Description

Technical Field

[0001] This application relates to the technical field of drilling machinery, and in particular to an automatic drilling machine with a correction device. Background Technology

[0002] Drilling machines are a collective term for machines and equipment that use tools that are harder and sharper than the target object to leave cylindrical holes or openings in the target object through rotary cutting or rotary extrusion.

[0003] In related technologies, one can refer to Chinese utility model patent with authorization announcement number CN205673627U, which discloses a drilling machine, including a frame, a clamp slidably connected to the frame, and a drilling part disposed on the frame and located on one side of the clamp. The feature is that a limiting member is slidably disposed on the frame, and the limiting member can slide against the clamp to restrict the clamp from moving toward the drilling part. The limiting member is provided with a fixing part that can fix the limiting member.

[0004] However, when drilling forgings, the aforementioned drilling machine requires manual placement of the forgings at the designated drilling position, which is highly dependent on manual labor. When drilling a large number of forgings, the workload is heavy and the efficiency is low. Summary of the Invention

[0005] To reduce the workload of placing forgings during drilling, this application provides an automatic drilling machine with a correction device.

[0006] This application provides an automatic drilling machine with a correction device, which adopts the following technical solution: An automatic drilling machine with a calibration device includes a frame and a drilling head mounted on the frame. The frame has a worktable for placing forgings. The drilling head is located on one side of the worktable and performs drilling operations on the forgings on the worktable. The frame also has a feeding mechanism for feeding the forgings onto the worktable. The feeding mechanism includes: A conveyor belt, which is rotatably mounted on a frame, with one end of the conveyor belt connected to a worktable; A first drive assembly is mounted on a frame and is used to drive the conveyor belt to rotate. A feeding block, which slides and rotates along the conveyor belt toward the worktable and is mounted on the frame; Two clamping arms, both of which are rotatably mounted on the feeding block; The second drive assembly is mounted on the frame and is used to drive the feed block to move horizontally. A third drive assembly is mounted on the frame and is used to drive the feed block to rotate. A fourth drive assembly is mounted on the frame and is used to drive two clamping arms to rotate, the two clamping arms clamping the forging under the action of the fourth drive assembly.

[0007] By adopting the above technical solution, the worker places the forging onto the conveyor belt. The first drive component starts and drives the conveyor belt to rotate, which in turn moves the forging. The conveyor belt delivers the forging to the worktable. Then, the fourth drive component starts and drives the two clamping arms to rotate, which clamp the forging. After the two clamping arms hold the forging, the second drive component starts and drives the feeding block to move horizontally, which moves the forging to the drilling position of the drilling machine head. At the same time, the third drive component starts and drives the feeding block to rotate, which aligns the drilling position of the forging with the drilling machine head. This completes the feeding of the forging and the adjustment and alignment of the forging's position during drilling. This allows the worker to simply place the forging onto the conveyor belt, greatly reducing workload and making the position of the forging more accurate during drilling, thus improving work efficiency and drilling quality.

[0008] Optionally, the first driving component includes: Two first drive wheels are rotatably mounted on the frame, and the conveyor belt is sleeved on the two first drive wheels; A first drive motor is mounted on the frame and its output shaft is connected to one of the two first drive wheels.

[0009] By adopting the above technical solution, the first drive motor starts and drives one of the two first drive wheels to rotate. The rotation of the first drive wheel drives the conveyor belt to rotate, and the rotation of the conveyor belt drives the forging to move. Thus, the conveying of the forging is realized by controlling the first drive motor.

[0010] Optionally, two first guide plates are provided on the frame above the conveyor belt. The gap between the two first guide plates is only wide enough for one forging to pass through. Two second guide plates are provided at the ends of the two first guide plates away from the worktable. The distance between the ends of the two second guide plates near the worktable is smaller than the distance between the ends away from the worktable.

[0011] By adopting the above technical solution, two first guide plates are installed above the conveyor belt, and two second guide plates are set at the ends of the two first guide plates away from the workbench. Multiple forgings placed on the conveyor belt enter between the two first guide plates in sequence under the guidance of the second guide plates, thereby completing the feeding of the forgings one by one.

