Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to a drilling device for large workpieces with self-recovering cutting fluid. Background Technology

[0002] In industries such as machinery manufacturing, construction machinery, and heavy equipment, drilling of large workpieces (such as machine tool beds, heavy machinery housings, and large structural components) is one of the key processes. During drilling, a large amount of heat is generated at the cutting contact surface between the drill bit and the workpiece, accompanied by intense friction. To reduce cutting temperature, minimize tool wear, and improve the machining accuracy and surface quality of the hole wall, cutting fluid must be continuously supplied to the machining area to achieve cooling, lubrication, and chip removal functions.

[0003] Existing cutting fluid supply systems for drilling large workpieces mostly employ external spray structures, using fixed or adjustable nozzles to directionally spray cutting fluid onto the cutting area between the drill bit and the workpiece. However, due to the generally large size, weight, and irregular shape of large workpieces, complex support and positioning mechanisms are required for fixation during machining. This causes the cutting fluid to easily flow along the workpiece surface, gaps in the support structure, and the equipment's worktable after spraying, making centralized collection difficult. The aforementioned existing technologies result in severe cutting fluid spillage, with a large amount of unrecovered cutting fluid being directly wasted, significantly increasing processing costs. Furthermore, spilled cutting fluid can easily seep into electrical control boxes, wiring interfaces, drive motors, and other electrical components, causing water damage and short circuits, leading to equipment malfunctions and downtime, and even damage to core components. Simultaneously, residual cutting fluid on the operating area creates a slippery surface, significantly increasing the risk of slips and falls for operators, posing a safety hazard due to cutting fluid contact with the human body and threatening personal safety. Utility Model Content

[0004] To overcome the above-mentioned defects, the present invention provides a cutting fluid self-recovery drilling device for large workpieces, which solves the technical problem that the cutting fluid in the existing large workpiece drilling devices is seriously spilled, which not only causes waste, but also easily causes electrical circuits to be submerged in water and short-circuit, posing a personal safety hazard.

[0005] According to one aspect, at least one embodiment of the present invention provides a drilling device for large workpieces with self-recovering cutting fluid, comprising: A drilling unit, wherein a circulation tank for storing cutting fluid is provided on the drilling unit; A machining table is provided on one side of the drilling unit to support and fix the workpiece to be processed. A liquid collection tank is provided on the surface of the machining table, and a liquid outlet is provided through the bottom of the liquid collection tank. A flow guiding hose is sealed and connected to the liquid outlet. The end of the flow guiding hose away from the liquid outlet extends to the top of the circulation tank to guide the cutting fluid collected in the liquid collection tank into the circulation tank.

[0006] For example, in a cutting fluid self-recovery drilling device for large workpieces provided in at least one embodiment of the present invention, the longitudinal section of the fluid collection tank is an inverted cone shape.

[0007] For example, in a cutting fluid self-recovery drilling device for large workpieces provided in at least one embodiment of the present invention, a filter chip plate is provided above the fluid collection tank, and the filter chip plate is used to support the workpiece to be processed.

[0008] For example, in a cutting fluid self-recovery drilling device for large workpieces provided in at least one embodiment of the present invention, the machining table is slidably disposed on one side of the drilling unit.

[0009] For example, in a cutting fluid self-recovery drilling device for large workpieces provided in at least one embodiment of the present invention, a support mechanism is provided between the processing table and the drilling unit, and the flow guiding hose is provided on the support mechanism.

[0010] For example, in a cutting fluid self-recovery drilling device for large workpieces provided in at least one embodiment of this utility model, the support mechanism includes: An installation pile is placed between the drilling unit and the processing table; A support slide rod is slidably connected to the mounting pile and can slide close to the drilling unit or the processing table; The support swing arm has one end swingably connected to the end of the support slide rod away from the drilling unit, and the other end swingably connected to the bottom of the processing table.

[0011] For example, in a cutting fluid self-recovery drilling device for large workpieces provided in at least one embodiment of this utility model, the drilling unit includes: The base, on which the circulation groove is formed; A drilling mechanism, mounted on the base, is used for drilling holes in the workpiece.

[0012] For example, in a cutting fluid self-recovery drilling device for large workpieces provided in at least one embodiment of the present invention, the drilling mechanism is rotatably connected to the base.

[0013] For example, in a cutting fluid self-recovery drilling device for large workpieces provided in at least one embodiment of the present invention, the end of the support rocker arm away from the support slide bar is hinged to the outer peripheral wall of the fluid outlet.

