Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, and in particular to an automatic drill stringing device and a drill stringing method. Background Technology

[0002] Multi-drilling machines are multi-hole processing machines capable of multi-drill-bit collaborative operation. They are core equipment in production lines for sheet metal products, used for high-precision batch drilling of various sheet metals. Existing multi-drilling machines typically require manual loading. After loading, the sheet metal is placed on the worktable, clamped using a simple clamping device, and then the multi-drill-bit machine directly drives the drilling heads for drilling. After processing, unloading is either done manually or requires a complex unloading mechanism, such as a feeding belt and additional complex pushing or hooking mechanisms, to push or hook the finished sheet metal onto the feeding belt, which then transports it to the collection station.

[0003] However, this existing technology still has the following problems:

[0004] 1. When existing drilling equipment drills holes in strip-shaped and / or plate-shaped slabs, after each slab is processed, the next slab needs to be added manually, and the finished product needs to be removed manually or the above-mentioned complicated unloading mechanism needs to be set up for unloading.

[0005] However, manual loading and unloading requires workers to be constantly on-site to monitor and change boards, resulting in low automation, inability to perform batch and continuous drilling, low processing efficiency, and failure to meet the production and market demands of enterprises. In addition, the complex unloading mechanism described above, with its feeding belt and auxiliary mechanisms, not only results in a large equipment size but also increases the manufacturer's production costs. Moreover, the process of pushing or hooking finished products onto the feeding belt and then transporting them to the collection station by the feeding belt is time-consuming and seriously affects product processing efficiency.

[0006] 2. When drilling slabs, the equipment design is relatively rigid and is only suitable for drilling slabs of a single specification, which is not suitable for widespread application. In addition, it can only clamp and fix the side or two ends of the slab, and the slab will still warp in the longitudinal direction, which will eventually lead to deviation in the drilling of the slab, affect the processing quality, or even cause the slab to be scrapped, thus increasing the production cost of enterprises. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, one of the objectives of the present invention is to provide an automatic drilling device.

[0008] One of the objectives of this invention is achieved by the following technical solution: an automatic drilling device, comprising a frame and a feeding / discharging mechanism, a side-tilting mechanism, a pushing mechanism, a pressing mechanism, and a drilling mechanism mounted on the frame; the frame is provided with a drilling station;

[0009] The feeding and discharging mechanism has a feeding bin and a discharging guide plate. The feeding bin is located above the drilling station, and the discharging guide plate is located below the feeding bin. The receiving end of the discharging guide plate extends toward the discharging side of the drilling station and the side-tilting mechanism.

[0010] The side-tilting mechanism has a load-bearing tilting plate and a side-tilting driver. The load-bearing tilting plate is located at the drilling station. The side-tilting driver is connected to and drives the load-bearing tilting plate to switch between a side-tilting and a horizontal state. When the side-tilting driver drives the load-bearing tilting plate to switch to a horizontal state, the pushing mechanism pushes the batch of slabs to be processed in the feeding bin one by one to the horizontal state of the load-bearing tilting plate according to the drilling process.

[0011] The drilling mechanism has a drilling head and a drilling driver. The drilling driver is connected to and controls the drilling head to drill holes in the blank to be processed on the bearing flip plate which is pressed into a horizontal state by the clamping mechanism. When the blank is drilled, the side flipping driver drives the bearing flip plate to switch to the side flipping state, thereby tilting the finished plate into the discharge guide plate, and the discharge guide plate guides the finished plate to the material pick-up point.

[0012] Furthermore, the feeding hopper has a first feeding hopper and a second feeding hopper. The first feeding hopper and the second feeding hopper each have a front baffle, a rear baffle, and a vertical side plate. The front baffle and the rear baffle are fixedly arranged side by side and spaced apart on the side of the vertical side plate to form a vertical material hopper groove. The groove width of the vertical material hopper groove is adjusted by a crank handle. The first feeding hopper and the second feeding hopper are respectively arranged on both sides above the drilling station so that the vertical material hopper grooves of the first feeding hopper and the second feeding hopper face each other and are used to respectively guide the two ends of the strip-shaped blank to be processed.

[0013] Furthermore, the side of the vertical side plate also has a supporting side plate, which is horizontally arranged below the hopper outlet of the vertical hopper trough of the first and second feeding hoppers. The distance between the surface of the supporting side plate and the hopper outlet of the vertical hopper trough is greater than the thickness of a single slab to be processed and less than the sum of the thicknesses of the two slabs to be processed, so that the slab to be processed located at the bottom of the feeding hopper can fall from the hopper outlet onto the supporting side plate under its own weight, and then slide horizontally on the supporting side plate through the pushing mechanism to push the slab to be processed onto the bearing flap.

[0014] Furthermore, the pushing mechanism has a rack seat, a pushing rack, a balancing gear, a pushing driver, and a pushing rod. The pushing driver and the balancing gear are respectively arranged on different sides of the vertical side plate. The rack seat is arranged above the balancing gear. The pushing rack is fixedly connected to the bottom of the rack seat and meshes with the balancing gear. The pushing rod is arranged on the rack seat and horizontally arranged on the surface of the supporting side plate.

[0015] Limiting slots are provided on the vertical side plate. The output rod of the pusher driver passes through the limiting slot and is fixedly connected to the rack seat. It is used to drive the rack seat along the direction of the limiting slot, thereby controlling the pusher rod to push the blank to be processed onto the bearing flap. After the pusher rod returns to its original position, the next blank to be processed falls into the supporting side plate by its own weight.

