Description

Technical Field

[0001] This utility model relates to the field of welding positioning fixture technology, specifically to a fixture support base that can cope with various loads and variable installation cross-sections. Background Technology

[0002] Sheet metal parts in the automotive industry are often large in size and thin in thickness. Therefore, during welding, cylinders need to be installed using tooling support seats to clamp, position, and support automotive sheet metal parts.

[0003] Traditional tooling support bases mostly adopt a split welding design. Split welding support bases are spliced ​​together from components such as base and column. Stress concentration is prone to occur at the connection points. When subjected to high-frequency impact loads, weld cracks are likely to occur. In addition, the spliced ​​structure is heavy, consumes a lot of energy, and has poor versatility.

[0004] How to solve the above-mentioned technical problems is something that those skilled in the art need to consider. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a tooling support base that can cope with various loads and variable installation cross sections.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A tooling support for handling various loads and variable installation cross-sections includes a base, a column, and a cylinder mounting block integrally formed by extrusion. The width surface of the column is a vertical surface with threaded mounting holes. The thickness surface of the column is a bent surface with non-standard mounting holes. The horizontal or vertical surface of the cylinder mounting block has locating pin holes and cylinder connection holes.

[0007] The beneficial effects of this utility model are: 1. The extrusion molding process creates a seamless integrated structure for the base, column, and cylinder mounting block. Compared to traditional welding or splicing structures, this structure avoids stress concentration at the connection points, resulting in stronger overall structural integrity. It can more evenly distribute various loads such as clamping force and part weight during automotive sheet metal welding, significantly improving the support's resistance to deformation and load-bearing strength to meet the needs of various loads. At the same time, it reduces the need for individual processing, splicing, and post-weld treatment of parts, shortening the production cycle and improving material utilization.

[0008] 2. Locating pin holes and cylinder connection holes are set on the horizontal or vertical surfaces of the cylinder mounting block. While achieving precise positioning of the cylinder, it breaks the limitation of a single installation direction. It can flexibly select the cylinder installation posture according to the tooling layout, cylinder model and sheet metal clamping requirements, greatly improving the flexibility of tooling design and providing basic adaptation conditions for variable installation cross-section.

[0009] Furthermore, the base and the column are arranged in a T-shape, which increases the contact area between the base and the tooling platform and significantly improves the overall stability of the support. Especially when subjected to eccentric loads, the torque can be balanced by the extended ends of the base, preventing the support from tilting or tipping over.

[0010] Furthermore, the base and the column are arranged in an L-shape, the base can stably fit the tooling platform, and the column provides vertical support. The structure is compact and occupies little tooling space.

[0011] Furthermore, the base has extension plates extending from the columns on one or both sides, and these extension plates are provided with locating pin holes and threaded connection holes. The locating pin holes and threaded connection holes enable the base to be precisely installed onto the tooling platform.

[0012] Furthermore, multiple threaded mounting holes on the width surface of the column are evenly distributed along the height direction. These threaded mounting holes serve as a direct indicator for part identification, allowing workers to quickly determine the specifications and model of the support base by the number of holes, reducing part identification errors and improving the efficiency of tooling assembly and maintenance. Simultaneously, the evenly distributed holes ensure that the load is evenly transmitted along the column's height, avoiding weak areas in the column's strength caused by densely packed holes in certain areas, and ensuring that the column maintains stable performance under load at different heights.

[0013] Furthermore, a support reinforcement plate is installed on the lower part of the column's width surface through threaded mounting holes. The lower part of the column is the load concentration area connected to the base. After the reinforcement plate is fixed through the threaded mounting holes, the cross-sectional thickness and rigidity of this area can be increased, effectively resisting the deformation of the column caused by bending loads.

[0014] Furthermore, the thickness surface of the column is a bent surface with a bend line. This bend line divides the column into an upper column and a lower column. The thickness surface of the upper column is a vertical surface with locating pin holes and non-standard component mounting holes. The thickness surface of the lower column is an inclined surface. The locating pin holes and non-standard component mounting holes on the vertical surface of the upper column ensure precise positioning of standard / non-standard components, while the inclined surface of the lower column maximizes the overall support capacity and enhances its performance in handling various loads without increasing the column's overall weight.

[0015] Furthermore, a stiffening rib is provided between the cylinder mounting block and the column. The cylinder mounting block is located on the top of the column, parallel or perpendicular to the base extension plate, further realizing a variable installation cross section; the stiffening rib can form a triangular stable support structure between the cylinder mounting block and the column, effectively dispersing the lateral impact force generated when the cylinder is working, and preventing the cylinder mounting block from shifting or breaking due to excessive force.

