Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1: As Figure 1 As shown, this embodiment discloses a high-efficiency drilling machine tool, including a base 1. Drilling mechanisms 2 are slidably installed on both sides of the upper end of the base 1. Two fixing mechanisms 3 are provided in the middle of the upper end of the base 1. Two tool holders 4 are provided near one side of the upper end of the base 1.

[0022] Specifically, before the drilling machine drills the relevant drill bit, the operator places the relevant drill bit on the upper part of the fixing mechanism 3, and then drills the two ends of the relevant drill bit through the drilling mechanisms 2 on both sides. During this process, when it is necessary to change different drilling tools, the operator can remove the tool to be replaced from the drilling mechanism 2, and then remove the tool to be installed from the tool holder 4 and install it on the drilling mechanism 2.

[0023] In order to fix devices that require drilling, such as Figure 2 and Figure 3As shown, the fixing mechanism 3 comprises a support seat 31 fixedly installed at the upper end of the base 1, both sides of the upper end of the support seat 31 are provided with fixing members 32, and the upper portion of the support seat 31 is provided with a transmission member I 33 for driving the two fixing members 32 to move, and one side of the outer surface of the support seat 31 is provided with a support member 34.

[0024] Specifically, before the drilling machine drills the relevant drill, the staff places the relevant drill on the upper portion of the two support seats 31, at this time, the two support members 34 first support the relevant drill, and then the transmission member I 33 drives the two fixing members 32 to fix the relevant drill.

[0025] Further, the diameters of different drills are different, so when the support member 34 supports the drill, the longitudinal distance deviation of the central axis of the drill at this time is relatively large after the two fixing members 32 fix the drill, which is not conducive to the fixing of the drill by the two fixing members 32, so the height of the support member 34 can be manually adjusted by the staff.

[0026] In order to place the cutter required by the drilling mechanism 2 when drilling, so that the staff can replace the cutter, as shown in Figure 4 and Figure 5 As shown, the cutter holder 4 comprises a mounting seat 41 fixedly installed at the upper end of the base 1, the upper end of the mounting seat 41 is provided with a mounting frame I 42, one side of the outer surface of the mounting frame I 42 is provided with a limiting hole 421, the inner cavity of the mounting frame I 42 is provided with a placing rack 43, the outer surface of the placing rack 43 is rotatably installed with a plurality of cutter placing members 44, one side of the outer surface of the mounting frame I 42 is provided with a transmission mechanism 45, the output end of the transmission mechanism 45 is provided with a transmission handle 451, the end face of the transmission handle 451 is provided with two transmission wheels 452, the other side of the outer surface of the mounting frame I 42 is provided with a limiting member 46, and the limiting member 46 is used in matching with the plurality of cutter placing members 44.

[0027] Further, as shown in Figure 6 and Figure 7 As shown, the placing rack 43 comprises a placing plate 431 rotatably installed on the inner cavity surface of the mounting frame I 42, the outer surface of the placing plate 431 is provided with a transmission ring 432 near one side of the transmission mechanism 45, the outer surface of the transmission ring 432 is provided with a plurality of transmission grooves 433, and the plurality of transmission grooves 433 are used in matching with the transmission handle 451.

[0028] Specifically, in the process that the transmission mechanism 45 drives the transmission handle 451 to rotate, first, a transmission wheel 452 on the end surface of the transmission handle 451 enters the inner cavity of a transmission groove 433, the transmission wheel 452 moves towards the inner side of the inner cavity of the transmission groove 433 when the transmission handle 451 rotates, and then moves towards the outer side of the inner cavity of the transmission groove 433 under the driving of the transmission handle 451, in this process, the transmission ring 432 is driven to rotate, then, another transmission wheel 452 on the end surface of the transmission handle 451 enters the inner cavity of the adjacent transmission groove 433 after the transmission mechanism 45 drives the transmission handle 451 to continue rotating by a certain angle, the action of the previous transmission wheel 452 is repeated, so that the transmission mechanism 45 drives the placing frame 43 to operate, and since each transmission groove 433 corresponds to a tool placing piece 44, when a tool needs to be replaced, the transmission mechanism 45 rotates counterclockwise or clockwise, the corresponding transmission groove 433 is pushed to the side close to the limiting hole 421 through the cooperation of the two transmission wheels 452 and the placing frame 43, at this time, the tool to be replaced is in the position for tool replacement, then the limiting piece 46 pushes out the tool to be replaced through the tool placing piece 44.

