Description

Technical Field

[0001] This invention relates to the technical field of CNC drilling equipment, and in particular to a high-efficiency drilling machine tool. Background Technology

[0002] Drilling machine tools are widely used in general machinery manufacturing, automotive parts production, aerospace component processing and other scenarios. In existing technologies, in fields such as drilling in soil or rock, and mining of oil, gas, water and mineral mud in wells, the processing quality of key components such as drill pipes, casings, and drilling tool joints directly determines drilling efficiency, sealing reliability and operational safety. Among these, drilling (to realize functions such as fluid channels and connection positioning) is the core process of drill tool manufacturing.

[0003] Traditional drilling machines require manual tool changing during the drilling process, which necessitates stopping the machine and impacting drilling efficiency. Furthermore, the possibility of workers changing to the wrong tool during the process leads to non-compliance with standards, increasing manufacturing costs and failing to meet the demands of modern industry for efficient and precise production. Therefore, developing a high-efficiency drilling machine that achieves integrated, high-precision, and rapid processing is urgently needed to improve machining capacity and quality. This will help the industry overcome technical bottlenecks in the precision machining of workpieces and meet the stringent standards of various industries for parts processing.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In this invention, by setting a fixing mechanism, before the drilling machine tool drills the relevant drill bit, the operator places the relevant drill bit on the upper part of two support seats. The two support members first support the relevant drill bit, and then the transmission member one drives the fixing members on both sides to fix the relevant drill bit. Through the action of the two fixing members and the transmission member one, the drilling machine tool can drill the drill bit of different sizes, thus improving the adaptability of the device.

[0020] In this invention, by providing a tool holder, when a tool needs to be replaced, the transmission mechanism drives the placement rack to rotate, causing a tool holder on the outer surface of the placement rack that holds the tool to be replaced to rotate to the side near the limiting hole. Then, the limiting member drives this tool holder to rotate 90 degrees, so that the operator can take the tool placed in its inner cavity. At the same time, by controlling the position of the tool to be replaced by the system, the operator can avoid picking up the wrong tool to a certain extent, which would affect the drilling work of the subsequent drilling mechanism, thus improving the reliability of the device.

[0021] In this invention, by providing a tool changing device and a clamping device, when a tool needs to be changed, the two picking mechanisms can automatically change the tool under the action of the tool changing device, and the drilling machine is in a standby state. After the tool is installed, the drilling operation can be performed again. At the same time, the hole diameter and the tools used by the two drilling mechanisms may be different. Therefore, when one drilling mechanism needs to change the tool, the other drilling mechanism can still operate. This avoids the phenomenon that the operator needs to stop the drilling machine and then restart it to perform the drilling operation, which affects the drilling efficiency.

Detailed Implementation

[0037] 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.

[0038] 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.

[0039] 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.

[0040] In order to fix devices that require drilling, such as Figure 2 and Figure 3 As shown, the fixing mechanism 3 includes a support base 31, which is fixedly installed on the upper end of the base 1. Fixing members 32 are provided on both sides of the upper end of the support base 31. A transmission member 33 for pushing the two fixing members 32 to move is provided on the upper part of the support base 31. A support member 34 is provided on one side of the outer surface of the support base 31.

[0041] Specifically, before the drilling machine drills the relevant drill bit, the operator places the relevant drill bit on the upper part of the two support seats 31. At this time, the two support members 34 first support the relevant drill bit, and then the transmission member 33 drives the fixing members 32 on both sides to fix the relevant drill bit.

[0042] Furthermore, since different drill bits have different diameters, when the support member 34 supports the drill bit, the longitudinal distance between the central axis of the drill bit and the central axis of the drill bit after the fixing members 32 on both sides have fixed the drill bit is relatively large, which is not conducive to the fixing members 32 on both sides fixing the drill bit. Therefore, the height of the support member 34 can be manually adjusted by the staff.

