Specific embodiments
[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. The embodiments of the present invention include but are not limited to the following embodiments.
[0031] Embodiment 1:
[0032] As Figure 1-8As shown in the figure, the processing fixture for tubular parts provided by the present utility model includes: a support frame 1, which is fixed on the working platform by bolts. A fixed frame 2 and a moving frame 3 are installed on the top of the support frame 1. Fixed mechanisms 4 are provided on both the fixed frame 2 and the moving frame 3. A driving component is provided between the fixed frame 2 and the moving frame 3 to control the distance between the two. The thin-walled tube 6 is fixed between the two fixed mechanisms 4. Hereinafter, the fixed mechanism 4 on the fixed frame 2 will be taken as an example for explanation. The fixed mechanism 4 includes a mounting plate 7 fixedly installed on the fixed frame 2. A plurality of inner support blocks 8 are installed on one side of the mounting plate 7. An arc surface adapted to the inner hole of the thin-walled tube 6 is provided on the outer side of the inner support blocks 8. A cylinder 9 is installed on the fixed frame 2. A linkage component is provided between the cylinder 9 and the inner support blocks 8. Through the linkage component, the cylinder 9 can drive all the inner support blocks 8 to move synchronously closer to or away from the center of the mounting plate 7. Two outer clamps 10 are symmetrically installed on the fixed frame 2. Bolts 11 are installed between the outer clamps 10 and the fixed frame 2. The end of the bolt 11 is rotatably connected to the outer clamp 10. A clamping groove 12 adapted to the outer diameter of the thin-walled tube 6 is provided on the outer clamp 10. During use, the moving frame 3 is controlled by the driving component to move away from the fixed frame 2 so that the distance between the two exceeds the length of the thin-walled tube 6. Then the cylinder 9 is started, and the inner support blocks 8 are driven by the linkage component to move synchronously closer to the center of the mounting plate 7. Then one end of the thin-walled tube 6 is sleeved on the outer side of the inner support blocks 8. Then the moving frame 3 is moved closer to the fixed frame 2 so that the other end of the thin-walled tube 6 is also sleeved on the outer side of the inner support blocks 8. Then the cylinder 9 is started to make the inner support blocks 8 move synchronously away from the center of the mounting plate 7 to tighten the thin-walled tube 6 from the inside. Then the bolt 11 is rotated to make the outer clamp 10 close to the outer wall of the thin-walled tube 6 until it tightly presses the outer wall of the thin-walled tube 6, thereby clamping and fixing the thin-walled tube 6 from the outside. Then, through the driving component, the moving frame 3 is moved to the side away from the fixed frame 2, thereby straightening the thin-walled tube 6, reducing the sag and bending in the middle, and further improving the punching accuracy.
[0033] By providing the support frame 1, the fixed frame 2, the moving frame 3 and the fixed mechanism 4, the two ends of the pipeline are clamped and fixed simultaneously from the inside and outside by the fixed mechanism 4, reducing the deformation at the clamping position, and the driving component is used to drive the moving frame 3 away from the fixed frame 2 to straighten the pipeline and reduce its bending arc, which is beneficial to improving the processing accuracy.
[0034] Embodiment 2:
[0035] As Figure 8 shown, a gasket 13 is installed on the clamping groove 11. During use, the gasket 13 contacts the outer wall of the thin-walled tube 6, which can reduce the indentation of the outer clamp 10 on the thin-walled tube 6 and prevent the thin-walled tube 6 from being deformed by pressure.
[0036] By providing that the gasket 13 is installed on the clamping groove 11, the indentation at the clamping position of the pipeline can be reduced, thereby improving the product quality.
[0037] Example 3:
[0038] As Figure 5-7 shown, a plurality of sliding grooves 14 are provided on the mounting disc 7, sliders 16 are installed in the sliding grooves 14, one side of the slider 16 is fixedly connected to the inner support block 8. During use, the inner support block 8 and the slider 16 move along the direction of the sliding groove 14 together, that is, move closer to or away from the center of the mounting disc 7.
[0039] By providing the sliding groove 14 and installing the slider 16, the moving direction of the inner support block 8 can be controlled.