[0029] Further, when a tool needs to be replaced, the transmission mechanism 45 drives the placing frame 43 to rotate, so that a tool placing piece 44 storing a tool to be replaced on the outer surface of the placing frame 43 rotates to the side close to the limiting hole 421, then the limiting piece 46 drives the tool placing piece 44 to rotate by 90 degrees, so that the staff can take out the tool placed in the inner cavity.

[0030] In order to facilitate the staff to take out the tool, as shown in the drawings, Figure 8 The limiting piece 46 comprises a cylinder one 461, the cylinder one 461 is fixedly installed on the outer surface of the mounting frame one 42, the output end of the cylinder one 461 is provided with a sliding block 462, the sliding block 462 is slidingly installed on the outer surface of the mounting frame one 42, one end of the sliding block 462 close to the tool placing piece 44 extends to the inside of the mounting frame one 42, and the sliding block 462 is matched with the tool placing piece 44 for use.

[0031] In order to place the tool, as shown in the drawings, Figure 9 The tool placing piece 44 comprises a placing cylinder 441, the placing cylinder 441 is rotationally installed on the outer surface of the placing frame 43, a push handle 442 is rotationally installed on the outer surface of the placing cylinder 441, a spring one is fixedly installed on the outer surface of the placing cylinder 441 and located at the lower part of the outer surface of the push handle 442, a limiting block one 443 is arranged on the lower end surface of the push handle 442, the limiting block one 443 is matched with the mounting handle of the tool for use, a limiting wheel one 444 is arranged on the side of the outer surface of the placing cylinder 441 away from the push handle 442, and the limiting wheel one 444 is matched with the U-shaped block 463 for use.

[0032] Specifically, when the placement rack 43 rotates, the limiting wheels 444 on the multiple tool placement pieces 44 will sequentially enter the inner cavity of the U-shaped block 463. When the limiting wheel 444 on the target tool placement piece 44 enters the inner cavity of the U-shaped block 463, the placement rack 43 stops rotating. At this time, the cylinder 461 retracts and drives the U-shaped block 463 to run through the slider 462. During this process, the U-shaped block 463 drives the placement cylinder 441 to rotate 90 degrees through the limiting wheel 444, so that the placement cylinder 441 extends out of the inner cavity of the mounting frame 42 from the limiting hole 421, so that the staff can take the tool placed in the inner cavity of the placement cylinder 441. At the same time, by controlling the tool replacement through the system, the staff can avoid picking the wrong tool that needs to be replaced to a certain extent.

[0033] Furthermore, when the tool is placed into the inner cavity of the placement cylinder 441, the inclined surface on the limiting block 443 will not prevent the tool from entering the inner cavity of the placement cylinder 441. However, when it is necessary to remove the tool from the inner cavity of the placement cylinder 441, the push handle 442 needs to be pressed to lift the limiting block 443. Only after the limiting block 443 releases the restriction on the tool can the tool be removed from the inner cavity of the placement cylinder 441.

[0034] Example 2: This example further improves the tool changing device 5 based on Example 1. During the drilling process of the drilling mechanism 2, the operator needs to manually install the drilling tool placed on the tool holder 4 onto the drilling mechanism 2. This process requires the machine to be stopped, affecting drilling efficiency. Therefore, it is necessary to improve the tool changing method, such as... Figure 1 As shown, a tool changing device 5 is provided on the upper part of the outer surface of both tool holders 4, and a clamping device 6 is provided on the side of the output end of the two tool changing devices 5 that is close to each other.

[0035] Specifically, during the drilling process of the drilling mechanism 2, the operator needs to manually install the drilling tool placed on the tool holder 4 onto the drilling mechanism 2. This process requires the machine to be stopped, which affects the drilling efficiency. Therefore, when it is necessary to change the tool, the tool changing device 5 drives the clamping device 6 to replace the tool on the drilling mechanism 2 and the tool holder 4.

