Technical Field

[0001] This utility model relates to the field of chip removal technology for CNC lathes, specifically to a flipping chip removal structure for a chip removal groove in a CNC machine tool. Background Technology

[0002] A chip conveyor for CNC machine tools is a device used to collect and discharge chips and waste. It is designed to keep the work area clean and ensure the effective handling of chips. In order to solve the problems of traditional chip conveyor structures, a flip-over chip conveyor structure has been introduced. This structure includes a flip-over chip conveyor, which is usually installed under the worktable of the machine tool. The chip conveyor can be flipped periodically during the machining process to pour out chips and waste from the work area.

The motor drives the ball screw at the output end to move in a threaded connection with the moving column. The moving column moves in the groove opening, thereby driving the push plate located at the bottom of the groove frame to push towards the opening. The sliders at both ends of the push plate slide in the slide groove.

[0004] This patent solves the problem of poor material pushing effect of the existing chip removal structure of the chip removal groove of CNC machine tool. However, during the chip removal process of CNC machine tool, the traditional chip removal groove is inconvenient to disassemble and assemble, and its internal structure is complex, which makes cleaning and maintenance difficult, especially for the metal scrap accumulated at the bottom of the groove, which is difficult to completely remove.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a flipping chip removal structure for a chip removal groove in a CNC machine tool, including a base plate:

[0008] A chip removal groove assembly is movably provided at the top of the base plate;

[0009] The inner cavity of the chip removal groove assembly is movably connected to a disassembly and assembly mechanism;

[0010] The disassembly and assembly mechanism includes a second connecting column, which is movably connected to the inner cavity of the chip discharge groove assembly. One end of the second connecting column is fixedly connected to a third connecting shaft, and the end of the third connecting shaft away from the second connecting column is fixedly connected to a disassembly and assembly column. A bottom column is fixedly connected to the outer side of the third connecting shaft, and a third fixing column is fixedly connected to one end of the bottom column. A third connecting column is fixedly connected to one end of the third fixing column, and a fixing screw is movably connected to the inner cavity of the third connecting column. A fixing nut is fixedly connected to one end of the fixing screw.

[0011] Furthermore, a flipping mechanism is fixedly connected to the top of the base plate;

[0012] The flipping mechanism includes a fixed column, which is fixedly connected to the top of the base plate. A connecting column is movably connected to the inner cavity of the fixed column, and a flipping column is fixedly connected to the left end of the connecting column.

[0013] Furthermore, the flipping mechanism also includes a connecting shaft, which is fixedly connected to the end of the connecting column away from the flipping column. An active turntable is fixedly connected to the outer side of the connecting shaft, and a transmission belt is movably connected to the inner cavity of the active turntable.

[0014] Furthermore, the flipping mechanism also includes a passive turntable, which is movably connected to the inner cavity of the transmission belt away from the active turntable, and the inner cavity of the passive turntable is fixedly connected to a second connecting shaft.

[0015] Furthermore, the chip removal groove assembly includes a frame, which is fixedly connected to one end of the connecting shaft two. One end of the frame is fixedly connected to a fixing post two. Two fixing posts two are symmetrically arranged, and the inner cavities of the two symmetrically arranged fixing posts two are provided with threaded slots.

[0016] Furthermore, the bottom of the inner cavity of the chip discharge groove assembly is provided with an inclined guide surface, which cooperates with the disassembly and assembly mechanism to guide the chips to be discharged in a designated direction.

[0017] Furthermore, the threaded slot on the second fixed column engages with the fixed screw of the disassembly and assembly mechanism to form a detachable locking structure, which facilitates the disassembly and assembly of the chip removal groove assembly.

