Abstract

This utility model discloses a fixture structure for laser engraving carbon fiber mid-frames, including a base, a mounting seat at the top center of the base, and a mid-frame support mounted above the mounting seat. When laser engraving is required on the carbon fiber mid-frame, the mid-frame is placed on the mid-frame support of the appropriate size. A bidirectional hydraulic rod pushes the two racks apart, causing the racks to drive the two rotating arms to rotate simultaneously towards the mid-frame support. This rotation causes the pressure plates to press against both sides of the mid-frame, fixing it in place. The mid-frame support is detachably connected to the mounting seat via a quick-release mechanism, allowing for easy replacement of the mid-frame support according to its size. This fixture structure enables laser engraving on the mid-frame, quickly fixing it and preventing wobbling that could cause the engraving position to shift. Furthermore, the quickly replaceable mid-frame support allows for fixing mid-frames of different sizes.

Description

Technical Field

[0001] This utility model relates to the field of carbon fiber mid-frame technology, specifically a tooling structure for laser engraving of carbon fiber mid-frame. Background Technology

[0002] Carbon fiber has advantages such as high strength, long life, corrosion resistance, light weight, and low density. It is now commonly used in mechanical equipment such as model airplanes, lamp brackets, PC equipment shafts, etching machines, medical devices, sports equipment, and automobiles. When carbon fiber is used to process the car frame, it needs to be laser-engraved to engrave patterns or text on the carbon fiber frame. Tooling structures are required to fix the carbon fiber frame.

[0003] Existing carbon fiber mid-frames cannot be quickly fixed during laser engraving, resulting in low engraving efficiency. Furthermore, the existing fixtures for laser engraving of carbon fiber mid-frames cannot be used to limit the movement of mid-frames of different sizes, making them inconvenient and limiting their application. Therefore, we propose a new fixture structure for laser engraving of carbon fiber mid-frames to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling structure for laser engraving of carbon fiber midframes, so as to solve the problems currently in the market mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling structure for laser engraving of a carbon fiber mid-frame, comprising a base, a mounting seat installed at the top center of the base, and a mid-frame support installed above the mounting seat, wherein...

[0006] The four corners of the bottom of the mounting base are fixedly connected to the base via support legs. The middle frame bracket is detachably connected to the mounting base via a quick-release mechanism. The middle frame is provided directly above the middle frame bracket. The base is symmetrically connected to rotating arms on both sides of the top of the middle frame bracket.

[0007] A pressure plate is fixedly connected to the end of the rotating arm away from the rotation point. A bidirectional hydraulic rod is installed at the top center of the base. Racks are symmetrically installed at both ends of the bidirectional hydraulic rod. Transmission teeth are fixedly provided on the outer side of the end of the rotating arm corresponding to the rack.

[0008] Preferably, the quick-assembly and disassembly mechanism includes mounting slots, with mounting slots symmetrically provided on the top of both sides of the mounting base. A mounting block is fixedly connected to the bottom of the mounting slot corresponding to the middle frame bracket. A locking rod slot is provided on the inner wall of the mounting slot. A locking groove is provided on one side of the mounting block corresponding to the locking rod slot. A locking rod is provided in the locking rod slot. An adjusting screw is threadedly connected to the end of the locking rod away from the mounting slot. A transmission slot is provided in the middle of the mounting base. A first reversing gear is fixedly connected to one end of the adjusting screw located in the transmission slot. A second reversing gear is rotatably connected to the lower part of the transmission slot. A handle is installed on the shaft end of the second reversing gear near the lower part of the mounting base.

[0009] Preferably, the locking rod is a rectangular column, and the external dimensions of the locking rod match the internal dimensions of the locking rod groove, and the lower part of the locking rod away from the adjusting screw and the bottom of the locking groove are both inclined surfaces.

[0010] Preferably, the second reversing gear meshes with the first reversing gear, and the grooves of the adjusting screws on both sides are in the same direction.

[0011] Preferably, the tooth pitch of the rack is equal to the tooth pitch of the transmission teeth, and the rack meshes with the transmission teeth.

[0012] Preferably, the base has a groove at the top corresponding to the rack, and a slider is fixedly connected to the bottom of the rack corresponding to the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention relates to a method for laser engraving carbon fiber frames. The frame is placed on a matching frame support. A bidirectional hydraulic rod pushes two racks apart, causing them to rotate simultaneously towards the frame support via transmission gears. This rotation of the racks, in turn, causes pressure plates to press against the sides of the frame, securing it in place. The frame support is detachably connected to the mounting base via a quick-release mechanism, allowing for easy replacement according to the frame's dimensions. This fixture structure enables laser engraving on the frame and quick fixation, preventing movement and offsetting the engraving position. Furthermore, the easily replaceable frame support allows for fixing frames of different sizes.