[0014] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the processing table is located on one side of the drilling unit and supports and fixes the workpiece to be processed. The liquid collection tank opened on its table surface covers the area where the cutting fluid may flow, realizing the centralized collection of cutting fluid from the source and completely solving the problem of cutting fluid flowing everywhere along the workpiece surface and equipment table surface in the prior art.

[0015] The outlet at the bottom of the collection tank provides a centralized outlet channel for the cutting fluid. The guide hose is sealed to the outlet, creating a closed directional transmission path from the collection tank to the circulation tank. This effectively prevents leakage of the cutting fluid during transmission and avoids it from seeping into areas such as the equipment's electrical control box, wiring interfaces, and drive motor. This reduces equipment failures caused by water immersion and short circuits in the electrical wiring and protects core components.

[0016] The end of the guide hose away from the outlet extends to the top of the circulation tank, allowing the collected cutting fluid to flow directly back into the circulation tank for storage, realizing the recycling and reuse of cutting fluid, greatly reducing waste caused by non-recycling, and lowering processing costs.

[0017] A closed recovery path prevents cutting fluid residue from remaining on the operating area floor, eliminating the risk of slipping and falling on wet floors, reducing the safety hazards of cutting fluid contact with the human body, and ensuring personal safety. Attached Figure Description

[0026] The cutting fluid self-recovery drilling device for large workpieces provided in this embodiment is suitable for drilling large workpieces such as machine tool beds, heavy machinery housings, and large structural components in industries such as machinery manufacturing, construction machinery, and heavy equipment. In these industries, drilling large workpieces is one of the key processes. During drilling, a large amount of heat is generated at the cutting contact surface between the drill bit and the workpiece, accompanied by friction. A continuous supply of cutting fluid is crucial for reducing cutting temperature, minimizing tool wear, and improving hole wall machining accuracy and surface quality. Existing cutting fluid supply systems for large workpiece drilling devices mostly adopt an external spray structure, which allows cutting fluid to easily flow along the workpiece surface, support structure gaps, and equipment worktable, making collection difficult and leading to cutting fluid waste, equipment failure, and personal safety hazards. This device solves these problems by integrating the drilling unit, machining table, and guide hoses into a self-recovery cutting fluid system.

[0027] like Figure 1 As shown, the overall structure of this device is centered around the drilling unit 1 and the machining table 2. The two are positioned relative to each other through an installation structure, working together to complete the drilling of large workpieces and the recovery of cutting fluid. The drilling unit 1, as the core processing component, provides power support for the drilling operation. The machining table 2 is arranged on one side of the drilling unit 1 to support and fix the workpiece 100 to be processed. The layout of the two not only ensures the processing operation but also provides a basis for the construction of the cutting fluid recovery path.

[0028] The specific structure of drilling unit 1 is as follows: Figure 1 As shown, the system includes a base 12 and a drilling mechanism 13. The base 12, as a fundamental load-bearing component, is fixedly installed on the working surface or a dedicated bracket, providing support for the entire drilling unit 1 and ensuring structural stability during drilling. A circulation tank 11 is formed on the upper surface of the base 12, creating a tank structure for storing cutting fluid. It serves as both a supply source and a storage area for the recovered cutting fluid, and its location is adapted to the cutting fluid supply requirements of the drilling mechanism 13, shortening the cutting fluid transmission path. The drilling mechanism 13 is mounted on the upper surface of the base 12 and consists of a power source and a drill bit. The power source can be a motor, with its output fixedly connected to the drill bit. The motor drives the drill bit to rotate, achieving drilling of the workpiece 100. To accommodate drilling at different angles, the drilling mechanism 13 is rotatably connected to the base 12. Specifically, a rotating shaft can be fixedly installed on the base 12, with the bottom of the drilling mechanism 13 hinged to the rotating shaft. The axis of the rotating shaft is perpendicular to the upper surface of the base 12, allowing the drilling mechanism 13 to rotate around the shaft to adjust the drilling angle. After the angle adjustment is completed, the drilling mechanism 13 is fixed in position by using bolts or pins to lock the corresponding mounting holes of the drilling mechanism 13 and the base 12, thus ensuring machining accuracy.

[0029] The structural design of machining table 2 revolves around workpiece support and cutting fluid collection, such as... Figure 1As shown, the table surface of machining table 2 serves as a bearing surface for placing the workpiece 100 to be processed. A fluid collection tank 21 is provided on the table surface, covering all areas on machining table 2 where cutting fluid may flow, ensuring that all used cutting fluid flows into the collection tank 21. The longitudinal section of the collection tank 21 is an inverted cone shape, with the tank wall extending sloping towards the bottom along the table surface of machining table 2. The upper end diameter is larger than the lower end diameter, and the tank wall transitions seamlessly with the bottom. Gravity is used to promote the convergence of cutting fluid towards the bottom of the tank, reducing the retention of cutting fluid in the tank.

