Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to a tool changing device for a milling and boring machining center. Background Technology

[0002] The demand for tool changers in milling and boring machining centers is becoming increasingly prominent in modern manufacturing. The widespread adoption of flexible production models with multiple varieties and small batches requires frequent and rapid switching between different tools to adapt to the machining of complex parts. The construction of smart factories promotes equipment interconnection, and tool changers need to have the capabilities of status monitoring, tool life management, and predictive maintenance to seamlessly integrate into automated production lines. The increase in high-precision and high-efficiency machining tasks places higher demands on tool change speed, positioning accuracy, and the reliability of large-capacity tool magazines. Efficient tool management has also become a key link in improving overall production efficiency. Currently, the tool changing device in milling and boring machining centers requires manual cleaning of the oil stains from the replaced tool holders during the tool changing process. This is to avoid the impact of the dried oil stains on the tool holders, and storing oily tool holders is also quite troublesome. Manual cleaning is inefficient, requiring a long time and a lot of effort, which is very troublesome. In addition, the machining process may produce large metal blocks or small metal chips. Residual metal chips may affect the precision of the instrument's machining or even cause damage to the instrument. However, manual cleaning may result in accidental injury from the rotating machining tool, which is quite dangerous. Utility Model Content

[0012] Reference Figures 1-6 A tool changing device for a milling and boring machining center, comprising: A processing table 1 has a placement plate 2 fixedly connected to its upper side. A movable plate 3 is slidably mounted on the side wall of the processing table 1, and a processing blade 4 is slidably mounted on the side wall of the movable plate 3. A pneumatic rotary cylinder 5 is fixedly mounted on the side wall of the processing table 1. The pneumatic rotary cylinder 5 is a compact pneumatic actuator that simultaneously converts the energy of compressed air into limited rotational angle motion and linear telescopic motion. This is existing technology and will not be described in detail. A tool changer 6 is fixedly mounted on the output end of the pneumatic rotary cylinder 5. Both ends of the tool changer 6 have notches. The size matches the size of the processing blade 4, and it can be locked in place. A strong magnet 7 is fixedly connected to each of the two recesses. The processing blade 4 can be attracted by the strong magnet 7, so that the processing blade 4 will not fall off during the rotation process. Four support columns 8 are fixedly installed on the lower side of the processing table 1. A support plate 28 is fixedly connected to the side wall of the processing table 1. A waste bin 29 is placed on the upper side of the support plate 28. The waste bin 29 can collect the metal shavings generated during processing. An oil removal structure is installed on the processing table 1. A cleaning structure is also installed on the processing table 1.

[0013] The degreasing structure includes a spur gear 9 fixedly sleeved on the outside of the output end of the pneumatic rotary cylinder 5. Spur gear 9 is located on the rod at the top of the pneumatic rotary cylinder 5. When the pneumatic rotary cylinder 5 extends its output end, spur gear 9 will not affect the pneumatic rotary cylinder 5. A rotating shaft 10 is rotatably connected to the side wall of the processing table 1. A spur gear 11 is fixedly sleeved on the outside of the rotating shaft 10. The distance the pneumatic rotary cylinder 5 extends forward through its output end allows spur gear 9 and spur gear 11 to mesh. Because the pneumatic rotary cylinder 5 is a precision component and rotates at a constant angle of 90 degrees, spur gear 9 can mesh with spur gear 11 after each movement. Furthermore, a rubber ring is fitted at the rotating connection of the rotating shaft 10 to prevent the rotating shaft 10 from shifting when no force is applied. When the machine rotates, a rotating shaft 12 is rotatably connected to the side wall of the machining table 1. The rotating shaft 12 is rotatably connected to the rotating shaft 10 through a pulley assembly 13. The pulley assembly 13 consists of two identical rotating wheels and a belt. Three rotating rods 14 are rotatably connected to the upper side of the machining table 1. One of the rotating rods 14 and the outer side of the rotating shaft 12 are fixedly fitted with bevel gears 15. This rotating rod 14 is the middle rotating rod 14, and the two bevel gears 15 mesh with each other. The rotating rod 14 is connected to the other two rotating rods 14 through a pulley assembly 2 16. The pulley assembly 2 16 also consists of two identical rotating wheels and a belt. A cleaning disc 17 is fixedly connected to the upper end of each of the three rotating rods 14. The cleaning disc 17 can clean the oil stains on the handle of the machining tool 4.

