Description

Technical Field

[0001] This invention relates to the field of parts processing technology, and in particular to a drilling device and method for processing valve components. Background Technology

[0002] After the valve pipe is cast, a flange structure is usually machined at its end to achieve a reliable connection with other piping systems. This flange structure can be a flange blank reserved during the casting stage or a flange plate integrally formed at the pipe end through subsequent machining. Regardless of the form, bolt holes need to be precisely drilled on the flange circumference according to the standard-specified number, diameter, and distribution angle to ensure a reliable and airtight connection when fastened to the mating flange with bolts.

[0003] In many small and medium-sized manufacturing enterprises or traditional production lines, the drilling of valve pipe flanges still relies mainly on manual operation. Specifically, operators need to manually move and clamp the casting onto the drilling machine's worktable, determine the first hole position with the help of scribing lines, templates, or simple positioning fixtures, and then start the drilling machine to complete the drilling of a single hole. After drilling one hole, the clamps must be manually released, the workpiece rotated to the next hole position (usually with the assistance of visual inspection, a protractor, or an indexing plate), repositioned and clamped, and then the next hole is machined. The entire process is highly repetitive, labor-intensive, and only one hole can be machined at a time.

[0004] This traditional method of manual loading and unloading combined with single-hole drilling has obvious drawbacks: on the one hand, frequent manual intervention not only reduces the overall processing efficiency, but also easily leads to hole position deviation due to positioning errors, affecting the interchangeability and sealing performance of the flange; on the other hand, in mass production scenarios, this method is difficult to meet the cycle time requirements, becoming a bottleneck restricting the improvement of production capacity. Summary of the Invention

[0005] The purpose of this invention is to provide a drilling device and method for processing valve parts, which integrates functions such as automatic conveying, intelligent clamping, multi-head adjustable drilling and automatic waste collection, and realizes automated drilling operation with high efficiency, high precision and low manual intervention.

[0006] To achieve the above objectives, in a first aspect, the present invention provides a drilling device for processing valve components, comprising a base, a conveying assembly, a clamping and positioning assembly, a drilling assembly, and a collecting assembly. The conveying assembly includes a support plate and a conveyor belt, the conveyor belt being rotatably mounted on the base, and the support plate being disposed on both sides of the conveyor belt. The clamping and positioning assembly includes two clamping plates, a first screw, and a first motor. The two clamping plates are slidably mounted on one side of the conveyor belt. The first screw has two opposite threads and is threadedly connected to the two clamping plates. The output end of the first motor is connected to the first... The drilling assembly includes a screw connection; it comprises a lifting cylinder, a second motor, a lifting plate, multiple mounting seats, an adjuster, multiple drill bits, and a brush. The lifting plate is positioned above the clamping plate. The output end of the lifting cylinder is connected to the second motor, and the output end of the second motor is connected to the lifting plate. The multiple mounting seats are slidably arranged around the lifting plate. The adjuster is used to adjust the position of the multiple mounting seats. The multiple drill bits are respectively mounted on the multiple mounting seats. The brush is mounted on the lifting plate. The collection assembly is mounted on the base and is used to collect the waste chips generated during drilling.

[0007] The conveying assembly also includes a guide plate, which is disposed on the support plate and is used to correct the position of valve components.

[0008] The guide plate includes two guide plate bodies, two adjusting blocks, an adjusting screw, and an adjusting motor. The two guide plate bodies are rotatably connected to the support plate and are located on both sides of the conveyor belt. The two adjusting blocks are slidably disposed on the support plate and inserted into the grooves on the guide plate bodies. The adjusting screw has two opposite threads and is threadedly connected to the two adjusting blocks. The output end of the adjusting motor is connected to the adjusting screw.

[0009] The mounting base includes a base body, a locking block, and a locking screw. The base body is slidably mounted on the lifting plate, the locking block is slidably mounted on one side of the base body and close to the lifting plate, and the locking screw is threadedly connected to the locking block and rotatably connected to the base body.

