Description

Technical Field

[0001] This invention relates to the field of CNC grinding center technology, specifically to a CNC grinding center for easy cleaning. Background Technology

[0002] When grinding the surface of a workpiece using high-speed rotating grinding wheels or other abrasive tools, a lot of grinding debris, dust and other waste are generated in the workspace. This not only hinders the normal grinding process, but also makes the subsequent cleaning of grinding waste extremely difficult.

[0003] In existing technologies, CNC grinding centers often use protective covers to prevent grinding chips and dust from splashing. However, the chips inside the protective cover accumulate over time and require manual cleaning. When cleaning impurities manually, fine dust may remain and is difficult to remove completely, affecting the machining effect of the CNC center.

[0004] However, in actual use, the machining seat under the protective cover of the CNC grinding center generates a lot of fine dust when grinding the workpiece. The dust collection mechanism has difficulty in completely cleaning the dust that flies directly and adheres to the corners and grooves of the machining table.

[0005] Therefore, we need a CNC grinding center with an easy-to-clean machining table to solve the problem that existing CNC grinding centers cannot effectively handle fine dust, and to handle fine dust. Summary of the Invention

[0020] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other. Example

[0021] Please see Figures 1 to 11 This invention provides a technical solution: a CNC grinding center for easy cleaning, comprising a CNC grinding machine 1, a grinding assembly 11 mounted on the upper part of the CNC grinding machine 1, a machining cavity seat 12 provided at the upper end of the CNC grinding machine 1, the outer surface of the upper end of the telescopic machining cavity seat 12 being set at an inclined angle, grinding dust treatment mechanisms 2 respectively provided on the outer surfaces of both sides of the machining cavity seat 12, and a slag recovery mechanism 3 provided at the bottom of the inner cavity of the CNC grinding machine 1; the grinding dust treatment mechanism 2 includes a solid impurity filtration unit and a dust collection unit, the dust collection unit being located above the solid impurity filtration unit; the slag recovery mechanism 3 includes a centrifugal slag shaking unit and a collection unit, the collection units being located on both sides of the centrifugal slag shaking unit.

[0022] With the solid impurity filtration unit, solid impurities present in the dust are blocked and filtered in advance to prevent them from entering the dust collection cylinder and causing impact damage to internal components. The dust collection unit effectively ensures the dust collection of fine dust, solving the problem that existing CNC grinding centers cannot effectively handle fine dust. Example

