Description

Technical Field

[0001] The invention relates to the technical field of machine tool chip and debris collection, and in particular to a cutting device based on a numerically controlled machine tool. Background Art

[0002] When a workpiece is cut by a CNC machine tool, debris will be generated. The collection and treatment of the debris generated during the cutting process is an important part of ensuring the operating efficiency of the machine tool, extending the service life of the tool, and maintaining a safe working environment. During the cutting process, coolant needs to be sprayed on the workpiece. A large amount of coolant will exist in the collected debris, and the debris and coolant need to be separated.

[0003] The patent document with the authorization announcement number CN118123575B discloses a metal cutting machine tool for collecting metal chips, comprising a fixed frame, a bottom outer wall of the fixed frame is fixedly connected with a support foot, a top outer wall of the fixed frame is provided with a first groove, an inner wall of the first groove is provided with a first through hole, a left outer wall of the fixed frame is fixedly connected with a first motor, an output end of the first motor is slidably connected with a third sliding block, a back of the fixed frame is fixedly connected with a first connecting rod, and a front of the fixed frame is fixedly connected with a second connecting rod;

[0004] The metal cutting machine provided by the patent document separates the iron chips and coolant through a separation device when collecting iron chips after cutting. After separation, the iron chips are spun dry by a third motor to discharge the residual coolant. The discharged iron chips are collected in a separation box.

[0005] In different metal cutting processing methods, the shapes of the debris produced are different. When the separation box is driven to rotate, some long strips of debris are easily stuck in the filter holes of the separation box. It is difficult to completely remove the debris in the filter holes of the separation box by rotating the cleaning roller against the side wall of the separation box. On the contrary, the debris may be squeezed and deformed and stuck in the filter holes, blocking the filter holes, increasing the difficulty of separating the debris from the filter holes, making it difficult to completely clean the debris in the filter holes, and affecting the relative separation effect of the debris and the coolant in long-term use. In addition, the debris produced by cutting is relatively loose and occupies a large space, making it easy to fill up the space in the separation box, resulting in a limited amount of debris that can be processed by the separation box at a single time and low processing efficiency. Summary of the invention

[0036] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] like Figure 1 As shown, the cutting device based on a CNC machine tool of the present invention includes a clamping mechanism 11, a tool holder mechanism 12 and a separation mechanism. The tool holder mechanism 12 is used to clamp the cutting tool. The workpiece to be processed is fixed on the clamping mechanism 11. A control module is provided on the machine tool 1. The control module is used to control the rotation and movement of the clamping mechanism 11 and the tool holder mechanism 12 so that the tool cuts the workpiece according to the processing requirements. The debris generated during the cutting process enters the separation mechanism, and the separation mechanism further separates the debris and the coolant.

[0038] like Figures 2 to 5 As shown, the separation mechanism includes a separation box 2, a movable plate 21, a baffle plate 23, a separation plate 22 and a push assembly. The upper end of the separation box 2 is an open end. The open end of the separation box 2 is opposite to the operating position of the cutting process on the machine tool 1, that is, it is longitudinally opposite to the clamping mechanism 11 and the tool holder mechanism 12, so that when the tool performs cutting process on the workpiece, the debris generated can smoothly fall into the separation box 2 from the open end of the separation box 2. The movable plate 21, the baffle plate 23 and the separation plate 22 are all arranged inside the separation box 2. The movable plate 21 and the baffle plate 23 are connected to the separation box 2. The plates 23 are all rectangular plates. The two opposite longitudinal sides of the movable plate 21 slide against the inner wall of the separation box 2. The side of the bottom of the movable plate 21 rotates relative to the separation box 2. The separation box 2 is also provided with a driving member 211. The driving member 211 can be a motor. The driving end of the driving member 211 is connected to the bottom of the movable plate 21. The driving member 211 is used to drive the movable plate 21 to rotate around its bottom side, with the side opposite to the baffle 23 and the movable plate 21 as the inner side, and a feed port for receiving debris is formed between the baffle 23 and the movable plate 21.

