Description

Technical Field

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

[0002] Machine tool processing refers to the process of cutting a workpiece using cutting parts. Cutting parts can be used to process workpieces into different shapes, such as commonly used CNC machine tools. During the cutting process, a large number of chips will fall off the workpiece. These chips need to be removed in time using chip removal components. Commonly used chip removal components include chain plate components and screw conveyor components. The fallen chips can be transported by the chain plate to an external collection box for convenient centralized treatment.

[0003] Existing chain plate chip conveying assemblies include components such as a frame and chain plates. The chain plates are fixed inside the frame via tracks and rotating shafts. The chain plates can be rotated using an external drive component, moving the chips to the outside. Side chip deflectors are installed on the outside of the chain plates to reduce chip falling on both sides. However, the side deflectors in existing technologies are mostly fixed structures, meaning they are entirely fixed inside the frame and cannot move dynamically. Because the chain plates will dynamically shift when they move, a gap will appear between the chain plates and the chip deflectors. At this time, the chips can easily get stuck inside the gap, aggravating the wear of the chain plates.

[0004] In view of this, we propose a chip removal assembly for CNC machine tools. Utility Model Content

[0005] The purpose of this invention is to provide a chip removal component for CNC machine tools to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a chip removal assembly for CNC machine tools, including a frame, a drive assembly mounted on the outside of the frame, a chain belt meshing with the outside of the drive assembly, a chain plate installed between adjacent chain belts, and a cover plate detachably connected to the upper surface of the frame. A fixing frame is fixedly installed on the inner wall of the frame. A fixing plate is detachably connected to one side of the fixing frame. A support plate is fixedly installed on the outer surface of the fixing plate. A positioning rod is slidably connected inside the support plate. A spring is sleeved on the outside of the positioning rod. A clamping plate is fixedly installed at one end of the positioning rod, and a chip baffle is slidably connected to the outer surface of the clamping plate.

[0007] In this technical solution, the card plate can be used to position and fix the two ends of the chip baffle. At this time, the spring can push the chip baffle to stick to the outside of the chain plate. When the chain plate rotates, the chip baffle will always stick to both sides of the chain plate. Therefore, when the chain plate rotates and shifts to the left or right, the chip baffle can always play a role. At this time, the chip baffle can block the chips and reduce the falling of chips in the gaps on both sides.

[0008] In the above technical solution, one end of the cover plate is provided with a wedge-shaped collection port, one end of the frame is provided with a discharge port, and the upper and lower cover plates and the frame are connected by multiple sets of screws.

[0009] In this technical solution, the collection port and the discharge port are used for collection and discharge respectively, which can assist in the collection and discharge of debris.

[0010] In the above technical solution, further, the fixing plate is internally rotatably connected to a fixing screw, the outer surface of the fixing screw is threadedly connected to the inner surface of the fixing frame, the outer surface of the fixing plate is in contact with the inner wall of the frame, and the fixing plate and the fixing frame are respectively installed at both ends of the chip baffle plate.

[0011] In this technical solution, the fixing screw can fix the fixing plate and the chip baffle plate.

[0012] In the above technical solution, a connecting plate is fixedly installed on the outer surface of the support plate, and a limiting plate is fixedly installed at one end of the connecting plate, forming a T-shaped structure with the connecting plate and the limiting plate.

[0013] In this technical solution, the connecting plate and the limiting plate can move with the support plate and can position the mounting plate.

[0014] In the above technical solution, further, an installation plate is fixedly installed on the outer surface of the card plate, a limiting groove is opened inside the installation plate, the connecting plate slides inside the limiting groove, and the installation plate is located between the support plate and the limiting plate.

[0015] In this technical solution, the mounting plate can be used to position the card and control its linear movement.

[0016] In the above technical solution, one end of the spring is fixedly installed on the outer surface of the support plate, the other end of the spring is fixedly installed on the outside of the clamping plate, and a baffle is fixedly installed on one end of the positioning rod.

[0017] In this technical solution, the spring can push the clamping plate to move and control the position of the chip baffle.

[0018] In the above technical solution, a ceramic plate is further installed on one side of the chip baffle, and the ceramic plate is attached to the chain plate.

[0019] In this technical solution, the use of ceramic plates can enhance the effectiveness of the chip baffle and reduce frictional wear between the chain plate and the chip baffle.

