DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Example 1, reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, and provides a dual arc welding robot workstation, which can facilitate the movement of the second arc welding robot 102, or cooperate with the first arc welding robot 101 to achieve the effect of dual arc welding, and includes a support component 100, including a first arc welding robot 101 and a second arc welding robot 102, a workbench 103 arranged at the lower ends of the first arc welding robot 101 and the second arc welding robot 102, a track 104 arranged on the workbench 103, and a guide groove 105 arranged at the lower end of the second arc welding robot 102; a slide The moving component 200 includes a rolling component 201 arranged at the lower end of the second arc welding robot 102, a limiting component 202 arranged on the rolling component 201, a pushing component 203 arranged on the limiting component 202, a transmission component 204 arranged on the pushing component 203, and a power component 205 arranged on the track 104; the fixing component 300 includes an anti-loosening component 301 arranged on the track 104, a pumping component 302 arranged on the rolling component 201, and an elastic component 303 arranged on the pumping component 302.

[0026] Specifically, the first arc welding robot 101 and the second arc welding robot 102 cooperate to weld the front and back sides of the workpiece at the same time, so that the welding effect is better. The first arc welding robot 101 and the second arc welding robot 102 are combined with the workbench 103 to form a double arc welding workstation. When welding, the first arc welding robot 101 and the second arc welding robot 102 can both move at multiple angles to facilitate welding. This is the prior art and will not be elaborated here.

[0027] Furthermore, the rolling component 201 includes a base 201a arranged at the lower end of the second arc welding robot 102, and four mounting grooves 201b are provided on the base 201a. A lifting block 201c is slidably connected in the mounting groove 201b, and the lifting block 201c is elastically connected to the inner wall of the mounting groove 201b through a first spring 201d. The lifting block 201c is rotatably connected to a mounting frame 201e, and a roller 201f is rotatably connected to the mounting frame 201e; the mounting groove 201b and the lifting block 201c are both T-shaped, and the horizontal width of the mounting groove 201b is greater than the horizontal width of the lifting block 201c; the limiting component 202 includes two mounting cavities 202a arranged on the base 201a, and two plug blocks 202b cooperating with the lifting block 201c are slidably connected in the two mounting cavities 202a.

[0028] Among them, the second arc welding robot 102 and the first arc welding robot 101 are both provided with a base 201a at the lower end, and a threaded hole is set on the base 201a so as to fix the second arc welding robot 102 or the first arc welding robot 101 on the workbench 103. It should be noted that the positions of the second arc welding robot 102 and the first arc welding robot 101 can be swapped and adjusted as needed. The horizontal width of the mounting groove 201b is greater than the horizontal width of the lifting block 201c, so that the lifting block 201c can slide up and down in the mounting groove 201b to avoid the lifting block 201c from getting stuck.

[0029] Preferably, the pushing assembly 203 includes an installation opening 203a that passes through the installation cavity 202a, a wedge block 203b is slidably connected in the installation opening 203a, a support block 203c is fixedly connected to the wedge block 203b, the support block 203c is elastically connected to the inner wall of the installation cavity 202a through a second spring 203d, a through opening 203e is provided on the support block 203c and the plug block 202b, a transmission plate 203f is rotatably connected in the through opening 203e of the support block 203c through a rotating shaft, and the transmission plate 203f is rotatably connected to the inner wall of the through opening 203e on the plug block 202b through a transmission shaft; the transmission assembly 204 includes a slope 204a fixedly connected to the workbench 103, and a long strip block 204a is fixedly connected to the slope 204a 04b, the upper end surface of the long block 204b is flush with the upper end surface of the slope 204a, and the upper end surfaces of the slope 204a and the long block 204b are extended to the upper side of the track 104, the long block 204b and the slope 204a are between the front and rear rollers 201f, and there are gaps between the long block 204b, the slope 204a and the front and rear rollers 201f; the power component 205 includes an electric slide rail arranged on the track 104, and the electric slide rail is provided with two horizontal slides 205a and one inclined slide 205b, the right end of the horizontal slide 205a is open, and the left end of the second arc welding robot 102 is fixedly connected to a transfer plate 205c, and the transfer plate 205c is fixedly connected to a guide column 205d that cooperates with the electric slide rail.

