[0007] By adopting the above technical solution, the drilling machine for plate processing realizes the automation and efficiency of plate drilling through integrated design. Specifically, its effects include: the driving part drives the drill bit to rotate and the lifting part controls the up and down movement of the drill bit, and the precise control of the control component realizes the automatic up and down movement and drilling action of the drill bit, reduces manual operation and improves work efficiency. By utilizing the design of the limit plate and the limit cavity, the plate to be drilled can be accurately positioned at the drilling position, and the plate is automatically pressed against the abutment column under the action of the transmission component, ensuring the accuracy and stability of the drilling. After the drill bit completes the drilling, the power belt and the push block cooperate to realize the automatic transportation of the plate, reduce the tediousness of manual handling, and improve the fluency and efficiency of the production line. The design of the control component enables the next adjacent plate to be drilled to move into the limit cavity after the plate with the completed drilling is separated from the limit cavity, greatly improving the drilling efficiency.

[0009] By adopting the above technical solution and the specific control component design, i.e., the combination of the control motor, the control column and the support column, the material loading is convenient and the drilling efficiency is improved. Specifically, the control motor realizes the online drive of the load-bearing plate and the plate through the threaded connection with the control column, so that after the previous plate is drilled, the next plate to be drilled can move into the limit cavity.

[0010] Optionally, the pressing member is a pressing block, the pressing block is slidably disposed on the outer wall of the drill bit, and the pressing block is inclined to form a sliding surface; When the pressing block moves upward, the control button slides on the sliding surface, and the pressing block presses the control button; The mounting frame is provided with an upper push block and a lower push block, the upper push block is located above the control button, the lower push block is located below the control button, an upper push surface is formed on the upper push block, and a lower push surface is formed on the lower push block; When the pressing block slides on the upper push surface, the pressing block slides to be misaligned with the control button, and when the pressing block slides on the lower push surface, the pressing block slides to be in the same vertical direction as the control button.

[0011] By adopting the above technical solution, through the design of the pressing member, that is, the combination of the pressing block and the sliding surface, the accuracy and reliability of pressing the control button are improved. Specifically: when the pressing block moves upward, the control button slides on the sliding surface, ensuring the smoothness and stability of the pressing action, and avoiding control errors caused by uneven pressing. Through the design of the upper push block and the lower push block, the position of the pressing block is adjusted to ensure that when the drill moves downward, the pressing block is misaligned with the control button, and when the drill moves upward, the pressing block can press the control button.

[0012] Optionally, the transmission assembly includes a transmission block, a transmission column and a transmission spring; The transmission column slides up and down on the abutment column, the transmission spring is arranged in the abutment column, and the transmission spring drives the abutment column to protrude upward to the outside of the transmission column; The transmission block is arranged on the outer wall of the drill bit, and the transmission block is located directly above the transmission column. The transmission block pushes the transmission column to slide downward on the abutment column, and at this time, the transmission spring enters a compressed state.

[0013] By adopting the above technical solution and the specific transmission component design, i.e., the combination of the transmission block, the transmission column and the transmission spring, the precise driving of the abutment column and the automatic tightening of the plate are realized. Specifically, the transmission column slides downward under the action of the transmission block, driving the abutment column to tighten the plate, thus ensuring the stability and accuracy during the drilling process.

[0014] Optionally, the power component is a power motor, which is arranged on the top of the first limiting plate. The first limiting plate rotates and is symmetrically provided with a rotating shaft for the power belt to be mounted on. The output shaft of the power motor is connected to one of the rotating shafts and is coaxially arranged.

[0015] By adopting the above technical solution, the power performance and stability of the drilling machine are further improved by specifying that the power part is the power motor. Specifically, the power motor provides strong power support for the cyclic rotation of the power belt through the connection between the output shaft and the rotating shaft. The symmetrically arranged rotating shaft and the power belt are connected end to end to ensure the stability and reliability during the power transmission process.

[0016] Optionally, the opening and closing member is an opening and closing button, the opening and closing button is arranged in the abutment column, and the opening and closing button is electrically connected to the power motor; The transmission spring surrounds the opening and closing button. When the transmission column presses the opening and closing button, the power motor is in a closed state. When the opening and closing button returns to a state before being pressed, the power motor enters a started state.

[0017] By adopting the above technical solution and the specific opening and closing parts design, namely the opening and closing button and the transmission column design, the precise control of the starting state of the power motor is achieved. Specifically: when the transmission column presses the opening and closing button, the power motor is in the closed state, which reduces the accidental rotation of the power belt during the drilling process; when the opening and closing button returns to the state before being pressed, the power motor automatically starts to prepare for the conveying of the plate.

[0027] The following is combined with Figure 1-6 This application is described in further detail.

[0028] The embodiment of the present application discloses a drilling machine for plate processing.

