Description

Technical Field

[0001] The invention relates to the technical field of cast iron grate structural component processing, in particular to a drilling and polishing integrated combined processing device for the production of cast iron grate structural components. Background Art

[0002] The integrated drilling and polishing combined processing device for the production of cast iron grate structural parts is a mechanical equipment that integrates the drilling and polishing processes. It can complete the drilling and polishing processing of cast iron grate structural parts in one clamping, thereby improving processing efficiency and precision.

[0003] Referring to Chinese Patent Publication No. CN111745409B, a multifunctional processing device for aluminum profile processing is disclosed. When in use, the second motor is driven, the drill rod rotates to drill the side end of the positioning block to form a positioning hole. At the same time, the first motor is driven, the first ball screw assembly drives the first connecting plate and the second motor to move in the direction of the first slide rail, which can adjust the depth of the drilling, facilitate operation, and improve efficiency. At the same time, the third motor is driven, the polishing wheel rotates to polish the upper end of the positioning block. At the same time, the first cylinder is driven, the C-shaped fixed plate drives the third motor to slide in the direction of the second slide rail, and the height of the polishing wheel can be adjusted. The degree of polishing of the positioning block can be adjusted, which facilitates operation and improves efficiency. The present invention is also designed with a transfer device, which drives the positioning plate to be transferred to the transport track through a vacuum suction nozzle, thereby realizing processing and transportation. The present invention integrates drilling, polishing, and transfer into an integrated operation, saving costs and improving production efficiency.

[0004] The four corners of the base plate of the cast iron grate structure are often drilled, and the clamping parts and debris collection parts are often separated from each other, and drilling and polishing are carried out separately. The drilling process may produce long iron chips, which will be wrapped around the drill bit or rotate with the drill rod, making it difficult for the collection device to capture them. During polishing, the debris will be splashed everywhere due to the centrifugal force generated by the high-speed rotation of the polishing wheel. Some debris may adhere to the surface of the main plate or the inner wall of the equipment, making it difficult to be effectively absorbed by the dust collector or collection device. The amount of debris generated during the processing is large and widely distributed. The collection device may not be able to handle it in time, causing some debris to accumulate on the workbench or scatter around the equipment, affecting the processing environment and subsequent cleanup work. In order to improve the debris absorption effect, some devices will adopt complex structures and filtration systems, which increases the cost and difficulty of equipment maintenance.

[0014] Beneficial Effects: This invention provides an integrated drilling and polishing combined processing device for the production of cast iron grate structural components. Compared with existing technologies, it has the following advantages: 1. All cover boxes are controlled by pneumatics to simultaneously accommodate and secure the footplates, forming an isolation barrier. A seesaw mechanism controls the opening and closing of the top or bottom holes of the cover boxes. Only one side of the cover box is connected to the outside world at a time, facilitating the collection of debris during drilling or polishing.

[0015] 2. The workpiece is horizontally restrained by the contact between the foot plate and the inner wall of the cover box, and the contact between the friction frame and the side of the main plate.

[0041] Two said hinged plates 66 and the rotating drum 67 form an inclined hinged plate, both ends of the inclined hinged plate are connected with the plug-in sealing plate 61, when the plug-in sealing plate 61 at the top end of the inclined hinged plate is plugged with the first jack 44, the plug-in sealing plate 61 at the bottom end of the inclined hinged plate is away from the second jack 46, the bottom hole 47 is communicated with the lower cavity through the second jack 46, when the plug-in sealing plate 61 at the bottom end of the inclined hinged plate is plugged with the second jack 46, the plug-in sealing plate 61 at the top end of the inclined hinged plate is away from the first jack 44, the top hole 45 is communicated with the lower cavity through the first jack 44.

[0042] The pulling device 8 comprises a motor 84, a fixed end of the motor 84 is connected with the side of the cover box 41 through the second connecting plate 71, a rotating end of the motor 84 is connected with a rotating shaft 83, the side of the rotating shaft 83 is connected with a plurality of rope bodies 81, a winding rod 82 is arranged between the motor 84 and the cover box 41, both ends of the winding rod 82 are connected with the side of the cover box 41 through the third connecting plate 72, each of the rope bodies 81 is wound with the winding rod 82, one end of each of the rope bodies 81 is wound around the winding rod 82 and connected with one side of a hinged plate 66, the other hinged plate 66 is connected with a baffle 85 through the second spring 86, the baffle 85 is connected with the second connecting plate 71.

[0043] In use, the main plate 17 is placed on the platform formed by the horizontal plate 22 and the vertical plate 21, so that the edges of the foot plates 18 coincide with the edges of the platform, at this time, the foot plates 18 are all placed on the polishing angle 25.

