Description

Technical Field

[0001] The invention belongs to the field of pipe processing, in particular to a chip removal and cleaning device for a numerically controlled machine tool. Background Art

[0002] CNC machine tools generate a lot of debris during the processing process. If the debris stays in the machine tool for a long time, it will affect the CNC machine tool itself. Therefore, it is necessary to regularly remove the chips from the CNC machine tool to prevent the accumulation of debris and affect the processing efficiency and accuracy of the machine tool. At present, most of them are cleaned manually or by chip removal devices. The existing chip removal device requires manual handheld collection equipment to collect the debris, which has a small collection range and is time-consuming and labor-intensive.

[0003] The chip removal cleaning device for CNC machine tools is an auxiliary device used to process the chip waste on the workbench after the use of the CNC machine tool so that the machine tool can work better. It has been widely used in the field of CNC machine tools. However, the existing machine tool chip removal cleaning device still finds it difficult to clean the debris in the gap of the machine tool. Manual cleaning is still required, and the cleaning efficiency is low and the effect is poor. The edges and corners of the machine tool are relatively sharp, which may cause scratches to personnel during cleaning. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a chip removal and cleaning device for a numerically controlled machine tool, which solves the problem that the chips in the gaps of the machine tool are difficult to clean.

Since the device adopts an extraction collection method, and the debris is usually relatively small and light in weight, the device can easily suck the debris into the movable push box to complete the debris cleaning work, and during the cleaning process, the exhaust hood can protect the user's hands from the risk of scratches and stabs, the product is safer, and when the device is finished working, the user lets go, and the elastic telescopic tube can be retracted into the extension slide tube under the action of its own deformation force, so that the tidying work is more convenient.

[0006] Preferably, the mobile push box includes a box shell, an isolation protective shell is fixedly connected to the center of the bottom of the inner wall of the box shell, the bottom of the inner wall of the isolation protective shell is fixedly connected to an air pump via a support block, vertical conduits are symmetrically arranged on both sides of the outer surface of the air pump, the bottom ends of the vertical conduits extend to the inner cavity of the air pump, the top ends of the vertical conduits are fixedly connected to a protective sleeve, the top ends of the protective sleeve extend to the upper surface of the mobile push box, and a reverse blockage is arranged at the bottom of the inner wall of the protective sleeve. Since the vertical conduits of the device are located on both sides of the inner cavity of the protective sleeve, debris entering the protective sleeve will gather at the bottom of the inner wall of the protective sleeve under the influence of its own gravity. Under the protection of the relevant filtering device, the possibility of debris entering the vertical conduits is extremely small, so the probability of the air pump being interfered with and stuck by debris is also extremely small, and the service life of the device is also longer.

[0007] Preferably, the mobile push box includes a modified drawer shell, the number of the modified drawer shells is two, both sides of the outer surface of the modified drawer shell are slidably connected to the inner wall of the box shell, the middle part of the outer surface of the modified drawer shell is slidably connected with a guide device, the upper surface of the guide device is fixedly connected to the lower surface of the protective sleeve, and the lower surface of the guide device is fixedly connected to the upper surface of the isolation protective shell.

[0008] Preferably, the reverse blockage includes a tension shaft rod, the lower part of the outer surface of the tension shaft rod is fixedly connected with a hinged connecting rod, the top of the hinged connecting rod is fixedly connected with a side clamping ring, the lower part of the outer surface of the tension shaft rod is rotatably connected to the inner wall of the side clamping ring through the hinged connecting rod, the outer surface of the side clamping ring is fixedly connected to the inner wall of the protective sleeve, the bottom end of the tension shaft rod is fixedly connected with a semicircular block, the bottom end of the semicircular block extends to the interior of the guide device through the ring mouth, when the device is collecting, it will gather inside the protective sleeve and will not enter other places, preventing debris from flying inside the device under the influence of airflow, when the vacuum pump stops working, the semicircular block slides down under its own gravity, the gap above the bar frame is opened, and the debris enters the bar frame from the gap. At this time, the debris is only affected by its own gravity, and the movement is relatively stable.