[0010] The adjuster includes multiple connecting rods, a pressure plate, a clamping screw, and a clamping motor. The pressure plate is slidably mounted on the lifting plate. One end of each of the multiple connecting rods is rotatably connected to the pressure plate, and the other end of each of the multiple connecting rods is respectively connected to multiple bases. The output end of the clamping motor is connected to the clamping screw.

[0011] The brush includes a support rod, an elastic element, and a brush body. The support rod is fixed on the lifting plate, the brush body is slidably disposed on the support rod, and the elastic element is disposed between the support rod and the brush body.

[0012] The collection assembly includes a collection platform, a rotating rod, a third motor, and a collection box. The rotating rod is rotatably mounted on one side of the base, and the collection platform is fixed to the top of the rotating rod for collecting waste generated during drilling. The third motor drives the rotating rod to rotate, and the collection box is fixed to the base for collecting the waste discharged from the collection platform.

[0013] The collection platform includes a platform body, a sealing plate, and a counterweight. The platform body is fixed to the rotating rod, the sealing plate is rotatably connected to the platform body and located on one side of the platform body, and the counterweight is fixed to the sealing plate.

[0014] The collection platform also includes a sealing strip, which is fixed to the side of the platform body near the sealing plate.

[0015] Secondly, the present invention also provides a drilling method for processing valve components, comprising: Valve components are placed on a conveyor belt for transport; After the valve components are moved to the designated position, the first motor is started to drive the two clamping plates to position the valve components. The lifting cylinder is activated to move the drill bit down to drill holes, and the drilling position is adjusted by the second motor to drill multiple holes. The brush cleans the surface of the valve components during rotation. The collection component collects the waste generated during drilling.

[0016] This invention discloses a drilling device and method for processing valve components. The base, made of high-strength metal material, serves as the supporting foundation for the entire device, ensuring stability and vibration resistance during operation. The conveying assembly, comprising a support plate and a conveyor belt, enables automatic feeding and transport of valve components. The conveyor belt, rotatably mounted on the base via a transmission mechanism, continuously and smoothly transports the parts to be processed. The support plates, symmetrically arranged on both sides of the conveyor belt, guide and limit movement, preventing parts from shifting or tipping during transport, thus ensuring the smooth progress of subsequent processes.

[0017] Two clamping plates are slidably disposed along one side of the conveyor belt and are threadedly connected to the first screw. The first screw has two sections of threaded structure with opposite directions of rotation (i.e., left-hand and right-hand threads). When the first motor drives the first screw to rotate, the two clamping plates can move synchronously towards or away from each other, thereby achieving adaptive clamping and loosening of parts of different sizes, improving the compatibility and automation of the equipment.

[0018] The lifting cylinder is fixed to the frame, and its output end is connected to a second motor. The output shaft of the second motor is connected to the lifting plate, which drives the lifting plate to move up and down, thereby controlling the feed and retraction of the drill bit. Multiple mounting seats are evenly arranged along the circumference of the lifting plate, and each mounting seat is equipped with a drill bit. Different diameters or types of drill bits can be configured according to actual processing requirements. The adjuster is linked to each mounting seat and is used to adjust the relative position between each drill bit to adapt to different hole spacing, number of holes, and hole shape processing requirements, significantly improving the flexibility and applicability of the equipment. In addition, a brushing mechanism is integrated on the lifting plate, which can automatically clean metal debris from the surface of the part and the surrounding area after each drilling, preventing residue from affecting the next positioning or causing wear to the equipment.

[0019] The collection component is located below the base or near the drilling area to collect metal shavings generated during drilling. This component typically includes a shavings collection trough, a shavings guide channel, and a suction or vibration auxiliary device. It efficiently recovers waste, keeps the work area clean, and facilitates subsequent waste disposal and resource recycling, aligning with green manufacturing principles.

