Description

Technical Field

[0001] This invention relates to the field of building steel structure technology, specifically to an automatic welding equipment for square tube column components. Background Technology

[0002] Square tubular columns are important load-bearing components in steel structure buildings, mainly used as vertical support columns. See details for specific structures. Figure 1 As shown. A square tube column is generally composed of 4 square steel tube components and 3 node components, which are assembled and stacked in sequence and spot welded together to form a square tube column component. (Note: The square tube column component also includes rectangular tube column components.)

[0003] Currently, the traditional assembly and spot welding process for square tube column components is entirely manual. Workers move square tubes, lining plates, and partitions onto an assembly platform, manually position each component according to size and shape requirements, and then manually spot weld the weld seams of the assembled square tube column component using a welding torch, connecting the components to form the square tube column component to be welded. This process requires multiple employees to work together manually, resulting in low production efficiency, high labor costs, and inconsistent product quality. These drawbacks have become major bottlenecks in the production process. Summary of the Invention

[0004] To address the technical problems existing in the prior art, this invention provides an automatic assembly and welding equipment for square tube column components, which automates the assembly and spot welding of square tube column components, thereby improving product quality and production efficiency while significantly reducing the labor intensity of production personnel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic welding equipment for square tube column components, comprising a base, on which are arranged a plurality of spaced tube column support rollers, short tube column positioning and clamping devices and long tube column positioning and clamping devices, and longitudinal clamping devices movable along the base are provided at both ends of the base, and a movable welding robot device is provided on one side of the base.

[0006] The base of the workbench is a box-shaped structure made of welded steel plates. As a basic component, it supports and installs the column support rollers, short column positioning and clamping devices, and long column positioning and clamping devices to complete the assembly and spot welding of the square column components.

[0007] Longitudinal clamping device: Made of welded steel profiles, it is slidably connected to the base and realizes longitudinal positioning, clamping and moving to complete the assembly of each group of tube columns that make up the square tube column component.

[0008] An array of tube column support rollers is longitudinally segmented and evenly distributed on the base to support each tube column component (excluding short tube column components). Short tube column positioning and clamping devices are spaced apart between the tube column support rollers according to the number of short tube columns in the assembly. Long tube column positioning and clamping devices are located on the left and right sides of the short tube column positioning and clamping devices. During operation, one short tube column in the middle (with the side partitions assembled) is first positioned and clamped on the short tube column positioning and clamping device. Then, one end of the long tube column is placed on the tube column support roller and positioned and clamped by the long tube column positioning and clamping device. The longitudinal clamping devices at both ends are used to assemble it with the short tube column. Then, the welding robot moves to the corresponding position to weld. Multiple short tube columns and long tube columns are welded in sequence to form a square tube column component.

[0009] Furthermore, the short tube column positioning and clamping device includes a movable support seat mounted on the base. A support roller is mounted on the movable support seat. A positioning block and a clamping block are respectively mounted at both ends of the movable support seat. The bottom of the clamping block is slidably connected to the movable support seat, and a clamping cylinder is connected to the clamping block to drive its movement. The support roller is configured as two parallel rollers to support the short tube column. The movable support seat is connected to the base via a longitudinal guide rail pair. After completing the lateral positioning and clamping of the upper short tube column, it can also achieve longitudinal position adjustment and movement (which can be driven by a motor driving gears and racks), to meet the assembly requirements of square tube column components of different lengths between nodes.

[0010] Furthermore, a vertically arranged positioning roller is rotatably mounted on the positioning block to provide a positioning reference for the pre-assembled riser column component (short column). During the positioning and clamping process, the positioning roller contacts the short column to avoid friction and jamming caused by rigid contact.

[0011] Furthermore, the long tube column positioning and clamping device includes a fixed support base fixed between two adjacent tube column support rollers. Positioning block two and clamping block two are respectively provided at both ends of the fixed support base. The bottom of clamping block two is connected to the fixed support base via a roller assembly. A clamping cylinder two connected to clamping block two is provided inside the fixed support base. The long tube column positioning and clamping device is located at an appropriate position between the support rollers of the tube column. Driven by clamping cylinder two, the clamping blocks push each group of tube columns (excluding short tube columns) to move towards and clamp them to the positioning blocks, thus positioning and clamping the pre-assembled tube column components (excluding short tube columns). With the cooperation of the longitudinal clamping device, the sequential assembly of each group of square tube columns is completed.

[0012] Furthermore, two vertically arranged positioning rollers are rotatably mounted on the positioning block two. The positions of the positioning rollers two correspond to the support rollers of the two side columns, and the function of the positioning rollers two is the same as that of the positioning roller one.

[0013] Furthermore, the longitudinal clamping device includes a movable seat, the bottom of which is slidably connected to the base via a guide rail pair, and the movable seat is connected to a drive device that drives its reciprocating motion.

[0014] Furthermore, the driving device includes a drive motor mounted on one side of the movable base, the drive motor being connected to a gear set, and a rack structure meshing with the gear set being provided on one side of the base. The drive motor drives the gear set to rotate, and the gear set meshes with the rack of the base, thereby enabling the movable base to reciprocate along the base.

[0015] Furthermore, a clamping plate is provided on the inner side of the movable frame to clamp the column assembly.

[0016] Furthermore, the longitudinal clamping device is equipped with a distance measuring sensor, which, while clamping the tubing, works in conjunction with the servo system to detect the overall length of the assembled components.

[0017] Furthermore, the welding robot device includes a robot body, a welding device, and a displacement base device located on the side of the base. It is used to spot weld the connection points of the assembled square tube column workpiece according to the assembly sequence, forming the square tube column component. After sequentially positioning, clamping, and dimensionally inspecting the longitudinal and transverse directions of each feeding component, the welding robot device performs four-sided spot welding on the welds formed during assembly, ultimately constituting the assembled square tube column component.

[0018] The automatic welding equipment for square tube column components of the present invention solves the problems of low production efficiency, high labor intensity, and difficulty in guaranteeing quality in manual production. Compared with the prior art, the present invention has the following beneficial effects: 1. This automatic welding equipment uses an all-directional automatic positioning and clamping method for each component (one upper and one lower end pipe column, two long pipe columns and three short pipe columns) that make up the square pipe column component. This simplifies the tedious process of relying on manual positioning and improves assembly efficiency and assembly accuracy. 2. When assembling this automatic welding equipment, the middle short pipe column is used as the positioning component, which can shorten and balance the opposite movement distance of the longitudinal clamping devices on both sides during assembly, thereby improving the assembly efficiency of the components to a certain extent. 3. A distance sensor is installed on the clamping block of the longitudinal clamping device. In conjunction with the servo motor that drives the longitudinal clamping device, it can accurately detect the length of the square tube column assembly spot welded parts, eliminating tedious manual measurement work, saving time and improving measurement accuracy. 4. The traditional assembly process of square tube column components requires three employees to complete. However, by using automatic assembly and welding equipment for square tube column components, only one employee is needed to complete all the work, and the production efficiency can be increased by more than 1.5 times. 5. Using a welding robot to perform spot welding on the square tube column components can complete the spot welding of the four outer sides of the square tube column weld in one go, eliminating the need for the traditional manual spot welding process that requires the component to be turned 90 degrees.
