Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] This utility model provides a large component repair platform, the structure of which is as follows: Figure 1 and Figure 2As shown, the system includes a support mechanism 100, a first drive mechanism 200, and a second drive mechanism 300. The support mechanism 100 includes multiple support blocks 110, which are arranged in a rectangular array on the same horizontal plane, with the top surface of each support block 110 forming a support surface. The first drive mechanism 200 includes a first drive assembly 210 and multiple first connecting frames 220. The first drive assembly 210 is connected to one of the support blocks 110 arranged along the Y direction, and the first connecting frames 220 connect two adjacent support blocks 110 along the X direction. The first drive assembly 210 is used to drive each support block 110. The support block 110 moves along the X direction, and the first connecting frame 220 can synchronously increase or decrease the spacing between adjacent support blocks 110 in the X direction; the second driving mechanism 300 includes a second driving component 310 and a plurality of second connecting frames 320. The second driving component 310 is connected to one of the support blocks 110 arranged along the X direction, and the second connecting frame 320 connects two adjacent support blocks 110 along the Y direction. The second driving component 310 is used to drive each support block 110 to move along the Y direction, and the second connecting frame 320 can synchronously increase or decrease the spacing between adjacent support blocks 110 in the Y direction.

[0019] In use, the area of ​​the support surface is adjusted according to the size of the large component to be repaired. By manipulating the first drive component 210, the first drive component 210 can drive each support block 110 to move along the X direction. Then, through the linkage of each of the first connecting frames 220, the distance between adjacent support blocks 110 in the X direction can be increased or decreased synchronously. By manipulating the second drive component 310, the second drive component 310 can drive each support block 110 to move along the Y direction. Then, through the linkage of each of the second connecting frames 320, the distance between adjacent support blocks 110 in the Y direction can be increased or decreased synchronously. When the distance between adjacent support blocks 110 in the X direction and the distance in the Y direction change, the area of ​​the support surface changes accordingly. In this large component repair platform, the area of ​​the support surface can be adjusted in real time according to the size of different large components. When a large component is placed on the support surface, the support surface is subjected to uniform force and is not easily deformed, thereby ensuring the repair accuracy of large workpieces.

[0020] As a preferred embodiment, please refer to Figure 3 Each of the support blocks 110 has multiple insertion holes 111 on its top surface, and the insertion holes 111 are distributed in a rectangular array structure.

Each of the first slide rails 230 is parallel to each other on the same horizontal plane and extends along the X direction. Each of the second slide rails 240 is parallel to each other on the same horizontal plane and extends along the Y direction. The first second slide rail 240 is fixedly connected to each of the first slide rails 230, and the remaining second slide rails 240 are slidably connected to each of the first slide rails 230, and can all reciprocate along the length direction of each of the first slide rails 230.

The last second slide rail 240 is slidably connected to the remaining support blocks 110 of the first column arranged in the Y direction. Each of the remaining second slide rails 240 is slidably connected to each column of support blocks 110 arranged in the Y direction. The first drive assembly 210 is connected to the last second slide rail 240 and is used to drive the last second slide rail 240 to move. Each first connecting frame 220 has a first telescopic structure. Each first connecting frame 220 is connected to two adjacent second slide rails 240 in the X direction. The first connecting frames 220 are connected in a one-to-one correspondence to each other, so that the movement of the last second slide rail 240 is converted into the sequential movement of each second slide rail 240. By controlling the first driving component 210, the first driving component 210 can drive the last second slide rail 240 to move back and forth along the length direction of each first slide rail 230. When the last second slide rail 240 moves back and forth along the length direction of each first slide rail 230, the movement of the last second slide rail 240 can be converted into the synchronous movement of each second slide rail 240 through the linkage of each first connecting frame 220, thereby adjusting the spacing of adjacent second slide rails 240 in the X direction, and thus realizing the adjustment of the spacing of each support block 110 in the X direction.

