Description

Technical Field

[0001] This utility model relates to the field of boring and milling machine technology, and in particular to an automatic chip removal mechanism for a floor-type boring and milling machine. Background Technology

[0002] In fields such as mechanical manufacturing, floor-type boring and milling machines are often used to process large and heavy parts. As a key processing equipment, they can perform operations such as boring, milling, drilling, and threading, completing the machining tasks of high-precision holes, complex planes, and curved surfaces of large parts, effectively meeting the precision and efficiency requirements of large equipment manufacturing.

[0003] A Chinese utility model patent with authorization announcement number CN216463370U and patent name "A Chip Removal Mechanism for a Floor-type Boring and Milling Machine" discloses a chip removal mechanism for a floor-type boring and milling machine. The mechanism includes a machine body connected to a boring and milling mechanism capable of vertical movement. A worktable is located below the boring and milling mechanism, and multiple fixed slots are provided on the worktable. These slots are arranged in parallel, with both ends of each slot penetrating the worktable. A chip removal cavity, square in shape, is located below the fixed slots. Each fixed slot has a discharge hole connected to the chip removal cavity. A connecting channel is located below the chip removal cavity, with one end connected to the chip removal cavity and the other end bent and penetrating the side of the worktable. An exhaust fan is connected to the end of the connecting channel away from the chip removal cavity, and a collection pipe is connected to the exhaust fan. A collection box is connected to the end of the collection pipe away from the exhaust fan.

[0004] However, floor-type boring and milling machines generate a large amount of metal shavings during machining. If these shavings are not cleaned in time, they will accumulate on the worktable, affecting the positioning and clamping accuracy of the workpiece and leading to machining errors. Furthermore, the shavings may enter critical components such as the machine tool's guide rails and lead screws, accelerating wear, shortening the machine tool's lifespan, and increasing maintenance costs. In addition, manual cleaning of metal shavings is not only inefficient but may also pose safety hazards to operators. Utility Model Content

[0005] The purpose of this invention is to provide an automatic chip removal mechanism for a floor-type boring and milling machine, which has the effects of automatically cleaning iron chips during machining, improving the comprehensiveness of iron chip cleaning, and improving the chip collection efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic chip removal mechanism for a floor-type boring and milling machine, comprising a machine body, wherein the machine body is connected to a movable boring and milling mechanism, a worktable is provided below the boring and milling mechanism, a chip removal cavity is provided in the worktable, a material unloading component and a material collecting component are provided in the chip removal cavity, the material unloading component includes a workpiece support, the material collecting component includes a scraper, a driving component and a collecting component, the driving component controls the scraper to move along the upper surface of the workpiece support, and the collecting component is located at the bottom of the worktable.

[0007] By adopting the above technical solution, when the workpiece is placed on the workpiece support for processing, the iron filings generated on the workpiece fall from the annular area between the workpiece support and the chip removal cavity into the collection device at the bottom of the worktable. In addition, when the drive unit moves the scraper on the surface of the workpiece support, the scraper pushes and collects the residual iron filings, which then fall into the collection device, thus achieving the effect of automatically cleaning iron filings during processing and improving the comprehensiveness of iron filings cleaning.

[0008] A further feature of this invention is that the workpiece support is frustum-shaped, and the chip removal cavity includes a cylindrical groove and a collection groove that are interconnected.

[0009] A further feature of this invention is that the workpiece support is disposed within a cylindrical groove, the workpiece support and the cylindrical groove being coaxial; the driving component includes a drive motor, which is disposed at the bottom of the workpiece support. A further feature of this invention is that the scraper includes a rotating part and a scraping part; one end of the rotating part is radially fixedly connected to the output end of the drive motor; the bottom end of the scraping part is fixedly connected to the end of the rotating part away from the drive motor; and the scraping part contacts the upper surface of the workpiece support.

[0010] A further feature of this invention is that the workpiece support has several openings radially formed.

[0011] By adopting the above technical solution, the drive motor causes the rotating part of the scraper to rotate, and the rotating part drives the scraping part to rotate in contact with the upper surface of the frustum-shaped workpiece support, pushing the residual iron filings to several openings on the workpiece support, so that they fall into the collection container, thereby improving the comprehensiveness of iron filings cleaning.

[0012] A further feature of this invention is that the two sides of the workpiece support are fixedly connected to the cylindrical groove via connecting rods.

[0013] A further feature of this invention is that the upper surface of the connecting rod is provided with an inclined slope with a triangular cross-section.

[0014] By adopting the above technical solution, the connecting rod is designed with an inclined slope. When iron filings fall onto the connecting rod, they will slide down the inclined slope under the action of gravity and fall into the collection device in a unified manner. There is no need to add too many collection devices, which avoids the accumulation of iron filings on the connecting rod and greatly improves the iron filings collection efficiency.

