Description

Technical Field

[0001] The utility model relates to the technical field of welding robots, in particular to an auxiliary device of a 9-axis cantilever welding robot. Background Art

[0002] Industrial robots are the most mature and successful robotic technology currently in use. They can replace manual labor to perform high-intensity and complex repetitive labor, improve production efficiency and product quality, and liberate workers from complex and high-intensity labor environments to perform more intelligent and low-intensity work. Welding robots are an important branch of the industrial robot field.

[0003] The 9-axis cantilever welding robot is a type of welding robot. When the welding robot is in use, an auxiliary fixing device is usually used to fix the welding robot. However, most of the auxiliary devices cannot adjust the overall height and angle after being fixed, which is a bit inconvenient. Therefore, an auxiliary device for the 9-axis cantilever welding robot is proposed to solve the above problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides an auxiliary device for a 9-axis cantilever welding robot, which has the advantages of adjustable height and angle, and solves the problem that the height and angle of the welding robot cannot be adjusted.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: an auxiliary device for a 9-axis cantilever welding robot, comprising a base, a drive motor fixed to the top of the base, a stabilizing frame fixed to the top of the base, a threaded telescopic rod penetrating the stabilizing frame fixed to the output shaft of the drive motor, the threaded telescopic rod being rotatably connected to the stabilizing frame;

[0006] A fixing block is fixed on the top of the threaded telescopic rod, an electric fan is fixed inside the fixing block, a mounting plate is fixed on the top of the fixing block, and two adjustment components are provided at the bottom of the fixing block, and the adjustment components are used to adjust the movement of the mounting plate;

[0007] The adjustment assembly includes an adjustment rod, an adjustment block, a limit block and a limit rod. The bottom of the fixed block is fixed to the adjustment rod, the outer surface of the adjustment rod is slidably connected to the adjustment block that is slidably connected to the base, the top of the base is fixed to the limit block, and the inside of the limit block is threadedly connected to the limit rod inserted into the adjustment block.

[0008] Furthermore, the threaded telescopic rod includes an extension block fixed to the output shaft of the driving motor, and the top of the extension block is threadedly connected to the extension rod fixed to the fixed block.

[0009] Furthermore, a through hole is provided inside the stabilizing frame, a stabilizing bearing is fixed inside the through hole, and the interior of the stabilizing bearing is fixed to the extension block.

[0010] Furthermore, a threaded strip is fixed on the outer surface of the limiting rod, and a threaded hole adapted to the threaded strip is opened inside the limiting block.

[0011] Furthermore, sliding blocks are fixed on both the left and right sides of the adjusting rod, and a sliding groove is provided inside the adjusting block to be slidably connected to the sliding block.

[0012] Furthermore, a connecting block slidably connected to the base is fixed to the bottom of the adjusting block, and a connecting block slidably connected to the base is fixed to the bottom of the connecting block.

[0013] Furthermore, a roller is rotatably connected to the bottom of the connecting block, and an anti-slip pad is fixed to the bottom of the base.

[0015] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0016] The auxiliary device of the 9-axis cantilever welding robot can start the driving motor to make the threaded telescopic rod, which is restricted in rotation by the fixed block, move due to the extrusion of the thread, thereby completing the adjustment of the height of the mounting plate. By rotating the limit rod inside the adjustment component, the adjustment component can lose its fixation on the fixed block. At this time, starting the driving motor can make the fixed block rotate together, thereby completing the adjustment of the angle of the mounting plate, making the overall operation more practical.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 In this embodiment, an auxiliary device of a 9-axis cantilever welding robot includes a base 1, which is provided to support the whole body. A driving motor 2 is fixed to the top of the base 1, and a stabilizing frame 3 is fixed to the top of the base 1. The output shaft of the driving motor 2 is fixed with a threaded telescopic rod 4 that passes through the stabilizing frame 3. The threaded telescopic rod 4 is rotatably connected to the stabilizing frame 3. A through hole is opened inside the stabilizing frame 3, and a stabilizing bearing is fixed in the through hole. The inside of the stabilizing bearing is fixed to the extension block. By setting the stabilizing bearing, the stability of the rotation of the extension block can be effectively improved, thereby making the whole body more stable.

