Description

Technical Field

[0001] This utility model relates to the technical field of chip removal mechanisms, and in particular to a five-axis machining chip removal mechanism. Background Technology

[0002] There are many methods for processing mechanical parts in modern mechanical manufacturing. In addition to cutting, there are casting, forging, welding, stamping, extrusion, etc. However, for parts with high precision requirements and fine surface roughness requirements, they generally need to be finally processed by cutting on machine tools. Machine tools play an important role in the modernization of the national economy. In the process of processing products, modern machine tools generate a large amount of debris that falls onto the processing table. The existing technical publication number CN222588981U discloses a five-axis machine tool machining waste chip cleaning mechanism, which includes a rectangular table, with a left connecting table and a right connecting table on both sides of the rectangular table. The top surface of the left connecting table has a through-hole, and a dust collection hood is provided above the through-hole and on the top surface of the left connecting table. This application uses a dust removal fan to blow the waste chips on the rectangular table into the interior of the dust collection hood. The waste chips falling into the dust collection hood fall into the interior of the dust box through the through-hole, and then fall into the dust collection bag for centralized collection and treatment, ensuring a clean machining environment and reducing environmental pollution. The output end of the motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the moving block to move left and right along the horizontal direction of the threaded rod. At the same time, the slider on the bottom surface of the moving block moves inside the groove. The movement of the moving block drives the dust removal fan to move, and the movement of the dust removal fan expands the blowing range of the dust removal fan, improving the practicality of the device. However, its complex structure occupies workbench space, requires external force to drive, and makes it inconvenient to clean up chips that accumulate at the base of the turntable. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a five-axis machining chip removal mechanism with a simple structure, requiring no additional power drive, and capable of actively throwing chips to a predetermined chip removal area.

[0004] This utility model discloses a five-axis machining chip removal mechanism, including a rotary table, a fixed chip removal component, a centrifugal extension component, and a movable chip removal component. The fixed chip removal component is installed on the bottom right side of the rotary table, and the centrifugal extension component is installed on the bottom left side of the rotary table. The movable chip removal component is installed on the centrifugal extension component. When the rotary table rotates, the fixed chip removal component actively removes the chips that have accumulated in dead corners such as the root of the rotary table. At the same time, the centrifugal force generated by the rotation of the rotary table causes the centrifugal extension component to extend, and the movable chip removal component actively throws the chips to the predetermined chip removal area. The structure is simple and requires no additional power drive.

[0005] Preferably, the fixed chip removal component includes a fixed plate, multiple first support rods, and a first scraper. The fixed plate is bolted to the right side of the bottom of the rotary table. Multiple first support rods are installed at the bottom of the fixed plate, with the length of the bottom of the first support rods decreasing from left to right, and a first scraper is installed on each first support rod, making the first scraper inclined. When the rotary table rotates, the fixed plate and the first support rods drive the first scraper to rotate. The inclined first scraper can guide the chips, allowing the first scraper to actively discharge the chips accumulated at the root of the rotary table.

[0006] Preferably, the centrifugal extension component includes a slide rod, a limiting slide plate, a telescopic arm, and a spring. A telescopic groove is provided on the right side of the bottom of the rotary table. The slide rod is installed in the telescopic groove, and a limiting slide plate is installed on the left end of the slide rod. The telescopic arm is slidably installed in the telescopic groove, and the limiting slide plate is slidably installed inside the telescopic arm. The spring is fitted onto the outer wall of the slide rod, with one end connected to the limiting slide plate and the other end connected to the right side wall of the telescopic arm. The centrifugal force generated by the rotation of the rotary table causes the telescopic arm to extend into the telescopic groove, increasing the cleaning range and improving practicality. After the rotary table stops rotating, the spring force pushes the telescopic arm back into the storage groove for convenient use.

[0007] Preferably, the movable chip removal component includes multiple connecting blocks, a mounting plate, multiple second support rods, and a second scraper. The bottom of the rotary table has a movable groove communicating with the telescopic groove. Multiple connecting blocks are evenly installed on the bottom of the telescopic arm, and the connecting blocks are located in the movable groove. The mounting plate is installed on the bottom of the connecting blocks, and multiple second support rods are installed on the bottom of the mounting plate. The length of the bottom of the second support rods decreases from right to left, and a second scraper is installed on them, making the second scraper inclined. When the telescopic arm extends out of the telescopic groove, it drives the connecting blocks to move in the movable groove. The mounting plate and the second support rods drive the second scraper to move, so that the second scraper actively throws the chips out to the predetermined chip removal area.

[0008] Preferably, it also includes a counterweight, which is installed at the left end of the telescopic arm; the counterweight enhances the centrifugal force of the telescopic arm, ensuring smooth extension.

[0009] Preferably, it also includes a balance block, which is installed at the right end of the fixed plate; the balance block balances the eccentric force when the rotary table rotates, ensuring the stability during rotation.

