Description

Technical Field

[0001] This utility model relates to the field of welding workbench technology, and more specifically, to a welding robot welding workbench for multiple workpieces. Background Technology

[0002] A multi-workpiece welding table for welding robots is a work platform specifically designed for welding robots to hold multiple workpieces to be welded. It can coordinate with the operation of the welding robot, fixing the workpieces at different positions and angles so that the welding robot can accurately perform welding operations on each workpiece.

[0003] To improve welding efficiency, common workbenches are equipped with multiple stations to hold multiple workpieces to be welded. Welding robots can perform welding operations on workpieces one by one to improve welding efficiency. However, workbenches do not have the ability to pre-process workpieces. If the workpieces are directly welded, the dust on the workpiece surface will affect the welding. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figures 1-5 In this utility model, a welding robot multi-workpiece welding workbench includes a base 1 with an I-shaped cross-section. A rotating ring 2 is rotatably connected to the base 1. A ring-shaped partition 3 is fixedly connected to the top of the rotating ring 2. A ring-shaped operating groove 4 is formed on the top of the rotating ring 2. A ring-shaped clamping mechanism 5 is also provided on the top of the rotating ring 2. A box 6 is inserted into and fixedly connected to the top of the base 1. An air pump 7 is installed on the top of the box 6, and the air outlet of the air pump 7 is connected to the box 6. Air outlet pipes 8 arranged at equal intervals are connected to the bottom of the box 6. A robotic arm 9 is fixedly connected to the top of the base 1, and a welding torch 10 is mounted on the robotic arm 9. The base 1 has a welding window 11 on its top, and a drive mechanism 12 for driving the rotating ring 2 to rotate is provided on the base 1. The drive mechanism 12 includes a motor 121, the top of which is embedded in the base 1. The bottom of the rotating ring 2 has an annular groove 122. The output shaft of the motor 121 passes through the base 1 and is fixedly connected to a gear 123. The inner wall of the annular groove 122 has a toothed groove that meshes with the gear 123. The clamping mechanism 5 includes two fixing blocks 501. The bottom of the two fixing blocks 501 is fixedly connected to the base 1. An electric push rod 502 is inserted through the two fixing blocks 501 and fixedly connected to them. One end of the two electric push rods 502 is fixedly connected to a clamping plate 503.

[0026] In this invention, during use, the rotating ring 2 serves as a worktable for placing workpieces. Multiple partitions 3 divide the rotating ring 2 into four workstations, each equipped with a clamping mechanism 5. Each workstation can hold one workpiece to be welded. After the workpiece is placed, the user activates the electric push rod 502, which moves two adjacent clamping plates 503 toward the workpiece until the clamping plates 503 are in close contact with the workpiece, thus achieving the effect of clamping the workpiece. Then, the user activates the motor 121, which drives the gear 123 to rotate. Since the gear 123 meshes with the tooth groove on the inner wall of the ring groove 122, the motor 121, when activated, drives the rotating ring 2 to rotate, which in turn moves the workpiece. Whenever a workpiece moves to the bottom of the air outlet pipe 8, the air pump 7 is turned on, drawing air into the box 6. The air is then sprayed from the air outlet pipe 8 onto the surface of the workpiece, blowing away the dust and cleaning it. After cleaning, the workpiece moves to the bottom of the welding window 11, and the user controls the robotic arm 9 to drive the welding torch 10 to weld it. After the welding is completed, the user turns on the motor 121 again to move the next workpiece to that position, allowing for welding of the remaining workpieces. This process allows for welding of multiple workpieces. The finished workpiece then moves to the back of the device, and the electric push rod 502 can be reversed to unlock it and remove the finished workpiece.

[0027] This device can simultaneously perform workpiece loading, unloading, cleaning, and welding, thereby effectively improving processing efficiency.

[0028] Please see Figures 1-4 The air pump 7 has an air inlet box 13 connected to its air inlet end, and a filter plate 14 is embedded in the air inlet box 13.

[0029] In this invention, when the air pump 7 draws in air through the air inlet, the air first enters the air inlet box 13 from the filter plate 14 and is then drawn into the air pump 7. During this process, the filter plate 14 filters the dust in the air, thereby effectively preventing the dust from causing secondary pollution to the workpiece.

[0030] Please see Figure 1 The air intake box 13 has an activated carbon layer 15 that is slidably connected to it, and a sealing plate 16 is fixedly connected to the base 1. The outer side of the sealing plate 16 is in contact with the rotating ring 2.

[0031] In this invention, the sealing plate 16 can seal the operating slot 4 of the work station below the welding torch 10. At this time, the exhaust gas generated by welding will only be discharged from the welding window 11. The air inlet box 13 is located on one side of the welding window 11, so the exhaust gas will be drawn into the air inlet box 13. The activated carbon layer 15 can filter the exhaust gas, thereby effectively preventing the exhaust gas generated by welding from polluting the working environment. Moreover, the exhaust gas generated by welding has a certain temperature. When the air with temperature is used to clean the workpiece, the air can have a preheating effect on the workpiece. When the preheated workpiece is welded, the welding stress and deformation are reduced, the crack generation is reduced, and the welding energy input requirement is reduced, thereby improving the practicality of the device.

[0032] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
