Technical Field
[0001] This utility model relates to the field of steel structure material welding technology, specifically a fixing device for welding steel structure materials. Background Technology
[0002] A steel structure welding fixing device is a specialized piece of equipment used to secure steel structure materials for welding operations. It clamps and positions the steel structure material, ensuring stability during welding and preventing movement or deformation. The use of this fixing device significantly improves welding precision and efficiency while ensuring the safety of the welding operation, making it an indispensable tool in steel structure welding work.
[0003] For example, Chinese Patent Application No. 202020067539.X discloses a fixing device for welding steel structure materials, including a base. A right-angle plate is provided on one side of the upper end of the base. The bottom end of the right-angle plate is welded to the upper side of the base. A fixing plate is provided at the corresponding position of the right-angle plate. The bottom end of the fixing plate is welded to the upper side of both sides of the base. A movable plate is provided between the right-angle plate and the fixing plate. A lead screw is provided on one side of the movable plate. The lead screw is embedded in the bearing. The bearing is welded to one side of the movable plate. A lead screw nut is sleeved on the outside of the lead screw. The lead screw and the lead screw nut are connected by a threaded rotation. The lead screw passes through the lead screw nut and extends out of the fixing plate. The lead screw nut is welded inside the fixing plate. This utility model uses the rotating lead screw to drive the movable plate to move. The movable plate and the right-angle plate clamp the components to be welded. The clamped components are very stable and do not easily shake during welding, which is very convenient and quick.
[0004] In the welding process of steel structure materials, the commonly used fixing device usually requires placing the steel pipe to be welded on it and fixing it by manually rotating multiple screws to squeeze it tightly. However, this method is cumbersome and inefficient.
[0005] Therefore, it is necessary to redesign and modify the fixing device for welding steel structure materials to effectively prevent the cumbersome and inefficient manual operation. Utility Model Content
[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a fixing device for welding steel structure materials, which has the advantages of being easy to use and solves the problems of cumbersome and inefficient manual operation.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for welding steel structure materials, comprising a base, a screw rod connected movably to the inner wall of the base via bearings, a pressure block threadedly connected to the surface of the screw rod, two steel pipes placed on the top of the base, and a pressing fixing mechanism, the pressing fixing mechanism comprising two slide rails fixedly connected to the top of the base, a slider slidably connected to the top of the slide rails, a support plate fixedly connected to the top of the slider, a screw rod connected movably to the inner wall of the support plate via bearings, a pressure plate threadedly connected to the surface of the screw rod, limit frames fixedly connected to both the left and right sides of the base, the limit frames restricting the left and right movement of the pressure plate, the screw rod driving the pressure plate downwards and pressing the top of the steel pipes, and a clutch drive mechanism provided on the top of the base.
[0008] As a preferred embodiment of this utility model, the clutch drive mechanism includes a dual-axis motor fixedly connected to the top of the base. A clutch gear is fixedly connected to the front output end of the dual-axis motor and the rear end of the first screw. An internal gear cylinder meshes with the surface of the rear clutch gear. When the internal gear cylinder moves forward, it meshes with the front clutch gear, thereby driving the first screw to rotate. This causes the first screw to drive the pressure block to press and fix the steel pipe. A bevel gear is fixedly connected to the rear output end of the dual-axis motor and the bottom of the second screw. The inner sides of the bevel gears mesh with each other. When the second screw drives the pressure plate upward, the bevel gears disengage, pushing the slider backward. The slider then drives the pressure plate to move backward synchronously, facilitating the placement of the steel pipe on the top of the base. A linkage mechanism is provided on the top of the base.
[0009] As a preferred embodiment of this utility model, the linkage mechanism includes a linkage plate movably connected to the surface of the inner gear cylinder via bearings. Rotating plates are contacted on both the left and right sides of the front of the linkage plate. A round rod is movably connected to the inner wall of the rotating plate via bearings. The bottom of the round rod is fixedly connected to the top of the base. Protrusions are fixedly connected to both the left and right sides of the inner wall of the pressure plate. The front of the protrusions contacts the outer side of the back of the rotating plate. When the pressure plate moves forward, it can drive the protrusions to press the rotating plate to flip backward, thereby pressing the linkage plate to move backward, causing the inner gear cylinder to disengage from the front clutch gear. An elastic component is provided on the top of the base.
[0010] As a preferred embodiment of this utility model, the elastic component includes sliding plates fixedly connected to the left and right sides of the linkage plate. The bottom of the sliding plate extends into the interior of the base. The sliding plate can slide backward inside the base. A spring is fixedly connected to the back of each sliding plate. A fixing plate is fixedly connected to the rear end of each spring. The bottom of the fixing plate is fixedly connected to the top of the base. The spring can press the linkage plate to move forward, so that the internal gear cylinder meshes with the two clutch gears simultaneously.
