Description

Technical Field

[0001] This invention relates to CNC machine tools, and more specifically, to a chip removal and cleaning device for CNC machine tools. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] Patent document CN217728034U discloses a chip removal and cleaning device for CNC machine tools, comprising: a base, a main body fixedly installed on the top of the base, an inclined groove opened on the top of the main body, a filter screen fixedly installed inside the main body and on one side of the inclined groove, and an inclined block fixedly installed inside the main body and on one side of the filter screen.

[0004] The aforementioned application describes how, due to the slope of the chute, both cutting fluid and iron filings move downwards onto the filter screen. The filter screen blocks the iron filings, while the cutting fluid falls through the filter screen into the first collection box below. The collected cutting fluid can be reused. When the scraper contacts the chute, the continued rotation of the shaft causes the telescopic rod to move inwards into the telescopic sleeve. At this time, the second spring is compressed, and the scraper contacts the filter screen, effectively scraping the iron filings on the filter screen surface into the second collection box for collection and centralized processing. However, the scraper's movement trajectory is lateral, which may cause some waste to move towards the chute. Furthermore, the scraper's position above the filter screen for a long time may also affect the movement of waste. Therefore, improvements are needed. Summary of the Invention

[0005] This invention proposes a chip removal and cleaning device for CNC machine tools.

[0006] The technical solution of the present invention is as follows: A chip removal and cleaning device for CNC machine tools includes a base plate, a body, a first waste liquid tank, and a second waste liquid tank fixedly connected to the top of the base plate. A first feeding plate, a support plate, and a second feeding plate are fixedly connected to the inner side of the body. A chip removal mechanism and an intermittent blocking mechanism are provided on the inner side of the body. A shaking mechanism is provided inside the second waste liquid tank. The chip removal mechanism includes a drive shaft, a driven shaft, a transmission belt, a first motor, and a filter screen. The drive shaft and the driven shaft are rotatably connected to the inner side of the body. The driven shaft is driven by the drive shaft through the transmission belt. A connecting block is fixedly connected to the bottom of the transmission belt, and a brush is fixedly connected to the bottom of the connecting block. The first motor is fixedly installed at the front end of the body, and the filter screen is fixedly connected to the top of the support plate. The intermittent blocking mechanism includes a fixed... The device consists of a groove and an arc-shaped block B. The groove is fixedly connected to the inside of the machine body. A compression spring is installed inside the groove, and a blocking plate is slidably connected to it via the spring. A pressure chamber is fixedly connected to the bottom of the groove. A pressure rod is slidably connected to a piston inside one end of the pressure chamber. An arc-shaped block A is fixedly connected to the end of the pressure rod away from the pressure chamber. A push rod is slidably connected to a piston inside the other end of the pressure chamber. The arc-shaped block B is fixedly connected to the surface of the driven shaft. By setting an intermittent blocking mechanism, when the first motor is turned on to drive the drive shaft to rotate and cooperate with the driven shaft and the transmission belt to move the brush, the blocking plate will also be driven to rise intermittently through the cooperation of the arc-shaped block B, arc-shaped block A, and pressure chamber to block the cutting fluid and prevent too much cutting fluid from flowing down in a short time and affecting the filtration of the filter screen.

