A machine tool for the production of copper inserts

Abstract

The present invention relates to the technical field of machine tools, and specifically relates to a machine tool for the production of copper inserts, including a machine tool body and a movable door slidably connected to the machine tool body. Assembly frames are provided on both sides of the inner wall of the machine tool body. An inner insertion assembly plate is arranged between the two assembly frames. A lower assembly plate and an upper assembly plate are movably sleeved outside the inner insertion assembly plate. The lower assembly plate and the upper assembly plate are fixedly connected by a first connecting bolt. During the rotation of the annular elastic piece, the annular elastic piece will deform and the pressure generated by contacting the assembly ring is small. When it stops, the annular elastic piece returns to its original state and continues to contact and rub with the assembly ring, generating a reverse driving force to block the continuous rotation of the rotating shaft and the annular elastic piece, thereby reducing the force generated by the moving 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 of the instrument from motion to rest, and making the operation process more compact and efficient.

Description

Technical Field

[0001] The present invention relates to the technical field of machine tools, and specifically to a machine tool for the production of copper inserts. Background Technique

[0002] In the production of copper inserts, the following types of machine tools are usually used: CNC lathes: capable of precisely turning the outer circle, inner hole, end face, etc. of copper inserts to achieve high-precision machining; milling machines: used to machine various grooves, steps, etc. on copper inserts. Drilling machines: perform drilling operations to meet the requirements of mounting holes, etc. on copper inserts; tapping machines: used to machine threads on copper inserts; grinding machines: can further improve the surface finish and dimensional accuracy of copper inserts.

[0003] When machining copper inserts with a machine tool, it is necessary to contact the milling cutter on the machine tool with the copper insert. When the milling cutter contacts the copper insert, the copper insert rotates, and friction occurs between the copper insert and the milling cutter. The milling cutter engraves the copper insert. During the process of machining the copper insert, the milling cutter needs to move frequently to ensure the machining of the copper insert by the milling cutter. After the milling cutter moves, it is necessary to stop the milling cutter. When the milling cutter stops, due to the heavy mounting seat of the milling cutter, when the mounting seat for installing the milling cutter stops, it is prone to slightly move due to inertia, and the stop position of the milling cutter deviates, resulting in the size or shape of the machined workpiece not meeting the requirements, and the production quality of the workpiece deteriorates.

[0012] Preferably, a circular fixed shaft is arranged on the top of the assembly seat, a locking nut is rotatably connected to the circular fixed shaft, a threaded rod is threadedly connected inside the locking nut, and the threaded rod is fixedly installed at the center position of the bottom of the top mounting seat.

[0013] Preferably, a first movable cover is slidably connected to the outside of the top mounting seat, a second movable cover is slidably connected to the outside of the first movable cover, first limiting rods are arranged in the grooves on both sides of the top mounting seat, first limiting end strips corresponding to the first limiting rods are arranged on the inner wall of the first movable cover, second limiting rods corresponding to the grooves on both sides of the first movable cover are arranged on the inner wall of the second movable cover, and second limiting end strips corresponding to the ends of the second limiting rods are arranged in the grooves on both sides of the first movable cover.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The output shaft of the servo motor drives the driving 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 interpolation 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 interpolation assembly plate, they will drive the rectangular mounting seat and the U-shaped connecting frame to move within the positioning frame. The rectangular mounting seat and the U-shaped connecting frame move outside the rectangular insert. Through the meshing of the buffer gear rotatably connected to the rectangular mounting seat and the tooth groove, when the rectangular mounting seat and the U-shaped connecting frame move outside the rectangular insert, the buffer gear also rotates through meshing with the rectangular insert. The rotating shaft on the buffer gear and the annular elastic piece rotate within 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 within the assembly ring. During the rotation of the annular elastic piece, the annular elastic piece will deform and the pressure generated by contacting the assembly ring is small. When it stops, the annular elastic piece returns to its original shape and continues to contact and rub against the assembly ring, generating a reverse driving force to block the continued rotation of the rotating shaft and the annular elastic piece, thereby reducing the force generated by the moving 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 of the instrument from motion to rest, and making the operation process more compact and efficient.