[0011] As a preferred embodiment of this invention, a handle is fixedly connected to the back of the slider, and the handle can conveniently drive the slider to move back and forth.
[0012] As a preferred embodiment of this utility model, the inner wall of the pressure plate is slidably connected to a limiting frame, and the inner side of the limiting frame is fixedly connected to the left and right sides of the base. The limiting frame can restrict the forward and backward movement of the pressure plate, prevent it from swaying left and right, and make it more stable during movement.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. When this utility model is used, under the action of the extrusion fixing mechanism, clutch drive mechanism, linkage mechanism and elastic component, the steel pipe can be quickly extruded, fixed and released, avoiding the inefficiency caused by the need to manually turn multiple screws for extrusion fixing in traditional steel pipe fixing devices, thus giving it the advantage of being easy to use.
[0015] 2. This utility model achieves independent control of screw one and screw two by setting up a clutch drive mechanism. This improves the ease of operation and automation of the device, and reduces the complexity of manual operation. Attached Figure Description

[0022] 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.
[0023] like Figures 1 to 5 As shown, the present invention provides a fixing device for welding steel structure materials, including a base 1, a screw 2 movably connected to the inner wall of the base 1 via a bearing, a pressure block 3 threadedly connected to the surface of the screw 2, two steel pipes 4 placed on the top of the base 1, and a pressing fixing mechanism. The pressing fixing mechanism includes two slide rails 5 fixedly connected to the top of the base 1, a slider 6 slidably connected to the top of the slide rails 5, a support plate 7 fixedly connected to the top of the slider 6, a screw 8 movably connected to the inner wall of the support plate 7 via a bearing, a pressure plate 9 threadedly connected to the surface of the screw 8, and limit frames 10 fixedly connected to both the left and right sides of the base 1. The limit frames 10 can restrict the left and right movement of the pressure plate 9. The screw 8 can drive the pressure plate 9 to move downward and press and fix the top of the steel pipes 4. A clutch drive mechanism is provided on the top of the base 1.
[0024] refer to Figure 3 The clutch drive mechanism includes a dual-axis motor 11 fixedly connected to the top of the base 1. The front output end of the dual-axis motor 11 and the rear end of the screw 1 2 are both fixedly connected to a clutch gear 12. The surface of the rear clutch gear 12 is meshed with an internal gear cylinder 13. When the internal gear cylinder 13 moves forward, it can mesh with the front clutch gear 12, thereby driving the screw 1 2 to rotate. The screw 1 2 drives the pressure block 3 to press and fix the steel pipe 4. The rear output end of the dual-axis motor 11 and the bottom of the screw 2 8 are both fixedly connected to bevel gears 14. The inner sides of the bevel gears 14 mesh with each other. When the screw 2 8 drives the pressure plate 9 to move upward, the bevel gears 14 disengage and push the slider 6 to slide backward. The slider 6 drives the pressure plate 9 to move backward synchronously, thereby facilitating the placement of the steel pipe 4 on the top of the base 1. The top of the base 1 is provided with a linkage mechanism.
[0025] As a technical optimization of this utility model, a clutch drive mechanism is set up to achieve independent control of screw 2 and screw 8. This improves the ease of operation and automation of the device, and reduces the complexity of manual operation.
[0026] refer to Figure 4The linkage mechanism includes a linkage plate 15 movably connected to the surface of the inner gear cylinder 13 via bearings. The left and right sides of the front of the linkage plate 15 are in contact with rotating plates 16. The inner wall of the rotating plate 16 is movably connected to a round rod 17 via bearings. The bottom of the round rod 17 is fixedly connected to the top of the base 1. The left and right sides of the inner wall of the pressure plate 9 are fixedly connected to protrusions 18. The front of the protrusions 18 is in contact with the outer side of the back of the rotating plate 16. When the pressure plate 9 moves forward, it can drive the protrusions 18 to squeeze the rotating plate 16 to flip backward, thereby squeezing the linkage plate 15 to move backward, so that the inner gear cylinder 13 disengages from the front clutch gear 12. The top of the base 1 is provided with an elastic component.
[0027] As a technical optimization of this utility model, a linkage mechanism is set up to achieve automatic control of the meshing state between the internal gear cylinder 13 and the front clutch gear 12. This improves the safety and reliability of the device and ensures the coordinated operation of the various components of the device.