[0043] To house the cutting tools required for drilling by the drilling mechanism 2, so that operators can change the tools, such as... Figure 4 and Figure 5 As shown, the tool holder 4 includes a mounting base 41, which is fixedly mounted on the upper end of the base 1. A mounting frame 42 is provided on the upper end of the mounting base 41. A limiting hole 421 is opened on one side of the outer surface of the mounting frame 42. A placement rack 43 is provided in the middle of the inner cavity of the mounting frame 42. Multiple tool placement pieces 44 are rotatably mounted on the outer surface of the placement rack 43. A transmission mechanism 45 is provided on one side of the outer surface of the mounting frame 42. A transmission handle 451 is provided at the output end of the transmission mechanism 45. Two transmission wheels 452 are provided on the end face of the transmission handle 451. A limiting piece 46 is provided on the other side of the outer surface of the mounting frame 42. The limiting piece 46 is adapted to be used with the multiple tool placement pieces 44.

[0044] Furthermore, such as Figure 6 and Figure 7As shown, the placement rack 43 includes a placement plate 431, which is rotatably mounted on the inner surface of the mounting frame 42. A transmission ring 432 is provided on the outer surface of the placement plate 431 near the transmission mechanism 45. Multiple transmission grooves 433 are provided on the outer surface of the transmission ring 432, and the multiple transmission grooves 433 are adapted to the transmission handle 451.

[0045] Specifically, during the process of the transmission mechanism 45 driving the transmission handle 451 to rotate, firstly, a transmission wheel 452 on the end face of the transmission handle 451 enters the inner cavity of a transmission groove 433. This transmission wheel 452 moves towards the inner side of the inner cavity of the transmission groove 433 as the transmission handle 451 rotates. Then, driven by the transmission handle 451, it moves towards the outer side of the inner cavity of the transmission groove 433. During this process, the transmission ring 432 is driven to rotate. Then, after the transmission mechanism 45 drives the transmission handle 451 to continue rotating at a certain angle, another transmission wheel 452 on the end face of the transmission handle 451 enters... The transmission mechanism 45 enters the inner cavity of the adjacent transmission groove 433 and repeats the action of the previous transmission wheel 452, thereby driving the placement frame 43 to run. At the same time, since each transmission groove 433 corresponds to a tool placement piece 44, when a tool needs to be replaced, the transmission mechanism 45 rotates counterclockwise or clockwise. Through the cooperation of the two transmission wheels 452 and the placement frame 43, the corresponding transmission groove 433 is pushed closer to the side of the limiting hole 421. At this time, the tool to be replaced is in the tool replacement position. Then, the limiting piece 46 pushes out the tool to be replaced through the tool placement piece 44.

[0046] Furthermore, when a tool needs to be replaced, the transmission mechanism 45 drives the placement rack 43 to rotate, causing a tool placement piece 44 on the outer surface of the placement rack 43 to rotate to the side near the limiting hole 421. Then, the limiting piece 46 drives the tool placement piece 44 to rotate 90 degrees so that the operator can take the tool placed in its inner cavity.

[0047] To make it easier for staff to take things, such as Figure 8 As shown, the limiting member 46 includes a cylinder 461, which is fixedly installed on the outer surface of the mounting frame 42. The output end of the cylinder 461 is provided with a slider 462, which is slidably installed on the outer surface of the mounting frame 42. One end of the slider 462 near the tool placement member 44 extends into the interior of the mounting frame 42, and the slider 462 is adapted to the tool placement member 44 for use.

[0048] For placing the knives, such as Figure 9As shown, the tool holder 44 includes a holder cylinder 441, which is rotatably mounted on the outer surface of the holder 43. A push handle 442 is rotatably mounted on the upper part of the outer surface of the holder cylinder 441. A spring is fixedly mounted on the lower part of the outer surface of the push handle 442 and fixedly mounted on the upper part of the outer surface of the holder cylinder 441. A limit block 443 is provided on the lower end face of the push handle 442. The limit block 443 is adapted to the mounting handle for mounting the tool. A limit wheel 444 is provided on the side of the outer surface of the holder cylinder 441 away from the push handle 442. The limit wheel 444 is adapted to the U-shaped block 463.

