Description

Technical Field

[0001] This invention relates to the field of CNC machine tool protection technology, specifically to a flip-type protective device for CNC machine tools and its usage method. Background Technology

[0002] In modern manufacturing, CNC machine tools, as core processing equipment, are widely used in aerospace, automobile manufacturing, machining and many other fields due to their high precision, high efficiency and high automation. During the operation of CNC machine tools, the cutting tools, workpieces and other parts rotate or move at high speed. If the operator accidentally touches them, it may cause serious mechanical injury. Protective devices such as protective doors and guardrails can isolate the operator from the danger zone and prevent the body from direct contact with moving parts, thereby reducing the risk of accidents. At the same time, during the processing, high-temperature chips, coolant and other substances are generated, which may splash and burn the operator. Protective devices can block these high-temperature substances and protect the operator's skin and eyes. Among them, the flip-type protective device is a commonly used protective device for CNC machine tools. It is installed in a flip-type manner through a hinge. It can be opened or closed in a short time, improving work efficiency. Compared with the traditional side-pushing protective door, the flip-type protective door does not require a large lateral movement space, and is especially suitable for working environments with limited space.

[0003] Existing tilting protective devices for CNC machine tools require manual control by the operator to tilt the protective cover. During prolonged work or when the device needs to be frequently turned on and off, operators may become fatigued. Furthermore, improper operation or lack of concentration during manual tilting can result in the protective device not being fully closed or secured, posing a safety hazard. Additionally, the protective device is typically integrated with the machine tool, making it difficult to disassemble and perform maintenance and cleaning. Therefore, improvements are needed.

[0004] Based on this, the present invention designs a flip-type protective device for CNC machine tools and its usage method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a flip-type protective device for CNC machine tools and its usage method, in order to solve the problems mentioned in the background art. Existing flip-type protective devices for CNC machine tools require manual control of the protective cover to flip during use. Under conditions of long-term work or frequent opening and closing of the protective device, the operator may feel fatigued. At the same time, if the operator operates improperly or is not focused during manual flipping, the protective device may not be completely closed or fixed, thus posing a safety hazard. In addition, the protective device is generally designed as an integral part of the machine tool, making it difficult to disassemble the protective device and the machine tool for inspection, maintenance and cleaning.

[0008] As a further embodiment of the present invention, the protective mechanism includes a protective frame, an end plate is fixedly installed on one side inside the protective frame, a fixing slot is symmetrically provided at the center of the surface of the end plate, and the fixing slot corresponds to the position of the trapezoidal block, universal wheels are fixedly installed at the four corners of the bottom of the protective frame, and two T-shaped limiting strips are fixedly installed on both sides of the inner wall of the protective frame, the T-shaped limiting strips correspond to the position of the T-shaped limiting groove and have the same shape.

[0009] As a further embodiment of the present invention, a plurality of movable rollers are fixedly installed at equal intervals between the two T-shaped limiting inserts on the inner wall of the protective frame, and the movable rollers correspond to the positions of the strip-shaped roller grooves. The top of the protective frame is provided with a storage groove, which has the same shape as the arc-shaped protective cover, and the arc-shaped protective cover is slidably connected to the inside of the storage groove. The top of both sides of the inside of the protective frame is symmetrically provided with arc-shaped sliding grooves, and the arc-shaped sliding grooves are connected to the storage grooves. The movable rollers are slidably connected to the inside of the arc-shaped sliding grooves. Fixed buckles are fixedly installed at both ends of the top of the inside of the protective frame.

[0010] As a further embodiment of the present invention, the rebound reset mechanism includes a first mounting block, which is fixedly connected to the arc-shaped protective cover. An arc-shaped mounting rod is fixedly mounted on one side of the first mounting block, and an end block is fixedly mounted on the end of the arc-shaped mounting rod away from the first mounting block. A second mounting block is slidably mounted through the surface of the arc-shaped mounting rod, and the second mounting block is fixedly connected to the inner wall of the protective frame. An arc-shaped reset spring is provided on the surface of the arc-shaped mounting rod located between the first mounting block and the second mounting block.

