[0011] Beneficial effects

[0012] This invention provides a calibration and straightening frame. Compared with the prior art, it has the following advantages:

[0013] 1. This calibration and straightening frame, through the setting of an orientation adjustment and straightening mechanism, allows the roller to move horizontally left and right by rotating the horizontal adjustment screw, and the roller to move vertically by rotating the vertical adjustment screw. Rotating the worm gear causes the worm wheel to rotate, which in turn causes the rotating guide sleeve and rotating bracket to rotate, which in turn causes the roller to rotate. This achieves adjustment of the roller in the X, Y, and Z directions. After the profile passes through the roller and is limited by the roller, the deformed profile will be calibrated and straightened. This equipment has a simple and compact structure, low cost, and convenient adjustment.

[0014] 2. This calibration and straightening frame, by setting a rotation limiting mechanism, rotates the roller adjusting screw to adjust the position of the adjusting roller. Then, the insert is placed on the top of the roller adjusting screw. The top of the roller adjusting screw will press against the top block. The top block moves the moving rod, connecting block, and rubber block. The rubber block and rubber ring contact to generate friction, preventing the insert from rotating. This can limit the rotation of the roller adjusting screw and prevent the vibration generated when the adjusting roller rotates from causing the roller adjusting screw to reverse, thereby changing the position of the guide block and adjusting roller and affecting the straightening.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a calibration and straightening frame, including a rotating base 6, with an orientation adjustment and straightening mechanism 29 above the rotating base 6. The orientation adjustment and straightening mechanism 29 includes a sliding base plate 5, a horizontal adjusting screw 4, two guide shafts 1, a connecting plate 20, a straightening moving block 7, an up and down adjusting screw 13, a rotating guide sleeve 3, a worm gear 8, a worm 2, a rotating bracket 14, a fixed roller 16, and an adjusting roller 15. The bottom of the sliding base plate 5 and the top of the rotating base 6 are slidably connected. The right end of the adjusting screw 4 is fixedly connected to the left end of the sliding base plate 5. The left end of the horizontal adjusting screw 4 passes through the left side of the rotating base 6, and the rotating base 6 is screwed in. The bottom of the guide shaft 1 is fixedly connected to the top of the sliding base plate 5, and the top of the guide shaft 1 is fixedly connected to the bottom of the connecting plate 20. The guide shaft 1 passes through the straightening moving block 7 and is slidably connected to the straightening moving block 7. The bottom of the vertical adjusting screw 13 is rotatably connected to the top of the straightening moving block 7, and the top end of the vertical adjusting screw 13 passes through the connecting plate 20. It is screwed to the connecting plate 20. The rotating guide sleeve 3 is located inside the straightening moving block 7 and is rotatably connected to the straightening moving block 7. The front end of the rotating guide sleeve 3 is fixedly connected to the worm gear 8. The front surface of the straightening moving block 7 is rotatably connected to the worm 2. The front surface of the rotating bracket 14 is fixedly connected to the rear end of the rotating guide sleeve 3. The fixed roller 16 is installed on the rotating bracket 14 through two fixed blocks 10. Two guide blocks 9 are slidably connected inside the rotating bracket 14. The two ends of the adjusting roller 15 are rotatably connected to the two guide blocks 9. The top of the guide block 9 is rotatably connected to the roller adjusting screw 11. The outer wall of the roller adjusting screw 11 is screwed to the fixed block 10. The upper fixed block 10 is fixedly connected to the top of the rotating bracket 14. The top of the upper fixed block 10 is provided with a rotation limiting mechanism 12. The adjustment of the roller in the X, Y, and Z directions is realized through the horizontal adjusting screw 4, the vertical adjusting screw 13, the worm 2, and the worm gear 8. After the profile passes through the roller, it is limited by the roller, and the deformed profile is calibrated and straightened.

[0022] Furthermore, the rotation limiting mechanism 12 includes an insert 21, a fixed cylinder 19, a limiting rod 18, a tension spring 17, multiple top blocks 22, multiple fixing plates 23, multiple moving rods 24, multiple compression springs 28, multiple connecting blocks 27, multiple rubber blocks 26, and rubber rings 25. The bottom end of the limiting rod 18 is fixedly connected to the top of the upper fixing block 10. The limiting rod 18 passes through the fixed cylinder 19. The tension spring 17 is sleeved on the outside of the limiting rod 18, and its two ends are fixedly connected to the upper fixing block 10 and the fixed cylinder 19, respectively. The outer wall of the insert 21 is rotatably connected to the inner wall of the fixed cylinder 19. Multiple fixing holes 30 are opened on the outer wall of the insert 21, and the fixing plates 23 are fixed inside the fixing holes 30. The moving rod 24 passes through the fixed plate 23 and is slidably connected to the fixed plate 23. The two ends of the moving rod 24 are fixedly connected to the top block 22 and the connecting block 27, respectively. The connecting block 27 is fixedly connected to the rubber block 26. The rubber ring 25 is fixed inside the fixed cylinder 19. The compression spring 28 is sleeved on the outside of the moving rod 24 and located between the top block 22 and the fixed plate 23. When the insert 21 is sleeved on the top of the roller adjusting screw 11, the top of the roller adjusting screw 11 will squeeze the top block 22. The top block 22 moves the moving rod 24, the connecting block 27 and the rubber block 26. The rubber block 26 and the rubber ring 25 come into contact and generate friction, preventing the insert 21 from rotating. This can limit the rotation of the roller adjusting screw 11.

[0023] During operation, rotating the horizontal adjusting screw 4 allows the roller to move horizontally left and right, while rotating the vertical adjusting screw 13 allows the roller to move vertically. Rotating the worm gear 2 causes the worm wheel 8 to rotate, which in turn causes the rotating guide sleeve 3 and rotating bracket 14 to rotate. The rotating bracket 14 then rotates the roller, thus adjusting the roller in the X, Y, and Z directions. After the profile passes through the roller and is limited by the roller, the deformed profile is calibrated and straightened. After adjusting the position of the adjusting roller 15, the insert 21 is then placed on top of the roller adjusting screw 11. The top of the roller adjusting screw 11 presses against the top block 22, which moves the moving rod 24, connecting block 27, and rubber block 26. The rubber block 26 and rubber ring 25 come into contact, generating friction to prevent the insert 21 from rotating. This restricts the rotation of the roller adjusting screw 11 and prevents the vibration generated when the adjusting roller 15 rotates from causing the roller adjusting screw 11 to reverse, thereby changing the position of the guide block 9 and the adjusting roller 15 and affecting the straightening.