[0007] The entire device is installed next to the CNC machine tool. Cutting fluid mixed with waste chips is discharged to the top of the first discharge plate, flowing along it to the support plate. The cutting fluid falls through the filter screen into the first waste liquid tank for collection, facilitating subsequent recycling. The waste chips remain on the filter screen. At this point, the first motor can be turned on. The first motor drives the drive shaft to rotate via the output shaft. The drive shaft's rotation drives the driven shaft to rotate via the transmission belt. The connecting block moves with the transmission belt, and the movement of the connecting block drives the brush to move. The brush's movement moves the waste chips on the filter screen towards the second discharge plate. This chip removal effect is good and does not easily affect the movement of the waste chips. Subsequently, the waste chips on the second discharge plate slide onto the screen. The rotation of the drive shaft also drives the rotating gear to rotate. Initially, the rotating gear rotates, causing the rack to move upward. The upward movement of the rack drives the push rod to move upward. The upward movement of the push rod, through the hydraulic pressure in the hydraulic chamber, drives the connecting rod to move downward. The moving mechanism causes the screen to move downwards, compressing the return spring. When the rotating gear rotates to the toothless part and disengages from the rack, the return spring rebounds, causing the screen to bounce back to its original position. This cycle repeats, causing the waste chips on the screen to shake off, dislodging any residual cutting fluid onto the chips and collecting it in the second waste fluid tank. The driven shaft's rotation also causes the arc-shaped block B to rotate. During this rotation, the arc-shaped block B presses against the arc-shaped block A, causing the pressure rod to move into the air chamber. The pressure rod's movement into the air chamber, combined with the air pressure, causes the push rod to move upwards. This upward movement of the push rod causes the blocking plate to move upwards, stretching the compression spring. When the arc-shaped block B leaves the arc-shaped block A, the compression spring rebounds, causing the blocking plate and push rod to move downwards to their original positions. The air pressure then causes the pressure rod and arc-shaped block A to move in the opposite direction to their original positions. The intermittent rise of the blocking plate blocks the cutting fluid, preventing excessive cutting fluid from flowing down in a short time and affecting the filter screen's filtration.

[0008] By incorporating a chip removal mechanism, when the first motor is turned on and drives the drive shaft to rotate, the driven shaft, connecting block, and other components will work together to move the chip removal brush along with the transmission belt. The movement of the chip removal brush will cause the waste chips on the filter screen surface to move towards the second discharge plate, while the cutting fluid will be discharged into the first waste liquid tank for storage, facilitating recycling. The chip removal effect is good and does not easily affect the movement of waste chips.

[0009] A drain pipe is fixedly connected to the side of the first waste liquid tank. The output shaft of the first motor is fixedly connected to the drive shaft. The cutting fluid in the first waste liquid tank can be discharged through the drain pipe. Turning on the first motor can drive the drive shaft to rotate.

[0010] Both the first and second feeding plates are inclined. The bristles of the brush contact the top of the filter screen. The top of the base plate is provided with a pulling mechanism. The end of the push rod away from the air pressure chamber is fixedly connected to the bottom of the blocking plate. When the brush moves, it will drive the waste on the surface of the filter screen to move towards the second feeding plate.

[0011] The shaking mechanism includes a rotating gear, a sliding rod, and a hydraulic chamber. The rotating gear is fixedly connected to the surface of the drive shaft. The sliding rod is fixedly connected to the bottom of the second waste liquid tank. A screen is slidably connected to the surface of the sliding rod, and a return spring is sleeved on the surface of the sliding rod. The hydraulic chamber passes through and is fixedly connected to the top of the second feed plate. A push rod is slidably connected to a piston inside one end of the hydraulic chamber. A gear is fixedly connected to the end of the push rod away from the hydraulic chamber. A connecting rod is slidably connected to a piston inside the other end of the hydraulic chamber. By setting up the shaking mechanism, during the process of starting the first motor and driving the drive shaft to rotate, the screen moves downward and then bounces back up through the cooperation of the rotating gear, gear, hydraulic chamber, and other components. The shaking of the screen also shakes the waste chips on it, causing the residual cutting fluid on the waste chips to fall into the second waste liquid tank for collection.

[0012] The rotating gear is an incomplete gear, and the teeth on the rotating gear are initially engaged with the teeth on the rack. When the rotating gear rotates at the beginning, it drives the rack to move upward.

[0013] The end of the connecting rod away from the hydraulic chamber is fixedly connected to the bottom of the screen. The two ends of the return spring are respectively in contact with the bottom of the second waste liquid tank and the bottom of the screen. When the connecting rod moves downward, it will drive the screen to move downward, and the return spring will be compressed.

