Description

Technical Field

[0001] This utility model relates to the field of milling technology, and in particular to a milling cutting device for a milling machining center. Background Technology

[0002] A milling machining center is a machine tool that integrates multiple machining functions. It is typically equipped with a tool magazine and automatic tool changer, enabling it to continuously complete various machining processes such as milling, drilling, and tapping after a single workpiece clamping. It relies on an advanced computer numerical control (CNC) system, which automates the machining process through pre-programmed machining programs. This equipment features multi-axis linkage machining capabilities, high machining efficiency, and high machining accuracy. The working principle of a milling machining center is similar to that of a milling machine, both utilizing cutting tools to cut the workpiece. On a milling machining center, the workpiece is fixed on the worktable, and the spindle drives the cutting tool to rotate via a transmission device, with the tool performing cutting motion on the workpiece surface. Simultaneously, the CNC system controls the movement and rotation of the cutting tool to complete various complex machining processes. However, a significant amount of metal shavings and waste is generated on the milling machining center's worktable after machining. Traditional methods of handling these shavings mostly involve simple sweeping, which is difficult to perform and, when manually handling the worktable, makes it challenging to remove metal shavings from the edges and corners, and also increases the risk of missing any shavings or waste.

[0003] Therefore, it is necessary to provide a new milling machining center cutting device to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a milling machining center cutting device.

[0005] The milling machining center cutting device provided by this utility model includes a mounting frame, on which a cutting machine for machining workpieces is fixedly mounted and a protective box for covering the cutting machine is mounted. The mounting frame also has a worktable for mounting workpieces. A magnetic suction component for adsorbing metal impurities inside the protective box is installed inside the protective box. The magnetic suction component includes a mounting plate, and a rectangular electromagnet for adsorbing metal impurities is fixedly mounted on the bottom of the mounting plate.

[0006] The protective box is equipped with an adjustment assembly for driving a rectangular electromagnet to move laterally along the worktable.

[0007] Preferably, the adjustment component includes a lead screw, which is rotatably installed inside a protective box and parallel to the worktable. A servo motor for driving the lead screw to rotate is fixedly installed on the outer wall of the protective box via a frame. A limit rod that is distributed vertically and parallel to the lead screw is also fixedly installed on the protective box.

[0008] Preferably, a threaded seat is fixedly installed on the mounting plate, and the threaded seat has a threaded through hole and a sliding through hole. The threaded seat is sleeved on the lead screw through the threaded through hole and threadedly connected to the lead screw. The threaded seat is sleeved on the limit rod through the sliding through hole and slidably connected to the limit rod.

[0009] Preferably, a cleaning assembly for cleaning the lead screw is installed on both sides of the threaded seat, and the cleaning assembly includes a threaded cylinder. A rotating connecting ring is installed at one end of the threaded cylinder and is coaxially arranged, while a cleaning cylinder is installed at the other end of the threaded cylinder and is coaxially arranged. Multiple annularly distributed bristles are fixedly installed on the inner wall of the cleaning cylinder.

[0010] Preferably, the rotating connecting ring is fixedly installed on the side wall of the threaded seat and coaxially arranged with the threaded through hole of the threaded seat, and the threaded sleeve is sleeved on the lead screw and threadedly connected to the lead screw.

[0011] Preferably, a reinforcing rib for connecting the mounting plate and the threaded seat is fixedly installed at the end of the mounting plate away from the threaded seat.

[0012] Preferably, the mounting frame has a slag discharge port that communicates with the inner box of the protective box, and the slag discharge port is located on one side of the workbench, and a curved discharge pipe is fixedly installed at the bottom of the slag discharge port.

[0013] Compared with related technologies, the milling machining center cutting device provided by this utility model has the following beneficial effects:

[0014] 1. This utility model activates a servo motor to drive a lead screw to rotate, and simultaneously activates an electromagnet. The electromagnet can then attract metal scraps and waste that fall onto the workbench and protective box. After attraction is complete, the electromagnet slides to the slag discharge port and the servo motor is turned off. Then the electromagnet is turned off again. Therefore, all the metal scraps and waste attracted by the electromagnet can be discharged through the discharge pipe. A container can be placed at the bottom of the discharge pipe to collect the metal scraps and waste. The whole process is simple and convenient, and it also eliminates the difficulty and omission of metal scraps and waste when manually handling the corners of the workbench in the traditional way.

