[0028] In order to enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below in conjunction with embodiments. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0029] Such as Figures 1-8As shown in the figure, the specific solution of this embodiment is as follows: A drilling device for special-shaped graphite workpieces includes a machine box body 1. On the machine box body 1, a first clamping mechanism 2 and a second clamping mechanism 3 for clamping the workpiece 4 are provided. Above the workpiece 4, an upper drilling mechanism 5 for drilling the inclined surface thereof is provided. The upper drilling mechanism 5 includes a lifting plate 507. The lifting plate 507 is connected to the telescopic shaft end of the fourth oil cylinder 502. Below the lifting plate 507, movable brackets 516 that can approach or move away from each other are provided. A first electric drill 511 is arranged inside the movable brackets 516. A first drill bit 515 is arranged below the first electric drill 511. Below the workpiece 4, a lower drilling mechanism 6 for drilling the bottom surface thereof is provided.

[0030] More specifically, the machine box body 1 serves as the basic support structure of the entire device, providing an installation platform and positioning reference for each mechanism, ensuring the overall stability of the device and the relative position accuracy between components. The first support seat 201 is used to install and support the first oil cylinder 202, providing a stable base for the fixation of the first oil cylinder 202 and ensuring the smoothness of the telescopic movement of the oil cylinder. The telescopic shaft end of the first oil cylinder 202 pushes the first clamping plate 203 through telescopic movement to achieve the clamping and loosening operations of the workpiece 4. Its telescopic force and stroke are adjustable to adapt to workpieces 4 of different sizes and clamping requirements. The first clamping plate 203 cooperates with the first side clamping plate 204, directly contacts the workpiece 4, and clamps one side of the workpiece 4. An anti-slip structure or soft cushion layer can be arranged on its surface to prevent the workpiece 4 from sliding and being damaged during the clamping process. The first side clamping plate 204 is relatively fixed to the first clamping plate 203, providing support and positioning reference for the other side of the workpiece 4, and jointly acting with the first clamping plate 203 to complete the stable clamping of the workpiece 4.

[0031] As Figure 5 、 Figure 6 、 Figure 7 As shown in the figure, as a preferred mode of the above embodiment, a bearing 517 is arranged between the first drill bit 515 and the inner sleeve ring 521. The rod body 519 circumferentially arranged outside the inner sleeve ring 521 extends into the tube 520. A spring 518 is arranged between the inner sleeve ring 521 and the outer sleeve ring 522 and outside the rod body 519 and the tube 520. The plate body 514 arranged outside the inner sleeve ring 521 is connected to the telescopic shaft end of the fifth oil cylinder 513.

[0032] As Figure 5 、 Figure 6 、 Figure 7 As shown in the figure, as a preferred mode of the above embodiment, the hose 512 arranged on the inner sleeve ring 521 extends upward and is externally connected to a coolant water source. The first guide block 510 arranged at the top of the movable bracket 516 is matched with the first guide rail 509. The movable plate 505 arranged at the top of the movable bracket 516 extends upward through the clearance groove 506 and is connected to the telescopic shaft end of the third oil cylinder 501.

[0033] More specifically, the lifting plate 507 is connected to the telescopic shaft end of the fourth oil cylinder 502. Through the up and down movement of the lifting plate 507, the height adjustment of the entire upper drilling mechanism 5 is driven. The lifting plate 507 provides an installation platform and support for the movable bracket 516, ensuring the stability of the movable bracket 516 during the lifting process.

[0034] The telescopic shaft end of the fourth oil cylinder 502 drives the lifting plate 507 to move up and down, thereby adjusting the height position of the first electric drill 511 to adapt to workpieces 4 of different heights and drilling depth requirements. Its telescopic speed and force can be adjusted according to the drilling process to ensure the smoothness and accuracy of the drilling process.

[0035] The first electric drill 511 is arranged inside the movable bracket 516 and can move closer to or away from each other below the lifting plate 507. Driven by the telescopic shaft end of the third oil cylinder 501, the movement of the movable bracket 516 can change the distance between the first electric drills 511, adapt to different drilling positions and drilling intervals on the inclined surface of the workpiece 4, and realize simultaneous drilling operations at multiple positions.

[0036] The first electric drill 511 serves as the power source for drilling, driving the first drill bit 515 to rotate and perform drilling operations on the inclined surface of the workpiece 4. Its rotation speed and torque can be adjusted according to the material of the graphite workpiece 4 and the drilling requirements to obtain the best drilling effect.

[0037] The first drill bit 515 is in direct contact with the workpiece 4 and is a key component for performing drilling operations. Its shape and size are designed according to the drilling requirements. By rotating and cutting the material of the workpiece 4, the required holes are formed. A bearing 517 is arranged between the first drill bit 515 and the inner sleeve ring 521 to reduce friction and wear during the rotation of the drill bit, improve the service life and rotation accuracy of the drill bit.

