Description

Technical Field

[0001] The utility model relates to tooling equipment, in particular to a double-gripping turning table used in a welding production line for automobile floors. Background Art

[0002] In the process of manufacturing automobile body-in-white, operating robots are usually used on the assembly line to clamp parts for automated processing operations. On the welding production line, the automobile floor is a typical processing part, which is usually processed for panel parts. In the processing of panel parts, it is necessary to process both the front and back sides of the panel parts. The existing operating robots often clamp one side and process the other side. After the panel part is processed on one side, it needs to be turned over. The operating robot needs to change the clamping surface to process the other side. On the existing assembly line, the flipping process is often achieved by switching the clamping between two operating robots. However, on the one hand, this method requires the configuration of multiple robots for operation, which is complex and inefficient. On the other hand, the positioning accuracy is low during the flipping process, which affects the accuracy of the subsequent operation on the other side of the panel part. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing turning mechanism is complicated to operate, inefficient and has low turning positioning accuracy. The utility model provides a double-grip turning table for an automobile floor welding production line to solve the above problems.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a double-grip turning table for an automobile floor welding production line, used for turning over and clamping a panel part, comprising a clamp body, the clamp body having two clamping stands arranged in parallel and at intervals, the panel part being placed between the two clamping stands, each of the clamping stands being provided with a clamping mechanism, the clamping mechanism clamping and fixing the panel part; the clamping mechanism comprising a clamping frame, a fixed clamping claw fixed on the clamping frame and a rotating clamping claw rotatably installed on the clamping frame; the end of the rotating clamping claw is rotatably hinged on the clamping frame, and its top end is in conflict with the top end of the fixed clamping claw.

[0005] Furthermore: A positioning mechanism is arranged on the clamp body below the panel member, and the positioning mechanism includes a positioning arm rotatably hingedly arranged on the clamp body, a positioning pin is installed at the end of the positioning arm, and the positioning arm rotates on the clamp body and inserts the positioning pin into the positioning hole on the panel member.

[0006] Furthermore: the clamping mechanism also includes a clamping drive cylinder for driving the rotating clamping claw to move, and the positioning mechanism also includes a positioning drive cylinder for driving the positioning rotating arm to move.

[0007] Furthermore: the clamping stand is a triangular structure that is narrow at the top and wide at the bottom, and the operating robot grabs the panel member through a double-sided clamp.

[0008] The beneficial effect of the utility model is that a double-grip turning table for an automobile floor welding production line is applied to the present invention. By setting a transition station, an operating robot is first positioned and clamped in the transition station. The operating robot first releases the panel part, and then the operating robot itself switches the clamping surface to achieve the flipping and clamping of the panel part. There is no need to switch clamping between multiple operating robots, and the operation efficiency is high. The panel part can be accurately positioned on the double-grip turning table, and the flipping clamping has a high clamping accuracy, which is beneficial to the subsequent reprocessing of the panel part.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, in the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0017] Any process or method description in the flowchart or otherwise described herein may be understood to represent a module, fragment or portion of code that includes one or more executable instructions for implementing the steps of a specific logical function or process, and the scope of the preferred embodiments of the present invention includes alternative implementations in which functions may not be performed in the order shown or discussed, including performing functions in a substantially simultaneous manner or in the reverse order depending on the functions involved, which should be understood by technicians in the technical field to which the embodiments of the present invention belong.

[0018] like Figures 1 to 4 As shown, the utility model provides a double-grip turning table for an automobile floor welding production line, which is used for turning over and clamping a panel member 1, and includes a clamp body 2, wherein the clamp body 2 has two clamping stands 3 arranged in parallel and spaced apart, and the panel member 1 is placed between the two clamping stands 3, and each of the clamping stands 3 is provided with a clamping mechanism 4, and the clamping mechanism 4 clamps and fixes the panel member 1; the clamping mechanism 4 includes a clamping frame 5, a fixed clamping claw 6 fixed on the clamping frame 5, and a rotating clamping claw 7 rotatably installed on the clamping frame 5; the end of the rotating clamping claw 7 is rotatably hinged on the clamping frame 5, and its top end is in conflict with the top end of the fixed clamping claw 6.

[0019] A positioning mechanism 8 is provided on the clamp body 2 below the panel member 1. The positioning mechanism 8 includes a positioning arm 9 rotatably hingedly provided on the clamp body 2. A positioning pin 10 is installed at the end of the positioning arm 9. The positioning arm 9 rotates on the clamp body 2 and inserts the positioning pin 10 into the positioning hole on the panel member 1.

[0020] The clamping mechanism 4 further includes a clamping drive cylinder 12 for driving the rotating clamp 7, and the positioning mechanism 8 further includes a positioning drive cylinder 11 for driving the positioning rotating arm 9. The clamping stand 3 is a triangular structure with a narrow top and a wide bottom, and the operating robot grabs the panel 1 through a double-sided clamp.

[0021] The double-claw flipping table is arranged in the production line, and is used for flipping and clamping the panel part 1 for processing. That is, after the operating robot grabs the panel part 1 to complete processing on one side during production, the operating robot will flip and clamp the panel part 1 through the transition of the double-claw flipping table, so that the other side of the panel part 1 can be subsequently processed in the subsequent process.

[0022] The specific working process is that when the operating robot needs to turn over the clamped panel part 1, it first moves the clamped panel part 1 between the clamping stands 3, drives the positioning arm 9 to rotate through the positioning drive cylinder 11, and inserts the positioning pin 10 into the positioning hole on the panel part 1, thereby completing the positioning of the panel part 1 relative to the double-grasp turning table, and then the clamping mechanism 4 works, and the clamping drive cylinder 12 drives the rotating jaw 7 to move, and the rotating jaw 7 and the fixed jaw 6 jointly clamp and fix the panel part 1, thereby completing the positioning and fixing of the panel part 1 and the double-grasp turning table through the clamping mechanism 4.

[0023] After the panel part 1 is fixed to the double-grasp turning table, the double-sided clamp of the operating robot releases the connection with the panel part 1, and then the operating robot grabs the panel part 1 from the other side of the panel part 1, so that the double-sided clamp will complete the fixed connection with the panel part 1 from the other side. Finally, the clamping mechanism 4 and the positioning mechanism 8 on the double-grasp turning table will release the clamping and positioning of the panel part 1 under the action of the positioning drive cylinder 11 and the clamping drive cylinder 12. The operating robot can move the panel part 1 away so as to move to the next operation process and start processing on the unprocessed side of the panel part 1, so that the turning and clamping of the panel part 1 can be completed.

[0024] This mechanism is actually a transition mechanism set up in the production line, and in the process of turning over the panel part 1, the double-grab turning table and the panel part 1 have a reliable and precise positioning and clamping mechanism. After loosening the panel part 1, the operating robot can flexibly and freely turn over and clamp the panel part 1 with the double-sided clamp. After turning over and clamping, a high clamping accuracy can be guaranteed, avoiding the tedious operation of transferring clamping between different operating robots in the prior art, and at the same time having a high turning efficiency.
