The two groups of reverse deformation support structures and the two groups of non-deformation support structures are symmetrically arranged on the transverse two sides of the bottom plate middle support structure. The support surface in the bottom plate middle support structure is at the same height as the support surface in the non-deformation support structure and is higher than the support surface in the reverse deformation support structure.

[0010] In the anti-deformation positioning and clamping mode, the edge portion of the bottom plate can be pressed between the anti-deformation support structure and the bottom plate edge portion pressing mechanism; in the non-deformation positioning and clamping mode, the edge portion of the bottom plate can be pressed between the non-deformation support structure and the bottom plate edge portion pressing mechanism.

[0018] Optionally, the anti-deformation support structure comprises an anti-deformation support block connected to the pressing head seat body and arranged in spacing apart below the edge portion pressing head.

[0019] Optionally, the accompanying tooling comprises a plurality of bottom plate predetermined positioning pins arranged on the tooling platform, at least part of the bottom plate predetermined positioning pins being detachably connected to the tooling platform.

[0024] A transfer device is provided with a device outer positioning structure for detachable cooperation with the tool outer positioning structure, and the transfer device is arranged to be capable of transferring the travelling tool to any one of the welding operation base stations.

[0025] In consideration of welding deformation generated in the process of manufacturing the rotary table structure, and in combination with the general regularity of welding deformation summarized from actual production experience, the present application can effectively reduce the influence of welding deformation on the manufacturing precision of the rotary table structure by specially designing the positioning and clamping assembly in the travelling tool.

[0026] In the process of welding the two upright plates of the rotary table structure to the bottom plate, the positioning and clamping assembly first positions and clamps the bottom plate in an anti-deformation positioning and clamping mode, so as to implement anti-deformation welding of the two upright plates, and thus the deformation amplitude of the bottom plate will not be too large after welding is completed and the positioning and clamping is released, thereby ensuring the perpendicularity of the two upright plates to the bottom plate, and ensuring the spacing precision of the two upright plates. In the case that the perpendicularity of the upright plates and the spacing precision of the upright plates are both ensured, the positioning and clamping assembly can be switched to position and clamp the bottom plate in a non-deformation positioning and clamping mode, and at this time, the two shaft sleeves are welded to the two upright plates respectively, so as to ensure the spacing precision and coaxiality of the two shaft sleeves.

[0055] The specific embodiments of the present application will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0056] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0057] In the embodiments of the present application, the orientation words such as "upper", "lower", "top", "bottom" are generally used for the directions shown in the drawings or the positional relationship between the components in the vertical, perpendicular or gravity direction, unless otherwise specified.

[0058] The present application will be described in detail below with reference to the drawings and in conjunction with exemplary embodiments.

[0059] Reference Figure 1 , the first exemplary embodiment of the present application provides a traveling tool 100, which mainly comprises a tooling platform 101 and a positioning and clamping assembly.

[0060] Specifically, the tooling platform 101 is used to carry the turntable structure 500 to be welded (refer to Figure 8 ), including carrying the turntable structure 500 in different forms during welding, such as carrying the bottom plate 502, carrying the welding assembly composed of the vertical plate 501 and the bottom plate 502, and carrying the welding assembly composed of the vertical plate 501, the bottom plate 502 and the shaft sleeve 503, etc. The turntable structure 500 can be a turntable structure of a concrete pump truck. In addition, the positioning and clamping assembly is arranged on the tooling platform 101 and can be switched between the reverse deformation positioning and clamping mode and the non-deformation positioning and clamping mode, so as to position and clamp the bottom plate 502 in different modes according to different welding steps.

[0061] In consideration of the welding deformation of the turntable structure 500 in the manufacturing process, and in combination with the general regularity of the welding deformation summarized from the actual production experience, the positioning and clamping assembly in the traveling tool 100 is specially designed in the example embodiment, so as to effectively reduce the influence of the welding deformation on the manufacturing precision of the turntable structure 500.

[0062] In the process of welding the two vertical plates 501 to the base plate 502, the positioning and clamping assembly first positions and clamps the base plate 502 in the anti-deformation positioning and clamping mode, so that the anti-deformation welding of the two vertical plates 501 can be implemented. After the welding is completed and the positioning and clamping is released, the deformation amplitude of the base plate 502 will not be too large (i.e. the pre-welding anti-deformation offsets the post-welding deformation), so as to ensure the perpendicularity of the two vertical plates 501 to the base plate 502, and the spacing accuracy of the two vertical plates 501. In the case that the perpendicularity of the vertical plates and the spacing accuracy of the vertical plates are ensured, the positioning and clamping assembly can be switched to position and clamp the base plate 502 in the non-deformation positioning and clamping mode, and then the two shaft sleeves 503 are welded to the two vertical plates 501 respectively, so as to ensure the spacing accuracy and coaxiality of the two shaft sleeves 503.

