Description

Technical Field

[0001] This utility model relates to the field of straightening equipment, and in particular to a four-roller straightening device for straightening cross plate deformation. Background Technology

[0002] The cross plate consists of a single straight plate and two side plates. During the welding process, because the welding is done manually, the placement accuracy of the two side plates is not high. Therefore, after welding, problems such as misalignment, different angles, and skewness of the two side plates exist, affecting the use of the cross plate after welding. In order to ensure that the two side plates of the cross plate are in a parallel state after welding, we propose a four-roll straightening device for cross plate deformation correction. Utility Model Content

[0003] The purpose of this invention is to provide a four-roller straightening device for correcting cross plate deformation, which has the advantage of being able to correct cross plates.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a four-roller straightening device for cross-plate deformation straightening, comprising a fixed frame and four straightening rollers. Motor 1 and Motor 2 are mounted on the top of the fixed frame. Rotating rod 1 and Rotating rod 2 are rotatably connected inside the fixed frame via bearings. Rotating rod 3 and Rotating rod 4 are respectively mounted on the output ends of motor 1 and Motor 2 via couplings. A bevel gear 1 is fixedly connected to the surface of both rotating rod 1 and Rotating rod 2. The bevel gear 1 meshes with a bevel gear 2. Two connecting rods and a cylinder are fixedly connected to one side of the bevel gear 2. The surface of the bevel gear 2 is also rotatably connected to the fixed frame via bearings. The cylinder is fixedly sleeved inside the straightening rollers. Two linkage components are also provided inside the fixed frame.

[0005] By adopting the above technical solution, and by setting up motor one, motor two, rotating rod one, rotating rod two, rotating rod three, rotating rod four, bevel gear one, bevel gear two, connecting rod, cylinder, straightening roller and linkage assembly, the extrusion straightening and conveying of the welded cross plate can be realized.

[0006] The present invention is further configured such that: the two linkage components include two bevel gears three and two bevel gears four, the interiors of the two bevel gears four are respectively fixedly sleeved with rotating rod three and rotating rod four, the interiors of the two bevel gears three are each fixedly sleeved with a rotating rod, the two rotating rods are rotatably connected by bearings and a fixed frame, the surfaces of the two rotating rods are each fixedly sleeved with a first gear, the two first gears are each meshed with a second gear, and the interiors of the two second gears are respectively fixedly sleeved with rotating rod two and rotating rod one.

[0007] Using the above technical solution, by setting up two linkage components, the two linkage components are used to change the rotation direction of the second rotating rod and the first rotating rod, respectively.

[0008] The present invention is further configured such that: a connecting seat is sleeved on the surface of the cylinder, and two connecting grooves are opened inside the connecting seat to be slidably connected to the connecting rod.

[0009] By adopting the above technical solution, through the setting of the connecting seat and the connecting groove, when the bevel gear II drives the connecting rod to rotate, the connecting rod inside the connecting groove can pull the connecting seat, the straightening roller and the cylinder to rotate; and when the cylinder output end retracts, the cylinder pulls the straightening roller to move toward the bevel gear II, and the connecting groove can store the connecting rod.

[0010] The present invention is further configured such that: a fixed block is rotatably connected to the surface of the connecting seat via a bearing; a connecting plate is sleeved on the surface of the fixed block; two sliding grooves are formed on the inner wall of the connecting plate; and two sliders that are slidably connected to the sliding grooves are fixedly sleeved on the surface of the fixed block.

[0011] Using the above technical solution, the fixed block, connecting plate, slide groove and slider are set up. The fixed block is used to support the bearing inside. The slide groove is opened on the inner wall of the connecting plate. The slider slides inside the slide groove. When the cylinder output end retracts, it can pull the straightening roller, connecting seat, bearing and fixed block and slider to slide linearly inside the slide groove. When the bevel gear drives the connecting rod, connecting seat and straightening roller to rotate, the connecting seat can rotate inside the bearing and will not be restricted by the slider and slide groove to the point of being unable to rotate.

[0012] The present invention is further configured such that the side of the connecting seat near the straightening roller is fixedly connected to the straightening roller.

