[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figures 1-4 As shown, a welding platform for a welding robot that avoids welding dead angles includes an annular base 1. A circular array of splicing plates 3 is movably disposed within an annular groove 11 at the top of the annular base 1. Each pair of splicing plates 3 is fitted together. An inner arc-shaped plate 37 and an outer arc-shaped plate 31 are fixedly mounted on the top of each splicing plate 3. A slider 2 is movably disposed between the inner arc-shaped plate 37 and the outer arc-shaped plate 31. By arranging multiple splicing plates 3 in a circular array within the annular groove 11, when the slider 2, used to mount the welding robot, slides between the inner arc-shaped plate 37 and the outer arc-shaped plate 31 at the top of the splicing plate 3, the contact friction between the slider 2 and the inner arc-shaped plate 37 and the outer arc-shaped plate 31 causes severe wear in a certain area. Only the splicing plates 3 in that area need to be replaced, thus saving maintenance costs.

[0026] As the further provided technical scheme of the utility model, still include spacing annular board 4, and spacing annular board 4 is pressed on the extension edge 33 of the spliced plate 3 respectively.

[0027] Specifically, by using the spacing annular board 4 to press on the extension edge 33 of the plurality of spliced plates 3, the plurality of spliced plates 3 can be limited.

[0028] Further, the perforation on the spacing annular board 4 and the threaded hole on the top of the annular base 1 are matched with each other, and the hexagonal socket head cap screw 41 is movably arranged in the perforation and the threaded hole.

[0029] Specifically, by making the hexagonal socket head cap screw 41 pass through the perforation and threadedly rotate in the threaded hole on the annular base 1, the spacing annular board 4 is fixedly installed on the annular base 1 and the plurality of spliced plates 3 are fixed, and by disassembling the spacing annular board 4, the spliced plate 3 can be exposed and the limitation on the spliced plate 3 can be released.

[0030] Further, the outer arc-shaped plate 31 is fixedly installed with the baffle 32 on the outer wall of one side of the inner arc-shaped plate 37, and the convex edge 21 on the sliding block 2 is located below the baffle 32.

[0031] Specifically, by sliding the sliding block 2 between the spliced plate 3 and the baffle 32, and then swinging the mechanical arm on the sliding block 2 to weld the annular base 1, at this time, the upward thrust of the convex edge 21 is increased, and the baffle 32 is used to stably shield and limit the convex edge 21, so as to improve the stability of the sliding block 2.

[0032] Further, the outer arc-shaped plate 31 is provided with the fine flow oil channel 36 on the opposite two sides respectively, and the fine flow oil channels 36 on every two adjacent outer arc-shaped plates 31 are matched and connected with each other.

[0033] Specifically, by loosening the oil in the oil cavity connected between the fine flow oil channels 36 of every two adjacent outer arc-shaped plates 31, the oil flows along the fine flow oil channel 36 to one end of the fine flow oil channel 36 below the baffle 32, so as to spray oil on the convex edge 21 to reduce the friction between the convex edge 21 and the baffle 32.

[0034] Further, the outer arc-shaped plate 31 is provided with the wide flow oil channel 35 connected with the fine flow oil channel 36 on the opposite two sides respectively.

[0035] Specifically, when the oil flows along the wide flow oil channel 35 into the fine flow oil channel 36, the flow rate of the lubricating oil is accelerated due to the narrowing of the flow channel, and when the lubricating oil is sprayed at the end of the fine flow oil channel 36, a strong splashing intensity is generated, so as to enhance the oil spraying range of the convex edge 21.

[0036] Further, the splicing plate 3 is provided with an oil collecting groove 34 communicated with the wide flow oil channel 35 at two opposite sides.

[0037] Specifically, the pressing block 5 slides into the oil collecting groove 34 to extrude the lubricating oil accumulated in the oil collecting groove 34, and the lubricating oil flows to the fine flow oil channel 36 along the wide flow oil channel 35 for oil injection lubrication.

[0038] Further, the inner wall of the oil collecting groove 34 is fixedly provided with an elastic plate 52, the pressing block 5 is provided with an oil inlet 51, and the elastic plate 52 pushes the pressing block 5 by default to make the oil inlet 51 higher than the top of the splicing plate 3.

[0039] Specifically, the elastic plate 52 pushes the pressing block 5 by default to make the oil inlet 51 higher than the top of the splicing plate 3, so that the lubricating oil at the top of the splicing plate 3 flows along the oil inlet 51 into the oil collecting groove 34 for collection, and then when the pressing block 5 slides into the oil collecting groove 34, the oil inlet 51 is shielded by the inner wall of the oil collecting groove 34, so that the lubricating oil in the oil collecting groove 34 is extruded by the pressing block 5 to enter the wide flow oil channel 35.

[0040] Further, the sliding block 2 is slidably provided with a pressing piece 6, and the pressing piece 6 and the sliding block 2 are fixedly provided with a pushing spring 61, and the extrusion wheel 62 rotatably arranged on the pressing piece 6 is movably arranged on the plurality of pressing blocks 5.

[0041] Specifically, the elastic force of the pushing spring 61 is greater than the elastic force of the elastic plate 52, and when the sliding block 2 slides on the top of the plurality of pressing pieces 6, the extrusion wheel 62 is extruded by the elastic plate 52 to push the pressing block 5 downward and extrude the lubricating oil in the oil collecting groove 34 to flow into the wide flow oil channel 35.

[0042] Further, the sliding block 2 is rotatably provided with an auxiliary wheel 63 on the outer wall of one side of the outer arc plate 31.

[0043] Specifically, the auxiliary wheel 63 is used to reduce the friction between the sliding block 2 and the outer arc plate 31.

[0044] Working principle: through the circular array arrangement of multiple splicing plates 3 in the annular groove 11, and then when the slider 2 for installing the welding robot slides between the inner arc plate 37 and the outer arc plate 31 on the top of the splicing plate 3, the slider 2 and the inner arc plate 37 and the outer arc plate 31 are in contact and friction, and then when the splicing plate 3 and the inner arc plate 37 and the outer arc plate 31 in a certain area are seriously worn, only the splicing plate 3 in the area is replaced, thereby saving the maintenance cost. When the slider 2 slides on the top of the plurality of pressing pieces 6, the elastic plate 52 pushes the extrusion wheel 62 to extrude the pressing block 5, so that the pressing block 5 moves downward and extrudes the lubricating oil in the oil collecting groove 34 to flow into the wide oil flow channel 35, and then the lubricating oil flows along the wide oil flow channel 35 to the fine oil flow channel 36 to spray oil lubrication, so as to reduce the friction between the convex edge 21 and the baffle 32.

[0045] The above only describes some exemplary embodiments of the utility model by way of illustration, without doubt, for ordinary skilled in the art, under the condition that the spirit and scope of the utility model are not deviated, the described embodiments can be modified in various different ways.
