Description

Technical Field

[0001] This invention relates to the field of wire EDM machine tool accessories technology, and in particular to a filter anti-loosening installation mechanism adapted to various models of wire EDM machines. Background Technology

[0002] Wire EDM machines are core equipment for precision mold and metal parts processing. They achieve high-precision contour cutting based on the principle of electrical discharge erosion, ensuring workpiece dimensional accuracy and surface finish. They are suitable for precision manufacturing scenarios such as molds, hardware, and electronics, improving processing efficiency and finished product consistency. They are key equipment for achieving automated and refined production in precision machining.

[0003] The filter is an accessory for wire EDM machine tools. It is usually installed on the filter box. After the coolant is delivered to the filter, it is temporarily stored in the filter box and then delivered to the machine tool. The filter is responsible for filtering metal debris and electrolytic impurities in the working fluid, maintaining the cleanliness of the coolant, ensuring the stability of EDM and the cutting accuracy, extending the life of the machine tool and consumables, reducing maintenance costs, and providing key support for the continuous, efficient, stable and reliable operation of the wire EDM machine tool. It is an important part of precision machining quality control.

[0004] In the existing technology, the filter input end is connected to the infusion pipe, and the filter is placed directly on the filter box without the need for a fixed structure. This has obvious drawbacks. The filter is easily loosened and displaced due to vibration or pipe pulling. Moreover, the filtered water only accumulates in the filter box, which not only requires a water pump to transport it to the machine tool, but also poses a risk of secondary contamination of the coolant in the filter box. Summary of the Invention

[0005] The purpose of this invention is to provide a filter anti-loosening installation mechanism that is compatible with various models of wire EDM machines, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water tank is included, the water tank being mounted on an online cutting machine tool; a protective cylinder is also included, the protective cylinder being mounted on the water tank; a top fixing member is provided at the top of the protective cylinder; a bottom fixing member is provided at the bottom of the protective cylinder; an elastic member is provided between the protective cylinder and the bottom fixing member; a drainage component is provided at the bottom of the bottom fixing member; multiple sets of top fixing members are provided; the top fixing members are mounted on the protective cylinder via fixing rings; each top fixing member includes a connecting plate, a limiting plate, and a baffle; the connecting plate is mounted on the fixing ring; the limiting plate is rotatably connected to the connecting plate; the baffle is mounted on the fixing ring; and the bottom end of the limiting plate near the fixing ring contacts the top surface of the baffle.

[0007] Preferably, the water tank includes a tank body and a fixing plate, the tank body is fixed on a wire cutting machine, and the fixing plate is fixed on the top of the tank body.

[0008] With the above solution, the housing is welded to the wire EDM machine, and the fixing plate is welded to the housing. The wire EDM machine provides the mounting base for the housing and the fixing plate, while the fixing plate serves as the fixing base for the protective cylinder.

[0009] Preferably, the protective cylinder includes a cylinder body, a slide rail is fixed to the bottom of the cylinder body, symmetrically arranged clamping plates are slidably connected to the bottom of the slide rail, an adjusting screw is threaded to the bottom of the clamping plate, and a top plate is rotatably connected to the adjusting screw.

[0010] With the above scheme, the slide rail and the cylinder are fixedly connected, the clamping plate and the slide rail are slidably connected, the adjusting screw and the clamping plate are threadedly driven, and the top plate and the adjusting screw are rotatably connected. The protective cylinder constitutes the protective and clamping structure of the filter, the cylinder provides a space for the filter, the clamping plate can slide along the slide rail to adjust the spacing, and rotating the adjusting screw can drive the top plate to move laterally, thereby clamping the outer side of the cylinder. This scheme adapts to the installation requirements of cylinders of different specifications, improves the overall stability of the protective cylinder, and prevents the protective cylinder from loosening and shifting due to machine tool vibration.

[0011] Preferably, the top of the cylinder has a pre-set mounting hole, and the fixing ring is fixed to the cylinder by bolts and the mounting hole.

[0012] Through the above scheme, the fixing ring and the cylinder are connected in a detachable rigid manner by bolts and mounting holes. The mounting holes provide precise annular installation positioning for the fixing ring. The fixing ring serves as the mounting carrier for the top fixing components, allowing multiple sets of top fixing components to be evenly distributed in an annular shape. This ensures that the top fixing components exert a uniform fixing force on the top of the filter, avoiding localized damage to the filter. At the same time, the bolt connection facilitates disassembly and maintenance, and the installation position of the top fixing components can be adjusted according to the filter specifications to meet the fixing requirements of multiple filter models.

[0013] Preferably, the bottom fixing component includes a bucket body, the top of which has a stepped circular groove, and the bucket body is slidably mounted on the protective cylinder.