[0013] Using the above technical solution, the connecting seat and the straightening roller are fixedly connected. When the bevel gear rotates, it drives the connecting rod to rotate.

[0015] This invention uses two motors, one and two, to drive two straightening rollers to rotate. Four cylinders support the four straightening rollers. After the welded cross plate is placed between the four straightening rollers, the four cylinders push the four straightening rollers to forcibly straighten the tilted cross plate. Furthermore, driven by the two motors, the four straightening rollers can transport the cross plate. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1: Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A four-roller straightening device for correcting cross-plate deformation includes a fixed frame 1 and four straightening rollers 2. A motor 3 and a motor 4 are mounted on the top of the fixed frame 1. Inside the fixed frame 1, rotating rods 5 and 6 are rotatably connected via bearings. Rotating rods 7 and 8 are respectively mounted on the output ends of motors 3 and 4 via couplings. A bevel gear 9 is fixedly connected to the surface of both rotating rods 5 and 6. Bevel gear 9 meshes with a bevel gear 10. Two connecting rods 11 and a cylinder 12 are fixedly connected to one side of bevel gear 10. The surface of 0 is also rotatably connected to the fixed frame 1 via bearings, and the cylinder 12 is fixedly sleeved inside the straightening roller 2; the fixed frame 1 is also provided with two linkage components 15; by setting motor 3 and motor 4 to drive the two straightening rollers 2 to rotate respectively, and by setting four cylinders 12 to support the four straightening rollers 2, after the welded cross plate is placed between the four straightening rollers 2, the four cylinders 12 push the four straightening rollers 2 to forcibly straighten the inclined cross plate, and under the drive of motor 3 and motor 4, the four straightening rollers 2 can transport the cross plate.

[0024] Furthermore, the two linkage components 15 include two bevel gears 13 and two bevel gears 14. The interiors of the two bevel gears 14 are fixedly sleeved with rotating rods 7 and 8, respectively. The interiors of the two bevel gears 13 are fixedly sleeved with rotating rods 16. The two rotating rods 16 are rotatably connected by bearings and fixed frame 1. The surfaces of the two rotating rods 16 are fixedly sleeved with first gears 23. The two first gears 23 are meshed with second gears 24. The interiors of the two second gears 24 are fixedly sleeved with rotating rods 6 and 5, respectively. Through the setting of the linkage components 15, the number of linkage components 15 is two. The two linkage components 15 are used to change the rotation direction of rotating rods 6 and 5, respectively.

[0025] Furthermore, a connecting seat 17 is fitted onto the surface of the cylinder 12. The connecting seat 17 has two connecting grooves 18 that are slidably connected to the connecting rod 11. With the connection seat 17 and the connecting grooves 18, when the bevel gear 10 drives the connecting rod 11 to rotate, the connecting rod 11 can pull the connecting seat 17, the straightening roller 2 and the cylinder 12 to rotate inside the connecting grooves 18. When the output end of the cylinder 12 retracts, the cylinder 12 pulls the straightening roller 2 toward the bevel gear 10, and the connecting grooves 18 can accommodate the connecting rod 11.

[0026] Furthermore, a fixing block 19 is rotatably connected to the surface of the connecting seat 17 via a bearing. A connecting plate 20 is sleeved on the surface of the fixing block 19. Two sliding grooves 21 are opened on the inner wall of the connecting plate 20. Two sliders 22 that are slidably connected to the sliding grooves 21 are fixedly sleeved on the surface of the fixing block 19. Through the arrangement of the fixing block 19, the connecting plate 20, the sliding grooves 21 and the sliders 22, the fixing block 19 is used to support the bearing inside it. The sliding grooves 21 are opened on the inner wall of the connecting plate 20. The sliders 22 slide inside the sliding grooves 21, so that when the output end of the cylinder 12 retracts, it can pull the straightening roller 2, the connecting seat 17, the bearing, the fixing block 19 and the sliders 22 to slide linearly inside the sliding grooves 21. When the bevel gear 10 drives the connecting rod 11, the connecting seat 17 and the straightening roller 2 to rotate, the connecting seat 17 can rotate inside the bearing and will not be restricted by the sliders 22 and the sliding grooves 21 and will not be unable to rotate.