[0016] Furthermore, the cylinder mounting block is equipped with a support plate on top, and the support plate has non-standard mounting holes. The support plate expands the support area of ​​the cylinder mounting block, and can directly support larger sheet metal parts or blocks, avoiding localized deformation of sheet metal parts due to insufficient support area.

[0017] Furthermore, a wire threaded sleeve is provided inside the cylinder connection hole. The wire threaded sleeve is made of high-strength steel wire and can be embedded in the internal thread of the cylinder connection hole to form a wear-resistant and corrosion-resistant thread interface, avoiding thread wear caused by frequent cylinder disassembly.

Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0024] Example 1 like Figure 1 , Figure 2 As shown, this embodiment provides a tooling support for handling various loads and variable installation cross-sections, including a base 1, a column 2, and a cylinder mounting block 3 integrally formed by extrusion. The extrusion integral forming process creates a seamless overall structure for the base 1, column 2, and cylinder mounting block 3. Compared with traditional welding or splicing structures, this avoids stress concentration at the connection points, resulting in stronger overall structural integrity. It can more evenly distribute various loads such as clamping force and part weight during automotive sheet metal welding, significantly improving the support's resistance to deformation and load-bearing strength to meet the needs of handling various loads. At the same time, it reduces the need for individual processing, splicing, and post-weld treatment of parts, shortening the production cycle and improving material utilization.

[0025] Specifically: The base 1 and the column 2 are arranged in a T-shape, meaning that extension plates 11 extending relative to the column 2 are formed on both sides of the base 1; the extension plates 11 are provided with first positioning pin holes 12 and threaded connection holes 13. The T-shape structure increases the contact area between the base and the tooling platform, significantly improving the overall stability of the support, especially when subjected to eccentric loads (such as the offset of the center of gravity of sheet metal parts), the torque can be balanced by the two ends of the extended base, preventing the support from tilting or tipping over. The positioning pin holes and threaded connection holes allow the base to be accurately installed onto the tooling platform.

[0026] The column 2 has a rectangular cross-section. The side corresponding to the long side of the cross-section (the side parallel to the length direction of the base 1) is the width surface 21, and the side corresponding to the short side of the cross-section (the side perpendicular to the length direction of the base 1) is the thickness surface 22. Wherein: The width surface 21 of the column 2 is a vertical surface, and threaded mounting holes 211 are provided on the width surface 21. Multiple threaded mounting holes 211 are evenly distributed along the height direction (the distance between two adjacent threaded mounting holes 211 is equal). The vertical width surface 21 provides a stable machining reference for the threaded mounting holes 211; and the multiple threaded mounting holes 211 can serve as a visual identifier for part identification. Workers can quickly determine the specification and model of the support base (such as a short column suitable for small sheet metal parts, a long column suitable for large sheet metal parts) by the number of holes, reducing part identification errors and improving the efficiency of tooling assembly and maintenance. At the same time, the evenly distributed holes ensure that the load is evenly transmitted along the height direction of the column 2, avoiding weak areas of the column 2 caused by dense local holes, and ensuring that the column 2 can maintain stable performance when bearing loads at different heights.

[0027] The thickness surface 22 of the column 2 is a bent surface, and a bending line 221 is provided on the thickness surface 22. This bending line 221 divides the column into an upper column 222 and a lower column 223. The thickness surface of the upper column 222 is a vertical surface, and a second positioning pin hole 2221 and a first non-standard part mounting hole 2222 are provided on this vertical surface. The thickness surface of the lower column 223 is an inclined surface. The second positioning pin 2221 and the first non-standard part mounting hole 2222 on the vertical surface of the upper column 222 can maintain accurate positioning of standard / non-standard parts. The inclined surface of the lower column 223 can increase the moment of inertia of the column 2 section, improve the bending stiffness of the column 2, and maximize the overall support capacity without increasing the mass of the column 2, thus strengthening its performance in coping with various loads. When support bases of different heights are required, such as Figure 2 As shown, the lower column 223 has a fixed height and maintains an inclined surface structure to prevent the overall center of gravity of the column 2 from shifting due to the adjustment of the height of the lower column 223, which could lead to the tilting of the support or torque imbalance when bearing load. The height of the upper column 222 can be flexibly lengthened or shortened according to the overall height requirements of the support. Its vertical surface structure and hole distribution are consistent, which can continue the original load transmission path and ensure that the weight of the sheet metal parts, the cylinder clamping force and other loads can be evenly distributed at different heights, avoiding local stress concentration due to height adjustment. Adjusting only the height of the upper column 222 can reduce the amount of processing and the difficulty of processing. When the upper column 222 is lengthened, it can be achieved by connecting with profiles of the same specification and processing the holes in one piece. When the upper column 222 is shortened, only the excess part needs to be cut off as required. The lower column 223 does not need to be modified, which greatly shortens the adjustment cycle. At the same time, the fixed height of the lower column 223 keeps the connection position between the support base and the tooling platform unchanged. After adjustment, there is no need to recalibrate the overall installation position of the support base, reducing tooling debugging time. Especially in the scenario of multiple car models on the same production line, it can quickly switch the support requirements of different heights and improve the flexibility of the production line.