[0011] As a further embodiment of the present invention, the bottom of both ends of the mounting frame is symmetrically provided with limiting grooves, and the two ends of the mounting frame are symmetrically provided with connecting slots, and the positions of the connecting slots and the fixing buckles are corresponding. Fixing blocks are fixedly installed on both sides inside the mounting frame, and an electric push rod II is fixedly installed on one side of the fixing block. A movable seat is fixedly installed on the end of the electric push rod II away from the fixing block.

[0012] As a further embodiment of the present invention, limiting protrusions are fixedly installed on both sides of the movable seat, and the limiting protrusions are slidably connected to the inside of the limiting groove. A rotating top frame is rotatably installed on the top of the movable seat via a pin. A connecting frame is rotatably installed on the end of the rotating top frame away from the movable seat via a pin. A cleaning brush is fixedly installed on the top of the two connecting frames, and the cleaning brush is slidably connected to the top of the mounting frame.

[0013] A method of using a tilting protective device for CNC machine tools, the method comprising the following steps: Push the protective frame to one side of the machine tool, so that the T-shaped limiting strip and moving roller on the inner wall of the protective frame correspond to the T-shaped limiting groove and strip groove on both sides of the machine tool. Push the protective frame to cover the surface of the machine tool, so that the T-shaped limiting strip and moving roller are inserted into the corresponding T-shaped limiting groove and strip groove until the end plate contacts the trapezoidal block. Continue to push the end plate to press against the machine tool, so that the end plate squeezes the trapezoidal block and lifts the trapezoidal block close to the mounting plate. The trapezoidal block pushes the connecting rod to drive the limiting plate to slide inside the mounting groove, squeezing the clamping spring to deform, until the end plate is pressed against the machine tool, so that the fixed groove corresponds to the position of the trapezoidal block. Under the rebound of the clamping spring, the limiting plate is lifted, and the connecting rod is driven to lift the trapezoidal block away from the mounting plate, so that the trapezoidal block is inserted into the corresponding fixed groove, thereby clamping and fixing the protective frame to the surface of the machine tool. Control the extension of two electric push rods, so that the top of the electric push rod lifts the rotating seat, causing the arc-shaped protective cover to rotate and retract into the storage slot. This causes the arc-shaped protective cover to move the mounting block one closer to the mounting block two, squeezing the arc-shaped return spring to deform on the surface of the arc-shaped mounting rod until the arc-shaped protective cover is retracted into the storage slot. Then, lift the mounting frame and align the connecting slots on both sides of the mounting frame with the fixing buckles. Insert the fixing buckles into the corresponding connecting slots and clamp the mounting frame between the two fixing buckles. Before the machine tool starts processing, control the electric push rod one to retract and rotate between rotating seat one and rotating seat two, pull the rectangular baffle to rotate on one side of the protective frame, and pull the arc-shaped protective cover out from the storage slot. At the same time, the arc-shaped return spring rebounds between mounting block one and mounting block two, so that the arc-shaped protective cover returns to its original position and covers the processing position of the machine tool. After the rectangular baffle rotates to close to the protective frame, control the machine tool to start processing. After the machining is completed, the machining machine is stopped, the fixed block is retracted, and the movable seat is moved to both ends of the mounting frame. The rotating top frame on the top of the movable seat is lifted and rotated, so that the two rotating top frames lift the cleaning brush until the cleaning brush is lifted and pressed against the surface of the arc-shaped protective cover. At the same time, the electric push rod is extended to lift the rectangular baffle and drive the arc-shaped protective cover into the storage groove, so that the arc-shaped protective cover slides at the bottom of the cleaning brush to clean the waste chips and coolant that splashed and adhered to the inner wall of the arc-shaped protective cover during the machining process.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a protective frame, a storage slot, an arc-shaped protective cover, an electric push rod, and an arc-shaped return spring, allows the electric push rod to extend after machining on a machine tool. The top of the electric push rod lifts a rectangular baffle, pushing the arc-shaped protective cover to rotate on top of the protective frame, causing it to rotate and retract into the storage slot. Simultaneously, as the arc-shaped protective cover rotates on top of the protective frame, it drives mounting block one to slide an arc-shaped mounting rod inside mounting block two. This causes mounting block one to rotate closer to mounting block two, compressing the arc-shaped return spring and deforming it on the surface of the arc-shaped mounting rod. This process then allows the machined part to be placed back into the storage slot. After removing the unprocessed part from the machining position of the machine tool, control the electric push rod one to retract, pull the rectangular baffle to rotate on the top of the protective frame, and pull the arc-shaped protective cover out of the storage slot. At the same time, under the rebound action of the arc-shaped return spring, push the mounting block one away from the mounting block two, and apply a thrust to the arc-shaped protective cover to pull out of the storage slot, ensuring that there is no jamming when the arc-shaped protective cover is pulled out from the inside of the storage slot. This makes it easy to control the arc-shaped protective cover and the rectangular baffle to open or close on the surface of the protective frame, to shield and protect the machine tool, and prevent the waste chips and coolant generated by the machine tool from splashing everywhere.

