Description

Technical Field

[0001] This invention relates to the field of CNC composite machine technology, specifically a horizontal CNC lifting six-axis composite machine. Background Technology

[0002] A CNC composite machine is an automated machining equipment that integrates multi-axis control, multi-power synchronous drive, and multi-process composite machining. It can complete various machining actions such as milling, drilling, tapping, and chamfering in a single clamping. Zinc alloy tees are tee fittings made of zinc alloy as the base material and formed by die casting. They are mainly used in fluid transportation systems, HVAC pipelines, bathroom hardware, and pneumatic and hydraulic pipelines, serving as diversion, merging, and reversing functions. They are commonly used key connecting components in industrial and civil piping systems. Zinc alloys have advantages such as low melting point, excellent casting performance, good fluidity, high forming precision, and excellent surface finish. They also possess good machinability, mechanical strength, and corrosion resistance, meeting the requirements of tee fittings in terms of structural strength, sealing accuracy, and long-term stability. Therefore, they have become a commonly used material for manufacturing tee fittings.

[0003] During the machining of zinc alloy tees, due to their irregular shape and the fact that the three pipe openings are distributed at different angles and the outer wall of the pipe openings is a curved surface, the traditional clamping method often uses upper and lower pressure plates to directly clamp them. Because the pipe openings of zinc alloy tees are curved, the contact area between the flat pressure plate and the curved pipe opening is small and the clamping stability is poor. Under the action of cutting forces such as milling, drilling, and tapping, the workpiece is prone to shaking, displacement, and rotation.

[0004] Therefore, we proposed a horizontal CNC lifting six-axis composite machine to solve the above problems. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a horizontal CNC lifting six-axis composite machine, which solves the problems mentioned in the background art regarding the machining of zinc alloy tees. Due to the irregular shape of the tee, the three pipe openings are distributed at different angles, and the outer wall of the pipe openings is a curved surface. Traditional clamping methods often use upper and lower pressure plates to directly clamp the tee. However, because the zinc alloy tee pipe openings are curved, the contact area between the flat pressure plate and the curved pipe opening is small, resulting in poor clamping stability. Under the cutting forces of milling, drilling, tapping, etc., the workpiece is prone to shaking, shifting, and rotating.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0009] A horizontal CNC lifting six-axis composite machine includes a CNC composite machine base, three sets of power head assemblies mounted on the CNC composite machine base, and a processing head for machining zinc alloy tees on the power head assemblies. The CNC composite machine base is equipped with a processing seat for supporting the zinc alloy tee and a top support plate for the processing seat. The support plate has an outwardly expanding positioning adjustment seat on its outer side. A support sleeve is installed in the cavity of the adjustment groove on the positioning adjustment seat. An adjustment side plate is installed at the top opening of the support sleeve. Contact plates are installed at the V-shaped ends of the adjustment side plate. An adjustment mechanism is installed in the cavity of the support sleeve to adjust the unfolding angle of the adjustment side plate. The spacing of the contact plates can be adapted to different pipe root positions through the adjustment mechanism.

[0010] The top of the adjusting side plate is fixed with an assembly side plate, wherein a contact plate is installed between the opposing assembly side plates, and the contact plate has a semi-cylindrical structure.

[0011] Furthermore, the outer wall of the machining seat is provided with an outer ring groove, and one end of the positioning adjustment seat adopts an arc-shaped part that is adapted to the outer ring groove. The arc-shaped part can adjust the position of the positioning adjustment seat by moving in a ring along the outer ring groove. The machining seat is also provided with a positioning hole, and the bottom of the arc-shaped part is fixed with a downwardly extending positioning block. The positioning block is provided with a limiting hole corresponding to the positioning hole.

[0012] Furthermore, the machining base is provided with a limiting ring groove that communicates with the outer ring groove. The end of the limiting ring groove is provided with a notch. The top surface of the arc-shaped part of the positioning adjustment base is fixed with an anti-fall block. The anti-fall block can be inserted into the groove of the bearing plate and move along the groove of the limiting ring groove.