[0020] The drilling device for valve component processing provided by this invention integrates functions such as automatic conveying, intelligent clamping, multi-head adjustable drilling, and automatic waste collection, achieving high-efficiency, high-precision, and low-manual-intervention automated drilling operations. It is particularly suitable for batch drilling of small and medium-sized parts in the valve manufacturing industry. Attached Figure Description

[0033] First Embodiment Please see Figures 1-7 This invention provides a drilling device for processing valve parts, including a base 101, a conveying assembly 102, a clamping and positioning assembly 103, a drilling assembly 104, and a collecting assembly 105. The conveying assembly 102 includes a support plate 106 and a conveyor belt 107. The conveyor belt 107 is rotatably mounted on the base 101, and the support plate 106 is disposed on both sides of the conveyor belt 107. The clamping and positioning assembly 103 includes two clamping plates 108, a first screw 109, and a first motor 110. The two clamping plates 108 are slidably disposed on one side of the conveyor belt. The first screw 109 has two opposite threads and is threadedly connected to the two clamping plates 108. The output end of the first motor 110 is connected to the first screw 109. The drilling... Component 104 includes a lifting cylinder 111, a second motor 112, a lifting plate 113, multiple mounting seats 114, an adjuster 115, multiple drill bits 116, and a brush 117. The lifting plate 113 is disposed above the clamping plate 108. The output end of the lifting cylinder 111 is connected to the second motor 112, and the output end of the second motor 112 is connected to the lifting plate 113. The multiple mounting seats 114 are slidably disposed around the lifting plate 113. The adjuster 115 is used to adjust the position of the multiple mounting seats 114. The multiple drill bits 116 are respectively disposed on the multiple mounting seats 114. The brush 117 is disposed on the lifting plate 113. The collecting component 105 is disposed on the base 101 and is used to collect the waste chips generated during drilling.

[0034] In this embodiment, the present invention provides a high-efficiency, precise and automated drilling device for processing valve parts, which aims to solve the problems of low drilling efficiency, inaccurate positioning, difficulty in cleaning up waste chips and difficulty in adapting to the processing of multi-specification parts in the prior art.

[0035] The base 101, serving as the supporting foundation for the entire device, is made of high-strength metal material to ensure stability and vibration resistance during equipment operation. The conveying assembly 102, used for automatic feeding and transfer of valve components, includes a support plate 106 and a conveyor belt 107. The conveyor belt 107 is rotatably mounted on the base 101 via a transmission mechanism, enabling continuous and stable transport of the parts to be processed. The support plates 106 are symmetrically arranged on both sides of the conveyor belt 107, serving as guides and limiters to prevent parts from shifting or tipping during transport, thus ensuring the smooth progress of subsequent processes.

[0036] Two clamping plates 108 are slidably disposed along one side of the conveyor belt and are threadedly connected to the first screw 109 respectively. The first screw 109 has two sections of threaded structure with opposite directions of rotation (i.e., left-hand and right-hand threads). When the first motor 110 drives the first screw 109 to rotate, the two clamping plates 108 can move synchronously towards or away from each other, thereby realizing adaptive clamping and loosening of parts of different sizes, improving the compatibility and automation level of the equipment.

[0037] The lifting cylinder 111 is fixed to the frame, and its output end is connected to the second motor 112. The output shaft of the second motor 112 is connected to the lifting plate 113, which drives the lifting plate 113 to move up and down, thereby controlling the feed and retraction of the drill bit 116. Multiple mounting seats 114 are evenly arranged along the circumference of the lifting plate 113, and each mounting seat 114 is equipped with a drill bit 116. Different diameters or types of drill bits 116 can be configured according to actual processing requirements. The adjuster 115 is linked with each mounting seat 114 to adjust the relative position between each drill bit 116 to adapt to different hole spacing, number of holes, and hole shape processing requirements, significantly improving the flexibility and applicability of the equipment. In addition, a sweeping brush 117 mechanism is integrated on the lifting plate 113, which can automatically clean the metal debris on the surface and surrounding area of ​​the part after each drilling, avoiding residue from affecting the next positioning or causing wear on the equipment.

[0038] The collection component 105 is located below the base 101 or near the drilling area to collect metal shavings generated during drilling. This component typically includes a shavings collection trough, a shavings guide channel, and a suction or vibration auxiliary device. It efficiently recycles waste, keeps the work area clean, and facilitates subsequent waste disposal and resource recycling, aligning with the concept of green manufacturing.