[0009] Preferably, the guiding device comprises a bar frame, the lower surface of the bar frame is fixedly connected to the upper surface of the isolation protective shell, the middle part of the inner wall of the bar frame is rotatably connected to a cam, both ends of the cam are rotatably connected to the inner cavity of the bar frame, both sides of the outer surface of the cam are slidably connected to rubber strips, the rear end of the rubber strip is fixedly connected to the outer surface of the modified drawer shell, and the middle part of the outer surface of the cam is slidably connected to a partition bevel.

[0010] Preferably, a ring opening is provided at the top of the inner cavity of the strip frame, the bottom end of the semicircular clamping block extends to the inside of the strip frame through the ring opening, and the upper surface of the semicircular clamping block is clamped with the top of the inner wall of the strip frame.

[0011] Preferably, the modified extraction shell includes a debris holding frame, both sides of the outer surface of the debris holding frame are slidably connected to the inner wall of the box shell, the lower surface of the debris holding frame is slidably connected to the bottom of the inner wall of the box shell, the front of the debris holding frame is symmetrically provided with an external sliding rod, the outer surface of the external sliding rod is rotatably connected to a clamping plate, the inner wall of the clamping plate is fixedly connected to a spring arc plate, and the two ends of the inner cavity of the clamping plate are slidably connected to an elastic drawstring, and the center of the front of the debris holding frame is fixedly connected to the rear end of the rubber strip. Since the debris holding frame is slidably connected to the box shell in a pulling manner, each time the debris holding frame is pulled out of the box shell or inserted into the box shell, the rubber strip can slide in the horizontal plane, and then drive the cam to rotate by friction. When the cam rotates, it will continuously hit the lower surface of the partition oblique block, so that the debris remaining above the partition oblique block slides into the interior of the debris holding frame under the influence of vibration, thereby reducing the residue of internal debris.

[0012] Preferably, the dividing bevel block comprises a triangular bevel block, the bottom end of the inner wall of the triangular bevel block is slidably connected with a push plate, the lower surface of the push plate is slidably connected to the middle part of the outer surface of the cam, the middle part of the upper surface of the push plate is fixedly connected with a buffer spring plate, the top end of the buffer spring plate is fixedly connected to the top of the inner wall of the triangular bevel block, the upper surface of the push plate is symmetrically provided with oblique push arms, the upper surface of the triangular bevel block is symmetrically provided with a vibration belt, the top end of the oblique push arm extends to the outside of the triangular bevel block through a groove, and the top end of the oblique push arm is fixedly connected to the lower surface of the vibration belt.

[0013] The beneficial effects of the present invention are as follows: 1. When cleaning the debris on the machine tool, the user draws out the elastic telescopic tube from the extension slide tube through the vacuum hood, and the extension slide tube is stretched. With the user's manipulation, the mobile push box sucks the debris on the machine tool from the elastic telescopic tube into the interior of the mobile push box to complete the debris cleaning process. Since the device adopts an extraction collection method, and the debris is usually small and light, the device can easily suck the debris into the mobile push box to complete the debris cleaning work. In the cleaning process, the vacuum hood can protect the user's hands from the risk of scratches and punctures, and the product is safer. When the device is finished working, the user lets go, and the elastic telescopic tube can shrink into the extension slide tube under the action of its own deformation force, making the tidying work more convenient.

[0014] 2. When the device is working, the vacuum pump works and vacuums the upper part of the protective sleeve through the vertical ducts on both sides. The pressure inside the protective sleeve is reduced, and both ends of the protective sleeve generate a large attraction force. The debris is transported to the inside of the protective sleeve through the elastic telescopic tube. Under the action of pressure, it gathers inside the protective sleeve, thereby completing the collection process of external debris. Since the vertical ducts of the device are located on both sides of the inner cavity of the protective sleeve, the debris entering the protective sleeve will gather at the bottom of the inner wall of the protective sleeve under the influence of its own gravity. Under the protection of the relevant filtering device, the possibility of debris entering the vertical duct is extremely small, so the probability of the vacuum pump being interfered by debris and stuck is also extremely small, and the service life of the device is also longer.

