Description

Technical Field

[0001] The utility model belongs to the technical field of steel processing, in particular to a cross column body calibration device. Background Art

[0002] During the assembly of a cross-shaped steel column, each component will have dimensional errors during the cutting process, and there will be gaps between them. To eliminate these gaps, dimensional calibration is required during and after the production process. Most calibration methods use a weight to press down on the flange plate. However, due to the heavy weight, the pressure must be lifted to a certain height and applied for a certain period of time, which poses a safety hazard.

[0003] An existing patent document (publication number: CN205200234U) discloses "a small welded H-beam pressure correction mold". Its technical solution is to apply pressure to the center of the web by a correction pressure rod to control overpressure. The reaction force on both sides of the support device causes the flange plate to deform upward, thereby achieving the purpose of correction. However, there are problems such as low accuracy, large error, and poor correction effect. Summary of the Invention

[0004] The purpose of the utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a cross column body calibration device with novel structure, wide application range, intelligent calibration, labor-saving and convenient operation, which can improve the qualified rate of components and avoid damage to the column body caused by multiple reworks.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A cross-column shaft calibration device includes a support frame equipped with a correction mechanism comprising a first telescopic mechanism and a second telescopic mechanism. A correction gap corresponding to the cross-column flange is formed between the first and second telescopic mechanisms. The first telescopic mechanism is used to press the flange downward for correction, while the second telescopic mechanism is used to lift the flange for correction. This calibration device features a novel structure, a wide range of applications, intelligent calibration, and labor-saving, convenient operation. It can improve component qualification rates and avoid damage to the column shaft caused by repeated rework.

[0007] Furthermore, a third telescopic mechanism is provided on the support frame and is connected to the correcting mechanism. This mechanism can drive the correcting mechanism downward, causing the second telescopic mechanism to come into contact with the transverse web of the cross column, eliminating the height difference between the two. The transverse web provides support for the second telescopic mechanism, enabling it to lift the flange plate above. This makes it suitable for cross columns of different heights and has strong applicability.

[0008] Furthermore, the output end of the third telescopic mechanism is connected to a mounting plate, and the first telescopic mechanism and the second telescopic mechanism are both arranged on the mounting plate, thereby improving the installation stability of the first telescopic mechanism and the second telescopic mechanism.

[0009] Furthermore, the second telescopic mechanism utilizes a scissor lift mechanism, which includes a base, a scissor brace, a drive screw, and a servo motor. The scissor brace is mounted on the base, and the servo motor is connected to the scissor brace via a drive screw. The scissor brace is equipped with a lifting head for lifting the flange plate. The servo motor rotates the drive screw, which in turn drives the scissor brace up and down. During lifting, the lifting head lifts the flange plate to correct it.

[0010] Furthermore, a distance sensor is slidably connected to the support frame. The distance sensor can be slid horizontally to change its measuring position, and can be flexibly adjusted according to different working conditions, with strong adaptability.

[0011] Furthermore, a slide rail is provided on the support frame, and the distance sensor is slidably connected to the slide rail via a slider, so the sliding is stable, not easy to deviate, and reliable to use.

[0012] Furthermore, the invention further includes a lifting platform for supporting the cross column. The lifting platform can drive the cross column up and down, thereby adjusting the height position of the cross column, reducing the height difference between the first telescopic mechanism, the second telescopic mechanism and the flange plate, and ensuring more complete contact, thereby improving the correction effect. The invention is applicable to cross columns of different heights and has strong applicability.

[0013] Furthermore, the lifting platform is equipped with a guide roller assembly, which includes a guide roller in contact with the cross column and a frame. The guide roller is rotatably connected to the frame. The guide roller and the cross column have rolling friction, which facilitates the position adjustment of the cross column, reducing labor intensity and being practical and convenient.

[0014] Furthermore, the bottom of the lifting platform is provided with running wheels, a transmission shaft is provided between the running wheels, a reduction motor is provided on the lifting platform, and a transmission assembly is connected between the reduction motor and the transmission shaft. The reduction motor drives the transmission shaft to rotate through the transmission assembly, thereby driving the running wheels to rotate, realizing the movement of the lifting platform, eliminating the need for manual handling, which is labor-saving and convenient.

[0015] Furthermore, the transmission assembly includes a first gear, a transmission chain, and a second gear. The transmission chain connects the first and second gears. The first gear is located at the output end of the reduction motor, and the second gear is located on the transmission shaft. The reduction motor drives the first gear to rotate, which in turn drives the second gear via the transmission chain, thereby driving the transmission shaft and the running wheels to rotate, achieving stable transmission and high reliability.

[0016] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0017] The utility model can correct a rigid cross column with large rigidity, eliminating the trouble of using heavy objects to press down the flange plate for size calibration in the prior art, and eliminating the trouble and danger when carrying heavy objects; the intelligent calibration is labor-saving and convenient, which can improve the qualification rate of components and avoid damage to the column body caused by repeated rework; the scope of application is wide, and it is not only suitable for the size calibration of standard rigid cross columns, but also suitable for the size calibration of variable-section rigid cross columns and steel components such as I-beams.

DETAILED DESCRIPTION

[0025] like Figures 1 to 5 As shown, the cross column body calibration device of the utility model includes: a support frame 1, a correction mechanism and a lifting platform 2, the correction mechanism includes a first telescopic mechanism 3 and a second telescopic mechanism 4, the first telescopic mechanism 3 is located above the second telescopic mechanism 4, and a correction gap corresponding to the flange plate 5 of the cross column is formed between the first telescopic mechanism 3 and the second telescopic mechanism 4. A third telescopic mechanism 6 is provided on the support frame 1, and the output end of the third telescopic mechanism 6 is connected to the mounting plate 7. The first telescopic mechanism 3 is fixed to the mounting plate 7 through a mounting seat 8, and the second telescopic mechanism 4 is fixed to the connecting arm 9 of the mounting plate 7, which improves the installation stability of the first telescopic mechanism 3 and the second telescopic mechanism 4.