[0039] The drilling device for valve component processing provided by this invention integrates functions such as automatic conveying, intelligent clamping, multi-head adjustable drilling, and automatic waste collection, achieving high-efficiency, high-precision, and low-manual-intervention automated drilling operations. It is particularly suitable for batch drilling of small and medium-sized parts in the valve manufacturing industry.

[0040] The conveying assembly 102 also includes a guide plate, which is disposed on the support plate 106 and is used to correct the position of the valve components.

[0041] The guide plate is mounted on the support plate 106 and located on both sides of the conveyor belt 107, extending along the conveying direction. This guide plate is not a fixed structure, but rather has adjustability and self-adaptive capabilities, allowing for flexible adjustment of its inner spacing according to the external dimensions of valve components of different specifications, thus achieving universal guidance and precise alignment for various types of parts.

[0042] The guide plate includes two guide plate bodies 118, two adjusting blocks 119, an adjusting screw 120, and an adjusting motor 121. The two guide plate bodies 118 are rotatably connected to the support plate 106 and are located on both sides of the conveyor belt 107. The two adjusting blocks are slidably disposed on the support plate 106 and inserted into the grooves on the guide plate bodies 118. The adjusting screw 120 has two opposite threads and is threadedly connected to the two adjusting blocks 119. The output end of the adjusting motor 121 is connected to the adjusting screw 120.

[0043] The two guide plate bodies 118 are rotatably connected to the corresponding support plate 106 through hinge shafts or rotating pairs, so that they can swing within a certain angle range to adapt to the slight displacement of the parts during the conveying process and apply a gentle guiding force to avoid damage or jamming of the parts caused by rigid collisions.

[0044] Each guide plate body 118 has a groove structure on its back or bottom, and two adjusting blocks 119 are slidably mounted on the support plate 106 and inserted into the grooves of the corresponding guide plate bodies 118. When the adjusting blocks 119 move laterally along the support plate 106, they push or pull the grooves, thereby causing the guide plate bodies 118 to rotate around their rotation connection points, changing the opening width between the inner sides of the two guide plate bodies 118.

[0045] The adjusting screw 120 passes between the two adjusting blocks 119 and has two sections of threads with opposite directions of rotation (i.e., one end is a left-hand thread and the other end is a right-hand thread). This double-ended reverse thread design allows the two adjusting blocks 119 to move synchronously towards or away from each other when the adjusting screw 120 rotates, thereby achieving linkage control of the opening and closing actions of the guide plate bodies 118 on both sides. The output end of the adjusting motor 121 is connected to one end of the adjusting screw 120 via a coupling or gear pair. The control system automatically drives the adjusting motor 121 to operate according to preset component parameters, thereby precisely adjusting the distance between the guide plates.

[0046] The mounting base 114 includes a base body 122, a locking block 123, and a locking screw 124. The base body 122 is slidably disposed on the lifting plate 113. The locking block 123 is slidably disposed on one side of the base body 122 and close to the lifting plate 113. The locking screw 124 is threadedly connected to the locking block 123 and rotatably connected to the base body 122.

[0047] The base 122 is generally shaped like a slider, and its bottom is provided with a sliding structure (such as a dovetail groove, T-slot, or linear slide rail) that matches the guide rail or slide groove on the lifting plate 113. This allows it to slide smoothly along the radial direction of the lifting plate 113, enabling the drill bit 116 to be adjusted in the horizontal plane. This sliding arrangement allows multiple mounting seats 114 to be flexibly arranged according to the hole distribution requirements of different valve components, significantly improving the equipment's adaptability to complex processing tasks such as multi-hole and asymmetrical hole positions.

[0048] On the side of the base 122 near the lifting plate 113, there is a locking block 123. This locking block 123 can be slidably embedded in a guide groove inside or on the side of the base 122 along a direction perpendicular to the sliding direction (usually vertical), and is located between the base 122 and the lifting plate 113. When it is necessary to fix the position of the mounting base 114, tightening the locking screw 124 pushes the locking block 123 downwards to press against the surface of the lifting plate 113. Friction is used to achieve a rigid lock between the base 122 and the lifting plate 113, preventing the mounting base 114 from shifting due to vibration or cutting force during drilling, thereby ensuring drilling accuracy and processing stability.

