Technical Field

[0001] The invention relates to the technical field of vehicle body welding fixtures, and in particular to a quick-insert welding fixing support structure for a vehicle body subassembly welding fixture and a use method thereof. Background Art

[0002] The body sub-assembly welding fixture needs to be installed and used with the support of a fixed support. The fixed support is an important component to ensure the performance of the body sub-assembly welding fixture. Whether its design is reasonable directly affects the welding processing quality of the body sub-assembly welding fixture on the body.

[0003] In the process of subassembling and welding the car body, in order to adapt to car body parts of different sizes and shapes, it is necessary to replace the installation position of the clamp fixing support structure and the clamp fixing support structure of different heights from time to time. However, the existing clamp fixing support structure mostly adopts multiple threaded components and welding platforms for fixed installation. As a result, when the clamp fixing support structure is disassembled and replaced, it is necessary to tighten and loosen numerous threaded components in turn, which makes the operation more troublesome and inconvenient, thereby reducing the disassembly and replacement efficiency of the clamp fixing support structure. Summary of the invention

[0004] In view of this, the present invention provides a quick-insert welding fixing support structure for a vehicle body subassembly welding fixture and a use method thereof, so as to solve the problem of low efficiency in disassembly and replacement of the fixture fixing support structure.

[0005] The technical solution proposed by the present invention is: a quick-insert welding fixed support structure and a use method for a car body assembly welding fixture, specifically comprising: a welding platform, wherein a plurality of fixed supports are distributed at different positions on the top of the welding platform;

[0006] The fixed support as a whole is composed of two symmetrically arranged L-shaped support plates and two horizontal connecting plates welded between the two L-shaped support plates at upper and lower intervals, wherein a plug column is welded downward on the lower horizontal connecting plate; a plurality of slots are provided at different positions on the top of the welding platform, and each plug column is correspondingly plugged and matched with each slot; three vertical positioning plates are welded at intervals in the same direction at the bottom side of the fixed support near each slot, two of which are close to each other and symmetrically arranged on both sides of the slot, and the other is arranged away from the slot, and the part of the plug column protruding from the bottom side of the welding platform is plugged between the two vertical positioning plates arranged close to each other; an F-shaped connector is slidably installed on each of the three vertical positioning plates, and the head end parts of the two horizontal plug rods on each F-shaped connector are slidably matched with each plug column;

[0007] A driving wheel is rotatably mounted below the welding platform near the center position, and a second connecting rod is rotatably connected between the driving wheel and the vertical side rod of each F-shaped connector; a slide plate is welded on the circumferential wheel rim outside the driving wheel; an arc-shaped positioning shaft concentrically arranged with the driving wheel is welded and mounted on the bottom side of the fixed support near the driving wheel, and the slide plate is slidably matched with the arc-shaped positioning shaft through spring pushing.

[0008] Furthermore,

[0009] The top of the welding platform is provided with recessed grooves on both sides of each slot, and the bottom horizontal parts of the two L-shaped support plates on each fixed support are correspondingly plugged into and matched with each two recessed grooves.

[0010] Furthermore,

[0011] Four horizontally arranged hexagonal positioning shafts are welded and hoisted in a cross-shaped symmetrical manner on the outer eaves around the bottom side of the welding platform, and an L-shaped driving rod is slidably mounted on each of the hexagonal positioning shafts.

[0012] Furthermore,

[0013] A cross transmission frame is welded to the bottom end of the driving wheel shaft, and a first connecting rod is rotatably connected between the four ends of the cross transmission frame and the top ends of the four L-shaped driving rod vertical support rod sections.

[0014] Furthermore,

[0015] Four vertical pillars are symmetrically welded on the bottom side of the welding platform near the four corners, and the bottom parts of the four vertical pillars are welded with positioning sleeves. The horizontal rod sections of the four L-shaped driving rods correspond to the four positioning sleeves and slide through them.

[0016] Furthermore,

[0017] The top ends of the four L-shaped driving rods are welded with sliding sleeves, and the four sliding sleeves are correspondingly slidably matched with the four hexagonal positioning shafts.

[0018] Furthermore,

[0019] A welding fixture is fixed between the top ends of the two L-shaped support plates on the fixed support by bolts.

[0020] Further, the following steps are included:

[0021] ① When installing the fixed support, first slide the L-shaped driving rod on the corresponding side toward the positioning sleeve on the corresponding side, driving the spring on the driving wheel and the sliding plate compression arc positioning shaft to twist clockwise;

[0022] ② The driving wheel twists clockwise to drive multiple F-shaped connectors to slide inward and be pulled out synchronously;

The operation is convenient and time-saving, which helps to improve the efficiency of disassembly and replacement of the fixed support.

[0029] 2. When the driving wheel is driven by clockwise rotation, it can simultaneously drive multiple F-shaped connectors to slide inward and withdraw from multiple plug posts, loosening the fixed supports at one time. It is suitable for the use needs of disassembling and replacing all fixed supports, eliminating the trouble of loosening all fixed supports in steps, and helping to improve the efficiency of disassembling and replacing all fixed supports.

[0030] 3. Through the power transmission of multiple second connecting rods and driving wheels, the pushing and holding force of the spring on the arc-shaped positioning shaft can be synchronously transmitted to multiple F-shaped connectors, which allows multiple F-shaped connectors to share a spring on the arc-shaped positioning shaft for pushing and holding positioning, eliminating the need to configure a spring for each F-shaped connector, which helps to simplify the overall structure of the fixed support structure to a certain extent and reduce the overall manufacturing consumables of the fixed support structure.

