DETAILED DESCRIPTION

[0027] The features and exemplary embodiments of various aspects of the utility model will be described in detail below. In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the utility model, rather than to limit the utility model. For those skilled in the art, the utility model can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the utility model by showing examples of the utility model.

[0028] like Figure 3 As shown, the utility model provides a welding auxiliary tooling, which includes a base 1, two pushing devices 2 and a plurality of first positioning devices 3. A positioning space for placing a bucket plate 61 is provided on the base 1, and the length direction A of the positioning space is consistent with the length direction of the bucket plate 61, and the width direction B of the positioning space is consistent with the width direction of the bucket plate 61. The two pushing devices 2 are installed on the base 1 and are spaced apart on both sides of the positioning space in the width direction; the two pushing devices 2 are configured to be able to push the two side portions of the bucket plate 61 in the width direction respectively. The first positioning device 3 is installed on the base 1, wherein at least two first positioning devices 3 are respectively located on both sides of the positioning space in the width direction and are used to fix the bucket plate 61.

[0029] Specifically, after the bucket plate 61 is placed into the positioning space, the two pushing devices 2 can push the two side portions of the bucket plate 61 in the width direction to reduce the width of the bucket plate 61 to the target width, and then the first positioning device 3 for fixing the bucket plate 61 fixes the bucket plate 61 to position the bucket plate 61, and then the first left plate 62 and the right plate 63 are aligned with the bucket plate 61 respectively. Then welding can be performed. Therefore, in the production process, the pushing device 2 can replace manual work to push the bucket plate 61, and the first positioning device 3 can replace manual work to fix and position the bucket plate 61. Therefore, the welding auxiliary tooling can reduce labor intensity, reduce repeated fixing and alignment links, and improve production efficiency.

[0030] like Figure 3 As shown, in some embodiments of the present invention, the top surface of the base 1 is configured as a horizontally extending positioning surface, the pushing device 2 and the first positioning device 3 are installed on the positioning surface, and the positioning space is located above the positioning surface.

[0031] Specifically, the top surface of the base 1 extends horizontally, so the top surface of the base 1 is used as a positioning surface. The positioning space is located above the positioning surface and is fully exposed to the field of vision of on-site workers, which helps to quickly complete the welding operation and improve production efficiency; it also helps to ensure welding accuracy and improve product quality stability.

[0032] like Figure 3 As shown, in some embodiments of the present invention, a plurality of height-adjustable legs are provided at the bottom of the base 1 to meet processing requirements under different working conditions.

[0033] In some embodiments, the leg includes a support rod and a support block, the support rod extends vertically, the top of the support rod is connected to the bottom of the base 1, and the periphery of the bottom end of the support rod is provided with an annular connecting plate, which is connected to the support block through a plurality of vertically extending bolts. By turning the bolts, the distance between the support rod and the support block can be adjusted to achieve height adjustment of the leg. Of course, the present invention can adopt any other leg that can meet the use requirements, and the present invention is not limited.

[0034] like Figure 3 As shown, in some embodiments of the utility model, two first positioning devices 3 are respectively provided on both sides of the positioning space in the width direction, and are used to fix the bucket plate 61. Two first positioning devices 3 are respectively provided on both sides of the positioning space in the length direction, and are respectively used to fix the first left plate 62 and the right plate 63. Two pushing devices 2 are respectively provided on both sides of the positioning space in the width direction, and the pushing device 2 is located between the two first positioning devices 3 on the same side.

[0035] Specifically, there are four first positioning devices 3 for fixing the bucket plate 61, and they are respectively located on both sides of the positioning space in the width direction. For these four first positioning devices 3, the two first positioning devices 3 located on the same side are spaced apart, and a pushing device 2 is provided between the two first positioning devices 3 on the same side. In addition, there are two first positioning devices 3 for fixing the first left side plate 62, and they are both located on one side of the positioning space in the length direction, and the two first positioning devices 3 are spaced apart. In addition, there are two first positioning devices 3 for fixing the right side plate 63, and they are both located on the other side of the positioning space in the length direction, and the two first positioning devices 3 are also spaced apart.