[0016] Furthermore, the frame has a horizontally arranged balance bar. One end of the balance bar is connected to the vertical side plate of the first feed bin and the balance gear. The other end of the balance bar movably passes through the vertical side plate of the second feed bin and is connected to the frame, so that the second feed bin slides on the frame along the length direction of the balance bar, which is used to adjust the distance between the second feed bin and the first feed bin and to adapt to the length specification of the current slab to be processed.

[0017] Furthermore, multiple side-tilting actuators are mounted on the frame via side-tilting bases and are equidistantly arranged along the length of the carrying flap, and the multiple side-tilting actuators receive commands to synchronously drive the carrying flap to switch to a tilting or horizontal state;

[0018] The side-tilting driver uses a side-tilting cylinder, which is mounted on the frame via a side-tilting base. The upper end of the side-tilting base is hinged to a swing arm via a pivot, and the swinging part of the swing arm is connected to the bearing flap and the output rod of the side-tilting cylinder.

[0019] When the tilting cylinder controls the swing arm to tilt downward around the pivot, it simultaneously drives the discharge side of the bearing tilting plate to tilt downward, which is used to tilt the slab with the drilled hole to the discharge guide plate.

[0020] When the tilting cylinder controls the swing arm and the bearing tilting plate to tilt upwards and reset to a horizontal state, it is used to carry the slab blank to be drilled.

[0021] Furthermore, the clamping mechanism includes a clamping bracket, a clamping pad, and a clamping cylinder. The clamping bracket is mounted on the frame and positioned horizontally above the drilling station. Multiple clamping cylinders are arranged along the horizontal direction of the clamping bracket. The output rod of each clamping cylinder is vertically downward and connected to the clamping pad, used to control the clamping pad to descend and clamp the blank to be processed.

[0022] Furthermore, the bearing flap has a processing side, and the drilling mechanism is arranged on the processing side of the bearing flap;

[0023] The drilling mechanism also has a feed cylinder, which is mounted on the transverse slide rail of the frame via a transverse slide block. A positioning seat is provided at one end of the transverse slide block near the bearing flap, and the positioning seat is provided with multiple drill slots.

[0024] The drilling driver uses a drilling motor, which is mounted on the longitudinal slide rail of the transverse slide via a longitudinal slide block. The output rod of the feed cylinder is connected to and drives the longitudinal slide block, thereby controlling the drilling head to pass through the drill slot and perform drilling on the blank to be processed.

[0025] Furthermore, the bearing flap has a discharge side, the discharge guide plate and its receiving end are arranged on the discharge side of the bearing flap, the surface of the discharge guide plate is provided with multiple guide slopes of different inclinations from its receiving end to the picking end, and the picking end is integrally bent into a stop block for preventing the finished sheet material from falling.

[0026] Compared with existing technologies, the advantages of the automatic drilling equipment of this invention are as follows:

[0027] (1) The automatic drilling equipment provided in this embodiment realizes the stacking and storage of batches of slabs to be processed by setting up a feeding bin, and realizes automatic and continuous feeding to the drilling station of the machine frame by combining the pusher mechanism with the pusher mechanism.

[0028] In addition, a side-tilting mechanism is provided, which has a load-bearing flap that can serve as a support platform for drilling the slab. The side-tilting mechanism also drives the load-bearing flap through its side-tilting driver, causing the discharge side of the load-bearing flap to tilt downwards, so that the finished slab is tilted downwards and falls into the discharge guide plate. Together with the discharge guide plate, the finished slab is automatically discharged. The entire process does not require continuous manual supervision or individual handling of slabs, and can realize batch and continuous drilling of strip and / or block slabs, which greatly improves the automation level and processing efficiency of the equipment and meets the production and market supply needs of manufacturers.

[0029] Moreover, the automatic drilling equipment of this application only needs to be equipped with a side tilting mechanism and its load-bearing tilting plate. It can work with the feeding bin and the pushing mechanism to support the feeding and drilling of the slab, and can also work with the discharge guide plate to discharge automatically. It replaces the complex mechanism of feeding belt and auxiliary mechanisms such as pushing or hooking for unloading, which greatly reduces the size of the equipment and production cost.

[0030] Moreover, the finished sheet material can be discharged by simply tilting the load-bearing flipper onto the discharge guide plate, without the need for cumbersome processes such as pushing or hooking, or conveying by a feeding belt. The entire discharge process of this invention is very convenient and efficient, greatly improving the efficiency of sheet material processing.

[0031] Meanwhile, the clamping mechanism vertically presses and fixes the slab before drilling, effectively preventing displacement of the slab during drilling and ensuring the accuracy and quality of drilling.

[0032] (2) By setting the feeding hopper as a split first feeding hopper and second feeding hopper, the two ends of the strip slab can be supported respectively, so that the strip slab remains stable during feeding and pushing, and the slab is prevented from tilting or shifting. The guide slope at the upper end of the front baffle and the rear baffle facilitates the smooth feeding of the slab into the hopper, improving the feeding efficiency. The horizontal adjustment hole on the rear baffle, together with the crank handle, realizes the flexible adjustment of the width of the hopper trough, so that the equipment can be adapted to slabs of different widths, expands the applicability of the equipment, and is suitable for widespread application.

