Description

Technical Field

[0001] The utility model relates to the technical field of iron chip cleaning devices, in particular to an iron chip cleaning device for a screw and nut feeding mechanism of an automatic assembly line. Background Technique

[0002] The degree of automation in the automotive manufacturing welding workshop is getting higher and higher. Screws and nuts have been automatically filled and replenished, and the screws and nuts are transported to the receiving end of the designated screw feeder by means of a feeding pipeline. The robot gripper carries a tightening gun to the receiving end of the screw feeder to grab the screws and nuts. During the grabbing process, the tightening gun needs to rotate 180° to the left and right to recognize the cap of the sleeve. During the rotation process, a large amount of iron chips are generated by the friction between the sleeve and the screw. If not cleaned in time, the accumulation of iron chips easily leads to the failure of cap recognition and causes downtime.

[0003] Currently, when cleaning iron chips, workers need to enter the automatic island and wipe and clean the iron chips and sundries with cotton cloth. Due to the small gap, it takes too much time, the labor intensity is high, and the cleaning effect is not good. During the wiping process, it is easy to touch the lubricating oil on the screw receiving slide rail of the screw feeder, resulting in unsmooth movement of the slide rail and causing secondary mistakes in nail picking.

[0004] Currently, when installing a pneumatic pressure regulating valve, the pneumatic pressure regulating valve is mostly fixed by bolts and mounting brackets. When the pneumatic pressure regulating valve fails, it needs to be disassembled and replaced. The replacement process of the pneumatic pressure regulating valve is relatively cumbersome and inconvenient to replace the pneumatic pressure regulating valve. Content of the Utility Model

[0005] The purpose of the utility model is to provide an iron chip cleaning device for a screw and nut feeding mechanism of an automatic assembly line, which has the characteristics of automatically cleaning iron chips, avoiding secondary mistakes in nail picking and being convenient for replacing the pneumatic pressure regulating valve.

[0007] A clamping mechanism is arranged inside the mounting seat.

[0008] In order to fix the pneumatic control valve, as an optimized iron filings cleaning device for the screw and nut feeding mechanism of the automatic assembly line of the present utility model, the clamping mechanism includes an inclined block slidably connected inside the mounting seat. The upper end surface of the mounting seat is penetrated and provided with two notches distributed front and back. A clamping plate is rotatably connected inside the notch. One end of the clamping plate extends above the mounting seat, and the other end of the clamping plate extends inside the mounting seat. A connecting plate slidably connected to the inclined block is fixedly connected to one side wall of the two clamping plates facing each other.

[0009] In order to facilitate driving the inclined block to move, as an optimized iron filings cleaning device for the screw and nut feeding mechanism of the automatic assembly line of the present utility model, a bolt is threadedly connected to the left side wall of the mounting seat. One end of the bolt extends inside the mounting seat and is rotatably connected to the inclined block.

[0010] In order to limit the inclined block, as an optimized iron filings cleaning device for the screw and nut feeding mechanism of the automatic assembly line of the present utility model, first sliding grooves are opened on the upper and lower end surfaces inside the mounting seat. First sliding blocks matching the first sliding grooves are fixedly connected to the upper and lower end surfaces of the inclined block.

[0025] As a technical optimization scheme of the present utility model, the clamping mechanism includes an inclined block 8 slidably connected inside the mounting base 1.

[0034] In this embodiment: The fixing blocks 17 facilitate the installation and fixation of the mounting seat 1.

[0035] Working principle: During installation, first fix the mounting seat 1 to the receiving end mechanism of the nail feeder through the fixing blocks 17;

[0036] Then move the pneumatic pressure regulating valve 2 between the two clamping plates 10, and then drive the inclined plane block 8 to move through the bolt 12. The inclined plane block 8 cooperates with the connecting plates 11 to push the lower ends of the two clamping plates 10 to both sides, so that the upper ends of the two clamping plates 10 approach each other, and further the two clamping plates 10 are in contact with the pneumatic pressure regulating valve 2, thereby fixing the pneumatic pressure regulating valve 2;

[0037] Then install the three-way joint 3 on the cross-moving cylinder air pipe at the receiving end of the nail feeder, then connect the pneumatic pressure regulating valve 2 and the three-way joint 3 through the air pipe 4.