[0012] Optionally, the second driving component includes: The second drive block is horizontally slidably mounted on the frame, and the feeding block is rotatably mounted on the second drive block; The second drive screw is rotatably mounted on the frame and threadedly connected to the second drive block. The second drive motor is mounted on the frame and its output shaft is connected to the second drive screw.

[0013] By adopting the above technical solution, the second drive motor starts and drives the second drive screw to rotate. The rotation of the second drive screw drives the second drive block to move horizontally. The movement of the second drive block drives the feeding block to move. Thus, the movement of the feeding block is realized by controlling the second drive motor.

[0014] Optionally, the third driving component includes: The third drive plate is disposed on the side wall of the feeding block; The third driving cylinder is rotatably mounted on the second driving block, and the piston rod of the third driving cylinder is rotatably connected to the third driving plate.

[0015] By adopting the above technical solution, a third drive plate is rotatably installed on the side wall of the feeding block, and a third drive cylinder is rotatably installed on the second drive block. The piston rod of the third drive cylinder is rotatably connected to the third drive plate. Thus, the rotation of the feeding block can be achieved by controlling the movement of the piston rod of the third drive cylinder. Furthermore, the rotation angle of the feeding block can be adjusted and controlled by controlling the third drive cylinder, which is convenient for the forging to be aligned with the drilling machine head when drilling is required.

[0016] Optionally, the fourth driving component includes: The fourth drive cylinder is mounted on the feeding block; Two fourth drive rods, one end of each of the two fourth drive rods is rotatably mounted on the piston rod end of the fourth drive cylinder, and the other end of each of the two fourth drive rods is rotatably connected to two clamping arms respectively.

[0017] By adopting the above technical solution, the fourth drive cylinder is started, causing the piston rod of the fourth drive cylinder to move. The movement of the piston rod of the drive cylinder drives the two fourth drive rods to move, and the movement of the two fourth drive rods drives the two clamping arms to rotate. Thus, the rotation and opening / closing of the two clamping arms is realized by controlling the fourth drive cylinder.

[0018] Optionally, a vertically sliding pusher platform is provided on the frame, and a pusher cylinder is provided on the frame. The pusher cylinder is located below the pusher platform and its piston rod is connected to the pusher platform. The pusher platform is in communication with the surface of the conveyor belt. A stop plate is provided on the pusher platform. The forging moves onto the pusher platform under the action of the conveyor belt and contacts the stop plate. A first pressure sensor is provided on the stop plate. A first controller is provided on the frame. The first controller is electrically connected to both the first pressure sensor and the pusher cylinder. When the forging contacts the first pressure sensor, the first controller controls the pusher cylinder to start and drive the pusher platform to move upward.

[0019] By adopting the above technical solution, after the conveyor belt sends the forging onto the pusher platform, the forging comes into contact with the backing plate under the action of inertia. The first pressure sensor on the backing plate transmits a pressure signal to the first controller after receiving the pressure of the forging. The first controller controls the pusher cylinder to start, and the pusher cylinder pushes the unloading platform to move. The pusher platform pushes the forging between the two clamping arms of the feeding block, thus completing the automatic feeding of the forging between the two clamping arms.

[0020] Optionally, a discharge box is provided on the frame located between the pusher and the worktable. The discharge box has an open top and casters are installed at the bottom.

[0021] By adopting the above technical solution, a discharge box with an open top is installed between the pusher table and the worktable. The drilled forgings can be placed into the discharge box for centralized collection. After the discharge box is full, it can be moved away by casters, thus completing the discharge and collection of the drilled forgings. The transportation is convenient and labor-saving.