[0036] In this embodiment, when manufacturing the double-mixing pump silo 6, the bucket plate 61 is first placed in the positioning space, and the opening of the bucket plate 61 faces the positioning surface, and then the two pushing devices 2 push the two sides of the bucket plate 61 respectively until the width of the bucket plate 61 gradually decreases to the target width, and the two pushing devices 2 stop pushing, and then the first positioning devices 3 on both sides fix the bucket plate 61 to keep the bucket plate 61 at the current size. Next, the first left side plate 62 is placed at the end of the bucket plate 61 and aligned, and then the two first positioning devices 3 nearby position and fix the first left side plate 62, and then the first left side plate 62 and the bucket plate 61 are welded. Next, the right side plate 63 is placed at the other end of the bucket plate 61 and aligned, and then the two first positioning devices 3 nearby position and fix the right side plate 63, and then the right side plate 63 and the bucket plate 61 are welded. Of course, the welding order of the first left side plate 62 and the right side plate 63 can be adjusted. Of course, the spliced ​​plates refer to the bucket plate 61 , the first left side plate 62 , the right side plate 63 and the second left side plate 64 .

[0037] In this embodiment, the pushing device 2 can push the bucket plate 61 to make the bucket plate 61 have a standard width; and all the first positioning devices 3 can fix and position the corresponding splicing plates respectively, so that each splicing plate remains aligned, reducing the labor intensity of workers and helping to improve production efficiency. Moreover, compared with the manual method, the pushing device 2 and the first positioning device 3 can achieve standardized operations, which helps to improve the stability of product quality.

[0038] like Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the first positioning device 3 includes a clamping drive mechanism 31 and a clamping mechanism 32, the fixing portion of the clamping drive mechanism 31 is connected to the positioning surface, the clamping mechanism 32 is connected to the driving portion of the clamping drive mechanism 31, and the clamping drive mechanism 31 can drive the clamping mechanism 32 to rotate between the first avoidance position and the clamping position. When the clamping mechanism 32 is located at the first avoidance position, the clamping mechanism 32 is away from the positioning space; when the clamping mechanism 32 is located at the clamping position, the clamping mechanism 32 can clamp the flange 65 at the positioning surface.

[0039] Specifically, when the splicing plate is not placed in the positioning space, the clamping mechanism 32 is located at the first avoidance position, so that the splicing plate can be smoothly placed in the positioning space. After the pushing action of the pushing device 2 is completed, the corresponding first positioning device 3 begins to implement the clamping, that is, the clamping drive mechanism 31 drives the clamping mechanism 32 to rotate from the first avoidance position to the clamping position, and the clamping mechanism 32 located at the clamping position can press the flange 65 of the bucket plate 61 vertically downward, so that the flange 65 of the bucket plate 61 is clamped on the positioning surface. Correspondingly, the clamping process of the flange 65 of the first left side plate 62 and the clamping process of the flap of the right side plate 63 can refer to the clamping process of the flange 65 of the bucket plate 61, and will not be repeated.

[0040] In this embodiment, after the bucket plate 61, the first left side plate 62 and the right side plate 63 are placed in the positioning space and aligned, each flange 65 can be abutted against the positioning surface. Therefore, after the pressing mechanism 32 presses the flange 65, the bucket plate 61, the first left side plate 62 and the right side plate 63 are firmly fixed on the positioning surface, and the pressing mechanism 32 does not damage the appearance of the bucket plate 61, the first left side plate 62 and the right side plate 63.

[0041] like Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments of the utility model, the clamping mechanism 32 includes a pressure rod 322 and a first connecting rod 321 which are perpendicular to each other. The first connecting rod 321 is connected to the driving part of the clamping driving mechanism 31. One end of the pressure rod 322 is connected to the first connecting rod 321, and the other end of the pressure rod 322 can vertically press the flange 65 downward.

[0042] Specifically, the clamping mechanism 32 is generally L-shaped. When the clamping mechanism 32 is in the clamping position, the first connecting rod 321 extends horizontally, the pressing rod 322 extends vertically, and the end of the pressing rod 322 is pressed against the flange 65. Since the force direction of the pressing rod 322 is perpendicular to the surface of the flange 65, the flange 65 can be pressed against the positioning surface.

[0043] In some other embodiments, the clamping mechanism 32 may also be a circular arc rod, and the angle of the circular arc may be 90 degrees. Of course, the clamping mechanism 32 may also be in other forms, and the present invention does not limit this.