[0018] This utility model has the following beneficial effects:

[0019] I. This utility model is equipped with a disassembly and assembly mechanism. Through the cooperation of components such as connecting column II, connecting shaft III, and disassembly and assembly column, the disassembly and assembly mechanism can realize the positioning and fixing of relevant components in the chip removal groove assembly. At the same time, the setting of fixing screw and fixing nut, together with the threaded groove on fixing column II, makes the chip removal groove assembly easy to disassemble and assemble, and facilitates the cleaning, maintenance and component replacement inside the chip removal groove. The disassembly and assembly mechanism allows the bottom column at the bottom of the frame to be disassembled, which facilitates the cleaning of metal waste on the surface of the bottom column.

[0020] II. Based on the above-mentioned beneficial effects, a flipping mechanism is also provided. When it is necessary to flip the chip conveyor assembly, the operator acts on the flipping column, causing the connecting column one to rotate in the inner cavity of the fixed column one. The rotation of the connecting column one then causes other connected components to rotate together, realizing the flipping action of the chip conveyor assembly. When the connecting column one rotates, it causes the connecting shaft one to rotate synchronously. The connecting shaft one drives the active turntable to rotate. When the active turntable rotates, the transmission belt in its inner cavity moves along with it under the action of friction. The transmission belt transmits the power of the active turntable to the passive gripper connected to it, realizing the transmission and conversion of power. When the transmission belt moves, it drives the passive turntable to rotate. The connecting shaft two fixed in the inner cavity of the passive turntable rotates synchronously with the passive turntable. The connecting shaft two is fixedly connected to the chip conveyor assembly, thereby driving the chip conveyor assembly to rotate around the connecting shaft two, completing the flipping action of the chip conveyor assembly.

[0021] III. Based on the aforementioned beneficial effects, a chip removal groove assembly is also provided. During installation, after the frame is installed to the corresponding position via connecting shaft two, the threaded groove of fixing post two is aligned with the fixing screw of the disassembly and assembly mechanism. The two are then fastened by rotating the fixing nut. Disassembly is achieved by reversing the operation. After the machine tool generates chips, the chips fall into the inner cavity of the chip removal groove assembly. Due to the presence of the inclined guide surface, the chips slide in the designated direction along the slope of the inclined guide surface under the action of gravity. During the sliding process, they may interact with the bottom post of the disassembly and assembly mechanism, further guiding the chips to concentrate, and finally being discharged from the designated position of the chip removal groove. When it is necessary to install the chip removal groove assembly, the fixing screw is aligned with the threaded groove of fixing post two, and the fixing nut is rotated. Under the action of the thread, the fixing screw is gradually screwed into the groove of fixing post two until the chip removal groove assembly is firmly fixed. When it is necessary to disassemble, the fixing nut is rotated in the opposite direction to make the fixing screw exit the groove of fixing post two, thereby disassembling the chip removal groove assembly.

Detailed Implementation

[0030] 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.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figure 1-5 As shown, this utility model is a flipping chip removal structure for a chip removal groove of a CNC machine tool, including a base plate 1:

[0033] A chip removal groove assembly 3 is movably installed at the top of the base plate 1;

[0034] The inner cavity of the chip discharge groove assembly 3 is movably connected to a disassembly and assembly mechanism 4;

[0035] The disassembly and assembly mechanism 4 includes a second connecting column 401, which is movably connected to the inner cavity of the chip discharge groove assembly 3. One end of the second connecting column 401 is fixedly connected to a third connecting shaft 402. The end of the third connecting shaft 402 away from the second connecting column 401 is fixedly connected to a disassembly and assembly column 403. The outer side of the third connecting shaft 402 is fixedly connected to a bottom column 404. One end of the bottom column 404 is fixedly connected to a third fixing column 405. One end of the third fixing column 405 is fixedly connected to a third connecting column 406. The inner cavity of the third connecting column 406 is movably connected to a fixing screw 407. One end of the fixing screw 407 is fixedly connected to a fixing nut 408.