[0049] 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.

[0050] 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.

[0051] 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, the tool changing method needs to be improved, 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.

[0052] 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.

[0053] 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.

[0054] Specifically, when a tool needs to be replaced, the drilling mechanisms 2 on both sides move to the corresponding positions, and the tool to be replaced in the tool holder 4 rotates to one side of the limiting hole 421. Under the action of the limiting member 46, the tool placement member 44 that holds the tool to be replaced rotates 90 degrees. At this time, the transmission member 2 51 drives the clamping device 6 to rotate 90 degrees through the transmission rod 52, so that the clamping device 6 clamps the tool to be replaced on the drilling mechanism 2 and the tool holder 4. Then, the cylinder 2 53 retracts, so that the cylinder 2 53 drives the clamping device 6 to remove the tool from the drilling mechanism 2 and the tool holder 4 through the transmission rod 52. During this process, when the clamping device 6 picks up the tool placed on the tool placement member 44, the clamping device 6 will drive the driven member 54 to release the tool from the tool placement member 44, so that the clamping device 6 can take the tool out of the inner cavity of the tool placement member 44.

[0055] Furthermore, after the clamping device 6 removes the tools from the punching mechanism 2 and the tool holder 4 under the action of the second cylinder 53, the second transmission component 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 switched. Then the second cylinder 53 outputs, so that the tools in the two picking mechanisms 6 are respectively placed into the corresponding tool placement component 44 and the punching mechanism 2, so that the punching mechanism 2 and the tool placement component 44 fix the replaced tools. After that, the second cylinder 53 retracts again. During this process, the clamping device 6 can detect whether the tool holder 4 and the punching mechanism 2 have finished fixing the tools. 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 action of the tool changing device 5.

[0056] Furthermore, the fixing of the cutting tool by the punching mechanism 2 can be achieved through relevant components and programs, without the need for manual control by the operator. This is existing technology and will not be described in detail in this manual.

[0057] To facilitate the retrieval of the cutting tool placed on the tool holder 4 using the clamping device 6, such as Figure 11As shown, the driven member 54 includes a sector frame 541, which is fixedly installed on the outer surface of the transmission member 51. An arc rod 543 is provided in the middle of 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 to the push handle 442. The middle part of the push plate 542 is slidably connected to the outer surface of the arc rod 543. A spring 544 is wound around the outer surface of the arc rod 543. The upper and lower ends of the spring 544 are fixedly connected to the outer surface of the push plate 542 and the inner surface of the sector frame 541, respectively.

[0058] In order to retrieve the cutting tool placed on the tool holder 4, and simultaneously remove the cutting tool originally placed on the drilling mechanism 2, as follows: Figure 12 As shown, the clamping device 6 includes a mounting plate 61, which is fixedly mounted on the output end of the transmission rod 52. Two push wheels 611 are provided on the outer surface of the mounting plate 61 near the tool changing device 5. Both push wheels 611 are adapted to be used with the push plate 542. Clamping mechanisms 62 are provided at both ends of the mounting plate 61. The two clamping mechanisms 62 are installed in opposite directions. A hydraulic mechanism 64 is provided in the middle of the mounting plate 61. A cylinder 63 is provided on the outer surface of the hydraulic mechanism 64 away from the tool changing device 5.

[0059] Specifically, when a tool needs to be replaced, the tool changing device 5 drives the mounting plate 61 to rotate 90 degrees so that the clamping mechanisms 62 on both sides can clamp the tools on the drilling mechanism 2 and the tool holder 4 respectively. During this process, the clamping mechanisms 62 on both sides are in a relaxed state. At the same time, as the mounting plate 61 rotates, a push wheel 611 on the surface of the mounting plate 61 gradually approaches the tool holder 4 and contacts the surface of the push plate 542. The push wheel 611 drives the push plate 542 to rotate downward, so that the push plate 542 contacts the push handle 442 and pushes the push handle 442 to rotate, so that the limit block 443 releases the restriction on the tool.