[0022] Optionally, a toggle switch is provided on the feeding block. The toggle switch is electrically connected to the fourth drive cylinder. The toggle switch is used to control the movement of the piston rod of the fourth drive cylinder. The toggle switch has two rotation directions: a first direction and a second direction. When the toggle switch is rotated in the first direction, the piston rod of the fourth drive cylinder extends. When the toggle switch is rotated in the second direction, the piston rod of the fourth drive cylinder retracts. A second pressure sensor is provided on the end of the piston rod of the fourth drive cylinder. A second controller is provided on the feeding block. The second controller is electrically connected to both the second pressure sensor and the toggle switch. When the pusher pushes the forging to contact the second pressure sensor on the piston rod of the fourth drive cylinder, the second controller drives the toggle switch to rotate in the second direction.

[0023] By adopting the above technical solution, a toggle switch is installed on the feeding block. When the forging moves between the two clamping arms under the action of the pusher and comes into contact with the piston rod of the fourth drive cylinder, the second pressure sensor receives the pressure of the forging and sends a pressure signal to the second controller. The second controller controls the fourth drive cylinder to start and retract the piston rod. The retraction of the piston rod of the fourth drive cylinder drives the two clamping arms to clamp the forging while simultaneously rotating the toggle switch box in the second direction, thereby completing the clamping work of the two clamping arms on the forging. When the forging is drilled and the feeding block is to be moved back to its original position, the two clamping arms pass over the discharge box. At this time, the toggle switch is activated, causing it to rotate in the first direction. The fourth drive cylinder starts, and the piston rod of the fourth drive cylinder extends, causing the two clamping arms to move away from each other, thereby releasing the drilled forging. The forging then falls into the discharge box. Thus, the discharge work is completed during the resetting process of the feeding block and clamping arms, simplifying the work steps and greatly improving work efficiency.

[0024] Optionally, a one-way lever is rotatably mounted on the frame, the one-way lever being located above the discharge box. A limit plate is provided on the frame on the side of the one-way lever closer to the pusher table. A return spring is connected between the limit plate and the one-way lever. When the feeding block moves from the pusher table towards the worktable, the one-way lever is located in the first direction and is in contact with the toggle switch. Under the action of the toggle switch, the one-way lever stretches the return spring and rotates towards the worktable. When the feeding block moves from the worktable towards the pusher table, the one-way lever is in contact with the toggle switch. Under the action of the toggle switch, the one-way lever abuts against the limit plate. The one-way lever toggles the toggle switch, causing the toggle switch to rotate from the first direction to the second direction.

[0025] By adopting the above technical solution, a one-way lever is rotatably installed on the frame. When the feeding block moves from the pusher table to the worktable, the one-way lever is located in the first direction and is in contact with the toggle switch. Under the action of the toggle switch, the one-way lever stretches the return spring and rotates towards the worktable. When the feeding block moves from the worktable to the pusher table, the one-way lever is in contact with the toggle switch and abuts against the limit plate under the action of the toggle switch. The one-way lever toggles the toggle switch to rotate, causing the toggle switch to rotate from the first direction to the second direction. Thus, the automatic toggle of the one-way lever is completed when the feeding block moves, eliminating the need for manual operation, reducing workload, and improving work efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By placing the forging onto the conveyor belt, the first drive assembly starts and drives the conveyor belt to rotate. The rotation of the conveyor belt moves the forging and delivers it to the worktable. Then, the fourth drive assembly starts and drives the two clamping arms to rotate. The two clamping arms clamp the forging. After the two clamping arms hold the forging, the second drive assembly starts and drives the feeding block to move horizontally. The horizontal movement of the feeding block moves the forging to the drilling position of the drilling machine head. At the same time, the third drive assembly starts and drives the feeding block to rotate. The rotation of the feeding block aligns the drilling position of the forging with the drilling machine head. This completes the feeding of the forging and the adjustment and alignment of the forging's position during drilling. This allows the operator to simply place the forging onto the conveyor belt, greatly reducing the workload and making the position of the forging more accurate during drilling, thus improving work efficiency and drilling quality. 2. By installing two first guide plates above the conveyor belt and setting two second guide plates at the ends of the two first guide plates away from the workbench, multiple forgings placed on the conveyor belt enter between the two first guide plates in sequence under the guidance of the second guide plates, thus completing the feeding of the forgings one by one. 3. By installing an open discharge box between the pusher table and the worktable, the drilled forgings can be placed into the discharge box for centralized collection. After the discharge box is full, it can be moved away by casters, thus completing the discharge and collection of the drilled forgings. The transportation is convenient and labor-saving.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0030] This application discloses an automatic drilling machine with a correction device.