[0014] The extraction mechanism includes a second motor, a rotating rod, and a piston cylinder. The second motor is fixedly installed at the front end of the machine body. The rotating rod is rotatably connected to the inside of the machine body, and a cam is fixedly connected to the surface of the rotating rod. The piston cylinder is fixedly connected to the top of the base plate, and a telescopic spring is installed inside the piston cylinder. A piston rod is slidably connected inside the piston cylinder through the telescopic spring. A pressure plate is fixedly connected to the top of the piston rod. A suction tube and a delivery tube are respectively inserted and fixedly connected to both sides of the piston cylinder. Both the suction tube and the delivery tube are equipped with one-way valves. By setting up the extraction mechanism, when the second motor is turned on to drive the rotating rod to rotate, the cam, pressure plate, piston cylinder, piston rod, and other components work together to allow the suction tube to draw cutting fluid from the second waste liquid tank and deliver it to the first waste liquid tank for centralized collection through the delivery tube, thus improving the overall convenience of use.

[0015] The pressure plate is located directly below the cam. The end of the cam away from the rotating rod is provided with grease. When the cam rotates with the rotating rod, it will repeatedly squeeze the pressure plate to make it move downward. The grease can reduce wear.

[0016] The one-way valve inside the suction tube is designed to allow unidirectional flow towards the inside of the piston cylinder. The end of the suction tube away from the piston cylinder is connected to the second waste liquid tank through and fixedly connected. When a negative pressure is formed inside the piston cylinder, the cutting fluid in the second waste liquid tank will be drawn in through the suction tube.

[0017] The end of the infusion tube away from the piston cylinder is connected to the first waste liquid tank through and fixedly connected. The one-way valve inside the infusion tube is unidirectional towards the inside of the first waste liquid tank. When the cutting fluid in the piston cylinder is squeezed, it will be discharged into the first waste liquid tank through the infusion tube.

[0018] The working principle and beneficial effects of this invention are as follows: 1. This invention, by setting up a chip removal mechanism, achieves the following: when the first motor is turned on to drive the drive shaft to rotate, the driven shaft, connecting block and other components will drive the brush to move with the transmission belt. The movement of the brush will drive the waste chips on the surface of the filter screen to move towards the second feed plate, while the cutting fluid is discharged into the first waste liquid tank for storage, which is convenient for recycling. The chip removal effect is good and it does not easily affect the movement of waste chips.

[0019] 2. By incorporating an intermittent blocking mechanism, this invention achieves the following: when the first motor drives the active shaft to rotate and, in conjunction with the driven shaft and transmission belt, moves the brush, the blocking plate is also intermittently raised by components such as arc-shaped block B, arc-shaped block A, and air pressure chamber to block the cutting fluid, preventing excessive cutting fluid from flowing down in a short time and affecting the filtration of the filter screen.

[0020] 3. By incorporating a shaking mechanism, this invention achieves the following: during the process of starting the first motor and driving the drive shaft to rotate, the screen moves downward and then bounces back up through the cooperation of components such as rotating gears, racks, and hydraulic chambers. The shaking of the screen causes the waste chips on it to shake as well, shaking off the residual cutting fluid on the waste chips into the second waste liquid tank for collection.

[0021] 4. By incorporating an extraction mechanism, this invention enables the second motor to drive the rotating rod to rotate. Through the cooperation of components such as the cam, pressure plate, piston cylinder, and piston rod, the suction pipe draws the cutting fluid from the second waste liquid tank and transports it to the first waste liquid tank for centralized collection via the delivery pipe, thereby improving the overall convenience of use.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1 like Figures 1-9As shown, this embodiment proposes a chip removal and cleaning device for CNC machine tools, including a base plate 1. A body 2, a first waste liquid tank 5, and a second waste liquid tank 7 are fixedly connected to the top of the base plate 1.

