DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.
[0028] See also Figure 1-Figure 5 The present application provides a chip removal assembly for a CNC machine tool, comprising a CNC machine tool body 10 , a chip collection assembly 20 and a limit baffle assembly 30 .
[0029] See also Figure 1 and Figure 2The CNC machine tool body 10 includes a bed 110, on which a cutting device 120 is installed. The bed 110 is provided with an open chip recovery chamber 111 at the front end of the cutting device 120, and a downwardly inclined chip guide plate 130 is fixedly connected to one side wall of the chip recovery chamber 111; wherein, when the cutting device 120 is cutting a workpiece, the generated chips and cutting agent will enter the chip recovery chamber 111 along the chip guide plate 130.
[0030] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The debris collection assembly 20 includes a debris suction piece, which is installed inside the debris recovery chamber 111. The inner bottom of the debris recovery chamber 111 is also detachably provided with a debris recovery box 210 and is located below the debris guide plate 130. When cutting, the debris suction piece is started, and the debris suction piece can form a pressure difference between the debris recovery chamber 111 and the outside, so as to ensure that the debris and cutting agent generated by cutting can fall into the debris recovery chamber 111. When the debris enters the debris recovery chamber 111, it will fall into the debris recovery box 210 again. Through the cooperation of the debris suction piece and the debris guide plate 130, the debris and contaminated cutting agent generated by the cutting device 120 during cutting can be collected into the debris recovery box 210, thereby improving the cleaning effect of the debris, and the debris can be recovered after cutting once, thereby improving the cleaning effect and increasing the work efficiency. The chip recovery box 210 is detachably disposed inside the chip recovery chamber 111 to prevent chips and cutting agents from accumulating inside the chip recovery chamber 111 and being difficult to clean, thereby ensuring that the recovered chips are cleaned promptly and effectively.
[0031] In this embodiment, the debris suction member includes a dust hood 220 and a fan 230. The fan 230 is installed on the dust hood 220. The dust hood 220 is connected to the inner top wall of the debris recovery chamber 111. Specifically, a bracket 240 is connected to the dust hood 220, and the bracket 240 is connected to the inner top wall of the debris recovery chamber 111. The dust hood 220 is tilted upward so that it is horizontally arranged with the debris guide plate 130. Among them, starting the fan 230 increases the pressure inside the debris recovery chamber 111, thereby ensuring that the external debris is sucked into the debris recovery chamber 111 in cooperation with the debris guide plate 130, thereby improving the debris cleaning effect.
[0032] In the present embodiment, a filter screen 250 is detachably provided inside the debris recovery box 210. Specifically, a first handle is also installed on the outer wall of the debris recovery box 210. The debris recovery box 210 is divided into a first cavity 270 at the upper part and a second cavity 260 at the lower part by the filter screen 250. A limit plate 290 is installed on the inner wall of the debris recovery box 210, and the filter screen 250 falls on the limit plate 290. Specifically, a second handle can also be installed on the filter screen 250 to facilitate the removal of the filter screen 250 from the inside of the debris recovery box 210. A pull-out opening is provided on the bottom side wall of the debris recovery chamber 111, and the debris recovery box 210 is detachably provided inside the debris recovery chamber 111 through the pull-out opening. A slider 280 is fixedly connected to the bottom of the debris recovery box 210, and a slide groove matching the slider 280 is provided on the inner bottom wall of the debris recovery chamber 111. Among them, when the debris recovery box 210 is located inside the debris recovery chamber 111, the collected debris and cutting agent will first be filtered through the filter 250. At this time, the cutting agent will be filtered through the filter 250 and enter the second cavity 260. The debris is not filtered and is still located on the filter 250 inside the first cavity 270. At this time, the recovered debris can be directly separated from the solid and liquid, which is convenient for subsequent processing. When cleaning the debris and cutting agent, the debris recovery box 210 is pulled out from the debris recovery chamber 111, and then the filter 250 is taken out from the debris recovery box 210. The metal debris is processed, and then the cutting agent at the bottom is processed and poured out.
[0033] See also Figure 1 , Figure 2 and Figure 5 The limit baffle assembly 30 is installed on the side wall of the bed 110 and is tightly against the outer wall of the debris recovery box 210. The limit baffle assembly 30 can limit the debris recovery box 210, so that the debris recovery box 210 is more stable inside the debris recovery chamber 111.
[0034] In this embodiment, the limit baffle assembly 30 includes a rotating plate 310, which is rotatably connected to a pin shaft 340, which is fixedly connected to the bed 110, and a spring 320 is connected to the top of the rotating plate 310 near the side of the debris recovery box 210, and the other end of the spring 320 is connected to a close contact plate 330, which is close to the side wall of the debris recovery box 210. When the debris recovery box 210 is inside the debris recovery chamber 111, the rotating plate 310 is moved to rotate the rotating plate 310 upward and be arranged horizontally with the debris recovery box 210. At this time, the close contact plate 330 contacts the outer wall of the debris recovery box 210. Under the action of the spring 320, the close contact plate 330 can be close to the debris recovery box 210 to limit the position of the debris recovery box 210. When pulling out the debris recovery box 210, the rotating plate 310 is rotated again so that the rotating plate 310 is vertically arranged with the side wall of the debris recovery box 210, so that the abutting plate 330 leaves the side wall of the debris recovery box 210, and the debris recovery box 210 can be pulled out.
[0035] Working principle of the chip removal component of the CNC machine tool:
[0036] When the cutting device 120 is cutting the workpiece, the generated debris and cutting agent will enter the debris recovery chamber 111 along with the debris guide plate 130. When cutting, the chip suction piece is started, and the chip suction piece can increase the pressure inside the debris recovery chamber 111, so as to ensure that the debris and cutting agent generated by cutting can fall into the debris recovery chamber 111. When the debris enters the debris recovery chamber 111, it will fall into the debris recovery box 210 again. Through the cooperation of the chip suction piece and the debris guide plate 130, the debris and contaminated cutting agent generated by the cutting device 120 during cutting can be collected into the debris recovery box 210, so as to improve the cleaning effect of the debris, and the debris can be recovered after cutting once, so as to improve the cleaning effect and increase the work efficiency. The debris recovery box 210 is detachably arranged inside the debris recovery chamber 111, so as to prevent the debris and cutting agent from accumulating inside the debris recovery chamber 111 and being difficult to clean, so as to ensure the timely and effective cleaning of the recovered debris. The debris recovery box 210 can be limited and blocked by the limiting baffle assembly 30 , so that the debris recovery box 210 is more stable inside the debris recovery chamber 111 .
[0037] It should be noted that the specific model and specifications of the fan 230 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
[0038] The power supply and principle of the fan 230 are clear to those skilled in the art and will not be described in detail here.