[0015] 2. This invention, by setting up a machine tool, a protective frame, an end plate, a trapezoidal locking block, and a clamping spring, pushes the protective frame closer to the machine tool, aligning the T-shaped limiting strip on the inner wall of the protective frame with the T-shaped limiting groove until the T-shaped limiting strip is inserted into the corresponding T-shaped limiting groove. Simultaneously, a moving roller rolls inside the corresponding strip groove, covering the processing position of the machine tool. At the same time, the end plate gradually approaches the trapezoidal locking block, pushing and squeezing the trapezoidal locking block closer to the mounting plate, causing the connecting rod to slide inside the mounting groove. This causes the clamping spring to be squeezed and deformed inside the mounting groove until the end plate is pressed tightly against one side of the machine tool, aligning the fixed locking groove with the trapezoidal locking block. Under the rebound action of the clamping spring, the limiting plate is lifted and slides inside the mounting groove, causing the connecting rod to push out of the mounting groove and push the trapezoidal locking block into the corresponding fixed locking groove. This secures the end plate tightly against one side of the machine tool, facilitating the disassembly, cleaning, or installation of the protective mechanism and the machine tool.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-10 The present invention provides a technical solution: A flip-type protective device for CNC machine tools includes a machine tool 1. T-shaped limiting grooves 101 are symmetrically arranged on both sides of the machine tool 1. A strip-shaped roller groove 102 is located at the center between the two T-shaped limiting grooves 101 on both sides of the machine tool 1. An mounting plate 2 is fixedly installed at the center of one side of the machine tool 1. A protective mechanism 3 is slidably installed on the surface of the machine tool 1. An arc-shaped protective cover 4 is slidably installed on the top of the protective mechanism 3. A rectangular baffle 401 is fixedly installed on one side of the arc-shaped protective cover 4. Multiple moving rollers 402 are fixedly installed on both sides of the arc-shaped protective cover 4. An electric push rod 5 is fixedly installed on one side of the protective mechanism 3. A rotating seat 501 is rotatably installed at the top of the electric push rod 5 via a pin, and the rotating seat 501 is fixedly connected to the rectangular baffle 401. A rotating seat 502 is rotatably installed at the bottom of the electric push rod 5 via a pin. Springback reset mechanisms 6 are symmetrically arranged on both sides of the top of the protective mechanism 3. A mounting bracket 7 is located at the center of the top of the protective mechanism 3. During operation, the protective mechanism 3 is pushed close to the machine tool 1, covering the surface of the machining position on the machine tool 1. The protective mechanism 3 is then secured in place by the mounting plate 2, ensuring it is firmly fixed at the machining position on the machine tool 1. The electric push rod 5 is then extended, rotating between the rotating seat 501 and the rotating seat 502. This causes the arc-shaped protective cover 4 to rotate and open at the top inside the protective mechanism 3, deforming the springback reset mechanism 6 at the top inside the protective mechanism 3. This lifts the mounting bracket 7, which then locks into place at the top inside the protective mechanism 3. After the part is fixed at the machining position on the machine tool 1, the control... The electric push rod 5 retracts, causing it to rotate between the rotating seat 501 and the rotating seat 502, pulling the arc-shaped protective cover 4 to rotate at the top inside the protective mechanism 3. At the same time, the springback reset mechanism 6 springs back and applies elastic force to the arc-shaped protective cover 4 to assist in its reset until the arc-shaped protective cover 4 covers and closes the top of the protective mechanism 3. The machine tool 1 is then controlled to start processing. After processing is completed, the arc-shaped protective cover 4 is controlled to rotate at the top inside the protective mechanism 3 to open, allowing the inner wall of the arc-shaped protective cover 4 to slide past the top of the mounting bracket 7 to clean the inner wall of the arc-shaped protective cover 4. At the same time, the processed parts are disassembled and replaced. As a further embodiment of the present invention, mounting grooves 201 are symmetrically provided on both sides of the mounting plate 2. One end of the mounting groove 201 is connected to a movable slide 202. Connecting rods 204 are slidably installed through the mounting groove 201 and the movable slide 202. One end of the two connecting rods 204 located inside the movable slide 202 passes through the movable slide 202 and is fixedly installed with a connecting plate 205. A limiting plate 203 is fixedly installed on the side of the connecting rod 204 located inside the mounting groove 201 away from the movable slide 202. A clamping spring 206 is provided on the surface of the connecting rod 204 located inside the mounting groove 201. The end of the two connecting rods 204 located away from the connecting plate 205 extends through the mounting groove 201 to the outside of the mounting plate 2 and is fixedly installed with a trapezoidal locking block 207. The protective mechanism 3 includes a protective frame 301. An end plate 302 is fixedly installed on one side inside the protective frame 301. Fixed slots 303 are symmetrically provided at the center of the surface of the end plate 302, and the fixed slots 303 correspond to the positions of the trapezoidal locking blocks 207. During operation, pushing the connecting plate 205 causes the connecting rod 204 to slide inside the mounting groove 201, causing the limiting plate 203 to deform the connecting plate 205 within the mounting groove 201. Simultaneously, the connecting rod 204 causes the trapezoidal locking block 207 to move closer to the mounting plate 2, thereby releasing the protective mechanism 3 and facilitating its removal from the surface of the machine tool 1. When the protective mechanism 3 is fixed in the machining position on the machine tool 1, pushing the protective mechanism 3 to cover the surface of the machine tool 1 causes the end plate 302 to move closer to the trapezoidal locking block 207, which in turn moves closer to the mounting plate 2, causing the trapezoidal locking block 207 to move closer to the mounting plate 2. 7. The connecting rod 204 and the limiting plate 203 slide inside the mounting groove 201, compressing the clamping spring 206 until the end plate 302 is pressed against the machine tool 1, so that the trapezoidal block 207 corresponds to the fixed slot 303. Under the rebound action of the clamping spring 206, the limiting plate 203 is lifted and reset inside the mounting groove 201, pushing the connecting rod 204 to drive the trapezoidal block 207 into the corresponding fixed slot 303, thereby pressing and fixing the end plate 302 against one side of the machine tool 1, which facilitates the connection and fixation of the protective mechanism 3 and the machine tool 1.

