Description

Technical Field

[0001] This utility model belongs to the field of automotive welding fixture technology. Specifically, this utility model relates to a quick-turning platform for automotive welding fixtures. Background Technology

[0002] In the body-in-white welding operations in the prototype workshop, due to the structural design characteristics of the body, the top welding points are often located at a high position, making it difficult for operators to directly access them for welding. To solve this problem, existing technologies typically place a movable platform on the welding fixture, allowing workers to stand and raise their operating height to complete the welding work on the top welding points. However, during the welding process, the movable platform lacks a stable connection structure with the fixture, relying solely on its own placement on the fixture. When workers perform welding operations on the platform, body movement or exertion can easily cause the platform to become unbalanced, posing a safety hazard of tipping over. This not only may affect the normal progress of the welding operation but also threatens the personal safety of the operators. Furthermore, it requires removal each time it is used, making it inconvenient to use.

[0003] Chinese patent (publication number: 203114148U) discloses a mobile ladder comprising a platform, movable steps, support legs, a lifting step, a brake, and a set of casters. The ladder has a welded pipe frame, with fixed casters installed at the rear of the lower part. Brakes are mounted on the support legs. The platform is located at the top of the ladder and connected to the movable steps. Support legs are located below the movable steps. A set of casters is located below the braking mechanism, and a fixed set of casters is located at the lower front end of the ladder. This structure lacks a stable connection structure and is prone to causing danger. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a fast-flipping platform for automotive welding fixtures that is stable and does not require frequent handling. To achieve the above objective, the technical solution adopted by this utility model is as follows: a fast-flipping platform for automotive welding fixtures, comprising a fixture body, a flipping structure provided on the fixture body, and a support platform provided on the flipping structure.

[0005] The flipping structure includes a first support base and a second support base, which are disposed at both ends of the fixture body. The first support base is connected to one end of the support platform via a rotating shaft, and the other end of the support platform is connected to the second support base.

[0006] The first support base includes a first pad and a first support plate. The first pad is connected to the fixture body, and the other end of the first pad is connected to the support platform pivot. The first support plate is disposed at the bottom of the support platform and abuts against the support platform.

[0007] The second support base includes a second support plate, which abuts against the support platform.

[0008] The support platform has a first connecting hole, and the second support plate has a second connecting hole. A first pin is provided in the first connecting hole and the second connecting hole.

[0009] The fixture body includes a first fixed column and a second fixed column, which are spaced apart. A first support base is disposed on the first fixed column, and a second support base is disposed on the second fixed column. A third fixed base is disposed on the second fixed column, and the third fixed base is connected to the support platform.

[0010] The third fixing base includes a second pad and a fixing plate. The second pad is connected to the first fixing column. A connecting plate is provided on the second pad. A first fixing hole is provided on the connecting plate. A second fixing hole is provided at the end of the support platform. A second pin is provided in the first fixing hole and the second fixing hole.

[0011] The first support plate has an L-shaped structure and a first reinforcing plate is provided on the first support plate. The second support plate has an L-shaped structure and a second reinforcing plate is provided on the second support plate.

[0012] The support platform is a flat plate with a hollow interior, and structural reinforcing plates are spaced apart inside the support platform.

[0013] The technical advantages of this invention are as follows: When welding operations require the use of a support platform, the operator rotates the vertical support platform downwards around the pivot connecting the first support base and the support platform until the support platform is horizontal. At this point, the first and second support plates abut against the bottom of the support platform, providing stable support. Subsequently, the first pin is inserted into the first connecting hole of the support platform and the second connecting hole of the second support plate to fix the support platform to the second support base, preventing the support platform from shifting or wobbling when the operator stands. The operator can then safely stand on the support platform to weld the weld points on the top of the vehicle body.

[0014] When the welding operation is completed and the support platform is no longer needed, the operator pulls out the first pin to release the support platform from the second support base, and rotates the support platform upwards around the axis of rotation of the first support base to a vertical position. Next, the second pin is inserted into the first fixing hole of the connecting plate and the second fixing hole at the end of the support platform, fixing the support platform to the third fixing base and ensuring that the support platform is stably placed in a vertical position without interfering with the operator's other work.

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0021] like Figures 1-3 As shown, a quick-turning platform for an automotive welding fixture includes a fixture body 1, a turning structure 2 on the fixture body 1, and a support platform 3 on the turning structure 2. The fixture body 1 provides a stable support base for the turning structure 2 and the support platform 3, and serves as the carrier for mounting the turning structure 2 and the support platform 3. The support platform 3 is connected to the turning structure 2, and the setting of the turning structure 2 allows the support platform 3 to rotate. When needed, the support platform 3 is turned to a horizontal position and then fixed, allowing the operator to stand on the support platform 3 to weld the weld points on the top of the vehicle body. When the support platform 3 is not needed, it is turned to a vertical position without affecting the operator's work.

[0022] The flipping structure 2 includes a first support base 21 and a second support base 22, which are located at both ends of the fixture body 1. The first support base 21 is pivotally connected to one end of the support platform 3, and the other end of the support platform 3 is connected to the second support base 22. The first support base 21 and the second support base 22 are connected at both ends of the fixture body 1. When the support platform 3 is placed horizontally, the first support base 21 supports the support platform 3. The pivotal connection between the first support base 21 and one end of the support platform 3 enables the flipping function of the support platform 3, while also providing support when the support platform 3 is in a horizontal position. When the support platform 3 is not needed, it can be flipped to a vertical position without affecting the operator's work.