[0013] Furthermore, the bottom of the positioning and adjusting seat is provided with a threaded bottom cylinder, and a self-locking trapezoidal threaded rod is screwed into the threaded bottom cylinder. The top of the threaded rod is rotatably connected to the bottom of the support sleeve and is axially limited.

[0014] Furthermore, the adjustment mechanism includes a main support plate and a top convex plate. The main support plate is installed on the bottom sides of the adjustment side plate, and the top convex plate is fixed on the top of the main support plate. The top convex plate has two sets of spaced circular holes. The bottom ends of the top convex plate are fixed with shafts that can be rotatably inserted into the circular holes. The inner wall of the support sleeve has a longitudinal groove, and the side of the main support plate has a slider that is slidably embedded in the groove.

[0015] Furthermore, a top plate is fixed to the top surface of the support sleeve, a positioning bending rod is inserted into the side of the top plate, and an anti-detachment back plate is fixed to the back of the adjusting side plate, so that a U-shaped groove is formed between the adjusting side plate and the anti-detachment back plate, and the bent part of the positioning bending rod is inserted into the U-shaped groove.

[0016] Furthermore, a bottom inclined groove is provided at the bottom of the main support board, and an inclined slide bar is fixed at the bottom of the groove. Multiple sets of bottom inclined grooves are evenly distributed along the long axis end of the main support board.

[0017] Furthermore, the surface of the inclined slide bar is slidably connected to an inclined slider, the bottom of the inclined slider is fixedly provided with a threaded sleeve, and a high-strength self-locking threaded rod is provided inside the support sleeve, which is synchronously connected with multiple threaded sleeves.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example

[0035] like Figure 1-10As shown, an embodiment of the present invention proposes a horizontal CNC lifting six-axis composite machine, including a CNC composite machine base 1, three sets of power head assemblies 2 installed on the CNC composite machine base 1, and a processing head 3 for processing zinc alloy tees provided on the power head assemblies 2. The three sets of power head assemblies 2 are distributed in a C-shape to form a processing area. The front side of the CNC composite machine base 1 is an operation area, which is used for observation and loading and unloading of zinc alloy tees. The CNC composite machine base 1 includes a processing seat 11 for supporting zinc alloy tees, located between the C-shaped power head assemblies 2. The top of the processing seat 11 is a support plate 12 for supporting the tee. A pad 10 is fixed at the bottom of the processing seat 11, and cross bracing beams 4 are fixed at both ends of the pad 10. The CNC composite machine base 1 also includes multiple longitudinally arranged limiting columns 5. The ends of the cross bracing beams 4 are fitted onto the limiting columns 5, which longitudinally slide and limit the cross bracing beams 4. A pressing cylinder assembly 6 is bolted to the top of the limiting columns 5, and the output end of the pressing cylinder assembly 6 is connected to a pressing plate 7, so that the pressing plate 7 can be pressed against the upper surface of the zinc alloy tee during actual use. The base of the CNC composite machine base 1 also includes a hydraulic lifting mechanism that can drive the pad 10 to move longitudinally.

[0036] The support plate 12 has an outwardly extended positioning adjustment seat 16 on its outer side. To allow the positioning adjustment seat 16 to be adjusted according to the different shapes of the tee, an outer ring groove 13 is opened on the outer wall of the processing seat 11. The front end of the positioning adjustment seat 16 is arc-shaped, which matches the curvature of the outer ring groove 13, so that the front end of the positioning adjustment seat 16 is attached to the surface of the outer ring groove 13 and can move around the surface of the outer ring groove 13 in a ring, thereby adjusting the position of the positioning adjustment seat 16. In order to lock the position of the positioning adjustment seat 16 after adjustment, a positioning block 18 is fixed downward below the arc-shaped part of the positioning adjustment seat 16, and a limiting hole 19 is fixed on the positioning block 18. An annularly distributed positioning hole 20 is provided below the outer ring groove 13, and each positioning hole 20 has an internal thread. After the positioning adjustment seat 16 is moved to the specified angle, it is aligned with the positioning hole 20 through the limiting hole 19. Then, the bolt passes through the limiting hole 19 and is screwed into the corresponding positioning hole 20 to lock the positioning block 18 on the machining seat 11, thereby limiting the angle of the positioning adjustment seat 16.