[0014] The cleaning structure includes a rotating shaft 2 18 rotatably connected to the side wall of the processing table 1. A rubber ring is fitted at the rotatable connection of the rotating shaft 2 18 to prevent it from rotating under no force. A spur gear 3 19 is fixedly fitted to the outside of the rotating shaft 2 18. The spur gear 3 19 is exactly the same size and number of teeth as the spur gear 2 11, ensuring that after the spur gear 1 9 drives the spur gear 2 11 or the spur gear 3 19 to rotate, it can still perfectly mesh with the other gear during subsequent movement, preventing tooth jamming. A rotating shaft 2 30 is rotatably connected to the side wall of the processing table 1. The rotating shaft 2 30 is connected to the rotating shaft 2 18 via a pulley assembly 3 20, which consists of two identical pulleys and a belt. A rotating shaft 3 21 is rotatably connected to the side wall of the processing table 1. The rotating shaft 30 is connected to the rotating shaft 3 21 via a pulley assembly 4 22, which consists of a large pulley fixedly fitted to the outside of the rotating shaft 2 30 and a small pulley fixed to the outside of the rotating shaft 3 21. The system consists of a wheel and a belt, allowing the large rotating wheel to drive the small rotating wheel to rotate multiple times when rotating slightly. This is existing technology and will not be elaborated further. A reciprocating screw 23 is rotatably connected to the side wall of the processing table 1. A rubber ring is fitted at the rotatable connection of the reciprocating screw 23 to prevent it from rotating on its own. Both the reciprocating screw 23 and the outer side of the rotating shaft 21 are fixedly fitted with bevel gears 24, and the two bevel gears 24 mesh with each other. A cleaning plate 25 is slidably connected to the side wall of the processing table 1. A reciprocating block 26 is rotatably connected to the side wall of the cleaning plate 25. The reciprocating block 26 can slide along the groove on the outer side of the reciprocating screw 23. Multiple sets of cleaning brushes are fixedly connected to the lower side of the cleaning plate 25. Multiple small vacuum cleaners 27 are installed on the upper side of the cleaning plate 25. Each small vacuum cleaner 27 consists of a vacuum pump and a collection box, which can suck up small metal debris, solving the problem that the cleaning brushes cannot clean up small metal debris. Large metal debris can be cleaned into the waste bin for collection.

[0015] In this invention, the operator first inputs a command to the pneumatic rotary cylinder 5 via a computer, causing the pneumatic rotary cylinder 5 to rotate the tool changer 6 so that the notch of the tool changer 6 engages with the processing tool 4. During this rotation, the output end of the pneumatic rotary cylinder 5 drives the spur gear 19 to rotate via the spur gear 19. The spur gear 19 drives the rotating shaft 30 to rotate via the rotating shaft 28 and the pulley assembly 30. The rotating shaft 30 drives the rotating shaft 21 to rotate via the pulley assembly 42. The rotating shaft 21 drives the reciprocating screw 23 to rotate via two bevel gears 24. The reciprocating screw 23, through the reciprocating block 26, enables the cleaning plate 25 to reciprocate. The number of rotations of the reciprocating screw 23 is just enough to make the cleaning plate 25 complete one full reciprocating motion. The cleaning brush and the small vacuum cleaner 27 clean up the debris generated during processing. The debris is cleaned to facilitate the next processing. At this time, the pneumatic rotary cylinder 5 disengages the processing tool 4 from the moving plate 3. The spur gear 9 moves with the output end of the pneumatic rotary cylinder 5, allowing the spur gear 9 to mesh with the spur gear 11. The pneumatic rotary cylinder 5 rotates again, causing the spur gear 9 to drive the spur gear 11 to rotate. This, in turn, drives the rotating shaft 12 to rotate through the rotating shaft 10 and the pulley assembly 13. The rotating shaft 12 drives one of the rotating rods 14 to rotate through two bevel gears 15. The rotating rod 14 drives the rotating rods 14 on both sides to rotate through the two pulley assemblies 16. This, in turn, drives the cleaning disc 17 to rotate. The cleaning disc 17 cleans the handle of the processing tool 4. The cleaning disc 17 can be replaced to avoid the decrease in cleaning effect caused by repeated use.