[0026] The mounting plate 7 is provided with a slide rail 10, to which a slider 11 is slidably connected. A distance sensor 12 is fixed to the slider 11, and the distance sensor 12 is located near the first telescopic mechanism 3. The distance sensor 12 can be slid horizontally to change its measuring position, allowing for flexible adjustment according to different working conditions. It has strong adaptability, high sliding stability, is not prone to deviation, and is reliable in use.

[0027] A stepper motor can be provided on one side of the slide rail 10, with a screw connected to the output end of the stepper motor, which is screwed to the slider. When the stepper motor is started, the stepper motor drives the slider to slide via the screw, thereby accurately controlling the position of the distance sensor 12 and preventing the slider from sliding freely.

[0028] The first telescopic mechanism 3 and the third telescopic mechanism 6 can adopt electric cylinders, air cylinders or oil cylinders and other devices capable of adjusting their own lengths. The second telescopic mechanism 4 can adopt electric cylinders, air cylinders, oil cylinders, jacks or scissors lifting mechanisms, preferably a scissors lifting mechanism. The scissors lifting mechanism includes a base 13, a scissors strut 14, a transmission screw 15 and a servo motor 16. The scissors strut 14 is arranged on the base 13. The servo motor 16 is connected to the scissors strut 14 through the transmission screw 15. The top of the scissors strut 14 is provided with a lifting end 17 for lifting the flange plate 5.

[0029] A control processor 18 is installed on the support frame 1. The control processor 18 can be a single chip microcomputer. The control processor 18 is electrically connected to the first telescopic mechanism 3, the servo motor 16, the third telescopic mechanism 6, and the distance sensor 12 respectively.

[0030] The servo motor 16 drives the transmission screw 15 to rotate, and the transmission screw 15 drives the scissors support 14 to rise and fall. When rising, the flange plate 5 is lifted by the lifting end 17 to correct it.

[0031] The third telescopic mechanism 6 can drive the correction mechanism to descend, so that the second telescopic mechanism 4 conflicts with the transverse web of the cross column, eliminating the height difference between the two. The transverse web provides support to the second telescopic mechanism 4, so that the second telescopic mechanism 4 can lift the upper flange plate 5. It can be applied to cross columns of different heights and has strong applicability.

[0032] The lifting platform 2 is used to support the cross column. The lifting platform 2 can drive the cross column to rise and fall, and then adjust the height position of the cross column, reduce the height difference between the first telescopic mechanism 3, the second telescopic mechanism 4 and the flange plate 5, and make the contact more complete, thereby improving the correction effect. It can be applied to cross columns of different heights and has strong applicability.

[0033] The lifting platform 2 is provided with a guide roller assembly, which includes a guide roller 19 in contact with the cross column and a frame 20. The guide roller 19 is rotatably connected to the frame 20. There is rolling friction between the guide roller 19 and the cross column, which facilitates the position adjustment of the cross column, reduces labor intensity, and is practical and convenient.

[0034] A traveling wheel 21 is provided at the bottom of the lifting platform 2, and a transmission shaft 22 is provided between the traveling wheels 21. A reduction motor 23 is provided on the lifting platform 2, and a transmission assembly is connected between the reduction motor 23 and the transmission shaft 22. The transmission assembly includes a first gear, a transmission chain and a second gear 24. The transmission chain connects the first gear and the second gear 24. The first gear is provided at the output end of the reduction motor 23, and the second gear 24 is provided on the transmission shaft 22.

[0035] The reduction motor 23 drives the first gear to rotate, and the first gear drives the second gear 24 to rotate through the transmission chain, thereby driving the transmission shaft 22 to rotate, and the walking wheel 21 rotates accordingly, thereby realizing the movement of the lifting platform 2 without manual handling, saving labor and convenience, stable transmission and high reliability.

[0036] When in use, place the cross column on the lifting platform 2, push the cross column horizontally, and place the flange plate 5 on the vertical web in the correction gap. After starting up, the control processor 18 controls the third telescopic mechanism 6 to start, and the third telescopic mechanism 6 drives the mounting plate 7 to descend, and the second telescopic mechanism 4 follows and descends until the base 13 contacts the upper surface of the transverse web, and then starts the distance sensor 12. The distance sensor 12 measures the distance between itself and the upper surface of the flange plate 5 below, obtains the closest distance D1, and sends it to the control processor 18. The control processor 18 compares D1 with the preset standard distance D to obtain the difference. If the difference is negative, indicating concave, the control processor 18 controls the servo motor 16 to start, the servo motor 16 drives the scissors support 14 to rise through the transmission screw 15, and lifts the lower surface of the flange plate 5 through the lifting end 17 to correct the flange plate 5; if the difference is positive, indicating convex, the control processor 18 controls the first telescopic mechanism 3 to start, and the output end of the first telescopic mechanism 3 descends, so that it presses down the upper surface of the flange plate 5 to correct the flange plate 5.

[0037] The utility model can correct a rigid cross column with large rigidity, eliminating the trouble of using a heavy object to press down the flange plate 5 for size calibration in the prior art, and eliminating the trouble and danger when carrying heavy objects; intelligent calibration can improve the qualification rate of components and avoid damage to the column body caused by repeated rework; the scope of application is wide, and it is not only applicable to the size calibration of standard rigid cross columns, but also to the size calibration of variable-section rigid cross columns and steel components such as I-beams.
