Description

Technical Field

[0001] This utility model relates to the field of pipe pile production, and in particular to a skirt plate rolling welding machine. Background Technology

[0002] As is well known, in the pipe pile industry, the skirt plate is composed of an end plate and an annular skirt. In the assembly process of the skirt plate, the end plate and the annular skirt are first connected together. Then, the pressing mechanism is rotated relative to the connected end plate and annular skirt, so that the pressing mechanism presses out the annular ribs on the annular skirt to fix the annular skirt to the end plate.

[0003] However, since the annular skirt is fixed to the end plate by means of the friction between the ring rib and the end plate, the end plate and the annular skirt, which are fixed together by the rib mechanism, are prone to relative rotation and detachment.

[0004] Therefore, there is an urgent need for a skirt plate rolling welding machine to overcome one or more of the above-mentioned defects. Utility Model Content

[0028] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] Please see Figure 1 The skirt board roll welding machine 100 of this utility model is suitable for performing circumferential roll welding between end plates 210 and annular skirt belts 220 that are pre-fixed together, so as to obtain Figure 10 The skirt panel 200 is shown. Because it is located between the end plate 210 and the annular skirt belt 220 (i.e.... Figure 3 Circumferential roll welding is performed at the position indicated by reference numeral 230, so a continuous roll weld structure 240 is formed between the end plate 210 and the annular skirt 220; obviously, depending on actual needs, a discontinuous (i.e., intermittent) roll weld structure 240 can also be formed between the end plate 210 and the annular skirt 220.

[0030] Combined Figure 2 and Figure 3 The skirt board welding machine 100 of this utility model includes a support assembly 10, a rotary driver 20, a first-side follower pressing member 30, a sliding body 40, a sliding driver 50, a second-side follower pressing member 60, and a welding torch 70. The support assembly 10 includes a first support rotating shaft 11 and a second support rotating shaft 12 that are spaced apart from each other and parallel in the X-axis direction. The first support rotating shaft 11 and the second support rotating shaft 12 extend beyond the first-side follower pressing member 30 in the Y-axis direction, as shown in the diagram. Figure 4As shown. The rotary actuator 20 is configured to drive the first support shaft 11 and the second support shaft 12 to rotate, so as to meet the need for both the first support shaft 11 and the second support shaft 12 to act as the active force, driving the end plate 210 and the annular skirt 220 to rotate together; obviously, depending on actual needs, the rotary actuator 20 can also be designed to drive either the first support shaft 11 or the second support shaft 12 to rotate; alternatively, in Figure 5 In this example, the rotary actuator 20 is located below the first supporting shaft 11 and the second supporting shaft 12. This design provides more space for the arrangement of the first side follower pressing member 30 above the supporting assembly 10. Furthermore, the output end 21 of the rotary actuator 20, the first supporting shaft 11, and the second supporting shaft 12 are all equipped with sprockets 90e. The sprockets 90e are connected by a chain drive, enabling the rotary actuator 20 to achieve synchronous rotation of the first supporting shaft 11 and the second supporting shaft 12 through the cooperation of the sprockets 90e and the chain. Obviously, depending on actual needs, pulleys and belts can also be used to replace the sprockets 90e and the chain; therefore, it is not considered... Figure 1 , Figure 2 and Figure 7 The above is the limit.

[0031] The second-side follower-up pressing member 60 is arranged opposite to the first-side follower-up pressing member 30 in the Y-axis direction to meet the requirement that the second-side follower-up pressing member 60 and the first-side follower-up pressing member 30 jointly press the pre-fixed end plate 210 and annular skirt 220 together in the Y-axis direction; the second-side follower-up pressing member 60 and the welding torch 70 are both mounted on the sliding body 40 to meet the requirement that the second-side follower-up pressing member 60 and the welding torch 70 follow the sliding body 40. The sliding body 40 can be reciprocated along the Y-axis direction, and the sliding driver 50 is configured to drive the sliding body 40 to slide closer to or away from the support assembly 10.

[0032] Therefore, during the roll welding process, the sliding actuator 50, through the sliding body 40, causes the second-side follower pressing member 60 and the first-side follower pressing member 30 to press the end plate 210 and the annular skirt 220 supported by the supporting assembly 10 together in the Y-axis direction; then, the rotation actuator 20 drives the first supporting shaft 11 and the second supporting shaft 12 to rotate synchronously. The synchronously rotating first supporting shaft 11 and the second supporting shaft 12 together drive the end plate 210 and the annular skirt 220, which are pre-fixed together, to rotate together, so that the welding torch 70 welds a continuous or discontinuous roll weld structure 240 between the end plate 210 and the annular skirt 220, thus achieving the desired result. Figure 10 The purpose of the skirt panel 200 shown is as follows. More specifically, as follows:

[0033] like Figures 1 to 3 and Figures 8 to 9As shown, as an example, the sliding body 40 includes a horizontal base 41 and a vertical plate 42 connected to the horizontal base 41. A second-side follower-up pressure member 60 is mounted on the side of the vertical plate 42 facing the first-side follower-up pressure member 30. A clearance space 421 is also provided through the vertical plate 42, in which the welding torch 70 is placed. This design makes the assembly of the second-side follower-up pressure member 60 on the sliding body 40 more compact, and also allows the vertical plate 42 to provide a barrier function during roll welding, preventing welding sparks from splashing onto the X-axis transfer module 90a, Y-axis transfer module 90c, and Z-axis transfer module 90b described below. Specifically, in Figure 2 and Figure 9 As an example, the second-side follower pressing member 60 includes a first follower pressing shaft 61 and a second follower pressing shaft 62 that are inclined relative to each other and spaced apart. The lower ends 611 (621) of the first follower pressing shaft 61 and the second follower pressing shaft 62 are close to each other. The welding torch 70 is arranged in the gap 613 between the lower ends 611 (621) of the first follower pressing shaft 61 and the second follower pressing shaft 62. This design enables the second-side follower pressing member 60 to be compatible with the roll welding operation of skirts 200 of different sizes (referring to radial dimensions), thereby improving the versatility of the skirt roll welding machine 100 of this utility model.