[0029] The inventor of the present application has found that the drilling machine in the prior art needs to manually remove the plate and replace it with a new plate to be drilled after the plate is drilled, which not only increases the labor intensity, but also greatly affects the overall production efficiency. To this end, the present application mainly adopts the following scheme to achieve the effect of improving the drilling efficiency. The following is a further detailed description of the present application.

[0030] See also Figure 1 and Figure 2 A drilling machine for plate processing provided in an embodiment of the present application includes a machine platform 1, a mounting frame 2, a drill bit 21, a driving member, a lifting member, a bearing plate 12 and a limiting plate 3.

[0031] Among them, see Figure 2 and Figure 3 The machine 1 is placed on the ground and fixed by anchor bolts. The mounting frame 2 is fixed on the top of the machine 1. The mounting frame 2 is slidable up and down and is provided with a mounting seat 27. The drill bit 21 is detachably fixed on the mounting seat 27. A drilling cutter is detachably fixed at the bottom of the drill bit 21. When in use, the mounting seat 27 moves up and down, so that the drill bit 21 drives the drilling cutter to move up and down to drill holes in the plate.

[0032] The driving member is arranged on the mounting frame 2, and the driving member drives the drill bit 21 to rotate. The driving member is a driving motor 22, and the driving motor 22 is fixedly mounted on the mounting seat 27. The output shaft of the driving motor 22 rotates on the mounting seat 27, and the output shaft of the driving motor 22 is fixedly connected with the drill bit 21 and is coaxially arranged. When the driving motor 22 is started, the drill bit 21 is driven to rotate, so that the drilling cutter on the drill bit 21 drills holes in the plate.

[0033] The lifting member is arranged on the mounting frame 2, and the lifting member drives the drill bit 21 to move up and down. Specifically, the lifting member is a lifting hydraulic cylinder 23, and the lifting hydraulic cylinder 23 includes a hydraulic cylinder body, an oil pipe and a pressure regulating valve. The hydraulic cylinder body is fixed on the mounting frame 2, and the piston rod of the hydraulic cylinder body is fixed on the top of the mounting seat 27, which is used to drive the mounting seat 27 to move up and down. In the initial state, the mounting seat 27 is located near the lifting hydraulic cylinder 23. The oil pipe connects the hydraulic cylinder body and the hydraulic system, and the pressure regulating valve is used to adjust the working pressure of the hydraulic cylinder body. The oil pipe adopts a pressure-resistant hose with good high-pressure resistance, and the pressure regulating valve adopts a digital pressure regulating valve, which can achieve precise pressure regulation. The combination of the three ensures that the lifting member can smoothly drive the drill bit 21 to move up and down. A control panel is provided on the machine 1 to control the opening and closing of the lifting hydraulic cylinder 23 and the driving motor 22. When the drilling plate is supplemented, the lifting hydraulic cylinder 23 and the driving motor 22 are first suspended through the control panel. When the supplement is completed, the lifting hydraulic cylinder 23 and the driving motor 22 are started through the control panel.

[0034] The machine 1 is formed with a receiving groove 11, which is located directly below the drill bit 21, and the carrying plate 12 slides up and down in the receiving groove 11. A feeding port is formed on one side wall of the machine 1, and the feeding port is connected with the receiving groove 11. The plate to be drilled enters the receiving groove 11 through the feeding port, and then the plate is stacked up and down and placed on the top of the carrying plate 12, and the top end surface of the top plate in the receiving groove 11 is in the same plane as the top end surface of the machine 1.

[0035] See also Figure 1 and Figure 2 The limit plate 3 is arranged on the top of the machine 1. The limit plate 3 includes a first limit plate 31 and a second limit plate 32. The first limit plate 31 and the second limit plate 32 are respectively fixed on the top of the machine 1. The length of the first limit plate 31 is greater than the width of the receiving groove 11. The first limit plate 31 and the second limit plate 32 are perpendicular to each other. A limit cavity 33 is formed between the first limit plate 31 and the second limit plate 32. The first limit plate 31 and the second limit plate 32 are respectively on the same vertical plane with the groove wall of the receiving groove 11 directly below. When drilling, the vertical side walls of the plate to be drilled on both sides are respectively abutted against the first limit plate 31 and the second limit plate 32 to limit the plate to be drilled, thereby improving the positioning accuracy and drilling efficiency of the plate.

[0036] See also Figure 2 and Figure 3The drilling machine also includes a control assembly 4, which includes a control motor 41, a control column 42 and a support column 43. The support column 43 is fixed at the middle position at the bottom of the carrier plate 12, the control column 42 is threadedly connected to the support column 43 and is coaxially arranged, and the control column 42 extends away from the carrier plate 12 and protrudes out of the support column 43. The control motor 41 is embedded and fixed in the machine 1 and is located on the bottom wall of the accommodating groove 11. The output shaft of the control motor 41 is connected and fixed to the control column 42 and is coaxially arranged. The control motor 41 adopts a servo motor. When in use, the control motor 41 is started to drive the control column 42 to rotate. At this time, the support column 43 drives the carrier plate 12 to move upward, pushing the plate to be drilled upward into the limit cavity 33.

