[0029] To solve the technical problems in the background art, as shown in Figures 1-5 The present application provides a technical solution: a square tube correcting device, characterized as follows:
[0030] The fixed seat 1 is a hollow rectangular structure, and two guide rails 2 are arranged on the two sides of the fixed seat 1. The guide rails 2 are used to guide the movement of the sliding base 7, so as to ensure that the clamping mechanism 6 can smoothly slide along the two sides of the fixed seat 1. The correction wheel base 3 is arranged at the middle position of the fixed seat 1, and the bottom of the correction wheel base 3 is connected with the air cylinder 4. The air cylinder 4 is used to drive the correction wheel base 3 to move up and down, so as to adjust the contact position of the correction wheel 5 and the square tube. The correction wheel 5 is installed on the correction wheel base 3, and the axial direction of the correction wheel 5 is perpendicular to the axial direction of the guide rail 2, so as to correct the square tube in the vertical direction. The clamping mechanism 6 is composed of the sliding base 7, the upper clamping roller 8, the lower clamping roller 9, the sliding bearing seat 10 and the adjusting screw 11. The sliding base 7 is arranged on the fixed seat 1, and the bottom of the sliding base 7 is provided with sliding blocks 13 matched with the guide rails 2, the two side walls of the sliding base 7 are provided with sliding rails 14, and the top of the sliding base 7 is provided with two internal thread holes 12. The upper clamping roller 8 and the lower clamping roller 9 are both installed on the sliding base 7, and the two clamping rollers are arranged in parallel. The two ends of the lower clamping roller 9 are fixed to the sliding base 7, and the two ends of the upper clamping roller 8 are slidably connected to the sliding bearing seat 10. The sliding bearing seat 10 is provided with sliding strips matched with the sliding rails 14 around the sliding bearing seat 10, and the top of the sliding bearing seat 10 is provided with a through hole for connecting the adjusting screw 11. The adjusting screw 11 is connected to the sliding bearing seat 10 after penetrating through the internal thread hole 12. The rotation of the adjusting screw 11 can drive the upper clamping roller 8 to move along the sliding rail 14, so as to clamp the square tube.
[0031] In use, the square tube to be corrected is placed above the correction wheel 5 of the correction device. The correction wheel base 3 is driven to move up and down by the air cylinder 4, so as to adjust the position of the correction wheel 5. The position of the upper clamping roller 8 is adjusted by the adjusting screw 11, so that the upper clamping roller 8 and the lower clamping roller 9 clamp the square tube from the top and the bottom, and limit the movement of the square tube in the vertical direction. The air cylinder 4 is started, so that the correction wheel 5 corrects the square tube. After the correction is completed, the air cylinder 4 is turned off, the clamping mechanism 6 is loosened, and the square tube is taken out.
[0032] It should be pointed out that the limiting wheels 15 are installed on the side of the clamping mechanism 6, and the two limiting wheels 15 are arranged in parallel. The axial direction of the limiting wheel 15 is perpendicular to the axial direction of the upper clamping roller 8, so as to ensure that the limiting wheel 15 can contact the side of the square tube during the correction process, and limit the movement of the square tube in the horizontal direction. The axis of the limiting wheel 15 is hinged to the side wall of the sliding base 7 through the connecting rod 16. This design makes the limiting wheel 15 swing within a certain range, so as to adapt to the correction requirements of square tubes of different sizes. By adjusting the length or position of the connecting rod 16, the position where the limiting wheel 15 contacts the square tube can be adjusted, so as to ensure that the limiting wheel 15 can effectively limit the movement of the square tube during the correction process.
[0033] It is worth noting that the spring 17 is installed in the clamping mechanism 6, and its two ends are connected to the side wall of the connecting rod 16 and the sliding base 7 respectively. This design enables the spring 17 to provide additional clamping force when clamping the square tube, ensuring the stability of the square tube during the correction process. By adjusting the pre-tightening force of the spring 17, the clamping force of the clamping mechanism 6 on the square tube can be controlled. Proper pre-tightening force can ensure that the square tube does not slide or shift during the correction process, while avoiding excessive pressure on the square tube, which affects the correction effect. The addition of the spring 17 also helps to absorb the impact force that may occur during the correction process, reducing damage to the square tube and the correction device, and prolonging the service life of the equipment. When external force acts on the connecting rod 16, the connecting rod 16 will drive the spring 17 to compress or stretch, thereby realizing the relative movement between the connecting rod 16 and the sliding base 7, and maintaining the clamping of the square tube.
[0034] It should be noted that the hand wheel 18 is installed on the top of the adjusting screw 11, providing a manual operation interface. The hand wheel 18 is usually engaged with the threaded part of the adjusting screw 11, and by rotating the hand wheel 18, the rotation of the adjusting screw 11 can be directly driven. The operator can control the rotation of the adjusting screw 11 by rotating the hand wheel 18, thereby realizing the movement of the upper clamp roller 8 along the slide rail 14. This design makes the adjustment of the clamping mechanism 6 more intuitive and convenient, especially when fine adjustment of the position of the upper clamp roller 8 is required.
[0035] It is worth noting that the reference tube 19 is a straight tube, and its size and length are customized according to the size of the square tube to be corrected. The reference tube 19 can be inserted into the clamping mechanism 6 for pre-adjustment of the expected position of the square tube before actual correction. Before the square tube is placed into the correction device, the operator can insert the reference tube 19 into the clamping mechanism 6, and by adjusting the adjusting screw 11 and the hand wheel 18, the upper clamp roller 8 and the lower clamp roller 9 can accurately clamp the reference tube 19. This step helps to ensure the alignment accuracy of the clamping mechanism 6, reducing the number of adjustments during the actual correction process. The use of the reference tube 19 provides a method for quickly calibrating the clamping mechanism 6, ensuring accuracy and repeatability during the correction process. In addition, the reference tube 19 can also be used to detect and adjust the clamping force, avoiding excessive pressure on the square tube.
[0036] It should be noted that the reinforcing rib plate 20 is arranged inside the fixed seat 1 and connected to the two side walls of the fixed seat 1. The reinforcing rib plate 20 is usually made of strong materials such as steel or aluminum alloy to ensure that it has enough strength to support and reinforce the fixed seat 1. The main function of the reinforcing rib plate 20 is to enhance the structural stability of the fixed seat 1, preventing deformation of the fixed seat 1 due to the pushing force of the air cylinder 4 or other external forces during the correction process. The reinforcing rib plate 20 also improves the load-bearing capacity of the fixed seat 1, enabling it to withstand greater correction forces.
[0037] It is worth noting that the adjusting feet 21 are arranged at the bottom of the fixing base 1, which are used to adjust the levelness of the fixing base 1. The adjusting feet 21 can be rotatable screws or telescopic supports, which allow the operator to adjust the height and levelness of the fixing base 1 according to the actual situation of the ground. The main function of the adjusting feet 21 is to ensure that the fixing base 1 can remain horizontal on uneven ground, thereby ensuring the stability and correction accuracy of the entire square tube correction device.
[0038] It is worth noting that the limiting grooves 22 are arranged on the correction wheel 5, which are used to adapt to the square tube and limit its movement during the correction process. The limiting grooves 22 can be customized according to the size and shape of the square tube to ensure perfect matching with the square tube. The main function of the limiting grooves 22 is to position the square tube during the correction process, preventing the square tube from moving axially or circumferentially under the action of the correction force, thereby ensuring the accuracy and consistency of the correction.
[0039] Although the embodiments of the present application have been shown and described, it is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
