[0002] A long tube lathe is a type of lathe specifically designed for machining long tube parts. It is widely used in industries such as machinery manufacturing, petroleum, chemical, coal, geological exploration, and urban water supply and drainage.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown in this embodiment, a long tube lathe machining tilting bracket includes a base 1. Two sets of mounting brackets 2 are provided above the base 1. Mounting seats 4 are rotatably mounted on the mounting brackets 2. Mounting rings 5 are rotatably mounted inside the mounting seats 4. Gear rings 6 are fixedly sleeved on the mounting rings 5. A first rack 7 is slidably mounted inside the mounting seats 4. Ring teeth 9 are fixedly mounted on the mounting rings 5. Three sets of annularly distributed cover plates 18 are provided on the mounting seats 4. Three sets of annularly distributed sliders 10 are provided between the mounting seats 4 and the cover plates 18. The three sets of sliders 10 are slidably connected to the cover plates 18. All three sets of sliders 10 are engaged with the mounting rings 5 via ring teeth 9. Clamping rods 11 are fixedly mounted on each of the three sets of sliders 10. A telescopic rod 12 is slidably installed inside the mounting base 4. Four sets of symmetrically distributed abutment plates 14 are arranged around the telescopic rod 12. Suction cups 15 are fixedly installed on each of the four sets of abutment plates 14. Two sets of intersecting first brackets 16 and second brackets 17 are provided between each of the four sets of abutment plates 14 and the telescopic rod 12. Two sets of symmetrically distributed ratchet wheels 19 are sleeved on the mounting base 4. Two sets of symmetrically distributed pawls 20 are provided inside the mounting frame 2. The two sets of pawls 20 are respectively arranged corresponding to the ratchet wheels 19 and are engaged with them. When the cylinder 8 inside the mounting base 4 drives the first rack 7 to slide, it cooperates with the first toothed ring 6 to rotate the mounting ring 5. The mounting ring 5 drives the ring tooth 9 to rotate. Under the limiting action of the cover plate 18, three sets of sliders 10... The three sets of clamping rods 11 slide synchronously inward or outward on the mounting base 4, thereby adjusting the distance between them and ensuring that they fit against the outer wall of the tubular workpiece. The right-side mounting bracket 2 is slidably connected to the base 1, and the left-side mounting bracket 2 is fixedly connected to the base 1. A lead screw 3 is rotatably installed inside the base 1, passing through the right-side mounting bracket 2 and threadedly connected to it. The first rack 7 meshes with the gear ring 6. A cylinder 8 is installed inside the mounting base 4, and the first rack 7 is connected to the output end of the piston rod of the cylinder 8. A screw 13 is rotatably installed inside the mounting base 4, passing through the telescopic rod 12 and threadedly connected to it. The left end of the first bracket 16 is rotatably connected to the mounting base 4 via a rotating shaft. The right end of the first bracket 16 is slidably connected to the abutment plate 14, and the left end of the second bracket 17 is rotatably connected to the abutment plate 14 via a rotating shaft. The right end of the second bracket 17 is rotatably connected to the telescopic rod 12 via a rotating shaft. When the motor inside the mounting base 4 drives the screw 13 to rotate, the telescopic rod 12 slides in the mounting base 4 under the limiting action of the mounting base 4, thereby changing the adjustment of the support angle of the first bracket 16 and the second bracket that are cross-distributed between the abutment plate 14 and the telescopic rod 12, realizing the adjustment of the distance between the four sets of abutment plates 14, so that the suction cup 15 on the abutment plate 14 fits against the inner wall of the tubular workpiece, completing the firm fixation of the tubular workpiece. Compared with the traditional bracket, this bracket device has more fixing points and greater strength, avoiding the displacement of the tubular workpiece during processing.
[0023] like Figure 4 and Figure 5As shown, the two sets of ratchet pawls 20 are rotatably connected to the mounting frame 2 via rotating rods 21. A torsion spring 22 is sleeved on the rotating rod 21, and both ends of the torsion spring 22 are fixedly connected to the ratchet pawl 20 and the mounting frame 2, respectively. Gears 23 are sleeved on both sets of rotating rods 21. Two sets of second racks 32 are slidably installed inside the mounting frame 2, and the two sets of second racks 32 are respectively meshed with corresponding gears 23. The two sets of second racks 32 are fixedly connected to each other via a movable frame 24. A sleeve rod 25 is fixedly installed on the movable frame 24, and the sleeve rod 25 is slidably connected to the mounting frame 2. A first spring 26 is sleeved on the sleeve rod 25, and both ends of the first spring 26 are fixedly connected to the sleeve rod 25 and the mounting frame 2, respectively. A stop block 27 is fixedly sleeved on the sleeve rod 25, and an insert block 28 is slidably sleeved on the sleeve rod 25, with the insert block 28 located above the stop block 27. The top end of the sleeve rod 25 can be movably engaged with the insert block 28. A second spring 29 is provided between the insert block 28 and the top end of the sleeve rod 25, with both ends of the second spring 29 fixedly connected to the sleeve rod 25 and the insert block 28, respectively. A wedge-shaped locking rod 30 is slidably installed inside the mounting frame 2, and a third spring 31 is sleeved on the wedge-shaped locking rod 30. Both ends of the third spring 31 are fixedly connected to the wedge-shaped locking rod 30 and the mounting frame 2, respectively. The wedge-shaped locking rod 30 is movably engaged with the top end of the sleeve rod 25 and the insert block 