Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to an oil immersion device for tool processing. Background Technology

[0002] In the field of machining, after use, cutting tools (such as drills, milling cutters, and taps) may have residual cutting fluid, moisture, or be directly exposed to air, making them prone to corrosion and affecting their precision and service life. To prevent corrosion, cutting tools are usually immersed in oil. Currently, the most common method of immersion is manual, where the cutting tool is directly immersed in an open oil drum or pan. This traditional method has many drawbacks: First, during repeated immersion, metal shavings and other impurities carried by the cutting tool will contaminate the entire oil tank, reducing the rust-preventive effect and shortening the oil's lifespan. Second, manual operation makes it difficult to ensure uniform immersion, easily resulting in insufficient immersion in some areas. Third, the open immersion environment easily leads to oil evaporation and contamination, affecting the working environment. In addition, existing immersion devices lack an effective filtration system, failing to remove impurities from the oil in a timely manner, causing a rapid decline in oil quality. Furthermore, traditional devices also suffer from inefficiency and inconvenience in tool transport and fixation. To address these issues, existing technologies urgently need improvement. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an oil immersion device for tool processing, which has the advantages of improving oil cleanliness, extending oil service life, enhancing oil immersion uniformity, and facilitating operation.

[0004] This application provides an oil immersion device for tool processing, the technical solution of which is as follows:

[0005] The device includes an oil immersion tank, a feeding assembly on the top of the tank, a filter assembly on the left side of the tank's interior, a filter box fixedly connected to the tank's interior, a filter screen on the right side of the filter box, a locking block at both ends of the filter screen, slots matching the locking blocks on both ends of the right side of the filter box, threaded sleeves at both ends of the top of the filter box, a screw threaded into the sleeves, a rotating plate on the left side of the screw, a movable shaft rotatably connected to the right side of the screw, a limit block on the right side of the movable shaft, a guide block at the bottom of the limit block, guide grooves matching the guide blocks on both ends of the top of the filter box, the limit block located at the top of the slots and locking blocks, a conveying pump on the left side of the tank, the pump's input end connected to the bottom of the left side of the tank, the pump's output end located above the filter box, and a drain outlet on the front of the tank.

[0006] Furthermore, this application also proposes that the feeding assembly includes a frame, and the frame is fitted at the center of the surface of the oil immersion tank. An electric push rod is provided at the top of the frame, and the output end of the electric push rod passes through and extends into the inner cavity of the frame to provide a conveying plate. The inner cavity of the conveying plate has not less than six hanging holes at equal intervals.

[0007] Furthermore, this application also proposes that both sides of the electric push rod are fixedly connected to a fixing frame, and the other end of the fixing frame is fixedly connected to the frame.

[0008] Furthermore, this application also proposes that the inner cavities at both ends of the frame are fitted with fixing bolts, and the inner side of the fixing bolts is threadedly connected to the oil immersion tank.

[0009] Furthermore, this application also proposes that pull plates are provided at both ends of the top of the filter screen, and the surface of the pull plates is provided with anti-slip particles.

[0010] Furthermore, this application also proposes that the surface of the rotating plate is provided with anti-slip threads, and the number of anti-slip threads is not less than fifteen.

[0012] As can be seen from the above, the tool processing oil immersion device and its feeding and filtering components provided in this application effectively remove impurities such as metal shavings by circulating and filtering the oil through the filter screen and conveying pump in the filtering component. At the same time, the feeding component realizes the automated delivery and fixation of the tool, which solves the problems of oil pollution, uneven oil immersion and low operating efficiency in the traditional oil immersion process. It has the advantages of improving oil cleanliness, extending oil service life, improving oil immersion uniformity and operation convenience. Attached Figure Description

[0020] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0021] Please see Figure 1-5 In existing technologies, rust prevention treatment of cutting tools in the machining field typically involves manual oil immersion. Operators directly immerse the tools in open oil drums or pans, and during repeated handling, metal shavings and other impurities carried by the tools mix into the oil, causing contamination. This not only reduces the rust-preventive effect but also forces companies to frequently change the oil, increasing production costs. For example, in workshop environments where tools are processed in large quantities, open oil tanks cannot effectively block impurities, significantly shortening the oil's lifespan.