[0044] In some embodiments of the present invention, the clamping drive mechanism 31 can be a welding clamping cylinder, such as the JCK welding clamping cylinder of AirTac. Specifically, the welding clamping cylinder includes a cylinder body and a swing arm. The cylinder body as a fixed part is installed on the base 1. The cylinder body can drive the swing arm as a driving part to rotate, and the clamping mechanism 32 is installed on the swing arm. Of course, the clamping drive mechanism 31 can also be a motor that can drive the clamping mechanism 32 to rotate, and the present invention does not limit it.

[0045] In other embodiments of the utility model, the first positioning device 3 includes a hydraulic angle cylinder, the cylinder body of the hydraulic angle cylinder is installed on the base 1, the piston rod can be extended and rotated in the cylinder body, and a swivel arm is provided at the free end of the piston rod, and a pressure block for tightening the flange 65 is provided on the swivel arm.

[0046] like Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the first positioning device 3 also includes a cushioning mechanism 33 installed on the positioning surface, the top surface of the cushioning mechanism 33 can place the splicing plate, and the clamping mechanism 32 located in the clamping position can press the flange 65 onto the cushioning mechanism 33.

[0047] Specifically, the pad mechanism 33 can support the splicing plate to a certain height, so that the pressing mechanism 32 can press the flange 65 .

[0048] like Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments of the utility model, the pad mechanism 33 includes a first pad 331, a second pad 332 and a third pad 333 stacked in sequence from top to bottom, the first pad 331 is installed on the positioning surface, the pressing drive mechanism 31 is connected to the second pad 332, and the top surface of the third pad 333 is used to place the splicing plate. The first positioning device 3 also includes a limiting mechanism 34, which is detachably connected to the side of the second pad 332, and the limiting mechanism 34 is configured to limit the horizontal movement of the splicing plate toward the outside of the positioning space.

[0049] Specifically, the first pad 331, the second pad 332 and the third pad 333 can support the splicing plate to a sufficient height, so that the pressing mechanism 32 can press the flange 65, and the shape and size requirements of the pressing mechanism 32 are reduced. Of course, the top surface of the third pad 333 is horizontal to facilitate the alignment of the splicing plate. In addition, after the splicing plate is fixed, a limiting mechanism 34 can be installed on the side of the second pad 332, and the limiting mechanism 34 can press against the outer side of the flange 65 to prevent the splicing plate from moving out of the positioning space.

[0050] Of course, the pad mechanism 33 may also be in any other form that can achieve the above technical effects, and the present utility model does not limit this.

[0051] In some embodiments, the position of the third pad 333 is adjustable. For example, the third pad 333 is bolted to the second pad 332, and a plurality of screw holes are provided at intervals on the top of the second pad 332; the bolts are installed in different screw holes, and the position of the third pad 333 can be adjusted to facilitate supporting the flange 65.

[0052] like Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments of the utility model, the limiting mechanism 34 includes a first limiting rod 341 and a second limiting rod 342. The first limiting rod 341 includes a first rod segment 3411 and a second rod segment 3412 connected to each other, the first rod segment 3411 is detachably connected to the side of the second cushion block 332, and the second rod segment 3412 extends vertically upward. The second limiting rod 342 includes a third rod segment 3421 and a fourth rod segment 3422 connected to each other, the third rod segment 3421 extends vertically and is detachably connected to the second rod segment 3412, and the fourth rod segment 3422 extends horizontally toward the positioning space and can be pressed against the outer side of the flange 65.

[0053] Specifically, the first limiting rod 341 and the second limiting rod 342 are generally L-shaped, and the two structures are simple. The second limiting rod 342 is connected to the side of the second cushion block 332 through the first limiting rod 341, and the first limiting rod 341 can make the installation position of the second limiting rod 342 higher and the connection stable, so as to limit the outer side of the flange 65.

[0054] Of course, the limiting mechanism 34 may also be in any other form that can achieve the above technical effects. For example, the limiting mechanism 34 may also be a Z-shaped rod, and the present utility model does not make any limitation thereto.

[0055] In some embodiments, the position of the first limiting rod 341 is adjustable. For example, the first rod segment 3411 is connected to the side of the second cushion block 332 by bolts, and the side of the second cushion block 332 is provided with a plurality of screw holes; by installing the bolts in different screw holes, the position of the first limiting rod 341 relative to the positioning space can be adjusted, thereby adjusting the position of the second limiting rod 342.