[0014] With the above scheme, the hopper and the protective cylinder are vertically slidingly fitted. The stepped circular groove is a groove-type limiting structure at the top of the hopper. The bottom fixing component serves as the bottom support of the filter and the clean liquid collection structure. The hopper supports the bottom of the filter and provides axial support. The stepped circular groove radially limits the bottom of the filter to prevent it from rotating circumferentially. The hopper can slide up and down along the protective cylinder to adapt to filters of different heights. With the elastic force of the elastic component, the filter is tightened, achieving adaptive bottom fixing for filters of different sizes.

[0015] Preferably, the bottom fixing component further includes a sliding groove and a sliding strip. The sliding groove is formed on the bucket body, and the sliding strip is fixed inside the cylinder. The bucket body slides with the cylinder body through the cooperation of the sliding strip and the sliding groove.

[0016] With the above solution, the slide bar and the cylinder are fixedly connected, and the slide groove and the slide bar are slidably engaged. The two constitute the vertical guide structure of the bucket, which restricts the bucket to slide only up and down along the cylinder, preventing circumferential displacement during sliding and ensuring that the stepped circular groove is always precisely aligned with the bottom of the filter. At the same time, the guide structure makes the sliding of the bucket smoother, so that the elastic force of the elastic element can be evenly transmitted to the bottom of the filter, ensuring the filter is under balanced force, improving the overall fixing effect, and avoiding local stress that could damage the filter.

[0017] Preferably, the draining component includes an output pipe and a connector, the output pipe being connected to the bottom of the hopper body, and the connector being installed at the bottom of the output pipe.

[0018] With the above solution, the output pipe and the bucket body are integrated into a single connected structure, the connector and the output pipe are fixedly installed and connected, the drain component serves as the output structure for the filtered clean liquid, the clean liquid collected in the bucket body is guided and transported through the output pipe, and the connector serves as the connection end with the machine tool coolant pipe, providing a standardized connection interface, so that the clean liquid can be directly transported from the bucket body to the machine tool without the need for an additional water pump. The integrated connected structure avoids clean liquid residue, and the standardized interface ensures the connection is sealed, preventing coolant leakage and secondary pollution.

[0019] The technical effects and advantages of this invention are as follows: 1. In this invention, the filter is placed inside the cylinder. The bottom of the filter will rotate against the moving limiting plate until the filter moves to the bottom of the limiting plate. During the downward movement of the filter, it will squeeze the elastic element. The elastic force generated by the elastic element can push the filter upward. The limiting plate will be fastened to the top of the filter. The limiting plate is set at an angle, thus forming a conical fit on the top of the filter. The stepped circular groove can limit the bottom of the filter, thereby enabling the device to fix filters of different sizes axially and radially.

[0020] 2. This invention can collect the filtered liquid through the hopper and export it through the stepped circular groove. The stepped circular groove can be connected to the coolant input pipe of the machine tool, so that the filtered coolant can be directly delivered to the machine tool without the need for an additional water pump and is not easily contaminated.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] This invention provides, for example Figures 1 to 7 The filter anti-loosening mounting mechanism shown is compatible with multiple models of wire EDM machines. It includes a water tank 1, which includes a housing 101 and a fixing plate 102. The housing 101 is fixed on the wire EDM machine 2, and the fixing plate 102 is fixed on the top of the housing 101. The housing 101 is welded to the wire EDM machine 2, and the fixing plate 102 is welded to the housing 101. The wire EDM machine 2 provides a mounting base for the housing 101 and the fixing plate 102, and the fixing plate 102 serves as a fixing base for the protective cylinder 3.

[0025] Water tank 1 is installed on wire cutting machine tool 2. The top of the protective cylinder 3 is provided with a top fixing part 4. Multiple sets of top fixing parts 4 are provided. The top fixing parts 4 are installed on the protective cylinder 3 through fixing rings. The top fixing part 4 includes a connecting plate 401, a limiting plate 402, and a baffle 403. The connecting plate 401 is set on the fixing ring. The limiting plate 402 is rotatably connected to the connecting plate 401. The baffle 403 is set on the fixing ring. The bottom end of the limiting plate 402 near the fixing ring is in contact with the top surface of the baffle 403.

[0026] It also includes a protective cylinder 3, which is installed on the water tank 1. The protective cylinder 3 includes a cylinder body 301, a slide rail 305 fixed to the bottom of the cylinder body 301, and symmetrically arranged clamping plates 302 slidably connected to the bottom of the slide rail 305. An adjusting screw 304 is threadedly connected to the bottom of the clamping plate 302, and a top plate 303 is rotatably connected to the adjusting screw 304. The slide rail 305 is fixedly connected to the cylinder body 301, and the clamping plates 302 are slidably engaged with the slide rail 305. The adjusting screw 304 and the clamping plate 302 are also slidably engaged. The protective cylinder 3 is driven by a thread, with the top plate 303 and the adjusting screw 304 rotating together. The protective cylinder 3 forms the protective and clamping structure of the filter. The cylinder 301 provides space for the filter. The clamping plate 302 can slide along the slide rail 305 to adjust the spacing. Rotating the adjusting screw 304 can drive the top plate 303 to move laterally, thereby clamping the outer side of the cylinder 301. This adapts to the installation requirements of cylinders 301 of different specifications, improves the overall stability of the protective cylinder 3, and prevents the protective cylinder 3 from loosening and shifting due to machine tool vibration.

