Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding technology, specifically to a fine-tuning device for steel welding. Background Technology
[0002] Steel welding is a process that uses welding technology to connect two separate steel components together.
[0003] In the process of steel welding, it is often necessary to lift a piece of steel horizontally and then weld other metal components to the top, bottom, or sides of the steel. Currently, a lifting platform is often used to lift and move the steel as a whole to adjust it to an appropriate height and position. However, it is difficult to fine-tune the position of the steel. For example, when the steel needs to be rotated circumferentially at a small angle, it is difficult to move due to its large weight. The error is also large when moving the steel as a whole using a lifting platform, which makes it inconvenient for workers to accurately connect the steel.
[0004] Therefore, in order to solve the above problems, a fine-tuning device for steel welding is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a fine-tuning device for steel welding, which can more flexibly adjust the position of steel based on lifting and moving, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fine-tuning device for steel welding, comprising a lifting platform vehicle, a box fixedly installed on the upper side of the platform of the lifting platform vehicle, a support plate provided inside the box, universal balls evenly installed on the upper side of the support plate, and a first through hole for aligning the universal balls opened at the top of the box; guide rods fixedly installed at the four corners inside the box, and guide holes for the guide rods to pass through the support plate; a pair of vertical plates fixedly installed on the lower side of the support plate, each vertical plate having an inclined guide groove; a pair of linear slide rails fixedly installed at the bottom inner side of the box, a common crossbeam slidably installed between the linear slide rails, guide wheels rotatably installed at both ends of the crossbeam, the guide wheels being located in the inclined guide grooves respectively; and an adjustment component for pushing and pulling the crossbeam is provided at the end of the box near the handrail of the lifting platform vehicle.
[0007] Specifically, the end of the inclined guide groove furthest from the adjustment component is higher than the end of the inclined guide groove closest to the adjustment component.
[0008] Optionally, when the lifting platform vehicle is a manually driven type, the adjusting component includes a screw and an internally threaded tube. The internally threaded tube is fixedly installed at one end of the box near the handrail of the lifting platform vehicle. The internally threaded tube is screwed to the screw. One end of the screw is rotatably assembled with the crossbeam, and the other end of the screw extends out of the box.
[0009] Furthermore, a handwheel is fixedly installed at one end of the screw that extends out of the box.
[0010] Optionally, when the lifting platform vehicle is electrically driven, the adjustment component includes an electric cylinder and a button. The electric cylinder is fixedly installed inside the box at one end near the handrail of the lifting platform vehicle. The output end of the electric cylinder is fixedly assembled with the crossbeam. The button is installed on the handrail of the lifting platform vehicle by a snap-fit.
[0011] Specifically, a linear bearing is fixedly installed inside the guide hole, and the guide rod is slidably assembled inside the linear bearing.
[0012] Specifically, a baffle is fixedly installed on the upper side of the box near the handrail of the lifting platform vehicle.
[0013] Specifically, an anti-slip pad is fixedly installed on the upper side of the box, and the anti-slip pad has a second through hole aligned with the first through hole.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] The adjustable components can push and pull the crossbeam on the linear slide rail, so that the guide wheel can move along the inside of the inclined guide groove, lift and lower the vertical plate to reset, and realize the lifting and lowering adjustment of the support plate. The adjustment is convenient and the operation is simple.
[0016] As the support plate is lifted, the omnidirectional ball joint of the box can support the steel placed on the upper side of the box. At this time, the position of the steel can be finely adjusted (translated, rotated) to facilitate alignment with other steel materials or to reach a predetermined position, thereby improving the efficiency of steel material movement and facilitating welding operations for workers.
[0017] In addition, the type of adjustment component can be matched and selected according to the drive type of the lifting platform vehicle, and its application range is wide. Attached Figure Description

Detailed Implementation
[0025] 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.
[0026] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a fine-tuning device for steel welding, including a lifting platform 12. The lifting platform 12 is an existing device. A box 1 is fixedly installed on the upper side of the platform of the lifting platform 12. The upper side of the box 1 is used to place the steel to be welded. A support plate 2 is provided inside the box 1. Universal balls 4 are evenly installed on the upper side of the support plate 2. A first through hole for aligning the universal balls 4 is opened on the top of the box 1. The universal balls 4 are existing components composed of a ball head and a base.
[0027] Guide rods 11 are fixedly installed at the four corners inside the box 1. The guide rods 11 are set vertically, and the support plate 2 has guide holes for the guide rods 11 to pass through. The setting of the guide rods 11 and the guide holes makes the support plate 2 only able to move up and down in the vertical direction.