[0049] The locking screw 124 and the locking block 123 are connected by a thread, and its upper end or middle is rotatably connected to the base 122 through a bearing, bushing, or other structure. This design ensures that when the locking screw 124 is rotated, the screw itself does not move the base 122, but only drives the locking block 123 to move linearly, making operation simple and the locking effect reliable. In addition, this structure facilitates quick loosening and repositioning, improving the efficiency of model changeover and debugging.

[0050] The adjuster 115 includes multiple connecting rods 125, a pressure plate 126, a clamping screw 127, and a clamping motor 128. The pressure plate 126 is slidably disposed on the lifting plate 113. One end of each of the multiple connecting rods 125 is rotatably connected to the pressure plate 126, and the other end of each of the multiple connecting rods 125 is respectively connected to multiple seats 122. The output end of the clamping motor 128 is connected to the clamping screw 127.

[0051] The pressure plate 126 has an annular or disc-shaped structure and is coaxially slidably disposed above or below (preferably above) the lifting plate 113. Multiple hinge points are evenly distributed around its outer circumference. One end of each of the multiple connecting rods 125 is rotatably connected to a corresponding hinge point on the pressure plate 126 (e.g., via a pin or ball joint), and the other end is rotatably connected to the seat body 122 (or its extension arm) of each mounting base 114, forming a multi-link linkage mechanism.

[0052] When the clamping motor 128 starts and drives the clamping screw 127 to rotate, the rotational motion of the clamping screw 127 is converted into linear motion of the pressure plate 126 along the axial direction (i.e., perpendicular to the plane of the lifting plate 113) due to the nut pair or lead screw pair structure between the clamping screw 127 and the lifting plate 113 or the frame. When the pressure plate 126 moves downward, the thrust is transmitted to the corresponding mounting base 114 through the connecting rods 125, forcing it to move synchronously towards the center along the slide on the lifting plate 113; conversely, when the pressure plate 126 moves upward, it drives the mounting base 114 to unfold outward. Because the clamping screw 127 has a precise pitch, in conjunction with servo or stepper motor control, high-precision stepless adjustment of the radial position of the mounting base 114 can be achieved.

[0053] The brush 117 includes a support rod 129, an elastic element 130, and a brush body 131. The support rod 129 is fixed on the lifting plate 113, the brush body 131 is slidably disposed on the support rod 129, and the elastic element 130 is disposed between the support rod 129 and the brush body 131.

[0054] The support rod 129 is a rigid structural component, typically made of stainless steel or a high-strength alloy. One end is securely fixed to the lower surface or side edge of the lifting plate 113 (preferably near the working area of ​​the drill bit 116) to provide a stable mounting base and force transmission path. The support rod 129 extends vertically or at an angle to ensure that the brush body 131 can cover the upper surface of the part and the critical area around the orifice.

[0055] The brush body 131 is slidably sleeved on the support rod 129 and can move freely along the axial direction of the support rod 129. The brush body 131 is typically composed of a wear-resistant engineering plastic or metal skeleton combined with high-density nylon, polyester, or steel wire bristles. The bristles are arranged facing the conveyor belt 107 or the surface of the part, possessing good flexibility and scraping ability, effectively removing fine debris without scratching the surface of the part. In addition, the brush body 131 has guide holes or sliding sleeves that match the support rod 129 to ensure smooth and unbiased movement.

[0056] The elastic element 130 is disposed between the support rod 129 and the brush body 131, serving to buffer, compress, and self-adjust. This elastic element 130 can be a compression spring, disc spring, rubber washer, or polyurethane elastomer, etc., with one end abutting against the limiting step or fixing ring on the support rod 129, and the other end acting on the inner cavity end face of the brush body 131. In its natural state, the elastic element 130 is in a pre-compressed state, continuously applying a downward elastic force to the brush body 131, ensuring it always conforms to the surface to be cleaned.

