[0020] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the present invention provides a drilling device for metal casting, as Figures 1-10As shown in the figure, the drilling equipment for metal casting includes: a workbench 1 and a placing seat 2 rotatably installed on the workbench 1 for placing casting parts; a drill bit 4 arranged above the placing seat 2 for drilling the casting parts; a laser pointer 5 arranged on one side of the drill bit 4 for positioning the casting parts; a collection box 6 arranged below the chip discharge port of the workbench 1 for collecting chips; a group of push plates 7 slidably arranged on the workbench 1 and located below the placing seat 2, and the group of push plates 7 is used to scrape the chips into the collection box 6; a driving mechanism arranged on the workbench 1 for driving the drill bit 4 to rotate.

[0022] In this embodiment, the operator places the metal casting part to be drilled on the placing seat 2, uses the laser emitted by the laser pointer 5 to position the casting part, and after determining the drilling position, starts the driving mechanism to drive the drill bit 4 to rotate at a high speed. As the drill bit 4 descends, the drill bit 4 performs drilling operations on the casting part.

[0023] During the drilling process, the high-speed rotating drill bit 4 will generate a large amount of metal chips, and these chips are scattered on the surface of the workbench 1. When it is necessary to clean the chips, a group of push plates 7 slide relative to each other on the workbench 1. During the sliding process, the chips on the workbench surface are pushed and scraped to the chip discharge port of the workbench 1, and the chips fall into the collection box 6 below the chip discharge port through the chip discharge port, thereby completing the collection and cleaning of the chips. By using the laser emitted by the laser pointer 5 to position the casting part, it can help the operator accurately place the casting part in the correct position, ensure the accuracy of the drilling position, and by promptly scraping the chips into the collection box 6 through the push plates 7, it can prevent the chips from accumulating on the workbench 1, ensure the stable placement of the casting part, and reduce the risk of drill bit deviation or breakage.

[0024] In a further preferred embodiment of the present invention, a hydraulic cylinder 8 for adjusting the height of the drill bit 4 is fixedly installed on the top of the workbench 1, a fixing component 9 is arranged on the hydraulic cylinder 8, a first electric telescopic rod 11 is fixedly installed at the bottom of the fixing component 9, and a support plate 3 is installed on the first electric telescopic rod 11.

[0025] In this embodiment, before performing the drilling operation, the operator adjusts the height of the drill bit 4 through the hydraulic cylinder 8 according to factors such as the thickness of the casting part and the required drilling depth. The hydraulic cylinder 8 can accurately control the lifting of the drill bit 4 and adjust it to a suitable position to prepare for the subsequent drilling. While the drill bit 4 is rotating at a high speed, the first electric telescopic rod 11 extends downward at a uniform speed, driving the support plate 3 and the related structures thereon (such as the drill bit 4) to move downward, thereby realizing the drilling operation of the drill bit 4 on the casting part. Through the setting of the hydraulic cylinder 8, the height of the drill bit 4 can be flexibly adjusted according to different casting parts and drilling requirements, and it can adapt to various drilling operations of different specifications and requirements, enhancing the versatility and applicability of the equipment.

[0026] In a further preferred embodiment of the present invention, the driving mechanism includes: a connecting member 12 rotatably mounted on the support plate 3, the connecting member 12 being detachably connected to the drill bit 4; a first motor 13 fixedly mounted on the top of the support plate 3; a set of first bevel gears 14 respectively fixedly sleeved on the coupling output shaft of the first motor 13 and the rotating shaft of the connecting member 12, the set of first bevel gears 14 being meshed with each other; and a protective cover 15 covering the first motor 13 and the set of first bevel gears 14.