[0015] 3. When the vacuum pump is pumping air, the reverse blocking under the action of pressure, the semicircular block slides up, blocking the hole above the strip frame, so that the debris entering the protective sleeve will be gathered inside the protective sleeve when the device is collecting, and will not enter other places, preventing the debris from flying inside the device under the influence of airflow. When the vacuum pump stops working, the semicircular block slides down under its own gravity, the gap above the strip frame is opened, and the debris enters the strip frame from the gap. At this time, the debris is only affected by its own gravity, and the movement is relatively stable.

[0016] 4. Since the debris holding frame is slidably connected to the box shell by a pull-out method, each time the debris holding frame is pulled out of the box shell or inserted into the box shell, the rubber strip can slide in the horizontal plane, and then drive the cam to rotate through friction. When the cam rotates, it will continuously hit the lower surface of the dividing bevel block, so that the debris remaining above the dividing bevel block will slide into the interior of the debris holding frame under the influence of vibration, thereby reducing the residue of internal debris.

[0017] 5. When the debris holding frame is full, it is necessary to take out the debris holding frame and dump it. Under normal circumstances, the user will often pull out the debris holding frame to check whether there is any abnormality in the debris situation and check the storage capacity of the debris. The debris holding frame has no restrictions and can easily slide out of the box shell. When the debris holding frame holds a small amount of debris, the user may use too much force, causing the debris holding frame to collide with the box shell, thereby producing adverse effects. At this time, the splint will rotate to varying degrees with the movement of the debris holding frame. The spring arc plate limits the rotation of the splint through elastic force, thereby preventing the movement of the debris holding frame. When moving the debris holding frame, the user will gradually feel the resistance from the debris holding frame, prompting the user to reduce the force, while also buffering the impact force between the debris holding frame and the box shell.

[0018] 6. If the cam directly hits the bottom surface of the dividing bevel block, the dividing bevel block will vibrate. In the long run, the dividing bevel block is prone to dislocation and lose its guiding ability. Therefore, the dividing bevel block needs to be optimized. When the cam hits the dividing bevel block, the push plate rises due to the impact force, pushing the inclined push arms on both sides to rise. The top of the inclined push arm pushes the lower surface of the vibration belt upward, and the curvature of the vibration belt is deformed. When the cam separates from the push plate, the push plate quickly slides down and resets under the action of its own gravity and the elastic force of the buffer spring plate, and the vibration belt recovers. Therefore, when the debris holding frame slides, the vibration belt vibrates continuously, shaking off the debris on the upper surface of the vibration belt into the debris holding frame, greatly reducing the vibration force on the dividing bevel block and preventing the dividing bevel block from being dislocated and losing its ability to guide the debris.

An extension slide tube 2 is fixedly connected to the upper surface of the mobile push box 1, and the bottom end of the extension slide tube 2 extends to the interior of the mobile push box 1. An elastic telescopic tube 3 is slidably connected to the inner wall of the extension slide tube 2. The bottom end of the elastic telescopic tube 3 extends to the interior of the mobile push box 1, and the top end of the elastic telescopic tube 3 extends to the outside of the extension slide tube 2. The top end of the elastic telescopic tube 3 is fixedly connected to an exhaust hood. When cleaning the debris on the machine tool, the user draws the elastic telescopic tube 3 out of the extended slide tube 2 through the vacuum hood, and the extended slide tube 2 is stretched. With the user's manipulation, the mobile push box 1 sucks the debris on the machine tool from the elastic telescopic tube 3 into the interior of the mobile push box 1 to complete the debris cleaning process. Since the device adopts an extraction collection method, and the debris is usually small and light in weight, the device can easily suck the debris into the mobile push box 1 to complete the debris cleaning work. In addition, during the cleaning process, the vacuum hood can protect the user's hands from the risk of scratches and punctures, and the product is safer.

