Description

Technical Field

[0001] This utility model relates to the field of furniture processing technology, and in particular to a furniture processing positioning milling structure. Background Technology

[0002] Most furniture is made of wood or metal. In the process of processing furniture, in addition to simple cutting and sanding, milling is also required. In order to ensure the overall aesthetics and processing accuracy, a positioning milling structure for furniture processing is needed.

[0003] Referring to the Chinese Patent Publication No. CN217669907U, a positioning and milling structure for furniture processing is disclosed, including a processing table, two sets of support plates, a clamping assembly, a positioning assembly, and a milling assembly. The processing table is made of metal. The two sets of support plates are symmetrically installed on both sides of the processing table. The clamping assembly is installed at the top of the processing table. The positioning assembly is installed at the top of the processing table and located to one side of the clamping assembly. The milling assembly is installed above the positioning assembly. This utility model, by incorporating the positioning assembly, allows for precise positioning of the processing location by rotating a handle before processing. Rotating the handle drives a first transmission screw to rotate. A limiting plate limits the first transmission screw. The rotation of the first transmission screw causes a first screw nut to move, which in turn moves a positioning ruler. During this movement, the positioning ruler slides along one side of the limiting rod, thus ensuring accurate processing.

[0004] By referring to the above comparative documents, it can be seen that the existing technology still has the following shortcomings. Since furniture is generally composed of flat panels and cylindrical materials, the flat panels or cylindrical materials need to be milled before they are processed into furniture. However, most existing technologies can only mill flat panels. When encountering cylindrical materials, it is difficult to clamp and fix the cylindrical materials. Therefore, it is necessary to change to other milling structures for processing, resulting in poor practicality of the existing milling structures. In addition, the existing milling structures are generally equipped with only one milling cutter. When it is necessary to change to other specifications of milling cutters, disassembly and replacement are required, which is relatively troublesome. Utility Model Content

[0005] This utility model provides a positioning milling structure for furniture processing, which facilitates convenient milling of flat panels or cylindrical materials, and also facilitates easy replacement of milling cutters of other specifications.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A furniture processing positioning milling structure includes a frame and a recessed rail, wherein the recessed rail is fixed inside the frame;

[0008] Both sides of the upper end of the concave rail are provided with concave support plates, and clamping plates are slidably connected inside the concave support plates. Threaded pressure rods are rotatably connected to the upper end of the clamping plates. Threaded pressure rods are threaded through the upper surface of the concave support plates. V-shaped grooves are opened at the bottom of the concave rail. Spacing adjustment components are provided inside the concave rail.

[0009] The lower end of the tool holder is equipped with several milling cutters of different specifications. Each milling cutter is provided with a threaded adjusting rod rotatably connected to the upper end of the tool holder. Each threaded adjusting rod is threadedly sleeved with a lifting frame. Each lifting frame slides through the bottom of the tool holder, and a drive motor is fixed at the lower end of each lifting frame. Each milling cutter is connected to the power end of the adjacent drive motor.

[0010] Furthermore, the spacing adjustment assembly includes an adjustment block and a bidirectional lead screw. The adjustment block has two parts, each fixed to the lower end of two concave support plates, and both adjustment blocks are slidably connected to the concave rail.

[0011] Furthermore, the bidirectional lead screw thread passes through two adjusting blocks, and both the left and right ends of the bidirectional lead screw rotate and pass through the concave rail.

[0012] Furthermore, a guide rod is fixed at the top of the machine frame, a slider is slidably sleeved around the guide rod, an electric cylinder is fixed at the lower end of the slider, and the upper end of the tool holder is connected to the power end of the electric cylinder.

[0013] Furthermore, a forward and reverse motor is fixed on the right side of the top of the frame, and a sliding screw is connected to the power end of the forward and reverse motor. The end of the sliding screw is rotatably connected to the left wall of the frame, and the slider is threadedly connected to the sliding screw.

[0014] Furthermore, handles are fixed to the upper end of the threaded pressure rod, the upper end of the threaded adjustment rod, and the left and right ends of the bidirectional lead screw.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting concave support plates and adjusting the distance between the two concave support plates, it is convenient to support flat plates of various lengths for milling. Moreover, by placing cylindrical materials in V-grooves and clamping them with clamping plates, it is convenient to support cylindrical materials of various lengths for milling. In summary, this milling structure is convenient for milling flat plates or cylindrical materials, effectively ensuring the practicality of the milling structure.

[0017] 2. By setting multiple milling cutters and using a threaded adjustment rod to facilitate easy replacement of milling cutters of the corresponding specifications, the trouble of disassembling and replacing milling cutters is effectively reduced, making operation convenient.

