Description

Technical Field

[0001] The invention relates to the technical field of machine tools, in particular to a machine tool for producing copper inserts. Background Art

[0002] In the production of copper inserts, the following machine tools are usually used: CNC lathe: can accurately turn the outer circle, inner hole, end face and other shapes of copper inserts to achieve high-precision processing; milling machine: used to process various grooves, steps and other features on copper inserts. Drilling machine: performs drilling operations to meet the needs of mounting holes on copper inserts; tapping machine: used to process threads on copper inserts; grinding machine: can further improve the surface finish and dimensional accuracy of copper inserts.

[0003] When the machine tool processes the copper inlay, the milling cutter on the machine tool needs to contact the copper inlay. When the milling cutter contacts the copper inlay, the copper inlay rotates, the copper inlay and the milling cutter rub against each other, and the milling cutter engraves the copper inlay. During the copper inlay processing, the milling cutter needs to move frequently to ensure that the milling cutter processes the copper inlay. After the milling cutter moves, the milling cutter needs to stop. When the milling cutter stops, since the mounting seat of the milling cutter is heavy, when the mounting seat on which the milling cutter is installed stops, it is easy to move slightly due to inertia, and the stopping position of the milling cutter deviates, so that the size or shape of the processed workpiece does not meet the requirements, resulting in a decrease in the production quality of the workpiece.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The output shaft of the servo motor drives the gear to move. Through the meshing of the driving gear and the rack, the structure composed of the lower assembly plate and the upper assembly plate is driven to move on the inner assembly plate, thereby driving the structure on the second movable cover to move back and forth. When the lower assembly plate and the upper assembly plate move on the inner assembly plate, the rectangular mounting seat and the U-shaped connecting frame will be driven to move in the positioning frame. The rectangular mounting seat and the U-shaped connecting frame move outside the rectangular insertion strip, and the buffer gear connected to the rectangular mounting seat is meshed with the tooth groove. When the rectangular mounting seat and the U-shaped connecting frame move outside the rectangular insertion strip, the buffer gear is also rotated through the meshing with the rectangular insertion strip. The rotation on the buffer gear The shaft and the annular spring piece rotate in the assembly ring. After the rectangular mounting seat and the U-shaped connecting frame stop moving, the rotating shaft and the assembly ring also stop in the assembly ring. During the rotation of the annular spring piece, the annular spring piece will be deformed and the pressure generated by the contact with the assembly ring is small. When stopping, the annular spring piece returns to its original state and continues to contact and rub the assembly ring, generating reverse power to block the continued rotation of the rotating shaft and the annular spring piece, thereby reducing the force generated by the inertia of the rectangular mounting seat and the U-shaped connecting frame, enabling the instrument to stop at the target position faster and more accurately, reducing the position deviation caused by inertia, shortening the transition time from movement to stillness of the instrument, and making the operation process more compact and efficient.

[0015] 2. According to the cutting height requirements, the height of the structure composed of the top mounting seat, the first movable cover and the second movable cover is adjusted. When frequent adjustments are required, the locking nut is turned to separate the locking nut and the threaded rod, and the top mounting seat, the first movable cover and the second movable cover are driven to rise and fall by the output shaft of the electric push rod to adjust the height of the structure composed of the top mounting seat, the first movable cover and the second movable cover. When the height of the structure composed of the top mounting seat, the first movable cover and the second movable cover does not need to be adjusted frequently, the locking nut is threadedly installed on the threaded rod, and the height of the structure composed of the circular fixed shaft and the threaded rod is changed by rotating the locking nut. The height of the structure composed of the top mounting seat, the first movable cover and the second movable cover is adjusted to ensure that the structure on the second movable cover can work better, adapt to different cutting heights, and can better match and coordinate with other surrounding equipment or facilities.

[0016] 3. Fix the scale on the fixing buckle by turning the locking bolt, and observe the distance between the top mounting seat and the assembly seat according to the scale on the scale to ensure the accuracy of the distance adjustment between the top mounting seat and the assembly seat and improve the convenience of adjustment.

[0017] 4. When the lateral position of the structure on the second movable cover is adjusted, the second movable cover is pushed to move by the oil cylinder on one side of the top mounting seat. When the second movable cover moves, the second limit rod in the second movable cover moves in the grooves on both sides of the first movable cover, and the second limit end strips in the grooves on both sides of the first movable cover limit the movement of the second limit rod to ensure that the second movable cover will not fall off the first movable cover while moving. At the same time, the resistance generated by the pressure exerted by the movement of the second movable cover on the first movable cover will also push the first movable cover to move on the top mounting seat. When the first movable cover moves on the top mounting seat, the first limit end strip limits the first limit rod to ensure that the first movable cover will not fall off the top mounting seat. The resistance and shaking generated by the movement of the second movable cover on the first movable cover and the movement of the first movable cover on the top mounting seat are reduced.