[0028] refer to Figure 3 The elastic component includes sliding plates 19 fixedly connected to the left and right sides of the linkage plate 15. The bottom of the sliding plate 19 extends into the interior of the base 1. The sliding plate 19 can slide backward inside the base 1. Springs 20 are fixedly connected to the back of the sliding plate 19. A fixing plate 21 is fixedly connected to the rear end of the spring 20. The bottom of the fixing plate 21 is fixedly connected to the top of the base 1. The springs 20 can press the linkage plate 15 to move forward, so that the internal gear cylinder 13 meshes with the two clutch gears 12 at the same time.
[0029] As a technical optimization of this utility model, by setting up elastic components, the operation process is simplified, the working efficiency of the device is improved, and the device can work continuously and stably.
[0030] refer to Figure 2 A handle 22 is fixedly connected to the back of the slider 6, which can easily move the slider 6 back and forth.
[0031] As a technical optimization of this utility model, by setting a handle 22, the operator can easily move the slider 6 back and forth. This improves the ease of operation of the device, reduces the labor intensity of the operator, and can significantly improve work efficiency, especially in work scenarios that require frequent placement and removal of steel pipes 4.
[0032] refer to Figure 4 The inner wall of the pressure plate 9 is slidably connected to the limit frame 23. The inner side of the limit frame 23 is fixedly connected to the left and right sides of the base 1. The limit frame 23 can restrict the forward and backward movement of the pressure plate 9, prevent it from swaying left and right, and make it more stable during movement.
[0033] As a technical optimization of this utility model, by setting the pressure plate 9, the stability of the pressure plate 9 during the movement is improved, ensuring the accuracy and stability of the pressure plate 9 in squeezing the steel pipe 4, thereby improving the fixing effect of the steel pipe 4 and reducing the problem of the steel pipe 4 not being firmly fixed due to the shaking of the pressure plate 9.
[0034] The working principle and usage process of this utility model: This device is mainly used to compress and fix two steel pipes 4 placed on top of the base 1. In the initial state, the slider 6 is located at the front end of the slide rail 5, the pressure plate 9 is in a higher position, the internal gear cylinder 13 is engaged with the rear clutch gear 12 and disengaged from the front clutch gear 12, and the bevel gears 14 are engaged with each other; when placing the steel pipes 4, the operator pushes the slider 6 backward through the handle 22, and the slider 6 drives the support plate 7 and the pressure plate 9 to move backward synchronously to make room, and then the two steel pipes 4 are placed on top of the base 1; when compressing and fixing the steel pipes 4, the dual-axis motor 11 is started, and the front output end drives the front clutch gear 12 to rotate, and the internal gear cylinder 13 rotates accordingly. When it is necessary to rotate the screw 2, pull the handle 22 backward, so that the handle 22 moves the slider 6 and the pressure plate 9 backward to the limit position (at this time, the bevel gears 14 disengage). At this time, the spring 20 squeezes the sliding plate 19, so that the linkage plate 15 drives the internal gear cylinder 13 to move forward and mesh with the front clutch gear 12 (at this time, the two clutch gears 12 and the internal gear cylinder 13 are in a synchronous meshing state), which in turn drives the screw 2 to rotate. The pressure block 3 on the surface of the screw 2 then moves forward, thereby squeezing and fixing the parallel position of the steel pipe 4. At this point, manually pushing handle 22 causes slider 6 to slide forward, which in turn moves pressure plate 9 forward synchronously. This causes protrusion 18 to press and rotate plate 16 backward, and press linkage plate 15 to move backward, causing internal gear cylinder 13 to disengage from front clutch gear 12 (at this time, bevel gears 14 are meshed with each other). Then, the dual-axis motor 11 drives bevel gear 14 to rotate, which in turn drives screw 8 to rotate. The rotation of screw 8 causes pressure plate 9 to move downward and press and fix the top of steel pipe 4. The overall structure seems complex, but the only steps required are starting and stopping the dual-axis motor 11 and pushing handle 22 forward and backward. With practice, steel pipe 4 can be quickly clamped and fixed. This avoids the inefficiency of traditional steel pipe fixing devices that require manually turning multiple screws for pressing and fixing, making it easy to use.
[0035] In summary, when this utility model is used, under the action of the compression fixing mechanism, clutch drive mechanism, linkage mechanism and elastic component, the steel pipe 4 can be quickly compressed, fixed and released, avoiding the inefficiency caused by the traditional steel pipe 4 fixing device requiring manual tightening of multiple screws for compression fixing, thus giving it the advantage of being easy to use.