28, respectively. When the sleeve rod 25 is pushed upward by the moving frame 24, it engages with the vertically opposite... The wedge-shaped locking rod 30, which is set vertically, is pushed to the right. The wedge-shaped locking rod 30 slides to the right and squeezes the third spring 31 until the sleeve rod 25 is above the wedge-shaped locking rod 30. Under the action of the third spring 31, the wedge-shaped locking rod 30 extends. Since the top of the sleeve rod 25 is flush with the bottom, the sleeve rod 25 is blocked by the wedge-shaped locking rod 30 and cannot move downward. During this process, the two sets of second racks 32 fixedly connected to the moving frame 24 slide synchronously in the mounting frame 2. The two sets of gears 23 meshing with them drive the corresponding rotating rod 21 and pawl 20 to rotate, deviating from the corresponding ratchet 19 and releasing the limit on the ratchet 19. At this time, the mounting seat 4 can rotate freely on the mounting frame 2, completing the flipping of the processed surface of the tubular workpiece. Then, the sleeve is pushed upward again by the moving frame 24. The insert 28 on the sleeve rod 25 slides upward synchronously until it contacts the wedge-shaped locking rod 30. During this upward sliding motion, the insert 28 pushes the wedge-shaped locking rod 30 to the right. Once the insert 28 is above the wedge-shaped locking rod 30, the wedge-shaped locking rod 30 extends under the action of the third spring 31, moving the sleeve rod 25 downward until the insert 28 contacts the wedge-shaped locking rod 30 and is pushed into the top of the sleeve rod 25, engaging with it. Because the insert 28 is rounded, continuing to push the moving rod downward allows the sleeve rod 25 and the insert 28 to smoothly push the wedge-shaped locking rod 30 to the right, enabling both the top of the sleeve rod 25 and the insert 28 to move smoothly to the lower end of the wedge-shaped locking rod 30. At this point, under the action of the torsion spring 22, the rotating rod 21 and the gear 23 return to their original positions.The pawl 20 engages with the ratchet 19 again. Under the action of the pawl 20 and the ratchet 19, the mounting base 4 cannot rotate, and the tubular workpiece is fixed in place.
[0024] This utility model provides a turning support for long tube lathe machining. The specific working principle is as follows: When the cylinder 8 inside the mounting base 4 drives the first rack 7 to slide, it cooperates with the first toothed ring 6 to rotate the mounting ring 5. The mounting ring 5 drives the ring tooth 9 to rotate. Under the limiting action of the cover plate 18, the three sets of sliders 10 slide synchronously inward or outward on the mounting base 4, thereby adjusting the distance between the three sets of clamping rods 11, so that the three sets of clamping rods 11 fit against the outer wall of the tubular workpiece. When the motor inside the mounting base 4 drives the screw 13 to rotate, under the limiting action of the mounting base 4, the telescopic rod 12 slides in the mounting base 4, thereby changing the cross-distribution of the first support 16 and the second support 12 between the abutment plate 14 and the telescopic rod 12. The angle of the support bracket is adjusted to adjust the spacing between the four sets of abutment plates 14, allowing the suction cups 15 on the abutment plates 14 to fit against the inner wall of the tubular workpiece, thus firmly fixing the tubular workpiece. Compared with traditional brackets, this support device has more fixing points and greater strength, preventing the tubular workpiece from shifting during processing. When the sleeve rod 25 is pushed upward by the moving frame 24, it pushes the wedge-shaped locking rod 30, which is perpendicular to it, to the right. The wedge-shaped locking rod 30 slides to the right and squeezes the third spring 31 until the sleeve rod 25 is above the wedge-shaped locking rod 30. Under the action of the third spring 31, the wedge-shaped locking rod 30 extends. Since the top of the sleeve rod 25 is flush with the bottom, the sleeve rod 25 is wedged at this time. The wedge-shaped locking lever 30 prevents downward movement. During this process, the two sets of second racks 32 fixedly connected to the moving frame 24 slide synchronously in the mounting frame 2. The two sets of gears 23 meshing with them drive the corresponding rotating rod 21 and pawl 20 to rotate, deviating from the corresponding ratchet 19 and releasing the limit on the ratchet 19. At this time, the mounting seat 4 can rotate freely on the mounting frame 2, completing the flipping of the processed surface of the tubular workpiece. Then, the moving frame 24 pushes the sleeve rod 25 upward again. The insert 28 on the sleeve rod 25 slides upward synchronously until the insert 28 contacts the wedge-shaped locking lever 30. During the upward sliding of the insert 28, the wedge-shaped locking lever 30 is pushed to the right. The insert 28 is located on the wedge-shaped locking lever 30. The upper rear wedge-shaped locking rod 30 extends under the action of the third spring 31, and moves the sleeve rod 25 downward until the insert 28 contacts the wedge-shaped locking rod 30 and is pushed into the top of the sleeve rod 25 and engages with the top of the sleeve rod 25. Since the insert 28 is smooth, the moving rod continues to be pushed downward, and the sleeve rod 25 and the insert 28 can smoothly push the wedge-shaped locking rod 30 to the right, so that the top of the sleeve rod 25 and the insert 28 can move smoothly to the lower end of the wedge-shaped locking rod 30. At this time, under the action of the torsion spring 22, the rotating rod 21 and the gear 23 return to their original positions, and the pawl 20 engages with the ratchet 19 again. Under the action of the pawl 20 and the ratchet 19, the mounting base 4 cannot rotate, and the tubular workpiece is fixed in position.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
