Description

A pairing station for angle steel components Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to an assembly station for angle steel components. Background Technology

[0002] Angle steel components are commonly used in the manufacture of engineering machinery and equipment, such as the standard fishplate sections of tower cranes. Angle steel components come in various structural forms, typically achieved by welding connecting plates and other connecting parts to angle steel or by machining grooves and holes. In processing angle steel components, the angle steel and connecting parts are usually first moved manually or with the aid of lifting equipment to a fixture for assembly and positioning. Then, a spot welding robot is used to perform spot welding, forming a preliminary connection between the angle steel and connecting parts to complete the assembly. Finally, full welding is performed to obtain the final product. In existing technologies, only one set of fixtures and one spot welding robot are used for assembling angle steel components. The assembly and unloading of one angle steel component must be completed before the assembly of the next component can begin, resulting in low production efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an assembly station for angle steel components that can greatly improve production efficiency.

[0004] The present invention adopts the following technical solution:

[0005] A welding station for angle steel components includes: a positioning device comprising a flipping seat and a flipping positioning machine that drives the flipping seat to flip; two sets of clamps disposed at both ends of the flipping seat and capable of rotating relative to the flipping seat; and a spot welding robot disposed at a preset workstation. The flipping positioning machine drives the flipping seat to rotate, causing the two sets of clamps to alternately move to a preset spot welding workstation and a preset loading workstation located away from the preset spot welding workstation. The positioning device drives the two sets of clamps to alternately move between the preset spot welding workstation and the preset loading workstation located away from the preset spot welding workstation. When any set of clamps is spot welding the spliced ​​and positioned angle steel component at the preset spot welding workstation by the spot welding robot, the other set of clamps is exactly at the preset loading workstation, which can realize simultaneous spot welding and splicing and positioning work, reduce equipment downtime, and greatly improve production efficiency.

[0006] As a preferred option, when one set of fixtures is located at the preset spot welding station, the other set of fixtures is located at the preset loading station. By clearly defining the alternating station layout of the two sets of fixtures, the seamless connection between the welding and loading processes is ensured, eliminating manual waiting time, realizing continuous production process, and maximizing equipment utilization.

[0007] Preferably, the spot welding robot is mounted on a mobile device, which drives the spot welding robot to adjust its welding position. This increases the welding coverage area, especially when the spot welding robot has a small arm span. It also reduces the possibility of interference and lowers the performance requirements for the spot welding robot.

[0008] Preferably, the mobile device includes a gantry, a drive mechanism located on the gantry, and a movable seat located on the drive mechanism. The gantry structure provides rigid support, and the combination of the drive mechanism and the movable seat achieves high-precision linear motion control, ensuring the smooth movement and repeatability of the robot and guaranteeing consistent welding quality.

[0009] Preferably, the displacement device includes two sets of oppositely arranged flipping seats and flipping displacement machines, with two sets of clamps located between the two sets of flipping seats and flipping displacement machines. The symmetrically arranged double flipping seats and flipping displacement machine structure reduces the risk of vibration and off-center load during the flipping process through mechanical balance design, enhances the overall stability of the system, and extends the service life of the equipment.

[0010] Preferably, the flipping seat is equipped with a drive motor for rotating the clamp.

[0011] Preferably, a pluggable positioning pin assembly is provided between the flipping seat and the flipping positioner to position and fix the angle of the flipping seat, preventing the flipping seat from flipping. This can avoid the large impact that would occur when placing heavy workpieces on the fixture at the preset loading station, thus affecting the spot welding operation at the preset spot welding station and the drive mechanism of the flipping positioner itself.

[0012] Preferably, it also includes multiple material storage mechanisms for storing materials.

[0013] Preferably, the system also includes a hoisting mechanism that hoists materials onto a fixture located at a pre-set loading station. This facilitates the storage and hoisting of materials used to assemble angle steel components and replacement parts of the fixture, thereby reducing manual labor intensity and improving assembly efficiency.

[0014] Preferably, the hoisting mechanism includes a hoisting device and a rotating device. The hoisting device is mounted on the rotating device, and the rotating device drives the hoisting device to rotate to reach any material storage mechanism, so as to hoist materials on any material storage mechanism to the clamp at the preset loading station.

[0015] Compared with the prior art, the present invention has the following advantages: The assembly station for angle steel components uses a displacement device to drive two sets of clamps to move alternately between a preset spot welding station and a preset loading station located far from the preset spot welding station. When any set of clamps is spot welding the spliced ​​and positioned angle steel component by the spot welding robot at the preset spot welding station, the other set of clamps is exactly at the preset loading station, which can realize the simultaneous spot welding and splicing positioning work, and can greatly improve production efficiency.

[0021] To facilitate understanding of the technical solution of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] As shown in Figures 1-4, a assembly station for angle steel components includes:

[0024] The displacement device 1 includes a flipping seat 1-1 and a flipping displacement machine 1-2 that drives the flipping seat 1-1 to flip.