[0044] When the fan 34 is started, the wind from the fan 34 enters all the cylinders 51 through the wind box 35 and the air duct 36 in turn. The wind pressure in the cylinder 51 increases, and the pressure on the wind cover 54 increases. Each wind cover 54 moves with the shift rod 55 and the cover box 41 toward the direction close to the foot plate 18. A slide groove is provided between the two inner plates 48 at one end of the cover box 41. The foot plate 18 approaches the slide groove and is slidably connected to the slide groove. One end of the foot plate 18 continues to enter the cover box 41 until the foot plate 18 completely enters the cover box 41. At this time, one end of the foot plate 18 abuts against the inner wall of the cover box 41, and the friction frame 49 is pressed against the surface of the main plate 17. The friction frame 49 is an elastic rubber plate. The elastic rubber plate can adapt to the slight unevenness on the surface of the main plate 17 through its own deformation, such as casting defects of the cast iron grate and the lines left by processing. Under the action of pressure, it forms close contact with the surface of the main plate 17 to reduce gaps. The elasticity of the rubber can absorb the impact force during crimping, preventing the rigid contact from causing scratches, indentations or deformation on the surface of the main plate 17, and can effectively reduce the risk of damage caused by excessive pressure. In actual production, there may be slight tolerances in the size of the main plate 17, or there may be slight deviations between the installation position of the friction frame 49 and the equipment. The elastic rubber plate can compensate for these errors through deformation to ensure a stable crimping state. The rubber material itself has a high coefficient of friction, which can generate greater static friction with the surface of the main plate 17 during crimping, helping the main plate 17 to remain stable during processing and reduce sliding or displacement.

[0045] By controlling the opening and closing of the fan 34 and simultaneously controlling the horizontal movement of all the cover boxes 41, all the foot plates 18 at the bottom of the main plate 17 are simultaneously inserted into the cover boxes 41 and secured. The main plate 17 and the foot plates 18 form a workpiece. The workpiece is horizontally restrained by the contact between the foot plates 18 and the inner wall of the cover box 41 and the contact between the friction frame 49 and the side of the main plate 17. The two inner plates 48 form a chute, which is slidably connected to the foot plates 18, and the workpiece is vertically restrained, thereby securing the workpiece. This simple and efficient fixing method facilitates installation and replacement, improving work efficiency. Furthermore, by accommodating the foot plates 18 in the cover boxes 41, a relatively sealed space is created for the foot plates 18, facilitating the subsequent storage and collection of debris.

[0046] Before drilling, start the motor 84, the rotating end of the motor 84 rotates with the rotating shaft 83, the rotating shaft 83 starts to wind the rope body 81, the length of the rope body 81 between the two bent plates 66 and the winding rod 82 is shortened, the two bent plates 66 and the rotating drum 67 form an inclined bent plate, the inclined bent plate can only rotate along the third rotating rod 68, the top end of the inclined bent plate rotates towards the direction close to the winding rod 82, the first rotating rod 62 is movably connected with the second rotating rod 64 through the first connecting plate 63, the second rotating rod 64 can rotate around the circumference of the first rotating rod 62 through the first connecting plate 63, and the first rotating rod 62, the first connecting plate 63 and the second rotating rod 64 form a movable connecting piece. The movable connecting piece changes its angle by flexible rotation to adapt to the movement of the inclined bent plate and the plug-in sealing plate 61. With the movement of the inclined bent plate, the plug-in sealing plate 61 at the top end of the inclined bent plate is continuously pulled out of the first insertion hole 44, and the plug-in sealing plate 61 at the bottom end of the inclined bent plate is continuously inserted into the second insertion hole 46, and the second spring 86 is stretched. When the motor 84 stops rotating, the plug-in sealing plate 61 at the bottom end of the inclined bent plate is completely inserted into the second insertion hole 46 and seals the second insertion hole 46, the plug-in sealing plate 61 separates the lower cavity from the bottom hole 47, the bottom hole 47 and the lower cavity cannot be connected through the second insertion hole 46, and the sealing of the bottom of the cover box 41 is completed; the plug-in sealing plate 61 at the top end of the inclined bent plate is mostly pulled out of the first insertion hole 44, and part of the plug-in sealing plate 61 is located in the first insertion hole 44. The first insertion hole 44 or the second insertion hole 46 not only inserts with the plug-in sealing plate 61, but also limits the movement of the plug-in sealing plate 61, the plug-in sealing plate 61 no longer seals the first insertion hole 44, the first insertion hole 44 is completely opened, the top hole 45 is connected with the upper cavity through the first insertion hole 44, and the top of the cover box 41 is opened.

