Description

Technical Field

[0001] This application belongs to the field of riveting technology, and particularly relates to a riveting device. Background Art

[0002] The existing riveting device is composed of a riveting machine, a vibrating disk feeder, and a conveyor line for transporting the riveting products. The riveting products are first fixed on the fixture by manual or robot, and then the fixture is transported under the riveting machine by the conveyor line to rivet the nut onto the product. However, in this riveting method, the conveyor line needs to stop indirectly. After the riveting machine finishes riveting, it runs again to transport the riveted products out and then transport the products waiting for riveting in. This indirect stop generates waiting time. Especially when the products are large, the waiting time is longer. Therefore, the existing riveting device can be further improved to make full use of time to improve work efficiency. Summary of the Utility Model

[0003] The technical problem to be solved by this utility model is to provide a riveting device to solve the deficiency that the indirect stop of the conveyor line in the prior art generates waiting time and does not make full use of time.

The two riveting guns are respectively installed on the mechanical hands of the two robots. Preferably, there are two groups of carriers, which are respectively rotatably installed on both sides of the frame. The carriers can be flipped to adjust the product angle. The frame is installed on the rotating table and is driven by the rotating table to rotate. Each group of carriers includes a chassis, a positioning tooling, a rotating shaft, a driving motor, and a tightening and positioning mechanism. There are two rotating shafts, which are respectively installed on both side surfaces of the chassis, and then the rotating shafts are rotatably installed in the frame. The positioning tooling is installed on the front surface of the chassis. The driving motor is located on one side of the frame. The output shaft of the driving motor is connected to one of the rotating shafts. The driving motor is a stepping motor, which rotates forward and backward to drive the chassis to rotate and change the angle of the positioning tooling. The tightening and positioning mechanism is used to limit and support the position of the chassis on the frame.

[0006] Furthermore, the positioning tooling includes a support panel, corner cylinders, and reverse positioning components. There are several corner cylinders, which are divided into two groups and are respectively located on the upper and lower sides of the support panel. There are two groups of reverse positioning components, which are respectively located on both sides of the support panel. The number and position of the corner cylinders and reverse positioning components can also be adjusted according to different products to be fixed.

[0007] Further, the reverse positioning component includes a cylinder, a reverse arm, and a pulling arm. There are two reverse arms, one end of which is hinged to the output end of the cylinder. There are at least two pulling arms, one end of which is respectively hinged to the outer cylinder of the cylinder, and the other end is hinged to the middle part of the adjacent reverse arm.

[0008] Further, the pressing and positioning mechanism includes a pressing cylinder and a pressing head. The pressing cylinder is installed on the chassis, and the pressing head is installed at the output end of the pressing cylinder. The other end of the pressing head abuts against the inner side surface of the frame; an anti-slip silica gel layer is provided on the outer surface of the pressing head. When the product is relatively heavy, it may cause the chassis to shake and become unstable. Therefore, the pressing and positioning mechanism is provided to stabilize the chassis on the frame.

[0009] Further, it also includes a partition protection plate on the frame and between two sets of carriers.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. The product of the present utility model adopts a rotating structure and is provided with two sets of carriers. One carrier is located directly below the robot for riveting. During the riveting time, the other carrier facilitates manual / machine to unload the riveted product and install the product waiting for riveting. When the product lowered by the robot is riveted, the rotating table rotates to adjust the positions of the two carriers, so that the carriers can be quickly replaced in a short time to carry out the next wave of riveting process, saving waiting time and improving work efficiency;

[0013] 2. The carrier can be flipped to adjust the riveting angle. For special-shaped products, some angles are required for riveting, so it can meet the riveting requirements of more products and has a wide application range. Description of the Drawings