[0027] In this embodiment, when drilling operation is required, the first motor 13 is started, and the coupling of the first motor 13 begins to rotate, driving the first bevel gear 14 thereon to rotate. Since the two first bevel gears 14 are meshed with each other, the first bevel gear 14 on the rotating shaft of the connecting member 12 will also rotate accordingly, thereby driving the connecting member 12 to rotate. Because the drill bit 4 is detachably connected to the connecting member 12, the rotation of the connecting member 12 will drive the drill bit 4 to rotate at a high speed, providing power for the drilling operation. The protective cover 15 covers the first motor 13 and the set of first bevel gears 14, playing a protective role to prevent external dust, debris, etc. from entering and affecting the normal operation of the equipment, and at the same time ensuring the safety of the operator. Through the structural design of the first motor 13, a set of meshing first bevel gears 14 and the connecting member 12, the stable and reliable transmission of power from the first motor 13 to the drill bit 4 is achieved, which can ensure that the drill bit 4 rotates at a stable speed, thereby improving the quality and efficiency of the drilling operation. By adopting a detachable connection method between the drill bit 4 and the connecting member 12, when the drill bit 4 is worn, damaged or different specifications of drill bits need to be replaced according to different drilling requirements, the operator can replace it conveniently and quickly, improving the maintainability and flexibility of the equipment.

[0028] In a further preferred embodiment of the present invention, a bidirectional screw 16 is rotatably mounted on the top of the workbench 1, the bidirectional screw 16 is threadedly connected to a set of the push plates 7, and an arc-shaped plate 17 is arranged above the bidirectional screw 16, the arc-shaped plate 17 being slidably connected to a set of the push plates 7.

[0029] In this embodiment, when it is necessary to clean the chips on the workbench 1, the linkage mechanism starts to work and drives the bidirectional screw 16 to rotate. Since the bidirectional screw 16 is threadedly connected to a set of push plates 7, during the rotation of the bidirectional screw 16, according to the principle of screw drive, a set of push plates 7 will be driven to slide relatively. Driven by the bidirectional screw 16, a set of push plates 7 slide relatively and move on the tabletop of the workbench 1, pushing the scattered metal chips to the chip discharge port of the workbench 1, so that the chips fall into the collection box 6 below through the chip discharge port, completing the chip cleaning work. The arc-shaped plate 17 is arranged above the bidirectional screw 16 and is slidably connected to a set of push plates 7. During the process of the push plates 7 moving to clean the chips, the arc-shaped plate 17 plays a protective role, which can prevent the chips from falling on the bidirectional screw 16 and avoid the chips from affecting the screw drive between the bidirectional screw 16 and the push plates 7, ensuring the normal operation of the bidirectional screw 16 and the push plates 7. By driving the bidirectional screw 16 to rotate through the linkage mechanism, and then driving a set of push plates 7 to slide relatively, the chips on the workbench 1 can be quickly and effectively cleaned into the collection box 6, improving the efficiency of chip cleaning and reducing the workload of manual cleaning. Through the protective design of the arc-shaped plate 17, it prevents the chips from falling on the bidirectional screw 16 and avoids problems such as jamming and wear caused by the chips entering the screw drive part, ensuring the smoothness of the screw drive between the bidirectional screw 16 and the push plates 7.

[0030] In a further preferred embodiment of the present invention, a linkage mechanism for driving the bidirectional screw 16 to rotate is provided on the workbench 1. The linkage mechanism includes: a support plate 18 fixedly installed on the workbench 1; first sprockets 19 respectively arranged on the support plate 18 and the bidirectional screw 16, and a first chain 20 is sleeved on the two first sprockets 19; a rack 21 fixedly installed on one side of the fixed component 9; a driven gear 22 rotatably installed on one side of the support plate 18, and the driven gear 22 meshes with the rack 21; second sprockets 23 respectively fixedly sleeved on the rotating shafts of the driven gear 22 and the first sprocket 19 located on the support plate 18; a second chain 24 sleeved on the two second sprockets 23.