[0016] 2. According to the height requirement of cutting, adjust the height of the structure composed of the top mounting seat, the first movable cover, and the second movable cover. When frequent adjustment is required, turn the lock nut to separate the lock nut from the threaded rod, and drive the top mounting seat, the first movable cover, and the second movable cover to lift and lower through 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 it is not necessary to frequently adjust the height of the structure composed of the top mounting seat, the first movable cover, and the second movable cover, thread the lock nut onto the threaded rod, and adjust the height of the structure composed of the circular fixed shaft and the threaded rod by rotating the lock nut to adjust the height of the structure composed of the top mounting seat, the first movable cover, and the second movable cover, ensuring that the structure on the second movable cover can work better, adapt to different cutting heights, and can be better matched and coordinated with other surrounding equipment or facilities.

[0017] 3. Fix the scale on the fixed buckle by rotating the lock 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.

[0018] 4. When adjusting the lateral position of the structure on the second movable cover, 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 limiting rod in the second movable cover moves in the grooves on both sides of the first movable cover, and the second limiting end strips in the grooves on both sides of the first movable cover limit the movement of the second limiting 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 of the second movable cover on the first movable cover during the movement of the second 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 limiting end strip limits the first limiting rod to ensure that the first movable cover will not fall off the top mounting seat. 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, the resistance and shaking generated by the movement of the second movable cover are reduced.

Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 14, the present invention provides a technical solution: a machine tool for producing copper inserts, including a machine tool body 1 and a movable door 2 slidably connected to the machine tool body 1. The movable door 2 can slide on the machine tool body 1 to realize the display and closing of the working space inside the machine tool body 1. Assembly frames 3 are arranged on both sides of the inner wall of the machine tool body 1. An inner insertion assembly plate 4 is arranged between the two assembly frames 3. The assembly frames 3 are used for the installation and erection of the inner insertion assembly plate 4. A lower assembly plate 5 and an upper assembly plate 6 are movably sleeved outside the inner insertion assembly plate 4. Both the lower assembly plate 5 and the upper assembly plate 6 are U-shaped structures, and the lower assembly plate 5 and the upper assembly plate 6 are symmetrically arranged up and down. The lower assembly plate 5 and the upper assembly plate 6 are connected and fixed by a first connecting bolt 7. The lower assembly plate 5 and the upper assembly plate 6 are fixedly connected by the first connecting bolt 7. A rectangular mounting seat 8 is fixedly installed at the center position of the top of the lower assembly plate 5. A U-shaped connecting frame 9 is fixedly installed at the top of the rectangular mounting seat 8 through a second connecting bolt 10. The rectangular mounting seat 8 and the U-shaped connecting frame 9 form a U-shaped structure to assist the installation of the rectangular insert 12 in the rectangular mounting seat 8 and the U-shaped connecting frame 9. A positioning frame 11 is horizontally and fixedly installed inside the inner insertion assembly plate 4. The thickness of the positioning frame 11 is less than the thickness of the inner insertion assembly plate 4 to ensure that the positioning frame 11 does not affect the normal use of the inner insertion assembly plate 4. A rectangular insert 12 is fixedly installed inside the positioning frame 11. The rectangular insert 12 is arranged on the central axis of the positioning frame 11, and the rectangular insert 12 has a clearance fit 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.