[0023] The mobile push box 1 includes a box shell 11, and an isolation protection shell 14 is fixedly connected to the center of the bottom of the inner wall of the box shell 11.

The top end of the vertical conduit 15 is fixedly connected to a protective sleeve 12. The top end of the protective sleeve 12 extends to the upper surface of the mobile push box 1, and a reverse plug 5 is arranged at the bottom of the inner wall of the protective sleeve 12.

[0024] The mobile push box 1 includes a modified drawer shell 7, the number of the modified drawer shells 7 is two, both sides of the outer surface of the modified drawer shell 7 are slidably connected to the inner wall of the box shell 11, the middle part of the outer surface of the modified drawer shell 7 is slidably connected with a guide device 6, the upper surface of the guide device 6 is fixedly connected to the lower surface of the protective sleeve 12, and the lower surface of the guide device 6 is fixedly connected to the upper surface of the isolation protective shell 14. When the device is working, the air pump 13 works to evacuate the upper part of the protective sleeve 12 through the vertical conduits 15 on both sides, the pressure inside the protective sleeve 12 is reduced, and the protective sleeve Both ends of the tube 12 generate a large attraction force, and the debris is transported to the interior of the protective sleeve tube 12 through the elastic telescopic tube 3. Under the action of pressure, it gathers inside the protective sleeve 12, thereby completing the collection process of external debris. Since the vertical conduit 15 of the device is located on both sides of the inner cavity of the protective sleeve 12, the debris entering the protective sleeve will gather at the bottom of the inner wall of the protective sleeve under the influence of its own gravity. Under the protection of the relevant filtering device, the possibility of debris entering the vertical conduit 15 is extremely small, so the probability of the vacuum pump 13 being interfered by debris and stuck is also extremely small, and the service life of the device is also longer.

[0025] The reverse plug 5 includes a tension shaft 51, the lower part of the outer surface of the tension shaft 51 is fixedly connected with a hinged connecting rod 53, the top of the hinged connecting rod 53 is fixedly connected with a side clamping ring 52, the lower part of the outer surface of the tension shaft 51 is rotatably connected to the inner wall of the side clamping ring 52 through the hinged connecting rod 53, the outer surface of the side clamping ring 52 is fixedly connected to the inner wall of the protective sleeve 12, and the bottom end of the tension shaft 51 is fixedly connected with a semicircular clamping block 54, the bottom end of the semicircular clamping block 54 extends to the inside of the guide device 6 through the ring mouth, and is pumped by the vacuum pump 13. When the air is exhausted, the reverse plug 5 slides up under the action of pressure, and the semicircular block 54 blocks the hole above the strip frame 61. In this way, the debris entering the protective sleeve 12 will be gathered inside the protective sleeve 12 when the device is collecting, and will not enter other places, preventing the debris from flying inside the device under the influence of airflow. When the vacuum pump 13 stops working, the semicircular block 54 slides down under the action of its own gravity, and the gap above the strip frame 61 is opened, and the debris enters the strip frame 61 from the gap. At this time, the debris is only affected by its own gravity, and the movement is relatively stable.

[0026] The guiding device 6 includes a bar frame 61, the lower surface of the bar frame 61 is fixedly connected to the upper surface of the isolation protection shell 14, the middle part of the inner wall of the bar frame 61 is rotatably connected to a cam 63, both ends of the cam 63 are rotatably connected to the inner cavity of the bar frame 61, both sides of the outer surface of the cam 63 are slidably connected to rubber strips 62, the rear end of the rubber strip 62 is fixedly connected to the outer surface of the modified drawer shell 7, and the middle part of the outer surface of the cam 63 is slidably connected to a partition bevel 8.