[0027] The top of the cylinder 301 has a pre-set mounting hole. The fixing ring is fixed to the cylinder 301 by bolts and mounting holes. The fixing ring and the cylinder 301 form a detachable rigid connection through bolts and mounting holes. The mounting hole provides a precise annular mounting position for the fixing ring. The fixing ring serves as the mounting carrier for the top fixing component 4, allowing multiple sets of top fixing components 4 to be evenly distributed in an annular shape. This ensures that the fixing force of the top fixing component 4 on the top of the filter is uniform, avoiding localized damage to the filter. At the same time, the bolt connection facilitates disassembly and maintenance. The installation position of the top fixing component 4 can be adjusted according to the filter specifications to meet the fixing requirements of multiple filter models.

[0028] The bottom of the protective cylinder 3 is provided with a bottom fixing member 5. An elastic member, which is a compression spring, is provided between the protective cylinder 3 and the bottom fixing member 5. The bottom fixing member 5 includes a bucket body 501. A stepped circular groove 502 is opened on the top of the bucket body 501. The bucket body 501 is slidably mounted on the protective cylinder 3. The bucket body 501 and the protective cylinder 3 are vertically slidingly engaged. The stepped circular groove 502 is a groove-type limiting structure on the top of the bucket body 501. The bottom fixing member 5 serves as the bottom support of the filter and the clean liquid collection structure. The bucket body 501 receives the bottom of the filter and provides axial support. The stepped circular groove 502 radially limits the bottom of the filter to prevent it from rotating circumferentially. The bucket body 501 can slide up and down along the protective cylinder 3 to adapt to filters of different heights. With the elastic force of the elastic member, the filter is tightened, realizing adaptive bottom fixing for filters of different sizes.

[0029] The bottom fixing component 5 also includes a sliding groove 503 and a sliding strip 504. The sliding groove 503 is formed on the bucket body 501, and the sliding strip 504 is fixed to the inner side of the cylinder 301. The bucket body 501 slides with the cylinder 301 through the cooperation of the sliding strip 504 and the sliding groove 503. The sliding strip 504 is fixedly connected to the cylinder 301, and the sliding groove 503 and the sliding strip 504 are in sliding cooperation. The two constitute the vertical guide structure of the bucket body 501, which restricts the bucket body 501 to slide only up and down along the cylinder 301, preventing circumferential displacement during sliding, ensuring that the stepped circular groove 502 is always accurately aligned with the bottom of the filter. At the same time, the guide structure makes the sliding of the bucket body 501 more stable, so that the elastic force of the elastic element can be evenly transmitted to the bottom of the filter, ensuring the filter is under balanced force, improving the overall fixing effect, and avoiding local stress that could damage the filter.

[0030] The bottom of the bottom fixing component 5 is provided with a drainage component 6, which includes an output pipe 601 and a connector 602. The output pipe 601 is connected to the bottom of the hopper 501, and the connector 602 is installed at the bottom of the output pipe 601. The output pipe 601 and the hopper 501 are an integral connected structure, and the connector 602 and the output pipe 601 are fixedly connected. The drainage component 6 serves as the output structure for filtered clean liquid. The clean liquid collected in the hopper 501 is guided and transported through the output pipe 601. The connector 602 serves as the connection end with the machine tool coolant pipe, providing a standardized connection interface to realize the direct delivery of clean liquid from the hopper 501 to the machine tool without the need for an additional water pump. The integrated connected structure avoids clean liquid residue, and the standardized interface ensures connection sealing and prevents coolant leakage and secondary pollution.

[0031] Working principle: After the filter is placed inside the cylinder 301, its bottom will push the limiting plate 402 to rotate until the entire filter moves down to the position below the limiting plate 402. During the downward movement of the filter, it will simultaneously squeeze the elastic element at the bottom of the bucket 501, causing the elastic element to undergo elastic deformation. With the elastic force formed by the reset of the elastic element, the bucket 501 and the filter can be pressed upward. The stepped circular groove 502 on the bucket 501 can limit the bottom of the filter. At this time, the limiting plate 402 will be fastened to the top of the filter, and the limiting plate 402 is set at an angle to form a conical fit with the top of the filter. At the same time, the stepped circular groove 502 can limit the bottom of the filter, thereby completing the dual axial and radial fixation of filters of different sizes and specifications.

[0032] The clean coolant filtered by the filter is collected in the hopper 501 and then smoothly discharged through the output pipe 601 and connector 602. The connector 602 can be directly connected to the coolant input pipe of the wire cutting machine tool 2 to realize the direct delivery of the filtered coolant to the machine tool without the need for an additional water pump to assist in the delivery. At the same time, it can effectively avoid the problem of secondary pollution of coolant in the transfer and storage stage, and continuously ensure the cleanliness of the coolant.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