Both the drive shaft 91 and the driven shaft 92 are rotatably connected to the inner side of the body 2. The driven shaft 92 is connected to the drive shaft 91 via the transmission belt 93. The side of the first waste liquid tank 5... A drain pipe 8 is connected through and fixedly connected. The output shaft of the first motor 96 is fixedly connected to the drive shaft 91. The cutting fluid in the first waste liquid tank 5 can be discharged through the drain pipe 8. Turning on the first motor 96 can drive the drive shaft 91 to rotate. A connecting block 94 is fixedly connected to the bottom of the transmission belt 93. A brush 95 is fixedly connected to the bottom of the connecting block 94. The first motor 96 is fixedly installed at the front end of the machine body 2. The filter screen 97 is fixedly connected to the top of the support plate 4. The first feeding plate 3 and the second feeding plate 6 are both inclined. The bristles of the brush 95 are in contact with the top of the filter screen 97. When the brush 95 moves, it will drive the waste on the surface of the filter screen 97 to move towards the second feeding plate 6.The intermittent blocking mechanism 12 includes a fixed groove 121 and an arc-shaped block B128. The fixed groove 121 is fixedly connected to the inner side of the body 2. A compression spring 122 is installed inside the fixed groove 121. A blocking plate 123 is slidably connected inside the fixed groove 121 through the compression spring 122. A pressure chamber 124 is fixedly connected through the bottom of the fixed groove 121. A piston is slidably connected to a pressure rod 125 inside one end of the pressure chamber 124. The end of the pressure rod 125 away from the pressure chamber 124 is fixedly connected to... Arc-shaped block A126, and push rod 127 are slidably connected to the piston inside the other end of the air pressure chamber 124. Arc-shaped block B128 is fixedly connected to the surface of the driven shaft 92. A extraction mechanism 11 is provided on the top of the base plate 1. The end of the push rod 127 away from the air pressure chamber 124 is fixedly connected to the bottom of the blocking plate 123. The shaking mechanism 10 includes a rotating gear 101, a slide rod 102, and a hydraulic chamber 105. The rotating gear 101 is fixedly connected to the surface of the drive shaft 91, and the slide rod 102 is fixedly connected to the hydraulic chamber 105. Inside the bottom of the second waste liquid tank 7, a screen 103 is slidably connected to the surface of a slide rod 102. A return spring 104 is sleeved on the surface of the slide rod 102. A hydraulic chamber 105 passes through and is fixedly connected to the top of the second discharge plate 6. A push rod 106 is slidably connected to a piston inside one end of the hydraulic chamber 105. A gear 108 is fixedly connected to the end of the push rod 106 away from the hydraulic chamber 105. The rotating gear 101 is an incomplete gear, and the teeth on the rotating gear 101 initially mesh with the teeth on the gear 108. When the rotating gear 101 rotates initially, it drives the gear 108 to move upward. A connecting rod 107 is slidably connected to a piston inside the other end of the hydraulic chamber 105. The end of the connecting rod 107 away from the hydraulic chamber 105 is fixedly connected to the bottom of the screen 103. The two ends of the return spring 104 abut against the bottom of the second waste liquid tank 7 and the bottom of the screen 103, respectively. When the connecting rod 107 moves downward, it drives the screen 103 to move downward, and the return spring 104 is compressed.