[0039] The separation plate 22 is arranged horizontally on the lower side of the separation box 2. The separation plate 22 is located at the lower side of the movable plate 21 and the baffle 23. The height of the separation plate 22 decreases in the direction away from the movable plate 21. There is a gap between the lower end of the separation plate 22 and the side wall of the separation box 2. The upper end surface of the separation plate 22 is evenly spaced along its inclined direction to provide a plurality of upwardly protruding separation portions 221. The separation portions 221 are in the shape of long strips. A strip groove for accommodating debris is formed between any two adjacent separation portions 221. There is a gap between the upper end surface of the separation plate 22 and the bottom side of the baffle 23. The debris enters the separation box 2 from between the baffle plate 23 and the movable plate 21 and falls on the separation plate 22. Under the action of the separation portion 221, the debris will not slide along the separation plate 22. The debris that first falls on the separation plate 22 accumulates in the strip groove. The coolant flows along the inclined direction of the separation plate 22 and enters the space at the bottom of the separation box 2 through the gap between the separation plate 22 and the separation box 2. A liquid outlet 28 is also provided at the bottom of the separation box 2. The coolant further flows out and is collected through the liquid outlet 28. The collected coolant can be recycled after treatment.

[0040] As the amount of debris accumulated between the movable plate 21 and the baffle 23 increases, the driving member 211 can be turned on and the movable plate 21 can be driven by the driving member 211 to rotate in a direction close to the baffle 23 to squeeze the loose debris, reduce the space occupied by the debris, and increase the storage capacity of the debris. After the loose debris is squeezed, the gap between the debris is reduced. When the machine tool 1 works again, the squeezed debris can better intercept more debris, facilitating the separation of the debris and the coolant.

[0041] The separation box 2 is also provided with a discharge port 27 at the bottom, and a cover plate can be provided at the discharge port 27, and the cover plate can be detachably connected to the discharge port 27. When the debris is accumulated enough, the debris can be discharged from the discharge port 27 of the separation box 2 by cooperating with the push assembly and the movable plate 21. The push assembly includes a cylinder 261 and a push plate 26. The push plate 26 is movably connected to the separation box 2. The cylinder 261 is installed on the separation box 2. The protruding end of the cylinder 261 is fixed relative to the push plate 26. The cylinder 261 pushes the push plate 26 to move in the horizontal direction. The separation plate 22 is connected to the bottom of the separation box 2 by an elastic telescopic rod 222. When the separation plate 22 is subjected to longitudinal pressure, it moves downward and squeezes the elastic telescopic rod 222. During the discharging operation, the driving member 211 first pushes the movable plate 21 to rotate to a horizontal state in a direction close to the baffle 23. The debris is fully squeezed between the movable plate 21 and the separation plate 22. When the movable plate 21 rotates to a horizontal state, as shown in FIG. Figure 4 and Figure 5As shown, the separation plate 22 is squeezed and moved down to the lower side of the push plate 26 until the squeezed debris is opposite to the discharge port 27. The cylinder 261 works and pushes the debris block to slide against the separation plate 22 and the movable plate 21 through the push plate 26 until the material is discharged through the discharge port 27. During the sliding process of the debris block relative to the separation plate 22 and the movable plate 21, the debris in the strip groove on the separation plate 22 can also be brought out, effectively reducing the residue of debris on the separation plate 22.

[0042] In different cutting operations, the range of chip falling varies due to the influence of the relative rotation speed of the workpiece and the tool during the cutting process, as well as the cutting method. When the workpiece rotation speed is high, the chips generated by the cutting are subjected to a greater centrifugal force. In order to allow the chips to fall smoothly between the movable plate 21 and the baffle 23, an adjustment component is also provided on the separation box 2. The baffle 23 slides with the separation box 2. The adjustment component is used to adjust the distance between the baffle 23 and the movable plate 21, so as to flexibly adjust the material receiving range formed by the baffle 23 and the movable plate 21 according to the difference in the workpiece rotation speed during the cutting operation.

