Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a chip removal device for CNC machine tools. Background Technology

[0002] CNC machine tools, with their significant advantages of high precision, high efficiency, and high degree of automation, have become core equipment for the processing and manufacturing of various parts, and are widely used in many key industries such as automobile manufacturing, aerospace, and mold processing. During operation, CNC machine tools inevitably generate a large amount of waste chips due to the high-speed cutting and grinding operations performed by the cutting tools and workpieces. If these waste chips are not removed and properly handled in a timely and effective manner, they will have many adverse effects on the normal operation of the machine tool, processing quality, and the production environment.

[0003] Currently, existing chip removal equipment on the market primarily focuses on removing and collecting waste chips generated inside machine tools, which alleviates the obstruction caused by chip accumulation to machine tool operation to some extent. However, in actual production applications, the waste chips generated by machine tool processing include clumps of chips and fine fragments. Clumps of chips, due to their large volume and loose structure, not only occupy a lot of space during collection but also hinder subsequent transportation and reprocessing. Fine fragments, on the other hand, have a large surface area, making them highly susceptible to adsorbing cutting fluid and various oils used in the machining process. The mixing of clumps of chips and fine fragments further complicates subsequent recycling and processing.

[0004] Therefore, it is necessary to provide a new chip removal device for CNC machine tools to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a chip removal device for CNC machine tools.

[0006] The CNC machine tool chip removal device provided by this utility model includes: a machine tool body, a hopper, a drive assembly, a sieve plate, a compaction plate, and a top extension assembly. A chip removal belt is installed on one side of the machine tool body, and a collection box is provided on one side of the chip removal belt. A hopper is provided below the discharge end of the chip removal belt. A drive assembly is installed between the collection box and the hopper. The drive assembly drives the hopper to move back and forth to evenly spread the discharged waste chips inside the collection box. A sieve plate for screening waste chips is installed inside the collection box. A compaction plate is installed inside the collection box. A top extension assembly is installed between the collection box and the compaction plate. The top extension assembly drives the compaction plate to move to compact the clumps of waste chips after screening.

[0007] Preferably, the drive assembly includes: a motor, a reciprocating lead screw, and a limiting rod. The motor is fixedly connected to the top of the collection box, and the output end of the motor is fixedly connected to the reciprocating lead screw. Both ends of the reciprocating lead screw are rotatably connected to the top of the collection box. A slider is installed on the outer wall of the reciprocating lead screw. The side wall of the slider is fixedly connected to the hopper. An installation block is fixedly connected to the side wall of the hopper. A limiting rod is fixedly connected to the top of the collection box. The limiting rod is placed inside the installation block and slidably connected to its inner wall.

[0008] Preferably, a cylinder is fixedly connected to the side wall of the collection box, the output end of the cylinder is fixedly connected to the end of the sieve plate, a spring is fixedly connected to the other end of the sieve plate, and a mounting plate is fixedly connected to the other end of the spring. Both ends of the mounting plate are fixedly connected to the side wall of the collection box.

[0009] Preferably, the top extension assembly includes a hydraulic push rod, which is fixedly connected to the top of the collection box, and the output end of the hydraulic push rod extends into the interior of the collection box and is fixedly connected to the compaction plate.

[0010] Preferably, two collection boxes are symmetrically slidably installed inside the collection box, one located directly below the sieve plate and the other directly below the compaction plate.

[0011] Preferably, a baffle is slidably connected to the inner wall of the middle part of the collection box, and a baffle rod is symmetrically fixedly connected to the side wall of the baffle near the upper position and in contact with the top of the compaction plate. A pressure rod is fixedly connected to the side wall of the baffle near the lower position, and the side wall of the compaction plate is provided with a relief groove corresponding to the pressure rod.

[0012] Preferably, the clearance groove has an installation groove inside, and a spring is fixedly connected to the inner wall of the installation groove. A trapezoidal block is fixedly connected to the other end of the spring, and the trapezoidal block is slidably connected to the inner wall of the installation groove.