[0022] To address the aforementioned problems, the inventors discovered two key shortcomings in the traditional oil immersion process: firstly, manual operation makes it difficult to avoid impurities contaminating the oil; and secondly, it lacks a circulation and filtration mechanism. Through research into the oil contamination pathways, they found that metal debris primarily originates from residues on the tool surface. Based on this, they proposed adding a filtration structure to the oil immersion system to intercept impurities, while simultaneously designing a closed-loop oil circulation system. Further analysis revealed that the filtration structure needs to be removable and maintainable to allow for periodic cleaning of accumulated impurities.

[0023] Therefore, this application proposes an oil immersion device for tool processing, including an oil immersion tank 1. A feeding assembly 2 is provided at the top of the oil immersion tank 1, and a filter assembly 3 is provided on the left side of the inner cavity of the oil immersion tank 1. The filter assembly 3 includes a filter box 301 fixedly connected to the inner cavity of the oil immersion tank 1. A filter screen 304 is installed on the right side of the inner cavity of the filter box 301. Locking blocks 307 are provided at both ends of the filter screen 304. Slots 306 that mate with the locking blocks 307 are opened at both ends of the right side of the inner cavity of the filter box 301. Screw sleeves 3010 are provided at both ends of the top of the filter box 301. A screw rod 309 is threadedly connected to the inner cavity of the screw sleeve 3010. A rotating plate 3011 is provided on the left side of the screw rod 309, and a limiting block 302 is connected to the right side via a movable shaft 308. A guide block 3012 is provided at the bottom of the limiting block 302. Guide grooves 305 that mate with the guide blocks 3012 are opened at both ends of the top of the filter box 301. The limiting block 302 is located at the top of the slots 306 and the locking blocks 307. A delivery pump 4 is installed on the left side of the oil immersion tank 1. The input end of the delivery pump 4 is connected to the bottom left side of the oil immersion tank 1, and the output end is located above the filter box 301. A drain outlet 6 is provided on the front of the oil immersion tank 1.

[0024] The filter box 301 refers to the box structure used to house the filter screen 304, which can be made of stainless steel welded box. The filter screen 304 is set on the right side to intercept metal debris in the oil. The cooperation between the locking block 307 and the locking groove 306 refers to the interlocking structure of the protrusion and groove, such as the trapezoidal cross-section design, to enable the filter screen 304 to be quickly positioned and installed. The threaded connection between the screw sleeve 3010 and the screw 309 means that the limit block 302 is moved by rotating the screw 309, for example, by using the M8 standard thread to achieve axial displacement adjustment. The cooperation between the guide block 3012 and the guide groove 305 means that the movement trajectory of the limit block 302 is restricted by the sliding pair, for example, by using the dovetail groove structure to ensure the vertical lifting and lowering of the limit block 302. The transfer pump 4 refers to the device used to draw oil to form a circulation, for example, a centrifugal pump is used to transport the oil at the bottom of the immersion tank 1 to the top of the filter box 301.

[0025] Specifically, the oil is drawn from the bottom of the immersion tank 1 by the transfer pump 4 and transported through pipelines to the top of the filter box 301. As the oil flows downwards through the filter screen 304, metal debris is intercepted in the right-side area of ​​the filter box 301. The filtered clean oil returns to the immersion tank 1, forming a closed loop. When the filter screen 304 needs to be replaced, rotating the rotating plate 3011 drives the screw 309 to disengage from the screw sleeve 3010, and the limiting block 302 moves upward along the guide groove 305 to release the clamping block 307, allowing the filter screen 304 to be pulled out of the slot 306. The feeding assembly 2 immerses the cutting tool to be treated in the oil, completes the rust prevention treatment, and automatically lifts it up, avoiding the introduction of impurities by manual operation.

[0026] Compared to existing technologies, traditional oil immersion devices rely on manual operation and lack filtration capabilities, requiring complete replacement once the oil becomes contaminated. This application achieves continuous oil purification through a closed-loop oil circulation system and a detachable filter structure, significantly extending the oil's service life. Simultaneously, the quick-release design of the locking block 307 and the locking groove 306 simplifies the maintenance process of the filter screen 304, and the cooperation between the guide block 3012 and the guide groove 305 ensures the movement accuracy of the limit block 302, preventing seal failure due to misalignment.

[0027] Through the above technical solution, this application effectively prevents metal debris carried by the cutting tool from entering the oil circulation system, reducing the decline in rust prevention performance caused by oil contamination. The detachable structure of the filter screen 304 reduces maintenance difficulty, and the oil circulation driven by the delivery pump 4 avoids localized impurity deposition in the oil tank. This device reduces the frequency of oil changes and the intensity of manual intervention while ensuring oil immersion efficiency.