[0031] In this embodiment, when drilling operations are carried out and the height of the drill bit 4 needs to be adjusted, the hydraulic cylinder 8 drives the fixed component 9 to adjust the height. Since the rack 21 is fixedly installed on one side of the fixed component 9, the rack 21 will move synchronously with the fixed component 9. During the movement of the rack 21, it meshes with the driven gear 22 rotatably installed on one side of the support plate 18, thereby driving the driven gear 22 to rotate. The driven gear 22 drives the second sprocket 23 and the second chain 24 to rotate. The power is transmitted to the first sprocket 19 on the support plate 18 through the second chain 24, causing the first sprocket 19 to rotate. The rotation of the first sprocket 19 drives the first sprocket 19 on the bidirectional screw 16 to rotate through the first chain 20, and finally the bidirectional screw 16 rotates. Thus, when the drill bit 4 moves downward, a set of push plates 7 move relatively away from each other; when the drill bit 4 moves upward, a set of push plates 7 move relatively closer to each other to push the chips into the collection box 6. The up-and-down movement of the drill bit 4 is linked to the relative sliding of the push plates 7 through the linkage mechanism. While the drill bit 4 is performing drilling feed (up-and-down movement), the push plates 7 are automatically driven to clean the chips, eliminating the need for an additional drive device to control the movement of the push plates 7, improving the working efficiency and automation level of the equipment. By using the power source for adjusting the height of the drill bit 4 (the hydraulic cylinder 8 drives the fixed component 9 to move) as the driving power for the push plates 7 to clean the chips, there is no need to add an additional power source, simplifying the equipment structure.

[0032] In a further preferred embodiment of the present invention, an annular plate 25 is sleeved on the placement seat 2. The annular plate 25 is used to assist the chips to be discharged into the collection box 6. A magnet plate 28 for adsorbing and positioning the casting is installed on the top of the placement seat 2.

[0033] In this embodiment, during the drilling operation, the drill bit 4 rotates at a high speed to generate metal chips that scatter on the workbench 1. Since the annular plate 25 is sleeved on the placement seat 2 and the annular plate 25 is arranged in a cylindrical shape, it can play a certain guiding role for the chips, guiding the chips to move towards the chip discharge port of the workbench 1 and assisting the chips to be smoothly discharged into the collection box 6 below the chip discharge port. When placing a casting with ferromagnetic material on the placement seat 2, the magnet plate 28 installed on the top of the placement seat 2 will generate a magnetic force to adsorb the casting, making the casting firmly adsorbed on the placement seat 2. Through the auxiliary effect of the annular plate 25, the chips are more likely to be discharged into the collection box 6 along its guiding direction, reducing the residue of the chips on the workbench 1, improving the efficiency and effect of chip cleaning, avoiding the adverse effects of chip accumulation on the drilling operation, and further enhancing the positioning stability of the casting on the placement seat 2 through the adsorption effect of the magnet plate 28 on the casting with ferromagnetic material in combination with the positioning function of the laser pen 5.

[0034] In a further preferred embodiment of the present invention, a second motor 26 is fixedly installed at the bottom of the workbench 1. Second bevel gears 27 are fixedly sleeved on the coupling shaft of the second motor 26 and the rotating shaft of the placement seat 2, and the two second bevel gears 27 are meshed with each other.

[0035] In this embodiment, when multi-directional drilling operations need to be performed on a casting (such as a flange), the second motor 26 fixedly installed at the bottom of the workbench 1 is started. The coupling shaft of the second motor 26 starts to rotate, driving the second bevel gear 27 fixedly sleeved thereon to rotate. Since a second bevel gear 27 is also fixedly sleeved on the rotating shaft of the placement seat 2, and the two second bevel gears 27 are meshed with each other, the second bevel gear 27 on the rotating shaft of the placement seat 2 will rotate accordingly, thereby driving the placement seat 2 to rotate. When the placement seat 2 rotates, the casting (such as a flange) adsorbed and positioned thereon by the magnet plate 28 will also rotate accordingly, facilitating the drill bit 4 to drill holes at different positions of the casting. Taking flange drilling as an example, usually 6 - 8 threaded holes need to be drilled on the flange. The traditional method may require repositioning and fixing the flange multiple times to complete the drilling operations for all holes. However, by driving the placement seat 2 to rotate through the second motor 26, the flange only needs to be placed on the placement seat 2 once, and different positions of the flange can be conveniently drilled by rotating the placement seat 2, greatly improving the drilling efficiency and saving time and labor costs.

[0036] In a further preferred embodiment of the present invention, a fixing mechanism for fixing the casting is provided on the workbench 1. The fixing mechanism includes: a bidirectional electric guide rail 29 installed on the top of the workbench 1; an arc-shaped clamping block 30 provided on the output block of the bidirectional electric guide rail 29 for clamping and fixing the casting; and an anti-slip pad 31 installed on the inner side of the arc-shaped clamping block 30.