[0033] To overcome the shortcomings of the prior art, the second objective of this invention is to provide an automatic drilling method.

[0034] The second objective of this invention is achieved by the following technical solution: an automatic drilling method, which uses the aforementioned automatic drilling equipment to automatically drill holes in a slab, comprising the following steps:

[0035] S1. Feeding from the feeding hopper: Multiple slabs to be processed are fed into the hopper inlet at the top of the feeding hopper, so that the multiple slabs to be processed are stacked vertically in the feeding hopper, and the slabs to be processed at the bottom are exposed at the hopper outlet at the bottom of the feeding hopper.

[0036] S2. Push the material to the drilling station, start the pushing mechanism, and push the blank to be processed at the bottom of the feeding hopper in the horizontal direction towards the drilling station onto the horizontal bearing flap; then, the pushing mechanism retracts and resets, and the next blank to be processed falls into the material outlet position at the bottom of the feeding hopper by its own weight, waiting for the next pushing action.

[0037] S3. Press the blank to be processed, start the pressing mechanism located directly above the drilling station to press and fix the blank to be processed on the bearing flip plate.

[0038] S4. To automatically drill holes in the slab to be processed, start multiple drilling mechanisms arranged on the processing side of the bearing flip plate. The drilling mechanism uses a drilling head to drill holes in the side of the slab to be processed.

[0039] S5. The bearing flap automatically tilts to the side to discharge material. The clamping mechanism releases the clamping state and controls the discharge side of the bearing flap to tilt downwards through the tilting driver, tilting the finished board with drilled holes onto the discharge guide plate. Then, the tilting driver controls the bearing flap to tilt back to the horizontal state, and pushes the next board blank to be processed onto the bearing flap through the pushing mechanism, and so on.

[0040] Compared with existing technologies, the advantages of the automatic drilling method of the present invention are as follows:

[0041] This embodiment provides an automated drilling method that automates the entire process of slab processing—from feeding, pushing, clamping, drilling, and side-tilting discharge—through a cyclical execution of five steps: feeding, pushing, clamping, drilling, and discharge. The entire process eliminates the need for constant human supervision and slab changes, significantly reducing labor intensity and greatly improving the processing efficiency and batch production capacity of strip and / or block slabs. The clamping step ensures the slab's stable fixation during drilling, preventing drilling deviations caused by slab warping or displacement, and guaranteeing processing quality.

[0056] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0057] Example 1

[0058] like Figures 1 to 6 As shown, an automatic drilling machine is used to automatically drill strip-shaped and / or block-shaped slab products of stone, ceramic tile, metal, and wood awaiting drilling processing using a drilling head 601. The automatic drilling machine includes a frame 10 and a feeding / discharging mechanism 20, a side-tilting mechanism 30, a pushing mechanism 40, a clamping mechanism 50, and a drilling mechanism 60 mounted on the frame 10. A drilling station 101 is provided on the frame 10, located in the central area of ​​the frame 10, for receiving the slabs to be processed and providing a working position for drilling.

[0059] The feeding and discharging mechanism 20 has a feeding bin and a discharging guide plate 208. The feeding bin is fixedly installed on the upper part of the frame 10 and located directly above the drilling station 101. The upper end of the feeding bin is the bin inlet, and the lower end is the bin outlet. Multiple blanks to be processed can be vertically stacked and fed into the feeding bin from the upper bin inlet, with the blank at the bottom exposed at the bin outlet. The discharging guide plate 208 is inclined and located below the feeding bin. The receiving end 2081 of the discharging guide plate 208 extends towards the drilling station 101 and the discharging side of the side-tilting mechanism to receive the finished sheet metal after drilling. The finished sheet metal then slides down the discharging guide plate 208 to the picking point, such as the picking end 2082 of the discharging guide plate 208, so that the operator can remove the finished sheet metal.

[0060] The side-tilting mechanism 30 includes a support tilting plate 301 and a side-tilting driver. The support tilting plate 301 is horizontally positioned at the drilling station 101 and is used to support the slab to be processed. The side-tilting driver is mounted on the frame 10, and its output end is connected to the support tilting plate 301. It drives the discharge side of the support tilting plate 301 to tilt downwards, allowing the support tilting plate 301 to switch between a tilted state and a horizontal state. The pushing mechanism 40 is installed on one side of the feeding bin and can move horizontally forward and backward towards the drilling station 101. It is used to push the batch of slabs to be processed in the feeding bin one by one onto the surface of the horizontal support tilting plate 301 according to the drilling process. At this time, the support tilting plate 301 works in conjunction with the feeding bin, the pushing mechanism 40, and serves as a drilling platform for the slabs.

[0061] The drilling mechanism 60 includes a drilling head 601 and a drilling driver. The drilling driver is a servo motor, and the output of the servo motor is connected to the drilling head 601 for control of the drilling head 601 to drill holes in the blank to be processed, which is held in place by the clamping mechanism 50 on the supporting flip plate 301. The clamping mechanism 50 is mounted on the frame 10 and located directly above the drilling station 101. It is used to clamp and fix the blank to be processed onto the supporting flip plate 301 before drilling.

