Description

Technical Field

[0001] The utility model belongs to the technical field of busbar processing, and particularly relates to a flexible automatic riveting mechanism for the production of flexible connection busbars. Background Technique

[0002] A busbar refers to the copper or aluminum bar connecting the main switch in the electric cabinet and the switches in each branch circuit in the power supply system. The surface is insulated, and its main function is to act as a conductor.

[0003] When processing the busbar, it is necessary to bend, electroplate and rivet the busbar. At present, the busbar riveting process is mainly carried out manually. The worker holds the busbar, aligns the riveting hole position with the riveting gun on the riveting machine, and then operates the riveting machine to press the rivet. However, manual riveting has high requirements for the quality of the operator. If the operation method of the worker is incorrect, the busbar may not be flat relative to the lower die. Direct riveting will cause the product not to be flat with the riveting lower die. Due to tolerance reasons, the bending angle of the busbar will cause an angle between the riveting surface and the riveting lower die. The rivet or nut pressed in may be offset and the riveting is poor. When there are multiple riveting hole positions, there may be a situation of missed riveting. At the same time, the manual riveting method not only has a large labor intensity for workers, but also has a low production efficiency. Content of the Utility Model

[0004] Purpose of the utility model: To overcome the above deficiencies, the purpose of the utility model is to provide a flexible automatic riveting mechanism for the production of flexible connection busbars. The automatic riveting mechanism designed by the utility model places the busbar workpiece on the anvil, positions the workpiece through the riveting positioning protrusions on the anvil, and after the photoelectric sensor senses the workpiece, the pressing cylinder acts to drive the pressing plate to press the riveting part of the busbar to make it flat with the anvil, and then the riveting gun acts to press the rivet or nut. The rivet or nut has a better concentricity with the reserved riveting hole of the product. This automatic riveting mechanism realizes the automatic riveting of the busbar and reduces the labor intensity of workers.

[0005] Technical solution: To achieve the above purpose, the utility model provides a flexible automatic riveting mechanism for the production of flexible connection busbars, which includes a frame, a positioning and pressing component, and a riveting component. The positioning and pressing component is arranged on the frame, and the riveting component is arranged above the positioning and pressing component;

[0006] The positioning and pressing component includes an anvil, a pressing cylinder and a pressing plate. The pressing cylinder and the anvil are arranged on the frame, the pressing plate is connected with the pressing cylinder, and the pressing plate is located above the anvil;

[0007] The riveting component includes a nail feeding gun, a nail feeding box and a riveting gun. The nail feeding gun is connected with the nail feeding box, a riveting hole is arranged on the nail feeding box, and the nail feeding gun is arranged directly above the riveting hole.

[0008] Further, the anvil includes a riveting portion and a supporting portion. The riveting portion is provided with a riveting positioning protrusion on its upper surface. The supporting portion is provided with a photoelectric sensor for sensing whether the workpiece is in place, and a supporting spring is also arranged on the supporting portion. The riveting positioning protrusion limits the workpiece on one hand and cooperates with the riveting gun to press the rivet into the workpiece on the other hand. The supporting spring plays a flexible supporting role for the non-riveted part.

[0009] Further, a nail feeding channel is arranged in the nail feeding box. One end of the nail feeding channel is connected to the nail feeding gun, and the other end leads to the riveting hole.

[0010] In a preferred embodiment, the riveting assembly further includes a connecting assembly. The nail feeding box is connected to the machine frame through the connecting assembly. The connecting assembly includes a first connecting rod and a second connecting rod. The first connecting rod is fixedly arranged on the machine frame, the second connecting rod is connected to the nail feeding box, and waist-shaped holes are arranged on both the first connecting rod and the second connecting rod, and they are connected by bolts passing through the waist-shaped holes. The installation height of the nail feeding box can be changed by installing the bolts at different positions of the waist-shaped holes.

[0011] Further, the nail feeding gun is a pneumatic nail feeding gun, and the nail feeding gun is connected to a blower and a nail storage container; a U-shaped notch is formed on the pressing plate, and the U-shaped notch is located directly below the riveting gun.

[0012] Furthermore, transfer robots are arranged on both sides of the automatic riveting mechanism, and a clamping device for clamping the workpiece is arranged at the end of the transfer robot.

[0013] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects:

[0014] 1. The purpose of the present utility model is to provide a flexible automatic riveting mechanism for the production of soft connection busbars. The automatic riveting mechanism designed in the present utility model places the busbar workpiece on the anvil, positions the workpiece through the riveting positioning protrusion on the anvil. After the photoelectric sensor senses the workpiece, the pressing cylinder acts to drive the pressing plate to press the riveting part of the busbar to make it flat against the anvil, and then the riveting gun acts to press in the rivet or nut. The rivet or nut maintains a better concentricity and coaxiality with the pre-reserved riveting hole of the product. This automatic riveting mechanism realizes the automatic riveting of the busbar and reduces the labor intensity of workers.

[0015] 2. The present utility model can flexibly ensure that the riveting surface of the soft connection busbar is flat against the nut. Since the soft connection part is suspended and is pressed by the cylinder, it will not form an angular gap with the lower die due to gravity, and the rest of the suspended part will not form an angle between the riveting surface and the lower die due to gravity, further improving the riveting quality.

[0016] 3. The pressing plate in the present utility model only acts on the riveting part of the workpiece, has no requirements for the shape and hardness of the product, and is not affected by the shape and form of the product. Description of the Drawings