[0013] Compared with related technologies, the chip removal device for CNC machine tools provided by this utility model has the following beneficial effects: The high-frequency vibration of the sieve plate driven by the cylinder efficiently separates fine debris from clumps of waste. Fine debris falls through the sieve holes into the collection box below, while clumps of waste are intercepted and guided to the compaction area. This physical sieving method requires no manual intervention and avoids the problem of fine debris adsorbing cutting fluid and contaminating clumps of waste when traditional mixed collection is used, so that both types of waste can remain relatively clean. Hydraulic push rods drive compaction plates to apply pressure to clumps of waste, which can compact loose clumps of waste and reduce the space occupied; this extends the cycle of the collection box being filled, reduces the number of cleanings, and improves the overall efficiency of the production line; during the compaction process, trapezoidal blocks drive pressure rods and baffles to move down synchronously until they contact the screen plate, forming a closed compaction zone, which prevents waste from the screen plate from entering the compaction zone, reducing the need for cleaning and maintenance inside the equipment; The motor drives the reciprocating screw to rotate, causing the hopper to move back and forth in a straight line along the width of the collection box. The waste chips discharged by the chip conveyor belt are evenly scattered on the screen plate through the hopper, which avoids the problem of excessive accumulation of waste chips directly below the discharge end and empty edge areas. It also prevents the screen plate from being clogged due to local overload, ensuring the continuous effectiveness of the screening function. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figures 1 to 6A chip removal device for CNC machine tools is disclosed. The device comprises: a machine tool body 1, a hopper 4, a drive assembly, a sieve plate 5, a compaction plate 6, and a top extension assembly. A chip removal belt 2 is installed on one side of the machine tool body 1, and a collection box 3 is provided on one side of the chip removal belt 2. The hopper 4 is located below the discharge end of the chip removal belt 2. A drive assembly is installed between the collection box 3 and the hopper 4, driving the hopper 4 to reciprocate and evenly distribute the discharged chips inside the collection box 3. A sieve plate 5 for screening chips is installed inside the collection box 3, and a compaction plate 6 is installed inside the collection box 3. A top extension assembly is installed between the collection box 3 and the compaction plate 6, driving the compaction plate 6 to move and compact the clumps of screened chips. The drive assembly includes a motor 7. A reciprocating screw 8 and a limiting rod 9 are provided. A motor 7 is fixedly connected to the top of the collection box 3. The output end of the motor 7 is fixedly connected to the reciprocating screw 8. Both ends of the reciprocating screw 8 are rotatably connected to the top of the collection box 3. A slider 10 is installed on the outer wall of the reciprocating screw 8. The side wall of the slider 10 is fixedly connected to the hopper 4. An installation block is fixedly connected to the side wall of the hopper 4. A limiting rod 9 is fixedly connected to the top of the collection box 3. The limiting rod 9 is placed inside the installation block and is slidably connected to its inner wall. A cylinder 11 is fixedly connected to the side wall of the collection box 3. The output end of the cylinder 11 is fixedly connected to the end of the screen plate 5. A spring 12 is fixedly connected to the other end of the screen plate 5. An installation plate is fixedly connected to the other end of the spring 12. Both ends of the installation plate are fixedly connected to the side wall of the collection box 3.

[0019] It should be noted that: the sieve plate 5 is designed to be inclined, and the clumps of waste debris intercepted move along its incline toward the collection box 14 below the compaction plate 6; the cylinder 11 is activated, and its output end drives the sieve plate 5 to move back and forth rapidly in the horizontal direction; the other end of the sieve plate 5 is connected to the mounting plate through a spring 12. When the piston rod of the cylinder 11 extends, the spring 12 is compressed; when the piston rod retracts, the spring 12 elastically returns to its original position, assisting the sieve plate 5 to vibrate at high frequency; fine debris falls through the sieve holes into the collection box 14 directly below the sieve plate 5 under the action of vibration; the clumps of waste debris are intercepted by the sieve plate 5 and move toward the middle of the collection box 3 with the vibration of the sieve plate 5, and finally fall into the collection box 14 directly below the compaction plate 6.

[0020] Please see Figure 5 and Figure 6The top extension assembly includes: a hydraulic push rod 13, which is fixedly connected to the top of the collection box 3. The output end of the hydraulic push rod 13 extends into the interior of the collection box 3 and is fixedly connected to the compaction plate 6. Two collection boxes 14 are symmetrically and slidably installed inside the collection box 3, one of which is located directly below the sieve plate 5 and the other is located directly below the compaction plate 6. A baffle 15 is slidably connected to the inner wall of the middle part of the collection box 3. A baffle rod 16 is symmetrically and fixedly connected to the side wall of the baffle 15 near the upper position and contacts the top of the compaction plate 6. A pressure rod 17 is fixedly connected to the side wall of the baffle 15 near the lower position. A clearance groove corresponding to the pressure rod 17 is opened on the side wall of the compaction plate 6. An installation groove is opened inside the clearance groove. A spring 18 is fixedly connected to the inner wall of the installation groove. A trapezoidal block 19 is fixedly connected to the other end of the spring 18 and is slidably connected to the inner wall of the installation groove. It should be noted that: when the hydraulic push rod 13 is activated, its output end drives the compaction plate 6 to move vertically downward; during the downward movement of the compaction plate 6, the trapezoidal block 19 on its side wall first contacts the pressure rod 17 on the baffle 15; pushing the pressure rod 17 downward, causing the baffle 15 to slide down synchronously along the inner wall of the collection box 3; when the baffle 15 descends to contact the upper surface of the sieve plate 5, it stops moving downward, and the compaction plate 6 continues to move downward, the pressure rod 17 squeezes the trapezoidal block 19, causing it to overcome the elastic force of the second spring 18 and retract into the mounting groove until the trapezoidal block 19 is completely retracted into the mounting groove, the pressure rod 17 passes through the clearance groove, the second spring 18 releases its elastic force, and pushes the trapezoidal block 19 to reset; at this time, the compaction plate 6 continues to move downward and contacts the clumps of waste below, and continues to apply pressure to compact the loose clumps of waste.

