Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of irregular plate processing equipment, specifically to a milling and leveling structure for irregular plates. Background Technology
[0002] Milling is a machining method that uses a milling cutter as a cutting tool to machine the surface of an object. Milling refers to cutting a workpiece with a rotating multi-edged cutting tool, and it is a highly efficient machining method. During operation, the cutting tool rotates (performs the main motion), and the workpiece moves (performs the feed motion). The workpiece can also be fixed, but in this case, the rotating cutting tool must also move (simultaneously completing the main motion and feed motion).
[0003] When milling sheet metal, the sheet is placed on a machining table and fixed in place by a fixing device. The position of the milling cutter is adjusted to ensure contact between the cutter and the sheet, allowing for turning. However, existing milling methods for irregularly shaped workpieces often involve adjusting the height of the milling cutter to ensure proper cutting of the inclined surface. This requires multiple milling passes, making the process complex and time-consuming. Therefore, we propose a leveling structure for milling irregularly shaped sheet metal. Utility Model Content
[0004] To address the shortcomings of existing milling and leveling structures for irregularly shaped plates, this utility model provides a milling and leveling structure for irregularly shaped plates. This structure has the advantage of adjusting the workpiece angle according to the different cutting surface angles after the workpiece is placed on the machining table, thereby improving cutting efficiency and solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a milling and leveling structure for irregularly shaped plates, including a boring and milling machine worktable. A second slide groove is provided on the upper part of the boring and milling machine worktable. A first support plate and a second support plate are installed on the upper part of the boring and milling machine worktable and directly above the second slide groove. An mounting plate is fixedly connected to the upper part of the first support plate. Brackets are installed at the front and rear ends of the upper part of the mounting plate by fastening bolts. A processing table is movably sleeved on the outside of the brackets. Connecting plates are installed on both sides of the upper part of the mounting plate. A lead screw is installed in the internal thread of the connecting plate. A wedge block is movably sleeved on the inner side of the lead screw. An irregularly shaped plate is placed on the upper part of the processing table.
[0006] Effectively, sliders are installed on the sides of the first and second support plates, the sliders are movably sleeved inside the second slide groove, and bolts with limiting functions are installed inside the sliders.
[0007] Effectively, the lower part of the mounting plate has a first sliding groove, and the upper end of the second support plate is sleeved inside the first sliding groove.
[0008] Effectively, a pin is installed through the inside of the bracket, and a bearing is installed between the bracket and the processing table.
[0009] Effectively, the upper part of the processing table is provided with a positioning hole, and a limit pin is installed inside the positioning hole. The limit pin is attached to the outside of the irregular plate.
[0010] Effectively, the lower end of the wedge block is fitted to the upper part of the mounting plate, and the upper end of the wedge block forms a 45° inclined surface, which contacts one side of the lower end of the processing table.
[0011] Effectively, the mounting plate has a cushioning pad installed inside, which is located at the four corners of the lower end of the processing table.
[0012] Compared with existing milling leveling structures, this utility model has the following advantages:
[0013] 1. This milling leveling structure for irregularly shaped plates allows for the installation of the irregularly shaped plate on the upper part of the machining table. By rotating the lead screw, the lead screw pushes the wedge block to move inward, thus lifting one end of the machining table. This allows for adjustment of the tilt angle of the machining table, ensuring that the outer cutting surface of the irregularly shaped plate remains parallel to the horizontal plane, thereby improving cutting efficiency.
[0014] 2. The milling and leveling structure for irregularly shaped plates adjusts the position of the second support plate at the lower end of the mounting plate according to the different spacing between the two sets of second slide grooves. At the same time, the first support plate and the second support plate drive the slider to move and fit inside the two sets of second slide grooves. Bolts are installed inside the slider, so that the mounting plate maintains controllability and stability when it is positioned at the upper end of the boring and milling machine worktable.

[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 Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A milling and leveling structure for irregularly shaped plates includes a boring and milling machine table 1. A second slide groove 2 is formed on the upper part of the boring and milling machine table 1. A first support plate 3 and a second support plate 5 are installed on the upper part of the boring and milling machine table 1, directly above the second slide groove 2. After the first support plate 3 and the second support plate 5 drive the slider 6 to be installed inside the second slide groove 2, the mounting plate 4 maintains stability when its position is limited at the upper end of the boring and milling machine table 1. The mounting plate 4 is fixedly connected to the upper part of the first support plate 3. Brackets 8 are installed at the front and rear ends of the upper part of the mounting plate 4 by fastening bolts. The external movement of the brackets 8... A processing table 10 is fitted onto a support 8, which limits the position of the processing table 10. The processing table 10 rotates around the outside of the support 8. Connecting plates 13 are installed on both sides of the upper part of the mounting plate 4. A lead screw 14 is installed in the internal thread of the connecting plate 13. A wedge block 15 is movably fitted on the inner side of the lead screw 14. When the connecting plate 13 is rotated, the connecting plate 13 pushes the wedge block 15 to move inside the processing table 10. At the same time, the wedge block 15 pushes one end of the processing table 10 periodically, thereby adjusting the tilt angle of the processing table 10. An irregularly shaped plate 16 is placed on the upper part of the processing table 10.