The first drive plate 212 has a first screw hole and is sleeved on the first lead screw 211 through the first screw hole. The first screw hole is threadedly connected to the first lead screw 211. The output end of the first rotation drive member 213 is connected to one end of the first lead screw 211 to drive the first lead screw 211 to rotate. When the first rotation drive member 213 is activated, The first rotating drive member 213 drives the first lead screw 211 to rotate in the forward or reverse direction, and drives the last second slide rail 240 to reciprocate along the length direction of each first slide rail 230 via the first drive plate 212. When the last second slide rail 240 reciprocates along the length direction of each first slide rail 230, the movement of the last second slide rail 240 can be converted into the synchronous movement of each second slide rail 240 through the linkage of each first connecting frame 220, thereby adjusting the spacing of adjacent second slide rails 240 in the X direction, and thus realizing the adjustment of the spacing of each support block 110 in the X direction.

[0023] In a preferred embodiment, the first rotation drive 213 is a first motor.

[0024] As a preferred embodiment, please refer to Figure 1 and Figure 2 Each of the first connecting frames 220 includes two first connecting rods 221 arranged in a cross configuration.

Adjacent first telescopic structures are hinged end to end. The rotary shaft at the intersection of the two first connecting rods 221 is fixedly connected to the other end of the second slide rail 240. When the included angle of the two connecting rods changes, the distance between the two ends of the first telescopic structure changes accordingly. When the first driving component 210 drives the last second slide rail 240 to reciprocate along the length direction of each of the first slide rails 230, a linkage effect can be formed through each of the first connecting frames 220, driving each of the second slide rails 240 to move synchronously, thereby adjusting the distance between adjacent second slide rails 240 in the X direction, and thus realizing the adjustment of the distance between each of the support blocks 110 in the X direction.

[0025] As a preferred embodiment, please refer to Figure 1 and Figure 2The second drive mechanism 300 further includes multiple connecting shafts 330, each of which is parallel to each other on the same horizontal plane and extends along the X direction. Each connecting shaft 330 is fixedly connected to the first and last support blocks 110 of each row arranged along the X direction, and each connecting shaft 330 is slidably connected to the remaining support blocks 110 of each row arranged along the X direction. The second drive assembly 310 is connected to the last support block 110 of the first row arranged along the X direction, and is used to drive the last support block 110 of the first column to move. Each second connecting frame 320 has a second telescopic structure, and each second connecting frame 320 is connected to each support block 110 of the first column. Adjacent second connecting frames 320 are interconnected. The movement of the last support block 110 in the first column is converted into the sequential movement of each support block 110 in the first column. By manipulating the second drive component 310, the second drive component 310 can drive the last support block 110 in the first column to move back and forth along the length direction of the second slide rail 240. When the last support block 110 in the first column moves back and forth along the length direction of the second slide rail 240, the movement of the last support block 110 in the first column can be converted into the synchronous movement of each support block 110 in the first column through the linkage of each second connecting frame 320, thereby adjusting the spacing of each support block 110 in the first column in the Y direction. Furthermore, due to the limiting effect of each connecting shaft 330, the spacing of each support block 110 in the Y direction can be adjusted.

[0026] As a preferred embodiment, please refer to Figure 1 and Figure 2The second drive assembly 310 includes a second lead screw 311, a second drive plate 312, and a second rotation drive member 313. The second lead screw 311 is parallel to the second slide rail 240. The second drive plate 312 is fixedly connected to the support block 110 at the end of the first row. The second drive plate 312 has a second screw hole and is sleeved on the second lead screw 311 through the second screw hole. The second screw hole is threadedly connected to the second lead screw 311. The output end of the second rotation drive member 313 is connected to one end of the second lead screw 311 to drive the second lead screw 311 to rotate. When the second rotation drive member 313 is activated, the second rotation drive member 311... 3 drives the second lead screw 311 to rotate in the forward or reverse direction, and drives the last support block 110 of the first column to reciprocate along the length direction of the second slide rail 240 via the second drive plate 312. When the last support block 110 of the first column reciprocates along the length direction of the second slide rail 240, the movement of the last support block 110 of the first column can be converted into the synchronous movement of each support block 110 of the first column through the linkage of each second connecting frame 320, thereby adjusting the spacing of each support block 110 of the first column in the Y direction. Furthermore, due to the limiting effect of each connecting shaft 330, the spacing of each support block 110 in the Y direction can be adjusted.