[0021] The working principle of the chip removal device for CNC machine tools provided by this utility model is as follows: The waste chips generated during processing by the machine tool body 1 fall onto the chip conveyor belt 2 on one side of the machine tool body 1. The chip conveyor belt 2 starts to operate, conveying the waste chips towards the collection box 3, and finally discharging them from the discharge end of the chip conveyor belt 2. Simultaneously, the motor 7 in the drive assembly starts, and the output end of the motor 7 drives the reciprocating screw 8 to rotate. Since the reciprocating screw 8 is installed in conjunction with the slider 10, and the side wall of the slider 10 is fixedly connected to the feeding hopper 4, and the mounting block on the side wall of the feeding hopper 4 is slidably connected to the limit rod 9, the slider 10 drives the feeding hopper 4 to make linear reciprocating motion along the axis of the reciprocating screw 8. The waste chips discharged from the chip conveyor belt 2 fall into the reciprocating feeding hopper 4. The feeding hopper 4 evenly throws the waste chips onto the screen plate 5 inside the collection box 3 through the reciprocating motion, avoiding the local accumulation of waste chips on the screen plate 5. While the waste material is being distributed, the cylinder 11 on the side wall of the collection box 3 is activated, and its output end drives the screen plate 5 to move back and forth rapidly in the horizontal direction. The other end of the screen plate 5 is connected to the mounting plate through a spring 12. When the piston rod of the cylinder 11 extends, the spring 12 is compressed. When the piston rod retracts, the spring 12 returns to its elastic state, assisting the screen plate 5 to vibrate at high frequency. Under the action of vibration, fine debris falls through the screen holes into the collection box 14 directly below the screen plate 5. Clumps of waste material are intercepted by the screen plate 5 and move towards the middle of the collection box 3 with the vibration of the screen plate 5, and finally fall into the collection box 14 directly below the compaction plate 6. The two collection boxes 14 temporarily store fine debris and clumps of waste, respectively, to achieve preliminary classification of waste. The hydraulic push rod 13 in the top extension assembly starts according to a preset time, and its output end drives the compaction plate 6 to move vertically downward. During the downward movement of the compaction plate 6, the trapezoidal block 19 on its side wall first contacts the pressure rod 17 on the baffle 15. Due to the force on the inclined surface of the trapezoidal block 19, the pressure rod 17 is pushed downward, which drives the baffle 15 to slide down synchronously along the inner wall of the collection box 3. When the baffle 15 descends to contact the upper surface of the screen plate 5, it stops moving downward, blocking the channel between the screen plate 5 and the compaction area, and preventing waste from entering during the compaction process. As the compaction plate 6 continues to move downward, the pressure rod 17 presses against the trapezoidal block 19, causing it to retract into the mounting groove against the elastic force of the second spring 18, until the trapezoidal block 19 is completely retracted into the mounting groove. The pressure rod 17 then passes through the clearance groove, and the second spring 18 releases its elastic force, pushing the trapezoidal block 19 back to its original position. At this time, the compaction plate 6 continues to move downward and comes into contact with the clump of waste below, and continues to apply pressure to compact the loose clump of waste. After compaction is completed, the hydraulic push rod 13 drives the compaction plate 6 to move upward; at this time, the pressure rod 17 enters the clearance groove, and the trapezoidal block 19 pushes the pressure rod 17 to move upward, driving the baffle 15 to reset synchronously; when the baffle 15 is fully reset, the compaction plate 6 continues to move upward, and the pressure rod 17 squeezes the trapezoidal block 19 again to shrink it until the trapezoidal block 19 disengages from the pressure rod 17. The spring 18 releases its elastic force to push the trapezoidal block 19 to reset. At this time, the top of the compaction plate 6 contacts the stop rod 16 on the baffle 15, completing the entire reset process, and waiting for the next compaction cycle.
