Description

Technical Field

[0001] This utility model relates to the field of waste material recycling devices, and in particular to a waste material recycling device for automated milling of pin shafts. Background Technology

[0002] Pins are a type of standardized fastener that can provide both static fixation and relative movement with the connected parts. They are primarily used at the hinge joints of two parts to form a hinge connection. Pins are typically locked with cotter pins, ensuring reliable operation and easy disassembly. Automated milling of pins generates excess material, which can be reused.

[0003] Currently, when cleaning and recycling the excess material generated during the existing pin milling process, manual cleaning is required. This manual cleaning and recycling of scattered excess material is not only time-consuming and labor-intensive, but also results in incomplete cleaning and recycling, leaving a small amount of excess material in the corners of the worktable, thus leading to poor cleaning results. Utility Model Content

[0004] To overcome the problems of time-consuming, labor-intensive, and incomplete recycling of existing manual cleaning and recycling methods.

[0005] The technical solution of this utility model is as follows: a waste material recycling device for automated milling of pin shafts, including a processing table and a protective cylinder with a threaded connection inside the processing table. The bottom of the protective cylinder has an inner groove, and a receiving frame is welded inside the inner groove. A servo motor is fixedly connected to the outside of the receiving frame. The output shaft of the servo motor passes through the side wall of the receiving frame and is welded with a reciprocating screw. A screw nut is connected to the outer wall of the reciprocating screw. The screw nut is fixedly connected inside the scraper. The bottom of the scraper abuts against the bottom of the inner side of the receiving frame. A discharge port is opened at the bottom of the inner side of the receiving frame. A receiving trough is set below the discharge port and is placed on the top of the middle horizontal plate of the processing table.

[0006] Preferably, by operating the servo motor, the servo motor drives the reciprocating screw to rotate through the output shaft. When the reciprocating screw rotates, it can drive the scraper where the screw nut is located to make horizontal reciprocating motion. The scraper abuts against the bottom of the inner side of the receiving frame, so that the scraper can scrape the falling residual material to the discharge port of the receiving frame and collect it through the collection trough below the discharge port. Therefore, manual cleaning and recycling are not required. The operation is very simple, time-saving and labor-saving, thereby further improving the efficiency of residual material recycling.

[0007] Preferably, a conical clamp is fixedly connected to the inner side of the processing table. The pin body is clamped inside the conical clamp, and a clamping and fixing component is installed inside the conical clamp to fix the pin body.

[0008] Preferably, an electric cylinder is fixedly connected to the inner side of the processing table away from the conical clamp, and a telescopic shaft is slidably connected inside the electric cylinder, with one end of the telescopic shaft welded to the side of the motor mounting plate.

[0009] Preferably, the motor mounting plate has two sets of guide rods slidably connected inside. One end of each set of guide rods is fixedly connected to the side of the processing table near the electric cylinder, and the other end of each set of guide rods is welded with a stop block.

[0010] Preferably, a high-speed motor is fixedly connected to the side of the motor mounting plate away from the telescopic shaft. The output shaft of the high-speed motor is welded to a rotating shaft. One end of the rotating shaft is fixedly connected to a tool mounting seat. A milling tool is mounted on the side of the tool mounting seat.

[0011] Preferably, two sets of fixing blocks are welded to the outside of the protective cylinder. Each set of fixing blocks has a threaded hole inside, and a bolt is threaded into the threaded hole. The bolt is connected to a threaded hole on the inside of the processing table.

[0012] Preferably, wedge-shaped guide blocks are fixedly connected to both sides of the scraper, and wedge-shaped guide grooves are opened on both sides of the receiving frame. The two sets of wedge-shaped guide blocks slide within the two sets of wedge-shaped guide grooves. The wedge-shaped guide grooves have slopes, which can allow the falling residual material to be discharged.

[0013] The beneficial effects of this utility model are:

[0014] 1. The waste material recovery device for the automated milling of the pin shaft uses a servo motor to drive a reciprocating screw through the output shaft. When the reciprocating screw rotates, it drives the scraper where the screw nut is located to make a horizontal reciprocating motion. The scraper abuts against the bottom of the inner side of the receiving frame, so that the scraper can scrape the falling waste material to the discharge port of the receiving frame and recover it through the collection trough below the discharge port. This eliminates the need for manual cleaning and recovery, making the operation very simple, time-saving and labor-saving, and further improving the efficiency of waste material recovery.