[0023] In addition, a fixed block 5 is fixed to the top of the threaded telescopic rod 4, and the threaded telescopic rod 4 includes an extension block fixed to the output shaft of the drive motor 2. The top of the extension block is threadedly connected to the extension rod fixed to the fixed block 5. An electric fan 6 is fixed inside the fixed block 5. The electric fan 6 can effectively increase the air flow rate, thereby cooling the welding robot. A mounting plate 7 is fixed to the top of the fixed block 5, and two adjustment components 8 are provided at the bottom of the fixed block 5. The adjustment component 8 is used to adjust the movement mode of the mounting plate 7.

[0024] In general, since the adjustment assembly 8 limits the rotation of the fixed block 5 and the extension rod, when the drive motor 2 rotates, the entire threaded telescopic rod 4 is adjusted in length due to the squeezing of the threads.

[0025] See also Figures 2 to 3 The adjustment assembly 8 in this embodiment includes an adjustment rod 801, an adjustment block 802, a limit block 803 and a limit rod 804. The bottom of the fixed block 5 is fixed to the adjustment rod 801. The outer surface of the adjustment rod 801 is slidably connected to the adjustment block 802 which is slidably connected to the base 1. Sliding blocks are fixed on both sides of the adjustment rod 801. The interior of the adjustment block 802 is provided with a sliding groove which is slidably connected to the sliding block. By setting the sliding block and the sliding groove, the sliding of the adjustment block 802 can be made more stable. The adjustment rod 801 and the adjustment block 802 are slidingly connected with large friction, and a large force is required to pull them.

[0026] Furthermore, a connecting block 805 that is slidably connected to the base 1 is fixed to the bottom of the adjusting block 802, and a connecting block 806 that is slidably connected to the base 1 is fixed to the bottom of the connecting block 805. By setting the connecting block 805 and the connecting block 806, the adjusting block 802 can be effectively prevented from separating from the base 1. The bottom of the connecting block 806 is rotatably connected to the roller 807. By setting the roller 807, the friction between the adjusting component 8 as a whole and the base 1 can be effectively reduced.

[0027] In addition, a non-slip pad is fixed to the bottom of the base 1, the top of the base 1 is fixed to the limit block 803, the interior of the limit block 803 is threadedly connected to the limit rod 804 inserted into the adjustment block 802, and the two limit rods 804 are fixed on the opposite sides of each other with control blocks, the outer surface of the control block is fixed with a friction strip, the outer surface of the limit rod 804 is fixed with a threaded strip, and the interior of the limit block 803 is provided with a threaded hole that is compatible with the threaded strip. Through the threaded connection, the limit rod 804 will move simultaneously when it rotates.

[0028] In general, by rotating the limit rod 804, the limit rod 804 can be moved to the side away from the adjustment block 802, thereby causing the limit rod 804 and the adjustment block 802 to lose their connection, so that the adjustment block 802 can rotate, and when the threaded telescopic rod 4 rotates, the fixed block 5 will rotate together.

[0029] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0030] The working principle of the above embodiment is:

[0031] When the driving motor 2 is started, the limit rod 804 limits the rotation of the adjusting block 802 and the adjusting rod 801, thereby limiting the rotation of the fixing block 5 fixed to the adjusting rod 801. When the driving motor 2 pushes the threaded telescopic rod 4 to rotate, the fixing block 5 and the extension rod cannot rotate, so that the extension rod will move due to the extrusion of the thread, thereby completing the height adjustment of the fixing block 5 and the mounting plate 7. After the height adjustment is completed, by rotating the limit rod 804, the limit rod 804 can be moved to the side away from the adjusting block 802 due to the extrusion of the thread, thereby causing the limit rod 804 to lose the connection with the adjusting block 802. At this time, the driving motor 2 is started, and the extension rod can drive the fixing block 5, the adjusting block 802 and the adjusting rod 801 to rotate, so that the fixing block 5 and the mounting plate 7 rotate to complete the angle adjustment. The overall structure is simple, and the overall height and angle are adjustable, which makes the overall structure more practical.