[0062] After the slab drilling is completed, the side-tilting driver drives the bearing tilting plate 301 to tilt downwards, causing the discharge side 3012 of the bearing tilting plate 301 to tilt onto the discharge guide plate 208. The slab slides down the surface of the discharge guide plate 208 to the picking end 2082, completing the automatic discharge. At this time, the bearing tilting plate 301 and the discharge guide plate 208 work together as a coordinating mechanism for discharging the finished slab. This enables automated drilling of slabs made of stone, ceramic tiles, metal, and wood.

[0063] Therefore, the automatic drilling equipment provided in this embodiment realizes the stacking and storage of batches of slabs to be processed by setting up a feeding hopper, and realizes automatic and continuous feeding to the drilling station 101 of the frame 10 by combining the pusher mechanism 40 with the pusher mechanism 40.

[0064] In addition, a side-tilting mechanism 30 is provided, which is equipped with a bearing flap 301 that can serve as a bearing platform for drilling the slab. The side-tilting mechanism 30 also drives the bearing flap 301 through its side-tilting driver, causing the discharge side of the bearing flap 301 to tilt downwards, so that the finished slab is tilted downwards and falls into the discharge guide plate 208. Together with the discharge guide plate, the finished slab is automatically discharged. The entire process does not require continuous manual supervision and individual handling of slabs, and can realize batch and continuous drilling of strip and / or block slabs, which greatly improves the automation level and processing efficiency of the equipment and meets the production and market supply needs of manufacturers.

[0065] Moreover, the automatic drilling equipment of this application only needs to be equipped with a side-tilting mechanism 30 and its bearing flap 301. It can work in conjunction with the feeding bin and the pushing mechanism 40 to support the feeding and drilling of the slab, and can also work in conjunction with the discharge guide plate 208 to discharge automatically. This replaces the complex mechanism of feeding belts and auxiliary mechanisms such as pushing or hooking for unloading, greatly reducing the size of the equipment and production costs.

[0066] Moreover, the finished sheet material can be discharged by simply tilting the load-bearing flip plate 301 onto the discharge guide plate 208, without the need for cumbersome processes such as pushing or hooking materials or conveying by a feeding belt. The entire discharge process of this invention is very convenient and efficient, greatly improving the processing efficiency of the sheet material.

[0067] Meanwhile, the clamping mechanism 50 clamps the slab vertically downwards before drilling, effectively preventing displacement of the slab during drilling and ensuring the accuracy and quality of drilling.

[0068] In this embodiment, the feeding bin is specifically configured as a split structure, including a first feeding bin 201 and a second feeding bin 202. Specifically, as shown... Figures 2 to 3 As shown, the first feed bin 201 and the second feed bin 202 each have a front baffle 203, a rear baffle 204, and a vertical side plate 205. The front baffle 203 and the rear baffle 204 are fixedly arranged side by side and spaced apart from each other on the side of the vertical side plate 205. The front baffle 203, the rear baffle 204, and the vertical side plate 205 together form a vertical material hopper trough 207. The distance between the front baffle 203 and the rear baffle 204 is used to determine the width of the vertical material hopper trough 207, which is used to accommodate the slab to be processed.

[0069] The first feed bin 201 and the second feed bin 202 are respectively located on the upper sides of the drilling station 101, and are arranged side by side along the length of the slab to be processed with a distance between them. The vertical hopper 207 of the first feed bin 201 and the vertical hopper 207 of the second feed bin 202 are arranged facing each other, with the openings of the two vertical hopper hopper 207 facing each other, respectively used to guide the two ends of the strip-shaped slab to be processed. That is, one end of the strip-shaped slab is accommodated in the vertical hopper 207 of the first feed bin 201, and the other end is accommodated in the vertical hopper 207 of the second feed bin 202, thereby realizing the synchronous introduction and positioning of the two ends of the strip-shaped slab.

[0070] Preferably, the upper ends of the front baffle 203 and rear baffle 204 of the first feeding bin 201 and the upper ends of the front baffle 203 and rear baffle 204 of the second feeding bin 202 are respectively provided with outwardly inclined guide slopes. These guide slopes play a guiding role when the slab is fed into the feeding bin, so that the slab can slide smoothly into the vertical hopper 207 and avoid the slab getting stuck or damaged by collision during feeding.

[0071] More preferably, the rear baffle 204 is provided with a horizontal adjustment hole 2041. A crank handle 209 passes through the horizontal adjustment hole 2041, and the rear baffle 204 is locked together with the vertical side plate 205. When a slab with a larger width needs to be fed, the crank handle can be loosened, and the position of the rear baffle 204 relative to the front baffle 203 can be adjusted along the direction of the horizontal adjustment hole 2041, thereby changing the width of the hopper groove between the front baffle 203 and the rear baffle 204 to accommodate slabs of different widths. After adjustment, the crank handle can be tightened again to lock and fix the rear baffle 204.

[0072] Therefore, by setting the feeding bins as separate first feeding bin 201 and second feeding bin 202, the two ends of the strip slab can be supported respectively, keeping the strip slab stable during feeding and pushing, and preventing the slab from tilting or shifting. The guide slopes at the upper ends of the front baffle 203 and the rear baffle 204 facilitate the smooth feeding of the slab into the bins, improving feeding efficiency. The horizontal adjustment hole 2041 on the rear baffle 204, in conjunction with the crank handle 209, enables flexible adjustment of the bin width, allowing the equipment to adapt to slabs of different widths, expanding the applicability of the equipment, and making it suitable for widespread application.