[0056] In some other embodiments, the position of the second limiting rod 342 is adjustable. For example, the third rod segment 3421 is connected to the second rod segment 3412 by bolts, and the second rod segment 3412 is provided with a plurality of screw holes; the height of the second limiting rod 342 can be adjusted by installing the bolts in different screw holes.

[0057] In some embodiments, the rear end of the second pad 332 faces away from the positioning space, and the front end of the second pad 332 faces the positioning space. The clamping drive mechanism 31 is connected to the rear end of the second pad 332, and the first rod segment 3411 is horizontally connected to the side of the second pad 332.

[0058] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the pushing device 2 includes a pushing drive mechanism 21 and a pushing mechanism 22, the fixing portion of the pushing drive mechanism 21 is connected to the positioning surface, the pushing mechanism 22 is connected to the driving portion of the pushing drive mechanism 21, and the pushing mechanism 22 can drive the pushing mechanism 22 to rotate between the second avoidance position and the pushing position. When the pushing mechanism 22 is located at the second avoidance position, the pushing mechanism 22 is away from the positioning space; when the pushing mechanism 22 is located at the pushing position, the pushing mechanism 22 can push the side of the bucket plate 61 in the width direction thereof.

[0059] Specifically, when the splicing plate is not placed in the positioning space, the pushing mechanism 22 is located at the second avoidance position, so that the splicing plate can be smoothly placed in the positioning space. After the bucket plate 61 is placed in the positioning space, the pushing drive mechanism 21 drives the pushing mechanism 22 to rotate from the second avoidance position to the pushing position, and the pushing mechanism 22 located at the pushing position can push the side of the bucket plate 61 in its width direction. Under the pushing of the two pushing mechanisms 22, the width of the bucket plate 61 is gradually reduced to the target size, and then the first positioning device 3 implements positioning and fixing. Therefore, the pushing device 2 can replace manual pushing, reduce the labor intensity of workers, and improve production efficiency; and the force application process of the pushing device 2 is more stable, which helps to ensure product quality.

[0060] In some embodiments of the present invention, the push drive mechanism 21 can be a welding clamping cylinder, such as the JCK welding clamping cylinder of AirTac. Specifically, the welding clamping cylinder includes a cylinder body and a swing arm. The cylinder body as a fixed part is installed on the base 1. The cylinder body can drive the swing arm as a driving part to rotate, and the push mechanism 22 is installed on the swing arm. Of course, the push drive mechanism 21 can also be a motor that can drive the push mechanism 22 to rotate, and the present invention does not limit it.

[0061] like Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the pushing mechanism 22 includes a second connecting rod 221 and a horizontally extending push rod 222 , and the middle portion of the push rod 222 is connected to the driving portion of the pushing drive mechanism 21 through the second connecting rod 221 .

[0062] Specifically, the side of the push rod 222 pushes the side of the bucket plate 61. Since the force application surface of the side of the push rod 222 is large, deformation of the side of the bucket plate 61 due to local large force is avoided, and it also helps to make the width of the bucket plate 61 consistent, thereby ensuring the stability of product quality.

[0063] Of course, the pushing mechanism 22 can also be any other form that can achieve the above technical effects, and the utility model does not limit it. For example, the pushing mechanism 22 includes a wheel frame and a plurality of rollers, the wheel frame is connected to the driving part of the pushing driving mechanism 21, and the rollers are installed on the wheel frame at intervals, and the rollers push the side of the bucket plate 61.

[0064] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments of the utility model, the pushing device 2 includes a bracket 23 extending upwardly inclined, the bottom end of the bracket 23 is connected to the positioning surface, the top end of the bracket 23 is closer to the positioning space relative to the bottom end of the bracket 23, and the pushing drive mechanism 21 is connected to the bracket 23.

[0065] Specifically, the bracket 23 extends at an angle, and the pushing device 2 installed on the bracket 23 is also in an inclined state, so that the force application position of the pushing mechanism 22 is in the middle of the side of the bucket plate 61, and the force application direction is inclined downward, which helps to make the width of the bucket plate 61 change evenly during the pushing process, thereby ensuring product quality.
