Description

Technical Field

[0001] This utility model belongs to the field of PMI foam board processing technology, and in particular relates to a PMI foam board processing fixing device. Background Technology

[0002] PMI foam board is a high-performance rigid closed-cell foam material, officially known as polymethacrylamide foam. It is foamed from a copolymer of methacrylic acid and methacrylonitrile, exhibiting a uniform closed-cell structure and high cross-linking degree. Due to its lightweight, high strength, high temperature resistance, and excellent dielectric properties, PMI foam board has become a core material in high-end fields such as aerospace, medical, transportation, and military industries.

[0003] In order to prevent the PMI foam board from shifting during the processing and affecting the processing quality, it is necessary to effectively fix the PMI foam board. There are many types of fixing devices on the market. For example, an aluminum plate cutting fixing device with publication number CN213136667U is disclosed on the China Patent Network. This fixing device can be used to fix the surface of the plate material, but there are some defects and shortcomings that need to be improved: (1) Most of the existing fixing devices fix the material by mechanical clamping. When the clamping force is not controlled properly, it is easy to cause wear or indentation on the surface of the PMI foam board. Although multiple clamping parts can be set to disperse the pressure, it is often difficult to accurately control the pressure applied by each clamping part during fixing, which causes the PMI foam board to deform due to uneven local force, thereby affecting the processing accuracy and the finished product qualification rate; (2) After the existing fixing devices complete the processing of PMI foam board, a large amount of waste will accumulate on their table, which needs to be cleaned in time. The traditional manual cleaning method is inefficient and labor-intensive. Although the waste can be cleaned quickly by automated cleaning equipment, the additional electrical equipment not only increases the operating and maintenance costs of the equipment, but also increases energy consumption, which is not conducive to energy conservation and environmental protection. Therefore, the PMI foam board processing and fixing equipment provided by this utility model is of great significance in addressing the above problems. Utility Model Content

[0004] This invention provides a PMI foam board processing and fixing device. It uses vacuum adsorption to firmly attach PMI foam boards to a fixing table, thus preventing displacement during processing. Compared to mechanical clamping, this effectively prevents damage to the PMI foam boards caused by improper clamping force. Multiple adsorption holes expand the vacuum adsorption range of the vacuum chamber, enhancing the adsorption and fixing effect. Simultaneously, the multiple adsorption holes fully cover the bottom surface of the PMI foam board, achieving multi-point adsorption and ensuring more even and sufficient adsorption force on the PMI foam board. Driving an electric telescopic rod allows the movable seat to move horizontally. As the movable seat moves, it moves the cleaning plate along with it. The cleaning brush sweeps residual debris from the processing table into various chip guide ports, which then guide the debris into a chip collection trough for unified recycling. This eliminates the need for additional electrical equipment, enabling automated debris cleaning. This significantly reduces operating and maintenance costs, effectively lowers energy consumption, and promotes energy conservation and environmental protection, thus solving the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Several adsorption holes are opened at the bottom of the positioning groove, and the adsorption holes communicate with the vacuum chamber. A dustproof plate is installed in the positioning groove, and a dustproof net is installed on the dustproof plate. A cleaning plate is installed at the bottom of the movable seat, and a cleaning brush is provided on the bottom surface of the cleaning plate.

[0008] Furthermore, guide seats are fixedly connected to both ends of the movable seat, and guide holes are provided on the guide seats.

The diameter of the guide rod is equal to the diameter of the guide hole, and each guide rod passes through the corresponding guide hole.

[0009] Furthermore, a pair of positioning rods are fixedly connected to the bottom of the fixed platform. The diameter of the positioning rods is equal to the diameter of the positioning holes, and the center of each positioning rod corresponds one-to-one with the center of each positioning hole.

[0010] Furthermore, both the dustproof plate and the positioning groove are rectangular, and the length, width, and thickness of the dustproof plate are equal to the length, width, and depth of the positioning groove, respectively. Each of the adsorption holes is distributed in a linear array along the length and width directions of the positioning groove.

[0011] Furthermore, a pair of extraction slots are provided on the top surface of the positioning slot, which are symmetrically distributed at both ends of the positioning slot and have a depth less than the depth of the positioning slot.

[0012] Furthermore, each of the two bottom sidewalls of the movable seat is fixedly connected with a locking block. The locking block is L-shaped and has a sliding groove on its inner side. The spacing between a pair of locking blocks is equal to the width of the cleaning plate. Each of the two sides of the cleaning plate is fixedly connected with a slider.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1-9 As shown, a PMI foam board processing and fixing device of the present invention includes a processing table 1, with support plates 2 fixedly connected to both sides of the bottom of the processing table 1, and brackets 3 fixedly connected to both sides of the top of the processing table 1. Each bracket 3 is equipped with a fixing component. Several chip guide ports 4 are opened on the surface of the processing table 1. Support plates 5 are fixedly connected between the support plates 2, and chip collection grooves 6 are placed on the support plates 5.