[0073] The vertical side plate 205 in this embodiment also has a supporting side plate 206, which is horizontally disposed below the outlet of the vertical hopper trough 207 of the first feed bin 201 and the second feed bin 202. The distance between the surface of the supporting side plate 206 and the outlet of the vertical hopper trough 207 is greater than the thickness of a single slab to be processed, so that the slab to be processed located at the bottom of the feed bin can fall from the outlet of the hopper onto the supporting side plate 206 under its own weight.

[0074] Specifically, when multiple slabs to be processed are vertically stacked in the feeding hopper, the slab at the bottom layer falls out of the hopper outlet under gravity and is placed horizontally on the surface of the support side plate 206. Since the distance between the support side plate 206 and the hopper outlet is greater than the thickness of a single slab but less than the sum of the thicknesses of two slabs, only one slab can fall from the hopper outlet onto the support side plate 206 at a time. After the slab falls onto the support side plate 206, the pushing mechanism 40 slides along the surface of the support side plate 206, pushing the slab to be processed horizontally onto the bearing flap 301.

[0075] In practical applications, sensors can be installed at the outlet of the vertical hopper 207 to detect whether a slab to be processed has fallen into the support side plate 206. If a slab is detected at the hopper outlet and on the support side plate 206, the corresponding sensor sends a signal to the pushing mechanism 40 to initiate a pushing action. Simultaneously, sensors are installed at the drilling station 101 to detect whether a slab to be processed is present at the drilling station 101. If a slab is present at the drilling station 101, the corresponding sensor sends a signal to the clamping mechanism 50 and the drilling drive to initiate clamping and drilling actions. Thus, through sensor signal feedback, the control system can accurately determine the status of slab feeding and drilling at the drilling station 101, achieving automated control.

[0076] Therefore, by installing support side plates 206 on the vertical side plates, the slabs in the feeding hopper can automatically fall onto the support side plates 206 one by one under their own weight. Combined with the horizontal sliding design of the pushing mechanism 40 on the support side plates 206, automatic slab feeding is achieved without manual intervention. The spacing design between the support side plates 206 and the hopper outlet ensures that only one slab falls out and is exposed at the hopper outlet at a time, avoiding the problems of jamming or overlapping pushes caused by multiple slabs falling out simultaneously. The installation of sensors further improves the automation control level of the equipment, ensuring accurate connection between the feeding and drilling processes.

[0077] The feeding mechanism 40 of this embodiment includes a rack seat 401, a feeding rack 402, a balancing gear 403, a feeding driver, and a feeding rod 405. The feeding driver and the balancing gear 403 are respectively disposed on different sides of the vertical side plate 205. The rack seat 401 is slidably mounted on the side of the vertical side plate 205 via a slide rail slider and is located above the balancing gear 403. The feeding rack 402 is fixedly connected to the bottom of the rack seat 401, and the feeding rack 402 meshes with the balancing gear 403. The feeding rod 405 is fixedly disposed on the rack seat 401 and horizontally arranged above the surface of the supporting side plate 206. The extending direction of the feeding rod 405 is consistent with the feeding direction of the slab.

[0078] A limiting slot 2051 is provided on the vertical side plate 205. The limiting slot 2051 is set horizontally on the vertical side plate 205, and its extension direction is consistent with the pushing direction of the push rod 405. The output rod of the push driver passes through the limiting slot 2051 and is fixedly connected to the rack seat 401. When the push driver is started, its output rod drives the rack seat 401 to move horizontally along the direction of the limiting slot 2051. The rack seat 401 drives the push rack 402 to move synchronously. The push rack 402 maintains the smoothness of movement through meshing transmission with the balance gear 403. At the same time, the rack seat 401 drives the push rod 405 to move horizontally. The push rod 405 pushes the blank to be processed, which has fallen on the support side plate 206, toward the drilling station 101 and onto the bearing flip plate 301.

[0079] After the pusher rod 405 pushes the slab onto the bearing flap 301, the pusher driver reverses the direction, and the pusher rod 405 retracts to its initial position. During the retraction process, the bottom of the pusher rod 405 slides on the surface of the support side plate 206. After the pusher rod 405 retracts to its original position, especially after it returns to the rear of the hopper outlet, the next slab to be processed falls from the hopper outlet onto the support side plate 206 under its own weight, awaiting the next pusher action.

[0080] Therefore, the rack and pinion seat 401 is equipped with a pusher rack 402 at the bottom and a pusher rod 405 at the top. Through the meshing transmission between the pusher rack 402 and the balance gear 403, the pusher rod 405 runs smoothly and is accurately positioned during the pushing process, ensuring that the slab can be accurately pushed to the predetermined position of the supporting flip plate 301. The limiting strip hole 2051 guides and limits the output rod of the pusher driver, ensuring the accuracy of the pushing direction. After the pusher rod 405 returns to its original position, the next slab automatically falls into the support side plate 206, realizing continuous automatic feeding and pushing, further improving the automation level and processing efficiency of the equipment.

[0081] In this embodiment, the frame 10 also has a horizontally arranged balance bar 102. One end of the balance bar 102 is connected to the vertical side plate 205 of the first feed bin 201 and the balance gear 403. The other end of the balance bar 102 movably passes through the vertical side plate 205 of the second feed bin 202 and is connected to the frame 10, so that the second feed bin 202 can slide on the frame 10 along the length direction of the balance bar 102.