[0063] It can be seen that, by using the traveling tool 100 of the example embodiment to assist the welding of the turntable structure 500, the influence of the welding deformation on the manufacturing precision of the turntable structure can be effectively reduced, so as to improve the quality and the qualification rate of the turntable structure 500.

[0064] A general regularity of the welding deformation of the turntable structure 500 is that the base plate 502 will present a shape of the middle part being concave and the edge part being raised after the two vertical plates 501 are welded. For this kind of welding deformation, the positioning and clamping assembly of the traveling tool 100 can be set as follows.

[0065] Specifically, the positioning and clamping assembly can include a base plate middle part supporting structure, two groups of anti-deformation supporting structures, two groups of non-deformation supporting structures, and a plurality of base plate edge part pressing mechanisms. The two groups of anti-deformation supporting structures are symmetrically arranged on the transverse two sides of the base plate middle part supporting structure, and the two groups of non-deformation supporting structures are also symmetrically arranged on the transverse two sides of the base plate middle part supporting structure.

[0066] In order to realize the non-deformation positioning and clamping mode and the anti-deformation positioning and clamping mode of the positioning and clamping assembly, one is to set the supporting surface in the base plate middle part supporting structure (i.e. the supporting surface for supporting the middle part of the bottom surface of the base plate 502) and the supporting surface in the non-deformation supporting structure (i.e. the supporting surface for supporting the edge part of the bottom surface of the base plate 502) as the same height surface, and the other is to set the supporting surface in the base plate middle part supporting structure to be higher than the supporting surface in the anti-deformation supporting structure (i.e. the supporting surface for supporting the edge part of the bottom surface of the base plate 502).

[0067] In the anti-deformation positioning and clamping mode, the middle part of the bottom plate 502 is supported by the bottom plate middle part support structure, and the edge part of the bottom plate 502 is pressed between the anti-deformation support structure and the bottom plate edge part pressing mechanism. Since the support surface in the bottom plate middle part support structure is higher than the support surface in the anti-deformation support structure, the bottom plate 502 is positioned and clamped into a shape with the middle part convex upward and the edge part inclined downward, so that the anti-deformation method can be used to weld the upright plate 501 to the bottom plate 502, thereby ensuring the spacing accuracy and perpendicularity of the upright plate 501.

[0068] In the non-deformation positioning and clamping mode, the middle part of the bottom plate 502 is supported by the bottom plate middle part support structure, and the edge part of the bottom plate 502 is pressed between the non-deformation support structure and the bottom plate edge part pressing mechanism. Since the support surface in the bottom plate middle part support structure is the same as the support surface in the non-deformation support structure, the bottom plate 502 is positioned and clamped into a flat shape or a substantially flat shape, so that two shaft sleeves 503 can be further welded on the two upright plates 501 respectively, thereby ensuring the spacing accuracy and coaxiality of the two shaft sleeves 503.

[0069] Referring to Figures 1 to 3 The bottom plate middle part support structure can include two middle part support rods 102, which are parallel and spaced apart along a first direction and respectively extend along a second direction perpendicular to the first direction. The top surfaces of the two middle part support rods 102 are formed as the support surfaces in the bottom plate middle part support structure described above. After the bottom plate 502 is positioned and clamped in the anti-deformation mode, the two middle part support rods 102 are aligned with the positions of the two upright plates 501 to be welded on the bottom plate 502, thereby providing more stable support for the bottom plate 502 during the welding of the two upright plates 501.

[0070] Further, the two middle part support rods 102 are arranged to be adjustable in the spacing between them in the first direction, so as to be compatible with the manufacture of the turntable structure 500 with different upright plate spacings, thereby improving the versatility of the accompanying tooling 100. For example, the bottom plate middle part support structure can further include a plurality of support rod guide rails 103, which are parallel and spaced apart along the second direction in sequence and respectively extend along the first direction. By sliding at least one of the two middle part support rods 102 with the plurality of support rod guide rails 103, at least one middle part support rod 102 can slide in the first direction, so as to adjust the spacing between the two middle part support rods 102 in the first direction. This has the advantages of simple structure, easy processing, convenient operation, etc. When the middle part support rod 102 needs to be replaced due to excessive wear, it can be quickly disassembled and replaced, thereby saving maintenance time and cost.