[0057] After the lifting plate 113 drives the entire drilling assembly 104 to descend and complete the drilling, during the return stroke, the brush body 131 maintains contact pressure with the surface of the part under the action of the elastic element 130, and cleans the surface of the valve component as the valve component rotates.

[0058] The collection assembly 105 includes a collection platform 132, a rotating rod 133, a third motor 134, and a collection box 135. The rotating rod 133 is rotatably mounted on one side of the base 101. The collection platform 132 is fixed to the top of the rotating rod 133 and is used to collect the waste generated during drilling. The third motor 134 is used to drive the rotating rod 133 to rotate. The collection box 135 is fixed to the base 101 and is used to collect the waste discharged from the collection platform 132.

[0059] The rotating rod 133 is vertically or inclinedly rotatably mounted on one side of the base 101. Its lower end is rotatably connected to the base 101 via a bearing seat or bushing, while the upper end is fixedly mounted with the collection platform 132. The third motor 134 is fixed to the base 101 or the frame, and its output shaft is connected to the lower end of the rotating rod 133 via a coupling, gear pair, or sprocket transmission mechanism to drive the rotating rod 133 to rotate around its axis. After the drilling operation is completed, the control system can automatically start the third motor 134, driving the rotating rod 133 and the collection platform 132 above to rotate synchronously at a certain angle (usually 30°–90°), thereby dumping the metal scraps accumulated on the collection platform 132 into the collection box 135 below, realizing automatic unloading of waste scraps.

[0060] The collection box 135 is fixedly installed on the base 101, located directly below the tilting path of the collection platform 132. It adopts a drawer-type, barrel-shaped, or box-shaped structure for easy periodic removal and centralized disposal of waste. The inner wall of the collection box 135 may be equipped with a splash guard or buffer pad to reduce splashing and noise when waste falls.

[0061] The collection platform 132 includes a platform body 136, a sealing plate 137, and a counterweight 138. The platform body 136 is fixed on the rotating rod 133. The sealing plate 137 is rotatably connected to the platform body 136 and is located on one side of the platform body 136. The counterweight 138 is fixed on the sealing plate 137.

[0062] The platform 136 is a disc-shaped or trough-shaped component with a concave cavity structure, fixedly installed on the top of the rotating rod 133, used to catch metal debris falling from the drilling area. The edge of the platform 136 is slightly higher than the central area, forming a slightly inclined guide surface, which helps the debris to naturally converge to the center and avoid overflow.

[0063] A sealing plate 137 is provided on the side of the platform 136 near the conveyor belt 107 or the drilling station. The sealing plate 137 is rotatably connected to the platform 136 via a hinge, pivot, or other hinge, and can switch between "closed" and "open" states. When the equipment is in normal drilling mode, the sealing plate 137 hangs down naturally under the action of gravity or counterweight, closely adhering to the side edge of the platform 136 to form a closed barrier, preventing waste chips from splashing or falling from the side. When chip removal is required, as the collection platform 132 is rotated as a whole, the sealing plate 137 continues to maintain a downward posture due to inertia or the action of the counterweight 138, thus automatically opening during the tilting process, allowing the waste chips to smoothly slide into the collection box 135.

[0064] To ensure reliable closure of the sealing plate 137 in a non-tilting state, the counterweight 138 is fixed to the outer bottom of the sealing plate 137. The counterweight 138 is typically made of high-density metal (such as cast iron or steel), and its weight is precisely calculated to ensure stable closure of the sealing plate 137 when stationary, without affecting the driving load of the rotating rod 133 or causing structural fatigue due to excessive weight.

[0065] The collection platform 132 also includes a sealing strip 139, which is fixed to the side of the platform body 136 near the sealing plate.

[0066] The sealing strip 139 is preferably made of oil-resistant and wear-resistant rubber or silicone, and is fixedly installed on the contact surface of the platform 136 near the sealing plate 137 (i.e., "sealing plate" should be "sealing plate 137", corrected here for context). When the sealing plate 137 is closed, the sealing strip 139 is deformed under pressure, filling the gap between the two, forming an effective physical seal, significantly reducing the risk of dust diffusion, improving the workshop working environment, and meeting the relevant requirements of green manufacturing and occupational health and safety.