[0030] It should be noted that the slope 204a here cooperates with the oblique side of the wedge block 203b to avoid the wedge block 203b and the slope 204a from being stuck. The long block 204b and the slope 204a are located between the front and rear rollers 201f, so that when the second arc welding robot 102 moves, the roller 201f will not slide onto the slope 204a. There are gaps between the long block 204b, the slope 204a and the front and rear rollers 201f to avoid the roller 201f from being stuck with the front and rear side walls of the slope 204a.

[0031] When in use, in the initial state, the roller 201f is in contact with the ground, which facilitates the direct movement of the second arc welding robot 102. At the same time, the upper end surface of the workbench 103 on which the plug 202b is stuck is flush with the ground, so that the second arc welding robot 102 can move onto the workbench 103. When the first arc welding robot 101 and the second arc welding robot 102 need to be used in conjunction with each other, it is only necessary to match the guide column 205d on the base 201a of the second arc welding robot 102 with the horizontal slide 205a of the electric slide rail, and then start the electric slide rail to drive the guide column 205d on the horizontal slide rail. 205a slides in the guide groove 105, so that the guide groove 105 moves to the upper side of the track 104, and then the electric slide rail drives the guide column 205d to slide. At this time, the wedge block 203b contacts the bevel, so that the wedge block 203b moves upward, and the support block 203c moves upward. When the support block 203c moves upward, the second spring 203d is compressed, driving the transmission plate 203f to move upward, so that the insertion block 202b moves toward the support block 203c, and the insertion block 202b is separated from the lifting block 201c. At this time, the lifting block 201c can move upward, and then move to the electric slide rail along with the guide column 205d. When the second arc welding robot 102 moves downward, the roller 201f moves upward, the lifting block 201c moves upward, and the first spring 201d is compressed (here, the elasticity of the plurality of first springs 201d is sufficient). The lifting block 201c is large enough to support the weight of the second arc welding robot 102, and the roller 201f is stored. When the upper end surface of the lifting block 201c moves to the upper side of the plug block 202b, the wedge block 203b is separated from the long strip block 204b. At this time, although the support block 203c is reset under the action of the second spring 203d, the transmission reset drives the plug plate to reset, but the plug block 202b cannot be reset because the side wall of the lifting block 201c is against the plug block 202b. At this time, the wedge block 203b is still on the upper side of the long strip block 204b, which facilitates the wedge block 203b to return to the right side of the slope 204a.

[0032] When the roller 201f is completely stored in the installation groove 201b, the inner top of the guide groove 105 is against the track 104. At this time, the second arc welding robot 102 will not move forward and backward, and is restricted by the electric slide rails in the up, down, left and right directions and cannot move, thereby achieving the fixation of the second arc welding robot 102 so that the second arc welding robot 102 can cooperate with the first arc welding robot 101 for welding. It is worth noting that the thickness of the lifting block 201c here is sufficient. During the upward movement of the lifting block 201c, the insert block 202b is always against the side wall of the lifting block 201c.

[0033] In summary, by setting the sliding component 200, when the second arc welding robot 102 moves, the roller 201f assists the second arc welding robot 102 to move, and when the second arc welding robot 102 cooperates with the first arc welding robot 101, the roller 201f can be stored in the installation groove 201b to prevent the second arc welding robot 102 from sliding, making it convenient for combination and separation, and facilitating production line adjustment.

[0034] Example 2, reference Figure 1 to Figure 6 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an anti-loosening component 301 of a dual arc welding robot workstation, which solves the problem of how to further prevent the second arc welding robot 102 from moving up and down. The anti-loosening component 301 includes an anti-slip block 301a fixedly connected to the track 104, the length of the anti-slip block 301a is less than the length of the track 104, and a clamping block 301b cooperating with the anti-slip block 301a is provided in the guide groove 105.