[0037] A control button 24 is fixedly mounted on the mounting frame 2, and the control button 24 is located at a position away from the top of the machine 1. The control button 24 is electrically connected to the control motor 41. When the control button 24 is pressed, the control motor 41 enters a start state. The drill bit 21 is provided with a pressing member, which is a pressing block 211. The pressing block 211 is slidably arranged on the outer wall of the drill bit 21 along a horizontal direction, and a sliding surface 2111 is formed on one side of the top of the pressing block 211. When the pressing block 211 moves upward and approaches the initial position, the control button 24 slides on the sliding surface 2111. At this time, the pressing block 211 presses the control button 24. Then, when the control button 24 slides to the side of the pressing block 211 facing the control button 24, the control button 24 remains in a pressed state.

[0038] An upper push block 25 and a lower push block 26 are fixedly connected to the mounting frame 2. The upper push block 25 is located above the control button 24, and the lower push block 26 is located below the control button 24. An upper push surface 251 is formed on the upper push block 25, and a lower push surface 261 is formed on the lower push block 26. When the pressing block 211 slides upward to a position close to the initial position, the pressing block 211 slides on the upper push surface 251, and at this time, the upper push block 25 pushes the pressing block 211 to slide to a position displaced from the control button 24. When the mounting seat 27 slides downward to a position close to the top of the machine 1, the pressing block 211 slides on the lower push surface 261, and at this time, the lower push block 26 pushes the pressing block 211 to slide to a state in the same vertical direction as the control button 24. The matching structure of the pressing block 211 and the control button 24 ensures that the control motor 41 can be accurately triggered when the drill bit 21 moves upward.

[0039] See also Figure 3 and Figure 4 The receiving groove 11 is formed with mounting grooves on the vertical groove walls on both sides facing the first limiting plate 31 and the second limiting plate 32. The mounting grooves are located near the notch of the receiving groove 11 and are connected to the receiving groove 11. The machine 1 is slidably connected with a correction column 13, which is opposite to the limiting plate 3 (the limiting plate 3 is Figure 1The machine 1 is provided with a driving spring 14, which is installed in the mounting groove. One end of the driving spring 14 abuts against the end of the correction column 13, and the other end abuts against the groove wall on the side of the mounting groove away from the groove opening. When the driving spring 14 is elastically released, the correction column 13 is driven to abut against the side wall of the plate to be drilled at the top of the receiving groove 11, and pushes the plate to be drilled to abut against the groove wall of the receiving groove 11 just below the limiting plate 3, so as to correct the position of the plate and further improve the drilling accuracy. The bottom of the correction column 13 is inclined to form a driving surface 131. When the plate to be drilled at the top of the receiving groove 11 slides upward into the limiting cavity 33, the next adjacent plate to be drilled follows and slides upward to the position of the groove opening of the receiving groove 11. At this time, the plate to be drilled slides on the driving surface 131, driving the correction column 13 to reset, so that the correction column 13 can correct the next adjacent plate to be drilled.

[0040] See also Figure 2 and Figure 3 Abutment columns 311 are provided on the first limiting plate 31. There are two abutment columns 311 which slide up and down on the first limiting plate 31. The drill bit 21 is located between the two abutment columns 311, and the abutment columns 311 slide up and down in the limiting cavity 33 to tightly abut the plate to be drilled.

[0041] See also Figure 3 and Figure 5 The outer wall of the drill bit 21 is provided with a transmission assembly, and the transmission assembly includes a transmission block 51, a transmission column 52 and a transmission spring 5. The abutment column 311 is formed with an abutment groove that penetrates upward in the vertical direction to the outside of the abutment column 311, and the transmission column 52 slides up and down in the abutment groove. The transmission spring 5 is installed in the abutment groove, the top of the transmission spring 5 abuts against the top of the transmission column 52, and the bottom of the transmission spring 5 abuts against the bottom groove wall of the abutment groove. When the transmission spring 5 is elastically released, the transmission spring 5 drives the abutment column 311 to protrude upward to the outside of the transmission column 52. The transmission block 51 is fixedly installed on the outer wall of the drill bit 21, and the transmission block 51 extends to just above the transmission column 52. When the drill bit 21 moves downward to the plate to be drilled in the limit cavity 33, the transmission block 51 first abuts against the top of the transmission column 52, and then transmits power through the transmission spring 5, so as to push the abutment column 311 to move downward to abut against the top of the plate to be drilled in the limit cavity 33, fix the plate, and reduce the possibility of the plate shaking during drilling. During the drilling process of the drill bit 21, the transmission spring 5 is continuously compressed to increase the degree of pressing of the abutment column 311 on the plate, and at the same time reduce the possibility of the drill bit 21 encountering resistance when moving downward.