[0060] Furthermore, when the push wheel 611 pushes the push plate 542 to rotate downward, the push plate 542 will drive the second spring 544 to stretch downward. When the transmission rod 52 pushes the mounting plate 61 outward to remove the tool from the drilling mechanism 2 and the tool holder 4, the push wheel 611 no longer contacts the surface of the push plate 542. At this time, the push plate 542 returns to its initial position under the pull of the second spring 544.

[0061] Furthermore, when the mounting plate 61 drives the two clamping mechanisms 62 to rotate 90 degrees, the two clamping mechanisms 62 are positioned on both sides of the tool holder 4 and the drilling mechanism 2 where the tool to be replaced needs to be placed. Then, the cylinder 63 pulls the hydraulic mechanism 64 to change the two clamping mechanisms 62 from a relaxed state to a clamped state. At this time, the clamping mechanisms 62 on both sides clamp the tools on the tool holder 4 and the drilling mechanism 2. After that, the tool changing device 5 pushes the clamping device 6 outward. During this process, the clamping device 6 removes the tools from the tool holder 4 and the drilling mechanism 2.

[0062] Furthermore, after the clamping device 6 removes the cutting tools from the tool holder 4 and the drilling mechanism 2, the tool changing device 5 drives the clamping device 6 to rotate 180 degrees, so that the positions of the cutting tools clamped by the clamping mechanisms 62 on both sides are changed. Then, the tool changing device 5 drives the clamping device 6 to move inward, so that the cutting tools on the two clamping mechanisms 62 are placed in the inner cavities of the corresponding drilling mechanism 2 and the tool placement piece 44 respectively.

[0063] Furthermore, after the two clamping mechanisms 62 place the tool on the tool holder 4 and the drilling mechanism 2, the tool changing device 5 will slightly push the clamping device 6 to move outward. During this process, it can be detected whether the tool to be replaced is installed in place. After the detection is completed, the cylinder 63 pushes the hydraulic mechanism 64 to release the clamping state of the two clamping mechanisms 62 on the tool. After that, the tool changing device 5 drives the clamping device 6 back to the initial position.

[0064] Furthermore, when the tool changing device 5 drives the clamping device 6 to rotate 180 degrees, the tool changing device 5 pushes the clamping device 6 outward at this time, thereby preventing the push wheel 611 from contacting the driven member 54.

[0065] To achieve automatic tool changing, such as Figure 13 As shown, 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 changing device 5. The extended end of the hydraulic oil frame 641 extends into the interior of the mounting plate 61. A connecting pipe 642 fixedly installed inside the mounting plate 61 is provided at the extended end of the hydraulic oil frame 641. Both the upper and lower ends of the connecting pipe 642 are connected to two hydraulic push rods 643 through hydraulic pipes. The extended rods of the connecting pipes 642 on both sides extend to the outside of the mounting plate 61.

[0066] Furthermore, the output end of cylinder 3 63 extends into the inner cavity of hydraulic oil frame 641, and the output end of cylinder 3 63 is fixedly connected to the piston in the inner cavity of hydraulic oil frame 641.

[0067] Furthermore, such as Figure 14As shown, the clamping mechanism 62 includes a first clamping block 621 and a second clamping block 622. The first clamping block 621 is fixedly installed on the end face of the mounting plate 61. The inner wall of the first clamping block 621 is slidably connected to the extension rod of the hydraulic push rod 643. The second clamping block 622 is fixedly connected to the end faces of the two corresponding hydraulic push rods 643. A clamping arc plate 623 is slidably installed on the inner surface of both the first clamping block 621 and the second clamping block 622. Multiple anti-slip particles are provided on the inner surface of the clamping arc plate 623. The middle of the first clamping block 621 and the second clamping block 622... Each part is slidably mounted with multiple mounting rods 624. L-shaped rods 625 are provided on both sides of the outer surface of the multiple mounting rods 624. The multiple L-shaped rods 625 are fixedly connected to the end faces of the two clamping arc plates 623 respectively. Springs are provided on both sides of the outer surface of the multiple mounting rods 624, and the multiple springs are fixedly connected to the surfaces of clamping block one 621 and clamping block two 622 respectively. A sensor 626 is provided on the middle end face of clamping block one 621. The installation position of the sensor 626 is sufficient to detect the displacement of the clamping arc plate 623.

