plate 10; the fixing piece includes a double-threaded rod 11; a group of gear grooves 12 are opened on one side of the outer wall of the placement plate 10; a first gear 13 is rotatably connected to the top end of the outer wall of the workbench 1 through a first round rod, and the first gear 13 and the gear groove 12 are meshed with each other; a vertical plate 14 is fixedly connected to one side of the outer wall of the sliding plate 5 through a second square plate; a first rack 15 is fixedly connected to the bottom end of the outer wall of the vertical plate 14, and the first rack 15 is meshed with the gear groove 12. The first gears 13 mesh with each other, and the motor 3 drives the threaded shaft 4 to rotate. Since the threaded shaft 4 is threadedly connected with the sliding plate 5, the rotation of the threaded shaft 4 drives the sliding plate 5 to move. Since the sliding plate 5 is limited by the guide rod 6 and cannot rotate, the movement of the sliding plate 5 drives the hydraulic cylinder 7, the square block 8 and the engraving device 9 to move, so that the engraving device 9 can move. When the engraving device 9 is needed to engrave, the hydraulic cylinder 7 drives the square block 8 to move downward, so that the square block 8 drives the engraving device 9 to move downward to complete the engraving. When the engraving device 9 moves its position through the motor 3, the movement of the sliding plate 5 drives the vertical plate 14 and the second square plate to move downward. The first rack 15 moves, and because the first rack 15 and the first gear 13 are meshed with each other, the movement of the first rack 15 drives the first gear 13 to rotate. Because the first gear 13 and the gear groove 12 on the placement plate 10 are meshed with each other, the rotation of the first gear 13 drives the placement plate 10 to move, so that the hand plate can be placed on the placement plate 10 when it needs to be engraved, and when the engraving device 9 moves, the placement plate 10 moves in the opposite direction at the same time, thereby reducing the moving distance of the engraving device 9, thereby improving the processing efficiency of the device for CNC hand plate engraving, and reducing the operation time of the motor 3, thereby reducing energy consumption.

[0042] A square rod 18 is fixedly connected to one side of the outer wall of the vertical plate 14; a first threaded rod 19 is rotatably connected to one side of the outer wall of the square rod 18; a linkage plate 20 is threadedly connected to the outer wall of the first threaded rod 19; a round rod 21 is fixedly connected to one side of the outer wall of the square rod 18, and one end of the outer wall of the round rod 21 passes through the linkage plate 20, and the round rod 21 is slidably connected to the linkage plate 20; a cleaning plate 22 is fixedly connected to one side of the outer wall of the linkage plate 20, and the cleaning plate 22 is located below the engraving device 9; one side of the outer wall of the square block 8 is connected to the first threaded rod 19; A second rack 23 is fixedly connected to a connecting block, and the second rack 23 is L-shaped; a second gear 24 is fixedly connected to the outer wall of the first threaded rod 19, and the second gear 24 and the second rack 23 are meshed with each other. When the engraving device 9 engraves the hand plate, the hydraulic cylinder 7 drives the square block 8 and the engraving device 9 to move up. When the square block 8 moves up, the upward movement of the square block 8 will drive the second rack 23 to move up through the first connecting block. Because the second gear 24 and the second rack 23 are meshed with each other, the movement of the second rack 23 The second gear 24 is driven to rotate. Since the second gear 24 is fixedly connected to the first threaded rod 19, the rotation of the second gear 24 drives the first threaded rod 19 to rotate. Since the first threaded rod 19 is threadedly connected to the linkage plate 20, and the linkage plate 20 is limited by the circular rod 21, the rotation of the first threaded rod 19 drives the linkage plate 20 to move forward and backward. The forward and backward movement of the linkage plate 20 drives the cleaning plate 22 to move forward and backward. Since the cleaning plate 22 is located below the engraving device 9, the forward and backward movement of the cleaning plate 22 will clean the top of the outer wall of the hand plate after the engraving is completed, so that the waste chips remaining on the hand plate after the engraving is cleaned by the cleaning plate 22, so that when the engraving device 9 needs to continue engraving, the remaining waste chips will not affect the processing of the engraving device 9, and the waste chips can be cleaned, so that the staff can observe the processing of the hand plate, so as to facilitate the staff to adjust the equipment, so that when the device processes the hand plate, it can not only reduce the influence of the waste chips on the processing of the hand plate, but also enable the device to process the hand plate more accurately.