[0036] The rectangular insert 12 is movably inserted into the semi-enclosed structure formed by 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 groove 13 correspond to the teeth of the buffer gear 15 to ensure the meshing effect between the buffer gear 15 and the tooth groove 13. The buffer gear 15 meshes with the tooth groove 13. An annular elastic sheet 16 is fixedly installed at the end of the rotating shaft 14. The annular elastic sheet 16 is an elastic sheet with deformation ability and is composed of multiple intersecting elastic sheets. During the process of the rotating shaft 14 driving the annular elastic sheet 16 to rotate in the assembly ring 17, the annular elastic sheet 16 contacts the assembly ring 17. When the annular elastic sheet 16 stops rotating, the frictional force generated between the annular elastic sheet 16 and the assembly ring 17 will block the continued movement of the rotating shaft 14, thereby reducing the movement amplitude of the rectangular insert 12 due to inertia. An assembly ring 17 is fixedly installed on the rectangular mounting seat 8 outside the rotating shaft 14 and the annular elastic sheet 16, and the assembly ring 17 is rotatably connected to the annular elastic sheet 16. The assembly ring 17 limits the rotation of the rotating shaft 14 and the annular elastic sheet 16 to ensure the rotation stability of the annular elastic sheet 16 and the rotating shaft 14. The rectangular mounting seat 8 and the U-shaped connecting frame 9 move outside the rectangular insert 12. Through the meshing of the buffer gear 15 rotatably connected to the rectangular mounting seat 8 and the tooth groove 13, when the rectangular mounting seat 8 and the U-shaped connecting frame 9 move outside the rectangular insert 12, the buffer gear 15 also rotates through meshing with the rectangular insert 12. The rotating shaft 14 and the annular elastic sheet 16 on the buffer gear 15 rotate in the assembly ring 17. After the movement of the rectangular mounting seat 8 and the U-shaped connecting frame 9 stops, the rotating shaft 14 and the assembly ring 17 also stop in the assembly ring 17. During the rotation of the annular elastic sheet 16, the annular elastic sheet 16 will deform and the pressure generated by contacting the assembly ring 17 is small. When it stops, the annular elastic sheet 16 returns to its original shape and continues to contact and friction with the assembly ring 17, generating a reverse force to block the continued rotation of the rotating shaft 14 and the annular elastic sheet 16, thereby reducing the force generated by the moving inertia of the rectangular mounting seat 8 and the U-shaped connecting frame 9.

[0037] A fixed frame 18 is arranged inside the machine tool body 1. A servo motor 19 is fixedly installed on the fixed frame 18. A driving gear 20 is fixedly installed on the output shaft of the servo motor 19. The driving gear 20 meshes with a rack 21 arranged at the bottom of the lower assembly plate 5. The fixed frame 18 supports the servo motor 19 to assist in the installation of the servo motor 19. The output shaft of the servo motor 19 drives the driving gear 20 to rotate, driving the rack 21 to move, thereby driving the lower assembly plate 5 and the upper assembly plate 6 to move on the inner insert assembly plate 4.

[0038] Reference Figure 6 , a fixture tooling is arranged at the top of the second movable cover 38. A milling cutter is installed through the action of the fixture tooling. By changing the position of the milling cutter, the processing of the copper rod is realized. The copper rod is conveyed into the machine tool body 1 through a conveyor;

[0039] Reference Figure 4 、 Figure 5 Inside the machine tool body 1, a dust and chip collection groove 22 is vertically opened. An inclined dust and chip guiding groove 23 is opened in the machine tool body 1, and the dust and chip collection groove 22 and the dust and chip guiding groove 23 are communicated with each other. The dust and chip collection groove 22 is a trapezoidal groove for guiding, and the dust and chip guiding groove 23 is a guiding groove to assist the movement of copper chips.

[0040] A fixed rectangular frame 24 is fixedly installed in the dust and chip collection groove 22. An active rectangular frame 25 is placed above the fixed rectangular frame 24. The positions of the fixed rectangular frame 24 and the active rectangular frame 25 correspond to each other, and the active 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 active rectangular frame 25, and semi-circular grooves corresponding to the rotating rod 26 are provided on both the fixed rectangular frame 24 and the active rectangular frame 25. Through the cooperation of the semi-circular grooves on the fixed rectangular frame 24 and the active rectangular frame 25, the rotating rod 26 is movably clamped on the fixed rectangular frame 24 and the active rectangular frame 25. According to the size of the copper insert, a suitable number of rotating rods 26 are selected to ensure the support effect while not affecting the falling of copper chips. A plurality of anti-slip sleeves 27 are movably sleeved on the rotating rod 26, and the anti-slip sleeves 27 position and fix the copper insert.

[0041] The semi-circular grooves on the fixed rectangular frame 24 and the active rectangular frame 25 correspond to each other in position, and the semi-circular grooves on the fixed rectangular frame 24 and the active rectangular frame 25 are equidistantly arranged to ensure the spacing between the rotating rods 26 and the installation stability of the rotating rods 26.