[0082] Specifically, the vertical side plate 205 of the second feed bin 202 is mounted on the slide rail of the frame 10 via a sliding block, and is slidably fitted with the balance bar 102 via a bearing sleeve, allowing the second feed bin 202 to slide freely along the direction of the balance bar 102. By adjusting the sliding position of the second feed bin 202 relative to the first feed bin 201 along the direction of the balance bar 102, the distance between the first feed bin 201 and the second feed bin 202 can be changed, thereby adapting to the length specification of the slab to be processed. The balance gear 403 is also fitted with the balance bar 102 via a bearing sleeve, allowing the balance gear 403 to rotate freely on the balance bar 102, and also providing a support point for the meshing assembly of the rack seat 401 and the push rack 402.

[0083] In actual use, the first feed bin 201 and the second feed bin 202 are arranged side by side on the frame 10 along the length of the strip blank and are spaced apart from each other. The balance bar 102 is parallel to the strip blank in the processing state.

[0084] The sliding of the second feeding bin 202 provided in this embodiment can be achieved in two ways: First, the worker manually pushes the second feeding bin 202 to slide along the balance bar 102, and after adjustment, it is fixed by a locking mechanism; second, a driver is used to automatically drive and control the sliding of the second feeding bin 202. Specifically, a touch control screen can be installed on the frame 10. The operator inputs the size parameters of the slab to be processed through the touch control screen, and the control system automatically controls the driver to act according to the input size. At this time, the balance bar 102 is replaced by a threaded rod, and the vertical side plate 205 of the second feeding bin 202 is installed on the threaded rod through a threaded slide. The threaded rod is driven to rotate so that the second feeding bin 202 moves relative to the first feeding bin 201 to a predetermined distance.

[0085] Therefore, by setting a balance bar 102 on the frame 10, and connecting the balance bar 102 to the first feed bin 201 and the second feed bin 202, the second feed bin 202 can be adjusted by sliding along the direction of the balance bar 102, thereby enabling the drilling equipment of this embodiment to adapt to slabs of different lengths and specifications, significantly expanding the applicability and versatility of the equipment. The touch control screen, in conjunction with the automatic control mode of the driver, realizes the automatic adjustment of the feed bin spacing, further improving the intelligence level and ease of operation of the equipment.

[0086] like Figures 4 to 5As shown, the tilting actuator in this embodiment uses a tilting cylinder 302, which is vertically mounted on the frame 10 via a tilting base 303. The tilting base 303 is generally designed as an L-shaped structure, with its lower end fixedly mounted to the frame 10 and its upper end configured as two separate support arms. A swing arm 304 is hinged to the upper end of the tilting base 303 via a pivot, and the swing arm 304 is hinged to the gap between the two support arms via a pivot, so that the swing arm 304 can freely tilt and swing within the gap.

[0087] Multiple side-tilting actuators are mounted on the frame 10 via side-tilting bases 303 and are equidistantly arranged along the length of the carrying flap 301. Moreover, the multiple side-tilting actuators receive unified instructions sent by the control system to control the multiple side-tilting actuators to control the carrying flap 301 to switch to tilting or horizontal state at a unified rhythm, thereby accurately controlling the side-tilting and horizontal movement of the carrying flap 301.

[0088] The swing arm 304 has its swinging part connected to the load-bearing flap 301 and the output rod of the side-tilting cylinder 302. For example, the top of the swing arm 304 is connected to the load-bearing flap 301, and the bottom is connected to the output rod of the side-tilting cylinder 302. When the side-tilting cylinder 302 is activated, its output rod extends or retracts vertically, driving the swing arm 304 to swing up and down around the pivot. The swing arm 304 drives the load-bearing flap 301 to move synchronously.

[0089] Specifically, after the slab drilling is completed, the side-tilting cylinder 302 controls the swing arm 304 to tilt downwards around the pivot. Simultaneously, the swing arm 304 drives the discharge side 3012 of the bearing flap 301 to tilt downwards, changing the bearing flap 301 from a horizontal to an inclined state, thus tilting the finished slab onto the discharge guide plate 208. After the finished slab is tilted, the side-tilting cylinder 302 reverses its action, controlling the swing arm 304 and the bearing flap 301 to tilt upwards back to a horizontal state. The bearing flap 301 returns to a horizontal position to support the next slab to be drilled.

[0090] Therefore, the side-tilting cylinder 302 drives the swing arm 304 to tilt the bearing flap 301 to the side. This design is simple in structure, reliable in operation, and provides fast and stable tilting. The L-shaped side-tilting base 303, in conjunction with the swing arm 304 hinged in the gap between the support arms, ensures the stability of the tilting trajectory of the swing arm 304, guaranteeing the accuracy of the tilting and resetting actions of the bearing flap 301, and enabling the automatic tilting and unloading of the finished sheet material after drilling.

[0091] like Figure 1As shown, the clamping mechanism 50 of this embodiment includes a clamping bracket 501, a clamping pad 502, and a clamping cylinder 503. The clamping bracket 501 is fixedly mounted on the frame 10 and is horizontally positioned directly above the drilling station 101. Multiple clamping cylinders 503 are arranged along the horizontal direction of the clamping bracket 501, that is, multiple clamping cylinders 503 are spaced apart along the length of the clamping bracket 501. The output rod of each clamping cylinder 503 extends vertically downwards, and its end is connected to the clamping pad 502.

