Description

Technical Field

[0001] This utility model relates to the field of standard section production technology, specifically to a sheet standard section welding unit. Background Technology

[0002] Both frame-type and plate-type standard sections are components of tower cranes, primarily used to support and connect the main structure of the tower crane, ensuring its stability and load-bearing capacity. The height of the tower crane is adjusted by adding or removing standard sections. A plate-type standard section is assembled and welded from two parallel, spaced-apart main spiral tubes and several parallel, spaced-apart main plates between the two main spiral tubes. The two ends of the main plates are fixed to the corresponding main spiral tubes, and bent plates are fixedly installed between the main plates and the main spiral tubes to improve installation stability.

[0003] Generally, standard sheet sections are welded together using appropriate welding equipment. After the top section is welded, the welding equipment drives the standard sheet section to rotate for back-side welding to enhance the stability of the connection between the parts. Throughout the entire process, the loading robot must wait for the standard sheet section to be welded and removed from the welding equipment before it can load another section, resulting in stagnant processing efficiency and significant inconvenience.

[0004] Therefore, the research objective of this utility model is to design a sheet-type standard section welding unit that, while ensuring the stability of welding and flipping, adds a double-head tooling to enable simultaneous feeding and welding, thereby improving processing efficiency and effectively eliminating vibrations transmitted from the welding station to the feeding station, thus avoiding adverse effects on feeding. Utility Model Content

[0005] In view of the technical problems existing in the prior art, the present invention provides a sheet-type standard section welding unit, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A sheet-type standard section welding unit, comprising:

[0008] The double-headed fixture has a material loading station and a welding station on its front and rear sides, respectively.

[0009] The handling robot loads the standard sheet components onto the loading station of the double-headed tooling;

[0010] A welding robot is installed on the welding station of the double-headed tooling and is used to weld and connect the components of the sheet-like standard section that are assembled and fixed on the welding station.

[0011] The double-head fixture includes:

[0012] The rotating frame is driven to rotate by a corresponding first electric motor and is supported on a set of first bearing seats;

[0013] A set of rotating crossbeams are rotatably mounted on both sides of the rotating upright via support arm assemblies fixed to the rotating upright. When the rotating crossbeams rotate with the rotating upright from the loading station side to the welding station side, the rotating crossbeams rotate in the opposite direction and keep their front side facing upward. The support arm assembly includes support arms fixedly mounted on the left and right sides of the rotating upright via corresponding connecting components. The connecting components are used to connect the rotating upright and the support arms and to reduce the vibration transmitted from the welding station to the loading station.

[0014] The connecting assembly includes two locking plates that are respectively fixedly welded to the support arm and the rotating frame. The two locking plates are connected by bolts to fix the support arm laterally on the rotating frame.

[0015] The connecting assembly also includes a connecting member installed between two locking plates with an inverted H-shaped longitudinal section. The connecting member consists of a central vertical plate and a horizontal plate integrally formed and fixed at the upper and lower ends of the vertical plate. The two locking plates are respectively embedded in the grooves formed by the vertical plate and the horizontal plate, and are locked and fixed by bolts that pass through the locking plates and the vertical plate respectively.

[0016] The upright plate is provided with a number of horizontally arranged through holes. The two ends of the through holes are connected to the two sides of the upright plate. The vibration generated during the welding process at the welding station is transmitted to the through holes and forms a resonance energy dissipation and vibration reduction in the through holes.

[0017] Some or all of the through holes are welded to corresponding sealing plates at both ends. The through holes between the sealing plates are respectively filled with a number of corresponding damping particles for vibration reduction, and the through holes filled with damping particles and the through holes not filled with damping particles are arranged alternately.

[0018] The connector is made of engineering plastic.

[0019] The rotating crossbeam is rotatably mounted on the support arm assembly via a corresponding second bearing seat, and is driven to rotate by a second motor fixed to any one of the support arms.

[0020] Both of the rotating crossbeams are provided with positioning components on their front sides for limiting and fixing the corresponding parts of the plate-type standard section.