[0028] A stiffening rib 4 is provided between the cylinder mounting block 3 and the column 2. The stiffening rib 4 forms a stable triangular support structure between the cylinder mounting block 3 and the column 2 (a triangle has non-deformable characteristics), effectively dispersing the lateral impact force generated during cylinder operation and preventing the cylinder mounting block 3 from shifting or breaking due to excessive force. Simultaneously, the stiffening rib 4 increases the contact area at the connection point, reducing local stress concentration and increasing the load-bearing capacity of the cylinder mounting block 3, ensuring stable operation of the support under high-frequency, high-load conditions. The cylinder mounting block 3 protrudes towards one side of the column 2 (the side parallel to the base extension plate 11, such as...). Figure 1 (as shown) or one vertical side (such as) Figure 2 As shown in the figure), this setting further enables a variable installation cross section.

[0029] The vertical surface of the cylinder mounting block 3 (e.g.) Figure 1 (as shown) or horizontal plane (such as) Figure 2The cylinder mounting block 3 (as shown) has a third positioning pin hole 31 and a cylinder connection hole 32, with a steel wire threaded sleeve inside the cylinder connection hole 32. The cylinder mounting block 3 has a third positioning pin hole 31 and a cylinder connection hole 32 on its horizontal or vertical surface. This achieves precise cylinder positioning and reliable connection, while breaking the limitation of a single installation direction. It allows for flexible selection of the cylinder installation posture (it can be installed in the X, Y, and Z directions of the production line) according to the tooling layout, cylinder model, and sheet metal clamping requirements, significantly improving the flexibility of tooling design and providing basic adaptation conditions for variable installation cross-sections. The steel wire threaded sleeve inside the cylinder connection hole 32 is made of high-strength steel wire and can be embedded in the internal thread of the cylinder connection hole 32, forming a wear-resistant and corrosion-resistant thread interface, avoiding thread wear caused by frequent cylinder disassembly (such as thread stripping after long-term use). Simultaneously, the steel wire threaded sleeve can compensate for thread machining errors, improve the fitting accuracy of the threaded connection, ensure that the cylinder remains stable and fixed after installation, and reduce positioning deviations caused by loose threads.

[0030] Example 2 It is basically the same as Example 1, except that: like Figure 3 As shown, the base 1 and the column 2 are arranged in an L-shape, that is, an extension plate 11 is formed on one side of the base 1 that extends relative to the column 2. The L-shaped base 1 can stably fit the tooling platform, and the column 2 provides vertical support. The structure is compact and occupies little tooling space. At the same time, the force transmission path of the L-shaped structure is direct (the load of the sheet metal part is transmitted to the base 1 through the column 2, and then distributed to the platform), which reduces energy loss during the load transmission process, improves the bearing efficiency of the support for vertical loads, and is suitable for the welding positioning requirements of small and medium-sized sheet metal parts.

[0031] Example 3 It is basically the same as Example 1, except that: like Figure 4 As shown, the cylinder mounting block 3 has a support plate 33 on its top, and the support plate 33 has a second non-standard mounting hole 331. The support plate 33 expands the support area of ​​the cylinder mounting block 3, and can directly support larger sheet metal parts or blocks, avoiding local pressure deformation of sheet metal parts due to insufficient support area; at the same time, the second non-standard mounting hole 331 on the support plate 33 further breaks the adaptation limitations of standard parts, enabling the support base to meet the variable installation cross-section requirements of more complex sheet metal parts, and improving the versatility of the tooling.

[0032] Example 4 It is basically the same as Example 1, except that: like Figure 5As shown, a support reinforcement plate 5 is installed on the lower part of the width surface 21 of the column 2 through threaded mounting holes 211. The lower part of the column 2 is the load concentration area connected to the base 1. After the reinforcement plate is fixed through the threaded mounting holes 211, it can increase the cross-sectional thickness and rigidity of this area, effectively resisting the deformation of the column 2 caused by bending loads (such as the lateral force when the cylinder clamps, which causes the lower part of the column 2 to bend). At the same time, the reinforcement plate can also disperse the stress at the connection between the base 1 and the column 2, avoiding fatigue cracks at the connection after long-term use, and significantly improving the structural durability of the support.