[0092] When the slab to be processed is pushed onto the bearing flap 301 by the pushing mechanism 40 and reaches the predetermined position, the clamping cylinder 503 is activated, and its output rod extends downward, driving the clamping pad 502 to descend. The clamping pad 502 presses against the upper surface of the slab to be processed, pressing and fixing the slab onto the bearing flap 301. The clamping pad 502 is made of a material with a certain elasticity and coefficient of friction, which can provide sufficient clamping force to prevent the slab from moving while avoiding damage to the slab surface.

[0093] After drilling is completed, the clamping cylinder 503 reverses its action, and its output rod retracts upward, driving the clamping pad 502 to rise, releasing the clamping state on the finished board so that the flip plate 301 can be flipped to the side for material discharge.

[0094] Therefore, by horizontally installing a clamping bracket 501 directly above the drilling station 101 and arranging multiple clamping cylinders 503 along the bracket direction, multi-point clamping of the slab is achieved, ensuring that the slab is subjected to uniform force and is firmly fixed during the drilling process. This effectively prevents the slab from warping or shifting during the drilling process, ensuring the accuracy and quality of the drilling process, and avoiding drilling deviations and slab scrap caused by slab movement.

[0095] like Figure 1 , 4 As shown in Figure 6, the bearing flap 301 of this embodiment has a processing side 3011. The drilling mechanism 60 is arranged on the processing side 3011 of the bearing flap 301. The drilling mechanism 60 also has a feed cylinder 605, which is mounted on the transverse slide rail 103 of the frame 10 via a transverse slide block 606. The transverse slide block 606 can slide horizontally on the frame 10 along the transverse slide rail 103. A positioning seat 6061 is provided at one end of the transverse slide block 606 near the bearing flap 301. The positioning seat 6061 is vertically arranged and has multiple drill slots 6062 at its upper end. The positions of the drill slots 6062 correspond to the positions on the blank to be drilled.

[0096] In this embodiment, the drilling driver uses a drilling motor 602, which is mounted on the longitudinal slide rail 604 of the transverse slide 606 via a longitudinal slide 603. The longitudinal slide 603 can slide longitudinally along the longitudinal slide rail 604 on the transverse slide 606. The output rod of the feed cylinder 605 is connected to the longitudinal slide 603 and is used to drive the longitudinal slide 603 to move along the longitudinal slide rail 604. The drilling bits 601 are mounted on the output shaft of the drilling motor 602. The position of the drilling bits 601 corresponds to the drill slot 6062 on the positioning seat 6061, so that multiple drilling bits 601 can pass through the drill slot 6062 on the positioning seat 6061 one by one and perform drilling on the side of the slab.

[0097] When drilling is required, the drilling motor 602 starts, driving the drilling head 601 to rotate. The feed cylinder 605 starts, and its output rod drives the longitudinal slide 603 to move along the longitudinal slide rail 604 toward the bearing flap 301. The longitudinal slide 603 drives the drilling motor 602 and the drilling head 601 to move synchronously. The drilling head 601 passes through the drill slot 6062 on the positioning seat 6061 and contacts the side of the blank to be processed, performing drilling on the blank. After drilling is completed, the feed cylinder 605 reverses and drives the longitudinal slide 603 to retract, and the drilling head 601 exits the finished sheet.

[0098] Preferably, the drilling motor 602 can also be mounted on a longitudinal slide block 603 via a vertically arranged slide rod and slide block, with an operating handwheel at the upper end of the slide rod. By manually operating the handwheel to control the rotation of the slide rod, the drilling motor 602 can be driven to rise and fall along the vertical slide block, thereby adjusting the vertical height of the drilling head 601 to adapt to the drilling needs of slabs with different thicknesses. The vertical slide rod and operating handwheel make the vertical height of the drilling head 601 adjustable, further expanding the equipment's adaptability to slabs of different thicknesses.

[0099] Therefore, by setting up a double-layer sliding structure of transverse slide 606 and longitudinal slide 603, precise feed control of the drill bit 601 in both transverse and longitudinal directions is achieved, ensuring the accuracy of the drilling position. The servo motor, as the drill bit driver, has advantages such as high control precision, fast response speed, and digital programmability, enabling one-key switching and precise control of various drilling position parameters. The drill slot 6062 on the positioning seat 6061 guides and limits the drill bit 601, preventing it from deviating during drilling.

[0100] In this embodiment, the supporting flap 301 has a discharge side 3012, and the discharge guide plate 208 and its receiving end 2081 are arranged on the discharge side 3012 of the supporting flap 301. The surface of the discharge guide plate 208 is provided with multiple guide slopes 2084 with different inclinations from its receiving end 2081 to its picking end 2082. Specifically, the surface of the discharge guide plate 208 is sequentially set with multiple slope segments with gradually changing or segmented inclination angles from the receiving end 2081 to the picking end 2082, so that the slab can smoothly transition when sliding on the discharge guide plate 208, and avoid the slab from bouncing or shifting due to sudden angle changes.

[0101] Additionally, a baffle block 2083 is integrally bent and formed at the material-receiving end 2082 of the discharge guide plate 208. The baffle block 2083 is integrally bent upwards at the material-receiving end 2082 to prevent the finished board from slipping and falling out of the material-receiving end 2082. When the finished board slides down the surface of the discharge guide plate 208 to the material-receiving end 2082, the baffle block 2083 blocks the finished board at the material-receiving end 2082, making it easy for operators to remove the finished board and preventing it from falling to the ground and causing damage.