[0033] The fixed assembly includes an electric telescopic rod 7 and a movable seat 8. The movable seat 8 is U-shaped, with its top two sides protruding outwards and having positioning holes 9. A transmission block 10 is fixedly connected to the upper bottom surface of the movable seat 8. The electric telescopic rod 7 is mounted on the bracket 3, and its output shaft end is fixedly connected to the transmission block 10. A fixed platform 11 is mounted on the top of the movable seat 8, and an exhaust fan 12 is mounted on the upper bottom surface of the movable seat 8. An exhaust pipe 13 is mounted on the exhaust fan 12. A positioning groove 14 is opened on the top of the fixed platform 11, and a vacuum chamber 15 is opened inside the fixed platform 11. The other end of the exhaust pipe 13 is installed on the bottom of the fixed platform 11. The positioning groove 14 is connected to the vacuum chamber 15. Several adsorption holes 16 are provided at the bottom of the groove, and these holes 16 are connected to the vacuum chamber 15. When processing the PMI foam board, its two ends can be placed on two corresponding fixed platforms 11. The electric telescopic rod 7 can be driven to move the movable seat 8 along with the fixed platforms 11, adjusting the distance between the two fixed platforms 11 according to the length of the PMI foam board. Then, the exhaust fan 12 is driven to ventilate the vacuum chamber 15 through the exhaust pipe 13. Under negative pressure, the PMI foam board can be firmly adsorbed through the adsorption holes 16. Attached to the fixing table 11, it serves to fix the PMI foam board and prevent it from shifting during processing. Compared with mechanical clamping, this method effectively prevents damage to the PMI foam board due to improper clamping force. A dustproof plate 17 is installed in the positioning groove 14, and a dustproof net 18 is installed on the dustproof plate 17. When the dustproof plate 17 is installed in the positioning groove 14, it can adhere to the bottom of the PMI foam board. At the same time, the dustproof net 18 can cover each adsorption hole 16 to prevent dust. This effectively prevents dust and other impurities from accumulating and clogging the adsorption holes 16, thus affecting the adsorption of the PMI foam board. For a fixed effect, a cleaning plate 19 is installed at the bottom of the movable seat 8. A cleaning brush 20 is provided on the bottom surface of the cleaning plate 19. The bottom of the cleaning brush 20 is in contact with the surface of the processing table 1. When the movable seat 8 moves, it can drive the cleaning plate 19 to move together. At this time, the cleaning brush 20 can sweep the waste residue on the processing table 1 into each chip guide port 4, so that the waste can be guided into the chip collection tank 6 for unified recycling through the chip guide port 4. Thus, the automated cleaning of waste can be completed without configuring additional electrical equipment, which not only greatly reduces the operating and maintenance costs of the equipment, but also effectively reduces energy consumption, which is conducive to energy conservation and environmental protection.

[0034] The movable seat 8 has guide seats 21 fixedly connected to both ends of its outer wall. The guide seats 21 have guide holes 22. The top of the processing table 1 has two pairs of fixed blocks 23 fixedly connected. Each pair of fixed blocks 23 is fixedly connected to a guide rod 24. The diameter of the guide rod 24 is equal to the diameter of the guide hole 22. Each guide rod 24 passes through the corresponding guide hole 22. When adjusting the spacing of the fixed table 11, the cooperation between the guide rod 24 and the guide hole 22 can play a guiding and limiting role, so as to improve the stability of the movable seat 8 and prevent it from shaking and bumping during movement, which would affect the fixing effect of the PMI foam board.

[0035] The bottom of the fixed platform 11 is fixedly connected to a pair of positioning rods 25. The diameter of the positioning rods 25 corresponds to the diameter of the positioning holes 9, and the center of each positioning rod 25 corresponds to the center of each positioning hole 9. When the fixed platform 11 is placed on top of the movable seat 8, each positioning rod 25 can be aligned and pass through the corresponding positioning hole 9. At this time, the fixed platform 11 can be positioned by the mutual cooperation between the positioning rods 25 and the positioning holes 9 to prevent it from becoming loose. By pulling the positioning rods 25 out of the positioning holes 9, the fixed platform 11 and the exhaust fan 12 can be removed from the movable seat 8 for regular maintenance.