[0068] Specifically, when the clamping mechanism 62 needs to clamp the tool, the cylinder 63 pulls the hydraulic oil frame 641, causing the hydraulic oil in the inner cavity of the hydraulic push rods 643 on both sides to enter the inner cavity of the hydraulic oil frame 641 through the connecting pipe 642. At this time, the clamping blocks 622 in the two clamping mechanisms 62 move towards the side of the mounting plate 61 under the action of the hydraulic push rods 643, thereby completing the clamping of the tool. Conversely, the clamping mechanism 62 changes from the clamping state to the loose state.

[0069] Furthermore, after the tools on the two clamping mechanisms 62 are respectively placed into the drilling mechanism 2 and the tool holder 4, the tool changing device 5 will slightly push the clamping device 6 to move outward. During this process, since the clamping arc plates 623 on clamping block 1 621 and clamping block 2 622 are the parts that clamp the tools, when the tool changing device 5 slightly pushes the clamping device 6 to move outward, the positions of the two clamping arc plates 623 remain unchanged. When clamping block 1 621 and clamping block 2 622 change position with mounting plate 61, multiple mounting rods 624 connected by multiple L-shaped rods 625 on clamping block 1 621 and clamping block 2 622 will slide on the inner wall of clamping block 1 621 and clamping block 2 622. During this process, the springs on both sides of the multiple mounting rods 624 will be compressed or stretched, generating corresponding elastic potential energy. This elastic potential energy is used to check whether the fixture is installed in place. If the tool is not pulled out by this elastic potential energy, it is installed in place, and vice versa.

[0070] Furthermore, 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 sensor 626 will transmit a signal (the sensor 626 can be a displacement sensor), indicating that the tool is installed in place. If the sensor does not transmit a signal, the clamping arc plate 623 does not move, which indicates that the tool is not installed in place.

[0071] In summary, the specific implementation method is as follows: 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 drilling mechanisms 2 on both sides move to the corresponding positions. At the same time, the tool holder 4 rotates the tool to be replaced to one side of the limiting hole 421, and the limiting member 46 causes the tool placement member 44 to rotate 90 degrees. Then, the transmission member 51 drives the clamping device 6 to rotate 90 degrees through the transmission rod 52, so that the clamping device 6 picks up the tool to be replaced on the drilling mechanism 2 and the tool holder 4. The clamping mechanism is engaged, and then cylinder 53 retracts, causing cylinder 53 to drive the clamping device 6 via transmission rod 52 to remove the tools from the punching mechanism 2 and the tool holder 4. Then, transmission component 51 drives the clamping device 6 to rotate 180 degrees via transmission rod 52. At this time, the positions of the two tools on the clamping device 6 are switched. Then, cylinder 53 outputs, causing the tools in the two picking mechanisms 6 to be placed into the corresponding tool placement parts 44 and the punching mechanism 2 respectively, so that the punching mechanism 2 and the tool placement parts 44 fix the replaced tools. Finally, the clamping device 6 releases the fixation of the two tools, and then the clamping device 6 returns to the initial position under the drive of the tool changing device 5.

[0072] It should be noted that the specific installation methods, circuit layout and connection methods of the drilling mechanism 2, transmission component 33, transmission mechanism 45 and cylinder 461 used in the above embodiment 1 and the transmission component 51, cylinder 53 and cylinder 63 used in embodiment 2, as well as their control methods, are all conventional designs in the prior art, and will not be described in detail in this invention.