[0042] Reference Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 On the top of the upper assembly plate 6, a telescopic rod 29 is provided. The top end of the telescopic rod 29 is fixedly installed with a top mounting seat 30. An assembly seat 28 is also provided on the top of the upper assembly plate 6. An electric push rod 2801 is further provided on the top of the assembly seat 28. The end of the piston rod of the electric push rod 2801 supports at the corresponding position at the bottom of the top mounting seat 30. The piston rod of the electric push rod 2801 presses on the top mounting seat 30 to push the top mounting seat 30 to lift and lower, adapting to the frequent lifting and lowering control of the top mounting seat 30.

[0043] A circular fixed shaft 31 is provided at the top of the assembly seat 28. A locking nut 32 is rotatably connected to the circular fixed shaft 31. A threaded rod 33 is connected to the locking nut 32 by internal threads. 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.

[0044] A first movable cover 37 is slidably connected to the outside of the top mounting seat 30. A second movable cover 38 is slidably connected to the outside of the first movable cover 37. First limiting rods 39 are arranged in the grooves on both sides of the top mounting seat 30. First limiting end strips 40 corresponding to the first limiting rods 39 are arranged on the inner wall of the first movable cover 37. The first limiting end strips 40 limit the ends of the first limiting rods 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. Second limiting end strips 42 corresponding to the ends of the second limiting rods 41 are arranged in the grooves on both sides of the first movable cover 37. The second limiting end strips 42 limit the ends of the second limiting rods 41 to prevent the second movable cover 38 from falling off the first movable cover 37.

[0045] Working principle:

[0046] First step: According to the height requirement of cutting, 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 frequent adjustment is needed, turn the locking nut 32 to separate the locking nut 32 from the threaded rod 33, and drive the top mounting seat 30, the first movable cover 37 and the second movable cover 38 to rise and fall through 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 it is not necessary to frequently adjust the height of the structure composed of the top mounting seat 30, the first movable cover 37 and the second movable cover 38, thread the locking nut 32 onto the threaded rod 33, and adjust the height of the structure composed of the circular fixed shaft 31 and the threaded rod 33 by rotating the locking nut 32 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, ensuring that the structure on the second movable cover 38 can work better.

[0047] Second step: By rotating the locking bolt 36, fix the scale 35 on the fixed buckle 34. According to the scale on the scale 35, observe the distance between the top mounting seat 30 and the assembly seat 28 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.

[0048] Step 3: When adjusting the lateral position of the structure on the second movable cover 38, 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 inside the second movable cover 38 moves in the grooves on both sides of the first movable cover 37. 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, ensuring 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 on the first movable cover 37 when the second movable cover 38 moves 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, ensuring that the first movable cover 37 does not fall off the top mounting seat 30. By the movement of the second movable cover 38 on the first movable cover 37 and the movement of 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.

[0049] Step 4: The output shaft of the servo motor 19 drives the driving gear 20 to move. Through the meshing of the driving gear 20 and the rack 21, the structure composed of the lower assembly plate 5 and the upper assembly plate 6 is driven to move on the inner interpolation 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 interpolation assembly plate 4, they will drive the rectangular mounting seat 8 and the U-shaped connecting frame 9 to move in the positioning frame 11. The rectangular mounting seat 8 and the U-shaped connecting frame 9 move outside the rectangular insert 12. Through the meshing of the buffer gear 15 rotatably connected to the rectangular mounting seat 8 and the tooth groove 13, when the rectangular mounting seat 8 and the U-shaped connecting frame 9 move outside the rectangular insert 12, the buffer gear 15 also rotates through the meshing with the rectangular insert 12. The rotating shaft 14 and the annular elastic piece 16 on the buffer gear 15 rotate in the assembly ring 17. After the movement of the rectangular mounting seat 8 and the U-shaped connecting frame 9 stops, the rotating shaft 14 and the assembly ring 17 also stop in the assembly ring 17. During the rotation of the annular elastic piece 16, the annular elastic piece 16 will deform and the pressure generated by contacting the assembly ring 17 is small. When it stops, the annular elastic piece 16 returns to its original shape and continues to contact and friction with the assembly ring 17, generating a reverse driving force to block the continuous rotation of the rotating shaft 14 and the annular elastic piece 16, thereby reducing the force generated by the moving inertia of the rectangular mounting seat 8 and the U-shaped connecting frame 9.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