[0031] 4. The vertical support rod section of the L-shaped driving rod extends downward close to the ground, which allows the L-shaped driving rod to be driven by kicking, so that the extraction and removal of multiple F-shaped connectors can be driven by foot. Compared with manual drive, it does not occupy both hands, so that both hands can be fully freed to cope with the lifting and disassembly of the fixed support, which helps to indirectly further improve the disassembly and replacement efficiency of the fixed support.

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0049] Please refer to Figures 1 to 8 , Embodiment 1:

[0050] The present invention proposes a quick-insert welding fixed support structure for a vehicle body assembly welding fixture, comprising: a welding platform 1, a plurality of fixed supports 2 are distributed at different positions on the top of the welding platform 1;

[0051] The fixed support 2 as a whole is composed of two symmetrically arranged L-shaped support plates and two horizontal connecting plates welded between the two L-shaped support plates at intervals, wherein a plug column 201 is welded downward on the horizontal connecting plate on the lower side; a plurality of slots 105 are provided at different positions on the top of the welding platform 1, and each plug column 201 is correspondingly inserted and matched with each slot 105; three vertical positioning plates 106 are welded at intervals in the same direction at the bottom side of the fixed support 2 near each slot 105, two of which are close to each other and symmetrically arranged on both sides of the slot 105, and the other is arranged away from the slot 105, and the part of the plug column 201 protruding from the bottom side of the welding platform 1 is inserted between the two vertical positioning plates 106 arranged close to each other; an F-shaped connector 107 is slidably installed on every three vertical positioning plates 106, and the head end parts of the two horizontal plug rods on each F-shaped connector 107 are inserted and slidably matched with each plug column 201;

[0052] The F-shaped connector 107 can insert and position the column 201 between two adjacent positions of every three vertical positioning plates 106, and fix the fixed support 2 on the top of the welding platform 1. The F-shaped connector 107 is positioned by spring push. The column 201 can be loosened by simply pulling it inward, and the fixed support 2 can be disassembled and replaced. Compared with the existing technology in which the fixed support 2 is set to be fixed and installed with multiple threaded components, the trouble of tightening and loosening multiple threaded components in turn when disassembling and replacing the fixed support 2 can be eliminated. The operation is convenient and time-saving, which helps to improve the efficiency of disassembly and replacement of the fixed support 2.

[0053] A driving wheel 4 is rotatably mounted near the center of the welding platform 1, and a second connecting rod 403 is rotatably connected between the driving wheel 4 and the vertical side rod of each F-shaped connector 107; a slide plate 404 is welded on the circumferential wheel ring outside the driving wheel 4; an arc-shaped positioning shaft 108 arranged concentrically with the driving wheel 4 is welded and mounted near the bottom side of the fixed support 2, and the slide plate 404 is slidably matched with the arc-shaped positioning shaft 108 through a spring push;

[0054] The driving wheel 4, the plurality of second connecting rods 403 and the plurality of F-shaped connectors 107 are connected together to form a plurality of crank slider mechanisms. Through the plurality of mechanisms, the driving wheel 4 can be rotated clockwise to synchronously pull and drive the plurality of F-shaped connectors 107 to slide inward and be pulled out of the plurality of plug posts 201, thereby releasing the fixed support 2. When the driving wheel 4 is driven to rotate clockwise, the plurality of F-shaped connectors 107 can be synchronously driven to slide inward and be pulled out of the plurality of plug posts 201, thereby releasing the fixed support 2 at one time. This is suitable for the use requirements of disassembling and replacing all the fixed supports 2, eliminating the trouble of loosening all the fixed supports 2 in steps, and helping to improve the efficiency of disassembling and replacing all the fixed supports 2.

[0055] When the skateboard 404 rotates clockwise following the driving wheel 4, the spring on the arc-shaped positioning shaft 108 is compressed. When the driving wheel 4 is released, the spring on the arc-shaped positioning shaft 108 loses the pushing and holding force from the skateboard 404, and automatically rebounds and pushes to drive the driving wheel 4 to rotate counterclockwise and reset, thereby controlling multiple F-shaped connectors 107 to slide back to their positions synchronously outward and engage with multiple plug posts 201 to implement plug-in positioning of the fixed support 2. Under normal circumstances, the spring on the arc-shaped positioning shaft 108 pushes the multiple F-shaped connectors 107 to maintain them in the plug-in positioning use state of sliding outward.

[0056] Through the power transmission of multiple second connecting rods 403 and drive wheels 4, the pushing and holding force of the spring on the arc-shaped positioning shaft 108 can be synchronously transmitted to multiple F-shaped connectors 107. This allows multiple F-shaped connectors 107 to share a spring on the arc-shaped positioning shaft 108 for pushing and holding positioning, eliminating the need to configure a spring for each F-shaped connector 107, which helps to simplify the overall structure of the fixed support structure to a certain extent and reduce the overall manufacturing consumables of the fixed support structure.

[0059] The bottom horizontal part of the L-shaped support plate on the fixed support 2 is plugged into the sink groove 104, which can implement shaking limit for the fixed support 2 as a whole to prevent the fixed support 2 from shaking as a whole on the top of the welding platform 1. When used together with the plug-in cooperation of the plug column 201 and the slot 105, it can significantly improve the installation stability of the fixed support 2.