[0030] The bottom of the liquid collection tank 21 is provided with a liquid outlet 22, which is a through hole structure that penetrates the thickness direction of the machining table 2. It serves as a centralized outlet channel for cutting fluid, and its diameter is adapted to the connection requirements of the guide hose 3.

[0031] like Figure 1 and Figure 2 As shown, a filter plate 4 is installed above the liquid collection tank 21, covering the opening of the liquid collection tank 21. The edge of the filter plate 4 is fixedly connected to the table surface of the machining table 2 to form a support surface. Several filter holes are opened through the filter plate 4. The diameter of the filter holes is smaller than the size of the chips generated by drilling. The workpiece 100 to be processed is placed on the upper surface of the filter plate 4 and positioned by a fixing structure such as a pressure plate and a clamp. This ensures the condition of the workpiece 100 during processing and allows the cutting fluid to flow into the liquid collection tank 21 through the filter holes. At the same time, the chips are trapped on the upper surface of the filter plate 4, achieving the initial separation of cutting fluid and chips.

[0032] The machining table 2 is slidably positioned to move closer to or further away from the drilling unit 1, specifically through a guide rail slider mechanism. A guide rail is fixedly installed on the side of the drilling unit 1 closest to the machining table 2, extending along a preset direction. A slider is fixedly installed on the bottom of the machining table 2, sliding in cooperation with the guide rail to form a sliding guide structure. To achieve automatic movement of the machining table 2, a drive unit can be installed on one side of the guide rail. The drive unit can be a cylinder or a lead screw and nut mechanism. The fixed end of the drive unit is connected to the drilling unit 1 or a ground support, and the output end is fixedly connected to the machining table 2. Through the power output of the drive unit, the machining table 2 slides along the guide rail, meeting the processing needs of workpieces of different sizes or different drilling positions on the same workpiece.

[0033] like Figure 1 and Figure 3As shown, a support mechanism 5 is provided between the processing table 2 and the drilling unit 1. The flow guide hose 3 is installed on the support mechanism 5 by fasteners such as clamps to support the flow guide hose 3. The support mechanism 5 includes a mounting pile 51, a support slide rod 52, and a support swing rod 53. The mounting pile 51 is a columnar structure and is fixedly set on the ground or base 12 between the drilling unit 1 and the processing table 2, serving as the mounting foundation for the support slide rod 52. The support slide rod 52 is a rod-shaped structure, with one end inserted into the mounting pile 51, forming a sliding fit with the mounting pile 51, allowing it to slide horizontally along the mounting pile 51 to move closer to or away from the drilling unit 1. The support swing rod 53 is a rod-shaped structure, with one end connected to the end of the support slide rod 52 away from the mounting pile 51 via a hinge shaft, and the other end hinged to the outer peripheral wall of the outlet 22 via a hinge shaft. The outer peripheral wall of the outlet 22 is provided with a protruding connecting lug, and the hinge shaft passes through the connecting lug and the end of the support swing rod 53 to ensure the swing connection state. This structural design allows the support mechanism 5 to adjust its shape as the processing table 2 slides, always providing support for the flow guide hose 3.

[0034] One end of the guide hose 3 is sealed to the inner wall of the outlet 22 to ensure no leakage during the transfer of cutting fluid. The other end extends above the circulation tank 11, with its port facing the opening of the circulation tank 11, forming a flow channel from the outlet 22 to the circulation tank 11. The length of the guide hose 3 is adapted to the maximum sliding stroke of the machining table 2, ensuring that when the machining table 2 slides to its limit position, the guide hose 3 can still maintain a sealed connection with the outlet 22 and extend into the circulation tank 11 without being pulled or damaged.

[0035] The working process of this device is as follows: Before use, inject sufficient cutting fluid into the circulation tank 11. According to the size of the workpiece 100 to be processed and the drilling position requirements, start the drive to drive the processing table 2 to slide along the guide rail to the preset position, and fix the processing table 2 by the locking component. Place the workpiece 100 to be processed on the chip filter plate 4, and use the fixing structure to lock and position the workpiece 100 to ensure that no displacement occurs during processing. Loosen the locking component of the drilling mechanism 13, rotate the drilling mechanism 13 around the rotating shaft, adjust to the drilling angle, and then relock the drilling mechanism 13.