[0028] In this embodiment, the entire device is installed next to the CNC machine tool. The cutting fluid mixed with waste chips will be discharged to the top of the first feed plate 3 and flow along the first feed plate 3 to the support plate 4. The cutting fluid falls into the first waste liquid tank 5 through the filter screen 97 for collection, which is convenient for subsequent recycling. The waste chips remain on the filter screen 97. At this time, the first motor 96 can be turned on. The first motor 96 drives the drive shaft 91 to rotate through the output shaft. The rotation of the drive shaft 91 drives the driven shaft 92 to rotate through the transmission belt 93. The connecting block 94 moves with the transmission belt 93. The movement of the connecting block 94 drives the brush 95 to move. The moving brush 95 drives the waste on the surface of the filter screen 97 towards the second feed plate 6, resulting in good waste removal and minimal impact on waste movement. Subsequently, the waste on the second feed plate 6 slides onto the screen 103. The rotation of the drive shaft 91 also drives the rotating gear 101. Initially, the rotating gear 101 drives the rack 108 upward, which in turn drives the push rod 106 upward. The upward movement of the push rod 106, via hydraulic pressure within the hydraulic chamber 105, drives the connecting rod 107 downward, which in turn moves the screen 103. 03 moves downwards, compressing the return spring 104. When the rotating gear 101 rotates to the toothless part and disengages from the rack 108, the return spring 104 rebounds, causing the screen 103 to spring back to its original position. This cycle repeats, causing the waste chips on the screen 103 to shake, dislodging the residual cutting fluid on the waste chips into the second waste fluid tank 7 for collection. The rotation of the driven shaft 92 also drives the arc block B128 to rotate. During the rotation of the arc block B128, it will squeeze the arc block A126, causing the pressure rod 125 to move into the air pressure chamber 124. When 25 moves into the air chamber 124, the air pressure inside the air chamber 214 will drive the push rod 127 to move upward. The upward movement of the push rod 127 will drive the blocking plate 123 to move upward, and the compression spring 122 will be stretched. When the arc block B128 leaves the arc block A126, the compression spring 122 will rebound, causing the blocking plate 123 and the push rod 127 to move downward to return to their original positions. Meanwhile, the air pressure will drive the pressure rod 125 and the arc block A126 to move in the opposite direction to return to their original positions. The intermittent rise of the blocking plate 123 will block the cutting fluid and prevent too much cutting fluid from flowing down in a short time, thus affecting the filtration of the filter screen 97.

[0029] Example 2 like Figures 1-9As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes an extraction mechanism 11 including a second motor 111, a rotating rod 112, and a piston cylinder 114. The second motor 111 is fixedly installed at the front end of the machine body 2. The rotating rod 112 is rotatably connected to the inner side of the machine body 2. A cam 113 is fixedly connected to the surface of the rotating rod 112. The piston cylinder 114 is fixedly connected to the top of the base plate 1. A telescopic spring 115 is provided inside the piston cylinder 114. A piston rod 116 is slidably connected inside the piston cylinder 114 through the telescopic spring 115. A pressure plate 117 is fixedly connected to the top of the piston rod 116. The pressure plate 117 is located directly below the cam 113. The end of the cam 113 away from the rotating rod 112 is provided with grease. When the cam 113 rotates with the rotating rod 112, it will repeatedly squeeze the pressure plate 117. As it moves downwards, the lubricating grease can reduce wear. A suction pipe 118 and a delivery pipe 119 are respectively connected and fixedly connected to both sides of the piston cylinder 114. Both the suction pipe 118 and the delivery pipe 119 are equipped with one-way valves. The one-way valve in the suction pipe 118 is unidirectionally directed towards the inside of the piston cylinder 114. The end of the suction pipe 118 away from the piston cylinder 114 is connected and fixedly connected to the second waste liquid tank 7. When a negative pressure is formed inside the piston cylinder 114, the suction pipe 118 will draw the cutting fluid from the second waste liquid tank 7. The end of the delivery pipe 119 away from the piston cylinder 114 is connected and fixedly connected to the first waste liquid tank 5. The one-way valve in the delivery pipe 119 is unidirectionally directed towards the inside of the first waste liquid tank 5. When the cutting fluid inside the piston cylinder 114 is squeezed, it will be discharged into the first waste liquid tank 5 through the delivery pipe 119.

[0030] In this embodiment, when the second motor 111 is turned on, it drives the rotating rod 112 to rotate. When the cam 113 rotates with the rotating rod 112, it repeatedly squeezes the pressure plate 117, causing it to move downward. The downward movement of the pressure plate 117 drives the piston rod 116 to move downward, and the telescopic spring 115 is compressed. The downward movement of the piston rod 116 squeezes the cutting fluid in the piston cylinder 114, causing it to be discharged into the first waste liquid tank 5 through the infusion pipe 119. When the cam 113 leaves the pressure plate 117, the telescopic spring 115 rebounds, causing the piston rod 116 and the pressure plate 117 to move upward and return to their original positions. At this time, when a negative pressure is formed in the piston cylinder 114, the cutting fluid in the second waste liquid tank 7 is drawn in through the suction pipe 118. This cycle continues, and by transporting the cutting fluid to the first waste liquid tank 5 for centralized collection, the overall convenience of use is improved.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