[0015] A further feature of this invention is that the collecting component is a collecting box, which is slidably disposed inside the collecting trough.

[0016] By adopting the above technical solution, the collection box collects the falling iron filings, and the sliding mechanism allows for convenient removal and return for reuse, which is beneficial for the centralized subsequent processing of the iron filings.

[0017] A further feature of this invention is that a filter screen is provided on one side of the collection box, and an exhaust fan with an exhaust port corresponding to the position of the filter screen is provided on the worktable.

[0018] By adopting the above technical solution, the exhaust fan motor drives the blades to rotate and form a high-speed airflow. The high-speed airflow generates negative pressure. Under the action of negative pressure suction, the iron filings generated during processing move from the processing area to the exhaust port, and are then intercepted by the filter screen and fall into the collection box at the bottom of the workbench. One side of the collection box is sealed by the filter screen, so that when the collection box is taken out from the side of the workbench, the filter screen can prevent the iron filings from falling.

[0019] In addition, compared with traditional chip removal holes, the suction force of the exhaust fan is more uniform and stable in the annular area between the workpiece support and the cylindrical groove. The airflow can flow more evenly along the annular area, thereby generating a more concentrated suction force on the iron chips in the entire circumferential direction. This allows the iron chips to be more evenly adsorbed and sucked away along the annular area, falling into the collection box.

[0020] A further feature of this invention is that the top of the workpiece support is provided with a support surface, and an electromagnet is provided inside the support surface.

[0021] By adopting the above technical solution, the workpiece is placed on the support surface of the workpiece support platform, and the electromagnet is energized to generate an attraction force, ensuring that the workpiece is placed stably.

[0022] The beneficial effects of this utility model are:

[0023] 1. When the workpiece is placed on the workpiece support for processing, the iron filings generated on the workpiece fall from the annular area between the workpiece support and the chip removal cavity into the collection unit at the bottom of the worktable. In addition, when the drive unit moves the scraper on the surface of the workpiece support, the scraper pushes the residual iron filings to fall into the collection unit, thus achieving the effect of automatically cleaning iron filings during processing and improving the comprehensiveness of iron filings cleaning.

[0024] 2. The drive motor makes the rotating part of the scraper rotate, and the rotating part drives the scraping part to rotate in contact with the upper surface of the frustum-shaped workpiece support, pushing the residual iron filings to several openings on the workpiece support, so that they fall into the collection container, thereby improving the comprehensiveness of iron filings cleaning.

[0025] 3. Compared with traditional chip removal holes, the annular area between the workpiece support and the cylindrical groove provides a more uniform and stable suction force from the exhaust fan. The airflow can flow more evenly along the annular area, thereby generating a more concentrated suction force on the iron chips in the entire circumferential direction. This allows the iron chips to be more evenly adsorbed and sucked away along the annular area, falling into the collection box.

[0026] 4. The connecting rod is designed with an inclined slope. When iron filings fall onto the connecting rod, they will slide down the inclined slope under the action of gravity and fall into the collection device in a unified manner. There is no need to add too many additional collection devices, which avoids the accumulation of iron filings on the connecting rod and greatly improves the iron filings collection efficiency.

[0027] 5. The collection box collects the falling iron filings, and the sliding mechanism allows for easy removal and return for reuse, which is beneficial for the centralized subsequent processing of iron filings.

[0028] 6. The exhaust fan motor drives the blades to rotate, creating a high-speed airflow. The high-speed airflow generates negative pressure. Under the suction of the negative pressure, the iron filings generated during processing move from the processing area to the exhaust port, and are then intercepted by the filter screen and fall into the collection box at the bottom of the workbench. One side of the collection box is sealed by the filter screen, so that when the collection box is removed from the side of the workbench, the filter screen can prevent the iron filings from spilling.

[0036] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] like Figure 1 , 2 As shown in Figures 3, 4, and 5, an automatic chip removal mechanism for a floor-type boring and milling machine includes a machine body 1. A movable boring and milling mechanism 2 is connected to the machine body 1. A worktable 3 is located below the boring and milling mechanism 2. A chip removal cavity is provided within the worktable 3, containing a material feeder and a material collector. The material feeder includes a workpiece support 4, and the material collector includes a scraper 5, a driving component, and a collecting component. The driving component controls the scraper 5 to move along the upper surface of the workpiece support 4, and the collecting component is located at the bottom of the worktable 3. Specifically, the machine body 1 is fixedly connected to the worktable 3. During the process of placing the workpiece on the workpiece support 4 and machining it, the iron filings generated by the workpiece fall from the annular area between the workpiece support 4 and the chip removal cavity into the collecting component at the bottom of the worktable 3. Simultaneously, the driving component drives the scraper 5 to move along the upper surface of the workpiece support 4, pushing residual iron filings into the collecting component, thus achieving automatic cleaning of iron filings during machining and improving the comprehensiveness of iron filings cleaning.