[0037] To further improve the stability of the engagement between the positioning adjustment seat 16 and the machining seat 11, a limiting ring groove 15 is provided above the outer ring groove 13, and a notch groove 14 is provided on the side of the limiting ring groove 15. Simultaneously, an anti-fall block 17 is fixed to the top surface of the arc-shaped portion of the positioning adjustment seat 16. The anti-fall block 17 can be inserted into the notch groove 14 and can move within the notch groove 15. Therefore, during actual assembly, when the positioning adjustment seat 16 is pushed horizontally into the outer ring groove 13, the anti-fall block 17 needs to be aligned with the notch groove 14. After the anti-fall block 17 is inserted into the notch groove 14, it adheres to the inner wall of the limiting ring groove 15. At this time, the arc-shaped portion of the positioning adjustment seat 16 adheres to the surface of the outer ring groove 13. Thus, when adjusting the position of the positioning adjustment seat 16, the anti-fall block 17 is engaged in the notch groove 15, preventing the positioning adjustment seat 16 from falling.

[0038] As described above, the positioning adjustment seat 16 has an adjustment groove 21, in which a support sleeve 23 is fitted, and the support sleeve 23 can move longitudinally within the adjustment groove 21; and a threaded bottom cylinder 22 is provided at the bottom of the positioning adjustment seat 16, in which a self-locking threaded rod can be screwed in, the top of the threaded rod is rotatably connected to the bottom of the support sleeve 23 and is axially limited, and the height of the support sleeve 23 in the adjustment groove 21 can be adjusted by the threaded rod.

[0039] The top opening of the support sleeve 23 features a V-shaped adjusting side plate 26. Contact plates 35 are installed at both ends of the V-shape of the adjusting side plate 26. The contact plates 35 have a semi-cylindrical structure, with their flat surfaces designed to contact the root of the tee pipe opening. A wear-resistant layer can be added to the flat surface area. The cavity of the support sleeve 23 is equipped with an adjusting mechanism that allows for adjustment of the unfolding angle of the adjusting side plate 26. This mechanism allows the spacing of the contact plates 35 to adapt to different pipe opening roots. Since different tee pipes have varying diameters, two sets of adjustable-spacing contact plates 35 are designed to provide precise support to the bottom of the pipe opening from both sides. When the pipe diameter is larger, the two sets of contact plates 35 are closer to the sides; conversely, when the pipe diameter is smaller, the two sets of contact plates 35 are moved closer together.

[0040] In the above description, the adjustment mechanism includes a main support plate 27 and a top protrusion plate 28. The main support plate 27 is installed on both sides of the bottom of the adjustment side plate 26, and the top protrusion plate 28 is fixed on the top of the main support plate 27. The top protrusion plate 28 has two sets of spaced-apart circular holes. Shafts that can be rotatably inserted into the circular holes are fixed at both ends of the bottom of the adjustment side plate 26. The inner wall of the support sleeve 23 has a longitudinal sliding groove, and a slider that slides into the groove has a side surface of the main support plate 27. By moving the main support plate 27 longitudinally, the included angle of the adjustment side plate 26 can be adjusted. When the main support plate 27 moves upward, the included angle of the adjustment side plate 26 increases, increasing the distance between the two sets of contact plates 35; conversely, the distance between the two sets of contact plates 35 decreases. The top surface of the support sleeve 23 is fixed with a top plate 24, and a positioning bending rod 25 is inserted into the side of the top plate 24. The back of the adjusting side plate 26 is fixed with an anti-detachment back plate 38, so that a U-shaped groove is formed between the adjusting side plate 26 and the anti-detachment back plate 38. The bent part of the positioning bending rod 25 is inserted into the U-shaped groove and into the groove of the anti-detachment back plate 38 through the bent part of the positioning bending rod 25. During the angle adjustment of the adjusting side plate 26, the adjusting side plate 26 is limited.