The rectangular insert 12 is arranged on the central axis of the positioning frame 11, and the rectangular insert 12 is clearance-matched with the rectangular mounting seat 8 and the U-shaped connecting frame 9. When the rectangular insert 12 moves in the rectangular mounting seat 8 and the U-shaped connecting frame 9, the rectangular insert 12 will not generate large friction with the rectangular mounting seat 8 and the U-shaped connecting frame 9, affecting the sliding stability of the rectangular mounting seat 8 and the U-shaped connecting frame 9.

[0035] The rectangular insert 12 is movably inserted in the semi-enclosed structure composed of the rectangular mounting seat 8 and the U-shaped connecting frame 9. A tooth groove 13 is provided at the bottom of the rectangular insert 12. A rotating shaft 14 is rotatably connected to the rectangular mounting seat 8. A buffer gear 15 is fixedly installed outside the rotating shaft 14. The tooth grooves on the tooth grooves 13 correspond to the teeth of the buffer gear 15 to ensure the meshing effect of the buffer gear 15 and the tooth grooves 13.

After the rectangular mounting seat 8 and the U-shaped connecting frame 9 stop moving, the rotating shaft 14 and the assembly ring 17 also stop in the assembly ring 17. During the rotation of the annular spring piece 16, the annular spring piece 16 will be deformed and the pressure generated by the contact with the assembly ring 17 is small. When stopping, the annular spring piece 16 returns to its original state and continues to contact and rub with the assembly ring 17, generating reverse power to block the continued rotation of the rotating shaft 14 and the annular spring piece 16, thereby reducing the force generated by the moving inertia of the rectangular mounting seat 8 and the U-shaped connecting frame 9.

[0036] A fixing frame 18 is provided in the machine tool body 1, and a servo motor 19 is fixedly mounted on the fixing frame 18. A driving gear 20 is fixedly mounted on the output shaft of the servo motor 19. The driving gear 20 is meshed with a rack 21 provided at the bottom of the lower assembly plate 5. The servo motor 19 is supported by the fixing frame 18 to assist the installation of the servo motor 19.

The dust collecting groove 22 is a trapezoidal groove for guiding, and the dust guide groove 23 is a guiding groove to assist the movement of copper chips.

[0038] A fixed rectangular frame 24 is fixedly installed in the dust collecting trough 22, and a movable rectangular frame 25 is placed above the fixed rectangular frame 24. The positions of the fixed rectangular frame 24 and the movable rectangular frame 25 correspond, and the movable rectangular frame 25 is located above the fixed rectangular frame 24. A rotating rod 26 is movably inserted on the fixed rectangular frame 24 and the movable rectangular frame 25, and a semicircular groove corresponding to the rotating rod 26 is provided on the fixed rectangular frame 24 and the movable rectangular frame 25. Through the cooperation of the semicircular grooves on the fixed rectangular frame 24 and the movable rectangular frame 25, the rotating rod 26 is movably engaged with the fixed rectangular frame 24 and the movable rectangular frame 25.

[0040] refer to Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 A telescopic rod 29 is provided on the top of the assembly plate 6, and a top mounting seat 30 is fixedly installed on the top of the telescopic rod 29. An assembly seat 28 is also provided on the top of the upper assembly plate 6, and an electric push rod 2801 is also provided on the top of the assembly seat 28. The piston rod end of the electric push rod 2801 is supported at the corresponding position of the bottom of the top mounting seat 30. The piston rod of the electric push rod 2801 applies pressure to the top mounting seat 30, pushing the top mounting seat 30 to rise and fall, which is suitable for frequent lifting and lowering operations of the top mounting seat 30.

[0041] A circular fixed shaft 31 is provided at the top of the assembly seat 28, and a locking nut 32 is rotatably connected to the circular fixed shaft 31. The locking nut 32 is internally threadedly connected to a threaded rod 33, and the threaded rod 33 is fixedly installed at the bottom center position of the top mounting seat 30. The locking nut 32 rotates on the circular fixed shaft 31. By rotating the locking nut 32 on the threaded rod 33, the distance between the assembly seat 28 and the top mounting seat 30 is changed, thereby adjusting the height of the components on the second movable cover 38.