[0010] Preferably, the first scraper and the second scraper are configured to be narrower at the top and wider at the bottom, and the second scraper extends out and overlaps with the first scraper. The configuration of the first scraper and the second scraper being narrower at the top and wider at the bottom can scrape off the chips on the workbench. At the same time, the second scraper extends out and overlaps with the first scraper, which can reduce cleaning dead corners and relay the chips to the predetermined chip removal area.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: when the rotary table rotates, the fixed chip removal component actively discharges the chips that have accumulated in dead corners such as the root of the rotary table. At the same time, the centrifugal force generated by the rotation of the rotary table causes the centrifugal extension component to extend, and the movable chip removal component actively throws the chips to the predetermined chip removal area. The structure is simple and does not require additional power drive. Attached Figure Description

[0013] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0014] like Figures 1 to 5As shown, the fixed plate 2 is bolted to the bottom right side of the rotary worktable 1. Multiple first support rods 3 are installed at the bottom of the fixed plate 2, with the length of the first support rods 3 decreasing from left to right. First scrapers 4 are installed on the fixed plate 2, making the first scrapers 4 inclined. A telescopic groove is provided on the bottom right side of the rotary worktable 1. A slide rod 5 is installed in the telescopic groove. A limit slide plate 6 is installed on the left end of the slide rod 5. A telescopic arm 7 is slidably installed in the telescopic groove, and the limit slide plate 6 is slidably installed inside the telescopic arm 7. A spring 8 is fitted onto the outer wall of the slide rod 5. One end of the spring 8 is connected to the limit slide plate 6, and the other end of the spring 8 is connected to the right side wall of the telescopic arm 7. The bottom of the worktable 1 is provided with a movable groove that communicates with the telescopic groove. Multiple connecting blocks 10 are evenly installed on the bottom of the telescopic arm 7. The connecting blocks 10 are located in the movable groove. The mounting plate 11 is installed on the bottom of the connecting blocks 10. Multiple second support rods 12 are installed on the bottom of the mounting plate 11. The length of the bottom of the second support rods 12 decreases from right to left. A second scraper 13 is installed on the second support rod 12, making the second scraper 13 inclined. The counterweight 9 is installed on the left end of the telescopic arm 7. The balance block 14 is installed on the right end of the fixed plate 2. The first scraper 4 and the second scraper 13 are set to be narrow at the top and wide at the bottom. After the second scraper 13 extends out, it overlaps with the first scraper 4. When the rotary worktable 1 rotates, it drives the first scraper 4 to rotate via the fixed plate 2 and the first support rod 3. The inclined first scraper 4 can guide the chips, allowing the first scraper 4 to actively discharge the chips accumulated at the root of the rotary table. The centrifugal force generated by the rotation of the rotary worktable 1 causes the telescopic arm 7 to extend into the telescopic groove, increasing the cleaning range and improving practicality. After the rotary worktable 1 stops rotating, the elastic force of the spring 8 pushes the telescopic arm 7 back into the storage groove for easy use. When the telescopic arm 7 extends into the telescopic groove, it drives the connecting block 10 to move in the movable groove, which is connected by the mounting plate. 11 and the second support rod 12 drive the second scraper 13 to move, so that the second scraper 13 actively throws the chips to the predetermined chip removal area. The counterweight block 9 enhances the centrifugal force of the telescopic arm 7 to ensure smooth extension. The balance block 14 balances the eccentric force when the rotary worktable 1 rotates to ensure stability during rotation. The first scraper 4 and the second scraper 13 are designed to be narrow at the top and wide at the bottom to scrape the chips off the worktable. At the same time, after the second scraper 13 extends, it overlaps with the first scraper 4 to reduce cleaning dead corners and relay the chips to the predetermined chip removal area.

[0015] like Figures 1 to 5As shown, this utility model discloses a five-axis machining chip removal mechanism. During operation, the rotating worktable 1 rotates, driving the first scraper 4 to rotate via the fixed plate 2 and the first support rod 3. The inclined first scraper 4 guides the chips, actively discharging the chips accumulated at the root of the turntable. Simultaneously, the centrifugal force generated by the rotation of the rotating worktable 1 causes the telescopic arm 7 to extend into the telescopic groove. When the telescopic arm 7 extends into the telescopic groove, it drives the connecting block 10 to move within the movable groove. The second scraper 13 is moved via the mounting plate 11 and the second support rod 12. The first scraper 4 and the second scraper 13 are designed with a shape that is narrower at the top and wider at the bottom to scrape off the chips on the worktable. At the same time, after the second scraper 13 extends, it overlaps with the first scraper 4, which can reduce cleaning dead corners and relay the chips to the predetermined chip removal area. After the rotating worktable 1 stops rotating, the elastic force of the spring 8 pushes the telescopic arm 7 back into the storage groove for easy use.

[0016] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