[0036] To facilitate the retrieval of the cutting tools placed on the tool holder 4 by the two retrieval mechanisms 6, and simultaneously remove the cutting tools originally placed on the punching mechanism 2, such as... Figure 10 As shown, the tool changing device 5 includes a second transmission component 51. A transmission rod 52 is slidably mounted on the lower part of the second transmission component 51. Both ends of the transmission rod 52 extend to the outside of the second transmission component 51. A second cylinder 53 is provided at the lower end of the second transmission component 51. The extended end of the second cylinder 53 is rotatably connected to one side of the outer surface of the transmission rod 52. A driven component 54 is provided on the side of the outer surface of the second transmission component 51 near the clamping device 6.

[0037] Specifically, when the tool needs to be replaced, the punching mechanism 2 on both sides moves to the corresponding position, and the tool to be replaced in the tool holder 4 is rotated to one side of the limiting hole 421, and the tool placing part 44 placing the tool to be replaced is rotated 90 degrees under the action of the limiting part 46. At this time, the transmission part two 51 drives the clamping device 6 to rotate 90 degrees through the transmission rod 52, so that the clamping device 6 clamps the tools on the punching mechanism 2 and the tool holder 4 that need to be exchanged, then the cylinder two 53 is retracted, so that the cylinder two 53 drives the clamping device 6 to take off the tools on the punching mechanism 2 and the tool holder 4 through the transmission rod 52. During this process, when the clamping device 6 takes the tool placed on the tool placing part 44, the clamping device 6 drives the driven part 54 to release the fixing state of the tool placing part 44 to the tool, so that the clamping device 6 takes the tool out of the inner cavity of the tool placing part 44.

[0038] Further, after the clamping device 6 takes off the tools on the punching mechanism 2 and the tool holder 4 under the action of the cylinder two 53, the transmission part two 51 drives the clamping device 6 to rotate 180 degrees through the transmission rod 52. At this time, the positions of the two tools on the clamping device 6 are exchanged, and then the cylinder two 53 is output. The tools in the two clamping devices 6 are respectively placed into the corresponding tool placing part 44 and the inside of the punching mechanism 2, so that the punching mechanism 2 and the tool placing part 44 fix the replaced tools. Then the cylinder two 53 is retracted again. During this process, the clamping device 6 can detect whether the tool holder 4 and the punching mechanism 2 are fixed to the tool, and then the clamping device 6 releases the fixing state of the two tools. Finally, the clamping device 6 returns to the initial position under the drive of the tool changing device 5.

[0039] Further, the fixing of the tool by the punching mechanism 2 can be realized by related components and procedures without manual control by the staff. This is prior art, and the present specification will not be described in detail.

[0040] In order to cooperate with the clamping device 6 to take the tool placed on the tool holder 4, as shown in Figure 11 The driven part 54 includes a sector frame 541 fixedly installed on the outer surface of the transmission part two 51. An arc-shaped rod 543 is arranged in the inner cavity of the sector frame 541. A push plate 542 is rotatably installed in the inner cavity of the sector frame 541. The push plate 542 is adapted for use with the push handle 442. The middle part of the push plate 542 is slidably connected with the outer surface of the arc-shaped rod 543. A spring two 544 is wound around the outer surface of the arc-shaped rod 543. The upper and lower ends of the spring two 544 are fixedly connected with the outer surface of the push plate 542 and the inner cavity surface of the sector frame 541 respectively.

[0041] In order to take the tool placed on the tool holder 4, and take off the tool originally placed on the punching mechanism 2, as shown in Figure 12As shown, the clamping device 6 comprises a mounting plate 61 fixedly mounted on the output end of the transmission rod 52, the outer surface of the mounting plate 61 is provided with two push wheels 611 close to one side of the tool changing device 5, the two push wheels 611 are adapted for use with the push plate 542, both ends of the mounting plate 61 are provided with clamping mechanisms 62, the mounting directions of the two clamping mechanisms 62 are opposite, the middle part of the mounting plate 61 is provided with a hydraulic mechanism 64, the outer surface of the hydraulic mechanism 64 is provided with a cylinder three 63 away from one side of the tool changing device 5.