[0015] 2. When the threaded seat slides along the lead screw, the threaded cylinder on the sliding direction of the threaded seat is subjected to the lateral thrust of the threaded seat, while the threaded cylinder on the other side of the threaded seat is subjected to the lateral pull of the threaded seat. Therefore, the threaded cylinder moves along the lead screw and rotates. Thus, the cleaning cylinder on the threaded cylinder can rotate and use the bristles to clean the metal waste residue on the lead screw, avoiding damage to the threaded seat caused by the metal waste.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 5 The present invention provides a milling machining center cutting device, which includes a mounting frame 1, a magnetic suction component 5, an adjustment component 6, and a cleaning component 7.

[0025] In the embodiments of this utility model, please refer to Figure 1 and Figure 2The mounting frame 1 is fixedly equipped with a cutting machine 3 for processing workpieces and a protective box 2 for covering the cutting machine 3. The mounting frame 1 is also equipped with a worktable 4 for mounting workpieces. After the workpiece is placed on the worktable 4, it is cut by the cutting machine 3 (the cutting machine 3 can be selected according to the requirements and there is no restriction here). Since the mounting frame 1 is equipped with a protective box 2 for covering the cutting machine 3, the metal impurities generated by the cutting machine 3 during milling will not splash to the outside of the mounting frame 1.

[0026] In this embodiment: to facilitate observation by staff, bulletproof transparent glass can be installed on the front and top of the protective box 2.

[0027] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The protective box 2 is equipped with a magnetic suction assembly 5 for adsorbing metal impurities inside the protective box 2. The magnetic suction assembly 5 includes a mounting plate 51. A rectangular electromagnet 53 for adsorbing metal impurities is fixedly installed at the bottom of the mounting plate 51. The protective box 2 is equipped with an adjustment assembly 6 for driving the rectangular electromagnet 53 to move laterally along the worktable 4. The adjustment assembly 6 includes a lead screw 61, which is rotatably installed inside the protective box 2 and arranged parallel to the worktable 4. The outer wall of the protective box 2 is... A servo motor 62 for driving the lead screw 61 to rotate is fixedly installed on the frame. A limit rod 63 that is distributed vertically and parallel to the lead screw 61 is also fixedly installed on the protective box 2. A threaded seat 52 is fixedly installed on the mounting plate 51. The threaded seat 52 has a threaded through hole and a sliding through hole. The threaded seat 52 is sleeved on the lead screw 61 through the threaded through hole and threadedly connected to the lead screw 61. The threaded seat 52 is sleeved on the limit rod 63 through the sliding through hole and slidably connected to the limit rod 63.

[0028] The mounting frame 1 has a slag discharge port 1a that communicates with the inner box of the protective box 2, and the slag discharge port 1a is located on one side of the workbench 4, and a curved discharge pipe 8 is fixedly installed at the bottom of the slag discharge port 1a.

[0029] It should be noted that after the cutting machine 3 finishes cutting the workpiece on the worktable 4, the servo motor 62 is activated to drive the lead screw 61 to rotate. Since the threaded seat 52 is threadedly connected to the lead screw 61 and is limited by the limit rod 63, the threaded seat 52 can drive the electromagnet 53 at the bottom of the mounting plate 51 to slide along the worktable 4. Simultaneously, the electromagnet 53 is activated, allowing it to attract metal chips and slag that fall onto the worktable 4 and the protective box 2. By changing the rotation direction of the servo motor 62, the electromagnet 53 can slide along the worktable 4. The platform 4 slides back and forth continuously, thereby increasing the adsorption force of the electromagnet 53 on the metal scrap. After the adsorption is completed, the electromagnet 53 slides to the slag discharge port 1a and the servo motor 62 is turned off. At this time, the electromagnet 53 is turned off again. Therefore, the metal scrap adsorbed on the electromagnet 53 can be discharged through the discharge pipe 8. A container can be placed at the bottom of the discharge pipe 8 to collect the metal scrap. The whole process is simple and convenient, and it also eliminates the difficulty and omission of metal scrap when manually handling the corners of the workbench 4 in the traditional way.

