Detailed Implementation
[0041] The present invention will now be described in further detail with reference to the accompanying drawings.
[0042] Please see Figure 1-8 As shown, this embodiment provides a fixing device for machining mechanical parts, including a base with a placement area on its top. Two sets of mounting plates are slidably disposed on the base along the placement area. A driving assembly for driving the two sets of mounting plates to slide relative to each other is provided on the base. Multiple movable blocks are slidably disposed on the mounting plates. Movable grooves for sliding are provided through the movable blocks. Multiple positioning holes are provided through the mounting plates along the extension direction of the moving grooves. Positioning assemblies for positioning the positioning holes are provided on the movable blocks. A threaded rod is slidably connected through and to the movable blocks. A clamping plate is provided on the threaded rod. An adjusting assembly for adjusting the threaded rod is provided on the movable blocks.
[0043] Specifically, the parts are placed in the placement area, and the position of the movable block is adjusted according to the shape of the parts, allowing it to slide on the mounting plate via the movable slot. The movable block is then moved to a suitable position on the mounting plate, and the position of the movable block is fixed using a positioning component. Afterward, the position of the threaded rod can be adjusted using an adjustment component, i.e., the position of the clamping plate. Then, the drive component works, causing the two sets of mounting plates to slide relative to each other on the base along the placement area, thereby clamping and fixing the mechanical parts placed in the placement area. The distance between the two mounting plates can be flexibly adjusted using the drive component to accommodate parts of different widths. Multiple movable blocks and positioning components allow users to accurately position the movable blocks at different positions on the mounting plate according to the shape and size of the parts, achieving the fixation of parts of different shapes. The adjustment component can easily adjust the threaded rod, thereby flexibly adjusting the position of the clamping plate, enhancing the flexibility and applicability of fixing parts, and improving the versatility of the fixing device.
[0044] It should be noted that in this embodiment, each mounting plate is provided with two moving slots, and two moving blocks are movably arranged in each moving slot. Of course, there are no restrictions in other embodiments. At the same time, the moving blocks are detachably arranged in the moving slots to facilitate subsequent maintenance. Secondly, the moving blocks have a square structure.
[0045] In this embodiment, as Figures 1 to 8 As shown, the positioning assembly includes a fixed plate, which is fixedly mounted on the movable block, and a clamping plate, which is detachably mounted on the movable block relative to the fixed plate. Multiple second positioning bolts are fixedly mounted on the clamping plate relative to the positioning holes. The fixed plate has through-holes for the positioning bolts to pass through. Specifically, when the movable block needs to be fixed, the clamping plate is installed on the movable block at a position opposite to the fixed plate, so that the second positioning bolts on the clamping plate pass through the positioning holes and the second bolt holes on the fixed plate, and are fixed with nuts, thereby fixing the movable block to the mounting plate. This positioning assembly has a simple structure and is easy to operate. Through the cooperation of the second positioning bolts and the positioning holes, the movable block can be positioned relatively stably on the mounting plate, ensuring that the movable block will not shift during the part processing, guaranteeing the stability of the fixation, and thus ensuring processing accuracy. It should be noted that in this embodiment, the dimensions of both the fixed plate and the clamping plate are larger than the dimensions of the movable block.
[0046] In this embodiment, as Figures 4 to 8As shown, the positioning assembly includes a worm gear rotatably mounted on a fixed plate, a threaded rod passing through and movably mounted on the worm gear, and an adjusting plate fixedly mounted on the fixed plate. A worm gear meshing with the worm gear is rotatably connected to the adjusting plate. Specifically, by rotating the worm gear, the worm gear drives the meshing worm gear to rotate. Since the threaded rod passes through and movably mounted on the worm gear, the rotation of the worm gear drives the threaded rod to rotate, thereby adjusting the threaded rod and thus adjusting the position of the clamping plate. The worm gear transmission structure has a self-locking characteristic, effectively preventing the threaded rod from rotating on its own due to external forces after the threaded rod position is adjusted, ensuring the clamping plate position is fixed and stable. This improves the reliability of clamping parts and ensures the stability of parts during processing. Simultaneously, this structure allows for relatively precise fine-tuning, meeting the requirements of high-precision machining.
[0047] In this embodiment, as Figures 6 to 8 As shown, the clamping plate is detachably mounted on the threaded rod. An insert block is fixedly mounted on the clamping plate. The threaded rod has a slot for inserting the insert block. A first bolt hole is provided through the insert block. A first positioning bolt is provided on the threaded rod to position the insert block by inserting into the first bolt hole. Specifically, when installing the clamping plate, the insert block on the clamping plate is inserted into the slot on the threaded rod. Then, the first positioning bolt is used to pass through the first bolt hole on the insert block, thereby fixing the clamping plate on the threaded rod. The detachable design of the clamping plate makes it convenient to replace different types of clamping plates according to the shape and material of different parts.