[0027] In a preferred embodiment, the second rotation drive 313 is a second motor.

[0028] As a preferred embodiment, please refer to Figure 1 and Figure 2 Each of the second connecting frames 320 includes two intersecting second connecting rods 321.

When the included angle of the two second connecting rods 321 changes, the distance between the two ends of the second telescopic structure changes accordingly. When the second drive assembly 310 drives the last support block 110 of the first row to reciprocate along the length direction of the second slide rail 240, a linkage effect can be formed through each of the second connecting frames 320, driving each of the support blocks 110 in the first row to move synchronously, thereby adjusting the spacing of each support block 110 in the first row in the Y direction. Furthermore, due to the limiting effect of each connecting shaft 330, the spacing of each support block 110 in the Y direction can be adjusted.

[0029] In a preferred embodiment, the large component repair platform further includes a positioning mechanism, which is detachably connected to the support block 110 and is used to position the large component to prevent it from moving during the repair process.

[0032] To better understand this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of the technical solution of this utility model will be described in detail below: In use, the area of ​​the support surface is adjusted according to the size of the large component to be repaired. The first rotation drive 213 is activated, driving the first lead screw 211 to rotate forward or backward, and via the first drive plate 212, the last second slide rail 240 reciprocates along the length direction of each first slide rail 230. When the last second slide rail 240 reciprocates along the length direction of each first slide rail 230, the movement of the last second slide rail 240 can be converted into the synchronous movement of each second slide rail 240 through the linkage of each first connecting frame 220, thereby adjusting the spacing of adjacent second slide rails 240 in the X direction, and thus realizing the adjustment of the spacing of each support block 110 in the X direction. The second rotation drive 313 is activated, driving the second lead screw 311 to rotate forward or backward, and via the second drive plate 312, the last support block 110 in the first row reciprocates along the length direction of each first slide rail 230. The second slide rail 240 reciprocates along its length. When the last support block 110 of the first column reciprocates along the length of the second slide rail 240, the movement of the last support block 110 of the first column can be converted into the synchronous movement of all the support blocks 110 of the first column through the linkage of each of the second connecting frames 320. This adjusts the spacing of each support block 110 in the Y direction. Due to the limiting effect of each connecting shaft 330, the spacing of each support block 110 in the Y direction can be adjusted. Since the top surface of each support block 110 forms the support surface, when the spacing of adjacent support blocks 110 in the X direction and the spacing in the Y direction changes, the area of ​​the support surface changes accordingly. In this large component repair platform, the area of ​​the support surface can be adjusted in real time according to the size of different large components. When a large component is placed on the support surface, the support surface is subjected to uniform force and is not easily deformed, thereby ensuring the repair accuracy of large workpieces.

[0033] The large component repair platform provided by this utility model has the following beneficial effects: (1) Each of the pins is set on the side of the large component to enclose and form the outline of the large component. The lower end of each pin is inserted into the corresponding insertion hole 111. The upper end of each pin abuts against the large component, which can prevent the large component from moving during the repair process. The positioning mechanism is easy to assemble and disassemble and has high positioning accuracy. (2) Since the top surface of each of the support blocks 110 forms the support surface, when the spacing between adjacent support blocks 110 in the X direction and the spacing in the Y direction change, the area of ​​the support surface changes accordingly. (3) In this large component repair platform, the area of ​​the support surface can be adjusted in real time according to the size of different large components. When the large component is placed on the support surface, the support surface is subjected to uniform force and is not easy to deform, thereby ensuring the repair accuracy of large workpieces.

Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