[0031] Reference Figure 1 An automatic drilling machine with a calibration device includes a frame 1 and a drilling head 11 fixedly connected to the frame 1. A worktable 12 is fixedly connected to the frame 1 below the drilling head 11, and forgings are placed on the worktable 12 for drilling. A feeding mechanism 2 is provided on the frame 1 for feeding the forgings onto the worktable 12.

[0032] Reference Figure 1 and Figure 2 The feeding mechanism 2 includes a conveyor belt 21, a first drive assembly 22, a feeding block 23, two clamping arms 24, a second drive assembly 25, a third drive assembly 26, and a fourth drive assembly 27. The conveyor belt 21 is rotatably mounted on the frame 1 via the first drive assembly 22, which drives the conveyor belt 21 to rotate. The first drive assembly 22 includes two first drive wheels 31 and a first drive motor 32. Both first drive wheels 31 are rotatably mounted on the frame 1 and are located at the same height. The conveyor belt 21 is fitted onto the two first drive wheels 31. The first drive motor 32 is fixedly connected to the frame 1, and its output shaft is connected to one of the two first drive wheels 31. When the first drive motor 32 starts, it drives one of the two first drive wheels 31 to rotate. The rotation of the first drive wheel 31 drives the conveyor belt 21 to rotate, and the rotation of the conveyor belt 21 moves the forging. Thus, by controlling the first drive motor 32, the conveying of the forging is achieved.

[0033] Reference Figure 1 and Figure 2 Two first guide plates 33 are fixedly connected to the frame 1 above the conveyor belt 21. The gap between the two first guide plates 33 is only wide enough for one forging to pass through. Two second guide plates 34 are provided at the ends of the two first guide plates 33 away from the worktable 12. The distance between the ends of the two second guide plates 34 closer to the worktable 12 is smaller than the distance between the ends farther from the worktable 12. Multiple forgings placed on the conveyor belt 21 enter the space between the two first guide plates 33 one by one under the guidance of the second guide plates 34.

[0034] Reference Figure 1 and Figure 2 The feeding block 23 slides and rotates along the conveyor belt 21 to the worktable 12 and is mounted on the frame 1. The second drive assembly 25 is mounted on the frame 1 and is used to drive the feeding block 23 to move horizontally. The second drive assembly 25 includes a second drive block 41, a second drive screw 42, and a second drive motor 43. The second drive block 41 slides horizontally along the conveyor belt 21 to the worktable 12 and is mounted on the frame 1. The feeding block 23 is rotatably mounted on the bottom end of the second drive block 41. The second drive screw 42 is rotatably mounted on the frame 1 and is in a horizontal state. The second drive screw 42 is threadedly connected to the second drive block 41. The second drive motor 43 is fixedly connected to the frame 1 and its output shaft is connected to the second drive screw 42. When the second drive motor 43 starts, it drives the second drive screw 42 to rotate. The rotation of the second drive screw 42 drives the second drive block 41 to move horizontally. The movement of the second drive block 41 drives the feeding block 23 to move, thereby realizing the movement of the feeding block 23 by controlling the second drive motor 43.