[0102] Therefore, by setting multiple guide slopes 2084 with different inclinations on the discharge guide plate 208, the finished sheet material is able to slide smoothly and steadily, avoiding impact damage caused by excessive sliding speed or sudden angle changes. The baffle block 2083, integrally bent at the picking end 2082, has a simple structure and is easy to form, effectively preventing the finished sheet material from falling from the picking end 2082, thus improving the safety and reliability of the equipment.

[0103] Example 2

[0104] like Figure 7 As shown, an automatic drilling method, which uses the aforementioned automatic drilling equipment to automatically drill holes in a slab, includes the following steps:

[0105] Step S1: Feeding the hopper. Multiple slabs to be processed are fed into the hopper through the upper inlet, so that they are vertically stacked within the hopper, with the bottom slab exposed at the lower outlet. In practice, workers can manually feed the slabs into the hopper, or an automatic feeding device, such as a vibrating hopper or conveyor belt, can be used.

[0106] More specifically, before feeding, after the equipment is started, the operator first adjusts the equipment according to the specifications and dimensions of the slab to be processed. By inputting the length and width parameters of the slab through the touch control screen, the control system automatically drives the second feeding bin 202 to slide along the balance bar 102 to a suitable distance between it and the first feeding bin 201; at the same time, according to the width of the slab, the operator can loosen the crank handle and adjust the position of the rear baffle 204 along the horizontal adjustment hole 2041 so that the width of the hopper between the front baffle 203 and the rear baffle 204 matches the width of the slab; according to the thickness of the slab, the operator can adjust the vertical height of the drill bit 601 by operating the handwheel.

[0107] After the equipment is adjusted, the operator or the operator can put multiple slabs to be processed into the hopper inlets at the top of the first feed hopper 201 and the second feed hopper 202 respectively. The two ends of the slabs are respectively placed in the vertical hopper slots 207 of the two feed hoppers and are stacked vertically.

[0108] Step S2: Pushing material to drilling station 101. The pushing mechanism 40 is activated, and the output rod of the pushing cylinder 404 drives the rack seat 401 to move horizontally along the direction of the limiting slot 2051. The rack seat 401 drives the pushing rod 405 to move synchronously. The pushing rod 405 pushes the blank to be processed located at the bottom of the feeding bin towards the drilling station 101 onto the bearing flap 301 in a horizontal direction. Then, the pushing mechanism 40 reverses its action, and the pushing rod 405 retracts and resets, sliding back to its initial position on the surface of the support side plate 206. The next blank to be processed falls from the feed bin outlet onto the support side plate 206 under its own weight, waiting for the next pushing action.

[0109] Step S3: Press the blank to be processed. Activate the pressing mechanism 50 positioned directly above the drilling station 101. The output rod of the pressing cylinder 503 extends downwards, driving the pressing pad 502 to descend, pressing and fixing the blank to be processed onto the supporting flap 301. The pressing force can be controlled by adjusting the air pressure of the pressing cylinder 503.

[0110] Step S4: Automatic drilling of the slab to be processed. Multiple drilling mechanisms 60, positioned on the processing side 3011 of the supporting flip plate 301, are activated. The drilling motor 602 drives the drilling head 601 to rotate, and the feed cylinder 605 drives the longitudinal slide 603 to move along the longitudinal slide rail 604 towards the supporting flip plate 301. The drilling head 601 passes through the drill exit slot 6062 on the positioning seat 6061 and drills the side of the slab to be processed. After drilling is completed, the feed cylinder 605 drives the longitudinal slide 603 to retract, and the drilling head 601 exits the finished slab. The drilling driver uses a servo motor, and the drilling depth and position can be precisely controlled by the servo control system. When the lateral position needs to be adjusted, it can slide and adjust along the lateral slide rail 103 of the frame 10.

[0111] Step S5: The bearing tilting plate 301 automatically tilts to the side to discharge the material. The clamping mechanism 50 rises to release the finished sheet metal, releasing the clamping state. The tilting cylinder 302 is activated, driving the swing arm 304 to tilt downwards around the pivot. The swing arm 304 drives the discharge side 3012 of the bearing tilting plate 301 to tilt downwards, pouring the finished sheet metal with drilled holes onto the discharge guide plate 208. The finished sheet metal slides down the guide slope 2084 of the discharge guide plate 208 to the picking end 2082, where it is blocked by the stop block 2083 for the operator to remove. Then, the tilting cylinder 302 reverses its action, controlling the swing arm 304 and the bearing tilting plate 301 to tilt upwards and reset to a horizontal state. At this point, the drilling of one sheet metal blank is completed. Then, returning to step S2, the next blank to be processed is pushed onto the bearing flip plate 301 by the pushing mechanism 40, and so on, to realize continuous automatic drilling processing of batch blanks.

[0112] Therefore, this embodiment provides an automated drilling method that automates the entire process of slab processing—from feeding, pushing, clamping, drilling, and side-tilting discharge—through the cyclical execution of five steps: feeding, pushing, clamping, drilling, and discharge. The entire process eliminates the need for constant human supervision and slab replacement, significantly reducing labor intensity and greatly improving the processing efficiency and batch production capacity of strip and / or block slabs. The clamping step ensures the slab's stable fixation during drilling, preventing drilling deviations caused by slab warping or displacement, and guaranteeing processing quality.

[0113] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
