Description

Technical Field

[0001] This invention relates to the field of maintenance tool storage technology, specifically to a device for storing CNC machine tool maintenance tools, and particularly a multi-functional integrated device for storing CNC machine tool maintenance tools. Background Technology

[0002] CNC machine tools are equipment used to process parts. During use, they may require repair due to damage to parts, thus necessitating the use of corresponding tool storage devices. Existing tool storage devices have limited functionality, typically only enabling the storage and movement of tools.

[0003] In actual maintenance, some workpieces that are difficult to repair directly on the machine tool, such as motors and spindles, need to be disassembled and placed on a special platform for inspection. Meanwhile, CNC machine tools generate a large amount of metal shavings during milling and turning. These shavings easily mix with machine oil and adhere to the surface of parts. If not cleaned in time, they will interfere with maintenance operations. Therefore, maintenance personnel usually need to move the workpieces to an open or designated area for cleaning to avoid contaminating the workshop floor or causing splashes that corrode surrounding equipment. This process is time-consuming and labor-intensive, and repeated handling increases the risk of workpiece damage. Furthermore, for items that cannot be repaired on-site, appropriate transfer equipment is required, which is quite troublesome.

[0004] Therefore, the research objective of this invention is to design a CNC machine tool maintenance tool storage device that has a highly adaptable and adjustable storage space for the safe temporary storage of disassembled basic workpieces; and that can isolate and clean workpieces during equipment maintenance by adding a simple cleaning mechanism to facilitate the smooth progress of the maintenance process; and that can provide protective handling for workpieces that need to be moved. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a CNC machine tool maintenance tool storage device, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is: A device for storing CNC machine tool maintenance tools, comprising: A mobile vehicle body, on which a closed cabinet with a door is installed; The ring-shaped fixing frame and the extended support plate can be pulled out and stored separately and are spaced apart inside the closed cabinet. An adjustable placement mechanism includes a flexible tubular membrane fixedly mounted at its bottom end on the extended support plate, and an annular movable frame fixedly provided at the top end of the flexible tubular membrane. The flexible tubular membrane can be extended and retracted up and down by moving the annular movable frame up and down. The connecting mechanism, when the flexible tubular membrane is stretched upward into place, is used to detachably and fix the annular movable frame and the annular fixed frame, so that the extended support plate and the flexible tubular membrane form an isolation container for cleaning the workpiece to be repaired; The covering and fixing mechanism is used to detachably and fix the annular moving frame and the outer support plate when the annular moving frame is rotated axially to make the middle part of the flexible tubular membrane rotate and the isolation container form a closed shape, and gradually shrinks until the flexible tubular membrane tightly covers the outside of the workpiece to be repaired. A collection container, mounted on the extended support plate, is used to collect the cleaning fluid inside the isolation container.

[0007] It also includes a cleaning mechanism, which comprises a water tank installed inside the enclosed cabinet and a water pump connected to the water tank. The outlet of the water pump is equipped with a high-pressure nozzle via a corresponding extension hose.

[0008] The extended support plate is recessed at the location where the adjustable placement mechanism is set to form a corresponding receiving groove. The liquid collection container is set in the hollow part on the outer side of the extended support plate. A through hole is provided between the receiving groove and the liquid collection container. The extended support plate is provided with a drain port that connects to the liquid collection container. An on / off valve is installed on the drain port.

[0009] The receiving groove is formed by two annular tubes fixedly fitted inside and outside to form an annular groove for installing the flexible tubular membrane. The bottom end of the flexible tubular membrane is fixed in the annular groove by adhesive and further fixed by rivets. When the flexible tubular membrane is stored, it is compressed into the annular groove in a pleated shape.

[0010] The connecting mechanism includes a first magnet and a second magnet, which are respectively fixed to the lower end face of the annular fixed frame and the upper end face of the annular movable frame. The first magnet and the second magnet have opposite poles. After the flexible tubular membrane is stretched into place, it is fixed by the attraction between the opposite poles of the first magnet and the second magnet.

[0011] The covering and fixing mechanism includes a third magnet and a fourth magnet respectively fixed to the lower end face of the annular moving frame and the upper end face of any of the annular tubes. The third magnet and the fourth magnet are opposite poles and their magnetic attraction force is greater than the rebound force of the flexible tubular membrane after it is tightened. After the flexible tubular membrane is tightened or compressed into place, it is fixed by the attraction of the opposite poles of the third magnet and the fourth magnet.

[0012] The outer end of the extended support plate protrudes from the closed cabinet, and both the protruding part and the bottom of the mobile vehicle are equipped with corresponding casters.