[0043] A square groove 16 is provided at the top of the outer wall of the placement plate 10; a pair of clamping plates 17 are slidably connected to the inner side wall of the square groove 16, and the pair of clamping plates 17 are T-shaped; the pair of clamping plates 17 are symmetrical about the center line of the placement plate 10; one end of the outer wall of the double-threaded rod 11 is rotatably connected to one side of the inner wall of the square groove 16, and the other end of the outer wall of the double-threaded rod 11 passes through a pair of clamping plates 17 and the placement plate 10; the double-threaded rod 11 is threadedly connected to the pair of clamping plates 17, and by rotating the double-threaded rod 11, because the double-threaded rod 11 is threadedly connected to the pair of clamping plates 17, the rotation of the double-threaded rod 11 drives the pair of clamping plates 17 to move toward the center or both sides at the same time, so that when the hand plate needs to be engraved, the hand plate is placed on the placement plate 10, and then by rotating the double-threaded rod 11, the pair of clamping plates 17 can clamp and fix the hand plate, so that the hand plate is more stable when engraving, and it is not easy to have defects when engraving.

When the cleaning plate 22 moves forward and backward to clean the opponent plate, the forward and backward movement of the cleaning plate 22 will drive the rotating rod 26 and the grinding block 27 to move through the third plate, and the forward and backward movement of the cleaning plate 22 will also drive the first rotating rod 29 and the fifth gear 31 to move through the second connecting block. Because the top of the outer wall of the square rod 18 is fixedly connected with the fifth rack 32, and the fifth rack 32 is in the shape of L; the fifth rack 32 is meshed with the fifth gear 31. When the fifth gear 31 moves forward and backward, the fifth rack 32 remains stationary while the fifth gear 31 remains in a moving state. When the first gear 13 moves on the fifth rack 32, the fifth gear 31 rotates while moving, so that the rotation of the fifth gear 31 drives the first rotating rod 29 to rotate, and the first rotating rod 29 drives the fourth bevel gear 30 to rotate. Since the fourth bevel gear 30 and the third bevel gear 28 are meshed with each other, the rotation of the fourth bevel gear 30 drives the rotating rod 26 to rotate through the third bevel gear 28, so that the rotating rod 26 drives the rotating rod 26 to rotate. The movable grinding block 27 rotates to make the cleaning plate 22 clean the hand plate. The grinding block 27 will move while grinding and removing burrs on the hand plate area after processing, so that the device can not only perform engraving processing on the hand plate, but also clean and grind the hand plate at the same time. The engraving, cleaning and grinding cooperate with each other and will not affect the operation of each other, making the device more convenient. The grinding process can be reduced after the hand plate is processed, thereby reducing the time required for hand plate engraving processing and further improving the efficiency of hand plate processing.

[0045] The cleaning plate 22 includes a square shell 221 and a square plate 222; the outer side wall of the square plate 222 is slidably connected to the inner side wall of the square shell 221; the top end of the inner wall of the square shell 221 is fixedly connected to a first spring, and the bottom end of the outer wall of the first spring is fixedly connected to the top end of the outer wall of the square plate 222; the bottom end of the outer wall of the square plate 222 is provided with an inclined surface 33, and the inclined surface 33 matches the placement plate 10. The cleaning plate 22 includes a square shell 221 and a square plate 222, so that when the height of the cleaning plate 22 is adjusted according to the thickness of the hand plate, the outer side wall of the square plate 222 is slidably connected to the inner side wall of the square shell 221; the top end of the inner wall of the square shell 221 is fixedly connected to a first spring, and the bottom end of the outer wall of the first spring is fixedly connected to the top end of the outer wall of the square plate 222, so that the square plate 222 is adjusted to the height of the cleaning plate 22 according to the thickness of the hand plate. When the hand plate is cleaning, the first spring will be retractable, and the outer wall bottom end of the square plate 222 is provided with an inclined surface 33, so that when the square plate 222 moves back and forth to clean the hand plate, when the square plate 222 encounters the hand plate, the inclined surface 33 of the square plate 222 will encounter the hand plate. At this time, the square plate 222 will drive the first spring to contract through the inclined surface 33.

In the moving state, when the first gear (13) moves on the fifth rack (32), the fifth gear (31) rotates while moving, so that the rotation of the fifth gear (31) drives the first rotating rod (29) to rotate, and the first rotating rod (29) drives the fourth bevel gear (30) to rotate. Since the fourth bevel gear (30) and the third bevel gear (28) are meshed with each other, the rotation of the fourth bevel gear (30) drives the rotating rod (26) to rotate through the third bevel gear (28), so that the rotating rod (26) drives the grinding block (27) to rotate, so that the grinding block (27) grinds and removes burrs on the engraved area of ​​the hand plate; Step 10: After the handboard has completed the engraving, cleaning and polishing processes, the pair of clamping rods are released by reversing the double-threaded rods (11), and the handboard is taken out at this time, completing the engraving process of the handboard.