[0038] The inner sleeve ring 521 is arranged between the first drill bit 515 and the outer sleeve ring 522. The rod body 519 surrounding its outer circumference extends into the tube 520, forming a structure with relative movement between the outer sleeve ring 522. The plate body 514 on the inner sleeve ring 521 is connected to the telescopic shaft end of the fifth oil cylinder 513. By controlling the fifth oil cylinder 513, the position of the inner sleeve ring 521 can be adjusted, thereby changing the extension length and drilling depth of the first drill bit 515. At the same time, the inner sleeve ring 521 provides a channel for the transportation of coolant. The coolant water source connected by the hose 512 flows to the drill bit through the inner sleeve ring 521 to realize the cooling of the drilling area.

[0039] The bearing 517 is arranged between the first drill bit 515 and the inner sleeve ring 521, which is used to reduce the frictional resistance during the rotation of the first drill bit 515, reduce heat generation, improve the rotation accuracy and stability of the first drill bit 515. The use of the bearing 517 can effectively extend the service life of the first drill bit 515 and ensure the drilling quality.

[0040] The rod body 519 extends into the tube 520 to form a guiding and supporting structure. The cooperation between the rod body 519 and the tube 520 limits the movement direction of the inner sleeve ring 521, enabling it to move smoothly.

[0041] The spring 518 is arranged between the inner sleeve ring 521 and the outer sleeve ring 522 and is located outside the rod body 519 and the tube 520. The elastic action of the spring 518 can buffer the impact force generated during the drilling process to a certain extent, protect the first drill bit 515 and the first electric drill 511, and at the same time can automatically adjust the pressure between the first drill bit 515 and the workpiece 4 to ensure the smooth progress of drilling.

[0042] The plate body 514 is connected to the telescopic shaft end of the fifth oil cylinder 513. Through the telescopic action of the fifth oil cylinder 513, the inner sleeve ring 521 and the first drill bit 515 thereon are driven to move up and down, realizing the precise control of the drilling depth. The control accuracy of the fifth oil cylinder 513 is high, and it can accurately adjust the feed rate of the drill bit according to the requirements of the drilling process.

[0043] The hose 512 and the coolant source hose 512 extend upward and are externally connected to the coolant source to provide continuous coolant supply for the drilling process. The coolant flows through the gap between the inner sleeve ring 521 and the outer sleeve ring 522 and directly acts on the drilling area, taking away the heat generated by the cutting of the first drill bit 515 and the workpiece 4, reducing the temperature of the first drill bit 515, reducing thermal deformation, and improving the drilling accuracy and surface quality.

[0044] The first guide block 510 provided at the top of the movable bracket 516 is matched with the first guide rail 509 to provide guiding and supporting for the movement of the movable bracket 516. The first guide rail 509 limits the movement direction of the movable bracket 516, enabling it to slide smoothly along the guide rail, ensuring the accuracy and stability of the position adjustment of the first electric drill 511.

[0045] The movable plate 505 and the telescopic shaft end of the third oil cylinder 501. The movable plate 505 passes upward through the clearance groove 506 and is connected to the telescopic shaft end of the third oil cylinder 501. The telescopic movement of the third oil cylinder 501 is transmitted to the movable bracket 516 through the movable plate 505, driving the movable brackets 516 to approach or move away from each other to realize the adjustment of the distance between the first electric drills 511. The design of the clearance groove 506 provides space for the movement of the movable plate 505, avoiding interference with other components and ensuring the normal movement of the movable bracket 516.

[0046] As Figure 5 shown, as a preferred mode of the above embodiment, a guide rod 504 is matched and arranged in the bushing 508 provided on the lifting plate 507, and the top of the guide rod 504 is arranged on the bracket 503.

[0047] As Figure 2 、 Figure 3As shown, as a preferred embodiment of the above-described embodiment, the first clamping mechanism 2 includes a first support base 201. A first clamping plate 203 is provided at the end of the telescopic shaft of a first oil cylinder 202 provided on the side of the first support base 201. A first side clamping plate 204 is provided opposite to the first clamping plate 203.

[0048] As Figure 2 , Figure 3 shown, as a preferred embodiment of the above-described embodiment, the second clamping mechanism 3 includes a second support base 301. A second clamping plate 308 is provided at the end of the telescopic shaft of a second oil cylinder 302 provided on the second support base 301. An anti-slip pad 309 is provided on the side of the second clamping plate 308 facing the workpiece 4. The second clamping plate 308 is connected to a slider 306 through a first connecting rod 307. The slider 306 is arranged in a matching manner with a chute 305. Openings 304 are symmetrically provided on the side of the chute 305. A plurality of conveying cylinders 303 are provided in the openings 304. A second side clamping plate 310 is provided opposite to the second clamping plate 308. The second side clamping plate 310 is connected to a third support base 312 through a second connecting rod 311. Both the second clamping plate 308 and the second side clamping plate 310 are inclined.