[0034] like Figure 3 and Figure 8 As shown, as an example, the skirt plate welding machine 100 of this utility model also includes a fixed base 80 located directly below the horizontal base 41. The horizontal base 41 is slidably mounted on the fixed base 80 along the Y-axis direction, and the fixed base 80 provides support for the reciprocating sliding of the sliding body 40 in the Y-axis direction. The fixed base 80 is provided with a bracket 81 that is higher than the horizontal base 41 in the Z-axis direction, and the sliding drive 50 is mounted on the bracket 81. At this time, the side of the vertical plate 42 facing away from the first side follower top pressing member 30 is arranged opposite to the sliding drive 50, and the output end of the sliding drive 50 is assembled and connected to the horizontal base 41. See the state below. Figure 8 As shown; this design offers the advantage of a more compact structure compared to arranging the sliding actuator 50 between the upright plate 42 and the support assembly 10. Specifically, in Figure 3 and Figure 8 As an example, the sliding actuator 50 may be, but is not limited to, a pneumatic or hydraulic cylinder, so that the sliding body 40 can quickly switch between two extreme positions, thereby improving the efficiency of the skirt welding machine 100 of this invention.

[0035] like Figures 1 to 3 and Figures 8 to 9As shown, as an example, the skirt plate roll welding machine 100 of this utility model also includes an X-axis transfer module 90a mounted on a horizontal base 41, a Z-axis transfer module 90b mounted on the output end 91 of the X-axis transfer module 90a, and a Y-axis transfer module 90c mounted on the output end 92 of the Z-axis transfer module 90b. The welding torch 70 is mounted on the output end 93 of the Y-axis transfer module 90c. Therefore, when roll welding skirt plates 200 of different sizes, the position of the welding torch 70 can be precisely adjusted by the X-axis transfer module 90a, the Y-axis transfer module 90c, and the Z-axis transfer module 90b, thereby ensuring the reliability of the skirt plate 200 roll welding. Specifically, in Figure 8 As an example, the output end 93 of the Y-axis transfer module 90c is connected to an L-shaped adapter 90d. The L-shaped adapter 90d includes a first extension section 94 extending along the Z-axis direction and connected to the output end 93, and a second extension section 95 extending along the Y-axis direction and away from the output end 93. The welding torch 70 is mounted on the second extension section 95, as shown in the diagram. Figure 8 As shown; therefore, by means of the L-shaped adapter 90d, the welding torch 70 is staggered from the Y-axis transfer module 90c in the Z-axis direction. For example, as an example, the X-axis transfer module 90a, Y-axis transfer module 90c and Z-axis transfer module 90b can all be structures composed of a motor, a lead screw and a lead nut, but are not limited thereto.

[0036] like Figures 3 to 5 As shown, as an example, the skirt welding machine 100 of this utility model also includes carbon brushes 90f located in contact with the first supporting shaft 11 and the second supporting shaft 12. Two first-side follower pressing members 30 are provided at the center between the first supporting shaft 11 and the second supporting shaft 12; two first-side follower pressing members 30 are provided near the carbon brushes 90f; and six first-side follower pressing members 30 are arranged in an inverted "V" shape above the carbon brushes 90f. Specifically, as an example, the first-side follower pressing members 30 are universal balls to effectively reduce the frictional resistance between the first-side follower pressing members 30 and the end plate 210.

[0037] Compared with the prior art, in the roll welding process, the pre-fixed end plate 210 and annular skirt 220 are first placed on the first supporting shaft 11 and the second supporting shaft 12. The first supporting shaft 11 and the second supporting shaft 12 support the annular skirt 220 and / or the end plate 210 from below, and the first side follower pressing member 30 presses against the end plate 210. Then, the sliding driver 50 drives the sliding body 40 together with the second side follower pressing member 60 and the welding torch 70 to slide towards the first follower pressing member 30 until the second side follower pressing member 60 presses against the annular skirt 220 and, together with the first side follower pressing member 30, presses against the annular skirt 220. The end plate 210 and the annular skirt 220 are pressed together in the Y-axis direction by the follower pressing member 30 on one side, while the welding gun 70 is located inside the annular skirt 220 at this time; then, the rotation driver 20 drives the first support shaft 11 and / or the second support shaft 12 to rotate, thereby driving the end plate 210 and the annular skirt 220, which are pre-fixed together, to rotate together, thus realizing the purpose of circumferential roll welding between the end plate 210 and the annular skirt 220 that are rotating together by the welding gun 70, thereby improving the stability and reliability between the end plate 210 and the annular skirt 220.

[0038] It should be noted that, at Figures 1 to 7 In this example, the supporting assembly 10, the rotary actuator 20, the carbon brush 90f, and the first-side follower pressing member 30 are each assembled into a frame 90g, which is arranged opposite to the sliding body 40 in the Y-axis direction. The rotary actuator 20 may be, but is not limited to, a motor. Furthermore, the end plate 210 and the annular skirt 220 can be pre-fixed together by spot welding.

[0039] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