[0023] Please see Figure 1A slider 6 is installed on the side of the first support plate 3 and the second support plate 5. The slider 6 is movably sleeved inside the second slide groove 2. A bolt 7 with a limiting function is installed inside the slider 6. The slider 6, which is installed on both sides of the first support plate 3 and the mounting plate 4, is movably sleeved inside the second slide groove 2. At the same time, a bolt 7 is installed inside the slider 6. The bolt 7 passes through the slider 6 and contacts the second slide groove 2. Thus, the position of the mounting plate 4 on the upper part of the boring and milling machine table 1 can be limited, thereby improving the stability and convenience of the mounting plate 4 when it is installed on the upper part of the boring and milling machine table 1.
[0024] Please see Figure 2 The mounting plate 4 has a first sliding groove at its lower part, and the upper end of the second support plate 5 is fitted inside the first sliding groove. The mounting plate 4 has a first sliding groove at its lower part, and the second support plate 5 is movably fitted on the lower end of the mounting plate 4. Depending on the different distances between the two sets of second sliding grooves 2, the first support plate 3 is installed on the upper part of one set of second sliding grooves 2, and the second support plate 5 is installed on the upper part of the other set of second sliding grooves 2. Thus, when the distances between the two sets of second sliding grooves 2 are different, the first support plate 3 and the second support plate 5 can be driven to limit the position of the mounting plate 4.
[0025] Please see Figure 2 A pin 11 is installed through the inside of the bracket 8. A bearing 9 is installed between the bracket 8 and the processing table 10. The bearing 9 is installed between the bracket 8 and the processing table 10 to reduce the frictional resistance when the processing table 10 rotates. At the same time, the pin 11 is installed inside the bracket 8 and passes through the bracket 8 and the processing table 10, thereby limiting the position of the processing table 10. The angle at which the bracket 8 drives the processing table 10 can be adjusted.
[0026] Please see Figure 1 The upper part of the processing table 10 is provided with a positioning hole 12. A limit pin is installed inside the positioning hole 12. The limit pin is attached to the outside of the irregular plate 16. The positioning hole 12 is provided on the outside of the processing table 10. According to the different shapes of the irregular plate 16, the irregular plate 16 is placed on the upper part of the processing table 10. At the same time, according to the different shapes of the irregular plate 16, a limit pin is installed inside the corresponding positioning hole 12. The limit pin carries the irregular plate 16 to the upper position of the processing table 10 and limits its position.
[0027] Please see Figure 4 and Figure 5The lower end of the wedge block 15 is fitted to the upper part of the mounting plate 4, and the upper end of the wedge block 15 forms a 45° inclined surface. The inclined surface contacts one side of the lower end of the processing table 10. An inclined surface is formed on the outside of the wedge block 15. After the irregular plate 16 is installed on the upper part of the processing table 10, when it is necessary to cut the irregular surface on the outside of the irregular plate 16, the lead screw 14 is rotated. The lead screw 14 pushes the wedge block 15 to move inward. At the same time, the wedge block 15 lifts one end of the processing table 10, and then the overall tilt angle of the processing table 10 changes. Then the cutting surface of the irregular plate 16 is leveled to ensure that the external leveling and positioning of the irregular plate 16 is convenient.
[0028] Please see Figure 4 The mounting plate 4 has a buffer pad 17 installed inside. The buffer pad 17 is located at the four corners of the lower end of the processing table 10. By installing the buffer pad 17 inside the mounting plate 4, which is located at the four corners of the lower end of the processing table 10, the buffer pad 17 adjusts the maximum deflection angle of the processing table 10 during the adjustment of the angle of the processing table 10. This effectively avoids the processing table 10 deflecting too much, which would cause interference to the installation of the irregular plate 16.
[0029] Working principle: During use, the position of the second support plate 5 at the lower end of the mounting plate 4 is adjusted according to the spacing of the second slide groove 2. At the same time, the first support plate 3 and the second support plate 5 are movably sleeved inside the two sets of second slide grooves 2. After the mounting plate 4 moves to the turning area, the sliders 6 installed on the sides of the first support plate 3 and the second support plate 5 are sleeved inside the second slide groove 2. At the same time, bolts 7 are installed inside the sliders 6. The bolts 7 carry the sliders 6 to maintain stability when the position inside the second slide groove 2 is limited. Meanwhile, the irregular plate 16 is installed on the upper part of the machining table 10. A positioning pin is installed inside the positioning hole 12 to ensure that the irregular plate 16 maintains stability when the position of the irregular plate 16 is limited at the upper end of the machining table 10. At the same time, the lead screw 14 is rotated. When the lead screw 14 pushes the wedge block 15 to move inward, and the wedge block 15 is inside the lead screw 14, one end of the machining table 10 can be lifted. Then the angle of the machining table 10 can be adjusted to ensure that the irregular surface formed on the outside of the irregular plate 16 is parallel to the horizontal plane, and at the same time, the efficiency of cutting the irregular plate 16 is guaranteed.
[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.
