Description

Technical Field

[0001] The utility model belongs to the technical field of tooling parts and relates to an angle code riveting tooling. Background Art

[0002] Angle brackets are hardware that connect components that intersect at 90 degrees. The model, form and material type of the angle bracket are determined according to the force applied to the connected components. The installation and connection of many large aluminum panels are achieved by riveting multiple angle brackets on their edges.

[0003] For example, a solid rivet connection device disclosed in the patent with authorization announcement number CN202752529U comprises an angle code (1), an air hammer (2), an iron block (3) and a solid rivet (4); a driving assembly (2-1) is arranged inside the air hammer (2); a striking head (2-2) is arranged at the head of the air hammer (2); a spring (2-3) is arranged on the striking head (2-2); an exhaust port (2-4) and an air inlet (2-5) are arranged at the lower end of the handle of the air hammer (2); the solid rivet (4) is arranged at the top of the striking head (2-2) of the air hammer (2); the solid rivet (4) passes through the angle code (1); and an iron block (3) is arranged at one end of the solid rivet (4).

[0004] The above-mentioned device can provide support for the stressed rivet by arranging the iron baffle behind the angle code, so that the angle code and the workpiece can be riveted together after the rivet is deformed. However, there are still some shortcomings: the above-mentioned iron baffle relies on the support of the operator's hand when in use. When impacted by an air hammer, the iron baffle is easy to move backward quickly, causing impact on the operator's hand and causing injury. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides a corner code riveting tool. The technical problem to be solved by the utility model is that the prior riveting tool has poor safety.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A corner code riveting tool comprises a rear block, wherein the rear block is in a rectangular shape and has two spaced-apart positioning arms, the positioning arms are in an L shape and a gap is formed between the positioning arms and the side wall of the rear block.

[0008] One side of the angle code is fitted with the flange of the edge of the workpiece to be riveted, and the solid rivet is penetrated along the thickness direction of the flange. During riveting, the flange and the angle code are inserted from bottom to top into the gap between the positioning arm and the rear stopper to form a positioning. The angle code is arranged between the two positioning arms, and the rear stopper and the positioning arm are respectively arranged on both sides of the flange. One end of the solid rivet is stably against the rear stopper. In this way, when the air hammer impacts the other end of the solid rivet to rivet the flange and the angle code, the rear stopper is forced to move backward, but due to the constraints of the two positioning arms, the position of the rear stopper is always stable within a smaller range. When the operator holds the rear stopper tightly, the rear stopper will not be forced to fall out and cause injury to the operator's hands.

[0009] In the above-mentioned angle bracket riveting tool, the positioning arm includes a connecting section and a positioning section bent relative to the connecting section, and the connecting section is located on the side wall of the rear block opposite to the positioning section. In this way, when the side where the connecting section and the positioning section are connected abuts against the upper edge of the flap, the flap will still have a certain distance from the side edge of the rear block, which is conducive to the angle bracket that exceeds the flap being still shielded by the rear block, avoiding the operator's hand being partially embedded between the rear block and the angle bracket and being squeezed and injured during processing.

[0010] In the above-mentioned angle code riveting tool, the end of the positioning section away from the connecting section is spaced from the side edge of the rear block along the length direction of the positioning section. In this way, when the rear block cooperates with the flap, the positioning arm only needs to be lifted to a lower height to achieve assembly, which is convenient to operate and also helps to ensure that the positioning arm is not easily deformed by force, thereby improving the structural stability.

[0011] In the above-mentioned corner bracket riveting tool, the end of the positioning section away from the connecting section is subjected to rounded or chamfered transition treatment, so that the transition surface can provide a guide when the tool is plugged and matched with the flange and the corner bracket, making the operation smooth and convenient.

[0012] In the above-mentioned angle code riveting tool, the dimension between the two side walls of the rear stopper along the length direction of the connecting section is larger than the dimension of the positioning arm along the length direction of the connecting section. This is conducive to arranging the center of gravity of the tool as a whole to one side of the rear stopper, so that the state of the operator's auxiliary hand pressing the rear stopper is more stable.

[0013] In the above-mentioned angle code riveting tool, the rear block is a steel material piece or an aluminum alloy material piece. The steel material piece has excellent hardness and strength and low material cost, and the aluminum alloy material piece has excellent strength and is conducive to reducing the overall weight, which is convenient for users to operate and take.

[0014] Compared with the prior art, the advantages of the utility model are as follows:

[0015] The angle code riveting tool utilizes the angle code installation environment to transfer the impact force on the rear block to the workpiece to be installed via the positioning arm, thereby avoiding excessive impact of the rear block on the operator's hand and effectively improving safety.