[0027] A ring opening is provided at the top of the inner cavity of the strip frame 61, and the bottom end of the semicircular block 54 extends to the inside of the strip frame 61 through the ring opening. The upper surface of the semicircular block 54 is clamped with the top of the inner wall of the strip frame 61. Since the debris holding frame 71 is slidably connected to the box shell 11 in a pulling manner, each time the debris holding frame 71 is pulled out of the box shell 11 or inserted into the box shell 11, the rubber strip 62 can slide in the horizontal plane, and then drive the cam 63 to rotate through friction. When the cam 63 rotates, it will continuously hit the lower surface of the dividing bevel block 8, so that the debris remaining above the dividing bevel block 8 will slide into the inside of the debris holding frame 71 under the influence of vibration, thereby reducing the residual debris inside.

[0028] The modified extraction shell 7 includes a debris holding frame 71, both sides of the outer surface of the debris holding frame 71 are slidably connected to the inner wall of the box shell 11, the lower surface of the debris holding frame 71 is slidably connected to the bottom of the inner wall of the box shell 11, the front of the debris holding frame 71 is symmetrically provided with external sliding rods 73, the outer surface of the external sliding rod 73 is rotatably connected to a clamping plate 72, the inner wall of the clamping plate 72 is fixedly connected to a spring arc plate 74, and both ends of the inner cavity of the clamping plate 72 are slidably connected to elastic drawstrings 75, the center of the front of the debris holding frame 71 is fixedly connected to the rear end of the rubber strip 62, and the debris is guided by the dividing oblique block 8 and enters the debris holding frames 71 on both sides. When the debris holding frame 71 is full, the debris holding frame 71 needs to be taken out and dumped. Under normal circumstances, the user will often pull out the debris holding frame 71 to check whether there is any abnormality in the debris situation and check the storage capacity of the debris. The debris holding frame 71 has no restrictions and can easily slide out of the box shell 11. When the debris holding frame 71 holds a small amount of debris, the user may use too much force, causing the debris holding frame 71 to collide with the box shell 11, thereby producing adverse effects. At this time, the splint 72 will rotate to varying degrees with the movement of the debris holding frame 71, and the spring arc plate 74 limits the rotation of the splint 72 through elastic force, thereby preventing the movement of the debris holding frame 71. When moving the debris holding frame 71, the user will gradually feel the resistance from the debris holding frame 71, prompting the user to reduce the force, while also buffering the impact force between the debris holding frame 71 and the box shell 11.

[0029] The partition bevel 8 includes a triangular bevel 81, the bottom end of the inner wall of the triangular bevel 81 is slidably connected with a push plate 84, the lower surface of the push plate 84 is slidably connected to the middle part of the outer surface of the cam 63, the middle part of the upper surface of the push plate 84 is fixedly connected with a buffer spring plate 85, the top end of the buffer spring plate 85 is fixedly connected to the top of the inner wall of the triangular bevel 81, the upper surface of the push plate 84 is symmetrically provided with oblique push arms 83, the upper surface of the triangular bevel 81 is symmetrically provided with vibration belts 82, the top end of the oblique push arms 83 extends to the outside of the triangular bevel 81 through a slot, the top end of the oblique push arms 83 is fixedly connected to the lower surface of the vibration belt 82, if the cam 63 directly hits the bottom surface of the partition bevel 8, the partition bevel 8 will vibrate, and the long-term downward movement The partition bevel 8 is prone to dislocation and lose its guiding ability, so the partition bevel 8 needs to be optimized. When the cam 63 hits the partition bevel 8, the push plate 84 is impacted and rises, pushing the oblique push arms 83 on both sides to rise. The top of the oblique push arms 83 pushes the lower surface of the vibration belt 82 upward, and the curvature of the vibration belt 82 is deformed. When the cam 63 separates from the push plate 84, the push plate 84 quickly slides down and resets under the action of its own gravity and the elastic force of the buffer spring plate 85, and the vibration belt 82 recovers. Therefore, when the debris holding frame 71 slides, the vibration belt 82 vibrates continuously, shaking off the debris on the upper surface of the vibration belt 82 into the debris holding frame 71, greatly reducing the vibration force on the partition bevel 8 and preventing the partition bevel 8 from being dislocated and losing the ability to guide the debris.