[0023] See attached document Figures 1 to 11 Based on Embodiment 1, this embodiment adds a grinding dust treatment mechanism 2: The solid impurity filtration unit includes a fixed bracket 211, which is fixedly installed on the upper edge surface of the CNC grinding machine 1. A dust collection cylinder 212 is fixedly installed on the lower inner side of the fixed bracket 211. One end of the dust collection cylinder 212 is connected to a dust inlet bend 2121, and the other end of the dust collection cylinder 212 away from the dust inlet bend 2121 is movably latched with a plug 213. Through the inclined bending design of the dust inlet bend 2121, dust can be effectively extracted and guided while preventing large particles of debris from directly entering the interior of the dust inlet bend 2121 and causing blockage at the port of the dust inlet bend 2121. A Y-shaped pull ring is fixedly installed on the outer surface of the plug 213, and a pull rod 214 is fixedly installed on the inner surface of the plug 213. The other end of the pull rod 214... A conical collecting inner bucket 2141 is fixedly connected to the end of the dust collection cylinder 212. Limiting sliders 2142 are fixedly added to the outer surfaces of both sides of the conical collecting inner bucket 2141, and the outer surfaces of the limiting sliders 2142 are slidably connected to the inner surfaces of the grooves preset in the inner wall of the dust collection cylinder 212. By setting a plug 213, one end of the dust collection cylinder 212 is sealed. Combined with the addition of the conical collecting inner bucket 2141, this first filters the dust and impurities introduced by the dust inlet bend 2121, ensuring that impurities are blocked and prevented from entering the interior of the dust collection cylinder 221, thus affecting the service life of the overall components and avoiding direct impact from hard objects. Through the cooperation of a Y-shaped pull ring and a pull rod 214, manually pulling the Y-shaped pull ring outwards will drive the conical collecting inner bucket 2141 to pull outwards as a whole. The conical collecting inner barrel 2141 slides at its upper limit on the inner wall of the chute, ensuring the stable pulling out of the conical collecting inner barrel 2141. This effectively and quickly extracts the pre-blocked solid impurities, facilitating daily maintenance and cleaning. The solid impurity filtration unit pre-blocks and filters solid impurities present in the dust, preventing them from entering the dust settling cylinder and causing damage to internal components. The dust settling unit effectively ensures the dust settling of fine dust. The dust settling unit includes a dust settling cylinder 221 and a liquid storage ring cylinder 225. The outer surface of the dust settling cylinder 221 is fixedly connected to the inner upper part of the fixed bracket 211. The lower end of the dust settling cylinder 221 is connected through a connecting pipe 2211 extending into the dust collection cylinder 212. The inner upper wall of the dust settling cylinder 221 has pre-set... The exhaust port and the output end of the connecting pipe 2211 are connected to a central straight pipe 2212. A blower 2213 is installed at the upper end of the central straight pipe 2212, and the upper outer surface of the blower 2213 is fixedly connected to the top surface of the inner cavity of the dust settling cylinder 221. A rotating connecting pipe 222 is rotatably connected to the top surface of the inner cavity of the dust settling cylinder 221. A water storage chamber 223 is located at the top position of the rotating connecting pipe 222 and the inner cavity of the dust settling cylinder 221. A hollow circular plate 224 is rotatably connected to the lower outer surface of the rotating connecting pipe 222. The lower inner wall of the hollow circular plate 224 is rotatably connected to the outer surface of the central straight pipe 2212. A rotating bent pipe 2241 and a water outlet plate 2242 are respectively connected through the outer surface of the hollow circular plate 224. A water outlet hole is pre-set on the lower inner wall of the water outlet plate 2242.By controlling the operation of the air pump 2213, the fine grinding dust is guided into the water storage chamber 223 through the connecting pipe 2211 and the central straight pipe 2212, ensuring effective drainage of the grinding dust. As attached Figure 6 As shown, with the air pump 2213 turned on, the air carrying grinding dust enters the interior of the hollow circular plate 224. The gas is evenly sprayed out through the rotating bend pipe 2241. The reason why the rotating bend pipe 2241 is set to an array arrangement structure that converges towards the center is to enhance the jetting effect of the sprayed airflow and ensure that the rotating bend pipe 2241 provides a reverse thrust to the water outlet plate 2242, thereby causing the hollow circular plate 224 to rotate as a whole and the dust-carrying gas to be evenly sprayed downwards. This further solves the problem that the existing CNC grinding center cannot effectively handle fine dust, and can handle fine dust. Example

[0024] See attached document Figures 1 to 11 Based on Example 2, this example adds a slag recycling mechanism 3: The collection unit includes a side slag collection tray 321 and a water filter frame 322. The side slag collection tray 321 is arranged on both sides of the arched filter plate 311, and a feed inlet 3211 is preset on the inner wall of the side of the side slag collection tray 321 closest to the arched filter plate 311. The outer surface of the water filter frame 322 is movably embedded with the inner wall of the side slag collection tray 321. As attached Figure 9 As shown, the arched filter plate 311 is set at the bottom of the inner cavity of the CNC grinding machine 1 to perform preliminary filtration of the debris generated by grinding the workpiece above. The reason for setting the arched filter plate 311 as an arched structure is to allow the debris to slide down more quickly. With the setting of the side slag collection tray plate 321 and the water filter frame plate 322, the debris and coolant can be separated, ensuring the concentrated collection of debris and facilitating cleaning. This further solves the problem that the existing CNC grinding center cannot effectively handle fine dust, and can handle fine dust. Example

[0025] See attached document Figure 1-11 Based on Example 2, a dust suppression unit is added to this example: The dust suppression unit also includes a liquid storage ring cylinder 225. The outer surface of the liquid storage ring cylinder 225 is fixedly connected to the inner surface of the dust suppression cylinder 221. A water guide pipe is provided on one inner wall of the liquid storage ring cylinder 225. A water outlet pipe 2251 is evenly added to the inner surface of the liquid storage ring cylinder 225. A drain pipe is fixedly connected to the lower inner wall of the liquid storage ring cylinder 225. The drain pipe penetrates the inner wall of the dust suppression cylinder 221 and extends to the interior of the mud and water ring plate added to the lower outer surface of the dust suppression cylinder 221.