[0071] In addition, the non-deformation support structure can comprise a non-deformation support block 104, a top surface of which is formed as a support surface in the non-deformation support structure described above, and which is arranged to be able to adjust its radial position on the tooling platform 101 to move into or out of the lower side of the base plate 502, and to be compatible with the edge non-deformation support of the base plate 502 with different diameters.

[0072] Referring to Figure 3 In the non-deformation positioning and clamping mode, the non-deformation support block 104 moves into the lower side of the base plate 502, and cooperates with the base plate edge pressing mechanism to press the edge of the base plate 502. Figure 2 In the reverse deformation positioning and clamping mode, the non-deformation support block 104 is on the radial outside of the base plate 502, and does not form a support for the edge of the base plate 502.

[0073] The non-deformation support structure can also comprise a support block guide rail 105 arranged to extend radially along the tooling platform 101, and in this case, the non-deformation support block 104 is able to adjust its radial position on the tooling platform 101 by sliding cooperation with the support block guide rail 105, which has the advantages of simple structure, easy processing, convenient operation, etc., and when the non-deformation support block 104 needs to be replaced due to excessive wear, it can be quickly disassembled and replaced, saving maintenance time and cost.

[0074] In addition, the base plate edge pressing mechanism can comprise an edge pressing head 106 arranged to be able to move up and down (which can be driven by a hydraulic pump 109 arranged on the tooling platform 101) and adjust its radial position on the tooling platform 101, that is, the edge pressing head 106 can not only press or release the edge of the base plate 502 by moving up and down, but also can be compatible with the clamping of the base plate 502 with different diameters by adjusting its radial position on the tooling platform 101, thereby improving the versatility of the accompanying tooling 100.

[0075] For example, the base plate edge pressing mechanism can also comprise a pressing head seat body 107 and a seat guide rail 108, in which case the edge pressing head 106 is connected to the pressing head seat body 107 in a manner that can move up and down, and the seat guide rail 108 is arranged to extend radially along the tooling platform 101, and the pressing head seat body 107 is able to adjust its radial position on the tooling platform 101 by sliding cooperation with the seat guide rail 108, thereby synchronously driving the edge pressing head 106 to adjust its radial position on the tooling platform 101, which has the advantages of simple structure, easy processing, convenient operation, etc., and when the edge pressing head 106 and the pressing head seat body 107 need to be replaced due to excessive wear, it can be quickly disassembled and replaced, saving maintenance time and cost.

[0076] Referring to Figure 1Two seat body guides 108 can be arranged in parallel and spaced apart in the edge portion pressing mechanism, and a T-shaped sliding groove is defined by the two seat body guides 108, and the pressing head seat 107 is slidably engaged with the T-shaped sliding groove, so that the radial position of the pressing head seat 107 and the edge portion pressing head 106 on the tooling platform 101 can be synchronously adjusted.

[0077] In addition, the anti-deformation support structure can include an anti-deformation support block 110, the top surface of which is formed as the support surface in the anti-deformation support structure described above. For the purpose of simplifying the tooling structure, the anti-deformation support block 110 can be connected to the pressing head seat 107 and arranged in spaced apart below the edge portion pressing head 106, so that the radial position of the anti-deformation support block 110 on the tooling platform 101 can be synchronously adjusted with the pressing head seat 107 and the edge portion pressing head 106, and the edge portion anti-deformation support is compatible with the bottom plate 502 having different diameters.

[0078] In the case where the T-shaped sliding groove is formed in the edge portion pressing mechanism of the bottom plate, the anti-deformation support block 110 can slide along the T-shaped sliding groove. On the other hand, when the bottom plate 502 is clamped by the non-deformation positioning, since the top surface of the anti-deformation support block 110 is lower than the support surface in the non-deformation support structure (for example, the top surface of the non-deformation support block 104), even if the anti-deformation support block 110 is located below the bottom plate 502, it will not affect the normal execution of the non-deformation positioning.

[0079] Before positioning and clamping the bottom plate 502, the bottom plate 502 can be pre-positioned by the bottom plate pre-positioning pins 111 arranged on the tooling platform 101 penetrating the process holes of the bottom plate 502, and after pre-positioning, the bottom plate pre-positioning pins 111 can prevent the bottom plate 502 from rotating on the tooling platform 101, so the number of bottom plate pre-positioning pins 111 is at least two.

[0080] In order to be compatible with the pre-positioning of different models of bottom plates 502, the number of bottom plate pre-positioning pins 111 can be set to no less than three, and at least part of the bottom plate pre-positioning pins 111 are detachably connected with the tooling platform 101. In this way, when pre-positioning a certain model of bottom plate 502, the bottom plate pre-positioning pins 111 that hinder the placement of the bottom plate 502 can be temporarily removed.