[0020] The beneficial effects of this utility model are: 1. This chip removal assembly for CNC machine tools uses a spring and a clamping plate to fix the clamping plate in place. The clamping plate enters the interior of the chip baffle plate, and the two ends of the chip baffle plate are fixed by the limiting action of the clamping plates on both sides. At this time, the chip baffle plate is fixed to the outside of the chain plate and fits against the chain plate. When the chain plate moves dynamically, the spring can push the chip baffle plate to move dynamically, always keeping the chip baffle plate in contact with the outside of the chain plate, reducing the jamming of chips in the gap, and realizing the dynamic movement of the chip baffle plate, which helps to compensate for the offset gap between the chain plate and the chip baffle plate.

[0021] 2. The chip removal assembly for this CNC machine tool, by setting components such as a fixing screw and a connecting plate, allows the fixing plate to be adjusted in position using the fixing screw. In this case, the fixing plate can fix the chip baffle plate, and in the opposite case, the chip baffle plate can be quickly disassembled. Thus, after removing the cover plate, the chip baffle plate can be disassembled and replaced, which is convenient for replacement and maintenance. Attached Figure Description

[0024] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0025] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0026] Example 1: This example provides a chip removal assembly for a CNC machine tool, including a frame 1, a drive assembly 2 installed on the outside of the frame 1, a chain belt 3 meshing with the outside of the drive assembly 2, chain plates 4 installed between adjacent chain belts 3, and a cover plate 5 detachably connected to the upper surface of the frame 1. A fixed frame 6 is fixedly installed on the inner wall of the frame 1. A fixed plate 7 is detachably connected to one side of the fixed frame 6. A support plate 8 is fixedly installed on the outer surface of the fixed plate 7. A positioning rod 9 is slidably connected inside the support plate 8. A spring 10 is sleeved on the outside of the positioning rod 9. A clamping plate 11 is fixedly installed at one end of the positioning rod 9, and a chip baffle 12 is slidably connected to the outer surface of the clamping plate 11.

[0027] The clip plate 11 can be used to position and fix the two ends of the chip baffle 12. At this time, the spring 10 can push the chip baffle 12 to stick to the outside of the chain plate 4. When the chain plate 4 rotates, the chip baffle 12 will always stick to both sides of the chain plate 4. Therefore, when the chain plate 4 rotates and shifts to the left or right, the chip baffle 12 can always play a role. At this time, the chip baffle 12 can block the chips and reduce the chips falling into the gaps on both sides. The fixing plate 7 can be fixed by the fixing bracket 6. When the fixing plate 7 is attached to the fixing bracket 6, the lateral position of the clamping plate 11 is fixed. Conversely, after the chip baffle 12 is installed inside the frame 1, the clamping plate 11 enters the inside of the chip baffle 12. At this time, the two sets of clamping plates 11 can fix the two sides of the chip baffle 12. At this time, the chip baffle 12 will be attached to the outside of the chain plate 4 under the push of the spring 10 on one side. When the chain plate 4 is dynamically offset, the chip baffle 12 can adjust its position in real time and make up for the offset gap. At this time, the external debris is not easy to fall out through the gap.

[0028] Example 2: This example provides a chip removal assembly for CNC machine tools. In addition to the technical solutions of the above examples, it also has the following technical features: a wedge-shaped collection port 13 is provided at one end of the cover plate 5, a discharge port 14 is provided at one end of the frame 1, and the upper and lower cover plates 5 and the frame 1 are connected by multiple sets of screws.

[0029] Among them, the collection port 13 and the discharge port 14 are used for collection and discharge, respectively, which can assist in the collection and discharge of debris; The collection port 13 and the discharge port 14 are respectively located at both ends of the frame 1. When the frame 1 is pushed into the machine tool, the debris can fall into the collection port 13. After being conveyed by the internal chain plate 4, it can be discharged through the discharge port 14. The cover plate 5 is fixed to the frame 1 by the screws on the corners and can be disassembled.

[0030] Example 3: This example provides a chip removal assembly for CNC machine tools. In addition to the technical solutions of the above examples, it also has the following technical features: a fixing screw 15 is rotatably connected inside the fixing plate 7; the outer surface of the fixing screw 15 is threadedly connected to the inside of the fixing frame 6; the outer surface of the fixing plate 7 is in contact with the inner wall of the frame 1; and the fixing plate 7 and the fixing frame 6 are respectively installed at both ends of the chip baffle plate 12.