[0036] Both the dustproof plate 17 and the positioning groove 14 are rectangular, and the length, width, and thickness of the dustproof plate 17 correspond to the length, width, and depth of the positioning groove 14, respectively. The dustproof plate 17 can be inserted into and adhered to the inner wall of the positioning groove 14 to prevent the position of the dustproof plate 17 from shifting. Each adsorption hole 16 is linearly arrayed along the length and width of the positioning groove 14. The vacuum adsorption range of the vacuum chamber 15 can be expanded through multiple adsorption holes 16 to enhance the adsorption and fixation effect. At the same time, the bottom surface of the PMI foam board can be fully covered through multiple adsorption holes 16 to achieve a multi-point adsorption effect, thereby ensuring that the adsorption force on the PMI foam board is more sufficient and uniform.

[0037] The top surface of the positioning groove 14 is provided with a pair of take-out grooves 26, which are symmetrically distributed at both ends of the positioning groove 14. Their depth is less than the depth of the positioning groove 14. By inserting fingers into the two take-out grooves 26 and pinching the two ends of the dustproof plate 17, it can be quickly taken out of the positioning groove 14 so that the dustproof net 18 can be cleaned regularly.

[0038] The movable seat 8 has two bottom sidewalls fixedly connected with locking blocks 27. The locking blocks 27 are L-shaped and have grooves 28 on their inner sides. The spacing between a pair of locking blocks 27 is equal to the width of the cleaning plate 19. The cleaning plate 19 has two sides fixedly connected with sliders 29. Both sliders 29 and grooves 28 are rectangular. The thickness of sliders 29 is equal to the width of grooves 28. Sliders 29 can be inserted into and fit into the corresponding grooves 28 so that the cleaning plate 19 can be fixed to the bottom of the movable seat 8 by insertion. The cleaning plate 19 can slide along the locking blocks 27. When the sliders 29 slide out of the grooves 28, the cleaning plate 19 can be removed from the bottom of the movable seat 8 so that the cleaning brush 20 can be cleaned regularly.

[0039] The chip guide openings 4 are elongated and are equidistantly distributed along the length of the processing table 1. Each chip guide opening 4 is located directly above the chip collection groove 6. The top of the support plate 5 has several slots 30. The bottom of the chip collection groove 6 is fixedly connected to several inserts 31. The cross-sections of the inserts 31 and the slots 30 are circular, and their numbers and diameters are the same. The center of each insert 31 corresponds to the center of each slot 30. When the chip collection groove 6 is placed on the support plate 5, each insert 31 can be aligned and inserted into the corresponding slot 30. At this time, the chip collection groove 6 can be positioned by the cooperation between the inserts 31 and the slots 30 to ensure that the position of the chip collection groove 6 is directly below each chip guide opening 4. This can effectively prevent waste chips from falling into the chip collection groove 6 after falling through each chip guide opening 4.

[0040] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0041] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0042] The working principle of this utility model is as follows:

[0043] In use, the PMI foam board to be processed can be placed on two corresponding fixed platforms 11 at both ends. Driving the electric telescopic rod 7 moves the movable seat 8 along with the fixed platforms 11, allowing adjustment of the distance between the two fixed platforms 11 according to the length of the PMI foam board. Then, the exhaust fan 12 is driven to evacuate the vacuum chamber 15 through the exhaust pipe 13. Under negative pressure, the PMI foam board is firmly adsorbed onto the fixed platforms 11 through the various adsorption holes 16, thus preventing displacement during processing. Compared to mechanical clamping, this method effectively prevents damage to the PMI foam board due to improper clamping force. The multiple adsorption holes 16 expand the vacuum adsorption range of the vacuum chamber 15, enhancing the adsorption and fixation effect. Meanwhile, multiple adsorption holes 16 can fully cover the bottom surface of the PMI foam board to achieve a multi-point adsorption effect, thereby ensuring that the adsorption force on the PMI foam board is more sufficient and uniform. After the PMI foam board is fixed, it can be processed. After the equipment has been used for a long time, the electric telescopic rod 7 can be driven to move the movable seat 8 horizontally. When the movable seat 8 moves, it can move the cleaning plate 19 together. At this time, the cleaning brush 20 can sweep the waste residue on the processing table 1 into each chip guide port 4, so that the waste residue can be guided into the chip collection tank 6 for unified recycling through the chip guide port 4. Thus, the automated cleaning of waste residue can be completed without configuring additional electrical equipment, which not only greatly reduces the operating and maintenance costs of the equipment, but also effectively reduces energy consumption, which is conducive to energy conservation and environmental protection.