[0013] A corresponding limiting mechanism is provided between the extended support plate and the closed cabinet, which is used to detachably and fix the extended support plate and the closed cabinet when the extended support plate is stored in the position; the limiting mechanism includes a nut seat fixedly installed on the outer side wall of the closed cabinet, and a screw screwed to the nut seat; the top of the protruding part of the extended support plate is recessed with a positioning hole, and when the screw screw is rotated downward and its lower end is inserted into the positioning hole, the extended support plate and the closed cabinet are fixedly connected.

[0014] Both sides of the annular fixing frame and the extended support plate are limited and pulled out by the closed cabinet through corresponding sliding tracks.

[0015] The enclosed cabinet contains a tool placement area located above the cleaning mechanism, and at least one pull-out drawer is provided in the tool placement area.

[0016] Advantages of this invention: 1) This invention, through the same flexible tubular membrane combined with a retractable extended support plate and annular fixing frame, realizes the switching between three working states: isolation cleaning container, adaptive workpiece wrapping protection, and storage compression. This significantly expands the functionality of the maintenance tool storage device and solves the problem of the single function of existing devices. It not only has highly adaptable and adjustable storage space to safely store disassembled basic workpieces, but also can be combined with an added simple cleaning mechanism to conveniently isolate and clean the parts that need cleaning during the equipment maintenance process, so as to facilitate a smoother maintenance process. Furthermore, for workpieces that need to be transferred for maintenance, adaptive wrapping protection can be applied before handling, without rigid clamping damage, effectively avoiding shaking and bumping during transportation.

[0017] 2) This invention features a retractable extended support plate at the bottom of the mobile vehicle body. The retracted extended support plate provides a temporary storage platform for the workpiece. On this basis, a matching adjustable placement mechanism is added. The flexibility of the flexible tubular membrane allows for vertical expansion and contraction. When stretched upwards, it works in conjunction with the extended support plate to form a widened isolation space. Then, through the intervention of the built-in cleaning mechanism, the workpiece can be conveniently isolated and cleaned, effectively preventing the cleaning fluid from contaminating the workshop or corroding the equipment. After cleaning, the flexible tubular membrane is compressed downwards to expose the workpiece for easy maintenance by maintenance personnel. The operation is smooth and the space utilization rate is high.

[0018] 3) Based on the flexible tubular membrane providing an isolation space for cleaning, the present invention fixes an annular moving frame at its outer end. This not only facilitates the stretching of the flexible tubular membrane, but also, by rotating the annular moving frame, drives the middle part of the flexible tubular membrane to rotate and close, so that the isolation container forms a closed shape and gradually shrinks to tightly cover the outside of the workpiece to be repaired. This achieves buffered fixation and protective transportation of the workpiece, avoiding mechanical wear from rigid fixation and improving its practical effect. The added cleaning mechanism not only facilitates the cleaning and inspection of the workpiece, but also removes iron filings adhering to the workpiece, so as to prevent the iron filings from piercing the flexible tubular membrane covering the workpiece and causing it to lose its isolation space effect.

[0019] 4) The present invention uses a connecting mechanism and a covering and fixing mechanism to conveniently fix the flexible tubular membrane that is stretched upward, compressed downward, or rotated and closed. The use of opposite-polar magnets to attract each other can quickly fix the membrane in the stretched state and the covered state respectively. The operation is convenient, and the magnetic attraction force used by the covering and fixing mechanism is greater than the rebound force after the membrane is tightened, which can effectively prevent the membrane from automatically rotating and loosening, thus improving the reliability of use.

[0020] 5) Based on the setting of the extended support plate, the present invention uses the receiving groove for sinking isolation to prevent the cleaning fluid from leaking out from the connection gap of the flexible tubular membrane. Furthermore, a liquid collection container connected to the receiving groove is set on the convex part, which can discharge and store the cleaning fluid in a timely manner, avoiding pollution of the workshop and equipment by the cleaning fluid, and further improving the safety of on-site cleaning.