[0028] This application further proposes a feeding assembly 2 for an oil immersion device for tool processing, including a frame 201 sleeved at the center of the surface of the oil immersion tank 1, an electric push rod 203 set at the top of the frame 201, the output end of the electric push rod 203 passing through the inner cavity of the frame 201 and connected to a conveying plate 204, and at least six hanging holes 205 equally spaced in the inner cavity of the conveying plate 204, the two sides of the electric push rod 203 being connected to the frame 201 through a fixing bracket 202, and fixing bolts 206 sleeved in the inner cavities at both ends of the frame 201 and threadedly connected to the oil immersion tank 1.

[0029] The frame 201 is a rigid structure supporting the electric push rod 203 and the conveyor plate 204. It can be constructed using welded metal profiles or bolted assembly, and is fitted onto the outer wall of the immersion tank 1 to form a stable connection. The electric push rod 203 is the power element that drives the conveyor plate 204 to move vertically. It can be implemented using a hydraulic cylinder or a servo motor with a lead screw structure, and its output end extension controls the depth of the cutter's immersion in the oil. The conveyor plate 204 is a flat plate structure that carries the cutter. It can be made of stamped steel plate or aluminum alloy plate, and its surface has hanging holes 205 for suspending cutters of different sizes. The fixing frame 202 is a support structure that enhances the connection strength between the electric push rod 203 and the frame 201. It can be implemented using welded angle steel or U-shaped clips to prevent vibration of the electric push rod 203 during operation from affecting positioning accuracy. The fixing bolt 206 is a detachable connector that secures the frame 201 to the immersion tank 1. It can be implemented using hexagonal head bolts with anti-loosening washers, facilitating quick disassembly and assembly during equipment maintenance.

[0030] Specifically, the frame 201 is rigidly connected to the oil immersion tank 1 by fixing bolts 206, and the electric push rod 203 is fixed to the center of the top of the frame 201 by the fixing bracket 202. When the electric push rod 203 is started, its output end drives the conveyor plate 204 to move vertically, and the cutters suspended in the hanging holes 205 are immersed in the oil or lifted above the liquid surface. The evenly spaced design of the hanging holes 205 allows multiple cutters to complete the oil immersion treatment simultaneously, and the combination structure of the fixing bracket 202 and the fixing bolts 206 ensures that all components remain stably aligned during equipment operation.

[0031] Compared to existing technologies, traditional manual operation requires individually picking up and immersing each tool in oil. This solution, however, uses an electric actuator 203 to drive a conveyor plate 204, achieving automated batch processing and avoiding direct contact between operators and the oil. In existing technologies, unstable tool suspension can lead to tilted immersion, while the equidistant hanging holes 205 design ensures uniform tool distribution and complete oil film coverage of the tool surface. Furthermore, existing equipment lacks an adjustable lifting mechanism; this solution uses the electric actuator 203 to precisely control the immersion time and depth, improving process consistency.

[0032] Through the above technical solutions, this application achieves mechanized operation of the tool immersion process, effectively reducing the probability of metal debris being introduced into the oil. The array layout of the hanging holes 205 allows multiple tools to undergo immersion simultaneously, significantly improving work efficiency. The mating structure between the fixing bolts 206 and the frame 201 facilitates quick disassembly and cleaning during equipment maintenance, preventing oil residue from causing component corrosion. The stroke control function of the electric push rod 203 ensures that tools of different sizes can be completely immersed, solving the problem of difficulty in controlling the immersion depth during manual operation.

[0033] This application further proposes that both sides of the electric push rod 203 are fixedly connected to the fixing frame 202, and the other end of the fixing frame 202 is fixedly connected to the frame 201.

[0034] Among them, the fixed frame 202 refers to the rigid connection structure used to support the electric push rod 203. Specifically, it can be realized by stamping metal sheet or welding frame 201 structure. Its function is to distribute the vibration load of the electric push rod 203 during operation through the fixed frames 202 arranged symmetrically on both sides.

[0035] Among them, the fixed connection refers to the rigid connection that cannot be disassembled. Specifically, it can be achieved by welding or an integrated casting structure. Its function is to ensure that the relative position between the electric push rod 203 and the frame 201 remains constant by eliminating the gaps in movement.