[0081] The accompanying tooling 100 has mobility, including the overall movement of the positioning and clamped turntable structure 500 (including the bottom plate 502, the welding assembly composed of the stand plate 501 and the bottom plate 502, and the welding assembly composed of the stand plate 501, the bottom plate 502 and the shaft sleeve 503, etc.). Therefore, the accompanying tooling 100 can serve as a transfer carrier for the pipeline production of the turntable structure 500.

[0082] Reference Figures 4 to 7The traveling tool 100 can include a tool outer positioning structure arranged at the bottom of the tool platform 101, which can be used to position the tool platform 101 on the transfer device 400 (for example, an RGV trolley) and / or a welding operation base station in an outer manner, wherein the welding operation base station includes the manual welding operation base station 200 and the automatic welding operation base station 300 (for example, a base station in a welding positioner).

[0083] During the welding process, the base plate 502 can be transferred to different welding operation base stations by the transfer device 400 after being positioned and clamped on the traveling tool 100, while the traveling tool 100 provides a positioning reference for the positioning of the base plate 502 and the transfer device 400 or the welding operation base station, improves the consistency of the manufacturing precision of the rotary table structure 500, and the selectively usable multiple welding operation base stations are beneficial to alleviate the pressure of each base station and avoid the aggravation of wear caused by the frequent use of a single base station.

[0084] As an example, the tool outer positioning structure can include a tool guide pin hole 112, a tool zero point pin 113, a tool taper hole positioning block 114, and a tool pressure joint block 115, and the arrangement mode is referred to Figure 4 The transfer device 400 can include a device taper pin positioning block 401 and a device pressure joint block 402, and the arrangement mode is referred to Figure 5 The manual welding operation base station 200 can include a base station taper pin positioning block 201 and a base station pressure joint block 202, and the arrangement mode is referred to Figure 6 The automatic welding operation base station 300 can include a base station guide pin 301, a base station zero point chuck 302, and a base station conductive column 303, and the arrangement mode is referred to Figure 7 .

[0085] When positioning the tool platform 101 and the transfer device 400, the two tool taper hole positioning blocks 114 are respectively matched and installed with the two device taper pin positioning blocks 401 for positioning, and the four tool pressure joint blocks 115 are respectively matched and pressed with the four device pressure joint blocks 402 to ensure the connection stability of the tool platform 101 and the transfer device 400.

[0086] When positioning the tool platform 101 and the manual welding operation base station 200, the two tool taper hole positioning blocks 114 are respectively matched and installed with the two base station taper pin positioning blocks 201 for positioning, and the four tool pressure joint blocks 115 are respectively matched and pressed with the four base station pressure joint blocks 202 to ensure the connection stability of the tool platform 101 and the manual welding operation base station 200.

[0087] When positioning the tool platform 101 and the automatic welding operation base station 300, due to the higher positioning accuracy requirement, a coarse positioning plus fine positioning mode can be used.

[0088] Specifically, the rough positioning of the tooling platform 101 and the automatic welding work base 300 is achieved by matching and installing the two tooling guide pin holes 112 with the two base guide pins 301 respectively. And the fine positioning of the tooling platform 101 and the automatic welding work base 300 is achieved by matching and installing the eight tooling zero point pins 113 with the eight base zero point chucks 302 respectively.

[0089] It should be noted that the zero point pin 113 and the base zero point chuck 302 constitute a zero point positioning system, which can lock the tooling platform 101 and ensure that the tooling platform 101 will not loosen during welding displacement.

[0090] On the other hand, during welding, the base conductive column 303 is in contact with the bottom surface of the tooling platform 101, and can conduct electricity. The base conductive column 303 is usually equipped with a spring to ensure good contact between the base conductive column 303 and the bottom surface of the tooling platform 101, which can avoid damage to the zero point positioning system or the guide pin positioning system and affect the positioning accuracy.

[0091] The second exemplary embodiment of the present application also provides an auxiliary welding system, which includes the above-mentioned tooling platform 100 with the tooling external positioning structure at the bottom, the transfer equipment 400, and a plurality of welding work bases.

[0092] Each welding work base is provided with a base external positioning structure for detachable cooperation with the tooling external positioning structure, such as the base taper pin positioning block 201 and the base pressure contact block 202 in the manual welding work base 200 described above, or the base guide pin 301, the base zero point chuck 302, and the base conductive column 303 in the automatic welding work base 300.

[0093] The transfer equipment 400 is provided with an equipment external positioning structure for detachable cooperation with the tooling external positioning structure, such as the equipment taper pin positioning block 401 and the equipment pressure contact block 402 described above. By using the transfer equipment 400, the tooling platform 100 can be transferred to any welding work base for welding work.
