Technical Field

[0001] The utility model relates to the technical field of welding robots, in particular to an adjustable welding robot. Background Art

[0002] A welding robot is an automated device that is mainly used to perform welding tasks without manual operation. Welding robots are generally used in conjunction with welding equipment, such as arc welding or laser welding heads. Welding robots can work continuously, reducing the downtime in manual operation, and can perform efficient welding operations during the manufacturing process. Welding robots also reduce workers' exposure to dangerous environments, thereby improving workplace safety.

[0003] The welding robots currently on the market are generally installed by directly locking the base and the mounting seat of the welding robot through bolts when in use. The existing welding robots cannot be adjusted to assist in limiting according to actual conditions. Therefore, we propose improvements to the current adjustable welding robots.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the adjustable welding robot can assist in the installation of the welding robot through a limiting assembly jointly arranged between the base and the mounting seat, so that the welding robot has an adjustable mounting structure, and the power cord can be wound and limited through the cooperation between the winding drum and the limiting plate to prevent the power cord from dragging on the ground, so that the welding robot can easily reel in an excessively long power cord.

[0013] 1. The adjustable welding robot has a misaligned position between the limit sleeve and the fixed seat in the initial state. The staff pulls the limit pin downward to the limit position, then places the base above the mounting seat, and turns the handle to drive the connected threaded rod to rotate synchronously. With the rotation of the threaded rod, the connecting block and the limit sleeve can be synchronously moved to the limit position, and then the pulled limit pin is loosened. After the loosened limit pin is reset, it is docked and inserted into the inside of the limit slot. Finally, the corners of the base and the mounting seat are locked and installed by bolts. The welding robot can be assisted in installation by the limit assembly jointly arranged between the base and the mounting seat, so that the welding robot has an adjustable installation structure;

[0014] 2. For the adjustable welding robot, when the power cord of the welding robot is too long and drags on the ground, the connecting strip is pulled outward to the extreme position. At this time, there is no obstruction on both sides of the winding drum, so the power cord that is too long and drags on the ground can be wound inside the winding drum, and part of the power cord is reserved outside for normal use of the welding robot. After the winding is completed, the pulled connecting strip is loosened, and the limiting plates on the edges of both sides of the winding drum limit the wound power cord. Through the cooperation between the winding drum and the limiting plates, the power cord can be wound and limited to prevent the power cord from dragging on the ground, thereby making it convenient for the welding robot to wind up the excessively long power cord.

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

[0022] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a technical solution: an adjustable welding robot, comprising a welding robot body 1, a welding head 3 and a base 4, the upper end of the welding robot body 1 is connected to a connecting arm 2, and one end of the connecting arm 2 is connected to the welding head 3, a base 4 is arranged at the bottom of the welding robot body 1, and the base 4 is placed above the mounting seat 5, a limiting component 6 is arranged between the base 4 and the mounting seat 5, and the limiting component 6 comprises a limiting groove 61, a limiting sleeve 62, a connecting block 63, a fixing seat 64, a mounting groove 65, a threaded rod 66, a handle 67, a limiting pin 68 and a first spring 69, the limiting groove 61 is arranged at the lower edge of the mounting seat 5, the outer side of the mounting seat 5 is provided with a limiting sleeve 62, and the upper part of the limiting sleeve 62 is connected to a connecting block 63, and the two side edges of the base 4 are connected to the fixing seat 64.

[0023] A mounting groove 65 is provided inside the fixing seat 64, and the connecting block 63 is docked and inserted inside the mounting groove 65, and a threaded rod 66 is passed through the middle of the connecting block 63; the threaded rod 66 is connected to the inner wall of the mounting groove 65 through a bearing seat, and a handle 67 connected to the threaded rod 66 is installed on the outer side of the fixing seat 64, and a limiting pin 68 is passed through the lower part of the limiting sleeve 62; one end of the limiting pin 68 is docked inside the limiting groove 61, and a first spring 69 is passed through the middle of the limiting pin 68, and the two ends of the first spring 69 are respectively connected to the limiting pin 68 and the inner wall of the limiting sleeve 62, the cross-sectional size of the connecting block 63 matches the cross-sectional size of the mounting groove 65, the connecting block 63 and the threaded rod 66 are threadedly connected, and the limiting pin 68 forms a telescopic structure with the limiting sleeve 62 through the first spring 69.

[0024] During specific implementation, the limiting sleeve 62 and the fixing seat 64 are misaligned in the initial state, and the staff pulls the limiting pin 68 downward to the limit position. The pulled limiting pin 68 squeezes the first spring 69 sleeved on the outside, and then the base 4 is placed above the mounting seat 5 accordingly, and the handle 67 is turned to drive the connected threaded rod 66 to rotate synchronously. Since the threaded rod 66 and the connecting block 63 are threadedly connected, the connecting block 63 can move along the inside of the mounting groove 65 with the rotation of the threaded rod 66, and the moving connecting block 63 drives the connected limiting sleeve 62 to rotate synchronously. The limit sleeve 62 is then moved step by step until the limit sleeve 62 is adjusted to the limit position. At this time, the limit sleeve 62 is correspondingly sleeved on the outer edges of the base 4 and the mounting seat 5, and then the pulled limit pin 68 is loosened. The loosened limit pin 68 can automatically reset upward and dock with the inside of the limit groove 61 through the elastic force of the first spring 69. Finally, the corners of the base 4 and the mounting seat 5 are locked and installed by the bolts 7. The welding robot can be assisted in installation by the limit assembly 6 jointly arranged between the base 4 and the mounting seat 5, so that the welding robot has an adjustable installation structure.

[0026] During specific implementation, when the power cord of the welding robot is too long to drag on the ground, the connecting strip 12 is pulled outward, and the pulled connecting strip 12 drives the connected connecting pin 13 to move synchronously along the installation cavity 10, and the second spring 14 sleeved on the outside is squeezed by the moving connecting pin 13 until the moving connecting strip 12 drives the limiting plate 11 to move outward to the extreme position. At this time, there is no obstruction on both sides of the winding drum 8, so the power cord that is too long to drag on the ground can be wound around the inside of the winding drum 8, and part of the power cord is reserved outside for normal use of the welding robot. After the winding is completed, the pulled connecting strip 12 is loosened, and the loosened connecting strip 12 drives the limiting plate 11 and the connecting pin 13 to automatically reset inward to the initial position through the elastic force of the second spring 14. The limiting plates 11 on the edges of both sides of the winding drum 8 limit the wound power cord. Through the cooperation between the winding drum 8 and the limiting plates 11, the power cord can be wound and limited to prevent the power cord from dragging on the ground, thereby making it convenient for the welding robot to reel in the excessively long power cord.