[0031] The fixing screw 15 can fix the fixing plate 7 and the chip baffle plate. By rotating the fixing screw 15, the fixing frame 6 and the fixing plate 7 can be brought closer together. At this time, the clamping plate 11 will move with the fixing plate 7 and the support plate 8. The clamping plate 11 is placed inside the chip baffle and pushed in from both sides. At this time, the L-shaped structure formed by the clamping plate 11 and the positioning rod 9 can fix the chip baffle 12. Conversely, the chip baffle 12 can be disassembled after the cover plate 5 is removed.

[0032] Example 4: This example provides a chip removal assembly for CNC machine tools. In addition to the technical solutions of the above examples, it also has the following technical features: a connecting plate 16 is fixedly installed on the outer surface of the support plate 8, and a limiting plate 17 is fixedly installed at one end of the connecting plate 16. The connecting plate 16 and the limiting plate 17 form a T-shaped structure.

[0033] Among them, the connecting plate 16 and the limiting plate 17 can move with the support plate 8 and can position the mounting plate 18. The connecting plate 16 and the limiting plate 17 form an installation groove on the outside of the support plate 8. At this time, the mounting plate 18 can move inside the installation groove and will not lose contact with the outside of the support plate 8.

[0034] Example 5: This example provides a chip removal assembly for CNC machine tools. In addition to the technical solutions of the above examples, it also has the following technical features: an mounting plate 18 is fixedly installed on the outer surface of the clamping plate 11, a limiting groove 19 is opened inside the mounting plate 18, the connecting plate 16 slides inside the limiting groove 19, and the mounting plate 18 is located between the support plate 8 and the limiting plate 17.

[0035] The mounting plate 18 can be used to position the card plate 11 and control the linear movement of the card plate 11. The mounting plate 18 and the positioning rod 9 are arranged in parallel. The mounting plate 18 can limit the movement of the clamping plate 11. At this time, the mounting plate 18 can move linearly under the action of the positioning rod 9 and the clamping plate 11. With the help of the clamping plate 11, the chip baffle 12 can be controlled to move linearly. At this time, the chip baffle 12 will fit against both sides of the chain plate 4.

[0036] Example 6: This example provides a chip removal assembly for CNC machine tools. In addition to the technical solutions of the above examples, it also has the following technical features: one end of the spring 10 is fixedly installed on the outer surface of the support plate 8, the other end of the spring 10 is fixedly installed on the outside of the clamping plate 11, and one end of the positioning rod 9 is fixedly installed with a baffle 20.

[0037] Among them, the spring 10 can push the card plate 11 to move and can control the position of the chip baffle 12; The baffle 20 can limit one end of the positioning rod 9. At this time, the spring 10 can push the clamping plate 11 to move outward. Since the clamping plate 11 fixes the chip baffle 12 inside the frame 1, the chip baffle 12 will fit against the outer side of the chain plate 4 when the clamping plate 11 moves in a straight line.

[0038] Example 7: This example provides a chip removal assembly for CNC machine tools. In addition to the technical solutions of the above examples, it also has the following technical features: a ceramic plate 21 is installed on one side of the chip baffle, and the ceramic plate 21 is attached to the chain plate 4.

[0039] Among them, the use of ceramic plate 21 can increase the performance of chip baffle 12 and reduce frictional wear between chain plate 4 and chip baffle 12. The ceramic plate 21 is fixed to one side of the chip baffle 12 by adhesive. The interior of the ceramic plate 21 is mainly composed of aluminum oxide, which has high wear resistance and is suitable for high-hardness chip scenarios such as titanium alloy and quenched steel.

[0040] Working principle: When installing the chip baffle 12, open the cover plate 5, then control the fixing plate 7 and the fixing bracket 6 to move away, and clamp the clamping plate 11 at both ends of the chip baffle 12. Then, control the fixing plate 7 and the fixing bracket 6 to move closer through the fixing screw 15. At this time, the clamping plate 11 can enter both ends of the chip baffle 12 to fix the chip baffle 12. Under the push of the spring 10, the clamping plate 11 drives the chip baffle 12 to move. At this time, the chip baffle 12 can fit against the outer side of the chain plate 4. When the chain plate 4 is dynamically offset, the chip baffle 12 will dynamically fit against the chain plate 4, reducing the falling of debris in the gap.