[0035] During use, when the guide column 205d moves to the bottom of the inclined slide 205b of the electric slide rail, the clamping block 301b just moves to the lower side of the anti-slip block 301a on the track 104. At this time, the guide column 205d continues to move to the horizontal slide 205a at the lower end and continues to slide, allowing the second arc welding robot 102 to continue to move to the left. At this time, the upper end surface of the clamping block 301b is against the lower end surface of the anti-slip block 301a, and the second arc welding robot 102 is limited. At this time, the top of the guide groove 105 is against the upper end surface of the anti-slip block 301a, so that the second arc welding robot 102 cannot move up and down, making the limiting effect better.

[0036] In summary, by setting the anti-loosening component 301, when the second arc welding robot 102 moves on the track 104, the upper end surface of the clamping block 301b can be abutted against the lower end surface of the anti-slip block 301a, and the top of the guide groove 105 can be abutted against the upper end surface of the anti-slip block 301a, thereby preventing the second arc welding robot 102 from moving up and down, and making the fixing effect of the second arc welding robot 102 better.

[0037] Example 3, reference Figure 1 to Figure 6, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a fixing component 300 of a dual arc welding robot workstation, which solves the problem of how to further prevent the second arc welding robot 102 from moving left and right. Its pump air component 302 includes a pump air cavity 302a arranged in the base 201a, and the pump air cavity 302a is connected to the upper end of the mounting groove 201b through a pipeline 302b. A sealing gasket 302c sealed and slidably connected to the mounting groove 201b is embedded on the lifting block 201c, and a sliding plug 302d is sealed and slidably connected in the pump air cavity 302a. The elastic component 303 includes a connecting port 303a arranged at the lower end of the pump air cavity 302a and penetrating the base 201a. A limiting column 303b is slidably connected in the connecting port 303a. The limiting column 303b is elastically connected to the sliding plug 302d through a third spring 303c, and a limiting port 303d matched with the limiting column 303b is provided on the track 104.

[0038] Specifically, the third spring 303c is connected to a power source, and when the third spring 303c is energized, it can contract (for two adjacent circles of the third spring 303c, since the current directions are the same, according to the principle that currents in the same direction attract each other, an attraction will be generated between the circles of the third springs 303c, and this attraction will cause the third spring 303c to contract), thereby allowing the limit column 303b to disengage from the limit opening 303d on the track 104.

[0039] During use, when the lifting block 201c moves, the sealing gasket 302c moves upward, and the gas in the installation groove 201b can be pumped into the pump air cavity 302a through the pipeline 302b, so that the sliding plug 302d moves downward, thereby driving the limiting column 303b to move downward. When the guide column 205d moves on the inclined track 104, the limiting column 303b is not directly opposite to the limiting opening 303d. At this time, the lifting block 201c pumps air upward to make Hu Sai move downward, and the third spring 303c is compressed. When the guide column 205d moves to the desired position, the limiting column 303b is directly opposite to the limiting opening 303d. At this time, the third spring 303c is activated. Under the use, the limit column 303b is stuck in the limit opening 303d to prevent the limit column 303b from sliding left and right, front and back, thereby preventing the second arc welding robot 102 from sliding left and right, so that the second arc welding robot 102 can be better fixed. It should be noted that when the third spring 303c is energized and contracted, since the air pressure in the pump air chamber 302a still exists, the sliding plug 302d will not move upward, so that the contraction of the third spring 303c drives the limit column 303b to disengage from the limit opening 303d, and then the electric slide rail is started to reset the guide column 205d, so that the second arc welding robot 102 can be separated from the first arc welding robot 101.

[0040] In summary, by setting the fixing component 300, when the second arc welding robot 102 moves, the limiting column 303b can be inserted into the limiting opening 303d, thereby preventing the limiting column 303b from moving forward, backward, left and right, and preventing the second arc welding robot 102 from moving forward, backward, left and right, so that the fixing effect of the forward, backward, left and right movement is better, and there is no need to specially turn the bolts for fixing, and disassembly and installation are more convenient.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