[0015] This invention, when the middle frame bracket needs to be replaced, uses a handle to drive the second reversing gear to rotate. The second reversing gear meshes with the first reversing gears on both sides, causing the adjusting screws on both sides to rotate simultaneously in opposite directions. This causes the locking rods on both sides to move out of the locking groove simultaneously, allowing the mounting block to be removed from the mounting groove, thus disassembling the middle frame bracket. Afterwards, the middle frame bracket to be installed is taken out, and the middle frame bracket, along with the mounting block, is inserted into the mounting groove. The handle is then rotated in the opposite direction, causing the locking rods on both sides to move away from each other, allowing them to insert into the locking groove. As the locking rods are inserted, the inclined surfaces of the locking groove and the locking rods cause the locking rods to exert a downward force on the mounting block, thus ensuring the middle frame bracket is tightly against the top of the mounting base. This prevents the middle frame bracket from shaking during installation, effectively providing stability for the middle frame bracket installation. Furthermore, the quick-release mechanism allows for rapid replacement of the middle frame bracket, facilitating the clamping of middle frames of different sizes. Attached Figure Description

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a tooling structure for laser engraving of a carbon fiber frame, including a base 1, a mounting seat 2 installed at the top center of the base 1, and a frame support 3 installed above the mounting seat 2.

[0023] The four corners of the bottom of the mounting base 2 are fixedly connected to the base 1 by the support legs 4. The middle frame bracket 3 is detachably connected to the mounting base 2 by a quick disassembly mechanism. The middle frame 15 is provided on the top of the middle frame bracket 3. The base 1 is symmetrically connected to the top of both sides of the middle frame bracket 3 by rotating arms 16.

[0024] A pressure plate 17 is fixedly connected to one end of the rotating arm 16 away from the rotating part. A bidirectional hydraulic rod 18 is installed at the top center of the base 1. A rack 19 is symmetrically installed at both ends of the bidirectional hydraulic rod 18. A transmission tooth 20 is fixedly provided on the outer side of the end of the rotating arm 16 corresponding to the rack 19.

[0025] When laser engraving is required on the carbon fiber frame, the frame 15 is placed on the frame bracket 3 with the same size. The two-way hydraulic rod 18 pushes the racks 19 on both sides away from each other, so that the racks 19 drive the rotating arms 16 on both sides to rotate simultaneously towards the frame bracket 3 through the transmission gear 20. This causes the pressure plate 17 to press down on both sides of the frame 15 by rotation, thus fixing the frame 15. The frame bracket 3 is detachably connected to the mounting base 2 through a quick-release mechanism, which makes it easy to replace the frame bracket 3 according to the size of the frame 15. With this tooling structure, laser engraving can be performed on the frame 15, and it can be quickly fixed to prevent it from shaking and causing the engraving position to shift. At the same time, the quick-replaceable frame bracket 3 can fix the frame 15 of different sizes.

[0026] Please see Figures 1 to 4The quick-assembly and disassembly mechanism includes mounting slots 5. Mounting slots 5 are symmetrically formed on the top of both sides of the mounting base 2. A mounting block 6 is fixedly connected to the bottom of the mounting slot 5 corresponding to the middle frame bracket 3. A locking rod groove 7 is formed on the inner wall of the mounting slot 5. A locking groove 8 is formed on one side of the mounting block 6 corresponding to the locking rod groove 7. A locking rod 9 is installed in the locking rod groove 7. An adjusting screw 10 is threadedly connected to the end of the locking rod 9 away from the mounting slot 5. A transmission groove 11 is formed in the middle of the mounting base 2. A first reversing gear is fixedly connected to one end of the adjusting screw 10 located in the transmission groove 11. 12. A second reversing gear 13 is rotatably connected to the lower part of the transmission groove 11. A handle 14 is installed on the shaft end of the second reversing gear 13 near the lower part of the mounting base 2. The locking rod 9 is rectangular and cylindrical, and the external dimensions of the locking rod 9 match the internal dimensions of the locking rod groove 7. The lower part of the locking rod 9 away from the adjusting screw 10 and the bottom of the locking groove 8 are both inclined surfaces. The second reversing gear 13 meshes with the first reversing gear 12. The groove directions of the adjusting screws 10 on both sides are the same. When it is necessary to further adjust the middle frame bracket 3... During replacement, the handle 14 drives the second reversing gear 13 to rotate. The second reversing gear 13 meshes with the first reversing gears 12 on both sides, causing the adjusting screws 10 on both sides to rotate in opposite directions simultaneously. This causes the locking rods 9 on both sides to move out of the lock groove 8 simultaneously, allowing the mounting block 6 to move out of the mounting groove 5, thus completing the disassembly of the middle frame bracket 3. Then, the middle frame bracket 3 to be installed is taken out, and the middle frame bracket 3 drives the mounting block 6 to be inserted into the mounting groove 5. The handle 14 is rotated in the opposite direction, causing the locking rods 9 on both sides to move away from each other, so that the locking rods 9 are inserted into the lock groove 8. As the locking rods 9 are inserted, the inclined surfaces of the lock groove 8 and the locking rods 9 cause the locking rods 9 to drive the mounting block 6 to generate a downward force, thus making the middle frame bracket 3 fit tightly against the top of the mounting base 2. This prevents the middle frame bracket 3 from shaking during installation, effectively providing stability for the installation of the middle frame bracket 3. At the same time, the quick-release mechanism allows for the rapid replacement of the middle frame bracket 3, so as to clamp middle frames 15 of different sizes.