[0047] Start the drilling part 11, the bottom end of the drilling part 11 passes through the top hole 45, the first insertion hole 44 in turn and enters the upper cavity, the drill bit contacts the foot plate 18 and drills, a large amount of metal debris generated by drilling splashes everywhere in the upper cavity of the cover box 41, the cover box 41 forms a physical barrier, which can completely limit the debris in the closed space, fundamentally avoiding the debris splashing at high speed to the hands, face or clothes of the operator during drilling, eliminating the safety hazards of scratches and burns. The constraint in the cover box 41 can keep the surrounding environment clean, reduce the cleaning burden, reduce the probability of small debris spreading into the air, and reduce the risk of respiratory health; the cover box 41 limits the debris in the upper cavity, which can prevent it from invading the core area of the equipment and prolong the service life of the equipment; if there are other foot plates 18, accessories or precision parts to be processed outside the cover box 41, the splashing of debris may cause the surface of these parts to be scratched and contaminated, affecting the subsequent processing or assembly quality. The constraint of the cover box 41 can avoid such cross contamination; after the debris is limited in the cover box 41, it is not necessary to clean the debris scattered around the equipment or on the ground, but only to concentrate on the inside of the cover box 41, reducing the cleaning time and workload, which is suitable for batch production scenes; the debris in the cover box 41 is relatively concentrated and not easy to mix with dust, oil stains and other impurities, facilitating subsequent recycling (such as metal smelting) and improving resource recycling efficiency.

[0048] Start the vacuum cleaner, which will promptly suck away the small metal particles in the upper cavity, reduce the amount of metal debris remaining in the upper cavity and on the surface of the workpiece, and suck away the debris accumulated near the drilling position to ensure that the contact area between the drill bit and the workpiece is clean, ensuring drilling accuracy, and preventing the fine metal dust generated by drilling from floating in the air for a long time to prevent the operator from inhaling it, which may cause respiratory diseases.

[0049] After drilling is complete and before polishing, the motor 84 is started, driving the shaft 83 in the opposite direction. The rope 81 on the shaft 83 is continuously released, and the top of the bevel is no longer tightened by the rope 81. The rope 81 between the top of the bevel and the shaft 83 relaxes, causing the second spring 86 to recover. Under the tension of the second spring 86, the bottom of the bevel moves toward the baffle 85. The sealing plate 61 at the top of the bevel is inserted into the first insertion hole 44, sealing the first insertion hole 44. The sealing plate 61 at the bottom of the bevel is withdrawn from the second insertion hole 46, and the bottom hole 47 is connected to the lower chamber through the second insertion hole 46.

[0050] By bidirectional rotation of the motor 84, the connection relationship between the first insertion hole 44 or the second insertion hole 46 and its corresponding plug-in sealing plate 61 is controlled respectively, thereby controlling the opening and closing of the top or bottom channel of the cover box 41. Only one of the top hole 45 or the bottom hole 47 is opened at a time, thereby improving the overall sealing of the cover box 41. Only the processing side is opened to cooperate with drilling or polishing work.

[0051] The third hydraulic cylinder 32 or the second hydraulic cylinder 31 is activated. The telescopic end of the third hydraulic cylinder 32 pushes the linkage plate 26, and the telescopic end of the second hydraulic cylinder 31 pushes the sliding plate 27. All the cover boxes 41 are connected as a whole through the linkage plate 26 and the sliding plate 27. The cover boxes 41 and the workpiece move with the telescopic end. The cover boxes 41 slide along the horizontal plate 22 or the vertical plate 21, completing the horizontal and vertical translation of the cover boxes 41. The foot plate 18 that has just been drilled is translated to a polishing angle 25. The first hydraulic cylinder 16 and the polishing member 15 are activated in sequence. The telescopic end of the first hydraulic cylinder 16 moves the polishing member 15 vertically upward, and the polishing member 15 polishes the inner wall of the end hole 19. The resulting fine metal debris is absorbed by the vacuum cleaner. The diameter of the metal debris particles produced by polishing is generally smaller than that produced by drilling. Therefore, the chip discharge pipe 9 is installed in the upper chamber to improve dust removal in the upper chamber. The required suction force for the lower chamber debris also allows the lower chamber debris to be absorbed (primarily absorbing fine metal dust particles; larger diameter metal particles can be collected in the cover box 41). Simultaneously, the other foot plate 18 moves directly below the drilling member 11, which continues drilling the foot plate 18. While drilling, the already drilled foot plate 18 is polished. This simultaneous drilling and polishing process improves work efficiency.

[0052] After all the foot plates 18 of the workpiece are drilled and polished, the blower 34 is turned off, all the cover boxes 41 are separated from the foot plates 18, and the large-diameter metal particles and metal fragments remaining in the cover boxes 41 are collected.

[0053] All the cover boxes 41 are controlled by pneumatic action to simultaneously accommodate and fix the foot plates 18 and form an isolation barrier. The opening and closing of the top hole 45 or the bottom hole 47 of the cover box 41 is controlled by the rocker 66 structure. Only one side of the cover box 41 is connected to the outside world at a time, which is convenient for collecting debris during drilling or polishing. The drilling and polishing of the two foot plates 18 are carried out simultaneously, thereby improving work efficiency.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