[0015] 2. The waste material recovery device for the automated milling of the pin shaft, by setting up an automatic milling component, operates an electric cylinder, which drives a motor mounting plate to extend and retract via a telescopic shaft. A high-speed motor is mounted on the side of the motor mounting plate, and the high-speed motor is welded to a rotating shaft via an output shaft. One end of the rotating shaft is fixedly connected to a tool mounting seat, and a milling cutter is mounted on the side of the tool mounting seat. Thus, when the telescopic shaft extends outward, the milling cutter can extend to the pin shaft body held and fixed by the conical chuck. Then, the high-speed motor is operated, causing the high-speed motor to drive the tool mounting seat on the rotating shaft to rotate, thereby enabling the tool mounting seat to drive the milling cutter to rotate, thus achieving the effect of automatically milling the pin shaft body.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a waste material recovery device for automated milling of pin shafts, including a processing table 1 and a protective cylinder 13 threaded to the inner side of the processing table 1. The bottom of the protective cylinder 13 has an inner groove, and a receiving frame 16 is welded inside the inner groove. A servo motor 17 is fixedly connected to the outer side of the receiving frame 16. The output shaft of the servo motor 17 passes through the side wall of the receiving frame 16 and is welded to a reciprocating screw 18. A screw nut 19 is connected to the outer wall of the reciprocating screw 18 and is fixedly connected inside a scraper 20. The bottom of the scraper 20 abuts against the bottom of the inner side of the receiving frame 16. A discharge port 23 is provided at the bottom of the inner side of the receiving frame 16, and a receiving trough 24 is provided below the discharge port 23. The receiving trough 24 is placed on top of the middle horizontal plate of the processing table 1. The protective cylinder 13 serves as a protective measure, preventing the residual material generated by the pin body 3 during milling from splashing to the outside, which would cause inconvenience in cleaning and recycling. At the same time, it avoids the injury to workers caused by the splashing residual material. The receiving frame 16 is used to receive the residual material generated during processing and can collect it together. The servo motor 17 drives the reciprocating screw 18 to rotate through the output shaft. When the reciprocating screw 18 rotates, it can drive the scraper 20 where the screw nut 19 is located to move horizontally back and forth, so that the scraper 20 can scrape out the residual material at the bottom of the inner side of the receiving frame 16. The discharge port 23 is used to discharge the scraped residual material, and the receiving trough 24 is used to collect the residual material.

[0024] Please see Figure 2 In this embodiment, a conical clamp 2 is fixedly connected to the inner side of the processing table 1. The conical clamp 2 holds a pin body 3 inside, and a clamping and fixing component is installed inside the conical clamp 2 to fix the pin body 3. An electric cylinder 4 is fixedly connected to the inner side of the processing table 1 away from the conical clamp 2. A telescopic shaft 5 is slidably connected inside the electric cylinder 4, and one end of the telescopic shaft 5 is welded to the side of the motor mounting plate 6. Two sets of guide rods 7 are slidably connected inside the motor mounting plate 6. One end of each set of guide rods 7 is fixedly connected to the side of the processing table 1 near the electric cylinder 4, and the other end of each set of guide rods 7 is welded to a stop block 8. A high-speed motor 9 is fixedly connected to the side of the motor mounting plate 6 away from the telescopic shaft 5, and the output shaft of the high-speed motor 9 is welded to the side of the motor mounting plate 6 away from the telescopic shaft 5. A rotating shaft 10 is provided, with a tool mounting base 11 fixedly connected to one end. A milling tool 12 is mounted on the side of the tool mounting base 11. A clamping component is installed inside the tapered clamp 2, which can clamp and fix the pin body 3. An electric cylinder 4 can drive a motor mounting plate 6 to perform horizontal telescopic movement via a telescopic shaft 5. The motor mounting plate 6 is used to mount a high-speed motor 9. A guide rod 7 is used to guide the movement of the motor mounting plate 6. A stop block 8 is used to prevent the guide rod 7 from disengaging from the motor mounting plate 6. The high-speed motor 9 can drive the rotating shaft 10 to rotate through the output shaft, so that the rotating shaft 10 can drive the milling tool 12 on the tool mounting base 11 to rotate, thereby enabling the milling tool 12 to perform milling processing on the pin body 3.

[0025] Please see Figure 1 , Figure 5 In this embodiment, two sets of fixing blocks 14 are welded to the outside of the protective cylinder 13. Each set of fixing blocks 14 has a threaded hole inside, and a bolt 15 is threadedly connected inside the threaded hole. The bolt 15 is connected to the threaded hole on the inside of the processing table 1. The fixing block 14 has a threaded hole inside, which can be threadedly connected to the bolt 15. In this way, the protective cylinder 13 can be installed on the inside of the processing table 1, which makes it convenient to disassemble the entire device where the protective cylinder 13 is located.

[0026] Please see Figure 3 , Figure 4 In this embodiment, wedge-shaped guide blocks 21 are fixedly connected to both sides of the scraper 20, and wedge-shaped guide grooves 22 are opened on both sides of the receiving frame 16. The two sets of wedge-shaped guide blocks 21 slide within the two sets of wedge-shaped guide grooves 22. The wedge-shaped guide grooves 22 have slopes to allow the falling residual material to be discharged. The two sets of wedge-shaped guide blocks 21 are used to guide the movement of the scraper 20 and prevent the scraper 20 from deviating when it moves. The two sets of wedge-shaped guide grooves 22 allow the two sets of wedge-shaped guide blocks 21 to slide within them.

[0027] During operation, the servo motor 17 is operated to drive the reciprocating screw 18 to rotate via the output shaft. When the reciprocating screw 18 rotates, it drives the scraper 20, where the screw nut 19 is located, to perform horizontal reciprocating motion. The scraper 20 abuts against the bottom of the inner side of the receiving frame 16, so that the scraper 20 can scrape the falling residual material to the discharge port 23 opened in the receiving frame 16 and collect it through the collection trough 24 below the discharge port 23. This eliminates the need for manual cleaning and recycling, making the operation very simple, time-saving, and labor-saving, thereby further improving the efficiency of residual material recycling.

[0028] Through the above steps, by operating the servo motor 17, the scraper 20 can scrape the remaining material in the receiving frame 16 to the discharge port 23, and then recycle it through the receiving trough 24 below the discharge port 23, so as to solve the problem that the existing manual cleaning and recycling of remaining material is time-consuming, labor-intensive and not thorough enough.