[0036] Specifically, during the operation of the feeding assembly 2 of the oil immersion device, the electric push rod 203 drives the conveyor plate 204 to perform vertical lifting and lowering actions, generating reciprocating inertial force. By symmetrically arranging fixed frames 202 on both sides of the electric push rod 203 and rigidly connecting the other end of the fixed frame 202 to the frame 201, a stable triangular support structure is formed. This structure can effectively suppress the lateral sway of the electric push rod 203 during high-speed lifting and lowering, avoiding loosening of connecting bolts or positioning deviations caused by vibration, thereby ensuring that the cutters mounted on the conveyor plate 204 are always immersed in the oil along the preset trajectory.

[0037] Compared with existing technologies, the electric actuator 203 of traditional oil-immersed devices is usually fixed only by a single point suspension or a simple bracket, which is prone to fatigue deformation of the support structure during long-term, high-frequency lifting operations. This solution, through the symmetrical support system formed by the double-sided fixing brackets 202, significantly enhances the installation rigidity of the electric actuator 203, reduces the probability of component wear caused by vibration, and reduces equipment maintenance downtime.

[0038] Through the above technical solution, this application achieves precise control of the running trajectory of the electric push rod 203, ensuring that the conveyor plate 204 does not shift horizontally during the oil immersion process and avoiding collision between the cutter and the inner wall of the oil immersion tank 1. The symmetrical arrangement of the fixed frame 202 on both sides further balances the force state of the electric push rod 203, extends the service life of the drive mechanism, and improves the continuity and stability of the oil immersion operation.

[0039] This application further proposes that the inner cavities at both ends of the frame 201 are fitted with fixing bolts 206, and the inner side of the fixing bolts 206 is threadedly connected to the oil immersion tank 1.

[0040] Among them, the fixing bolt 206 refers to a fastener with external threads, which can be a hexagonal head bolt or a flange bolt, used to form a detachable mechanical connection between the frame 201 and the oil immersion tank 1.

[0041] Among them, threaded connection refers to fixing by fitting bolts with pre-made threaded holes in the oil immersion tank 1. Specifically, standard metric threads or fine threads can be used, and the tightness can be adjusted by rotating the bolts.

[0042] Specifically, during the installation of frame 201, fixing bolts 206 pass through the inner cavities at both ends of frame 201 and are embedded in pre-drilled threaded holes in the side wall of the immersion tank 1 via threaded connections. When the bolts are rotated to the predetermined torque, frame 201 is pressed against the surface of immersion tank 1, preventing displacement of frame 201 due to vibration or load. When disassembly and maintenance are required, the bolts can be rotated in the opposite direction to release the constraint without damaging the structure.

[0043] Compared with existing technologies, the frame 201 of traditional oil immersion devices is mostly fixed by welding or gluing, which results in difficult disassembly and high maintenance costs. This solution achieves reversible fixing through threaded connection, which not only ensures installation stability but also facilitates quick assembly and disassembly of the frame 201, adapting to maintenance needs under different working conditions.

[0044] Through the above technical solution, this application solves the problem of irreversible rigid connection between frame 201 and immersion tank 1, reduces the difficulty of equipment maintenance, and avoids the risk of tool delivery deviation or oil leakage caused by loose frame 201.

[0045] This application further proposes that both ends of the top of the filter screen 304 are provided with pull plates 303, and the surface of the pull plates 303 is provided with anti-slip particles.

[0046] The pull plate 303 refers to the gripping structure located on the upper edge of the filter screen 304. It can be made by stamping or injection molding from a metal sheet, and its surface can have through holes or grooves to enhance grip stability. This structure provides a point of leverage for operators to grasp and disassemble the filter screen 304.

[0047] The anti-slip particles refer to the raised structures distributed on the surface of the pull plate 303. These can be achieved by molding rubber particles or bonding silicone particles, with particle diameters ranging from 1 to 3 millimeters. This structure increases the coefficient of friction on the contact surface to prevent slippage during operation.

[0048] Specifically, when cleaning or replacing the filter 304, the operator can apply upward force by holding the two pull plates 303 with both hands. The anti-slip particles generate friction against the palm to prevent slippage. The pull plates 303 are welded or bolted to the top of the filter 304, and their symmetrical distribution ensures even force distribution, preventing deformation of the filter 304 due to unilateral force application. The anti-slip particles are arranged in an array on the surface of the pull plates 303, for example, 4-6 particles per square centimeter, ensuring sufficient resistance in all directions when gripping.