[0027] Furthermore, the side of the connecting seat 17 closest to the straightening roller 2 is fixedly connected to the straightening roller 2. Through the fixed connection between the connecting seat 17 and the straightening roller 2, when the bevel gear 10 rotates and drives the connecting rod 11 to rotate, the connecting rod 11 will drive the connecting seat 17 and the straightening roller 2 connected to the connecting seat 17 to rotate, so that the straightening roller 2 can be in a rotating state.

[0028] Brief description of the usage process: During use, the controller controls the four cylinders 12 to start, causing the output ends of the four cylinders 12 to retract. Since the bevel gear 10 is connected and positioned by the bearing and the fixed frame 1, it does not affect the rotation of the bevel gear 10. Therefore, when the output end of the cylinder 12 retracts, the end of the cylinder 12 that is close to the straightening roller 2 will pull the straightening roller 2 closer to the bevel gear 10.

[0029] The cylinder 12 pulls the four straightening rollers 2 away from each other, thereby increasing the distance between the four straightening rollers 2; then the worker puts the cross plate, which is tilted due to welding, between the four straightening rollers 2, and the controller controls the four cylinders 12 to push the straightening rollers 2 to reset and squeeze and straighten the cross plate.

[0030] To ensure that all the side plates of the cross plate are straightened, the cross plate needs to be transported.

[0031] During conveying, the controller starts motor 3 and motor 4.

[0032] The output terminals of both motor 3 and motor 4 rotate clockwise.

[0033] The output end of motor 13 rotates clockwise, causing the rotating rod 37, the bevel gear 19 on the surface of the rotating rod 37, and the bevel gear 414 on the surface of the rotating rod 37 to rotate clockwise. The bevel gear 19 on the surface of the rotating rod 37 drives the bevel gear 210 meshing with it to rotate counterclockwise. The counterclockwise rotation of bevel gear 210 causes the connecting rod 11, the connecting seat 17, and the straightening roller 2 connected to the connecting seat 17 to rotate counterclockwise.

[0034] The clockwise rotation of the bevel gear 14 on the surface of the rotating rod 3 7 drives the bevel gear 3 13 to rotate counterclockwise. The bevel gear 3 13 drives the first gear 23 and the rotating rod 16 to rotate counterclockwise. The counterclockwise rotation of the first gear 23 drives the second gear 24 meshing with it to rotate clockwise. The clockwise rotation of the second gear 24 drives the rotating rod 2 6 inside it to rotate clockwise. The rotating rod 2 6 drives the bevel gear 1 9 on its surface to rotate clockwise. The bevel gear 1 9 then drives the bevel gear 2 10 meshing with it to rotate the connecting rod 11, the connecting seat 17, and the straightening roller 2 counterclockwise.

[0035] The output end of motor 24 rotates clockwise, driving the rotating rod 48, the bevel gear 19 on the surface of the rotating rod 48, and the bevel gear 414 on the surface of the rotating rod 48 to rotate clockwise. The bevel gear 19 on the surface of the rotating rod 48 drives the bevel gear 210 meshing with it to rotate counterclockwise. The counterclockwise rotation of bevel gear 210 drives the connecting rod 11, the connecting seat 17, and the straightening roller 2 connected to the connecting seat 17 to rotate counterclockwise.

[0036] The clockwise rotation of the bevel gear 14 on the surface of the rotating rod 8 drives the bevel gear 13 to rotate counterclockwise. The bevel gear 13 drives the first gear 23 and the rotating rod 16 to rotate counterclockwise. The counterclockwise rotation of the first gear 23 drives the second gear 24 meshing with it to rotate clockwise. The clockwise rotation of the second gear 24 drives the rotating rod 5 inside it to rotate clockwise. The rotating rod 5 drives the bevel gear 9 on its surface to rotate clockwise. The bevel gear 9 then drives the bevel gear 10 meshing with it to drive the connecting rod 11, the connecting seat 17, and the straightening roller 2 to rotate counterclockwise.

[0037] The four straightening rollers 2 will rotate counterclockwise, and the four straightening rollers 2 can convey the cross plate.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