[0067] Second Embodiment Please see Figure 8 The present invention also provides a drilling method for processing valve components, comprising: S201 places the valve components onto the conveyor belt 107 for transport; Operators or upstream automated equipment (such as robotic arms, vibratory feeders, etc.) place the valve components to be processed in an orderly manner at the starting end of conveyor belt 107. Driven by a drive mechanism (such as a servo motor or geared motor), conveyor belt 107 runs at a uniform speed, smoothly transporting the components along a preset path to the drilling station. During this process, the support plates 106 and guide plates on both sides of conveyor belt 107 perform initial positioning and attitude correction of the components, ensuring they enter subsequent processes with the correct orientation and position, avoiding clamping failure or drilling deviation due to skewness or misalignment.

[0068] After the valve components are moved to the designated position, the first motor 110 is started to drive the two clamping plates 108 to position the valve components. When a sensor (such as a photoelectric switch, vision recognition system, or encoder) detects that the valve component has accurately reached the preset drilling position, the control system issues a command to start the first motor 110. The first motor 110 drives the first screw 109, which has a double-stage reverse thread, to rotate, causing the two clamping plates 108 connected to it to move synchronously towards each other along the conveyor belt, flexibly clamping the valve component from both sides. The clamping force can be adjusted according to the material and size of the part through program preset or real-time feedback, ensuring stable positioning while avoiding damage to the workpiece surface. After clamping, the component is precisely fixed on the drilling center reference line, providing high repeatability positioning accuracy for subsequent multi-hole drilling.

[0069] S203 starts the lifting cylinder 111 to drive the drill bit 116 to move down to drill holes, and adjusts the drilling position through the second motor 112 to drill multiple drilling positions. The brush 117 cleans the surface of the valve components during rotation. After clamping, the control system sequentially activates the lifting cylinder 111 and the second motor 112. The lifting cylinder 111 pushes the second motor 112 and the lifting plate 113 connected to it to descend vertically, causing the drill bits 116 mounted on multiple mounting seats 114 to simultaneously approach the workpiece surface. At the same time, the second motor 112 rotates at high speed, driving each drill bit 116 to perform cutting operations. For situations where multiple holes need to be drilled at different locations, the system can first complete the drilling of one hole, and then change the radial or circumferential layout of each mounting seat 114 through the adjuster 115 (or the fine-tuning mechanism in conjunction with the second motor 112) before positioning and drilling the next hole, achieving multi-hole automatic processing in one go or in steps.

[0070] During or after drilling, as the lifting plate 113 rises, the brush 117 integrated on the lifting plate 113 moves synchronously. Since the brush body 131 is floatingly mounted on the support rod 129 via the elastic element 130, it maintains light contact with the valve component surface during the lifting motion. As the lifting plate 113 moves up and down, the brush 117 reciprocates by scraping the upper surface of the part and the area around the orifice, promptly removing attached metal debris, burrs, and coolant residue to prevent them from affecting subsequent measurements, assembly, or causing secondary scratches, thus ensuring the cleanliness of the machined surface.

[0071] The collection component 105 described in S204 collects the waste generated during drilling.

[0072] Metal scrap generated during drilling falls naturally under gravity, first settling onto the collection platform 132 located directly below the drilling station. The concave structure of the platform 132's body 136 effectively collects the scrap, while the sealing plate 137 remains closed under the action of the counterweight 138, preventing scrap from spilling out. When a batch of processing is completed or the scrap accumulation on the collection platform 132 reaches a set amount, the control system activates the third motor 134, driving the rotating rod 133 to rotate the entire collection platform 132 at a certain angle. At this time, the sealing plate 137 automatically opens due to the counterweight, and the scrap slides into the fixed collection box 135 below. The sealing strip 139 ensures a tight seal between the platform 136 and the sealing plate 137 when not tilted, effectively suppressing dust dispersion and achieving environmentally friendly and clean scrap management.

[0073] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