[0028] A pair of vertical plates 7 are fixedly installed on the lower side of the support plate 2. Each vertical plate 7 has an inclined guide groove 13. A pair of linear slide rails 9 are fixedly installed on the bottom inner side of the box 1. A crossbeam 10 is slidably installed between the linear slide rails 9. Guide wheels 8 are rotatably installed at both ends of the crossbeam 10. The guide wheels 8 are located in the inclined guide grooves 13. An adjustment component 6 for pushing and pulling the crossbeam 10 is provided at one end of the box 1 near the handrail in the lifting platform vehicle 12. The crossbeam 10 can move left and right along the linear slide rails 9 with the guide wheels 8. The position of the crossbeam 10 can be adjusted by pushing and pulling it with the adjustment component 6, so that the guide wheels 8 can move along the inside of the inclined guide grooves 13, lifting and lowering the vertical plates 7 to achieve the lifting and lowering adjustment of the support plate 2.
[0029] Please see Figure 3The end of the inclined guide groove 13 away from the adjustment component 6 is higher than the end of the inclined guide groove 13 close to the adjustment component 6; so that when the guide wheel 8 moves to the left end of the linear slide rail 9, the support plate 2 falls and resets, and when the guide wheel 8 moves to the right end of the linear slide rail 9, the support plate 2 is lifted.
[0030] Depending on the type of the lifting platform vehicle 12, the adjustment component 6 can be used as an adapter:
[0031] For Form 1, please refer to Figure 2 and Figure 5 When the lifting platform vehicle 12 is a manually driven type, the adjusting component 6 includes a screw 61 and an internally threaded tube 62. The internally threaded tube 62 is fixedly installed at one end of the box 1 near the handrail in the lifting platform vehicle 12. The internally threaded tube 62 is horizontally set and located below the support plate 2. The screw 61 is screwed to the internally threaded tube 62. One end of the screw 61 is rotatably assembled with the crossbeam 10, and the other end of the screw 61 extends out of the box 1. When the screw 61 screwed to the internally threaded tube 62 is turned in the forward and reverse directions, the screw 61 will move to the left or to the right, thereby realizing the push-pull drive of the crossbeam 10.
[0032] In addition, to facilitate hand-tightening of the screw 61, a handwheel 63 is fixedly installed at one end of the screw 61 that extends out of the box 1, which serves to increase torque and save effort.
[0033] The manually driven lifting platform vehicle 12 is an existing device mainly composed of a movable base, scissor lift, hydraulic cylinder, foot pedal, pressure relief handle, handrail, and platform. The extension and retraction of the hydraulic cylinder can be controlled by the foot pedal and pressure relief handle, thereby changing the crossing angle of the scissor lift to adjust the height of the platform. The handrail and movable base facilitate the overall relocation.
[0034] For Form Two, please refer to [link / reference]. Figure 6 When the lifting platform vehicle 12 is electrically driven, the adjustment component 6 includes an electric cylinder 64 and a button 65. The electric cylinder 64 is fixedly installed inside the box 1 near the handrail of the lifting platform vehicle 12. The electric cylinder 64 is horizontally set and located below the support plate 2. The output end of the electric cylinder 64 is fixedly assembled with the crossbeam 10. The button 65 is installed on the handrail of the lifting platform vehicle 12 by a buckle. The electric cylinder 64 is electrically connected to the controller in the lifting platform vehicle 12 through the button 65. The button 65 can control the electric cylinder 64 to complete the push and pull drive of the crossbeam 10, which is more labor-saving and faster.
[0035] The difference between the electrically driven lifting platform truck 12 and the manually driven lifting platform truck 12 is that the electric lifting platform truck 12 uses a battery, controller, and hydraulic station to replace the foot pedal and pressure relief handle, making it easier to adjust the platform height.
[0036] Specifically, a linear bearing is fixedly installed inside the guide hole, and the guide rod 11 is slidably assembled inside the linear bearing; the linear bearing can prevent friction between the guide hole and the guide rod 11, thereby improving the accuracy and smoothness of the up-and-down movement of the support plate 2.
[0037] A baffle 5 is fixedly installed on the upper side of the box 1 near the handrail of the lifting platform vehicle 12. The baffle 5 can prevent the steel placed on the upper side from extending to the right side and intruding into the operating area of the handrail when it is being placed, thus serving as a limit and protection.
[0038] An anti-slip pad 3 is fixedly installed on the upper side of the box 1. The anti-slip pad 3 has a second through hole aligned with the first through hole. The anti-slip pad 3 is preferably made of rubber material to increase friction and prevent the placed steel from falling off.
[0039] The working principle of this embodiment:
[0040] First, the height of the platform is lowered by the lifting platform vehicle 12, and the box 1 is moved to the underside of the stored steel. Then, the height of the platform is raised, and the steel is lifted by the box 1 to facilitate the overall movement to the welding point. The steel is then adjusted to the required height by the lifting platform vehicle 12.
[0041] When precise docking or moving of steel plates is required, the support plate 2 is lifted by adjusting the components 6 and vertical plate 7, exposing the top of the universal ball 4 on the upper surface of the anti-slip pad 3 to support the steel. The steel can then be moved more easily and can be adjusted more flexibly (e.g., translation or rotation) to facilitate docking with other steel materials or to adjust to a suitable position. After adjustment, the vertical plate 7, support plate 2, and universal ball 4 are lowered and reset by adjusting the components 6 to reposition the steel, thereby facilitating welding operations.
[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