[0035] Reference Figure 1 and Figure 2 The third drive assembly 26 is mounted on the second drive block 41 and is used to drive the feeding block 23 to rotate. The third drive assembly 26 includes a third drive plate 51 and a third drive cylinder 52. The third drive plate 51 is fixedly connected to the outer wall of the feeding block 23 near the worktable 12. The third drive cylinder 52 is rotatably mounted on the outer wall of the second drive block 41. The piston rod of the third drive cylinder 52 is rotatably connected to the third drive plate 51. The rotation of the feeding block 23 can be achieved by controlling the movement of the piston rod of the third drive cylinder 52, and the rotation angle of the feeding block 23 can be adjusted and controlled by controlling the third drive cylinder 52, so that the forgings can be aligned with the drilling machine head 11 when drilling is required.

[0036] Reference Figure 1 and Figure 3Both clamping arms 24 are rotatably mounted on the feeding block 23. A fourth drive assembly 27 is mounted on the frame 1 and is used to drive the two clamping arms 24 to rotate. The fourth drive assembly 27 includes a fourth drive cylinder 61 and two fourth drive rods 62. The fourth drive cylinder 61 is fixedly connected to the feeding block 23. One end of each of the two fourth drive rods 62 is rotatably mounted on the piston rod end of the fourth drive cylinder 61, and the other end of each fourth drive rod 62 is rotatably connected to the two clamping arms 24 respectively. Thus, the opening and closing of the two clamping arms 24 can be achieved by the extension and retraction of the piston rod of the fourth drive cylinder 61.

[0037] Reference Figure 1 and Figure 2 A pusher cylinder 13 is fixedly connected to the frame 1 located below the two clamping arms 24. The piston rod of the pusher cylinder 13 is vertically upward. A pusher platform 14 is fixedly connected to the top of the pusher cylinder 13. A stop plate 15 is fixedly connected to the side wall of the pusher platform 14 away from the conveyor belt 21. The forging moves into the pusher platform 14 under the action of the conveyor belt 21 and comes into contact with the stop plate 15. A first pressure sensor 71 is fixedly connected to the stop plate 15. A first controller 72 is fixedly connected to the frame 1. The first controller 72 is electrically connected to both the first pressure sensor 71 and the pusher cylinder 13. When the forging contacts the first pressure sensor 71, the first controller 72 controls the pusher cylinder 13 to start and drive the pusher platform 14 to move upward.

[0038] Reference Figure 2 and Figure 3 The worker places the forging onto the conveyor belt 21. The first drive motor 32 starts, driving the conveyor belt 21 to rotate. The rotation of the conveyor belt 21 moves the forging, and the conveyor belt 21 delivers the forging to the pusher table 14. The pusher cylinder 13 starts, causing the pusher table 14 to rise and deliver the forging between the two clamping arms 24. Then, the fourth drive cylinder 61 starts, driving the two clamping arms 24 to rotate. The two clamping arms 24 clamp the forging. After the two clamping arms 24 clamp the forging, the second drive motor 43 starts, causing the feeding block 23 to move horizontally. The feeding block 23 moves horizontally to move the forging to the drilling position of the drilling machine head 11. At the same time, the third drive cylinder 52 starts to drive the feeding block 23 to rotate. The rotation of the feeding block 23 aligns the drilling position of the forging with the drilling machine head 11, thus completing the feeding of the forging and the adjustment and alignment of the forging's position during drilling. This allows the operator to simply place the forging on the conveyor belt 21, greatly reducing the workload and making the position of the forging more accurate during drilling, thereby improving work efficiency and drilling quality.

[0039] Reference Figure 2 and Figure 3A discharge box 16 is placed on the frame 1 located between the pusher table 14 and the worktable 12. The upper opening of the discharge box 16 is open, and the bottom of the discharge box 16 is equipped with casters 17. A toggle switch 28 is installed on the feeding block 23. The toggle switch 28 is electrically connected to the fourth drive cylinder 61. The toggle switch 28 is used to control the movement of the piston rod of the fourth drive cylinder 61. The toggle switch 28 has two rotation directions: a first direction and a second direction. When the toggle switch 28 rotates in the first direction, the piston rod of the fourth drive cylinder 61 extends. When the toggle switch 28 rotates in the second direction, the piston rod of the fourth drive cylinder 61 retracts. A second pressure sensor 73 is installed on the end of the piston rod of the fourth drive cylinder 61. A second controller 74 is installed on the feeding block 23. The second controller 74 is electrically connected to both the second pressure sensor 73 and the toggle switch 28. When the pusher table 14 pushes the forging to contact the second pressure sensor 73 on the piston rod of the fourth drive cylinder 61, the second controller 74 drives the toggle switch 28 to rotate in the second direction.