[0037] In this embodiment, when the casting is placed on the placement seat 2 of the workbench 1 and preliminarily adsorbed and positioned by the magnet plate 28, and more stable fixation of the casting is required for drilling operations. At this time, the bidirectional electric guide rail 29 installed on the top of the workbench 1 is started. The output block of the bidirectional electric guide rail 29 will drive the arc-shaped clamping block 30 provided thereon to move towards the casting, so that the arc-shaped clamping block 30 clamps and fixes the casting. The anti-slip pad 31 installed on the inner side of the arc-shaped clamping block 30 can increase the friction with the casting, further preventing the casting from shifting during the drilling process.

[0038] When the angle adjustment of the casting is required (for example, by driving the placement seat 2 to rotate through the second motor 26 to change the position of the casting so as to drill holes at different positions), the output block of the bidirectional electric guide rail 29 is controlled to move in the reverse direction, driving the arc-shaped clamping block 30 away from the casting, so that the casting is in a freely rotatable state. After the second motor 26 completes the angle adjustment of the casting, the output block of the bidirectional electric guide rail 29 is controlled to move again, so that the arc-shaped clamping block 30 clamps and fixes the casting again for subsequent drilling operations. The arc-shaped clamping block 30 can closely fit the casting, and cooperate with the anti-slip pad 31 to provide a large frictional force, effectively preventing the casting from displacing due to the impact force of the drill bit 4 during the drilling process, ensuring the accuracy and quality of the drilling, and improving the stability of the drilling operation.

[0039] In a further preferred embodiment of the present invention, the fixing assembly 9 includes: a mounting plate, a fixing plate, a round rod, and a second electric telescopic rod 32. The mounting plate is mounted on the hydraulic cylinder 8. The fixing plate is disposed on one side of the mounting plate and fixedly connected to the first electric telescopic rod 11. The round rod is fixedly installed on one side of the mounting plate and slidably connected to the fixing plate. The second electric telescopic rod 32 is fixedly installed on the top of the mounting plate, and the output rod of the second electric telescopic rod 32 is fixedly connected to the fixing plate.

[0040] In this embodiment, when drilling operations need to be performed on castings of different sizes, due to the different sizes of the castings, the drilling positions may need to be adjusted left and right. At this time, the second electric telescopic rod 32 fixedly installed on the top of the mounting plate is started, and the output rod of the second electric telescopic rod 32 will perform telescopic movement. Since the output rod of the second electric telescopic rod 32 is fixedly connected to the fixing plate, and the fixing plate is slidably connected to the mounting plate through the round rod, the telescopic movement of the output rod of the second electric telescopic rod 32 will drive the fixing plate to slide left and right along the round rod. Also, because the fixing plate is fixedly connected to the first electric telescopic rod 11, and the first electric telescopic rod 11 drives the drill bit 4 to move up and down for drilling, the left and right movement of the fixing plate realizes the left and right adjustment of the position of the drill bit 4, so as to be able to adapt to the drilling requirements of castings of different sizes at different positions. By driving the fixing plate to move through the second electric telescopic rod 32 to adjust the position of the drill bit 4, the equipment can flexibly handle the drilling operations of castings of different sizes without the need to replace the equipment or perform complex structural adjustments.

[0041] In a further preferred embodiment of the present invention, a counterweight 33 is fixedly installed on the top of the mounting plate, and the counterweight 33 is used to reduce the bending moment borne by the hydraulic cylinder 8.

[0042] In this embodiment, through the counterweight 33, the bending moment borne by the hydraulic cylinder 8 is reduced, which can reduce the stress concentration and fatigue damage of the hydraulic cylinder 8 during the working process, reduce the risk of the hydraulic cylinder 8 malfunctioning or being damaged, and thus extend the service life of the hydraulic cylinder 8.

[0043] In order to further improve the use effect of this device, in addition to the above solution, this solution also has the following embodiments: In another embodiment of the present invention, a connecting plate 34 for isolating chips is provided at the bottom of the support plate 3. A chute 36 is opened on one side of the connecting plate 34. A slide bar 37 is fixedly installed in the chute 36. A slider 38 is slidably sleeved on the slide bar 37. A baffle 35 is fixedly installed on the slider 38.