[0025] Two sets of clamps 2 are set at both ends of the flip base 1-1 and can rotate relative to the flip base 1-1;

[0026] Spot welding robot 3 is set at a preset workstation;

[0027] The flipping and positioning machine 1-2 drives the flipping seat 1-1 to rotate, causing the two sets of clamps 2 to move alternately to the preset spot welding station and the preset loading station located far away from the preset spot welding station. The positioning device 1 drives the two sets of clamps 2 to move alternately between the preset spot welding station and the preset loading station located far away from the preset spot welding station. When any set of clamps 2 is spot welding the spliced ​​and positioned angle steel component by the spot welding robot 3 at the preset spot welding station, the other set of clamps 2 is exactly at the preset loading station. Spot welding and splicing and positioning work can be performed simultaneously, reducing equipment downtime and greatly improving production efficiency.

[0028] When one set of fixtures 2 is located at the preset spot welding station, the other set of fixtures 2 is located at the preset loading station. By clearly defining the alternating station layout of the two sets of fixtures, the seamless connection between welding and loading processes is ensured, eliminating manual waiting time, realizing continuous production process, and maximizing equipment utilization.

[0029] The spot welding robot 3 is mounted on the mobile device 4. The mobile device drives the spot welding robot to adjust the welding position, which can increase the welding coverage area. Especially when the arm span of the spot welding robot is small, it can reduce the possibility of interference and lower the performance requirements of the spot welding robot.

[0030] The mobile device 4 includes a gantry 4-1, a drive mechanism 4-2 located on the gantry 4-1, and a movable seat 4-3 located on the drive mechanism 4-2. The gantry structure provides rigid support, and the combination of the drive mechanism and the movable seat realizes high-precision linear motion control, ensuring the smooth movement and repeatability of the robot, and guaranteeing the consistency of welding quality.

[0031] The positioning device 1 includes two sets of opposing flipping seats 1-1 and flipping positioners 1-2. Two sets of clamps 2 are located between the two sets of flipping seats 1-1 and flipping positioners 1-2. The symmetrically arranged double flipping seats and flipping positioners structure reduces vibration and off-center load risks during the flipping process through mechanical balance design, enhances the overall stability of the system, and extends the service life of the equipment. The flipping movement of the flipping seats 1-1 allows the positions of the two sets of clamps 2 to be interchanged, thereby realizing the alternating movement of the two sets of clamps 2 at a preset spot welding station and a preset loading station located far from the preset spot welding station. The positioning device 1 has the advantages of compact structure and stable and reliable operation. The aforementioned flipping positioner 1-2 is a commercially available existing device.

[0032] The flipping base 1-1 is equipped with a drive motor that drives the clamp 2 to rotate. The clamp 2 is set on the flipping base 1-1 in a manner that allows it to rotate around a horizontal axis. The drive motor can position the clamp 2 at any rotation angle and adjust the rotation angle of the clamp 2 relative to the horizontal axis, so as to facilitate the adjustment of the clamp 2 to a suitable angle for splicing positioning operations and spot welding operations.

[0033] A pluggable positioning pin assembly 1-3 is provided between the flipping seat 1-1 and the flipping positioner 1-2 to fix the angle of the flipping seat and prevent it from flipping. This avoids the impact that could occur when placing heavy workpieces on the fixture at the preset loading position, thus preventing interference with the spot welding operation at the preset spot welding position and the drive mechanism of the flipping positioner itself. The aforementioned pluggable positioning pin assembly 1-3 is existing technology and includes two insertion holes on the flipping seat 1-1 and a movable pin on the frame of the flipping positioner 1-2. When one fixture 2 is at the preset spot welding position, the movable pin aligns with one of the insertion holes and inserts into it to prevent the flipping seat 1-1 from flipping; when the other fixture 2 is at the preset spot welding position, the movable pin aligns with the other insertion hole and inserts into it to prevent the flipping seat 1-1 from flipping. Furthermore, the movable pin can be a manually controlled pin or a pin driven by a motor, cylinder, etc.

[0034] It also includes multiple material storage mechanisms 5 for storing materials and a hoisting mechanism for hoisting materials to the clamps 2 located at the preset loading station, which facilitates the storage and hoisting of materials used to assemble angle steel components and the replacement parts of the clamps, thereby reducing the intensity of manual labor and improving the splicing efficiency.

[0035] The hoisting mechanism includes a hoisting device 6 and a rotating device 7. The hoisting device 6 is mounted on the rotating device 7, which drives the hoisting device 6 to rotate to reach any material storage mechanism 5, thus hoisting materials from any material storage mechanism to the clamp at a preset loading station. The preset loading station and multiple material storage mechanisms 5 are arranged at intervals around the vertical axis of the rotating device 7 and are within the hoisting working range of the hoisting device 6. By driving the hoisting device 6 to move around the vertical axis, materials from any material storage mechanism 5 can be hoisted to the clamp at the preset loading station, which has the advantages of compact structure and simple operation.

[0036] Preferably, in this embodiment, among the multiple material storage mechanisms 5, at least one material storage mechanism 5 is used to store the angle steel of the angle steel component, at least one material storage mechanism 5 is used to store small accessories such as iron blocks and plates of the angle steel component, and at least one material storage mechanism 5 is used to store the parts of the clamp 2. In other embodiments, the number of material storage mechanisms 5 can also be set according to actual needs.

[0037] The above are merely preferred embodiments of this utility model. The scope of protection of this utility model is defined by the scope of the claims. Any improvements and modifications made by those skilled in the art without departing from the spirit and scope of this utility model should also be considered as protection within the scope of this utility model.