[0043] like Figure 2 and Figure 3 As shown, the adjustment assembly includes a rack 1 31, a rack 2 32, a gear 3 and a connecting piece 311. The rack 1 31 and the rack 2 32 are both slidably matched with the separation box 2 in the horizontal direction. The tooth ends of the rack 1 31 and the rack 2 32 are opposite to each other. The gear 3 is rotatably installed on the separation box 2. The rack 1 31 and the rack 2 32 are meshed with the gear 3 at the same time. The connecting piece 311 is fixed to the rack 1 31. An arc-shaped guide groove 24 is provided on the separation box 2. When the movable plate 21 is in a vertical state, the guide groove 24 is located on the outer side of the movable plate 21. The movable plate 21 is connected to the guide groove 24 through a guide block. The guide block passes through the guide groove 24 and is connected to the guide groove 24. The guide block is elastically connected to the movable plate 21 by sliding cooperation, and the guide block extends through the guide groove 24 to the outside of the separation box 2 and movably abuts against the connecting piece 311. When the driving piece 211 drives the movable plate 21 to rotate outward, the movable plate 21 pushes the connecting piece 311 to slide through the guide block, and the connecting piece 311 further drives the rack 1 31 to slide. Under the transmission action of the gear 3, the rack 2 32 slides in the opposite direction to the rack 1 31, and the rack 2 32 pushes the baffle 23 to move away from the movable plate 21, so that the material receiving range formed between the movable plate 21 and the baffle 23 is increased, which facilitates the debris to fall smoothly between the movable plate 21 and the baffle 23.

[0044] Among them, a connecting groove is provided at the position where the movable plate 21 is used to connect the guide block. The guide block and the connecting groove are connected by a spring, and the guide block and the connecting groove are slidably matched. The inner end face of the guide block is an inclined surface. After the movable plate 21 is rotated to a vertical state, the inner end face of the guide block abuts against the inner end of the guide groove 24. When the driving member 211 continues to drive the movable plate 21 to rotate inward, the guide block is squeezed, disengaged from the relative guide groove 24, and enters the connecting groove, so that the movable plate 21 can smoothly fit the inner wall of the separation box 2 and rotate inward. When the movable plate 21 rotates outward until the guide block is opposite to the guide groove 24, the guide block re-extends into the guide groove 24 under the elastic force of the spring.

[0045] like Figure 6 As shown, in order to squeeze the loose debris in time during the debris collection process and improve the squeezing effect of the loose debris, a driving assembly can also be set on the separation box 2, and the driving assembly is used to drive the baffle 23 to rotate around its upper side and squeeze the debris between the baffle 23 and the movable plate 21. The driving assembly includes a cylinder 1 4, a driving wheel 41 and a rack 3 42. A moving part 25 is also provided on the separation box 2. The top side of the baffle 23 rotates with the moving part 25, the moving part 25 slides with the separation box 2, the moving part 25 is fixed with the rack 2 32, a cavity is formed inside the moving part 25, the rack 3 42 is longitudinally fixed in the moving part 25, the driving wheel 41 and the moving part 25 are lifted and lowered, the driving wheel 41 is meshed with the rack 3 42, the baffle 23 is fixed relative to the driving wheel 41, and the cylinder 1 4 is installed on the outer wall of the separation box 2 On the top, the protruding end of the cylinder 4 is rotated and cooperates with the driving wheel 41. When the cylinder 4 drives the driving wheel 41 to rise and fall, the driving wheel 41 rotates under the meshing action with the rack three 42, and drives the baffle 23 to rotate around its top side. During operation, as the accumulation of debris increases, the cylinder 4 drives the driving wheel 41 downward, and while the driving wheel 41 moves downward, it drives the baffle 23 to rotate in the direction close to the movable plate 21, that is, the baffle 23 rotates around its top side in the direction close to the movable plate 21 to squeeze the debris, and also has the action of moving downward at the same time, to avoid the problem that when the baffle 23 rotates, the gap between its bottom side and the separation plate 22 becomes larger, and the debris slips from between the baffle 23 and the separation plate 22. In addition, the baffle 23 is driven by the drive assembly to rotate and squeeze the loose debris, which will not affect the material receiving operation of the separation box 2.

[0046] The cutting device based on a numerically controlled machine tool provided by the present invention is convenient for collecting and separating the debris and coolant in the cutting process, and timely extruding the loose debris, thereby increasing the capacity for debris collection and improving the work efficiency of debris processing.