[0049] Compared to existing technologies, traditional oil-immersing filter screens 304 often feature a flat edge design, requiring tools for disassembly and posing a risk of slippage. This solution, by adding a pull plate 303 with anti-slip particles, allows operators to disassemble the filter by hand without additional tools and effectively prevents the safety hazard caused by hand slippage.

[0050] Through the above technical solution, this application solves the problem of low maintenance efficiency caused by the difficulty in disassembling the filter screen 304. By providing a clear force application point through the pull plate 303 and using anti-slip particles to enhance grip stability, it ensures that the filter screen 304 can be quickly and safely removed for cleaning, thereby maintaining the cleanliness of the oil and extending the equipment maintenance cycle.

[0051] This application further proposes that the surface of the turntable 3011 is provided with anti-slip threads, and the number of anti-slip threads is not less than fifteen.

[0052] Among them, the anti-slip threads refer to the continuous raised texture formed on the surface of the rotating plate 3011. Specifically, it can be achieved by roll forming or cutting process. Its function is to increase the friction between the operator's hand and the contact surface of the rotating plate 3011.

[0053] The requirement of "not less than fifteen" refers to the lower limit of the number of threads evenly distributed along the circumferential edge of the rotating plate 3011. Specifically, the threads can be arranged by dividing the circumferential angle equally. Its function is to ensure that the rotating plate 3011 is subjected to uniform force and has a stable anti-slip effect during rotation.

[0054] Specifically, during the operation of the oil immersion device, when the filter screen 304 needs to be removed for maintenance, the operator must manually rotate the rotating plate 3011 to release the locking effect of the screw 309 on the limiting block 302. The anti-slip threads on the surface of the rotating plate 3011 increase the coefficient of friction of the contact surface, allowing the operator to hold the rotating plate 3011 firmly even in oily environments. More than fifteen threads are evenly distributed along the outer edge of the rotating plate 3011, forming a continuous anti-slip contact area to prevent the screw 309 from being unable to be effectively unscrewed due to hand slippage.

[0055] Compared with existing technologies, the rotating plate 3011 of traditional oil immersion devices is mostly a smooth surface, which is prone to hand slippage in the oil immersion environment, making maintenance and operation difficult. This solution achieves reliable rotation of the screw 309 without the need for additional tools by setting a specific number of anti-slip threads on the surface of the rotating plate 3011.

[0056] Through the above technical solution, this application effectively solves the technical problem of easy slippage during operation of the 3011 rotating plate in an oily environment, reduces the risk of low maintenance efficiency caused by hand slippage, and avoids the structural complexity caused by adding additional components such as anti-slip sleeves.

[0057] This application further proposes that the bottom of the oil immersion tank 1 is provided with an anti-slip pad 5, and the bottom of the anti-slip pad 5 is provided with anti-slip particles.

[0058] The anti-slip mat 5 refers to an elastic pad attached to the bottom of the oil immersion tank 1 to increase the friction of the contact surface. It can be made of rubber or silicone. The reaction force generated by the elastic deformation of the material counteracts equipment vibration or external impact. The anti-slip particles refer to the raised structures distributed on the bottom surface of the anti-slip mat 5. They can be made of regularly arranged hemispherical bumps or staggered stripes. They increase the frictional resistance with the supporting surface by increasing the roughness of the contact surface.

[0059] Specifically, during the operation of the oil immersion device, the oil immersion tank 1 may shift due to internal liquid sloshing or external equipment vibration. The anti-slip mat 5 absorbs vibration energy through its own elastic deformation, and at the same time, the anti-slip particles form multi-point interlocking when in contact with the ground, increasing static friction. When the equipment is subjected to a horizontal external force, the geometric structure of the anti-slip particles generates a mechanical locking effect, preventing the oil immersion tank 1 from sliding, thereby maintaining the overall stability of the equipment and avoiding the risk of oil splashing or tipping due to displacement.

[0060] Compared to existing technologies, traditional oil immersion devices typically place the tank directly on the ground, which can easily lead to slippage during oil circulation or workpiece handling. This solution achieves self-stabilization of the equipment through the synergistic effect of anti-slip pads 5 and anti-slip particles, eliminating the need for additional fixing devices. This simplifies the installation process and avoids oil contamination or equipment collisions caused by tank slippage.

[0061] Through the above technical solution, this application effectively prevents the oil immersion device from moving unexpectedly during operation, ensures the stability of the tool oil immersion process, avoids oil leakage or spillage accidents caused by equipment displacement, and improves operational safety and processing efficiency.

[0062] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