[0044] In this embodiment, during the drilling process, the generated chips will be blocked by the connecting plate 34 and the baffle 35. The connecting plate 34 is arranged at the bottom of the support plate 3, playing a certain role in isolation to prevent the chips from splashing randomly to other areas. After the baffle 35 contacts the top of the casting, it will maintain a relative position relationship with the top of the casting as the drilling progresses, further restricting the diffusion range of the chips. Finally, under the combined action of the connecting plate 34 and the baffle 35, the chips will be more likely to be discharged into the collection box 6 along a predetermined direction (such as guided to the chip discharge port of the workbench 1). By setting the connecting plate 34 and the baffle 35, the random splashing of chips during the drilling process is effectively prevented, and the chips are avoided from scattering on other parts of the equipment.

[0045] In another embodiment of the present invention, a material full reminder mechanism is provided on the collection box 6. The material full reminder mechanism includes: a pressing plate 39 slidably installed in the collection box 6; a connecting rod 40 fixedly installed on one side of the collection box 6; a connecting block 41 and a return spring 42 sleeved on the connecting rod 40, the connecting block 41 being located at the top of the return spring 42; a connecting plate 43 fixedly installed on the support rod of the pressing plate 39, the connecting plate 43 being fixedly connected to the connecting block 41; a switch device 44 fixedly installed at the bottom of the workbench 1; a contact rod 45 fixedly installed on one side of the connecting block 41 for turning on the switch device 44.

[0046] In this embodiment, during the drilling operation, the chips are continuously discharged into the collection box 6 and accumulate on the pressing plate 39. As the chips increase, the weight borne by the pressing plate 39 gradually increases. When the weight exceeds the elastic force of the return spring 42, the pressing plate 39 will slide downward along the inner wall of the collection box 6. When the pressing plate 39 slides downward, it will drive the connecting plate 43 and the connecting block 41 to slide synchronously, and will compress the return spring 42 during the sliding process, causing the return spring 42 to be compressed.

[0047] When the connecting block 41 slides down to a certain position, the contact rod 45 will come into contact with the switch device 44 fixedly installed at the bottom of the workbench 1. After the switch device 44 is triggered, it will emit a signal to the control system. After receiving the signal emitted by the switch device 44, the control system will prompt the staff in a suitable manner (such as sound alarm, light prompt, or displaying information on the operation interface, etc.) that the collection box 6 is full and needs to be cleaned in time. Through the material full prompt mechanism, the accumulation situation of the chips in the collection box 6 can be monitored in real time. When the collection box 6 is almost full, a prompt signal will be sent in time to avoid the chips overflowing from the collection box 6, ensuring the cleanliness of the working environment. At the same time, the staff can clean the collection box 6 in time according to the prompt, without frequently checking the status of the collection box 6, saving time and labor costs, and improving the overall efficiency of the drilling operation.

[0048] In another embodiment of the present invention, a U-shaped plate 46 is fixedly installed on one side of the collection box 6. An anti-slip layer is provided inside the U-shaped plate 46. An L-shaped plate 47 is fixedly installed at the bottom of the workbench 1. The L-shaped plate 47 is slidably connected to the U-shaped plate 46.

[0049] In this embodiment, the sliding connection mode of the U-shaped plate 46 and the L-shaped plate 47 makes the installation and disassembly process of the collection box 6 simple and fast, without complex operation steps or tools. The staff can quickly complete the cleaning and replacement work of the collection box 6, improving the work efficiency. The anti-slip layer inside the U-shaped plate 46 increases the friction force between the U-shaped plate 46 and the L-shaped plate 47, ensuring that the collection box 6 can be stably installed at the bottom of the workbench 1 during the operation of the equipment and will not fall off easily due to the vibration of the equipment or the impact of the chips, guaranteeing the stability and safety of the equipment operation.

[0050] In summary, compared with the related technology, this equipment ensures the drilling accuracy through the precise positioning of the laser pointer, timely cleaning of the chips by the push plate, and flexible adjustment of the drill bit height by the hydraulic cylinder, and also avoids the influence of chip accumulation.