[0023] The first support base 21 includes a first pad 211 and a first support plate 212. The first pad 211 is connected to the fixture body 1, and the other end of the first pad 211 is connected to the pivot of the support platform 3. The first support plate 212 is disposed at the bottom of the support platform 3 and abuts against the support platform 3. The first pad 211 is bolted to the fixture body 1, and the other end of the first pad 211 is connected to the pivot of the support platform 3. The first support plate 212 is welded to the first pad 211 and abuts against the bottom of the support platform 3. The first pad 211 increases the connection area with the fixture body 1, making the connection more stable; the first support plate 212 is connected to the first pad 211, and the first support plate 212 abuts against the bottom of the support platform 3, ensuring that the support platform will not sink when bearing load, thus enhancing the stability of the support.

[0024] The second support base 22 includes a second support plate 221, which abuts against the support platform 3. The second support plate 221 is located at the other end of the clamp body 1. When the support platform 3 is placed horizontally, the second support plate 221 provides support for the support platform 3, thereby enhancing the stability of the support platform 3 when it is placed horizontally and preventing the support platform 3 from shaking.

[0025] The support platform 3 has a first connecting hole, and the second support plate 221 has a second connecting hole. A first pin 4 is installed in both the first and second connecting holes. The support platform 3 and the second support plate 221 are connected by the first pin 4. The first pin 4 connection facilitates disassembly and fixation, which can reduce the risk of the support platform 3 shifting due to instability when the operator is standing on it.

[0026] The fixture body 1 includes a first fixed post 101 and a second fixed post 102, which are spaced apart. A first support base 21 is mounted on the first fixed post 101, and a second support base 22 is mounted on the second fixed post 102. A third fixed base 5 is mounted on the second fixed post 102 and connected to the support platform 3. The spaced arrangement of the first fixed post 101 and the second fixed post 102 ensures balanced force distribution between the flipping structure 2 and the support platform 3, guaranteeing stability during operation. The first fixed post 101 and the second fixed post 102 are bolted to the working base plate.

[0027] The third fixed base 5 includes a second pad 501 and a fixed plate 502. The second pad 501 is connected to the first fixed post 101. A connecting plate 503 is provided on the second pad 501, and a first fixing hole is provided on the connecting plate 503. A second fixing hole is provided at the end of the support platform 3. A second pin 6 is provided in the first fixing hole and the second fixing hole. The second pad 501 is bolted to the second fixed post 102. The connecting plate 503 is welded to the second pad 501. The end of the support platform 3 is connected to the connecting plate 503 through the second pin 6, which fixes the support platform 3 and ensures that the support platform 3 is stable when flipped to the vertical position, without affecting the operator's use.

[0028] The first support plate 212 has an L-shaped structure and is equipped with a first reinforcing plate 7. The second support plate 221 also has an L-shaped structure and is equipped with a second reinforcing plate 8. The vertical portion of the L-shaped structure of the first support plate 212 is connected to the first pad 211, while the horizontal portion provides vertical support to the bottom of the support platform 3, bearing the vertical load of the support platform 3 and being fixed to the first pad 211 via its vertical portion. The first reinforcing plate 7 is welded to the first support plate 212, further enhancing the overall rigidity of the first support plate 212 by filling the stress concentration area of ​​the L-shaped structure. The horizontal portion of the L-shaped structure of the second support plate 221 abuts against the bottom of the support platform 3, providing support when the support platform 3 is placed horizontally. The vertical portion is connected to the second fixed column 102. The second reinforcing plate 8 effectively resists the transmitted force of the support platform 3, preventing structural fatigue or deformation of the second support plate 221 due to long-term stress, and ensuring the durability of the supporting performance of the second support plate 221.

[0029] The support platform 3 is a flat plate with a hollow interior. Reinforcing structural plates 9 are spaced within the support platform 3. The flat plate structure of the support platform 3 provides a smooth operating surface, meeting the needs of operators for standing and workpiece placement. The hollow interior reduces the weight of the support platform 3, decreasing manpower consumption during flipping operations and reducing material costs.

[0030] The structural reinforcing plates 9 spaced apart inside the support platform 3 evenly transfer the load on the surface of the support platform 3 to the edge support parts, effectively resisting the bending deformation of the support platform 3 caused by its own weight or external load, and ensuring the flatness and structural strength of the support platform 3.

[0031] The role and effect of the embodiments

[0032] When welding is required using the support platform 3, the operator rotates the vertical support platform 3 downwards around the pivot connecting the first support base 21 and the support platform 3 until the support platform 3 is horizontal. At this time, the first support plate 212 and the second support plate 221 abut against the bottom of the support platform 3, providing stable support for the support platform 3. Subsequently, the first pin 4 is inserted into the first connecting hole of the support platform 3 and the second connecting hole of the second support plate 221 to fix the support platform 3 to the second support base 22, preventing the support platform 3 from shifting or shaking when the operator stands. The operator can then safely stand on the support platform 3 to weld the weld points on the top of the vehicle body.

[0033] When the welding operation is completed and the support platform 3 is no longer needed, the operator pulls out the first pin 4 to release the fixation between the support platform 3 and the second support base 22, and rotates the support platform 3 upwards around the axis of rotation of the first support base 21 to a vertical position. Next, the second pin 6 is inserted into the first fixing hole of the connecting plate 503 and the second fixing hole at the end of the support platform 3, fixing the support platform 3 to the third fixing base 5, ensuring that the support platform 3 is stably placed in a vertical position and does not interfere with the operator's other work.