[0021] Advantages of this utility model:

[0022] 1) This utility model, while ensuring the stability of welding and flipping, adds a double-headed fixture with two rotating crossbeams at the front and rear. This allows the rotating crossbeams on both sides to perform loading and welding simultaneously, thereby improving processing efficiency. After the welding station is completed, the first motor drives the rotating upright to rotate and rotates the two rotating crossbeams to swap positions. The welded standard section is then rotated to the loading station for unloading, while the unwelded standard section is rotated to the welding station for further welding. During the swapping of the two rotating crossbeams, the second motor drives each rotating crossbeam to rotate in the opposite direction, keeping the front side facing upwards. This ensures that the parts fixed on the rotating crossbeams do not shift, thus ensuring the quality of the welding.

[0023] 2) Welding generates vibrations that are transmitted through the rotating upright to the rotating crossbeam at the loading station, and then to the sheet-like standard section components mounted on the crossbeam. Even with positioning components, these components are prone to shifting due to vibration. Even slight shifts can affect the weld stability and quality between the various parts, thus impacting the production quality of the sheet-like standard section. Therefore, this invention further incorporates connecting components between the rotating upright and the support arm that mounts the rotating crossbeam. These components not only stably connect the rotating upright and the support arm but also reduce the vibration transmitted from the welding station to the loading station, effectively eliminating the vibration and preventing shifts between components caused by welding vibration, thus ensuring weld quality.

[0024] 3) The connector of this utility model is an inverted H-shaped structure consisting of a central upright plate and horizontal plates integrally formed and fixed at the upper and lower ends of the upright plate. It not only embeds and limits the locking plates of the welding rotating upright and the support arm into the groove between the connectors, but also connects and fixes them with bolts; in addition, the upright plate is provided with a number of through holes in the horizontal direction, and the two ends of the through holes are connected to the two sides of the upright plate. By transmitting the vibration generated during the welding process at the welding station to the through holes, the vibration forms a resonance energy dissipation and vibration reduction in the through holes.

[0025] 4) In addition to vibration energy dissipation and vibration reduction through the formation of vibration energy dissipation in the pores, this utility model can also effectively reduce vibration by filling all or part of the through holes with damping particles for vibration reduction and sealing both ends, thereby effectively avoiding the adverse effects of vibration during welding at the welding station on the displacement of parts loaded at the loading station.

Detailed Implementation

[0032] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0033] Example 1

[0034] refer to Figure 1-3 A standard section welding unit, comprising:

[0035] The double-headed fixture 1 has a material loading station 101 and a welding station 102 on its front and rear sides, respectively.

[0036] The handling robot 2 loads the standard sheet components onto the loading station 101 of the double-head tooling 1;

[0037] A welding robot (not labeled) is installed on the welding station 102 of the double-head tooling 1 and is used to weld and connect the components of the sheet standard section assembled and fixed on the welding station 102.

[0038] The double-head tooling 1 includes:

[0039] The rotating frame 3 is driven to rotate by a corresponding first electric motor and is supported on a set of first bearing seats 4;

[0040] A set of rotating crossbeams 5 are rotatably mounted on both sides of the rotating upright 3 via support arm assemblies fixed to the rotating upright 3. When the rotating crossbeams 5 rotate with the rotating upright 3 from the loading station 101 side to the welding station 102 side, the rotating crossbeams 5 rotate in the opposite direction and keep their front side facing upward. The support arm assembly includes support arms 6 fixedly mounted on the left and right sides of the rotating upright 3 via corresponding connecting components. The connecting components are used to connect the rotating upright 3 and the support arms 6 and to reduce the vibration transmitted from the welding station 102 to the loading station 101.

[0041] This invention, while ensuring welding and flipping stability, adds a double-headed fixture 1 with two rotating crossbeams 5 at the front and rear. This allows the rotating crossbeams 5 on both sides to simultaneously perform loading and welding, thereby improving processing efficiency. After the welding station 102 is completed, the first motor drives the rotating upright 3 to rotate and rotate the two rotating crossbeams 5 to swap positions. The welded standard sheet section is then transferred to the loading station 101 for unloading, while the unwelded standard sheet section is transferred to the welding station 102 for further welding. During the swapping of the two rotating crossbeams 5, the second motor drives each rotating crossbeam 5 to rotate in the opposite direction, keeping the front side facing upwards. This ensures that the parts fixed on the rotating crossbeams 5 do not shift, thus ensuring the quality of the welding.