[0021] As a further embodiment of the present invention, universal wheels 304 are fixedly installed at the four corners of the bottom of the protective frame 301, and two T-shaped limiting strips 305 are fixedly installed on both sides of the inner wall of the protective frame 301. The T-shaped limiting strips 305 and the T-shaped limiting grooves 101 are positioned and have the same shape. Multiple movable rollers 306 are fixedly installed at equal intervals between the two T-shaped limiting strips 305 on the inner wall of the protective frame 301. The movable rollers 306 and the strip grooves 102 are positioned and correspond to each other. The top of the protective frame 301 is provided with a storage groove 307. The storage groove 307 has the same shape as the arc-shaped protective cover 4. The arc-shaped protective cover 4 is slidably connected to the inside of the storage groove 307. The top of both sides of the inner side of the protective frame 301 is symmetrically provided with arc-shaped sliding grooves 308. The arc-shaped sliding grooves 308 are connected to the storage grooves 307. The movable rollers 402 are slidably connected to the inside of the arc-shaped sliding grooves 308. During operation, when the protective frame 301 is placed over the machining position of the machine tool 1, the T-shaped limiting insert 305 and the first moving roller 306 on the inner wall of the protective frame 301 are engaged with the corresponding T-shaped limiting grooves 101 and strip grooves 102 on both sides of the machine tool 1. This ensures that the protective frame 301 will not shift position when it is fixed over the machining position of the machine tool 1. At the same time, the first moving roller 306 rolls inside the corresponding strip groove 102, reducing the friction between the inner wall of the protective frame 301 and the machine tool 1. When the arc-shaped protective cover 4 rotates at the top of the protective frame 301, it drives the second moving roller 402 to roll inside the corresponding arc-shaped sliding groove 308, thereby reducing the friction of the arc-shaped protective cover 4 when it rotates at the top of the protective frame 301. When the arc-shaped protective cover 4 rotates inside the top of the protective frame 301, the arc-shaped protective cover 4 is stored in the storage groove 307, which is the same shape as the arc-shaped protective cover 4.