[0036] The disassembly and assembly mechanism 4, through the cooperation of components such as connecting column 2 401, connecting shaft 3 402, and disassembly and assembly column 403, can realize the positioning and fixing of relevant components in the chip removal groove assembly 3; at the same time, the setting of fixing screw 407 and fixing nut 408, in conjunction with the threaded groove on fixing column 2 302, makes the chip removal groove assembly 3 easy to disassemble and assemble, facilitating cleaning, maintenance and component replacement inside the chip removal groove. The disassembly and assembly mechanism 4 allows the bottom column 404 at the bottom end of the frame 301 to be disassembled, facilitating the cleaning of metal scrap on the surface of the bottom column 404.

[0037] A flipping mechanism 2 is fixedly connected to the top of the base plate 1;

[0038] The flipping mechanism 2 includes a fixed column 201, which is fixedly connected to the top of the base plate 1. A connecting column 202 is movably connected to the inner cavity of the fixed column 201, and a flipping column 203 is fixedly connected to the left end of the connecting column 202.

[0039] The fixed column 201 in the flipping mechanism 2 provides stable support for the connecting column 202. The connecting column 202 can move inside the fixed column 201. Together with the flipping column 203 on the left end, it provides a rotation basis for the subsequent flipping of the chip removal groove assembly 3, so that the chip removal groove can be flipped to a suitable angle for chip removal and improve chip removal efficiency.

[0040] The flipping mechanism 2 also includes a connecting shaft 204, which is fixedly connected to the end of the connecting column 202 away from the flipping column 203. The outer side of the connecting shaft 204 is fixedly connected to the drive turntable 205, and the inner cavity of the drive turntable 205 is movably connected to the transmission belt 206.

[0041] The connecting shaft 204 is fixed on the connecting column 202, and transmits the rotation of the connecting column 202 to the drive turntable 205. The drive turntable 205 cooperates with the transmission belt 206 to transmit and convert power, making the flipping action of the chip conveyor assembly 3 more stable and efficient. At the same time, the transmission ratio can be adjusted according to actual needs to meet different flipping speed requirements.

[0042] The flipping mechanism 2 also includes a passive turntable 207, which is movably connected to the inner cavity of the transmission belt 206 away from the active turntable 205. The inner cavity of the passive turntable 207 is fixedly connected to a connecting shaft 208.

[0043] The passive turntable 207 works in conjunction with the transmission belt 206 to further transmit the power transmitted by the active turntable 205 to the connecting shaft 208. The connecting shaft 208 is connected to the chip removal groove assembly 3, which realizes the transmission of power from the flipping mechanism 2 to the chip removal groove assembly 3, ensuring that the chip removal groove assembly 3 can flip stably and ensuring that the chip removal process proceeds smoothly.

[0044] Working principle: When installing the chip conveyor assembly 3, place the connecting post 401 of the disassembly mechanism 4 into the appropriate position inside the chip conveyor assembly 3, aligning the fixing screw 407 with the threaded slot on the fixing post 302. Rotate the fixing nut 408 to screw the fixing screw 407 into the slot of the fixing post 302, thus fastening the disassembly mechanism 4 to the chip conveyor assembly 3. For disassembly, rotate the fixing nut 408 in the opposite direction to disengage the fixing screw 407 from the slot of the fixing post 302, separating the disassembly mechanism 4 from the chip conveyor assembly 3. When it is necessary to flip the chip conveyor assembly 3, the operator applies the flipping post 203, causing the connecting post 202 to rotate inside the fixing post 201. The rotation of the connecting post 202 then drives other connected components to rotate together, achieving the flipping action of the chip conveyor assembly 3. When column 1 202 rotates, it drives connecting shaft 1 204 to rotate synchronously. Connecting shaft 1 204 drives active turntable 205 to rotate. When active turntable 205 rotates, the transmission belt 206 in its inner cavity moves under the action of friction. The transmission belt 206 transmits the power of active turntable 205 to the passive gripper connected to it, realizing the transmission and conversion of power. When the transmission belt 206 moves, it drives passive turntable 207 to rotate. Connecting shaft 2 208, which is fixed in the inner cavity of passive turntable 207, rotates synchronously with passive turntable 207. Connecting shaft 2 208 is fixedly connected to chip removal groove assembly 3, thereby driving chip removal groove assembly 3 to rotate around connecting shaft 2 208, completing the flipping action of chip removal groove assembly 3. The bottom column 404 at the bottom end of frame 301 can be disassembled through disassembly and assembly mechanism 4, which facilitates the cleaning of metal waste on the surface of bottom column 404.