[0021] 6) The present invention has a corresponding limiting mechanism between the extended support plate and the closed cabinet. By rotating the screw downward and inserting its lower end into the positioning hole, the extended support plate and the closed cabinet can be quickly and conveniently locked. In addition, the extended support plate and the closed cabinet are equipped with universal wheels at the bottom for synchronous movement. When the extended support plate is pulled out for use, the screw only needs to be rotated upward until its lower end is disengaged from the positioning hole to achieve convenient unlocking. It is convenient for overall movement or individual pulling out for use. The operation is simple and the structure is stable. Attached Figure Description

[0030] To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-7 A device for storing CNC machine tool maintenance tools, comprising: Mobile vehicle body 1, on which a closed cabinet 10 with a cabinet door 9 is installed; The annular fixing frame 3 and the extended support plate 4 can be pulled out and stored, and are spaced apart inside the closed cabinet 10. The adjustable placement mechanism 5 includes a flexible tubular membrane 501 with its bottom end fixedly mounted on the extended support plate 4. The top end of the flexible tubular membrane 501 is fixedly provided with an annular moving frame 502. The flexible tubular membrane 501 can be moved up and down by moving the annular moving frame 502. The connecting mechanism 8 is used to detachably and fix the annular moving frame 502 and the annular fixed frame 3 when the flexible tubular membrane 501 is stretched upward into place, so that the extended support plate 4 and the flexible tubular membrane 501 form an isolation container for cleaning the workpiece to be repaired. The covering and fixing mechanism 6 is used to detachably and fix the annular moving frame 502 and the outer support plate 4 when the annular moving frame 502 is rotated axially to make the middle part of the flexible tubular membrane 501 rotate and close, and the isolation container forms a closed shape, and gradually shrinks until the flexible tubular membrane 501 tightly covers the outside of the workpiece to be repaired. The liquid collection container 7 is installed on the extended support plate 4 and is used to collect the cleaning liquid in the isolation container.

[0031] This invention, through the same flexible tubular membrane 501 in conjunction with a retractable extended support plate 4 and annular fixing frame 3, achieves switching between three working states: isolation cleaning container, adaptive workpiece wrapping and protection, and storage compression. This significantly expands the functionality of the maintenance tool storage device and solves the problem of the single function of existing devices. It not only has highly adaptable and adjustable storage space for the safe temporary storage of disassembled basic workpieces, but also can be combined with an added simple cleaning mechanism to conveniently isolate and clean the parts that need cleaning during the equipment maintenance process, so as to facilitate a smoother maintenance process. Furthermore, for workpieces that need to be transferred for maintenance, adaptive wrapping and protection can be applied before handling, without rigid clamping damage, effectively avoiding shaking and bumping during transportation.

[0032] The flexible tubular membrane 501 is preferably a commercially available oil-resistant, acid and alkali-resistant PVC coated cloth or polyurethane elastomer membrane with a thickness of 0.3~1.0mm and a radial elongation at break ≥200% to ensure that it does not break when tightened and can resist puncture by residual iron filings on the workpiece.

[0033] It also includes a cleaning mechanism 2, which includes a water tank 201 installed inside the enclosed cabinet 10 and a water pump 202 connected to the water tank 201. The outlet of the water pump 202 is equipped with a high-pressure nozzle 203 through a corresponding extension hose.

[0034] The extended support plate 4 is recessed at the location where the adjustable placement mechanism 5 is set to form a corresponding receiving groove 401. The liquid collection container 7 is set in the hollow part on the outer side of the extended support plate 4. A through hole is provided between the receiving groove 401 and the liquid collection container 7. The extended support plate 4 is provided with a drain port that connects to the liquid collection container 7. The drain port is equipped with an on / off valve 15.

[0035] Based on the extension support plate 4, the present invention uses the receiving groove 401 for sinking isolation to prevent the cleaning fluid from leaking out from the connection gap of the flexible tubular membrane 501. Furthermore, a liquid collection container 7 connected to the receiving groove 401 is provided on the convex part, which can discharge and store the cleaning fluid in a timely manner, avoiding pollution of the workshop and equipment by the cleaning fluid, and further improving the safety of on-site cleaning.

[0036] The receiving groove 401 is formed by two annular tubes 12 fixedly sleeved inside and outside to form an annular groove for installing the flexible tubular membrane 501. The bottom end of the flexible tubular membrane 501 is fixed in the annular groove by adhesive and further fixed by rivets. When the flexible tubular membrane 501 is stored, it is compressed into the annular groove in a pleated shape.

[0037] This invention features a retractable extended support plate 4 at the bottom of the mobile vehicle body 1. The retracted extended support plate 4 provides a temporary storage platform for the workpiece. On this basis, a matching adjustable placement mechanism 5 is added. The flexible tubular membrane 501 is used to extend and retract vertically. After being stretched upward, it works with the extended support plate 4 to form a widened isolation space. Then, with the intervention of the built-in cleaning mechanism 2, the workpiece is conveniently isolated and cleaned, effectively avoiding cleaning fluid contamination of the workshop or corrosion of equipment. After cleaning, the flexible tubular membrane 501 is compressed downward to expose the workpiece for maintenance personnel to inspect. The operation is smooth and the space utilization rate is high.