[0030] Furthermore, a reinforcing rib 54 for connecting the mounting plate 51 and the threaded seat 52 is fixedly installed at the end of the mounting plate 51 away from the threaded seat 52, thereby improving the stability of the mounting plate 51.

[0031] In the embodiments of this utility model, please refer to Figure 3 and Figure 5 The threaded seat 52 is equipped with cleaning components 7 on both sides for cleaning the lead screw 61. The cleaning components 7 include a threaded cylinder 71. One end of the threaded cylinder 71 is equipped with a rotating connecting ring 72 that is rotatably connected and coaxially arranged. The other end of the threaded cylinder 71 is equipped with a cleaning cylinder 73 that is fixedly connected and coaxially arranged. Multiple annularly distributed bristles 74 are fixedly installed on the inner wall of the cleaning cylinder 73. The rotating connecting ring 72 is fixedly installed on the side wall of the threaded seat 52 and is coaxially arranged with the threaded through hole opened in the threaded seat 52. The threaded cylinder 71 is sleeved on the lead screw 61 and threadedly connected to the lead screw 61.

[0032] It should be noted that: since the threaded cylinder 71 is sleeved on the lead screw 61 and threadedly connected to the lead screw 61, and the threaded cylinder 71 is rotatably connected to the threaded seat 52 through the rotating connecting ring 72, when the threaded seat 52 slides along the lead screw 61, the threaded cylinder 71 on the sliding direction of the threaded seat 52 is subjected to the lateral thrust of the threaded seat 52, while the threaded cylinder 71 on the other side of the threaded seat 52 is subjected to the lateral pull of the threaded seat 52. Therefore, the threaded cylinder 71 moves along the lead screw 61 and rotates at the same time. Thus, the cleaning cylinder 73 on the threaded cylinder 71 can rotate and use the bristles 74 to clean the metal shavings remaining on the lead screw 61, avoiding damage to the threaded seat 52 caused by the metal shavings.

[0033] The working principle of the milling machining center cutting device provided by this utility model is as follows:

[0034] After the cutting machine 3 finishes cutting the workpiece on the worktable 4, the servo motor 62 is turned on to drive the lead screw 61 to rotate. Since the threaded seat 52 is threadedly connected to the lead screw 61 and is limited by the limit rod 63, the threaded seat 52 can drive the electromagnet 53 at the bottom of the mounting plate 51 to slide along the worktable 4. At the same time, the electromagnet 53 is turned on so that it can attract the metal scraps and waste that fall onto the worktable 4 and the protective box 2. By changing the rotation direction of the servo motor 62, the electromagnet 53 slides back and forth along the worktable 4, thereby increasing the attraction force of the electromagnet 53 on the metal scraps and waste. After the attraction is completed, the electromagnet 53 slides to the slag discharge port 1a and the servo motor 62 is turned off. At this time, the electromagnet 53 is turned off again, so the metal scraps and waste attracted on the electromagnet 53 can be discharged through the discharge pipe 8. A container can be placed at the bottom to collect metal scraps and slag. The whole process is simple and convenient, and it also eliminates the difficulty and omission of metal scraps and slag when manually handling the four corners of the workbench in the traditional way. Since the threaded cylinder 71 is sleeved on the lead screw 61 and threadedly connected to the lead screw 61, and the threaded cylinder 71 is rotatably connected to the threaded seat 52 through the rotating connecting ring 72, when the threaded seat 52 slides along the lead screw 61, the threaded cylinder 71 in the sliding direction of the threaded seat 52 is subjected to the lateral thrust of the threaded seat 52, while the threaded cylinder 71 on the other side of the threaded seat 52 is subjected to the lateral pull of the threaded seat 52. Therefore, the threaded cylinder 71 moves along the lead screw 61 and rotates at the same time. Thus, the cleaning cylinder 73 on the threaded cylinder 71 can rotate and use the bristles 74 to clean the metal scraps remaining on the lead screw 61, avoiding damage to the threaded seat 52 by the metal scraps.

[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