[0049] As Figure 8 , Figure 9 shown, as a preferred embodiment of the above-described embodiment, the lower drilling mechanism 6 includes a lifting table 604. A sliding seat 612 capable of making a reciprocating linear motion in the horizontal direction is provided on the lifting table 604. A second electric drill 613 is provided on the sliding seat 612. The second drill bit 610 provided on the second electric drill 613 faces the bottom of the workpiece 4. The bottom of the lifting table 604 is connected to the end of the telescopic shaft of a sixth oil cylinder 607.

[0050] As Figure 8 , Figure 9 shown, as a preferred embodiment of the above-described embodiment, a second guide block 605 provided on the side of the lifting table 604 is arranged in a matching manner with a second guide rail 601. A lead screw 603 is provided in a mounting seat 602 on the lifting table 604. The end of the lead screw 603 is connected to the output shaft end of a motor 611. The lead screw 603 is arranged in a matching manner with a lead screw nut 609 provided at the bottom of the sliding seat 612.

[0051] As Figure 8 , Figure 9 shown, as a preferred embodiment of the above-described embodiment, a third guide block 608 provided at the bottom of the lead screw nut 609 is matched with a third guide rail 606.

[0052] The specific working principle of the present invention: When the workpiece 4 is clamped, the special-shaped graphite workpiece 4 is placed on the machine box body 1, and the first clamping mechanism 2 and the second clamping mechanism 3 are started simultaneously. The telescopic shaft end of the first oil cylinder 202 pushes the first clamping plate 203 to cooperate with the first side clamping plate 204 to clamp one side of the workpiece 4; the telescopic shaft end of the second oil cylinder 302 drives the second clamping plate 308 to slide in the chute 305 through the slider 306, playing a role in stabilizing and adjusting. The anti-slip pad 309 on the second clamping plate 308 plays an anti-slip role. The second clamping plate 308 and the second side clamping plate 310 jointly clamp the other side of the workpiece 4. The inclined setting of the second clamping plate 308 and the second side clamping plate 310 can better fit the shape of the workpiece 4 to ensure firm clamping.

[0053] When the upper drilling mechanism 5 works, the telescopic shaft end of the fourth oil cylinder 502 drives the lifting plate 507 to move up and down to adjust the height position of the first electric drill 511. At the same time, the telescopic shaft end of the third oil cylinder 501 drives the movable bracket 516 to approach or move away from each other through the sliding of the movable plate 505 and the first guide block 510 on the first guide rail 509, changing the distance between the first electric drills 511 to adapt to the shape of the inclined surface of the workpiece 4 and the requirements of the drilling position. The first electric drill 511 is started, and the first drill bit 515 rotates to start drilling on the inclined surface of the workpiece 4. The hose 512 on the inner sleeve ring 521 continuously conveys the coolant to the drilling area. The coolant flows out through the gap between the inner sleeve ring 521 and the outer sleeve ring 522 to cool the drill bit and the drilling part, reducing drill bit wear and heat accumulation. The setting of the bearing 517 makes the drill bit rotate more smoothly, reducing vibration and friction. The fifth oil cylinder 513 is driven, and the plate body 514 drives the inner sleeve ring 521 to be adjusted towards the inclined surface of the workpiece 4, prompting the first drill bit 515 to perform force compensation to avoid uneven force.

[0054] When the lower drilling mechanism 6 works, the telescopic shaft end of the sixth oil cylinder 607 drives the lifting table 604 to move up and down to adjust the height of the sliding seat 612. The motor 611 drives the lead screw 603 to rotate. The lead screw 603 cooperates with the lead screw nut 609 at the bottom of the sliding seat 612, so that the sliding seat 612 makes a reciprocating linear motion along the third guide rail 606 in the horizontal direction, thereby driving the second electric drill 613 to move to the designated drilling position on the bottom surface of the workpiece 4. The second electric drill 613 is started, and the second drill bit 610 drills the bottom surface of the workpiece 4.

[0055] Compared with the prior art, the present application has the following advantages: Efficient drilling. By the simultaneous operation of the upper drilling mechanism 5 and the lower drilling mechanism 6, the inclined surface and the bottom surface of the special-shaped graphite workpiece 4 can be quickly drilled, greatly improving the drilling efficiency and shortening the processing cycle.

[0056] Precise punching. Through the precise control of each oil cylinder and electric drill, as well as the mutual cooperation of each moving component, the punching position on the inclined plane can be adjusted, ensuring the processing quality of workpiece 4 and meeting the requirements of high-precision processing.

[0057] Stable clamping. The reasonable design of the first clamping mechanism 2 and the second clamping mechanism 3 provides strong clamping force and good stability, ensuring that workpiece 4 will not displace during the punching process, and improving the reliability and consistency of punching.