[0026] At this time, with the air pump 2213 turned on, the air carrying grinding dust enters the interior of the hollow circular plate 224. The gas is evenly sprayed out through the rotating bend pipe 2241. The reason why the rotating bend pipe 2241 is set to an array arrangement that converges towards the center is to enhance the jetting effect of the sprayed air and ensure that the rotating bend pipe 2241 provides a reverse thrust to the water outlet plate 2242, thereby causing the hollow circular plate 224 to rotate as a whole. The dust-carrying gas is evenly sprayed downwards. With the addition of multiple sets of water outlet pipes 2251, the falling grinding dust is effectively suppressed, thereby preventing dust from directly entering the outside. This further solves the problem that the existing CNC grinding center cannot effectively handle fine dust, and can handle fine dust. Example

[0027] See attached document Figure 1-11 Based on Example 3, this example adds a centrifugal slag-shaking unit: The centrifugal slag shaking unit includes an arched filter plate 311 and a servo motor 312. The arched filter plate 311 is located at the bottom of the inner cavity of the CNC grinding machine 1 and is fixedly connected to the inner wall of the CNC grinding machine 1. The servo motor 312 is fixedly installed on the bottom surface of the inner cavity of the CNC grinding machine 1. A rotating shaft 313 is fixedly installed on the output shaft of the servo motor 312. A hinge rod 3131 and a hinge rod 3132 are respectively hinged to the outer surface of the upper end of the rotating shaft 313. Curved elastic telescopic strips 3133 are provided on the inner surfaces of the hinge rod 3131 and the hinge rod 3132. At this time, the servo motor 312 drives and controls the rotation of its output shaft as the central point of power transmission, which in turn drives the rotating shaft 313 to rotate. Under the action of centrifugal force and the elastic deformation of the curved elastic telescopic strip 3133, the included angle between the two hinge rods 3131 and 3132 changes continuously. This causes the hinge rods 3131 and 3132 to reciprocate to strike the lower end of the arched filter plate 311, accelerating the falling speed of the debris above the arched filter plate 311. This further solves the problem that existing CNC grinding centers cannot effectively handle fine dust, and can handle fine dust.

[0028] Example 6: Figure 1-11 As shown, based on Embodiment 3, this embodiment also provides a method for using a CNC grinding center on a machining table that is easy to clean, including the following steps: Step 1: By setting the plug 213, one end of the dust collection cylinder 212 is sealed. With the addition of the conical collection inner barrel 2141, the dust and impurities introduced by the dust inlet bend 2121 are filtered first, ensuring that the impurities are blocked and preventing them from entering the dust collection cylinder 221 and affecting the service life of the overall components. Direct impact from hard objects is avoided. Through the cooperation of the Y-shaped pull ring and the pull rod 214, the Y-shaped pull ring is manually pulled outward, thereby driving the conical collection inner barrel 2141 to be pulled outward as a whole. The conical collection inner barrel 2141 slides at the upper limit on the inner wall of the slide groove, ensuring the stable pull out of the conical collection inner barrel 2141 and quickly extracting the pre-blocked solid impurities. Step Two: As shown in the appendix Figure 6 As shown, when the air pump 2213 is turned on, the air carrying grinding dust enters the interior of the hollow circular plate 224. The gas is evenly sprayed out through the rotating bend pipe 2241. The reason why the rotating bend pipe 2241 is set to an array arrangement structure that converges towards the center is to enhance the jetting effect of the sprayed airflow and ensure that the rotating bend pipe 2241 provides a reverse thrust to the water outlet plate 2242, so that the hollow circular plate 224 rotates as a whole and the dust-carrying gas is evenly sprayed downwards. With the addition of multiple sets of water outlet pipes 2251, the falling grinding dust is effectively suppressed, thereby preventing dust from directly entering the outside. Step 3: As shown in the appendix Figure 9 As shown, an arched filter plate 311 is placed at the bottom of the inner cavity of the CNC grinding machine 1 to initially filter the debris generated by grinding the workpiece above. The reason for setting the arched filter plate 311 as an arched structure is to allow the debris to fall off more quickly. At this time, the servo motor 312 drives and controls the output shaft to rotate as the central hub of power transmission, thereby driving the rotating shaft 313 to rotate. Under the action of centrifugal force and the elastic deformation of the curved elastic telescopic strip 3133, the included angle between the two hinge rods 3131 and 3132 changes continuously, thereby causing the hinge rods 3131 and 3132 to reciprocate to strike the lower end of the arched filter plate 311, accelerating the falling speed of the debris above the arched filter plate 311. With the setting of the side slag collection tray plate 321 and the water filter frame plate 322, the debris is separated from the coolant and the debris is collected in a concentrated manner.