[0022] As a further embodiment of the present invention, the springback reset mechanism 6 includes a first mounting block 601, which is fixedly connected to the arc-shaped protective cover 4. An arc-shaped mounting rod 602 is fixedly mounted on one side of the first mounting block 601, and an end block 603 is fixedly mounted on the end of the arc-shaped mounting rod 602 away from the first mounting block 601. A second mounting block 604 is slidably mounted through the surface of the arc-shaped mounting rod 602, and the second mounting block 604 is fixedly connected to the inner wall of the protective frame 301. An arc-shaped reset spring 605 is provided on the surface of the arc-shaped mounting rod 602 between the first mounting block 601 and the second mounting block 604. During operation, when the arc-shaped protective cover 4 rotates and retracts into the storage slot 307 at the top of the protective frame 301, it drives the mounting block 601 to rotate synchronously. This causes the mounting block 601 to push the arc-shaped mounting rod 602 to slide inside the mounting block 604, controlling the mounting block 601 and mounting block 604 to gradually approach each other. This compresses the arc-shaped return spring 605, causing it to deform on the surface of the arc-shaped mounting rod 602. When the arc-shaped protective cover 4 is pulled out from inside the storage slot 307, the arc-shaped return spring 605 rebounds and lifts the mounting block 601, applying elastic force to the return of the arc-shaped protective cover 4. This assists the arc-shaped protective cover 4 in rotating and closing at the top of the protective frame 301. At the same time, the end block 603 limits the arc-shaped mounting rod 602, preventing it from sliding off and falling inside the mounting block 604.

[0023] As a further embodiment of the present invention, the top two ends of the protective frame 301 are respectively fixedly installed with fixing buckles 309, the bottom of both ends of the mounting frame 7 are respectively symmetrically provided with limiting grooves 701, and the two ends of the mounting frame 7 are respectively symmetrically provided with connecting grooves 702, and the positions of the connecting grooves 702 and the fixing buckles 309 are corresponding. During operation, lift the mounting bracket 7 and press it against the top of the protective frame 301 so that the connecting slots 702 on both sides of the mounting bracket 7 correspond to the positions of the fixing buckles 309. Insert the fixing buckles 309 into the connecting slots 702 until the bottom of the fixing buckles 309 passes through the connecting slots 702, thereby clamping and fixing the mounting bracket 7 to the top of the protective frame 301.

[0024] As a further embodiment of the present invention, fixing blocks 703 are fixedly installed on both sides inside the mounting frame 7, and electric push rod 704 is fixedly installed on one side of the fixing block 703. A movable seat 705 is fixedly installed at the end of the electric push rod 704 away from the fixing block 703. Limiting protrusions 706 are fixedly installed on both sides of the movable seat 705, and the limiting protrusions 706 are slidably connected to the inside of the limiting groove 701. A rotating top frame 707 is rotatably installed on the top of the movable seat 705 through a pin. A connecting frame 708 is rotatably installed on the end of the rotating top frame 707 away from the movable seat 705 through a pin. A cleaning brush 709 is fixedly installed on the top of the two connecting frames 708, and the cleaning brush 709 is slidably connected to the top inside the mounting frame 7. During operation, when the arc-shaped protective cover 4 rotates at the top inside the protective frame 301, the control electric push rod 704 retracts, driving the movable seat 705 closer to the fixed block 703, so that the limiting protrusion 706 slides inside the corresponding limiting groove 701, ensuring that the movable seat 705 will not tilt or deflect during movement. When the movable seat 705 is close to the fixed block 703, the rotating top frame 707 rotates between the movable seat 705 and the connecting frame 708, lifting the cleaning brush 709 so that the top of the cleaning brush 709 is pressed against the inner wall of the arc-shaped protective cover 4. When the top of the cleaning brush 709 rotates, the cleaning brush 709 cleans the inner wall of the arc-shaped protective cover 4, removing the waste chips and coolant that the processing splashes from the machine tool 1 adhere to the inner wall of the arc-shaped protective cover 4, thus preventing the waste chips and coolant that the processing splashes from the machine tool 1 from sticking to the inner wall of the arc-shaped protective cover 4 for a long time and obstructing the view, which would affect the operator's observation of the processing status of the machine tool 1.