[0045] In this step, the bottom post 404 at the bottom of the frame 301 can be disassembled through the disassembly and assembly mechanism 4, making it convenient to clean the metal scrap on the surface of the bottom post 404.

[0046] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes a chip removal groove assembly 3:

[0047] The chip removal groove assembly 3 includes a frame 301, which is fixedly connected to one end of the connecting shaft 208. A fixing post 302 is fixedly connected to one end of the frame 301. Two fixing posts 302 are symmetrically arranged, and the inner cavities of the two symmetrically arranged fixing posts 302 are provided with threaded slots.

[0048] The frame 301 is used to accommodate chips and is the main structure of the chip conveying groove assembly 3. The fixing columns 302 are symmetrically arranged and have threaded grooves in their inner cavities. They cooperate with the fixing screws 407 of the disassembly and assembly mechanism 4, which not only makes the chip conveying groove assembly 3 and the disassembly and assembly mechanism 4 firmly connected, but also facilitates the installation and disassembly of the chip conveying groove assembly 3, and makes it convenient to maintain and clean the chip conveying groove.

[0049] The bottom of the inner cavity of the chip discharge groove assembly 3 is provided with an inclined guide surface, which cooperates with the disassembly and assembly mechanism 4 to guide the chips to be discharged in a designated direction.

[0050] The inclined guide surface, in conjunction with the disassembly and assembly mechanism 4, can guide the chips to be discharged in a designated direction, preventing chips from accumulating in the chip discharge groove, improving chip discharge efficiency, ensuring a smooth chip discharge process, and reducing the impact of chips on machine tool operation.

[0051] The threaded slot on the fixed column 302 engages with the fixed screw 407 of the disassembly and assembly mechanism 4 to form a detachable locking structure, which facilitates the disassembly and assembly of the chip discharge groove assembly 3.

[0052] The threaded slot on the fixed column 302 engages with the fixed screw 407 of the disassembly and assembly mechanism 4 to form a detachable locking structure, which greatly facilitates the disassembly and assembly of the chip conveyor assembly 3. When it is necessary to clean the chip conveyor, replace parts, or repair the machine tool, the chip conveyor assembly 3 can be quickly disassembled, improving the efficiency of maintenance work.

[0053] Working principle: During installation, after the frame 301 is installed in the corresponding position via the connecting shaft 208, the threaded groove of the fixing post 302 is aligned with the fixing screw 407 of the disassembly and assembly mechanism 4. The two are then fastened by rotating the fixing nut 408. Disassembly is achieved by reversing the operation. After the machine tool generates chips, the chips fall into the inner cavity of the chip discharge groove assembly 3. Due to the presence of the inclined guide surface, the chips slide in the specified direction along the slope of the inclined guide surface under the action of gravity. During the sliding process, they may come into contact with the disassembly and assembly mechanism 4. The interaction between the base post 404 further guides the chips to concentrate and finally discharge them from the designated position in the chip removal groove. When it is necessary to install the chip removal groove assembly 3, align the fixing screw 407 with the threaded groove of the fixing post 302 and rotate the fixing nut 408. Under the action of the thread, the fixing screw 407 gradually screws into the groove of the fixing post 302 until the chip removal groove assembly 3 is firmly fixed. When it is necessary to disassemble, rotate the fixing nut 408 in the opposite direction to make the fixing screw 407 exit the groove of the fixing post 302, thereby realizing the disassembly of the chip removal groove assembly 3.