[0042] Welding generates vibrations that are transmitted through the rotating upright 3 to the rotating crossbeam 5 at the loading station 101, and then to the sheet-like standard section components mounted on the crossbeam 5. Even though the components are fixed by the positioning assembly 11, the vibrations can easily cause them to shift. Even a slight shift can affect the welding stability and quality between the various parts, thus impacting the production quality of the sheet-like standard section. Therefore, this invention further installs a corresponding connecting assembly between the rotating upright 3 and the support arm 6 that mounts the rotating crossbeam 5. This assembly not only stably connects the rotating upright 3 and the support arm 6 but also reduces the vibrations transmitted from the welding station 102 to the loading station 101, effectively eliminating the vibrations and preventing shifts between parts caused by welding vibrations, thus ensuring welding quality.

[0043] The connecting assembly includes two locking plates 7 that are respectively fixedly welded to the support arm 6 and the rotating frame 3. The two locking plates 7 are connected by bolts to fix the support arm 6 horizontally on the rotating frame 3.

[0044] The connecting assembly also includes a connecting member 8 installed between the two locking plates 7 and having an inverted H-shaped longitudinal section. The connecting member 8 is composed of a central vertical plate 801 and a horizontal plate 802 integrally formed and fixed at the upper and lower ends of the vertical plate 801. The two locking plates 7 are respectively embedded in the grooves formed by the vertical plate 801 and the horizontal plate 802, and are locked and fixed by bolts that pass through the locking plates 7 and the vertical plate 801 respectively.

[0045] The upright plate 801 is provided with a number of horizontally arranged through holes 8011. The two ends of the through holes 8011 are connected to the two sides of the upright plate 801. The vibration generated during the welding process of the welding station 102 is transmitted to the through holes 8011 and forms a resonance energy dissipation and vibration reduction in the through holes 8011.

[0046] The connector 8 is made of engineering plastic.

[0047] The connector 8 of this utility model is an inverted H-shaped structure consisting of a central upright plate 801 and horizontal plates 802 integrally formed and fixed at the upper and lower ends of the upright plate 801. It not only embeds and limits the locking plates of the welding rotating frame 3 and the support arm 6 into the groove of the connector 8, but also connects and fixes them with bolts; in addition, the upright plate 801 is provided with a number of through holes 8011 in the horizontal direction. The two ends of the through holes 8011 are connected to the two sides of the upright plate 801. By transmitting the vibration generated during the welding process of the welding station 102 to the through holes 8011, the vibration forms a resonance energy dissipation and vibration reduction in the through holes 8011.

[0048] The rotating crossbeam 5 is rotatably mounted on the support arm assembly via a corresponding second bearing seat, and is driven to rotate by a second motor fixed on any one of the support arms 6.

[0049] Both of the rotating crossbeams 5 are provided with positioning components 11 on their front sides for limiting and fixing the corresponding parts of the plate standard section. The positioning components 11 can be commercially available and can be used to fix and limit the inclined web bar, main rotating tube, main board, and bending plate that are gripped by the welding robot and placed on the rotating crossbeam 5 at the loading station 101.

[0050] Example 2

[0051] refer to Figure 4-5 The difference between this embodiment and embodiment one is that: some or all of the through holes 8011 are respectively welded with corresponding sealing plates 9, and the through holes 8011 between the sealing plates 9 are respectively compacted and filled with a number of corresponding damping particles 10 for vibration reduction, and the through holes 8011 filled with damping particles 10 and the through holes 8011 not filled with damping particles 10 are alternately arranged.

[0052] In addition to vibration energy dissipation and vibration reduction through the formation of vibration energy dissipation in the pores, this utility model can also effectively reduce vibration by filling all or part of the through hole 8011 with damping particles 10 for vibration reduction and sealing both ends, thereby effectively avoiding the adverse effects of vibration during welding at the welding station 102 on the parts loaded at the loading station 101.

[0053] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.

[0054] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