[0041] like Figure 8 As shown, the bottom of the main support plate 27 has a bottom inclined groove 29, and a sliding strip 30 is fixed at the bottom of the groove 29. Multiple sets of the bottom inclined groove 29 are evenly distributed along the long axis of the main support plate 27. A sliding block 31 is slidably connected to the surface of the sliding strip 30, and a threaded sleeve 32 is fixed at the bottom of the sliding block 31. A high-strength self-locking threaded rod 33 is provided inside the support sleeve 23, synchronously connected to multiple threaded sleeves 32. One end of the high-strength self-locking threaded rod 33 is rotatably connected to the inner wall of the support sleeve 23, and the other end of the high-strength self-locking threaded rod 33 extends outward through the support sleeve 23 to form a handle. That is, by rotating the handle, the high-strength self-locking threaded rod 33 rotates, and the rotation of the high-strength self-locking threaded rod 33 causes multiple threaded sleeves 32 to move synchronously. The movement of the threaded sleeves 32 pushes the sliding block 31, thereby adjusting the height of the entire main support plate 27. Stability is achieved through the self-locking of the high-strength self-locking threaded rod 33.

[0042] A mounting side plate 34 is fixedly mounted on the top of the adjusting side plate 26, with a contact plate 35 installed between the opposing mounting side plates 34. The contact plate 35 has a semi-cylindrical structure. Side shafts 36 are fixed at both ends of the contact plate 35, with the front end of the side shaft 36 rotatably extending into the cavity of the mounting side plate 34. The front end of the side shaft 36 has a threaded hole. A gravity block 37 is mounted inside the cavity of the mounting side plate 34. The top of the gravity block 37 is bolted to the front end of the side shaft 36, keeping the flat part of the semi-cylindrical section vertically upward. The gravity block 37 is detachably mounted on the side shaft 36. In actual use, even if the included angle of the adjusting side plate 26 is adjusted, the gravity block 37 will fall downward under the action of gravity, keeping the flat part of the contact plate 35 facing upward. The positioning holes on the side of the mounting side plate 34 are used for assembly with the side cover plate.

[0043] Working principle: When the equipment is working, the zinc alloy tee workpiece is first placed on the support plate 12 on the top of the processing base 11. The lowering cylinder assembly 6 drives the lowering plate 7 to press the upper end face of the workpiece, keeping the workpiece in a fixed state during processing. According to the actual position of the workpiece tube opening, the positioning adjustment seat 16 is rotated to a suitable angle along the outer ring groove 13 on the outer wall of the processing base 11. Then, the positioning block 18 is locked with the positioning hole 20 by bolts to keep the support mechanism stable. At the same time, the anti-fall block 17 is engaged in the limiting ring groove 15 to prevent the positioning adjustment seat 16 from falling or loosening. By rotating the self-locking threaded rod in the threaded bottom cylinder 22, the support sleeve 23 can be moved up and down in the adjustment groove 21 to adjust the support height so that it matches the height of the root of the workpiece tube opening. Rotating the handle on the outside of the support sleeve 23 drives the high-strength self-locking threaded rod 33 to rotate, which in turn moves the threaded sleeve 32 and the inclined slider 31 along the inclined slide bar 30, pushing the bearing main plate 27 up and down. This changes the V-shaped opening angle of the adjusting side plate 26, allowing the distance between the two end contact plates 35 to adapt to the root of pipes with different diameters, achieving precise support. The contact plate 35 adopts a semi-cylindrical structure, and under the action of the side shaft rod 36 and the gravity block 37, it always maintains a flat upward plane due to gravity. No matter how the V-shaped angle of the adjusting side plate 26 is adjusted, it can stably fit the bottom of the pipe opening, ensuring uniform support force. The three sets of power head assemblies 2 are distributed in a C-shape on the CNC composite machine base 1. Together with the hydraulic lifting mechanism, they drive the machining seat 11 to rise and fall, which can simultaneously perform composite processing such as milling, drilling, and tapping on multiple pipe openings of zinc alloy tees. Multiple processes can be completed in one clamping, effectively improving processing accuracy and production efficiency.

[0044] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