[0036] The power source of the drilling mechanism 13 is activated, driving the drill bit to rotate. Simultaneously, the cutting fluid in the circulation tank 11 is delivered to the cutting area between the drill bit and the workpiece 100 through a pre-set fluid supply pipeline, achieving cooling, lubrication, and chip removal functions. After use, the cutting fluid carries the chips along the surface of the workpiece 100 to the chip filter plate 4. The cutting fluid flows into the collection tank 21 through the filter holes, while the chips are blocked by the filter holes and retained on the upper surface of the chip filter plate 4. These chips can then be removed manually or by other existing automatic chip removal structures.

[0037] Under the influence of gravity, the cutting fluid in the collection tank 21 flows along the inverted conical tank wall towards the bottom of the tank and flows into the guide hose 3 through the outlet 22. Since the guide hose 3 is kept unobstructed by the support mechanism 5 and is sealed to the outlet 22, the cutting fluid is directionally transported through the guide hose 3 and finally flows into the circulation tank 11 for recycling. The recycled cutting fluid can be transported back to the cutting area through the supply pipeline to achieve recycling.

[0038] When the position of machining table 2 needs to be adjusted, the locking device is released, and the drive mechanism is activated to move machining table 2 along the guide rail. During the movement of machining table 2, the support swing rod 53 swings around the hinge axis at the fluid outlet 22. The swing of the support swing rod 53 drives the support slide rod 52 to slide along the axial direction of the mounting pile 51. Through the coordinated cooperation of sliding and swinging, the support mechanism 5 adjusts its length and angle. The guide hose 3 moves synchronously with the support mechanism 5, always maintaining the integrity of the sealed connection and the guide channel, and the cutting fluid recovery function is not affected.

[0039] The base 12 provides support for the drilling mechanism 13, ensuring the accuracy of drilling. It also provides a mounting base for the circulation tank 11, shortening the distance between the circulation tank 11 and the drilling mechanism 13, reducing transmission losses during the supply and recovery of cutting fluid, and improving circulation efficiency. The rotatable connection between the drilling mechanism 13 and the base 12 expands the processing range of the device, adapting to drilling requirements at different angles, allowing processing to be completed without changing equipment.

[0040] The sliding structure of the machining table 2 enhances the adaptability of the device, enabling it to meet the machining needs of workpieces of different sizes and different drilling positions on the same workpiece. Combined with the drive components, it achieves automatic adjustment, improving machining efficiency. The chip filter plate 4 provides both workpiece support and chip separation, preventing chips from flowing into the fluid collection tank 21 and clogging the outlet 22 or the guide hose 3, ensuring the unobstructed flow of the recovery channel, and reducing the impact of chips on the recycling of the cutting fluid.

[0041] The inverted conical structure of the fluid collection tank 21 utilizes gravity to promote the convergence of cutting fluid, reducing fluid retention within the tank and improving collection efficiency. Combined with the covering design of the filter plate 4, it prevents impurities generated during workpiece machining from directly entering the fluid collection tank 21, maintaining its cleanliness. The support mechanism 5, through the coordinated action of the mounting pile 51, support slide rod 52, and support swing rod 53, supports the guide hose 3, preventing it from sagging due to its own weight or being pulled or bent by the movement of the machining table 2. This ensures the continuous unobstructed flow channel while reducing friction between the guide hose 3 and surrounding structures, lowering the risk of breakage.

[0042] The hinged connection between the support rod 53 and the outlet 22 allows the support force to act directly on the outlet 22 area, enhancing the connection strength between the outlet 22 and the processing table 2. This prevents the outlet 22 from loosening due to long-term stress from the guide hose 3 and the cutting fluid, thus improving structural stability. Furthermore, the hinge point avoids the sealing area between the guide hose 3 and the outlet 22, so it does not affect the sealing effect.

[0043] The sealed connection between the guide hose 3 and the outlet 22, and its extension into the circulation tank 11, creates a closed cutting fluid recovery channel. Combined with the collection function of the collection tank 21, this enables centralized recovery and reuse of the cutting fluid, reducing waste caused by unrecovered fluid and lowering processing costs. Simultaneously, the closed recovery channel blocks the path of cutting fluid spillage, preventing it from seeping into electrical control boxes, wiring interfaces, drive motors, and other electrical components, thus reducing equipment failures caused by water-damaged short circuits and protecting core components. Centralized cutting fluid recovery also prevents residual cutting fluid on the operating area floor, reducing the risk of slips and falls for operators, minimizing safety hazards caused by cutting fluid contact with the human body, and ensuring personal safety.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