[0038] The workpiece support 4 is frustum-shaped. The chip removal cavity includes a cylindrical groove 31 and a collection groove 32 that are interconnected. The workpiece support 4 is set in the cylindrical groove 31 and is coaxial with the cylindrical groove 31. The driving component includes a drive motor 6, which is set at the bottom of the workpiece support 4. The scraper 5 includes a rotating part 51 and a scraping part 52. One end of the rotating part 51 is radially fixedly connected to the output end of the drive motor 6. The bottom end of the scraping part 52 is fixedly connected to the end of the rotating part 51 away from the drive motor 6. The scraping part 52 is in contact with the upper surface of the workpiece support 4. Several openings 41 are radially opened on the workpiece support 4. Specifically, the bottom of the workpiece support 4 has a groove for fixing and installing the drive motor 6. After the drive motor 6 starts, it drives the rotating part 51 of the scraper 5 to rotate. The rotating part 51 then drives the scraping part 52 to rotate and adhere to the upper surface of the frustum-shaped workpiece support 4. During this process, the scraping part 52 pushes the residual iron filings to several openings 41 on the workpiece support 4, so that the iron filings fall into the collection part, effectively improving the comprehensiveness of iron filings cleaning.

[0039] The workpiece support 4 is fixedly connected to the cylindrical groove 31 on both sides by connecting rods 7. The upper surface of the connecting rods 7 is provided with an inclined slope with a triangular cross-section. Specifically, the upper inclined slope is integrally formed with the main structure. When iron filings fall onto the connecting rods 7, they slide down along the inclined slope and fall smoothly into the collecting component without the need for additional collecting components. The collecting component is a collecting box 8, which is slidably installed inside the collecting groove 32. A filter screen 9 is provided on one side of the collecting box 8, and an exhaust fan 10 with an exhaust port corresponding to the position of the filter screen 9 is provided on the worktable 3. Specifically, the filter screen 9 is fixedly connected to the right side wall of the collection box 8, and the workbench 3 is fixedly connected to the exhaust fan 10. The filter screen 9 and the exhaust fan 10 are connected. The exhaust fan 10 generates suction, which drives the iron filings from the processing area to the exhaust port. After being intercepted by the filter screen 9, the iron filings fall into the collection box 8 at the bottom of the workbench 3, realizing automatic cleaning of iron filings during the processing. One side of the collection box 8 is closed by the filter screen 9. When it is taken out from the side of the workbench 3, the filter screen 9 prevents the iron filings from spilling, which is convenient for subsequent processing. In addition, compared with the traditional chip discharge hole, the annular area between the workpiece support 4 and the cylindrical groove 31 makes the suction of the exhaust fan 10 more concentrated in the entire circumferential direction. The iron filings are evenly adsorbed and fall into the collection box 8 along the annular area.

[0040] The top of the workpiece support 4 is provided with a support surface 42, and an electromagnet 43 is installed inside the support surface 42. Specifically, a cylindrical support surface 42 is fixedly connected to the top of the workpiece support 4. The top surface of the support surface 42 is a flat horizontal working surface. An electromagnet 43 is embedded inside the support surface 42. The top surface of the support surface 42 is flush with the top surface of the electromagnet 43. When the electromagnet 43 is energized, it attracts the workpiece, ensuring that the workpiece is stably placed on the workpiece support 4.

[0041] The working process of the automatic chip removal mechanism of this utility model floor-type boring and milling machine is as follows:

[0042] S1. First, energize the electromagnet 43 in the workpiece support 4 to attract and place the workpiece on the workpiece support 4. Move the boring and milling mechanism 2 on the machine body 1 to process the workpiece. Simultaneously turn on the exhaust fan 10. During processing, the exhaust fan 10 generates suction, driving iron filings from the annular area of ​​the workpiece support 4 and the cylindrical groove 31 and the opening 41 on the workpiece support 4 to the exhaust port. After being intercepted by the filter screen 9, the iron filings fall into the collection box 8 at the bottom of the worktable 3.

[0043] S2. During the process of iron filings falling into the collection box 8, some iron filings pass through the connecting rod 7 and slide down the inclined slope of the connecting rod 7 into the collection box 8 under the action of gravity.

[0044] S3. When the exhaust fan 10 is started, the drive motor 6 is started, which drives the rotating part 51 of the scraper 5 to rotate. The rotating part 51 then drives the scraping part 52 to rotate against the upper surface of the frustum-shaped workpiece support 4. The scraping part 52 pushes the residual iron filings to the opening 41 on the workpiece support 4, and the iron filings fall into the collection box 8 through the opening 41.

[0045] S4. After the workpiece processing is completed and the iron filings are cleaned, turn off the drive motor 6 and the exhaust fan 10, pull out the collection box 8 from the side, and perform further processing on the iron filings.