[0042] See also Figure 5 and Figure 6The first limit plate 31 is rotatably connected with a rotating shaft, and there are two rotating shafts that are symmetrically arranged, one of which is located near the second limit plate 32, and the other is located away from the second limit plate 32. The first limit plate 31 is provided with a power belt 312 connected end to end, and the power belt 312 is sleeved on the outer circumference of the two rotating shafts. The power belt 312 is slidably passed through the first limit plate 31, and a clearance groove is formed on the side of the first limit plate 31 facing the plate, and the power belt 312 slides in the clearance groove, reducing the possibility that the power belt 312 protrudes from the first limit plate 31 and affects the position of the plate.

[0043] The outer wall of the power belt 312 is fixedly connected with a push block 313, and there are two push blocks 313 and they are symmetrically arranged. The push block 313 is located near the receiving groove 11. When drilling, the push block 313 is located between the abutment column 311 and the notch of the receiving groove 11. In the initial state, the two push blocks 313 are located on opposite sides of the two rotation axes, and the two push blocks 313 and the two rotation axes are on the same straight line.

[0044] The first limiting plate 31 is provided with a power member for driving the power belt 312 to rotate cyclically, so that a push block 313 adjacent to the second limiting plate 32 moves to the position of another push block 313. At this time, the push block 313 close to the second limiting plate 32 pushes the plate with the drilled hole out of the limiting cavity 33, so that the next adjacent plate to be drilled can move upward into the limiting cavity 33 (the limiting cavity 33 is Figure 3 (marked in middle).

[0045] See also Figure 3 and Figure 5 The power part is a power motor 314, which is fixed on the top of the first limit plate 31. The output shaft of the power motor 314 is connected to one of the rotating shafts and is coaxially arranged. When the power motor 314 is started, it drives the rotating shaft to rotate, so that the power belt 312 enters a circulating rotation state. The power motor 314 adopts a high-efficiency permanent magnet motor with a high energy efficiency ratio, and the rotating shaft adopts a high-strength material with good supporting performance. The combination of the power motor 314 and the rotating shaft ensures the efficient rotation of the power belt 312.

[0046] An opening and closing member is provided on the abutting column 311 . When the drill bit 21 moves away from the abutting column 311 , the opening and closing member controls the power motor 314 to start, so that the power belt 312 rotates, and the pushing block 313 pushes the plate away from the limiting cavity 33 .

[0047] The opening and closing part is an opening and closing button 315, which is fixed to one of the abutting columns 311 and is located in the abutting groove. The opening and closing button 315 is electrically connected to the power motor 314. The transmission spring 5 surrounds the opening and closing button 315. When the transmission column 52 drives the abutting column 311 to abut against the plate, the transmission column 52 presses the opening and closing button 315. At this time, the power motor 314 is in a closed state. In the process of the drill bit 21 moving away from the plate, the transmission spring 5 is elastically released, pushing the transmission column 52 away from the opening and closing button 315. At this time, the opening and closing button 315 returns to the state before being pressed, and the power motor 314 enters the starting state, driving the drilled plate away from the limiting cavity 33, and when the plate moves away from the limiting cavity 33, the friction force transmitted to the next adjacent plate to be drilled is subjected to the correction column 13 (the correction column 13 is in Figure 4 The offset of the marked).

[0048] The implementation principle of a drilling machine for plate processing in the embodiment of the present application is as follows: When drilling, the lifting hydraulic cylinder 23 drives the mounting seat 27 to move downward, so that the drill bit 21 is close to the plate. When the drill bit 21 is close to the plate, the abutment column 311 abuts the plate to fix the plate, and then the drilling cutter on the drill bit 21 drills the hole. After the drilling is completed, the transmission column 52 moves away from the opening and closing button 315, so that the power motor 314 starts and drives the rotating shaft to rotate. At this time, the power belt 312 enters a circular motion, driving a push block 313 adjacent to the second limit plate 32 to move to the position of another push block 313, so that the push block 313 close to the second limit plate 32 pushes the plate with the completed drilling to the outside of the limit cavity 33. When the drilling plate is away from the limit cavity 33 and the drill bit 21 is close to the hydraulic lifting cylinder position, the pressing block 211 presses the control button 24, so that the control motor 41 enters the starting state, drives the carrier plate 12 to move upward, moves the plate at the top of the receiving slot 11 to the limit cavity 33 and then stops, and the plate with the completed drilling is uniformly recovered after leaving the limit cavity 33. Afterwards, the drilling machine drills the next plate to be drilled according to the same steps until all the plates to be drilled in the receiving slot 11 are drilled.