[0040] Reference Figure 2 and Figure 4 A one-way lever 75 is rotatably mounted on the frame 1 above the discharge box 16. A limit plate 76 is fixedly connected to the frame 1 on the side of the one-way lever 75 near the pusher table 14. A return spring 77 is connected between the limit plate 76 and the one-way lever 75.

[0041] Refer to 1 and Figure 4 When the feeding block 23 moves from the pusher table 14 towards the worktable 12, the toggle switch 28 is in the first direction, and the one-way lever 75 is in contact with the toggle switch 28. Under the action of the toggle switch 28, the one-way lever 75 stretches the return spring 77 and rotates towards the worktable 12. When the feeding block 23 moves from the worktable 12 towards the pusher table 14, the one-way lever 75 is in contact with the toggle switch 28. Under the action of the toggle switch 28, the one-way lever 75 abuts against the limit plate 76, and the one-way lever 75 causes the toggle switch 28 to rotate, so that the toggle switch 28 rotates from the first direction to the second direction. After the toggle switch 28 rotates to the second direction, the two clamping arms 24 release the forging, and the forging falls into the discharge box 16. The discharge work is completed during the reset process of the feeding block 23 and the clamping arms 24, simplifying the work steps and greatly improving work efficiency.

[0042] The working principle of this application embodiment is as follows: The worker places the forging onto the conveyor belt 21. The first drive motor 32 starts, driving the conveyor belt 21 to rotate. The rotation of the conveyor belt 21 moves the forging, and the conveyor belt 21 delivers the forging to the pusher table 14. The pusher cylinder 13 starts, causing the pusher table 14 to rise and deliver the forging between the two clamping arms 24. Then, the fourth drive cylinder 61 starts, driving the two clamping arms 24 to rotate. The two clamping arms 24 clamp the forging. After the two clamping arms 24 clamp the forging, the second drive motor 43 starts, causing the feeding block 23 to move horizontally. The feeding block 23 moves horizontally to move the forging to the drilling position of the drilling machine head 11. At the same time, the third drive cylinder 52 starts to drive the feeding block 23 to rotate. The rotation of the feeding block 23 aligns the drilling position of the forging with the drilling machine head 11, thus completing the feeding of the forging and the adjustment and alignment of the forging's position during drilling. This allows the operator to simply place the forging on the conveyor belt 21, greatly reducing the workload and making the position of the forging more accurate during drilling, thereby improving work efficiency and drilling quality.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.

The second controller (74) is electrically connected to the second pressure sensor (73) and the toggle switch (28). When the pusher (14) pushes the forging to contact the second pressure sensor (73) on the piston rod of the fourth drive cylinder (61), the second controller (74) drives the toggle switch (28) to rotate in the second direction. A one-way lever (75) is rotatably mounted on the frame (1). The one-way lever (75) is located above the discharge box (16). A limit plate (76) is provided on the side of the frame (1) where the one-way lever (75) is close to the pusher table (14). A return spring (77) is connected between the limit plate (76) and the one-way lever (75). When the feeding block (23) moves from the pusher table (14) to the worktable (12), the one-way lever (75) is located in the first direction. (75) Under the action of the feeding block (23), the return spring (77) is stretched and rotated toward the worktable (12). When the feeding block (23) moves from the worktable (12) toward the pusher (14), the one-way lever (75) contacts the toggle switch (28). Under the action of the toggle switch (28), the one-way lever (75) abuts against the limit plate (76). The one-way lever (75) toggles the toggle switch (28) to rotate, so that the toggle switch (28) rotates from the first direction to the second direction.