[0042] Specifically, when it is necessary to replace the tool, the tool changing device 5 drives the mounting plate 61 to rotate 90 degrees so that the clamping mechanisms 62 on both sides clamp the tools on the punching mechanism 2 and the tool holder 4 respectively, in this process, the clamping mechanisms 62 on both sides are in a relaxed state, at the same time, in the process of rotating the mounting plate 61, one of the push wheels 611 on the surface of the mounting plate 61 gradually approaching the tool holder 4 will be in contact with the surface of the push plate 542, so that the push wheel 611 drives the push plate 542 to rotate downward, so that the push plate 542 is in contact with the push handle 442 and drives the push handle 442 to rotate, so that the limiting block one 443 releases the limitation on the tool.

[0043] Further, when the push wheel 611 pushes the push plate 542 to rotate downward, the push plate 542 will drive the spring two 544 to stretch downward, when the transmission rod 52 pushes out the mounting plate 61 to the outside to take out the tool from the punching mechanism 2 and the tool holder 4, the push wheel 611 is no longer in contact with the surface of the push plate 542, at this time, the push plate 542 returns to the initial position under the pulling of the spring two 544.

[0044] Further, after the mounting plate 61 drives the two clamping mechanisms 62 to rotate 90 degrees, the two clamping mechanisms 62 are on both sides of the tools in the tool holder 4 and the punching mechanism 2 that need to be replaced, then the cylinder three 63 drives the hydraulic mechanism 64 to change the two clamping mechanisms 62 from the relaxed state to the clamped state, at this time, the clamping mechanisms 62 on both sides clamp the tools on the tool holder 4 and the punching mechanism 2, then the tool changing device 5 pushes the clamping device 6 outward, in this process, the clamping device 6 takes down the tools on the tool holder 4 and the punching mechanism 2.

[0045] Further, after the clamping device 6 takes down the tools on the tool holder 4 and the punching mechanism 2, the tool changing device 5 drives the clamping device 6 to rotate 180 degrees, so that the positions of the tools clamped by the clamping mechanisms 62 on both sides are exchanged, then the tool changing device 5 drives the clamping device 6 to move inward, so that the tools on the two clamping mechanisms 62 are placed in the inner cavities of the corresponding punching mechanism 2 and tool placing part 44 respectively.

[0046] Further, when the two clamping mechanisms 62 place the tool on the tool holder 4 and the punching mechanism 2, the tool changer 5 slightly pushes the clamping device 6 to move outward, and in this process, it can be detected whether the replaced tool is installed in place. After the detection is completed, the cylinder three 63 pushes the hydraulic mechanism 64 to make the two clamping mechanisms 62 release the clamping state of the tool, and then the tool changer 5 drives the clamping device 6 to return to the initial position.

[0047] Further, when the tool changer 5 drives the clamping device 6 to rotate 180 degrees, because the tool changer 5 pushes the clamping device 6 outward at this time, the pushing wheel 611 does not contact the driven part 54.

[0048] In order to realize automatic tool changing, as shown in the figure, Figure 13 The hydraulic mechanism 64 includes a hydraulic oil frame 641, which is fixedly installed on the outer surface of the mounting plate 61 away from the tool changer 5. The extending end of the hydraulic oil frame 641 extends to the inside of the mounting plate 61. The extending end of the hydraulic oil frame 641 is provided with a connecting pipe 642 fixedly installed in the inside of the mounting plate 61. The upper and lower ends of the connecting pipe 642 are connected with two hydraulic push rods 643 through hydraulic pipes. The extending rods of the connecting pipes 642 located on both sides extend to the outside of the mounting plate 61.

[0049] Further, the output end of the cylinder three 63 extends into the inner cavity of the hydraulic oil frame 641, and the output end of the cylinder three 63 is fixedly connected with the piston in the inner cavity of the hydraulic oil frame 641.