[0027] Please see Figures 1 to 4 The tooth pitch of rack 19 is equal to that of transmission gear 20, and rack 19 meshes with transmission gear 20. Base 1 has a groove 21 corresponding to the top of rack 19, and a slider 22 is fixedly connected to the bottom of groove 21 corresponding to rack 19. When rack 19 moves, rack 19 drives slider 22 to move in groove 21 (the opening of groove 21 is blocked by a flexible cover to prevent dust generated during carving from falling into the interior of groove 21. In order to show the structure of groove 21 and slider 22, the attached figure is in an exposed state. The flexible cover is commonly used to cover the slide rail structure, so its structure and principle are not explained in detail). The guide structure formed by slider 22 and groove 21 guides the movement of rack 19 to prevent the movement of rack 19 from deviating, so that rack 19 and transmission gear 20 can drive rotating arm 16 to rotate stably.

[0028] Working principle: This fixture structure for laser engraving of carbon fiber mid-frames allows for laser engraving of the carbon fiber mid-frame. The mid-frame 15 is placed on a mid-frame support 3 of the same size. A bidirectional hydraulic rod 18 pushes the two racks 19 away from each other, causing the racks 19 to rotate simultaneously towards the mid-frame support 3 via the transmission gear 20. This rotation causes the pressure plate 17 to press against both sides of the mid-frame 15, thus fixing the mid-frame 15 in place. The mid-frame support 3 is detachably connected to the mounting base 2 via a quick-release mechanism, facilitating replacement of the mid-frame support 3 according to the size of the mid-frame 15. This fixture structure enables laser engraving on the mid-frame 15, quickly fixing it and preventing wobbling that could cause the engraving position to shift. The easily replaceable mid-frame support 3 also allows for fixing mid-frames 15 of different sizes.

[0029] When the middle frame bracket 3 needs to be replaced, the handle 14 drives the second reversing gear 13 to rotate. The second reversing gear 13 meshes with the first reversing gears 12 on both sides, causing the adjusting screws 10 on both sides to rotate in opposite directions simultaneously. This causes the locking rods 9 on both sides to move out of the lock groove 8 simultaneously, allowing the mounting block 6 to move out of the mounting groove 5, thus completing the disassembly of the middle frame bracket 3. After that, the middle frame bracket 3 to be installed is taken out, and the middle frame bracket 3 drives the mounting block 6 to be inserted into the mounting groove 5. The handle 14 is rotated in the opposite direction, causing the locking rods 9 on both sides to move away from each other, so that the locking rods 9 are inserted into the lock groove 8. As the locking rods 9 are inserted, the inclined surfaces of the lock groove 8 and the locking rods 9 cause the locking rods to move out of the lock groove 8, thus... The locking rod 9 drives the mounting block 6 to generate a downward force, thereby making the middle frame bracket 3 tightly adhere to the top of the mounting base 2. When the middle frame bracket 3 is installed, it prevents the middle frame bracket 3 from shaking, effectively providing stability for the installation of the middle frame bracket 3. At the same time, the set quick disassembly and assembly mechanism allows the middle frame bracket 3 to be quickly replaced, so as to clamp middle frames 15 of different sizes. When the rack 19 moves, the rack 19 drives the slider 22 to move within the slide groove 21. The guide structure formed by the slider 22 and the slide groove 21 guides the movement of the rack 19, preventing the rack 19 from deviating, so that the rack 19 and the transmission gear 20 can drive the rotating arm 16 to rotate stably.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