[0025] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0026] like Figure 1-3 As shown, in this embodiment, the machine includes a frame 1 and a concave rail 2. The concave rail 2 is fixed inside the frame 1. Concave support plates 3 are provided on both sides of the upper end of the concave rail 2. Clamping plates 7 are slidably connected inside the concave support plates 3. Threaded pressure rods 8 are rotatably connected to the upper ends of the clamping plates 7. The threaded pressure rods 8 are threaded through the concave support plates 3. V-grooves 6 are opened at the bottom of the concave rail 2. Handles are fixed to the upper ends of the threaded pressure rods 8, the upper ends of the threaded adjusting rods 17, and the left and right ends of the bidirectional lead screw 5.

[0027] When milling flat panels or cylindrical materials for furniture using this milling structure, the flat panel is supported by the bottom of the concave support plate 3, or the cylindrical material is supported by the V-groove 6. Then, by turning the threaded pressure rod 8 with the handle, the clamping plate 7 is moved down until the clamping plate 7 clamps and fixes the flat panel or cylindrical material. Therefore, this milling structure is convenient for milling flat panels or cylindrical materials, and effectively ensures the practicality of the milling structure.

[0028] like Figure 1As shown in this embodiment, the recessed rail 2 is provided with a spacing adjustment component. The spacing adjustment component includes an adjustment block 4 and a bidirectional lead screw 5. There are two adjustment blocks 4, which are fixed to the lower ends of the two concave support plates 3. The adjustment blocks 4 are slidably connected to the recessed rail 2. The bidirectional lead screw 5 is threaded through the two adjustment blocks 4, and the left and right ends of the bidirectional lead screw 5 rotate through the recessed rail 2.

[0029] When it is necessary to adjust the support spacing between the two concave support plates 3, the double-acting screw 5 is turned by turning the handle. The double-acting screw 5 will drive the adjusting block 4 to slide along the concave rail 2. Therefore, the adjusting block 4 will drive the concave support plates 3 to move together, thereby shortening or lengthening the spacing between the two concave support plates 3. This facilitates the adjustment of the support spacing between the two concave support plates 3, making it suitable for supporting flat plates or cylindrical materials of various lengths for milling, thus improving the practicality of the milling structure.

[0030] like Figure 4 , 5 As shown in this embodiment, the lower end of the tool holder 13 is provided with several milling cutters 14 of different specifications. Each milling cutter 14 is provided with a threaded adjusting rod 17 rotatably connected to the upper end of the tool holder 13. Each threaded adjusting rod 17 is threadedly sleeved with a lifting frame 16. Each lifting frame 16 slides through the bottom of the tool holder 13, and a drive motor 15 is fixed at the lower end of each lifting frame 16. Each milling cutter 14 is connected to the power end of the adjacent drive motor 15. A guide rod 9 is fixed at the top of the inner frame 1. A slider 10 is slidably sleeved around the guide rod 9. An electric cylinder 12 is fixed at the lower end of the slider 10. The upper end of the tool holder 13 is connected to the power end of the electric cylinder 12.

[0031] When it is necessary to replace the milling cutter 14 for processing, the threaded adjusting rod 17 is turned by turning the handle, which moves the lifting frame 16 downward. The lifting frame 16 will drive the drive motor 15 and the milling cutter 14 to move downward together until the milling cutter 14 of the corresponding specification moves down to the working position. Then, the operation of the electric cylinder 12 drives the tool holder 13 and the milling cutter 14 to move downward. The drive motor 15 drives the corresponding milling cutter 14 to work. The corresponding milling cutter 14 will then perform milling processing on flat plates or cylindrical materials. Therefore, it is convenient to replace the milling cutter 14 of the corresponding specification, thereby effectively reducing the trouble of disassembling and replacing the milling cutter 14 and making the operation convenient.

[0032] like Figure 1 As shown, in this embodiment, a forward and reverse motor 18 is fixed on the right side of the top of the frame 1. The power end of the forward and reverse motor 18 is connected to a sliding screw 19. The end of the sliding screw 19 is rotatably connected to the left wall of the frame 1. The slider 10 is threadedly connected to the sliding screw 19.

[0033] When it is necessary to adjust the machining position of the milling cutter 14, the operation of the forward and reverse motor 18 drives the sliding screw 19 to rotate. The sliding screw 19 will drive the slider 10 to slide back and forth along the guide rod 9. Therefore, the slider 10 will drive the electric cylinder 12, the tool holder 13 and the milling cutter 14 to move back and forth together, thereby adjusting the machining position of the milling cutter 14.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementations of this utility model. In addition, other implementations are also included. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