[0040] Example 4:
[0041] As Figure 5-7 shown, the linkage assembly includes a rotating shaft 15 rotatably installed at one end of the mounting disc 7, the rotating shaft 15 is rotatably connected to the fixed frame 2 (moving frame 3), a plurality of linkage rods 17 are rotatably installed on the rotating shaft 15, the other end of the linkage rod 17 is rotatably connected to the slider 16, and a connecting rod 18 is installed between the rotating shaft 15 and the cylinder 9, the connecting rod 18 is rotatably connected to the rotating shaft 15. During use, when the cylinder 9 is started to make its output shaft extend, the rotating shaft 15 is rotated through the connecting rod 18, and the rotating shaft 15 rotates through the linkage rod 17, so that all the sliders slide synchronously along the sliding groove 14, and further the inner support block 8 moves away from or close to the center of the mounting disc 7 synchronously.
[0042] By providing a linkage assembly including the rotating shaft 15, the linkage rod 17 and the connecting rod 18, the cylinder 9 can be used to drive the rotating shaft 15 to rotate, and the rotational motion of the rotating shaft 15 can be converted into the linear motion of the slider 16, so that the inner support block 8 moves away from or close to the center of the mounting disc 7 synchronously.
[0043] Example 5:
[0044] As Figure 1-3 shown, a guide groove 19 is provided at the top of the support frame 1, a guide strip 20 is provided at the bottom of the moving frame 3, and the guide strip 20 is slidably installed in the guide groove 19, so that the moving frame 3 moves along the direction of the guide groove 19.
[0045] By providing the guide groove 19 and the guide strip 20, the moving frame 3 is slidably connected to the support frame 1.
[0046] Example 6:
[0047] As Figure 3 shown, the driving assembly includes a driving motor 5 fixedly installed on one side of the fixed frame 2, a lead screw 21 is installed on the output shaft of the driving motor 5, and the lead screw 21 is connected to the moving frame 3. During use, the driving motor 5 is started to make the lead screw 21 rotate, and then the moving frame 3 moves closer to or away from the fixed frame 2.
[0048] By setting a driving assembly including a driving motor 5 and a lead screw 21, it is possible to conveniently drive the moving frame 3 to approach or move away from the fixed frame 2.
[0049] Embodiment 7:
[0050] As Figure 3 shown, two guide posts 22 are fixedly installed on one side of the fixed frame 2. The guide posts 22 penetrate through the moving frame 3. During use, the moving frame 3 moves along the axial direction of the guide posts 22, so that the movement of the moving frame 3 is more stable and has higher precision.
[0051] By setting two guide posts 22 installed on one side of the fixed frame 2, the movement stability of the moving frame 3 can be improved.
[0052] Working principle: During use, the driving assembly is used to control the moving frame 3 to move away from the fixed frame 2 so that the distance between the two exceeds the length of the thin-walled pipe 6. Then, the cylinder 9 is started, and the inner support blocks 8 are synchronously moved closer to the center of the mounting plate 7 through the linkage assembly. Then, one end of the thin-walled pipe 6 is sleeved outside the inner support blocks 8, and then the moving frame 3 is moved closer to the fixed frame 2 so that the other end of the thin-walled pipe 6 is also sleeved outside the inner support blocks 8. Then, the cylinder 9 is started to move the inner support blocks 8 synchronously away from the center of the mounting plate 7 to tighten the thin-walled pipe 6 from the inside. Then, the bolt 11 is rotated to move the outer fixture 10 closer to the outer wall of the thin-walled pipe 6 until it tightly presses against the outer wall of the thin-walled pipe 6, so as to clamp and fix the thin-walled pipe 6 from the outside. Then, through the driving assembly, the moving frame 3 is moved to the side away from the fixed frame 2, thereby straightening the thin-walled pipe 6, reducing the sag and bending in the middle, and thus improving the drilling precision.
[0053] It should be noted that other devices can be used to assist in supporting the bottom of the thin-walled pipe 6. This method is a conventional method and will not be elaborated here, which can further improve the drilling quality of the pipeline.