[0025] A method of using a tilting protective device for CNC machine tools, the method comprising the following steps: Push the protective frame 301 to one side of the machine tool 1, so that the T-shaped limiting inserts 305 and the moving rollers 306 on the inner wall of the protective frame 301 correspond to the T-shaped limiting grooves 101 and the strip grooves 102 on both sides of the machine tool 1. Push the protective frame 301 to cover the surface of the machine tool 1, so that the T-shaped limiting inserts 305 and the moving rollers 306 are inserted into the corresponding T-shaped limiting grooves 101 and strip grooves 102 until the end plate 302 contacts the trapezoidal locking block 207. Continue to push the end plate 302 to press it tightly against the machine tool 1, so that the end plate 302 squeezes the trapezoidal locking block 207. The trapezoidal locking block 207 is lifted close to the mounting plate 2, causing the trapezoidal locking block 207 to push the connecting rod 204 to drive the limiting plate 203 to slide inside the mounting groove 201, compressing the clamping spring 206 to deform until the end plate 302 is pressed against the processing machine tool 1, so that the fixed groove 303 corresponds to the position of the trapezoidal locking block 207. Under the rebound action of the clamping spring 206, the limiting plate 203 is lifted, driving the connecting rod 204 to lift the trapezoidal locking block 207 away from the mounting plate 2, so that the trapezoidal locking block 207 is inserted into the corresponding fixed groove 303, thereby clamping and fixing the protective frame 301 to the surface of the processing machine tool 1. Control the extension of the two electric push rods 5, so that the top of the electric push rod 5 lifts the rotating seat 501, which drives the arc-shaped protective cover 4 to rotate and retract into the storage groove 307. The arc-shaped protective cover 4 drives the mounting block 601 to approach the mounting block 604, squeezing the arc-shaped return spring 605 to deform on the surface of the arc-shaped mounting rod 602 until the arc-shaped protective cover 4 is retracted into the storage groove 307. Then lift the mounting frame 7, align the connecting slots 702 on both sides of the mounting frame 7 with the fixing buckles 309, and insert the fixing buckles 309 into the corresponding connecting slots 702 to clamp and fix the mounting frame 7 between the two fixing buckles 309. Before the machining machine 1 starts machining, the electric push rod 5 is controlled to retract and rotate between the rotating seat 501 and the rotating seat 502, pulling the rectangular baffle 401 to rotate on one side of the protective frame 301, pulling the arc-shaped protective cover 4 out from the storage slot 307. At the same time, the arc-shaped return spring 605 rebounds between the mounting block 601 and the mounting block 604, so that the arc-shaped protective cover 4 returns to its original position and covers the machining position of the machining machine 1. After the rectangular baffle 401 rotates to close to the protective frame 301 and closes, the machining machine 1 is controlled to start machining. After the machining process is completed, the machining machine 1 is stopped, the fixed block 703 is retracted, the movable seat 705 is moved to both ends of the mounting frame 7, the rotating top frame 707 on the top of the movable seat 705 is rotated, so that the two rotating top frames 707 lift the cleaning brush 709 until the cleaning brush 709 is lifted and pressed against the surface of the arc-shaped protective cover 4. At the same time, the electric push rod 5 is extended to lift the rectangular baffle 401 and drive the arc-shaped protective cover 4 into the storage groove 307, so that the arc-shaped protective cover 4 slides at the bottom of the cleaning brush 709 to clean the waste chips and coolant that splashed and stuck to the inner wall of the arc-shaped protective cover 4 during the machining process of the machining machine 1.