[0030] The specific workflow is as follows: When the device is working, the vacuum fan 13 works to evacuate the upper part of the protective sleeve 12 through the vertical ducts 15 on both sides, the pressure inside the protective sleeve 12 is reduced, and both ends of the protective sleeve 12 generate a large attraction force, and the debris is transported to the inside of the protective sleeve 12 through the elastic telescopic tube 3, and under the action of pressure, it gathers inside the protective sleeve 12, thereby completing the collection process of external debris. Since the vertical ducts 15 of the device are located on both sides of the inner cavity of the protective sleeve 12, the debris entering the protective sleeve will gather at the bottom of the inner wall of the protective sleeve under the influence of its own gravity. Under the protection of the relevant filtering device, the possibility of debris entering the vertical duct 15 is extremely small, so the probability of the vacuum fan 13 being interfered by debris and stuck is also extremely small, and the service life of the device is also longer.

[0031] When the vacuum pump 13 is pumping air, the reverse plug 5 slides up under the action of pressure, and the semicircular block 54 blocks the hole above the strip frame 61. In this way, the debris entering the protective sleeve 12 will be gathered inside the protective sleeve 12 when the device is collecting, and will not enter other places, preventing the debris from flying inside the device under the influence of airflow. When the vacuum pump 13 stops working, the semicircular block 54 slides down under the action of its own gravity, and the gap above the strip frame 61 is opened, and the debris enters the strip frame 61 from the gap. At this time, the debris is only affected by its own gravity, and the movement is relatively stable.

[0032] Since the debris holding frame 71 is slidably connected to the box shell 11 by a pulling method, each time the debris holding frame 71 is pulled out of the box shell 11 or inserted into the box shell 11, the rubber strip 62 can slide in the horizontal plane, and then drive the cam 63 to rotate through friction. When the cam 63 rotates, it will continuously hit the lower surface of the dividing bevel 8, so that the debris remaining above the dividing bevel 8 will slide into the interior of the debris holding frame 71 under the influence of vibration, thereby reducing the residue of internal debris.

[0033] When the debris holding frame 71 is full, it is necessary to take out the debris holding frame 71 and dump it. Under normal circumstances, the user will often pull out the debris holding frame 71 to check whether there is any abnormality in the debris situation and check the storage amount of the debris. The debris holding frame 71 has no restrictions and can easily slide out of the box shell 11. When the debris holding frame 71 contains a small amount of debris, the user may use too much force, causing the debris holding frame 71 to collide with the box shell 11, thereby producing adverse effects. At this time, the splint 72 will rotate to varying degrees with the movement of the debris holding frame 71. The spring arc plate 74 limits the rotation of the splint 72 through elastic force, thereby preventing the movement of the debris holding frame 71. When moving the debris holding frame 71, the user will gradually feel the resistance from the debris holding frame 71, prompting the user to reduce the force, while also buffering the impact force between the debris holding frame 71 and the box shell 11.

[0034] If the cam 63 directly hits the bottom surface of the dividing bevel 8, the dividing bevel 8 will vibrate. In the long run, the dividing bevel 8 is prone to dislocation and lose its guiding ability. Therefore, it is necessary to optimize the dividing bevel 8. When the cam 63 hits the dividing bevel 8, the push plate 84 is subjected to the impact force and rises, pushing the oblique push arms 83 on both sides to rise. The top of the oblique push arms 83 pushes the lower surface of the vibration belt 82 upward, and the curvature of the vibration belt 82 is deformed. When the cam 63 separates from the push plate 84, the push plate 84 quickly slides down and resets under the action of its own gravity and the elastic force of the buffer spring plate 85, and the vibration belt 82 recovers. Therefore, when the debris holding frame 71 slides, the vibration belt 82 continues to vibrate, shaking off the debris on the upper surface of the vibration belt 82 into the debris holding frame 71, greatly reducing the vibration force on the dividing bevel 8 and preventing the dividing bevel 8 from being dislocated and losing the ability to guide the debris.