[0042] The top mounting seat 30 is slidably connected to the outside of a first movable cover 37, and the first movable cover 37 is slidably connected to the outside of a second movable cover 38. First limiting rods 39 are arranged in the grooves on both sides of the top mounting seat 30, and the inner wall of the first movable cover 37 is provided with a first limiting end strip 40 corresponding to the first limiting rod 39. The first limiting end strip 40 limits the end of the first limiting rod 39 to prevent the first movable cover 37 from falling off the top mounting seat 30. Second limiting rods 41 corresponding to the grooves on both sides of the first movable cover 37 are arranged on the inner wall of the second movable cover 38, and second limiting end strips 42 corresponding to the ends of the second limiting rod 41 are arranged in the grooves on both sides of the first movable cover 37. The second limiting end strip 42 limits the end of the second limiting rod 41 to prevent the second movable cover 38 from falling off the first movable cover 37.

[0043] Working principle: The first step: according to the cutting height requirements, the height of the structure composed of the top mounting seat 30, the first movable cover 37 and the second movable cover 38 is adjusted. When frequent adjustment is required, the locking nut 32 is turned to separate the locking nut 32 and the threaded rod 33, and the top mounting seat 30, the first movable cover 37 and the second movable cover 38 are driven to rise and fall by the output shaft of the electric push rod 2801 to adjust the height of the structure composed of the top mounting seat 30, the first movable cover 37 and the second movable cover 38. When the height of the structure composed of the top mounting seat 30, the first movable cover 37 and the second movable cover 38 is not required to be frequently adjusted, the locking nut 32 is threadedly installed on the threaded rod 33, and the height of the structure composed of the circular fixed shaft 31 and the threaded rod 33 is changed by rotating the locking nut 32, and the height of the structure composed of the top mounting seat 30, the first movable cover 37 and the second movable cover 38 is adjusted to ensure that the structure on the second movable cover 38 can work better.

[0044] Step 2: Fix the scale 35 on the fixing buckle 34 by rotating the locking bolt 36, and observe the distance between the top mounting seat 30 and the assembly seat 28 according to the scale on the scale 35 to ensure the accuracy of the distance adjustment between the top mounting seat 30 and the assembly seat 28 and improve the convenience of adjustment.

[0045] The third step: when the lateral position of the structure on the second movable cover 38 is adjusted, the second movable cover 38 is pushed to move by the oil cylinder on one side of the top mounting seat 30. When the second movable cover 38 moves, the second limiting rod 41 in the second movable cover 38 moves in the grooves on both sides of the first movable cover 37, and the second limiting end strips 42 in the grooves on both sides of the first movable cover 37 limit the movement of the second limiting rod 41 to ensure that the second movable cover 38 does not fall off the first movable cover 37 while moving. At the same time, the resistance generated by the pressure exerted by the movement of the second movable cover 38 on the first movable cover 37 will also push the first movable cover 37 to move on the top mounting seat 30. When the first movable cover 37 moves on the top mounting seat 30, the first limiting end strip 40 limits the first limiting rod 39 to ensure that the first movable cover 37 does not fall off the top mounting seat 30. By moving the second movable cover 38 on the first movable cover 37 and the first movable cover 37 on the top mounting seat 30, the resistance and shaking generated by the movement of the second movable cover 38 are reduced.

[0046] Step 4: The output shaft of the servo motor 19 drives the gear 20 to move. The gear 20 and the rack 21 are meshed to drive the structure composed of the lower assembly plate 5 and the upper assembly plate 6 to move on the inner assembly plate 4, thereby driving the structure on the second movable cover 38 to move back and forth. When the lower assembly plate 5 and the upper assembly plate 6 move on the inner assembly plate 4, the rectangular mounting seat 8 and the U-shaped connecting frame 9 are driven to move in the positioning frame 11, and the rectangular mounting seat 8 and the U-shaped connecting frame 9 are moved outside the rectangular insert 12. The buffer gear 15 and the tooth groove 13 are meshed by the rotation connection on the rectangular mounting seat 8, and the rectangular mounting seat 8 and the U-shaped connecting frame 9 are moved outside the rectangular insert 12. When the buffer gear 15 is engaged with the rectangular insert 12, it also rotates. The rotating shaft 14 and the annular spring piece 16 on the buffer gear 15 rotate in the assembly ring 17. After the rectangular mounting seat 8 and the U-shaped connecting frame 9 stop moving, the rotating shaft 14 and the assembly ring 17 also stop in the assembly ring 17. During the rotation of the annular spring piece 16, the annular spring piece 16 will be deformed and the pressure generated by the contact with the assembly ring 17 is small. When stopping, the annular spring piece 16 returns to its original state and continues to contact and rub with the assembly ring 17, generating a reverse power to block the continued rotation of the rotating shaft 14 and the annular spring piece 16, thereby reducing the force generated by the moving inertia of the rectangular mounting seat 8 and the U-shaped connecting frame 9.