[0048] In this embodiment, as Figures 5 to 8 As shown, the clamping plate has a through groove that passes through the moving block. The through groove can be fitted and snapped onto the moving block. Specifically, when installing the clamping plate, the through groove is fitted onto the moving block so that the clamping plate snaps onto the moving block, and then the clamping plate is fixed to the fixed plate. The design of the through groove fitting and snapping onto the moving block makes the installation of the clamping plate more convenient, reduces installation time, and improves work efficiency.
[0049] In this embodiment, as Figures 4 to 7 As shown, a second slider is fixedly installed on the movable block, and a second sliding groove is provided in the mounting plate for the second slider to slide. The second sliding groove is connected to the movable groove.
[0050] In this embodiment, as Figures 1 to 3As shown, multiple sets of guide plates are fixedly installed on the base. Guide rods are movably connected to the mounting plates through the guide plates. Specifically, the guide plates on the base guide the guide rods. When the drive assembly moves the mounting plates, the guide rods slide within the guide plates, restricting the direction of movement of the mounting plates. This ensures that the mounting plates can only slide relative to each other along the placement area. The design of the guide plates and guide rods improves the stability and accuracy of the mounting plate movement, ensuring that the mounting plates can move in the predetermined direction and preventing the mounting plates from shifting or shaking during movement. This allows for more precise adjustment of the distance between the two mounting plates, improving the stability and reliability of fixing the components and helping to ensure machining accuracy.
[0051] In this embodiment, as Figures 1 to 5 As shown, the mounting plate has a threaded hole through the moving slot, and a fixing screw is threaded onto the threaded hole. Specifically, the fixing screw helps to improve the stability of the mounting plate and at the same time blocks the moving slot to prevent the moving block from detaching from the moving slot.
[0052] In this embodiment, as Figures 1 to 3 As shown, the drive assembly includes a double-ended screw, which is rotatably mounted within a base. A motor that drives the double-ended screw to rotate is fixedly mounted on the base. Two first sliders are nested opposite each other and threadedly connected to the two ends of the double-ended screw. The two first sliders are respectively fixedly connected to two mounting plates. The base has a first sliding groove for the first sliders to slide. A reinforcing plate is fixedly mounted between the first sliders and the mounting plates. Specifically, the motor is controlled by an external control device to drive the double-ended screw to rotate. The two first sliders at both ends of the double-ended screw will slide relative to each other, thereby causing the two mounting plates fixedly connected to them to slide relative to each other on the base along the placement area. The reinforcing plate improves the strength and stability of the connection between the first sliders and the mounting plates, preventing damage to the connection between the first sliders and the mounting plates due to uneven force during the movement of the mounting plates. This extends the service life of the fixing device and ensures the smooth movement of the mounting plates, thereby improving the reliability of fixing the components.
[0053] Working principle:
[0054] The components are placed in the placement area, and then the position of the moving block is adjusted according to the shape of the components, allowing it to slide on the mounting plate through the moving groove. The moving block is moved to a suitable position on the mounting plate, so that the second positioning bolt on the clamping plate passes through the positioning hole and the second bolt hole on the fixing plate, and is fixed with a nut, thereby fixing the moving block to the mounting plate. Then, by rotating the worm gear, the worm gear drives the worm wheel that meshes with it to rotate. Since the threaded rod passes through and is movably mounted on the worm wheel, the rotation of the worm wheel drives the threaded rod to rotate, thereby adjusting the threaded rod and thus adjusting the position of the clamping plate. Finally, the motor is controlled by an external control device to drive the double head. When the screw rotates, the two first sliders at both ends of the double-ended screw slide relative to each other, thereby driving the two mounting plates fixedly connected to them to slide relative to each other on the base along the placement area, thus clamping and fixing the mechanical parts placed in the placement area. The distance between the two mounting plates can be flexibly adjusted by the drive component to adapt to parts of different widths. Multiple moving blocks and positioning components allow users to accurately position the moving blocks at different positions on the mounting plates according to the shape and size of the parts, realizing the fixing of parts of different shapes. The adjustment component can easily adjust the threaded rod, thereby flexibly adjusting the position of the clamping plate, enhancing the flexibility and applicability of fixing parts, and improving the versatility of the fixing device.