[0050] Further, as shown in the figure, Figure 14 The clamping mechanism 62 includes a clamping block one 621 and a clamping block two 622. The clamping block one 621 is fixedly installed on the end face of the mounting plate 61. The inner wall of the clamping block one 621 is slidingly connected with the extending rod of the hydraulic push rod 643. The clamping block two 622 is fixedly connected with the end face of the corresponding two hydraulic push rods 643. The inner side surfaces of the clamping block one 621 and the clamping block two 622 are slidingly installed with clamping arc plates 623. The inner side surfaces of the clamping arc plates 623 are provided with a plurality of anti-skid particles. The middle parts of the clamping block one 621 and the clamping block two 622 are slidingly installed with a plurality of mounting rods 624. The outer surfaces of the plurality of mounting rods 624 are provided with L-shaped rods 625 on both sides. The plurality of L-shaped rods 625 are respectively fixedly connected with the end faces of the two clamping arc plates 623. The outer surfaces of the plurality of mounting rods 624 are provided with springs on both sides, and the plurality of springs are respectively fixedly connected with the surfaces of the clamping block one 621 and the clamping block two 622. The middle end face of the clamping block one 621 is provided with an inductor 626. The installation position of the inductor 626 ensures that the displacement of the clamping arc plate 623 can be detected.

[0051] Specifically, when the clamping mechanism 62 needs to clamp the tool, the cylinder three 63 pulls the hydraulic oil frame 641, so that the hydraulic oil in the inner cavity of the hydraulic push rod 643 on both sides enters the inner cavity of the hydraulic oil frame 641 through the connecting pipe 642. At this time, the clamping block two 622 in the two clamping mechanisms 62 moves to the side of the mounting plate 61 under the action of the hydraulic push rod 643, so as to complete the clamping of the tool. Conversely, the clamping mechanism 62 changes from the clamped state to the relaxed state.

[0052] Further, after the tools on the two clamping mechanisms 62 are respectively placed into the inside of the punching mechanism 2 and the tool holder 4, the tool changing device 5 slightly pushes the clamping device 6 to move outward. During this process, since the clamping arc plate 623 on the clamping block one 621 and the clamping block two 622 is the part for clamping the tool, when the tool changing device 5 slightly pushes the clamping device 6 to move outward, the position of the two clamping arc plates 623 does not change. When the clamping block one 621 and the clamping block two 622 change the position of the mounting plate 61, the multiple mounting rods 624 connected by the multiple L-shaped rods 625 on the clamping block one 621 and the clamping block two 622 will slide on the inner wall of the clamping block one 621 and the clamping block two 622. During this process, the springs on both sides of the multiple mounting rods 624 will be compressed or stretched under force, generating corresponding elastic potential energy. The elastic potential energy is used to check whether the clamp is installed in place. If the tool is not pulled out by the elastic potential energy, it is installed in place. Conversely, it is not installed in place.

[0053] Further, when the tool changing device 5 slightly pushes the clamping device 6 to move outward, if the clamping arc plate 623 moves under force, the inductor 626 will transmit a signal (the inductor 626 can be a displacement sensor), indicating that the tool is installed in place. If the inductor does not transmit a signal, the clamping arc plate 623 does not move, indicating that the tool is not installed in place.

[0054] In summary, the specific embodiment is that before the drilling machine drills the relevant drill, the staff places the relevant drill on the upper part of the fixing mechanism 3, and then drills both ends of the relevant drill through the two sides of the drilling mechanism 2. In this process, when different drilling knives need to be replaced, the two sides of the drilling mechanism 2 move to the corresponding position, and the knife holder 4 rotates the knife to be replaced to one side of the limiting hole 421, and the limiting piece 46 makes the knife placing piece 44 rotate 90 degrees. After that, the transmission member two 51 drives the clamping device 6 to rotate 90 degrees through the transmission rod 52, so that the clamping device 6 clamps the knives on the drilling mechanism 2 and the knife holder 4 that need to be replaced. Then, the cylinder two 53 retracts, so that the cylinder two 53 drives the clamping device 6 to take off the knives on the drilling mechanism 2 and the knife holder 4 through the transmission rod 52. Then the transmission member two 51 drives the clamping device 6 to rotate 180 degrees through the transmission rod 52. At this time, the positions of the two knives on the clamping device 6 are exchanged. After that, the cylinder two 53 outputs, so that the knives in the two clamping devices 6 are respectively placed into the corresponding knife placing piece 44 and the inside of the drilling mechanism 2, so that the drilling mechanism 2 and the knife placing piece 44 fix the replaced knives. Finally, the clamping device 6 releases the fixing state of the two knives, and then the clamping device 6 is driven by the knife changing device 5 to return to the initial position.