[0038] This invention, based on the provision of a flexible tubular membrane 501 to provide an isolation space for cleaning, fixes an annular moving frame 502 at its outer end. This not only facilitates the stretching of the flexible tubular membrane 501, but also, by rotating the annular moving frame 502, causes the middle part of the flexible tubular membrane 501 to rotate and close, so that the isolation container forms a closed shape and gradually shrinks until it tightly covers the outside of the workpiece to be repaired. This achieves buffered fixation and protective transportation of the workpiece, avoiding mechanical wear from rigid fixation and improving its practical effect. The added cleaning mechanism 2 not only facilitates the cleaning and maintenance of the workpiece, but also removes iron filings adhering to the workpiece, preventing the iron filings from puncturing the flexible tubular membrane 501 covering the workpiece and causing it to lose its isolation space effect.

[0039] The connecting mechanism 8 includes a first magnet 801 and a second magnet 802 respectively fixed to the lower end face of the annular fixed frame 3 and the upper end face of the annular movable frame 502. The first magnet 801 and the second magnet 802 are opposite poles. After the flexible tubular membrane 501 is stretched into place, the flexible tubular membrane 501 is fixed by the attraction of the opposite poles of the first magnet 801 and the second magnet 802.

[0040] The covering and fixing mechanism 6 includes a third magnet 601 and a fourth magnet 602 respectively fixed to the lower end face of the annular moving frame 502 and the upper end face of any of the annular tubes 12. The third magnet 601 and the fourth magnet 602 are opposite poles, and their magnetic attraction force is greater than the rebound force of the flexible tubular membrane 501 after it is tightened. After the flexible tubular membrane 501 is tightened or compressed and stored in place, the flexible tubular membrane 501 is fixed by the attraction of the opposite poles of the third magnet 601 and the fourth magnet 602.

[0041] The present invention uses a connecting mechanism 8 and a covering and fixing mechanism 6 to conveniently fix the flexible tubular membrane 501 that is stretched upward, compressed downward, or rotated and closed. The use of opposite-polar magnets to attract each other enables rapid fixing in both the stretched and covered states. The operation is convenient, and the magnetic attraction force used by the covering and fixing mechanism 6 is greater than the rebound force after the membrane is tightened, which can effectively prevent the membrane from automatically rotating and loosening, thus improving the reliability of use.

[0042] The outer end of the extended support plate 4 protrudes from the closed cabinet 10, and both the protruding part and the bottom of the mobile vehicle body 1 are provided with corresponding casters 16.

[0043] A corresponding limiting mechanism 13 is provided between the extended support plate 4 and the closed cabinet 10, which is used to detachably and fix the extended support plate 4 and the closed cabinet 10 when the extended support plate 4 is stored in the position; the limiting mechanism 13 includes a nut seat 1301 fixedly installed on the outer side wall of the closed cabinet 10, and a screw 1302 screwed to the nut seat 1301; the top of the protruding part of the extended support plate 4 is recessed with a positioning hole 402, and when the screw 1302 is rotated downward and its lower end is inserted into the positioning hole 402, the extended support plate 4 and the closed cabinet 10 are fixedly connected.

[0044] Both sides of the annular fixing frame 3 and the extended support plate 4 are limited and pulled out by the closed cabinet 10 through corresponding sliding rails 14.

[0045] The present invention provides a corresponding limiting mechanism 13 between the extended support plate 4 and the closed cabinet 10. By rotating the screw 1302 downward and inserting its lower end into the positioning hole 402, the extended support plate 4 and the closed cabinet 10 can be quickly and conveniently locked. In addition, the extended support plate 4 and the closed cabinet 10 are moved synchronously with the universal wheels provided below them. When the extended support plate 4 is pulled out for use, the screw 1302 only needs to be rotated upward until its lower end is disengaged from the positioning hole 402 to achieve convenient unlocking. It is convenient for overall movement or individual pulling out for use. The operation is simple and the structure is stable.

[0046] Inside the enclosed cabinet 10, above the cleaning mechanism 2, there is a tool placement area, and at least one drawer 11 can be pulled out of the tool placement area.

[0047] The enclosed cabinet 10 can also be equipped with a storage space between the outer support plate 4 and the cleaning mechanism 2. The cabinet door 9 is located on the side where the outer support plate 4 can be pulled out. When in use, the cabinet door 9 is opened, the outer support plate 4 is pulled out and the workpiece to be repaired is placed. After cleaning and protective fixing are completed, the outer support plate 4 and the workpiece to be repaired are pushed into the enclosed cabinet 10, the cabinet door 9 is closed and the workpiece to be repaired is transferred.

[0048] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.
